The Smoking system 21 in accordance with the invention is shown in Fig.1 and 2. The system includes a cigarette 23 and a lighter 26 reusable. The cigarette 23 is inserted and removed from the holes 27 in the front wall 29 of the lighter 25. The Smoking system 21 is used as a normal cigarette. The cigarette 23 is produced after one or a few puffs. Lighter 25 take more puffs than the cigarette 23.
Lighter 25 includes a housing 31 and has front and rear parts 33 and 35. The power source 37, the feeding elements to heat the cigarette 23 is in the rear part 35 of the lighter 25. The rear part 35 easily opened and closed, for example, with screws or clips for easy replacement of the power source 37. In the front part 33 posted by the heating elements and circuits connected to the power source 37 in the rear part 35. The front part 33 is easily connected to the rear part 35, for example, the type of dovetail or slides. The housing 31 is made of durable heat-resistant material on the base metal or, preferably, is 10,j,8x1,5 see
The energy source 37 must provide food items, heating the cigarette 23. Preferably the source 37 is replaceable and rechargeable, for example, a capacitor or a better battery. In a preferred embodiment of the invention the power source is replaceable recharged the battery (four series-connected Nickel-cadmium cell) voltage without load from 4.8 to 5.6 Century, However, the parameters of the source 37 are selected taking into account other elements of the Smoking-room system, first of all heaters. In U.S. patent N 5.144.962 cited as reference, describes several types of power sources used for Smoking system according to the present invention, for example, rechargeable batteries and bystrorastvorimye capacitors with charge from the battery.
Essentially cylindrical heating unit 39 to heat the cigarette 23, which preferably also holds the cigarette in place relative to the lighter 25, and the electric circuit 431 controlling the supply of a given amount of energy from the source 37 to the heating elements (Fig.1 and 2 is not shown) is preferably placed in the front part 33 of the lighter. In the preferred dictionary elements 43 (Fig.3A), which are separately supplied from source 37 under control circuit 41 for heating the eight sites around the cigarette 23 and receive eight puffs of fragrant smoke. Although it may be a different number of heating elements 43, preferably there should be eight, not least because a normal cigarette is designed for eight puffs and because the eight elements are manageable binary devices.
Scheme 41 preferably is driven from the sensor 45 puffs (Fig. 2), triggered by a pressure drop, or modify the flow of air when the smoker puffs on his cigarette 23. The sensor 45 is located in the front part 33 of the lighter 25 and communicates with the cavity inside the heating unit 39 around the cigarette 23 through the channel 47 in the spacer 49 and the support 50 of the heating block, or through a tube (not shown). The sensor 45, suitable for use in the Smoking system 21 described in U.S. patent N 5.060671, the disclosure of which is attached as references, they may be silicon sensor model 163PC01D35 produced by the Department of Microswitch" company "Honeywell, Freeport, Illinois, which actuates a suitable heating element 43 as a result of changes giving the e thermoanemometer, which actuate the corresponding heating element 43 when changing air flow.
The indicator 51, preferably located on the outside of the lighter 25, preferably on its front wall 33, shows the number of inhalations remaining in the cigarette 23 is inserted into the lighter. The indicator 51 preferably includes a liquid crystal display of seven parts. In a preferred embodiment of the invention, the indicator 51 shows the number "8" when the light beam emitted by the photodetector 53 (Fig.2), is reflected from the front end of the newly inserted cigarette 23 and detected by a photodetector. The photodetector 53 is preferably installed in the hole 55 in the spacer 49 and the support 50 of the heating unit 39 (Fig.3A). The photodetector 53 sends a signal to the circuit 41, and that, in turn, the indicator 51. The number "8" on the display means 51 that of the cigarette 23 you can make eight puffs, i.e. none of the heating elements it has no effect. After the cigarette 23 smoked to the end, the indicator displays the number "0". After removal of the cigarette 23 in the lighter 25, the photodetector 53 does not detect its presence, and the indicator 51 is turned off. The photodetector 53 is configured so that it does not radiate the settlement of the sector type OPR5005 firm "OPTEK technology, Inc., Carrolton, Texas.
The LCD display can also indicate the voltage drop in the battery is below a preset low level, for example, by alternately turning on and off the display and return to the specified high level as a result of razoredge. Given the low level may be about 3-3,5 B, and given a high level - about 5 - 6 B.
The supply of electricity to the selected heating element may be in the form of pulses of a given duration, generated by the control circuit. The pulse duration may be, for example, from about 1 to about 3 or from about 1 to about 2, depending on the amount of energy that should be applied to the selected heater.
Instead of the photo detector 53 for detecting the presence or absence of a cigarette 23 can be used a mechanical switch (not shown), and the reset circuit 41, when the lighter is inserted a new cigarette, can serve as a button (not shown), exposing the figure "8" on the display 51, etc. energy Sources, electronic circuits, sensor puffs and indicators applicable to the Smoking system 21 of the present invention, described in patientpractitioner closed for the passage of air while Smoking.
Preferred cigarette 23 for Smoking system 21 shown in Fig. 4A and 4B, although the cigarette and may be any shape that allows the formation of fragrant tobacco smoke for delivery to the smoker when heated cigarette elements 43. Cigarette 23 includes tobacco tape 57, consisting of the substrate or chamber 59, which is marked flavored tobacco material 61, preferably tobacco. The carrier is made in the form of a cylinder and has an inner and outer surface. Tobacco tape 57 is wrapped around a cylindrical reverse control (feedback filter) 63 at one end and a cylindrical first direct filter 65 at the opposite end. First direct filter 65 is a filter type "free tube, having a longitudinal axial channel 67, so that the resistance when tightening small.
If desired, on top of the tobacco belt 57 can be wrapped in cigarette paper 69. This is an easy paper, preferably coated with tobacco flavoring, or paper-based tobacco to enhance the sense of taste. On paper 69 can be applied in concentrated or diluted liquid extract. Wrapping paper 69 preferably has a minimum density and tol is otnesti (at a relative humidity of 60%) 20 - 25 g/m2the minimum permeability 0-25 CORESTA (cm3air passing through 1 m2material for 1 minute at a pressure drop of 1 kPa), a tensile strength of 2000 g/27 mm wide (1 inch/min), a thickness of 1.3 - 1.5 mils (0,033 - 0,038 mm), the content of CaCO35% , citrate 0%. Preferably the material for wrapping paper contains 75% of tobacco leaf (non-cigarette, traboulay or traboulay and shadow drying, filling and light middle vein). It can also be a plain linen paper density 15 - 20 g/m2or this paper impregnated with the extract. A binder in the form of lemon pectin is added in a quantity less than or equal to 1%. You can add glycerin in an amount not greater than necessary, to obtain the stiffness of the paper the same as in regular cigarettes.
The cigarette 23 is also preferably includes a cylindrical double filter 71, preferably of the usual type RTD (resistance to tightening), and a cylindrical second straight filter 75. Filters are double bonded paper 75, which extends beyond the end of the second direct filter 73 and is attached to the wrapping paper 69 so that the end of the first direct filter 65 is adjacent to the end face of the second direct filter 73. Like the first filter 65 second is Tr 65 form together with the tobacco ribbon 57 cavity 79 inside the cigarette 23.
The internal diameter of the longitudinal channel 77 in the second direct filter 73 is larger than the inner diameter of the channel 67 in the first direct filter 65. Preferably the internal diameter of the channel 67 is 1-4 mm, and channel 77 - 2-6 mm. Was found that the different diameters of the channels 67 and 77 facilitate good mixing or turbulence between fragrant tobacco smoke generated from the heated flavored tobacco material, and the air entering the cigarette 23 from the outside when tightening, resulting in double filter 71 is supplied at a higher aerosol mixture. In the cavity 79 of fragrant tobacco smoke, formed by heating tobacco 61, is predominantly in the vapor phase, but when mixed in the channel 77 it turns into a visible aerosol. Along with the first direct filter 65 having a longitudinal channel 67, other choices are possible mixing of the vapor phase of tobacco smoke with the incoming air, for example, first direct filter can be provided with small apertures, i.e., made in the form of a honeycomb or perforated metal plate.
Air enters the cigarette 23 mainly through tobacco tape 57 and wrapping paper 69 transverse or radial, rather than lengthwise through the inverse filter of the deposits. When the longitudinal flow of air into the cigarette 23 fragrant tobacco smoke produced by heating the tobacco belt 57 radially placed around her elements 43, is not completely removed from the cavity 79. Therefore, it is preferable that the formation of fragrant tobacco smoke was completely dependent on the structure of the tobacco belt 57 and energy levels, served on the heating elements 43. Therefore, the flow of air into the cigarette longitudinal through an inverse filter 63 when Smoking should be minimal, with the exception of the first tightening. Return filter 63 also minimizes the opposite end of the spray from the cavity 79 after heating flavored tobacco material 61, minimizing thereby the risk of damage to these aerosol components plug 25.
The carrier 59, which caused flavored tobacco material 61, distinguishes the material from the heating elements 43, the transfer of heat from the heating elements to the material and retains the integrity of cigarettes after Smoking. Preferably the carriers 59 include a Mat of non-woven carbon fiber because of its high heat resistance. Such carriers are described in the application U.S. N 07/943.747 dated September 11, 1992, cited as SimpleTest from about 6 g/m2to about 12 g/m2and in diameter from about 47 microns to about 30 microns. The length of the fibers allows the Mat to withstand tensile stresses during processing. Preferably mats include a binder suitable for use in electric Smoking products.
As carriers 59 can be used for light metal sieve or perforated foil. For example, applies a sieve weight in the range from about 54 g/m2to about 15 g/m2and wire diameter in the range from about 0.038 mm to about 0,076 mm In another embodiment, the sieve is made of foil (e.g. aluminum) thickness 0,0064 mm hole diameter ranging from about 0.3 mm to about 0.5 mm, which reduce the mass of the foil at from about 30% to about 50%, respectively. Preferably these openings are staggered or intermittently (i.e., at random) to reduce lateral heat ablation of flavored tobacco material 61.
Such a metal sieve or foil is introduced into a cigarette 23 in a variety of ways, such as (1) lubricate the tobacco suspension ribbon and place a sieve or foil on a wet slurry, and then dried, (2) attach a sieve or a foil to the tobacco sheet or Mat. From the media it should not directly in contact with them. Preferably the metal carrier 59 is isolated from the electrical heating elements 43 appropriate binder or lightweight paper, such as wrapping paper 69.
Tobacco tape 57 get on the technology of making paper. In this process, a strip of tobacco washed with water. Soluble components are further used in the coating. From the extracted tobacco fibers do basic math. Carbon fiber is dispersed in water and add sodium alginate. Instead you can use any other hydrocolloids that are not in fragrant tobacco smoke, soluble in water and have sufficient molecular weight to impart durability tobacco belt 57. The dispersion is mixed with a suspension of extracted tobacco fibers, and, optionally, flavoring substances. The resulting mixture was spread on a long net and passed through the paper machine to the base tape. Soluble substances are removed when washing the strips of tobacco, put on one side of the substrate with the help of reverse balavage machine after drying cylinder. The ratio between the soluble components of tobacco and tobacco dust is from 1:1 to 1:20. Suspens machine. During the operation of coating or after it add flavouring substances taken in by the tobacco industry. To improve the wettability add 0.1 to 2.0% pectin or other hydrocolloid.
If any media type 59 printed on its inner surface flavored tobacco material 61 emits a fragrant smoke when heated and may stick to the surface of the carrier. Such material may include sheets, foams, gels, dried suspension or spray dried slurry, which preferably, but not necessarily contain tobacco or derived from substances that are examined in more detail in the application U.S. N 07/943.747.
Preferably the tobacco belt 57 while processing add a humectant, such as glycerin or propylene glycol in the amount of 0.5 - 10% by weight of the tape. Humidifier promotes the formation of a visible aerosol, serving as the initiator for him. When the smoker exhales aerosol containing flavored tobacco smoke and the humidifier, the latter condenses in the atmosphere, creating the appearance of an ordinary cigarette smoke.
Because flavored tobacco material 61 is located on the surface of the carrier 59, the properties of revealing element 43, may contain one number or type of flavoring, and in front of another element - a very different number or kind of flavoring. Thus, the aroma coming to the smoker to tobacco smoke can be selected individually by applying different areas of flavored tobacco material on the surface of the carrier. The smoker can, for example, different install a cigarette 23 relative to the stationary heating elements in the lighter 25, if he wants to get a certain flavor.
In addition, the nature of fragrant tobacco smoke can be changed by applying a controlled amount of energy to the heating elements 43. For example, if the first heating element filed more energy (20 j) than the second (15 j), the first creates a higher temperature than the second, and accordingly, the smoke is more flavored. Thus, changing the flow of energy, you can control the intensity of flavor with each puff.
Cigarette 23 preferably has the same diameter along the entire length of about 7.5 to 8.5 mm as a conventional cigarette that gives smokers the familiar sensation in the mouth when using the Smoking system 21. In predpochtitelnei machines. The total length of the double filter 71 and the second direct filter 73 is preferably 30 mm, Such as paper 75 comes to 5 mm beyond the end of the second direct filter 73 on top of the tobacco belt 57. The length of the tape 57 is preferably 28 mm Tape 57 rests on the ends on the back of the filter 63 and the first direct filter 65 length of 7 mm each. The length of the cavity 79 formed tobacco tape 57, the inverse filter 63 and the first direct filter 65 - 14 mm
When the cigarette 23 is inserted into the hole 27 in the first wall 29 of the lighter 25, it abuts, or nearly abuts, in the inner bottom surface 81 of the spacer 49 of the heating unit 39 (Fig. 3A) near the channel 47, connected to the sensor 45 puffs and a hole 55 for the photo sensor 53. In this position, the cavity 79 of the cigarette 23 is adjacent to the heating elements 43, and the rest of the cigarette, including a second straight filter 73 and double filter 71 is outside of the lighter 25. The sections of the heating elements 43 is inclined radially inwards ensuring the holding of the cigarette 23 in place relative to the lighter 25 and the heat transfer to the tobacco belt 57 directly or through brown paper 69. Cigarette 13 is compressed so that the heating elements 43 pressed into it. 4A and 4B wrapping paper 69 and tobacco tape 57 permeable enough to create the desired resistance, and tightening the air enters into the cavity 79 radially or tangentially through the paper and tape. As already noted, permeable reverse filter 63 can supply the air into the cavity 79 longitudinally.
If desired, the transverse flow of air into the cavity 79 can be facilitated through radial holes (not shown) in wrapping paper 69 and tobacco belt 57 in one or several places. Such drilling contribute to the smoke and the formation of aerosol. In tobacco the ribbon 57 is made holes with a diameter of 0.4 to 0.7 mm with a density of approximately 1 hole 1 to 2 mm2. This creates porosity in the 100-500 CORESTA. The permeability of wrapping paper 69 is preferably from 100 to 1000 CORESTA. Of course, to provide the desired properties, resistance to traction, the density of holes and their diameter may be distinctive from those described above.
The cross-flow of air into the cavity 79 is facilitated also by the implementation of through holes (not shown) in wrapping paper 69 and tobacco belt 57. In the manufacture of cigarettes 23 or holes are drilled right through the paper 69 and the tape 57, either made by the cauldron in Fig. 3A-3B. Modification of the heating unit 39A performed together with the spacer and support shown disassembled in Fig. 5. Element 49A of the heating unit 39A replaces the spacer 49 and the support 50 of the heating unit 39 in Fig. 3A. The function of the reception of a cigarette 23 and placement of elements for heating can be performed and other structures of the heating unit, as shown in Fig. 3A-3B and 5.
In Fig. 3A-3B, the heating unit 39 is placed in the hole 27 of the lighter 25.

The lower inner surface 81 of the spacer 49 serves as a stop for the cigarette 23 in the heating unit 39, providing the fit of the heating elements 43 to the cavity 79 of the cigarette. In the heating unit 39A (Fig. 5) support for the cigarette 23 is lower inner surface 81A of Bemelen a sliding fit. Front edge 93 of the cap 83 is flush or slightly in favour of the first wall 39 of the lighter 25 and beveled or rounded inward to facilitate the introduction of a cigarette 23 in the heating unit 39. The sections of the heating elements 43 of the heating unit 89 and the pin 95 pin block 91 is fastened around the outer surface 97 of the spacers 49 landing friction with the ring 99. Rear ends 101 of the heating elements 43 and rear ends 103 pairs of pins 95 are welded to the pins 104, firmly planted at the bottom outer surface 105 (Fig. 3B) support 50 through openings 107 and acting for it, which serve to connect with the control circuit 41 and a power source 37. The pins 104 are firmly bonded to the support 50 so that does not allow the air to pass through the openings 107. The pins 104 are inserted in corresponding slots (not shown), thus forming a support for the heating unit 39 within the lighter 25 and from the nests to the different elements are wires or tracks of the PCB. The other two pins 95 provide additional support pin block 91. The channel 47 in the spacer 49 and the support 50 informs the sensor 45 puffs and the photodetector 53 about the presence or absence of a cigarette 23 in the lighter 25.
Similarly, in the heating unit around the outer surface 97A element 49A landing friction with the ring 99. Rear ends 101 of the heating elements 43 and rear ends 103 preferably two pins 95 are removed through the lower outer surface 105A element 49A to connect to the circuit 41 and the power source 37.

If desired, narrow sections 127 of each of the heating elements 43 at the rear ends 101 provided with lugs 129 for soldering to the pins 104 or insertion in a socket (not shown) for connection to the circuit 41. The workpiece 115 process then laser cut with getting serpentine "print" 131 (Fig. 6 and 8) at the widest part 125. Optionally prints 131 can be cut immediately upon receipt of the workpiece 115.
Cut or stamped sheet is subjected to electrical discharge machining to smooth edges of individual heating elements 43 that allows you to insert a cigarette 23 in the lighter 25 without difficulty. Then the sheet is rolled on a mandrel (not shown), giving it a cylindrical shape. Signalreaderror node 89 (Fig. 6).
Heating the node 89 can also be made any other way. For example, heating the node 89 receive, first bending the sheet into a tube (not shown), and then slicing it on a separate heating elements 43. Or it is collected, attaching the individual elements 43 spot welded to a common ring (not shown), which serves as an electric bus, and mechanical support for the heating elements like the front part 121. You can also weld or otherwise attach the front portion 121 of the heating unit 121 to abiemnom ring (not shown) whose inside diameter corresponds to the diameter of the cigarette 23. It helps to maintain the cylindrical shape of the heating unit and gives added strength.
Pin block 91 (Fig. 9) receive any of the same methods as heating the node 89. As the heating site 89, individual pins 95 and stripes for the front end 135 of the pin block 91 also cut from a flat sheet of electrically conductive material is rolled and welded, receiving cylinder. The internal diameter of the pin block 91 is essentially equal to the outer diameter of the heating unit 89. Then the front part of the heating unit 121 89 of stable the re pins 95 are located in the openings between adjacent pairs of heating elements 43. As can be seen from Fig. 3B, four pin 95 (of which only two are electrically connected with the pins 104, passing through the bearing 50) placed radially through 22,5oC the circumference relative to the eight heating elements 43, and the connecting pins 104 pass through the support.
Various embodiments of the lighter 25 in accordance with the present invention make it possible to deliver the smoker enough to tobacco smoke under normal conditions.
In particular, for 8 puffs smoker should get 5 - 13 mg fragrant tobacco smoke, preferably 7 to 10 mg, with each puff has a volume of 35 ml and the duration of 2 C. For this purpose, the heating elements 43, transferring heat to the cigarette 23, should have a temperature of from about 200oto about 900oC and consume from 5 to 40 j of energy, preferably 10 to 25 j, optimally about 15 joules. Power consumption less than those of the heating elements 43, which are tilted toward the cigarette 23, which improves thermal conductivity.
The heating elements 43 must have an active surface of about 3 to 25 mm2and resistance from 0.5 to 3.0 Ohms, preferably 0.8 to 2.1 Ohms. The resistance of the heater elements 43 for the REM series-connected Nickel-cadmium cells voltage without load 4,8 - 5,8 B. If such elements six or eight, then the resistance of the heater elements 43 should be 3 - 5 Ohms or 5 to 7 Ohms, respectively.
The material of the heating elements 43, must ensure that the time between failures is at least 1800 starts. The heating unit 39 25 lighters replaced separately from the energy source 37 and the control circuit, in which the minimum time to failure 3600 cycles or more. When choosing the material for the heating elements are also taken into account the resistance to oxidation and low reactivity in General, so that he did not enter into reaction with a cigarette 23 in all possible temperatures. The heating elements 43 can be enclosed in the insulation of inert heat-conducting material such as ceramic, in order to avoid unwanted reactions.
Based on these requirements, the material for heaters can be a doped semiconductor (e.g. silicon), carbon, graphite, stainless steel, tantalum, ceramics and metal alloys based on Nickel, chromium and iron.
Silicon doped with phosphorus to a level 51018- 51019the impurity atoms/cm3that corresponds to a specific fight the silicon - aluminum and silicon carbide - titanium. Suitable also resistant to oxidation of intermetallic compounds, for example, aluminides of Nickel and iron.
Preferably, however, manufacturing heating elements 43 of the heat resistant alloy with high mechanical strength and resistant to fracture surfaces at high temperatures. Preferable materials that maintain high strength and surface stability at temperatures up to 80% of their melting point. This so-called superalloys based on Nickel, iron or cobalt. Preferably superslab for the heating elements 43 includes at least 1% of aluminum to improve resistance to oxidation. This material produces firm "Haines of internasal", Kokomo, Indiana, under the name "Haines-214". This alloy contains, among other items, about 75 wt.% Nickel, 16% chromium, 4.5% aluminum, 3% iron. As noted above, the individual heating elements of the heating unit 43 89 include prints 131, containing many overlapping curved, essentially S-shaped, plots for increasing the effective resistance of each element. Because the prints 131 made of serpentine, shopline elements 43 with an impedance of 0.5 to 3, Ohms and a length of a fingerprint corresponding to the length of the heating unit 39 (Fig. 3A) or 39A (Fig. 5), preferably have N overlapping S-shaped sections, where N is from 3 to 12, preferably from 6 to 10.
If the fingerprint of the heater 141 (Fig. 8) first cut out in the form of a wide section 125 (Fig. 7) having a width W1, a length L1 and thickness T, then the resistance from one end 125' to the opposite edge 125" wide area is expressed by the equation:
where P is the resistivity of the material. After running the imprint 131 resistance increases because the effective electrical length of the heating element 43 is larger and the cross-sectional area smaller. For example, after execution of the print in the heating element 43, the current flows through the element along the path P. the Effective electrical length of the path P is 9 to 10 W1 (with five full turns of print) as opposed to the original L1. The cross-sectional area decreases from W1T up W2T. According to the invention increase the electrical length and reduced cross-sectional area of increasing impedance element 43, which is directly proportional to the electrical length and inversely proportional to the square cross-section.
Thus,La to obtain the specified resistance of a given heating surface 3-25 mm2. This characteristic of the present invention provides at least three advantages.
First, when the resistance heating element 43 receives from a rectangular sheet, whereas when it was manufactured as a linear element would require a greater length of material. This allows the heating unit 39 and the lighter 25 more compact at lower costs.
Secondly, since the energy consumption of the heating element 43 to a predetermined temperature in still air is determined by the mass of the heating element, the performance of its serpentine saves energy, allowing you to achieve a specified resistance with less volume. For example, if the volume of the heating element 43 is reduced by half, so the same is reduced and weight. Since the energy consumption for the heating element 43 to a predetermined temperature is proportional to the mass and thermal conductivity of the element, reducing the volume by half reduces the power consumption to the same extent, and the heating element 43 is a less energy-intensive.
The third advantage of reducing the volume of the heating element 43 when the snake run is the reduction of time of the heating element. Because it generally propiamente 43 not only compact and less energy-intensive, but quickly heated to the desired temperature.
So, if you are running many bends in the heating elements 43 (for example, when a serpentine form element) resistance of the element increases, without increasing its length or decrease the square cross-section. Other configurations are possible heating element 43, also shown in Fig. 8, while respecting the principle of compactness and efficiency.
Imprint 131 is cut in the heating element 43 in any manner, preferably by a laser (preferably CO2-laser). Due to small sizes serpentine heating elements 43 (for example, the gap B in Fig. 8 is 0.1 - 0.25 mm) laser cutting is preferable to other methods. Because the laser concentrates the energy in small volumes, the process is flexible, quickly, accurately, and easily automated. Moreover, in the laser processing less and induced stresses in the material, and the degree of thermal lesions (i.e., oxidation) compared to other cutting methods, for example, spark. It is also possible electro discharge machining, precision stamping, chemical etching, as well as the usual stamping, although it is unattractive due to rapid die wear.
Laser COI is predpochtitelno the YAG laser grenade - AIG). For example, heating the node 89 and pin block 91 are connected by spot welding with CO2or YAG laser. Rear ends 101 or ears 129 heating elements 43 are welded by laser to the electrical lead pins 104 in the support 50, or to the corresponding elements of the control circuit, or nests. To connect the elements lighters can be used by other known methods.
The invention allows to minimize dangerous stresses in the heating elements 43 by heat treatment. As can be seen in Fig. 6, the rear ends 101 (or ears 129), welded to the pins 104 or another electrical circuit or component, and lots of prints 131, produce heat, made in a single piece 43, eliminating the need to weld separate sections. Such welding would cause unwanted distortion during heating of the heating elements. The longitudinal axis of the end sections 101 or lugs 129 and parcel of prints 131 are the same as their misalignment also would cause distortion when heated. Further, the opposite ends 131' and 131" prints 131 is connected to netleverage sections of the heating element 43 in a symmetric manner, i.e. have the same direction. This symmetry the signets. Transitional areas 131' and 131" prints 131 to the adjacent sections of the heating element 43 and the edges are made with chamfers (Fig. 6) in order to reduce stress from heat.
The heating elements 43 and the heating unit 39 is additionally protected from hassles associated with repeated heating. Thus, when the heating elements 43 extend. Since the elements 43 are clamped between the fixed front end 135 of the pin block 91, attached to the front portion 121 of the heating unit 89, and a ring 99 at the rear end 101 of the heating elements, when the extension they can bend to either side of the cigarette 23 that it is desirable, or in the opposite direction, which is undesirable. In the latter case, there is a thermal gap between the heating element 43 and a cigarette 23 and tobacco tape 57 is heated unevenly and insufficiently due to the multi-level contact between the surface of the heating element and a cigarette.
To the heating elements of the heating unit 43 89 not curved outwards, or at least part of them form the curved inwards (Fig. 3A). It provides grip and good thermal contact between the heating elements 43 and the cigarette 23. Come what m on a cylindrical mandrel (not shown), having the right bend. Preferably the elements 43 to impart bending under pressure (not shown), before forming the heating site 89 in the cylinder. If the heating element 43 is initially attached to the inside bend, expand when heated, it increases. Bending along the length of the imprint 131 is flat. Transitional areas 137' and 137" chamfer can be bent stronger than the subtle imprint 131. This will prevent stress concentration from thermal treatment in the most vulnerable areas of the heating elements 43.
Around the imprint 131 of the heating element 43 can be performed ring (not shown). It serves as a heat sink and forces the expanding when heated prints 131 of the heating elements 43 to bend inwards, in the direction of the cigarette 23.
In addition to the heating unit 89, the heating unit 39 (Fig. 3A) contains also the spacer 49 and the support 50. The spacer 49 (Fig. 10A-10C) has a cylindrical outer surface 97, which pressed the pins 91 and the heating elements 43, fastened by the ring 99. The spacer 49 also has a bottom wall 139 in the lower inner surface 81 which abuts the cigarette 23, which ensures its correct location relative to nagrevatelnyh. The bottom wall 139 has a plot 47' channel 47, is in communication with the sensor 45 puffs. The area 47' is a hole in the bottom wall 139 parallel to the axis of the spacer 49. The bottom wall 139 is executed also section 55' holes 55 for the photodetector 53. The first hole 143 passes from the outer surface 97 of the struts 49 to section 55 of the hole. The first hole 143 provides the necessary resistance to the draft with the first puff of a cigarette 23, creating an additional passage for the air from the area around the cigarette in the zone near the back of the filter 63. Since the tobacco belt 57 and wrapping paper 69 restrict the inflow of air into the cigarette 23, while the heating element 43 will not heat adjacent thereto zone cigarettes, hole 143 allows air to pass into the area near the heating unit 39 by the inverse filter 63 cigarette. Return filter 63 flows into the cigarette 23 is sufficient air to reduce the resistance to pull against the expected. At the same time, the inverse filter 63 must be sufficiently "tight", but skip the specified air at the first puff to flavored tobacco smoke, remaining in the cavity 79 after tightening, not went through the inverse filter in the lighter 25. After the first tightening is respectively the first drag of the cigarette 23, the air flow through the first hole 143 and the feedback filter becomes insignificant for puffs.
Bearing 50 (Fig. 11A-11C) has an essentially cylindrical shape and includes a bottom wall 151 and the pins 104, connected to the pins 95 and the heating elements 43 and held in the holes 107 in the bottom wall past the bottom of the outer surface 105 of support. Bearing 50 has a cylindrical outer surface 153 and a cylindrical inner wall 155, and the diameter of the inner wall of the larger outer diameter of the spacer 49 and is equal to the outer diameter of the ring 99. The spacer 49 is pressed to the support 50 by friction between the inner wall of the 169 air sleeve 87, the ring 99 and the outer surface 97 of the spacer. As will be discussed below, provides a means for mounting the air sleeve 87 to the support 50. The spacer and bearing 50 can knit and in other ways - glue, screws or tight fit. On the support and the spacer can be made of the protrusions and depressions (not shown) to maintain these elements at the desired angle relative to each other. The bottom wall 151 has a plot 47" channel 47 from the axis to the edge of the support 50. Part of the area 47 may be made in the form of grooves on the lower inner surface 157 of the support, which is sealed after installation of the spacer 49. Plot 47" made in the form of intersecting longitudinal and radialis sections 47" and 55" supports 50, forming a channel 47 and the hole 55.
Element 49A of the heating unit 39A (Fig. 5) shown in Fig. 12A-12. Element 49A has a cylindrical outer surface 97A, to which ring 99 is attached pins 95 and the heating elements 43. Element 49A includes a bottom wall 139A, the lower inner surface 81A which rested the cigarette 23, due to which it is fixed relative to the heating elements 43 when installed in the lighter 25, and a cylindrical inner wall 141A for the passage of the cigarette. In the element 49A may be also made a hole for the first tightening (not shown). The bottom wall 139A there is a channel 47A provided with a sensor 45 puffs. Channel 47A is made in the form of holes passing through the bottom wall 139A parallel to the axis of the element 49A. In addition, the bottom wall 139A made the hole 55A to the photodetector 53. Through the lower outer surface 105A element 49A are rear ends 101 of the heating elements 43 and rear ends 103, at least two pins 95 to connect to the control circuit 41 and the power source 37. At the end of the element 49A performed flange 109, in which there are at least two groove 107 A and through which the rear ends 103 of the two pins 95 past the lower the outer on top is it the outer surface 105A radially outward over the edge of the flange 111. Air sleeve 87A planted around the edge 111 of the flange 109 to secure it in place of the rear ends 101 of the heating elements 43.
If not otherwise specified, then the Smoking system 21 is relative to the heating unit 39 shown in Fig. 3A-3B. However, it should be borne in mind that all of this applies equally to a variant of the heating unit 39A, shown in Fig. 5, and to other variants of the invention, are not here considered. The heating unit may include other devices capable of performing various functions, such as creating a space near the heating elements to heat the cigarette.
End view of the ring 99, which presses the heating elements 43 and the pins 95 to the outer surface 97 of the struts 49, shown in Fig. 13. The inner diameter of the ring 99 is sufficient to firmly press the heating elements 43 to the cylindrical outer surface 97. Along the inner circumference of the ring 99 90operformed a longitudinal slot 159 for thicker pins 95 to firmly press the pins to the outer surface 97.
Air sleeve 87 is attached to one end 161 to the support 50, and the other end 163 to the cap 83. The first con is the end 163 of the air sleeve 87 has an outer protrusion 171, included in the groove 173 on the inner bezel 175 of the cap 83. Air sleeve 87A in an embodiment of the heating unit 39A in Fig. 5 differs from the sleeve 87 in Fig. 3 so that the first end 161A of the air sleeve 87A has an internal groove 165A, which includes an outer projection 167A on the edge of the flange 111 109 element 49A. The sections of the heating elements 43 near the rear ends 101 is placed between the mating projections and grooves on the element 49A and air sleeve 87. As will be shown below with respect to Fig. 17, if necessary, to increase the flow of air in the heating unit 39 can perform multiple holes along the length of the air sleeve 87 where the air is not blocked and is not sent along a complex path cap 83 or spacer 49 before you get to the cigarette 23.
The cap 83 of the heating unit 39 (Fig. 3A) and cap 83A of the heating unit 39A (Fig. 5) are identical, except that the inner wall 177 of the cap 83 is longer than the wall cap 177A 83A. The inner diameter of the inner wall 177 of the cap 83 does not exceed the outer diameter of the cigarette 23, and preferably slightly less, to compress a cigarette inserted in the lighter 25, and firmly hold it tight-fit. Elongated internal to the Cap 83A are a number of longitudinal holes 179A, passing from the rounded or chamfered front end 93A to the rear end 181A to ensure that the air in the cavity of the heating unit 39A for receiving the cigarette 23, between the cigarette and the air sleeve 87 so that the transverse (i.e., directed radially inward flow of air passed through the tobacco belt 57 by fingerprint 131 of the heating elements 43. As can be seen in Fig. 3A, in a preferred embodiment, the cap 83 of the heating unit 39 drilling 179 at the rear end 181 is wider than the front end 93 to facilitate traction. In another embodiment, instead of the longitudinal perforations on the inner wall of the cap is made of longitudinal grooves (not shown). In Fig. 14A-14 on the rear end 181A made annular groove 183A for the reception and support of a heat-resistant sleeve 85 (Fig. 15A-15B). Heat-resistant sleeve 85 is a tube having first and second ends 185 and 187, any of which is inserted into the groove 183A. The radius of the ring grooves 183A more of the radius of the holes 179A, which facilitates the inflow of air into the heating unit 39, when the smoker zatyagivaetsya cigarette 23.
The cap 83 (Fig. 3A) is obtained by casting or machine. Preferably it is molded as a single piece, for example, the cap 83A (Fig. 5). Engl is connected. Before insert the inner part 83 in the outer 83', on its outer surface make the groove, after which the Assembly forms a groove 183. Thereby eliminating the need to drill a groove 183 in the solid part.
Heat-resistant sleeve 85 is removed and replaced by the desire of the smoker (for example, after 30-60 cigarettes 23). Sleeve 85 protects the internal wall of the 169 air sleeve 87 of residual aerosol formed between the heating elements 43 and the air sleeve. This aerosol is deposited on the heat-resistant sleeve 85.
Heat-resistant sleeve 85 is made of heat-resistant paper or plastic and is replaced by a smoker after he will smoke a certain amount of cigarettes 23. Thus in contrast to the design of the "tube in tube" aerosol barrier to block aromatization, which is thrown away after each cigarette, the heat-resistant sleeve 85 is designed for longer use. Accordingly simplifies the manufacture of the cigarette 23 and decreases the amount emitted after Smoking each cigarette material.
In Fig. 16 schematically shows the path of air flow in the heating unit 39 and the cigarette 23, when the smoker pulls the data channels 179 inside the heating unit 39 between the air sleeve or heat-resistant sleeve (not shown here), by heating elements (not shown) before contact with the cigarette 23, then through the permeable wrapping paper 69 and tobacco tape 57 (or holes) into the cavity 79 of the cigarette. From the cavity 79 of the air flows into the longitudinal channel 67 in the first direct filter 65, the longitudinal channel 77 in the second direct filter 73 and through the double filter 71 into the smoker. The number and diameter of the channels 179 chosen to optimize the flow total suspended solids (SS) to the smoker. In a preferred embodiment, the cap 83 is performed six to eight channels 179.
As can be seen from Fig. 17, instead of or in addition to the channels 179 provided by other passages for the air inside the heating unit 39 and the cavity 79 of the cigarette 23. For example, in the heating unit 39 in any place, usually in an air sleeve, you can drill one or more radial holes 189. Through the support and thrust it is possible to conduct a longitudinal channels 191. Channels 179 in the cap 83 may be in the form of holes or longitudinal grooves in the inner wall 177 of the cap. If necessary, reverse the filter 63 provides a longitudinal flow of air into the cavity 79, when the smoker puffs on his cigarette.
When neo is tra 63 cigarette 23. The handset comes to the cavity 79 and provides direct air access to it when tightening. At the working end of the tube has one or more holes, mostly on the sides of it that supply air flows with high velocity to create turbulence in the cavity. Such turbulence improve the mixing of incoming air with the aerosol and vapors from the cigarette 23.
The electrical circuit 41 controls Smoking system 21 is shown in Fig. 18. It includes a logic circuit 195 and applied integrated circuit (ASIC), a sensor 45 puffs, signaling that the smoker puffs on his cigarette 23, the photodetector 53, signaling that the cigarette is inserted in the lighter 25, the liquid crystal display 51 of the remaining number of puffs, the source 37 of energy and circuit 197 synchronization. The logic circuit 195 may be any conventional circuit capable of performing the indicated functions. User-programmable logic matrix (for example, type ACTEL A1010A FPGAPL44C company AkTel. Sunnyvale, Calif.) can be programmed to perform the functions of digital logic, so that the analog functions are implemented by other elements, whereas the scheme ASIC performs both analog and digital functions. The control circuit and loprazolam embodiment of the invention eight heating elements 43 (Fig. 18 not shown) is connected to the positive power source 37 and grounded through the respective switches 201-208 on field-effect transistors. These switches 201-208 displayed on logic 195 via terminals 211-218. Logic circuit 195 generates signals on separate switches 201-208, including turning off the corresponding heaters.
The sensor 45 outputs a signal to the logic circuit 195 that the smoker is delayed (on the basis of continuous differential pressure or flow for a sufficient time). Logic circuit 195 includes a filter element that distinguishes small pressure fluctuations and deep tightness to prevent false activation of the heaters from a random signal of the sensor 45. The sensor 45 may include a piezosensor pressure or optical sensor shift, resulting in the action of the operational amplifier, which outputs a signal to the logic circuit 195. This system is suitable silicon sensor model RS branch Microswitch" company "Honeywell, Freeport, Illinois, or type NPH-5-02.5 GNOVA company "Lucas Nova, Fremont, California or type SLP004D firm "Sezim", Sunnyvale, California.
When the inserted cigarette 23 in the lighter 25 to the desired depth (in several aetsa reflected light beam) detector 53 outputs a signal to the logic circuit 195. This may be a photodetector type OPR5005 firm "Optek technology", Carrolton, Texas. To save energy, it is preferable that the sensors 45 and 53 used in the minimum cycle (less than about 50, or 20% of the set period of time, or from 2 to 10% of the time, or less than about 5% of the set period of time). For example, the sensor 45 must be switched on for 1 millisecond every 10 milliseconds. If the sensor 45 detects the differential pressure from tightening the four pulse in a row (i.e. for 40 milliseconds), it sends a signal through terminal 221 to a logic circuit 195, and that, in turn, through the corresponding terminal 211-218 on the switch 201-208 need a heater.
The photodetector 53 is also included for 1 millisecond every 10 milliseconds. If he finds four of the reflected pulse in a row, which indicates the presence of a cigarette 23 in the lighter 25, it sends a signal through terminal 223 to a logic circuit 195. Scheme 195 outputs via terminal 225 a switch-on signal of the sensor 45 and terminal 227 is to switch on the indicator 51. This reduces the current consumption of the sensors 45 and 53 and extends the life of power source 37.
The timing circuit 197 is a timer with a constant flow of energy and produces a signal which can be found in the action switch 201-208, he worked for a specified time. This time is determined by the voltage on the power supply, which decreases as they age. Scheme 197 also does not allow the inclusion of one of the heating element 43 immediately after the previous one when a discharged battery. There may be other design scheme synchronization, as shown below.
When the cigarette 23 is inserted in the lighter 25, the photo detector 53 detects its presence. The photodetector sends a signal via terminal 223 to a logic circuit 195. Scheme 195 checks if there is enough voltage in the source 37. If impact that energy source 37 low voltage, the indicator 51 blinks, and the lighter will not operate before recharging or replacement of the energy source. The voltage of the power source 37 is controlled during ignition of the heating elements 43, which terminates if the voltage drops below a certain level.
If the energy source 37 is charged and the voltage is sufficient, the logic circuit 195 sends a signal via terminal 225 to the sensor 45 to find out is delayed if the smoker of the cigarette 23. At the same time via terminal 227 a signal to the indicator 51, and it lights up the figure "8", indicating a possible eight puffs.
is to be placed, it disables the photodetector 53 at the time of tightening the purpose of saving energy. Terminal 231 is fed to a timing scheme 197 on the inclusion of the timer. Logic circuit 195 also determines by countdown, which of the eight heating elements to be heated, and sends a signal through the corresponding terminal 211-218 about the response of the desired switch 201-208. Need the heater turns on and the timer counts the time.
When the circuit 197 synchronization reports via terminal 229 to a logic circuit 195 that time has expired, the switch 201-208 is turned off and the power supply for this heating element is terminated. Logic circuit 195 produces a countdown and outputs via terminal 227 indication on the indicator 51 to show that remained on one inhaling less (i.e. "7" after the first tightening). If following tightening logic circuit 196 includes the following switches 201-208, thereby feeding energy to the other heating element. The cycle repeats until the indicator 51 will not show "0", i.e., puffs on a cigarette 23 left. After removal of the cigarette 23 in the lighter 25, the photodetector 53 shows her absence, and the logic circuit 195 is reset.
In the control circuit 41 can is okidoki, for example, the timing circuit (not shown) which prevents too frequent puffs to the energy source 37 had time to recover, or means for locking the heating elements 43, if the heating unit 39 is inserted a foreign object. The cigarette 23 is possible to give some indication to the lighter 25 can identify it before it is submitted energy to the heating elements 43.
Another option Smoking system 222 in accordance with the present invention shown in Fig. 19. A Smoking system 222 includes disposable cigarette 224 and the lighter 226 reusable, into the opening 228 which is inserted cigarette. In the Smoking-room system 222 adopted "thirst center", i.e. the air flow is essentially goes along the axis of the cigarette 224 and lighters. Lighter 226 contains a power source (not shown) at the opposite hole 228 end and a control circuit (not shown). Like the system 21, a Smoking system 222 preferably includes a sensor puffs and indicator (not shown).
Lighter 226 is placed in the housing 232 having the appearance of an ordinary cigarette. The housing 232 is made in the form of a tube of heat-resistant plastic or aluminum, or formed in the shape of a spiral of the double layer is uranie. You can make channels for air (not shown) in the cigarette 224 or in other places lighters 226.
Cigarette 224 is identical to the cigarette 23. Cigarette 224 includes tobacco ribbon 257, performed on the media 259, serves as a support for a fragrant material 261, preferably tobacco. The tobacco ribbon 257 wrapped around a cylindrical reverse filter 263 at one end and a cylindrical first direct filter 265 from the other end. In the first direct filter 265 may be made of a longitudinal channel (not shown).

First direct filter 265, inverse filter 263 and double filter 271 is connected by any method suitable in the conditions of mass production.
Unlike cigarettes 23, cigarette 224 includes an annular aerosol barrier 273, surrounding a specified range of tobacco ribbon 257. Aerosol barrier 273 minimizes Conde which can be attached to the cigarette 224 around the first direct filter 263 clamp 275. The clamp 275 and aerosol barrier 273 possess sufficient rigidity to prevent breakage cigarettes 224 and to maintain the alignment between the barrier and the outer surface of the tobacco belt 257, maintaining between them a uniform gap. Wrapping paper 269 binds double filter 271, the first direct filter 265, the clamp 275 and the edge of aerosol barrier 273.

Elements 243 preferably have a linear shape and are from a point inside lighters 226 near the holes 228 to a point near the cavity 245, in which is inserted an inverse filter 263. Heating elements 243 are connected together on the end facing the cavity 245 of the inverse filter, and with their ends facing the hole 228, the face is removed, thanks to which the inserted cigarette 224 does not damage the heating elements. Heating elements 243 are in the gap between the tobacco ribbon 257 and aerosol barrier 273.
The heating unit 239 is shown schematically in Fig. 20. It includes support 249 heater, a support 251 and a few supporting legs 253 made of heat-resistant electrically conductive material. Prov.and ends 243', 243 using conductive fingers 255A and 255B.
Cavity to remove cigarette forms a ring, and a set of supporting fingers of the heating unit moves away from the first end of the prop heater and to provide support to the many regular heaters. The fingers are made oblong, have an inner and outer surface and placed so that they form the surface of the cylinder, where the constants heaters placed on the outer surface of the support fingers.
The ends 243' heaters 243 are electrically connected, forming a "common point" heating system. Bus 291 is connected to the conductive plate 293 connected to the conductive fingers 255A, which are connected to the ends 243' heaters 243.

The clamp 297 heater includes 299 neck covering part of the tire 291 near conductive plate 293. The neck 299 has one or more channels 301 to supply air into the channels 295. Conductive pins 303 pass through the clamp 297, providing electrical connection fingers 255B diagram 241 management. Fingers 255B are along the outer edges law 255B curved, to provide a seal clamp 297 and cervical 299, through which the ends 255B' come into contact with the pins 303. This design facilitates the attention of the heating elements 243 of lighters 226 for replacement or repair. Pins 303 and bus 191 are inserted into slots (not shown) for connecting the heating elements 243 schema 241 with the aim of switching the heating elements.
Device 321 for the manufacture of parts 224' cigarette 224, including tobacco ribbon 257, first direct filter 265 and the feedback filter 263, shown in Fig. 21. Material 259' for media 259 is drawn from a roll 323 measuring rollers (not shown). Tape 259' media includes lots of flavored tobacco material 261, which are applied to the tape 259' of the carrier at station 325 or anywhere, for example, before unwinding roll 323. Tape 259' then passes the station 327, where its surface is coated with glue at several sites 261A. Or you can put flavored tobacco material 261 tape 259' continuously, and apply glue on the section 261A on top of the tobacco material.
For station 327 adhesive application station 329 attaching filters. It includes the drum 331, which alternately attach filters 333 Il is part of the supply tape 259' of the media.
For station 329 attaching the filter station is 337 swivels. Tape 259' media wrap around filters 333 and 335 with getting a solid rod. The resulting rod is cut off at the station 339. Station 339 includes a means for cutting the rods to the middle of the filters 33 and 335 so that the cut sections of the filter 333 is formed by two first direct filter 265, and cut off the parts of the filter 335 is formed by two inverse filter 263 two portions 224', from which to make cigarettes 224. After cutting through the inverse filters 263 can be processed by bending them so as to facilitate the placement of the heating elements around 243 segments 224'. After cutting each piece 224' insert into aerosol barrier 273 on the corresponding station (not shown) and attach the clamp 275. The diameter of the barrier 273 larger than the diameter of the continuous rod and the length of at least the same as the cut cigarettes 224. To each direct filter 265 is attached a cylindrical double filter 271 and each aerosol barrier 273 with the corresponding mouthpiece filter 271 is wrapped in a wrapping material at the respective stations (not shown).
Another version of the Smoking-room system 421 shown in Fig. 22. This system on the part of the circular plot cigarettes 423.
Cigarette 423 includes tobacco ribbon 457, in which flavored tobacco material 461 placed on the surface of the carrier 459 opposite cavity 427. Cigarette 423 also includes aerosol barrier 473, tube 475, ring direct filter 465, ring return filter 463 and double filter 471. Direct filter 465, inverse filter 463, tobacco 457 tape and aerosol barrier 473 form a cavity 479, in which when heated flavored tobacco material heaters 461 443 is formed flavored smoke. Cigarette 423 surrounded by wrapping paper 469. The heating unit 439 supplied with a plug 477, which together with tube 475 minimizes the migration of the aerosol through the heating parts of the system 421. In traffic 477 is a through hole wire 481, in which heating elements 443.
In Fig. 23 shows a variant of the electrical system 541 management. System 541 performs several functions. It sets the control sequence of the eight heating elements 43, choosing one of them at each actuation of the sensor 45 puffs. It supplies current to the selected heater within a specified period of time required for the l 61 began to burn. The system manages the indicator 51, which shows (1) how many puffs in the cigarette 23; (2) whether there is enough voltage in the power source 37; (3) is inserted if the cigarette into the lighter 25; (4) inserted into the lighter 226 heater unit 239.
Select one of the many electric heaters can be operated manually by the smoker, or automatically by the control system.
System 541 also controls the amount of energy supplied by the source 37 at each heating element 43. Because the voltage supplied by the source 37 may vary with each puff, it is preferable not to vary the amount of energy, each including a heating element 43 at the same time, and to apply an equal amount of energy at each puff. For this scheme 541 controls the load voltage source 37 when the heating element 43 and continues the flow of energy until the specified number of joules.
As can be seen from Fig. 23, the circuit 541 includes a logic circuit 570, a binary-decimal decoder 580, the detector 590 voltage circuit 591 synchronization, the sensor 45 puffs, the indicator 51 and the charging circuit 593. Logic 570 may be lubale logical matrix (type ACTEL AI0I0A FPGAPL44C firm "Actel Corporation, Sunnyvale, California). Preferably the logic circuitry 570 is working with a small step (for example, 33 kHz) to conserve energy.
Each heating element 43A-43H connected to the pole of the energy source 37 and grounded via a corresponding field-effect transistor 595A-595H. Transistors 595A-595H included running a binary-decimal decoder 580 (standard 4-16-line decoder type C 4514B), via terminals 581-588, respectively. The decoder 580 receives from the logic circuit 570 via the control input 580A two types of signals: (1) BCD code to be turning on the heater 43A-43H; (2) the signal on and off for this heater.
The decoder 580 is connected via terminal 580B to enter 593A paradoksy circuit 593, which applies a voltage to the gates of each of the field-effect transistors 595A-595H. The charging circuit 593 includes a diode 594 connected to the power source 37, and a capacitor 595 connected to the logic circuit 570. The logic circuit 570 includes a conventional switching circuit (not shown) connected to terminal 572, which allows the voltage at terminal 593B charging circuit 593 to grow to twice the size than the source 37. Thus, the doubled voltage at terminal 580B decoder 580 opens the gates Tr is s resistors 596A-596H, prolonging the time of loading of the respective valves to minimize high-frequency harmonics that create noise in the control circuit 541.
The sensor 45 outputs a logic circuit 570 a signal of tightening smoker (at a pressure drop of about 25 ml of water column). The sensor 45 may include a piezosensor pressure, resulting in the action of the operational amplifier, the output of which is as logical is input to logic circuit 570. It may be a pressure sensor type NPH-5,0256-NOVA company "Lucas Nova, Fremont, California, or type SLP004D firm "Sensim", Sunnyvale, California.
To save energy, sensor 45 operates at low stage (2-10% of the time). Preferably it is included on every 0.5 MS 16 MS. This reduces the energy consumption of the sensor 45 and thereby extends the service life of the power source 37.
Scheme 591 synchronization issues a trip signal to the logic circuit 570 after the heater 43A-43H worked for a specified time determined by the supply of the necessary amount of energy. It is preferable to use each heater 43A-43H at this time that he received the same amount of energy (from 5 to 40 j, optimally 15-25 j), regardless of naprashivalos is considered to be constant (for example, 1, 2 Ohms). Terminal 59IB then sends a switch-off signal at terminal 578 logic circuit 570 indicating the time needed to supply a given amount of energy.
The preferred embodiment of the circuit 591 synchronization shown in Fig. 24. Scheme 591 includes input 591A, which receives from the logic circuit 570 signal, which changes the voltage from zero to the load at initial turn on one of the heaters 43A-43H. This signal is filtered through a capacitive-resistive circuit 601 (includes resistors 603-606, the capacitor 607 and the diode 608) and is fed to the detector 602 overvoltage. The detector 602 type ICL7665A manufactured by a company Maxim, Sunnyvale, California. Capacitive-resistive circuit 601 is selected so that the terminal 591B scheme 591 changes the state from "high" to "low" when the heater comes preset amount of energy. Of course, the synchronization can be performed otherwise.
Scheme 541 can set the time limit for the filing of a given amount of energy. For example, if the voltage source 37 is low, the supply of 20 j of energy will take more than 2c, circuit 570 outputs at terminal 571 shut-off signal after 2c from the heater, although success is t switch-off signal to a logic circuit 570 after a certain period of time, regardless of the number of submitted energy. So, the scheme 591 generates a switch-off signal when the expires time in the range of 0.5 to 5.0 c.
The voltage detector 590 controls the voltage source 37 and outputs a signal at logic 570, when the voltage (1) below the first predetermined threshold (for example, a 3.2 B), which means the need to recharge, (2) greater than the specified threshold (for example, 5, 5B), which suggests that the source is fully recharged after the voltage has fallen below the first threshold. Preferably this voltage detector type ICL7665A firm Maxim, Sunnyvale, California.
As noted above, the logic circuitry 570 controls the binary-decimal decoder 580 via terminal 571. The logic circuitry 570 also manages the indicator 51, which shows the remaining number of puffs and constitutes a clear seven-segment liquid crystal display system, designed for eight puffs. So when the cigarette is inserted and contains all eight servings of tobacco, the indicator 51 shows "8", and when there was only one portion is "1". After using up the last of the torque indicator shows "0".
In addition, the indicator 51 shows "0" when not Vica energy fell below the betrayed recharge (3,2 B) or not fully recovered when recharging, the led flashes with a frequency of 0.5 Hz. For example, if, immediately after the first tightening voltage has fallen below 3, 2B, "7" on the indicator 51 appears on and off twice per second.
The logic circuitry 570 via terminals 597A and 598A determines inserted into the lighter heating unit, measuring the voltage drop across the high resistance resistors 597 and 598 (e.g., 1 Mω). One of the conclusions of each of the resistors 597 and 598 are constantly connected to the drains of MOSFETs 595 and 595H, the other grounded. When the heating unit is not inserted in the lighter, heaters, identified as 43G and 43H in Fig. 23, disconnected from the drains of transistors 595G and 595H. Accordingly, the power source 37 is disconnected from these drains. As a result, the voltage does not appear on the resistors 597 and 598 are controlled by a logic circuit 570 via terminals 597A and 598A. Hence, in the absence of the heating unit in the lighter logic circuit 570 detects zeros on terminals 597A and 598A.
When the heating unit is inserted in a cigarette lighter, the power source 37 is connected to the resistors 597 and 598 through heaters 43G and 43H. As a result, the resistors 597 and 598 receive a voltage, and the logic circuitry 570 detects units at terminals 597A and 598A. The logic circuitry 570 controls two resistenti resistor 597 and 598 short circuit to earth. As a result, if you were to use only one resistor, there would be a false indication of no load on the heating unit. However, in the case of two resistors, turning on the transistor 595G the voltage across the resistor 597 will be close to zero, and the resistor 598 shows a logical unit, and Vice versa. So there are two resistor 597, 598 and signals with resistors 597 and 598 fall under the logical OR circuit 570 to determine the load in the heating unit.
To install, you have installed a cigarette lighter, logic circuit 570 includes an additional terminal 599, which receives the signal of the presence of cigarettes. The signal at terminal 599 is produced in the usual switch 599A, which is mechanically and electrically activated by the presence of cigarettes. However, if the cigarette contains a Mat of carbon fibers, the signal on terminal 599 is created when the electrical connection of the probe to the Mat to check the currents flowing through it. Because the carbon Mat is not isolated, it comes in contact with the heater connected to the power source 37 (Fig. 23), leak currents in the Mat regardless of the enable transistors 595A-595H. Such leakage currents are controlled by the probe connected, which showcases the lighter on conductive carbon Mat, conductivity can also install a specific type of cigarette (for example, type X in contrast to type Y). In accordance with the sign of the logic circuit 570 determines the resistivity of the carbon Mat with two additional terminals (not shown) coming into contact with the Mat at different points. Because each brand of cigarettes corresponds carbon Mat with a specific resistivity in a certain interval (depending on the kind and quantity of fibers and/or binder), the measurement of specific resistance allows you to set what type of cigarette is inserted into the lighter. This allows the logic circuit 570 to elaborate a programme of energy supply.
For example, the first brand of cigarettes includes carbon mats with one value of the specific resistance of the second grade. If the logic circuitry 570 is able to distinguish them in place, then the measurement results it regulates the power supply for the heaters.
In this case, the mode power supply varies in accordance with the type of the cigarette is inserted into the lighter. For example, after the logic circuitry 570 will measure the resistivity of this cigarette, it will be to supply power to parti is considerable resistance brand of cigarettes, on the lighter is not calculated.
As can be seen in Fig. 23, before the smoker takes the first puff, the indicator 51 appears "8", which means that eight puffs. Accordingly, logic circuit 570 generates the address of the first heater (e.g., 43A) to terminal 571, and the decoder 580 selects the heater (via terminal 581) to enable on-demand smoker. When a smoker makes the puff sensor 45 sends a signal to the high state via terminal 575 logical circuit 570, which indicates the pressure drop in the cigarette lighter of not less than 25 mm of water column. The logic circuitry 570 sends a signal via terminal 571 decoder 580 about enabling transistor 595A the first heater. Then the voltage from terminal 580B decoder 580 is supplied to the gate of the first transistor 595A, which includes your heater.
Simultaneously with the start of the first heater 43A scheme 591 synchronization monitors the amount of power fed to the heater, and sends a logic signal circuit 570 via terminal 57B at the time, when reaching a specified amount of energy, for example, 20 j. Then the scheme 570 sends a signal via terminal 571 decoder 580 about disabling the heater 43A.
In anticipation of the second tightening logical the tightening was included in the second transistor 595B, and the indicator 51 orders show "7" to the smoker saw that there were seven puffs.
In a logic circuit 570 can be embedded synchronization unit, so as not to give the smoker the opportunity to make a further tightening, until you restore the energy source. Such unit (not shown) may block the signal on the decoder 580 via terminal 571 within 6 s after the previous signal off. The indicator may blink with a frequency of, for example, 4 Hz, showing the smoker that lighter blocked (on a different frequency than the one that shows the voltage drop).
Regardless of whether these locks with a second puff (after blocking time, if it is provided) scheme 541 control repeats the above cycle.
Then it repeats until you employed the last heater. At this time, the logic circuitry 570 (1) orders the indicator 51 to give an empty indication and (2) blocks to include all heaters, while in the lighter does not insert a new cigarette.
Although in Fig. 23 in the circuit 541 of the control logic circuit 570, a binary-decimal decoder 580, the voltage detector 590 and scheme 591 synchronization are shown as separate blocks,I cigarette may contain a tool showing the smoker, it was inserted into the lighter and removed from it. For example, unused cigarette can be a sticker, you need to break before you insert it into the lighter. If the cigarette has already been used, it will not have such a sticker. Either the cigarette has a plot that is torn, broken, squeezed or otherwise deformed when inserted into the lighter.
Disposable cigarette can contain a vehicle, showing the smoker that she was subjected to heating. It may contain heat-sensitive portion which when heated changes color. Either on this site may be fusible strip, etc. There are many ways to show that the cigarette is subjected to thermal heating. Moreover, there are also electrical and mechanical means.
