Title: Analytical testing system and method for vaping devices

Description:
FIELD OF INVENTION 
     The present invention relates generally to the field of analyzing, testing and measuring parameters of smoking products that may be inhaled by a person, and corresponding vaping devices. It relates more particularly to an analytical testing system and method adapted to analyze at least one vaping device. 
     BRIEF DESCRIPTION OF THE INVENTION 
     The known vaping devices work by heating and vaporizing liquid which is then inhaled by the user. Vaping devices, also known as Electronic Nicotine Delivery Systems (ENDS), electronic cigarettes or e-cigarettes were developed as an alternative to tobacco cigarettes. Vaping devices typically comprise a mouthpiece, a tank, an atomizer, a control unit, a battery and a control panel. The liquid to be vaporized (the “e-liquid” or “e-juice”) is contained in the tank. The tank may be replaceable or refillable. During using a vaping device, the heating element atomises the e-liquid to create an aerosolized vapor which is inhaled by the user. 
     The efficiency and quality of operation of the vaping devices are significantly dependent on such parameters as: vapor and environment temperature, pressure drops, presence of harmful impurities, the vaping device air channels defects, type of e-liquid etc. Good balance of the mentioned parameters list allows an efficient and stable operation of the vaping device and must be ensured during the development and manufacturing of such vaping devices. Any device of a production lot must comply with the standards and guarantee stability of a vaping device. 
     The stability of a vaping device, according to the claimed invention, is the ability of a vaping device to provide an operation parameter mentioned by the manufacturer, such as specified evaporation rates throughout each vaping device operation session during the life cycle. 
     Most manufacturers provide vaping devices testing methods, technologies and systems which allow to determine the proper quality of their products. 
     The vaping devices based on e-liquid evaporation have become widespread. The new technologies are able to implement new testing systems for studying parameters of electronic cigarettes, for example, the CETI8 system from Cerulean. The term “CETI” is an acronym for “Cerulean e-Cigarette Testing Instrument”. This system allows an operator to select the shape, volume and duration of puffs of the diffused product, as well as the number of puffs and pauses between them for capturing vapors at a buffer-filter for an off-line chemical analysis. 
     The known test systems are becoming popular and are on the stage of technology development. The main directions of development comprise improvements of mobility, automation, measurement accuracy, expanding the range of applications. The present invention allows to improve ergonomics, in particular, simplicity and ease of use, as well as versatility for any needs of manufacturers, suppliers and distributors. 
     Timely identified defects of a vaping device allow to eliminate risks associated with the use of a faulty or a low-quality vaping device, in particular, may become harmful to the users&#39; health. 
     The patent GB2588113A (Cole Akinwande, priority date 10 Jul. 2019) studies the apparatus and method for testing a tobacco heating product. The apparatus comprises: means for puffing the product; means for sensing the temperature of gas downstream of the product; and means for generating a status signal indicating the heating status of the product in dependence on the sensed temperature. 
     The apparatus may also remove particles from the aerosol drawn from the product and/or capture particles for further analysis. 
     The means for sensing temperature (i.e. thermocouple sensor, thermistor, resistance thermometer, silicon bandgap/optical/solid-state temperature sensor) may produce a temperature signal depending on the difference between the temperature of the gas stream and ambient temperature, wherein said temperature signal is compared to a threshold value. The control unit may cease or modify puffing the product  1 , and/or may output an alarm, in dependence on the status signal. The product  1  may comprise a tobacco heated stick heated by an external electrical heating system, an internal electrical heating system, a sustainably self-heating tip (i.e. carbon tip), or by means of a chemical reaction. 
     Also a testing apparatus with dry wick indicator and a method of indicating the dry wick condition in a vaping device is known from the prior art (a patent GB2571999A, Francis Tindall Ian, priority date 16 Mar. 2018). The dry wick indicator for a vaping device comprises a detecting means for detecting a decomposition product from a vaping device, and means for producing a signal indicating dry wick condition based on an output of the detecting means. The indicator may further comprise a discriminator for comparing an output of the detector with a reference, wherein the signal is output based on the result of the comparison. The decomposition product may be formed by pyrolysis, thermal degradation or combustion of e-liquid base, may not be present in the e-liquid from which vapor is produced, and may be selected from carbon monoxide, carbon dioxide, formaldehyde, acetone, acrolein and/or acetaldehyde. The detecting means may use non-dispersive infrared spectroscopy. Fourier transform infrared spectroscopy, colorimetric analysis and/or reversible oxidation, and/or may comprise an electromechanical cell having a working electrode, a reference electrode and a counter electrode in contact with an electrolyte. Detecting means using a detection technique selected from at least one of: nondispersive infrared spectroscopy; Fourier Transform infrared spectroscopy; colorimetric analysis; and reversible oxidation. The detecting means comprises an electrochemical cell. 
     The closest technical solution to the present invention is described in the patent EP2959783B1 (Daniel Eclache, priority date 23 Jun. 2014). The machine for analyzing at least one diffusion device for a product capable of being aspirated, respirated, or inhaled by a user of the diffusion device and/or for analyzing a product diffused by such a diffusion device, comprises: an automatic control device, 
     an inlet compartment with a controlled atmosphere, at least one actuator attached to the diffusion device and controlled by the automatic control device, at least one element for regulating the temperature and/or the humidity of the atmosphere in the inlet compartment, at least one element for regulating the pressure, temperature, and/or humidity in the outlet compartment, at least one ventilation element connected to the diffusion device being controlled by the automatic control device in such a way as to produce ventilation with predetermined characteristics, at least one analysis hardware element allowing for the analysis of a flow diffused by the diffusion device. 
     The analysis hardware comprises an element for taking samples of the flow for a physical-chemical analysis of the product diffused by the diffusion device and returned to the outlet compartment. 
     The described technical solutions and methods which are known from the prior art, substantially present testing equipment for laboratories. Such equipment needs special additional supporting frame structures, ventilated compartments, with constant operating conditions for better measurements accuracy. Also such laboratory equipment is designed as a non-mobile and single-purpose machine which may be difficult to operate. 
     Also obtained test results do not allow to assess the stability of vaping devices in the real time, since measurement of individual parameters allows to make decisions only on the basis of all tests. At the same time, for example, changes of any parameter do not allow fixing changes in the operation of the entire system during a single test at each point of time. 
     Unfortunately, these prior art design present numerous disadvantages. There is always a need for an improved device that is easy to assemble/disassemble and manufacture.

Indicating conformity/non-conformity (with objective value according to the vaping device technical characteristics and test program). At this stage, the vapor flow state signal parameters dynamic changing is compared with the data from the database  408  and the result is put out through the  411  visualization unit. The real-time changes are shown in graphic form ( FIG.  8   ). If the vapor flow state is within the normal range, in the result of the entire testing program cycle, it indicates the stability of a vaping device is in conformity. After that the vaping device testing program may be terminated. 
     According to the present embodiment, the vapor flow state signal is substantially based on the vapor flow density parameter fixed within the vapor channel ( 203 ). Wherein the vapor flow density dynamic parameter is based on at least the vapor flow reflected light signal related to the weight of the vaping device, the product type, the dimension dependence parameters of the measuring unit ( 101 ) components. Each testing program may have a vapor density limit which must be set, for example as 3000-5000 units. This setting performs an automatic stop of the vaping device test if the vapor amount becomes low during the test (device discharged or liquid tank empty indication). 
     Referring to  FIG.  7    the vaping device stability determination substantially, includes all the steps of the vapor flow state determination ( FIG.  6   ), after which the following steps are comprised: e) Forming a degree of non-conformity. If non-conformity was detected in step (d); f) Comparing and analyzing an interdependence of the MU sensor set parameters depending on dynamic changing of at least one of the flow state parameters fixed within the vapor channel ( 203 ), such as the vapor flow density dynamic parameters; g) Forming the reason for non-conformity. 
     Using dynamic changing of at least one of the flow state parameters as a marker of the real-time instability of a vaping device. Based on the real-time vapor flow state signal value comparing and analyzing the interdependence of the MU sensor set  207 ;  208 ;  209  parameters and detecting the stability parameters of a vaping device. Forming the vaping device testing report, and providing the real-time stability parameters of a vaping device with a task or a tip for optimization of the stability of a vaping device. 
     Examples of monitoring the flow state parameters as part of evaluating the real-time stability of a vaping device: “liquid tank is empty”—the operation circuit (units  402 ;  403 ) fixing a dynamic decrease of the vapor flow density within the level indicates an absence of a product in the vapor flow, while the system takes into account an additional parameter, for example, the harmful impurities sensor  209 , such as CO (carbon monoxide) sensor and forming a report on non-conformity of the stability of a vaping device, with the possibility of determining causes; “Pressure drop”—the operation circuit (units  402 ;  403 ) fixes a dynamic decrease of the vapor flow density within the level indicating pressure drop. In this case as an additional parameter the pressure drop sensor data may be used; “High temperature”—the operation circuit (units  402 ;  403 ) fixing a dynamic increase of the vapor flow density within the level indicates an excessive heating temperature of the product by the vaping device. 
     Each example using the units  406  and  407  to compare and analyze the interdependence of the MU sensor set parameters and detect the stability parameters of a vaping device depending on the data of the required sensors. Possible embodiments of the invention allow to monitoring the product weight parameters and the vapor flow composition based on at least the vapor flow reflected light signal using a combination of different wavelengths in a visible and/or a non-visible spectrum. 
     The above examples are not limited and may have corresponding indicators displayed by the users&#39; devices  107 ,  108  or shown on the display of the main module  300 . A list of parameters influencing the stability of a vaping device according to the vapor flow density changes flow can be expanded by experimental, mathematical modeling and other ways. A variety of tests, as well as calculated results, can be used to train the analytical system to respond with a higher accuracy according to vapor flow changes.
