BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates generally to a cleaning device, and more particularly to a brush cleaning device that can be used to clean and sanitize hairbrushes, combs and cosmetic brushes.
SUMMARY OF THE INVENTION
The instant invention is directed to a cleaning device that incorporates optimized physical brushing action, water agitation, submersion and/or solution directional features to clean brushes, and which cleans, flushes and sanitizes hairbrushes, combs and cosmetic brushes. In the preferred embodiment, the Archimedes Screw principle of moving both fluid and particles in a determined direction is employed to remove hair, scalp debris and oils from both hairbrushes and combs.
In general, the device comprises a tank, brush frame and brush assembly, a motor housing and a top cover. The tank may have a substantially flat bottom and upraised sidewalls defining an interior or central space communicating with an open or partially open top, and is configured to contain water or cleaning solution. The tank may be comprised of a transparent or translucent material to allow the operator to observe the cleaning process, or it may comprise an opaque material. The top cover preferably comprises an opening, plurality of openings or throat opening, in which one or a plurality of brushes, cosmetic brushes, combs or hairbrushes can be inserted so that the bristle portion of each brush or comb to be cleaned and/or sanitized is optimally oriented in the device for cleaning.
In the preferred embodiment, the cleaning brush and the hair remover have, respectively, a specialized bristle and prong, pattern. The cleaning brush in the preferred embodiment rotates and is arranged, so that bristle-to-bristle (or bristle-to-prong in the case of combs) contact between the cleaning brush and the brush, comb, or cosmetic brush to be cleaned or sanitized, is optimal. In one version of the preferred embodiment, at least one rotating brush preferably comprises a bristle portion configured in a specialized densely packed pattern and/or a double radial spiral pattern about a support column, or “core”.
In the preferred embodiment, rotation may be imparted to the rotating brush or brushes by, for example, an electric or battery operated motor, which engages one or more gears communicating with the rotating brush or brushes.
In the preferred embodiment, a tank receives water or other cleaning liquid and rotating brushes, or a combination of rotating and stationary brushes, are configured so that thorough cleaning and movement of the cleaning fluid can be accomplished without the need for injecting or pressurizing the cleaning liquid.
The device is self-contained, portable and lightweight and achieves thorough cleaning and/or sanitizing of brushes or combs without the need for hose connections or plumbing systems and permits several brushes or combs to be cleaned simultaneously. Water agitation and specialized cleaning means or brushes having a specialized pattern of bristles permits any brush, comb, hairbrush or cosmetic brush to be thoroughly cleaned or sanitized within about a minute or less without shaking, damaging, bending or rotating the brushes or combs themselves. The device may be used to clean brushes and combs used with oil-based as well as water-based makeup or hair preparations.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed and/or utilized. The description sets forth the functions and the sequence of steps for operating the invention in connection with the illustrated embodiments. However, it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the invention. References to top/bottom, right/left etc. are relative terms provided for clarity and, unless otherwise noted, are interchangeable.
Referring to FIGS. 1-4 of the drawings, the device of the preferred embodiment generally comprises an upper portion 72 comprising a pair of openings 56(a), 56(b), a housing portion 74, a roller brush 76 and a hair remover 60 (FIGS. 2-4). In the preferred embodiment, the device 64 is configured so that the housing portion 74 (and preferably also the upper portion 72 so that the two portions are seated) is concave as shown in, by way of example only, FIGS. 1-2 and 4(b). The concave shape of the preferred embodiment, together with the movement of the roller brush 76, creates a “hydrodynamic swirl” or cyclone effect in the cleaning fluid forcing the cleaning fluid in a 360° motion around the item to be cleaned, further enhancing cleaning action. The first and second openings are preferably disposed on opposite sides of the roller brush and the device configured in a concave, or rounded crescent shape, so that the first and second openings may be disposed at each end of the rounded crescent shape to allow for optimal use of a swirling or cyclone effect for cleaning. The openings are in communication with the housing portion 74 and cleaning liquid contained in the housing portion 74.
The upper portion 72 and housing portion 74 may be comprised of a molded plastic material such as, for example, ABS plastic or high-density polyethylene plastic, but may be also be formed of other suitable materials such as steel, other metals or plastics, and also may be formed integral with each other or as separate removable units of the device.
In a first example of the preferred embodiment, and by way of example only, the height of the assembled upper portion 72 and housing portion 74 may be about 6 to 7 inches, the width about 3 to 4 inches, and the length about 7 to 8 inches, although other dimensions of the device may be suitable. In the preferred embodiment, the device 64 is space conscious and configured to be portable and to take up only a small footprint on a counter top, a salon bench or other work area. In the preferred embodiment, the device 64 comprises round or semi-round openings 56(a), 56(b) sized to permit cleaning of all types of round and square hair brushes and different comb sizes and configurations.
In the preferred embodiment, the hair remover 60 comprises a column 78, a plurality of prongs 82, a bottom end 84 and a top end 80 comprising an edge 86 for grasping with the fingers. The hair remover 60 operates by turning prongs 82 that are preferably specifically spaced and sized, directly into the roller brush 76 while the roller brush 76 is in the “on” position.
The roller brush 76 and hair remover 60 are preferably disposed in approximate parallel relation to one another when the hair remover 60 is disposed in the housing portion 74. In one version, the hair remover 60 makes direct contact with the roller brush 76 at an angle of about 20 to about 30 degrees, which permits optimal hair removal from the roller brush 76 down to the surface of the core 88. In this version, the hair remover 60 makes contact with the core 88 of the roller brush 76 at a set angle to force loose hair onto the hair remover 60, but without causing “skipping” or interruption of the rotating mechanism, which in the preferred embodiment may comprise a motor 70 powered by a 110 AC or 12 V DC power supply, and a gearbox 68.
In the preferred embodiment, the roller brush 76 optimally rotates at about 300 RPM, although other speeds, such as from about 100 RPM to about 400 RPM may be suitable depending upon the items to be cleaned, size and configuration of the device 64.
In another version of the preferred embodiment the roller brush 76 and hair remover 60 are spaced slightly so that they do not touch. In this version, the hair remover may be set at an angle to optimize hair removal from the roller brush 76. For example, the hair remover 60 may be set at an angle of about 20 degrees to about 30 degrees in relation to the roller brush 76. To operate the device 64, the operator inserts a styling comb 62(b) or hairbrush 62(a) to be cleaned into openings 56(a) and/or 56(b). The operator may then press the on/off button 58 to power the motor 70. Motor 70 preferably communicates with a gearbox 68 to impart rotation to roller brush 76, which cleans the hairbrush 62(a) and/or styling comb 62(b).
If operated with the hair remover 60 in opening 56(b), the hair remover 60 may be removed to discard the hair and debris removed from the hairbrush 62(a) or styling comb 62(b). To remove the hair remover 60 from the device, the operator may grasp the edge 86 and rotate and pull the hair remover 60 out of the hairbrush, comb and makeup cleaning device 64 so that accumulated hair from cleaning brushes 62(a) or styling combs 62(b) can be removed. Once the hair remover 60 is out of the device 64, the operator may remove the hair from the hair remover 60 by tapping or shaking over a waste receptacle. The device 64 permits thorough cleaning of hairbrushes and styling combs without the need to manually pull hair from the hairbrush 62(a) or styling comb 62(b) itself and without compromising cleaning performance of the roller brush 76 that might occur from accumulated hair from the hairbrush 62(a) or styling comb 62(b) to be cleaned.
In the preferred embodiment of the invention, the openings 56(a), 56(b) are configured so that the roller brush 76 sits between them and so that they receive respectively a hairbrush or styling comb to be cleaned 62(a), 62(b) and/or the hair remover 60. In a first version of the preferred embodiment, the roller brush 76 sits between openings 56(a) and 56(b), which contain respectively, a hair brush to be cleaned 62(a) and a hair remover 60. In a second version of the preferred embodiment, the device operates with a styling comb 62(b) in one of the openings 56(a), 56(b) and a hair brush 62(a) to be cleaned in the other opening. In a third version of the preferred embodiment, a styling comb 62(b) to be cleaned is placed in one of the openings 56(a), 56(b) and the hair remover 60 is placed in the other opening.
In an alternate roller brush 76 configuration, the device 64 may comprise at least two roller brushes 76 that comprise a spiral brush pattern and which are spaced so that they do not touch. In the alternate version, a first roller brush contacts the styling comb or hairbrush to be cleaned and a second roller brush is configured to catch and remove accumulating hair and debris as it accumulates on the first roller brush.
In the preferred embodiment, the housing portion 74 is filled with cleaning fluid and the device 64 employs agitation of the fluid by the roller brush 76 and bristle-to-bristle contact with the hairbrush 62(a) or styling comb 62(b) to pull, lift and whisk away hair and epidermis debris and oils from the hairbrush 62(a) or styling comb 62(b). Vibration or sonic action and aeration of the cleaning fluid may also be employed in the instant invention to enhance cleaning of the hairbrush 62(b), styling comb 62(b) or other item to be cleaned by creating an active cleaning environment further removing hair, dirt, debris and oils from the items to be cleaned. In one version of the preferred embodiment, the roller brush and roller brush bristles are configured to create optimal aeration of the cleaning fluid. In one version of the preferred embodiment, the opening 56(b), roller brush 76 and hair remover 60 are configured and spaced so that the roller brush 76 and hair remover do not touch and are preferably spaced from one another. By way of example, the end tips of the tufts 34 of the bristle portion of the roller brush 76 may be spaced from about 0.05 cm to about 5.0 cm from the hair remover 60.

The brush frame 8 in Example I preferably has a depth of approximately about 10 cm to about 250 cm, more preferably is between approximately 150 cm to approximately 25 cm in depth, and is most preferably from about 75 cm to about 125 cm in depth, or about 90 cm in depth.
In the preferred embodiment and the alternate embodiment, the support column 40 or core 88 of at least one of the rotating brushes 30 or the roller brush 76 may comprise at least one gear 44, which may be located in a gearbox 68, which directly or indirectly interfaces with a power source. The power source may comprise an electric or battery operated motor 70, a manual hand crank (not shown), or devices comprising a paddlewheel or operating on hydrodynamic principles, such as, for example, those where the kinetic energy of a jet of water is transformed into power at the shaft of the paddle of a paddlewheel. In the alternate embodiment, the rotating brush(es) 30 turn as power is applied to the gear 44 and in the preferred embodiment, applying power to motor 70, preferably causes gears in gearbox 68 to impart rotation to roller brush 76. In the alternate embodiment, it is preferable that the gears and power source are configured so that the rotating brush(es) 30 are each turned inward toward the paintbrush, artist brush arts & crafts or cosmetic brush to be cleaned or sanitized. The brush cleaning device may also be operated without a motor, hand crank, paddlewheel or similar power source, such as by using the operator's up and down and/or sideways motion of the paintbrushes, cosmetic brushes or arts & crafts brushes to be cleaned with a pair of stationary brushes.
In Example I, the drive gear 44 is preferably about 5 cm to about 150 cm in diameter, more preferably is about 10 cm to about 100 cm in diameter, and is most preferably about 20 cm to about 50 cm in diameter, or approximately 35 cm in diameter. In Example I, a suitable motor, if present, may be a 12v electric motor with counter clockwise rotation with a speed of approximately 20600 rpm and a torque of approximately 49.4 mN-m, or other suitable motor known in the art. In one version of an alternate embodiment, the stationary brush 28 and rotating brushes 30 are configured so that the operator's up and down movement of the paintbrush or cosmetic brush in the device replaces the power source, such as the motor or hand crank.
In the alternate embodiment, the tank 10 may be comprised of suitable materials known in the art, such as polyethylene, and preferably comprises non-skid feet 46 arranged in a suitable pattern to stabilize the device, such as at each corner on the outer bottom surface 48 of the tank 10 or at three points on the outer bottom surface 48 of the tank 10, as shown in FIG. 8a. By way of example only, In Example I, the tank 10 may be approximately 10 cm to about 200 cm high, is more preferably about 25 cm to about 150 cm high, and is most preferably between about 50 cm to about 100 cm high, or about 80 cm high. In Example I, the tank 10 is preferably about 10 cm to about 300 cm wide, is more preferably about 50 cm to about 250 cm wide, and is most preferably about 100 cm to about 175 cm, or about 148 cm wide. The tank 10 in Example I is preferably between about 10 cm to about 300 cm deep, is more preferably about 50 cm to about 250 cm deep, and is most preferably about 175 cm to about 200 cm deep, or about 150 cm deep, although other suitable dimensions may be used.
The brush frame 8 in the alternate embodiment is preferably configured so that it sits within the tank 10 above the bottom of the tank 10. This may be accomplished, for example, by way of support elements 50a, 50b disposed at the upper end of the brush frame 8 (see FIG. 5) that interface or rest upon the upper edge 27 of the tank 10, so that the brush frame is immersed in the cleaning fluid in the tank 10, but is supported above the bottom of the tank 10. In the alternate embodiment, the motor housing 6, brush frame 8 and motor, if present, together with the motor cowling 4 are preferably manufactured such that they are secured or can be fitted together. For example, in one version, the motor housing 6, the brush frame 8, and the tank 10 are preferably secured together by way of a latch catch 22, an articulating “Y-arm” 29 and a latch handle 26, although other types of suitable securing means known in the art may be used.
The latch catch 22 may be disposed on the tank 10 and the latch handle 26 may be disposed on the motor housing 6 so that the tank 10, brush frame 8, motor and motor housing 6 will be stable and secured once the latch handle 26 is in a locked position. Once secured, the interface between the motor housing 6 and tank 10 and the interface between the motor housing 6 and top cover 2 will be substantially sealed, which may be accomplished by the action of the latch handle 26, latch catch 22 and Y-arm 29 with a sealing means, such as for example, disposing an O-ring, rubberized gasket or other suitable sealing means, at each interface to be substantially sealed.
The latch handle 26 may be placed in the locked position by engaging the bottom of the latch handle 26 with the latch catch 22 and moving the latch handle in a direction that causes the articulating Y arm 29 to move from a first extended position to a second parallel position to the wall 11 of the tank 10, thereby pulling with it the latch handle 26. To lock the latch handle 26, the operator engages an end of the latch handle 26 with the latch catch 22 and applies slight pressure to the opposite end, or top, of the latch handle 26 so that the latch handle 26 moves to the parallel position, and is thereby in the locked position. To release the latch handle, the operator applies slight pressure to one end, or the top end, of the latch handle 26 to move the latch handle 26 to the extended position, which will release the opposite end, or bottom, of the latch handle 26 from the latch catch 22.
To operate the invention in the alternate embodiment, the user fills the tank 10 with water for cleaning materials such as water-base makeup. Once the tank 10 has been filled, the user then preferably lowers the motor housing 6 onto the tank 10 and locks the latch handle 26.
In a variation of the alternate embodiment, the brush frame 8 is not manufactured integral with the motor housing 6, in which case, it would be lowered onto the tank 10 prior to lowering the motor housing 6 onto the tank 10 and locking the latch handle. Preferably, the top cover 2 has already been secured in place on the motor housing 6 or motor housing unit, but the device may also be configured so that the top cover 2 is a removable component that is fitted in place at the upper surface of the motor housing 6 prior to operation of the device.
In the alternate embodiment, once the tank 10, motor housing 6, brush frame 8 and top cover 2 have been secured in place, the device is plugged into a electrical wall outlet and a power switch 52 on the device is depressed so that power flows to the motor. The user then lowers a cosmetic brush, makeup brush or other item to be cleaned into the throat opening 12 until a light tug is felt on the brush. Preferably the user strokes the brush up and down and from side to side for approximately 15-30 seconds to clean the brush. Excess water may be removed from the brush by pressing on brush groomers 54 disposed on the top cover 2. The brush groomers 54 may be comprised of ridges or protrusions integral with or secured to the top cover 2 to create a squeegee-like action on the paintbrush or cosmetic brush to remove fluid. The cleaned brushes may then be stored in an upright position for drying.
In another version of the alternate embodiment, the makeup brush, cosmetic brush, hairbrush and comb cleaning device may include a distribution manifold and jet nozzles as disclosed in U.S. Pat. No. 6,666,925, with the jet nozzles and distribution manifold being sized for the particular application and brush cleaning device dimensions. The cosmetic, makeup, hairbrush or other item to be cleaned may be positioned between the bristle portions 21 of the rotating brushes by impaling the heel brush on the jet nozzles, as described in U.S. Pat. No. 6,666,925.
In Example I, the distance between the end tips of tufts 34 of the rotating brushes 30a, 30b may be approximately 0.5 cm to about 25 cm, is more preferably 0.75 cm to about 10 cm, and is most preferably between approximately 1.0 and about 5.0 cm, or about 1.6 cm (about 5⁄8 inch). In Example I, the bristle portion 21 of the rotating brushes 30 is preferably configured in a spiral pattern and the distance between the spirals of bristle portion 21 is preferably between approximately 0.25 cm to about 25 cm, is more preferably 10.0 cm to about 5.0 cm and is most preferably between about 1.0 cm and about 5 cm, or about 1.3 cm to about 1.9 cm (about 1⁄2 inch to 3⁄4 inch).
The rotating brush 30 and/or stationary brush 28 or the roller brush 76 may also comprise a spiral pattern of alternating areas of long and/or short single tufts 34, or clumps of long and/or short tufts 34. The tufts 34 of the rotating brush 30 and stationary brush 28, if present, or of the roller brush 76 may be comprised of suitable materials known in the art, such as for example, solid nylon #12 or polypropylene.
Another Embodiment of the Brush Cleaning Device (FIG. 19-25)
FIGS. 19-25 show another embodiment of an apparatus 200 for removing embedded and tangled hair from brushes; these embodiments use a power driven motor. Removing hair from brushes by hand is normally a time consuming and difficult process. This invention removes hair grooming product from the base of the hairbrush and from the teeth of the comb. There is a motor driven rotating brush (250, 255) mounted vertically in a tank or housing 205, which can contain or hold a cleaning/disinfecting solution 280; this apparatus 200 removes hair and grooming product from hair brushes and combs. The rotating brush (250, 255) can be a removable cartridge (255) that can be replaced with a clean cartridge or the used cartridge can be cleaned of hair and reinserted and recycled.
Viewing FIG. 19, there is an apparatus 200 for cleaning brushes with a housing or body with an upper and a lower end; the housing has a tank 205 for holding a cleaning solution 280 and a space for the roller brush assembly; the housing also has an area 230 for the motor 240. There is a cover 210 with a throat or throat opening 215 for the upper end of the housing. The cover also allows for access to the roller brush assembly (a brush cartridge 255 and a core 250); there is a brush cartridge access cap 260 and seal 265. The housing has a vertical axis 295; in FIG. 19, this embodiment shows the brush cartridge and core relatively central to the housing and aligned with the housing axis 295. There is a motor housing 230, a motor 240, a gear train structure 245, which connects and communicates the motor to the core and brush cartridge, an on/off activation switch 270 and a power cord 275. Note that another embodiment may employ other power sources such as batteries or a self-contained power source such as a hand crank dynamo. The tank 205 has an interior 220, and the cover can have a seal 225.
Operation: holding a hair brush in one hand, the user will insert the hair brush into the top opening of the machine (See FIG. 20). The spiral tuft pattern of the rotating brush pulls the brush in until it stops on the bottom of the tank. Using a loose grip on the brush handle, the hairbrush is allowed to spin against the machine's rotating brush. Combs or flat shaped combs can be inserted into a separate opening and pressed against one side of the rotating bristle brush (See FIG. 20, Ref. Part 290).
Brush Design: one preferred brush design uses a spiral pattern (FIG. 22-24); the tuft pattern on the rotating bristle brush can also use a spiral design. Similar to the Archimedes Screw principle, the spiral placed tufts pull and strip hair from the bristles of a hairbrush. The downward motion of the pattern pulls hair, cleaning solution and dirt down and away from the hairbrush.
Viewing FIG. 22-24, this embodiment employs two different types of bristles in the tuft 310 and on a rotating brush 305: a first bristle type 315 (32 PP bristles (from 16 strands folded into the tuft hole); 0.08 diameter) and a second type of bristle 320 (2 PP bristles (from 1 strand folded into the tuft hole); 0.028 to 0.032 diameter). Note that the second type of bristle 320 has a ball shaped head 325 at one terminal end; the specification of the ball shaped head can be approximately 0.035.
There is at least one or multiple tuft holes or openings 330 on the rotating brush 305 or brush cartridge; there is a first type 335 of tuft hole opening (0.08) and a second type 340 of tuft hole opening (0.16). Viewing FIG. 23, the first type 335 of tuft hole opening is at a different and lower elevation in relation to the second type 340 of tuft hole opening. FIG. 24 shows one preferred way of orienting or weaving the two types of bristles in a tuft hole or opening.
Tank Configuration: the shape and volume of the tank or housing can be varied, but shape and volume can have an effect on the efficacy and efficiency of the cleaning process (to a certain extent). For example, there should be an adequate amount of space left around the rotating bristle brush to enhance the flow of cleaning solution and to carry hair and hair products away from the hair brush.
Some Other Brush Design Factors (these are Intended to be Preferred Examples and not Limiting):
1. Spiral Pattern for the brushes and tufts of brushes;
2. Rotation: rotates so the spiral pattern is driving downward;
3. Bristle types: using a combination or mix of soft (weave shape is desirable) and rigid bristles; a first type of bristle and a second type of bristle can be used; bristle dimensions: in one preferred embodiment, the soft and stiff bristles are of equal length. However, other bristle lengths are possible. See FIG. 22 and 24 for the first type of bristle 315 and the second type of bristle 320; note that bristle 320 has a ball shaped head 325 at one end of this second type of bristle.

4. Housing Design:

a. Material: readily available thermoplastics such ABS with UV stabilizer is recommended, but other materials, including without limit PE (polyethylene) or PP (polypropylene), can be used.

b. Seals: rubber or synthetic rubber seals should be placed at all joining of parts. Also, special attention needs to be given to the motor seal to separate the “wet” side from the “dry” side.

c. Component Layout: consideration needs to be given to component layouts that minimize openings between the “wet” side and the “dry” side. Alternative component layouts may move the motor up and above the water line plane so that the motor seal is not constantly immersed.

d. Alternative Features: a separate brush cleaning apparatus being driven off the gear train may be employed for cleaning combs.

5. Rotation Speed: the rotation speed of the rotating brush can be varied; one of the inventors' prototypes operates at about 500 rpm; however, this rotation can be slowed down for optimizing the extraction of hair from the bristles of the hairbrush.

6. Sizes of hair brushes: an important design consideration is how the brush cleaning machine cleans hair brushes of varying diameter. Early prototypes used a “fence” structure that the brush butted up and against when pressed against the rotating cartridge. The distance of the fence from the cartridge should be optimized so that the fence prevents the smaller diameter brushes from jamming between the fence and cartridge. Consideration can also be given to a moving or adjustable fence that closes the gap for cleaning smaller diameter hairbrushes. Alternatively, a fixed position fence could be designed so that it has teeth extending into the cartridge which in effect would also close the gap.

7. Cleaning Solution Specifications: this cleaning solution can include herbicide, disinfectant, and a mild but effective cleaner; the cleaning solution should not be harmful to the tank, housing or seal materials.

8. Motor: in one preferred embodiment, there was a 12v DC motor and 2500 mA transformer; the advantage to a DC motor is safety (low voltage and water); as an alternative, an AC motor and GFI (ground fault interrupter) can also be used. A high torque rating, speed (gear train) and operating motor noise are other important considerations when choosing the motor.
