Description

A cat hair collection device Technical Field

[0001] This invention belongs to the field of pet breeding technology, specifically relating to a cat hair collection device. Background Technology

[0002] Cats are among the most common household pets, bringing joy to people's lives but also causing problems such as excessive shedding and the need to clean up after them. These issues can negatively impact the home environment, deterring some people from owning a cat. Currently, there are few devices on the market that can effectively manage cat hair in the home. A few devices collect loose hair by circulating and filtering the ambient air, but this has a limited coverage area, is not very effective, and has low collection efficiency. Furthermore, the loose hair falling into the environment represents only a portion of the cat's shed fur; a large amount of shed hair remains attached to the cat's body. Circulating and filtering these hairs is largely ineffective against the loose hair on the cat's body, failing to address the root cause of the loose hair in the environment.

[0003] Based on this, the present invention provides a cat hair collection device that actively guides cats and uses a brushing mechanism to process and collect loose hair from the cat's body, reducing the amount of loose hair entering the environment and minimizing the impact on the living environment from the source. At the same time, the treatment effect is better and the efficiency is higher. Summary of the Invention

[0004] The purpose of this invention is to provide a cat hair collection device that solves the shortcomings of existing cat hair collection and processing devices, such as poor collection effect and low efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A cat hair collection device includes a housing with a channel for a cat to pass through. One end of the channel is provided with a guiding mechanism to guide the cat to the channel, and the other end of the channel is fixed with a retractable brushing mechanism. The brushing mechanism includes a brushing unit, which includes a first fixing member and a brushing component. The brushing component is fixed to the first fixing member, so that the brushing unit can adaptively extend and retract to fit the cat's body as cats of different sizes enter.

[0007] In some embodiments of the present invention, the first fixing member in the brushing unit is an arc-shaped plate, and the brushing member is an elastic comb. The first fixing member is biomimetically designed in an arc shape, which, combined with the elastic comb, conforms to the cat's body shape, improving the effect of the elastic comb in scraping loose fur from the cat's body when it passes through the passage.

[0008] In some embodiments of the present invention, the brush bristles are arc-shaped and have elastic comb teeth. The brush bristles are biomimetically designed in an arc shape, and combined with the elastic comb teeth to conform to the cat's body shape, this improves the effect of the elastic comb teeth in scraping loose fur off the cat's body when the cat passes through a passageway.

[0009] Furthermore, the brush component includes an arc-shaped silicone needle plate, a first fixing plate, and a second fixing plate; the arc-shaped silicone needle plate is disposed between the first fixing plate and the second fixing plate. This arrangement of the brush component provides better stability and a better effect of scraping away loose fur when in contact with the cat's body.

[0010] In this invention, a first spring is provided between the bristle component and the first fixing component, and the bristle component and the first fixing component are elastically connected by the first spring. With this arrangement, the entire bristle unit structure is flexibly connected, the bristle component moves smoothly, has a certain range of elastic movement during brushing, conforms more closely to the cat's body, and is less likely to cause harm to the cat.

[0011] The invention can be further improved by including a hair-removing component in the bristle unit. This hair-removing component has through holes adapted to the elastic comb teeth of the bristle unit, and is fitted onto the elastic comb teeth through these holes. This arrangement allows the hair-removing component to limit the movement of the elastic comb teeth, maintaining the strength of the bristle unit and improving the brushing effect. Furthermore, after the cat passes through the channel and completes the brushing process, loose hair adheres to the bristle unit. By extending and retracting the bristle unit, the hair-removing component obstructs and scrapes the bristle unit, thus removing the loose hair for easy collection.

[0012] Furthermore, it also includes a second fixing member, to which the hair-removing component is slidably connected, and the hair-removing component is also connected to the second fixing member via a second spring. With this configuration, the hair-removing component can be adjusted according to different cats passing through the passageway, better conforming to the cat's body shape, and will not cause stress or harm to the cat.

[0013] Furthermore, the brush bristle component is provided with a fixed shaft, and the first fixing component is sleeved on the fixed shaft.

[0014] In some embodiments of the present invention, the brush unit comprises three units: a first brush unit, a second brush unit, and a third brush unit. The first brush unit is located at the top of the channel, while the second and third brush units are located on either side of the channel, arranged symmetrically. This separate arrangement of the brush units improves their flexibility, better accommodating cats of different sizes passing through the channel. Having three brush units allows for coverage of the top and sides of the cat's body, providing a larger area of ​​coverage and achieving better removal of loose fur.

[0015] In this invention, the brushing mechanism further includes a drive unit, which is fixedly connected to a first fixing member of the brushing unit. The drive unit drives the first fixing member to move back and forth within the channel. The drive unit enables the extension and retraction of the brushing mechanism, thus scraping away loose fur from the cat's body.

[0016] Furthermore, the drive unit includes a first motor, a synchronous belt, and a fixing block; the synchronous belt is wound around several guide wheels, and the output shaft of the first motor is connected to the synchronous belt for transmission; the fixing block is fixedly connected to the synchronous belt and to the first fixing member of the brushing unit. The first motor drives the synchronous belt to reciprocate, and then the fixing block drives the brushing unit to move, thereby enabling the brush to scrape away loose fur on the cat's body.

[0017] Furthermore, the drive unit also includes an adjusting block, which is fixedly connected to the first fixing member of the bristle unit. The adjusting block is sleeved on the slide rod via a first bearing, allowing the adjusting block to move back and forth along the slide rod. This arrangement makes the movement of the bristle unit more stable during the scraping of loose hair.

[0018] Furthermore, the channel has a fixing plate, and the first motor, fixing block and guide wheel in the drive unit are all fixed on the fixing plate; the slide rod is fixed on the fixing plate; the second fixing member in the brush unit is also fixed on the fixing plate.

[0019] In some embodiments of the present invention, there is one first motor, one synchronous belt, three fixed blocks, and six adjusting blocks; each fixed block corresponds to one brush unit, and every two adjusting blocks correspond to one brush unit.

[0020] In this invention, the brushing mechanism further includes a pressure adjustment unit, which includes a sensor and is electrically connected to a drive unit. The pressure adjustment unit detects the pressure when the brush bristles in the brushing unit contact the cat's body, and then the drive unit adjusts the extension and retraction distance of the brush bristles to maintain a better fit with the cat's body at all times. This effectively removes loose fur without causing harm to the cat due to excessive pressure.

[0021] The present invention can be improved as follows: the brushing mechanism further includes a video recognition unit, which is disposed at the channel entrance and electrically connected to the drive unit. The video recognition unit identifies the cat before it enters the channel, determining its species and size. Combined with an algorithm, the drive unit is controlled to adjust the position of the brushing unit and the size of the channel through which the cat passes, thereby achieving the optimal fit between the brushing unit and the cat's body, and better removing loose fur from the cat's body.

[0022] Furthermore, the video recognition unit includes a camera, which is fixed outside the housing and located outside the brush mechanism.

[0023] The present invention can also be improved in the following way: the induction mechanism is a feeding mechanism, which is fixed on the top of the housing and is used to put cat food into the channel to induce the cat to pass through the brushing mechanism and enter the channel.

[0024] The invention can be further improved by including a collection mechanism located at one end of the channel; the guiding mechanism is located between the collection mechanism and the brushing mechanism, and is close to the collection mechanism.

[0025] In some embodiments of the present invention, the collection mechanism includes a filter screen, a scraping assembly, a collection box, and a fixing frame; the filter screen is fixed on the fixing frame, and the collection box is disposed at the bottom of the fixing frame; the scraping assembly is fixed on the fixing frame, such that the scraping assembly moves up and down along the fixing frame to scrape the floating hair on the filter screen into the collection box.

[0026] Furthermore, the scraping assembly includes a third motor, a coupling, a lead screw, and a scraper; the output shaft of the third motor is connected to the lead screw via the coupling, and the bottom of the lead screw is fixed to a fixed frame via a second bearing; a brush is fixed on the scraper, and the scraper is movably connected to the lead screw via a fixed sleeve.

[0027] Furthermore, the scraper is also provided with a second compression spring, one end of which is fixed to the scraper and the other end of which abuts against the brush, so that the brush fits tightly against the filter screen.

[0028] Furthermore, the collection mechanism also includes a lint removal assembly, which is fixed on a mounting frame and located above the collection box. The lint removal assembly includes a fourth motor, a rotary guide, and a lint-spinning plate. The fourth motor is connected to the rotary guide, and the lint-spinning plate is fixed to the rotary guide. The rotary guide guides the loose lint scraped from the filter screen by the scraper into the collection box.

[0029] Furthermore, the rotating guide is V-shaped, with a guide plate on one side and a hollow opening on the other side.

[0030] Furthermore, it also includes a sealing cover plate, which is fixed to the mounting frame and forms a sealed cavity with the mounting frame. The third motor, coupling, and lead screw are all located within the sealed cavity. A sealing strip is provided between the sealing cover plate and the filter screen. This arrangement provides sealing protection for the third motor, coupling, and lead screw, preventing the cat hair collected by the filter screen from affecting the movement of the lead screw.

[0031] In some embodiments of the present invention, a collection mechanism is further included, the collection mechanism comprising a collection box; the collection box is disposed at the bottom of the housing.

[0032] The present invention can also be improved in the following way: the cat hair collection device further includes a blower mechanism, which includes a first blower, an air duct frame, and an air duct switching component; the air duct frame is provided with a first air duct and a second air duct; the air outlet of the first blower is connected to the first air duct, and the air outlet of the first blower is also connected to the second air duct; the air duct switching component is disposed at the air outlet of the first blower, so that the airflow blown by the first blower enters the first air duct and blows towards the brushing mechanism, or the airflow is blown towards the collection mechanism through the second air duct. The present invention blows airflow towards the brushing mechanism through the first air duct and towards the collection mechanism through the second air duct.

[0033] In some embodiments of the present invention, the air duct switching component includes a first baffle plate and a fifth motor; the first baffle plate is hinged to the air duct frame, and the first baffle plate and the fifth motor are connected by transmission, so that the fifth motor drives the first baffle plate to rotate and switch the airflow direction of the air blown out by the first blower.

[0034] The present invention can be improved in the following way: the cat hair collection device further includes an airflow generating channel, which is connected to the channel through which the cat passes to form a circulating airflow channel, so that the circulating airflow generated by the circulating airflow channel carries the hair brushed off by the brushing mechanism to the collection mechanism to complete the collection of loose hair on the cat.

[0035] Furthermore, the airflow generating channel includes a second blower, an air inlet, and an air outlet; the air inlet is connected to the air inlet of the second blower through an airflow channel, and the air outlet is connected to the air outlet of the second blower through an airflow channel; the air inlet is located at one end of the collecting mechanism, and the air outlet is located at one end of the brushing mechanism.

[0036] Furthermore, a filter screen is provided at the connection between the air inlet and the collection mechanism.

[0037] In some embodiments of this invention, the airflow generating channel further includes an airflow switching component; the air outlet is provided with two outlets, namely a first air outlet and a second air outlet, which are respectively located on both sides of the brushing mechanism, so that the airflow switching component switches the direction of the generated airflow to blow the airflow towards the first air outlet or the second air outlet. With this arrangement, the cat hair on the brushing mechanism is blown towards the collecting mechanism through the first air outlet, preventing the scraped cat hair from adhering to the brushing mechanism and affecting the scraping effect, while the cat hair in the passageway is blown towards the collecting mechanism through the second air outlet.

[0038] Furthermore, the airflow switching component includes a second baffle plate and a sixth motor; the second baffle plate is hinged to the housing, and the second baffle plate and the sixth motor are connected by a drive, so that the sixth motor drives the baffle plate to rotate and switch the direction of the airflow blown out by the second blower.

[0039] Furthermore, it also includes an air guiding assembly, which includes a first air guiding component and a second air guiding component; the first air guiding component is disposed between the housing inlet and the brush mechanism, and the first air guiding component is connected to the first air outlet; the second air guiding component is disposed between the brush mechanism and the collection mechanism, and is close to the brush mechanism, and the second air guiding component is connected to the second air outlet.

[0040] Furthermore, the air outlet of the first air guide is directly opposite the bristle component of the bristle unit of the bristle mechanism and is arranged along the passageway direction; the air outlet of the second air guide is arranged along the passageway direction and faces the collection mechanism direction.

[0041] In this invention, the housing has an entrance for the cat to enter near the brushing mechanism, and a vent hole near the collecting mechanism, with the vent hole directly opposite the entrance. By providing a vent hole at one end of the housing, a portion of the circulating airflow from the circulating airflow channel flows out through the vent hole, which acts as a vent. This prevents the circulating airflow from being blocked at the other end of the housing and flowing back in the opposite direction, creating turbulence and preventing some cat hair in the passageway from being effectively blown towards the collecting mechanism, thus reducing the effectiveness of the circulating airflow in collecting the loose hair. Verification has shown that providing a vent hole, compared to not having one, better directs the loose hair from the brushing mechanism and passageway towards the collecting mechanism, significantly improving the overall efficiency of cat hair collection.

[0042] The present invention has the following beneficial effects:

[0043] (1) The cat hair collection device of the present invention is equipped with an induction mechanism and a brushing mechanism in the channel. Under the action of the induction mechanism, the cat passes through the brushing mechanism to complete the active processing and collection of the loose hair on the cat's body, reducing the hair from entering the living environment, reducing the difficulty of subsequent processing, and at the same time, the collection effect is good and the efficiency is higher.

[0044] (2) The cat hair collection device of the present invention also collects and concentrates the cat hair scraped off by the brushing mechanism through the collection mechanism and the blower mechanism, which improves the collection effect and further improves the processing efficiency, while making it convenient to operate; moreover, the device is equipped with an airflow generation channel, which is connected to the cat passage to form a circulating airflow channel, generating circulating airflow. Compared with unidirectional airflow collection, the airflow can flow continuously and efficiently in the device, quickly collecting the loose hair scraped off the cat, resulting in higher collection efficiency.

[0045] (3) The cat hair collection device of the present invention adopts an elastic connection structure for the brush unit, which can better fit the cat's body, reduce the risk of stress reaction to the cat, reduce harm to the cat, and is more humane. Combined with the video recognition unit and the pressure adjustment unit, the initial optimal contact position between the brush mechanism and the cat is preset before the cat enters the channel. When the cat passes through the brush mechanism, the contact degree between the brush mechanism and the cat is adjusted in real time according to the pressure to obtain a better effect of scraping off loose hair, while avoiding harm to the cat due to being too tight or having too much force.

[0046] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0087] The technical solution of the present invention will be further described below with reference to specific embodiments, so that those skilled in the art can better understand and implement the technical solution of the present invention.

[0088] Example 1

[0089] As shown in Figure 1-24, the cat hair collection device includes a housing 100, a brushing mechanism 200, an induction mechanism 300, a collection mechanism 400, and a blower mechanism 500.

[0090] The housing 100 is elongated cylindrical, with an inlet 101 at one end and a ventilation hole 102 at the other end. A one-way outlet 103 is located on the side wall of the housing 100 near the ventilation hole 102, allowing the cat to enter the housing 100 through the inlet 101 and exit through the one-way outlet 103, thus collecting loose fur from the cat. Inside the housing 100, a passageway is formed from the inlet 101 to the one-way outlet 103 for the cat to pass through.

[0091] A vertically arranged fixing plate 104 is fixed at the bottom of the housing 100 near the inlet 101. The fixing plate 104 has a through hole for the cat to pass through. The brushing mechanism 200 is located inside the housing 100 and is fixed to the fixing plate 104. The brushing mechanism 200 includes a brushing unit and a driving unit. The driving unit is used to provide driving force for the movement of the brushing unit.

[0092] The brushing unit includes a first fixing member 201 and a brush member 202. The brush member 202 is fixed to the first fixing member 201, allowing the brushing unit to adaptively extend and adjust to fit the cat's body according to different cat sizes. In this embodiment, the first fixing member 201 in the brushing unit is an arc-shaped plate, and the brush member 202 is an elastic comb.

[0093] To facilitate the removal of loose hairs adhering to the brush bristles 202, the brush unit also includes a hair removal component 203. The hair removal component 203 has through holes adapted to the elastic comb teeth of the brush bristles 202, and is fitted onto the elastic comb teeth through these holes. With this arrangement, after the cat passes through the channel and completes brushing, loose hairs adhere to the brush bristles 202. By extending and retracting the brush bristles 202, the hair removal component 203 blocks and scrapes against the brush bristles 202, thereby removing the loose hairs from the brush unit for easy collection.

[0094] In this embodiment, the drive unit is fixedly connected to the first fixing member 201 of the brushing unit, and the drive unit drives the first fixing member 201 to move back and forth within the channel. The drive unit realizes the telescopic movement of the brushing mechanism 200 to complete the scraping of loose hair on the cat. Specifically, the drive unit includes a first motor 204, a synchronous belt 205, a fixing block 206, an adjusting block 207, and a tensioning member 208. The synchronous belt 205 is wound around several guide wheels 209; the output shaft of the first motor 204 is connected to the synchronous belt 205; the fixing block 206 is fixedly connected to the synchronous belt 205 and to the first fixing member 201 of the brushing unit. The adjusting block 207 is fixedly connected to the first fixing member 201 of the brushing unit. The adjusting block 207 is sleeved on the slide rod 210 through the first bearing 211, so that the adjusting block 207 moves back and forth along the slide rod 210, making the movement of the brushing unit more stable during the scraping of loose hair. Tensioner 208 is used to adjust the tension of timing belt 205.

[0095] In this embodiment, the first motor 204, fixing block 206, tensioning member 208, and guide wheel 209 are all fixed on the fixing plate 104; the slide rod 210 is fixed on the fixing plate 104; and the hair removal member 203 in the brushing unit is also fixed on the fixing plate 104. There are three brushing units: a first brushing unit, a second brushing unit, and a third brushing unit. The first brushing unit is located on the top of the fixing plate 104, while the second and third brushing units are located on both sides of the fixing plate 104, arranged symmetrically. The separate arrangement of the brushing units improves their flexibility, better accommodating cats of different sizes passing through the passage. Correspondingly, there are three fixing blocks 206 and six adjusting blocks 207; each fixing block 206 corresponds to one brushing unit, and every two adjusting blocks 207 correspond to one brushing unit. There is one first motor 204 and one synchronous belt 205; the three brushing units can be controlled to move simultaneously using one first motor 204 and one synchronous belt 205.

[0096] The brushing mechanism 200 also includes a pressure adjustment unit, which includes a sensor 212 and is electrically connected to the drive unit. The pressure adjustment unit detects the pressure when the brush element 202 in the brushing unit contacts the cat's body. Then, the drive unit adjusts the extension and retraction distance of the brush element 202 to maintain a better fit with the cat's body at all times, effectively scraping away loose fur without causing harm to the cat due to excessive pressure. In this embodiment, the sensor 212 can be a photoelectric sensor or a pressure sensor.

[0097] The brushing mechanism 200 also includes a video recognition unit, which is located at the top of the inlet 101 end of the housing 100 and is electrically connected to the drive unit. The video recognition unit identifies the cat before it enters the channel, determining its species and size. Combined with an algorithm, the drive unit is controlled to adjust the position of the brushing unit and the size of the channel through which the cat passes, thereby achieving the optimal fit between the brushing unit and the cat's body for better removal of loose fur. Specifically, the video recognition unit includes a camera 213, which is fixed to the top of the inlet 101 end of the housing 100.

[0098] To lure the cat into the housing 100 and through the channel, this embodiment of the cat hair collection device also includes an induction mechanism 300. The induction mechanism 300 can be any substance, scent, or toy that can attract the cat, and there are no restrictions. However, food is the most commonly chosen and preferred way to attract the cat through the brushing mechanism 200 and into the channel. Therefore, in this embodiment, the induction mechanism 300 is a feeding mechanism.

[0099] The feeding mechanism is fixed to the top of the housing 100 and is used to dispense cat food into the channel to guide the cat through the brushing mechanism 200 into the channel. A ventilation hole 102 is provided at one end of the feeding mechanism near the housing 100, and a cat food container 313 is placed directly below the feeding mechanism. The feeding mechanism includes a cylinder 301, a food dispensing box 302, an extrusion assembly, and a motor assembly. The cylinder 301 is connected to the food dispensing box 302, with a food inlet 303 at the bottom of the cylinder 301 and a food outlet 304 at the bottom of the food dispensing box 302. The extrusion assembly is located inside the food dispensing box 302, and the motor assembly is fixed to the bottom of the food dispensing box 302. The motor assembly is connected to the extrusion assembly, causing the motor assembly to drive the extrusion assembly to move and bring the cat food from the cylinder 301 into the food dispensing box 302, and then extrude it from the food dispensing box 302.

[0100] Specifically, in this embodiment, the extrusion assembly includes a feed-discharging rotary blade 305, a first compression spring 306, an elastic connecting block 307, and an extrusion rotary wheel 308. The feed-discharging rotary blade 305 is disposed at the bottom of the cylinder 301 and fixed to the top of the extrusion rotary wheel 308, and is located inside the cylinder 301. An extrusion rotary blade 309 is sleeved on the extrusion rotary wheel 308 and is located below the feed-discharging rotary blade 305. An elastic connecting block 307 is disposed inside the extrusion rotary wheel 308, and the extrusion rotary wheel 308 is connected to the motor assembly for transmission through the elastic connecting block 307. The first compression spring 306 is placed inside the extrusion rotary wheel 308, one end of the first compression spring 306 is fixedly connected to the top of the elastic connecting block 307, and the other end is fixedly connected to the top of the extrusion rotary wheel 308.

[0101] The motor assembly includes a second motor 310, a sensor plate 311, and a Hall switch 312. The sensor plate 311 is sleeved on the output shaft of the motor and is connected to an elastic connecting block 307. The elastic connecting block 307 is sleeved outside the sensor plate 311, so that the elastic connecting block 307 is movable relative to the sensor plate 311 along the direction of the motor output shaft. The Hall switch 312 is fixed on the sensor plate 311.

[0102] The cat enters the housing 100 due to the induction mechanism 300, passes through the channel and is brushed by the brushing mechanism 200. Loose hair will accumulate inside the housing 100. In order to better collect the loose hair scraped from the cat's body, the cat hair collection device of the present invention also includes a collection mechanism 400. The collection mechanism 400 is located at the other end of the housing 100 near the ventilation hole 102, and is directly opposite the brushing mechanism 200. The induction mechanism 300 is located between the collection mechanism 400 and the brushing mechanism 200.

[0103] As shown in the figure, the collection mechanism 400 includes a filter screen 401, a fixing frame 402, a collection box 403, a scraping component, and a hair removal component. The filter screen 401 is fixed on the fixing frame 402, and the collection box 403 is located at the bottom of the fixing frame 402; the scraping component is fixed on the fixing frame 402, so that the scraping component moves up and down along the fixing frame 402 to scrape the loose hair on the filter screen 401 into the collection box 403.

[0104] The scraping assembly includes a third motor 405, a coupling 406, a lead screw 407, and a scraper 408. The third motor 405 is fixed on a mounting frame 402, and the output shaft of the third motor 405 is connected to the lead screw 407 via the coupling 406. The bottom of the lead screw 407 is fixed to the mounting frame 402 via a second bearing 412. A brush 409 is fixed on the scraper 408, and the scraper 408 is movably connected to the lead screw 407 via a fixing sleeve 411. In this embodiment, a second compression spring 410 is also provided on the scraper 408. The second compression spring 410 is located between the brush 409 and the scraper 408, with one end fixed to the scraper 408 and the other end abutting against the brush 409, so that the brush 409 fits tightly against the filter screen 401.

[0105] The down-feather assembly is fixed to the mounting frame 402 and located above the collection box 403. The down-feather assembly includes a fourth motor 413, a rotating guide 414, a down-spinning plate 415, and a door panel 416. The rotating guide 414 is V-shaped, with a guide plate 417 on one side and a hollow opening 418 on the other. The fourth motor 413 is fixed to the mounting frame 402, and the rotating guide 414 is hinged to the mounting frame 402, with the fourth motor 413 and the rotating guide 414 being connected in a transmission manner. The down-spinning plate 415 is fixed to the rotating guide 414 and is positioned opposite to the guide plate 417. As the rotating guide 414 rotates forward, the lint-scraping plate 415 scrapes the loose cat hair from the bottom of the filter screen 401, causing it to fall to the side of the guide plate 417. Then, the rotating guide 414 rotates in the opposite direction, causing the loose cat hair to fall from the guide plate 417 side towards the perforated opening 418 side, thus passing through the perforated opening 418 and falling into the collection box 403. This completes the collection of loose cat hair scraped from the filter screen 401 into the collection box 403 for easy processing. The door panel 416 is hinged to the rotating guide 414, providing shielding and protection for the rotating guide 414 while preventing cat hair from overflowing and affecting the environment.

[0106] The collection mechanism 400 also includes a sealing cover plate 404, which is fixed to the fixing frame 402 and forms a sealed cavity with the fixing frame 402. The third motor 405, coupling 406, and lead screw 407 are all located within the sealed cavity. A sealing strip is provided between the sealing cover plate 404 and the filter screen 401. The sealing cover plate 404 and the sealing strip provide sealing protection for the third motor 405, coupling 406, and lead screw 407, preventing the cat hair collected by the filter screen 401 from affecting the movement of the lead screw 407.

[0107] In order to better collect the cat hair scraped by the brushing mechanism 200 inside the housing 100 into the collection mechanism 400, the cat hair collection device of the present invention further includes a blower mechanism 500, which is disposed between the brushing mechanism 200 and the collection mechanism 400 and is close to the brushing mechanism 200.

[0108] The blower mechanism 500 includes a first blower 501, an air duct frame 502, and an air duct switching component. The air duct frame 502 is fixed to the bottom of the housing 100, and the first blower 501 is fixedly connected to the air duct frame 502. The air duct frame 502 is provided with a first air duct 503 and a second air duct 504. The air outlet of the first blower 501 is connected to the first air duct 503, and the air outlet of the blower 501 is connected to the second air duct 504. The air duct switching component is located at the air outlet of the first blower 501, allowing the airflow blown by the first blower 501 to enter either the first air duct 503 or the second air duct 504. The airflow is blown towards the bristle mechanism 200 through the first air duct 503, which helps to remove loose hairs from the bristle mechanism 200. Combined with the airflow being blown towards the collection mechanism 400 through the second air duct 504, the loose hairs in the channel are ultimately blown towards the collection mechanism 400.

[0109] In this embodiment, the air duct switching component includes a first baffle plate 505 and a fifth motor 506; the first baffle plate 505 is hinged to the air duct frame 502, and the first baffle plate 505 and the fifth motor 506 are connected by transmission, so that the fifth motor 506 drives the first baffle plate 505 to rotate and switch the airflow direction of the first blower 501.

[0110] In this embodiment, the cat hair collection device also includes a control system, which includes a processor unit electrically connected to a drive unit, a pressure regulating unit, and a video recognition unit; the processor unit is also electrically connected to each motor in the motor assembly, the hair scraping assembly, and the air duct switching assembly.

[0111] Implementation 2

[0112] As shown in Figures 25-39, the cat hair collection device includes a housing 100, a brushing mechanism 200, an induction mechanism 300, a collection mechanism 400, and an airflow generation channel 600. Unlike Embodiment 1, the collection mechanism 400 has a different structure, and the airflow generation channel 600 and the blower mechanism 500 have different structures and arrangements. The airflow generation channel 600 and the channel through which the cat passes are connected at both ends within the housing 100 to form a circulating airflow channel, generating circulating airflow to collect cat hair. Furthermore, the brushing mechanism 200 employs an elastic connection structure, reducing the risk of stress and minimizing harm to the cat when it comes into contact with its body.

[0113] The housing 100 is elongated cylindrical. One end of the housing 100 has an entrance 101 for cats to enter, and a brushing mechanism 200 is located near the entrance 101. The other end of the housing 100 has a cat hair collection mechanism 400. A vent 105 is located near the collection mechanism 400, directly opposite the entrance 101. A transparent window 106 and a one-way exit 103 are located on the side wall of the housing 100 near the cat hair collection mechanism 400, allowing the cat to enter the housing 100 through the entrance 101 and exit through the one-way exit 103, thus collecting loose cat hair. Inside the housing 100, a passageway from the entrance 101 to the one-way exit 103 is formed for the cat to pass through. The transparent window 106 expands the cat's field of vision within the passageway, reducing its fear of entering the device and making it more cat-friendly. In this embodiment, the collection mechanism 400 includes a collection box 403; the collection box 403 is located at the bottom of the housing 100, below the vent 105, and is designed to be removable by a pull-out method, so as to facilitate the cleaning of the hair collected in the collection box 403.

[0114] An airflow generating channel 600 is located at the bottom of the housing 100. The airflow generating channel 600 includes a second blower 601, an air inlet, and an air outlet. The air inlet is connected to the air inlet of the second blower 601 via the airflow channel, and the air outlet is connected to the air outlet of the second blower 601 via the airflow channel. The air inlet is located within the collection box 403 of the collection mechanism 400 in the housing 100, and a filter screen 401 is provided at the connection between the air inlet and the collection box 403. The air outlet is located at one end of the brushing mechanism 200 inside the housing 100. The airflow generating channel 600's location at the bottom of the housing 100, with a lower center of gravity, improves the stability of the entire cat hair collection device. In this invention, the cat passage channel and the airflow generation channel 600 are arranged side by side. The two ends of the airflow generation channel 600 are connected to the two ends of the passage channel, forming a large airflow circulation path inside the entire cat hair collection device. Compared with the unidirectional airflow channel in Embodiment 1, the airflow is fully utilized, saving energy and increasing the collection efficiency. It can effectively collect the hair collected by the shaving mechanism, and the overall structure of the device is more reasonable.

[0115] To achieve better airflow circulation, the airflow generation channel 600 also includes an airflow switching component. This component includes a second baffle plate 602 and a sixth motor 603. The second baffle plate 602 is hinged to the airflow channel, and the second baffle plate 602 and the sixth motor 603 are connected by a drive mechanism, allowing the sixth motor 603 to rotate the second baffle plate 602 and switch the direction of the airflow from the second blower 601. Two air outlets are provided: a first air outlet and a second air outlet. The first air outlet is located on the side of the brushing mechanism 200 near the inlet 101 of the housing 100, and the second air outlet is located on the side of the brushing mechanism 200 away from the inlet 101 of the housing 100. This allows the airflow switching component to switch the airflow direction, directing the airflow towards either the first or second air outlet. This design allows for the opening of different air vents depending on the cat's position within the housing 100, achieving better airflow and cat hair collection. The first air vent primarily blows down loose hair adhering to the brushing mechanism 200, while the second air vent mainly blows loose hair from the channel towards the collection mechanism 400. To better collect the loose cat hair scraped by the brushing mechanism 200 and the loose hair in the channel within the housing 100 into the collection mechanism 400, the cat hair collection device of this invention also includes an air guide assembly, comprising a first air guide 604 and a second air guide 605. The first air guide 604 is positioned between the inlet 101 of the housing 100 and the brushing mechanism 200, and is connected to the first air vent. The second air guide 605 is positioned between the brushing mechanism 200 and the collection mechanism 400, and is close to the brushing mechanism 200, and is connected to the second air vent. In this invention, the air outlet of the first air guide 604 is directly opposite the bristle member 202 of the bristle unit of the bristle mechanism 200 and is arranged along the passageway direction; the air outlet of the second air guide 605 is arranged along the passageway direction and faces the collection mechanism 400.

[0116] A vertically arranged fixing plate 104 is fixed at the bottom of the housing 100 near the inlet 101. The fixing plate 104 has a through hole for the cat to pass through. The brushing mechanism 200 is fixed on the fixing plate 104. The brushing mechanism 200 includes a brushing unit and a drive unit. The drive unit is used to provide driving force for the movement of the brushing unit.

[0117] The brushing unit includes a first fixing member 201 and a brush member 202. The brush member 202 is fixed to the first fixing member 201, and a first spring 215 is provided between the brush member 202 and the first fixing member 201. The brush member 202 and the first fixing member 201 are elastically connected by the first spring 215, allowing the brushing unit to adaptively extend and adjust to fit the body of cats of different sizes. The brush member 202 is arc-shaped and has elastic comb teeth. The brush member 202 is biomimetically designed to be arc-shaped, and combined with the elastic comb teeth to fit the cat's body shape, it can improve the effect of the elastic comb teeth scraping off loose fur on the cat's body when the cat passes through the passage. Specifically, the brush member 202 includes an arc-shaped silicone needle plate 2021, a first fixing plate 104, and a second fixing plate 104; the arc-shaped silicone needle plate 2021 is located between the first fixing plate 104 and the second fixing plate 104.

[0118] To facilitate the removal of loose hairs adhering to the bristle component 202, the bristle unit also includes a hair removal component 203. The hair removal component 203 has through holes adapted to the elastic comb teeth of the bristle component 202, and is fitted onto the elastic comb teeth through these holes. This design allows the hair removal component 203 to provide a certain degree of restraint on the bristle component 202, maintaining its strength and improving the brushing effect. Furthermore, after the cat passes through the channel and completes brushing, loose hairs adhere to the bristle component 202. By extending and retracting the bristle component 202, the hair removal component 203 blocks and scrapes the bristle component 202, thereby removing the loose hairs from the bristle unit for easy collection.

[0119] The brushing unit also includes a second fixing member 214. The hair removal component 203 is slidably connected to the second fixing member 214. The hair removal component 203 is also connected to the second fixing member 214 via a second spring 216, allowing the hair removal component 203 to slide back and forth under the action of the second spring 216. With this design, the hair removal component 203 can be adjusted according to different cats passing through the passageway, better conforming to the cat's body shape and preventing stress or injury. The brushing component 202 is equipped with a fixing shaft 217, and the first fixing member 201 is sleeved on the fixing shaft 217. This design provides a flexible connection between the entire brushing unit structure, ensuring smooth movement of the brushing component 202. During the brushing process, it has a certain range of elasticity, resulting in a closer fit to the cat's body and minimizing the risk of injury. When the brush 202 needs to move into the passageway to shave, the first fixing member 201 drives the brush 202 to move into the passageway (to the maximum stroke position of the brush 202) through the first spring 215. At the same time, under the action of the brush 202, the hair removal member 203 is moved into the passageway. At this time, the hair removal member 203 is in contact with the brush 202, and the brush 202 is in contact with the cat's body to shave. After shaving is completed, the first fixing member 201 moves outward, and the brush 202 moves outward and resets under the combined action of the hair removal member 203, the second spring 216 and the first spring 215. The first fixing member 201 continues to move outward, and under the blocking action of the hair removal member 203, the cat hair on the elastic comb teeth is scraped off.

[0120] In this embodiment, the drive unit is fixedly connected to the first fixing member 201 of the brushing unit, and the drive unit drives the first fixing member 201 to move back and forth within the channel. The drive unit realizes the telescopic movement of the brushing mechanism 200 to complete the scraping of loose hair on the cat's body.

[0121] The brushing mechanism 200 also includes a pressure adjustment unit, which includes a sensor 212 and is electrically connected to the drive unit. The pressure adjustment unit detects the pressure when the brush element 202 in the brushing unit contacts the cat's body. Then, the drive unit adjusts the extension and retraction distance of the brush element 202 to maintain a better fit with the cat's body at all times. This effectively removes loose fur without causing stress or injury to the cat due to excessive pressure. In this embodiment, the sensor 212 can be either a photoelectric sensor or a pressure sensor.

[0122] The brushing mechanism 200 also includes a video recognition unit, which is located at the top of the entrance 101 end of the housing 100 and is electrically connected to the drive unit. The video recognition unit identifies the cat before it enters the passageway, determining its species and size. Combined with an algorithm, the drive unit is controlled to adjust the position of the brushing unit and the size of the passageway for the cat, thereby achieving the optimal fit between the brushing unit and the cat's body for better removal of loose fur. Specifically, the video recognition unit includes a camera 213, which is fixed to the top of the entrance 101 end of the housing 100.

[0123] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention. The implementation of the present invention is not limited thereto. All other modifications, substitutions or alterations made by those skilled in the art based on the above content of the present invention and in accordance with ordinary technical knowledge and common practices in the art, without departing from the basic technical concept of the present invention, shall fall within the scope of protection of the present invention.
