Description

Technical Field

[0001] This invention relates to a pet carrier, belonging to the field of pet carrier technology. Background Technology

[0002] Conventional pet carriers are mostly used as temporary transport boxes or sleeping places for pets at night. When used as temporary transport boxes, pets are prone to being startled during transport because there are no distractions inside the carrier. For cats, being startled can easily lead to stress reactions, which can even be fatal. Therefore, conventional pet carriers cannot provide the necessary distractions to reduce stress in cats. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a pet carrier that solves the problem that conventional pet carriers in the prior art cannot attract the attention of pet cats and reduce their fright, thus making cats easily stimulated and causing stress reactions.

[0004] The technical problem to be solved by the present invention is achieved by the following technical solution: a pet carrier, comprising a housing, the interior of which is hollow and has a one-way opening.

[0005] The combing barrel is located at the opening inside the box, and a sliding groove is provided on the inner side of the combing barrel.

[0006] The brush structure is set inside the slide groove, and the brush structure rotates along the axis of the combing barrel within the slide groove.

[0007] The drive structure is located inside the housing and is connected to the brush structure. The drive structure drives the brush structure to rotate.

[0008] The brush structure sweeps radially across the comb barrel as it rotates.

[0009] By adopting the above technical solution, the drive structure drives the brush structure to sweep radially along the combing barrel. When the cat enters the combing barrel through the opening of the box, the cat's fur is combed radially by the brush structure. Since cat fur naturally extends from the head to the tail in a normal state, the cat's fur will become messy after being combed horizontally by the brush structure. Because cats are used to licking and grooming their fur with their tongues after it becomes messy, the cat will curl up and groom itself after entering the box. This helps stabilize the cat's emotions during the process and prevents stress reactions that could lead to sudden death, thus protecting the cat's safety during transport.

[0010] The present invention is further configured such that: the driving structure includes

[0011] The drive housing is fixed to the inner wall of the housing and located on the radial side of the combing barrel. The drive housing is hollow.

[0012] The passageway is located on the side wall of the drive box facing the combing drum.

[0013] The drive motor is fixed to one side wall of the housing with an opening. The drive motor has an output shaft that extends into the drive housing.

[0014] The drive wheel is rotatably mounted inside the drive housing. The drive wheel is coaxially mounted and fixedly connected to the output shaft of the drive motor. Part of the drive wheel extends from the opening of the through channel to the outside of the drive housing and is connected to the brush structure.

[0015] The invention is further configured such that: the brush structure includes a sliding ring fitted to the bottom wall of the chute, the sliding ring is annular, a filter layer is fixed on the side of the sliding ring near the axis of the combing barrel, a brush layer is fixed on the side of the filter layer near the axis of the combing barrel, and a connecting channel is provided on the side of the combing barrel facing the drive structure, and the sliding ring is connected to the drive structure through the connecting channel.

[0016] By adopting the above technical solution, the drive motor drives the drive wheel to rotate through the output shaft. The part of the drive wheel extending to the outside of the drive box meshes or abuts with the sliding ring. After the drive wheel rotates, under the action of tooth meshing or friction, it drives the sliding ring to slide around the circumference in the groove, thereby driving the filter layer and the brush layer to rotate in the combing barrel, so as to achieve the purpose of the brush layer combing the cat hair.

[0017] The invention is further configured such that: a slide rail is fixed to the inner wall of the box, the slide rail extends from the open end of the box toward the side opposite to the open end, a lead screw is provided inside the slide rail, the axial direction of the lead screw is the same as the extension direction of the slide rail, the end of the lead screw is rotatably connected to the inner wall of the box, an adjusting motor that is poweredly connected to the lead screw is fixed to the outer side of the box where the opening is located, and a slider is slidably provided inside the slide rail along the extension direction of the slide rail, the slider is fixedly connected to the outer side of the combing barrel, the slider is penetrated by the lead screw and threadedly connected to the lead screw.

[0018] By adopting the above technical solution, after the motor starts, it drives the lead screw to rotate. At this time, under the action of the threaded connection, the slider slides in the slide rail, thereby driving the combing barrel to adjust along the extension direction of the slide rail, so as to achieve the purpose of adjusting the position of the combing barrel.

[0019] The invention is further configured such that: a limiting groove is provided on the end face of the combing barrel facing the opening of the box; a detachable platform is provided inside the combing barrel; the detachable platform abuts against the inner wall of the combing barrel on the side facing away from the axis of the combing barrel; a limiting block extending into the limiting groove is fixed on the detachable platform; and an active channel for the brush layer to pass through is provided at the connection between the end of the detachable platform along the circumference of the combing barrel and the brush layer; and a cleaning brush abutting against the brush layer is fixed in the active channel.

[0020] By adopting the above technical solution, a detachable platform is installed inside the grooming drum. This prevents the cat from being disturbed by the rotating brush layer when passing through the grooming drum, allowing the cat to pass through normally. Simultaneously, the detachable platform remains stationary during the brush layer's rotation, limited by the interaction of the limiting block and the limiting groove. When the brush layer passes the cleaning brush, the cleaning brush adheres to the attached cat hair, achieving real-time cleaning of the brush layer. When the cleaning brush needs to be replaced or cleaned, the detachable platform is pulled out axially along the grooming drum. At this time, the limiting block slides out of the limiting groove. After removing the detachable platform, the cleaning brush is cleaned or replaced, and the detachable platform is reinserted into the grooming drum, ensuring the limiting block is inserted into the limiting groove. The disassembly and maintenance operation is convenient, reducing the difficulty for users.

[0021] The invention is further configured such that: a vacuum device for extracting gas from inside the box is provided inside the box, the vacuum device including...

[0022] The docking cavity is located on the inner side of the enclosure, opposite to the enclosure opening.

[0023] The adsorption box is fixed to the outer wall of the box body. The interior of the adsorption box is hollow and filled with activated carbon.

[0024] The mandrel extends from one end into the docking cavity and from the other end into the adsorption box.

[0025] The exhaust box is fixed to the outer wall of the enclosure.

[0026] The intermediate tube is connected at one end to the adsorption box and at the other end to the exhaust box.

[0027] An air pump is fixedly installed inside the exhaust box and connected to the intermediate pipe.

[0028] By adopting the above technical solution, after the air pump is started, the gas in the adsorption box is extracted through the intermediate pipe. At this time, the adsorption box generates negative pressure, which causes the gas in the box to enter the adsorption box through the connecting pipe. After the gas in the adsorption box is adsorbed by the activated carbon, the gas enters the air pump in the exhaust box through the intermediate pipe and is discharged. The discharged gas is clean gas, thus achieving the purpose of cleaning the cat hair that has fallen inside the box. This reduces the steps for users to manually maintain the internal environment of the box and improves the convenience of use.

[0029] The present invention is further configured such that: several filter layers are stacked side by side in the exhaust box along the exhaust direction of the air pump.

[0030] By adopting the above technical solution, the gas discharged by the air pump is filtered through the filter core layer before being discharged, further adsorbing harmful substances in the filtered air, ensuring the safety of the discharged gas and not affecting the surrounding environment.

[0031] The invention is further configured such that: a collection cavity is provided inside the combing barrel, an intermediate cavity is provided at the connection between the filter layer and the sliding ring, one end of the intermediate cavity is connected to the collection cavity, an air guide channel is provided inside the collection cavity, and the end of the air guide channel away from the collection cavity is axially aligned with the connecting pipe and can be connected to the connecting pipe.

[0032] By adopting the above technical solution: when the combing barrel moves to the docking cavity through the above process, the connecting pipe extends into the air guide channel and cooperates with the air guide channel. At the same time, during the operation of the above-mentioned air pump, the adsorption box is in a negative pressure state. Since the connecting pipe is connected to the air guide channel and the collecting cavity, the collecting cavity and the air guide channel are also under negative pressure. This allows the gas in the box to pass through the brush layer, be initially filtered by the filter layer, enter the collecting cavity through the intermediate cavity, and then enter the connecting pipe through the air guide channel. After secondary filtration through the above process, it is discharged. This allows large particles of foreign matter, such as cat hair and debris, to be blocked by the filter layer, preventing them from entering the connecting pipe and the adsorption box. This avoids clogging of the collecting cavity, the air guide channel, the connecting pipe, and the adsorption box, thus greatly improving the stability and service life of the collecting cavity, the air guide channel, the connecting pipe, and the adsorption box. Users do not need to clean and replace them frequently, reducing the cumbersome operation for users.

[0033] The invention is further configured such that: an elastic cavity is provided in the inner wall of the docking cavity away from the box opening; a sealing plate is slidably provided in the docking cavity along the axial direction of the combing barrel; the sealing plate is tightly fitted with the inner wall of the docking cavity; a spring is fixed in the inner wall of the elastic cavity away from the docking cavity; and the other end of the spring is fixedly connected to the sealing plate.

[0034] By adopting the above technical solution, when the combing barrel is not connected to the docking cavity, and the connecting pipe is not inserted into the air duct, the sealing plate will close the opening of the docking cavity under the elasticity of the spring, thereby preventing the cat from damaging the opening of the connecting pipe inside the box and protecting the safety of the connecting pipe.

[0035] The invention is further configured such that: a dustproof baffle is provided inside the box to divide the box into sections, and a through channel is provided on the dustproof baffle for the combing drum to pass through, and the dustproof baffle blocks the space between the outer side of the combing drum and the inner side of the box.

[0036] By adopting the above technical solution, the dust baffle can prevent cat hair from entering the space between the combing barrel and the inner wall of the box when the combing barrel is in the opening position of the box, thereby preventing cat hair from entering the drive box and accumulating inside, affecting the rotation of the drive wheel, and extending the maintenance interval of the drive structure.

[0037] The beneficial effects of this invention are:

[0038] 1. The drive structure drives the brush structure to sweep radially along the combing barrel. When the cat enters the combing barrel through the opening of the box, the cat's fur is combed radially by the brush structure. Since cat fur naturally extends from the head to the tail in its normal state, the cat's fur will become messy after being combed horizontally by the brush structure. Because cats are used to licking and grooming their fur after it becomes messy, the cat will curl up and groom itself after entering the box. This helps stabilize the cat's emotions during the process and prevents stress reactions that could lead to sudden death, thus protecting the cat's safety during transport.

[0039] 2. A detachable platform is installed inside the grooming tub to prevent the cat from being disturbed by the rotating brush layer when passing through the grooming tub, allowing the cat to pass through normally. At the same time, the detachable platform remains stationary under the limiting action of the limiting block and limiting groove during the rotation of the brush layer. When the brush layer passes the cleaning brush, the cleaning brush sticks the cat hair attached to the brush layer, achieving the purpose of cleaning the brush layer in real time.

[0048] To facilitate a clear understanding of the technical means, inventive features, objectives, and effects of this invention, the following detailed description is provided. Figure 1-7 The invention will be further illustrated as shown.

[0049] like Figure 1-6 As shown, a pet carrier includes a body 10, a grooming barrel 20, a brush structure, and a drive structure. The body 10 is hollow and has a one-way opening, which is circular. The grooming barrel 20 is located at the opening inside the body 10 and is annular in shape. The outer diameter of the grooming barrel 20 is the same as the opening of the body 10. A groove 21 is formed on the inner side of the grooming barrel 20, and the groove 21 surrounds the grooming barrel 20. The brush structure is located within the groove 21 and rotates along the axial direction of the grooming barrel 20 within the groove 21. The brush structure includes a sliding ring 28 that fits against the bottom wall of the slide groove 21. The sliding ring 28 is annular. A filter layer 29 is fixed to the side of the sliding ring 28 near the axis of the combing barrel 20. A brush layer 27 is fixed to the side of the filter layer 29 near the axis of the combing barrel 20. A connecting channel 22 is provided on the side of the combing barrel 20 facing the drive structure. The sliding ring 28 is connected to the drive structure through the connecting channel 22.

[0050] like Figure 1-5As shown, the drive structure is located inside the housing 10 and is connected to the brush structure, driving the brush structure to rotate. The drive structure includes a drive housing 60, a through channel 61, a drive wheel 62, and a drive motor 15. The drive housing 60 is fixed to the inner wall of the housing 10 and located on the radial side of the combing barrel 20, and is hollow inside. The through channel 61 is formed on the side wall of the drive housing 60 facing the combing barrel 20. The drive motor 15 is fixed to the side wall of the housing 10 with an opening, and has an output shaft that extends into the drive housing 60. The drive motor 15 is surrounded by a first outer protective shell 12 that is fixedly connected to the housing 10. The drive wheel 62 is rotatably mounted inside the drive housing 60. The drive wheel 62 is coaxially mounted and fixedly connected to the output shaft of the drive motor 15. Part of the drive wheel 62 extends from the opening of the through channel 61 to the outside of the drive housing 60 and passes through the connecting channel 22 in the brush structure to connect with the sliding ring 28. The connection method is tooth meshing or abutment. When abutting, there is friction, which allows the drive wheel 62 to drive the sliding ring 28 to rotate.

[0051] When the brush layer 27 in the above-mentioned brush structure rotates, the tangential direction of the rotation direction is the radial direction of the combing barrel 20, so that the cat's hair is combed perpendicular to the cat's movement direction by the combing barrel 20, making the cat's hair messy.

[0052] like Figure 1 , Figure 3 and Figure 7 As shown, a limiting groove 23 is provided on the end face of the combing drum 20 facing the opening of the housing 10. A detachable platform 30 is provided inside the combing drum 20. The side of the detachable platform 30 facing away from the axis of the combing drum 20 abuts against the inner wall of the combing drum 20. A limiting block 32 extending into the limiting groove 23 is fixed on the detachable platform 30. A movable channel 33 for the brush layer 27 to pass through is provided at the connection between the detachable platform 30 and the end of the combing drum 20 along the circumference. A cleaning brush 31 abutting against the brush layer 27 is fixed in the movable channel 33. The detachable platform 30 is detachable. The detachable platform 30 can be removed by moving the detachable platform 30 away from the housing 10 along the axis of the combing drum 20.

[0053] like Figure 3-4As shown, a slide rail 16 is fixed to the inner wall of the housing 10. The slide rail 16 extends from the open end of the housing 10 toward the side opposite to the open end. A lead screw 17 is installed inside the slide rail 16. The axis of the lead screw 17 is the same as the extension direction of the slide rail 16. The end of the lead screw 17 is rotatably connected to the inner wall of the housing 10. An adjusting motor 14, which is powered by the lead screw 17, is fixed to the outer side of the housing 10 where the opening is located. A slider 26 is slidably installed inside the slide rail 16 along the extension direction of the slide rail 16. The slider 26 is fixedly connected to the outer side of the combing barrel 20. The slider 26 is penetrated by the lead screw 17 and threadedly connected to the lead screw 17. A second outer protective shell 13 is installed around the outside of the adjusting motor 14. The second outer protective shell 13 is fixedly connected to the end of the housing 10.

[0054] like Figure 2-5 As shown, the housing 10 is equipped with an extraction device for removing gas from inside the housing 10. The extraction device includes an exhaust box 40, an intermediate pipe 42, an adsorption box 43, a connecting pipe 47, a docking cavity 48, and an extraction pump. The docking cavity 48 is located on the inner side of the housing 10, opposite to the opening of the housing 10. The adsorption box 43 is fixed to the outer side wall of the housing 10. The adsorption box 43 is hollow and filled with activated carbon. One end of the connecting pipe 47 extends into the docking cavity 48, and the other end of the connecting pipe 47 extends into the adsorption box 43. The exhaust box 40 is fixed to the outer side wall of the housing 10. One end of the intermediate pipe 42 is connected to the adsorption box 43, and the other end of the intermediate pipe 42 is connected to the exhaust box 40. The extraction pump is fixedly installed inside the exhaust box 40 and connected to the intermediate pipe 42. Several filter layers 41 are stacked side by side inside the exhaust box 40 along the exhaust direction of the extraction pump. An elastic cavity 44 is formed in the inner wall of the docking cavity 48 away from the opening of the housing 10. A sealing plate 46 is slidably arranged in the docking cavity 48 along the axial direction of the combing barrel 20. The sealing plate 46 is tightly fitted to the inner wall of the docking cavity 48. A spring 45 is fixed to the inner wall of the elastic cavity 44 away from the docking cavity 48. The other end of the spring 45 is fixedly connected to the sealing plate 46. A collecting cavity 51 is formed in the combing barrel 20. An intermediate cavity 50 is formed at the connection between the filter layer 29 and the sliding ring 28. One end of the intermediate cavity 50 is connected to the collecting cavity 51. An air guide channel 52 is formed in the collecting cavity 51. The end of the air guide channel 52 away from the collecting cavity 51 is axially aligned with the connecting pipe 47 and can be connected to the connecting pipe 47.

[0055] like Figure 4As shown, the interior of the housing 10 is equipped with a dustproof baffle 63 for dividing the interior of the housing 10. The dustproof baffle 63 has a through-channel for the grooming drum 20 to pass through. The dustproof baffle 63 blocks the space between the outer side of the grooming drum 20 and the inner side of the housing 10. The dustproof baffle 63 can prevent cat hair from entering the space between the grooming drum 20 and the inner wall of the housing 10 when the grooming drum 20 is in the open position of the housing 10, thereby preventing cat hair from accumulating inside the drive box 60 and affecting the rotation of the drive wheel 62, thus extending the maintenance interval of the drive structure.

[0056] During the transfer of the cat, the cat is herded into the box 10. At this time, the drive structure drives the brush structure to sweep radially along the combing barrel 20. When the cat enters the combing barrel 20 through the opening of the box 10, the cat's fur is combed radially by the brush structure along the combing barrel 20. Since cat fur naturally extends from the head to the tail in its normal state, the cat's fur will become messy after being combed horizontally by the brush structure. Since cats are used to licking and grooming their fur after it becomes messy, the cat will curl up and groom itself after entering the box 10. This attracts the cat's attention and reduces its anxiety in the box 10, thus stabilizing its emotions and preventing stress reactions that could lead to sudden death. This helps protect the cat's safety during the transfer.

[0057] The drive motor 15 drives the drive wheel 62 to rotate through the output shaft. The part of the drive wheel 62 extending to the outside of the drive box 60 engages or abuts with the sliding ring 28. After the drive wheel 62 rotates, under the action of tooth meshing or friction, it drives the sliding ring 28 to slide circumferentially in the sliding groove 21, thereby driving the filter layer 29 and the brush layer 27 to rotate in the combing barrel 20, so as to achieve the purpose of the brush layer 27 combing the cat hair.

[0058] After the adjustment motor 14 starts, it drives the lead screw 17 to rotate. At this time, under the action of the threaded connection, the slider 26 slides in the slide rail 16, thereby driving the combing barrel 20 to be adjusted along the extension direction of the slide rail 16, so as to achieve the purpose of adjusting the position of the combing barrel 20.

[0059] A detachable platform 30 is installed inside the grooming drum 20 to prevent the cat from being disturbed by the rotating brush layer 27 when passing through the grooming drum 20, allowing the cat to pass through normally. Simultaneously, the detachable platform 30 remains stationary during the rotation of the brush layer 27 due to the limiting action of the limiting block 32 and the limiting groove 23. When the brush layer 27 passes the cleaning brush 31, the cleaning brush 31 adheres to the cat hair attached to the brush layer 27, achieving real-time cleaning of the brush layer 27. When the cleaning brush 31 needs to be replaced or cleaned, the detachable platform 30 is pulled out axially along the grooming drum 20. At this time, the limiting block 32 slides out of the limiting groove 23. After removing the detachable platform 30, the cleaning brush 31 is cleaned or replaced, and then the detachable platform 30 is reinserted into the grooming drum 20, ensuring the limiting block 32 is inserted into the limiting groove 23. The disassembly and maintenance operation is convenient, reducing the difficulty of operation for users.

[0060] After the suction pump starts, the gas in the adsorption box 43 is drawn out through the intermediate pipe 42. At this time, the adsorption box 43 generates negative pressure, causing the gas in the box 10 to enter the adsorption box 43 through the connecting pipe 47. After the gas in the adsorption box 43 is adsorbed by the activated carbon, harmful substances and foreign objects are adsorbed, and then the gas is discharged through the intermediate pipe 42 into the suction pump of the exhaust box 40. The discharged gas is clean gas, thus achieving the purpose of cleaning the cat hair that has fallen inside the box 10, reducing the steps of manual maintenance of the internal environment of the box 10 and improving the convenience of use. The gas discharged by the suction pump is then filtered by the filter core layer 41 before being discharged, further adsorbing harmful substances in the filtered air, ensuring that the discharged gas is safe and will not affect the surrounding environment.

[0061] When the combing drum 20 moves to the docking chamber 48 through the above process, the connecting pipe 47 extends into the air guide channel 52 and cooperates with it. Simultaneously, during the operation of the aforementioned air pump, the adsorption box 43 is under negative pressure. Since the connecting pipe 47 is connected to the air guide channel 52 and the collecting chamber 51, the collecting chamber 51 and the air guide channel 52 are also under negative pressure. This allows the gas in the box 10 to pass through the brush layer 27, undergo preliminary filtration through the filter layer 29, enter the collecting chamber 51 through the intermediate chamber 50, and then pass through the air guide channel 58. 2. After entering the connecting pipe 47, the material undergoes secondary filtration through the above process before being discharged. This allows large particles such as cat hair and debris to be blocked by the filter layer 29, preventing them from entering the connecting pipe 47 and the adsorption box 43. This avoids clogging of the collecting chamber 51, the air guiding channel 52, the connecting pipe 47, and the adsorption box 43, thus greatly improving the stability and service life of the collecting chamber 51, the air guiding channel 52, the connecting pipe 47, and the adsorption box 43. It also eliminates the need for frequent cleaning and replacement by the user, reducing the complexity of the user's operation.

[0062] When the combing barrel 20 is not connected to the docking cavity 48, the connecting pipe 47 is not inserted into the air duct 52. At this time, the sealing plate 46 closes the opening of the docking cavity 48 under the elastic action of the spring 45, thereby preventing the cat from damaging the opening of the connecting pipe 47 inside the box 10 and protecting the safety of the connecting pipe 47. When the combing barrel 20 is connected to the docking cavity 48, the sealing plate 46 moves towards the elastic cavity 44 under the pressure of the combing barrel 20, and the spring 45 is compressed. At this time, the connecting pipe 47 is exposed and extends into the air duct 52 for engagement.

[0063] The pet carrier can also be used as a grooming box for other domestic pets such as dogs and rabbits. Since animals other than cats are less likely to actively lick their fur to make it neat, the 27-turn mechanism inside the carrier can comb out any matted fur, thus improving its usability.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
