Description

Technical Field

[0001] The utility model relates to the technical field of pet equipment, in particular to a cat litter box. Background Art

[0002] A cat litter box is a toilet product for pet cats and is a tool for conveniently cleaning the excrement of pet cats. Therefore, for people and families who like to keep pet cats, a cat litter box is essential. The structure of traditional cat litter boxes is simple. Basically, a layer of cat litter is laid in the cat litter box. After a pet cat uses the cat litter box, it often needs to be regularly cleaned by the breeder. However, with the frequent use of the cat litter box, even if it is regularly cleaned, there are still odors or stinks in the cat litter box. As the time of the presence of the odor or stink prolongs, there are also odors in the air, which affects people's daily lives.

[0003] The prior art CN220630547U discloses a cat litter box with a deodorizing function, which includes a base, a support at one end of the base, an exhaust system with an exhaust passage, and a suction device. A roller is arranged on the base, the exhaust passage is arranged on the support, the intake end of the exhaust passage is arranged on the side of the support close to the roller, and the outlet end extends to a desired position through an exhaust pipe. The suction device is used to extract the odor in the roller and discharge it along the exhaust passage. An exhaust through-hole is arranged at a position of the roller close to the intake end. Among them, the exhaust system further includes a filtering component, and the filtering component includes one or more of a filter screen, filter cotton and a combination of multiple ones. When specifically arranging the filtering component, the filtering component includes a first filter screen, filter cotton and a second filter screen distributed along the flowing direction of the exhaust passage. During the exhaust deodorization process, the first filter screen prevents sundries doped in the gas from entering the exhaust passage, and the filter cotton is made of a material with bactericidal and odor-removing functions. When using the exhaust system of the prior art, the suction device is started, so that the gas in the roller enters the exhaust pipe through the exhaust through-hole. The odor gas entering the exhaust pipe is deodorized by the filter cotton, and the mixture of cat hair and cat litter dust passing through the exhaust through-hole is blocked by the first filter screen and does not enter the exhaust passage, thereby reducing the possibility of being blocked inside the exhaust passage.

[0004] However, in the prior art, since the first filter screen and the exhaust passage cannot be disassembled and cleaned or replaced at will, during the exhaust deodorization process of the cat litter box, the mixture of cat hair and cat litter dust accumulates at the first filter screen after being blocked by the first filter screen as it flows with the odor gas. As the number of exhaust deodorization times of the cat litter box increases, the mixture of cat hair and cat litter dust gradually accumulates on the first filter screen. As the mixture of cat hair and cat litter dust gradually accumulates, the first filter screen is blocked, and it is difficult for the odor gas to enter the exhaust system from the first filter screen, resulting in a decline or failure of the deodorization performance of the roller. Summary of the Utility Model

[0005] The utility model aims to provide a cat litter box, which solves the problem that the first filter screen cannot be disassembled, and reduces the clogging of the filter component, thereby reducing the deodorizing performance of the drum or causing it to fail, by disassembling the filter component for cleaning.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cat litter box, including a base bracket and a drum, the drum is rotatably arranged on the base bracket, the base bracket is provided with an exhaust and deodorization system and a containing box, the containing box is supported under the drum, the base bracket is provided with an exhaust channel, the exhaust channel is connected to the containing box, and also includes a filtering device, the filtering device includes a mounting frame and a filtering component, the mounting frame is detachably arranged on the base bracket, and the filtering component is arranged on the mounting frame and is located in the exhaust channel.

[0007] After adopting the above technical scheme, the utility model has the following advantages: when using the cat litter box, the cat litter is placed in the drum, and after the pet cat uses the cat litter box, the pet cat's excrement is mixed with the cat litter to form blocks, and when processing the pet cat's excrement, the drum is rotated, and the clean cat litter enters the interlayer of the drum, and the cat litter mixed with the pet cat's excrement rolls out from the opening on the drum and falls into the receiving box, and at the same time, the exhaust deodorization system on the base bracket is turned on, and under the action of the exhaust deodorization system, the odorous gas in the inner cavity of the base bracket and the inner cavity of the drum enters the exhaust deodorization system along the exhaust channel for odor removal. In addition, when people who keep pet cats find that the odor removal effect has decreased, they can remove the detachable mounting frame from the base bracket and clean the cat hair, dust and other impurities located at the filter component to reduce the possibility of the filter component being blocked during the exhaust deodorization process, thereby reducing the possibility of the exhaust deodorization effect of odorous gas being reduced due to the blockage of the filter component; people who keep pets can also regularly remove the mounting frame from the base bracket to clean the cat hair, dust and other impurities at the filter component to reduce the possibility of odorous gas in the cat litter box escaping from the cat litter box and affecting daily life. By disassembling the mounting frame, the filter component can be removed from the exhaust channel to clean the accumulated cat hair, dust and other impurities, reducing the possibility that the filter component is blocked by cat hair, dust and other impurities, resulting in the odorous gas not being able to enter the exhaust deodorization system well during the exhaust deodorization process, thereby causing the drum deodorization performance to decrease or fail.

[0008] Furthermore, the base bracket is provided with a cavity, and the mounting frame is at least partially embedded in the cavity.

[0009] With the foregoing technical solution, when using the exhaust deodorization system, part or all of the mounting brackets are inserted into the concave cavity. When it is necessary to clean impurities such as cat hair and dust at the filter component, the mounting bracket is pulled out of the concave cavity, so that the filter component can be detached from the base bracket for cleaning. Through the insertion of the mounting bracket into the concave cavity, the disassembly difficulty of the mounting bracket is reduced, which is convenient for cleaning impurities such as cat hair and dust accumulated at the filter component, thereby reducing the possibility that the filter component is blocked and affects the exhaust deodorization effect of the odor gas.

[0010] Further, a limiting wall is provided in the concave cavity, and the mounting bracket abuts against the limiting wall along the direction of the roller towards the exhaust deodorization system to position the mounting bracket.

[0011] With the foregoing technical solution, after the mounting bracket is embedded in the concave cavity, through the abutment of the mounting bracket and the limiting wall, the possibility of the mounting bracket deflecting in the concave cavity is reduced, the stability of the embedding of the mounting bracket is improved, the possibility of a gap existing between the side wall of the concave cavity and the mounting bracket is reduced, and the possibility of odor gas carrying impurities such as cat hair and dust entering the exhaust deodorization system from the concave cavity is reduced.

[0012] Further, an arc-shaped supporting surface is provided on the base bracket, the concave cavity is located on the supporting surface, and the mounting bracket is flush with the supporting surface after being embedded in the concave cavity.

[0013] With the foregoing technical solution, the mounting bracket is flush with the supporting surface, which reduces the influence of the mounting bracket protruding from the supporting surface on the installation of the roller and the rotational cleaning of the roller, reduces the mounting bracket being recessed on the supporting surface, resulting in a depression being formed between the supporting surface and the mounting bracket, and reduces the possibility of cat litter rolling down from the roller accumulating on the mounting bracket.

[0014] Further, elastic hooks are provided on the mounting bracket, and the elastic hooks abut against the base bracket to position the mounting bracket.

[0015] With the foregoing technical solution, when the mounting bracket is installed on the base bracket, the elastic hooks undergo elastic deformation and abut against the base bracket, so that the elastic hooks and the base bracket interact with each other, increasing the resistance when the mounting bracket detaches from the base bracket, improving the stability of the mounting bracket set on the base bracket, reducing the possibility of the mounting bracket accidentally detaching from the base bracket during the tilting or shaking of the cat litter box, and further reducing the possibility of the mounting bracket at the filter component detaching from the exhaust passage and causing impurities such as cat hair and dust to enter the exhaust deodorization system. Under the action of the self-elastic force of the elastic hooks, the abutment of the elastic hooks and the base bracket has little influence on the disassembly of the mounting bracket. When disassembling the mounting bracket, only a little force is required, and with the assistance of the elastic deformation, the mounting bracket can also be disassembled relatively easily.

[0016] Further, a clamping groove is provided on the base bracket, and clamping ribs are provided on the groove wall of the clamping groove. One end of the elastic hook is arranged on the mounting bracket and the other end extends towards the exhaust deodorization system. A hook groove is formed at the end of the elastic hook away from the mounting bracket. After the mounting bracket is installed, the elastic hook is hooked on the clamping rib and the clamping rib is located in the hook groove.

[0017] With the foregoing technical solution, when the mounting bracket is installed on the base bracket, the elastic hook gradually approaches the clamping rib along the installation direction of the mounting bracket. The end of the elastic hook where the hook groove is formed gradually hooks the clamping rib until the mounting bracket is installed in place when the clamping rib is located in the hook groove. Through the insertion of the clamping rib and the hook groove on the elastic hook, the stability of the mounting bracket after installation is improved, and the possibility of the elastic hook accidentally detaching from the base bracket is reduced.

[0018] Further, the clamping rib has a first guiding surface and a second guiding surface distributed along the direction of the mounting bracket towards the exhaust deodorization system. During the installation process of the mounting bracket, the elastic hook slides along the first guiding surface and then the clamping rib is inserted into the hook groove after sliding to the second guiding surface. During the disassembly process of the mounting bracket, the elastic hook slides along the second guiding surface and disengages from the clamping rib.

[0019] With the foregoing technical solution, when installing the mounting bracket, the elastic hook is guided by the first guiding surface, reducing the influence of the elastic hook abutting against the clamping rib along the installation direction of the mounting bracket on the installation of the mounting bracket. The elastic hook undergoes elastic deformation and extends to the second guiding surface during the sliding process along the first guiding surface until the clamping rib is inserted into the hook groove, improving the stability of the mounting bracket after installation. When disassembling the mounting bracket, the elastic hook slides along the second guiding surface towards the first guiding surface, facilitating the disengagement of the elastic hook from the clamping rib and thus facilitating the disassembly of the mounting bracket.

[0020] Further, a groove is provided on the side surface of the mounting bracket facing away from the exhaust deodorization system, and a placement hole is provided on the bottom wall of the groove. The filtering component is placed in the placement hole.

[0021] With the foregoing technical solution, the filtering component is placed in the placement hole, and impurities such as cat hair and dust flowing to the filtering component along with the odor gas accumulate in the groove. When disassembling the mounting bracket, the cat hair, dust and other impurities in the groove are not easily detached from the groove and fall on the base bracket when the mounting bracket rubs against the base bracket, reducing the possibility of cat hair, dust and other impurities falling during the disassembly process of the mounting bracket and remaining in the litter box again.

[0022] Further, a plurality of contact ribs are provided on the base bracket, and the plurality of contact ribs are distributed along the direction perpendicular to the direction of the mounting bracket towards the exhaust deodorization system. After the mounting bracket is embedded in the cavity, the side wall of the mounting bracket facing away from the roller is attached to the contact ribs.

[0023] With the foregoing technical solution, after the mounting bracket is installed on the base bracket, the side wall of the mounting bracket facing away from the roller abuts against the contact rib. Through the abutment of the contact rib, the contact area between the mounting bracket and the base bracket is reduced, thereby reducing the frictional force between the mounting bracket and the base bracket, facilitating the removal of the mounting bracket from the base bracket, and further facilitating the removal and cleaning of the filtering component.

[0024] Furthermore, two operation grooves are arranged side by side on the mounting bracket. The operation grooves are used to assist in removing the mounting bracket, and anti-slip strips are arranged on the operation side walls of the two operation grooves.

[0025] With the foregoing technical solution, when removing the mounting bracket, place the finger or the tool for removing the mounting bracket on the operation side wall of the operation groove, which facilitates firmly holding or clamping the mounting bracket when removing the mounting bracket. The anti-slip strips on the operation side wall reduce the possibility of the finger or the tool slipping off the operation side wall, thereby improving the stability of holding or clamping the mounting bracket, and thus reducing the difficulty of removing the mounting bracket.

[0036] The technical solution of the present utility model will be described in detail below with specific embodiments. These specific embodiments can be combined or replaced according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0037] As Figures 1 to 3 shown, the present utility model provides a cat litter box, which includes a base bracket 1 and a roller disposed on the base bracket 1. The roller is rotatably disposed on the base bracket 1; an opening is provided on the roller. When cleaning the cat litter box, the roller is rotated, and the chips to be cleaned fall out from the opening on the roller for easy cleaning; an exhaust and deodorization system 3 and a receiving box 4 are provided on the base bracket 1. The receiving box 4 is located below the roller, and the excrement to be cleaned falling from the roller accumulates in the receiving box 4. An exhaust passage 15 is provided on the base bracket 1, and the exhaust passage 15 communicates with the receiving box 4.

[0038] In this embodiment, the cat litter box further includes a filtering device 2. The filtering device 2 includes a mounting frame 21 and a filtering component 22. The mounting frame 21 is detachably mounted on the base bracket 1. The filtering component 22 is disposed on the mounting frame 21 and is located in the exhaust passage 15. Impurities such as cat hair and dust passing through the exhaust passage 15 are filtered by the filtering component 22, reducing the possibility of impurities such as cat hair and dust entering the exhaust and deodorization system 3.

[0039] As Figure 3As shown, in order to facilitate the disassembly and installation of the mounting bracket 21, a concave cavity 12 is provided on the base bracket 1, and the mounting bracket 21 is fitted into the concave cavity 12. Specifically, part of the mounting bracket 21 can be fitted into the concave cavity, and the other part of the mounting bracket 21 extends into the exhaust passage 15. One part of the mounting bracket 21 is embedded with the base bracket 1, and the other part extends into the exhaust passage 15 of the exhaust deodorization system 3. The filtering component 22 is located on the mounting bracket 21 that extends into the exhaust passage 15 of the exhaust deodorization system 3. When the exhaust deodorization system 3 is turned on to deodorize the odor gas in the litter box as needed or regularly, the exhaust deodorization system 3 drives the odor gas to flow along the exhaust passage 15 towards the exhaust deodorization system 15. During the flow of the odor gas, the filtering component 22 blocks impurities such as cat hair and dust that flow with the odor gas from entering the exhaust deodorization system 3, thereby reducing the influence of cat hair, dust and other impurities inside the exhaust deodorization system 3 on the normal operation of the exhaust deodorization system 3, and the blocked cat hair, dust and other impurities accumulate at the filtering component 22. When the filter holes of the filtering component 22 are blocked due to the gradual accumulation of cat hair, dust and other impurities at the filtering component 22, the mounting bracket 21 is removed from the base bracket 1 and the filtering component 22 is removed together, and the cat hair, dust and other impurities accumulated at the filtering component 22 are cleaned, reducing the decline or failure of the drum deodorization performance caused by the inability of the odor gas to enter the exhaust deodorization system 3 well due to the blockage of the filtering component 22 by cat hair, dust and other impurities during the exhaust deodorization process.

[0040] In order to facilitate the disassembly of the mounting bracket 21 for cleaning the filtering component 22, as Figure 4 shown, an elastic hook 23 is provided on the mounting bracket 21. The elastic hook 23 is located on the side of the mounting bracket 21 facing away from the drum. After the mounting bracket 21 is installed on the base bracket 1, the elastic hook 23 abuts against the base bracket 1. Through the abutment of the elastic hook 23 and the base bracket 1, the mutual acting force between the mounting bracket 21 and the base bracket 1 is increased, reducing the possibility of the mounting bracket 21 accidentally detaching from the base bracket 1 when the litter box is tilted or shaken, and thus reducing the possibility of cat hair, dust and other impurities entering the exhaust deodorization system 3 and affecting the deodorization effect when the mounting bracket 21 detaches from the base bracket 1 when it does not need to be disassembled.

[0041] In order to improve the stability of the elastic hook 23 abutting against the base bracket 1, as Figure 4As shown, a clamping groove 11 is provided on the base bracket 1. One end of the elastic hook 23 is installed on the mounting bracket 21, and the other end extends towards the exhaust deodorization system 3 to form a hook groove 231. A clamping rib 14 is provided on the groove wall of the clamping groove 11. After the mounting bracket 21 is installed on the base bracket 1, the elastic hook 23 abuts against the clamping rib 14 and the clamping rib 14 is located in the hook groove 231. Through the insertion of the clamping rib 14 into the hook groove 231, the possibility of the elastic hook 23 accidentally detaching from the base bracket 1 is reduced. In addition, by providing the clamping groove 11 and the clamping rib 14 on the base bracket 1, when the elastic hook 23 abuts against the clamping rib 14, a slight collision occurs between the elastic hook 23 and the clamping rib 14 under the action of the elastic force of the elastic hook 23, so that the mounting bracket 21 can receive an appropriate feedback signal during the installation process, facilitating the auxiliary judgment of whether the mounting bracket 21 is installed in place according to whether the feedback signal is received when installing the mounting bracket 21, and further facilitating the judgment of whether the mounting bracket 21 is installed in place.

[0042] As Figure 4 shown, specifically, the clamping rib 14 has a first guiding surface 141 and a second guiding surface 142 distributed along the direction of the mounting bracket 21 towards the exhaust deodorization system 3. The notch of the hook groove 231 faces the clamping groove 11. During the installation process of the mounting bracket 21, the elastic hook 23 undergoes elastic deformation during the guiding sliding along the first guiding surface 141. The guiding of the first guiding surface 141 reduces the influence of the elastic hook 23 abutting against the clamping rib 14 on the installation of the mounting bracket 21. As the mounting bracket 21 is installed, the elastic hook 23 slides to abut against the second guiding surface 142. After the elastic hook 23 hooks the clamping rib 14 and the clamping rib 14 is located in the hook groove 231, the mounting bracket 21 is installed in place. The elastically deformed elastic hook 23 abuts against the second guiding surface 142, reducing the possibility of the mounting bracket 21 accidentally detaching from the base bracket 1; when disassembling the mounting bracket 21, pulling the mounting bracket 21 drives the elastic hook 23 to slide along the second guiding surface 142 to the first guiding surface 141. Through the guiding of the second guiding surface 142, it is convenient for the elastic hook 23 to disengage from the clamping rib 14 so that the hook groove 231 and the clamping rib 14 are disengaged and unlocked, thus facilitating the disassembly of the mounting bracket 21.

[0043] To improve the stability of the mounting bracket 21 inserted into the cavity 12, as Figure 3As shown in the figure, a limiting wall 13 is provided on the concave cavity 12. The limiting wall 13 is located on the side of the concave cavity 12 away from the roller and between the base bracket 1 and the exhaust deodorization system 3. After the mounting bracket 21 is inserted into the concave cavity 12, the mounting bracket 21 abuts against the limiting wall 13 to improve the stability of the mounting bracket 21, and reduce the possibility that the mounting bracket 21 deflects under the action of gravity at its end away from the roller, resulting in a gap between the concave cavity 12 and the mounting bracket 21, so that the odor gas with impurities such as cat hair and dust enters the interior of the exhaust deodorization system 3 from the concave cavity 12. In addition, the limiting wall 13 reduces the gap at the position where the concave cavity 12 is close to the exhaust deodorization system 3, and reduces the possibility that impurities such as cat hair and dust enter the interior of the exhaust deodorization system 3 from the concave cavity 12 after the mounting bracket 21 is removed. In addition, the mounting bracket 21 abuts against the limiting wall 13, reducing the possibility that the mounting bracket 21 extends excessively into the concave cavity 12 and causes the mounting bracket 21 to be sunken.

[0044] To facilitate the installation of the mounting bracket 21, as Figure 6 shown, a plurality of contact ribs 121 are provided on the base bracket 1. The contact ribs 121 are located on the inner wall of the concave cavity 12 and the plurality of contact ribs 121 are distributed along the direction perpendicular to the direction in which the mounting bracket 21 faces the exhaust deodorization system 3. When the mounting bracket 21 is embedded in the concave cavity 12, it slides along the contact ribs 121 until the side wall of the mounting bracket 21 facing away from the roller fits with the contact ribs 121. Through the arrangement of the contact ribs 121, the friction between the mounting bracket 21 and the inner wall of the concave cavity 12 is reduced, thereby facilitating the installation and disassembly of the mounting bracket 21.

[0045] To prevent the possible accumulation of cat litter or the excrement of pet cats on the mounting bracket 21, as Figure 1 and Figure 3 shown, an arc-shaped support surface 16 is provided on the base bracket 1. The support surface 16 is parallel to the outer wall of the roller. The roller is rotatably arranged on the base bracket 1 and is suspended from the support surface 16. After the mounting bracket 21 is installed on the base bracket 1, the side wall of the mounting bracket 21 facing the roller is flush with the inner wall of the support surface 16. Through the flush arrangement, the slope of the side wall of the mounting bracket 21 is the same as that of the support surface 16, reducing the influence of the protrusion of the mounting bracket 21 from the support surface 16 on the rotation of the roller. In addition, when cat litter or the excrement of pet cats falls on the mounting bracket 21, it slides down along the slope on the mounting bracket 21 to the lower end of the base bracket 1, facilitating regular cleaning. And the flush arrangement makes the mounting bracket 21 neither protrude nor sink between the inner walls of the base bracket 1, reducing the possibility that cat litter or the excrement of pet cats accumulates on the mounting bracket 21 or in the gap between the mounting bracket 21 and the base bracket 1, which affects the disassembly of the mounting bracket 21.

[0046] To facilitate the disassembly of the mounting bracket 21, as Figure 6As shown in the figure, two operation grooves 24 are arranged side by side on the side wall of the mounting bracket 21 facing the roller. The operation grooves 24 are used to assist in disassembling the mounting bracket 21. One side wall of each of the two operation grooves 24 serves as an operation side wall 241 when disassembling the mounting bracket 21. The two operation side walls 241 are the side walls that are close to each other and parallel in the two operation grooves 24. When disassembling the mounting bracket 21, the fingers of the installer or the disassembly tool used act on the operation side wall 241. The setting of the operation grooves 24 facilitates a more stable grip or clamping of the mounting bracket 21 during disassembly and installation. To avoid the possibility of the mounting bracket 21 slipping during the disassembly process, anti-slip strips 242 are provided on the operation side wall 241 to increase the roughness of the operation side wall 241. When the fingers or the disassembly tool act on the operation side wall 241, the increased frictional resistance is used to improve the stability of the gripped or clamped mounting bracket 21 and reduce the possibility of the mounting bracket 21 slipping off the fingers or the disassembly tool.

[0047] To reduce the possibility that impurities such as cat hair and dust on the filtering component 22 fall into the litter box under the rubbing between the mounting bracket 21 and the base bracket 1 during the disassembly of the mounting bracket 21, as Figure 7 shown, a groove 26 is provided on the side wall of the mounting bracket 21 facing away from the exhaust and deodorization system 3. A placement hole 211 is provided on the bottom wall of the groove 26. The filtering component 22 is placed in the placement hole 211. Impurities such as cat hair and dust carried in the odor gas accumulate on the groove wall of the groove 26 at the filtering component 22. When disassembling the mounting bracket 21, the groove wall of the groove 26 does not come into contact with the base bracket 1 and no rubbing occurs, thereby reducing the possibility that impurities such as cat hair and dust in the groove 26 fall into the litter box again due to rubbing during the disassembly process of the mounting bracket 21.

[0048] To facilitate the identification of the disassembly direction of the mounting bracket 21, a disassembly mark 25 is provided on the side wall of the mounting bracket 21 facing the roller. The direction indicated by the arrow of the disassembly mark 25 is the disassembly direction of the mounting bracket 21. When disassembling the mounting bracket 21, pull the mounting bracket 21 in the direction indicated by the disassembly mark 25 to reduce the disassembly efficiency of the mounting bracket 21 due to unclear disassembly direction.

[0049] In this embodiment, as Figure 2 shown, the exhaust and deodorization system 3 includes an exhaust fan 31 and a deodorization catalyst 32. The deodorization catalyst 32 is connected to the air outlet end of the exhaust fan 31. The air inlet of the exhaust fan 31 faces the filtering component 22. The odor gas filtered by the filtering component 22 for impurities such as cat hair and dust enters the exhaust fan 31 and is transported to the deodorization catalyst 32 for deodorization, thereby reducing the possibility of odor escaping from the litter box.

[0050] In addition to the above preferred embodiments, there are other implementation manners for the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection claimed by the present utility model.
