[0039] In some embodiments, the cat litter box 100 further includes two support arms 20. The litter bin 30 is detachably connected to the two mounting arms 12 of the mounting seat 10 through the support arms 20. Specifically, the two support arms 20 are detachably connected to the two mounting arms 12, respectively, and the litter bin 30 is defined between the two support arms 20, so that the litter bin 30 is rotatably connected to the mounting seat 10.

[0040] The sand bin 30 can have a locked state and an unlocked state. When the sand bin 30 is in an unlocked state, the two support arms 20 are respectively fixedly connected to the two mounting arms 12, and the sand bin 30 is defined between the two support arms 20. When the sand bin 30 is in an unlocked state, the two support arms 20 are respectively disconnected from the fixed connection with the two mounting arms 12, that is, the two support arms 20 are respectively removed from the two mounting arms 12, and the sand bin 30 can be removed from the mounting seat 10. Thus, the problem of scaring the pet due to the rotation of the sand bin 30 relative to the mounting seat 10 when the pet enters and exits the sand collecting chamber 301 is avoided.

[0041] In some embodiments, a plurality of legs 13 are provided at the bottom of the mounting base 10. The legs 13 are used to support the mounting base 10, so that the legs 13 can provide stable support and balance for the cat litter box 100, and at the same time provide sufficient installation space for the setting of the feces collection bin 40, and the structure is compact.

[0042] The first sealing member 51 is configured as an annular structure. The sand bin 30 includes an inner bin wall 3011 and an outer bin wall 3012 disposed opposite to each other.

The pressing rod 523 passes through the through hole 5101 and the mounting hole 303, thereby realizing the fixed connection of the first seal 51 to the sand bin 30. There are two retaining rings 521, and the plurality of pressing blocks 522 are connected between the two retaining rings 521. Of course, in some embodiments, the retaining ring 521 can be provided as one.

[0046] Please refer to Figure 2 and Figure 6 , Figure 6 is Figure 3 a schematic structural view of the second implementation manner of the first seal 51, the pressing member 52 and the locking member 53 of the litter box 100 in

[0047] Specifically, the longitudinal section of the first seal 51 is in a "Ji" - shaped structure. Specifically, the first seal 51 includes a sealing portion 511 and a connecting portion 512 connected to the sealing portion 511. The sealing portion 511 is arched. The connecting portion 512 is bent and connected to the edge of the opening 101 of the sealing portion 511 and extends outward. The pressing member 52 presses and fixes the connecting portion 512 to the sand bin 30 or the mounting base 10. For example, the litter box 100 further includes a locking member 53. The pressing member 52 is fixed to the sand bin 30 or the mounting base 10 through the locking member 53. The connecting portion 512 is provided with a plurality of connecting holes 5120. The pressing member 52 is provided with a plurality of alignment holes 5201 corresponding to the plurality of connecting holes 5120 one by one. Specifically, the locking member 53 sequentially passes through the alignment holes 5201 of the pressing member 52 and the connecting holes 5120 of the connecting portion 512 and is locked to the mounting hole 303 of the sand bin 30.

[0048] In some embodiments, the pressing member 52 may omit the pressing block 522. For example, the pressing member 52 includes two pressing rings 521, the sealing portion 511 is disposed between the two pressing rings 521 and is attached to the sand bin 30 and the mounting seat 10, and the connecting portion 512 is located between the pressing ring 521 and the sand bin 30; or, between the pressing ring 521 and the mounting seat 10. Thus, the sealing portion 511 of the first sealing member 51 is prevented from shifting relative to the sand bin 30 and the mounting seat 10 and the first sealing member 51 is prevented from being deformed excessively, so that the first sealing member 51 can maintain a sealed fit with the sand bin 30 and the mounting seat 10, thereby improving the sealing performance of the first sealing member 51. Of course, in some embodiments, the pressing member 52 may include one pressing ring 521.

[0049] Please also read Figure 2 , Figure 7 and Figure 8 , Figure 7 yes Figure 2 A schematic structural diagram of a waterproof member 61 and a second sealing member 62 of a cat litter box 100; Figure 8 yes Figure 7 Exploded view of the waterproof member 61 and the second sealing member 62 of the cat litter box 100 in FIG. In some embodiments, the cat litter box 100 further includes a waterproof member 61. The waterproof member 61 is disposed in the litter bin 30 and is located at the bottom of the litter bin 30. Thus, the waterproof member 61 can prevent the pet's urine from leaking and soiling the soft rubber pad located below the cat litter box 100, thereby avoiding the problem of difficulty in cleaning the soft rubber pad and the cat litter box 100. The soft rubber pad is placed next to or below the cat litter box 100 to prevent cat litter from being brought out, reduce pollution to the surrounding environment, and keep the environment clean.

[0050] The waterproof member 61 is detachably attached to the inner wall 3011 of the sand bin 30. Thus, on the one hand, the waterproof member 61 is prevented from shifting when the pet excretes in the sand bin 30, so that the waterproof member 61 can maintain a sealed fit with the sand bin 30, thereby improving the waterproof performance of the waterproof member 61; on the other hand, the waterproof member 61 is detachably attached to the inner wall 3011 of the sand bin 30, thereby facilitating operations such as replacement and cleaning of the waterproof member 61.

[0051] For example, in this embodiment, the cat litter box 100 further includes a second sealing member 62, and the edges of the waterproof member 61 are sealed to the inner bin wall 3011 of the litter bin 30 through the second sealing member 62. Thus, on the one hand, the second sealing member 62 can achieve a sealed fit between the waterproof member 61 and the litter bin 30, thereby preventing the pet's urine from leaking from the gap between the waterproof member 61 and the litter bin 30.

[0052] The waterproof member 61 is provided with a positioning structure 611, and the second sealing member 62 is provided with a guide structure 621, which is matched and connected with the positioning structure 611 and fixed on the sand bin 30, thereby facilitating the positioning and assembly of the second sealing member 62 and the waterproof member 61, and improving the assembly efficiency and assembly yield. Specifically, the sand bin 30 is provided with a fixing structure fixedly connected with the guide structure 621, thereby improving the stability and reliability of the connection between the waterproof member 61 and the sand bin 30.

[0053] The hardness of the waterproof member 61 is greater than the hardness of the second sealing member 62. Specifically, the waterproof member 61 can be configured as a hard glue structure. Therefore, the waterproof member 61 is configured as a hard glue structure to resist the erosion and adhesion of urine, microorganisms, etc., and is convenient for cleaning and assembly; on the other hand, the waterproof member 61 has a fixed shape, which improves the stability of storing cat litter. The waterproof member 61 can be configured as but not limited to a basin-shaped structure, a bowl-shaped structure, etc. The second sealing member 62 is configured as a soft glue structure. Therefore, on the one hand, the sealing performance of the second sealing member 62 is improved, and the sealing fit between the waterproof member 61 and the sand bin 30 is ensured; on the other hand, the second sealing member 62 can avoid the problem of the second sealing member 62 scratching the pads on the cat's feet when the cat climbs, and avoid the problem of cutting the hands when the waterproof member 61 is manually disassembled; on the other hand, the soft glue structure also has good shock resistance, shock absorption and noise reduction effects. The material of the soft glue structure includes but is not limited to at least one of polyurethane, polyimide, graphene, polyphenylene sulfide, etc. The material of the soft rubber structure includes but is not limited to at least one of rubber, silicone, thermoplastic elastomer, polyvinyl chloride, etc.

[0054] Please also read Figure 2 , Fig. 9 and Fig.10 , Fig. 9 yes Figure 2 A schematic structural diagram of the first sand filter 71 of the cat litter box 100; Fig.10 yes Figure 2 Schematic diagram of the structure of the second sand filter net 73 of the cat litter box 100 in the cat litter box 100. In some embodiments, the cat litter box 100 further includes a first sand filter net 71 and a second sand filter net 73, the second sand filter net 73 and the first sand filter net 71 are arranged to overlap in the filtering direction, and are used to adjust the mesh size of the first sand filter net 71. Thus, on the one hand, the first sand filter net 71 and the second sand filter net 73 are used to filter cat feces and other debris in the cat litter; on the other hand, the first sand filter net 71 and the second sand filter net 73 are used in combination, so that cat litters of different specifications and coarseness can be filtered, and various cat litters can be used flexibly and conveniently. When there is cat excrement in the cat litter, part of the cat litter is bonded and agglomerated by the cat excrement, and the cat litter needs to be cleaned. The sand bin 30 can rotate relative to the mounting seat 10 under the action of a driving force or an external force, and the clean cat litter is separated from the bonded and agglomerated contaminated cat litter to clean the cat litter in the sand bin 30.

[0055] Exemplarily, in this embodiment, the second sand filter net 73 is detachably fixedly connected to the first sand filter net 71. The first sand filter net 71 includes a first mounting frame 711 and a plurality of first bars 712, and the plurality of first bars 712 are arranged at intervals on the first mounting frame 711. The second sand filter net 73 includes a second mounting frame 731 and a plurality of second bars 732, and the plurality of second bars 732 are arranged at intervals on the second mounting frame 731, and the extension direction of the plurality of second bars 732 is different from the extension direction of the plurality of first bars 712. Thus, when the second sand filter net 73 is removed from the first sand filter net 71, the first sand filter net 71 can filter long strips or larger cat litters; when the second sand filter net 73 is installed on the first sand filter net 71, the first sand filter net 71 cooperates with the second sand filter net 73 to filter granular or smaller cat litters, thereby filtering cat litters of various coarseness and fineness, facilitating the flexible use of various cat litters, and realizing the separation of cat litters and feces, facilitating cleaning operations.

[0056] Specifically, the first sand filter net 71 includes a filter portion 710 and a mounting portion 720. The filter portion 710 is bent and connected to the mounting portion 720. The filter portion 710 is used to filter cat litter. The mounting portion 720 is installed in the sand bin 30. The mounting portion 720 and the filter portion 710 are integrally formed, thereby improving the reliability and stability of the connection between the mounting portion 720 and the filter portion 710 and improving the assembly efficiency. Of course, the mounting portion 720 and the filter portion 710 can be detachably connected, thereby reducing the difficulty of processing the mounting portion 720 and the filter portion 710.

[0057] In some embodiments, the filter part 710 is provided with a fixing part 7101. The second sand filter net 73 is provided with a matching part 7301 that is matched and connected with the fixing part 7101. One of the fixing part 7101 and the matching part 7301 is configured as a connecting sleeve, and the other of the fixing part 7101 and the matching part 7301 is configured as an elastic plug rod that is detachably connected with the connecting sleeve, so as to facilitate the detachable assembly of the first sand filter net 71 and the second sand filter net 73. In some other embodiments, the second sand filter net 73 can be fixed to the sand bin 30; or, the second sand filter net 73 is directly overlapped with the first sand filter net 71. Exemplarily, in this embodiment, the first sand filter net 71 is arranged in contact with the second sand filter net 73. Of course, the first sand filter net 71 and the second sand filter net 73 can also be arranged at intervals.

[0058] The first sand filter 71 and the second sand filter 73 are adapted in appearance, that is, the size of the first sand filter 71 can be equal to the size of the second sand filter 73, so as to facilitate the alignment and assembly of the first sand filter 71 and the second sand filter 73, and the cat litter is filtered through the first sand filter 71 and the second sand filter 73, thereby improving the filtering effect and efficiency of the cat litter. Of course, in some embodiments, the size of the first sand filter 71 can be smaller than or larger than the size of the second sand filter 73, which is not specifically limited in the embodiments of the present application.

[0059] In some embodiments, the second sand filter net 73 is rotatably arranged relative to the first sand filter net 71. Thus, the user can adjust the mesh size of the first sand filter net 71 and the second sand filter net 73 by adjusting the rotation angle of the second sand filter net 73 relative to the first sand filter net 71. When the second sand filter net 73 is rotated to the extension direction of the second grid bar 732 being the same as the extension direction of the first grid bar 712, the first sand filter net 71 and the second sand filter net 73 can still filter long strips or larger cat litter; when the second sand filter net 73 is rotated to the extension direction of the second grid bar 732 being different from the extension direction of the first grid bar 712, the first sand filter net 71 and the second sand filter net 73 can still filter granular or smaller cat litter. The second sand filter net 73 and the first sand filter net 71 can be detachably connected together, or they can be non-detachably connected together.

[0060] In some embodiments, the second sand filter net 73 further includes a plurality of third bars 733, which are arranged at intervals on the second mounting frame 731 and are arranged in a staggered manner with the plurality of second bars 732, and the extension direction of the plurality of third bars 733 is different from the extension direction of the plurality of first bars 712. Thus, the first sand filter net 71 and the second sand filter net 73 cooperate to filter cat litter of smaller size.

[0061] The spacing D between two adjacent first bars 712 is 10mm-15mm. It can be understood that when the spacing D between the first bars 712 is too large, the first filter sand net 71 cannot separate the agglomerated cat litter from the non-agglomerated cat litter well; when the spacing D between the first bars 712 is too small, the non-agglomerated cat litter passes through the mesh of the first filter sand net 71 at a slow speed, thereby reducing the separation efficiency from the agglomerated cat litter. The embodiment of the present application sets the spacing D between the two adjacent first bars 712 in a suitable size, which can not only separate the agglomerated cat litter from the non-agglomerated cat litter well, but also improve the separation efficiency of the agglomerated cat litter from the non-agglomerated cat litter. For example, the spacing D between the first bars 712 can be, but is not limited to, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm, etc. The spacing D between the first bars 712 is only used for detailed description and can be designed according to the size of the cat litter, and the embodiment of the present application is not specifically limited.

[0062] Please also read Figure 2 , Fig.11 and Fig.12 , Fig.11 yes Figure 2 A schematic structural diagram of a first perspective view of a sand retaining plate 80 of a cat litter box 100; Fig.12 yes Figure 2 Schematic diagram of the structure of the sand baffle 80 of the cat litter box 100 from a second perspective. In some embodiments, the cat litter box 100 further includes a sand baffle 80. The sand bin 30 is provided with a sand collecting chamber 301 and a chamber opening 302 connected to the sand collecting chamber 301, the chamber opening 302 is tilted downward, and the sand baffle 80 is located at the bottom edge of the sand bin 30 at the chamber opening 302. Thus, on the one hand, the chamber opening 302 is tilted downward, so that it is convenient for pets to freely enter and exit the sand bin 30; on the other hand, the sand baffle 80 is connected to the bottom edge of the sand bin 30 at the chamber opening 302, so that the setting of the sand baffle 80 can heighten the wall of the sand bin 30 to prevent the pet from digging the cat litter and splashing out of the sand bin 30.

[0063] In some embodiments, the sand shield 80 is detachably connected to the sand bin 30. This facilitates the packaging of the cat litter box 100, reduces transportation costs, facilitates the processing and molding of the cat litter box 100, facilitates the maintenance of the cat litter box 100, and facilitates the user to replace the sand shield 80 of different height specifications, so that the pet can still freely enter and exit the sand bin 30. For example, the sand shield 80 is bonded to the sand bin 30. Specifically, the sand shield 80 and the sand bin 30 can be bonded and connected by Velcro or an adhesive layer. For another example, the sand shield 80 can be installed on the sand bin 30 in a liftable manner. Specifically, the sand shield 80 can be configured as a folding or telescopic structure; or, the installation position of the sand shield 80 relative to the sand bin 30 can be adjusted. Of course, in some embodiments, the sand shield 80 can also be non-detachably connected to the sand bin 30, which is not specifically limited in the embodiments of the present application.

[0064] For example, in this embodiment, a support shell 31 is provided in the sand collecting chamber 301. The support shell 31 is located at the bottom edge of the sand bin 30 at the bin opening 302. The sand baffle 80 is detachably supported on the support shell 31, and the protruding height H of the sand baffle 80 relative to the support shell 31 gradually decreases from the middle to both sides in the circumferential direction of the bin opening 302. Therefore, on the one hand, the setting of the support shell 31 can provide support and installation position for the sand baffle 80, facilitate assembly, and improve the stability and reliability of the sand baffle 80 installed on the sand bin 30; on the other hand, based on the setting that the protruding height H of the sand baffle 80 relative to the support shell 31 gradually decreases from the middle to both sides in the circumferential direction of the bin opening 302, the sand baffle 80 can cover the bottom of the bin opening 302 to reduce the risk of the pet scratching the cat litter and splashing out of the sand bin 30, while ensuring that there is enough space at the top of the bin opening 302 for the pet to freely enter the sand bin 30. The side wall of the support shell 31 facing away from the sand bin 30 is smoothly connected to the inner bin wall 3011 of the sand bin 30, thereby avoiding sanitary dead corners and reducing safety hazards.

[0065] The sand shield 80 includes a blocking portion 81 and an extension portion 82. The extension portion 82 is bent and connected to the bottom of the blocking portion 81 and supported on the support shell 31, and the blocking portion 81 blocks part of the bin opening 302. Therefore, the setting of the extension portion 82 facilitates the alignment and assembly of the sand shield 80 and the support shell 31. The protruding height H of the blocking portion 81 relative to the extension portion 82 gradually decreases from the middle to both sides in the circumferential direction of the bin opening 302, so that the blocking portion 81 can block the bottom of the bin opening 302 to reduce the risk of the pet scratching the cat litter and splashing out of the sand bin 30, while ensuring that there is enough space at the top of the bin opening 302 for the pet to freely enter the sand bin 30.

[0066] For example, in this embodiment, the blocking portion 81 is arranged in an arc shape, thereby softening the sharpness of the sand shield 80, enhancing the sense of extension, improving the visual height, avoiding sanitary blind spots, and reducing safety hazards. The extension portion 82 is arranged to extend toward the outer side of the bend of the blocking portion 81. On the one hand, it prevents cat litter from remaining at the corner where the blocking portion 81 and the extension portion 82 are connected, avoiding sanitary blind spots, reducing the possibility of bacterial growth, and making cleaning more convenient. The end of the blocking portion 81 facing away from the extension portion 82 is provided with a rounded structure 811, thereby preventing the blocking portion 81 from scratching the pads on the cat's feet when the cat climbs, and avoiding the problem of cutting hands when manually removing the sand shield 80.

[0067] In some embodiments, a limiting portion 83 is further provided at the edge of the extension portion 82, and a positioning portion cooperating with the limiting portion 83 is provided at the edge of the port 302 of the sand bin 30, thereby facilitating the positioning and assembly of the sand retaining plate 80 and the sand bin 30, and improving the assembly efficiency and assembly yield. One of the limiting portion 83 and the positioning portion is configured as a groove structure, and the other of the limiting portion 83 and the positioning portion is configured as a protrusion structure cooperating with the groove structure.

[0068] In some embodiments, the extension portion 82 is further provided with an operating portion 84, so that it is convenient for the user to disassemble or assemble the sand deflector 80, thereby improving the user's experience. The operating portion 84 is extended relative to the extension portion 82 toward the side facing away from the blocking portion 81, so that the operating portion 84 can form a gripping position outside the sand bin 30, thereby facilitating the user to disassemble or assemble the sand deflector 80, thereby improving the user's experience.

[0069] The maximum protruding height H of the sand shield 80 relative to the support shell 31 is 4mm-7mm. It can be understood that when the maximum protruding height H of the sand shield 80 relative to the support shell 31 is too large, the pet is blocked from entering and exiting the sand bin 30, which may injure the pet; when the maximum protruding height H of the sand shield 80 relative to the support shell 31 is too small, the cat litter is easy to splash out of the sand bin 30 when the pet digs the cat litter. In the embodiment of the present application, by setting the maximum protruding height H of the sand shield 80 relative to the support shell 31 at an appropriate height size, it can not only reduce the risk of the cat litter splashing out of the sand bin 30 when the pet digs the cat litter, but also ensure that there is enough space at the top of the bin opening 302 for the pet to freely enter the sand bin 30. For example, the maximum protruding height H of the sand shield 80 relative to the support shell 31 can be, but not limited to, 4mm, 5mm, 6mm or 7mm. The maximum protruding height H of the sand shield 80 relative to the support shell 31 is only used for detailed description and can be designed according to the size of the sand bin 30 and the size of the pet, and is not specifically limited in the embodiment of the present application.
