[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] An embodiment of the present application provides a pet toilet, which includes a basin body 11 and a cleaning rake 21, wherein the basin body 11 is divided into a first mounting groove 111 and a second mounting groove 112 by a partition 110, the first mounting groove 111 correspondingly forming a sand box for holding pet litter, and the first mounting groove 111 correspondingly forming a garbage box for collecting pet litter blocks, and the cleaning rake 21 can reciprocate relative to the basin body 11 to clean and push the pet litter blocks agglomerated in the sand box into the garbage box through the cleaning rake 21.

[0038] In order to provide driving force for the moving parts such as the cleaning rake 21 in the pet litter box, the pet litter box can be equipped with driving parts such as motors to provide power drive.

[0039] In addition, in the embodiments provided in the present application, improvements are made to the design of the basin body 11, the cleaning rake 21 and other related components, which will be described below with reference to the accompanying drawings.

[0040] In the first embodiment, the cleaning rake 21 needs to move back and forth on the basin 11 to clean and push the pet litter blocks in the litter box into the trash box, in order to improve the cleaning efficiency of the cleaning rake 21.

[0041] The pet litter box in this embodiment includes a cleaning assembly 2, which includes: a cleaning rake 21, a motion module 22, and a guide rail module 23;

[0042] The cleaning rake 21 includes a mounting seat 211 and a rake body 212. The mounting seat 211 is provided with a sliding guide portion 2111, and the rake body 212 is provided with a sliding portion 2121 and a guide portion 2122. The sliding portion 2121 is provided on the sliding guide portion 2111, and the sliding guide portion 2111 is configured to guide the rake body 212 to slide up and down relative to the mounting seat 211; the lower edge of the rake body 212 is provided with a comb tooth structure.

[0043] The motion module 22 includes a mounting frame 221 and a moving component 222. The moving component 222 can slide back and forth on the mounting frame 221. The guide rail module 23 has a guide surface 230. The guide surface 230 extends obliquely from bottom to top along the forward moving direction of the moving component 222.

[0044] The mounting seat 211 is disposed on the moving component 222 , the guide rail module 23 is disposed on the mounting frame 221 , and the guide surface 230 is configured to contact and cooperate with the guide portion 2122 to drive the rake body 212 to move upward relative to the mounting seat 211 .

[0045] Specifically, the cleaning rake 21 is driven to reciprocate along the guide rail module 23 by the moving component 222 in the motion module 22. The cleaning rake 21 adopts a split design, which includes a mounting base 211 and a rake body 212. The rake body 212 is assembled to the mounting base 211 through the cooperation of the sliding part 2121 and the sliding guide part 2111.

[0046] During use, the moving component 222 in the motion module 22 drives the mounting base 211 to reciprocate within the basin 11. During the cleaning process, the moving component 222 drives the mounting base 211 toward the trash can, thereby driving the rake body 212 to comb the litter in the litter box and move the clumped pet litter toward the trash can. After the rake body 212 moves close to the guide surface 230, the guide portion 2122 abuts against the guide surface 230. As the rake body 212 continues to move toward the trash can, the guide surface 230 cooperates with the guide portion 2122 to cause the rake body 212 to move upward, reliably pushing the pet litter into the trash can.

[0047] At the same time, the upward movement of the rake body 212 can more effectively push the pet litter blocks pushed by the rake body 212 into the trash box. At the same time, the pet litter blocks can fall off the rake body 212 into the trash box after the rake body 212 is lifted. In this way, when the rake body 212 moves in the reverse direction, the rake body 212 can reduce the amount of pet litter blocks pushed back into the litter box away from the trash box, thereby improving cleaning efficiency.

[0048] By arranging the rake body 212 on the mounting seat 211 so as to slide up and down, during use, the rake body 212 moves back and forth between the garbage box and the sand box in the basin body 11. During the cleaning process, the moving part 222 drives the cleaning rake 21 to move on the mounting frame 221, so as to push the pet litter in the sand box into the garbage box through the rake body 212. When moving to the garbage box, the guide surface 230 cooperates with the guide part 2122 to enable the rake body 212 to slide upward relative to the mounting seat 211, thereby effectively pushing the pet litter into the garbage box, thereby reducing the possibility of the pet litter being brought back into the sand box by the cleaning rake 21 when the moving part 222 moves in the opposite direction due to incomplete pushing of the pet litter, thereby improving the cleaning efficiency and enhancing the user experience.

[0049] In another embodiment of the present application, the guide rail module 23 includes a first guide rail 231, a second guide rail 232 and a third guide rail 233. The second guide rail 232 is arranged at intervals from the first guide rail 231. The guide surface 230 is provided at the end of the second guide rail 232 opposite to the first guide rail 231. The third guide rail 233 is rotatably provided on the first guide rail 231 and is located between the first guide rail 231 and the second guide rail 232. The third guide rail 233 overlaps the guide surface 230.

[0050] Specifically, in order to reduce the reverse push of the pet litter in the litter box by the rake body 212 during the reverse movement and reset of the mounting base 211 by the movable member 222, thereby more effectively preventing the reverse push of the pet litter lumps remaining in the litter box, the guide rail module 23 is configured with a first guide rail 231, a second guide rail 232, and a third guide rail 233. The third guide rail 233 is located between the first guide rail 231 and the second guide rail 232 and is rotatable relative to the first guide rail 231.

[0051] During use, the moving component 222 drives the mounting base 211 to move back and forth.

[0052] When the moving member 222 drives the mounting seat 211 to move in the first direction, the guide portion 2122 moves onto the guide surface 230 and abuts against the guide surface 230 to drive the rake body 212 to move upward. The guide portion 2122 pushes the third guide rail 233 upward and moves onto the upper surface of the second guide rail 232.

[0053] Specifically, when the movable member 222 drives the mounting base 211 toward the trash bin, i.e., in the first direction, the guide portion 2122 moves toward the guide surface 230. The guide portion 2122 abuts against the guide surface 230 and continues to move, thereby driving the rake body 212 to rise. As the guide portion 2122 continues to move on the guide surface 230, the guide portion 2122 pushes away from the third guide rail 233 and eventually slides to the upper surface of the second guide rail 232. During this process, the third guide rail 233 rotates open and, after disengaging from the guide portion 2122, rotates in the opposite direction due to gravity and re-engages with the guide surface 230.

[0054] After the moving member 222 moves to its position along the first direction, the guide portion 2122 moves to the upper surface of the second guide rail 232 . At this time, the rake body 212 is lifted relative to the mounting seat 211 and rises out of the sand box.

[0055] like Figure 2 As shown, when the movable member 222 drives the mounting seat 211 to move along the second direction, the guide portion 2122 slides on the upper surface of the second guide rail 232, the upper surface of the third guide rail 233, and the upper surface of the first guide rail 231 in sequence; after the guide portion 2122 disengages from the upper surface of the first guide rail 231, the rake body 212 slides downward relative to the mounting seat 211 to reset; wherein, the first direction and the second direction are opposite.

[0056] Specifically, when the moving member 222 drives the mounting seat 211 to move away from the trash box, that is, along the second direction, the guide portion 2122 will slide on the upper surfaces of the second guide rail 232, the third guide rail 233 and the first guide rail 231, and after the moving member 222 moves into position along the second direction, the guide portion 2122 disengages from the first guide rail 231, and the rake body 212 moves downward relative to the mounting seat 211 under the action of its own gravity and finally returns to its original position.

[0057] During the reset process of the movable member 222 in the second direction, the rake body 212 rises and leaves the litter box, thereby preventing the rake body 212 from pushing the pet litter in the litter box in the opposite direction, thereby preventing the remaining pet litter lumps from being pushed in the opposite direction by the rake body 212, and thus improving the cleaning efficiency more effectively.

[0058] Moreover, when the moving member 222 moves in the reverse direction along the second direction, since the lower end of the rake body 212 is separated from the pet litter in the litter box, the movement resistance is small and the movement is smoother. In addition, the amount of damage to the pet litter caused by the reverse movement of the rake body 212 is reduced, which is more conducive to improving the user experience.

[0059] In another embodiment, the bottom of the mounting frame 221 is further provided with an inner folding edge 2211 , and the inner folding edge 2211 is arranged below the guide rail module 23 ;

[0060] After the guide portion 2122 is separated from the upper surface of the first guide rail 231 , the guide portion 2122 abuts against the inner folded edge 2211 .

[0061] Specifically, when the moving component 222 drives the mounting seat 211 to move along the first direction, the guide portion 2122 will be supported by the inner folding edge 2211 , and the guide portion 2122 will be guided by the inner folding edge 2211 to ensure smooth movement.

[0062] In another embodiment of the present application, the guide rail modules 23 are respectively provided on both sides of the mounting frame 221, wherein the first guide rail 231 of one of the guide rail modules 23 is provided with a rack structure 2311, and the rack structure 2311 extends along the length direction of the first guide rail 231;

[0063] The sliding portion 2121 can also reciprocate laterally on the sliding guide portion 2111. The mounting seat 211 and the rake body 212 are provided with a protruding structure 2123 on the side of the rake body 212 that cooperates with the rack structure 2311.

[0064] The rack structure 2311 is configured to abut against the protruding structure 2123 to drive the rake body 212 to rock laterally on the mounting base 211 .

[0065] Specifically, to improve the smooth movement of the cleaning rake 21, particularly during movement in the first direction, the rake body 212 is required to clean and move the accumulated pet litter clumps within the litter box. The pet litter clumps may be obstructed by the pet litter during movement. Therefore, during movement of the cleaning rake 21, the protrusions 2123 on the rake body 212 cooperate with the teeth of the rack structure 2311 on the first guide rail 231 to allow the rake body 212 to oscillate laterally relative to the mounting base 211. The varying oscillation of the rake body 212 during movement in the first direction promotes the smooth movement of the accumulated pet litter clumps within the litter box, thereby improving the smoothness of the device's operation and reducing the risk of the device becoming stuck due to larger pet litter clumps being blocked by the pet litter, thereby enhancing operational reliability.

[0066] In one embodiment, the sliding guide portion 2111 cooperates with the sliding portion 2121 to meet the requirements of the rake body 212 moving up and down and shaking left and right. To this end, a guide groove can be opened on the surface of the mounting seat 211, and the guide groove forms the sliding guide portion 2111; the guide groove is arranged vertically, and the cross section of the guide groove is an L-shaped structure; the sliding portion 2121 is an insertion strip provided on the rake body 212, and the cross section of the insertion strip is an L-shaped structure.

[0067] Specifically, the sliding guide portion 2111 adopts an L-shaped guide groove, and the sliding portion 2121 adopts an L-shaped inserting strip. The inserting strip can slide up and down in the guide groove, and can also swing left and right in the guide groove.

[0068] In another embodiment, in order to drive the movable part 222 to move back and forth, two synchronous wheels are respectively provided on both sides of the mounting frame 221, and a synchronous belt 223 is provided on the two synchronous wheels located on the same side of the mounting frame 221. A synchronous shaft is provided between the two synchronous wheels arranged opposite to each other, and the movable part 222 is provided on the synchronous belt 223.

[0069] Specifically, a synchronous belt 223 is used to drive the movable member 222 to move back and forth, and the mounting seat 211 is located between the synchronous belts 223 on both sides. The synchronous belts 223 on both sides drive the movable member 222 to move, so that the cleaning rake 21 can reliably and smoothly reciprocate.

[0070] The moving component 222 may be a mounting block fixed on the synchronous belt 223 , and the mounting seat 211 is fixed between the two mounting blocks.

[0071] In addition, the power of the synchronous shaft can be provided by a motor fixed on the mounting frame 221, or by a motor provided independently of the mounting frame 221, and there is no limitation here.

[0072] In the second embodiment, the basin 11 has a sand box and a garbage box formed inside, and the garbage box is used to collect the agglomerated pet litter blocks. In order to realize the automatic processing of the agglomerated pet litter blocks, the pet toilet is additionally equipped with a crushing component 4.

[0073] The pet toilet includes a litter box assembly 1 and a crushing assembly 4, which are assembled together to form a litter box module.

[0074] The sand basin assembly 1 includes a basin body 11, a filter rack 12, and a collection bin 13. A partition 110 is provided in the basin body 11, dividing the basin body 11 into a first mounting groove 111 and a second mounting groove 112. The filter rack 12 is disposed in the first mounting groove 111 to form a sand box, and the collection bin 13 is disposed in the second mounting groove 112 to form a trash bin. A sewage pipe (not shown) is provided on the basin body 11.

[0075] The crushing assembly 4 includes a crushing knife 41 and a knife shaft 42. The crushing knife 41 is arranged on the knife shaft 42. The knife shaft 42 is rotatably arranged on the collection bin 13. The crushing knife 41 is located at the bottom of the collection bin 13. The bottom of the collection bin 13 is also provided with a sewage outlet 130, which is connected to the sewage pipe.

[0076] Specifically, the filter rack 12 is used to hold pet litter. After the pet defecates in the pet litter in the filter rack 12 , pet agglomerates are formed. The pet agglomerates can be cleaned into the collection bin 13 by the cleaning rake 21 .

[0077] As for the pet lumps collected in the collection bin 13 , the pulverizing blade 41 can be driven to rotate by the blade shaft 42 to break the pet lumps by the pulverizing blade 41 , and the broken pet lumps can be automatically discharged through the sewage outlet 130 .

[0078] By setting a collection bin 13 in the second mounting groove 112 of the basin body 11 and setting a crushing assembly 4 in the collection bin 13, the crushing blade 41 in the crushing assembly 4 is driven by the blade shaft 42 to rotate and crush in the collection bin 13. In this way, the pet litter blocks entering the collection bin 13 can be crushed by the crushing blade 41 at the bottom. The crushed pet litter blocks can be discharged from the sewage outlet 130 at the bottom of the collection bin 13, thereby realizing automatic cleaning of the pet litter blocks in the collection bin 13 to improve the user experience.

[0079] In one embodiment, a spiral blade 43 is further provided on the blade shaft 42 , and the spiral blade 43 is arranged above the crushing blade 41 .

[0080] Specifically, for the pet agglomerates pushed into the collecting bin 13 , under the rotation of the cutter shaft 42 , a spiral blade 43 can squeeze the pet agglomerates and transport them to the crushing knife 41 at the bottom, so that the crushing knife 41 can effectively crush the pet agglomerates.

[0081] In another embodiment, the collecting bin 13 includes a collecting trough 131 and a discharge channel 132, the collecting trough 131 is arranged at the top of the discharge channel 132, the discharge channel 132 is arranged vertically, and the bottom of the discharge channel 132 is provided with the sewage outlet 130; the spiral blade 43 and the crushing knife 41 are located in the discharge channel 132.

[0082] Specifically, the top collection trough 131 has a relatively large opening that matches the width of the filter frame 12. This allows pet clumps pushed onto the filter frame 12 by the cleaning rake 21 to be collected in the collection trough 131. The discharge channel 132 cooperates with the spiral blades 43 to squeeze and convey the pet clumps. Furthermore, the discharge channel 132 cooperates with the crushing blade 41 to break up and disperse the pet clumps.

[0083] The inner wall of the discharge channel 132 is provided with a first annular baffle 133 , and the crushing blade 41 and the sewage outlet 130 are located below the first annular baffle 133 .

[0084] Specifically, the first annular baffle 133 restricts the upward movement of the pet agglomerates during the process of the crushing blade 41 crushing the pet agglomerates, thereby improving the crushing efficiency.

[0085] In addition, a second annular baffle 134 is provided on the inner wall of the discharge channel 132 . The second annular baffle 134 is located above the first annular baffle 133 . The spiral blade 43 passes through the second annular baffle 134 and the first annular baffle 133 in sequence.

[0086] Specifically, the second annular baffle 134 can cooperate with the spiral blade 43 to reliably transport the pet agglomerates to the bottom of the first annular baffle 133 for crushing.

[0088] Specifically, to clean the pet litter on the filter frame 12, the basin body 11 is provided with a first water inlet pipe 113. This pipe allows water to be supplied to the first mounting groove 111 to clean the pet litter. To improve water utilization, used water in the first mounting groove 111 can enter the discharge channel 132 via the water inlet 135, effectively removing any broken-up pet litter clumps within the discharge channel 132. A drain pipe is externally connected to the basin body 11, connecting to the drain port 130. Water, mixed with broken-up pet litter clumps, is then discharged from the drain pipe to the exterior of the basin body 11.

[0089] In another embodiment, a second water inlet pipe 114 is provided on the basin body 11 , a flushing port 136 is provided on the side wall of the collecting tank 131 , and the second water inlet pipe 114 is connected to the flushing port 136 .

[0090] Specifically, in order to clean the surface of the collecting tank 131 , water introduced through the second water inlet pipe 114 may enter the collecting tank 131 through the flushing port 136 to clean the surface.

[0091] In another embodiment of the present application, the sand basin module may further include the cleaning component 2 of the above-mentioned embodiment 1.
