[0032] In the figures, structurally similar elements are denoted by the same reference numerals.

[0033] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, nor as limiting the order of precedence.

[0034] The utility model provides a cat litter box, comprising a shell 11, a litter box 12 located inside the shell 11 for pet defecation, a feces collection device 14 located inside the shell 11 and above the litter box 12 for collecting pet feces in the litter box 12, and a packing device 13 located on one side of the litter box 12 for holding and packing pet feces. The shell 11 includes an inner shell 112 and an outer cover 111 located above the litter box 12. The feces collection device 14 includes a feces collection component symmetrically connected to the inner side of the inner shell and a feces collection component connected between the inner shell 112 and the outer cover 111 for driving the feces collection component. The driving assembly rotates, and opposite sensing members are provided on both sides of the lower part of the inner shell 112. The sensing members include a first sensor 1121 and a second sensor 1124. The feces collection assembly is used to block the first sensor 1121 or the second sensor 1124 so that the first sensor 1121 or the second sensor 1124 can receive the sensing signal. The distance between the first sensor 1121 and the second sensor 1124 is greater than the width of the feces collection assembly. The shell 11 is used to install the litter box 12, the feces collection device 14, and the packing device 13. The litter box 12 is used for pets. The excrement collecting device 14 is used to collect the pet excrement in the litter box 12 and move it to the packing device 13. The packing device 13 is used to pack the pet excrement without manual cleaning. The sensor is used to sense whether there is a pet in the litter box 12. When there is a pet in the litter box 12, the excrement collecting component 14 stops rotating to facilitate the pet's defecation. When the pet excrement is packed and collected, first, the driving component drives the excrement collecting component to rotate, and the excrement collecting component rotates in the inner shell 112. When the excrement collecting component passes through the litter box 12, the excrement collecting component drives the litter box 12 to move. At the same time, due to the action of the sensing part and the width of the feces collection component is smaller than the distance between the first sensor 1121 and the second sensor 1124, when the feces collection component blocks the first sensor 1121 or the second sensor 1124 alone, the driving component operates normally. When the pet enters the litter box, due to the large size of the pet, when the pet blocks the first sensor 1121 and the second sensor 1124 at the same time, the driving component stops working to prevent the feces collection device 14 from scaring the pet, making it safer for the pet to defecate in the litter box.

[0035] The feces collection component includes a swing arm 142 symmetrically connected to both sides of the inner wall of the inner shell 112 and a raking net 143 with both ends respectively connected to the swing arm 142. The swing arm 142 is used to block the first sensor 1121 or the second sensor 1124 so that the first sensor 1121 or the second sensor 1124 can receive the sensing signal. The width of the swing arm 142 is smaller than the distance between the first sensor 1121 and the second sensor 1124 to prevent the swing arm 142 from blocking the first sensor 1121 or the second sensor 1124 at the same time when rotating, thereby preventing the sensing component from misjudging.

[0036] The drive assembly includes a motor 144 connected to the bottom of the inner shell 112 and close to the side of the packing device 13, and a rotating rod 145 laterally connected to the motor 144 and engaged with the motor 144. The two ends of the rotating rod 145 are respectively connected to the swing arm 142. The motor 144 is used to drive the rotating rod 145 to rotate, and the two ends of the rotating rod 145 are used to simultaneously drive the swing arm 142 to rotate, so that the swing arm 142 can drive the rake net 143 to clean up pet feces.

[0037] The drive assembly also includes a synchronous belt 146 and a first synchronous wheel 147 respectively connected to the two ends of the rotating rod 145. A second synchronous wheel 148 is provided at one end of the swing arm 142. The second synchronous wheel 148 extends to the outside of the inner shell 112. The first synchronous wheel 147 and the second synchronous wheel 148 are both connected to the synchronous belt 146. The first synchronous wheel 147 drives the second synchronous wheel 148 to rotate through the synchronous belt 146, so that the symmetrically arranged swing arms 142 can rotate synchronously, which can effectively prevent the harrow net 143 from being on the same horizontal line and prevent the feces on the harrow net 143 from leaking.

[0038] There are multiple sensing parts, which are located on both sides of the swing arm 142. The multiple sensing parts are used to sense and monitor the shape of the litter box 12 in all directions, preventing smaller pets from walking into the blind spots of the sensing parts to defecate, thereby further ensuring the safety of the pets.

[0039] Please refer to Figures 5, 6 and 7. Figure 5 is a three-dimensional view of the feces collection device of the cat litter box of the present invention, Figure 6 is a top view of the swing arm of the cat litter box of the present invention, and Figure 7 is a sectional view taken along the cutting line BB in Figure 6. The swing arm 142 is provided with a through groove located in the swing arm 142 and extending along the length direction of the swing arm 142, a mounting groove located on one side of the swing arm 142 and communicating with the through groove, and a limiting member 149 connected to the mounting groove for limiting the raking net 143. Both ends of the raking net 143 are provided with a mounting frame 1431 extending into the through groove and located behind the limiting member 149. The through groove is used to place the mounting frame 1431, and the mounting groove is used to place the limiting member 149. The limiting member 149 is used to limit the mounting frame 1431, thereby fixing the mounting frame 1431 of the raking net 143 on the swing arm 142.

[0040] A fixing groove is also provided on one side of the swing arm 142, and the fixing groove is communicated with the mounting groove. The limiting member 149 includes a fixing plate 1491, a rotating shaft located on both sides of the fixing plate 1491, a button 1493 located at the top of one end of the fixing plate 1491, a spring 1494 located below the button 1493 and in the fixing groove, and a stopper 1492 located below the other end of the fixing plate 1491 and used to clamp the mounting bracket 1431. The fixing groove is used to place the spring 1494. When the button 1493 is pressed, the button 1493 squeezes the spring 1494, and the spring 1494 is deformed. The fixing plate 1491 is fixed with the rotating shaft as the The rotation center rotates, the button 1493 moves down, and the stopper 1492 moves up, making room for the mounting bracket 1431 to extend in or out. After releasing the button 1493, the spring 1494 loses its squeezing force, and the spring 1494 recovers its deformation and reversely squeezes the button 1493 to move up. When the button 1493 moves up, the stopper 1492 drops, and the stopper 1492 blocks the through slot, thereby preventing the mounting bracket 1431 from separating from the swing arm 142. At the same time, due to the limitation of the spring 1494, the stopper 1492 can also be effectively prevented from moving up, making the mounting bracket 1431 of the raking net 143 more stably connected to the swing arm 142.

[0041] Please refer to Figure 4, which is a three-dimensional view of the inner shell of the cat litter box of the present invention. The outer wall of the inner shell 112 is also provided with a fixing seat 1123 for installing the motor 144. The fixing seat 1123 is used to install the motor 144 so that the motor 144 can stably drive the rotating shaft.

[0042] Protective covers 1122 are also provided on both sides of the inner shell 112, and the second synchronous wheel 148 is located inside the protective covers 1122. On the one hand, the protective covers 1122 are used to prevent foreign objects from entering. On the other hand, the protective covers 1122 are used to protect the user and prevent the user's clothes or fingers from accidentally reaching into the second synchronous wheel 148.

[0043] A slope is also provided on one side of the stopper 1492, which is used to facilitate the installation frame 1431 to extend behind the stopper 1492. During installation, there is no need to press the button 1493.

[0044] Working principle:

[0045] When cleaning pet feces, first, the motor 144 rotates and drives the rotating rod 145 to rotate. When the rotating rod 145 rotates, it drives the first synchronous wheels 147 at both ends of the rotating rod 145 to rotate. Due to the action of the synchronous belt 146, when the first synchronous wheel 147 rotates, it drives the second synchronous wheel 148 to rotate through the synchronous belt 146. When the second synchronous wheel 148 rotates, it drives the swing arm 142 to rotate. Since the mounting bracket 1431 of the rake net 143 is connected to the swing arm 142, the swing arm 142 rotates and drives the rake net 143 to move. The rake net 143 uses the swing arm 142 as the rotation center to clean the pet feces in the litter box 12. Cleaning, during the rotation of the swing arm 142, when the swing arm 142 blocks the first sensor 1121 or the second sensor 1124, the drive component operates normally. When the pet enters the litter box 12 to defecate, due to the large size of the pet, when the pet blocks the first sensor 1121 and the second sensor 1124 at the same time, the motor 144 stops rotating, thereby facilitating the pet to defecate in the litter box 12. Furthermore, there are multiple sensors that can sense and monitor the litter box 12 in all directions, preventing blind spots after smaller pets enter the litter box 12, making it safer for pets to defecate.

[0046] When the raking net 143 is stuck with pet feces and needs to be cleaned, first, the button 1493 is pressed, and the button 1493 squeezes the spring 1494, and the spring 1494 is deformed. When the button 1493 moves down, the fixing plate 1491 rotates with the shaft as the rotation center. When the button 1493 moves down, the stopper 1492 rises. After the stopper 1492 rises, the mounting frame 1431 loses the limit of the stopper 1492, and the mounting frame can be moved. 1431 is pulled out from the through slot, thereby completing the disassembly of the mounting bracket 1431. After releasing the button 1493, the spring 1494 loses the squeezing force of the button 1493, and the spring 1494 recovers its deformation. When the spring 1494 recovers its deformation, it drives the button 1493 to move upward. When the button 1493 moves upward, the stopper 1492 drops, and the stopper 1492 is re-located in the through slot. Further, when the mounting bracket 1431 of the raking net 143 is to be installed, the mounting bracket 1431 is pulled out from the through slot, thereby completing the disassembly of the mounting bracket 1431. 431 extends into the through slot. When the mounting bracket 1431 fits with the stopper 1492, the stopper 1492 continues to be pushed. Due to the effect of the inclined surface of the stopper 1492, when the mounting bracket 1431 pushes the stopper 1492, the stopper 1492 moves upward, and the button 1493 squeezes the spring 1494. When the mounting bracket 1431 passes through the stopper 1492, the spring 1494 recovers its deformation and squeezes the button 1493. The button 1493 rises and the stopper 1492 falls. The stopper 1492 limits the mounting frame 1431 again, thereby preventing the mounting frame 1431 from being separated from the stopper 1492, so that the raking net 143 can be stably connected to the swing arm 142. The structure of installing and removing the raking net 143 connected to the swing arm 142 is simple. You only need to remove the raking net 143 from the swing arm 142 to clean the raking net 143 separately. Not only is cleaning convenient, but the raking net 143 can also be fully cleaned after being removed, and cleaning is cleaner.

[0047] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined by the claims.
