The screened contaminated cat litter particles are located on the surface of the flat plate and roll along the surface of the flat plate to the third opening as the shovel body rotates, and then enter the receiving cavity of the drawer through the fourth opening. This dynamic cleaning mechanism can timely screen out the contaminated cat litter particles and quickly transfer them to the drawer, avoiding the long-term contact of the contaminated cat litter particles with the indoor air, thereby effectively controlling the generation of odor gases. The static sealing function means that when the shovel body is stationary, one end of the arc-shaped member contacts the receiving cavity, and the other end contacts the hollow cavity. The hollow cavity, the arc-shaped member, and the receiving cavity are sequentially assembled to form an isolation structure that covers the third opening and isolates the chamber from the fourth opening. Through this isolation structure, the contaminated cat litter particles are isolated in a relatively closed space composed of the cat box, the feces box, and the drawer, effectively preventing the diffusion of odor gases generated by the contaminated cat litter particles and ensuring that the odor gases will not easily escape into the indoor environment, thereby reducing the impact on the indoor air quality. By combining dynamic cleaning with static sealing, this pet cat toilet can significantly improve the air quality of the indoor environment and effectively enhance the odor control effect.

[0046] Please refer to Figure 1-20 As shown, the present invention provides a pet cat litter box, which includes a control circuit, a cat box 10, a feces box 20, and a drawer 30; the cat box 10 is detachably connected to the feces box 20, the feces box 20 includes a housing 21 and a cat litter shoveling structure 22, and the cat litter shoveling structure 22 is electrically connected to the control circuit;

[0047] A first opening 11 is provided on the side wall of the cat box 10. The interior of the cat box 10 is a hollow cavity, which is communicated with the first opening 11, and a second opening 12 is provided at the bottom of the hollow cavity;

[0048] A receiving cavity 211 is formed by the downward depression of the upper surface of the housing 21. The receiving cavity 211 is communicated with the second opening 12. The receiving cavity 211 and the hollow cavity together form a chamber with a third opening. A fourth opening 212 is further provided on the upper surface of the housing 21, and a fifth opening 213 is provided at the lower part of the housing 21; when the drawer 30 slides into the housing 21 through the fifth opening 213 and closes the fifth opening 213, the receiving cavity of the drawer 30 is communicated with the fourth opening 212;

[0049] The cat litter shoveling structure 22 includes a shovel body 221, a first driving motor 222, and a first transmission gear 223; the shovel body 221 includes an arc-shaped member 2211, a flat plate 2212, and a connecting portion 2213. One end of the arc-shaped member 2211 is connected to one end of the flat plate 2212. The length of the line connecting the two ends of the arc-shaped member 2211 is less than the length of the flat plate 2212. One end of the connecting portion 2213 is connected to the arc-shaped member 2211 or the flat plate 2212, and the other end of the connecting portion 2213 is connected to the first transmission gear 223. A plurality of through holes for screening contaminated cat litter particles are provided on the flat plate 2212. The gear at the output shaft end of the first driving motor 222 meshes with the first transmission gear 223, and the shovel body 221 can rotate around the first driving motor 222;

[0050] When the shovel body 221 is stationary, the arc-shaped member 2211 covers the third opening and isolates the chamber from the fourth opening 212; when the shovel body 221 rotates along the accommodating cavity 211, the arc-shaped member 2211 separates from the third opening, and the chamber communicates with the fourth opening 212 through the third opening. The contaminated cat litter particles are conveyed by the flat plate 2212 to the third opening and enter the accommodating cavity through the fourth opening 212.

[0051] Specifically, the cat box 10 is detachably connected above the housing 21 to facilitate the installation, disassembly, and cleaning of the cat box 10 and the litter box 20. The first opening 11 is for the pet cat to enter and exit the cat box 10. The second opening 12 is for communicating with the accommodating cavity 211 of the litter box 20, and the accommodating cavity 211 is for placing cat litter particles. The cross-sectional shape of the chamber is quasi-circular, and the lower part of the quasi-circular shape is a smooth arc to match the arc-shaped member 2211 and facilitate the rotation of the arc-shaped member 2211 along the accommodating cavity 211. The fourth opening 212 is for communicating with the accommodating cavity of the drawer 30. The shape of the fourth opening 212 is funnel-shaped to facilitate the smooth fall of the contaminated cat litter particles. The fifth opening 213 is for the drawer 30 to slide in and out of the housing 21 and can be provided on the side wall of the housing 21. A handle position can also be provided on the front of the drawer 30 to facilitate the owner to grasp with fingers and smoothly pull out the drawer 30. The flat plate 2212 can also be called a perforated plate, and the perforated plate is used to screen the contaminated cat litter particles. Because cat hair, food residues, etc. are mixed into the clean cat litter particles, the overall volume of the particles will increase. After the clean cat litter particles come into contact with the liquid, their volume will also increase. Therefore, by setting the size of the through holes to be larger than the size of the clean cat litter particles and smaller than the size of the contaminated cat litter particles, the contaminated cat litter particles can be screened out. When the shovel body 221 rotates along the accommodating cavity 211, the contaminated cat litter particles on the surface of the flat plate 2212 roll along the surface of the flat plate 2212 to the third opening. The length of the line connecting the two ends of the arc-shaped member 2211 is less than the length of the flat plate 2212, which means that a part below the flat plate 2212 is not blocked by the arc-shaped member 2211, so that after the clean cat litter particles are shoveled up by the shovel body 221, they can quickly fall back into the accommodating cavity 211 through the through holes, improving the screening efficiency, facilitating the orderly scattering of the clean cat litter particles, and facilitating the subsequent use of the pet cat.

[0052] Compared with the prior art, the pet cat toilet proposed in this embodiment can achieve the dual functions of dynamic cleaning and static enclosure. The dynamic cleaning function means that when the first drive motor 222 is started, the shovel body 221 will be driven to rotate along the accommodation cavity 211 to shovel the cat litter, and the contaminated cat litter particles will be screened out through the through holes of the flat plate 2212. The screened contaminated cat litter particles are located on the surface of the flat plate 2212, and roll along the surface of the flat plate 2212 to the third opening as the shovel body 221 rotates, and then enter the accommodation cavity of the drawer 30 through the fourth opening 212. This dynamic cleaning mechanism can timely screen out the contaminated cat litter particles and quickly transfer them to the drawer 30, avoiding the long-term contact of the contaminated cat litter particles with the indoor air, thereby effectively controlling the generation of odor gases. The static enclosure function means that when the shovel body 221 is stationary, one end of the arc-shaped member 2211 contacts the accommodation cavity 211, and the other end contacts the hollow cavity. The hollow cavity, the arc-shaped member 2211 and the accommodation cavity 211 are sequentially joined to form an isolation structure that covers the third opening and isolates the chamber from the fourth opening 212. Through this isolation structure, the contaminated cat litter particles are isolated in a relatively enclosed space composed of the cat box 10, the toilet box 20 and the drawer 30, effectively preventing the diffusion of odor gases generated by the contaminated cat litter particles and ensuring that the odor gases do not easily escape into the indoor environment, thereby reducing the impact on the indoor air quality. By combining dynamic cleaning with static enclosure, this pet cat toilet can significantly improve the air quality of the indoor environment and effectively enhance the odor control effect.

[0053] In some embodiments of the present application, when the shovel body 221 is stationary, the flat plate 2212 forms an angle of 70-85 degrees with the horizontal direction; when the flat plate 2212 rotates to an angle of 15-30 degrees with the horizontal direction, the contaminated cat litter particles are conveyed to the third opening by the flat plate 2212.

[0054] Specifically, please refer to Figure 8As shown, the shovel body 221, also known as a crescent shovel, is shaped like a crescent moon. The shovel body 221 is located inside the hollow cavity of the cat box 10 and can rotate around the first drive motor 222. When the shovel body 221 is in a stationary state, it is located on the side of the cat box 10 and forms an angle of 70 - 85 degrees with the horizontal direction, just blocking the third opening, thereby isolating the fourth opening 212 communicating with the accommodation cavity of the drawer 30, so as to ensure that the odor gas generated by the contaminated cat litter particles stored in the drawer 30 will not volatilize into the cat box 10 and the outside. When the shovel body 221 is in the state of shoveling cat litter (once this pet cat toilet detects that the pet cat enters and leaves the cat box 10 within a certain period of time, it means that the pet cat has defecated in the clean cat litter particles in the cat box 10, and the shoveling function can be activated after the pet cat leaves), the shovel body 221 will rotate multiple times and finally turn to a position forming an angle of 15 - 30 degrees with the horizontal direction, so that the selected contaminated cat litter particles can just fall out of the third opening and fall into the fourth opening 212, and then enter the accommodation cavity of the drawer 30.

[0055] In some embodiments of the present application, the accommodation cavity 211 includes a first arc portion 2111, a second arc portion 2112, and an arc-shaped insertion plate 2113. A slot for inserting the insertion plate 2113 is further provided at the lower part of the housing 21, and the first arc portion 2111 and the second arc portion 2112 are respectively located on both sides of the slot; when the insertion plate 2113 is inserted into the slot, the first arc portion 2111, the insertion plate 2113, and the second arc portion 2112 are sequentially connected to form a complete arc structure.

[0056] Specifically, please refer to Figure 9 and Figure 10 As shown, the slot is designed to be an arc shape matching the shape of the insertion plate 2113 to ensure that the insertion plate 2113 can be smoothly inserted and fixed in place. After the insertion plate 2113 is inserted into the slot, the accommodation cavity 211 forms a complete arc structure, which not only facilitates the rotation of the shovel body 221 but also helps prevent the leakage of clean cat litter particles.

[0057] In some embodiments of the present application, the drawer 30 includes a second drive motor 31, a cylindrical turntable 32, a first receiving box 33, and a plurality of second receiving boxes 34; wherein, the first receiving box 33 and all the second receiving boxes 34 are located within the turntable 32, and the first receiving box 33 is correspondingly arranged below the plug board 2113; when the plug board 2113 is not inserted into the slot, the first receiving box 33 communicates with the accommodation cavity 211; all the second receiving boxes 34 are sequentially joined together to form a hollow structure, the first receiving box 33 is arranged in the hollow area of the hollow structure and together with the second receiving boxes 34 forms a cylindrical structure, the second drive motor 31 is located at the center position of the turntable 32 and is electrically connected to the control circuit, and the turntable 32 can rotate around the second drive motor 31 under the drive of the second drive motor 31; when the turntable 32 rotates, the first receiving box 33 and all the second receiving boxes 34 rotate synchronously; when the turntable 32 is stationary, one of the second receiving boxes 34 is located below the fourth opening 212.

[0058] Specifically, please refer to Figure 11 and Figure 12 As shown, the first receiving box 33 and the second receiving boxes 34 are both located within the turntable 32 and can be conveniently taken out and put into the turntable 32. The contaminated cat litter particles fall into one of the second receiving boxes 34 below through the fourth opening 212, and a gravity sensor 351 is further arranged below the second receiving box 34. When the gravity sensor 351 detects that the second receiving box 34 above is full, it will automatically rotate the turntable 32 so as to turn the next empty second receiving box 34 to below the fourth opening 212 until all the second receiving boxes 34 are full. At this time, the control circuit will notify the owner to pull out the drawer 30 to clean the contaminated cat litter particles. During the cleaning process, the owner does not need to clean the second receiving boxes 34 separately, and can pour the contaminated cat litter particles in the surrounding second receiving boxes 34 into the middle first receiving box 33 and only clean the first receiving box 33 once. When new cat litter needs to be replaced, the owner only needs to pull out the plug board 2113 of the housing 21, and the old cat litter can easily fall into the first receiving box 33, and the whole replacement process is time-saving and labor-saving.

[0059] In some embodiments of the present application, the drawer 30 further includes a chassis 35, a position encoder 36, and a second transmission gear 37; wherein, the position encoder 36, the second transmission gear 37, and the turntable 32 are all located within the chassis 35, and the position encoder 36 is connected to the central position of the second transmission gear 37. The outer wall of the turntable 32 is provided with gear teeth, and the gear teeth mesh with the second transmission gear 37; when the turntable 32 rotates, the turntable 32 drives the position encoder 36 to rotate through the meshing movement of the gear teeth and the second transmission gear 37.

[0060] Specifically, please refer to Figure 13 and Figure 14 As shown, the position encoder 36 is a sensor used to measure the position state of an object. It converts the movement of the object into an electrical signal to provide precise position feedback. When the turntable 32 rotates, the position encoder 36 also rotates accordingly to record the position change of the turntable 32 in real time. This means that when replacing the second storage box 34, the position encoder 36 will automatically update its feedback information to accurately reflect the current position of the second storage box 34.

[0061] In some embodiments of the present application, a gravity sensor 351 is provided at the inner bottom of the chassis 35 corresponding to the position of the fourth opening 212, and the gravity sensor 351 is electrically connected to the control circuit.

[0062] Specifically, when there are no contaminated cat litter particles or the weight of the contaminated cat litter particles in the second storage box 34 located below the fourth opening 212 is light, no pressure is exerted on the gravity sensor 351. When the second storage box 34 collects a certain amount of contaminated cat litter particles (usually close to being full), its bottom plate will press down on the gravity sensor 351. The gravity sensor 351 feeds back the detected pressing signal to the control circuit. Once the control circuit receives this pressing signal, it will start the second drive motor 31 to drive the turntable 32 to rotate and move the empty second storage box 34 below the fourth opening 212 to continue accommodating the contaminated cat litter particles. It should be noted that during the process of replacing the second storage box 34, the sand scooping work of the scooping body 221 needs to be paused to avoid the overflow or chaos of the contaminated cat litter particles, thereby ensuring the cleanliness of the overall environment.

[0063] In some embodiments of the present application, two parallel and separated ridges 352 are provided on the outer bottom of the chassis 35, and two through grooves 214 are provided on the housing 21 corresponding to the ridges 352; when the drawer 30 slides into the housing 21, the ridges 352 slide into the corresponding through grooves 214.

[0064] Specifically, the presence of the raised strips 352 and the through grooves 214 enables the drawer 30 to quickly and accurately find a clear guiding path during the process of sliding into the housing 21, avoiding jamming or deviation caused by incorrect positioning, ensuring that the drawer 30 can slide into the housing 21 easily and smoothly, and improving the user experience.

[0065] In some embodiments of the present application, an access control structure is provided on one side of the first opening 11 of the cat box 10. The access control structure includes a door panel 131, a rack 132, a channel 133, and a third drive motor 134. The door panel 131 is fixedly connected to the rack 132. The rack 132 is disposed in the channel 133 and can move back and forth along the channel 133. The gear at the output shaft end of the third drive motor 134 meshes with the rack 132, and the third drive motor 134 is electrically connected to the control circuit. When the third drive motor 134 drives the rack 132 to move back and forth along the channel 133 through the meshing movement of the gear at the output shaft end and the rack 132, the door panel 131 moves back and forth synchronously to close or open the first opening 11.

[0066] Specifically, please refer to Figure 15-Figure 20 As shown, a cat face-shaped outer shell can be added in front of the cat box 10 to increase the interest and attractiveness of the product. The control part of the access control structure is arranged behind the outer shell, and only the door panel 131 is left outside. This can not only hide the access control structure and keep the overall structure of the cat box 10 tidy, but also does not affect the realization of the closing and opening functions of the first opening 11. A cat head-shaped outer shell can also be added behind the cat box 10, and the control circuit can be hidden behind it, which helps to improve the overall aesthetics of the cat box 10.

[0067] In some embodiments of the present application, a sixth opening is provided at the top of the cat box 10. The sixth opening communicates with the hollow cavity. The cat box 10 further includes a cover plate 14 that is hinged to one side of the sixth opening and can be opened and closed.

[0068] Specifically, the sixth opening is the entrance for adding new cat litter. When new cat litter needs to be placed, the cover plate 14 on the sixth opening can be opened for operation. During the normal use of the pet cat toilet, the cover plate 14 should be kept closed to avoid interfering with the internal environment of the hollow cavity.

[0069] In some embodiments of the present application, two buckles 15 are symmetrically arranged on the side wall of the cat box 10, and two buckle positions 215 corresponding to the buckles 15 are arranged on the side wall of the housing 21. When the buckles 15 are snapped into the corresponding buckle positions 215, the cat box 10 is connected to the toilet box 20. When the buckles 15 are disengaged from the corresponding buckle positions 215, the cat box 10 is separated from the toilet box 20.

[0070] Specifically, through the cooperation of the buckle 15 and the buckle position 215, the cat box 10 and the feces box 20 can be easily connected or separated, facilitating cleaning. It should be noted that the cooperation between the buckle 15 and the buckle position 215 is just one way of detachable connection. According to specific structural designs, other connection methods can also be selected, which will not be elaborated with examples here.

[0071] In some embodiments of the present application, an infrared sensor is provided on one side of the first opening 11 of the cat box 10, and the infrared sensor is electrically connected to the control circuit.

[0072] Specifically, the infrared sensor can be provided at the ear position of the cat face-shaped outer shell. The infrared sensor can detect the behavior of the pet cat entering and leaving the cat box 10, thereby controlling the opening and closing of the access control structure, as well as starting and stopping the rotation of the shoveling body 221. For example: once the infrared sensor detects that the pet cat enters the cat box 10, it immediately activates the safety mechanism to stop all moving parts from operating immediately, ensuring the absolute safety of the pet cat during the toilet process. Once the infrared sensor detects that the pet cat leaves the cat box 10, it immediately controls the access control structure to close the first opening 11 and starts the shoveling body 221 to perform sand shoveling and cleaning. At the same time, an ultraviolet disinfection lamp can also be provided at the ear position to effectively kill bacteria in the cat box 10, ensuring the hygiene and safety of the cat box 10. Moreover, an incense device can also be provided at the ear position to release a fresh smell. The addition of the incense device keeps the air in the cat box 10 fresh at all times, being able to create a more comfortable environment for the pet cat. In addition, a camera can also be provided on the cat box 10 to facilitate recording basic information of the pet cat, such as activity status, eating habits, and excretion conditions, etc., and also enable the owner to view the dynamics of the pet cat at any time through the application program, enhancing the friendly interaction between the owner and the pet cat.

[0073] The following gives an example to illustrate the usage process of this pet cat toilet, which specifically includes:

[0074] In the initial state of the pet cat toilet, the door panel 131 remains open, and the shovel body 221 is located on the side of the cat box 10 and forms an angle of 70 - 85 degrees with the horizontal direction, just blocking the third opening and isolating the fourth opening 212. At this time, the pet cat can enter and exit the cat box 10 normally. When the pet cat enters the cat box 10, the infrared sensor detects the entry signal, and the control circuit makes all the motion systems remain silent. When the pet cat finishes defecating and leaves, the infrared sensor detects the leaving signal, and the control circuit closes the door panel 131 and controls the shovel body 221 to rotate clockwise multiple times from the initial position until it finally rotates to a position forming an angle of 15 - 30 degrees with the horizontal direction. At this time, the contaminated cat litter particles above the flat plate 2212 will roll through the third opening to the fourth opening 212 and fall into the second receiving box 34. After the contaminated cat litter particles are collected, the control circuit opens the door panel 131 again to wait for the next use of the pet cat. When the second receiving box 34 collects a certain amount of contaminated cat litter particles, its bottom plate will press down the gravity sensor 351, and the gravity sensor 351 feeds back the pressing signal to the control circuit. The control circuit then controls the second drive motor 31 to drive the turntable 32 to rotate and move the empty second receiving box 34 to the lower part of the fourth opening 212. When all the second receiving boxes 34 are filled, the control circuit will close the door panel 131 and emit a prompt sound to remind the owner to clean the contaminated cat litter particles.

[0075] The pet cat toilet provided in this embodiment can effectively clean the feces and hair in the cat litter in the placement cavity, realize the automatic cleaning of the pet cat's urine and feces, thereby extending the replacement cycle of the cat litter from several days to dozens of days and reducing the handling frequency of the owner. At the same time, its structural design is compact and ingenious, which can effectively isolate odors and has a wide application prospect for promotion.
