[0040] At present, automatic cat litter boxes with drums generally include a base and a rotating drum. The cat feces and cat litter are separated by the rotation of the drum, so that the cat litter in the cat litter box is kept clean, and the cat feces are discharged into the feces collection box. In some products, the feces collection box is set in the base or the drum. There is a common problem that the cat's turning space inside the drum is small and the feces collection box is small in size.

[0041] In view of this, in order to solve the problem that the feces collecting box of the existing drum cat litter box is set in the base or the drum, and the drum or the feces collecting box has a small space, the present invention proposes a cat litter box 100, aiming to improve the above problem.

[0042] The specific structure of the cat litter box 100 of the present invention will be described below:

[0043] Please refer to Figures 1 to 13 The present invention provides a cat litter box 100, which includes: a base 10, the base 10 is provided with a mounting cavity 11 and a first opening 14 connected to the mounting cavity 11; a feces collecting box 20, the feces collecting box 20 is arranged on the outside of the base 10; and a drum 30, the drum 30 is rotatably arranged in the mounting cavity 11, the drum 30 is provided with a accommodating cavity 311 and a cat litter temporary storage bin 32 and a feces ball temporary storage bin 33 connected to the accommodating cavity 311, the accommodating cavity 311 has a second opening 3111, and the drum 30 also An outlet 34 connected to the feces temporary storage bin 33 is provided; wherein the cat litter box 100 has a drum 30 that rotates relative to the base 10, so that the second opening 3111 corresponds to the first opening 14 in a defecation state and the second opening 3111 is staggered from the first opening 14 in a screening state; in the defecation state, the outlet 34 is connected to the feces collection box 20; in the screening state, the outlet 34 is closed, and the cat litter and feces located in the accommodating cavity 311 are discharged into the cat litter temporary storage bin 32 and the feces temporary storage bin 33 in turn.

[0044] Specifically, the cat litter box 100 includes a base 10, a feces collecting box 20 and a drum 30. The base 10 is used to install the drum 30 and provide a rotating space for the drum 30. The drum 30 is used to place cat litter for cats to go to the toilet. The feces collecting box 20 is used to collect cat feces.

[0045] The drum 30 is rotatably connected to the mounting cavity 11 of the base 10, and the specific way of the rotational connection of the drum 30 can be driven by a motor connection or a gear rack connection. In this embodiment, the drum 30 is controlled to rotate by a motor, and the motor is controlled by a main control system.

[0046] The second opening 3111 of the drum 30 is used for the cat to enter, and the first opening 14 of the base 10 is used to place the drum 30. Fig. 9 and 13 , the first opening 14 of the base 10 and the second opening 3111 of the drum 30 are located on the same plane 38 .

[0047] A accommodating chamber 311, a cat litter temporary storage bin 32 and a feces ball temporary storage bin 33 are provided in the drum 30. The accommodating chamber 311 is used to place cat litter for cats to use when going to the toilet. The drum 30 rotates so that the cat litter and feces in the accommodating chamber 311 enter the cat litter temporary storage bin 32 and the feces ball temporary storage bin 33 in turn, and finally the feces ball 200 flows into the feces collecting box 20 from the outlet 34 in the feces ball temporary storage bin 33.

[0048] like Fig.11 , which is the screening state of the cat litter box 100, the outlet 34 of the feces ball temporary storage bin 33 is closed, the drum 30 gradually rotates clockwise, the second opening 3111 of the drum 30 is staggered with the first opening 14 of the base 10, the cat litter first enters the cat litter temporary storage bin 32, the drum 30 continues to rotate, and the feces ball 200 outside the cat litter temporary storage bin 32 falls into the feces ball temporary storage bin 33 under the action of gravity.

[0049] like Fig.12 , which is the defecation state of the cat litter box 100, the drum 30 rotates counterclockwise to return to its original position, the second opening 3111 of the drum 30 corresponds to the first opening 14 of the base 10, that is, they are located on the same plane 38, at this time, the outlet 34 of the feces ball temporary storage bin 33 is opened and connected to the feces collecting box 20, and the feces ball 200 located in the feces ball temporary storage bin 33 flows out from the outlet 34 into the feces collecting box 20 under the action of gravity, completing the collection of the feces ball 200.

[0050] In the screening state, cat litter and feces enter different temporary storage bins respectively; in the defecation state, the feces ball 200 directly enters the external feces collection box 20 through the outlet 34; this design improves the separation efficiency and ensures the cleanliness of the cat litter. The specially designed feces ball temporary storage bin 33 and cat litter temporary storage bin 32 help to more effectively separate cat litter and feces, avoid mixing the two, and thus maintain the cleanliness of the cat litter.

[0051] The outlet 34 of the temporary storage bin 33 for feces can be opened and closed by an electrically or manually driven sliding door 42, or by a pneumatic or hydraulic mechanism that can be used to push a piston to control the opening and closing of the door. The opening and closing of the outlet 34 of the temporary storage bin 33 for feces can also be controlled by an electromagnet 43 as described below that generates a magnetic field through electric current to attract or release the sliding door 42.

[0052] This collection method enables the feces collection box 20 to be placed outside the base 10. By placing the feces collection box 20 of the cat litter box 100 at the rear, the rear feces collection box 20 can be raised and enlarged without being restricted by the body 221, so that the volume of the feces collection box 20 can be increased. Figure 2Because the feces collecting box 20 is placed outside the base 10 and is no longer limited by the internal space, the design can be more flexible and its size can be adjusted according to needs. This not only increases the space for storing cat feces, reduces the frequency of cleaning by the owner, but also makes it more convenient to dump and clean.

[0053] After removing the feces collecting box 20, the space originally used to place the feces collecting box 20 is released, and the cat can turn around and rest. This is especially beneficial for larger cats, reducing the sense of oppression when the cat uses the feces collecting box and improving the comfort.

[0054] Since the feces collecting box 20 is moved to the outside, feces can fall directly into the closed container, reducing the chance of odor emitting to the inside of the cat litter box 100 and other areas. The owner can more easily observe the fullness of the feces collecting box 20 and clean it in time to avoid hygiene problems caused by neglect.

[0055] The technical solution of the present invention is that the drum 30 is rotatably arranged in the installation cavity 11, and the base 10 provides a rotation space for the drum 30. The drum 30 rotates relative to the base 10, so that the cat litter box 100 has a screening state and a defecation state. In the screening state, the drum 30 rotates to gradually separate the cat litter and feces in the accommodating cavity 311; in the defecation state, the drum 30 rotates in the opposite direction, so that the outlet 34 is connected to the feces collecting box 20, and the feces ball 200 falls out of the outlet 34, thereby discharging the feces ball 200 into the feces collecting box 20; the feces collecting box 20 is arranged on the outside of the base 10 to collect the screened feces ball 200; by arranging the feces collecting box 20 on the outside of the base 10, the external feces collecting box 20 can be enlarged in size without being restricted by the drum 30 or the base 10, such as being heightened or widened, so that the volume of the feces collecting box 20 can be enlarged; because the feces collecting box 20 does not occupy space inside or at the bottom of the drum 30, the accommodating cavity 311 in the drum 30 can provide more activity space for the cat.

[0056] In an embodiment of the present invention, the drum 30 includes: an outer shell 31, the outer shell 31 is provided with a accommodating chamber 311, a second opening 3111 and an outlet 34; a screening element 35, the screening element 35 is connected to the outer shell 31, the screening element 35 divides the drum 30 into the accommodating chamber 311, the cat litter temporary storage bin 32 and the feces ball temporary storage bin 33, the screening element 35 is provided with a screening hole 3531 connecting the accommodating chamber 311 and the cat litter temporary storage bin 32 and an entrance 36 connecting the accommodating chamber 311 and the feces ball temporary storage bin 33.

[0057] In detail, the inside of the drum 30 is divided into different functional areas by the screening element 35, which can maintain the functional independence of each area; the design of the screening hole 3531 and the inlet 36 can achieve more efficient separation of cat litter and feces, and smaller cat litter particles can be returned to the cat litter temporary storage bin 32 through the screening hole 3531, while larger feces are directed to the feces temporary storage bin 33, which can maximize the use of limited space. By separating and removing feces in time, the risk of contamination can be reduced and good sanitary conditions can be maintained. At the same time, effective separation can keep the environment in the cat litter box 100 cleaner and reduce the chance of odor and bacterial growth.

[0058] The user does not need to manually separate the cat litter and feces, which is more automated and easier to operate. The screening element 35 can be a grid-shaped screen plate or a multi-layer screen, etc., which can be adjusted or designed according to different cat litter characteristics to ensure the best separation effect. According to the size of the screening hole 3531, the type of cat litter suitable for the cat litter box 100 can be selected, such as a clumping type or a granular cat litter.

[0059] In an embodiment of the present invention, the screening element 35 includes a first screening element 351, a second screening element 352 and a third screening element 353. The first screening element 351 is connected to one end of the second opening 3111, the second screening element 352 is connected to the inner wall of the outer shell 31 and extends toward the first screening element 351, and the third screening element 353 is connected to the inner wall of the outer shell 31 and extends toward the second screening element 352; the third screening element 353, the second screening element 352 and the inner wall of the outer shell 31 are enclosed to form a cat litter temporary storage bin 32, and the third screening element 353 is provided with screening holes 3531; the first screening element 351, the second screening element 352 and the inner wall of the outer shell 31 are enclosed to form a feces temporary storage bin 33, the second screening element 352 and the first screening element 351 are spaced apart and form an inlet 36, and the outlet 34 is provided on the wall surface of the outer shell 31.

[0060] It is worth noting that Fig. 9 By connecting the first screening element 351 to one end of the second opening 3111, and the second screening element 352 extending toward the first screening element 351, a clear separation path is formed. When the drum 30 rotates, the cat litter and feces will first contact the third screening element 353, and then be guided to the screening hole 3531 for screening to filter the cat litter, so that only cat litter particles that meet the size requirements can pass through and enter the cat litter temporary storage bin 32, while larger feces will remain on it and enter the feces ball temporary storage bin 33.

[0061] The first sieving member 351 is integrally formed with the housing 31. The first sieving member 351 and the second sieving member 352 are detachable from the housing 31, and a spacing is provided between the two to form an inlet 36, so that feces can enter the feces ball temporary storage bin 33 from the inlet 36. Fig.11The feces 200 will be discharged toward the inlet 36 along the surface of the third screening element 353, and the first screening element 351 can catch the feces 200, allowing the feces 200 to enter the feces temporary storage bin 33, providing enough space for the feces 200 to be separated.

[0062] The cat litter temporary storage bin 32 formed by the third screening element 353 and the second screening element 352 effectively utilizes the internal space, increases the available volume, and maintains a compact structure. By cleverly arranging the position and shape of the screening element 35, the capacity of the functional area can be maximized within a limited space, without wasting space or affecting the work of other components.

[0063] like Fig. 9 The inner wall of the feces ball temporary storage bin 33 is arranged in an arc surface 37, and the cross-sectional area of ​​the feces ball temporary storage bin 33 gradually decreases from the entrance 36 toward the outlet 34, so as to guide the feces ball 200, so that the feces ball 200 gradually moves from the entrance 36 toward the outlet 34 under the action of gravity, and is finally discharged from the outlet 34.

[0064] Furthermore, in one embodiment, if Figure 1 and Fig.10 The width of the third sifting element 353 is consistent with the width of the accommodating chamber 311, while the width of the second sifting element 352 is smaller than the width of the accommodating chamber 311. Since the outer walls of the third sifting element 353 and the second sifting element 352 and the inner wall of the shell 31 are enclosed to form the cat litter temporary storage bin 32, both sides of the second sifting element 352 can also be used as part of the cat litter temporary storage bin 32 to store cat litter, so as to store a larger volume of fine litter. In one embodiment, 9 liters of fine litter can be separated and temporarily stored.

[0065] And, if Figure 9-11 A clamping block 3521 is protruded from the second screening element 352 near the third screening element 353, and a clamping groove 3532 is correspondingly provided on the third screening element 353. The clamping block 3521 is inserted into the clamping groove 3532 to connect the second screening element 352 with the third screening element 353, that is, the third screening element 353 is arranged to surround the second screening element 352, and an avoidance port connected to the inlet 36 is provided, so that the screened feces ball 200 enters the feces ball temporary storage bin 33 from the inlet 36.

[0066] In an embodiment of the present invention, a sliding door assembly 40 is provided at the outlet 34 , and the sliding door assembly 40 is slidably connected to the outlet 34 ; in the defecation state, the sliding door assembly 40 is used to open the outlet 34 ; in the screening state, the sliding door assembly 40 is used to close the outlet 34 .

[0067] Specifically, by providing the sliding door assembly 40, the outlet 34 can be accurately opened or closed according to the state (defecation or screening) of the drum 30. The specific structure of the sliding door assembly 40 can use a linear guide rail and a slider to guide the movement of the door plate, or a belt-driven sliding door or a hydraulic cylinder-driven sliding door, or can use the cooperation of the electromagnet 43 and the sliding door 42 as described below.

[0068] The sliding door assembly 40 ensures that the outlet 34 is opened only when feces need to be discharged, and remains closed at other times, thereby avoiding unnecessary material loss or mixing. When the sliding door 42 is opened, feces can fall directly into the feces collection box 20, and in the screening state, the sliding door 42 is closed so that cat litter and feces can be further separated in their respective temporary storage bins. The design of the sliding door assembly 40 can also prevent cat claws from accidentally getting stuck in the outlet 34.

[0069] In certain embodiments of the present invention, the sliding door assembly 40 includes a sliding rail 41, a sliding door 42 and an electromagnet 43. The peripheral side wall surface of the outlet 34 is recessed inward to form a mounting groove 39. The sliding rail 41 is fixedly connected to the mounting groove 39. The sliding door 42 is slidably connected to the sliding rail 41. The electromagnet 43 is connected to the base 10. The electromagnet 43 is used to adsorb the sliding door 42 to open or close the sliding door 42.

[0070] In other embodiments of the present invention, the sliding door assembly 40 includes a sliding rail 41, a sliding door 42 and an electromagnet 43. The sliding rail 41 is fixedly connected to the peripheral wall of the outlet 34, the sliding door 42 is slidably connected to the sliding rail 41, and the electromagnet 43 is connected to the base 10. The electromagnet 43 is used to adsorb the sliding door 42 to open or close the sliding door 42.

[0071] In detail, the sliding door assembly 40 is configured as a matching structure of a sliding rail 41, a sliding door 42 and an electromagnet 43. The sliding rail 41 includes two sections of tracks. The first section is a track close to the exit 34, and the second section is a track away from the exit 34. When the sliding door 42 is located in the first section, the exit 34 can be closed. When the sliding door 42 is located in the second section, the exit 34 can be opened.

[0072] like Figure 2 and Figure 4 The slide rail 41 can be embedded in the outer surface of the drum 30 in an embedded manner to keep the outer surface of the drum 30 flat and make the drum 30 turn over better. Figure 6-8 The slide rail 41 can also be directly fixed on the outer surface of the drum 30, which is convenient for connection.

[0073] like Fig. 9 and Fig.11The sliding door 42 is slidably connected to the slide rail 41. In the screening state, the drum 30 rotates clockwise. At this time, the electromagnet 43 is not energized, and the sliding door 42 closes the outlet 34; when changing from the screening state to the defecation state, the drum 30 rotates counterclockwise. During this process, the electromagnet 43 is energized to attract the sliding door 42, and the drum 30 continues to rotate counterclockwise (in this case, it is set to rotate 25.5°) to reach the defecation position. The sliding door 42 is acted upon by the suction force of the electromagnet 43 and slides relative to the drum 30 to gradually open the outlet 34, so that the feces ball 200 falls into the rear feces collecting box 20 through the outlet 34.

[0074] The electromagnet 43 can provide reliable switch control to ensure that the sliding door 42 is accurately opened or closed when needed, reducing the risk of mechanical wear and extending the service life of the equipment; the electromagnet 43 can complete the adsorption or release action in a very short time, thereby quickly opening or closing the sliding door 42. Compared with traditional gears, belts or other complex transmission mechanisms, the overall structure is simpler and more compact, and the process of the electromagnet 43 driving the sliding door 42 is relatively quiet and does not produce obvious mechanical noise.

[0075] In addition, silica gel or a spring is provided between the electromagnet 43 and the base 10, so that when the sliding door 42 is adsorbed, the sliding door 42 can be better fitted and adsorbed, thereby improving the reliability of use.

[0076] In addition, a spring or other structure may be used to automatically reset the sliding door 42 for the next use.

[0077] In some embodiments, two slide rails 41 are provided and are disposed on both sides of the outlet 34 . A slide groove 411 is provided on the slide rail 41 , and plug blocks 421 are provided on both sides of the sliding door 42 . The plug blocks 421 are inserted into the slide groove 411 so that the sliding door 42 is slidably connected to the slide rail 41 .

[0078] Specifically, the double slide rail 41 design provides better stability, ensuring that the sliding door 42 moves smoothly along the predetermined path during opening and closing. The cooperation between the slide groove 411 and the plug block 421 enables the sliding door 42 to be accurately positioned, ensuring the consistency and reliability of each opening and closing action. This tightly matched design reduces the shaking amplitude of the sliding door 42 during movement and improves the accuracy of operation. The design of the slide groove 411 and the plug block 421 facilitates the installation and subsequent adjustment of the sliding door 42, and effectively prevents the sliding door 42 from falling off during use.

[0079] In other embodiments, a through hole 413 is opened on the side of the slide rail 41, and the sliding door assembly 40 also includes a supporting member 44, which includes a spring 45 and a supporting block 46. The spring 45 is arranged in the through hole 413, one end of the spring 45 is connected to the slide rail 41, and the supporting block 46 is connected to the other end of the spring 45, and at least partially extends from the through hole 413 toward the direction close to the sliding door 42. A supporting groove 423 is recessed on the side of the sliding door 42 close to the slide rail 41, and the supporting block 46 is used to extend into the supporting groove 423 to lock the sliding door 42.

[0080] In detail, Figure 5 When the abutment block 46 extends into the abutment groove 423 on the sliding door 42, the sliding door 42 can be effectively locked to prevent the sliding door 42 from accidentally opening due to external vibration or slight collision. When the sliding door 42 needs to be opened, the electromagnet 43 absorbs the sliding door 42, which can easily overcome the resistance of the spring 45 and push the abutment block 46 out of the abutment groove 423; similarly, when the sliding door 42 needs to be closed, the spring 45 will automatically push the abutment block 46 into the abutment groove 423 to achieve automatic locking.

[0081] In addition, the abutting member 44 also includes a connecting block 47. A notch (not shown) communicating with the through hole 413 is provided on the side of the slide rail 41 away from the sliding door 42. The connecting block 47 is fixedly connected in the notch. One end of the spring 45 is fixedly connected to the connecting block 47. Through the connecting block 47, the force of the spring 45 can be more evenly distributed on the abutting block 46, ensuring the smoothness and consistency of its action, and ensuring that the spring 45 and the abutting block 46 can remain stable during long-term use. The design of the connecting block 47 allows the spring 45 to be pre-fixed in a clear position, which is convenient for rapid assembly and disassembly. At the same time, the presence of the notch also provides precise positioning for the connecting block 47, reducing installation errors.

[0082] The electromagnet 43 can absorb the sliding door 42 by setting the material of the sliding door 42 to a metal material that can be absorbed, or by Figure 5 As shown, a metal block 48 (such as an iron block or a steel block) that can be adsorbed by an electromagnet 43 is connected to the sliding door 42 , and the electromagnet 43 can adsorb the metal block 48 , thereby adsorbing the sliding door 42 .

[0083] In some other embodiments, an elastic clip 412 is protruding outward from the side of the slide rail 41, and the elastic clip 412 forms an elastic slot 4121. A clamping shaft 422 is protruding from the side of the sliding door 42, and the insert block 421 of the sliding door 42 is inserted into the slide slot 411, and the clamping shaft 422 is clamped in the elastic slot 4121.

[0084] In detail, when the sliding door 42 does not need to move, the engagement between the clamping shaft 422 and the elastic clamping groove 4121 provides a reliable limiting effect, preventing the sliding door 42 from accidentally moving due to vibration or slight collision, and ensuring that the sliding door 42 remains stable in a non-working state. When the electromagnet 43 adsorbs the sliding door 42, the sliding door 42 can overcome the limiting resistance between the clamping shaft 422 and the elastic clamping groove 4121, so that the sliding door 42 moves smoothly.

[0085] In a specific embodiment, if Figure 4 The sliding door 42 is located in the first section of the slide rail 41, and its card shaft 422 is locked on the elastic card buckle 412 of the slide rail 41. The sliding door 42 closes the outlet 34 of the drum 30, and the sliding door 42 and the drum 30 remain relatively stationary; it moves synchronously with the drum 30; when the outlet 34 needs to be opened, the drum 30 rotates, and the sliding door 42 is sucked by the electromagnet 43 to generate reverse friction. The locking force of the card shaft 422 on both sides of the sliding door 42 is less than the friction force, and the sliding door 42 slides clockwise relative to the drum 30 to the second section of the track, gradually opening the outlet 34 of the feces collecting box 20, and the feces 200 falls into the rear feces collecting box 20.

[0086] In this embodiment, a slide rail 41 and a sliding door 42 are designed, and an electromagnet 43 is used for adsorption control. A position feedback circuit such as a Hall sensor and software control are provided to enable the drum 30 to roll to a corresponding position, and the sliding door 42 to close or open the outlet 34, thereby achieving the separation, temporary storage, and defecation of cat litter and feces.

[0087] In the embodiment of the present invention, the cat litter box 100 has a use state in which the drum 30 is stationary relative to the base 10 so that the second opening 3111 corresponds to the first opening 14; in the use state, the outlet 34 is closed.

[0088] Specifically, after defecation, Fig. 9 , the outlet 34 is closed, and the cat litter in the temporary storage bin 32 falls into the accommodating chamber 311 under the action of gravity, so as to be convenient for the next use. In the use state, the drum 30 is in a stationary state, and the cat enters the cat litter box 100 for use, thereby avoiding rolling and causing harm to the cat, eliminating the risk of injury to the cat's claws or other parts of the body due to accidental rotation, and providing a safer use environment.

[0089] In an embodiment of the present invention, the base 10 includes a bottom wall 15 and two side walls 16 connected to the bottom wall 15, one side of the two side walls 16 forms a first opening 14, the drum 30 is connected between the two side walls 16, and the first opening 14 and the second opening 3111 are located in the same plane 38; the feces collecting box 20 is connected to the side of the base 10 facing away from the first opening 14.

[0090] In detail, the first opening 14 is located on one side of the two side walls 16, and the cat can enter the drum 30 from the second opening 3111 on one side, while the feces collecting box 20 is located on the other side. The feces collecting box 20 is placed on the back of the base 10, away from the cat's entry and exit path, providing a clear functional partition and reducing the risk of the cat touching or overturning the feces collecting box 20; the feces collecting box 20 is located on the back of the base 10, which helps to isolate the odor source and reduce the spread of odor to the use area. The closed design of the feces collecting box 20 can more effectively control the odor and keep the surrounding environment fresh.

[0091] like Figure 1 , Figure 2 and Fig.13 The bottom wall 15 also includes a front wall (not shown) and a rear wall (not shown). The front wall and the two side walls 16 enclose a first opening 14. The front wall is relatively low, which is convenient for cats to enter. The feces collection box 20 is connected to the rear wall. The open entrance 36 is designed to facilitate cats to enter and exit, and users can also more easily observe and approach the interior of the cat litter box 100; the independent setting of the feces collection box 20 makes it easier to disassemble and clean without affecting the normal use of other parts. Users can easily remove the feces collection box 20 for cleaning or replacement without moving the entire device, which simplifies the maintenance process.

[0092] In some embodiments, the feces collecting box 20 includes a box body 21 and a cover body 22, the box body 21 is detachably connected to the outer side of the base 10, and the cover body 22 is detachably connected to the box body 21, the box body 21 and the cover body 22 enclose a collection port 201 and are used to communicate with the outlet 34, and the feces collecting box 20 has an installed state and a stored state; in the installed state, the box body 21 is connected to the base 10; in the stored state, the box body 21 and the cover body 22 are stored in the accommodating cavity 311 of the drum 30.

[0093] Specifically, Figure 4 When the box body 21 is installed on the base 10, the feces 200 can be collected; when the box body 21 is removed from the base 10, the cover body 22 can also be removed from the box body 21, and the box body 21 and the cover body 22 can be stored in the accommodating cavity 311 of the drum 30, which significantly reduces the volume of the product, facilitates packaging, transportation and storage, reduces the required packaging space and packaging materials, reduces logistics costs, and is convenient for users to store the product at home. During transportation, storing the feces collection box 20 inside the drum 30 can also protect it from external impact and extrusion, reducing physical damage that may occur during transportation.

[0094] In addition, the box body 21 is connected to the base 10 by a buckle (not shown), and the buckle connection method is simple and intuitive, and the disassembly and assembly operation can be completed without tools. The user can easily disassemble and reinstall the feces collecting box 20, which is convenient for cleaning and replacing parts. The buckle can be a press buckle, an elastic buckle 412 or a hook buckle, etc.

[0095] By designing the box body 21 to be detachably connected to the base 10 and to be switchable between an installed state and a stored state, this design not only improves the transportation and storage convenience of the cat litter box 100, but also enhances the user experience and optimizes the performance of the device.

[0096] In some other embodiments, the cross-section of the drum 30 is semicircular, the drum 30 has a curved surface 37 and a flat surface 38 , the second opening 3111 is disposed on the flat surface 38 of the drum 30 , and the outlet 34 is disposed on the curved surface 37 of the drum 30 .

[0097] like Figure 2 One side of the drum 30 is completely open, forming a larger entrance 36, which is convenient for the cat to enter and exit freely, reducing the sense of obstruction when the cat enters and exits. The larger opening allows the user to more easily access the inside of the drum 30 for thorough cleaning and inspection, thereby improving cleaning efficiency. The curved surface 37 is designed as the outlet 34, ensuring that the separated feces can fall directly into the feces ball temporary storage bin 33 under the action of gravity, reducing the possibility of scattering.

[0098] In addition, if Fig.11 The cover 22 is rotatably connected to the box body 21. Fig.11 and Fig.12 The outlet 34 between the feces collecting box 20 and the drum 30 and the collecting port 201 form a defecation channel. Since the cover body 22 is rotatably connected to the box body 21, the cover body 22 can be turned over. Therefore, when the cat stretches out of the drum 30 and the cat's body or cat's paws are stuck between the drum 30 and the cover body 22, the cover body 22 can be turned over together, so that the cat has room to move, and the cat can easily pull out the stuck cat's feet to avoid being fixed and clamped.

[0099] That is, when the cat extends from the opening of the drum 30 and contacts the feces collecting box 20, if it is stuck, the rotatable cover 22 will rotate when it feels pressure, and the cover 22 can flexibly adjust its position according to the cat's movements, providing a buffer mechanism, thereby releasing pressure on the cat and preventing the cat from being hurt. Furthermore, the cat may feel scared or nervous because of being stuck, and then react more violently. The rotatable cover 22 reduces the occurrence of this situation, allowing the cat to escape without causing greater harm, reducing the possibility of stress response. The above design can increase the reliability of the cat litter box 100 and improve the user experience.

[0100] The rotatable cover 22 makes it easier to open the feces collection box 20 for cleaning, which is convenient for the owner to regularly clean the feces collection box 20, simplifies the daily maintenance process, and is also convenient for cleaning, maintaining good sanitary conditions.

[0101] By setting the cover body 22 to be rotatable, when the cat extends from the opening of the drum 30 to between the drum 30 and the cover body 22 and gets stuck, the cover body 22 can rotate relative to the box body 21 after being subjected to force, so that the cat can easily pull out the stuck cat feet or cat body, etc., to prevent safety accidents.

[0102] In an embodiment of the present invention, the cover 22 includes a main body 221 and a flip cover 222 . The main body 221 is detachably connected to the box body 21 . The flip cover 222 is rotatably connected to the main body 221 . The flip cover 222 is spaced apart from the box body 21 and forms a collecting port 201 .

[0103] In detail, the detachable connection between the main body 221 and the box body 21 makes the feces collecting box 20 easier to clean. The detachable connection can be a snap connection or a threaded connection. Fig.11 The front end of the cover 22 is set to be rotatable, while the main body 221 remains fixed, reducing unnecessary shaking. The design of the flip cover 222 allows it to rotate when under pressure, thereby protecting the cat from harm. When the cat accidentally puts its claws or other parts of its body into the collection port 201 and feels blocked, the flip cover 222 can respond quickly and rotate, providing immediate space for movement and preventing the cat from being fixed and clamped.

[0104] In an embodiment of the present invention, the cover body 22 further includes a rotating shaft (not shown) and a torsion spring (not shown), the rotating shaft is fixedly connected to the body 221, the flap 222 is rotatably connected to the rotating shaft, the torsion spring is sleeved outside the rotating shaft, and one end of the torsion spring is connected to the flap 222. Specifically, by setting the rotating shaft and the torsion spring to connect the flap 222, the rotating shaft allows the flap 222 to rotate freely when subjected to external force, and the torsion spring makes the rotation of the flap 222 softer and smoother, ensuring that the flap 222 can rotate flexibly to avoid pinching the cat. At the same time, the torsion spring provides a restoring force, so that the flap 222 can naturally return to the initial position when there is no external force, ensuring the size of the collection port 201, and facilitating the discharge of the feces 200 into the feces collection box 20 in the defecation state, maintaining the consistency of the working state of the device, and reducing the need for manual adjustment by the user.

[0105] In the embodiment of the present invention, the flip cover 222 rotates relative to the body 221 and has an initial position. The flip cover 222 rotates up and down along the height direction of the base 10 relative to the initial position. The rotation angle of the flip cover 222 relative to the initial position is 30 degrees.

[0106] It is worth noting that Fig.11, the initial position of the flap 222 is in the middle, the flap 222 can rotate up and down relative to the initial position, and the angle of rotation up and down relative to the initial position is set to 30 degrees, that is, the rotation angle range of the flap 222 is 60 degrees, which can provide sufficient activity space for the cat and reduce the risk of the cat being pinched. And it is ensured that even if the flap 222 is not excessively opened or closed, the spring can provide an effective restoring force within a certain range, so that the flap 222 can quickly and accurately return to the initial position after each operation, so as to ensure that the flap 222 can stably return to the initial position, reducing the defecation problem caused by the improper position of the flap 222. At the same time, the 60-degree rotation angle of the flap 222 makes the movement range of the flap 222 smaller, keeping the appearance of the device neat and compact.

[0107] In the embodiment of the present invention, the outer side wall 16 of the cover body 22 is arranged in an arc shape. Figure 3 The outer side wall 16 of the cover 22 is designed with an arc surface, and the arc surface can better adapt to the circular contour inside the drum 30, making full use of the limited space, so that the cover 22 can fit the internal space of the drum 30 more closely, reducing the overall occupied volume, and the entire feces collection box 20 can be placed more compactly in the accommodating cavity 311 of the drum 30 in the storage state. And the rounded edge of the cover 22 will not easily scratch or hit pets or people like sharp right angles, and the arc corners reduce the risk of accidental injury to cats and other family members.

[0108] In the embodiment of the present invention, a collecting tank 12 is provided at the bottom of the base 10, and a protective net 13 is provided at the opening of the collecting tank 12. Fig.11 and Fig.13 The bottom of the base 10 is provided with a collecting trough 12 for collecting the fine kitten litter particles that cannot be completely separated during the screening process, so as to ensure that they will not be scattered on the ground, and keep the environment clean. When the drum 30 rotates, if a cat reaches into the collecting trough 12, it will be sandwiched between the drum 30 and the collecting trough 12. Therefore, by providing a protective net 13, the cat's body and feet are prevented from falling into the collecting trough 12, and the drum 30 rotates when the cat is at the bottom of the base 10 to prevent the cat from being sandwiched.

[0109] In an embodiment of the present invention, the base 10 and the protective net 13 are integrally formed. Specifically, the base 10 and the protective net 13 are integrally formed so that the base 10 and the protective net 13 become a solid whole, thereby enhancing the stability of the structure and improving the overall strength and durability of the base 10. At the same time, the manufacturing process can be simplified, the assembly steps can be reduced, and the protective net 13 can be seamlessly connected to the base 10. Users do not have to worry about the protective net 13 falling off or shifting, providing a more intuitive and reliable use experience.

[0110] The present invention also provides a feces collection method for the cat litter box 100 as described above, the feces collection method comprising: controlling the drum 30 to rotate relative to the base 10 to form relative position information of the first opening 14 and the second opening 3111; and controlling the outlet 34 of the feces temporary storage bin 33 to be connected or disconnected with the feces collection box 20 according to the relative position information.

[0111] Specifically, the opening or closing of the outlet 34 is controlled according to the relative position information between the first opening 14 and the second opening 3111 to ensure the consistency and reliability of each separation and defecation process.

[0112] The specific method of controlling the rotation of the drum 30 relative to the base 10 is to send instructions through the main control board system, and the motor drives the drum 30 to rotate, so that the second opening 3111 of the drum 30 and the first opening 14 of the base 10 are relatively displaced from the corresponding setting (that is, located on the same plane 38) to the staggered setting, so that the rotation position of the drum 30 can be known, and according to the relative position information, the outlet 34 of the feces temporary storage bin 33 can be controlled to be connected or disconnected with the feces collection box 20, so as to complete the separation of cat litter and feces 200, and complete the collection of feces 200.

[0113] By precisely monitoring the position of the drum 30, the system can accurately decide when to open or close the outlet 34 of the temporary storage bin 33 for feces, thus avoiding misoperation. The motor drive can achieve very fine angle adjustment, ensuring the consistency and reliability of each action, and the motor drive is usually smoother than manual operation, reducing the noise generated when the equipment is running. The entire process is automatically completed by the control system without manual intervention. The user only needs to clean the feces collection box 20 regularly without frequently adjusting the equipment status, saving time and energy. The closed design and timely collection of feces 200 help reduce the spread of odor and bacterial growth, and keep the internal environment clean.

[0114] In addition, the working mode can be flexibly adjusted according to different usage requirements. For example, the separation frequency can be increased during peak hours when cats frequently use the device, while the number of operations can be reduced during off-peak hours to meet the needs of different time periods. The main control board system can record and analyze operating data and provide users with information about the operating status of the device, which helps users understand the working efficiency of the device, identify potential problems in a timely manner, and perform necessary maintenance.

[0115] In an embodiment of the present invention, the steps of controlling the drum 30 to rotate relative to the base 10 to form relative position information of the first opening 14 and the second opening 3111 include: controlling the drum 30 to rotate relative to the base 10 along a first direction to form a first position, and the cat litter in the accommodating chamber 311 is discharged into the cat litter temporary storage bin 32; controlling the drum 30 to continue to rotate relative to the base 10 along the first direction to form a second position, and the feces in the accommodating chamber 311 is discharged into the feces ball temporary storage bin 33; controlling the drum 30 to rotate relative to the base 10 in the opposite direction of the first direction to form a third position, and the outlet 34 is connected to the feces collecting box 20, and the feces in the feces ball temporary storage bin 33 is discharged into the feces collecting box 20.

[0116] In detail, the first position and the second position are the positions of the drum 30 in the screening state, and the third position is the position of the drum 30 in the defecation state; when the drum 30 rotates in the first direction, in the first position, the drum 30 first discharges the cat litter into the cat litter temporary storage bin 32 through the screening holes 3531, ensuring the cleanliness of the cat litter, and the feces are screened outside the cat litter temporary storage bin 32; when the drum 30 continues to rotate to the second position, the feces flows into the feces ball temporary storage bin 33 under the action of gravity for temporary storage. An efficient screening process is achieved, which can efficiently separate cat litter from feces, retain clean cat litter to the maximum extent, discharge feces in a timely and effective manner, and keep the inside of the cat litter box 100 clean.

[0117] After the feces 200 are collected and temporarily stored, the drum 30 rotates in the opposite direction of the first direction, and the feces 200 gradually flows into the bottom of the feces temporary storage bin 33. When the drum 30 is located at the third position, the feces temporary storage bin 33 is higher than the feces collection box 20 in the height direction, and the control outlet 34 is connected to the feces collection box 20, so that the feces 200 in the feces temporary storage bin 33 can be directly discharged into the feces collection box 20. The opportunity for odor and bacteria to grow is reduced, a good sanitary environment is maintained, and the entire process is automated, reducing the risk of users contacting feces.

[0118] The first direction can be clockwise or counterclockwise, such as Fig.11 In this embodiment, the first direction is clockwise.

[0119] This specific method operates in sequence and separates step by step: the cat litter and feces are separated and collected step by step through three steps (first position, second position, third position), ensuring that the tasks at each stage are clear and efficient. This sequential operation can maximize the use of gravity and screening mechanisms, reduce the possibility of material mixing, and improve the separation effect.

[0120] In an embodiment of the present invention, the step of controlling the outlet 34 of the feces ball temporary storage bin 33 to be connected or disconnected with the feces collecting box 20 according to the relative position information includes: when the drum 30 is in the first position, the outlet 34 of the feces ball temporary storage bin 33 is controlled to be closed; when the drum 30 is in the second position, the outlet 34 of the feces ball temporary storage bin 33 is controlled to be closed; when the drum 30 is in the third position, the outlet 34 of the feces ball temporary storage bin 33 is controlled to be open.

[0121] It is worth noting that the drum 30 controls the outlet 34 to be closed in the first position and the second position, that is, in the screening state of the drum 30, the outlet 34 is controlled to be closed, ensuring that no feces accidentally flow out during the cat litter separation process, ensuring the closure during the feces collection process, ensuring the purity of the screening process, and avoiding material mixing. When the drum 30 is in the third position, that is, in the defecation state of the drum 30, the outlet 34 is controlled to be open for defecation, ensuring that the feces can be smoothly discharged into the feces collection box 20, and completing the final collection work.

[0122] The outlet 34 of the temporary storage bin 33 can be opened and closed by an electrically or manually driven sliding door 42, or by a pneumatic or hydraulic mechanism that can be used to push a piston to control the opening and closing of the door.

[0123] In this embodiment, if Fig.12 , the electromagnet 43 generates a magnetic field through the current to attract or release the sliding door 42, so as to control the opening and closing of the outlet 34 of the temporary storage bin 33 of the feces ball. The specific method is: the sliding door 42 normally closes the outlet 34, and the electromagnet 43 is installed on the base 10. When the sliding door 42 needs to be opened, the drum 30 rotates from the second position to the third position. During this process, the sliding door 42 gradually approaches the position of the electromagnet 43. When it reaches the position of the electromagnet 43, the electromagnet 43 is energized to attract the sliding door 42, and the drum 30 continues to rotate to the third position. The sliding door 42 is attracted by the electromagnet 43 to generate reverse friction. The sliding door 42 slides relative to the drum 30 and gradually opens the outlet 34. Therefore, when the drum 30 reaches the third position, the outlet 34 is opened, and the feces ball 200 can directly fall into the rear feces collecting box 20 through the outlet 34.

[0124] In an embodiment of the present invention, before controlling the drum 30 to rotate relative to the base 10 to form the relative position information of the first opening 14 and the second opening 3111, the step of controlling the drum 30 to be stationary relative to the base 10, the first opening 14 corresponds to the second opening 3111, and the outlet 34 of the feces temporary storage bin 33 is disconnected from the feces collecting box 20.

[0125] In detail, Fig. 9, the drum 30 is stationary relative to the base 10, and the first opening 14 corresponds to the second opening 3111. At this time, the outlet 34 of the temporary storage bin 33 is closed, which is convenient for the cat to use. This is the use state of the cat litter box 100. The cat can enter the accommodating cavity 311 of the drum 30 from the second opening 3111 to go to the toilet. The drum 30 is in a stationary state, avoiding potential damage to the cat caused by rolling. In the use state, the outlet 34 of the temporary storage bin 33 is closed to effectively prevent cat litter and feces from accidentally flowing out.

[0126] Cats can use the litter box 100 in a comfortable environment, and users can enjoy a more convenient and reliable operation experience. By first stopping the drum 30 and closing the outlet 34, the system can ensure that all conditions are ready before starting the separation, thereby improving the efficiency of the entire process.

[0127] A gravity sensing mechanism, a radar mechanism and an infrared system are set up to detect that after the cat defecates, the cat feces and the cat litter are agglomerated after a few minutes, and the main control system issues a command to start the machine to drive the drum 30 to rotate, and the drum 30 rotates 200° clockwise to Fig.11 As shown in the position, the third screening element 353 is rotated to a position greater than 90° along the vertical direction. During this process, the cat litter leaks through the screening holes 3531 of the third screening element 353 and enters the cat litter temporary storage bin 32. The cat feces balls stained with cat litter are located outside the third screening element 353 and roll into the feces ball temporary storage bin 33 along the surfaces of the third screening element 353 and the second screening element 352.

[0128] In an embodiment of the present invention, after controlling the outlet 34 of the feces temporary storage bin 33 to be connected or disconnected with the feces collection box 20 according to the relative position information, the step of controlling the drum 30 to rotate relative to the base 10 so that the first opening 14 corresponds to the second opening 3111, and the outlet 34 of the feces temporary storage bin 33 is disconnected from the feces collection box 20.

[0129] It is worth noting that after the feces 200 are discharged into the feces collecting box 20, the sliding door 42 needs to be controlled to close and restore to the initial state to prepare for the next use.

[0130] In this embodiment, after excrement is discharged, the main control board system instructs the drum 30 to drive the motor to rotate clockwise by a certain angle (25.5° in this embodiment), and the slide rail 41 on the drum 30 moves relative to the sliding door 42 to a track position close to the outlet 34, and the clamping shaft 422 on the sliding door 42 is clamped into the elastic clamping groove 4121 of the slide rail 41. The main control system sends another instruction to stop supplying power to the electromagnet 43, and the electromagnet 43 has no suction force. The sliding door 42 is located at a track position of the slide rail 41 close to the outlet 34, closing the outlet 34, and the drum 30 rotates counterclockwise to return to its original position, and the sliding door 42 moves synchronously with the drum 30.
