[0030] In addition to the need for cleaning after the kitten excretes and screening and processing the excrement, the cat litter in the cat litter box also needs to be replaced regularly to ensure the cleanliness of the cat litter box and the health and safety of the kitten using the cat litter. Most of the existing intelligent cat litter boxes are provided with an automatic cleaning function to clean the excrement, but few of them are provided with an automatic cat litter cleaning function, that is, the user still needs to manually clean the cat litter in the cat litter box during the sand replacement operation, which is complicated. Therefore, there is an urgent need for a cat litter box with an automatic cat litter cleaning function to automatically clean the cat litter in the cat litter box, reduce the operation steps required by the user for sand replacement, and make the cat litter box more convenient to use.
[0031] In view of this, the present application provides a cat litter box, Figures 1 to 5 An embodiment of the cat litter box provided by the present application will be described below in combination with specific drawings.
[0032] Referring to Figures 1 to 5 The cat litter box 100 comprises a main body 1, at least one movable bottom plate 3 and a driving device 4, the main body 1 is provided with a cavity 11, a box 2 for containing cat litter is installed in the cavity 11, and the bottom of the box 2 is provided with an opening; the movable bottom plate 3 is movably installed on the main body 1 and covers the opening to carry cat litter; the driving device 4 is installed on the main body 1 and drives the movable bottom plate 3 to move, so that the movable bottom plate 3 has a discharging state of moving to expose the opening and a carrying state of covering the opening.
[0033] In the technical scheme, the box 2 is arranged in the main body 1 of the cat litter box 100, the bottom of the box 2 is provided with an opening, and then the movable bottom plate 3 is arranged at the opening; when the movable bottom plate 3 is in the carrying state of covering the opening, the box 2 contains cat litter, and the movable bottom plate 3 carries cat litter to avoid the cat litter from leaking out of the opening; at this time, the cat litter box 100 can be normally used by kittens. When it is necessary to perform a sand cleaning operation, the driving device 4 drives the movable bottom plate 3 to move away from the opening, the cat litter carried on the movable bottom plate 3 is no longer supported by the movable bottom plate 3, and thus is discharged from the opening, and then the movable bottom plate 3 is restored to the carrying state of covering the opening, the sand cleaning operation is completed, and the operation is convenient and fast. In addition, the box 2 is arranged in the main body 1 to contain cat litter, the box 2 is detachably arranged, and thus is convenient to disassemble and clean; compared with directly using the main body 1 to carry cat litter, the cavity 11 can be better kept in a clean and sanitary state. Meanwhile, the movable bottom plate 3 and the driving device 4 are installed on the main body 1 and independently arranged on the box 2, and thus do not affect the disassembly operation of the box 2, and the box 2 is more convenient to disassemble and clean, the willingness of a user to clean is improved, and the clean and sanitary state of the cavity 11 can be better ensured.
[0034] It can be understood that the sand replacement step of the cat litter box 100 is: first, the movable bottom plate 3 in the carrying state is driven by the driving device 4 to move to the discharging state, during which the movable bottom plate 3 is exposed to the outlet, and the cat litter in the box 2 is discharged from the outlet, and the preset waiting time or the preset high-frequency movement control of the movable bottom plate 3 makes the movable bottom plate 3 shake the cat litter. At this time, the cat litter in the box 2 has been basically discharged, the driving device 4 drives the movable bottom plate 3 in the discharging state to move to the carrying state, and then new sand is added in the box 2 to complete the replacement of the cat litter in the box 2, which is convenient and fast. In addition, if it is necessary to clean the box 2, after the cat litter is completely discharged, the movable bottom plate 3 is in the discharging state, that is, the opening is in the exposed state, which facilitates the box 2 to be detached from the main body 1, and after cleaning, it is reloaded and then the driving device 4 drives the movable bottom plate 3 to return to the carrying state to cover the opening, thereby completing the cleaning of the box 2.
[0035] Specifically, the movable bottom plate 3 is rotatably installed on the main body 1, and the driving device 4 is configured to drive the movable bottom plate 3 to rotate. The movable bottom plate 3 can be horizontally movable and installed on the main body 1. When the driving device 4 drives the movable bottom plate 3 to horizontally move, the movable bottom plate 3 is translated away from the opening to expose the opening, and the movable bottom plate 3 is accommodated under the box 2 when it is translated. The cat litter carried on the movable bottom plate 3 is scraped by the edge of the opening at the bottom of the box 2 to avoid the cat litter being taken away when the movable bottom plate 3 is accommodated under the box 2, which causes the cat litter on the movable bottom plate 3 to be not cleaned completely, thereby avoiding affecting the cleaning degree of the surface of the movable bottom plate 3. This arrangement can realize the carrying state and the unloading state of the movable bottom plate 3, and also meets the structural and functional requirements of the present application. However, when the movable bottom plate 3 is accommodated in the box 2, a certain accommodation space needs to be preset, and the accommodation space needs to be large enough to accommodate the entire movable bottom plate 3, which can cause the overall volume of the cat litter basin 100 to be too large, which is inconvenient to use. Therefore, in the present embodiment, the movable bottom plate 3 is rotatably installed on the main body 1, and the driving device 4 is configured to drive the movable bottom plate 3 to rotate to realize the carrying state and the unloading state of the movable bottom plate 3. In the unloading state, the movable bottom plate 3 is in an inclined state, and the cat litter is rolled off the inclined surface of the movable bottom plate 3, so as to ensure the cleaning degree of the surface of the movable bottom plate 3. At the same time, the movable bottom plate 3 does not translate, and the space above the movable bottom plate 3 is the accommodation cavity of the box 2, and the space below the movable bottom plate 3 is the unloading channel of the cat litter. The rotation of the movable bottom plate 3 does not require additional space, that is, it does not increase the volume of the cat litter basin 100. Compared with the above-mentioned horizontally movable movable bottom plate 3, the arrangement in the present embodiment reduces the volume of the cat litter basin 100, which is more convenient for use in a family space. Of course, without considering the volume, the above-mentioned horizontally movable movable bottom plate 3 can also be used, which is not limited herein.
[0036] Specifically, the movable bottom plate 3 comprises at least two side plates 31 arranged at opposite sides of the box 2, and the driving device 4 drives the two side plates 31 to rotate towards the middle part of the box 2, so that the cat litter is discharged towards the middle part of the box 2. The movable bottom plate 3 in the embodiment is rotatably installed on the main body 1, as described above. It is conceivable that the fewer the number of the movable bottom plate 3, the larger the size of the movable bottom plate 3, so that the height of the cavity 11 required for rotation and the height of the discharge space are larger. In the embodiment, the movable bottom plate 3 is arranged as three, and the two side plates 31 close to the edges of the box 2 are arranged to rotate oppositely, i.e., the side close to the edge of the box 2 is upwardly rotated, so that the two sides close to the middle part of the opening are downwardly rotated, and the cat litter is discharged in the middle part, which is convenient for collecting the cat litter at the lower part of the opening. It is understood that the movable bottom plate 3 can be arranged as two side plates 31 side by side, and an additional fixed bottom plate structure can be arranged between the two side plates 31 to assist the side plates 31 in covering the opening, or no additional arrangement is required, and the covering of the opening is completed by the two side plates 31 in the bearing state. Of course, the movable bottom plate 3 can be arranged as multiple, not limited to three in the embodiment, and whether an additional fixed bottom plate structure is arranged between adjacent movable bottom plates 3 is not limited. In summary, the two side plates 31 are arranged side by side and spaced apart, and whether an additional fixed bottom plate structure is arranged between the two side plates 31 and the structure of the movable bottom plate 3 are not limited.
[0037] In addition, the edge of the side plate 31 close to the box 2 is upwardly raised to fit the inner wall of the box 2. In order to avoid the gap between the side plate 31 and the box 2 being too large, causing the cat litter to escape from the gap, the edge of the side plate 31 close to the box 2 is upwardly raised to form an arc surface fitting the inner wall of the box 2. When the side plate 31 returns to the state of covering the opening, the arc surface at the edge of the side plate 31 is pressed and fitted to the box 2 by the gravity of the side plate 31 itself and the cat litter, thereby closing the gap between the box 2 and the side plate 31, and avoiding the escape of cat litter from the gap.
[0038] In addition, the box 2 extends downward corresponding to two sides of the side plate 31, and is inclinedly arranged towards the middle part thereof to form a guide part 21. The guide part 21 is formed in a funnel structure in cross section to concentrate the cat litter for unloading. The guide part 21 is arranged in cooperation with the rotating direction of the side plate 31 to concentrate the cat litter, and when the side plate 31 rotates, if there is cat litter escaping from the edge thereof and the box 2, the escaping cat litter can be guided by the guide part 21 to concentrated unloading, which facilitates concentrated collection, and avoids the cat litter from falling into the cat litter basin 100, which causes the cat litter basin 100 to be difficult to clean.
[0039] In addition, the driving device 4 includes a jacking structure 41 arranged corresponding to below the movable bottom plate 3. The jacking structure 41 is arranged to be movable up and down, so that the jacking structure 41 upwardly abuts against the bottom of the movable bottom plate 3 to drive the movable bottom plate 3 to rotate. The movable bottom plate 3 is rotatably installed on the main body 1, which has been described in detail above. The driving device 4 is used to drive the movable bottom plate 3 to rotate. It is easily conceivable that the driving device 4 can be directly arranged as a rotating motor connected to the rotating shaft of the movable bottom plate 3, but when the movable bottom plate 3 carries cat litter, the rotating motor needs larger power to drive the movable bottom plate 3 to rotate. In the embodiment, the driving device 4 is arranged as the jacking structure 41 movable up and down, so that the required driving power thereof is smaller, and when the jacking structure 41 jacks the movable bottom plate 3, it also plays a role of abutting support, so that the rotating height of the movable bottom plate 3 is more stable. It can be understood that the jacking structure 41 can have various embodiments, including but not limited to a crank and connecting rod structure, a linear driving structure, etc. It is only required to ensure that the jacking structure 41 has an up and down movement stroke to abut against the movable bottom plate 3 to realize the rotating function thereof. In addition, the up and down movement manner of the jacking structure 41 is not limited to vertical up and down, and it is only required to ensure that there is an up and down direction movement.
[0040] Further, the driving device 4 further comprises a driving link 42 arranged below the jacking structure 41, and a convex portion 421 is arranged on the driving link 42 corresponding to each jacking structure 41. The driving link 42 is movable to make the bottom end of the jacking structure 41 move between the bottom and top of the convex portion 421, so that the convex portion 421 pushes the jacking structure 41 to move up and down. The driving device 4 can be provided with multiple driving members to drive each jacking structure 41 to jack the movable floor 3. The structure is relatively simple, but it is difficult to keep multiple driving members in synchronous driving state, and the adjacent movable floors 3 may be affected by each other. In addition, the cost of setting multiple driving members is relatively high. In the embodiment, one driving link 42 is arranged, and the driving link 42 is driven to move by one driving member to synchronously drive multiple movable floors 3. The cost is relatively low, and multiple movable floors 3 are synchronously driven. Specifically, the driving link 42 is provided with a convex portion 421 corresponding to each movable floor 3. When the driving link 42 moves horizontally, the convex portion 421 can move close to or away from the jacking structure 41. When the convex portion 421 contacts the jacking structure 41, the jacking structure 41 can be moved between the bottom and top of the convex portion 421 by continuously driving the driving link 42, so as to move up and down, thereby driving the movable floor 3 to rotate and achieving the operation of discharging the cat litter.
[0041] Further, the driving device 4 further comprises a driving gear 43 arranged at one end of the driving link 42, and a rack structure 422 is arranged corresponding to the driving link 42. The driving gear 43 rotates to act on the rack structure 422 to drive the driving link 42 to move. The driving mode of the driving link 42 can be to arrange a linear driving member to directly drive, such as a gas rod, a telescopic rod, etc. However, this driving mode has the problem that the driving distance is not easy to control. If it is necessary to accurately control the driving distance, the cost is relatively high. Therefore, in the embodiment, one end of the driving link 42 is arranged as the rack structure 422, and a driving gear 43 is arranged to cooperate with the rack structure 422. The driving gear 43 rotates to push the rack structure 422 to drive the driving link 42 to move. The rotation angle or rotation number of the driving gear 43 can be converted into the movement distance of the driving link 42 in a certain proportion, so as to accurately control the movement of the driving link 42, which is mature in technology and low in cost.
[0042] Further, at least one of the top end and the bottom end of the jacking structure 41 is provided with a rolling structure 411. The top of the jacking structure 41 abuts against the movable bottom plate 3, the bottom of the jacking structure 41 abuts against the driving link 42, and when the jacking structure 41 is in motion, there is relative displacement between the movable bottom plate 3 and the driving link 42, that is, there is wear and sliding friction resistance, which does not affect its own function, but causes large energy loss and short service life. Therefore, in the embodiment, the rolling structure 411 is arranged at at least one of the top end and the bottom end of the jacking structure 41 to solve the above problems. Specifically, the rolling structure 411 is arranged at the top end and the bottom end of the jacking structure 41.
[0043] In addition, a plurality of movable bottom plates 3 are provided, and adjacent movable bottom plates 3 are stacked up and down at their junctions. The number of movable bottom plates 3 can be multiple, and in the embodiment, three are provided, which have been described above and will not be described again. Specifically, if there is a gap between two movable bottom plates 3, cat litter will escape along the gap, affecting the use experience of the cat litter basin 100. Therefore, in the embodiment, in combination with the rotation of each movable bottom plate 3, the junctions of two adjacent movable bottom plates 3 are arranged in a stacked up and down state, that is, the movable bottom plates 3 in the bearing state are stacked with one movable bottom plate 3 on another movable bottom plate 3, so that the two movable bottom plates 3 are tightly abutted, so that there is no gap between them, or cat litter is not easy to escape, thereby solving the problem of cat litter escaping.
[0044] In addition, the box 2 is buckled to the inner wall of the cavity 11. The box 2 is detachably connected to the main body 1 to facilitate removal for cleaning, which has been described above. If the box 2 is not fixed when installed to the main body 1, it is only stabilized by the weight of the cat litter. When the movable bottom plate 3 rotates, the movable bottom plate 3 may drive the box 2, affecting the fit of the box 2 with the movable bottom plate 3 and the main body 1, and then a gap is formed, causing cat litter to escape. Therefore, in the embodiment, a buckle structure 5 is arranged between the main body 1 and the box 2 to buckle the box 2 to the main body 1, achieving detachable arrangement while stabilizing the box 2.
[0045] In addition, the bottom of the cavity 11 is provided with a collecting device 6, and the collecting device 6 is located below the opening to collect the discharged cat litter. When the cat litter basin 100 needs to be replaced, the cat litter basin 100 can be moved above a garbage can or other storage device, and the movable bottom plate 3 is operated to discharge the cat litter, so that the collecting device 6 is not required, the cost of the cat litter basin 100 is reduced, but the operation is obviously more inconvenient. Therefore, in the embodiment, the collecting device 6 is arranged below the box 2, and the opening corresponds to the collecting device 6. When the movable bottom plate 3 is rotated to the discharging state, the cat litter is discharged from the opening to the collecting device 6, without moving the cat litter basin 100, and the operation is automatic and does not require manual operation. Only the old cat litter in the collecting device 6 needs to be disposed of after the cat litter is replaced, which is convenient to operate.
[0046] Specifically, the collecting device 6 includes a collecting box 61 which can be pulled out laterally from the main body 1. The collecting device 6 is provided as the collecting box 61 which can be detached. On the one hand, cat litter is not feces of cats, and has no strong odor, so that it does not need to be odor-proof, i.e. it does not need to be packaged, and can be manually emptied. On the other hand, the collecting box 61 is arranged as a drawer, so that it does not affect the function of the cat litter basin 100, i.e. it does not affect the normal use of the cat litter basin 100 when the collecting box 61 is taken out for emptying. In addition, this arrangement is practical and low in cost.
[0047] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, which is made based on the inventive concept of the present application and the content of the specification and drawings, is included in the patent protection scope of the present application.
