Description

Technical Field

[0001] This utility model relates to the field of pet cleaning technology, and in particular to a cat litter box. Background Technology

[0002] Most current pet toilets are ordinary containers, such as litter boxes, filled with cat litter for pets to use for defecation. However, after a pet defecates, the odor of the excrement in the litter box is very pungent and unacceptable. For example, patent application CN219578033U discloses a litter box that includes a base, a litter box mounted on the base, and a drive mechanism for rotating the litter box. The litter box includes a box body, a litter sieve plate, a litter collection box, and a litter collection container. In this litter box, the odor of excrement in the litter collection box leaks into the air, causing unpleasant smells and affecting the user experience. Utility Model Content

[0003] To address the aforementioned technical problems in the existing technology, this utility model provides a cat litter box that can seal the upper opening of the feces chamber component connected to the rotating space, preventing the odor of excrement inside the feces chamber component from leaking into the air, thus preventing odor from escaping and improving the user experience.

[0004] This application provides a cat litter box, including:

[0005] A base is provided with a rotatably mounted ball chamber assembly, and there is a rotation space between the bottom of the ball chamber assembly and the base. The base is provided with a first magnetic element corresponding to the rotation space.

[0006] A commode assembly is mounted on the base, and a ball commode assembly is located above the commode assembly. The upper opening of the commode assembly is connected to the rotation space.

[0007] A sealing assembly, located at the bottom of the sump assembly, includes a sealing element and a second magnetic element for moving the sealing element. The first and second magnetic elements attract each other under their respective magnetic fields. The sealing element is circumferentially positioned within the rotation space around the bottom of the sump assembly. When the sump assembly rotates to a preset angle where the first and second magnetic elements approach each other, the second magnetic element, under the attraction of the first magnetic element, drives the sealing element against the base, thereby sealing the bottom of the sump assembly and the base circumferentially. This structure seals the upper opening of the sump assembly, which communicates with the rotation space, preventing the odor of excrement inside the sump assembly from leaking into the air, thus preventing odor emission and improving the user experience.

[0008] In some embodiments, the sealing assembly further includes an elastic element that acts on the seal to apply a force to the seal, moving it away from the base. Thus, by having the elastic element act on the seal when the first and second magnetic elements are far apart, the seal can be moved away from the base, achieving seal repositioning.

[0009] In some embodiments, the bottom of the ball housing assembly has a recess, and the seal is at least partially located within the recess. This allows for stable installation of the seal through the recess.

[0010] In some embodiments, the bottom of the ball chamber assembly is provided with a connection hole, and the seal is provided with a connecting post facing the bottom of the ball chamber assembly, the connecting post being inserted into the connection hole. Thus, the seal can be stably installed on the bottom of the ball chamber assembly through the cooperation of the connecting post and the connection hole, ensuring the installation stability of the seal.

[0011] In some embodiments, the connecting post is provided with a mounting hole, and the sealing assembly further includes a threaded connector provided on the mounting hole. The elastic element is sleeved on the connecting post, with one end of the elastic element abutting against the ball chamber assembly and the other end abutting against the threaded connector, so as to act on the sealing element through the threaded connector. Thus, the second magnetic element can drive the sealing element to move stably through the mounting hole and the threaded connector provided on the mounting hole. The above structure is compact and reasonable.

[0012] In some embodiments, multiple second magnetic elements are arranged circumferentially around the seal, with each second magnetic element corresponding to a first magnetic element. Thus, the cooperation of multiple second magnetic elements and the first magnetic element improves the sealing performance of the seal over the rotational space, thereby further ensuring that odors within the toilet chamber assembly do not leak out.

[0013] In some embodiments, one of the first and second magnetic components is constructed as a magnet, and the other is constructed as an iron block. Thus, the sealing component can be stably moved by the attraction between the first and second magnetic components. The first and second magnetic components have simple structures and low installation costs.

[0014] In some embodiments, the base is provided with a mounting bracket, and the first magnetic component is mounted on the base via the mounting bracket. This allows the magnetic component to be stably mounted on the base.

[0015] In some embodiments, the litter box further includes a drive component and a transmission assembly connected to each other. The drive component is mounted on the base, and the transmission assembly is connected to the ball chamber assembly. The drive component drives the ball chamber assembly to rotate via the transmission assembly. This ensures stable movement of the ball chamber assembly by driving the transmission assembly and the ball chamber assembly to rotate.

[0016] In some embodiments, the transmission assembly includes a meshing drive gear and a driven gear. The drive gear is mounted on the base and connected to the output shaft of the drive member. The driven gear is mounted on the ball chamber assembly, such that the drive member drives the ball chamber assembly to move via the drive gear and the driven gear. In this way, the drive member can stably drive the ball chamber assembly to move via the drive gear and the driven gear, ensuring the motion stability of the ball chamber assembly.

[0017] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: This utility model, through the sealing element of the sealing assembly and the second magnetic element used to drive the movement of the sealing element, enables the first and second magnetic elements to approach each other when the ball chamber assembly rotates to a preset angle. This allows the second magnetic element, under the attraction of the first magnetic element, to drive the sealing element against the base, thereby sealing the bottom of the ball chamber assembly and the base circumferentially. Specifically, it seals the rotational space between the bottom of the ball chamber assembly and the base, thus sealing the upper opening of the litter box assembly connected to the rotational space. This prevents the odor of excrement inside the litter box assembly from leaking into the air, preventing odor emission, improving the user experience, and maintaining the hygiene of the litter box. Furthermore, the method of using the magnetic attraction between the first and second magnetic elements to drive the movement of the sealing element has a simple structural design and low installation cost, which is conducive to the promotion of the litter box product.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This application provides a cat litter box. For example... Figures 1 to 8As shown, the litter box includes a base 1, a litter compartment assembly 3, and a sealing assembly 4. The base 1 has a rotatably mounted ball-shaped assembly 2, with a rotational space 11 between the bottom of the ball-shaped assembly 2 and the base 1. The base 1 has a first magnetic element 12 corresponding to the rotational space 11. The litter compartment assembly 3 is mounted on the base 1, with the ball-shaped assembly 2 located above it. The upper opening of the litter compartment assembly 3 communicates with the rotational space 11. The sealing assembly 4 is located at the bottom of the ball chamber assembly 2. The sealing assembly 4 includes a sealing element 41 and a second magnetic element 42 for driving the sealing element 41 to move. The first magnetic element 12 and the second magnetic element 42 attract each other under the action of their respective magnetic fields. The sealing element 41 is circumferentially arranged in the rotation space 11 around the bottom of the ball chamber assembly 2. When the ball chamber assembly 2 rotates to a preset angle where the first magnetic element 12 and the second magnetic element 42 are close together, the second magnetic element 42 drives the sealing element 41 to abut against the base 1 under the attraction of the first magnetic element 12, so as to seal the bottom of the ball chamber assembly 2 and the base 1 circumferentially through the sealing element 41.

[0032] like Figures 5 to 8 As shown, Figure 5 and Figure 6 The sealing assembly 4 shown is in a non-sealed state. One side of the non-sealed seal 41 is connected to the commode assembly 3, and the other side is away from the base 1, so that the rotation space 11 between the bottom of the commode assembly 2 and the base 1 is ventilated. Figure 7 and Figure 8 The sealing assembly 4 shown is in a sealed state. One side of the sealing member 41 in the sealed state is connected to the commode assembly 3, and the other side abuts against the base 1, so that the bottom of the commode assembly 2 and the base 1 are circumferentially sealed, thereby sealing the rotation space 11.

[0033] The aforementioned litter box may also include an odor-deodorizing and sterilizing component, which can be located inside the litter compartment assembly 3 or on the base 1 and communicate with the interior of the litter compartment assembly 3. The odor-deodorizing and sterilizing component is used to sterilize and deodorize the excrement and air inside the litter compartment assembly 3, preventing bacteria and odors from escaping from the litter compartment assembly 3 and improving the sterilization and deodorization effect. Specifically, the odor-deodorizing and sterilizing component may include an odor-deodorizing element and a sterilizing element. The odor-deodorizing element can use activated carbon adsorption to reduce odors inside the litter compartment assembly 3, while the sterilizing element may include an ultraviolet disinfection lamp, which can effectively kill bacteria and viruses in the air and on object surfaces, and is used for air disinfection around the litter box to help reduce the spread of bacteria.

[0034] The aforementioned ball chamber assembly 2 can adopt a roller design, which rotates to allow the excrement in the cat litter inside the ball chamber assembly 2 to fall into the feces chamber assembly 3. The feces chamber assembly 3 collects the excrement to facilitate the separation of the cat litter inside the ball chamber assembly 2 and the excrement inside the feces chamber assembly 3.

[0035] The rotation space 11 between the bottom of the ball chamber assembly 2 and the base 1 allows the ball chamber assembly 2 to rotate smoothly on the base 1. However, this also causes the odor of the excrement in the feces assembly 3 to overflow through the upper opening of the feces assembly 3 and the rotation space 11. By sealing the rotation space 11 between the bottom of the ball chamber assembly 2 and the base 1 with the sealing assembly 4, the upper opening of the feces assembly 3 can be sealed, thus solving the problem of the odor of the excrement in the feces assembly 3 overflowing outward.

[0036] Figure 7 The litter box assembly 2 shown is rotated to a preset angle. At this preset angle, the litter box is in normal working condition, and the cat can enter the litter box to defecate. The preset angle can be understood as the angle between the center line of the litter box assembly 2 and the vertical line when rotated clockwise. The preset angle can range from 10 degrees to 80 degrees.

[0037] The aforementioned sealing element 41 can move up and down relative to the base 1. When the first magnetic element 12 and the second magnetic element 42 are close together, the second magnetic element 42 can drive the sealing element 41 to move downward under the attraction of the first magnetic element 12 so as to abut against the base 1.

[0038] This invention utilizes a sealing element 41 in the sealing assembly 4 and a second magnetic element 42 for driving the movement of the sealing element 41. When the ball chamber assembly 2 rotates to a preset angle, the first magnetic element 12 and the second magnetic element 42 approach each other. Under the attraction of the first magnetic element 12, the second magnetic element 42 drives the sealing element 41 to press against the base 1, thereby sealing the bottom of the ball chamber assembly 2 and the base 1 circumferentially. This seals the rotation space 11 between the bottom of the ball chamber assembly 2 and the base 1, thus sealing the upper opening of the litter box assembly 3, which is connected to the rotation space 11. This prevents the odor of excrement in the litter box assembly 3 from leaking into the air, thus preventing odor emission, improving the user experience, and maintaining the hygiene of the litter box. Furthermore, the method of using the magnetic attraction between the first magnetic element 12 and the second magnetic element 42 to drive the movement of the sealing element 41 has a simple structural design and low installation cost, which is conducive to the promotion of litter boxes.

[0039] In some embodiments, such as Figures 3 to 8 As shown, the sealing assembly 4 also includes an elastic element 43, which acts on the sealing element 41 to apply a force to the sealing element 41 to move it away from the base 1.

[0040] Thus, the elastic element 43 can act on the seal 41 when the first magnetic element 12 and the second magnetic element 42 are far apart, so that the seal 41 can move away from the base 1 and reset the seal 41, so that the ball chamber assembly 2 can rotate stably relative to the base 1 and the rotation of the ball chamber assembly 2 will not be affected by the position of the seal 41.

[0041] The aforementioned elastic element 43 can be an elastic structure such as a spring or a sheet, and this application does not limit the specific structure of the elastic element 43.

[0042] The aforementioned elastic element 43 can be configured one-to-one with the second magnetic element 42, so that when the first magnetic element 12 and the second magnetic element 42 are far apart, the corresponding sealing element 41 can be driven to move away from the base 1 quickly, so that the ball chamber assembly 2 can rotate smoothly.

[0043] In some embodiments, such as Figure 3 As shown, the bottom of the ball chamber assembly 2 is provided with a cavity 21, and the seal 41 is at least partially located within the cavity 21. In this way, the seal 41 can be stably installed through the cavity 21.

[0044] The aforementioned cavity 21 can be constructed as an annular cavity, and the seal 41 can be located entirely or partially within the cavity 21.

[0045] In some embodiments, such as Figure 3 As shown, the bottom of the ball chamber assembly 2 is provided with a connection hole 22, and the sealing member 41 is provided with a connection post 44 facing the bottom of the ball chamber assembly 2. The connection post 44 is inserted into the connection hole 22.

[0046] In this way, the seal 41 can be stably installed at the bottom of the ball chamber assembly 2 through the cooperation of the connecting column 44 and the connecting hole 22, thus ensuring the installation stability of the seal 41.

[0047] There can be multiple connecting posts 44 and connecting holes 22, and the connecting posts 44 and connecting holes 22 can be set one-to-one to further enable the sealing element 41 to be stably installed at the bottom of the ball chamber assembly 2.

[0048] The connecting post 44 can be integrally formed with the sealing element 41 to ensure a relatively stable positional relationship between the connecting post 44 and the sealing element 41.

[0049] The aforementioned seal 41 can be made of a flexible material so that it can be more stably resisted by the base 1 through deformation, thereby effectively sealing the rotation space 11.

[0050] In some embodiments, such as Figures 3 to 8 As shown, the connecting post 44 is provided with a mounting hole, and the sealing assembly 4 also includes a threaded connector 45 provided on the mounting hole. The elastic member 43 is sleeved on the connecting post 44, and one end of the elastic member 43 abuts against the ball chamber assembly 2, and the other end abuts against the threaded connector 45, so as to act on the sealing member 41 through the threaded connector 45.

[0051] Thus, the second magnetic element 42 can drive the sealing element 41 to move stably through the mounting hole and the threaded connector 45 provided on the mounting hole. The above structure is compact and reasonable.

[0052] The aforementioned elastic element 43 can be constructed as a spring, which is sleeved outside the connecting post 44 and used to act on the sealing element 41 through the threaded connecting element 45.

[0053] The aforementioned threaded connector 45 may have a threaded connection portion and an abutment portion connected together. The threaded connection portion is threadedly connected to the mounting hole, and the abutment portion is located outside the mounting hole and abuts against the other end of the elastic member 43.

[0054] In some embodiments, such as Figures 3 to 8 As shown, multiple second magnetic elements 42 are arranged circumferentially around the sealing element 41, and the second magnetic elements 42 are arranged in a one-to-one correspondence with the first magnetic elements 12.

[0055] In this way, the sealing performance of the sealing member 41 for the rotation space 11 can be improved by the cooperation of multiple second magnetic members 42 and first magnetic members 12, thereby further ensuring that the odor in the toilet assembly 3 will not leak out.

[0056] The aforementioned multiple second magnetic elements 42 can be uniformly arranged around the seal 41 in a circumferential direction.

[0057] like Figure 3 As shown, Figure 3 The diagram shows four second magnetic elements 42 and four first magnetic elements 12, which are evenly arranged around the seal 41 to improve the sealing performance of the seal 41 for the rotation space 11. Of course, the number of second magnetic elements 42 and first magnetic elements 12 described above is merely an example; it is sufficient to ensure the sealing effectiveness for the rotation space 11.

[0058] In some embodiments, one of the first magnetic element 12 and the second magnetic element 42 is constructed as a magnet, and the other is constructed as an iron block. In this way, the sealing element 41 can be stably driven to move by the attraction between the first magnetic element 12 and the second magnetic element 42. The first magnetic element 12 and the second magnetic element 42 have simple structures and low installation costs.

[0059] The aforementioned second magnetic component 42 may specifically be a magnet, and its shape may be rectangular, cylindrical, or similar.

[0060] The first magnetic component 12 mentioned above can be a block of iron, and its shape can be rectangular, cylindrical, or other shapes.

[0061] In some embodiments, such as Figures 3 to 8 As shown, a mounting bracket 13 is provided on the base 1, and the first magnetic component 12 is mounted on the base 1 through the mounting bracket 13. In this way, the magnetic component can be stably mounted on the base 1.

[0062] The aforementioned mounting bracket 13 can be detachably connected to the base 1. A cavity can be formed inside the mounting bracket 13, and the first magnetic component 12 can be disposed in the cavity.

[0063] The shape of the cavity with the mounting bracket 13 can be adapted to the shape of the first magnetic component 12 to ensure stable installation of the first magnetic component 12.

[0064] In some embodiments, such as Figure 9 As shown, the litter box also includes a drive component 5 and a transmission assembly 6 connected to each other. The drive component 5 is mounted on the base 1, and the transmission assembly 6 is connected to the ball chamber assembly 2. The drive component 5 is used to drive the ball chamber assembly 2 to rotate through the transmission assembly 6.

[0065] In this way, the drive component 5 can drive the transmission component 6 and the ball chamber component 2 to rotate, ensuring the stable movement of the ball chamber component 2.

[0066] The aforementioned driving component 5 may include a drive motor, the output shaft of which is connected to a transmission assembly 6. The transmission assembly 6 may be partially located on the base 1 and partially located on the ball chamber assembly 2, so as to drive the ball chamber assembly 2 to rotate stably through the transmission assembly 6.

[0067] The aforementioned transmission component 6 may be one or a combination of the following structures: lead screw and nut structure, worm gear structure, gear transmission structure, and belt transmission structure.

[0068] The litter box may also include a control board electrically connected to the drive unit 5. The control board can precisely control the start, stop and rotation angle of the ball chamber assembly 2 through the drive unit 5.

[0069] It should be noted that the control board can be built using electronic components such as timers, comparators, registers, and digital logic circuits, or it can be implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0070] In some embodiments, such as Figure 1 and Figure 9 As shown, the transmission assembly 6 includes a driving gear 61 and a driven gear 62 that mesh with each other. The driving gear 61 is mounted on the base 1 and is connected to the output shaft of the drive member 5. The driven gear 62 is mounted on the ball chamber assembly 2, so that the drive member 5 drives the ball chamber assembly 2 to move through the driving gear 61 and the driven gear 62.

[0071] In this way, the drive component 5 can stably drive the ball compartment assembly 2 to move through the drive gear 61 and the driven gear 62, thus ensuring the motion stability of the ball compartment assembly 2.

[0072] The aforementioned drive component 5 may also include a reducer 7 connected to the drive motor to reduce the output speed of the drive motor.

[0073] The aforementioned driving gear 61 and driven gear 62 can mesh directly or through other gears. This application does not make specific limitations on this. As long as the driving gear 61 can drive the ball chamber assembly 2 to move through the driven gear 62.

[0074] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
