Description

Technical Field

[0001] This utility model relates to the field of cat litter box technology, and more specifically, to cat litter boxes. Background Technology

[0002] Chinese patent CN116868899A discloses a smart litter box, which mainly consists of a base and a ball chamber that can rotate clockwise and counterclockwise on the base. Because the ball chamber is pieced together, after prolonged use, the cat's excrement and fine litter can seep out from the seams, affecting the hygiene of the area outside the ball chamber. Furthermore, litter on the cat's body or paws during use is also likely to splash into the gap between the base and the ball chamber, further increasing cleaning difficulty. Therefore, it is necessary to provide an improved litter box to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this utility model is to provide a cat litter box to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A litter box includes a base and a ball chamber detachably connected to the base and rotating in clockwise and counterclockwise directions. The base forms a hollow cavity that runs vertically through the interior, and a tray is provided at the upper opening of the hollow cavity to support it.

[0006] Furthermore, the tray is provided with a barrier around its four edges, and the tray is configured with a structure that is concave inward around its four sides.

[0007] Furthermore, a limiting groove is provided along the circumference of the upper opening of the hollow cavity, and a retaining edge is provided on the outer edge of the enclosure to match the limiting groove.

[0008] Furthermore, at least one notch is provided along the circumference of the upper opening of the hollow cavity, which communicates with the limiting groove.

[0009] Furthermore, the sphere is composed of two hemispherical spheres joined together, and a leak-proof strip is provided at the joint of the spheres to cover the joint.

[0010] Furthermore, the leak-proof strip is equipped with screws, and the joint of the ball chamber is provided with screw holes that are compatible with the screws.

[0011] Furthermore, the ball chamber has three spaces arranged in sequence along its circumference: a waste collection chamber, a litter collection chamber, and a litter placement area. The litter collection chamber is enclosed by a filter screen, a guide plate, and a partition separating the waste collection chamber and the litter collection chamber. The filter screen is close to the litter placement area, and the guide plate connects to the filter screen and extends to the waste inlet of the waste collection chamber. A baffle is provided at the entrance of the ball chamber relative to the guide plate.

[0012] Furthermore, the baffle is disposed at the end of the guide plate to form an L-shaped stop.

[0013] Furthermore, an installation cylinder is provided at the middle of the rear end of the ball compartment, a rear cover is provided on the base, and a connecting mechanism that cooperates with the installation cylinder is provided on the rear cover.

[0014] Furthermore, the mounting cylinder is provided with an annular groove, and the annular groove is provided with a plurality of insert posts;

[0015] The connecting mechanism includes a connecting seat aligned with the axis of the mounting cylinder, the connecting seat having a slot adapted to the inner and outer walls of the mounting cylinder, and a limiting post adapted to the insertion post being provided in the slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention improves the base structure by installing a tray in the hollow part of the base. The tray is used to collect and hold cat litter and excrement that seeps out of the ball chamber, preventing further leakage to the ground. When cat litter or excrement is found between the ball chamber and the base, the ball chamber can be separated from the base and the tray can be removed for quick cleaning.

[0018] Secondly, the spherical compartment of this utility model is composed of two hemispheres joined together. The seam is covered with a leak-proof strip at the joint, which can further reduce leakage of the spherical compartment and also prevent excrement from leaking into the shell of the spherical compartment, thus preventing contamination and damage to the components installed inside the shell.

[0019] Additionally, as the litter box rotates, the filter screen rotates accordingly, allowing cat litter to enter the litter collection chamber. At the same time, the baffle also rotates with the litter box. As the filter screen filters cat litter and litter clumps, the baffle can prevent some of the filtered cat litter from overflowing towards the litter box inlet, thus preventing cat litter from falling outside the litter box and improving the litter box's effectiveness.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-11A litter box includes a base 1 and a ball chamber 2 that is detachably connected to the base 1 and rotates in clockwise and counterclockwise directions. The base 1 forms a hollow cavity 3 that runs vertically through the interior and exterior. A tray 4 is provided at the upper opening of the hollow cavity 3 to support it.

[0035] When in use, install tray 4 onto base 1, then install and assemble two hemispherical compartments onto base 1 to form spherical compartment 2. Once installed, it can be used.

[0036] If the litter at the bottom of the ball chamber 2 cannot absorb or cover all the cat's excrement, such as when there is little litter in the ball chamber 2 or when it has not been cleaned for a long time, the excrement will leak out from the bottom seam of the ball chamber 2. The excrement will eventually fall onto the tray 4 for collection. In addition, the tray 4 can also catch the litter that leaks out of the ball chamber 2. Thus, the tray 4 can receive and collect the litter and excrement that seep out of the ball chamber 2, preventing further leakage to the ground and better protecting the hygiene of the environment outside the ball chamber 2.

[0037] When cat litter or excrement is found between the ball compartment 2 and the base 1, simply separate the ball compartment 2 from the base 1 and remove the tray 4 for quick cleaning. The cleaning is easy, time-saving, and convenient for users to perform daily operations.

[0038] In addition, when a cat defecates and liquid splashes onto the sides of the first shell 201 and the second shell 202, the side guards 5 can prevent the liquid from overflowing from the side seams and prevent liquid leakage.

[0039] The bottom protector 4 and side protector 5 prevent liquid from leaking into the base 1 or the side of the ball chamber 2, thus avoiding the problem of difficult cleaning. This greatly reduces the risk of bacterial growth and strong odor, improving the cleanliness and hygiene of the litter box. It also prevents liquid from dripping onto the floor from the base 1 and causing pollution in the home. Furthermore, it prevents liquid from overflowing into the smart litter box and damaging electrical components, providing excellent protection for the litter box and greatly improving its lifespan and hygiene.

[0040] After a period of time, when disassembling and cleaning the litter box, the first shell 201 and the second shell 202 can be removed and cleaned respectively, and the bottom protector 4 can be removed and cleaned. The operation is convenient and quick, the bottom protector 4 can be reused, reducing costs and making it highly practical.

[0041] In this embodiment, preferably, as shown in 6-8, the tray 4 is provided with a barrier 41 at its four edges, and the tray 4 is configured with a structure that is concave inward around its four sides.

[0042] With this design, the tray 4 has a concave structure on all sides, so the excrement falling into the tray 4 will gather towards the center of the tray 4; and the enclosure 41 can keep the liquid inside the tray 4, preventing the liquid from flowing out from the edges of the tray 4, thus improving the liquid collection effect.

[0043] In this embodiment, preferably, please refer to 6-8, a limiting groove 5 is provided along the circumference of the upper opening of the hollow cavity 3, and a retaining edge 42 adapted to the limiting groove 5 is provided on the outer edge of the enclosure 41.

[0044] With this design, when installing the tray 4, the tray 4 is placed above the limiting groove 5 of the base 1, and the retaining edge 42 on the perimeter of the tray 4 is placed inside the limiting groove 5. That is, the retaining groove 5 restricts the retaining edge 42, which can limit the installation of the tray 4 and prevent the tray 4 from moving on the base 1, thereby improving the stability of the tray 4.

[0045] For preferred options, please refer to [link / reference]. Figure 6-7 At least one notch 6 communicating with the limiting groove 5 is provided along the circumference of the upper opening of the hollow cavity 3.

[0046] With this design, when disassembling the tray 4, you can insert your fingers or tools into the slot 6 and then pry open the retaining edge 42 to remove the tray 4 and disengage it from the limiting slot 5, thus completing the disassembly of the tray 4. This is more convenient and less strenuous, and reduces damage to the retaining edge 42 and the tray 4.

[0047] In this embodiment, preferably, please refer to [reference needed]. Figure 3-7 The sphere 2 is composed of two hemispherical spheres joined together, and a leak-proof strip 7 is provided at the joint of the sphere 2 to cover the joint.

[0048] Specifically, the leak-proof strip 7 can be glued to the seam between the two hemispheres of the litter box 2. By sealing the seam with the leak-proof strip 7, it can prevent the cat from urinating and defecating into the seam, further reducing leakage of the litter box 2. It also prevents excrement from leaking into the shell of the litter box 2, contaminating and damaging the components inside the shell, and reducing the occurrence of bacterial growth and strong odor, thus improving the protective effect of the litter box.

[0049] In this embodiment, preferably, please refer to [reference needed]. Figure 3-4 The leak-proof strip 7 is equipped with screws 8, and the joint of the ball chamber 2 is provided with screw holes that are compatible with screws 8.

[0050] This design allows the leak-proof strip 7 to be installed at the joint of the ball chamber 2 by means of adhesive or other methods, and the screws 8 can be used to make it cooperate with the screw holes to further fix the leak-proof strip 7, which can greatly improve the stability of the leak-proof strip 7 and reduce the possibility of the leak-proof strip 7 falling off.

[0051] In this embodiment, preferably, please refer to [reference needed]. Figure 1 , Figure 3 , Figure 5 and Figure 9 The ball chamber 2 has three spaces arranged in a circumferential direction: a waste collection chamber 22, a litter collection chamber 21, and a litter placement area 23. The litter collection chamber 21 is formed by a filter screen 9, a guide plate 11, and a partition that separates the waste collection chamber 22 and the litter collection chamber 21. The filter screen 9 is close to the litter placement area 23. The guide plate 11 connects to the filter screen 9 and extends to the waste inlet of the waste collection chamber 22. A baffle 10 is provided at the entrance of the ball chamber 2 relative to the guide plate 11.

[0052] With this design, the filter 9 can separate cat litter clumps from cat litter. When the ball chamber 2 rotates, cat litter enters the litter collection chamber 21, while cat litter clumps are blocked on the filter 9 and eventually enter the waste collection chamber 22.

[0053] At this time, the guide plate 11 and the baffle 10 will also rotate together with the ball chamber 2. When the filter screen 9 is filtering cat litter and cat litter clumps, some cat litter will roll on the filter screen 9 and fall towards the guide plate 11. Eventually, it will overflow outwards along the guide plate 11 towards the inlet of the ball chamber 2. At this time, the baffle 10 at the inlet of the ball chamber 2 relative to the position of the guide plate 11 can block the overflow of cat litter, which can reduce the phenomenon of cat litter falling outside the cat litter box and is highly practical.

[0054] The baffle 10 can be installed on the inner wall of the ball chamber 2 at the entrance relative to the guide plate 11, or it can be installed at the end of the guide plate 11, depending on the specific requirements.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 1 , Figure 5 and Figure 9 The baffle 10 is located at the end of the guide plate 11, forming an L-shaped stop.

[0056] With this design, the baffle 10 is located at the end of the guide plate 11. That is, when the ball chamber 2 rotates, some of the cat litter that falls onto the guide plate 11 during the process of entering the litter collection chamber 21 is blocked by the baffle 10 when it is about to overflow the inlet of the ball chamber 2, which can prevent the cat litter from falling out of the inlet of the ball chamber 2 when the ball chamber 2 rotates.

[0057] In this embodiment, preferably, please refer to [reference needed]. Figure 9-11 An installation cylinder 12 is provided at the middle of the rear end of the ball chamber 2, and a rear cover 13 is provided on the base 1. A connecting mechanism 14 that cooperates with the installation cylinder 12 is provided on the rear cover 13.

[0058] Specifically, when installing the ball compartment 2, the mounting cylinder 12 of the ball compartment 2 is connected to the connecting mechanism 14 on the rear cover 13, which enables the ball compartment 2 to be quickly installed and disassembled, making it easy to operate.

[0059] The rear cover 13 is equipped with a drive device that drives the mounting cylinder 12 and the ball chamber 2 to rotate through the connecting mechanism 14, so that the ball chamber 2 achieves the effect of rotation.

[0060] In this embodiment, preferably, please refer to [reference needed]. Figure 9-11 The mounting cylinder 12 has an annular groove 15, and the annular groove 15 is provided with multiple insertion posts 16;

[0061] The connecting mechanism 14 includes a connecting seat 141 aligned with the axis of the mounting cylinder 12. The connecting seat 141 has a slot 142 adapted to the inner and outer walls of the mounting cylinder 12. The slot 142 has a limiting post 143 adapted to the insertion post 16.

[0062] Specifically, when installing the ball chamber 2, the mounting cylinder 12 of the ball chamber 2 is inserted into the slot 142 of the connecting seat 141, and the insert 16 is inserted into the limiting post 143. Finally, the limiting post 143 is located in the annular groove 15, thus completing the connection between the mounting cylinder 12 and the connecting seat 141. Subsequently, when the connecting seat 141 rotates, it will drive the mounting cylinder 12 and the ball chamber 2 to rotate.

[0063] For preferred options, please refer to [link / reference]. Figure 1 , Figure 3 and Figure 5 The upper end of the base 1 is provided with a roller 17 that contacts the outer wall of the ball chamber 2. With this design, when the ball chamber 2 rotates, it will rotate along the roller 17 of the base 1, which can improve the smoothness of the rotation of the ball chamber 2 and reduce friction; and the support of the bottom of the ball chamber 2 by the roller 17 can improve the stability of the ball chamber 2.
