[0034] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0035] refer to Figure 1 and Figure 2 As shown, an embodiment of this application provides a roller structure 100, which includes a first roller member 110, a second roller member 120, and a base 130.
[0036] Specifically, in combination Figure 2 and Figure 3 As shown, the second roller 120 is detachably connected to the first roller 110. The base 130 is connected to the second roller 120 and the first roller 110 respectively, and the three together define a receiving compartment 140. The first roller 110 and the second roller 120 are connected and installed on the base 130. The base 130, the second roller 120 and the first roller 110 together define the receiving compartment 140 for cats to use for toileting.
[0037] In this application, the base 130 is provided with an extension 131, which is movably engaged with the second roller 120 and the first roller 110 respectively. The extension 131 covers the edge positions of the second roller 120 and the first roller 110. Accordingly, the extension 131 of the base 130 facilitates the support and engagement of the second roller 120 and the first roller 110, resulting in a more secure connection. The extension 131 of the base 130 covers the edge positions of the second roller 120 and the first roller 110, preventing the liquid in the containment chamber 140 from leaking through the connection gaps, thus improving the sealing performance of the roller structure 100. The first roller 110 or the second roller 120 can be disassembled from the base 130 to facilitate personnel to inspect and maintain the relevant components of the roller structure 100.
[0038] In addition, the roller structure 100 also includes a roller component 150. The receiving chamber 140 has an opening 141. The roller component 150 is installed at the opening 141 and is connected to the first roller component 110, the second roller component 120 and the base 130 respectively, so that the roller structure 100 can rotate relative to each other through the roller component 150.
[0039] Understandably, the roller structure 100 separates pet excrement and cat litter by rotating, which can reduce the psychological stress on cats during use, maintain the hygiene of the litter box, and reduce litter waste compared to manual cleaning, thus making it easier to clean up pet excrement and effectively reducing the frequency and difficulty of cleaning the litter box for users.
[0040] In one embodiment, alternatively, referencing Figure 3 and Figure 7As shown, the extension 131 extends from one side of the base 130 and surrounds the circumferential side of the base 130. The extension 131 of the base 130 is used to assemble and install the first roller component 110 and the second roller component 120. The extension 131 can cover the connection position between the base 130 and the first roller component 110 and the second roller component 120 to prevent liquid leakage at the gaps and improve the sealing performance of the roller structure 100.
[0041] Optionally, combined Figure 3 and Figure 5 As shown, the extension 131 is provided with a first limiting groove 1311, and both the first roller component 110 and the second roller component 120 are provided with a first limiting part 111. The first limiting part 111 is movably engaged with the first limiting groove 1311, so that the first limiting part 111 of the first roller component 110 and the first limiting part 111 of the second roller component 120 are respectively engaged in the first limiting groove 1311, thereby realizing the assembly and installation of the first roller component 110, the second roller component 120 and the base 130. Of course, the first limiting part 111 can be separated from the first limiting groove 1311, so as to facilitate the disassembly of the first roller component 110 and the second roller component 120 for inspection and maintenance of the roller structure 100, which has better flexibility.
[0042] Optionally, refer to Figure 7 As shown, the first roller component 110 and the second roller component 120 are symmetrically arranged to facilitate the replacement of the first roller component 110 or the second roller component 120. It has a foolproof design, simplifies the operation steps, makes the assembly and installation of the first roller component 110 and the second roller component 120 simple, and makes the overall roller structure 100 aesthetically pleasing.
[0043] In summary, the first roller component 110 and the second roller component 120 of the roller structure 100 are connected and installed on the base 130. The base 130, the second roller component 120, and the first roller component 110 together define a receiving compartment 140 for cats to use for toileting. The extension 131 of the base 130 is used to support and engage the second roller component 120 and the first roller component 110, resulting in a relatively firm connection. The extension 131 of the base 130 covers the edges of the second roller component 120 and the first roller component 110, preventing liquid in the receiving compartment 140 from leaking through the connection gaps, thus improving the sealing performance of the roller structure 100. The first roller component 110 or the second roller component 120 can be disassembled from the base 130 to facilitate personnel to inspect and maintain the relevant components of the roller structure 100, providing a better user experience.
[0044] refer to Figures 1 to 3As shown, an embodiment of this application provides another roller structure 100, which includes a first roller member 110, a second roller member 120, and a base 130.
[0045] Specifically, in combination Figure 2 and Figure 3 As shown, the second roller 120 is detachably connected to the first roller 110. The base 130 is connected to the second roller 120 and the first roller 110 respectively, and the three together define a receiving chamber 140. The base 130 is provided with an extension 131, which is movably engaged with the second roller 120 and the first roller 110 respectively, and the extension 131 covers the edge positions of the second roller 120 and the first roller 110. Correspondingly, the first roller 110 and the second roller 120 are connected and mounted on the base 130, and the base 130, the second roller 120, and the first roller 110 define a receiving chamber 140. The receiving compartment 140 is for cats to use in the toilet. The extension 131 of the base 130 is used to support and engage the second roller 120 and the first roller 110, making the connection relatively firm. The extension 131 of the base 130 covers the edges of the second roller 120 and the first roller 110 to prevent liquid from the receiving compartment 140 from leaking through the connection gaps, thus improving the sealing of the roller structure 100. The first roller 110 or the second roller 120 can be disassembled from the base 130 to facilitate personnel to inspect and maintain the relevant parts of the roller structure 100.
[0046] In one embodiment, alternatively, referencing Figure 3 and Figure 7 As shown, an extension portion 131 extends from one side of the base 130, surrounding the circumferential side of the base 130. The extension portion 131 is used to assemble and install the first roller member 110 and the second roller member 120, and can cover the connection position between the base 130 and the first roller member 110 and the second roller member 120 to prevent liquid leakage at gaps and improve the sealing performance of the roller structure 100. For example, the extension portion 131 is an annular structure, which can wrap around the first roller member 110 and the second roller member 120.
[0047] Optionally, combined Figure 3 and Figure 5As shown, the extension 131 is provided with a first limiting groove 1311, and the first roller component 110 and the second roller component 120 are both provided with a first limiting part 111. The first limiting part 111 is movably engaged with the first limiting groove 1311, so that the first limiting part 111 of the first roller component 110 and the first limiting part 111 of the second roller component 120 are respectively engaged in the first limiting groove 1311, thereby realizing the assembly and installation of the first roller component 110, the second roller component 120 and the base 130. Of course, the first limiting part 111 can be separated from the first limiting groove 1311, so as to facilitate the disassembly of the first roller component 110 and the second roller component 120 for inspection and maintenance of the roller structure 100, which has better flexibility.
[0048] In one embodiment, alternatively, such as Figure 5 As shown, the roller structure 100 also includes a sealing element 160. The sealing element 160 abuts against the groove wall of the first limiting groove 1311 and the first limiting part 111. The sealing element 160 can prevent leakage from the gap between the groove wall of the first limiting groove 1311 and the first limiting part 111 of the extension 131, thus improving the overall sealing performance. Furthermore, the base 130 is provided with a protective layer, and the sealing element 160 has a ring-shaped structure. When the first roller component 110 and the second roller component 120 are respectively assembled with the base 130, the sealing element 160 can abut and position the edge of the protective layer, reducing slippage and displacement of the protective layer, resulting in better technical effects. For example, the protective layer is a three-proof fabric, which has waterproof, oil-proof, and stain-proof functions, keeping the area around the litter box dry and extending the service life of the litter box.
[0049] Optionally, refer to Figure 4 and Figure 5 As shown, the roller structure 100 also includes a second limiting member 123. The first roller member 110 is provided with a second limiting groove 112, and the second roller member 120 is provided with a third limiting groove 122. The second limiting groove 112 and the third limiting groove 122 are correspondingly arranged. The opposite ends of the second limiting member 123 are respectively inserted into the second limiting groove 112 and the third limiting groove 122, so that the second limiting member 123 can seal the connection position of the first roller member 110 and the second roller member 120, reducing the possibility of leakage at the connection position of the first roller member 110 and the second roller member 120, and improving the sealing performance of the roller structure 100. Further, there are two second limiting members 123, which are symmetrically arranged at opposite ends of the base 130. Exemplarily, the second limiting member 123 is an elastic rubber strip, which can be movably engaged with the groove wall of the first limiting groove 1311.
[0050] Optionally, such as Figure 4As shown, both the protrusions of the second limiting groove 112 and the third limiting groove 122 are provided with mounting holes 124. The first roller component 110 and the second roller component 120 are screwed together through the mounting holes 124. The protrusions are used to connect and fix the position of the second limiting component 123, reducing the possibility of the second limiting component 123 loosening and falling off. The first roller component 110 and the second roller component 120 are connected by bolts passing through the mounting holes 124 for fixing, making the first roller component 110 and the second roller component 120 detachably connected, so as to facilitate the assembly and disassembly of the first roller component 110 and the second roller component 120.
[0051] In one embodiment, alternatively, referencing Figure 3 and Figure 6 As shown, a plurality of connectors 113 are spaced apart on one side of the first roller component 110, and the first roller component 110 is detachably connected to the second roller component 120 through the connectors 113. The plurality of connectors 113 enable the first roller component 110 and the second roller component 120 to be assembled by bolts. Of course, the plurality of connectors 113 can also form a snap-fit structure, and no specific limitation is made here.
[0052] Optionally, refer to Figure 7 As shown, the first roller component 110 and the second roller component 120 are symmetrically arranged to facilitate the replacement of the first roller component 110 or the second roller component 120. It has a foolproof design, simplifies the operation steps, makes the assembly and installation of the first roller component 110 and the second roller component 120 simple, and makes the overall roller structure 100 have better aesthetics.
[0053] In this application, such as Figure 3 As shown, the first roller 110 or the second roller 120 is provided with a pet opening 121. The opening 141 of the pet opening 121 is slightly larger than the size of the pet. The edge of the pet opening 121 is blunted to prevent damage to the pet, so that the pet can freely enter and exit through the pet opening 121.
[0054] In one embodiment, alternatively, referencing Figure 3 and Figure 7 As shown, the first roller component 110 is provided with a sand filter component 114 and a guide component 115. The sand filter component 114 and the guide component 115 are connected to form a sand-separating chamber. Both the sand filter component 114 and the guide component 115 are located within the receiving chamber 140. The sand filter component 114 can separate cat litter and pet excrement clumps in the receiving chamber 140. The guide component 115 can transport pet excrement clumps through the opening 141 to the outside of the roller structure 100 for cleaning. Furthermore, the guide component 115 can isolate pet excrement clumps and cat litter, achieving the effect of separating the two. Exemplarily, the sand filter component 114 is a mesh structure.
[0055] An embodiment of this utility model also provides a cat litter box, including the roller structure 100 in any of the above embodiments. The cat litter box including the roller structure 100 has all the beneficial effects of the roller structure 100, which will not be described in detail here.
[0056] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0057] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
