Description

Technical Field

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

[0002] With social development and the continuous progress of science and technology, more and more people enjoy keeping pets at home, among which cats are a common choice. Because cats have a habit of burying their excrement, special litter boxes are now commonly used to facilitate the placement of cat waste in designated areas.

[0003] Existing litter boxes generally adopt the following structure: a bottom shell, an upper shell that is detachably attached to the top of the bottom shell, a cavity for holding cat litter inside the bottom shell, and an entrance / exit for the cat to enter and exit on the upper surface of the upper shell. A door panel that can be rotatably installed at the entrance / exit can be opened or closed. The cat can only enter and exit the litter box through this entrance / exit. If the rotating shaft of the door panel gets stuck, the cat cannot enter or exit the litter box. In addition, the cat can only enter and exit the litter box through a fixed entrance / exit, and the route to enter and exit the litter box is singular, which is not convenient for the cat to play and has low playability.

[0004] In addition, existing cat litter boxes are usually made up of two parts: a bottom shell and a top shell. In order to make the cat litter box have a high space, the bottom shell and the top shell are relatively high, which makes the cat litter box packaging volume large and inconvenient for transportation. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cat litter box with two inlets and outlets for entering and exiting the litter box, facilitating cat entry and exit, while also reducing the packaging volume for easier transportation.

[0006] A cat litter box according to an embodiment of the present invention includes a litter box shell, which comprises a lower shell, a middle shell, and an upper shell. The middle shell is detachably installed on the upper part of the lower shell, and the upper shell is detachably installed on the upper part of the middle shell. The middle shell is an annular component with a hollow interior. The interior of the lower shell is connected to the interior of the upper shell through the middle shell. The upper surface of the upper shell has a first inlet and outlet, and the upper surface of the upper shell is rotatably mounted with a first door capable of opening or closing the first inlet and outlet. The middle shell and the upper shell are joined together to form a top shell. The side wall of the top shell has a second inlet and outlet, and the top shell is rotatably mounted with a second door capable of opening or closing the second inlet and outlet.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] Reference Figures 1 to 12 and mainly refer to Figure 3 , Figure 4 , Figure 5 and Figure 9According to certain embodiments of the present invention, a cat litter box is sometimes simply referred to as a "cat litter box". A cat litter box includes a litter box shell 100, which comprises a lower shell 110, a middle shell 120, and an upper shell 130. The middle shell 120 is detachably mounted on the upper part of the lower shell 110, and the upper shell 130 is detachably mounted on the upper part of the middle shell 120. The middle shell 120 is a hollow annular component. The interior of the lower shell 110 is connected to the interior of the upper shell 130 through the middle shell 120. That is, the lower shell 110, the middle shell 120, and the upper shell 130 are detachably assembled from each other in a bottom-to-top direction to form the cat litter box shell 100. The upper surface of the upper housing 130 is provided with a first inlet and outlet 131, and a first door 132 capable of opening or closing the first inlet and outlet 131 is rotatably mounted on the upper surface of the upper housing 130; the middle housing 120 and the upper housing 130 are spliced ​​together to form a top housing 140, the side wall of the top housing 140 is provided with a second inlet and outlet 141, and the top housing 140 is rotatably mounted with a second door 142 capable of opening or closing the second inlet and outlet 141.

[0037] In this embodiment, the litter box shell 100 is configured as a detachable assembly of a lower shell 110, a middle shell 120, and an upper shell 130. Therefore, the height or thickness of the lower shell 110, middle shell 120, and upper shell 130 can be made smaller. When transporting the litter box, the litter box shell 100 can be disassembled into the lower shell 110, middle shell 120, and upper shell 130 for packaging, resulting in a smaller packaging volume and facilitating the transportation or storage of the litter box. Simultaneously, the upper shell 130 has a first inlet / outlet 131 on its upper surface, and the middle shell 120... The top shell 140, which is formed by splicing the top shell 130 and the upper shell 140, has a second inlet and outlet 141 on its side wall. Therefore, the cat can choose to enter and exit the litter box shell 100 from the first inlet and outlet 131 or the second inlet and outlet 141. This solves the technical problem that the door of the traditional litter box with a single inlet and outlet can block the cat from entering and exiting the litter box. Moreover, the litter box in this embodiment has a first inlet and outlet 131 and a second inlet and outlet 141 for the cat to choose to enter and exit the litter box shell 100, which increases the cat's route to enter and exit the litter box shell 100, making the cat box more playful and better in line with the cat's playful nature.

[0038] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 5 and Figure 9To simplify the structure of the litter box, in some embodiments of this invention, the front side wall of the top shell 140 has a mounting hole 145, and a mounting base 143 is detachably mounted at the mounting hole 145. A second inlet / outlet 141 is located in the middle of the mounting base 143, and a second door 142 is rotatably mounted on the mounting base 143. The mounting base 143 is provided with a second limiting structure that restricts the rotation of the second door 142 relative to the mounting base 143. By adopting the above structure, the upper shell 130, middle shell 120, mounting base 143, and second door 142 can be manufactured separately, and then assembled together, facilitating the production of the litter box.

[0039] Reference Figure 3 , Figure 4 , Figure 5 , Figure 9 , Figure 11 and Figure 12 Specifically, the mounting base 143 is detachably mounted on the mounting hole 145, and the second door 142 is mounted on the side of the mounting base 143 facing the inside of the litter box housing 100. At this time, the second door 142 is located inside the litter box housing 100, and the upper part of the second door 142 is rotatably connected to the upper part of the mounting base 143. The second limiting structure includes a second knob 144 rotatably mounted on the lower part of the mounting base 143, and a limit stop 1441 is provided on the upper part of the second knob 144. The lower part of the second door 142 has a clearance notch 1421 that matches the limiting stop 1441. When the second knob 144 drives the limiting stop 1441 to rotate relative to the mounting base 143 and the limiting stop 1441 is fitted into the clearance notch 1421, the limiting stop 1441 and the clearance notch 1421 do not interfere with each other. The second door 142 can rotate relative to the mounting base 143 to the inside or outside of the litter box housing 100 and open the second inlet / outlet 141; Figure 12As shown, when the second knob 144 drives the limiting stop 1441 to rotate relative to the mounting base 143 and causes the limiting stop 1441 to be misaligned with the clearance notch 1421, the limiting stop 1441 is no longer fitted into the clearance notch 1421. At this time, the limiting stop 1441 can abut against the lower part of the outer surface of the second door 142 and restrict the second door 142 from rotating to the outside of the litter box housing 100 to open the second inlet and outlet 141. At this time, the cat can enter the litter box housing 100 from the second inlet and outlet 141. After that, the cat can only leave the litter box housing 100 from the first inlet and outlet 131, thereby realizing the control of the cat's route in and out of the litter box housing 100. By adopting the above structure, the user can turn the second knob 144 to drive the limiting stop 1441 to rotate relative to the mounting base 143 and make the limiting stop 1441 misalign or align with the clearance notch 1421, thereby enabling the second limiting structure to restrict the second door 142 from rotating relative to the mounting base 143 toward the litter box shell 100 or to release the restriction of the second limiting structure on the second door 142, making the operation simpler and more convenient.

[0040] It is understood that in the above embodiments, the second limiting structure adopts a structure in which the second knob 144, the limiting stop 1441, and the clearance notch 1421 cooperate. In other embodiments of this utility model, the second limiting structure may also adopt other structures, such as the second limiting structure including a second pin and a second positioning hole. The second positioning hole is opened on the side wall of the mounting base 143, and the second pin is movably installed at the position corresponding to the second door body 142 and the second positioning hole. When the user drives the second pin to insert into the second positioning hole, the second pin and the second positioning hole cooperate with each other and lock the second door body 142 and the mounting base 143 together. At this time, the second limiting structure can restrict the rotation of the second door body 142 relative to the mounting base 143. When the user drives the second pin to come out from inside the second positioning hole, the locking between the second door body 142 and the mounting base 143 is released. At this time, the second door body 142 can rotate freely relative to the mounting base 143.

[0041] In some embodiments of this utility model, the front end side wall of the upper housing 130 is provided with an upper notch 1301, and the front end side wall of the middle housing 120 is provided with a lower notch 1201. When the upper housing 130 is detachably installed on the upper part of the middle housing 120, the upper notch 1301 and the lower notch 1201 are spliced ​​together to form a mounting hole 145. By adopting the above structure, the structure of the upper housing 130 and the middle housing 120 is simpler and easier to manufacture.

[0042] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6In order to better install the first door 132 onto the upper housing 130, in some embodiments of this utility model, one end of the first door 132 is rotatably connected to the upper housing 130, and a first limiting structure is provided between the other end of the first door 132 and the upper housing 130. The first limiting structure can restrict the first door 132 from rotating upward relative to the upper housing 130 to open the first inlet / outlet 131. Specifically, the first limiting structure includes a first knob 133 rotatably mounted on the upper surface of the first door 132. One end of the first knob 133 passes through the first door 132 and is connected to a first latching member 134. The first knob 133 can drive the first latching member 134 to rotate relative to the first door 132 and cause the first latching member 134 to latch onto the inner wall of the upper housing 130; or the first knob 133 can drive the first latching member 134 to rotate relative to the first door 132 and release the latching member 134 from the inner wall of the upper housing 130. When the user drives the first locking member 134 to rotate via the first knob 133, causing the first locking member 134 to engage with the inner wall of the upper housing 130, the first door 132 can only rotate inwards towards the upper housing 130, opening the first inlet / outlet 131. At this time, the cat can enter the litter box housing 100 through the first inlet / outlet 131, and then the cat can only leave the litter box housing 100 through the second inlet / outlet 141, thus controlling the cat's route into the litter box housing 100. By adopting the above structure, the user can more conveniently control whether the first door 132 rotates towards the upper housing 130 through the first limiting structure.

[0043] It should be noted that in the above embodiments, the first limiting structure adopts a structure composed of a first knob 133 and a first snap-fit ​​member 134. However, in other embodiments of this utility model, the first limiting structure can also adopt other structures, such as the first limiting structure including a first pin and a first positioning hole. The first positioning hole is fixedly opened on the inner side wall of the first inlet / outlet 131, and the first pin is movably installed at the position corresponding to the first door body 132 and the first positioning hole. When the user drives the first pin to be inserted into the first positioning hole, the first pin and the first positioning hole cooperate to lock the first door body 132 and the upper housing 130 together, thereby restricting the rotation of the first door body 132 relative to the upper housing 130. When the user drives the first pin to be dislodged from the inside of the first positioning hole, the locking between the first door body 132 and the upper housing 130 is released, and the first door body 132 can rotate freely relative to the upper housing 130. The operation is simple and convenient.

[0044] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8To simplify the assembly between the middle housing 120 and the upper housing 130, in some embodiments of this invention, one or more first snap-fit ​​components are provided between the middle housing 120 and the upper housing 130.

When the upper housing 130 is installed on the upper part of the middle housing 120, the first hook 210 can engage with the first locking block 220. By adopting the above structure, the detachable connection between the middle housing 120 and the upper housing 130 can be simplified, facilitating assembly.

[0045] In some embodiments of this utility model, the first locking block 220 is fixedly disposed on the upper part of the middle housing 120, the first locking hook 210 is rotatably installed on the lower part of the inner side wall of the upper housing 130, and the outer surface of the upper housing 130 is provided with a third knob 211 connected to the first locking hook 210. When the upper housing 130 is installed on the upper part of the middle housing 120, the third knob 211 can drive the first locking hook 210 to rotate relative to the upper housing 130 and make the first locking hook 210 engage with the first locking block 220, or the third knob 211 can drive the first locking hook 210 to rotate relative to the upper housing 130 and release the engagement between the first locking hook 210 and the first locking block 220. By adopting the above structure, the user can drive the first hook 210 to rotate and engage the first hook 210 with the first locking block 220 by using the third knob 211, or the user can drive the first hook 210 to rotate and disengage the first hook 210 from the first locking block 220 by using the third knob 211. The operation is simple and convenient, making it easy for the user to assemble and connect the middle housing 120 and the upper housing 130, or to disassemble and separate the middle housing 120 and the upper housing 130.

[0046] In order to make the connection between the middle shell 120 and the upper shell 130 more secure, in some embodiments of the present invention, two sets of first snap-fit ​​components are provided between the middle shell 120 and the upper shell 130. The two sets of first snap-fit ​​components are respectively provided on opposite sides of the upper shell 130. At this time, the upper shell 130 can be snapped with the middle shell 120 through the two sets of first snap-fit ​​components, thereby making the connection between the middle shell 120 and the upper shell 130 more secure and reliable.

[0047] It should be noted that in the above embodiments, the middle housing 120 and the upper housing 130 are detachably connected by the first snap-fit ​​assembly. In other embodiments of this utility model, the middle housing 120 and the upper housing 130 can also adopt other detachable connection structures, such as the middle housing 120 and the upper housing 130 being connected together by bolts. During installation, the user only needs to use bolts to lock the middle housing 120 and the upper housing 130 together. During disassembly, the user only needs to unscrew the bolts to separate the middle housing 120 and the upper housing 130. The operation is simple and convenient.

[0048] Reference Figure 1 , Figure 2 , Figure 6 , Figure 8 and Figure 10 In some embodiments of this utility model, one or more second snap-fit ​​components are provided between the lower housing 110 and the middle housing 120. Each second snap-fit ​​component includes a second hook 230 and a second snap-fit ​​block 240.
