[0048] Embodiment 2

[0049] Reference Figures 1 to 3 As shown, an embodiment of the present application provides another litter box 100, which includes a housing 110, a litter box 120, and a sand replenishing device 130.

[0050] Specifically, with reference to Figure 2 and Figure 4 shown, the housing 110 is provided with a first installation groove 111 and a second installation groove 112; the litter box 120 is disposed in the first installation groove 111, and at least a part of the litter box 120 is exposed outside the housing 110. The litter box 120 is installed in the first installation groove 111 of the housing 110. The litter box 120 is exposed outside the housing 110 to facilitate the cat's use of the litter box 120. Cat litter can be provided in the litter box 120 to facilitate the pet cat's excretion in the litter box 120.

[0051] In this embodiment, the sand replenishing device 130 is disposed in the second installation groove 112, at least a part of the sand replenishing device 130 is exposed outside the housing 110. The sand replenishing device 130 is provided with a sand blocking member 131 and a sand outlet 132. The sand blocking member 131 isolates the sand outlet 132 of the sand replenishing device 130 from the cat litter cartridge 120, or the sand outlet 132 communicates with the cat litter cartridge 120. The sand replenishing device 130 is installed in the second installation groove 112 of the housing 110, and the sand replenishing device 130 is exposed outside the housing 110 to facilitate replenishing cat litter to the sand replenishing device 130. The sand outlet 132 of the sand replenishing device 130 is isolated from the cat litter cartridge 120 by the sand blocking member 131. When it is necessary to add cat litter into the cat litter cartridge 120, the sand blocking member 131 is opened to connect the sand outlet 132 of the sand replenishing device 130 with the cat litter cartridge 120. Cat litter can be replenished into the cat litter cartridge 120 through the sand outlet 132 of the sand replenishing device 130. When the sand blocking member 131 is opened as needed, the function of replenishing cat litter to the cat litter cartridge 120 is realized, improving the cleanliness and usability of the cat litter box 100.

[0052] Referring to Figure 3 As shown, the cat litter box 100 has a first direction. Exemplarily, the first direction is taken as the length direction of the cat litter box 100. It can be understood that the above definition is only for facilitating the understanding of the relative position relationship of each part in the cat litter box 100, and should not be construed as a limitation to the present application.

[0053] In one embodiment, optionally, referring to Figure 4 and Figure 5 As shown, the sand replenishing device 130 further includes a sand storage bin 133, a feeding member 134 and a driving assembly 135. The sand storage bin 133 communicates with the cat litter cartridge 120 through the feeding member 134. The driving assembly 135 is connected to the feeding member 134. The sand storage bin 133 is used for storing cat litter. When the driving assembly 135 is started, the cat litter in the sand storage bin 133 can enter the cat litter cartridge 120 through the feeding member 134, achieving the purpose of automatically adding cat litter to the cat litter cartridge 120. Exemplarily, the sand storage bin 133 is provided with a sand inlet 138. When the remaining amount of cat litter in the sand storage bin 133 is insufficient, cat litter can be added into the sand storage bin 133 through the sand inlet 138.

[0054] In addition, the driving assembly 135 can be controlled by a controller to turn on or off the driving assembly 135. When it is detected that the amount of cat litter in the cat litter cartridge 120 is lower than the standard value, the controller controls the driving assembly 135 to start and replenish cat litter into the cat litter cartridge 120, so that the amount of cat litter in the cat litter cartridge 120 is greater than or equal to the standard value. The controller can be an integrated circuit chip or a general-purpose processor. The controller further includes a memory for storing the above program instructions executable by the controller.

[0055] Optionally, in combination withFigure 8 and Figure 9 As shown, the sand blocking member 131 is provided with an elastic portion 1311. When the driving assembly 135 drives the material conveying member 134 to discharge sand, the elastic portion 1311 can be opened, or when the driving assembly 135 stops, the elastic portion 1311 can be closed. At this time, the closing of the elastic portion 1311 means blocking the passage of the cat litter. When the driving assembly 135 starts, it has a certain squeezing effect on the cat litter, causing the cat litter to squeeze the elastic portion 1311 of the sand blocking member 131, and the elastic portion 1311 can be opened to facilitate the cat litter to enter the cat litter cylinder 120. When the driving assembly 135 stops, the squeezing effect of the driving assembly 135 on the elastic portion 1311 of the sand blocking member 131 disappears, and the elastic portion 1311 of the sand blocking member 131 can automatically close to block the cat litter. At this time, the elastic portion 1311 of the sand blocking member 131 isolates the sand storage bin 133 and the cat litter cylinder 120.

[0056] Further, as Figure 9 shown, the sand blocking member 131 further includes a fixing portion 1312. The fixing portion 1312 is provided with an installation opening. The elastic portion 1311 is connected to the fixing portion 1312, and the elastic portion 1311 can be installed at the position of the installation opening. Among them, the elastic portion 1311 and the fixing portion 1312 can be integrally formed or separately arranged. The elastic portion 1311 needs to have certain elastic properties and recovery properties, but the material and properties of the fixing portion 1312 are not limited, and the fixing portion 1312 may not have elasticity. Exemplarily, the material of the elastic portion 1311 is one of rubber, neoprene, ethylene propylene rubber, and silicone rubber. The elastic portion 1311 can be a curtain-like structure or a comb-like structure. For example, the comb-like elastic portion 1311 has a plurality of parallel ridges (comb teeth) and grooves, which facilitates the opening and closing of the elastic portion 1311 to facilitate the passage of the cat litter or block the cat litter.

[0057] Optionally, referring to Figure 5 and Figure 6 shown, the material conveying member 134 includes a material conveying bin 1341, a transmission member 1342, and a material guiding member 1343. The material guiding member 1343 is arranged in the material conveying bin 1341, and the material guiding member 1343 is connected to the transmission member 1342, and the transmission member 1342 is connected to the driving assembly 135. That is, the cat litter enters the material conveying bin 1341 through the sand storage bin 133. The driving assembly 135 drives the material guiding member 1343 to move through the transmission member 1342, and the material guiding member 1343 drives the cat litter to move to achieve the purpose of squeezing the cat litter. Exemplarily, the transmission member is a transmission gear, and the driving gear of the driving assembly 135 meshes with the transmission gear.

[0058] Further, as Figure 6As shown, the material guiding member 1343 includes a material guiding plate 1343a and a transmission rod 1343b. The spiral-structured material guiding plate 1343a is disposed around the transmission rod 1343b to form a material guiding channel. One end of the transmission rod 1343b is connected to the transmission member 1342, so that the feed port of the material guiding channel communicates with the sand storage bin 133. A sand blocking member 131 is provided at the discharge port of the material guiding channel. In other words, the spiral-structured material guiding plate 1343a can push the cat litter to move. When the transmission member 1342 is connected to the transmission rod 1343b and the transmission member 1342 drives the transmission rod 1343b to rotate, the transmission rod 1343b drives the spiral-structured material guiding plate 1343a to rotate, causing the cat litter in the material guiding channel to move to a position gradually closer to the discharge port. The sand blocking member 131 can be opened under the extrusion action of the spiral-structured material guiding plate 1343a on the cat litter, allowing the cat litter to enter the cat litter cylinder 120 to supplement the cat litter in the cat litter cylinder 120.

[0059] In one embodiment, optionally, referring to Figure 7 and Figure 8 As shown, the sand replenishing device 130 is detachably connected to the second installation groove 112 and forms a snap structure with the second installation groove 112, that is, the sand replenishing device 130 can be disassembled and replaced. The sand replenishing device 130 and the second installation groove 112 are connected in a snap connection manner, improving the connection convenience. When there are component damages or problems with the sand replenishing device 130, it is convenient for maintenance and replacement. Exemplarily, the sand replenishing device 130 is a triangular structure.

[0060] Optionally, referring to Figure 10 As shown, the sand replenishing device 130 includes an installation cavity 137 and a snap component 136. The snap component 136 is disposed in the installation cavity 137. An installation card slot 1121 is provided in the second installation groove 112. The snap component 136 is movably clamped with the installation card slot 1121. The snap component 136 is clamped with the installation card slot 1121, or the snap component 136 is separated from the installation card slot 1121. The second installation groove 112 installs the sand replenishing device 130, and the snap component 136 is installed in the installation cavity 137 of the sand replenishing device 130. The structure is relatively compact and has better aesthetics.

[0061] Furthermore, as Figure 2 and Figure 8As shown, the number of the buckle components 136 is two. Along the first direction, the two buckle components 136 are located on the opposite sides of the sand filling device 130. The number of the installation slots 1121 is two. One installation slot 1121 corresponds to one buckle component 136. The installation slots 1121 can be two, and the two buckle components 136 are respectively clamped with the corresponding installation slots 1121. Of course, the number of the buckle components 136 can also be three, four, six, etc.

[0062] Optionally, referring to Figure 10 As shown, the buckle component 136 includes a buckle 1361, a connecting rod 1362 and an elastic member 1363. One end of the connecting rod 1362 is connected to the buckle 1361, and the end of the connecting rod 1362 away from the buckle 1361 is connected to the elastic member 1363. The elastic member 1363 can adopt a compression spring. Exemplarily, the buckle component 136 further includes a switch member 1364. By driving the connecting rod 1362 to move relatively through the switch member 1364, the connecting rod 1362 deforms the compression spring, and the connecting rod 1362 drives the buckle 1361 to contract, so that the sand filling device 130 is separated from the installation slot 1121. When the switch member 1364 is released, the compression spring resets to drive the connecting rod 1362 to move, and the buckle 1361 moves to the initial position, thereby realizing the purpose of the movable clamping of the buckle component 136.

[0063] In one embodiment, optionally, referring to Figure 2 and Figure 3 As shown, the cat litter cylinder 120 is a drum, and the drum is rotatably connected to the housing 110. The drum is provided with an opening 121, and the center line of the opening 121 is collinear with the axis of the drum. The sand outlet 132 extends into the drum through the opening 121. Since the opening 121 is located at the axis position of the drum, during the relative rotation of the drum, the position of the opening 121 remains unchanged and will not hinder or affect the sand feeding of the cat litter at the sand outlet 132, having better technical effects. Exemplarily, the drum is provided with a screen, so that the screen of the drum can collect and clean the cat litter used by pets by means of the rolling of the drum.

[0064] Optionally, as shown in Figure 2 As shown, the drum is further provided with a plurality of pet entrances for pets to enter and exit the drum, facilitating pets to excrete and use. The pet entrances are located on the circumference of the drum, and the number of the pet entrances can be one or more, facilitating the entry and exit of pets.

[0065] In all the examples shown and described here, any specific value should be construed as merely exemplary, not as a limitation. Therefore, other examples of the exemplary embodiments can have different values.

[0066] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
