[0031] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0032] Please also read Figures 1 to 6, the cat litter box provided in the embodiment of the present application is now described.

[0033] refer to Figures 1 to 4 The cat litter box of the present application includes a base 100 and a litter bin 200. The litter bin 200 is rotatably disposed on the base 100, and a bin opening 220 for a pet cat to enter and exit is disposed on the litter bin 200.

[0034] Among them, reference Figure 1 and Figure 2 A driving structure 140 is provided on the base 100, and a driven structure 210 is correspondingly provided on the sand bin 200. The driving structure 140 may be a motor and a gear, and the driven structure 210 may be a gear ring provided on the end surface of the sand bin 200 for meshing with the gear. At the same time, a guide arc surface 110 is formed on the base 100. The guide arc surface 110 is used to guide the rotation of the sand bin 200 after the sand bin 200 is rotatably provided on the base 100.

[0035] At the same time, a removable feces collecting box 130 is provided in the base 100. The feces collecting box 130 is used to collect cat litter balls with feces attached. The feces collecting box 130 can be pulled out to leave the base 100 so that the garbage bag can be installed and replaced. Correspondingly, a feces outlet 230 is provided on the circumferential surface of the sand bin 200, and a feces collecting port 120 is provided on the guide arc surface 110 of the base 100. The feces collecting port 120 is always connected to the feces collecting box 130, and the feces outlet 230 can only be connected to the feces collecting port 120 after the sand bin 200 rotates a certain angle.

[0036] For further reference, Figure 3 and Figure 4 At least one side of the feces collecting opening 120 in the direction perpendicular to the circumferential tangent of the guide arc surface 110 is a curved edge 121, and the curved edge 121 is in any of a sawtooth shape, a wave shape, and a continuous groove shape. At the same time, the curved edge 121 has a plurality of notches in the direction perpendicular to the circumferential tangent of the guide arc surface 110, and each notch has a depth in the circumferential tangent direction of the guide arc surface 110 and a width in the direction perpendicular to the circumferential tangent of the guide arc surface 110, and the depth of the notch is greater than its width.

[0037] By making at least one side of the feces collecting opening 120 perpendicular to the tangent direction of the circumference of the guiding arc surface 110 a curved edge 121, the feces collecting opening 120 has at least two opening sizes, namely, the first drop area corresponding to each notch, and the other areas in the feces collecting opening 120 except each notch, namely, the second drop area. When the particles of the cat litter group are small, the cat litter group can fall into the feces collecting box 130 from the first drop area or the second drop area; and when the particles of the cat litter group are large (that is, the diameter of the cat litter group particles is larger than the width of the notch), the cat litter group can be first blocked by the first drop area, and then fall into the feces collecting box 130 from the second drop area under the guidance of the guiding arc surface 110, thereby avoiding the problem of scattering caused by the cat litter group with large particles falling directly into the feces collecting box 130, so that the feces in the feces collecting box 130 are exposed and emit odor.

[0038] In some embodiments, the toilet opening 120 is integrally formed on the base 100 .

[0039] refer to Figure 3 and Figure 4 In some other embodiments, the feces collecting opening 120 is detachably provided on the base 100. Specifically, an opening is provided on the guide arc surface 110, and a baffle 150 is detachably provided in the opening, and the feces collecting opening 120 is provided on the baffle 150. In this way, after the baffle 150 has been used for a period of time, the baffle 150 can be conveniently disassembled for cleaning; at the same time, the molding process of the base 100 can also be facilitated.

[0040] Specifically, the baffle 150 and the base 100 may be detachably connected by a snap-fit ​​connection to facilitate disassembly.

[0041] refer to Figure 4 Furthermore, in some embodiments, a barrier strip 160 is provided around the feces collecting opening 120 on the guide arc surface 110. When the sand bin 200 is mounted on the guide arc surface 110, the barrier strip 160 abuts against the outer wall of the sand bin 200. In this way, on the one hand, the provision of the barrier strip 160 can provide a certain damping for the rotation of the sand bin 200, so as to slow down the rotation of the sand bin 200 and make its rotation smoother; on the other hand, when the sand bin 200 rotates to a position where the feces outlet 230 thereon is staggered from the feces collecting opening 120 on the base 100, the barrier strip 160 can seal the gap between the sand bin 200 and the guide arc surface 110, so as to reduce the leakage of feces odor in the feces collecting box 130.

[0042] refer to Figure 5 On the basis of any of the above embodiments, the feces collecting box 130 may be arranged in the following manners: That is, a fence 131 is formed on the feces collecting box 130, and the fence 131 is a quadrilateral as an example.

[0043] The enclosure 131 is enclosed inside to form a feces collection area. When in use, the drawstring bag is sleeved on the enclosure 131 so that feces falling from the feces collection port 120 can directly fall into the drawstring bag. Further, elastic plates 1311 are provided on the three adjacent sides of the enclosure 131, and a tightening structure 132 is provided at the front end of the enclosure 131. In this way, when the drawstring bag is sleeved on the enclosure 131, the tightening rope at the opening edge of the drawstring bag can be stretched open by each elastic plate 1311, and at the same time, the tightening end of the tightening rope is sleeved in the tightening structure 132 to be fixed. In this way, when it is necessary to remove the drawstring bag containing feces, the tightening rope can be tightened at the tightening structure 132. After the tightening rope is pulled, the opening of the drawstring bag becomes smaller, and the elastic plate 1311 is pulled to elastically deform relative to the enclosure 131 structure so that it can be smoothly detached from the enclosure 131.

[0044] Furthermore, the elastic plate 1311 arranged opposite to the tightening structure 132 is rotatably arranged on the enclosure 131 structure, and an elastic member is arranged between the enclosure 131 structure and the elastic plate 1311. In this way, only one elastic plate 1311 is movably arranged, so that when the tightening rope is pulled, the elastic plate 1311 opposite to the tightening structure 132 rotates relative to the enclosure 131 structure to release the edge of the drawstring bag sleeved thereon, while the other two elastic plates 1311 maintain the supporting effect on the edge of the drawstring bag, and continue to pull the tightening rope, and the parts of the drawstring bag sleeved on the other two edges of the enclosure 131 structure are successively pulled out until the opening size of the drawstring bag is gradually reduced and completely closed, at which time, the drawstring bag can be taken out by pulling the tightening rope from the tightening structure 132.

[0045] Furthermore, a decorative plate is provided on the front side of the enclosure 131 structure, and the tightening structure 132 is a groove formed on the decorative plate with multiple bends and one end connected to the side of the decorative plate. In some embodiments, the groove is in a bent "G" shape. By bending the groove, the tightening rope can be effectively prevented from detaching from the groove, so as to facilitate the tightening operation of the drawstring bag.

[0046] refer to Figure 3 and Figure 4 and Figure 6 Based on any of the above embodiments, the driving structure 140 may have the following configuration.

[0047] In some embodiments, the driving structure 140 is disposed on both sides of the base 100, and the driven structure 210 is correspondingly disposed on both sides of the sand bin 200; the bin opening 220 and the discharge opening 230 are both disposed on the circumference of the sand bin 200. Specifically, supports 170 are disposed on both sides of the base 100, one of which is provided with a gear, and the other is provided with a guide roller; correspondingly, a gear ring and a guide convex ring are respectively disposed at both ends of the sand bin 200, the gear ring is meshed and connected with the gear, and the guide convex ring is in rolling contact with the guide roller.

[0048] In other embodiments, the driving structure 140 is disposed on one side of the base 100, and the driven structure 210 is correspondingly disposed on one side end surface of the sand bin 200; the bin opening 220 is disposed on the other end surface of the sand bin 200. Similarly, a support 170 is disposed on one side of the base 100, and a gear is disposed on the support 170. Correspondingly, a gear ring is disposed on one end of the sand bin 200, and the gear ring is meshed with the gear.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
