Automatic clean cat litter basin

Technical Field

The utility model relates to the field of pet supplies, in particular to an automatic cleaning cat litter box.

Background

The top of the traditional cat litter box is an open shallow box-shaped device, cat litter is filled in the device, and the cat litter can be excreted after entering the cat litter box. This open litter box has several disadvantages: first, they have little ability to adsorb or control odors from animal excretions, and, as such, such litter boxes are often placed at remote locations in the home; secondly, this type of litter box requires the breeder to periodically remove animal waste, replace litter from time to time, and occasionally clean the litter box; third, because cats themselves are accustomed to digging, kicking, or otherwise spreading cat litter within the cat case, it is common for a significant amount of cat litter or fecal matter to be kicked out of the litter box; moreover, since the lower edge of the litter box cannot block the cat, the cat sometimes "staggers the litter box" and excretes on the outer side edge of the litter box, depending on the habits of the individual cat; in addition, the bottom of the cat litter can carry a large amount of litter out of the litter box.

All these disadvantages will result in frequent cleaning operations in the litter box and surrounding ground, which will take a lot of time for the breeder, and if pet faeces are not handled in time, the smell emitted will seriously affect the indoor air environment, which will cause a lot of inconvenience for the breeder's daily life. For these problems, some cat litter boxes on the market have been able to address or circumvent some of these problems: for example, some litter boxes include a higher side wall and top and have an opening at one or either end to allow cats to enter and exit the box; in addition, certain litter boxes contain deodorizing materials to help mask odors from animal excretions; new litter technology has also developed "clustered" litter that clusters around liquid excretions so that breeders can more easily clean it out. While the litter box and the novel litter described above address some of the problems discussed above, they fail to address all of the problems.

CN111837971B discloses a cat excrement cleaning device and method. The cat excrement cleaning device comprises a containing rotating piece and a sand screening assembly, wherein the containing rotating piece is used for containing cat sand; the sand screening component is arranged in the accommodating rotating piece and comprises a first sand screening piece and a second sand screening piece, and the first sand screening piece can be overlapped with the second sand screening piece to form a sand loading groove or be closed to form a sand screening cavity, so that cat excrement is screened out. However, there is still room for improvement, even though the above-described device known from CN111837971B enables an automatic cleaning of cat faeces, which is not isolated from the surrounding environment, and thus unpleasant odours may still be emitted into the surrounding environment. Particularly, when a cat goes in and out of the cat litter box, the cat litter with peculiar smell is easy to carry out of the cat litter box.
