Description

Technical Field

[0001] The utility model relates to the technical field of automatic cat litter boxes, in particular to a urine leakage prevention structure of an automatic cat litter box. Background Art

[0002] With the continuous improvement of material living standards, people's requirements for spiritual life are gradually increasing, and more and more people like to keep pet cats. Although many cat lovers like pet cats very much, cleaning the excrement produced by pet cats is a time-consuming and laborious task, so there are special fully automatic pet cat toilets. Among the existing automatic pet cat toilets, the drum-type automatic pet cat toilet based on the principle of gravity screening is increasingly becoming the mainstream in the development of similar products due to its high efficiency, stability and easy maintenance.

[0003] Under the existing technology, the drum-type automatic cat toilet based on the principle of gravity screening is composed of a plastic part and a sand pad assembled on a drum by screws or buckles to store cat litter. When the pet cat urinates and defecates, the drum rotates to achieve the effect of automatically screening the excrement.

[0004] The sand pads installed on the drum are all made of hard rubber, and clearance fit is used for easy assembly. Therefore, when the pet cat urinates, the urine will penetrate into the drum along the matching position of the drum and the sand pad and accumulate on the support seat of the whole machine. The residual smell of urine not only affects the living air environment of pet owners, but the long-term accumulation of urine also corrodes the life of the whole machine all the time. The damage of the machine will also cause great economic losses to pet owners. Utility Model Content

[0005] The main purpose of the utility model is to provide an anti-urine leakage structure of an automatic cat litter box, aiming to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model proposes an anti-urine leakage structure of an automatic cat litter box, comprising a mounting seat, a drum, a sand pad with a connecting frame and a driving mechanism, wherein the inner wall of the drum is formed with an annular surrounding bone, the connecting frame is located below the surrounding bone and elastically abuts against the inner wall of the drum, and the top wall of the connecting frame is formed with a tight abutment portion that elastically abuts against the bottom wall of the surrounding bone, so as to fix the connecting frame to the inner bottom of the drum and seal the space between the sand pad and the inner bottom wall of the drum at the same time.

[0007] The technical solution of the utility model is provided with an annular surrounding bone on the inner wall of the drum, and a tight-butting part for elastically abutting against the bottom wall of the surrounding bone is provided on the top wall of the connecting frame of the sand pad. It can be understood that the bottom space of the drum gradually shrinks with the depth. When the sand pad is installed, the connecting frame can maintain elastic abutment against the inner wall of the drum when it descends to the bottom of the surrounding bone toward the bottom space of the drum and cannot continue to descend. At the same time, the tight-butting part of the top wall of the connecting frame maintains elastic abutment against the bottom wall of the surrounding bone. The connecting frame is connected to the inner wall of the drum through the force of the tight-butting part abutting against the bottom wall of the surrounding bone. The frame is fixed in the drum, and the space between the sand pad and the bottom wall of the drum can be sealed by the elastic resistance of the tight-fitting part and the bottom wall of the surrounding bone. Compared with the traditional one, the utility model performs sealing treatment at the assembly position of the sand pad and the drum, so that urine cannot penetrate into the inside of the drum along the matching position of the drum and the sand pad and accumulate on the mounting seat, avoiding the breeding of odor and bacteria, and preventing urine from corroding the drum and the mounting seat and causing damage to the machine. The overall structure is simple, which effectively increases the service life of the automatic cat litter box and reduces the economic loss of consumers. BRIEF DESCRIPTION OF THE DRAWINGS
