Description

Technical Field

[0001] The utility model relates to the technical field of automatic cat toilets, in particular to a roller installation structure of an automatic cat toilet. Background Art

[0002] As people's material living standards continue to improve, their requirements for spiritual life are also gradually increasing, and more and more people like to keep pet cats. Although many cat lovers like pet cats, cleaning the excrement produced by pet cats is a time-consuming and laborious task, so there are special automatic pet cat toilets that can separate the excrement produced by pet cats from cat litter through the machine, freeing the hands of pet owners.

[0003] Among the existing automatic cat toilets, the drum type automatic cat toilet based on gravity screening is becoming more and more mainstream in the development of similar products due to its high efficiency, stability, and easy maintenance. It mainly includes a main body and a drum. The drum can be pivotally mounted on the main body and driven to rotate by a driving mechanism set on the main body. The excrement produced by the pet cat relies on the drum pivoting to cooperate with the screen inside the drum to screen the cat litter and excrement, and then the excrement is concentrated and sent to the garbage box on the main body.

[0004] Since the excrement is screened by the rotation of the drum and the cat litter, the drum must rotate smoothly. The prior art generally sets a number of rollers for rolling contact with the drum at a position below the main body corresponding to the drum. However, since the roller is a movable part, a gap needs to be left at the assembly position of the roller. However, due to the addition of cat litter or the stirring of the pet cat, the cat litter falls on the main body and gets stuck in the gap between the rollers, causing the drum to rotate unsmoothly and produce abnormal noises. Therefore, many products have grooves at a position below the main body corresponding to the roller, so that the cat litter can fall directly into the main body after falling into the gap. This solution will cause cat litter to accumulate inside the machine after long-term use. The PCBA control system inside the machine is easily damaged by short circuit due to cat litter, shortening the service life of the automatic cat toilet. Utility Model Content

[0005] The main purpose of the utility model is to propose a roller installation structure for an automatic cat toilet, which aims to solve the problem of uneven drum rotation and abnormal noise caused by cat litter falling into the gap between the roller and the main body, and the problem of short-circuit damage to the internal PCBA control system caused by cat litter falling into the main body through the gap, so as to improve the service life of the automatic cat toilet.

[0006] To achieve the above-mentioned purpose, the utility model proposes a roller mounting structure for an automatic cat toilet, comprising a body and a roller pivotally mounted on the body, the body being provided with a plurality of accommodating grooves at positions corresponding to those below the roller, the accommodating grooves being open at the tops and not connected to the interior of the body at the bottoms, rollers being pivotally mounted in the accommodating grooves, the top openings of the accommodating grooves being covered with a cover body, the cover body being provided with avoidance holes at positions corresponding to those of the rollers, and the rollers partially passing through the avoidance holes and coming into rolling contact with the outer wall of the roller.

[0007] Preferably, the machine body is further provided with a cleaning groove, and the cleaning groove is communicated with the containing groove.

[0008] Preferably, the cleaning groove is in a strip shape, and one end of the cleaning groove is connected to the accommodating groove.

[0009] Preferably, the roller is pivotally mounted with a connecting shaft, and the two ends of the connecting shaft are respectively located on both sides of the roller. The position of the accommodating groove corresponding to the end of the connecting shaft is provided with a clamping groove suitable for the connecting shaft, and the clamping groove is clamped with the end of the connecting shaft to fix the connecting shaft, so that the roller can roll relative to the accommodating groove.

[0010] Preferably, the slot is snap-fitted with the end of the connecting shaft by interference fit, or the slot is formed with a limit block, and when the end of the connecting shaft is located in the slot, the limit block is kept in contact with the outer wall of the end of the connecting shaft to limit the end of the connecting shaft from leaving the slot.

[0011] Preferably, an embedding groove is formed at the top opening position of the accommodating groove, and the cover body is partially embedded in the embedding groove.

[0012] Preferably, the cover body is locked by screws or fixed to the body by a snap-on structure, or a plurality of connecting columns with slots are provided at positions on both sides of the roller corresponding to the accommodating groove, and a plug column is formed at a position corresponding to the slot on one side of the cover body close to the accommodating groove, and the plug column is fixedly inserted in the slot by interference fit to fix the cover body to the body.

[0013] Preferably, the wheel surface of the roller is inclined downward toward the middle of the drum.

[0014] Preferably, the machine body is pivotally mounted with four rollers, and the four rollers are distributed in annular intervals with respect to the machine body.

[0015] Preferably, the edge of the cover body extends outward to form a flange adapted to fit into the embedding groove, and after the cover body closes the top opening of the accommodating groove, the flange is embedded in the embedding groove.

[0016] The technical solution of the utility model is to set a plurality of receiving grooves at positions below the corresponding drum of the body of the automatic cat toilet, the opening of the receiving groove is located at the top, and the roller is pivotally installed in the receiving groove, and the cover body with the avoidance hole can be detachably installed on the body and close the top opening of the receiving groove, and at the same time, a part of the roller passes through the avoidance hole and is exposed to the outside so as to roll with the drum to achieve drum contact.
