The garbage can is a container for storing dirt and dirt in people's life, and is also a refraction of social culture.
The garbage can be divided into a public garbage can and a household garbage can in use occasions. The garbage containing mode can be divided into an independent garbage can and a classified garbage can. The processed materials can be classified into plastic trash cans, stainless steel trash cans, ceramic trash cans, wooden trash cans, cement trash cans, pulp trash cans, and the like. The opening modes include an open type, a cover-opening type, a treading cover-opening type, an induction type (infrared ray) and the like.
According to the research in various cities, people have low evaluation on the sanitation condition around the garbage can in the living area, the satisfactory rate is 33.2%, and the unsatisfactory rate is 66.8%. Because people flow in the urban community is large, the quantity of garbage is correspondingly large, the types of garbage are increased, and the frequency and the degree of dirtiness of the garbage can are higher than those of other places.
The clean inefficiency of current garbage bin exists and washs the leak: in some places, the garbage can is not cleaned in time, so that the garbage can has the problems of dirt, odor and the like, people only throw the garbage around the garbage can without wanting to get close to the garbage can, and vicious circle occurs. The existing garbage cleaning mode mainly adopts simple high-pressure water washing, but the cleaning effect is not ideal, and water resource waste is easily caused, so that a brand-new garbage can cleaning method is needed to solve the problems.
