Description

Garbage can

Technical Field

The invention belongs to the technical field of garbage cans, and particularly relates to a garbage can.

Background

A trash can, also known as a waste bin or bin, is a container for holding trash. Most of the garbage bags are made of metal or plastic, and when the garbage bags are used, the garbage bags can be pricked up and discarded. The garbage can is a container for storing dirt and dirt in people's life and is also a refraction of social culture, most garbage cans are covered to prevent peculiar smell of garbage from dispersing, some garbage cans can be opened by feet, most household garbage cans are placed in a kitchen to be convenient for placing kitchen wastes, some families are respectively placed in main rooms, and the garbage cans in some recreation grounds are specially designed into lovely characters.

The existing garbage can is usually used for containing garbage by using a continuous garbage bag without break points, and after the garbage bag is filled with garbage, the garbage bag is sealed and fused by a closing device and a hot melting device which are fixed in the garbage can. In the prior art, the extending length of the garbage bag is unique when the bag is replaced every time, and when a user is not full of the garbage bag and needs to clean the garbage bag, the closing device and the hot melting device operate on the garbage bag at a fixed length, so that part of the garbage bag which is not filled with garbage is wasted to a certain extent; when the quantity of the garbage bags loaded by a user is too large, the closing device and the hot melting device are difficult to operate on the garbage bags at fixed length, so that the phenomena of difficult sealing and fusing occur. In addition, the existing closing-in device usually adopts a plurality of driving motors to cooperate to seal the garbage bag, thereby not only occupying larger space, but also increasing the complexity of the closing-in device and increasing the production cost.

For example, publication No. CN110510295A discloses a trash can, which includes a can body, which can be stably seated on the ground; the barrel cover is rotatably arranged at the rear end of the top of the barrel body through a turnover connecting piece; and the lifting heat sealing device is arranged in the garbage can so as to seal and fuse the garbage bag at a proper position. According to the garbage can with the liftable heat sealing device, the closing position and the fusing position of the garbage bag can be adjusted through the lifting unit, so that the waste of the garbage bag is avoided, and the problem that the garbage bag is difficult to seal and fuse due to overlarge garbage amount is solved. In addition, the binding off unit in this application just can close off the disposal bag through a binding off step motor, and its simple structure, operation are stable, have not only occupied less installation space, have still saved manufacturing cost, should use widely in a garbage bin field.
