TECHNICAL FIELD

[0001] The present application relates to a garbage can, in particular to a garbage bag folding method, a folding device and a garbage can. BACKGROUND

[0002] The disposal of garbage has become an essential part of people's lives. The traditional garbage can only has the capacity to store garbage and cannot meet people's needs.

[0003] In order to pursue a more convenient experience, some intelligent garbage cans are proposed in the prior art, for example, an invention application with application publication number CN 108584238 A discloses a garbage bag packaging mechanism and an intelligent garbage can, and a utility model patent with authorization announcement number CN 210012170 U discloses a garbage bag packaging mechanism and an intelligent garbage can. The above two garbage cans can automatically open or close the garbage throwing opening before and after throwing garbage, and can also automatically package and change bags when the garbage in the garbage bag reaches a certain amount, greatly facilitating people's disposal of garbage.

[0004] The existing intelligent garbage can still has the following problems:

[0005] When folding the garbage bag, at least two groups of folding rods push the garbage bag to the designated folding position along different directions on the periphery of the garbage bag. Such folding method not only occupies a large space, resulting in a large size of the garbage can, but also has a complex structure and a high production cost. SUMMARY

[0006] The present application aims to overcome the above-mentioned problems and provide a garbage bag folding method which uses a new way to pull and gather the garbage bag, thereby greatly reducing the occupied space, reducing the size of the garbage can, and having a simple structure and a low production cost.

[0035] Referring to Figures 1-4 , the garbage bag folding device further comprises an auxiliary mechanism (not shown in the figure), and the auxiliary mechanism comprises an air extractor; the air extractor is arranged below the mounting base 1. In this way, when the garbage bag starts to be folded, the air extractor generates negative pressure to suck the garbage bag and press it on the pull belt 2, so that the pull belt 2 can take the garbage bag to the folding port 1-2 to perform the folding work.

[0036] Referring to Figures 1-4 , the garbage bag folding method of the embodiment comprises the following steps:

[0037] The air extractor generates negative pressure to suck the garbage bag and press it on the pull belt 2.
