Description

Technical Field

[0001] This utility model relates to the field of garbage bag sealing technology, and specifically to an automatic bag sealing device. Background Technology

[0002] Currently, trash cans generally require manual placement of trash bags, and once full, the bags need to be tied up manually before being taken to a centralized collection station for disposal. Each time a trash bag is placed or trash is retrieved, the lid of the trash can needs to be removed, and then the trash bag needs to be placed over the opening of the can or the opening of the trash bag needs to be closed and tied tightly, which is not very convenient.

[0003] Therefore, in the prior art, people have invented trash cans that can automatically change bags, such as the Chinese Utility Model Patent No. CN202322188332.4, which discloses a bag sealing device and a trash can having the same. The device includes a housing with a through opening and a first groove located circumferentially around the through opening, which is suitable for placing a bag; a bag collecting assembly disposed within the housing, one end of which is pivotally connected to the housing, and the other end sliding along the first groove; the bag collecting assembly being switchable between a first state and a second state; and a bag sealing assembly connected to the housing, located in the middle of the bag collecting assembly, which is switchable between an open state and a closed state. When the bag collecting assembly is in the first state, the bag sealing assembly is in the open state to open the bag; when the bag collecting assembly is in the second state, the bag sealing assembly is in the closed state to seal the bag.

[0004] The bag-gathering component gathers the open bags, and the bag-sealing component seals the gathered bags, achieving fully automatic bag packing. However, the packing mechanism is complex, and the chute design is prone to jamming and preventing the bags from closing properly. Therefore, further improvements to its structure are needed. Utility Model Content
