Description

Technical Field

[0001] The utility model relates to the technical field of intelligent trash can structures, and particularly relates to an automatic packing trash can with negative pressure bag laying. Background Art

[0002] With the acceleration of the modern life rhythm, people are increasingly pursuing a more efficient and convenient lifestyle. Intelligent and automatic trash cans have emerged in response to user needs. An intelligent trash can is a high-tech new product integrating machinery, optics, and electricity. It adopts advanced microcomputer control chips, infrared sensing detection devices, mechanical transmission parts and other components, which work together to enable the trash can to have the function of automatic operation and the characteristic of intelligent recognition of user intentions. For example, by setting an infrared induction device, it can recognize that the user arrives in the area where the trash can is located, and the trash can will automatically open the lid by itself, facilitating the user to throw away trash. And the user can put trash without touching any part of the trash can, preventing cross-infection, being environmentally friendly and hygienic.

[0003] In addition to automatically opening and closing the lid, the functions of intelligent trash cans are numerous, such as automatic movement, obstacle avoidance, garbage classification, automatic bag changing, automatic packing of garbage bags, etc. Among them, in the existing automatic bag-changing function, when laying a garbage bag into the accommodation cavity of the trash can, the commonly used principle is: evacuating the accommodation cavity to form a negative pressure environment, so that the garbage bag can be evenly unfolded and attached to the wall of the accommodation cavity, automatically completing the laying of the garbage bag without manual operation.

[0004] Most trash cans on the current market are made of plastic materials. This material is prone to deformation in the middle parts of the four sides of the barrel body due to load or long use time. Once deformed, it may cause misalignment when the lid and the barrel body are closed, and the fit is not tight. And this problem of too large fit clearance not only affects the overall aesthetics of the trash can, but also may reduce the use performance. Especially in the automatic bag-laying function, if the sealing performance between the barrel body and the lid is insufficient, air leakage may occur during the air suction process. Air leakage will cause an ineffective negative pressure environment inside the trash can, thus affecting the unfolding and attachment of the garbage bag. This not only prolongs the time of automatic bag laying, but also may cause the garbage bag not to be fully spread to the bottom of the barrel, affecting the loading efficiency and use experience of the trash can.
