Description

Automatic packing bin with flexible band to shrink bag opening The present invention belongs to the field of trash can technology and, specifically, relates to an automatic sealing trash can that shrinks the opening of a bag using a flexible band. With social development and improvements in living standards, the demand for waste disposal is gradually increasing. Traditional trash cans present various inconveniences during use; for instance, incomplete seals on bags can cause foul odors to spread, and the process of manually tying the bags is unsanitary and cumbersome. Furthermore, when the lid is opened, the contents inside may be exposed or visible to the user; if personal items such as diapers or sanitary pads are present, this can cause visual and olfactory discomfort. For these reasons, driven by advancements in social science and technology, there is a growing demand for trash cans in terms of functionality, such as preventing the spread of odors, protecting against infection, safeguarding privacy, and providing airtight isolation. To solve these problems, trash cans capable of automatically sealing trash bags are gradually appearing on the market, and these trash cans have significantly improved the level of automation in waste disposal. These trash cans typically use one or more pressure rods/pressure plates to press the opening of the trash bag against the edge of the opening to seal it, and then a sealing device cooperates with the pressure rods/pressure plates to complete the sealed packaging. For example, prior art, Chinese Patent Publication No. CN106564717B, discloses "device and method for automatically heat-sealing a trash bag in a trash can," which describes a process in which a clamp plate moves toward a heating module under the propulsion of a driving mechanism, the opening of the trash bag closes when the clamp plate contacts the heating module, and then the heating module operates to fuse the opening of the trash bag. However, the aforementioned conventional technology still has many shortcomings in actual application. (1) The device structure is complex, so multiple components such as sliding blocks, guide rails, clamp plates, and synchronous pulley sets must be installed, making control relatively complex and manufacturing costs high. (2) Both the clamp plate and the heating module are made of rigid material, and the contact area between them is relatively large. This helps to increase sealing efficiency, but excessive heating can easily damage the garbage bag, which can affect the sealing effect and subsequent processing. (3) Because the material of the garbage bag is light and thin, it can easily get caught in the corners of the pressure plate or pressure rod, so the opening may not be properly sealed, or the garbage bag may be directly damaged, which may degrade the user experience. (4) Most pressure plates/pressure rods have a main body structure in the form of an elongated rod, and the side of the pressure plate/pressure rod that contacts the heating module is a flat structure. If the pressure plate/pressure rod bends, it causes deformation of the flat structure; this deformation prevents the garbage bag from being sufficiently sealed against the heating module after compression, which leads to a sealing failure. This not only affects the sealing effect but also lowers the reliability of the packaging and the effectiveness of actual use. Therefore, to solve the above problem, there is an urgent need for an automatic sealing trash can that shrinks the bag opening with a flexible band.
