Description

Technical Field

[0001] The utility model belongs to the technical field of evacuated containers, and particularly relates to an automatic vacuum pumping device for evacuated containers. Background Art

[0002] When foods such as tea, coffee, and medicinal materials are stored for a long time, they will inevitably deteriorate due to moisture absorption. Especially in southern regions, how to better store these foods so that the industrial quality retention time is longer is a problem that needs to be solved. The main reason for the moisture absorption and deterioration of foods such as tea, coffee, and medicinal materials is that there is air in the storage environment, and there will inevitably be moisture in the air, which will contact the internal foods and cause deterioration.

[0003] For this reason, people have proposed storage containers with a vacuum pumping function. Specifically, a detachable vacuum pumping device is installed on the top of the tea storage can, and the tea storage can is evacuated to make the stored tea have a longer storage time. Such as an electric vacuum tea can disclosed in CN210365049U, a circuit conduction structure and a container having the same disclosed in CN218199845U, and a vacuum storage container disclosed in CN218199983U; the above technical solutions have the following disadvantages: (1) It can only be connected to a bottle body with a convex ring at the top. The outer convex ring at the bottom of the vacuum pumping device is fitted with the inner convex ring of the bottle body to achieve tightness, and it cannot be applied to the bottle body structure with a flat cut; (2) The housing of the vacuum pumping device is integrally formed or connected by a multi-layer bolt fastening structure, and the assembly efficiency is low; (3) Since it must be applicable to the bottle body structure with an outer convex ring at the top, it can only be combined with a bottle body with a larger aperture, and its own volume is large, and it cannot be applied to a smaller bottle body with a flat cut. Therefore, in view of the above problems, it is of great significance to propose an automatic vacuum pumping device for evacuated containers. Summary of the Utility Model
