Vacuum cup with extremely high sealing performance
Technical Field
The invention belongs to the technical field of daily necessities, and particularly relates to a vacuum cup with extremely high sealing performance.
Background
In daily life, people pay more attention to and begin a life style of health preservation, for example, people do not drink cold water, so that the vacuum cup or the heat preservation tank becomes one of daily products which are necessary or less for each family or most people, and particularly, hot water can be taken for use in public places such as stations and airports when people go out or travel. And when going out, the thermos cup or the heat preservation tank has a heat preservation effect and a sealing effect which is also very important. Good sealing helps strengthening the heat preservation effect on the one hand, and on the other hand also improves the security to carrying, consequently, keeps warm with sealed becoming the important reference factor that people chose thermos cup or heat preservation jar. Among the current thermos cup product, most thermos cup adopts and sets up round rubber packing ring in the bowl cover, and this kind of sealed frequent use of thermos cup at any time, the screwing and unscrewing number of times of cup and bowl cover increase, and the very easy production is out of shape, and some drops easily even, influences sealed effect, and then also influences the heat preservation effect. Therefore, improvements are needed.
Some technical scheme about sealed thermos cup have also appeared among the prior art, have disclosed a thermos cup seal structure like chinese patent with application number 201811136432X, including cup and bowl cover, the cup includes cup body and rim of a cup, and the rim of a cup outer wall is equipped with first screw thread portion, and the inner wall of bowl cover is equipped with second screw thread portion, and first screw thread portion is connected with the meshing of second screw thread portion, and the top in the bowl cover is equipped with seal ring, and the top of rim of a cup can closely laminate with seal ring. The invention relates to a vacuum cup sealing structure, which has the beneficial effects that: the multi-seal structure strengthens the sealing effect, has simple structure and is convenient to produce and popularize.
Among the above-mentioned technique, the thermos cup is only sealed the thermos cup through general seal ring and threaded connection, and the structure is simple, but the sealed effect of this kind of mode is often not enough, and the laminating degree of cup and bowl cover is high inadequately, leads to the thermos cup to leak the infiltration often, leads to the fact certain puzzlement for the user.
Therefore, the invention provides the vacuum cup with extremely high sealing performance.
Disclosure of Invention
In order to make up for the defects of the prior art, the vacuum cup is sealed only through a common sealing washer and a common threaded connection, the structure is simple, but the sealing effect of the mode is often insufficient, the joint degree of the cup body and the cup cover is not high enough, so that water leakage and water seepage of the vacuum cup often occur, and certain trouble is caused to a user.
