Description
Technical Field
The invention belongs to the technical field of vacuum cups, and particularly relates to a leakage-proof vacuum cup.
Background
The vacuum cup is a container made of ceramic or stainless steel and vacuum layer, the top of the container is covered tightly, the vacuum heat insulating layer can delay the heat dissipation of the liquid such as water in the container, so as to achieve the purpose of heat preservation. The thermos cup is developed from a thermos bottle, the heat preservation principle is the same as that of the thermos bottle, and people only make the bottle into a cup conveniently.
When the cup cover of the existing vacuum cup is not screwed down, hot water leakage is easy to occur, and the situation that the hot water scalds people often occurs.
The invention provides a leak-proof sealing vacuum cup, wherein one side of a protruding block is hinged to one side of a movable rod, an extending block is integrally formed on one side of the lower portion of the movable rod, the upper portion of the movable rod is inserted into an inner cavity of a groove, a fan cavity is formed in the bottom of a cup body, the top of the fan cavity is communicated with one end of a U-shaped pipe, the other end of the U-shaped pipe penetrates through the outer side wall of the cup body, the U-shaped pipe is located inside the cup body, and a fan is arranged in the fan cavity. This thermos cup inserts in the cup through the plunger, the cup can promote the extension piece, it is rotatory to make the extension piece promote the movable rod, the inner circle that promotes annular rubber circle when the upper portion of movable rod is rotatory contracts, thereby drive the inner circle shrink of annular gasbag, make annular gasbag carry out the centre gripping to the plunger, thereby accomplish the gap sealing to the plunger outer lane, even make under the bowl cover does not screw up the state, water is difficult for outside seepage also, outside the blowing off of hot-blast by the fan behind the U type pipe absorption hot water heat, improve hot water cooling speed, be convenient for the people drink hot water.
Although the thermos cup in the above-mentioned technique can prevent through the plunger that sets up that the cup from leaking, nevertheless insert the inside back of cup at the plunger, the plunger is in the state of compressing tightly with annular gasbag, and the annular gasbag that is in the interference fit state this moment is difficult to relative rotation with the plunger to make the bowl cover tighten when on the cup comparatively hard, annular gasbag also takes place easily simultaneously and scalds the damage, thereby influence the stability of thermos cup when using.
In view of the above, the invention provides the leakage-proof vacuum cup, and the leakage-proof structure in the cup body is arranged, so that the resistance generated when the cup cover and the cup body are twisted is reduced, the vacuum cup is lighter in use, the structure in the vacuum cup is simpler and is not easy to damage, the use effect of the vacuum cup is greatly improved, and the service life of the vacuum cup is greatly prolonged.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides the leakage-proof vacuum cup, and the leakage-proof structure in the cup body is arranged, so that the resistance generated when the cup cover and the cup body are twisted is reduced, the vacuum cup is lighter in use, meanwhile, the structure in the vacuum cup is simpler and is not easy to damage, the use effect of the vacuum cup is greatly improved, and the service life of the vacuum cup is greatly prolonged.
The technical scheme adopted by the invention for solving the technical problems is as follows: the leakage-proof vacuum cup comprises a cup body and a cup cover, wherein the side wall of the cup cover is in threaded connection with the outer wall of the top end of the cup body; the inner wall of the top of the cup body is connected with a pressing plate, the top wall inside the cup cover is fixedly connected with an annular sealing body, the sealing body is made of hard rubber materials, the inner and outer ring side walls of the sealing body are located in a projection area of the inner and outer ring side walls of the pressing plate in the vertical direction, and the sealing body can be driven to be gradually pressed on the top surface of the pressing plate when the cup cover is screwed with the cup body; during operation, although the vacuum cup in the prior art can prevent the cup body from leaking water through the arranged plunger, after the plunger is inserted into the cup body, the plunger and the annular air bag are in a pressing state, and the annular air bag and the plunger in an interference fit state are difficult to relatively rotate, so that the cup cover is relatively stressed when being screwed on the cup body, and meanwhile, the annular air bag is easy to be damaged by burning, so that the stability of the vacuum cup during use is influenced; when the anti-leakage vacuum cup is used, after hot water is filled in the cup body, the cup cover is screwed on the cup body, so that the bottom end of the sealing body can be driven to be pressed with the top surface of the pressure plate in the screwing process of the cup cover, thereby leading the sealing body pressed between the pressure plate and the cup cover to effectively seal the drinking water in the vacuum cup, and the sealing body is pressed by the spiral screwing of the cup cover and the cup body, so that the obstruction of the sealing body to the screwing of the cup cover and the cup body during the work is reduced, thereby the vacuum cup is more portable when in use, and simultaneously, when the cup cover is just twisted with the cup body, the bottom end of the sealing body can be effectively pressed on the pressure plate, so that the cup cover and the cup body can not leak water even if not completely screwed, meanwhile, the leakage-proof device is simple in structure and not easy to damage, and the using effect and the service life of the vacuum cup are greatly improved.
