Abstract
The utility model relates to an explosion-proof thermos bottle cork, which comprises a circular cylinder cork body, wherein an air guide channel is processed inside the cork body, a lower opening of the air guide channel is disposed on the bottom surface of the cork body, an upper opening of the air guide channel is arranged on the top surface of the cork body, the air guide channel is divided into two vertical channels with two ends communicated, the inner diameter of the upper section channel is larger than that of the lower section channel, a ball valve is installed inside the upper section channel, the diameter of the ball valve is larger than the inner diameter of the lower section channel, and the ball valve is connected with the top portion of the upper section channel through a spring. When the pressure in the thermos bottle is small, the ball valve inside the thermos bottle cork is in closed state, falls on an opening of the lower section channel to seal the opening, and accordingly prevents hot water inside the thermos bottle continuously releasing heat; when the thermos bottle is filled with hot water, the pressure inside the thermos bottle increases, then vapor can push and open the ball valve and the spring to disperse out from the upper section channel, and then the pressure inside the thermos bottle lowers to lead the ball valve to reset to seal the lower section channel, thereby sealing the channel, and completing one air-releasing and pressure-reducing operation. The explosion-proof thermos bottle cork has the advantages of reasonable structure, convenience, practicality, simple technique, delicate appearance and the like.
Description
Technical field
The utility model relates to a kind of hot-water heating apparatus, especially a kind of anti-fried plug of thermos.
Background technology
As everyone knows, make hot water with thermos flask after, run into slight external force effect, thermos flask also very easily bursts.This is that the pressure in the kettle increases because after making hot water, and the thermos flask inner bag is in lasting stress, small vibrations also can be broken the stress balance of inner bag, and these high-temperature gases and pressure can't discharge from plug of thermos, can only oppress inner bag, burst thereby cause.Study carefully its above-mentioned cause of accident, that is that present plug of thermos can't release pressure.For this reason, but we provide a kind of new-type plug of thermos of release pressure to solve the problems referred to above.
Summary of the invention
The purpose of this utility model provides a kind of anti-fried plug of thermos, is used to solve that common plug of thermos can't be got rid of pressure of the inside of a bottle and the problem that causes easily exploding.
For achieving the above object, the anti-fried plug of thermos of the utility model comprises the truncated cone-shaped cock body, processes air guide channel in cock body, and the air guide channel under shed is arranged on the cock body bottom surface, and upper shed is arranged on the cock body end face; Air guide channel is divided into vertical two ends threads a pipe mutually, and the upper end internal diameter of the pipeline is greater than the lower channel internal diameter, and pipe interior is laid ball valve in the upper end, and the ball valve diameter is greater than the lower channel internal diameter; Be connected by spring between the top of ball valve and cock body upper end pipeline.
After adopting said structure, when pressure of the inside of a bottle hour, the ball valve of plug of thermos inside is in closure state, drops on the opening part of lower channel, realizes sealing, and avoids the interior hot water continuation of a bottle heat release; After filling hot water in the bottle, pressure of the inside of a bottle increases, and steam just can back down ball valve and spring, sheds from the pipeline of upper end, treats that pressure of the inside of a bottle decline spring just can make ball valve reset, and shuts lower channel, realizes sealing, and finishes the once decompression task of exitting.
Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, convenient and practical, technology is simple, profile is exquisite, can keep the inside and outside pressure balance of bottle, and avoid bursting, the scald accident.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the anti-fried plug of thermos of the utility model.
Number in the figure: 1 is that cock body, 2 is that air guide channel, 3 is that ball valve, 4 is spring.
The specific embodiment
As shown in Figure 1, the anti-fried plug of thermos of the utility model comprises truncated cone-shaped cock body 1, processing air guide channel 2 in cock body 1, and air guide channel 2 under sheds are arranged on cock body 1 bottom surface, and upper shed is arranged on cock body 1 end face; Air guide channel 2 is divided into vertical two ends threads a pipe mutually, and the upper end internal diameter of the pipeline is laid ball valve 3 greater than the lower channel internal diameter at the upper end pipe interior, and ball valve 3 diameters are greater than the lower channel internal diameter; Be connected by spring 4 between the top of ball valve 3 and cock body 1 upper end pipeline.
Claims (2)
1, a kind of anti-fried plug of thermos comprises truncated cone-shaped cock body (1), it is characterized in that: processing air guide channel (2) in cock body (1), and air guide channel (2) under shed is arranged on cock body (1) bottom surface, and upper shed is arranged on cock body (1) end face; Air guide channel (2) is divided into vertical two ends threads a pipe mutually, and the upper end internal diameter of the pipeline is laid ball valve (3) greater than the lower channel internal diameter at the upper end pipe interior, and ball valve (3) diameter is greater than the lower channel internal diameter.
2, anti-fried plug of thermos according to claim 1 is characterized in that: be connected by spring (4) between the top of pipeline on ball valve (3) and the cock body (1).
