Abstract
The utility model relates to a jump prevention thermos bottle plug, wherein, a circular platform hole is arranged in a wood stopper in the longitudinal direction; a spherical body is put into the circular platform hole; the surface of the wood stopper is covered with an upper cover which is provided with a riser vent at the surface. When a person fills the bottle with hot water, the air temperature in the bottle rises, thereby causing the air pressure to increase; when the wood stopper is plugged, gas enters into the circular platform hole and contacts with the spherical body; with the pressure action, the gas opens the spherical body, and then the gas is discharged, so as to reduce the inner pressure and avoid the wood stopper from being ejected out. The jump prevention thermos bottle plug has the advantages of reasonable structure, and convenient, safe and reliable use, as well as ensures the wood stopper from being ejected out of the thermos bottle, so as to ensure the heat insulation effect to be more ideal.
Description
Technical field
The utility model relates to a kind of matching product of thermos bottle, especially a kind of anti-jump thermos flask plug of jumping of can preventing.
The technical background thermos flask is the insulation articles for use that people often use in daily life, and it can help people to keep the temperature-resistant of bottle interior hot water.But the stopper of present thermos flask mostly is wooden, has problems such as light weight, easy activity, and after filling hot water, the pressure in the bottle is much larger than external pressure, and therefore frequent generation bottle stopper is ejected the phenomenon of thermos flask, has brought the deuce to pay to people.So we are sought after a kind of bottle stopper that can not be ejected thermos flask and this type of problem occurs solving.
Summary of the invention
The purpose of this utility model provides a kind of anti-jump thermos flask plug, is used to solve common stopper because pressure is former thereby the problem of quilt ejection thermos flask.
For achieving the above object, the anti-jump thermos flask plug of the utility model comprises the truncated cone-shaped stopper, vertically has a round platform hole in stopper, round platform hole great circle at stopper upper surface, roundlet at lower surface; In the round platform hole, put into spheroid; Be covered with the loam cake that the surface has air-vent on the stopper surface.
After adopting said structure, the user is filling hot water and beyond the Great Wall behind the stopper, because temperature raises and causes internal pressure to increase in the bottle, when internal pressure during much larger than external pressure, air pressure can back down the spheroid at place, stopper round platform hole, emission gases, spheroid falls automatically and blocks the round platform hole afterwards, avoids a bottle interior temperature to reduce.
The utility model has the advantages that: rational in infrastructure, esy to use, safe and reliable, can guarantee that stopper is not ejected thermos flask by pressure, make heat insulation effect desirable more.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the anti-jump thermos flask plug of the utility model.
The specific embodiment
As shown in Figure 1, the anti-jump thermos flask plug of the utility model comprises truncated cone-shaped stopper 1, vertically has a round platform hole 2 in stopper 1, round platform hole 2 great circles at stopper 1 upper surface, roundlet at lower surface; Put into spheroid 3 in round platform hole 2, spheroid 3 quality are less than stopper 1 quality; Be covered with the loam cake 4 that the surface has air-vent on stopper 1 surface.Wherein, spheroid 3 be elastomeric material or glass material all can, spheroid 3 diameters are between the 2 minimum and maximum diameters of round platform hole.After the user fills hot water in the thermos flask, air themperature in the kettle raises, and causes air pressure to become big, the user beyond the Great Wall behind the stopper, gas can enter round platform hole 2 and contact with spheroid 3, because pressure inside is much larger than external pressure, gas can back down spheroid 3, after spheroid 3 is backed down, internal gas discharges, make internal pressure reduce, at this moment aperture is blocked in the spheroid 3 round platform hole 2 that can fall back automatically, avoids a bottle interior temperature to reduce.
Claims (2)
1, a kind of anti-jump thermos flask plug comprises truncated cone-shaped stopper (1), it is characterized in that: in stopper (1), vertically have a round platform hole (2), round platform hole (2) great circle at stopper (1) upper surface, roundlet at lower surface; Put into spheroid (3) in round platform hole (2), spheroid (3) quality is less than stopper (1) quality, and spheroid (3) diameter all can between the minimum and maximum diameter in round platform hole (2).
