Abstract
The utility model solves the technical scheme that its technical problem adopts: the design of movable stopper by bottle stopper ejection with reduce safety coefficient, designs this device in order to prevent inner bag air pressure excessive.Bottle stopper forms 1 by two parts, common bottle stopper 2, the slide plate of what bottle stopper was ined succession below be equipped with spring, and when the hot water temperature in inner bag is very high, air pressure is very large, and at this moment slide plate rises, and the volume in bottle is increased, thus reduction pressure, bottle stopper is not easily sprayed.The beneficial effects of the utility model are, can thermos flask be protected as much as possible intact and perfectly can protect the personal safety of surrounding when having an accident.
Description
Technical field
The utility model relates to the device of a heat insulation thermos bottle, is the bottle stopper that can increase safety coefficient.
Background technology
At present, known thermos bottle is made up of glass liner, stopper and shell, inner container of thermos bottle by vacuum state therebetween and double glazing that is silver-plated or aluminium form, glass liner plays the effect of insulation, be evacuated between two-layer glass liner and utilize vacuum state can avoid this feature of thermal convection current, the non-conductor of the busy heat of glass, internal tank then can go back to extraradial heat energy back by silver-plated glass.The hot water accomplished fluently, also because of expanding with heat and contract with cold bottle stopper can be sprayed, the steam of ejection has certain danger.
Utility model content
To spray because of expanding with heat and contract with cold cause the injured deficiency of people to overcome existing thermos flask bottle stopper, the utility model provides a kind of breakage-proof movable stopper of thermos flask, this thermos flask can in inner bag strong very large time stopper can not spray because of expanding with heat and contract with cold and hurt sb.'s feelings.
The utility model solves the technical scheme that its technical problem adopts:
1. the design of movable stopper
In order to prevent inner bag air pressure excessive by bottle stopper ejection and reduction safety coefficient, design this device.
Bottle stopper is made up of two parts
1) common bottle stopper
2) slide plate that spring is housed that bottle stopper is ined succession below, when the hot water temperature in inner bag is very high, air pressure is very large, time slide plate rise, the volume in bottle is increased, thus reduction pressure, bottle stopper is not easily sprayed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the design drawing of bottle stopper of the present utility model.
Have in Fig. 1
(1), liner holder (2), stopper (3), spring (4), slide plate
Detailed description of the invention
In FIG, after just having played boiling water, now in bottle, temperature is very high, pressure is very large, so the pressure of the inside forces slide plate upward sliding, the volume in inner bag increases, pressure reduces, until slide plate stops sliding, when the water in inner bag is after several times of drinking when air pressure is equal, the temperature of the water of the inside comparatively speaking, decrease, so the pressure now below slide plate is lower than pressure above, so slide plate is under the effect of pressure, move down until, upper and lower pressure is equal.
Can move up and down by slide plate the object reaching adjustable pressure like this, avoiding bottle stopper because of the change of pressure sprays, and avoids bottle stopper and spills and hurt sb.'s feelings.
Claims (1)
1.
increase the breakage-proof Moving bottle plug of inner bag of warm bottle inner plug slide plate, comprise bottle stopper, slide plate, spring, it is characterized in that: on the basis of existing bottle stopper (2), bottom it, connect slide plate (4) by spring (3).
