Background technique

Existing product is mainly based on plastic kettle plug and wooden pot plug, and after thermos flask makes hot water, hot water heating is empty Gas expands air, and due to the airtightness of pot plug, air pressure is flown up in pot gallbladder, and gas can not exclude in time, causes quick-fried pot existing As.

Utility model content

The utility model provides a kind of explosion-proof pot plug, to solve defect in the prior art.

The utility model is achieved by the following technical programs:

Explosion-proof pot plug, including shell, shell up and down two sides be open, housing central section periphery be fixedly mounted bulge loop, bulge loop with Shell is structure as a whole, and pot portion beyond the Great Wall is fixedly mounted in upper part of the housing inner wall, opens up outlet respectively at left and right sides of pot plug upper top Hole, the bulge loop inner bottom surface left and right sides open up placing groove respectively, and placing groove inner bottom surface is respectively fixedly connected with stretch cord one end, stretch cord Diaphragm is fixedly mounted in the other end jointly, and four equally distributed ventholes are opened up among diaphragm top surface, and lower part of the housing inner wall is fixed Pot plug lower part is installed, opens up four equally distributed air inlets respectively on the outside of pot plug bottom face.

Explosion-proof pot plug as described above, the diameter of the venthole are greater than the diameter of air inlet.

A circle sealing strip is fixedly mounted in explosion-proof pot plug as described above, the bulge loop bottom surface.

Explosion-proof pot plug as described above, the sealing strip are made of resistant to high temperature, harmless material.

Explosion-proof pot plug as described above, the upper part of the housing, bulge loop top are rounded structure.

Explosion-proof pot plug as described above, the upper part of the housing periphery are equipped with anti-skid chequer.

The utility model has the advantages that: when using the utility model, when rapidly rising in the air pressure short time in pot, air-flow Enter in shell via the air inlet on pot plug lower part, air-flow can be such that diaphragm moves up at this time, and extra gas passes through diaphragm On venthole enter pot beyond the Great Wall in portion, then pot plug is discharged via the venthole on pot beyond the Great Wall portion；After excessive gas is all discharged, Diaphragm is fallen after rise under the action of stretch cord, and diaphragm is bonded with pot plug lower top, guarantees that good heat insulation effect, stretch cord can Ensure the position that diaphragm is fallen after rise, to avoid diaphragm position entanglement and heat losses.The utility model structure is simple, by bottle stopper Design is to control the variation of air pressure in thermos flask, to guarantee that thermos flask will not explode, and leakproofness effect is good, so that the guarantor of thermos flask Temp effect keeps good.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is Some embodiments of the utility model, for those of ordinary skill in the art, in the premise of not making the creative labor property Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Explosion-proof pot plug, as shown, including shell 1, about 1 two sides of shell are open, and 1 middle part periphery of shell is fixedly mounted Bulge loop 2, bulge loop 2 are structure as a whole with shell 1, and 1 upper inside wall of shell is fixedly mounted pot portion 3 beyond the Great Wall, pot 3 top surface of portion or so beyond the Great Wall Two sides open up venthole 4 respectively, open up placing groove 5 respectively at left and right sides of 2 inner bottom surface of bulge loop, 5 inner bottom surface of placing groove is fixed respectively 6 one end of stretch cord is connected, diaphragm 7 is fixedly mounted jointly, opens up four among 7 top surface of diaphragm and is uniformly distributed for 6 other end of stretch cord Venthole 8,1 lower inner wall of shell is fixedly mounted pot plug lower part 9, opens up four respectively on the outside of pot plug bottom face and be uniformly distributed Air inlet 10.When using the utility model, when rapidly rising in the air pressure short time in pot, air-flow is via on pot plug lower part 9 Air inlet 10 enter in shell 1, air-flow can be such that diaphragm 7 moves up at this time, and extra gas passes through the venthole on diaphragm 7 8 enter pots beyond the Great Wall in portion 3, then pot plug is discharged via the venthole 4 on pot beyond the Great Wall portion 3；After excessive gas is all discharged, in elastic force Diaphragm 7 is fallen after rise under the action of rope 6, and diaphragm 7 is bonded with 9 top surface of pot plug lower part, guarantees good heat insulation effect, stretch cord 6 can Ensure the position that diaphragm 7 is fallen after rise, to avoid 7 dislocation of diaphragm and heat losses.The utility model structure is simple, by bottle stopper Design to control the variation of air pressure in thermos flask, to guarantee that thermos flask will not explode, and leakproofness effect is good, so that thermos flask Heat insulation effect keeps good.

Specifically, gas in thermos flask is after air inlet 10, venthole 8 from venthole 4 by being discharged, when discharge, needs fast Speed, timely, diameter of the diameter of venthole 4 described in the present embodiment greater than air inlet 10.The diameter of venthole 4 is greater than air inlet 10 diameter facilitates gas to be rapidly discharged in time.

Specifically, bulge loop 2, which is located at thermos flask mouth, goes out outside, the contact of the two is easy to have the gap and be lost heat, the present embodiment A circle sealing strip is fixedly mounted in 2 bottom surface of bulge loop.A circle sealing strip is fixedly mounted in 2 bottom surface of bulge loop, so that pot plug and pot mouth Contact it is even closer, avoid the heat losses of hot water.

Further, sealing strip is contacted with pot mouth, water, and high temperature is easy that sealing strip is made to change and generate shadow to human body It rings, sealing strip described in the present embodiment is made of resistant to high temperature, harmless material.Sealing strip be it is resistant to high temperature, to people The harmless material of body is made, and satisfies the use demand, and service life is high.

Further, user takes pot plug through common hand, is easy to be gone out to draw by the seamed edge on 1 top of shell, 2 top of bulge loop Hurt, 1 top of shell described in the present embodiment, 2 top of bulge loop are rounded structure.1 top of shell, 2 top of bulge loop are fillet Structure improves safety when using.

Further, when user removes pot plug, hand is inconvenient to exert oneself, 1 top of shell described in the present embodiment Periphery is equipped with anti-skid chequer.Anti-skid chequer is capable of increasing the frictional force between user's hand and shell 1, is easy to use.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc. With replacement；And these are modified or replaceed, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution The spirit and scope of scheme.
