Abstract
The utility model discloses a vacuum flask plug. The vacuum flask plug comprises a plug body provided with an air leakage assembly. When pressure inside a vacuum flask reaches a certain value, an air leakage channel is automatically opened so that air inside the vacuum flask can be conveniently exhausted, the pressure inside the vacuum flask is lowered, and the plug can effectively prevent the situation that the plug jumps due to too high pressure in the vacuum flask. The vacuum flask plug belongs to the technical field of living goods.
Description
Technical field
The utility model belongs to technical field of living goods, especially relates to a kind of thermos bottle cork that prevents that bottle stopper from jumping out from the hot water bottleneck.
Background technology
Bottle stopper is a kind of instrument in order to prevent that various volumetric flask internal objects from overflowing or heat is dispersed.Life at ordinary times with the most used be exactly thermos bottle cork.When making applying hot water bottles, careful people can find the bottle stopper plug is had in the thermos bottle of hot water in filling, and bottle stopper will jump and drop on the ground for a moment.Main cause is, thermos bottle heat in the interior water vapor body, and after you blocked bottle stopper, the many cold airs of having entered again of the empty place in thermos bottle will expand after cold air is heated at a gallop, and simultaneously, hot water also constantly produces the steam of heat.The steam of dilated cold air and heat just pushes up thermos cork and has jumped up.
Therefore it is at present required designing a preventing from the thermos bottle cork that thermos bottle mouth jumps out.
The utility model content
Technical problem to be solved in the utility model is: a kind of thermos bottle cork of jumping out from thermos bottle mouth of preventing is provided.
Technical solution adopted in the utility model is: a kind of thermos bottle cork, and it comprises the bottle stopper body, described bottle stopper body is provided with disappointing assembly.
Described bottle stopper body is provided with axially extending bore, and disappointing assembly comprises steam vent lid, upper lining lid, movable vapour bar and the little spring that resets from top to bottom, and upper lining lid is sealed on bottle stopper body axially extending bore upper end, and upper lining lid is axially arranged with upper through hole; Bottle stopper body axially extending bore lower end is provided with the lower baffle ring that radially arranges, and lower baffle ring is axially arranged with lower through-hole; The vertical activity of movable vapour bar is engaged in the lower through-hole of the upper through hole of lining lid and lower baffle ring, the little spring that resets is enclosed within outside movable vapour bar, movable vapour bar outer wall is provided with the upper baffle ring that blocks the little spring lower end that resets, described little spring and the upper baffle ring of resetting is all between upper lining lid and lower baffle ring, and reset little spring upper end and upper lining cover lower surface and offset; Movable vapour bar is provided with the steam passage that is communicated with up and down, and the upper end of described steam passage is located at movable vapour bar upper side, and movable vapour bar upper end exceeds upper lining lid, and the steam vent lid is connected to top, movable vapour bar upper end, and the steam vent lid closes snapping with upper lining cap seal.
Described movable vapour bar lower end is provided with pressure plare, and described steam passage runs through pressure plare.
The foreign-plated antirust coat of the described little spring that resets.
The beneficial effects of the utility model are: the utility model thermos bottle cork, disappointing assembly is set on the bottle stopper body, when the pressure in bottle reaches certain pressure, automatically open disappointing passage, the gas of being convenient in thermos bottle is discharged, reduce pressure of the inside of a bottle, can effectively avoid bottle stopper and jump because the bottle cavity pressure is too high.

In figure, 1, the bottle stopper body, 2, the steam vent lid, 3, upper lining lid, 4, movable vapour bar, 4.1, steam passage, 4.2, upper baffle ring, 5, the little spring that resets, 6, lower baffle ring, 7, pressure plare.
The specific embodiment
Be below the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
With reference to Fig. 1, shown in Figure 2, a kind of thermos bottle cork of the utility model, it comprises bottle stopper body 1, described bottle stopper body 1 is provided with disappointing assembly.
Described bottle stopper body 1 is provided with axially extending bore, and disappointing assembly comprises steam vent lid 2, upper lining lid 3, movable vapour bar 4 and the little spring 5 that resets from top to bottom, and upper lining lid 3 is sealed on bottle stopper body 1 axially extending bore upper end, and upper lining lid 3 is axially arranged with upper through hole; Bottle stopper body 1 axially extending bore lower end is provided with the lower baffle ring 6 that radially arranges, and lower baffle ring 6 is axially arranged with lower through-hole; The 4 vertical activities of movable vapour bar are engaged in the lower through-hole that lining covers 3 upper through hole and lower baffle ring 6, the little spring 5 that resets is enclosed within outside movable vapour bar 4, movable vapour bar 4 outer walls are provided with the upper baffle ring 4.2 that blocks little spring 5 lower ends that reset, described little spring 5 and the upper baffle ring 4.2 of resetting is all between upper lining lid 3 and lower baffle ring 6, and reset little spring 5 upper ends and upper lining cover 3 lower surfaces and offset; Movable vapour bar 4 is provided with the steam passage 4.1 that is communicated with up and down, and the upper end of described steam passage 4.1 is located at movable vapour bar 4 upper side, and movable vapour bar 4 upper ends exceed upper lining lid 3, and the steam vent lid is connected to movable vapour bar 4 tops, upper end, steam vent lid and upper lining lid 3 sealing snappings.The utility model original state as shown in Figure 1,2 sealings of steam vent lid should be on upper lining lid 3, movable vapour bar 4 mistake under the elastic force of little spring 5 that resets, the upper baffle ring 4.2 of movable vapour bar 4 lower ends is against on lower baffle ring 6, steam passage 4.1 is equivalent to be in sealing state, and reason is that the steam passage 4.1 residing die cavities in outer end are in closed state.
Described movable vapour bar 4 lower ends are provided with pressure plare 7, and described steam passage 4.1 runs through pressure plare 7.
The described foreign-plated antirust coat of little spring 5 that resets, the little spring 5 that prevents from resetting gets rusty, and pollutes the hot water in thermos bottle.The described little spring 5 that resets adopts the less spring of elastic force.The chain-dotted line with arrow that draws in Fig. 2 represents gas flow direction.
Operation principle of the present utility model is in conjunction with shown in Figure 1, to be the utility model closed state schematic diagram.When the larger pressure of the γ-ray emission in thermos bottle, gases at high pressure are by promoting pressure plare 7, with movable vapour bar 4 jack-up upwards, the compression little spring 5 that resets drives on the steam vent lid 2 on top and moves, steam vent lid 2 separates with upper lining lid 3, make the steam passage 4.1 residing die cavities in outer end be in open mode, be convenient to lose heart, reduce the air pressure in thermos bottle, realize the exhaust action, as shown in Figure 2.After exhaust, under the effect of the little spring 5 that resets, movable vapour bar 4 and steam vent lid 2 reset to original state.
The utility model arranges disappointing assembly on bottle stopper body 1, when the pressure in bottle reaches certain pressure, automatically open disappointing passage, the gases at high pressure of being convenient in thermos bottle are discharged, reduce pressure of the inside of a bottle, can effectively avoid bottle stopper to jump because of the gas hypertonia in thermos bottle bottle chamber.
