Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the present invention is described in further detail.
Embodiment one:
The present embodiment one provides a kind of vent valve, and it includes upper cover, lower cover and elastomer.
This upper cover has upper cavity, gas outlet and gas vent, and this upper cavity is formed by upper cover side side walls collapse,
Gas outlet connects with upper cavity with gas vent.This lower cover has lower chamber and air inlet, and lower chamber is by lower cover one
Side side walls collapse is formed, and air inlet connects with lower chamber.
Upper cover is fixedly connected in the way of upper cavity and lower chamber are relative with lower cover, and elastomer is clamped at upper cover
And between lower cover, upper cavity and lower chamber being divided into upper chamber and lower chamber, elastomer has passage,
Upper chamber is connected by this passage with lower chamber.
Wherein, the gas vent of upper cover connects with upper chamber and forms the normally opened check valve leading to the external world, lower cover and bullet
Gonosome forms lower chamber at passage and leads to the normally closed check valve of upper chamber, when lower chamber internal gas pressure is more than upper
During air chamber internal gas pressure, elastomer deforms upon to upper chamber direction and blocks normally opened check valve, opens normally closed unidirectional
Valve.
Therefore the elastic deformation of elastomer be can pass through thus normally opened check valve and the opening and closing of normally closed check valve realized,
Thus realizing the function of air inlet and venting, this structure is the structure of Purely mechanical, it is not necessary to consume electric energy.
This upper chamber is formed by the outer surface depressions of at least one in upper cover and elastomer, only can be the most completely
Upper cover side outer surface depressions, and enclose formation with elastomer；Or also can be only by the appearance of elastomer side
Caving in face, and encloses formation with upper cover, and such as elastomer can be for structure this shown in Fig. 6；Again or,
Upper cover and outer elastomeric surface can also all there is depression, thus enclose formation.In like manner, lower chamber by lower cover and
In elastomer, the outer surface depressions of at least one is formed, and can be only lower cover side outer surface depressions the most completely,
And enclose formation with elastomer；Or also only by the outer surface depressions of elastomer side, and can enclose with lower cover
Being formed, such as elastomer can be for structure this shown in Fig. 6；Again or, it is also possible to outside lower cover and elastomer
All there is depression on surface, thus encloses formation.

Lower chamber b1 connects.
As it is shown in figure 5, upper cover 1 and lower cover 3 fixing connection in the way of upper cavity a1 and lower chamber b1 is relative
Connecing, this elastomer 2 is clamped between upper cover 1 and lower cover 3, is split by upper cavity a1 and lower chamber b1
Open form becomes upper chamber a and lower chamber b.Elastomer 2 has passage 21, upper cavity a1 and lower chamber b1
Connected by this passage 21.And the upper end of boss 32 pushes against elastomer 2 and blocks leading on elastomer 2
Pore 21.
Owing to two air chambers are only connected by the passage 21 on elastomer 2, and the boss 32 on lower cover 3
Push against elastomer 2 and block passage 21, therefore upper lower chamber being separated.When compressed gas is from lower cover 3
When air inlet 31 enters lower chamber b, along with compressed gas increases, in lower chamber b, pressure increases, and forces bullet
Gonosome 2 upwards produces deformation, owing to normal condition lower convex platform 32 top is slightly higher than the plane of elastomer 2,
Elastomer 2 is had a pretightning force, therefore in the upwards deformation process of elastomer 2, first blocks
The gas vent 12 of lid 1, the most just makes elastomer 2 depart from boss 32, and gas is subsequently from passage 21
Enter in upper chamber a, then flow out through gas outlet 11.When compressed gas stops entering lower chamber b, the therapeutic method to keep the adverse QI flowing downwards
The air pressure of room b declines, the air pressure of the upper chamber a air pressure more than lower chamber b, and this elastomer 2 is made at pressure
With lower recovery initial position, boss 32 pushes against elastomer 2, seals passage 21, and elastomer 2 departs from venting
Mouth 12, blocked gas vent 12 is opened, and carries out Rapid degassing.This vent valve of the application is Purely mechanical
, it is not necessary to consume electric energy.
In order to ensure to block gas vent before or while passage 21 is opened in intake process further
12, it is also possible to allow the upper end of boss 32 push against elastomer 2 and make elastomer 2 local from lower chamber b1 to epicoele
Body a1 deforms upon, and this elastomer 2 is more than at the height raised up to upper cavity a1 side from lower chamber b1
Or inlet end and elastomer 2 distance equal to gas vent 12, so, in elastomer 2 deformation process,
Can first block gas vent 12, then open passage 21, or gas vent 12 and passage 21 are for open simultaneously.
And in the present embodiment, the inlet end of gas vent 12 then uses from upper cover 1 to lower cover 3 direction projection
Tubular structure, in order to control the distance of inlet end and elastomer 2.
Wherein, elastomer can use laminated structure as Figure 1-5, and it may be used without knot as shown in Figure 6
Structure, in figure 6, the surrounding raised central portion depression of elastomer 2a forms cavity.
Upper cover mentioned in above-described embodiment one and two, lower cover, upper cavity, lower chamber, upper chamber and
Lower chamber is the most only combine the orientation restriction that the accompanying drawing of the present embodiment offer is carried out, it is clear that upper cover,
Lower cover also can be set up in parallel left and right, and owing to vent valve is the relatively small object of volume, therefore user can
Being rotated at random its orientation, upper and lower orientation 90-degree rotation i.e. becomes left and right and is set up in parallel, left and right is set up in parallel
90-degree rotation i.e. becomes setting up and down, and for the ease of statement, setting up and down and left and right are arranged by the application
In mode, each parts are all defined as above-below direction, such as upper cover, lower cover, upper cavity, lower chamber, upper chamber
