With reference to Fig. 3, barometric control unit 100 can comprise: housing, has and run through through hole 103 that this housing forms to allow to introduce extraneous air; Movable link 110, be installed in this housing, for example, and (towards this through hole) is mobile and leave this through hole and move (can make progress and move down) forward, so that the level error of the air pressure inside based on this reservoir vessel 1 and external pressure (pressure reduction) and optionally open and close this through hole 103; Supporting member 150, is fixed in this housing, and separates with this movable link 110; And elastic component 130, by regularly between this movable link 110 and this supporting member 150.
This housing can be hollow tubular.This housing can have upper surface and open lower surface, and this upper surface runs through and is formed with through hole 103, and this lower surface is sealed and is inserted in reservoir vessel 1.This housing also can be formed tubular or square.
Continuation is with reference to Fig. 3, can be based on movable link 110 and supporting member 150 and be split into the first inner space A, the second inner space B and San inner space C in the inside of this housing.Here, the periphery of movable link 110 can be attached to the first contact site 105a of the inner peripheral surface of housing.The first inner space A and the second inner space B can change due to the bending of movable link 110.
Fig. 4 A, Fig. 4 B illustrate the border between the first inner space A and the second inner space B.When reservoir vessel 1 is under suitable air pressure inside, (see Fig. 4 A), movable link 110 can not be bent downwardly (or the distortion of up concave type ground), and between the first inner space A and the second inner space B, can present a smooth border thus.Yet when the air pressure inside of reservoir vessel 1 is during lower than external pressure (seeing Fig. 4 B), movable link 110 can be bent downwardly, and presents the border of a bending between the first inner space A and the second inner space B.
This housing can comprise cylindrical portion 105, and cylindrical portion 105 is formed hollow round tubular.The inner peripheral surface of cylindrical portion 105 comprises the first contact site 105a and the second contact site 105b, and movable link 110 is attached on this first contact site, and supporting member 150 is attached on this second contact site.
With reference to Fig. 3 and Fig. 5 A, Fig. 5 B, movable link 110 can comprise: open/close portion 111, in order to open and close through hole 103; Deformable part 113, in order to allow open/close portion 111 to move; And elastic component fixed part 115, in order to fix this elastic component 130.
As shown in Fig. 3 to Fig. 5 A and Fig. 5 B, open/close portion 111 can open and close through hole 103, and this through hole is sealed after being connected to reservoir vessel 1 and becomes air intake at this housing, and extraneous air is introduced into via this air intake.Through hole 103 can in response to open/close portion 111 downwards and move up and be opened and closed.Therefore, open/close portion 111 preferably can be formed by rubber, to seal airtightly through hole 103.
The deformable part 113 of movable link 111 can be implemented as circular rubber parts, and this rubber parts is attached on the inner peripheral surface of cylindrical shell.In the situation that the periphery of deformable part 113 is fixed to this housing, this deformable part 113 can be moved up and down in response to the moving up and down of open/close portion 111 forming in deformable part 113 central area.
As shown in Fig. 4 A, Fig. 4 B and Fig. 5 A, Fig. 5 B, moving up and down of open/close portion 111 can realize by deformable part 113.Deformable part 113 can be formed by rubber, thereby can up concave type ground distortion (being bent downwardly) also return to subsequently original shape, and the periphery of deformable part 113 is fixedly attached on the first contact site 105a of this housing simultaneously.
Deformable part 113 can be identical plane in the cross section (for example circular) of shape and housing, and makes for the rubber of distortion by having predetermined elasticity coefficient.Here, the predetermined elasticity coefficient of deformable part 113 can be depending on and is desirably in the air pressure keeping in reservoir vessel.
With reference to Fig. 3 and Fig. 4 A, Fig. 4 B, deformable part 11 can comprise a plurality of pore 113a, and these pores run through deformable part 113 and form along the thickness direction of this deformable part.Movable link 110 can be made by rubber.
Referring to Fig. 4 A, Fig. 4 B and Fig. 5 A, Fig. 5 B, elastic component 130 can be fixed to the elastic component fixed part 115 on the central area of the lower surface that is positioned at movable link 110.Elastic component 130 can have ，Gai lower end, top and bottom can by supporting member 150 support to prevent its move up and down ，Er Gai upper end movable link 110 up concave types be out of shape (or being bent downwardly) and restore and compressed and extend downwards and while moving up.Elastic component 130 can be the spring with predetermined elasticity coefficient.
Air pressure conservation condition is presetted according to the difference of the air pressure inside of reservoir vessel 1 and external pressure, and the coefficient of elasticity that air pressure conservation condition can be based on deformable part 113 and the coefficient of elasticity of elastic component 130 are determined.Especially, with reference to Fig. 3 and Fig. 4 A, Fig. 4 B, when elastic component 130 is spring, can be by elastic-restoring force F
kutilize spring constant to set the air pressure inside to be kept of reservoir vessel 1.
With reference to Fig. 4 A, Fig. 4 B, the air pressure inside of the reservoir vessel 1 of (seeing Fig. 4 A) when deformable part 113 is maintained at flat condition may be higher than preset air pressure.Thus, the upper surface 111a of open/close portion 111 can close through hole 103, to maintain the airtight conditions of reservoir vessel 1 inside, thereby can keep reliably the air pressure inside (seeing Fig. 4 A) of reservoir vessel.
Yet, for example, when the air pressure inside of reservoir vessel 1 lower than preset air pressure (becomes, 0.8atm) produce draught head (, pressure reduction between reservoir vessel 1 inside and outside) time, the power that this draught head produces is greater than the elastic-restoring force that the coefficient of elasticity because of movable link 110 and elastic component 130 produces, open/close portion 111 can be pushed down, and can make deformable part 113 sink and generation strain (seeing Fig. 4 B).
With reference to Fig. 4 B, when extraneous air is introduced into reservoir vessel 1 due to produced draught head, extraneous air can be introduced into reservoir vessel 1 by the through hole 113a of deformable part 113.When the air pressure inside of reservoir vessel 1 suitably increases in response to the introducing of extraneous air, open/close portion 111 can be by the elastic-restoring force of movable link 110 and elastic component 130 and is moved, thereby again seals airtightly through hole 103.
So, when the air pressure inside of reservoir vessel 1 is reduced to less than preset air pressure, extraneous air can be by being introduced into according to the barometric control unit of an one exemplary embodiment, to keep preset air pressure based on coefficient of elasticity.
For example, when expectation makes the air pressure inside of reservoir vessel be maintained at about 0.8atm, can be by the coefficient of elasticity of the coefficient of elasticity of movable link 110 and elastic component 130 is carried out to suitable combination, and will move member 110 and elastic component 130 is designed to have the elastic-restoring force because of the draught head elastic recovery between atmospheric pressure (1atm) and the air pressure of 0.8atm.
Because elastic component 130 is implemented as spring, so can estimate elastic-restoring force F by calculating spring constant
k(F
k=k(spring constant) * X(standoff distance)).
With reference to Fig. 3 and Fig. 4 A, Fig. 4 B, supporting member 150 can comprise: elastic component fixed part 151, in order to fixing elastic component 130; And a plurality of pores 153, along the thickness direction of supporting member 150, run through this supporting member 150 and form.
Supporting member 150 can by plastics or similarly rigid material make, it is firm and can not be moved up and down.Supporting member 150 can be fixed on the second contact site 105b of inner peripheral surface of this housing.
The San inner space C that is positioned at supporting member 150 belows can be connected to the inner space of reservoir vessel 1.When open/close portion 111 is opened through hole 103, extraneous air can pass the first inner space A, with the pore 153 of the pore 113a via movable link 110 and supporting member 150, is introduced in the inner space of reservoir vessel 1.
According to another one exemplary embodiment shown in Fig. 6, supporting member 150 can comprise: framework 151a, is fixedly attached on the second contact site 105b of housing; And a plurality of brace summer 151b, from framework 151a, towards the central part of this supporting member 150, extend.By this structure, supporting member 150 can be fixedly fastened on elastic component fixed part 151 on the inner peripheral surface of housing.
At each supporting leg 151b, extend and be connected under the state of elastic component fixed part 151, the interval between adjacent supporting leg 151b can form pore 153.
When the size of pore 153 is larger, the extraneous air being introduced in the second inner space B can flow in the reservoir vessel 1 as San inner space C swimmingly.Therefore, supporting member 150 can be implemented by framework 151a and supporting leg 151b.
Therefore,, for the air pressure inside that prevents reservoir vessel 1 is excessively lower than external pressure, can utilizes external pressure that the air pressure inside of reservoir vessel 1 is suitably raise, and remain on the atmospheric pressure state of expectation.

When the elastic component 130 of barometric control unit 100 is spring, adjustable springs constant, thus can open and close valve (that is, barometric control unit 100) in predetermined pressure level.In addition, can make spring constant different according to being desirably in the preset air pressure keeping in reservoir vessel 1, realize thus a kind of device being opened under pressure.
For example, when the air pressure inside of reservoir vessel 1 is reduced to less than the Reference pressure of 0.8atm, barometric control unit 100 can be opened to allow to introduce extraneous air.Can prevent that like this air pressure inside is reduced to lower than preset air pressure (this air pressure be expectation maintained), and avoid being in advance stored in the situations such as article in reservoir vessel are corrupt and dry.
In addition, in order to prevent that the air pressure inside of reservoir vessel is reduced to less than preset air pressure, and make to be stored in article in this reservoir vessel under suitable atmospheric pressure state, spring constant can be conditioned to keep this preset air pressure.
That is, under the air pressure inside state of suitable reservoir vessel 1, open/close portion 111(rubber button) can on the elastic force of spring (that is, elastic component 130), be pushed away, to seal airtightly through hole 103, thus the airtight conditions of maintenance reservoir vessel 1.Yet, air pressure inside at reservoir vessel 1 (is for example reduced to less than preset air pressure, under state 0.8atm), movable link 110 can be larger at the elastic-restoring force of the ratio spring (being elastic component 130) producing because of pressure reduction the effect of power under by up concave type be out of shape (being bent downwardly), and open/close portion 111 can move down.Thus, through hole 103 can be opened to allow to introduce extraneous air.Here, can set by regulating spring constant the predetermined air pressure inside of reservoir vessel 1.
With reference to Fig. 4 A, when the air pressure inside of reservoir vessel 1 and the difference of atmospheric pressure are within the scope of preset air pressure, as the spring of elastic component 130, can go up and press open/close portion 111 by its elastic-restoring force, to close through hole 103.
On the other hand, with reference to Fig. 4 B, when the air pressure inside of reservoir vessel 1 is reduced to less than preset air pressure, deformable part 113 can because of the difference up concave type of this air pressure inside and atmospheric pressure be out of shape (or being bent downwardly).Thus, open/close portion 111 can move down and push elastic component 130, thereby makes elastic component 130 can have elastic-restoring force F
k1.
After through hole 103 is opened due to moving of open/close portion 111, extraneous air can be introduced in reservoir vessel 1 via the pore 113a of movable link 110 and the pore 153 of supporting member 150, thereby improves the air pressure inside of reservoir vessel 1.When air pressure inside reaches preset air pressure, open/close portion 111 can be by the elastic-restoring force of elastic component 130 and is moved up, to close through hole 103, thus gastight closing reservoir vessel 1.
As mentioned above, barometric control unit can prevent being reduced to lower than preset air pressure of air pressure inside of reservoir vessel according to an embodiment of the invention, thereby improves the freshness that is stored in the vegetables in reservoir vessel.
