Also be provided with the rubber-like sealing ring in the described valve pocket, the sealing snare is on this spool and between sealing portion and this gas vent.
Described spool is pegged graft with this button and is cooperated.
Described housing has opening, and this button is arranged on this opening, and this button has bead, and this bead is buckled on the edge of this opening inboard.
Described valve body also has installing port, and this installing port is sealed by valve gap, and this valve gap and this valve body are fixed, and this valve gap has cylinder, and this elastomeric end is enclosed within on the cylinder of this valve gap, and its other end is enclosed within on the cylinder of this spool.
Described elastomer is spring and laterally places.
Described valve body has two at least, and spool is also to there being at least two.
Described each spool all cooperates with this button.
Described housing is made up of upper shell and lower house, and the shell chamber is formed between this upper shell and this lower house.
The invention has the beneficial effects as follows that this manual safety valve is connected between the air bag and source of the gas of pressure for pneumatic massager, when normally using, under elastomeric elastic force, the gas vent of sealing closed valve; When being in an emergency, press the button, then spool overcomes elastomeric elastic force and laterally moves, and sealing is removed the sealing to gas vent, and the gas in the valve pocket can release moment, can effectively protect user.

Fig. 2 is the front view of present embodiment manual safety valve;
Fig. 3 and Fig. 4 are respectively Fig. 2 along the B-B direction with along the cutaway view of A-A direction.
The specific embodiment
As shown in Figures 1 to 4, present embodiment manual safety valve comprises housing 1, two valve bodies 2, two valve gaps 3, button 4, two spools 5 and two elastomers 6.This housing 1 is made up of upper shell 11 and lower house 12, forms shell chamber 13 between this upper shell 11 and this lower house 12.Each valve body 2 all has air inlet 21, gas outlet 22 and gas vent 23, and this air inlet 21, gas outlet 22 and gas vent 23 are communicated with by valve pocket 24, and promptly valve body 2 is roughly three-port structure.Each valve body 2 also has an installing port 25, and this installing port 25 is sealed by valve gap 3, and this valve gap 3 is fixing with this valve body 2, and this valve gap 3 is provided with cylinder 31.This upper shell 11 has the opening 111 that laterally runs through, this button 4 this opening 111 of packing into, this button 4 has the bead 41 of external diameter greater than these opening 111 bores, and this bead 41 fastens the edge of this opening 111 in the inboard, thereby can effectively prevent to extract button 4 out this opening 111.Two spools 5 cross the gas vent 23 of two valve bodies respectively and have the gap with gas vent 23, each spool 5 has first 51 that is positioned at shell chamber 13 and the second portion 52 that is positioned at valve pocket 24, this first 51 and this button 4 are pegged graft and are cooperated and realize the interlock of this button 4 and this spool 5, and this second portion 52 has the sealing 521 of external diameter greater than gas vent 23 bores.The second portion of this spool 52 also has cylinder 522, and each elastomer 6 is all laterally placed, and the two ends of each elastomer 6 are enclosed within respectively on the cylinder 31 of the cylinder 522 of this spool and this valve gap, and this elastomer 6 can be at transversal stretching, and it is as existing spring.All be with O-ring seals 7 on the second portion 52 of each spool, but sealing circle 7 has elasticity and compressive deformation, and sealing circle 7 places between sealing 521 and the gas vent 23.During normal the use, under the elastic force effect of elastomer 6,, prevent that the gas in the valve pocket 24 from leaking by sealing circle 7 these gas vents 23 of sealing; When needing emergency unchaining pressure, press the button 4, then spool 5 elastic force that overcomes elastomer 6 laterally moves, and removes the sealing of gas vent 23, and the gases at high pressure in the valve pocket 24 can release moment.This laterally is the direction of motion of button.
When this manual vent valve used, the air inlet 21 of valve body connected source of the gas by trachea 8, and the gas outlet 22 of valve body connects air bag by trachea.During normal the use, gas vent 23 sealings of valve body, the gases at high pressure in the source of the gas are transported to air bag, by the gas-pressure massaging of air bag realization to human body; In emergency circumstances, press the button, then gas vent 23 is removed sealing, and gas is discharged to ambient atmosphere by the shell chamber.
This utility model manual safety valve comprises the housing with shell chamber, at least one valve body that is arranged at this shell intracavity and the spool corresponding with valve body, this valve body has air inlet, gas outlet, gas vent and is communicated with the valve pocket of this air inlet, gas outlet and gas vent, be provided with elastomer in this valve pocket, on this housing button is installed, this spool cross this gas vent and place this elastomer and this button between, this spool has the part that is positioned at valve pocket, and this part is provided with the sealing of external diameter greater than this gas vent bore.This valve body can have one, two or more, all corresponding spool of each valve body.Each valve body separates setting or is wholely set.For the sealing of this gas vent, both can seal by the position of the one-body molded external diameter that goes out on this spool greater than the gas vent bore, this position is described sealing; Also can seal by the parts that other establishes, these parts are located on this spool, and its external diameter also need be greater than the bore of this gas vent, and these parts are sealing ring as described above, and promptly the sealing circle is equivalent to described sealing.
Above content be in conjunction with concrete preferred implementation to further describing that this utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For this utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from this utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
