Embodiment

Now with regard to the structure composition of Bidirectional Air Valve structure of the present utility model, and the effect of can be generated, coordinate accompanying drawing, enumerate One preferred embodiment of the present utility model describes in detail as follows.

Head is referred to shown in Fig. 1 and Fig. 2, Bidirectional Air Valve structure of the present utility model, and it includes a body 1, one connection Body 2, a combination 3 and a cock body 4.

The foregoing body 1, slightly shape, center offer an opening 11 in a ring, and outer rim is provided with a baffle ring 12, the opening 11 1 Interior ora terminalis is semiclosed and is provided with an ennation 13, and the partial structure of ennation 13 is connected with the body 1, but partial structure with this Body 1 has the fracture 15 of separation；A perforation 131 is equipped with the ennation 13, the perforation 131 is supplied to the one of a diaphragm 14 141 groups of cylinder puts use；The area of the diaphragm 14 is more than the opening 11, and the diaphragm 14 can be closing the opening 11；Foregoing this is opened 11 inner rings of mouth are provided with a scrobicular ring 16.The connector 2, one end are connected to by the body 1, and the other end is connected to by the combination 3. The combination 3, it is the annular solid of an opening 11 for being slightly less than the body 1, an inner opening 31 is offered inside the combination 3, should The inner loop of inner opening 31 is provided with an internal projecting ring 33, and the outer rim of combination 3 is provided with a bulge loop 32.The cock body 4, it is slightly less than for one The round of the inner opening 31, lateral margin is equipped with a scrobicular ring 41, and the appropriate place of lateral margin is equipped with an exhaust outlet 42.

When the utility model is implemented, first cock body 4 is filled at the inner opening 31, combination 3 is then filled in into the body 1 again Opening 11 at, i.e., such as Fig. 3 and Fig. 4.Form that the scrobicular ring 16 is chimeric with bulge loop 32, scrobicular ring 41 is chimeric with internal projecting ring 33, and then have There is preferable marriage relation.The baffle ring 12 is being incorporated at the utricule 5 of an air bed.

Under normality, before the combination 3 is not filled in also at the opening 11 of the body 1, the opening 11 can provide air inlet effect (or using other inlet charges also can)；After completing air inlet, cover the combination 3 and closed at the opening 11, now, by There is pressure in inside, the pressure energy forces the diaphragm 14 to be covered on the end of opening 11 (such as Fig. 5), to obtain the closing of check Effect.

When needing that operation is exhausted with regard to inside, to the external pressure of cock body 4, the cock body 4 is forced to move inward slightly, it is recessed Ring 41 will be disengaged from the internal projecting ring 33, cause the inner of cock body 4 to hold the inner edge of cylinder 141；Because the ennation 13 passes through fracture Portion 15 and can have displacement elasticity, therefore diaphragm 14 will be released sealing process (such as Fig. 6) to the end face of opening 11 by interior push away, Now, internal pressure can be such that fluid is flowed towards exhaust outlet 42 and outer end, to obtain the purpose of exhaust or pressure release.When the row of completion Gas or pressure release, it is only necessary to will draw playback outside cock body 4 again, you can return to previous non-return state.

In summary, Bidirectional Air Valve structure of the present utility model, it utilizes single structure, reaches fluid by different actions The purpose that can be two-way circulated, actual demand can be met.Technology contents of the present utility model, which comply fully with, belongs to taking for new patent The condition of obtaining.The utility model is industrially utilized really, had not been seen publication before application or had openly been used, and non-for public affairs The technology that crowd is known.Also, the utility model effectively solves the problems, such as long-term existence in the prior art and reached used in connection with Person and the demand of long term consumer, obtaining evidence the utility model can not be readily accomplished.The rich tool patent statute of the utility model The condition such as industry applications, novelty and progressive, propose patent application in accordance with the law, your office's explicit example for reference earnestly asked, examine authorize early.

Though the utility model is described by previous embodiment, but still its form of alterable and details, in not departing from this reality Reached with new spirit, and the personage by being familiar with this skill can be appreciated that.Foregoing preferred embodiment of the present utility model, only For one of by way of being embodied principle of the present utility model, but system is not limited thereto, should be according to claims Define and be defined.
