Description

Two-way valve structure

The "two-way valve structure" of the present invention relates to a single-structure gas valve, which can achieve the technical field of bidirectional circulation of fluid by different actions.

Many equipment, installations and even air mattresses are equipped with check valves, pressure relief valves or associated air valves to accommodate the entry and exit of fluids. In the case of an air bed, the air valve must have an air intake function to facilitate inflation; it also needs to have a venting function to facilitate proper pressure relief, and even need to be quickly vented for CPR first aid. Conventionally, a plurality of gas valves each having a different function are used, or the structure of the gas valve is too complicated, and it is rather inconvenient to use.

Obviously, the existing valve structure is still not ideal and perfect, and there is a need for improvement. In view of this, the creators have made research on the cost case, and can use the proposal of this case to improve the shortcomings of the existing gas valve, so that the function of the gas valve can be more perfect and ideal, in line with actual needs.

In order to improve the aforementioned existing air valve, there is inconvenience or structural complexity. Miscellaneous and many miscellaneous, the main purpose of this creation "two-way valve structure" is to provide a gas valve that utilizes a single structure and can satisfy the purpose of two-way circulation of fluid by different actions; thereby achieving easy production, Easy to use, reasonable cost, able to meet actual needs and many other purposes.

In order to achieve the above object, the specific means of the present invention is: the two-way valve structure of the present invention, which comprises a body, a connecting body, a combined body and a plug body.

The main body has a ring shape, an opening is formed in the center, and a retaining ring is disposed on the outer edge. The inner end edge of the opening is semi-closed and an extension body is disposed. The extension body portion is connected to the body, but the portion is The structure has a separate fracture portion from the body; the extension body is provided with a perforation, and the perforation is provided to a diaphragm for a column assembly; the diaphragm has an area larger than the opening, and the diaphragm can be used for The opening is closed; the inner edge of the opening is provided with a concave ring.

The connecting body has one end connected to the body and the other end connected to the combined body.

The combination body is an annular body that is slightly smaller than the opening of the body. The inner side opening of the inner opening is provided with an inner ring, and the inner ring of the inner opening is provided with a convex ring.

The plug body is a circular body slightly smaller than the inner opening, the side edge ring is provided with a concave ring, and the side edge is appropriately provided with an exhaust port.

The specific means of the present invention is that the membrane can provide a function that the fluid can only enter, and the plug body is combined in the binding body, and the combined body can be used for binding to the body. When the plug body is pressed, the plug body can open the diaphragm and release the one-way restriction to achieve the purpose of discharging the fluid outward.

In view of the structural composition of the "two-way valve structure" and the functions that can be produced, the preferred embodiment of the present invention is described in detail below.

Referring to the first and second figures, the "two-way valve structure" of the present invention comprises a body 1, a connecting body 2, a combined body 3 and a plug body 4.

The body 1 has a ring shape, an opening 11 is defined in the center, and a ring 12 is disposed on the outer edge. The opening 11 is semi-closed at an inner edge and is provided with an extension body 13. The extension body 13 is partially connected to the body. 1 is connected, but a part of the structure and the body 1 have a separate breaking portion 15; the extending body 13 is provided with a through hole 131, and the through hole 131 is provided to a diaphragm 14 and a column 141 is disposed; the film The area of the sheet 14 is larger than the opening 11, and the diaphragm 14 can be used to close the opening 11. The inner edge of the opening 11 is provided with a concave ring 16. The connecting body 2 has one end connected to the side of the body 1 and the other end connected to the side of the combined body 3. The The combination body 3 is an annular body slightly smaller than the opening 11 of the body 1. The inner side opening 31 is defined in the inner side of the inner opening 31, and an inner convex ring 33 is arranged on the inner ring 31. The outer edge of the combined body 3 is disposed. There is a convex ring 32. The plug body 4 is a circular body slightly smaller than the inner opening 31. The side edge ring is provided with a concave ring 41, and a side edge is appropriately provided with an exhaust port 42.

In the present case, the plug body 4 is first inserted into the inner opening 31, and then the combined body 3 is inserted into the opening 11 of the body 1, as shown in the third and fourth figures. The concave ring 16 is formed to be fitted to the convex ring 32, and the concave ring 41 is fitted to the inner convex ring 33 to have a desired coupling relationship. The baffle 12 is for attachment to the capsule 5 of an air bed.

Normally, before the combination body 3 is inserted into the opening 11 of the body 1, the opening 11 can provide an air intake function (or intake air can be used by other air inlets); after the intake air is completed, the cover is closed. The combination 3 is closed at the opening 11. At this time, due to the internal pressure, the pressure can force the diaphragm 14 to cover the end of the opening 11 (as shown in the fifth figure) to obtain a sealing effect.

When the internal exhaust operation is required, the outside of the plug body 4 is pressed to force the plug body 4 to move slightly inward, and the concave ring 41 will be disengaged from the inner convex ring 33, so that the inner end of the plug body 4 holds the column. The inner edge of the body 141; since the extension body 13 can have displacement elasticity by the breaking portion 15, the diaphragm 14 will be pushed in and released to close the end face of the opening 11 (as shown in the sixth figure), at this time, the inside The pressure will cause the fluid to flow toward the exhaust port 42 and the outer end for the purpose of exhausting or depressurizing. When the exhaust or pressure relief is completed, it is only necessary to pull the plug body 4 out again to return to the previous backstop state.

To sum up, the "two-way valve structure" in this case uses a single structure to achieve the purpose of two-way flow of fluid through different actions, which can meet the actual needs. The technical content of this case is completely in line with the acquisition of new patents. Pieces. The case was indeed exploited in the industry and was not seen in the publication or publicly used before the application, and is not a technology known to the public. Furthermore, this case effectively solves the long-standing problems in the prior art and achieves the long-term needs of relevant users and consumers. It is proved that the new model cannot be easily completed. The case is rich in "industry useability", "novelty" and "progressiveness" as stipulated in the Patent Law. The patents are submitted in accordance with the law, and the bureau is required to investigate in detail and approve the patent as soon as possible to protect the wisdom of the applicant. Property rights, encourage innovation.

The present invention is described by the foregoing embodiments, but it is to be understood that the form and details may be varied without departing from the spirit of the invention, and will be understood by those skilled in the art. The preferred embodiment of the present invention is only one of the ways in which the present invention can be implemented in a specific manner, but is not limited thereto, and should be defined in the scope of the appended patent application.
