Abstract

The utility model is an air back valve structure, comprising a casing. The utility model is characterized in that an admitting port and an exhaust port are arranged respectively on the two ends of the casing. In addition, a spatial content whose radius is larger than the admitting port and exhaust port is provided in the conical body of the casing; a sphere and a spring body is positioned in the spatial content, and thereby the air valve making the air run one way is formed, as the air-in and air-out technology. The one-way air valve is installed in the tread with an air chamber, when the tread is trampled by the feet air pressure is produced to extrude the sphere, and then the air valve forms the he air-in and air-out usage. The utility model has the advantages of simple structure, high production efficiency, and thereby the cost is reduced.

Description

A kind of air check valve structure

Technical field

The utility model relates to a kind of air check valve structure, refers to especially by a spring body and the spheroid installed in the housing, to form Non-return air valve, sees through the air pressure that the sole air chamber is produced, and reaches effects such as air inlet and exhaust.

Background technique

General Non-return air valve is a base material with plastic material (preferable with PVC) mostly, as shown in Figure 1, this air valve (A) is formed summary can be divided into headgear (A1) and sleeve pipe (A2) two-part, wherein, be provided with the baffle plate (A11) of a movable diaphragm (B) and tapering in this headgear (A1), make air only can do unidirectional air inlet or exhaust.

The diameter of this activity diaphragm (B) is greater than the perforate of sleeve pipe (A2), but perforate less than headgear (A1), when air enters air valve (A) by sleeve pipe (A2) side, will force movable diaphragm (B) to lean baffle plate (A11), and air see through the slit circulation between movable diaphragm (B) and baffle plate (A11); If air is entered by headgear (A1) side of air valve (A), then force movable diaphragm. (B) perforate of closed casing (A2), make the air can't free flow, reach the purpose of unidirectional air inlet or exhaust whereby.

Edge this, this creator feels the shortcoming that above-mentioned air valve structure is derived deeply, so be engaged in the experience that related work is accumulated for many years according to self, at the shortcoming that above-mentioned Non-return air valve is consuming time in production and cost is higher, think hard progressive space and method, there is the utility model to produce eventually, in order to the technology that promotes commodity research and development creation and the design field of evolution.

The model utility content

Main purpose of the present utility model provides a kind of air check valve, and the special tectonic by this air check valve also is filled in the sole that is provided with air chamber, and the air pressure that is produced when utilizing people to walk, as the mode of air chamber inner air exchange.

The purpose of this utility model is to realize like this, the utility model comprises housing, it is characterized in that the housing two ends respectively set out a suction port and a relief opening, in addition, the inside of housing taper body is provided with the containing space big than the bore of suction port and relief opening, one spheroid and a spring body are placed wherein, and formation can allow the air valve of air one-way flow as the technology of air inlet and exhaust.

The utility model utilizes above-mentioned constructional device, except reaching the function of air inlet or exhaust, by housing set suction port and relief opening, the bore that utilizes suction port and relief opening is less than spring body and spheroid, in order to prevent that air inversion or water from running in the air sac, reach the effect of air ventilation whereby.

The utility model is assembled in the air chamber of sole, the trample action of being done when walking by the user, make air chamber inside can produce air pressure and then extruding spheroid, allow Non-return air valve make purposes such as air inlet and exhaust, the mode that makes things convenient for inner set air chamber of sole or air bag physical efficiency to be in communication with the outside.

The utility model is simple in structure, and the manufacturing efficiency height has reduced cost.

Embodiment

Desire to reach aforementioned purpose for making the auditor can understand the utility model really, and requiredly possess special tectonic and operating technology means thereof, enumerate now that embodiment describes in detail as after, sincerely see also.

See also Fig. 2～Fig. 4, the solid that is the utility model air valve is finished figure, three-dimensional exploded view and sectional structure chart, this air check valve structure comprises a hollow casing (11), a spheroid (2) and the spring body (3) that its inside installs of arranging in pairs or groups again has the Non-return air valve (1) of air inlet and scavenging action with formation.

Air check valve structure is mainly respectively offered a suction port (12) and a relief opening (13) by a housing (11) in two ends from the above mentioned, makes air be able to circulation in housing (11); In addition, be provided with than the bore big containing space (111) of suction port (12) in the inside of housing (11) taper body with relief opening (13) mouth, place for a spheroid (2) and a spring body (3), formation can allow the air valve (1) of air one-way flow as the usefulness of air inlet and exhaust.

Please consult Fig. 5～Fig. 6 again, be the use schematic representation () and use schematic representation (two) of the utility model air valve, learn by graphic, when air is entered in the housing (11) by suction port (12), promote spheroid (2) by its air pressure, make air can be circulated to relief opening (13) and locate, allow air can do an exchange, see through a spring body (3) and be used for assistant sphere (2) and return back to the location, as the adjustment mode of control air mass flow; Otherwise, during as if air generation adverse current, the no air pressure of spheroid (2) is assisted promote spring body (3), and cause one to shrink blocking, allow air can only make one-way flow.

See also Fig. 7, it is enforcement illustration of the present utility model, be bonded to by Non-return air valve (1) on the air chamber (4) of sole, in order to form a kind of plain type pump-unit, see through the trample action that people are done when walking, make air chamber (4) be extruded, allow inside produce an air pressure, as the air ventilation mode of a kind of air inlet of sole and exhaust.

Claims

1, a kind of air check valve structure, comprise housing, it is characterized in that the housing two ends respectively set out a suction port and a relief opening, in addition, the inside of housing taper body is provided with the containing space big than the bore of suction port and relief opening, one spheroid and a spring body are placed wherein, and formation can allow the air valve of air one-way flow as the technology of air inlet and exhaust.
