Abstract

The invention discloses a double-bag combined one-way valve and a pair of venting shoes thereof. The double-bag combined one-way valve comprises a small bag which is adopted as a film and a large bag which is adopted as a valve body. The small bag is installed in the large bag. One end of an air inlet pipe respectively communicates with the connection centers of the large bag and the small bag, one end of an air outlet pipe communicates with the connection center of the large bag, and the other end of the small bag is adopted as an air inlet channel which is formed by adhering two thin films. When the pressure in the air inlet pipe is larger than the pressure outside the bag, the air inlet channel which is formed by adhering two thin films is conducted, or when the two thin films are adhered together, the air inlet channel is closed. The invention further discloses the venting shoes which are provided with the double-bag combined one-way valve, wherein the middle soles and the large soles of the venting shoes are provided with grooves which are matched with the double-bag combined one-way valve. The invention has the following beneficial effects: the sensitivity is high, and the reverse air quantity is small, so that the valve can be started between zero and negative pressure MPa 0.01.

Description

Two bags are made up Non-return air valve and ventilated footwear thereof

Technical field

Non-return air valve that the present invention relates to be used in the ventilated footwear and ventilated footwear thereof particularly make air in air valve, do one-way flow, can not let the device that air flows backwards and the ventilated footwear of application thereof.

Background technology

At present, footwear are divided into two kinds with Non-return air valve both at home and abroad, and a kind of is that two hemispheric software goods are docking together, and as flap, hemisphere was washed open by malleation direction air-flow when air valve body received negative pressure, and air flows through; When receiving malleation, hemisphere sealing, the air-flow blocking-up, the shortcoming of this air valve is, and when in the air impurity being arranged, air valve blocking-up air-flow function reduces, and simultaneously, this air valve is large-minded.

A kind of in addition is spring plug-back type, good sealing effect when this spring for valve pressure is big, but air valve sensitivity is not high; Spring pressure hour, highly sensitive, but sealing effectiveness is bad, causes conflicting.

Summary of the invention

To the deficiency of above-mentioned technology, the present invention provides a kind of two bag combination Non-return air valve and ventilated footwear thereof, and this air valve is highly sensitive, and is narrow-minded, just can start between the negative pressure MPa0.01 zero.

To achieve these goals, the technical scheme that the present invention taked is:

Two bags of combination Non-return air valves comprise that pouch is sleeved in the sack as the pouch of iris action with as the sack of valve body; Air inlet pipe one end is connected the center with sack with pouch respectively and communicates, and escape pipe one end is connected the center with sack and communicates, and the other end of pouch is two film adhered inlet channels; When the pressure in the air inlet pipe greater than outside during the pressure of bag, two film adhered inlet channel conductings, otherwise; Two is together film adhered, and inlet channel is closed.

The length that air inlet pipe is stretched out in pouch be little bag length 1/5 within.

Described pouch is to hotly join the bag shape that forms path.

A kind of ventilated footwear, the ventilated footwear that two bag combination Non-return air valves are installed, the middle end of ventilated footwear, be provided with the groove that matches with two bag combination Non-return air valves with the big end.

Beneficial effect of the present invention: highly sensitive, narrow-minded, just can start between the negative pressure MPa0.01 zero.

The specific embodiment

As shown in the figure, two bags of combination Non-return air valves comprise as the pouch 2 of iris action with as the sack 1 of valve body; Pouch 2 is sleeved in the sack 1, and air inlet pipe 3 one ends are connected the center with sack with pouch 2 respectively and communicate, and escape pipe 4 one ends are connected the center with sack 1 and communicate; The other end of pouch 2 is two film adhered inlet channels, when the pressure in the air inlet pipe 3 greater than outside during the pressure of bag 1 (valve pocket), two film adhered inlet channel conductings; Otherwise two is together film adhered, and inlet channel is closed.After pin is stepped on the air chamber of ventilated footwear, is produced certain air pressure, in air inlet pipe 3, there is air-flow to come in, wash two films of fitting open, air-flow is discharged through escape pipe 4 after getting into sacks 1 from pouch 2 again.Behind the pine pin, present negative pressure in the air chamber, the air pressure of air inlet pipe 3 and pouch 2 is during less than the air pressure of outer bag 1, and the inlet channel of pouch 2 is closed, and the film of pouch tightly fits together, and ventilating air passage is closed.Pouch 2 is that two films hotly join the bag shape that forms path, only is that film just can be fitted.The sack wall is thicker, for swelling the shape cavity.Air inlet pipe 3 one ends hotly join with sack 1 and pouch 2 respectively and are connected the center and communicate; Outer the hotly joining with sack 1 of escape pipe 4 is connected the center and communicates, and so just can not leak gas, and is fixed together.The length that air inlet pipe 3 is stretched out in pouch 2 is 1/5 of pouch 2 length, is difficult for longly, and air-flow is blocked more easily.

Claims

1. two bags of combination Non-return air valves is characterized in that, comprise as iris action pouch (2) and as the sack (1) of valve body; Pouch (2) is sleeved in the sack (1), and air inlet pipe (3) one ends are connected the center with sack with pouch (2) respectively and communicate, and escape pipe (4) one ends are connected the center with sack (1) and communicate; The other end of pouch (2) is two film adhered inlet channels; When the pressure in the air inlet pipe (3) greater than outside during the pressure of bag (1), two film adhered inlet channel conductings, otherwise; Two is together film adhered, and inlet channel is closed.

2. two bag combination Non-return air valves as claimed in claim 1 is characterized in that, the length that air inlet pipe (3) is stretched out in pouch (2) be pouch (2) length 1/5 within.

3. two bag combination Non-return air valve as claimed in claim 1 is characterized in that described pouch (2) is for hotly joining the bag shape that forms path.

4. a ventilated footwear is characterized in that, the ventilated footwear of the described two bag combination Non-return air valves of any claim of claim 1-3 is installed, and the middle end of ventilated footwear is provided with the groove that matches with two bag combination Non-return air valves with the big end.
