## Abstract

An integrated air valve structure includes a main body and two air valves. The main body is formed with two air passages not communicated with each other, a plurality of through holes disposed corresponding to the two air passages, and two valve mounting seats. One valve mounting seat is disposed corresponding to one of the through holes, the other valve mounting seat is disposed corresponding to two of the through holes belonging to the two air passages. The two air valves are disposed on the two valve mounting seats, each air valves includes an air plug facing at least one of the through holes, a valve body assembled with one of the two valve mounting seats for the air plug to move therein, and a coil disposed on the valve body for generating magnetic force to change a position of the air plug.

## Claims

### Claim 1

An integrated air valve structure, comprising:
a main body, formed with two air passages, a plurality of through holes, and two valve mounting seats, the two air passages not communicated with each other, the plurality of through holes respectively disposed corresponding to the two air passages, one of the two valve mounting seats being disposed corresponding to one of the plurality of through holes, the other one of the two valve mounting seats disposed corresponding to two of the plurality of through holes respectively belonging to the two air passages; and
two air valves, disposed on the two valve mounting seats, each of the two air valves comprising an air plug facing at least one of the plurality of through holes, a valve body assembled with one of the two valve mounting seats and being configured for the air plug to move therein, and a coil disposed on the valve body for generating magnetic force to change a position of the air plug based on energization condition;
wherein one of the two air valves is configured to determine communication between the two air passages to achieve air intake, the other of the two air valves is configured to determine whether one of the two air passages communicates with external to achieve exhaust, and the two air valves are configured to jointly determine whether the integrated air valve structure holds air pressure.

### Claim 2 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein in one of the two air valves used for exhausting, the air plug comprises an exhaust passage, and the valve body comprises an exhaust hole communicated with the exhaust passage.

### Claim 3 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein one of the two valve mounting seats disposed corresponding to one of the two air valves for exhausting comprises an exhaust hole.

### Claim 4 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein each of the two air valves comprises an elastic member for restoring the air plug.

### Claim 5 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein each of the two air valves comprises an airtight ring disposed on the valve body and contacting one of the two valve mounting seats.

### Claim 6 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein the air plug comprises a plug body acted by the coil, and a plug cover disposed on the plug body and facing at least one of the through holes.

### Claim 7 (depends on 6)

The integrated air valve structure as claimed in claim 6, wherein the main body is formed with a partition wall that separates the two air passages.

### Claim 8 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein the main body is formed with at least one auxiliary airtight ring disposed corresponding to one of the through holes.

### Claim 9 (depends on 1)

The integrated air valve structure as claimed in claim 1, wherein the main body is formed with a partition wall that separates the two air passages.
