## Abstract

The present invention provides an exhaust machine which includes a first exhaust tube, a second exhaust tube, a first closed box, a second closed box, a pipe and a motor. The first exhaust tube is connected to the first closed box and the second exhaust tube is connected to the second closed box. The pipe penetrates the first closed box and the second closed box and connects to an exhaust gas source. The pipe includes a first inner opening and a second inner opening. The motor connects to the pipe and drives the pipe to make the exhaust gas pass into the first closed box through the first inner opening or into the second closed box through the second inner opening.

## Claims

### Claim 1

A exhaust machine, comprising:
a first exhaust pipe connected to a first enclosed chamber;
a second exhaust pipe connected to a second enclosed chamber;
a extraction tube penetrating through the first enclosed chamber and the second enclosed chamber, the extraction tube being connected to an exhaust source and being provided with a first inner opening and a second inner opening; and
a pump connected to the extraction tube, the pump driving the extraction tube such that the exhaust produced from the exhaust source enters the first enclosed chamber via the first opening or enters the second enclosed chamber via the second opening.

### Claim 2 (depends on 1)

The exhaust machine of claim 1, wherein the extraction tube further comprises an inner tube and an outer tube.

### Claim 3 (depends on 2)

The exhaust machine of claim 2, wherein the pump rotates the inner tube of the extraction tube.

### Claim 4 (depends on 2)

The exhaust machine of claim 2, wherein the outer tube is provided with an outer opening being exposed to the first enclosed chamber and the second enclosed chamber.

### Claim 5 (depends on 4)

The exhaust machine of claim 4, wherein the first inner opening and the second inner opening are formed on the inner tube.

### Claim 6 (depends on 5)

The exhaust machine of claim 5, wherein the first opening is aligned with the outer opening and a pumping force is provided by the first exhaust pipe when the exhaust source produces a first gas.

### Claim 7 (depends on 6)

The exhaust machine of claim 6, wherein the second opening is not aligned with the outer opening when the exhaust source produces the first gas.

### Claim 8 (depends on 5)

The exhaust machine of claim 5, wherein the second opening is aligned with the outer opening and a pumping force is provided by the second exhaust pipe when the exhaust source produces a second gas.

### Claim 9 (depends on 8)

The exhaust machine of claim 8, wherein the first opening is not aligned with the outer opening when the exhaust source produces the second gas.
