Specific embodiment
The present invention will be further described with reference to the accompanying drawing, but protection scope of the present invention is not limited to following institute
It states.
As shown in Figure 1, embodiment one, including main body 1, main body 1 are equipped with pressure-vaccum port, the first air inlet and exhaust outlet,
The pressure-vaccum port, the first air inlet and exhaust outlet are communicated with 1 inner cavity of main body, and first air inlet and exhaust outlet are separately connected
First breather cheek valve 3 and one-way exhaust valve 8, the pressure-vaccum port are connect with orifice reducer 2, and air inlet is used for gas when air-breathing
Into exhaust outlet is for gas discharge when blowing.
As described in Figure 2, embodiment two further include the second air inlet in main body 1, and second air inlet is arranged first
The opposite side of air inlet, the second air inlet are communicated with 1 inner cavity of main body, and are connect with the second breather cheek valve 9, the first breather cheek valve
3, the second breather cheek valve 9 and one-way exhaust valve 8 and the main body 1 are integrally formed.
As shown in figure 3, embodiment three, first breather cheek valve 3, the second breather cheek valve 9 and one-way exhaust valve 8
It is independent check valve and is connect respectively with main body 1.
It is provided with the first filter device 4 on the outside of first breather cheek valve 3 and the first air inlet junction, prevents sky
Impurity enters in device in gas；The first valve 5 is provided on the inside of junction, control gas unidirectional enters.
It is provided with the second filter device 10 on the outside of second breather cheek valve 9 and the second air inlet junction, is prevented
