The specific embodiment
A kind of cyclical breathing blower fan system as shown in Figure 1, comprise blower fan 1, motor 2, with the coaxial power transmission shaft 2 12 that is connected and is used to drive the power transmission shaft 1 of valve 1 and valve 28 and be used to drive valve 3 11 of the power output shaft of motor 2, the air inlet of described blower fan 1 is connected with interior conduit 13, the outlet of described blower fan 1 is connected with circulating line 10, circulating line 10 sidewalls are provided with coupled logical yard piping 1 and yard piping 27, described power transmission shaft 1 is arranged on yard piping 1 and the yard piping 27, described power transmission shaft 2 12 is arranged on the circulating line 10, the part of described power transmission shaft 1 between yard piping 1 and yard piping 27 is equipped with axle sleeve helical gear 1, described power transmission shaft 2 12 ends and axle sleeve helical gear 1 match axle sleeve helical gear 29 are installed, described valve 1, valve 28 and valve 3 11 are arranged at yard piping 1 respectively, yard piping 27 and circulating line 10 inside.
As shown in Figure 1, valve 1, valve 28 and valve 3 11 are by double layer of metal dish and intermediate rubber layer constitute up and down.
The bearing of support fixation effect has been installed between power transmission shaft 1 and power transmission shaft 2 11 and the duct wall as shown in Figure 1.
As shown in Figure 1, be connected by shaft coupling between motor 2 power output shafts and the power transmission shaft 1.
