Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
Embodiment: referring to accompanying drawing 1～accompanying drawing 9, a kind of new micro air valve, comprise motor 1, be fixed on the cylindrical promotion valve 2 of the output shaft 1-1 of motor, be fixed on motor 1 and cylindrical shell 3, guide sleeve 4 between shell 3 and promotion valve 2, promote valve 2, guide sleeve 4, shell 3 is coaxial with the output shaft 1-1 of motor respectively, at the circumferential surface that promotes valve 2, radially there is a protruding short column 2-1, promoting valve 2 is matched with in the body of guide sleeve 4, short column 2-1 be overlapped on guide sleeve 4 towards promoting on the end face of valve 2, guide sleeve 4 towards promoting there is one section of helicoid 4-1 on the end face of valve 2, helicoid 4-1 comprises helicoid least significant end 4-1-1, helicoid most significant end 4-1-2, helicoid least significant end 4-1-1 has a vertical transitional surface 4-2 with guide sleeve 4 between the end face of promotion valve 2, helicoid most significant end 4-1-2 overlaps with the end face towards promoting valve 2 of guide sleeve 4, at the circumferential surface of guide sleeve 4, be evenly equipped with two cylinder 4-3 along guide sleeve 4 axial directions, shell 3 has circular groove 3-1 along axle center, guide sleeve 4 is matched with in circular groove 3-1, in the peripheral surface of circular groove 3-1, be evenly equipped with two chute 3-1-1 along circular groove 3-1 axial direction, two cylinder 4-3 of guide sleeve 4 are matched with respectively in two chute 3-1-1, lower end edge at circular groove 3-1 radially passes a breathing pipe 5, shell 3 is run through at the two ends of breathing pipe 5.
In the end of shell 3, be evenly equipped with two through hole 3-2 that communicate with circular groove 3-1.
