Embodiment Construction

[0023] The spiral blower fan device of the present invention will be further described in detail in conjunction with the accompanying drawings and specific embodiments:

[0024] figure 1 It is a side view showing the structure of the first embodiment of the helical blower fan device according to the present invention. Such as figure 1 As shown, the spiral fan device according to the present invention is composed of a rotating shaft 11, a sleeve 12, blades 13 and a fan casing 14. The rotating shaft 11 is combined on the driving motor and rotates together with the driving of the motor. The long The cylindrical sleeve 12 is fixed on the rotating shaft 11, and the blade 13 spirals from one end of the sleeve 12 to the other end along the direction of the rotating shaft. The outside of the track is a hollow cylindrical shape with both ends open.

[0025] Two vanes 13 are formed on the outer peripheral surface of the sleeve 12 with a phase difference of 180 degrees, and the spiral...

Abstract

The invention provides a helical blowing fan device and comprises axis of rotation, sleeve, blade and shell of fan. The axis of rotation is on the actuating motor and circumvolve with the drive of the actuating motor. The long columnar sleeve is fixed on the axis of rotation. The blade covers the sleeve from one end to the other end. The circumferential surface of the sleeve circumvolving along the steering wheel of the axis of rotation is helical and the pitch of screws lambda 1 of the suction side is larger than the pitch of screws lambda 2 of the discharge side. The shell of the fan covers the outside of the blade and is hollow cylindrical form with hatches at the two ends. The suction side of sleeve is added to by helical auxiliary leaves of suction side from the middle of sleeve to the end of suction side of sleeve. In addition, the end of the suction side of shell of the fan is declining.

Description

technical field [0001] The present invention relates to the field of helical fan devices, in particular to a helical fan device that allows air to flow axially to obtain high air volume and high air pressure in household electrical appliances such as air conditioners or other manufacturing equipment. Background technique [0002] Household appliances such as air conditioners of the prior art or ventilation systems of factory equipment are provided with many types of blowing fans for forcing blowing air. Such various types of blowing fans are divided into axial flow blowing fans and circular center blowing fans according to the flow characteristics of the blowing air. [0003] Axial flow blower fan is a blower fan whose air flow is parallel to the rotation axis. This kind of fan has the characteristics of generating a lot of flow but relatively low pressure. [0004] Like the center-shaped blower fan in the prior art, although the flow at the inlet of the blade is generally ...
