Ceiling fan and method for large-range full-coverage blowing

Abstract

The invention provides a ceiling fan and a method for large-range full-coverage blowing. The ceiling fan comprises a ceiling fan power body, the top end of the ceiling fan power body is hinged to one end of a rigid connecting member, the other end of the connecting member is hinged to a fixed connecting block which is fixedly connected on an ascending and descending nut, and the ascending and descending nut is mounted on a spiral ascending and descending rod which is vertical fixed on a ceiling of the ceiling fan power body; a motor in the ceiling fan power body is controlled through a forward and reverse rotation control circuit, and when the motor rotates forwards, the ascending and descending nut spirally ascends along a thread on the spiral ascending and descending rod; when the motor rotates reversely, the ascending and descending nut descends along the thread on the spiral ascending and descending rod. On the basis that existing dynamic balance of the ceiling fan is maintained, blowing range is changed when a rotating shaft of the ceiling fan moves up and down along the spiral ascending and descending rod, so that no blowing dead angle exists in the whole large range, and more uniformity in blowing of each position is realized.

Description

technical field [0001] The invention belongs to the field of daily necessities, and relates to a ceiling fan, in particular to a ceiling fan and a method for covering and blowing in a large area. Background technique [0002] Existing ordinary ceiling fans have narrow blowing surfaces and uneven effects, especially classrooms, auditoriums and other spaces are confined spaces with many people and poor air mobility, resulting in poor air quality. Many students have no wind, which will affect the teaching efficiency of teachers and the classroom experience of students to a certain extent; therefore, it is urgent to develop a ceiling fan with a wide range of blowing on the basis of the existing ceiling fans. [0003] The patent "speed of ceiling fan motor and forward and reverse switch structure" (notification number: CN203560128U) disclosed in the prior art improves the positive and negative rotation of the ceiling fan and the adjustment of wind force, and does not involve expa...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a ceiling fan and method for blowing in a large area, so as to solve the problem that the blowing area of ​​a ceiling fan in a large space such as a classroom cannot be evenly and completely covered by the wind force
