Problems solved by technology

[0003] The above-mentioned fan head angle adjustment structure has the following disadvantages: Since the contact surface between the insert piece and the clamp piece is flat, it is difficult to ensure that the clamp piece clamps the insert piece only by the cooperation of the nut and the bolt. The fan head suddenly changes from the state of flat blowing or upward blowing to the state of downward blowing
[0004] In addition, the fan head of the traditional floor fan can swing left and right. The swing structure is a set

Abstract

The purpose of the present invention is to propose a fan head angle adjustment structure, which can easily adjust the fan head pitch angle and rotation angle, and reliably fix the fan head at a predetermined pitch angle, so as to satisfy users demand. The angle adjustment structure of the fan head of the present invention can make the pitch angle of the fan head better fixed and can be easily adjusted by adding an intermediate piece and making slight changes on the traditional clamping piece and inserting piece. The pitch angle of the fan head; at the same time, the present invention detects the rotation angle of the fan head in real time through a stepping motor, and compares the rotation angle with the input target angle value, thereby controlling the fan head to reverse when the fan head rotates to the limit angle. To rotate, to achieve the purpose of reciprocating rotation of the fan head within a predetermined angle range. To sum up, the present invention simultaneously realizes the adjustment of the pitch angle and the rotation angle of the fan head, and has good practicability.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a fan head angle adjustment structure. Background technique [0002] The fan head of the traditional floor-standing fan is simply adjusted by bolts to adjust its pitch angle. The specific structure is as follows: the top of the bracket is provided with two vertical clamping pieces, and the insert piece at the bottom of the fan head is inserted into the two clamping pieces. Then use bolts to pass through the first clamping piece, the inserting piece, and the second clamping piece in turn, and screw the nut on the other end. By adjusting the position of the nut, the clamping piece is loosened or clamped and inserted. When released, the pitch angle of the fan head can be adjusted. [0003] The above-mentioned fan head angle adjustment structure has the following drawbacks: because the contact surface between the insert piece and the clamping piece is flat, it is difficult ...
