An electric fan head tilting angle regulating device

Abstract

The invention relates to an electric oscillating angle regulator, belong to accessories of electric fan, comprising: an angle modulation knob, a dial, an imported angle signal converter, a stretching wire, a baffle plate with cut, and a segmented positioning device between the angle modulation knob and the imported angle signal converter, which has a plurality of segmented positioning modes, and the minimum distance when segmented position is bigger than the return error and idle displacement of the course that oscillating adjusting the angle modulation knob. Said invention avoids the idle operation when operating the angle modulation knob, to form a quick and effective electric oscillating angle regulator, which fit the oscillating fan.

Description

technical field [0001] The invention relates to an electric fan oscillating angle adjusting device, which is especially suitable for manipulating the angle adjustment knob on the panel of the electric fan seat, so that the electric fan can effectively adjust the swing angle. Background technique [0002] In the prior art, in the patented inventions "Electric Fan Swing Angle Adjustment Device" (ZL89100824) and "Electric Fan Swing Angle Adjustment Device" (Application No. 00117492.4), a user preset swing angle value is shown. , the automatic angle adjustment system that automatically completes the angle adjustment by the electric fan itself, referring to the original text, we can see that the angle adjustment system consists of a housing, a worm-worm gear-gear reduction mechanism, a variable-length crank mechanism for a planetary gear system, a ratchet pawl clutch, and a cam- Swing rod sampler, swing rod-push plate pawl control mechanism, angle adjustment button, dial, input a...

[0002] In the prior art, in the patented inventions "Electric Fan Swing Angle Adjustment Device" (ZL89100824) and "Electric Fan Swing Angle Adjustment Device" (Application No. 00117492.4), a user preset swing angle value is shown. , the automatic angle adjustment system that automatically completes the angle adjustment by the electric fan itself, referring to the original text, we can see that the angle adjustment system consists of a housing, a worm-worm gear-gear reduction mechanism, a variable-length crank mechanism for a planetary gear system, a ratchet pawl clutch, and a cam- Swing rod sampler, swing rod-push plate pawl control mechanism, angle adjustment button, dial, input angle signal converter, cable and baffle with notch, but, because the angle adjustment button, input angle signal converter The angle adjustment signal transmission system composed of cables, cables and notched baffles is composed of multiple sets of mechanical structures, and there must be various accumulative gaps and errors in assembly, which will lead to return errors in the reciprocating adjustment of the angle adjustment button in the forward and reverse directions. And invalid displacement stroke, the return error and invalid displacement stroke of this kind of adjustment button, often produce misleading and ineffectiveness in use, when the user twists the adjustment button, the assumed value of angle adjustment is less than or equal to the return error of the angle adjustment button and invalid displacement stroke, the gap of the baffle plate at the end of the angle adjustment signal transmission system cannot produce a corresponding displacement, and the baffle plate cannot block the swing rod. Therefore, the electric fan oscillating mechanism does not produce a corresponding angle adjustment change at all, which leads to this adjustment. The angle operation fails. Obviously, in the process of transmitting the angle adjustment signal by this multi-group mechanical combination, the shortcomings of the angle adjustment failure caused by the return error and invalid displacement stroke of the angle adjustment button need to be improved.
