Problems solved by technology

However, the electrical signal sampling device composed of the slider contact—the contact piece is a sliding friction contact device. Over time, it will cause wear and corrosion, which will cause disorder in the sampling electrical signal, resulting in angle adjustment of the main control circuit board. The chip operation failed, which needs to be improved

Embodiment Construction

[0012] The present invention will be further described below with embodiment and accompanying drawing:

[0013] refer to figure 1 and figure 2 , the present invention comprises the angle-adjusting gear box 6 that is equipped with planetary gear crank 7 mechanisms, magnetic attraction device 1, is made up of cam (not shown)-follower 3-swing bar 2 mechanical sampling device, main control circuit plate 9 and signal line 8, and a permanent magnet 5 is placed at the action end 4 of the pendulum bar 2 of the mechanical sampling device. The corresponding up and down displacement causes the permanent magnet 5 provided at the action end 4 of the pendulum rod 2 to also interlock to make an up and down displacement corresponding to the variable-length rotation track of the planetary crank 7, so that the permanent magnet 5 becomes an uncharged crank position indicator Hall sensor 11, Hall sensor 12 and Hall sensor 13 are placed in the corresponding gap of permanent magnet 5, and Hall s...

Abstract

An electric fan angle modulation sampling device comprises an angle modulation gearbox provided with a planetary wheel crank mechanism, a magnetic attraction device, a mechanical sampling device, a master control circuit board and a signal line. The electric fan angle modulation sampling device is characterized in that an uncharged crank position marker is disposed between the mechanical samplingdevice and the signal line, a semiconductor sensor is disposed in a gap corresponding to the uncharged crank position marker, the semiconductor sensor is connected with the master control circuit board through the signal line, and thus a set of non-contact electric fan angle modulation sampling device without contacts or contact pieces is formed.

Description

technical field [0001] The invention relates to an electric fan, in particular to an electric fan angle adjustment sampling device. Background technique [0002] An existing electric fan sampling device (such as patent No. 201010507526.0) technology is characterized in that a cam-follower-swing rod mechanical sampling device is arranged in an angle-adjusting gear box with a planetary crank mechanism, and the cam- —Follower——The swing rod action end of the swing rod mechanical sampling device is equipped with a set of electrical signal sampling device composed of slider contacts-contact pieces. The electrical signal sampling device is connected to the main control circuit board through the signal line, and the The sampling electrical signal is fed back to the main control circuit board to control the magnetic attraction device to engage and disengage, and to control the variable-length rotation action and adjustment of the planetary crank, thereby completing the electrical si...
