Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, the ...

Abstract

The invention discloses a detection circuit and a detection method thereof, a fan and a readable storage medium. The detection circuit is used for detecting a boundary position in a fan head shaking process, and the detection circuit comprises a controller, a power supply circuit, a stepping motor, a winding switch and a sampling resistor; the control end of the winding switch is connected with the controller, the input end of the winding switch is connected with the power supply circuit through a winding of the stepping motor, and the output end of the winding switch is grounded through the sampling resistor; the power supply circuit comprises a change-over switch, a first power supply access and a second power supply access, the first power supply access and the second power supply access are connected in parallel, the change-over switch is used for switching one of the first power supply access and the second power supply access to be switched on, and the current when the first power supply access is switched on is larger than that when the second power supply access is switched on. And the change-over switch is connected with the controller. The method has the advantage of simplifying the detection circuit and structure of the fan head shaking boundary position.

Description

technical field [0001] The invention belongs to the technical field of fans, and in particular relates to a detection circuit and a detection method thereof, a fan and a readable storage medium. Background technique [0002] In the prior art, the fan oscillating mechanism needs to realize 30, 60, 90, 120 degrees and other different angle ranges of oscillating the head, and a positioning system composed of a Hall sensor, a magnet, a stepping motor, and a controller is required. The Hall sensor is usually set in the middle position, and there is also a magnet in the shaking head mechanism. During the rotation of the shaking head mechanism, when the magnet passes the Hall sensor, the Hall sensor senses the signal, so it is determined that the shaking head mechanism is in the middle of the shaking head path. Position, then control the shaking head mechanism to shake the head left or right, the control circuit and structure in the prior art are more complicated. Contents of the...
