Wall fan gear automatic switching mechanism

Abstract

The invention relates to a wall fan gear automatic switching mechanism which comprises an alternating-current and direct-current dual-purpose motor arranged in a control box of a wall fan and used forproviding power for driving of the wall fan, and the alternating-current and direct-current dual-purpose motor is a series excitation type motor or a parallel excitation type motor. The DDR storage device is arranged in a control box of the wall fan and used for storing a personnel gear table, and the personnel gear table takes the personnel number as an index and stores the mapping relation between the personnel number corresponding to the common personnel using the wall fan and the corresponding conventional gear; the feature recognition equipment is used for analyzing the facial features in the target pattern, and determining a corresponding personnel number based on the obtained facial features to serve as a reference personnel number to be output; and the gear selection equipment isused for searching the conventional gear corresponding to the reference personnel number in the personnel gear table and switching the current gear of the wall fan based on the conventional gear. According to the invention, the current gear of the wall fan equipment can be flexibly controlled.

Description

technical field [0001] The invention relates to the field of wall fan equipment, in particular to a mechanism for automatically switching gear positions of a wall fan. Background technique [0002] Wall fan refers to a small electric fan installed on the wall to save space. It is characterized by convenience, practicality and beauty. Wall fans are divided into two types: directional wall fans and steering wall fans. The steering wall fans can swing their heads to blow air, with a wide range of blowing and strong wind. Wall fans are mostly used in canteens, restaurants, factories and other places. Contents of the invention [0003] In order to solve the technical problem in the prior art that the position of the wall fan cannot automatically adapt to the customary needs of various target personnel, the present invention provides an automatic switching mechanism for the position of the wall fan, which analyzes the vertical and horizontal data of the image to obtain Each r...
