Miniature blower based on etching circuit and control method

Abstract

The invention discloses a miniature blower based on an etching circuit and a control method, the miniature blower comprises a main shell, one end of the main shell is provided with an air outlet, the outer wall of the air outlet is slidably sleeved with an air guide cover, and the outer wall of the main shell is rotatably connected with a plurality of wedge-shaped blocks which are symmetrically arranged through a rotating shaft; wedge-shaped grooves corresponding to the wedge-shaped blocks are formed in the inner wall of the wind scooper; the method includes the following steps that firstly, a rotary knob is rotated to drive a rotary rod to rotate, and the angle of a grip is adjusted; 2, the outer wall of the main shell is sleeved with a wind scooper according to needs, and the wind scooper is fixed; and 3, a control instruction is input through the touch screen, and air blowing operation is carried out. Through the arrangement of the adjusting mechanism, the air guiding mechanism and the filtering mechanism, the hair drier can be freely adjusted according to actual use requirements, meanwhile, air can be filtered, and therefore the use effect of the hair drier is improved.

Description

technical field [0001] The invention relates to the technical field of hair dryers, in particular to a micro hair dryer based on an etching circuit and a control method. Background technique [0002] The hair dryer is a combination of a set of heating wires and a high-speed small fan. When energized, the heating wire will generate heat, and the wind blown by the fan will become hot air after passing through the heating wire. If only the small fan rotates, but the heating wire is not hot, then what is blown out is only wind but not heat. [0003] The heating sheet is a sheet-shaped electric heating element that generates heat. The heating sheet utilizes the good insulation performance and high temperature resistance of the mica board (mica sheet). It uses the mica board (sheet) as the skeleton and insulation layer, supplemented by galvanized sheet or stainless steel sheet for support and protection, and can be made into a plate, Various sheet-shaped heating devices such as...
