Multi-direction induction fan

Abstract

The invention discloses a multi-direction induction fan. The multi-direction induction fan is composed of a shell, an operation button, air ducts, an impeller, a motor, an air door, an infrared sensor, a distance sensor and a microcomputer module, wherein the shell is cylindrical; the operation button is mounted on the outer side of the shell; the microcomputer module is mounted at the bottom of the shell; an air inlet is formed in the upper part of the shell; air outlets are distributed around the shell; the air ducts are composed of one air inlet duct and a plurality of air outlet ducts; oneend of the air inlet duct is connected to the air inlet of the shell; the other end of the air inlet duct is connected with one ends of the air outlet ducts; a rotating shaft of the motor is downwards mounted in the air inlet duct; the impeller is mounted on the rotating shaft of the motor; the other ends of the air outlet ducts radially stretch to the position around the inner side of the shell;the air door is arranged on openings of the air outlet ducts; and the infrared sensor and the distance sensor are arranged on the outer side of the position, at the air door, of the shell. The multi-direction induction fan has the beneficial effects that the air blowing direction can be confirmed through body induction, and air can be blown to the directions requiring air blowing at the same time.

Description

technical field [0001] A multi-directional induction fan. Background technique [0002] Although the existing electric fan can blow air in different directions by swinging back and forth, it can only blow air in one direction at the same time, and it cannot only blow air in the direction of people, which is not smart enough. Simultaneously, because of its limited range of swing, if there are people in all directions around it, some people will not be able to blow the wind, and the effect of blowing wind in all directions cannot be achieved. Contents of the invention [0003] In order to overcome the shortcomings of the existing electric fans, the invention provides a multi-directional induction fan. Through the operation button of the multi-directional induction fan, the wind force of blowing through each air outlet can be set. The microcomputer module obtains that the infrared intensity fed back by the infrared sensor at a certain place is greater than the set value, and...
