Air purifier with functions of automatically cleaning and displaying negative ion release concentration

Abstract

The invention relates to an air purifier with functions of automatically cleaning and displaying negative ion release concentration. The air purifier is characterized in that an automatic cleaning mechanism comprises a drive motor and a cleaning rod, wherein the drive motor and a carbon fiber negative ion release head of a negative ion generator are arranged on the same rack; the cleaning rod is arranged at the output end of the drive motor; after the drive motor is started by a PWM signal of a micro processor, the cleaning rod stirs carbon fibers of the carbon fiber negative ion release head; a display mechanism for the negative ion concentration comprises a negative ion receiving plate, a signal processing circuit and a group of display lamps; the signal received by the negative ion receiving plate is fed into an A / D port of the micro processor after being treated by the signal processing circuit, so that the micro processor drives a corresponding LED indicator lamp; when a drive interval is detected to satisfy set timing time, or when negative ion release concentration detected by the negative ion receiving plate is smaller than 2.5 million / cm<3>, the micro processor emits the PWM signals to drive the drive motor of the cleaning mechanism.

Description

technical field [0001] The invention relates to an air purifier, in particular to an air purifier with automatic cleaning and displaying negative ion release concentration. Background technique [0002] Negative ions are everywhere in nature. Natural phenomena such as thunder and lightning, photosynthesis of plants, and the impact of waterfalls and water can produce a large amount of negative ions. Negative ions in the air, also known as "air vitamins", are an indispensable substance for human health and life just like sunlight and air. Scientific research has shown that the content of negative ions in the air is an important factor determining the quality of the air. An appropriate amount of negative ions in the air can not only effectively remove dust, sterilize, and purify the air, but also activate oxygen molecules in the air to form Carrying negative oxygen ions, the negative ion generator activates air molecules, improves human lung function, promotes metabolism, e...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an air purifier with automatic cleaning and display of negative ion release concentration, aiming at the fact that the current negative ion generator cannot timely determine the cleaning timing of the negative ion release head, and the cleaning can only be done manually.
