Problems solved by technology

[0003] The driving circuit of the traditional ultrasonic nebulizer can only be used to drive the ultrasonic atomizing sheet to atomize the water, and cannot detect the water level; however, the water level of the nebulizer is different, and the fogging effect varies greatly. When the water level is high, the driving power of the atomizer can be adjusted according to the real-time water level, thereby adjusting the fogging effect of the atomizer. Therefore, how to detect the water level of the atomizer is particularly important.

Abstract

The invention discloses a water level detecting method for an atomizer. The water level detecting method comprises the following steps that S1, an ultrasonic oscillation module sends out a current ultrasonic signal; S2, the current ultrasonic signal is reflected by the water surface to form an echo signal, an ultrasonic receiving module receives the echo signal and sends out a current voltage signal according to the echo signal; S3, a microcontroller receives the current voltage signal and calculates current water level height according to the sending time of the current ultrasonic signal andthe receiving time of the current voltage signal. The invention also discloses a water level detecting device of the atomizer. By adopting the method and the device, the water level height can be accurately and quickly detected.

Description

technical field [0001] The invention relates to a water level detection method and device for an atomizer. Background technique [0002] In order to increase the humidity in a dry room, people often use a humidifier to add moisture to the air. As a relatively mature humidification product, the ultrasonic humidifier has won the favor of consumers. The working principle of the ultrasonic humidifier is to use the principle of ultrasonic high-frequency oscillation to atomize water into ultrafine particles of 1 to 5 microns. Diffuse the water mist into the air, so as to achieve the purpose of evenly humidifying the air, make the air moist and accompanied by rich negative oxygen ions, achieve uniform humidity, freshen the air, improve health, change the hot and dry winter heating, and create a comfortable home environment . [0003] The driving circuit of the traditional ultrasonic nebulizer can only be used to drive the ultrasonic atomizing sheet to atomize the water, and canno...
