Description

technical field [0001] The invention relates to the field of small household appliances, in particular to an ultrasonic humidifier. Background technique [0002] The human body has certain requirements for the air humidity. When it is hot or cold, people will turn on the air conditioner to adjust the temperature, and turning on the air conditioner in the room for a long time will make the air in the room dry, and the human body feels extremely uncomfortable. In order to increase the humidity in a dry room, people often use a humidifier to add moisture to the air. Common humidifiers include ultrasonic humidifiers. The working principle of ultrasonic humidifiers is to use the principle of ultrasonic high-frequency oscillation to atomize water into ultrafine particles of 1 to 5 microns, and diffuse the water mist into the air through a pneumatic device, thereby achieving The purpose of evenly humidifying the air. [0003] Existing humidifiers are generally composed of a water...

AI Technical Summary

Problems solved by technology

[0003] Existing humidifiers generally consist of a water tank and a base. The water tank is installed on the base. There is no connecting structure between the water tank and the base. It is easy to cause the humidifier to be overturned when moving the water tank.

Moreover, in order to prevent dry burning, most humidifiers are equipped with a water shortage protection circuit. The water shortage detection method is generally a dry reed switch with a floating magnetic ring detection method, or a water surface probe detection method, and its circuit structure is relatively complicated.
