Background

A humidifier is a home appliance that increases the humidity of a room. There are two common ways of humidifying a humidifier. One is ultrasonic atomization, which atomizes and outputs water by high-frequency oscillation of an ultrasonic atomization sheet; the other is thermal evaporation type atomization, in which water is heated to 100 ℃ in a heating body to generate steam, thereby outputting water vapor.

In order to achieve a preferable atomization and humidification effect, the humidifier for atomizing by using the ultrasonic atomization sheet needs to heat tap water to about 50 degrees and then atomize the tap water. In the existing humidifier, an atomizing water tank and a heating water tank are arranged on a base, and water in a water tank is heated by the heating water tank and then conveyed to the atomizing water tank for atomization. The ultrasonic atomization structure is complex.

In addition, the ultrasonic atomization humidification atomization effect is uniform, but the ultrasonic atomization humidification atomization device needs to work at normal temperature or in warm water, the output water mist temperature is close to the room temperature, and the use effect is poor in a colder environment; the thermal evaporation type atomization device has a simple structure and high energy consumption, can output high-temperature water mist, can raise the temperature of the environment, and can be used in colder environments. The existing atomizer has single working mode, and is difficult to meet the use requirements of various environments, so that further improvement is sought.
