[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model, after the switch is turned on, the power supply drives the motor to rotate, and the output shaft of the motor drives the water pump to rotate through the transmission. The water pump draws water from the water tank through the water pump pipe, and brings the water in the water tank to the water rail above. The bracket is located under the water rail, which plays the role of fixing and supporting the water rail. There are many small water outlet holes distributed in the water rail. Under the high pressure of the water pump, water is sprayed from the water outlet holes to form a fine water mist that is sprayed onto the heating wire mesh below the water rail. The heating wire mesh starts to heat up when power is supplied, and the water mist sprayed on it is vaporized into water vapor and discharged from the exhaust hole above and emitted into the air, thereby humidifying the air.

The thermostat is composed of two metals with different expansion coefficients. When the temperature is lower than ℃, they are in a fitted state. When the temperature is higher than ℃, the two metal strips will deform and disconnect, immediately blocking the power supply and continuing heating, ensuring that the temperature does not exceed a certain value. The liquid level sensor is a sensor for detecting the water level in the water tank. It is connected to the liquid level probe at the bottom of the water tank. When the water in the water tank is lower than the liquid level probe, the water level signal light on the liquid level sensor will flash to remind you that the water level is insufficient.

[0015] 3. The utility model uses an insulating ring as a high-temperature resistant insulating material, which is located between the heating screen and the shell to fix and support the heating screen and the isolation shell. The raised block is located at the bottom of the humidifier body, and the buckle is located at the top of the water tank. The two are connected at the top. When the raised block moves longitudinally and then horizontally, it is stuck in the circular part at the tail end of the buckle, so that the humidifier body and the water tank are combined. The water level scale is transparent, which is convenient for observing the water level. BRIEF DESCRIPTION OF THE DRAWINGS
