[0022] Specifically, the shell 100 is recessed downward toward the inner cavity at the top to form a mounting frame 110. The inner cavity of the mounting frame 110 is a heating cavity 111, which is used to contain water and perform heating and atomization. A heating channel 112 is provided at the bottom of the mounting frame 110. In this embodiment, the bottom of the mounting frame 110 has two heating channels 112, one of which is used to install the heating element 200, and the other heating channel 112 is provided with an atomizing sheet to atomize the water in the atomizing strengthening cavity to form a humidified water mist; a plurality of fixing holes 210 are provided on the edge of the heating element 200, and the heat insulating member 300 is inserted through the fixing holes 210 and then fixedly connected to the bottom of the mounting frame 110 by threads, so that the heating element 200 is fixed to the bottom of the mounting frame 110, and the main body of the heating element 200 is the heating portion 220, and the heating portion 220 extends Into the heating channel 112, a sealing ring 500 is embedded between the two to form a sealed connection and separate the heating element 200 from the mounting frame 110; the sealing ring 500 and the thermal insulation member 300 are both made of high temperature resistant materials; the heat of the heating element 200 is isolated by the sealing ring 500 and the thermal insulation member 300, and the heat will not be conducted to the mounting frame 110 to cause hot melting, and the thermal insulation structure is simple and efficient, and easy to install; in addition, the thermal insulation frame 400 is adapted to the shape of the mounting frame 110, and the thermal insulation frame 400 is surrounded by the outside of the mounting frame 110. When the heating element 200 heats the water in the heating chamber 111, under the thermal insulation effect of the thermal insulation frame 400, the high temperature is not easily conducted to other parts of the shell 100, ensuring that the electrical components or other components of the humidifier are not easily affected.

[0023] Furthermore, a plurality of fixing columns 113 extend from the bottom of the mounting frame 110; a mounting wall 230 extends horizontally from the bottom of the heating element 200, and a plurality of fixing holes 210 are formed in the mounting wall 230, and the heat insulating member 300 passes through the fixing holes 210 and is threadedly connected to the fixing columns 113. The heat insulating member 300 is T-shaped, and a plurality of limiting ribs 310 are provided on the side wall, and the limiting ribs 310 abut against the inner wall of the fixing hole 210.

The other end of the heat insulating member 300 abuts against the fixing column 113. With the setting of the limiting rib 310, the direct contact area with the heating element 200 is reduced, and the heat conduction is further reduced.

The upper end surface formed abuts against the bottom surface of the limiting wall 1121, and the height of the abutting portion 510 is greater than that of the upper and lower ends. At the height from the limiting wall 1121 to the bottom of the heating channel 112, there is a spacing L between the mounting wall 230 of the heating element 200 and the bottom of the mounting frame 110, and the heat will not be directly conducted to the mounting frame 110; the mounting groove formed by the mounting wall 230 abuts against the lower end of the abutting portion 510, and the shapes are adapted; the sealing ring 500 can be made of high-temperature resistant silicone material, while isolating the heat conduction, through the cooperation with the limiting wall 1121, the sealing effect is good.

The circuit board 600 is fixed to one side of the insulation frame 400. Under the insulation effect of the insulation frame 400, the circuit board 600 is not easily affected by the high temperature in the heating chamber 111, thereby ensuring the normal operation of the humidifier. In this embodiment, it has multiple insulation structures to ensure that when the heating element 200 is working, the surrounding components are not easily affected by the high temperature and caused damage, and the overall structure is simple, which is convenient for production and manufacturing.
