Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description will be made in detail with reference to the accompanying drawings.

As shown in fig. 1, the humidifier of the present invention includes a casing 1, a circuit board 2 for controlling electrical appliances is disposed in the casing 1, and a display 21 and a light source 22 are disposed on the circuit board 2. Accordingly, the housing 1 is provided with a display window through which the display 21 is viewed, and an illumination hole through which the light source 22 leaks. The display 21 is used for displaying the operation information of the display 21, and the light source 22 includes a water tank lamp for illuminating the water tank in the housing 1, an atmosphere lamp for illuminating the inner wall of the housing 1, and the like, so that the humidifier is more beautiful.

As shown in fig. 2, in order to prevent the display 21 from being obscured by the light source 22, a sealing member is provided in the housing 1, and the sealing member includes a light shielding cover 3 sandwiched between the housing 1 and the circuit board 2. The light-shielding cover 3 is formed with a passage 31, one end of the passage 31 is covered on the display 21, and the other end is connected with the observation window of the housing 1. The light-shielding lid 3 thus shields the light source 22 outside the light-shielding lid 3 from the influence and allows the display 21 to be viewed through the passage 31.

Referring to fig. 3, in order to fix the sealing element, two sides of the light shielding cover 3 are provided with fasteners 32, and the circuit board 2 is provided with a bayonet 23 for the fasteners 32 to be fastened, so as to fix the sealing element. And the light shield 3 is formed with the reference column 33, and circuit board 2 is opened has the spacing hole that supplies reference column 33 to run through to play spacing and guide joint's effect.

The positioning flange 11 on the inner wall of the shell 1 and one end of the channel 31 are sleeved on the positioning flange 11, so that the shell 1 and the light shield 3 are fixed.

The light shield 3 is arranged at one side close to the observation window and along the inner wall of the shell 1 so as to be attached to the inner wall of the shell 1. And a seal ring 4 is held between the light shield 3 and the housing 1. In order to fix the sealing ring 4, the light shield 3 is provided with a mounting groove 34 for the sealing ring 4 to be embedded.

The circuit board 2 is provided with a touch spring connected to the touch screen, and the side surface of the light shield 3 is provided with a sleeve 5 sleeved outside the touch spring to prevent the touch spring from dislocation.
