[0038] Working Principle: During operation, first install two electrical connectors 9 on the base 8 during installation. A circuit storage cavity is formed inside the base 8. Electrical equipment such as wires are placed inside the circuit storage cavity. PCB board 6 is installed on the bottom of the panel 5. Film 4 is installed on the top of the panel 5. The panel 5 and PCB board 6 are fixed together with screws. The buzzer 1, button 2 and dimmer 3 are installed on the panel 5 in sequence. Finally, the panel 5 and base 8 are combined, and a sealing gasket 7 is installed between the panel 5 and the base 8. The sealing gasket 7 is used to waterproof the interior of the circuit storage cavity.

[0039] When installing the panel 5, the sealing gasket 7 and the base 8, align the corresponding positioning holes 10 on the three, and then insert the insertion rod 1201 from the positioning hole 10 on the panel 5 and pass through the three positioning holes 10 in sequence until the end baffle 1202 is in close contact with the surface of the panel 5, and then put the end limit unit 1204 on the other end of the insertion rod 1201. The end limit unit 1204 is located below the base 8. During installation, push the two push plates 12058 close to each other, so that the two first movable plates 12054 are mutually Close the clamping rod 12055 until it enters the first rod groove 12052. After the end tube 12041 is installed at the end of the insertion rod 1201, the push plate 12058 is released. The push plate 12058 moves back under the elastic force of the first spring 12059, causing the clamping rod 12055 to move outward and fit into the clamping groove 12042, so that the insertion rod 1201 and the end tube 12041 are clamped and fixed. Then, the nut 12043 is tightened so that the panel 5 and the base 8 press the sealing gasket 7 tightly, thereby improving the waterproof sealing effect.

[0040] When the humidity of the external environment is high, the humidity sensor 120615 senses the humidity. When the humidity is high, the controller 120616 controls the electromagnet 120614 to energize, generating a repulsive force on the magnetic block 12063, and then generating pressure on the movable plate 12062 toward the side of the end baffle 1202, and then through the first rack 12065, the gear 12066 and the second rack 12068, a pulling force is generated on the cross bar 12069 toward the side of the end baffle 1202, thereby generating a pulling force toward the side of the end baffle 1202 on the first movable plate 12054 through the end block 120610 and the side rod 120613, thereby increasing the clamping force between the panel 5 and the base 8, improving the sealing effect between the panel 5 and the base 8 and the sealing gasket 7, and improving the waterproof effect.
