specific Embodiment 1

[0030] A switch with explosion-proof function for household appliances, the switch with explosion-proof function is a door light switch and a switch part in a thermostat. The switch 10 with explosion-proof function is composed of a button 15 , a switch box body 11 with a circuit opening and closing device inside, contact pins 14 connected to the circuit, a soft rubber cover 13 and a casing 12 . The soft rubber cover 13 is set on the switch box body 11 and forms a cavity 16 for accommodating buttons with the box body 11 , and the opening of the box body corresponding to the button is located in the cavity 16 . The shell 12 is nested on the soft rubber sleeve 13 that is in contact with the switch box body, and the soft rubber sleeve 13 is tightly connected with the switch box body 11, that is, the gap 21 between the soft rubber sleeve 13 and the switch box body 11 is sealed with glue. . The sealed connection between the contact pin 14 and the switch box body 11 is to inject glu...

specific Embodiment 2

[0034] Since the door light switch is frequently used, and the door often has a greater impact force when it is closed, this may cause the above-mentioned soft rubber cover of the switch with explosion-proof function to be aged and damaged. Therefore, the present invention also provides another explosion-proof function. Switch the door light switch. The switch with explosion-proof function is a clarinet switch 30, which is composed of a clarinet body 31 and contact pins 32 connected to the circuit. The clarinet body 31 is a closed body. The gas in the clarinet body 31 is helium or nitrogen, which can ensure the normal operation of the explosion-proof switch and prolong the service life of the switch. The contact pin 32 of the connecting circuit is a needle-like pin, and the needle-like pin is plugged in the jack connecting the door light circuit. This design can facilitate the installation and disassembly of the explosion-proof switch, and is easy to maintain and replace.

Abstract

The invention relates to an explosion-proof function switch, which belongs to the gate lamp switch as well as the switching element of the thermostat. It is composed of key-press, switch box body which contains the circuit switching installment, touch foot which connects the circuit and soft gum cover and the outer covering, the soft gum cover covers on the switch-box body and with the box body forms the cavity hold the key-press, the box body corresponds the aperture of the key-press located in the cavity, the outer covering nests on the soft gum cover which contacts the switch-box body, the soft gum cover hermetic connects the switch-box body, the touch foot hermetic connects the switch-box body, the air in the cavity and the switch-box body inner space is isolated with the air in the switch-box body exterior space. The explosion-proof function switch also can be the clarinet switch which is composed of the clarinet body and the touch foot of junction circuit. The explosion-proof function switch has low cost and easy to install and maintenance.

Description

technical field [0001] The invention relates to a switch with explosion-proof function for household appliances. Background technique [0002] Existing switches of this type do not have an explosion-proof function, mainly because the sealing of the switch is not good, and gas easily enters the inside, so that explosion-proof cannot be achieved. [0003] Comparative document 1, patent No. 01217314.2 discloses a kind of explosion-proof switch in the Chinese patent document, as shown in Figure 1, it comprises an insulating shell 11' and the control circuit board 12' installed in the insulating shell, and the circuit board passes through The wire 13' is connected to the plug 14'. The flame retardant epoxy resin material can be potted between the shell and the control circuit board, and after vacuum treatment, it is cured and formed. The circuit board is connected to the plug through the lead wire, and the joint can be sealed with silicone rubber 15'. The utility model is not o...
