Household switch having safety protection function

Abstract

The invention relates to the field of household electrical appliance equipment, in particular to a household switch having a safety protection function. The household switch comprises an installationbox, a panel, a switch part and a socket part, wherein the switch part comprises a switch key, the panel can be buckled onto the installation box, a jack is arranged in the panel, sliding grooves areformed in inner walls of two sides of the installation box, a support rod is connected to the sliding grooves in a sliding way, the switch key can be pushed to rotate by the support rod, an air bag isarranged at one end of each sliding groove and can push the support rod to slide towards the installation box, an external thread is arranged at one end, far away from the air bag, of the support rod, a rotatable impeller is arranged at one end, far away from the air bag, of the installation box, a central hole is formed in a center of the impeller and can be used for the support rod to penetratethrough, an internal thread is arranged in the central hole and is matched with the external thread in a rotation direction, cooling holes are formed in a side wall, far away from the air bag, of theinstallation box and are hinged with a shielding plate capable of rotating outwards, a push rod is connected to an outer wall of the installation box in a sliding way, the push rod is arranged opposite to the jack, and the push rod can be driven to move upwards by the shielding plate.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a household switch with safety protection function. Background technique [0002] As an electronic component that can open a circuit, interrupt current, or flow to other circuits, a switch has one or several electronic contacts. "Closed" of the switch means that the electronic contacts are conducting, allowing current to flow; "open circuit" of the switch means that the electronic contacts are not conducting to form an open circuit, and current is not allowed to flow. For example, when the switch of the socket is in the closed state, the socket part is energized, and the electrical appliances connected to the socket part can be used normally. When the switch part of the socket switch is in the open state, the socket part is powered off. In this case, Even if the electrical appliance connected to the socket is turned on, the electrical appliance cannot be used at this time bec...

AI Technical Summary

Problems solved by technology

For example, when the switch of the socket is in the closed state, the socket part is energized, and the electrical appliances connected to the socket part can be used normally. When the switch part of the socket switch is in the open state, the socket part is powered off. In this case, Even if the electrical appliance connected to the socket is turned on, the electrical appliance cannot be used at this time because the power supply socket is in a power-off state.

[0003] Electricity, as an energy source that is closely related to the operation of electrical equipment, not only benefits mankind, but also has many potential safety hazards.

For example, when the socket switch is in use, the common problem is that the socket switch is overloaded with electricity, causing the socket switch to heat up, resulting in damage to the socket switch, and even causing a fire.
