Abstract:
An electrical protection structure of a detachable electric appliance and a gas treatment device. The electrical protection structure of the detachable electric appliance implements electrical protection when the electric appliance is in a disassembled state; the electrical protection structure comprises a switch (1); the switch (1) comprises an elastic piece (11) and a base (15); a movable contact (111) is provided on the elastic piece (11); a static contact (151) is provided on the base (15); the switch (1) is connected in series with a circuit inside the electric appliance; the electrical protection structure comprises a detachable member (2) provided on the electric appliance; a pressing part (21) is provided on the detachable member (2); when the detachable member (2) is in an installed state, the pressing part (21) presses the elastic piece (11), the movable contact (111) abuts against the static contact (151), and the switch (1) is in an on state; and when the detachable member (2) is in the disassembled state, the pressing part (21) leaves the elastic piece (11), the movable contact (111) leaves the static contact (151), and the switch (1) is in an off state. According to the electrical protection structure of the detachable electric appliance and the gas treatment device, when the detachable member (2) is in the disassembled state, the switch (1) closes the circuit inside the electric appliance, thereby avoiding a safety accident, and improving the safety of the electrical protection structure of the detachable electric appliance and the gas treatment device.
