Document Type and Number:
WIPO Patent Application WO/2020/042475
Kind Code:
A1
Abstract:
An electrical protection structure for a removable electronic appliance and a gas processing device. The electrical protection structure for a removable electronic appliance achieves electrical protection when the electronic appliance is in a removed state, wherein the electrical protection structure comprises a proximity switch (1), and the proximity switch (1) is connected in series to a circuit inside of the electronic appliance; the proximity switch (1) comprises a magnetic control element, and the electrical protection structure comprises a removable piece (2) that is disposed on the electronic appliance, the removable piece (2) being provided thereon with a magnetic element (4); when the removable piece (2) is in an installed state, the magnetic element (4) is close to the magnetic control element such that the proximity switch (1) is in an on state; when the removable piece (2) is in a removed state, the magnetic element (4) is far from the magnetic control element such that the proximity switch (1) is in an off state. Regarding the electrical protection structure for a removable electronic appliance and the gas processing device, when the removable piece (2) is in a removed state, the proximity switch (1) turns off the circuit inside of the electronic appliance, thereby preventing safety accidents and improving the safety of the electrical protection structure for a removable electronic appliance and the gas processing device.
