Abstract

The invention discloses a high-voltage module protection method and device of an air purifier and the air purifier. The method comprises the steps of obtaining feedback voltage of a voltage doubling module of a high-voltage module; when the feedback voltage is continuously lower than a preset reference value within preset time, determining that the high-voltage module is broken down; and reducing output voltage of the high-voltage module to a first high-voltage value on the basis of the fault if the output voltage of the high-voltage module is greater than a preset first high-voltage value when the high-voltage module is located in a voltage mode conversion process. According to the scheme, the defects of high misoperation rate, low reliability, poor user experience and the like in the prior art can be overcome; and the beneficial effects of low misoperation rate, high reliability and good user experience are achieved.

Description

technical field [0001] The invention belongs to the technical field of air purifiers, and in particular relates to a high-voltage module protection method and device of an air purifier and an air purifier, in particular to a method and device for judging and processing ignition protection of a high-voltage module of an air purifier And an air purifier with the device. Background technique [0002] The air purifier can absorb, decompose or transform various air pollutants (such as: PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), effectively improving the air cleanliness. In order to solve the problem of breakdown between the high-voltage electrodes (such as: high-voltage positive electrode and high-voltage negative electrode) of the air purifier in a high-humidity environment, and the problem of creepage between the high-voltage electrode and nearby materials in a high-humidity environment, usually Such technical problems are...
