9. A method of using an electrical fire hazard online monitoring alarm device, using an electrical fire hazard online monitoring alarm device as claimed in any one of claims 1 to 8, characterized in that, The method comprises the following steps: When the device is in normal use, the infrared monitoring camera (208) can monitor the change of temperature, and the smoke monitoring sensor (205) can monitor the smoke generated by fire in the air, when the temperature rises or the concentration of smoke rises due to fire, the infrared monitoring camera (208) or the smoke monitoring sensor (205) will send out a fire alarm to the outside, at the same time, the loudspeaker (206) will send out an alarm and the ring-shaped warning light (207) will emit light to show warning. In order to remove dust attached to the surface of the device, the driving motor (3101) will be started at regular intervals, which will drive the connecting bracket (3105) and the cleaning assembly (32) to rotate together, and the soft brush (32053) and the hard brush (32086) in the cleaning assembly (32) will remove the dust on the surface of the dust filter net (203) when rotating; After the connecting bracket (3105) rotates for a certain number of turns, the connecting sleeve (3207) and the chain type brush (3205) connected thereto move downward, so that the chain type brush (3205) moves from the vertical guide groove (3202) to the arc-shaped guide groove (3204), and at this time the bristles of the soft brush (32053) are attached to the spherical surface of the infrared monitoring camera (208); Then the connecting bracket (3105) still rotates, driving the chain type brush (3205) to clean the dust on the surface of the infrared monitoring camera (208), and the chain type brush (3205) will move upward after rotating for a certain number of turns. Reset, and then turn off the driving motor (3101); When the chain type brush (3205) cleans the dust filter net (203) downward, the bristles of the soft brush (32053) abut against the blocking bracket (408) and then deform, and the bristles rebound after passing through the blocking bracket (408), thereby shaking off the dust attached to the soft brush (32053), achieving the effect of cleaning the soft brush (32053).
