Then, each group of ultraviolet germicidal lamp tubes is started, so that the ultraviolet rays emitted when the ultraviolet germicidal lamp tubes start to work can irradiate on the fixed frame, so that the mites and bacteria on the fixed frame can be effectively killed under the long-term irradiation of the ultraviolet rays, thereby realizing the antibacterial and anti-mite of the rotary magnetic massage bed, so as to reduce the probability of mites and bacteria breeding on the mattress and causing harm to the physical health of the user.

[0017] Through the arrangement of the rotating shaft, the flapping plate and the first stepping motor, when the first stepping motor starts to work, it can drive the two worm gears to rotate periodically forward and backward. When the two worm gears rotate, they can respectively drive the two worm wheels and the two rotating shafts to rotate accordingly. When the rotating shafts rotate, they can flap the mattress, so as to discharge the dust and mite dust adhered to the mattress, thereby realizing the effective cleaning of the mattress.

[0018] Through the settings of the brush plate, the flapping plate and the second stepping motor, when the second stepping motor starts to work, it can drive the flapping plate to rotate. When the flapping plate rotates, it can drive the brush plate to slide along the guide rod, so as to brush the surface of the transparent glass tube, thereby reducing the probability that dust falls on the transparent glass tube and affects the ultraviolet rays emitted when the ultraviolet germicidal lamp tube works from passing through the transparent glass tube.
