Description

Three-in-one wireless microphone device for teaching Technical Field The utility model relates to the technical field of wireless microphone devices, in particular to a three-in-one wireless microphone device for teaching. Background The three-in-one digital wireless microphone is a latest audio-visual education product. The product adopts pen-shaped design, and is automatically frequency-matched, and the lithium battery is supplied with power for a long time. When the existing three-in-one wireless microphone device for teaching is not used, most of the three-in-one wireless microphone device is directly exposed in the air, impurity dust in the air can be attached to the side wall of the wireless microphone, and if the dust enters the wireless microphone, the wireless microphone can be damaged. Therefore, the utility model provides a three-in-one wireless microphone device for teaching, which aims to solve the problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a three-in-one wireless microphone device for teaching, which solves the problems. The three-in-one wireless microphone device for teaching comprises a wireless microphone base body, wherein a microphone is fixedly connected to the top of the wireless microphone base body, an electromagnet is fixedly connected to the top of the wireless microphone base body, a dust cover is movably connected to the top of the electromagnet, a ventilation bin is fixedly connected to the top of the dust cover, a filter screen is fixedly connected to the inner wall of the ventilation bin, an electric rotating rod is fixedly connected to the bottom of the filter screen, a rotating blade is fixedly connected to the side wall of the electric rotating rod, and a brushing mechanism is fixedly connected to the inner wall of the ventilation bin.
