2results about How to "Good dustproof function" patented technology

The utility model belongs to microphone technical field, concretely relates to a dustproof microphone, including base and microphone body, the base upside is equipped with the U -shaped support, and the microphone body both sides are rotatoryly installed on the U -shaped support through the pivot, and the microphone body upside is provided with dust screen, the dust screen is composed of filter layer and electrostatic adsorption layer, and the electrostatic adsorption layer is located in the inside of filter layer, and the filter layer is made of stainless steel mesh, and the electrostatic adsorption layer is made of electrostatic fiber filter material, the dust screen of microphone adopts filter layer and electrostatic adsorption layer double -deck structure, and the filter layer is made of stainless steel mesh or high -density plastic net, and the strength is high, and it is not easy to deform, and its wave -shaped structure increases the filtration area, reduces the airflow resistance, and can effectively intercept big particle, the electrostatic adsorption layer is made of electrostatic fiber filter material, and the surface is loaded permanent electrostatic charge, can high -efficiently capture tiny particle, simultaneously allows the sound wave to pass, guarantees the effect of receiving sound while, realizes good dustproof function.

The utility model relates to the field of silencers, and discloses a fan inlet silencer convenient to install, which comprises a silencer main body, the right side of the silencer main body is fixedly connected with a connecting pipe, the top end and the bottom end of the connecting pipe are provided with reinforcing plates, the reinforcing plates are movably hinged with installing plates, and the installing plates are fixedly connected with the silencer main body. A sound insulation layer is fixedly connected into the silencer body, a noise reduction sleeve is installed on the inner side of the sound insulation layer, and a first sound insulation sleeve is installed on the inner side of the noise reduction sleeve. According to the fan inlet silencer convenient to install, the noise reduction strength is improved through the multi-layer noise reduction and sound insulation structure, in the using process, the noise sensor can monitor noise in real time, once the noise exceeds the value, the terminal alarm module can give an alarm remotely, workers are reminded to replace and maintain the structure in the silencer body, and the noise reduction effect is improved. During maintenance and disassembly, the dustproof plate needs to be taken down firstly, then the sound insulation layer, the noise reduction sleeve, the first sound insulation sleeve and the second sound insulation sleeve can be pulled outwards one by one, and the problem that disassembly and replacement are inconvenient is solved.
