Problems solved by technology

[0004] Although the fan used as the power air source in the above solution can realize the function of conveying air, because the fan in the prior art usually generates vibration when it is working, the continuous vibration will not only generate noise, but also because the air purifier is mounted On the user's body, the user will feel the vibration of the fan, which will cause discomfort to the user and reduce the user's experience effect

Abstract

The invention belongs to the technical field of a respiratory protection device, and particularly discloses a damping structure for a respirator. The damping structure comprises a face mask, wherein the face mask sequentially communicates with a fan and a filter, the fan is arranged in the filter, a damper is fixedly connected to the outer wall of the fan, and the end, away from the fan, of the damper is fixedly connected to the inner wall of the filter; and the damper comprises a flexible vibration absorption pad, the vibration absorption pad is in a structural shape of two mutually symmetricand overlapped cone frustums, and the vibration absorption pad is fixedly connected between the filter and the fan. The invention aims to provide the damping structure for the respirator to solve thetechnical problem about fan vibration of the respirator.

Description

technical field [0001] The invention belongs to the technical field of respiratory protective devices, and specifically discloses a shock-absorbing structure for a ventilator. Background technique [0002] Air supplied respirators are often worn in environments where the ambient air contains or may contain contaminants. Clean air delivered to the wearer comes from a supply container or a powered air source that directs or drives ambient air through the air filter. [0003] For example, the Chinese utility model patent (publication number: CN205252345U) discloses a kind of intelligent fresh air respirator, which includes a mask to be worn and an air purifier connected to the mask through an air duct. The air purifier has a built-in air filter and is equipped with a charging power supply , power switch, power indicator light, fan and other accessories. [0004] Although the fan used as the power air source in the above solution can realize the function of conveying air, beca...
