Protective mask with internal air conditioning device

Abstract

The invention relates to the technical field of internal air conditioning of protective masks, in particular to a protective mask with an internal air conditioning device. The protective mask with the internal air conditioning device comprises an assembly head band, a transparent protective cover, a centrifugal fan and a lithium battery. The protective mask with the internal air conditioning device consists of an external threaded assembly rod, an assembly head hoop of an internal threaded locking cover and a transparent protective cover; the whole protective mask is assembled by adopting a split structure and can be quickly disassembled, separated and replaced; early-stage installation and later-stage disassembly and maintenance are facilitated, and the later-stage use cost is reduced; an air flow channel is formed inside the protective mask, and air circulation between the transparent protective mask and the face of a wearer is improved by guiding air from the outer side; hot air is prevented from being gathered on the face; the dryness of the surface of the protective mask can be kept, mist cannot be generated; the light transmittance and definition of the protective mask are guaranteed; and the protective mask is easy to operate and convenient to use.

Description

technical field [0001] The invention relates to the technical field of air conditioning inside a protective mask, in particular to a protective mask with an internal air conditioning device. Background technique [0002] The protective mask is an appliance used to protect the face and neck from flying metal debris, harmful gases, liquid splashes, metal and high-temperature solvent droplets. There are mainly welding masks, anti-shock masks, anti-radiation masks, anti-smoke and poisonous gas masks and heat insulation masks. [0003] With the spread of the new crown epidemic around the world, the demand for protective masks is also soaring. Medical protective masks are used to protect medical personnel and prevent patient droplets from contacting medical contacts. Medical personnel need to wear protective equipment Wearing protective equipment for a long time will cause medical workers to feel stuffy and uncomfortable, and will generate a lot of heat on the face. Traditional p...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, an improved protective mask with an internal air conditioning device is provided to solve the problem that the traditional protective mask has no air conditioning device, poor comfort, and affects medical services. Workers work, and at the same time, most of them are in one structure, which cannot be separated and disassembled, resulting in a relatively single scope of application. Once used, parts cannot be replaced, but the whole can only be replaced. Later, the cost will be high and the functionality is also very limited.
