A protective mask with internal air conditioning

Abstract

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, which includes an assembly headband, a transparent protective cover, a centrifugal fan and a lithium battery. A protective mask with an internal air conditioning device of the present invention is composed of an external thread assembly rod, an assembly headband of an internal thread locking cover, and a transparent protective cover. The entire protective mask is assembled in a split structure, which can be quickly disassembled, separated and replaced , to facilitate early installation and later disassembly and maintenance, and reduce later use costs; an air flow channel is formed inside the protective mask, and air is guided from the outside to improve the air circulation between the transparent protective cover and the wearer's face, avoiding hot air gathering on the face, and also It can maintain the dryness of the surface of the protective mask without generating fog, ensure the light transmission and clarity of the protective mask, and is easy to operate and 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.
