Description

Protective mask

Technical Field

The utility model relates to a face guard structure field, in particular to protective face guard.

Background

In the working environment, there may be various kinds of dangerous materials, such as spray, pollutant, pathogen, pollen, floating fine asbestos fiber dust, etc., which will cause serious injury if they are directly contacted or inhaled into the human body without being obstructed, so that the worker needs to wear protective clothing to avoid direct exposure to the dangerous materials.

In addition, in special occasions, such as industries such as semiconductor production, biochemical technology, precision machinery, pharmacy and hospitals, which are particularly sensitive to environmental pollution, environmental parameter conditions must be controlled within a certain required range so as not to affect the manufacturing process, wherein the semiconductor industry has particularly strict requirements on indoor temperature and humidity and cleanliness, and in order to meet the requirement of cleanliness, hairs, skin fragments, sweat and droplets of a human body cannot enter a working environment, so that substances affecting cleanliness are blocked between the human body and clothes through special clothes blocking.

In addition, the protective clothes such as dust-free clothes, antistatic clothes and the like which are commonly used at present are comprehensively covered on the whole body in an integrally formed manner, only the face and the hands and the feet are exposed, and then the systemic blocking effect is achieved through auxiliary protective accessories such as a face mask, a mouth mask, gloves or shoe covers and the like.

Because the human body is in a large-area isolation state, besides the dangerous substances or human body pollutants, heat energy and moisture emitted by the human body are blocked at the inner side of the protective clothing, so that the heat energy and the moisture of the human body generated in the work cannot be effectively emitted, and a worker is forced to be in a very hot working environment after wearing the protective clothing for a period of time, so that the working efficiency is reduced, and the working time of the worker can be greatly shortened.

Although the temperature is controlled to be in the range of 25 to 27 degrees by an air conditioner in a clean room in the high-tech field, and the air conditioner is used to maintain the temperature in hospitals, laboratories and the like, even if the air conditioner is available, a human body still feels quite hot and uncomfortable after wearing protective clothing or dust-free clothing.

Moreover, most working environments without air conditioning, such as chemical fiber or glass fiber processing, high pressure cleaning, oil groove cleaning or painting, will increase the psychological and physiological burden of the user when wearing the protective clothing to protect the user from the dangerous substances in the external working environment.

For the extreme stuffiness feeling generated by wearing the protective clothing, the prior art mostly improves the material of the protective clothing, and the excessive heat energy and moisture can be discharged by continuously improving the air permeability of the material. However, the improvement of the material has its limit to improve the air permeability, and under the concept of isolation protection and air permeable heat dissipation, the protective clothes made of the material with high air permeability only has the air permeable heat dissipation effect like the salary of a cup car. Moreover, the price of the high air permeability material is quite expensive, so that the price of the protective clothing rises, which is a considerable production cost for manufacturers who need a large number of staff to wear the protective clothing or users who only need to wear the protective clothing in a few specific events, or is not good for the benefit due to the use times.
