Micro air current control module, use thereof and breathable mask made by using micro air current control module

Abstract

The invention relates to a micro air current control module and a breathable mask made by using the micro air current control module. The micro air current control module comprises a module concave surface consisting of a base and borders, wherein the module concave surface is provided two to fifty micro vent holes; each vent hole is covered with a duckbill valve. The micro air current control module has the characteristics of single-direction control of air current, simple structure, small size, easiness in industrial production and the like, and can be detached, replaced, cleaned and upgraded. The micro air current control model can be applied to masks, breathers, face masks, face shields, protection helmets and helmets. The breathable mask related to the invention comprises the micro air current control module, a mask main body, a filtering layer, a head belt and other auxiliary accessories. The mask has the advantages of filtering property, air permeability, avoidance of influence on vision, convenience in language communication during wearing, improvement on the durability and attractiveness of the mask, and easiness in industrial production.

Description

technical field [0001] The invention relates to a miniature airflow control module and its application, and also relates to a ventilating mask with the miniature airflow control module. It belongs to related technical fields such as daily civil use, labor protection and medical consumables or special occupational protection. Background technique [0002] Masks are widely used in the fields or industries of residents' life, medical care, labor protection safety and special occupations such as mining, emergency rescue and relief, sanitation and epidemic prevention, traffic command, fire protection and escape, police or military use, etc. There is an urgent need for effective warmth, Masks that are dustproof, protective, comfortable to wear, and affordable. At present, there are many types of masks on the market, which can be divided into two categories according to their structure and working principle: air filter masks and air supply masks. According to the functional class...

AI Technical Summary

Problems solved by technology

[0004] 2. Easy to fog and affect visual observation

When a person wearing glasses or a helmet drives a vehicle in winter, the water vapor in the exhaled gas is not easy to be discharged from the front, but is discharged from the upper part of the mask, fogging on the surface of the glasses or helmet mask, affecting vision, and possibly causing traffic accidents

In particular, if the disadvantage is more severe and prominent in medical, police or military applications

[0005] 3. High sealing affects language communication

Special occupations such as doctors, nurses, miners, traffic police, soldiers, etc. usually have frequent verbal exchanges, and the high sealing of masks prevents these users from communicating verbally in the working environment

Otherwise, the mask must be taken off and the protective effect of the mask will be lost, seriously affecting work efficiency and safety

[0006] 4. The water vapor in the exhaled air is easy to make the filter material of the mask invalid, and the mask body is wet or corroded metal parts

The mask involved in this patent has condensed water outflow holes, air exchange pipes, air filters and other accessories, which make the structure of the mask complex, which is not conducive to use and industrial production, and the condensed water outflow holes greatly reduce the heat preservation and protection effects.

China Patent Authorization Announcement No. CN202504233U utility model patent describes a breathable mask, which mainly solves the problem that the moisture in the mask cannot be excluded

The utility model is complex in structure, heavy in weight, has many accessories, is uncomfortable to wear, and is not easy for industrial production

China Patent Authorization Announcement No. CN202697798U utility model patent describes a utility model anti-eye fog mask, which is characterized in that there is an air outlet net layer at the position corresponding to the nostrils, which effectively prevents the exhaled hot air from being exposed from the mask and produces fog on the glasses, thereby affecting the eyes. visual effect, and at the same time lost the function of the mask to keep warm and protect

In short, the existing technology or design cannot simultaneously have the characteristics of high-efficiency filtration, good air permeability, wearing comfort and ease of industrial production of masks
