Ventilation and heat dissipation device for mask

Abstract

The invention provides a ventilation and heat dissipation device for a mask. The ventilation and heat dissipation device comprises a shell base, a shell upper cover covering the shell base, a micro heat dissipation fan, a direct-current power source, a temperature measurement sensor and a control module; wherein the micro heat dissipation fan, the direct-current power source, the temperature measurement sensor and the control module are installed in the shell base; the shell base is fixedly connected with the mask through a detachable locking structure; the direct-current power supply is usedfor supplying power to the micro heat dissipation fan; the micro heat dissipation fan is used for supplying air to the inner side of the mask; the temperature measurement sensor is installed in the center of the miniature heat dissipation fan and used for monitoring the temperature of the inner side of the mask and uploading the temperature to the control module. The control module generates a control instruction according to the temperature monitored by the temperature measurement sensor to adjust the air volume fed into the inner side of the mask by the micro heat dissipation fan in real time. The universality and interchangeability matched with the mask can be improved, the economic cost is reduced, the temperature between the mask and the face can be monitored in real time, the temperature between the mask and the face is adjusted, and a wearer wears the mask comfortably.

Description

technical field [0001] The invention relates to the technical field of mask heat dissipation, in particular to a ventilation and heat dissipation device for a mask. Background technique [0002] Masks are very commonly used protective equipment in medical units, industrial production and daily life. They are divided into various types according to different usage requirements, such as: ordinary cotton masks, medical surgical masks, and N95 masks. Ordinary cotton masks can filter large particles of dust or be used to keep warm in winter. Medical surgical masks can also filter tiny viruses, bacteria and other microorganisms. N95 masks have stronger protection capabilities and are generally suitable for occasions where they come into contact with patients with respiratory diseases. [0003] Different masks use different materials and manufacturing processes, but the common feature is that the filtering ability decreases after soaking. When wearing the mask for a long time, a ...

Problems solved by technology

[0003] Different masks use different materials and manufacturing processes, but the common feature is that the filtering ability decreases after soaking. When wearing the mask for a long time, a large amount of water vapor exhaled from the mouth and nose and skin sweat will soak the mask, resulting in a loss of virus protection. Reduce or even fail, more likely to cause skin discomfort

At the beginning of 2020, due to the ravages of the new coronavirus, it is required to wear a mask to enter public places. When the human body exercises a lot or in summer with the increase of body heat dissipation and sweating, the above problems are more prominent, and even many people are unwilling to wear masks. , which is very detrimental to the epidemic prevention and control work

[0006] (1) Both the mask body and the ventilation and heat dissipation device are individually designed by the manufacturer. A ventilation and heat dissipation device of a certain brand can only be used with masks of the same brand. Universal connection interface, poor versatility and interchangeability

[0007] (2) Both the mask body and the ventilation and heat dissipation device are custom-designed, which increases the overall cost and price of the mask, making it difficult to use widely

[0008] (3) The fan control method in the ventilation and heat dissipation device is simple switch control, and manual adjustment is required for opening, closing, and gear control, and there is no automatic air volume adjustment function based on temperature and humidity
