Patent Name

   

A kind of dual valve mask

   

Applicant

   

Zhongke Beisida Environmental Technology Co. ,LTD., Xiamen

   

Patent No.

   

CN201610379933.5

   

Summary

   

A kind of dual valve mask, included main shell body, one-way inlet valve, one-way exhaust valve, air filter material, protective fitting and leakproof ring. The main body shell arched to the opposite direction of the air admission, formed a half shell construction. One side of the main shell body open, formed a wearing open. The leakproof ring winded round the wearing open. There’s an air inlet on the main shell body. Along the direction of the inlet,  successively arranged protective fitting, air filter material and one-way inlet valve. The one-way exhaust valve is inside the main shell body. When inhaling, the air enters from the one-way inlet valve. When expiration, the air exhausts from the one-way exhaust valve. That avoided the breath moisture absorbed by the filter element which would decline the filter efficiency and increase the resistance. This invention used air filter material, especially used the nanofiber membrane which manufactured by electrospinning technology, had ultra small diameter, compact fiber and high filter efficiency. The mask has good filter effect, thin and soft, long service life, comfortable to wear.
