A kind of filtering breathing mask and using method thereof

Abstract

The application relates to a filtering breathing mask and its use method, which includes a mask body, the mask body is provided with an inhalation port and an exhalation port, the inhalation port is fixedly connected with an inhalation valve, and the exhalation port is fixedly connected with an exhalation valve , the inhalation valve is connected with a poison box, the inhalation valve includes an inner ring and an outer ring, and a limiting cavity is set between the inner ring and the outer ring, the poison box is fixedly connected with a clamping post, and several locks are arranged at angles such as the clamping post Tightening assembly, the locking assembly includes a strip groove, a stopper, two locking blocks slidingly connected with the strip groove, a number of springs are arranged between the locking block and the stopper, and the inner ring and the outer ring are provided with transverse cavities , by setting the locking component, when the clamping column moves to the limit position, the two locking blocks of the locking component are respectively clamped into the transverse cavity of the inner ring and the outer ring, so as to realize the fixing of the drug cartridge and the suction valve, several locks The tight blocks are all inserted into the transverse cavity, so that the clamping column is not easy to move relative to each other in the axial and radial directions, the fixing effect is better, and the connection between the poison filter box and the suction valve is relatively firm.

Description

A kind of filtering breathing mask and using method thereof technical field [0001] The application relates to the field of respiratory mask production, in particular to a filter type respiratory mask and a method of use thereof. Background technique [0002] At present, some enterprises will produce a lot of dust due to raw materials during production, and the dust will enter To the respiratory tract, too much dust enters the lungs, causing great harm to the body, and the sight of the eyes will also be greatly affected. Enterprises will require employees to wear breathing masks, which can absorb small particles and toxic and harmful gases. Filter out safe and breathable air. Use a breathing mask to prevent dust from entering the respiratory tract, which can protect the body It is necessary to wear a breathing mask. In the prior art, the respiratory mask is usually composed of an exhalation valve, an inhalation valve, a filter cartridge and a cover body. Filter ads...

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when the gas filter box is assembled on the inhalation valve, it is generally assembled manually. During the manual assembly, there are many uncontrollable factors, and the gas filter box is easy to appear in the assembly process. The connection of the suction valve is not strong enough, which makes the connection between the filter box and the suction valve easy to loosen or break, which increases the reject rate of the product and the finished product
