Respirator with novel breather valve

Abstract

The invention discloses a respirator with a novel breather valve. The respirator comprises an outer respirator body and a filtering inner respirator body which is detachably connected to the inner side of the outer respirator body in an attachment mode, the breather valve is fixed at the lower portion of the outer respirator body, and a groove is formed in the end, located on the inner side of the respirator, of the breather valve. A hole is formed in the position, corresponding to a valve body, of the filtering inner respirator body, a plastic sleeve is fixedly connected to the peripheral edge of the hole with an ultrasonic welding technology, and the plastic sleeve is clamped in the groove of the breather valve in an interference fit mode. The respirator is divided into the outer respirator body and the filtering inner respirator body; after the respirator is used, the filtering inner respirator body can be abandoned, and the outer respirator body can be left; by means of split structural design, material waste can be reduced, and the environmental requirement is met; meanwhile, the plastic sleeve is fastened on the valve body in a sealed and sleeved mode, it can be guaranteed that the good dust prevention effect of the respirator is achieved, and the combination immobility of the filtering inner respirator body and the outer respirator body is strengthened.

Description

technical field [0001] The invention relates to the field of civilian masks, in particular to a mask with a novel breathing valve. Background technique [0002] With the development of industry and the popularization of private cars, the problem of urban air pollution is becoming more and more serious, especially the excessive PM2.5 content, which seriously affects the health of people traveling. In order to reduce the inhalation of excessive harmful substances, wearing a mask is a common preventive measure. Unlike the most primitive one-piece mask, the existing masks generally have a breathing valve, which greatly improves the smoothness of the wearer's breathing . [0003] However, the civilian masks and labor protection masks with exhalation valves on the market have the following defects: one, the exhalation valve itself is a part of the discarded mask or is installed on the consumable part of the replaceable mask, which causes waste of materials , is not conducive to ...

Problems solved by technology

[0003] However, the civilian masks and labor protection masks with exhalation valves on the market have the following defects: one, the exhalation valve itself is a part of the discarded mask or is installed on the consumable part of the replaceable mask, which causes waste of materials , is not conducive to reducing manufacturing costs, and does not meet environmental protection requirements; 2. The sealing between the breathing valve and the main body of the mask is not high, and it is easy to leak air after long-term use, which seriously affects its performance of blocking harmful substances
