At the same time, the deodorant effect of the existing masks is not good. To achieve a good deodorant effect, the deodorant layer must be thickened, but thickening the deodorant layer will cause poor breathing. Therefore, a new deodorant mask with breathing valve must be developed

Embodiment 2
[0037] In this embodiment, the breathing valve is screwed into the mounting hole. Articulation for easy disassembly. The breathing valve can be easily replaced. Threads are provided on the breather valve, and threads matching the threads of the breather valve are arranged in the installation hole. The threaded connection is easy to disassemble.
[0038] Other structures are consistent with embodiment 1.
Embodiment 3
[0040] Such as Figure 4Shown is a deodorant mask 100 with double breathing valves. In this embodiment, the elastic lace is a head-mounted elastic lace. The elastic lace is provided with an adjustment buckle 18, and the elastic lace passes through the adjustment buckle. Wearing the head-mounted elastic strap is more complicated than the ear strap, but the mask has better sealing performance. The setting of the adjustment buckle makes the length of the elastic strap adjustable, which is convenient for wearers with different head circumferences. There are 2 connectors in total, one on each side of the frame, so that the head-mounted elastic strap is tied to the connector.
[0041] Other structures are consistent with embodiment 1.
Embodiment 1
[0043] The manufacture process of the double breathing valve deodorant mask described in embodiment 1: put gauze, active carbon filter cloth, electrostatic dust collection filter cloth, spray glue cotton, non-woven fabric on the spherical abrasive tool, compress to form the mask layer, the mask layer The layer is convex; two installation holes are symmetrically opened on the mask layer, and the breathing valve is installed in the installation holes. Sew elastic cotton on the edge of the mask layer, elastic cotton forms a frame, prepares the preliminary shape of the mask, sews the elastic cotton into a ring-shaped connector, then sews the connector on the frame, passes the elastic lace through the connector, Sew the ends of the ties together to create looped ear loop ties that hang directly over the ears.

Abstract
The invention discloses an anti-odor mask with double breathing valves. The mask comprises a mask layer, a frame, a connecting piece, and an elastic lace. A frame is arranged on the edge of the mask layer, and connecting pieces are arranged on both sides of the frame. The inner layer, activated carbon filter layer, electrostatic dust filter cloth layer, spray-coated cotton layer, outer layer, and mask layer are sewn together from the inside to the outside. Including the base, upper cover, valve body, the base is movably connected with the installation hole, the base is connected with the upper cover, the valve body is installed between the base and the upper cover, the valve body is a one-way breathing valve body, the upper cover is provided with an exhalation hole, and the mask The upper part of the mask is set into a V shape that can wrap around the nose, and the lower end of the mask is set into an arc that can wrap around the chin. The double breathing valve is set to avoid stuffiness, good sealing performance, no leakage at the edge; good air permeability, smooth breathing after wearing, suitable for places with high temperature, high humidity and high stuffiness.
Description
technical field [0001] The invention relates to the field of masks, in particular to a double breathing valve deodorant mask. Background technique [0002] The emergence of the concept of PM2.5 air hazards in 2013 has aroused the public's attention to air pollution issues, making masks and other protective products very popular during smog weather. Masks are generally worn on the nose and mouth to filter the air entering the nose and mouth to block harmful gases, odors, and droplets. Masks can be divided into air filter masks and air supply masks. The masks used to prevent and control PM2.5 are air filter masks. [0003] Because masks are mostly made of non-woven fabrics, gauze, cotton and other fabrics, after long-term wearing, the heat generated during breathing is difficult to dissipate, which not only causes poor breathing, but also exhaust gases such as carbon dioxide from breathing will remain in the mask. The mask loses its original effect of filtering air. Therefo...
