This embodiment provides a protective facial mask, belongs to protective articles's technical field, has solved surgical facial mask among the prior art and has relied on filter core quality and can not wash the technical problem who recycles, and this protective facial mask has protecting effect good, and can high-quality reuse's technical effect.

Referring to fig. 1-4, in the present embodiment, the protective mask includes an outer shell 10, an inner shell 20, a filter 30, an air chamber 40, and a short wave ultraviolet sterilizer 50. Wherein the short wave ultraviolet ray sterilization device 50 is preferably provided as a short wave ultraviolet ray LED lamp and is mounted on the housing 10. As shown in fig. 1 and 3, an air inlet 11 is formed in a wall surface of the outer shell 10, the air inlet 11 includes a plurality of through holes formed in an outer wall surface of the outer shell 10, the outer shell 10 and the inner shell 20 are connected to form an inner cavity, and the air chamber 40 is disposed in the inner cavity and divides the inner cavity into a first inner cavity and a second inner cavity. In addition, a filter 30 is disposed in the first chamber and communicates with the air inlet 11, and the sucked ambient air is filtered by the filter 30. In addition, the inner shell 20 is provided with an air inlet check valve 21 and an air outlet check valve 22 on different wall surfaces, the first inner cavity is communicated with the air inlet 11 and the air chamber 40, and the second inner cavity is communicated with the air chamber 40 and the air inlet check valve 21. Wherein the air inlet check valve 21 only allows air in the second inner cavity to be unidirectionally sucked into the inner shell 20, and the air outlet check valve 22 only allows air in the inner shell 20 to be unidirectionally exhaled from the inner shell 20.

Preferably, the air compartment 40 is provided with a plurality of circuitous air channels 41, and the first inner cavity and the second inner cavity are communicated through the air channels 41, specifically, when the air compartment 40 is installed, the filter sheet 30 is clamped by the inner wall surfaces of the outer shell 10, and the inlet of each air channel 41 is correspondingly communicated with each air inlet 11, the unique design of the air compartment 40 increases the effective time of the air filtered by the filter sheet 30 in the air compartment 40, so as to perform disinfection and purification, and simultaneously prevent the droplet particles with bacteria and viruses from entering the inner shell 20 at the later stage, thereby avoiding the inhalation of the wearer.

In this embodiment, the outer shell 10 and the inner shell 20 are connected to form an inner cavity, the air chamber 40 is disposed in the inner cavity and divides the inner cavity into a first inner cavity and a second inner cavity, specifically, two outer side surfaces of the air chamber 40 abut against inner wall surfaces of the inner cavity to fix the air chamber 40, the inner shell 20 is detachably connected to the outer shell 10, specifically, the inner shell 20 is connected to the outer shell 10 through a movable buckle, the specific form is not limited, after the inner shell 20 is detached, the air chamber 40 can be cleaned, the air chamber can be installed again for use after cleaning, in addition, after the air chamber 40 is detached, the filter sheet 30 is no longer clamped by the inner wall surfaces of the air chamber 40 and the outer shell 10, at this time, the filter sheet 30 can be detached for replacement, and the high-quality recycling effect of the protective mask is ensured.

The protective mask of the present embodiment provides three degrees of protection to the wearer, wherein the first protection is to cover the filter sheet 30 installed at the air inlet 11 of the housing 10, and most of the droplet particles are filtered by the filter sheet 30 to isolate most of the bacteria; a second protection, which is a uniquely designed air chamber 40 that prevents bacteria from being directly inhaled into the wearer's respiratory system, and bacteria droplets that still enter the air chamber 40 through the filter 30 are blocked by a plurality of circuitous air channels 41; the third protection is a short wave ultraviolet sterilization device 50, the ultraviolet light beam generated by which can reach the position of the air chamber 40 to kill the virus still remaining in the air filtered by the air channel 41 of the air chamber 40; finally, purified and disinfected clean air enters the inner shell 20 through the air inlet one-way valve 21 and is inhaled by a wearer, and air exhaled by the wearer is exhausted out of the protective mask through the air outlet one-way valve 22 of the inner shell 20, so that smooth breathing circulation is realized.

The protective mask utilizes ultraviolet rays to disinfect and purify air in the air cabin 40, and utilizes the air outlet one-way valve 22 to ensure that air exhaled by a wearer does not pass through the filter element (the filter sheet 30, the air cabin 40 and the short wave ultraviolet ray sterilization device 50), so that the service life of the filter element can be prolonged. In addition, the protective mask can enable a wearer to inhale the sterilized and purified air, simultaneously eliminates the feeling of stuffy hair treatment when wearing a common surgical mask, is suitable for people needing exercise amount, and is particularly suitable for people who wear the mask for a long time.

In addition, in this embodiment, the protective mask further includes two ear belts, the two ear belts are respectively disposed on two sides of the inner shell 20, when the wearer uses the protective mask, the ear belts are hooked on the ears to wear the protective mask, one surface of the inner shell 20 contacts the face of the person, the opposite surface faces the air chamber 40, and the adjacent surface is disposed with the air outlet one-way valve 22.

In this embodiment, preferably, the inner shell 20 close to the face is made of a silica gel material, and the air chamber 40 and the outer shell 10 are made of a PP material, so that the assembled protective mask is not easy to deform, and the air chamber 40 at the later stage is convenient to detach and clean, thereby further ensuring the high-quality recycling effect of the protective mask.

In this embodiment, when using this protective mask, ambient air is inhaled through the air inlet 11 of shell 10, and filtered by the filter 30 and the circuitous air channel 41 of air cabin 40 in proper order, disinfect through shortwave ultraviolet sterilization device 50 afterwards, clean air after the disinfection and purification gets into in inner shell 20 through air inlet check valve 21, let the person of wearing inhale again internal, and the gas that the person of wearing exhales then discharges this protective mask through air outlet check valve 22, this protective mask provides the three degree protection to the person of wearing when using, the protecting effect is good, and exhale gas can not pass through the filter core (filter 30, air cabin 40, shortwave ultraviolet sterilization device 50), can increase the life of filter core, can eliminate the vexed sense of baking of wearing general surgery gauze mask more.

The above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, the present invention has been described in detail with reference to the preferred embodiments, and those skilled in the art should understand that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all the solutions should be covered in the scope of the claims of the present invention.
