Furthermore, the width of the inner cavity of the air outlet channel is gradually increased from the second air inlet to the second air outlet.
The beneficial effect that adopts above-mentioned technical scheme to produce is, through the wind channel that expands gradually, has reduced the wind noise.
Further, an included angle α between the air outlet direction of the second air outlet and the horizontal plane is 15 °.
Adopt the beneficial effect that above-mentioned technical scheme produced, can make wind blow to the face guard body, and not directly blow the face, so very comfortable nature still can take away the inside steam of face guard body, remains throughout fog-free, and the sight is clear to unanimous with the old air direction of nose exhalation, the discharge of the old air of exhalation accelerates, remains throughout the largest amount of fresh air, can not lead to oppressing.
Further, the mask body is provided with a soft silica gel wrapping edge.
The beneficial effect that adopts above-mentioned technical scheme to produce is, can play the sealed effect of facing.
Further, the battery is rechargeable battery, and top cap body outer wall one side is equipped with and is used for giving the Type-c that the battery charges mouthful.
Further, the battery is a No. 5 or No. 7 battery.
Furthermore, an insect prevention grid net is arranged on the first air inlet.
Adopt above-mentioned technical scheme to produce beneficial effect be, can prevent that the mosquito from flying into air inlet duct and blockking up wind channel or first filter through first air intake, guarantee that air inlet duct and first filter have good performance.
Furthermore, the mask body is made of transparent materials.
The technical scheme has the beneficial effects that the transparent mask can show the whole facial features, so that the application of face recognition can be realized without taking off the mask.
