Among the preferred technical scheme "generate air curtain barrier device" for both ends take into the air flue, be the banding, there is the cavity in the middle, and there is the air vent of airing exhaust below, and there is the head fixed band both ends, can wear the device at the arc plastics material of forehead portion.
The preferred technical scheme is that the air inducing device is a square box with a mobile power supply, an induced draft fan, an air inlet and an air outlet.
In the preferred technical scheme, the air supply device is a Y-shaped flexible air supply pipeline (hereinafter referred to as a "Y-shaped pipeline").
The preferred solution is that the auxiliary device comprises: transparent cover piece support, set screw.
And fixing the transparent mask sheet on the transparent mask sheet bracket, bending the transparent mask sheet and the transparent mask sheet in an arc shape, and placing the transparent mask sheet and the transparent mask sheet in front of the air curtain barrier generating device to enable the transparent mask sheet and the transparent mask sheet to be close to each other. The two ends of the bracket with the transparent mask sheet are connected with the two ends of the 'wind curtain barrier generating device' through screws, and the bracket can turn over by taking the screws as shafts. And connecting the air inlet channels at two ends of the installed air curtain barrier generating device with two head ends of a Y-shaped pipeline, and connecting the other end of the Y-shaped pipeline with an air outlet of an air inducing device.
The induced draft device is fixed behind the arms or the waist. And connecting the head fixing belts at the two ends of the connected 'wind curtain barrier generating device' and wearing the head fixing belts on the head. Placing the transparent mask piece in front of the face creates an opposing semi-open space between the mask and the face that is closed at the top, open at the bottom and open at the sides. The induced draft device is started, and air is sent to the air curtain generating barrier device through the Y-shaped pipeline and then is exhausted through the air exhaust hole at the lower part, so that an air curtain is formed between the face mask and the face and covers the face; when the air curtain flows out from the gap formed by the face and the transparent mask, an airflow blocking barrier is formed to block the entrance of outside air.
(III) advantageous effects
By adopting the prior technical scheme, the invention realizes the purpose of forming the air curtain barrier between the transparent mask and the face after opening the air inducing device by applying the air curtain barrier generating device with the arc-shaped cavity with the air inlet passage and the lower air exhaust hole and additionally arranging the air inducing device and the air supply device.
Forming the air curtain barrier has the following beneficial effects: the air curtain flows through and covers the face, so that the pollution of air with spray or dust to the mouth, the nose, the eyes and the face can be effectively prevented; the air curtain brings fresh air to the user and takes away the gas exhaled by the user, so that the feeling of stuffiness can be effectively prevented; the air curtain can take away the heat and the water vapor exhaled by the user, can prevent the face from generating sultry sweating conditions, and can also prevent the transparent mask from forming mist; the air curtain flows out from the gap between the lower part of the face mask and the side opening and forms an air flow barrier, so that air with spray or dust can be effectively prevented from entering the space between the face part and the transparent face mask through the gap between the lower part of the face mask and the side opening.
In conclusion, the wind screen type mask disclosed by the invention better avoids various defects existing in the use of the existing transparent protective mask, is simple in structure, convenient to use and easy to clean, and can better ensure the body health of a user.
