Abstract
The invention provides an air-curtain type face mask, which comprises a face mask body, wherein exhaust ports are formed in the face mask body; air-curtain tube mounting holes are symmetrically formed in two sides of the middle of the face mask body; an air-curtain tube is fixedly arranged in the air-curtain tube mounting holes; a gas space is formed in the face mask body; the air-curtain tube transversely runs through the gas space; two ends of the air-curtain tube are fixedly arranged in the air-curtain tube fixing holes; by virtue of the air-curtain tube, the gas space is divided into an air-curtain space and a gas storage space; the air-curtain tube is connected to a gas delivery tube; and a gas supply device is connected to the gas delivery pipe. By virtue of an air-curtain face, the interior of the face mask body is kept under micro-positive pressure, so that the face mask can provide a comfortable and clean small respiratory environment to a user.
Description
Technical field
The present invention relates to face shield technical field, be specifically related to a kind of air-curtain type face shield.
Background technology
Gas mask provides a method that the clean gas of besoin de respirer can be transferred to human lung, leads now
The kinds such as the oxygen face mask that medical gas face shield to be had, aviation oxygen face mask and airline passengers use, for treatment disease, guarantor
Protect passenger and pilot plays an important role safely, mainly by plastics, organosilicon, or rubber makes, and gas mask may
Wrap up nose and face (oral cavity nose cup) or whole face (full facepiece mask), for ensureing health, protection pilot and aviation
Passenger safety plays an important role, and for gas mask of the prior art, often there is certain defect, such as
Full facepiece mask in-convenience in use, be suitable only for professional and use, and half face shield easily produces negative pressure and makes nose suck other gas
Body, breathes and has resistance, and in face shield, gas humidity is big, and temperature is high, uses and has certain inconvenience, uses the most for a long time.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art and a kind of air-curtain type easy to use, comfortable, portable is provided
Face shield.
The present invention solves that the technical scheme that the problems referred to above are used is:
The present invention provides a kind of air-curtain type face shield, including mask body, described mask body is provided with air vent, described face shield
In the middle of body, lateral symmetry is provided with air curtain tube installing hole, is fixed with air curtain tube, in described mask body in described air curtain tube installing hole
Portion is provided with the gas compartment, and described air curtain tube crosses the described gas compartment, and it is solid that described air curtain tube is fixed at described air curtain tube two ends
Determining in hole, the described gas compartment is divided into air curtain space and gas storage space by described air curtain tube, and described air curtain tube connects supplies gas
Pipe, described snorkel connects gas supply device.
Further, described air vent is no less than 1.
Further, described mask body is half face shield.
Further, described air curtain tube being provided with upper and lower two row's fumaroles, the air curtain of lower row's fumarole ejection enters gas
Curtain space, be used for blocking air vent, the entrance of other gases outside stop, and described air curtain interior volume formed micro-just
Pressure.
Further, the cumulative volume of described air curtain space and gas storage space is between 200-500mmL.
Further, the gas flow that air curtain is formed is: 20-50L/min.
The beneficial effects of the present invention is:
A kind of air-curtain type face shield proposed by the invention, air curtain space is produced gas jet by air curtain tube and forms air curtain, stops
Outside gasses refluxes, and meets the inspiratory demand of people simultaneously, gas storage space on the top of cover body, a kind of air-curtain type proposed by the invention
Face shield, in use ozone enters air curtain tube from snorkel, is full of fresh in gas storage space and air curtain space
Air, user sucks ozone from gas storage space, the gas of exhalation with air curtain jet from air vent get rid of, such nothing
Opinion all allows user breathe fresh gas under any state, and the physical and mental health for user provides sound assurance.

Detailed description of the invention
The most specifically illustrating embodiments of the present invention, accompanying drawing is only for reference and explanation uses, and it is right not constitute
The restriction of scope of patent protection of the present invention.
As shown in Figures 1 to 6, the present invention provides a kind of air-curtain type face shield, including mask body 1, described mask body 1 is arranged
Air vent 2, the described middle lateral symmetry of mask body 1 is had to be provided with air curtain tube installing hole 3, fixing in described air curtain tube installing hole 3
Having air curtain tube 4, described mask body 1 to be internally provided with the gas compartment 11, described air curtain tube 4 crosses the described gas compartment 11, described
Air curtain tube 4 two ends are fixed in described air curtain tube fixing hole 3, and it is empty that the described gas compartment 11 is divided into air curtain by described air curtain tube 4
Between 111 and gas storage space 112, described air curtain tube 4 connects snorkel (being not drawn in figure), and described snorkel connects has gas to send out
Generating apparatus (is not drawn in figure), and this gas generating unit is oxygen generator.
In the present embodiment, described air vent is 1.
In the present embodiment, described mask body 1 is half face shield.
In the present embodiment, described air curtain tube 4 is provided with upper and lower two row's fumaroles 41, the air curtain of lower row's fumarole ejection
