The specific working procedure is as follows:
when the device is needed to be used, the mask body 3 is worn on the face, the mouth and the nose are covered, then the switch is started, the motor 2 is controlled to rotate, the motor 2 can drive the rotating column 4 to rotate, the rotating column 4 can drive the fan blade 5 to rotate, through the fan blade 5, gas outside the power box 1 enters the power box 1 through the air inlet hole, the gas is automatically filtered through the filter cotton 7, and the filtered clean gas is led into the cavity above the partition board 6 to form certain air pressure; when the internal air pressure of the power box 1 is large, part of air is directly led into the mask body 3 through the second guide hole 12 and is finally sprayed outwards through the second air guide hole 13, and as the second air guide hole 13 is fully distributed outside the mask body 3, the air is sprayed through the second air guide hole 13 to enable a clean air environment to be formed near the face of a worker, so that the problem that dust particles are sucked into the body of the worker through a gap between the mask body 3 and the face is reduced; when the gas is introduced into the second guide hole 12, part of the gas enters the air cushion 14, so that the air cushion 14 swells, namely, when the mask body 3 is impacted outwards by the exhaled gas at the moment of exhalation of a person, the inflated air cushion 14 can fill a gap between the face and the mask body 3, and the problem of loose sealing of the mask body 3 is reduced; when a worker exhales, the air cushion 14 expands and bulges air, and the exhaled moisture can be reduced to be directly led out through the gap at the top of the mask body 3 through the convection effect of the air, so that the surface of wearing glasses is fogged, and the visual phenomenon is influenced; when in inspiration, the air pressure in the mask body 3 is reduced, the air in the power box 1 is directly led into the mask body 3, the air in the second air guide hole 13 is short in pressure, the air cushion 14 is contracted, the elastic sealing effect can be kept through the arc-shaped sealing elastic plate 16, meanwhile, when a worker exhales, the air cushion 14 is expanded again, the sealing elastic plate 16 can be directly extruded and deformed, the sealing elastic plate 16 can be automatically close to the small hole 15, the opening size of the small hole 15 is reduced, the air flow velocity sprayed by the small hole 15 is higher, the convection effect with moisture is improved, the moisture is led out through a gap, and the surface of the glasses is fogged; when a worker inhales and exhales, the elastic plate 19 can automatically swing, the sealing can be controlled through the swing of the elastic plate 19, and after the exhaled surplus gas is exhausted, the sealing can be automatically closed, so that the problem of gas waste caused by direct discharge of a large amount of purified gas through the gas outlet holes 17 is avoided; when the elastic plate 19 swings, the elastic plate 19 drives the elastic bags 22 on two sides of the elastic plate to stretch, so that gas in the elastic bag 22 on one side of stretching enters the elastic bag 22 on one side of compressing, the sealing effect on one side is improved, and the swinging amplitude requirement of the elastic plate 19 is reduced; by designing the end part of the elastic plate 19 into a V shape, the disturbance to the air flow can be improved during the exhaust, so that the air can continuously flow in a direction-changing manner, the overall blowing of the air near the mask body 3 is improved, and the dust is reduced to be near the mask body 3; by arranging the vibration balls 24 on the surface of the elastic plate 19, when airflow alternately flows, the airflow drives the elastic plate 19 to deform, so that two corresponding vibration balls 24 on the surface of the elastic plate 19 are continuously impacted, the elastic plate 19 is vibrated, the mask body 3 is vibrated, and the adhesion of dust on the surface of the mask body 3 is reduced; the vibration membrane 25 is arranged on the surface of the elastic plate 19, when air flows through, the vibration membrane 25 is driven to vibrate at a low amplitude and at a high frequency, meanwhile, the elastic plate 19 can completely and continuously extrude the elastic balloon 26, so that air in the elastic balloon 26 flows through the channel 27, vibration of the vibration membrane 25 can be increased, high-frequency vibration of the mask body 3 is realized through the vibration membrane 25, and cleaning of the surface of the mask body 3 is further improved.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
