This scheme on-off, then the draught fan, ultraviolet lamp, plasma generator begins work, draught fan pulling air enters into in the passageway from the air intake, filter the cotton filtration through filtering earlier, then through the disinfection of disinfecting of plasma generator, then through UVC ultraviolet lamp secondary sterilization disinfection, ultraviolet lamp's bactericidal effect can be enlarged to the reflector panel simultaneously, then filter once more through the melt-blown cloth, blow off transparent face guard from the air outlet at last, the air after disinfection and the filtration of disinfecting repeatedly blows off with certain wind pressure, make the face guard inboard can not have the air through the disinfection, the air of air outlet is blowing transparent face guard always simultaneously, make fog can not appear on the face guard like this, thereby let medical staff and other special posts personnel can more clear sight, safer more comfortable facial environment goes to drop into the work.
Preferably, the cap shell is provided with one or two of a power-shortage warning buzzer and a power-shortage warning lamp, and the power-shortage warning buzzer and the power-shortage warning lamp are electrically connected with the power supply. After this scheme switch was opened, the buzzer on the cap shell can send the warning sound when external power supply lacks the electricity or unexpected outage, and the warning light can last the scintillation simultaneously to reach the suggestion of two safe lacks the electricity.
Preferably, the cap shell is provided with a power interface, and the power interface is electrically connected with the switch. This scheme protective face mask accessible dry battery, precious, lithium cell of charging etc. mode hand-carry or set up on the cap casing, then supply power after respectively with power and cap casing power source interface connection through the connecting wire.
Compared with the prior art, the invention has the beneficial effects that: the scheme can avoid the direct contact between the external environment and the breathing environment of medical workers (users), and can prevent the breathing of the medical workers from being condensed into fog in the transparent mask.
