Work order is sent to speed regulation circuit for fan 14, speed regulation circuit for fan 14 is according to received work order, and generation is accordingly
Work order, and Miniature brushless motor fan is sent to, Miniature brushless motor fan work is controlled, due to Miniature brushless motor wind
The working air current direction of fan backwards to cephalad direction, two gas-guide tubes 4 abut each other the air-flow of end and Miniature brushless motor fan into
Enter end face to be connected to each other, the port of two gas-guide tubes 4 is respectively communicated with the exhaust cavity between outer outlet body 7 and interior cover body 8, then based on micro-
The airflow direction of type brushless motor fan work, the air between outer outlet body 7 and interior cover body 8 in exhaust cavity is by rapidly through air guide
Pipe 4 carry out it is outer arrange, since the air in exhaust cavity is by quick outer row, then in exhaust cavity on the inside of interior cover body 8 between shape
Into draught head, under the action of draught head, the damp-heat air of interior 8 inside of cover body can through each pumping through hole 9 on interior cover body 8,
It is flowed into exhaust cavity rapidly, and under the airflow function of Miniature brushless motor fan work, further by gas-guide tube 4
Outwards discharge；The damp-heat air of 8 inside of cover body constantly carries out outer row in so, then interior 8 inside of cover body and 6 outside of tissue layer cover body
Between can also form draught head, so under the action of draught head, the air in the outside of tissue layer cover body 6 passes through tissue layer cover first
Body 6 then by noting sets of vias outside each group on outer outlet body 7 and interior cover body 8, with reference to each docks and sets of vias is noted outside each group respectively
Outer note snorkel 5 realizes the injection of inside 8 inside of cover body of extraneous air, since the both ends of note snorkel 5 outside each are docked respectively
It is noted outside corresponding and note through hole 11 outside through hole 10, second is noted outside first in sets of vias, then through the outer extraneous air noted snorkel 5 and injected
It is mutually independent, is independent of each other with the outer air-discharging in exhaust cavity, it is thus achieved that air displacement application so that designed
Medical gas displaced type mask provides more comfortable use feeling in practical applications, for user.At the same time, at ARM
In the case that reason device is based on Temperature and Humidity result more than or equal to default Temperature and Humidity result threshold value, through speed regulation circuit for fan
During 14 are controlled for Miniature brushless motor fan, if Temperature and Humidity result continues to increase, arm processor to
Speed regulation circuit for fan 14 sends rotating speed increase instruction, and speed regulation circuit for fan 14 increases instruction, control according to received rotating speed
The rotating speed of Miniature brushless motor fan is improved, increases air flow power caused by Miniature brushless motor fan work, accelerates air
Displacement efficiency；If Temperature and Humidity result is in the case of more than or equal to default Temperature and Humidity result threshold value, lasting to reduce,
Then arm processor sends rotating speed reduction instruction to speed regulation circuit for fan 14, and speed regulation circuit for fan 14 is according to received rotating speed
Reduce instruction, control reduces the rotating speed of Miniature brushless motor fan, reduces air-flow caused by Miniature brushless motor fan work
Power reduces the rate of air displacement, is thus based on the detection of Temperature and Humidity result, and intelligence adjusts Miniature brushless motor fan
Rotating speed.
Embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode, within the knowledge of a person skilled in the art, can also be on the premise of present inventive concept not be departed from
It makes a variety of changes.
