Detailed description of the invention

Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.

The portable active inlet air of one as shown in Figure 1 purifies external member, mainly including depurator main frame 1 and the mask body with air valve 3, in depurator main frame 1, the clean air (PM2.5 clearance is more than 60%) of output is transported in mask body 3 by airway 2；Wherein:

Mask body 3 has the function of single standby ventilation, and can with face good fit；

Depurator main frame 1 mainly includes the lid 10 of filtration body 11 and matched fastening, and the functional unit being located at lid 10 includes:

(Micro) USB input port 4, for charging to depurator main frame 1；

Other equipment (such as mobile phone etc.) with charge function, for outwards electric discharge, are equivalent to the function of charger baby by USB delivery outlet 5；

Link 6, for being fixed on suitable position by depurator main frame 1；The knapsack that is equipped with when moving out of doors if desired for the long period, the parts such as cycle frame；

LED display 7, includes the parameter such as air PM2.5 numerical value after current time, battery electric quantity, purification for display；

Switch 8, for switching to work or off working state by depurator main frame 1；

Venthole 16 is connected with airway 2, for fresh air is led to mask body 3.

With further reference to Fig. 2; filtration body 11 mainly includes being provided with the post tubular shell in strip frame hole 9 and the active carbon filtration layer 12 being sequentially arranged in housing from outside to inside and Hai Pa filter course 13 along short transverse; wherein active carbon filtration layer is mainly used in absorption noxious substance and various gas with foreign flavor; sea handkerchief filter course is then mainly used in trapping 0.5um particles below dust and other float; being provided with power module 14 inside housing hollow within the handkerchief filter course 13 of sea, the top of housing 9 is provided with turbofan 15.According to the actual requirements, it is possible to the housing of filtration body 11 is become box-like from tubular, and other rational hoop closed type structures.

During work, air is by behind frame hole 9, inner chamber is arrived after purifying successively through active carbon filtration layer 12, sea handkerchief filter course 13, promote via the turbofan 15 at top, fresh air after purifying upwards is arrived through venthole 16 and after airway 2, leads to mask body 3, finally entering user pulmonary, the air of exhalation breathes out through the Non-return air valve of mask body 3.

The function of power module 14 contains power pack and observing and controlling part, observing and controlling part detectable go out venthole 16 place air pressure, flowing to the electric current of turbofan by controlling power supply, thus adjusting the rotating speed of turbofan, namely adjusting the duty of turbofan 15 according to air pressure；Specifically:

If the air pressure at venthole 16 place is higher than a certain setting high threshold, then observing and controlling part judges that user is in expiration state, reduces the air pressure at venthole 16 place now by reduction turbofan rotating speed, makes user exhale smooth and easy；

When the air pressure at venthole 16 place is lower than a certain setting Low threshold, then observing and controlling part judges that user is in suction condition, improves the air pressure at venthole 16 place now by increase turbofan rotating speed, makes user's air-breathing smooth and easy.

Concrete air pressure set threshold value by experiment, the science data of expertise and specialty pneumatology determine.It can be seen that the air pressure that this utility model makes venthole 16 place can adjust according to wearer's respiratory movement of mask body 3 end, it is ensured that wearer breathes air cleanliness that is smooth and easy and that suck.

Above in association with accompanying drawing, embodiment of the present utility model having been explained, accompanying drawing herein is used to offer and is further appreciated by of the present utility model.Obviously; the foregoing is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any be to one skilled in the art can readily occur in, essentially without departing from change of the present utility model or replacement, be also all contained within protection domain of the present utility model.
