Description
Technical field：
The utility model is related to a kind of protective mask, belongs to dust guard pollution abatement equipment technical field, specifically refers to a kind of with blower fan
Ventilated dustproof mask.
Background technology：
Existing anti-dust respirator is belonging to self-priming, and its respiratory cavity is enclosed structure, is exhaled when operating personnel wears
Inhaling can contain certain density carbon dioxide all the time in chamber, wearing can be atomized into steam for a long time, increased operating personnel's pendant
Sense of discomfort when wearing, in addition, being worn under the operating environment of dust concentration high, what the Dust Capacity on respiratory cavity can be over time prolongs
Grow and increase, respiratory resistance also can accordingly increase, cause operating personnel to produce feeling bad for shortness of breath uncomfortable in chest to feel, it is necessary to take often anti-
Dirt mouth mask is taken a breath, and is unfavorable for the individual dust-proof and physical and mental health of operating personnel, while retardation also can be caused to job scheduling.
Utility model content：
For the problems of background technology, the utility model targeted design, and then provide a kind of reasonable in design, knot
The compact dust-proof mask with blower ventilation of structure.
The utility model realizes that the technical scheme that its purpose is used is：A kind of dust-proof mask with blower ventilation, structure by
Outer cover, and filter layer and micro-blower inside and outside outer cover is constituted.Described outer covering on opens up on the wall of side
There is passage, an air valve is arranged with the outside of passage；Described filter layer is closely attached to the inner side of outer cover by swivelling cover,
Swivelling cover docks fixation with air valve；Described micro-blower is fastened integrally by upper casing, lower casing, and micro-blower is in its housing
Inside pasting circuit board, mini-fan and the lithium battery of interconnection, the wherein position of mini-fan and lower casing are installed
Air outlet position correspondence is consistent, and micro-blower is fastened and connected by lower casing with air valve.
The measure further taken is：Described air valve is the Non-return air valve being oriented to from the inside to the outside.
The utility model so design advantage be：Simple structure, practical, the paster electricity inside micro-blower
Road plate has the function of boost charge, can realize the effect of quick charge energy storage；Lithium battery have overlength service life and
Endurance, both bring out the best in each other；And filter layer can dismounting and change at any time, it is to avoid have influence on human body and be good for because laying dust is excessive
Health, the mouth mask has the effect of haze simultaneously, can effectively prevent the invasion of PM2.5, virus or bacterium to human body, generally
Convenience and security when improve workman's operation.
In addition, the utility model innovatively sets up micro-blower on outer cover, by the driving of lithium battery, mini-fan
The air inside outer cover is discharged in the way of unidirectional pump drainage, reaches the automatic effect more ventilated, and then elimination is felt oppressed
Phenomenon.
Brief description of the drawings：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is structural decomposition diagram of the present utility model.
In figure, 1, outer cover, 11, passage, 2, filter layer, 3, micro-blower, 31, upper casing, 32, lower casing, 33, paster electricity
Road plate, 34, mini-fan, 35, lithium battery, 4, air valve, 5, swivelling cover.
Specific embodiment：
The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Figure 1 and Figure 2, structure of the present utility model is by outer cover 1, and the filter layer inside and outside outer cover 1
2 and micro-blower 3 constituted.Described outer cover 1 offers passage 11 on the wall of side, and the outside of passage 11 is arranged with one
Air valve 4；Described filter layer 2 is closely attached to the inner side of outer cover 1 by swivelling cover 5, and swivelling cover 5 docks fixation with air valve 4；Institute
The micro-blower 3 stated is fastened integrally by upper casing 31, lower casing 32, and micro-blower 3 is provided with mutually in the inside of its housing
The air outlet of the pasting circuit board 33 of connection, mini-fan 34 and lithium battery 35, the wherein position of mini-fan 34 and lower casing 32
Position correspondence is consistent, and micro-blower 3 is fastened and connected by lower casing 32 with air valve 4.
Described air valve 4 is the Non-return air valve being oriented to from the inside to the outside, and this Non-return air valve is advantageous in that, in mini-fan
Under 34 guiding, air inside outer cover 1 can only flow along air valve 4 to the air outlet direction of lower casing 32, and lower casing 32 goes out
Air outside air port cannot but flow back, while new air is introduced by the gap on all edges after outer cover 1 is worn, for the personnel of wearing
Breathing, it is ensured that the freshness of air, it is to avoid what operating personnel produced shortness of breath uncomfortable in chest feels bad sense and phenomenon of feeling oppressed, and is not extracing mouth
In the case of cover, dust-proof, haze purpose is reached.
In addition, filter layer 2 is fitted in the inside of outer cover 1 by then passing through swivelling cover 5, filter layer 2 play filtering dust and
The effect of haze, only needs to outwards twist swivelling cover 5, you can unload filter layer 2 down and more renew after long-time use
Filter layer, the mouth mask has the effect of haze simultaneously, can effectively prevent the invasion of PM2.5, virus or bacterium to human body,
Safety and bodyguard when ensureing that next time uses, it is cost-effective without buying whole mouth mask again every time, embody its hommization and set
Meter.
