Filter dirt blast type anti-dust respirator of the present utility model, the back side of described dirt catcher housing is fixed with the charging socket that is used for to described batteries charging, and charging socket is electrically connected with battery pack.
Filter dirt blast type anti-dust respirator of the present utility model, the back side of described dirt catcher housing is fixed with power switch, and power switch is electrically connected with described battery pack.
Filter dirt blast type anti-dust respirator of the present utility model, the rear end of described dirt catcher housing is provided with belt clamp, and the two ends of belt clamp are provided with the punch holes that penetrates for belt.
The beneficial effect of the utility model filter dirt blast type anti-dust respirator is: the utility model is owing to adorned centrifugal blower in dirt catcher, it is air-breathing not need workman oneself to come, but extraneous dust laden air suction dirt catcher is filtered with the negative pressure that centrifugal blower produces, clean air after the filtration is sent into face shield by air supply duct and is made for industry personnel breathing, no steam in the face shield, thereby long service life.
Centrifugal blower is packed in the volute of blower, and the wind-force that impeller of blower is produced is more gone out from air outlet in the concentrated area, and wind-force is more stable.
Control button and circuit board make the personnel of wearing feel more comfortable by operating voltage of regulating centrifugal blower and then the size of controlling the centrifugal blower wind speed.
Belt clamp and punch holes are used for penetrating belt in use, by belt dirt catcher are fixed on one's body the staff, are easy to carry.
