Abstract
The utility model provides a hand-operated type air filter blower, which comprises a box body, a wind wheel, a drug curtain, a gearbox, a transmission pair and a crank, the wind wheel is equipped in the box body, the drug curtain is provided at an air inlet of the box body, the shaft of the wind wheel is connected to the output shaft of the gearbox, the input shaft of the gearbox is connected to a driven wheel of the transmission pair, the crank is arranged on the shaft of the driving wheel of the transmission pair, the hand-operated type air filter blower is characterized in that the driven wheel of the transmission pair is a taxing wheel, and the blower is capable of operating with the help of inertia like a bicycle. The hand-operated type air filter blower has the advantages that the hand-operated type air filter blower can operate with the help of inertia, the physical energy consumption of an operator can be reduced, the wind power is stronger and the losing and slipping phenomena can not generate.
Description
Technical field
The utility model relates to filter gas blower fan.
Background technique
Existing shaking type filter gas blower fan, power comes from the operator, and the entire work process of blower fan requires the operator ceaselessly to shake crank, and the operator runs out of space.
Summary of the invention
The purpose of the utility model is the blower fan that provides a kind of inertia capable of using to work on.
The utility model provides a kind of shaking type filter gas blower fan, mainly comprises casing, wind wheel, medicine curtain, gearbox, transmission and crank, and wind wheel is housed in the casing; The casing intake grill hides has the medicine curtain; The axle of wind wheel links to each other with the output shaft of gearbox, and the input shaft of gearbox links to each other with the driven wheel of transmission, on the axle of the driving wheel of transmission crank is housed; It is characterized in that: the driven wheel of transmission is a slip wheel, and blower fan just can rely on inertia to continue operation as bicycle.
The shaking type filter gas blower fan that the utility model provides, its casing can be a volute type, and wind is compressed in spiral case better.
The shaking type filter gas blower fan that the utility model provides, the wind-force compression set can be equipped with in its casing exhaust outlet place, to improve the suction of air inlet.
The shaking type filter gas blower fan that the utility model provides, its medicine curtain can be equipped with the medicine (for example: carbon dioxide absorber, absorbent for carbon monooxide etc.) of adsorbable harmful gas, to reach the effect of filtering gas.
The shaking type filter gas blower fan that the utility model provides, its transmission can be that the sprocket wheel chain is secondary, in order to avoid belt transmission produces the phenomenon that throws switch.
The shaking type filter gas blower fan that the utility model provides, its gearbox and/or transmission can be accelerating units, to prolong the output of inertia.
The shaking type filter gas blower fan that the utility model provides, its advantage is: rely on inertia to continue operation, reduce operator's physical consumption, wind-force is stronger, can not produce the phenomenon that throws switch.
