Description
Technical field
The utility model relates to flusher, relates in particular to a kind of lid that dusts.
Background technology
The existing duster that is used to spray powder mainly sprays through dual mode.A kind of for utilizing air pressure directly will be positioned at the powder extrusion (below be called direct jet type) of container.
Number be 902015877 in one Chinese patent application, the day for announcing be Augusts 8 nineteen ninety day, be called in the patent documentation of " desinsection duster " and disclose a kind of direct jet type duster.This dusts and covers the jet pipe that mainly comprises the bottle that dusts, is arranged on the nozzle on bottle bottleneck that dusts and is positioned at the bottle that dusts, and nozzle is provided with the necking down spray orifice, and an end of jet pipe is connected on the inner of spray orifice.Through the extruding bottle that dusts, the pressure rises in the bottle that dusts makes a powder that is contained in the bottle that dusts behind jet pipe, from spray orifice, spray during use.
One Chinese patent application number for 91228594x, the day for announcing be September 23 in 1992 day, be called in the patent documentation of " miniature duster " and also disclose a kind of direct jet type duster.This duster mainly comprises dust nozzle, discharge tube, hollow rubber ball and the storage powder bottle that connects successively; Between hollow rubber ball and storage powder bottle, be provided with suction pipe; During use; To store up powder in the powder bottle in suction pipe is drawn onto the hollow rubber ball through the extruded hollow ball, released through discharge tube and dust nozzle by the air-flow that in the hollow rubber ball, outflows then, realize the function of dusting.
Though directly the duster of jet type is simple in structure but exist powder to spray uneven deficiency.
For the duster that solves direct jet type sprays uneven deficiency, designed the lid that dusts of another kind of spray pattern, the duster that promptly powder in the container is adsorbed away (below be called indirect type) through negative pressure.
Number be 2008201537593 at Chinese patent, Granted publication day is that the patent documentation that Augusts 12 in 2009, day, were called " duster " is disclosing a kind of indirect type duster.This duster mainly comprise container, three-way pipe structure shower nozzle, be provided with the spray ball (source of the gas structure) and the suction pipe of breather cheek valve, a port of shower nozzle with the spray ball be connected, another port of shower nozzle through suction pipe with container be connected, the 3rd port of shower nozzle be ejiction opening.During use; Through pushing the spray ball air-flow is sprayed from the ejiction opening of shower nozzle; Air pressure in this process in the ejiction opening of shower nozzle is lower than the pressure in the port that shower nozzle is connected with container; Powder in the container sprays in suction pipe is adsorbed onto shower nozzle and from bump outlet, unclamp after the pushing of spray ball, extraneous air in check valve enters into the spray ball, the spray ball is from newly heaving.
Not enough below existing though the duster of existing direct jet type sprays evenly: as the source of the gas structure all need to be set or to connect compressed gas source, cause complex structure, deposit inconvenience or use inconvenience.
