Description

Multi-operational position powder blower

The utility model relates to a kind of powderject device, particularly relates to a kind of dusting device of inner multistation.

The diffusing type medicament of adding medicine in the mode of dusting in the Chinese and Western medicine has that water melon frost, sore-throat are loose, Bingpeng San, xilei san etc., and these medicinal powder are loaded in the flexible plastic bottle, and the nozzle of bottle connects a hard hollow pipe at the bottom of extending bottle, and the mouth of pipe is not among medicinal powder.When squeezing bottle, medicinal powder just is pressed in the pipe and crosses the nozzle ejection with air communication.Some medicinal powder is less because of dosage, as Bingpeng San, xilei san, then medicinal powder will be placed paper roll, aims at the wound top blast and applies medicine.

All there is following shortcoming in said method: it is inhomogeneous that (1) goes out dose, when the hard tube mouth contacts not as good as medicinal powder, do not go out medicinal powder; (2) application mode is particularly blown in operation inconvenience, the formality trouble, and unhygienic; (3) the medicine-feeding direction is restricted, as squeezes bottle, can only upwards spray medicine, blows application mode and then can only horizontal direction add medicine to, and then can't add medicine to if change direction; (4) waste is serious, always has quite a few medicinal powder discarded because of can not spraying in the bottle, and the medicinal powder that is spread mistake owing to operation inconvenience also is many.

The purpose of this utility model provides a kind of improved dusting device, has multistation, can be accurately, dust equably, and noresidue medicinal powder, one-handed performance only carries, uses and be conveniently.

A kind of multistation duster described in the utility model, it comprises container, hollow pipe and nozzle, the other end of nozzle connects hollow pipe, has the hole on the hollow tube wall on nearly container top, but is with outside the hollow pipe tapping slidably and the sleeve pipe of cover apertures.

With reference to the accompanying drawings the utility model is elaborated below.

Fig. 1 is a kind of straight type tubular construction schematic diagram of multistation duster.

Fig. 2 is the straight type tubular construction schematic diagram of above-mentioned duster band flexible pipe.

Fig. 3 is the straight type tubular construction schematic diagram of above-mentioned duster band flexible pipe and counterweight ring.

Fig. 4 is the bend pipe structure schematic diagram of above-mentioned duster band flexible pipe.

Fig. 5 is the bend pipe structure schematic diagram of above-mentioned duster band flexible pipe and container cinclides.

With reference to Fig. 1, in a compressible container 1, the other end of a nozzle 2 connects a hollow pipe 3, has a hole 4 at least on the tube wall at the nearly nozzle of hollow pipe 3 epimeres 2 places, but is with slidably the also sleeve pipe 5 of cover apertures outside perforate hollow pipe on every side.When container was upright, the hole was promptly by sleeve closure.Hollow pipe 3 hypomeres extend to container bottom.

During use, squeeze container and upwards spray medicine, because hollow pipe epimere aperture is by sleeve closure, air driven medicinal powder is pressed in the hollow pipe, by the nozzle ejection, finishes thus and dusts.Certainly, when container is upright, not sealing fully of hole on the hollow pipe, the part air enters in the hollow pipe by the gap between sleeve pipe and the hollow pipe, forms the air shunting, has improved the powder delivery uniformity thus.

Container is inverted spray medicine downwards, sleeve pipe because of gravity to lower slider, expose hole on the hollow pipe, aperture contact medicinal powder, hole or lower end then disengage with medicinal powder under the hollow pipe, are exposed in the air in the container, squeeze container, air-flow is brought medicinal powder into from last hole in the pipe, sprays from nozzle.

See Fig. 2 again, hollow pipe is made of an above pipe, wherein has a root system flexible pipe at least.Be connected with flexible pipe 6 between two hollow pipes (going up hollow pipe 7 and following hollow pipe 8).Have at least a root system to stretch to the straight type pipe 8 of container bottom in the hollow pipe.Flexible pipe 6 is made by flexible material, also can be made into flexible patterns such as bellows.Hollow pipe 8 hypomeres can be swung, the mouth of pipe near or touch arbitrary position of container bottom.

The end of the nearly container bottom of hollow pipe is equipped with the counterweight ring.Counterweight ring 9 is equipped with in the lower end that Fig. 3 illustrates down hollow pipe 8, to improve the amplitude of fluctuation of hollow pipe 8 down.

When spraying medicine, the outer sleeve pipe of hollow pipe is in the position that the hole is gone up in sealing when flat, and the pipe hypomere mouth of pipe or aperture still keep contacting with medicinal powder with the gravity effect because of flexible, squeeze container, still can normally spray medicinal powder.

The hypomere that Fig. 4 illustrates hollow pipe takes the shape of the letter U, and the hollow pipe that stretches to container bottom is a bend pipe 10, has aperture 11 on the bend pipe wall.That is to say that hollow pipe bends upwards, forms U-shaped, has a hole at least in U type pipe bottom near the bottom time.

When the container pressurized, air enters in the pipe from the bend pipe mouth, forms air-flow, and the pipe internal pressure is lower than container pressure, and medicinal powder just is inhaled into from the tapping of bend pipe, crosses the nozzle ejection with air communication.

Have the hole 12 that can connect compressed gas source on the chamber wall of Fig. 5.Hole 12 is communicated with an elastic hollow spheroid 13.When squeezing elastic hollow spheroid 13, air enters and drives medicinal powder in the container, finishes the action of dusting.This multistation duster has the practical application meaning industrial, as is used for the structure of dusting of fire-fighting dry powder extinguisher.

The work structuring of multi-operational position powder blower described in the utility model can add atmosphere/powder ratio, has guaranteed the uniformity of dusting. It also applicable to the spraying of other dispersion powders, such as powder type disinfectant, pesticide, mould inhibitor, extinguishing chemical, powdery paints etc., has the widely scope of application.

Claims (3)
