In addition, the portable liquid nebulizer of the present invention further includes a shift lever 48 capable of adjusting the rotational speed of the blower fan 18b by adjusting the rotational speed (rpm) of the gasoline engine 20.

Hereinafter, the operation of the portable liquid nebulizer according to the present invention will be described.

When the operator starts the gasoline engine 20, the blowing fan 18b of the blower 18 directly connected to the driving shaft 20a of the engine 20 is rotated, so that the air introduced into the blower 18 is forced down and the blown air is forced down. Some of the air is supplied to the medicine container 24 and the automatic control valve 42 through the pressure control hose 44, and most of the other blowing air is the outlet duct 18a ', the blower pipe 28, and the reducer 32. Are sequentially passed through and supplied into the tube body 34d of the turning guide vane assembly 34.

As such, when the blowing air is supplied to the automatic regulation valve 42, the diaphragm 42d of the valve 42 moves the valve 42c downward while overcoming the holding force of the spring 42b. 42c is moved by a different amount depending on the air pressure of the blowing air.

That is, as the gasoline engine 20 is driven at a high speed by using the shift lever 48, the rotation speed of the blowing fan 18b is increased. Therefore, the air pressure of the blowing air is increased to increase the downward travel distance of the valve 42c, whereby a larger amount of liquid is discharged through the liquid conveying hose 40. Then, the liquid discharged through the liquid transfer hose 40 is inside the tubular body 34d through the hollow tube 34a of the swing guide vane assembly 34 and the nozzle 34b assembled at the end of the tube 34a. Is sprayed on.

On the other hand, the blown air passing through the blower pipe 28 passes through the reducer 32, and the flow rate is increased, and the blown air having the increased flow rate is forcibly turned while passing through the turning guide vanes 34c to generate vortices. Accordingly, the liquid sprayed from the nozzle 34b is atomized more effectively by the vortex and then sprayed out of the tube 34d through the nozzle 34e, and the liquid sprayed through the nozzle 34e is conventionally due to the vortex. It is transmitted over a distance of 30%.

Naturally, it belongs to the range of.

As described above, the present invention can remove the conventional liquid pressurizing pump by pressurizing the liquid using a part of the air pressure of the blowing air. Therefore, the weight of the apparatus can be reduced, and the blowing means (meaning the blowing fan and the gasoline engine for driving the fan) can be installed on the backrest for easy storage and use of the apparatus, and reduce the fatigue of the operator. have.

In addition, by increasing the flow rate of the blowing air generated in the blower by the reducer, whilst generating the vortex by rotating the increased blowing air can effectively atomize and spray the liquid, and increase the liquid spraying distance by more than 30% You can.

In addition, the liquid nebulizer of the present invention, because the liquid transfer hose is connected to the hollow tube of the swing guide vane assembly through the reducer, it is possible to omit the piping work outside the assembly, the operator can freely manipulate the assembly It works. In addition, there is an effect that the air flow at the outlet of the assembly is improved by about 10% compared to the case where the liquid delivery hose is connected near the nozzle at the tip of the swing guide vane assembly. This is because, when the liquid transfer hose is connected near the nozzle at the tip of the swing guide vane assembly, the liquid injection nozzle protrudes into the tubular body of the assembly, which causes the flow of blowing air to be inhibited.

In addition, the present invention can automatically adjust the liquid spraying amount by adjusting the engine rotation speed, and can be easily moved up and down or left and right by the use of the reducer, thereby maximizing the convenience of use, etc. It works.
