In general, livestock farms, warehouses or odor facilities are sprayed with liquid insecticides to kill flies, mosquitoes, moths, wasps, worms, ants, etc., or are generated from flower gardens, horticultural parks or plastic houses. The insecticide is also sprayed to prevent hatching of worms and larvae.

In response to this reality, with the technology developed as a device that can spray the insecticide

There is a portable nebulizer of Republic of Korea Patent Application Publication No. 98-8338, which will be described with reference to FIG.

As shown, the portable nebulizer according to the prior art includes a battery 20 embedded in a battery case; A drug composed of a main body 5, an injection port 2 for injecting a medicine, etc., a tube 3 connected to the sprayer 10, and a hose 4 for supplying a medicine and the like to the sprayer 10. A tank 1; A suction cover 11 located at the rear and inhaling air, a motor 12 connected to the battery 20, a fan 13 driven by the motor 12 to generate strong air, and a chemical tank It consists of the check valve 14 fastened to the tube 3 of (1), and the nozzle 15 fastened to the hose 4. As shown in FIG.

Referring to the operation of the portable sprayer according to the prior art configured as described above are as follows.

First, when a switch (not shown) is operated, the motor 12 drives the fan 13 to generate air, and a part of the generated air passes through the tube 3 through the check valve 14 to the chemical tank 1. ) Is introduced into the inside of the drug tank 1 to generate pressure. The medicine or the like is sprayed through the nozzle 15 of the sprayer 10 via the hose 4 by the pressure of the air. At this time, the air generated in the fan 13 sprays the sprayed medicament more strongly through the nozzle hole 16.

However, the prior art configured as described above has the following problems.

First, since the means for generating air is only a two-lobed fan 13 which is commonly used, as shown in FIG. 2, as the fan 13 rotates, the outside air is sucked in and ejected. At the time, the velocity diagram (V) gradually increased in ejection than the inhalation of air, whereas the pressure diagram (P) was almost identical to the inhalation and ejection of air. Because of this, the fan 13 which is rotated by receiving the driving force of the motor 12 is discharged through the nozzle hole 16 through the nozzle 15 in a state where the increase in air pressure is limited and the flow rate of the inflowing air is fast. In addition, the drug discharged through the nozzle 15 has a problem that the discharge rate is increased only through the nozzle hole 16 in the atomized state.

In addition, when the rotation speed of the motor 12 is increased, the drug can be sprayed to a long distance through the nozzle hole 16, but a lot of noise is generated due to the fan 13 rotating at a high speed, whereas the motor 12 Reducing the number of rotation of the noise generated from the fan 13 is rotated at a low speed can be reduced, but there was also a problem that can only spray the drug to the local area through the nozzle hole (16).

In addition, when the motor 12 is rotated at a high speed in order to spray the drug to a long distance, there is a problem that the power consumption is increased to shorten the service life of the battery.

The present invention has been made to solve the above problems, by compressing and transporting the air sucked from the outside, so that the sprayed in the atomized state when sprayed through the nozzle irrespective of the spraying distance of the medicine contained in the medicine container and An object of the present invention is to provide a portable insecticide biospray machine which does not need to increase the rotational speed of a motor which is a driving source for compressing air at high speed.

Referring to the action of the portable insecticide biospray machine according to the present invention configured as described above are as follows.

First, after the power cord 55 is connected to a power source, when the on / off combined motor rotational speed adjustment switch 56 is turned on, power is applied to the motor 70 and starts to be driven.

When the motor 70 starts to be driven, the rotary shaft 71 is rotated to rotate the impellers 72 and 73 and the diffuser 74.

As described above, when the impellers 72 and 73 and the diffuser 74 begin to rotate, the air outside the main body 50 begins to be sucked into the air inlet 51 through the air intake grill 51a.

As described above, the air sucked into the main body 50 is first introduced through the air inlet hole 72b 'formed in the second disc 72b of the impeller 72, and the air thus introduced is centrifugal of the impeller 72. Because of the movement, it is guided between the plurality of vanes 72c and flows in an accelerated direction in its tip direction, ie the edge or radial direction.

The air that has gone through such a path increases the flow rate and simultaneously increases the pressure.

In addition, the air passing through the impeller 72 flows into the diffuser 74 while being rotated.

The air flowing into the diffuser 74 is reduced in speed, but the pressure is further increased.

As described above, the air elevated in the diffuser 74 exits the diffuser 74 by the guide of the blade 74b constituting the diffuser 74 and flows back into the impeller 73 to be compressed once more.

Here, the path of the air moving into the impeller 73 is the same as the path of the impeller 72 will be omitted.

Thus, the air compressed by the diffuser 74 and the impeller 73 twice flows along the flow path 53 in the main body 50 while maintaining the speed and the pressure rise state when exiting the impeller 73. 52) to the side.

At this time, since the nozzle 80 is provided on the jet port 52, the drug in the drug container 60 is moved along the drug lift pipe 61 by the speed of the compressed air passing through the jet port 52. Sucking up and ejecting from the nozzle 80 is sprayed to the outside of the main body 50 through the ejection opening (52).

As described above, the drug ejected through the ejection opening 52 is ejected in an atomized state.

On the other hand, when the spraying distance of the chemical agent is changed from the short distance to the long distance, if necessary to increase the output of the motor 70 by operating the on / off combined motor motor rotational speed adjustment switch 56, according to the process as described above The air passes through the jet port 52 at a high speed in a high pressure state, and thus the drug is sprayed from the nozzle 80 to move to the atomized state with the air to a far distance.

On the other hand, in the embodiment of the present invention, when the spray amount of the drug sprayed from the ejection opening 52 of the main body 50 or the spray condition is not very good, the control rod 92 is rotated appropriately to move the nozzle 80. It is also possible to make the passage 81 open to an appropriate value.

As described above, according to the present invention, by compressing and transporting the air sucked from the outside, regardless of the spraying distance of the drug contained in the medicine container, sprayed in the atomized state when sprayed through the nozzle and driving to compress the air Cause This provides an effect of not having to increase the rotational speed of the motor at high speed.
