Description

[Detailed description of the invention] This invention relates to a device for spraying herbal medicines for agriculture, horticulture, or epidemic prevention, such as fungicides, insecticides, herbicides, and fertilizers. The present invention aims to provide a device that uses the pressure of pressurized gas to eject and spray a drug.

Conventionally, various types of spraying devices for this kind of medicine have been put to practical use, but they can be roughly divided into those that rely on input and those that rely on power.

Manual sprayers carry the entire chemical tank on your shoulder or back and spray, and most require you to use one hand to move the handle without spraying evenly, and use the other hand to spray evenly. Since the direction of the spray nozzle for spraying is moved evenly around the surrounding area, it is difficult to keep the rotational speed of the handle constant at all times, which tends to cause uneven spraying and, above all, causes severe worker fatigue.

On the other hand, power-powered devices do not consume energy for spraying, and some are relatively small and simple to carry on one's back. The problem is that it can damage your health.

The present invention aims to improve the drawbacks of the conventional devices, and aims to provide a relatively small nebulizer that is easy to carry and use, and which is stored in the cap of the drug container. Since the medicine is ejected by the pressure of gas stored in a pressurized gas cylinder, there is no wastage of labor, no mechanical vibration, no noise, and no malfunctions occur.

In addition, since the spray pressure is kept constant, uniform spraying is possible.
Furthermore, since the pressurized gas cylinder is removably housed in a cartridge type, it has many advantages such as being easy to maintain and manage and being economical.

Hereinafter, the present invention will be explained in more detail based on the drawings showing typical examples.

The cap 1 of the drug container 2 includes a storage space 13 for a small gas cylinder 4, a drug ejection gas conduit 3 having an opening 11 at its tip,
A drug spray nozzle 9 having a built-in gas injection nozzle 8 is provided, and a piercing tool for a small gas cylinder is attached to the upper part of the drug spray nozzle 9.

First, a required amount of drug powder is put into the drug container 2, and the cap 1 is tightly attached via an O-ring, backing, etc. 16 as required.

Next, put the small gas cylinder 4 into the storage part of the cap 1, attach the cap 19 equipped with the magnet generating coil 5 containing the plunger 6 having the needle 7 which is retracted by the spring 17, and attach the O-ring as necessary. , backing etc. 15 to seal tightly.

After it is installed at a predetermined location, when the magnet generating coil 5 is energized from the outside, the plunger 6 is actuated to push down the needle 7 and puncture the small gas cylinder 4.

The gas ejected from the cylinder is transferred to the storage space 13 and the branch path 10.
The first part passes through the opening 11 at the tip of the drug ejection gas conduit 3.
The drug is ejected into the drug container, and the surrounding drug powder is stirred and entrained by the pressure, and the drug is sprayed into the air from the drug spray nozzle 9 through the flow path 14 provided in the cap.

The remaining branched gas is injected as it is from the gas injection nozzle, and serves to further effectively promote drug spraying.

Gas injection nozzles are usually formed concentrically within the drug spray nozzle, but their structure is not necessarily limited, and they may be provided separately as long as the suction force from the gas injection can be applied, or the entire cap The number of nozzles is not limited to one set, but two or more sets may be provided depending on the overall balance if necessary.

In addition, the specific structure of the device of the present invention is not necessarily limited to that illustrated in the drawings, and any type of structure may be used.

According to the spraying device of the present invention, labor consumption and
There is no mechanical vibration or noise, and it can be operated from a distance from the spraying site, which prevents the risk of inhalation of the drug by those involved in spraying.Additionally, if the electricity is turned on using a timer, it can be operated unattended at night. It is very labor-saving because the chemical can be sprayed in the same state, and in particular, in addition to simply spraying by gas entrainment, it also uses the separate gas injection energy, so it can be uniformly and effectively sprayed in a very short time. It has a number of excellent advantages, such as being able to be widely distributed, requiring less gas, and being economical and easy to use if liquefied gas is used.
