Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention belongs to the technical field related to a medicine spraying device.

[0002]

BACKGROUND OF THE INVENTION Aerosols (so-called spray cans) are widely used throughout the world as spraying devices for pesticides and home gardening agents. That is the biggest reason that the preparation of the drug solution is not required. The drawback of this aerosol is that it sprays out of small holes at high pressure, and depending on the solvent used to dissolve the active ingredient, the latent heat of vaporization is quickly taken away. Surface is quenched and suffers from frost injury. In order to avoid this cooling damage, slow-vaporizing solvents are used, of which water is the typical and probably the only practical one. Although water has a large latent heat, it does not cause cooling damage to leaves and flowers in practice due to slow evaporation rate, but it has one major disadvantage. It is very difficult to formulate aerosols because pesticides, such as insecticides and fungicides, which are mostly fat-soluble compounds, and home gardening agents are not soluble in the desired amount of water. When an active ingredient that does not dissolve in water is forcibly suspended in water, it often becomes clogged with a nozzle. Further, for example, when making a mixed chemical of an insecticide and a bactericide, even if one is an active ingredient that is soluble in water, the other is not necessarily the same as the active ingredient that is similarly soluble in water. It is very rare that both are soluble in water. The active ingredients of currently widely used pesticides are mostly aerosol spray concentrations (usually 1%).
% Is often used in ethanol for home gardening because it is soluble in ethanol (although often less than 10%). Ethanol is also safe for humans and animals, which is a major reason why it is widely used.

[0003] An object of the present invention is to provide an apparatus which can improve the cooling damage of an aerosol using ethanol or a similar non-aqueous solvent which does not harm plants such as flowers and leaves, thereby improving the workability of spraying chemicals. To provide.

FIG. 1 is a front view showing a first embodiment of the apparatus of the present invention, FIG. 2 is an enlarged front view of a grip portion of FIG. 1, and FIG. 3 is a length adjustment of a grip portion of a flexible tube in a second embodiment. FIG. 4 is a partially cutaway front view of the third embodiment, and FIG. 5 is an explanatory view showing a use form of the device of the present invention common to each embodiment.

A first embodiment of the present invention will be described in detail with reference to FIGS. Reference numeral 1 denotes an operation rod made of, for example, glass fiber having a total length of about 80 cm, and has a tip outer diameter of about 7.4.
mm and a hollow structure with a rear end outer diameter of about 10 mm. A spray nozzle 2 is mounted on the tip of the operating rod 1, and a grip 3 of about 10 cm having thermal insulation and moderate soft elasticity such as styrene foam is provided on the outer periphery of the rear end.
Is attached.

The length 4 is such that the spray nozzle does not spray the aerosol chemical solution at a minus temperature, more specifically, the necessary minimum length of about 350 obtained as a result of many experiments.
cm. This is a flexible tube made of polyethylene having a length of 1 cm, and the flexible tube 4 has a crush resistance. A part of the distal end of the flexible tube 4 is inserted into the operation rod 1, and the distal end of the flexible tube 4 is connected to the spray nozzle 2. Then, the middle part of the flexible tube 4 is pulled out to the outside from the through hole 5 provided in the operation rod 1 near the grip 3, and is spirally and closely wound around the entire length of the outer periphery of the grip 3 backward. The flexible tube 4 is inserted into the operation rod 1 again through the through hole 6 provided about 2 cm above the rear end of the operation rod 1 while forming the adjustment portion 4a. A play portion 4b is formed to guide the outside of the flexible tube 4 to a length of about 80 cm to facilitate the spraying operation, and is connected to the rear end of the flexible tube 4 constituting the play portion 4b so as to be detachable from the valve stem 7a of the aerosol can 7. The child 8 is attached.

As shown in FIGS. 1 and 2, the grip 3
In order to fix the length adjusting portion 4a of the flexible tube 4 having the spiral structure provided in the above, a tube made of a heat-shrinkable thin synthetic resin material was put on the grip, and heat was applied thereto to shrink the tube. The shrink structure coating 9 is adhered. Also, instead of the coating 9, a resin tape (not shown) is wound,
Since the length adjusting section 4a may be fixed, it is not limited to the illustrated one. A relatively wide finger contact portion 8a for contacting the fingertip is integrally formed on the upper portion of the connector 8, so that it can withstand a pressing action for several tens of seconds.

Next, the configuration of the second embodiment will be described with reference to FIG. 3. In this embodiment, the length adjusting portion 4a of the flexible tube 4 formed on the grip 3 is parallel to the axis of the grip 3. Further, the grip 3 is wound in a meandering shape over substantially the entire length. The other configuration is completely the same as the structure of the first embodiment, so that illustration and detailed description are omitted.

The configuration of the third embodiment will be described with reference to FIG. This embodiment differs from the first and second embodiments in that a hollow operating rod made of glass fiber is not used. That is, the long flexible tube 10 having a length that does not allow the spray nozzle to spray the aerosol chemical liquid at a minus temperature is densely spirally wound and connected to form the operation rod 11 having a hollow structure. This operating rod 11 corresponds to the length adjusting section 4a of the flexible tube 4 in the first and second embodiments. A spray nozzle 1 in which the tip of the flexible tube 10 is attached to the tip of an operation rod 11
2 and a grip 13 is attached to the rear end of the operating rod 11. The flexible tube 10 is wound tightly around the entire length of the grip 13 in a spiral manner. And another length adjusting portion 10a is formed on the grip 13 portion.

The means for forming the operating rod 11 by a spiral flexible tube 10 is such that the flexible tube 10 is densely spirally wound around a tapered thin rod (not shown), and this winding is performed. For example, a synthetic resin-based adhesive is applied to the formed surface, and the spiral flexible tubes 10 are joined together, or a thin tube made of a thin synthetic resin material having heat shrinkability is covered, and heat is applied thereto. In addition, a contracted shrink-structure coating (not shown) is adhered to form the operation rod 11 having rigidity and moderate flexibility. Also, a coating 14 having a shrink structure similar to that of the first embodiment is formed on the surface of the length adjusting portion 10a of the grip 13 portion.

In the third embodiment shown in FIG. 4, the main part is constituted only by a spiral-structured operating rod 11 to which a spray nozzle 12 is attached, and a flexible tube 10 connected to the rear end of the operating rod 11 is connected. The connector according to claim 3, wherein a connector detachably attached to the valve stem of the aerosol can is connected to the rear end of the play portion 10b, and the flexible tube 10 is meandering parallel to the axis of the grip 13. The invention includes the configuration of the wound claim 5.

FIG. 5 shows a use state of the apparatus of the present invention. Reference numeral 15 shown in the figure denotes a cloth holder.
A cylindrical portion 15a on which the aerosol can 7 is fitted and supported vertically is provided at the center of the holder. The holder 15 is provided with a waist belt 16 in a horizontal position and a shoulder belt 17 for hanging the holder 15 on a shoulder. The aerosol can 7 can be attached to fit the human body as shown in the figure.
Is fixed to the human body. In this state, the operator can hold the base of the operation rod 1 or 11 with the right hand, press the connector 8 with the thumb of the left hand, and spray the medicine continuously from the spray nozzle 2 for a desired time. Thus, the aerosol can 7 is attached to the holder 1
Since the connector 5 is fixed to the waist, the pressing action of the connector 8 is stabilized, and the spraying operation can be performed easily.

The chemicals used as aerosol cans include, for example, insecticides, fungicides, plant growth regulators, fungicides, herbicides, termite killers, fertilizers, and the like.

[0015]

[Description of operation] The length of the flexible tube is about 180cm.
And a flexible tube with a length of about 350
aerosol cans containing an alcoholic solution containing 0.1% of the insecticidal component isoxathion together with a propellant LPG were connected to the control and the device of the present invention using a device of the present invention having a diameter of 17 cm. Injecting continuously for 30 seconds while keeping the bottom of the alcohol thermometer at a distance of 10 cm from the nozzle, 0.5, 10, 15, 20, 25
And the temperature at 30 seconds was recorded, as shown in Table 1.

[Table 1] The same experiment as above was carried out, and the same experiment was conducted in another place at another place in a space having an outdoor temperature of 13 ° C on the other day, as shown in Table 2.

As is clear from Tables 1 and 2, it is shown that the present invention can practically sufficiently prevent plant cool damage. That is, in Table 1, in the present invention, the surface temperature of the object to be sprayed does not become 0 ° C. or lower with respect to the continuous injection for 30 seconds, but in the control, the spraying temperature of about 15 seconds already drops to a temperature close to 0 ° C. After 5 seconds, the temperature drops to 2 ° C below freezing, and the temperature continues to decrease. On the other hand, in the present invention, the temperature is kept at 3 ° C. even after 30 seconds, and the time for continuous injection is practically usually longer than 30 seconds. . Table 2 is made under completely different temperature conditions, but the difference between the control and the present invention is as remarkable as the result of Table 1, clearly demonstrating the superiority of the present invention. It is obvious from the fact that plants are almost composed of water that the surface temperature of plants is below freezing, but it is extremely bad for plants, and the apparatus of the present invention is used. Since there is no such thing at all, it is very significant to be able to control pests and so on with confidence.

[0016]

According to the configuration of the present invention as described above,
The following effects can be obtained. (A) Common to each claim, the length of the flexible tube connecting the aerosol can and the spray nozzle is set to a length such that the spray nozzle does not spray the aerosol chemical solution at a minus temperature, more specifically, a length of about 350 cm. As shown in Tables 1 and 2, about 3
Even if it is continuously sprayed for 0 seconds, a chemical solution of about 3 ° C and 4 ° C is sprayed,
The surface of the object to be sprayed, such as flowers and leaves, is quenched, free from frost injury, and the pests can be safely controlled. (B) A flexible tube connecting the rear end of the operating rod and the aerosol can, commonly about 80 cm.
About 200 cm of the remaining about 270 cm flexible tube excluding the length of the flexible tube inserted into the long operating rod
However, since the absorption process is performed by the length adjustment unit wound on the grip unit, the operation rod can be scattered smoothly, and the surplus flexible tube interferes with other objects to prevent the operation from the aerosol can or the spray nozzle. Can be prevented rationally, and the efficiency of spraying the medicine can be improved. (C) Since the length adjusting portion of the flexible tube is formed in the grip portion as common to the third to seventh aspects, by grasping this length adjusting portion by hand, the spray medicine flowing through the portion is added by the body temperature. It can be warmed, has an attendant effect that can further prevent frost injury of sprayed objects such as flowers and leaves, and has a great economic effect, such as a reduction in the length of the flexible tube. (D) Since the aerosol can is attached and fixed to the waist of the human body, continuous pressing operation of the valve stem via the connector can be easily performed, and the efficiency of dispersing the medicine can be improved.
