Description

[Detailed description of the invention] (a) Industrial application field This invention is a waterproofing, insect repellent, and antibacterial liquid that quickly hardens when mixed with water (more precisely, it hardens when mixed with water). This refers to a chemical solution containing resin, such as a termite repellent (for simplicity, this is simply referred to as an insect repellent solution) and is sprayed out separately and automatically and continuously. The present invention relates to a method and apparatus for spraying an insect repellent liquid that can be atomized and mixed outside a container before being sprayed.

(b) Prior Art The soil under the floors of houses is extremely moist. Therefore, it is the perfect environment for termites and wood-decaying fungi to breed.

Therefore, various insect repellent liquids have been developed that penetrate into the soil and block its pores, thereby blocking the movement of ant larvae, decay fungi, and water.

For example, those disclosed in Japanese Patent Application Laid-open No. 59-55940 are similar, but most of these are liquids containing resin as a component and used by dissolving this in a solvent.

This is also the case with the insect repellent liquid used in this invention, which is a mixture of water and resin liquid at a ratio of 7:1, but what these insect repellent liquids have in common is that they harden very quickly.

Therefore, if applied in a pre-mixed state,
It hardens before the work is finished, rendering it useless. Additionally, if they are applied separately, they have the disadvantage that they cannot be mixed or atomized properly.

For this reason, in Japanese Patent Publication No. 36-686, there is a device in which water and insect repellent liquid are jetted out at the same time, and the liquid is stirred and mixed in between.

(c) Problems to be solved by the invention However, the above-mentioned prior art simply wraps the two liquids in a layer and attempts to stir it by blowing air around it, so its stirring ability is weak. .

The present invention solves these problems by ejecting two liquids in concentric layers and further colliding the first liquid in a cross-collision manner in front, thereby increasing the stirring ability.

(d) Means for Solving the Problem Under this objective, the present invention provides a method for spraying water and a waterproof, insect-proof, and anti-bacterial liquid that hardens when mixed with water. , a waterproof, insect-proof, and anti-bacterial liquid characterized by ejecting the anti-bacterial liquid in a concentrically confined state, and further cross-colliding a part of this water from outside the water to atomize and mix. The spraying method and the arrangement of water spouts that spout water concentrically and backwards around the insect repellent fluid spout that spouts waterproof, insect repellent, and antibacterial fluid that hardens when mixed with water. , a waterproofing and insect-proofing device characterized in that a vertical water spout is provided in front of the water spout, which intersects with the axis of the water spout from above and below at a certain angle and guides and spouts a portion of the water. The above-mentioned problems were addressed by providing antibacterial liquid spraying devices.

(e) Effect With the above configuration, the insect repellent liquid is wrapped in water and ejected in a concentric cylindrical shape, and a part of this water is ejected in a cross-colliding manner at the front, resulting in atomized mixture. The degree of

(f) Examples Hereinafter, specific examples of the spraying method and the spraying device according to the present invention will be described with reference to the drawings.

As shown in Fig. 1, this spraying device consists of water 1
and the insect repellent liquid 2, which hardens by mixing with water 1 at a certain ratio, are separately jetted out, and the water 1 and the insect repellent liquid 2 are made to cross-collide, atomized, and evenly mixed to form a fan-shaped jet. It forms a pattern and is composed of a water introduction path 3, an insect repellent liquid introduction path 4, a sprayer 5, and the like.

As the insect repellent liquid 2, for example, a waterproof ant-repellent resin liquid mixed with a certain type of insecticidal ingredient, which starts to harden in about 3 minutes from the time of mixing, is used when mixed at a ratio of 1 part to 7 parts of water. .

The water introduction path 3 controls water 1 supplied under pressure from a water supply source 6 to a desired pressure via a water pressure reducing valve 7 that can be operated to reduce the pressure, and connects the water supply hose 8 to a rear connection port of the spout 5. It leads to 9. Water supply source 6
Generally, water taps are used that allow pressurized water 1 to be taken directly from the faucet, but water is taken out from a water storage tank (not shown) through a pump (not shown). may also be used.

The insect repellent liquid introduction path 4 controls the insect repellent liquid 2, which is sold in a one-ton can 10, to a desired pressure using a pressurizing device 11, a pressure tank 12, etc., and guides it to the front connection port 13 of the sprayer 5. It is something.

The pressurizing device 11 may be any device as long as it can control the pressure inside the pressure feeding tank 12, and in the illustrated example, the pressurizing device 11 can control the pressure inside the pressurizing tank 12.
The pressure inside the pressure feeding tank 12 is controlled to a desired pressure via a gas on-off valve 15 that can be opened and closed manually, a gas pressure reducing valve 16 that can be adjusted to reduce the pressure, a pressurizing hose 17, and the like. By using the nitrogen gas cylinder 14 in this way, it is possible to easily obtain high-pressure nitrogen gas that has a dew point under pressure of -60°C and is difficult to react with water, is harmless and safe, and has the advantage that a power source such as a compressor is not required. There is.

The pressure tank 12 has a removable airtight lid 1 on the top.
8, and by removing this airtight lid 18, the one-ton can 10 containing two insect repellent liquids can be stored inside as it is. At the same time, a connecting portion 20 for connecting the pressurizing hose 17 of the pressurizing device 11 is attached. The pressure pipe 19 is inserted through the upper outlet of the can 10 to the vicinity of its bottom surface, and its outward protrusion is connected to the front connection port 13 of the ejector 5 by a pressure hose 21 . Furthermore, the pressure tank 12 is equipped with an air vent opening that can be opened and closed manually so that the air that has entered the interior by opening and closing the airtight lid 18 is released to the outside by nitrogen gas that is sent inside from the pressurizing device 11. A lower end portion of an air vent hose 23 having a valve 22 provided thereon is attached to the bottom wall of the pressure-feeding tank 12 in a penetrating manner.

The ejector 5 is preferably in the shape of a long-handled spray gun that can be operated with one hand, and has a rear connection port 9 connected to the water supply hose 8 of the water introduction path 3 near the grip portion 24;
A front connection port 13 is provided which connects to the pressure feed hose 21 of the insect repellent liquid introduction path 4, and the water 1 and the insect repellent liquid 2 flow from both connection ports 9 and 13 through separate guide paths 25 and 26 formed inside. Then, the water spout 27 at the front end of the protrusion
and insect repellent liquid spout 28, and on-off valves 29 and 30 for water and liquid are incorporated in the middle of both guide paths 25 and 26, respectively. In this case, the opening/closing valves 29 and 30 are opened in the opening direction against the springs 32 and 33 only when the swingable lever 31 is pulled backwards. .

As shown in FIGS. 1 and 2, the insect repellent liquid spout 28 is a spout for spouting the insect repellent liquid 2, and is formed in the front-rear direction at the center of the protruding front end of the ejector 5.
One of the water spouts 27, cylindrical spout 27a, is
The other water and waste water spout 27b is formed in a cylindrical shape concentric with the insect repellent liquid spout 28, and is positioned slightly forward and upward of the insect repellent liquid spout 28, and its spouting direction is the same as that of the insect repellent liquid spout 28. 28 so as to cross and collide with each other at a constant angle. Note that the insect repellent liquid spout 28 is the cylindrical water spout 2.
It is preferable to form it so as to protrude forward by δ (specifically, about 1 to 3 mm) from 7a, which has the advantage of preventing the insect repellent liquid 2 and water 1 from reacting inside the sprayer 5. .

Further, 34 is an adjustment hole into which a threaded shaft (not shown) serving as a flow rate adjustment valve provided in the liquid guide path 25 is inserted. By adjusting the flow rate, it is possible to adjust the amount of water 1 flowing through this area, and accordingly, both the spout ports 27 and 28 configured with the insect repellent liquid 2 can be adjusted.
It is possible to change the pattern of eruptions from the

In addition, 35 is a water pressure gauge that measures the water pressure on the secondary side reduced by the water pressure reducing valve 7; 36;
37 is a pressure gauge that measures the primary pressure and secondary pressure before and after the gas pressure reducing valve 7, and 38 is a liquid on-off valve 30.
This is an adjustment screw that can adjust the timing in the opening direction and the amount of ejection.

According to the above, first, 10 cans containing 2 insect repellent liquids.
Remove the top cover and store it in the pressure feeding tank 12,
The airtight lid 18 is tightly closed so that the pressure pipe 19 is inserted into the Hitto can 10. Then, open the water faucet and the gas on-off valve 15, and while watching the pressure gauges 35 to 37 of the water introduction path 3 and the pressurizing device 11, adjust the pressure to the set pressure according to the chart (not shown) created in advance. The pressure is adjusted by the respective pressure reducing valves 7 and 16. Through this pressure adjustment, the water 1 is directly brought to the set pressure, and the insect repellent liquid 2 is pushed against the liquid level in the canister 10 by the nitrogen gas pressure in the pressure tank 12, and passes through the pressure pipe 19, etc. to the sprayer 5. Double open/close valve 29,
30 separately, and after the water and insect repellent liquid are spouted from the openings 27 and 28 by opening both on-off valves 29 and 30, the mixing ratio of water 1 and insect repellent liquid 2 is 1:7, and the flow rate control system Can be made more cost-effective. In addition,
Before adjusting the pressure, the pressure of the nitrogen gas being fed into the pressure tank 12 forced the air that had accumulated inside the pressure tank 12 to escape to the outside by opening the air release on-off valve 22. After that, the insect repellent liquid 2 and the moisture in the air are prevented from reacting because the insect repellent liquid 2 is closed again.

Next, when the front end of the ejector 5 is directed toward the soil surface at the ejecting location and the lever 31 is pulled with a finger, the water and liquid on/off valves 29 and 30 are opened, and a portion of the water 1 and the insect repellent liquid 2 are released. Water is spouted concentrically from the cylindrical water spout 27a and the insect repellent fluid spout 28, and another part of the water is spouted from the upper and lower spout 27b, colliding crosswise, and repeating mutual shearing. Both ejected liquids (water 1 and insect repellent liquid 2) are atomized and mixed uniformly,
In addition, by operating the flow rate adjustment valve inserted into the adjustment hole 34 described above, the spray can be sprayed while forming a suitable fan-shaped spray pattern.
1 can be pulled and operated as it is to uniformly and easily spread the mixed solution on the soil surface.

However, if insect repellent liquid 2 runs out during spraying,
Stop pulling the lever 31 and close the water/liquid on/off valve 2.
9 and 30 are closed, the empty can 10 in the pressure feeding tank 12 is taken out, another can filled with insect repellent 2 is stored, and the spraying operation can be continued again in the same manner as described above. After the spraying work is completed, in particular, the pressure pipe 19, which is the passage for the insect repellent liquid 2, the pressure feed hose 21, and the guide path 2.
6. The liquid spout 28 can also be easily cleaned by taking out the Itto can 10 from the pressure feeding tank 12, storing the cleaning liquid can, and flowing the cleaning liquid into this passage in the same manner as the above-mentioned spraying operation. . It should be noted that the can 10 in which the waterproof and insect repellent liquid 2 remains can be stored for a long period of time by filling it with nitrogen gas and sealing it tightly.

(g) Effects of the invention As is clear from the above explanation, this invention has the following effects:
The water 1 and the insect repellent liquid 2 sent from the water introduction path 3 and the insect repellent liquid introduction path 4 are separately guided into the inside of the squirt device 5, and from at least one pair of opposing spout ports 27 and 28 of the ejector 5. Water 1 and insect repellent liquid 2 are automatically and continuously spouted by an insect repellent liquid spraying method and device in which water 1 and insect repellent liquid 2 are sprayed while cross-colliding and atomized and mixed. It can be mixed and sprayed, has better atomization mixing ability than conventional products, improves spraying accuracy, and significantly improves work efficiency.

Further, since the water 1 and the insect repellent liquid 2 are mixed outside the container, the two liquids are not mixed and hardened inside the container, making cleaning easier.
