Japanese Patent No. 5586802

  By the way, in this conventional pest control apparatus, since a heat medium is hot water, there existed a problem that hot water fell and soiled the circumference | surroundings. In addition, since a pump for supplying hot water must be provided, the weight of the carriage increases and the size of the carriage increases, which makes it difficult to carry the carriage and impairs workability. It was. In particular, when the pump is electric and the heat source is an electric heating type, electric wiring is required, and in a place where the work space is small, there is a place where the carriage cannot be installed, and the versatility is poor.

  The present invention has been made in view of such problems, and uses a heat medium that does not pollute the surroundings as much as possible as a heat medium, and also facilitates carrying of the part that generates the heat medium, thereby improving workability. It is an object of the present invention to provide a pest control apparatus that improves versatility.

  In order to achieve such an object, the pest control apparatus of the present invention is a device according to claim 1, wherein the tank stores water and contains a pyrogen that generates heat vapor by reacting exothermically with the water; A discharge port portion provided in the tank for discharging water vapor in the tank, a flexible hose connected to the discharge port portion at one end, and spraying water vapor toward a pest connected to the other end of the hose It is set as the structure provided with the possible water vapor ejector.

  As the exothermic substance, for example, inorganic salts such as calcium chloride, magnesium chloride, calcium oxide (quick lime), magnesium oxide, and zeolite can be used. Two or more of these can be selected and used in combination. Further, for example, an additive such as aluminum may be used. The exothermic substance is not limited to these, but a substance that does not generate harmful substances as much as possible is preferable.

  When the water vapor is discharged, the water vapor is gradually cooled to lower the temperature, and a part of the water vapor is phase-transformed into water droplets. And when it injects | emits in air | atmosphere through a water vapor | steam injection body, water vapor | steam will expand | swell further and will reduce pressure and temperature fall. Thereby, the water vapor sprayed to the outside becomes a wet gas that is higher in temperature than the outside air, saturated water vapor, and contains water droplets (steam). Since the amount of water sprayed is very small compared to a device for spraying hot water, the object is not excessively wetted.

When using this pest control device, first put a pyrogen and water into the tank. As a result, the exothermic substance reacts exothermically with water to generate water vapor. The generated water vapor is discharged from the discharge port, and water vapor is jetted from the water vapor jet through the hose. By operating this water vapor spray body and spraying water vapor toward the pest, the pest can be killed.
In this case, water vapor can be generated as a heat medium simply by putting a heat-generating substance and water in the tank, so that the heat medium can be generated very easily. And since a heat medium is water vapor | steam, the situation which falls down like the conventional hot water and stains the circumference | surroundings can be prevented. In addition, since the part that generates water vapor is a tank, there is no heavy object such as a pump and no electrical wiring, so it can be made portable, and it is easy to carry and can greatly improve workability. .
Further, since there is no heavy object such as a pump or electric wiring, it can be easily transported to a place where the work space is narrow, and the versatility can be improved accordingly.

  When the exothermic reaction between the exothermic substance and water ends, the generation of water vapor can be continued by placing a new exothermic substance or water into the tank. When the pest control is finished, the pyrogen and water are taken out from the tank and then prepared.

Furthermore, the invention of claim 4 is configured such that the tank includes a portable portion for carrying the tank. As a portable part, it can be comprised by the handle for holding a tank, the shoulder strap which attaches a tank to a body, etc., for example.
Thereby, since the operator can operate the water vapor ejector while carrying the tank, the worker can easily move according to the state of the pest, and the workability can be improved accordingly.

Further, the invention of claim 5 includes a nozzle having an injection port for injecting water vapor, and a main body having a water vapor passage for supporting the nozzle and reaching the nozzle and having a gripping portion. It is prepared and configured.
Thereby, since the water vapor ejector can be operated by grasping the grip portion, the operability of the water vapor ejector can be improved accordingly.

Furthermore, the invention of claim 6 is provided with an opening / closing mechanism for opening / closing the passage in the main body, and the internal pressure of the tank is set to a predetermined level or more when the opening / closing mechanism closes the passage in the tank. In this case, a relief valve is provided for releasing the water vapor in the tank to the outside.
Thereby, water vapor | steam can be sprayed with respect to a pest or can be stopped by operation of an opening-and-closing mechanism. Therefore, water vapor is not unnecessarily jetted, and steam can be jetted in accordance with pest conditions and nest conditions, so that operability can be improved accordingly. Even when the water vapor injection is stopped, even if the pressure in the tank increases, the water vapor can escape from the relief valve and the pressure in the tank can be maintained at a constant pressure, so that safety can be achieved.

Furthermore, the invention of claim 7 is configured such that the nozzle is formed in a tubular shape and a plurality of the injection ports are provided on the outer periphery of the nozzle.
Thereby, since a plurality of water vapor injection ports are provided on the outer periphery of the nozzle, the water vapor can be dispersed and injected along the axial direction of the nozzle. For example, this is extremely effective when a nozzle is inserted into the beehive to kill the bee.

  According to the present invention, the pest control apparatus can generate steam as a heat medium only by putting a heat-generating substance and water in the tank. Therefore, the heat medium can be generated very easily. It can be carried out. And since a heat medium is water vapor | steam, the situation which falls down like the conventional hot water and stains the circumference | surroundings can be prevented. In addition, since the part that generates water vapor is a tank, there is no heavy object such as a pump and no electrical wiring, so it can be made portable, and it is easy to carry and can greatly improve workability. .

As the exothermic substance H, for example, inorganic salts such as calcium chloride, magnesium chloride, calcium oxide (quick lime), magnesium oxide, and zeolite can be used. Two or more of these can be selected and used in combination. The exothermic substance H is formed in a granular material. Further, for example, an additive such as aluminum may be used.
This exothermic substance H is stored in a storage bag F that is formed in a size that can be stored in the tank 10 and that is formed of a sheet material through which water W can pass. Since it is stored in the storage bag F, it becomes easy to handle and carry.
In the embodiment, for example, a Morian heat pack (registered trademark: manufactured by Kyodo Co., Ltd.) mainly composed of calcium oxide (quick lime) and aluminum powder is used. Although the operating time per bag is about 7 minutes, water vapor can be sufficiently generated. If necessary, two or more bags can be used, or they can be added sequentially.

The tank 10 is a portable type, and includes a heat insulating container 12 having an opening 11 into which the storage bag F can be taken in and out, and a heat insulating lid 13 that opens and closes the opening 11 of the container 12 and seals the container 12 when closed. It is prepared for.
In the embodiment, as shown in FIG. 2, the container 12 is formed in a rectangular box shape having an opening 11 on the upper side, an outer wall 14 formed of a hard resin such as polyethylene, and a hard heat resistant resin such as polypropylene. It is formed by interposing a heat insulating material 16 such as polyurethane between the inner wall 15 formed in (1).

A heat insulating material 16 such as polyurethane is interposed between the wall 15 and the wall 15. The lid 13 is connected to the container 12 via a hinge 17 and is locked by a known lock mechanism 18 when closed.

  Further, the tank 10 is provided with a portable unit 19 for carrying the tank 10. The portable unit 19 can be configured by, for example, a handle for holding the tank 10 or a shoulder strap for attaching the tank 10 to the body. In embodiment, it comprised with the shoulder strap spanned across the container 12 right and left.

  A discharge port portion 20 that discharges water vapor in the tank 10 is provided on one side of the tank 10. The discharge port portion 20 is configured by fastening a tubular discharge tube 21 penetrating the wall portion of the container 12 and having an external thread formed on the outside with nuts 22 from both sides. One end of a flexible and heat-insulating hose 23 is fitted into and connected to a portion of the discharge port 20 that protrudes outside the discharge pipe 21.

  The water vapor jet body 30 is formed in a gun shape, and supports the nozzle 31 having a jet port 32 through which water vapor is jetted and the nozzle 31 via an elongated heat-insulating connecting pipe 33 to reach the nozzle 31. And a main body 36 having a gripping portion 35. As shown in FIG. 3, the nozzle 31 is formed in a tubular shape, and a plurality of injection ports 32 are arranged in rows and columns on the outer periphery at intervals.

Further, in the main body 36 of the water vapor ejector 30, as shown in FIG. 4, an adapter 37 that projects from the grip portion 35 and is connected to the passage 34 and is connected to the hose 23 is provided. Further, the main body 36 is provided with an opening / closing mechanism 40 for opening and closing the passage 34.
The opening / closing mechanism 40 presses the piston 41 against the biasing force of the coil spring 42, the coil spring 42 that constantly biases the piston 41 toward the side that closes the passage 34, and the piston 41 that opens and closes the passage 34. A rotatable trigger 43 that opens the passage 34 is provided. In FIG. 4, reference numeral 44 denotes a needle valve mechanism that adjusts the flow rate of water vapor by changing the opening of the passage 34.

In relation to the opening / closing mechanism 40, the tank 10 has a relief valve for releasing the water vapor in the tank 10 to the outside when the internal pressure in the tank 10 exceeds a predetermined level when the opening / closing mechanism 40 closes the passage 34. 45 is provided.
As the relief valve 45, a well-known valve is used, and although not clearly shown in FIG. 2, for example, a ball valve penetrating the wall of the container 12 and having an external thread formed outside and biased by a coil spring is provided. And is secured by nuts 46 from both sides of the wall of the container 12. The biasing force of the coil spring can be adjusted.

  Therefore, when the pest control apparatus S according to this embodiment is used, the following is performed. Here, as shown in FIG. 5, a case where a hornet as a pest is exterminated in its nest N will be described. In general, bees such as wasps can be killed at temperatures of 46 ° C. or higher.

First, as shown in FIG. 1, the lid 13 of the tank 10 is opened, the storage bag F containing the heat generating material H and the water W are put into the container 12, and the lid 13 is closed as shown in FIG. Since the exothermic substance H is stored in the storage bag F, it is easy to handle and easy to put in the container 12. Thereby, in the tank 10, the exothermic substance H reacts exothermically with the water W to generate water vapor.
In this case, since the water vapor can be generated as the heat medium simply by putting the exothermic substance H and water W into the tank 10, the heat medium can be generated very easily. The generated water vapor can be ejected from the water vapor ejector 30 through the discharge port portion 20 and the hose 23.

In this state, as shown in FIG. 5, the shoulder strap as the portable unit 19 is hung on the shoulder, the tank 10 is held, the grip portion 35 of the main body 36 of the water vapor sprayer 30 is gripped, and the honeycomb N is present. Move and position the nozzle 31 around the bee, or insert the nozzle 31 into the honeycomb N and pull the trigger 43. Thereby, water vapor | steam is injected from the water vapor | steam injection body 30, and a bee is killed.
In this case, in the nozzle 31, since the water vapor can be injected from the plurality of injection ports 32 provided on the outer periphery of the nozzle 31, the water vapor can be dispersed and injected along the axial direction of the nozzle 31. The killing property of bees can be improved.

Moreover, since the exothermic substance H and the water W put in the tank 10 are sealed, water vapor can be efficiently discharged from the discharge port portion 20. Furthermore, since the container 12 and the lid 13 insulate the inside, the temperature of the water vapor can be kept high. Furthermore, since the water vapor ejector 30 can be operated by grasping the grasping portion 35, the operability of the water vapor ejector 30 can be improved accordingly.
Further, since the portion that generates water vapor is the tank 10, since there is no heavy object such as a pump or electrical wiring, it is easy to carry and the workability can be greatly improved. Furthermore, since there is no heavy object such as a pump or electric wiring, it can be easily transported to a place where the work space is narrow, and the versatility can be improved accordingly. Furthermore, since the tank 10 is provided with a shoulder strap as the portable unit 19, the operator can operate the water vapor ejector 30 while carrying the tank 10, so that it becomes easy to move according to the situation of the honeycomb N. Workability can be improved.

In the operation of the water vapor ejector 30, the water vapor can be injected or stopped to the bees or the honeycomb N by the operation of the trigger 43. Therefore, water vapor is not unnecessarily jetted, and steam can be jetted in accordance with pest conditions and nest conditions, so that operability can be improved accordingly.
Since the water vapor escapes from the relief valve 45 even when the pressure in the tank 10 increases when the water vapor injection is stopped, the pressure in the tank 10 can be maintained at a constant pressure, so that safety is achieved. In addition, since water is injected from the nozzle 31 because it is water vapor, the amount of water is extremely small, so that it is possible to prevent a situation in which the water drops down like conventional hot water and pollutes the surroundings.

  When the exothermic reaction between the exothermic substance H and the water W ends, the generation of water vapor can be continued by putting the storage bag F or the water W containing the new exothermic substance H into the tank 10. Further, when the pest control is finished, the pyrogen H and water W are taken out from the tank 10 and prepared.

FIG. 6 shows another example of the water vapor jet body 30. The water vapor jet body 30 has a water jet jet 32 and a nozzle 31 formed in a multistage nested manner so as to be extendable and contractible, and a water vapor passage 34 that supports the nozzle 31 and reaches the nozzle 31 and a gripping portion. And a main body 36 having 35.
As shown in FIG. 3, the nozzle 31 is configured by providing a plurality of injection ports 32 on the outer periphery thereof. The main body 36 is configured by a telescopic hook-shaped tube body, and a base end portion is configured as a grip portion 35 having a trigger operation type opening / closing mechanism (not shown). The hose 23 is connected to the lower end of the grip part 35 via an adapter (not shown).

Therefore, according to the water vapor ejector 30, similarly to the above, the case where the hornet as a pest is extinguished in the nest N will be described. The shoulder strap as the portable unit 19 is hung on the shoulder and the tank 10 is held. Grasping the grasping portion 35 of the ejector 30 and moving it to the place where the honeycomb N is located, extending the spear-shaped main body 36, positioning the nozzle 31 around the bee, or inserting the nozzle 31 into the honeycomb N And operate the trigger.
Thereby, water vapor | steam is injected from the water vapor | steam injection body 30, and a bee is killed. In this case, since the main body 36 can be extended, it becomes easy to cope with the case where the honeycomb N is at a high place. Other actions and effects are the same as described above.

FIG. 7 shows another example of the tank 10. The tank 10 is formed in a so-called kettle shape. The tank 10 has a heat insulating container 12 having an opening 11 into which a storage bag F storing a heat generating substance H can be taken in and out, and a heat insulating container that opens and closes the opening 11 of the container 12 and seals the container 12 when closed. A lid 13 is provided. The container 12 is integrally formed with a discharge port 20 to which a hose 23 is connected, and the lid 13 is provided with a relief valve 45 similar to the above.
In addition, the container 12 is provided with a handle (handle) as the portable unit 19 for holding the tank 10. According to this, since the handle 10 can be held and the tank 10 can be held, the operator can operate the water vapor ejector 30 while carrying the tank 10, so that it becomes easy to move according to the situation of the honeycomb N, Therefore, workability can be improved. Other actions and effects are the same as described above.

In the above-described embodiment, the opening / closing mechanism 40 is configured by a mechanism including the trigger 43, but is not necessarily limited thereto, and is configured by a rotary valve that is provided in a faucet. It may be changed as appropriate. Moreover, in the said embodiment, although the vapor | steam injection body 30 was provided with the nozzle 31 and the main body 36 which has an opening / closing function, it was not necessarily limited to this, For example, the water vapor | steam injection body 30 is made into a nozzle. As in the conventional case, the hose 23 may be directly connected to the nozzle 31, and the hose 23 may be attached to a long hook. It doesn't matter.
Further, the configuration of the tank 10 is not limited to that described above, and may be changed as appropriate. For example, the lid 13 may be detachable from the container 12 by screw means. Moreover, it does not necessarily need to have heat insulation. Furthermore, the exothermic substance H is not limited to the above-described material, and an appropriate material may be selected.

  In the above embodiment, the case where the wasp is exterminated as a pest has been described. However, the target pest is not limited to the wasp, and it is a matter of course that various pests can be dealt with. In short, the present invention is not limited to the above-described embodiments, and those skilled in the art will make many changes to these illustrative embodiments without substantially departing from the novel teachings and advantages of the present invention. Many of these modifications are within the scope of the present invention.
