Description

  The present invention releases an insect repellent chemical gas to an air curtain that blocks the entrance and exit of a building in an air flow to form an insect repellent chemical gas-containing air curtain, and the insect repellent chemical gas-containing air curtain prevents insects from entering. The present invention relates to a method and apparatus for preventing insect invasion.

  Many techniques have already been implemented to prevent insects from entering with air curtains that block the entrances and exits of buildings. As an example, a door is provided at the entrance of a building, but even if this door is closed, if the illumination light inside the building is transparent to the outside, the transparent part of the door It is made up of an insect-proof translucent material that selectively absorbs light of a wavelength that can be perceived by insects, so that insects do not collect near the door, and an air curtain is blown from the top to the bottom of the doorway. By installing an air curtain device to be lowered, insects can be prevented from entering even when the door of the doorway is open (see, for example, Japanese Patent Laid-Open No. 10-225255).

  Furthermore, as an insect invasion prevention device using an air curtain, a shutter that opens and closes the entrance of a building is provided, and a pair of housings equipped with a blower inside are arranged on both front sides of the shutter. A trapping pit is provided on the partitioning floor, and further includes a control device for controlling the opening and closing of the shutter and the air flow blown out from the blower in the housing. The housing is connected to the air outlet and the outside provided on the surfaces facing each other. It is an air curtain device that has a suction port provided on the other surface that is open and forms an air curtain that blows out in the horizontal direction, and the air curtain device is moved by the control device to move the air curtain. The direction of the blowout was changed to prevent insects from entering even when the doorway shutter is open (for example, , See JP 2003-161489).

  On the other hand, using insect repellents to prevent the invasion of insects from entrances and exits with doors to buildings, a computer that performs processing, a pest control device using chemicals, and these are connected with a communication cable. Therefore, this pest control apparatus is designed to prevent insects from entering even when the doorway of the entrance / exit is opened by spraying a medicine according to a command from a computer (for example, Japanese Patent Application Laid-Open No. 2004-344045). See the official gazette).

(Example 1) which is a front view of the air curtain apparatus which comprises the insect intrusion prevention apparatus of FIG. It is sectional drawing of an air curtain apparatus (Example 1). (Example 1) which is the schematic of the electrostatic type chemical spraying apparatus which comprises the insect intrusion prevention apparatus of FIG. (Example 1) which is an operation | movement of the insect intrusion prevention apparatus in the state which opened the door of the entrance / exit of FIG. (Example 2) which is the schematic of the other electrostatic chemical spraying apparatus which comprises the insect intrusion prevention apparatus of FIG. It is sectional drawing of the state which installed the insect invasion prevention apparatus which shows other embodiment in the method of this invention in the entrance / exit of the building (Example 3).

  In the figure, an insect intrusion prevention device 1 includes an air curtain device 5 provided outside an entrance / exit 4 with an opening / closing door 3 of a building 2 and an electrostatic chemical spray for supplying an insect repellent chemical gas to the air curtain device 5. The apparatus 6 is configured.

  The air curtain device 5 includes an air inlet 11 and an air outlet 12 that blows out an air curtain in the airframe 10, and a blower 13 is disposed in the airframe 10 between the air inlet 11 and the air outlet 12. An insect repellent agent gas discharge port 14 is provided in the airframe 2 between the air outlet 13 and the blower outlet 12, and the insect repellent drug gas from the discharge port 14 is discharged into the air flow from the blower 13 and from the blower outlet 12. The air curtain is blown out to make an insect curtain containing gas.

  The airframe 10 is a flat box, and the suction port 11 is provided on the upper side of the front side surface 10a, and the air outlet 12 is provided on the bottom surface 10b. The interior of the machine body 10 is divided by a partition plate 15 and divided into a suction side chamber 16 and an insect repellent drug gas supply chamber 17. The blower 13 is disposed across the suction side chamber 16 and the insect repellent chemical gas supply chamber 17. Furthermore, the insecticidal agent gas discharge port 14 is attached along the partition plate 15 and faces the insecticidal agent gas supply chamber 17 side. A mixer 18 is attached to the insect repellent gas supply chamber 17 side between the blower 13 and the insect repellent gas discharge port 14. The mixer 18 is not particularly limited as long as it can be mixed efficiently without impairing the function of the insect repellent chemical gas. In this example, two turbulent flow plates 18a are provided, and when the air flow from the blower 13 is caused to turbulent and the insect repellent gas is released from the discharge port 14, the air flow is efficiently generated. It mixes with insect repellent gas. The installation of the mixer 18 is not an essential condition.

  The air outlet 12 of the airframe 2 forms and blows out an insect-curing agent gas-containing air curtain, and this insect-insulating agent gas-containing air curtain shuts the inlet / outlet 4 in an airflow, so that it is sufficient to shut off the air-inlet. The reach must be given to the air curtain containing insecticide gas. Therefore, by arranging the flow straightening plate 19 in parallel inside the air outlet 12 and providing a run-up space for rectifying the air curtain containing the insect repellent drug gas, it is possible to obtain a reachable distance necessary for blocking. Yes.

  The blower 13 is not particularly limited as long as it has a necessary air volume and wind pressure for obtaining an insect curtain containing an insecticidal chemical gas, but a cross-flow blower is better for dividing a wide space.

  The electrostatic drug spraying device 6 is composed of one or more discharge electrodes 20 and one or more counter electrodes 21 installed in the one or more discharge electrodes 20 with a predetermined space. A discharge part 23 comprising a power source 22 for applying a predetermined voltage, a chemical evaporation part 24 for gasifying an insect repellent, water vapor in the air charged by the discharge part 23 and an insect repellent chemical gas released from the chemical evaporation part 24 Are combined and combined to form a clustered and charged insect repellent drug gas, and a blower mechanism 26 for sending air into the reaction chamber 25, which is clustered from the electrostatic drug spraying device 6. The charged insect repellent gas is supplied to the air curtain device 5 to blow out the air curtain containing the insect repellent gas.

  The discharge part 23 of FIG. 4 shows the simplest configuration for causing discharge. The discharge electrode 20 has a needle shape and the counter electrode 21 has a cylindrical shape. 22 is connected. The shape of the electrodes 20 and 21 of the discharge part 23 is not particularly limited as long as a discharge occurs between the electrodes 20 and 21 and the air can pass therethrough.

  The power source 22 is not particularly limited as long as it can supply the necessary voltage and current to the discharge unit 23. However, a positive charge, a negative charge, or a positive charge is applied to the discharge electrode 20. -There are three cases where negative charges are applied alternately. Depending on the nature of the discharge unit 23, one of the three types of power source 22 is selected, or one that can be switched between three types is selected. The voltage of the power source 22 is not particularly limited, but is in the range of 1 KV to 8 KV. Further, the power source 22 for alternately applying plus and minus charges is not particularly limited, but it is better to use a commercial power source of 50 Hz to 60 Hz.

  The chemical transpiration unit 24 stores and evaporates the insect repellent, and the transpiration means includes a forced heating means and an ultrasonic vibration means. However, natural transpiration is also conceivable. In short, it is only necessary that the amount of insect repellent required can be transpired as needed, and the evaporating means is not particularly limited. In addition, examples of the insect repellent include pyrethroid drugs, but there is no particular limitation.

  The reaction chamber 25 is a chamber in which water vapor in the air charged in the discharge unit 23 and the insect repellent chemical gas discharged from the chemical evaporation unit 24 are mixed and combined. The reaction chamber 25 is formed by the discharge unit 23. It is divided into an upstream reaction chamber 25a and a downstream reaction chamber 25b. The upstream reaction chamber 25a incorporates the air blowing mechanism 26, and the chemical evaporation section 24 is provided in the downstream reaction chamber 25b. Note that the chemical vaporization section 24 itself may be provided outside the downstream reaction chamber 25b, and a nozzle that discharges insecticide chemical gas from the chemical vaporization section 24 may be provided so as to penetrate the wall surface of the downstream reaction chamber 25b. good.

  Accordingly, the air taken from the external space through the inlet 27 and taken into the upstream reaction chamber 25a by the blower mechanism 26 and the water vapor contained therein pass through the cylindrical counter electrode 21 of the discharge portion 23, The water vapor in the air is charged by the discharge unit 23 and further clustered and enters the downstream reaction chamber 25b. The water vapor in the charged and clustered air is mixed and combined with the insect repellent chemical gas from the chemical vaporization section 24 in the downstream reaction chamber 25b to form a cluster, and from an outlet 28 provided in the downstream reaction chamber 25b. The charged and clustered insect repellent gas is discharged into the insect repellent gas supply chamber 17 via the discharge port 14 of the air curtain device 5 and mixed with the air flow from the blower 13 by the mixer 18. Furthermore, a reachable distance necessary for blocking by the rectifying plate 19 is given, and the insect curtain gas-containing air curtain charged and clustered from the outlet 12 is blown out.

  Therefore, for example, if the insect that comes toward the entrance / exit has a polarity opposite to that of the charged insecticide gas, the insect and the insecticide gas 7 are immediately combined, and the insecticide gas acts on the insect. become.

  The air blowing mechanism 26 is not particularly limited as long as it can send air into the reaction chamber 25, but a fan is usually used. In addition, a temperature gradient may be generated to send air into the reaction chamber 25, or an ion wind may be generated to send air into the reaction chamber 25. Further, the air blowing mechanism 26 may be either built in the reaction chamber 25 or installed outside.

Next, a method for preventing insect invasion by the insect invasion preventing apparatus 1 having the above-described configuration will be described.
In the insect intrusion prevention device 1 in a state where the door 3 of the doorway 4 shown in FIG. 1 is closed, first, the insecticidal agent 23 is filled with an insecticidal agent, and then the entire insect intrusion prevention device 1 is activated. Since the air blower 13 of the air curtain device 5 operates, air is sucked from the suction port 11 and blown out from the blowout port 12.

  On the other hand, since the air blowing mechanism 26 of the electrostatic drug spraying device 6 is also operated, air enters from the outside through the inlet 27 into the upstream reaction chamber 25a. Further, air passes between the needle-like discharge electrode 20 of the discharge part 23 and the cylindrical counter electrode 21, passes through the cylindrical counter electrode 21, and enters the downstream reaction chamber 25 b. In the process, when the power source 22 applies a positive charge to the discharge electrode 20, positive ions are released from the discharge electrode 20, and when the power source 22 applies a negative charge to the discharge electrode 20, the discharge electrode When negative ions are released from the discharge electrode 20 and the power source 22 alternately applies positive charges and negative charges to the discharge electrode 20, positive ions and negative ions are alternately discharged from the discharge electrode 20. Therefore, for example, if the power supply 22 applies a negative charge to the discharge electrode 20, negative ions are emitted from the discharge electrode 20 (hereinafter, described as an example where negative ions are emitted from the discharge electrode 20).

  When air containing negative ions from the discharge electrode 20 is charged with water vapor and enters the downstream reaction chamber 25b, insect repellent is evaporated from the chemical vaporization section 24 in the downstream reaction chamber 25b by the evaporation means. The cluster-like insect repellent gas, which is mixed and combined with the drug gas, becomes negatively charged as a cluster, and is negatively charged from the outlet 28 of the downstream reaction chamber 25b, passes through the discharge port 14 of the air curtain device 5 to repel the insect. It is discharged into the drug gas supply chamber 17. It is mixed with the air flow from the blower 13 in the mixer 18 in the insect repellent gas supply chamber 17, and is further given a reach distance necessary to be blocked by the rectifying plate 19, and is charged from the outlet 12. As a clustered insect repellent gas-containing air curtain, the air curtain is blown out to the outer space of the building entrance 4.

  Since most of the insects in the outer space of the entrance / exit 4 are positively charged, the insects near the entrance / exit 4 are combined with the negatively-charged insect repellent gas in the air curtain, thereby preventing the insects. In addition, the entrance / exit 4 and the door 3 and their surrounding walls are usually positively charged, so that the insect repellent is attached and the entrance / exit 4 is invaded by the insect. It becomes a prevention zone and is in a state where insects do not come close. Therefore, after the insect intrusion prevention zone is formed, the door 3 of the doorway 4 is closed, so that the entire insect intrusion prevention device 1 is temporarily stopped.

  When a person is detected by the insect intrusion prevention device 1 or the human sensor 30 attached to the periphery of the insect intrusion prevention device 1, the insect intrusion prevention device 1 is immediately activated before the opening / closing door 3 is opened, and the insect repellent chemical gas is discharged from the air outlet 12. The contained air curtain is blown out, and an insect intrusion prevention zone is newly formed around the entrance / exit 4 to reinforce this. Therefore, even if the open / close door 3 is open (see FIG. 5), insects can be prevented from entering from the doorway 4.

  Here, the case where the door 4 is provided with the opening / closing door 3 has been described. However, when the door 3 is not provided, the door 4 is always open, so that the insect curtain gas-containing air curtain is removed from the insect intrusion prevention device 1. It always blows out and prevents insects from entering the entrance 4. Moreover, although the case where the insect-curing agent gas-containing air curtain is charged has been described, a simple insect-released insect curtain gas has a sufficient effect of preventing insect invasion.

  FIG. 6 shows an insect intrusion prevention apparatus 1A showing another embodiment of the present invention. The difference from the embodiment of FIGS. 1 to 5 is that the electrostatic drug spraying apparatus 6A has an upstream reaction chamber 25a. It is in having a water transpiration unit 31 inside. Therefore, the air that has entered the upstream reaction chamber 25a from the outside through the inlet 27 by the blower mechanism 26 takes in the water vapor from the water transpiration unit 31 in the upstream reaction chamber 25a and opposes the cylinder of the discharge unit 23. It passes through the electrode 21. In the process, the water vapor is mixed and bonded with the ions generated by the discharge unit 23 and charged, and the charged water vapor itself is clustered by hydrogen bonds, and the clustered water vapor is charged to the polarity of the discharge electrode 20. And enters the downstream reaction chamber 25b.

  The charged and clustered water vapor and the insect repellent chemical gas from the chemical evaporation unit 24 in the downstream reaction chamber 25b are combined in the downstream reaction chamber 25b, and the vapor from the charged and clustered water evaporation unit 31 is combined. As a whole, the insecticide gas has a polarity of the discharge electrode 20 of the discharge unit 23 and a large charge capacity, and is discharged from the air curtain device 5 from the outlet 28 provided in the downstream reaction chamber 25b. It is discharged to the insect repellent gas supply chamber 17 via the outlet 14. It is mixed with the air flow from the blower 13 in the mixer 18 in the insect repellent gas supply chamber 17, and is further given a reach distance necessary to be blocked by the rectifying plate 19, and is charged from the outlet 12. As a clustered insect repellent gas-containing air curtain, the air curtain is blown out to the outer space of the building entrance 4. Other configurations and operations are the same as those of the embodiment shown in FIGS. 1 to 5, and therefore, the reference numerals are attached to the drawings and detailed description thereof is omitted. The water vapor transpiration means of the water transpiration unit 31 is the same as that of the chemical transpiration unit 24 of the first embodiment.

  FIG. 7 shows an insect intrusion prevention apparatus 1B according to another embodiment of the present invention. The difference from the embodiment of FIGS. 1 to 5 is that the insect invasion prevention apparatus 1 or 1A and the electrostatic medicine are used. There is no spraying device 6 and a simple air curtain device 5 is combined. Therefore, keep insects away with the insecticide gas in the air curtain containing one insecticide gas, and the air curtain itself prevents its entry, and the insects coming into the entrance / exit with the two air curtains in two steps. Can be prevented. Note that two insect intrusion prevention devices 1 or 1A may be provided to have a two-stage structure. Other configurations and operations are the same as those of the embodiment shown in FIGS. 1 to 5, and therefore, the reference numerals are attached to the drawings and detailed description thereof is omitted.

  As mentioned above, although Embodiment 1 thru | or 3 of this invention was demonstrated, a specific structure is not limited to this, It is applied to the other combination in each claim in the change and addition in the range which does not deviate from the summary of this invention. It should be understood that this is possible as appropriate.

  The insect intrusion prevention method and the apparatus according to the present invention have extremely high applicability when it is desired to prevent insects from entering the building through the entrance regardless of whether the door is open or closed.
