Description

[Detailed description of the invention] Technical field of the invention This invention uses the phototaxis of mosquitoes and the property that their blood-sucking behavior becomes active in response to a moderate amount of human exhalation (carbon dioxide gas) to actively kill mosquitoes. This invention relates to a mosquito trap for attracting and capturing mosquitoes.

Conventional technology As a device for attracting and capturing wind-flying pests, light wavelength
A device that attracts pests with a 350 to 500 nm attracting light and captures them using the wind force of an air blower and a suction fan has been used for a long time. However, the device
Although it has a uniform effect on all phototactic flying pests, it is not necessarily effective against mosquitoes that have unique behavioral characteristics other than phototaxis, such as Culex mosquitoes.

Purpose of the invention Therefore, the purpose of the present invention is to target mosquitoes among flying pests, and to attract mosquitoes by utilizing their phototaxis and the property that blood-sucking action is activated in response to exhalation. The method is to strongly attract them near lights and capture them with insect filters.

Summary of the invention Therefore, the present invention provides a carbon dioxide gas supply means and a ventilation fan within the upper cover facing toward the insect trapping box, a suction fan at the lower end of the insect trapping box, and further connects the upper cover with the insect trapping box. An attraction light and a reflector are installed at the connection point.

When catching insects, the carbon dioxide gas passes through the space of the attraction light and flows into the insect trap box as air with components similar to exhaled air. At this time, mosquitoes are strongly attracted to the space near the attracting light due to their ability to approach exhaled air and their phototaxis. During this time, the air flow from the blower fan passes through the attraction light and is sucked into the insect filter in the insect trap box, so nearby mosquitoes are captured inside the insect filter along with the air flow.

Configuration of Embodiment Hereinafter, the configuration of an embodiment of the present invention will be specifically described based on the drawings.

1 and 2 show the structure of a mosquito trap 1 of the present invention.

The mosquito trap 1 is composed of a stand 2, an insect trap box 3, an upper cover 4, and an attraction light 5 as main parts.

The stand 2 is a funnel-shaped hollow pole 2a.
A base 2b is formed at the lower end of the pole 2a.
A cylindrical insect trap box 3 is attached to the upper end of the container.

A check valve 6, an insect filter 7, and a suction fan 8 are housed in this insect trapping box 3 in this order from the top to the bottom. Here, the insect filter 7 is shaped like a container, and its opening is attached to the attachment member 9 with a stopper 10. A single-open door 11 is provided on the side of the insect trapping box 3, and when the door 11 is opened, an operator can attach and detach the insect filter 7 from the outside for replacement.

Further, the suction fan 8 is attached to the bottom of the insect trap box 3, and its suction port 12 is directed toward the center inside the insect trap box 3, and the protrusion port 13 is directed toward the center of the inside of the insect trap box 3.
is directed downward into the pole 2a and also toward the passage port 25. Furthermore, the check valve 6 is
For example, the mounting member 9 is made of a rubber sheet.
It is attached to the insect trapping filter 7 so as to close the opening thereof, and when the suction fan 8 is suctioning, it is elastically deformed and opened by the suction force.

On the other hand, an upper cover 4 is attached to the upper end of the insect trapping box 3 via a plurality of hollow connecting poles 14 erected along the outer peripheral edge thereof. Inside this upper cover 4, a heater 15, a carbon dioxide gas cylinder 16 as a carbon dioxide gas supply means, and a flow rate control valve 17 are attached on the upper side. Further, at the lower end, a humidifier 18, a timer 19 as a control means, and a blower fan 2 are provided.
The suction port 26 of this fan 20 is directed into the upper cover 4, and the discharge port 27 is directed toward the insect trap box 3.

Further, downward from the lower end of the upper cover 4, for example, two guide lights 5 and a green net-shaped reflector plate 22 to which a heater 21 is attached are attached. That is, these are housed in a space surrounded by the connection pole 14.

Effect of the embodiment Next, the operation of the mosquito trap 1 of the present invention will be explained.

This mosquito repellent 1 is installed outdoors or indoors,
When the attraction light 5 lights up and the light gathers on the reflector plate 22,
Mosquitoes are attracted to the reflected light. At the same time, an appropriate amount of carbon dioxide gas 23 is supplied from the carbon dioxide gas cylinder 16 into the upper cover 4 by the flow control valve 17 . This carbon dioxide gas 23 is heated and humidified by a heater 15 and a humidifier 18, and mixed with air to become an air flow 24 similar to human exhalation.
0 sends it downward. The air flow 24 sent downward passes through the attraction light 5 and the reflection plate 22, opens the check valve 6, is sucked by the suction fan 8, passes through the insect filter 7, and enters the pole 2a. Flow into.

That is, by generating an air flow 24 similar to exhaled air in the space near the attracting light 5, the phototaxis, which is a characteristic of mosquitoes, and the activation of blood-sucking behavior in response to exhaled breath (carbon dioxide gas) are promoted, thereby actively attracting mosquitoes. do.
Further, since the reflective plate 22 is heated to an appropriate temperature by the heater 21, mosquitoes are attracted by the temperature and try to stop on the surface of the reflective plate 22. The mosquitoes attracted near the attracting light 5 in this way are moved to the insect trap box 3 by the air flow 24.
The insects are sucked into the insect trap and captured by the insect filter 7.

Note that a part of the air flow 25 sucked into the pole 2a through the suction fan 8 becomes a circulating flow due to interaction with the blower fan 20 through the passage hole 25 formed on the outer circumferential side of the lower end of the insect trapping box 3. through,
Some carbon dioxide gas 2 rises up the inner peripheral surface of the insect trap box 3, passes through the connection pole 4, and enters the upper cover 4.
It is circulated with 3.

In addition, a flow rate control valve 17, a humidifier 18, a heater 2
1. A series of operations of the blower fan 20, attraction light 5, and suction fan 8 are timely controlled by a timer 19 as a control means. On the other hand, the captured mosquitoes are collected by each insect filter 7 through the opening/closing door 11 and disposed of. Of course, the check valve 6 closes the upper surface of the insect filter 7 when it is not in operation.

Effects of the invention The mosquito repellent of this invention combines the attraction with an attraction light that uses phototaxis and the attraction that uses a reaction to airflow similar to exhalation, so it actively attracts mosquitoes near the attraction light. In addition to being able to attract mosquitoes, this airflow reliably sends the attracted mosquitoes to the capture filter and captures them in a state where they cannot escape, increasing capture efficiency.
