Description

[Detailed description of the invention] insect trap The present invention includes an electric fan and an electric light source disposed on the suction side of the fan. The present invention relates to an insect trap having a cylindrical body.

This type of insect trap captures flying insects and does so without the use of poisons. They are used wherever there is a need to eradicate them.

An example of such an insect-catching playing card is known from U.S. Pat. No. 2,893°161. Ru. In this example, the light source is a circle that fits within the outer rim of the suction end of the tube. It is a cylinder.

However, this known example has certain drawbacks. That is, insects accumulate around the light emitting cylinder. This cylinder also acts as a screen for the airflow generated by the fan. Because of its structure, insects are not sucked into the cylindrical body, and insects are kept in the front part of the cylindrical body. It is by no means efficient as it can easily stay in place.

Furthermore, the mouth on the suction side has an expanded configuration, which increases the airflow velocity. large insects can easily escape from the trap by directly crossing the airflow. It also has the disadvantage of being able to give up.

The purpose of the present invention is to solve the above-mentioned problems of the above-mentioned types of insect traps. and this purpose is to create a light-transmitting sphere with dimensions slightly smaller than the mouth of the tube. around the light source in such a way as to maintain a narrow space for intake air. This can be achieved by establishing the following.

According to this configuration, it is possible to significantly increase the velocity of the airflow along the measuring part of the sphere. Therefore, it is surprisingly easy to significantly improve the performance of insect traps.

With this configuration, insects cannot pass across the airflow; It becomes impossible to escape. Additionally, insects that land on the top of the sphere will land on the sides of the sphere. It tends to crawl out, and this side part gets caught in the airflow and falls inside the cylindrical body. It also turned out that he was going to be sucked in.

In addition to the above, the structure of the insect trap according to the present invention is significantly different from that of known insect traps. It is more hygienic and easier to clean. The reason for this is based on the publicly known example. The light emitting cylinder or bulb becomes so hot that the insects and their excrement dry out. drying and would be very difficult to remove from such light sources, whereas the present invention According to the construction, the sphere can be removed by loosening it from its socket, and its cleaning can be done easily. This is because it is possible to remove Unlike the known example, the surface temperature of the sphere is much lower and therefore its cleaning is significantly easier.

In addition to this, the sphere can withstand loads and external shocks that the light source cannot withstand at all. It also has the advantage that it can be manufactured from materials with high strength such as those available.

By configuring the cylindrical body as described in claim 2 described later, To realize a venturi-like structure which is extremely efficient and economical in operation or operation. I can do that.

Further, as described in claim 3, the top of the sphere is partially protruded. By doing so, the attraction to insects can be significantly increased. This is This is because the soft or gentle light emission attracts insects.

Furthermore, by making the cylindrical body into the shape of a rotating body as described in claim 4, the manufacturing process can be improved. It is easy to construct and also easy to install in a hole in a wall or support.

Finally, the blue-colored spheres according to claim 5 are extremely useful as insect food. It was also found to be effective.

Hereinafter, a more detailed explanation of the present invention will be described with reference to the accompanying drawings, in which: FIG. 1 is a perspective view showing a part of a known structure example with a part removed and a part cut away.

FIG. 2 is a schematic diagram illustrating one example of a built-in insect trap.

FIG. 3 is a cross-sectional view showing an embodiment of the present invention.

FIG. 3 shows a preferred embodiment of the insect trap according to the present invention.

This insect trap has two cylindrical parts, namely a funnel-shaped cylindrical part 13 and a cylindrical part 13. It is constituted by a cylindrical body in which a cylindrical body portion 14 of a shape is combined.

The funnel-shaped cylindrical body portion 13 is cylindrical at its maximum diameter and minimum diameter, It has a truncated conical shape between the maximum diameter part and the minimum diameter part.

The cylindrical body portion 14 can be inserted into the smallest diameter portion of the funnel-shaped tube body portion 13. Then, it is fixed there with, for example, a screw 19.

A light source and a fan are provided within these cylindrical bodies 13 and 14. The light source is It consists of a light bulb 4 fitted in a socket 3 mounted on a cylindrical support member 16.

The cylindrical support member 16 has a large number of spacing members 17, for example four, on one side thereof. These members 17 can be provided in contact with the inner surface of the cylindrical body part 13, It is also provided in contact with the end flange of the cylindrical body part 14, which has a smaller diameter than the cylindrical body part 13. You can leave it.

Furthermore, there is a socket 18 for fitting a blue-colored sphere 15 that covers the light bulb 4. It is attached to the cylindrical support member 16 by means of screws 19.

The dimensions of the sphere 15 are such that its maximum diameter is inside the cylindrical portion at the outer end of the cylindrical body portion 13. It is determined that With this configuration, an annular space 1 is formed, and the size of the annular space 1 is The opening is just enough to allow insects to pass through and the insects occupy this space as effectively as possible. maintain a vacuum or inward air flow 12 strong enough to be drawn through 1; It is something that can be done.

Furthermore, the sphere 15 is configured such that it can emit blue light over an arc of 180°. It has a length such that the rounded top protrudes beyond the cylindrical body part 13 by a certain distance. .

An electric motor 11 is provided at the opposite end or rear end of the cylindrical support member 160. This motor 11 drives the fan or propeller 6 through the shaft, and its rotation Air is sucked in from the space 1 and discharged from the outlet 2.

When the propeller or fan 6 rotates, insects 8 floating in the airflow are crushed. be killed. If there is a risk that this will not kill all the insects, use exit 2. A mesh bag or similar object (not shown) may be provided to trap and collect insects. is possible.

The insect trap of the present invention can operate in all conditions. The known method shown in FIG. As with insect traps, it can be built into the wall, or it can be attached to a supporting member or It is also possible to provide it on a similar object.

Connect the light bulb or electric light 4 and the fan 6 (motor 11) to the power source, and pass the bulb 15 through it. The diffusely emitted blue light can attract insects. insects are spheres As soon as it approaches the body or as it crawls over the sphere into the air stream, it is captured by the inhaling air stream. available. This sends the insects through the cylindrical rod, past the fan section, and into the trap. The insects are killed before they reach the other end or rear end of the trap, but if necessary Depending on the situation, it is also possible to collect insects.
