Description

[Detailed description of the invention] Purpose of the invention (a) Industrial application field The present invention relates to an insect trap that uses suction power to suck in insects that gather around a lighting device.

(b) Conventional technology For example, insecticides that use electric shock are distributed in the market, but they produce shocking sounds or unpleasant odors due to electrocution, and their efficiency decreases when used at the same time as other lighting devices. However, there is a reputation that it loses its function when insects appear.

(c) Problems to be solved by the invention By replacing the conventional electric insecticidal means with a technical means that uses suction wind power,
Technical issues such as the aforementioned reputation can be solved.

(d) Means for Solving the Problems The technical means of the present invention will be explained with reference to FIG. 1. In the upper half, there is a duct hose insertion port 15 whose lower part is tapered and whose top end is connected to a suction device.
A cylindrical suction hood A1 is provided in the lower half, and a cylindrical suction hood B9 is provided in the lower half to shield about the upper 1/3 of the light bulb cover 7 that hangs down from the center, and the upper and lower halves are combined. to create a cover necessary for suction,
Through this, an effective suction wind force is applied around the illuminator. In addition, the distance between the inwardly curved circumferential portion of the lower end of the suction hood B9 and the surface of the cylindrical light bulb cover 7 is made as narrow as possible to a gap of 2 cm or less. To obtain a strong suction air layer on the surface of a light bulb cover 7.

(E) Function Inside the suction hood A1, the suction air sent from the suction hood B9 joins at the tapered part, and has the function of increasing the speed in the direction of arrow D and sending it later. The inwardly curved lower end prevents insects from escaping and improves insect trapping efficiency.

(f) Effects of the invention According to this invention, in addition to being able to solve the technical problems of the conventional technology, it also exhibits the characteristic of sucking in the insects that gather without interruption even during extremely quiet suction. The average number of insects that cannot be sucked in after stopping suction is approximately 0.1 of the total amount of insects caught.
Judging from the fact that it was about %, it was certainly recognized that there was a technical effect.

(G) Example As shown in FIGS. 1 and 2, the device retaining plate 4 is made of a metal plate folded in half at right angles, with screw holes 13 drilled in the vertical plate and circular cut-out windows 14 provided in the horizontal plate. On top of the circular cutout window 14, place the suction hood A1 whose lower end is bent outward in a brim shape and the lower half is tapered, and on the back side, the upper end is bent outward into a brim shape and the lower end is inward. Tighten the bent suction hood B9 with the set screw 12. Next, the lighting fixture mounting plate 2 is provided by being fixed to the four mounting supports 3 which are welded to the inside of the lower end of the suction hood A1 and projected inward. To this board,
Insert the light bulb socket 6 with the light bulb 8 attached inside the light bulb cover socket 5, attach the light bulb cover 7, and tighten with the screws 10. In this case, the hose is connected to the duct hose insertion port 15 at the top of the suction hood A1, and based on practical experience, an air volume of about 6 to 7 m ³ /min seems best.

Claims (1)

[Scope of utility model registration request] A screw hole 13 is made in one vertical plate of the device retaining plate 4 which is folded in half at a right angle, and the lower half is tapered and the lower end is bent outward into a brim shape above the circular cutout window 14 in the other horizontal plate. Place the hood A1 on top of the cylindrical suction hood B9, which bends the upper end outward like a brim and bends the lower end inward to shield the upper part of the light bulb cover 7, and tighten them with the screws 12 to remove the suction air. Insert the light bulb socket 6 into the light bulb cover socket 5 on the lighting equipment mounting plate 2 held by the tip of the mounting plate support 3 which is fixed to the inside of the lower end of the suction hood A1 and protrudes inward to form a ventilation path, and tighten with the screws 10. A suction type insect trap for a lighting device, characterized in that it has a lighting device attached thereto and is configured to suck air around the lighting device.
