The base part 50 coupled to the rear surface of the case 10 has a back plate 51 having a discharge port 53 formed thereon so that the sucked air can be discharged, and a side wall 55 formed at an edge of the back plate 51. And an elastic piece 57 formed between the side wall and fixed to the rear plate 51 and the other end of which is elastically movable, and the elastic piece so as to protrude outwardly from the side wall 55. 57 is provided on the outer surface of the engaging jaw 59 is inserted into the fixing hole 17 formed in the side wall of the case.

The back plate 51 has a rectangular plate structure having the same area as the front plate 11 of the case. The outlet 53 is formed in the form of long slits up and down, a plurality of are formed at a predetermined interval. The upper wall of the back plate 51 is formed with a wall hanging hole 52 to hang on the wall.

The side wall 55 of the base portion 50 is formed near the edge of the back plate 51. When the case 10 and the base 50 are coupled, the side wall 55 is formed so that the side wall 55 of the base 50 may be coupled into the side wall 15 of the case. The side wall 55 is formed only on the left and right sides of the back plate 51. This is to allow air to flow through the distribution hole 19 of the case.

The first attracting portion that attracts mosquitoes with light includes a guide plate 20, a support bar 21, a light source 23, and a light guide member 25.

The guide plate 20 is formed in a disc shape and has a diameter larger than that of the suction port to induce a flow of air sucked by the suction fan 60 to the edge. A plurality of support bars 21 are installed to support the guide plate 20 to be spaced forward from the suction port. The front end of the support bar 21 is coupled to the rear of the guide plate 20, the other end is coupled to the edge of the suction port.

A plurality of light emitting diodes are used as the light source 23. The light emitting diodes can effectively attract mosquitoes with colors of various wavelengths. In addition, the small volume and low power consumption are more efficient than conventional lamps. Preferably, a light emitting diode that emits light having a wavelength of 380 to 420 nm is used. More preferably, a light emitting diode that emits light having a wavelength of 400 nm is used. Light at a wavelength of 400 nm can most effectively attract mosquitoes. As the brightness of the light source, 0.6 to 7.1 lux is appropriate, but considering the amount of electricity consumption and indirect lighting, it is preferable that it is 0.6 lux.

The light emitting diodes are arranged on the annular substrate 24 at regular intervals. The substrate 24 is supported by the boss 26 formed on the rear surface of the guide plate 20. In the present invention, the light generated by the light source 23 is not directly irradiated to the suction port, but is indirectly irradiated through the light guide member 20. This is to have a soft lighting effect at night as shown in FIG. The light guide member 25 may be molded by injecting a material such as polycarbonate.

The light guide member 25 is configured in an annular shape and coupled to the rear surface of the guide plate 20 so as to be detachable.

The jaw of the hook 27 is caught by the end of the light guide member 25 to fix the light guide member 25 to the guide plate 20.

A suction fan 60 for sucking mosquitoes attracted around the suction port is installed in the case 10. The suction fan 60 is supported by the fan support means. The fan support means includes a circular mounting portion 65 on which the motor 61 of the suction fan is mounted, and a supporter 67 radially formed on the mounting portion 65 and connected to the support frame 69. The support frame 69 is coupled to the rear surface of the front plate 11 of the case.

When power is applied to the motor 61, the suction fan 60 sucks air through the suction port while the blade 63 coupled to the driving shaft rotates. At this time, the mosquito attracted around the suction port together with the suction of air is also sucked together.

The present invention further includes a second attracting part 70 together with the first attracting part.

The second attracting part 70 is for attracting mosquitoes with incense and is installed in the case or the base part. In the illustrated example, the second attracting portion 70 is installed on the base 50.

The second attracting part 70 includes a cover 71 mounted on one side of the base part 50, and a mosquito attracting agent 75 accommodated in the cover 71.

The cover 71 may be attached to the back plate 51 of the base part using a double-sided adhesive tape, or may be fixed using a separate fixing means. Cover 71 may be formed with a diverging hole on one side so that the fragrance of the mosquito attractant can be diverted to the outside. In addition, the cover 71 may have a structure in which one side is opened and a cap capable of opening and closing is opened at one open side. In addition, the cover 71 may be formed of a porous membrane material that can block the passage of liquid and selectively allow gas to pass therethrough.

The mosquito attractant applied to the present invention gels by adding lactic acid and ethanol to the gelatin solution as shown in FIG. Gelled attractants have the advantage of not flowing down upon receipt in the cover.

Lactic acid is the main component of metabolic products in animals, including humans, to attract mosquitoes. Lactic acid is available in the form of free acid, lactic acid, salts of lactic acid, and combinations thereof. The lactic acid is dissolved in ethanol to uniformly disperse. And mixed with gelatin solution to gel the lactic acid dissolved in ethanol.

The attractant is characterized in that it further contains dipropylene glycol and grapefruit seed extract. Dipropylene Glycol delays the release rate of lactic acid to maintain the long-term effects of mosquito attraction.

And grapefruit seed extract acts as an antioxidant to prevent oxidation. The grapefruit seed extract contains a large amount of sascorbic acid, naringin (Naringin) and tocopherol, it is excellent in antioxidant and antibacterial activity. When a conventional chemical preservative is used, a distinctive odor is generated to avoid mosquito repellent, and there is a concern that the degradation of lactic acid added to the gelatinous solid may be reduced.

Grapefruit seed extract may be commercially available or may be extracted from the grapefruit seeds. For example, after harvesting ripe grapefruit (grapefruit), the pulp is removed and the seeds are separated. The separated grapefruit seeds are washed thoroughly, dried and then ground. 100 g of crushed grapefruit seeds are added to a still, 200 ml of water and 150 ml of glycerin are added to the still, and then the distillator is heated to 80 ° C. to 90 ° C. for 15 to 20 minutes, and then the mixture introduced to the still is filtered. Then poured into a container, the mixture contained in the container can be obtained grapefruit seed extract using a centrifuge.

Examples of mosquito attractants include water 83 to 86% by weight, gelatin 9 to 13% by weight, ethanol 3 to 7% by weight, lactic acid 0.05 to 0.08% by weight, dipropylene glycol 0.08 to 0.20% by weight, grapefruit seed extract 0.07 to 0.20% by weight It is preferable that it is%.

When the content of the gelatin is less than 9% by weight, the water content of the attractant is high and easily dissolved at 28 ° C. or more. And when it exceeds 13 weight%, the directionality will fall and mosquito attracting effect will become low. And lactic acid has a high mosquito capture rate at 0.05 to 0.08% by weight.

The mosquito attractant described above contains lactic acid, which is harmless to the human body and has almost no smell, and has a very high mosquito attracting effect. In addition, since the mosquitoes are attracted together with the first attracting part, the attracting effect can be improved.

The attracting odor of the mosquito attractant is emitted to the surroundings through the discharge hole 53 of the base portion or the distribution hole 19 of the case. In this way, the mosquito attracted by the first and second attracting part is collected by the suction fan 60 together with the air in the collecting part installed in the base part 50.

The collecting part is located behind the suction fan 600. As an example, the collecting part illustrated includes support members 80, assembly panels 90, a receiving panel 100, and a mesh 110.

A total of four supports 80 are formed on the front surface of the back plate 51. The support 80 forms each corner of the rectangular collection part. The support 80 is formed on the back plate 51 beyond the region where the outlet 53 is formed. Each support 80 is formed with two coupling grooves 81 long before and after, as shown in FIG.

Assembly panel 90 is assembled by the end is coupled to the coupling groove of the support (80). The assembly panel 90 is assembled one by one between the supports (80). Therefore, a total of four assembly panels 90 are installed. Each assembly panel 90 is formed with a through hole, the inner side is provided with a net (95). This assembly structure is very easy to attach and detach the assembly panel 90, it is easy to clean the collecting portion.

And the receiving panel 100 is coupled to both ends of the assembly panels 90 disposed on the left and right to form a receiving space 105 for receiving the mosquitoes in the lower portion of the collecting portion. Although not shown, protrusions are formed at left and right ends of the receiving panel 100, and grooves to which protrusions are coupled are formed at the left and right assembly panels 90 corresponding to the protrusions. Therefore, the accommodating panel 100 is detachable to the assembly panel 90. And the receiving panel 100 is installed to form a right angle with the assembly panel disposed below.

The net 100 is installed in the front of the rear plate 51 to cover the outlet 53. Therefore, the air introduced into the collecting portion is discharged to the outside through the discharge port 53, the mosquito is trapped in the collecting portion.
