Description

Mosquito lamp structure

The invention relates to a mosquito trap lamp; in particular to a mosquito trap lamp structure which is environmentally friendly, safe, non-toxic, noise-free and has high efficiency and anti-mosquito effect.

Mosquitoes not only suck blood, but also infect diseases. After mosquito bites, the affected area often becomes red and swollen and itchy, and allergic people will take a long time to heal. Therefore, people are eager to reduce the number of mosquitoes, so there are mosquito coils, mosquito traps, etc. The device came out.

The methods used today to combat mosquitoes are as follows:

1. Mosquito coils, insecticides, electric mosquito-repellent incense tablets and electric mosquito-repellent incense liquids, all of which are based on pyrethroids, but these products are resistant to cancer and cause cancer in long-term use.

Second, anti-mosquito liquid: the use of ethyl for the ingredients, but the use of skin redness, allergies, smearing on young children may cause the risk of eating and other issues.

3. Electric shock type mosquito trap light: It is based on the light-repellent nature of mosquitoes at night, using light trapping and then killing it by the power grid. However, when the power grid touches the mosquitoes, it will produce a considerable sound, in addition to noise, it will be more Sudden sounds cause shocks to others, and the power grid is exposed to the danger of being touched. In addition, when mosquitoes are subjected to electric shock, they will explode mosquito body debris, hair and residual limbs, and easily spread bacteria and viruses through the air. Caused secondary pollution, such as causing asthma, rhinitis; in addition, cleaning the grid is also quite troublesome, it will feel quite dirty after a long time, which is its shortcoming.

In addition, in order to capture small mosquitoes such as black mosquitoes, the grid must be made into fine mesh, but when a large mosquito is captured, the body will always short-circuit the mesh of the grid and continue to shock until Until it is burnt, it is easy to produce a fire or even a fire, which is a disadvantage.

In view of this, the main object of the present invention is to improve the aforementioned disadvantages, thereby providing a mosquito lamp structure which is environmentally friendly, safe, non-toxic, noise-free, and has high efficiency of mosquito killing.

According to the above object, the mosquito lamp structure of the present invention mainly comprises a base, a mosquito trap box disposed on the base and an exhaust fan disposed on the top surface of the mosquito trap box, and the base is provided with a conversion The drive circuit of the power supply required for each functional structure; the mosquito trap case further comprises: an inner layer shell, wherein the front and rear side surfaces are respectively extended from the peripheral edge to the radial direction to form an extension portion, and the extension portion is provided with a In the above-mentioned long through hole, a plurality of gates and a vent opening at the top end of the inner casing are opened on the peripheral surface of the inner casing, and the first filter screen is disposed in the vent, and the gate is provided with a pivot The shutter of the gate can be closed; the exhaust fan is positioned on the first screen of the vent, and the front side surface of the inner casing is provided with an opening opening communicating with the interior; the upper edge of the opening is The cover plate is provided with a cover for opening and closing the opening; the light-emitting member is disposed on the peripheral surface of the inner casing; the outer cover is disposed outside the inner casing to cover the peripheral surface of the inner casing and the light-emitting The upper end of the outer cover is openable Vent port communicating with the exhaust ports is provided with a grid, outside surface of the outer edge of the exhaust port on both sides of the cover, defines more than a system of elongated through-hole.

In implementation, the light of the light-emitting member is used to induce the mosquito to enter between the inner shell and the outer shell through the long through hole of the inner shell or the outer shell, so that the suction flow generated by the exhaust fan can be suctioned. Insect mosquitoes are sucked into the inside of the mosquito trap and air-dried to death; when the power is turned off, the suction disappears, and the brakes will close the gate again due to their own weight, preventing the surviving mosquitoes from escaping; when cleaning, just cover the cover The inside of the mosquito trap can be cleaned. Accordingly, the present invention can achieve the effects of safety, environmental protection, non-toxicity, no noise, and high efficiency in killing mosquitoes and rapid cleaning.

The suction of the air fan (6) disappears, and the brake pad (34) closes the gate (32) again due to its own weight, which prevents the surviving mosquitoes from escaping; in addition, when cleaning, the cover only needs to be turned over. Clean the inside of the mosquito storage room (20). Accordingly, the present invention has the advantages of safety, environmental protection, non-toxicity, no noise, and the like, and can achieve high efficiency in killing mosquitoes and quick cleaning.

Furthermore, in order to capture a small mosquito such as a black mosquito, a pressing piece (44) may be disposed above the grid (400) of the outer cover (4), the pressing piece (44) The bead is formed in a square shape, and a second filter (440) having a mesh smaller than the first filter (310) is disposed between the bead. After being installed, the black mosquito can be effectively prevented from escaping through the exhaust port (40) of the outer cover body (4) via the first filter screen (310), thereby achieving the effect of fully capturing mosquitoes.
