INSECT TRAP

Abstract

An insect trap comprising a housing comprising an upper chamber and a lower chamber, a cover, a meshy accumulation chamber, and a side wall of the upper chamber is a grate having slot-like openings providing a passage for air and insects, while an axial fan is mounted in the lower chamber, the axial fan configured to transfer the air from the upper chamber to the accumulation chamber. Insect attraction means are two electromagnetic radiation sources, a first being an infrared radiation source arranged on an outer surface of a wall of the lower chamber and formed by a heating element arranged on an inner surface of the wall, and a second arranged in a center of the upper chamber and being a combined infrared and ultraviolet radiation source. A frequency of both radiation sources is within a bioresonance range of infrared waves, while an intensity of the radiation of the second source is greater than an intensity of the radiation of the first source. An escape inhibition means is provided in the trap, shaped as a truncated cone grid directed towards the accumulation chamber, and a height of the grid is less than a height of the accumulation chamber. A heat-insulating element is arranged between the fan and a wall of the lower chamber, and a lower portion of the upper chamber is provided with a conical narrowing towards the lower chamber and has an opening that is connected to an edge of a ventilation channel.

DETAILED DESCRIPTION

[0057] In a preferred embodiment, the insect trap comprises the housing (1) that comprises the upper chamber (2) and the lower chamber (3). The cover (4) is mounted on the upper chamber, the cover may be equipped with the handle (19) to provide convenient trap carrying or hanging, and the meshy chamber (5) is secured to the lower chamber, the meshy chamber is a removable accumulation chamber for caught insects.

[0058] The axial fan (8) is mounted in the lower chamber (3) of the housing (1), and the axial fan is configured to move the air from the upper chamber (4) of the housing to the accumulation chamber (5). The upper chamber (2) is hollow and its side wall is made in a form of the grate (6) having slot-like openings (7) for providing a passage for air and insects. Therewith, the lower portion of the upper chamber (2) is provided with the conical narrowing (11) towards the lower chamber (3) of the housing (1) and has the opening (12) that is connected to the edge of the ventilation channel (9). During operation of the fan (8), the conical narrowing (11) provides the aerodynamic guide that increases the fan's (8) catching zone for the incoming air flow, thereby enabling to catch the insects not only when they reached the inner portion of the upper chamber (2), but also on the approach to its grate.

[0059] In order to attract flying insects, the trap utilizes two main attraction means in a form of electromagnetic radiation sources. The first one is the infrared radiation source that is provided on the outer surface of the wall of the lower chamber (3) of the housing (1) by arranging on the inner surface of the wall of the heating element (13). Therewith, the heat-insulating element (10) is mounted between the fan (8) and the wall of the lower chamber (3), the heat-insulating element is formed as a hollow cup in the exemplary embodiment illustrated in the drawings, in order to stabilize the constant temperature of the chamber (3) surface and to avoid cooling as a result of the fan (8) operation. The second source is arranged in a center of the upper chamber (2) of the housing (1), and it is a combined infrared and ultraviolet radiation source (14). Therewith, the frequency of both radiation sources is within the bioresonance range of infrared waves, while the intensity of the infrared radiation of the second source (14) is greater than the intensity of the radiation of the first source (13). In order to provide such usage conditions, prior art heating and light technologies are used, and these technologies, when combined in the trap structure, allow to create, in the infrared radiation spectrum, an image that is similar to the one that is formed by insect sense organs during perception of a warm-blooded living being. FIG. 5 illustrates a temperature trail for perceiving the mosquitoes by the living being, a large temperature patch of 37? C. in a middle portion of the housing creates a maximum possible zone for detecting and visual contact, when approaching closer to the trap. After the mosquito approached, it seeks for the most vulnerable point to beat and selects the hottest one, i.e., a vein or an artery of the living being. In the present case, this is a gas discharge ultraviolet lamp that is heated up to a temperature of 39-40? C. and arranged in the upper portion of the trap, directly in the suction zone of the fan. The mosquito tends to reach the most vulnerable point, gets into a suction flow and gets into the trap. Owing to the accurate selection of the temperature patch, this embodiment has managed to increase the trap efficiency as high as possible as compared to other similar devices.

[0060] Therewith, the grid (15) is used as the escape inhibition means, and the grid is secured to the lower portion of the housing, a height of the grid is less than a height of the accumulation chamber (5) and the grid is shaped as the truncated cone directed towards the accumulation chamber (5). Therewith, a distance between the gird (15) and a bottom of the accumulation chamber (5) is not more than a width of the openings (7) of the grate (6), thereby making it impractical for the insects to fly out. After the insect got into the upper chamber (2), the fan (8) drags it into the accumulation chamber (5), while the grid (15) inhibits it from escaping from the chamber, and the insects will die in several hours by dehydration. The fan may have two usage modes, i.e., for using outdoors and within a room.

[0061] The trap is equipped with elements for interaction with power supply means, mains and accumulators, its electrical components and the switch-on device (18). The data wireless transmission module (17) may be provided between the cover (4) and the upper portion of the upper chamber (2), i.e., on its end surface (16), for providing a convenient and remote control of the device. The trap may be further equipped with the insect type recognition means (not illustrated in the drawings) arranged in the upper portion of the housing, thereby enabling to receive, process and transmit an information about the operation mode of the device and the type of the insects being attracted.

[0062] The housing may be made of any suitable materials, i.e., metal, plastic, wood, composite materials, etc., while the coloring should be dark, i.e., black, deep green, gray, blue, etc. The lower surface of the housing may be made matte by any known suitable method, i.e., by spraying, structuring, coating, etc. Preferably, the components of the housing are made cylindrical and equipped with a mutual fixation means, thereby providing a convenient servicing and an easy replacement of the components if needed. The trap may have provided in various dimensions that are suitable and sufficient to carry and to hang it. At the same time, many different modifications of both the housing shape and the fixation tools are possible, and they may be easily made by skilled persons without introducing any new matter.

[0063] Therefore, the claimed invention enables to create the insect trap, preferably, for mosquitoes, which provides the effective and reliable possibility of attraction, catching, and retention.
