Control device for flying insects

description

The invention relates to a control device for flying insects, with a sediment evaporation system and a lighting device for attracting the flying insects and with a high voltage grid for destroying the flying insects, which are arranged in a polygonal stand housing with inlet openings for the flying insects, and with a mounted on the housing solar module for off-grid Operation of at least the high-voltage grid and the illumination device.

Flying insects can prove to be true tormentors and are therefore unpopular with humans and animals. Flies, especially mosquitoes, are not only distracting, but also known as transmitters of diseases that can sometimes be fatal. In order to protect themselves from these flying insects, a variety of different fishing methods have been developed.

Known flying insects generally have an enclosure with at least one inlet, at least one attractant for attracting the insects, and at least one means for destroying it within the enclosure. To attract the insects are usually Light sources used, preferably emit UV light, and / or natural or synthetic attractants. In such insect traps may be provided for attracting the insect and heat or noise sources that can be used alone or combined with light and / or chemical attractant sources. As light sources, LED emitters are known in addition to fluorescent tubes and for flowing the attractants fluid evaporation systems. To kill the insects, the known insect traps in addition to high-voltage grids also show adhesive surfaces coated with adhesives and / or pesticides.

A flying insect trap for catching both flies and mosquitoes is disclosed in patent EP 1 213 958 B1. The device described has like conventional fishing gear, an ultraviolet light source with an adhesive strip and in addition an open container, which is provided for receiving a substance that attracts the flying insects to be caught. Flies and mosquitoes are held in place by the tape once they land on it and die. However, the tacky surface of the adhesive strip coated with a sticky substance loses its effect over time, so that the adhesive strip must be replaced at regular short intervals.

For continuous operation more effective than sticky traps are fishing gear, which destroy the attracted insects by pesticides or electric power. There are many types of high voltage traps in which an intense blue light is placed behind a metal grid on which a high voltage is applied. Light-attracted insects fly against the grate, where they are badly burned. Such a device teaches, for example, the utility model DE 20 2006 015 719 Ul

Furthermore, a number of insect traps are known in which the insects are lured onto a pesticide-coated surface in the enclosure.

On a pest that comes into contact with the catch surface, thereby harmful particles are transmitted. The trapped insect takes the rendered Pesticide on and goes under. Such a device is treated for example in the patent DE 693 24 012 T2.

Unfortunately, unlike flies, mosquitoes can hardly be lured by ultraviolet light alone. Also mosquitoes are usually required other attractants than for flies. For example, mosquitoes are particularly attracted to the perspiration of body sweat, blood, lactic acid, sexual attractants and other chemical substances such as carbon dioxide. The presence of CO ₂ indicates concentration of the presence of warm-blooded animals.

Thus, common insect pest traps using natural or synthetic insect attracting agents often employ liquid evaporation systems that promote the flow of attractants. Such evaporation systems are often heated. WO 89/12389 describes an insect eradication arrangement in which the insects are lured into the housing by the release of an attractant stored in the insect trap in a container.

Electric lattice traps, which are preferably equipped for controlling the flying insects with UV light and / or with heated liquid evaporation systems and / or a high-voltage grid, usually require a mains power source for supplying energy. Such known devices for catching and destroying flying insects can only be operated in locations where a power grid is available, for example in or near buildings. Further away, in the open landscape such insect traps can not be used.

There are also known electrical safety devices for flying insects, which are operated independently of the mains. Such devices are powered by batteries or accumulators. For example, reference is made to the publication JP 2005/013 232 A. The document deals with a device for catching and destroying flying insects, which the flying insects with attracts optical and chemical attractants and then fought with a high-voltage grid or with a sticky catch surface. The lures, the high-voltage grid and the sticky catching surface are arranged in an elongate cross-sectional view of rectangular housing, wherein the grid-independent operation of the insect trap, a solar module is provided on a sloping roof surface.

The invention is therefore based on the object to propose in a further development of known insect traps an off-grid control device that can be used individually for different flying insects in all climates of the earth at any point quickly and works over long periods with multiple attractants without regular care trouble-free.

This object is achieved by a control device with the features of claim 1. Further advantageous embodiments can be found in the dependent claims.

Thereafter, in the control device for flying insects according to the invention, the housing has side walls made of metal, in which a box-shaped catching space for receiving the high-voltage grid is formed in an upper region of the housing, wherein the catching space is covered to the outside by a translucent side wall part made of a plastic material on which the inlet openings are arranged. The inlet openings are preferably designed to increase in order to prevent ingress of rainwater into the trap and into the interior of the housing.

The box-shaped catching space, in each of which at least one lighting device is arranged in addition to the high-voltage grid, can be formed as a recess or as an elevation in the side walls of the housing. Ideally, all side walls of the control device are provided with a catching space, so that the flying insects can be attracted from all directions and from all sides via the inlets of the Side wall parts have direct access to the high voltage grids of the control device.

The device for catching and destroying flying insects has in particular a solar module for off-grid operation. As a solar module, all common solar elements can be used to supply individual or all electrically operated devices of the insect control device with the required energy. It goes without saying that the solar energy obtained after the conversion into electricity is buffered by means of suitable electric accumulators in order to operate the proposed device even in the dark. Mosquitoes or flies can only be effectively attracted by the intended light source at or after sunset. In addition, mosquitoes are often nocturnal insects, so that attracting attractants with lures promises only when adjusting or when nightfall particular success.

Thus, the new control device for insects is particularly suitable for use on farms, rice fields in wetlands or resting riverbeds, floodplains, ponds and in case of disaster in flood-prone areas, for home garden and parks, for villas as ornamental pillar element It is also suitable for groves with Bark and book printer beetle infestation. Of course, the proposed device can also be used on the network. Corresponding devices are optionally provided.

The device according to the invention should be effective over long distances. To ensure this, a corresponding size is indispensable. For this purpose, the housing, which is preferably designed tower-shaped in a vertical orientation, have a height of up to two meters or more. This means that the housing can be seen for kilometers from all directions in open terrain and can attract the flying insects to be controlled over long distances with the emitted light and / or the attracted attractants. In the polygonal stand housing, the catching space with the side wall part forms an enclosure for the high-voltage grid. The plastic material of the side wall parts is preferably transparent to the ultraviolet light of the built-in light source. It can be crystal clear or colored, wherein the UV light radiating side wall parts act as a diffuser. Instead of plastic material, plexiglass or quartz glass can also be used in the manufacture of the transparent side walls. In addition to the high-voltage grid, a catching area provided with a sticky or pesticidal substance can be provided in the trap area.

In an advantageous embodiment, the side wall parts are designed as light guides, which light from the illumination device can be fed. As light sources, the illumination device preferably has a number of light-emitting diodes. The light exit surfaces of the light-conducting side wall parts are directed outwards and the associated light entry surfaces are preferably formed on the end sides of the side wall parts, so that the side wall parts radiate the supplied light over a large area into the surroundings of the housing. In the side wall parts, the light of the solar-powered light emitting diodes is coupled. LEDs have a long life and low power consumption with good luminous intensity, which has a particularly advantageous effect on the operating life of the control device in the dark.

The luminous in operation side wall parts of the device have a number of inlet openings for the attracted flying insects. The inlet openings are distributed in a certain grid as evenly as possible over the surfaces of the side wall parts, so that the evaporating in the interior of the catchment area attractants can flow out of the inlet openings over a large area. The flying insects attracted by the light and / or the scented attractants pass through the inlet openings to the destruction devices arranged inside the housing.

Since the device has been specially developed for outdoor use and tropical rain maintenance-free operation, the entire Housing advantageously designed rainproof. This prevents the entry of rainwater from the side and from the top into the housing and thus protects the devices arranged therein from damage. In addition, the atmosphere in the evaporation space, which has a highly concentrated gaseous attractant concentration during operation, is only slightly influenced by the outer air humidity due to the inlet openings of the side wall parts rising towards the catchment space.

The side wall parts of the control device are colored in one embodiment of the invention. Preferably, a light blue transparent material is used for the sidewall parts, so that the sidewall parts made therefrom completely cover the UV light emanating from the illuminator, i. let through without attenuation or forward from the light entry surfaces to the light exit surfaces. Other colored materials are suitable for a corresponding optical appearance of the housing, but with the disadvantage of a lower range of optical attractant.

In one embodiment of the invention, the catching space has a self-luminous rear wall which is arranged on the side of the high-voltage grid opposite the side wall part. The rear wall advantageously carries a coating of organic light-emitting diode material. The coating is preferably a thin pressed and cured film, typically 1-1.5 μm in thickness. Such thin-film luminous components are known as organic light emitting diodes, OLED (organic light emitting diode). OLEDs emit colored light and are much more efficient than other lighting devices due to their low energy consumption. This is particularly advantageous for non-mains powered devices.

The control device according to the invention has for flow of the attractant an entanglement evacuation system for liquids a storage container or a plurality of storage containers, which are arranged in a separate from the catching space of the housing.

The vaporized from the at least one reservoir, the flying insects attracting gaseous attractant is fed to the capture areas of the control device. He exudes over the inlets of the

Housing wall parts to the outside. This is the catching room with the

Entanglement Evaporation each connected via an evaporation channel, which increases towards the trap area. The evaporation channel, which may be vertical or inclined upward, preferably opens down into the trap.

The promotion of the attractant from the reservoir can be supported by a wick system. The wick is arranged in the evaporation channel and conveys the liquid attractant from the at least one storage container. For faster evaporation of the liquid attractant, the attractant evaporation system preferably includes a heater disposed in the evaporation channel. In the event that the entanglement evacuation system operates without wick, the heater may also be located in the reservoir.

For a long trouble-free operation of the control device for flying insects with reduced maintenance, it is advantageous if the destroyed flying insects do not accumulate inside the housing. In order to prevent this, drop channels for the destroyed flying insects are arranged on both sides of the evaporation channel starting from the trap area and preferably lead out of the housing. By dispensing with a collecting container within the housing a secure operation of the control device is ensured over a long period.

It is known that different flying insects are attracted by different attractants. Therefore, preferably several evaporation systems with independent storage containers with various attractants integrated into the device, so that several fragrant attractants can simultaneously serve as a lure. It has proven to be useful to use for each of the fishing areas at least one associated liquid evaporation system with its own associated reservoir. However, it is also possible to carry out the evaporation channels such that each of the fishing areas is supplied with different attractants.

In a variant of the invention arranged for easy filling of the reservoir outside of the housing arranged filler neck, leading to the reservoirs. In a particularly expedient embodiment of the control device according to the invention, the at least one storage container is arranged in the housing behind the catching space and the at least one accumulator for the solar module below the storage container. In the case of several storage containers, these are ideally stacked one above the other. It has proven to be useful to provide the reservoir and or the battery outside with an insulating jacket to counteract unwanted heating by sunlight.

Advantageously, in one embodiment of the invention, the side wall parts of the control device are releasably connected to the respective side wall. The side wall parts are preferably held by vertically extending guide rails. This has the advantage that the side wall parts for replacement in the event of damage and for an occasional inspection of the catching space can be easily and quickly removed from the housing walls and can be re-attached without tools.

In various preferred embodiments of the device, the housing has a base from which vertical standpipes extend in the manner of a frame up to a cover of the housing which carries the solar module. With a suitable size, the solar module alone can form the lid. At the stanchions, the metallic side walls of the housing are detachable or permanently attached. For any maintenance, it may be useful to detachably attach at least one housing wall to two uprights.

In order to distribute the light and the at least one attractant to attract the insect as evenly as possible in all directions, the housing is advantageously arranged rotatably on a pedestal. In this case, the housing can move continuously in one direction or alternately in the opposite direction. The drive of the housing is ideally carried out via an electric drive motor, which is powered by the provided solar module with power.

The invention will be explained in more detail with reference to an embodiment. Further features of the invention will become apparent from the accompanying drawings and the description of the embodiment in conjunction with the claims. The individual features of the invention may be implemented on their own or in several different embodiments of the invention. In a schematic representation show:

Figure 5 is a longitudinal sectional view of the device according to

FIG. 1 FIG. 1 shows a control device 1 according to the invention for catching and destroying flying insects. The device 1 is designed with a vertically elongated, in cross-section triangular stand housing 2, which extends from a square base 3 away. The housing 2 has an upper region 4 and a lower region 5. In addition, the housing 2, as shown more clearly in FIGS. 2, 3, has three metallic side walls 6 with translucent side wall parts 7. The side wall parts 7 are arranged in the upper region 4 of the housing 2 on the side walls 6 and releasably connected to the side walls 6.

As can be seen from FIG. 2, the side walls 6 of the housing 2 are fastened to vertically extending stanchions 8 in the position of use of the control device 1. The standpipes 8 extend between a bottom 9 and a cover 10 of the housing 2, wherein the bottom 9 is rotatably connected to the base 3. On the upper cover 10 of the housing 2, a preferably cube-shaped solar module 27 is mounted outside, which is shown in the drawing in Figures 4, 5 suggestively. The solar module 27 supplies the electrical operated devices of the device 1 with solar power. The bottom 9, the lid 10 and the three in the same dimensions side walls 6 form a symmetrical columnar housing 2. At least one of the three side walls 6 is detachable from the uprights 8 and thus removable from the housing 2 for inspection and / or maintenance.

The side walls 6 are formed opaque except for the side wall portions 7, while the side wall portions 7 are formed of a light-conducting and partially translucent plastic material and have inlet openings 11 to a trap space 12 of the control device 1. In the catching space 12, a high-voltage grid 13 for the destruction of attracted flying insects at a distance from the side wall portion 7 is arranged. The housing 2 has on each side wall 6 behind the side wall portion 7 such a trap space 12 which is substantially closed to the interior of the housing 2 out. Figures 2, 3 also show that the side wall portions 7 are held by parallel to the uprights 8, a lateral distance to these having guide rails 14. The side wall parts 7 are detachably connected to the respective associated side wall 6 by way of two respective guide rails 14 made of a suitable plastic material. The side wall parts 7 can be easily inserted into the guide rails 14 with the cover 10 removed from above. An additional attachment is not necessary.

To illuminate the catching space 12 and attract the flying insects by means of light, the control device 1 has a visible only in the figure 5 lighting device 15, which is formed by a number of light-emitting diodes. The light-emitting diodes 15 are arranged distributed along the guide rails 14 of the side wall parts 7 which act as light guides, with the guide rails 14 coupling the light emanating from the LEDs 15 laterally into the side wall parts 7. The solar module 27, which is not shown in FIGS. 1, 2, 3, is connected to accumulators 16 arranged in the lower region 5 of the housing 2 for storing the solar power, which in turn supply the illumination device 15 and the high-voltage grid 13 with stored current. The accumulators 16 according to FIG. 2 are thermally insulated from the environment by a surrounding insulating jacket 17. As an optical attractant, the catching space 12 has a self-luminous rear wall 28, which is arranged on the side of the high-voltage grid 13 opposite the side wall part 7. The rear wall 28 shown in FIGS. 2, 3, 5 carries a film with organic light emitting diodes (OLEDs) as a coating.

To attract the flying insects, the control device 1 has three entrainment evaporation systems 18 shown in FIG. 5, with which natural and synthetic attractants can flow. According to FIG. 4, each of the catching spaces 12 is assigned its own attractant evaporation system 18, which in each case has an evaporation channel 19 which leads to the corresponding catching space 12. The evaporation channel 19 opens below centrally in the trap 12. Right and left of the evaporation channel 19 are, as the figure 4 shows, vertically extending funnel-shaped drop channels 20 which lead out of the catching space 12 and out of the housing 2. Through the drop channels 20, the destroyed flying insects fall out of the catching space 12 and the housing 2 without further measures.

FIG. 4 shows one of the side walls 6 in plan view from the outside. In the upper region 4 of the housing 2, the side wall part 7 is arranged on the side wall 6 as a transparent luminous skeleton 22 made of a light blue plastic material. The skeleton 22 determines the number of inlet openings 11 of the side wall parts 7, which are distributed uniformly over the side wall part 7. As can be seen in FIG. 5, the entry opening 11 is adjoined in each case by an entry channel 21, which ascends obliquely upwards, to the catching space 12, which prevents rainwater from passing through the entry opening 10 into the catching space 12 of the housing 2. The inwardly upwardly directed inlet channel 21 makes the inlet openings 11 rainproof. The lid 10 carries the solar module 27, the power supply lines to the accumulators 16, the lighting device 15 and the high voltage grid 13 are not shown.

The flying insects are optically attracted by the in operation of the control device 1 shining blue skeleton 22 of the side wall parts 7, wherein the

Gerippe 22 light is supplied from the illumination device 15. Next to the

Side wall part 7 are on one of the side walls 6, as shown in Figure 4, three leading to the reservoirs filler neck 23 for the liquid

Attractant arranged. With the help of the filler neck 23, the long-term reservoir 24 symbolically shown in Figures 3, 5 of the attractant evaporation systems 18 can be filled with the attractants, without the

To open housing. The respective attractant evaporation system 18 is arranged directly below the catching space 12 and has one more

Short-term storage container 25 in which a wick 26 dips, which extends to the evaporation channel 19. FIG. 5 shows the control device 1 for flying insects with the cube-shaped solar module 27 in a longitudinal section. More clearly than in the other figures, the spatial arrangement of the reservoir 24, 25 and the illumination device 15 can be seen. It can also be seen that the attractant evaporation systems 18 are arranged with the reservoirs 25 and the wicks 26 below the catching spaces 12 and the reservoir 24 behind the catching spaces 12. The connecting lines between the reservoirs 24 for the long-term storage of liquid attractants to the reservoirs 25 with the wick 26 are not shown.
