Description

[0001] INSECTICIDE OR REPELLENT DEVICE, INDOORS OR OUTDOORS

[0002] The present patent relates to insect repellent devices and in particular it concerns a novel insecticidal or repellent device.

[0003] There are many known types of repellent or insecticidal devices having the purpose of repelling or killing pesky or annoying insects of various kinds, such as mosquitoes, flies, stink bugs, etc.

[0004] There are known devices that use laser technology to strike such insects, either killing them or making them unable to fly.

[0005] For example, patent document KR2021121658A discloses a laser barrier applicable to a window opening and comprising two reflective surfaces on the two jambs of the opening and three laser emitters positioned in an upper corner of the opening, between a jamb and the lintel. The three emitters emit laser beams parallel to each other and oriented slightly inclined downwards and towards the opposite jamb so that the beam is reflected several times by the reflective surfaces, thereby creating a sort of barrier that occupies the whole opening. The three beams are oriented so as to identify three parallel planes, and in particular a first detection plane on the side of the opening facing towards the outside, which has the function of detecting the possible entry of an insect, and a second detection plane on the side of the opening facing towards the inside, which has the function of detecting the passage of a human being.

[0006] Between the two detection planes, the third emitter generates an insecticidal plane that is activated when the entry of an insect is detected and deactivated when the passage of a human being is detected.The laser emitters shown in this document are not orientable but are exactly oriented to ensure that the laser beams are correctly reflected so as to form the insecticidal barrier in the opening.

[0007] The device is in fact dimensioned and structured according to the size and shape of the opening and, moreover, it cannot be moved, for example, from one opening to another, if necessary, being built into the frame of the opening. Furthermore, the system is not designed to be applied, for example, outdoors. Patent US11825580B2 also discloses a repellent barrier against insects which comprises two detection light emitters mounted inside a U-shaped profile mounted on a jamb of the opening. Other U-shaped profiles, inside which sensors are present, are mounted on the other jamb and on the lintel.

[0008] When an object passes through the opening, the sensors detect the size of the object and, if they verify that it is an object having the size of an insect, the system will activate a laser emitter with targeting, which will strike the insect to kill it. In this case as well, the system is highly complex and needs to be sized and structured based on the size and shape of the opening.

[0009] Patent KR1473637B1 shows a device with numerous laser emitters arranged along the perimeter of the opening which emit beams in a vertical, horizontal and oblique direction and create a repellent laser barrier.

[0010] There are also known devices with a targeting system, wherein the laser emitters are oriented based on the position of the insect to be struck, which is detected, for example, by monitoring ambient sounds, following the buzzing of the insects, or by means of cameras. However, this type of devices is not plausibly applicable in contexts, for example, outdoors and frequented by people, where the number of mosquitoes or other insects is very high andthere exists a risk of being struck by the laser beam. In order to obviate all the aforesaid drawbacks, a novel type of repellent or insecticidal device was designed and produced.

[0011] Patent BR9306537A discloses a method and associated apparatus for laser pest control. In particular, this patent describes the use of a laser beam that is scanned over a defined area and renders the sensory organs of the pests incapacitated when they enter into said area. This control system uses a laser source in cooperation with a reflective scanner that then repeatedly directs the laser beam throughout the defined area. A pest that ventures into this area, or is attracted to it, for example by bait, is intercepted by the laser beam. The latter has sufficient energy to destroy the sensory organs and render the pest incapacitated.

[0012] More specifically, patent BR9306537A envisages repeated scanning of a predefined area using a laser scanning system. A laser source produces a laser beam, a scanner directs the beam according to a predetermined, repetitive pattern, and an attractant (or bait) is disposed in said predefined area. The scanner comprises a pair of reflectors (i.e. mirrors) rotatable on axes orthogonal to each other. Drive units associated with each reflector rotate the reflectors themselves. Operationally, the beam is reflected in succession by means of the reflectors so that the rotation of the reflectors causes the beam to move in the X and Y directions. The main task of the present invention is to create a continuous barrier, impenetrable to insects, in a closed environment or outdoors.

[0013] Another object is to be able to position the device in any door or window opening, of any shape and size, without requiring any structural modificationto the device itself or to the structure of the opening.

[0014] Another object is to create a flat barrier, applicable for example to protect an opening, or a three-dimensional one, thus also applicable outdoors to create a three-dimensional volume protected by a complete barrier. These and other objects, direct and complementary, are achieved by the novel repellent or insecticidal device, comprising in the main parts thereof:

[0015] a containment body with constraining means for fastening said containment body to a support, which can be a side of a door or window opening or of a passage in general or can be any support; At least one laser emitter, housed in said containment body and adapted to emit at least one laser beam in a first direction and at a given frequency, which is harmful or repellent for at least one type of insect;

[0016] At least one reflective body housed in said containment body and having at least one reflective surface facing towards said emitter so that said at least one laser beam is incident on said surface with a given angle and is reflected in a second direction;

[0017] - Means for rotating said reflective body about a rotation axis parallel to and coincident with said incident beam, forming an angle P with said reflective surface, and wherein the rotation of said reflective body continuously brings about a change of said second direction of reflection of the beam which, by rotating, will define a flat or conical surface as a function of said angle P,

[0018] and wherein said containment body comprises at least one window or aperture adapted to enable the exit of said reflected beam.More particularly, if said angle P is 45°, the surface defined by the reflected beam will be substantially flat, whereas if said angle P is greater than 45°, said surface defined by the reflected beam will be a conical surface enclosing the incident beam.

[0019] The novel device may be placed, for example, on the lintel of a door or window opening and disposed so that the reflected beam defines a flat surface parallel to the plane of the door or window opening, thereby creating a barrier that prevents the passage of insects.

[0020] The novel device may also be placed suspended at a certain height above ground, for example outdoors, and disposed so that the reflected beam defines a downwards conical surface, thereby creating a sort of volume laterally enclosed by the conical surface and at the bottom by the ground, into which the introduction of insects is precluded.

[0021] It is envisaged that said laser emitter may be configured to emit two or more laser beams at a different frequency, and more particularly at frequencies that are harmful or repellent for two or more different types of insects.

[0022] It is further envisaged that said laser emitter may be configured to emit a laser beam having within it a plurality of frequencies, i.e. a multifrequency beam. It has in fact been found that different laser frequencies have different effects on various insect species.

[0023] For example, it is possible to provide for beams with frequencies capable of killing the insect or making it unable to fly. It is also possible to provide for beams with frequencies that are repellent for insects, which in this case will not be killed or injured but will be simply kept away.

[0024] The device conveniently also comprises means for supplying power to saidlaser emitter and said rotation means, which can provide for a connection to an external electrical grid, or a connection to a battery or to devices for the generation of electricity from renewable sources.

[0025] It is further conveniently envisaged that said window or aperture may be covered with glass or a surface transparent to laser beams, which will act as protection for the emitter, the reflective body and the other components contained in the containment body, preventing the introduction of dirt or tampering with the components.

[0026] It can also be envisaged that the novel device is installable in combination with other structures which, as will be better described below with the aid of the drawings, may comprise reflective profiles that deflect the reflected beams to create protective surfaces with a shape differing from a simple flat or conical shape.

[0027] The features of the novel insecticidal or insect repellent device will be better clarified by the following description with reference to the drawings, appended by way of non-limiting example.

[0036] - Figure 6a shows a schematic representation of the operation of the device in figure 6;

[0037] - Figures 7 to 22 show particular applications of the device in figures 1 and 4.

[0038] In accordance with the embodiment of the invention illustrated in figure 1, the device 100 comprises a containment body 200, for example substantially box-like, present inside which there is a laser emitter 300 which emits at least one laser beam in a first direction X.

[0039] In the example shown in figure 1, the laser emitter 300 emits three different laser beams A, B, C, for example of different frequencies to strike insects of a different type.

[0040] The beams emitted A, B, C are all preferably parallel to a first direction X. Present inside the containment body 200 there is a reflective body 400, having at least one reflective surface 410 facing towards said emitter 300 so that said one or more emitted beams A, B, C are incident on said reflective surface 410 with a given angle a other than 90° and reflected in a second direction Xr, thereby generating a reflected beam Ar, Br, Cr, as schematically illustrated infigure 1.

[0041] Said reflective body 400 rotates about a rotation axis Y coincident with or parallel to said first direction X of emission of said one or more beams A, B, C.

[0042] For this purpose, the reflective body 400 is connected to a rotation pin 420 (or a shaft), mounted on the opposite side with respect to said reflective surface 410 and connected to a rotation motor 430, which is likewise contained in said containment body 200.

[0043] Said rotation axis Y is oriented so as to form with said reflective surface 410 an angle P other than 90° and greater than 0°, shown in figure la.

[0044] The rotation of said reflective body 400 continuously brings about a change of said second direction Xr of reflection of the reflected beam Ar, Br, Cr, which, by rotating, will define a flat or conical surface as a function of said angle p.

[0045] More particularly, if said angle P is 45° as in the diagram in figure la, the beam A, B, C will be reflected so that the second direction Xr is substantially orthogonal to the rotation axis Y and the surface defined by the reflected beam Ar, Br, Cr will be substantially flat and orthogonal to the rotation axis Y. If, by contrast, said angle P is greater than 45°, as in the diagram in figure 4a, said surface defined by the reflected beam Ar will be a conical surface enclosing the incident beam A. As the angle P decreases, the width of the conical surface will increase progressively until becoming a flat surface with P=45°.

[0046] With an angle P of less than 45°, the conical surface will be facing the opposite side of the incident beam.According to one aspect of the invention, the reflective body 400, and in particular the reflective surface 410 thereof, may be inclined relative to the rotation axis Y to adjust the angle P so that it can take on a plurality of predefined values.

[0047] In other words, the reflective body 400 and, consequently, the reflective surface 410 thereof, can rotate about a rotation axis orthogonal to a plane on which the rotation axis Y and the first direction X lie (see figures 4 and 4a). In this manner, the angle P formed between the reflective surface 410 and the rotation axis Y, can take on a plurality of values, and the laser beam incident on the reflective surface 410 of the reflective body 400 will be reflected in accordance with said angle p.

[0048] Advantageously, this changing of the angle P makes it possible to generate a plurality of laser barriers having a variable desired width, for example a pre-established conicity.

[0049] According to one aspect of the invention, the insecticidal or repellent device 100 comprises a single reflective body 400.

[0050] Advantageously, the single reflective body 400 is housed in the containment body 200, thus making the device 100 compact and not cumbersome.

[0051] In addition, the single reflective body 400 enables the laser beam to be received and irradiated in such a way as to generate a barrier, in particular without the occurrence of any re-directing or several reflections of the laser beam itself.

[0052] According to one aspect of the invention, said at least one laser emitter 300 is configured to emit a single laser beam A comprising a plurality of frequencies that are harmful or repellent for at least one type of insect.Preferably, said plurality of frequencies is emitted simultaneously within the same laser beam A. In other words, the laser beam is of the multifrequency type.

[0053] Advantageously, the emission of a single laser beam comprising a plurality of frequencies makes it possible to act on different types of insects with a single emission, without requiring several emitters and thus several laser beams, with a consequent simplification of the device.

[0054] The containment body 200 comprises at least one window or aperture 210 adapted to enable the exit of said reflected beam Ar, Br, Cr.

[0055] Said window 210 extends circumferentially around said reflective body 400, relative to said rotation axis Y, so as to prevent, to the extent possible, the reflected beam Ar, Br, Cr from being interrupted by parts of the containment body 200 during its rotation.

[0056] In the example in figure 1, since the rotation motor 430 and the emitter 300 are disposed on opposite sides in the containment body 200 and the reflective body 400 is interposed between them, said window 210 does not extend completely around the containment body 200, but rather has an interruption consisting of a connecting part 220 between the two sides of the container 200. It is possible, however, to envisage that said part 220 is transparent to laser beams.

[0057] In the solution in figure 2, the same device 100 as in figure 1 also comprises a glass or covering surface 230 that is transparent to laser beams and completely closes off said window 210 to protect the internal components. Said glass or covering surface 230 preferably has a shape having axial symmetry, for example cylindrical, to ensure that the reflected beam Ar, Br,Cr is incident thereupon orthogonally, without creating effects of beam reflections and refraction.

[0058] The device 100 shown in figures 1 and 2 may be usefully applied in a door or window opening V, or another opening made in a wall P or in a porch, as shown for example in figure 3.

[0059] The containment body 200 of the device 100 is configured to be able to be mounted along a side of the opening, for example on the lintel VI as per figure 3. For example, said containment body 200 comprises a part 220 configured to be fastened onto a side of the opening V.

[0060] It can be envisaged to mount profiles 500 along the sides of the opening, along the trajectory of the reflected beam Ar, Br, Cr, said profiles 500 having for example a U-shaped cross section as shown in figure 3a, i.e. having two lateral walls 510 rising orthogonally from the edge of the opening V, between which the reflected beam Ar enters.

[0061] The device 100 is applied so that the flat surface defined by the reflected beam A is parallel to the wall and positioned inside the opening V. More particularly, the reflected beam A, by rotating as a result of the rotation of the reflective body 400, is incident on all sides of the opening V, thus defining that surface, which occupies the entire opening V, preventing insects from passing through it.

[0062] In order to obtain this effect, the device 100 should be placed with said rotation axis Y set horizontally and orthogonally to the wall P.

[0063] It is possible to obtain the same result of total screening of an opening also if the opening is, for example, formed below the arch of a porch and thus has a much larger size than a window or a normal door. In this case as well, it issufficient to mount the device 100 in any point of the opening, for example at the highest point of the arch, to ensure that the laser beams emitted generate a barrier surface which occupies the whole opening.

[0064] In the solution in figures 4, 4a and 4b, the device 101 is oriented differently and more particularly the rotation axis Y of the reflective body 400 is set vertically, in a direction parallel to or coincident with the emitted beam A, which is emitted upwards. The reflective surface 410 will thus be facing downwards, i.e. towards the ground.

[0065] The device 101 can be suspended at a certain height from the ground, being for example hung from or supported by a pole M.

[0066] Moreover, if the reflective body 400 is positioned with an angle P greater than 45°, the reflected beam Ar will define a conical surface facing downwards, i.e. towards the ground, thus delimiting a conical volume as schematically illustrated in figure 5.

[0067] In this solution, the containment body 201 can be configured differently and in particular it can comprise a circumferential aperture 211 which enables the exit of the reflected beam Ar and may be conveniently closed off with glass or a transparent surface 231, which will preferably be truncated cone-shaped, with a slope such as to be orthogonal to the reflected beam Ar, to avoid beam reflections and refractions.

[0068] It may be envisaged that a truncated cone-shaped deflection surface 310 is disposed inside the containment body 201, in a position facing the reflective body 400, so as to prevent, in the event of an incorrect orientation of the reflective body 400, the reflected beam Ar from becoming vertical and excessively narrowing the conical surface.The solution in figure 6 shows how it is possible to envisage the installation of a deflection structure 600 surrounding said device 201 in order to deflect the reflected beam Ar downwards at a certain distance from the device 101. In this manner, if the reflected beam Ar is only slightly inclined relative to the ground, it can be deflected towards the ground, so that the surface generated by the rotation of the reflected beam Ar and of the deflected beam Ad will go to delimit an even larger volume.

[0069] Such a structure will comprise, for example, profiles 610 with reflective surfaces 620 oriented in such a way that the incident reflected beam Ar will be deviated downwards, as schematically illustrated in figure 6a.

[0070] The insecticidal or repellent device 100 according to the invention can be used in a plurality of applications.

[0071] More specifically, figures 7-22 illustrate some specific, purely illustrative and non-limiting examples of application wherein the insecticidal or repellent device 100 is installed on or associated with different structures, objects or supports, without this implying any limitation of the technical features of the device itself.

[0073] In particular, the device 100 can be mounted on an edge portion of the opening of the refrigerated display counter, through which the food products are introduced into the refrigerated display counter itself. In this manner, the device creates a flat barrier which covers the opening providing access to therefrigerated display counter.
