1 / 9 “CONSTRUCTIVE ARRANGEMENT APPLIED IN A MOSQUITO TRAP-TYPE DEVICE” Technical field

[001] The model reveals an electronic device of the mosquito trap type, especially for gnats, which does not use chemicals that are harmful to humans nor does it depend on spraying systems.

[002] The device is compact and operates autonomously. Its design is intended to attract a greater number of mosquitoes, hinder their escape, and trap them on a sticky surface. State of the art

[003] There are several types of mosquito repellents and traps widely known on the market, each with different methods for attracting and eliminating insects.

[004] For example, traps with electric grids, traps with suction fans, chemical traps with CO2 or synthetic chemicals, and simple adhesive traps are quite well known. In addition, various repellents can be used in electric air fresheners to expel and / or kill mosquitoes from the environment.

[005] In addition to these, several other less well-known devices exist, such as the one in patent document BR MU8701535 of 2009, which claims a trap formed from a cylindrical container, filled with a certain volume of water, on whose edge a truncated conical tube is attachable, equipped with a lower passage surrounded by an oblique projection that prevents the larva from leaving the inside of the trap. Petition 870250079331, dated 04 / 09 / 2025, page 6 / 16 2 / 9

[006] Document CN1048787A of 1989 may also be cited, claiming a mosquito repellent liquid used in electrically heated mosquito repellents. The mosquito repellent liquid is prepared from fortified Bi-na-ming, Yi-bi-tian, chrysanthemum amine acid, sweet wormwood oil, deodorized kerosene and essence according to a defined proportion. It has the advantages of high mosquito repellent effect, low cost and ease of use.

[007] In any case, although effective, the devices and solutions offered today have problems or limitations that compromise their effectiveness or even the health of the consumer.

[008] Devices that use ultraviolet light, usually associated with an electric grid, present several problems. Although they attract some types of mosquitoes, many species, such as Aedes aegypti, are not strongly attracted to UV light, reducing their effectiveness in controlling these insects. In addition, the burning of mosquitoes upon contact with the grid generates annoying noises and unpleasant odors, which can make the use of the device uncomfortable indoors. There is also a safety risk, as exposure to the electrified grid can be dangerous for children and pets. Another negative point is the need for frequent cleaning, since dead insects accumulate at the base of the device.

[009] A fairly common alternative is traps that use a suction system with a fan. In these devices, UV light or, in some cases, chemical substances are used to attract mosquitoes, which are sucked into an internal compartment where they die from dehydration. Although effective, these Petition 870250079331, dated 04 / 09 / 2025, page 7 / 16 3 / 9 traps have some important disadvantages, such as high energy consumption due to the continuous operation of the fan, as well as the noise generated, which can be bothersome, especially in enclosed spaces. Furthermore, the system's efficiency depends on the air circulation generated by the fan, which limits its performance under certain conditions. The need for maintenance is also a relevant factor, since the capture compartments need to be emptied regularly to avoid unpleasant odors.

[010] Another category of traps uses chemical substances, such as carbon dioxide, which can be effective especially in open areas, but have important limitations. The operating cost tends to be high due to the need for constant replenishment of the attractants. In addition, the use of chemical substances can generate environmental and safety concerns, especially in indoor spaces.

[011] Adhesive traps are a simpler and quieter option, equipped with sticky plates where mosquitoes become trapped upon contact. This type of solution, however, depends heavily on the quality of the attraction system to ensure that the insects actually enter the device. Those that use UV light, if the lights are not powerful enough or poorly positioned, the capture is completely ineffective.

[012] It is also known that repellent devices use strong chemicals that are harmful and / or have unpleasant odors to humans, becoming a problem when used continuously. Objectives of the model Petition 870250079331, dated 04 / 09 / 2025, page 8 / 16 4 / 9

[013] The present model aims to provide an efficient and safe solution for capturing mosquitoes and gnats, using a combination of technologies to maximize its effectiveness without compromising user comfort. Unlike many conventional traps, which rely exclusively on UV light or mechanical, sprinkler and / or chemical systems that can cause discomfort, the present device integrates two complementary attraction methods: ultraviolet light, which stimulates insects to approach, and an adhesive chemical solution that mimics human odors, significantly increasing its attraction capacity without the need for sprinklers or toxic substances. These solutions are optimally arranged in the device's casing to achieve maximum effectiveness.

[014] One of the advantages of this device compared to conventional electric traps is the absence of shock grids, eliminating unpleasant noises and preventing the release of odors resulting from the burning of insects. This difference makes the trap more suitable for indoor environments, where silence and discretion are desirable. Furthermore, unlike suction models that use fans to capture mosquitoes, this device does not require an active motor, making its operation completely silent and more energy-efficient. The absence of moving parts also significantly reduces the need for maintenance and the possibility of mechanical failures. The device operates autonomously and only requires the occasional replacement of its adhesive plate.

[015] Unlike conventional sticky traps that rely exclusively on UV light, the inclusion of the odor-inducing attractant enhances mosquito capture by mimicking the signals they use. Petition 870250079331, dated 04 / 09 / 2025, page 9 / 16 5 / 9 are used to locate humans. Because this attractant does not require active dispersion in the air and does not emit unpleasant odors, the device can be used in any environment without causing discomfort to occupants. Furthermore, because it does not use poisons or aggressive chemical agents, it offers a safe approach for homes, commercial establishments, and places where there are children or pets.

[016] Another innovative aspect of the project is the design of the device's entrance, which uses a pattern of angled fins. This structure facilitates the entry of mosquitoes while hindering their exit, ensuring that once inside the device, the insects are retained until they come into contact with the adhesive surface. This structural detail improves the capture rate compared to devices that do not have physical mechanisms to prevent the insects from escaping.

[017] In addition to conventional traps, the device also offers significant advantages over chemical repellents, which often contain potentially harmful substances and need to be reapplied frequently to maintain effectiveness. Because this trap works continuously and without emitting substances into the environment, it provides passive and long-lasting mosquito control without depending on the cooperation of users, who normally need to remember to replenish repellent products in electric air freshener devices.

[018] In summary, the present device stands out for offering a highly effective and discreet solution in mosquito control, eliminating the main limitations of traditional traps and conventional repellent methods. Combining UV light attraction and a chemical attractant integrated into the adhesive layer, coupled with a Petition 870250079331, dated 04 / 09 / 2025, page 10 / 16 The 6 / 9 intelligent design facilitates insect capture without the need for mechanical or electrified elements, representing an innovative and safe approach to mosquito control in various environments.

Detailed description of the model

[019] The device (1) is a type of insect trap, more specifically for mosquitoes and gnats. It consists of a Petition 870250079331, dated 04 / 09 / 2025, page 11 / 16 7 / 9 compact, two-part fairing housing the trap mechanism and exposing the power cable (3) with plug (4). General configuration:

[020] The front part (2a) of the fairing has a window (5) that is semi-closed by a pattern of inclined fins (6).

[021] The rear part (2b) of the fairing has an opening (7) to its interior, closed by an access door (8) by fitting and / or screwing.

[022] Internally, the casing houses a driver (9) or control and power supply circuit, connected to an on / off switch (10) exposed on the casing. The driver (9) is connected to a PCB (11) implemented with a sequence of UV LEDs (12), provided in the device by the ability of ultraviolet light to attract insects. It also houses an adhesive plate (13) with the front face provided with an adhesive layer, provided to capture and hold the insects after they enter the interior of the device (1). Preferred configuration:

[023] Thus defined the general configuration that configures the device in any possible arrangement, the inventor provides the preferred configuration for best use, according to a prototype tested and in perfect working order.

[024] The fins (6) are laminar bodies arranged horizontally, so as to cover the window (5) from one side to the other, maintaining only the openings of the spaces between the fins (6), which are arranged in a downward slope from the inside out. This forms, in the window (5), an upward and facilitated entry for mosquitoes and which makes it difficult Petition 870250079331, dated 04 / 09 / 2025, page 12 / 16 8 / 9 its exit, since the upward flight motion on exit is blocked by the inner face of the angled fins (6).

[025] By means of dedicated supports (14), the rear part (2b) of the fairing supports the PCB (11) in the upper inner portion and in an inclined position, with the LEDs (12) facing towards the window (5). This positioning allows better incidence of ultraviolet light inside the device (1), while at the same time allowing this light to exit in a directed downward manner through the fins (6) of the window (5), which prevents UV light from escaping to other areas of the environment where people are.

[026] Preferably, the adhesive plate (13) is positioned just below the PCI (1 1), occupying almost all of the free portion of the internal space. This improves the capture of insects that enter attracted by the light and odor, in addition to offering sufficient sticky surface. Furthermore, its adhesive layer has a chemical solution of the type that mimics human odor, in order to attract mosquitoes without the need for any spraying mechanism or method.

[027] The adhesive plate (13) is preferably fitted and supported on the access door (8) by means of supports or clamps (15) arranged on its inner face, in order to stabilize the plate (13) and allow its easy and quick fitting and removal. In addition, this face of the door (8) projects a lower base (16) with side flaps (17) which, in addition to supporting the adhesive plate (13), retains any remaining parts of the captured insects, facilitating cleaning. [02 8] Preferably, the rear part (2b) of the fairing has an upper recess (18) for gripping and ease of manual handling and transport of the device (1). How it works: Petition 870250079331, dated 04 / 09 / 2025, page 13 / 16 9 / 9

[029] Thus defined the device (1), it is seen that its operation is autonomous, the user only needs to plug it into the socket and activate the switch (10) to start its function.

[030] With this, both the ultraviolet light from the LEDs (12) and the chemical solution of the adhesive plate (13) begin to attract the mosquitoes, which enter the device (1) through the window (5), guided by the fins (6), where they end up sticking to the adhesive layer of the adhesive plate (13). Those that do not reach the plate (13) immediately have their exit hindered by the inclined position of the fins (6) and will eventually also be captured by the adhesive.

[031] The device's shape (1), i.e., its constructive configuration, joined to the adhesive plate (13) with a chemical that simulates human odor, allows the device to function even when not connected to a power source. Petition 870250079331, dated 04 / 09 / 2025, page 14 / 16
