Description

Technical Field

[0001] This utility model belongs to the technical field of mosquito control equipment, and specifically relates to a mosquito control device. Background Technology

[0002] Summer is the season when mosquitoes are abundant. During the day, mosquitoes bite people, causing unbearable itching. At night, the buzzing of mosquitoes can also affect people's sleep quality.

[0003] To solve the problem of mosquito bites, existing mosquito control devices generally attract mosquitoes by emitting light, and then electrocute them with an electric grid, producing a burning smell. Due to the electric shock, mosquitoes tend to stick to the electric grid and are difficult to clean. In addition, when there are many objects in the environment, they can block the light, preventing mosquitoes from being attracted to the mosquito control device, thus affecting the efficiency and effectiveness of mosquito control.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0035] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0036] like Figures 1 to 4 As shown, a mosquito-killing device in one embodiment of this utility model includes a housing 1, an attractant module 3, and a negative pressure module 4. The housing 1 has a receiving cavity 13 for containing mosquitoes, and the bottom of the housing 1 has a mosquito inlet 14 communicating with the receiving cavity 13. The attractant module 3 is installed on the bottom surface of the housing 1. The negative pressure module 4 is installed inside the housing 1 and communicates with the receiving cavity 13 to generate negative pressure inside the receiving cavity 13. The mosquito inlet 14 is located near the edge of the bottom surface of the housing 1, and the attractant module 3 is located near the center area of ​​the bottom surface of the housing 1.

[0037] Understandably, the attractant module 3 is used to release attractant 32 to the outside world, thereby attracting mosquitoes to fly towards the mosquito killing device. The negative pressure module 4 creates negative pressure in the receiving cavity 13. Even if negative pressure is generated at the mosquito inlet 14 connected to the receiving cavity 13, outside air enters the receiving cavity 13 through the mosquito inlet 14 under the action of negative pressure. Mosquitoes attracted to the vicinity of the mosquito killing device will be carried into the receiving cavity 13 by the airflow when they fly past the mosquito inlet 14, and trapped in the receiving cavity 13. After a period of time, the mosquitoes in the receiving cavity 13 will dry out and die, thus achieving the effect of mosquito killing.

[0038] Specifically, attractant 32 can be a common mosquito attractant on the market. The core principle of mosquito attractants is to induce mosquitoes to gather by releasing specific chemical substances (such as lactic acid, octanol, etc.) or pheromones.

[0039] The housing 1 includes a first housing 11 and a second housing 12. The first housing 11 has a first cavity and a second cavity. The first cavity has a receiving cavity 13. The second housing 12 is mainly used to accommodate and install other components or structures, such as the display screen 7, etc.

[0040] like Figure 1 and Figure 4 As shown, in this embodiment, an air outlet 15 is provided on the side wall of the housing 1, and the negative pressure module 4 is connected to the air outlet 15. A cover 16 is provided on the side wall of the housing 1, covering the air outlet 15. The bottom of the cover 16 has an opening 161 that communicates with the air outlet 15. When the mosquito-killing device of this utility model is used outdoors or in some special environments, such as in rainy weather, the cover 16 can prevent rainwater or other foreign objects from entering the receiving cavity 13 through the air outlet 15.

[0041] like Figure 5 As shown, in other embodiments, the air outlet 15 is located on the top surface of the housing 1, and a baffle 18 protrudes from the top surface of the housing 1, surrounding the air outlet 15. The cover 16 is connected to the top surface of the housing 1 and / or the baffle 18. The air outlet 15 located on the top surface of the housing 1 simplifies the internal airflow structure and increases suction force through negative pressure, allowing the drawn-in carbon dioxide and attractant to diffuse more evenly in multiple directions, expanding the attraction coverage area. Simultaneously, this arrangement also prevents rainwater or other foreign objects from entering the receiving cavity 13 through the air outlet 15. The baffle 18 serves to block rainwater from flowing through the air outlet 15 on the top surface of the housing 1.

[0042] like Figure 1 and Figure 4 As shown, in this embodiment, the mosquito-killing device further includes a support frame 2. The support frame 2 includes a base 22 and a plurality of spaced-apart support columns 21. One end of each support column 21 is connected to the base 22, and the other end is connected to the bottom of the housing 1. The mosquito-killing device is placed on the ground or installed on other components or devices via the support frame 2 at the bottom. In addition to its connecting function, the support frame 2 also serves to keep the bottom surface of the housing 1 away from the ground or other components or devices, thereby creating space for mosquitoes to move around.

[0043] In other embodiments, the mosquito-killing device includes a hanging bracket (not shown in the figure), which is disposed on the side of the housing. The hanging bracket of the mosquito-killing device can be hung on the wall or the side wall of other devices by other structures or existing screws, which is a hanging mosquito-killing device.

[0044] In this embodiment, the mosquito inlet 14 is located near the edge of the bottom surface of the housing 1; in other embodiments, the mosquito inlet 14 is located near the bottom edge of the side surface of the housing 1. Because the attractant module 3 is located near the central area of ​​the bottom surface of the housing 1, the concentration of attractant 32 in the environment around the bottom of the housing 1 will be greater than in other areas. Therefore, in any of the above embodiments, the mosquito inlet 14 is located close to the bottom of the housing 1. When mosquitoes fly towards the attractant module 3 or hover near the attractant module 3, they are more likely to pass through the mosquito inlet 14, thereby increasing the probability of mosquitoes being sucked into the mosquito inlet 14 and improving the mosquito killing effect.

[0045] In this embodiment, the negative pressure module 4 can be a fan. A screen is provided at the connection between the negative pressure module 4 and the receiving cavity 13, and an air outlet 15 is provided on the housing 1. This continuously generates negative pressure in the receiving cavity 13, meaning that with the fan's action, outside air can flow sequentially through the mosquito inlet 14, the receiving cavity 13, the fan, and out through the air outlet 15. The screen can trap mosquitoes in the receiving cavity 13.

[0046] In other embodiments, the housing 1 is provided with a plurality of micro-holes, and the receiving cavity 13 and the negative pressure module 4 are connected through the micro-holes. That is, in addition to connecting the receiving cavity 13 and the negative pressure module 4, the micro-holes can also prevent mosquitoes from entering the negative pressure module 4.

[0047] Furthermore, such as Figure 3 As shown, the mosquito inlet 14 includes a first slit 141 and a second slit 142, which are arranged in parallel. When the negative pressure module 4 is a fan, if the mosquito inlet 14 only includes one slit, the airflow at the mosquito inlet 14 is relatively stable, and mosquitoes can easily adapt to the airflow, making it easy for them to escape. However, the airflow generated by the parallel first slit 141 and second slit 142 will interact with the fan blades during rotation due to the deviation in distance from the fan blades, resulting in a complex gas flow structure, such as turbulence, which makes it difficult for mosquitoes to adapt to the airflow and makes them easier to be sucked into the mosquito inlet 14.

[0048] Furthermore, the mosquito inlet 14 also includes a third slit 143 arranged parallel to the first slit 141 and the second slit 142. The third slit 143 is located between the first slit 141 and the second slit 142, and the width of the third slit 143 is greater than either the first slit 141 or the second slit 142. Because the width of the third slit 143 is greater than either the first slit 141 or the second slit 142, the suction force at the third slit 143 is different from that at either the first slit 141 or the second slit 142. This further increases the complexity of the airflow perpendicular to the length of the slits at the mosquito inlet 14, making it more difficult for mosquitoes to adapt to the airflow and thus easier for them to be sucked into the mosquito inlet 14.

[0049] Furthermore, at least one of the first slit 141, the second slit 142, or the third slit 143 of the mosquito inlet 14 has a serrated edge shape. This allows for different spacing between the slits in the direction perpendicular to the slit length, thereby increasing the complexity of the airflow in the direction parallel to the slit length.

[0050] In other embodiments, the width of the third slit 143 can be equal to the width of the first slit 141 and the second slit 142. Since the airflow environment on the inside and outside sides of the three slits is different, the first slit is in the external environment, and the other side of the third slit is in the internal environment of the attractant module. There will be supplementary airflow from the ground upwards, which can also increase the spatial complexity of the airflow. The effects are different.

[0051] like Figure 3 As shown, this embodiment includes multiple mosquito inlets 14, which surround the projection of the attractant module 3 onto the bottom surface of the housing 1. The mosquito inlets 14 surround the attractant module 3 from multiple directions, maximizing the intake of mosquitoes attracted to the attractant module 3 and improving mosquito control efficiency.

[0052] In other embodiments, the housing 1 may have only one mosquito inlet 14, which is a segmented annular shape. One mosquito inlet 14 can be arranged around the projection of the attractant module 3 on the bottom surface of the housing 1, and multiple slits in the mosquito inlet 14 can be arranged with the same center.

[0053] like Figure 3 As shown, a mosquito-attracting lamp 5 is installed on the bottom surface of the casing 1, located between the attractant module 3 and the mosquito inlet 14. The mosquito-attracting lamp 5 utilizes the phototaxis of mosquitoes towards specific wavelengths of light, such as ultraviolet light (365-400nm wavelength) or blue light (some models use 420nm monochromatic light). In this embodiment, the mosquito-attracting lamp 5 can be a commercially available 365nm mosquito-killing lamp (i.e., the wavelength of the emitted light is 365nm).

[0054] It is understood that the mosquito inlet 14 in this embodiment is located on the bottom surface of the housing 1. When mosquitoes are attracted to the nearby area by the attractant module 3, the light of the mosquito lamp 5 can further attract mosquitoes to fly towards the mosquito lamp 5, thereby bringing the mosquitoes closer to the bottom surface of the housing 1. When the mosquitoes hover near the bottom surface of the housing 1, they are more likely to be sucked in by the mosquito inlet 14, thereby improving the mosquito killing efficiency.

[0055] Specifically, the mosquito-attracting lamp 5 includes multiple UV LED beads arranged parallel to the mosquito inlet 14. This arrangement ensures that mosquitoes flying towards the UV LED beads pass through the mosquito inlet 14 as much as possible, making it easier for them to be sucked in, thereby improving mosquito-killing efficiency. It is understood that in this embodiment, four mosquito-attracting lamps 5 are installed on the bottom surface of the housing 1, each corresponding to one mosquito inlet 14. In other embodiments, the number and shape of the mosquito-attracting lamps 5 can be adjusted according to requirements, such as circular, room-shaped, etc.

[0056] like Figures 1 to 4 As shown, the attractant module 3 includes a mounting base 31 and an attractant 32 detachably mounted on the mounting base 31. The mounting base 31 is connected to the bottom surface of the housing 1. When the attractant 32 is used up, the attractant 32 can be replaced directly without replacing the entire attractant module 3. In this invention, the attractant 32 refers to a commercially available attractant product (with a container), that is, the attractant product includes a box and the attractant 32 placed inside the box.

[0057] like Figure 4 As shown, the mosquito-killing device in this embodiment also includes a carbon dioxide release mechanism 6, which includes a carbon dioxide gas source 61 and a connecting pipe 62. A carbon dioxide outlet 17 is located at the bottom of the housing 1, and the carbon dioxide gas source 61 is connected to the carbon dioxide outlet 17 via the connecting pipe 62. This arrangement ensures that the carbon dioxide concentration around the mosquito-killing device is higher than the carbon dioxide concentration in other areas of the environment. Even if the carbon dioxide concentration near the bottom of the housing 1 increases to the concentration caused by human respiration, mimicking the human breathing process, it attracts mosquitoes to the mosquito-killing device, luring them as close as possible to the bottom surface (i.e., the bottom) of the housing 1, where they are inhaled through the mosquito inlet 14. The carbon dioxide gas source 61 can be housed within the second housing 12.

[0058] Preferably, the carbon dioxide outlet 17 is positioned towards the attractant module 3, and the attractant module 3 is adjacent to the carbon dioxide outlet 17. This configuration allows the carbon dioxide airflow to propagate the attractant 32, thus increasing its travel distance. Furthermore, the intermittent release of carbon dioxide gas from the carbon dioxide source 61 is an adiabatic expansion process, causing a decrease in the temperature of the released gas. This cools the attractant module and generates condensation near the attractant 32, further increasing its wettability and enhancing its attractant effect.

[0059] In other embodiments, the connecting pipe 62 can also pass through the carbon dioxide outlet 17 and the attractant module setting 3, which can also achieve a similar effect to this embodiment.

[0060] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics.
