Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a carbon dioxide mosquito attracting and killing device. Background Technology

[0002] Mosquitoes are carriers of many pathogens, easily transmitting various diseases including malaria and dengue fever, seriously endangering human health. Currently, widely used chemical mosquito control methods have potential pollution risks, and the impact of prolonged and excessive close contact on human health cannot be ignored.

[0003] Conventional mosquito traps typically use a light source to attract mosquitoes. Once the mosquitoes are attracted to the vicinity of the light source, a fan sucks them into the device, where they are dried out and die. This type of device relies solely on light to attract mosquitoes, making it inefficient, especially during the day.

[0004] To address this, the applicant's earlier patent application (publication number CN215012865U) provides a mosquito trapping device, including a shell, an attraction light source, and a fan. It also includes a carbon dioxide enrichment and release unit, a carbon dioxide releaser, an air duct, and a mosquito storage box. The carbon dioxide enrichment and release unit is fixed to the top inside the shell, the mosquito storage box is fixed to the shell, and the air duct is fixed inside the shell. The air outlet of the air duct is connected to the mosquito storage box, and the air inlet of the air duct faces the bottom of the shell. A fan is fixed inside the air duct, and the attraction light source and carbon dioxide releaser are fixed at the air inlet of the air duct. The carbon dioxide enrichment and release unit releases carbon dioxide gas through the carbon dioxide releaser. This device uses a continuously generating carbon dioxide enrichment and release unit as a gas source, utilizing the attraction of carbon dioxide to mosquitoes to trap and kill them, thus improving mosquito trapping efficiency to some extent. Although the above solution changes the mosquito attraction method, the mosquito killing method still requires sucking the mosquitoes into the device, causing them to dry out and die. Therefore, the overall killing efficiency still needs improvement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a carbon dioxide mosquito attracting and killing device that is more efficient at trapping mosquitoes and is non-toxic and environmentally friendly.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a carbon dioxide mosquito attracting and killing device, including a shell, a carbon dioxide enrichment and release unit and a carbon dioxide releaser. The carbon dioxide enrichment and release unit is fixed on the shell. The carbon dioxide gas outlet on the carbon dioxide enrichment and release unit is connected to the carbon dioxide gas inlet on the carbon dioxide releaser through a gas delivery pipeline system. The carbon dioxide mosquito attracting and killing device also includes an electric grid device. The carbon dioxide releaser is set inside or on the side of the electric grid device.

[0007] Furthermore, the outer casing is also equipped with a fan assembly, an air duct, and a mosquito storage box. The air outlet of the air duct is connected to the mosquito storage box, and the air inlet of the air duct is preferably set downwards. When the fan assembly is working, the airflow in the air duct can flow from the air inlet of the air duct to the air outlet of the air duct. The carbon dioxide releaser is fixed at the air inlet of the air duct.

[0008] Furthermore, the main body of the power grid device is a cage-shaped mesh structure. The power grid device is located at the air inlet of the air duct, and one end of the air inlet of the air duct is connected to the top of the main body of the power grid.

[0009] Furthermore, a lampshade is fixedly installed at the air inlet of the duct. Both the upper and lower ends of the lampshade are open structures. The upper opening of the lampshade is connected to the air inlet of the duct. An attraction light source is fixedly installed inside the lampshade, and an electric grid device is fixedly installed at the lower end of the lampshade.

[0010] Furthermore, a carbon dioxide emitter is installed on the lampshade, and a carbon dioxide gas inlet is located at the top of the lampshade.

[0011] Furthermore, the fan assembly is located on one side of the mosquito storage box, and the fan assembly is not located inside the air duct. The fan assembly is connected to the mosquito storage box through the exhaust duct.

[0012] Furthermore, the outer shell includes a hollow outer shell body, with a lower cover fixedly connected to the bottom of the outer shell body, an openable and closable upper cover connected to the top of the outer shell body, an inner sealing plate fixedly connected to the upper part of the inner cavity of the outer shell body, a mosquito storage box detachably installed on the inner sealing plate, and a carbon dioxide enrichment and release unit and a fan assembly installed inside the outer shell body.

[0013] Furthermore, the carbon dioxide enrichment and release unit includes an exchange chamber shell, a carbon dioxide capture box, a first blower, a second blower, a first duct, and a second duct. A partition is installed inside the exchange chamber shell to divide the shell into a first chamber and a second chamber. The carbon dioxide capture box is installed on the partition and has a first air outlet communicating with the first chamber and a second air outlet communicating with the second chamber. The carbon dioxide capture box contains carbon dioxide capture material and a carbon dioxide release element, which is a heating element, a humidifying element, or a heating and humidifying element. The air inlet of the first blower is connected to the first duct, and the air outlet is connected to the first chamber. The air inlet of the second blower is connected to the second duct, and the air outlet is connected to the second chamber. Solenoid valves for controlling the opening and closing of the pipelines are installed in both the first and second ducts. The carbon dioxide gas outlet is connected to the inner cavity of the exchange chamber shell.

[0014] Furthermore, the end of the first duct furthest from the first blower has its opening facing downwards; the end of the second duct furthest from the second blower also has its opening facing downwards.

[0015] Furthermore, one end of the top cover is rotatably connected to the outer shell body, while the other end is connected to the outer shell body via a magnetic structure.

[0016] Furthermore, the power grid device is equipped with a human infrared sensor, which controls the start and stop of the power grid device.

[0017] Furthermore, it also includes a support rod and a base, with the support rod fixed to the top of the base and the outer shell fixed to the support rod.

[0018] The beneficial effects of this invention are as follows: During implementation, the carbon dioxide emitter releases carbon dioxide gas, attracting mosquitoes to the area where the electric grid device is located, where they are killed by the grid. The electric grid device also has the advantages of stable voltage and silent killing. In the preferred embodiment, the electric grid device is located at the air inlet of the duct. When mosquitoes are attracted to the air inlet area of ​​the duct, they must first pass through the electric grid. Most mosquitoes are killed by the grid, and only a small number enter the duct, eventually drying out and dying in the mosquito storage box, further improving the overall mosquito-catching efficiency. Furthermore, this invention optimizes the layout of the fan assembly and the duct. The fan assembly is no longer located inside the duct but is instead located on one side of the mosquito storage box, which facilitates mosquito entry into the storage box. This invention also optimizes the specific structure of the carbon dioxide enrichment and release unit. When the carbon dioxide enrichment and release unit is not working, closing the solenoid valves in the first and second air ducts can effectively ensure the airtightness of the inner cavity of the exchange chamber shell and increase the release concentration of carbon dioxide gas when the carbon dioxide releaser is working. When working, the first blower and the second blower work alternately, which can improve the efficiency of carbon dioxide enrichment. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the carbon dioxide mosquito attracting and killing device of this utility model includes a shell 4, a carbon dioxide enrichment and release unit 2, and a carbon dioxide releaser. The carbon dioxide enrichment and release unit 2 is fixed on the shell 4. The carbon dioxide gas outlet 28 on the carbon dioxide enrichment and release unit 2 is connected to the carbon dioxide gas inlet 11 on the carbon dioxide releaser through a gas delivery pipeline system. This utility model also includes an electric grid device 3. The carbon dioxide releaser is located inside or on one side of the electric grid device 3. The term "side" should be interpreted broadly, including the upper side, lower side, left side, right side, front side, and rear side. The carbon dioxide releaser can be located on only one side or multiple sides can be arranged simultaneously. The electric grid device 3 can be set independently or on the shell 4. The main body of the electric grid device 3 can have various shapes, such as a cage-like mesh structure or a planar mesh structure. In the cage-like mesh structure design, the carbon dioxide emitter is located inside the electric grid device 3. The emitter releases carbon dioxide gas, which diffuses through the electric grid device 3 and outwards. This attracts mosquitoes, luring them to the electric grid device 3, where they are then electrocuted. In the planar mesh structure design, the carbon dioxide emitter can be located at the top, bottom, or side of the electric grid device 3. It releases carbon dioxide gas, which diffuses through the device, again attracting mosquitoes and luring them to the electric grid device 3, where they are then electrocuted.

[0030] This invention can also be used in conjunction with a suction-type mosquito trapping device. The outer casing 4 is equipped with a fan assembly 9, an air duct 8, and a mosquito storage box 10. The air outlet of the air duct 8 is connected to the mosquito storage box 10, and the air inlet of the air duct 8 faces downwards. When the fan assembly 9 operates, the airflow within the air duct 8 flows from the air inlet to the air outlet. A carbon dioxide emitter is fixed at the air inlet of the air duct 8. During operation, the carbon dioxide emitter continuously releases carbon dioxide gas at the air inlet of the air duct 8. When mosquitoes are lured to the air inlet area of ​​the air duct 8, they must first pass through the electric grid. Most mosquitoes are killed by the grid, and only a small number enter the air duct 8, eventually drying out and dying in the mosquito storage box 10. This significantly improves the overall mosquito-catching efficiency. Of course, the suction-type mosquito trapping device can also be used independently, directly using carbon dioxide gas to attract mosquitoes, which are then captured and killed in the mosquito storage box 10.

[0031] In the embodiment shown in the attached drawings, the main body of the power grid device 3 is preferably a cage-like mesh structure (i.e., it includes a ring-shaped power grid, and the power grid can be arranged in multiple layers at radial intervals). The power grid device 3 is located at the air inlet of the air duct 8, and one end of the air inlet of the air duct 8 is connected to the top of the main body of the power grid. The two can be directly connected or indirectly connected, for example, a lampshade 5 is added in the preferred embodiment of this utility model.

[0032] To further enhance the mosquito attraction effect, this invention includes a lampshade 5 fixedly installed at the air inlet of the duct 8. Both the upper and lower ends of the lampshade 5 are open, with the upper opening connecting to the air inlet of the duct 8. An attraction light source 6 is fixedly installed inside the lampshade 5, and an electric grid device 3 is fixedly installed at the lower end of the lampshade 5. The attraction light source 6 and the carbon dioxide emitter can be controlled independently according to different needs. For example, during the day, only the carbon dioxide emitter can be turned on while the attraction light source 6 is turned off, reducing the energy consumption of the device. At night, both the attraction light source 6 and the carbon dioxide emitter can be turned on simultaneously, working synergistically for better mosquito killing. The on / off control of the carbon dioxide emitter can be achieved by opening and closing the gas delivery pipeline system between the carbon dioxide gas outlet 28 on the carbon dioxide enrichment and release unit 2 and the carbon dioxide gas inlet 11 on the carbon dioxide emitter.

[0033] The carbon dioxide release device is a pipe or canister with holes, mainly used to release carbon dioxide gas at the end of a pipeline. In this invention, the carbon dioxide release device is preferably mounted on the lampshade 5, with the carbon dioxide gas inlet 11 located at the top of the lampshade 5. In this design, the carbon dioxide release device can be a separate component or integrated with the lampshade 5, where the gas channel and carbon dioxide release hole are directly designed on the lampshade 5.

[0034] Preferably, the carbon dioxide enrichment and release unit 2 includes an exchange chamber shell 21, a carbon dioxide capture box 22, a first blower 23, a second blower 24, a first air duct 25, and a second air duct 26. A partition is provided inside the exchange chamber shell 21 to divide the exchange chamber shell 21 into a first chamber and a second chamber. The carbon dioxide capture box 22 is installed on the partition. The carbon dioxide capture box 22 is provided with a first air outlet communicating with the first chamber and a second air outlet communicating with the second chamber. The carbon dioxide capture box 22 is provided with carbon dioxide capture material and a carbon dioxide release element. The carbon dioxide release element is a heating element, a humidifying element, or a heating and humidifying element. The air inlet of the first blower 23 is connected to the first air duct 25, and the air outlet is connected to the first chamber. The air inlet of the second blower 24 is connected to the second air duct 26, and the air outlet is connected to the second chamber. Solenoid valves 27 for controlling the opening and closing of the pipeline are installed in both the first air duct 25 and the second air duct 26. The carbon dioxide gas outlet 28 is connected to the inner cavity of the exchange chamber shell 21. The carbon dioxide capture material is a material that can absorb carbon dioxide from the air and release the adsorbed carbon dioxide under heating and / or humidification conditions, such as ion exchange resin, zeolite molecular sieve, activated carbon, activated alumina, etc. The first blower 23 and the second blower 24 force air to flow within the carbon dioxide capture box 22, ensuring sufficient contact between the air and the carbon dioxide capture material for better carbon dioxide adsorption. Finally, energizing the carbon dioxide release element allows carbon dioxide gas to accumulate in the inner cavity of the exchange chamber housing 21. When not in operation, closing the solenoid valves in the first air duct 25 and the second air duct 26 effectively ensures the airtightness of the inner cavity of the exchange chamber housing 21, preventing carbon dioxide gas from escaping and increasing the carbon dioxide gas release concentration during operation. During operation, alternating operation of the first and second blowers improves the efficiency of carbon dioxide accumulation. The specific control method involves simultaneously opening the solenoid valves in the first duct 25 and the second duct 26, starting the first blower 23, and stopping the second blower 24. The airflow passes sequentially through the first duct 25, the first chamber, the carbon dioxide capture box 22, the second chamber, and the second duct 26. After a set interval, the first blower 23 is turned off, and the second blower 24 is turned on. The solenoid valves in the first duct 25 and the second duct 26 remain open, and the airflow passes sequentially through the second duct 26, the second chamber, the carbon dioxide capture box 22, the first chamber, and the first duct 25. This process is repeated in a cyclical manner.

[0035] Preferably, the end of the first duct 25 furthest from the first blower 23 has its opening facing downwards; the end of the second duct 26 furthest from the second blower 24 also has its opening facing downwards. The electrical control components 13 involved in the device are preferably located at the bottom of the housing 4.

[0036] The fan assembly 9 is preferably located on one side of the mosquito storage box 10, and the fan assembly 9 is not located inside the air duct 8. The fan assembly 9 is connected to the mosquito storage box 10 through the exhaust pipe.

[0037] Preferably, the outer casing 4 comprises a hollow outer casing body 41, a lower cover 42 fixedly connected to the bottom of the outer casing body 41, an openable and closable upper cover 43 connected to the top of the outer casing body 41, an inner sealing plate 44 fixedly connected to the upper part of the inner cavity of the outer casing body 41, a mosquito storage box 10 detachably installed on the inner sealing plate 44, and a carbon dioxide enrichment and release unit 2 and a fan assembly 9 both installed inside the outer casing body 41. The mosquito storage box 10 can be removed for cleaning by opening the upper cover 43.

[0038] The preferred installation method for the top cover 43 is that one end of the top cover 43 is rotatably connected to the outer shell body 41, and the other end is connected to the outer shell body 41 via a magnetic attraction structure. The magnetic attraction structure includes a first magnet and a second magnet, which can be connected and fixed together by magnetic attraction. The first magnet can be installed on the top cover 43, and the second magnet can be installed on the outer shell body 41 or the inner sealing plate 44. With this structure, the opening and closing of the top cover 43 is relatively convenient.

[0039] To ensure safe operation, the electric grid device 3 is equipped with a human infrared sensor. When a person approaches the electric grid, the device automatically cuts off power and restores power after the person leaves, thus ensuring safe mosquito control.

[0040] For ease of use, this utility model also includes a support rod 7 and a base 1. The support rod 7 is fixed to the top of the base 1, and the outer shell 4 is fixed to the support rod 7.
