Description

Technical Field

[0001] This invention belongs to the field of mosquito egg trapping technology, and particularly relates to a green mosquito egg trapping device. Background Technology

[0002] Mosquitoes belong to the Culicidae family of the suborder Longhornella of the order Diptera. They are recognized as the deadliest animals in the world. They not only suck blood, but also act as vectors for many serious infectious diseases (such as malaria and yellow fever), causing millions of deaths on Earth every year and seriously threatening human health. Mosquitoes cannot grow and reproduce without water. Female mosquitoes rely on their sense of smell, sight and touch to identify environmental factors and choose suitable water bodies as their egg-laying sites and habitats. Currently, there are some mosquito control devices on the market that target mosquito eggs at the source. For example, Chinese utility model patent CN215454845U discloses a device for attracting and killing mosquito eggs. This device attracts mosquitoes to a water tray to lay eggs, and then mixes the water containing the mosquito eggs with an ovicidal agent to kill the mosquito eggs. This controls the growth and survival of mosquitoes at the source, avoids the production and harm of adult mosquitoes, and effectively prevents mosquito pests. However, it requires the use of chemical agents such as ovicidal agents to kill mosquito eggs, which is not green and environmentally friendly. In addition, it also has the drawbacks of having a relatively complex device structure and difficulty in automatically performing the egg-killing operation. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a green mosquito egg trapping device. The device has a simple structure, a green and environmentally friendly mosquito killing method, and can carry out automatic mosquito egg trapping operations for a long time.

[0004] The objective of this invention is achieved through the following technical solution: A green mosquito egg-trapping device includes a support column and a solar panel mounted on top of the support column. A water tank and an egg-laying attraction cup are also mounted on the support column, arranged sequentially from high to low. The water tank contains a water injection pipe connected to the egg-laying attraction cup. The egg-laying attraction cup contains an egg-laying attraction component immersed in water, which has a receiving tray for collecting mosquito eggs. A solenoid valve is mounted on the water injection pipe. The egg-laying attraction cup contains a control component connected to the solar panel and the solenoid valve to control the water level in the cup so as not to exceed the receiving tray.

[0005] In one embodiment, the control component includes an infrared transmitter and an infrared receiver arranged relatively flush, the infrared receiver being electrically connected to the solenoid valve to control the solenoid valve to open when the infrared receiver receives infrared light output from the infrared transmitter, thereby injecting water into the spawning attraction cup; This embodiment utilizes an infrared transmitter and receiver positioned flush against each other to control a solenoid valve, thereby controlling the opening and closing of the water inlet pipe. It cleverly leverages the refraction of infrared light in water to control the water level in the spawning lure cup. When the water level is high, the infrared light emitted by the transmitter is refracted by the water surface, and the receiver cannot receive it, causing the solenoid valve to close and stopping water injection. Conversely, when the water level drops due to evaporation, the infrared light emitted by the transmitter is not refracted, and the receiver receives it, opening the solenoid valve to inject water into the spawning lure cup. This allows for real-time control of the water level in the spawning lure cup without requiring a complex structure, automatically maintaining the spawning paper's moisture level for extended periods and ensuring the water level in the spawning lure cup does not exceed the height of the receiving tray.

[0006] In one embodiment, the oviposition component includes a cotton swab and an oviposition paper sleeved on the cotton swab. The cotton swab is vertically positioned inside the oviposition attractant cup, and the water injection tube is connected to the bottom of the oviposition attractant cup to keep the oviposition paper moist. In this embodiment, the water injection tube is set at the bottom of the oviposition attracting cup. While injecting water into the oviposition attracting cup, water is avoided from being spilled on the eggs. At the same time, the cotton swab is used to continuously absorb the water in the oviposition attracting cup, so that the oviposition paper covered with the cotton swab remains moist, thereby attracting female mosquitoes to lay their eggs on the oviposition paper. In one embodiment, the receiving plate is mounted horizontally on the cotton swab, and the receiving plate is higher than the infrared transmitter and the infrared receiver.

[0007] In one embodiment, the device further includes a chuck mounted horizontally on the cotton swab, the chuck being located below the receiving plate, an infrared receiver mounted on the chuck, and an infrared emitter mounted on the inner wall of the spawning inducing cup.

[0008] In one embodiment, the control assembly further includes a power source electrically connected to the solar panel, the power source being connected to the infrared receiver, the infrared receiver being connected to a resistor and a transistor, the transistor being connected to the solenoid valve to open the solenoid valve when the infrared receiver receives infrared light output from the infrared transmitter.

[0009] In one embodiment, the bottom of the spawning lure cup is further provided with a tray connected to the support column. The tray is provided with a buckle for fixing the cover. The top of the cover is provided with a through hole corresponding to the spawning lure cup. The power supply, the resistor, and the transistor are all provided on the tray and located in the gap between the cover and the spawning lure cup.

[0010] In one embodiment, a rain shelter is provided above the spawning lure cup to prevent rainwater from entering the spawning lure cup, and the rain shelter is installed on the support column.

[0011] In one embodiment, the volume of the water tank is greater than 20 times the volume of the spawning lure cup.

[0012] In one embodiment, the rain shelter has an arc-shaped structure, and the diameter of the rain shelter is larger than the diameter of the spawning lure cup.

[0013] The beneficial effects of this invention are as follows: Powered by solar panels, the device can be easily installed in mosquito-prone outdoor environments. A water tank, much larger than the egg-laying bait cup, is used to fill the cup, maintaining a constant water environment. The cotton swabs inside continuously absorb water, keeping the egg-laying paper attached to them moist, attracting numerous female mosquitoes to lay their eggs. A collection tray on the cotton swabs catches eggs that fall from the swabs and are dropped by the female mosquitoes. When the water level in the egg-laying bait cup is high, the infrared rays emitted by the infrared transmitter are refracted by the water surface, preventing the infrared receiver from receiving the emitted rays. When the solenoid valve closes, it stops adding water to the egg-laying attractant cup. As the water level drops below the infrared emitter due to evaporation, the emitted infrared rays do not refract. The infrared receiver, positioned opposite the emitter, receives the infrared rays, and the solenoid valve opens to add water to the egg-laying attractant cup. This automatically keeps the egg-laying paper moist for a long time and ensures that the water level in the attractant cup does not exceed the height of the receiving tray. This attracts female mosquitoes to lay eggs while preventing the eggs from entering the water, thus preventing the eggs from hatching. The rain shelter above the attractant cup prevents rainwater from affecting the water level. Only periodic manual addition of water to the storage tank is needed for green and automatic mosquito control at the source. Attached Figure Description

Detailed Implementation

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] This invention provides a green mosquito egg-trapping device, such as... Figure 1 and Figure 2 As shown, the device includes a support column 1 and a solar panel 4 mounted on top of the support column 1. A water tank 2 and an egg-laying attraction cup 7 are also mounted on the support column 1, arranged sequentially from high to low. The water tank 2 contains a water injection pipe 6 connected to the egg-laying attraction cup 7, and a solenoid valve 10 is mounted on the water injection pipe 6. The egg-laying attraction cup 7 contains an egg-laying attraction component, which includes a chuck 17 for securing a cotton swab 19. A cotton swab 19 draws water from the egg-laying cup onto the egg-laying paper; a receiving tray 18 catches mosquito eggs that fall from the egg-laying paper; an infrared transmitter 8 and an infrared receiver 9 are installed on the outer wall of the egg-laying attractant cup 7 to control the water level; the infrared emission and reception are controlled by the control components on the tray 16 to control the opening and closing of the solenoid valve 10 to ensure that the water level in the egg-laying attractant cup 7 is not higher than the chuck 17; a cover 3 is installed on the outside of the egg-laying attractant cup 7 to protect the solenoid valve 10 and its control components. It should be noted that in this embodiment, the entire device is supported and installed using a support column 1. A solar panel 4 mounted on top of the support column 1 provides power, and a power supply 12 stores the power provided by the solar panel 4 and supplies power to the solenoid valve 10 and its control components. The water tank 2 is used to fill the oviposition attractant cup 7 with water when needed, keeping the cotton swab 19 continuously moist to attract female mosquitoes to lay eggs on the filter paper in the oviposition attractant cup 7. A receiving tray 18 separates the water surface from the mosquito eggs, preventing hatching. The control components adjust the water level in the oviposition attractant cup 7 in real time to ensure the water level does not exceed the level of the chuck 17. Only periodic manual replacement of the oviposition filter paper and adding water to the water tank 2 are required for green and automatic mosquito control at the source.

[0018] Specifically, such as Figure 2 and Figure 3As shown, the control component includes an infrared transmitter 8 and an infrared receiver 9 arranged relatively flat. The infrared receiver 9 is electrically connected to a solenoid valve 10 to control the solenoid valve 10 to open when the infrared receiver 9 receives the infrared light output by the infrared transmitter 8, so as to inject water into the spawning inducer cup 7. It should be noted that the solenoid valve 10 is controlled by the relatively flush infrared transmitter 8 and infrared receiver 9, which in turn control the opening and closing of the water injection pipe 6. This cleverly utilizes the phenomenon of infrared light refraction in water to control the water level in the spawning lure cup 7. Specifically, when the water level in the spawning lure cup 7 is high, the infrared light emitted by the infrared transmitter 8 is refracted by the water surface, and the infrared receiver 9, positioned opposite it, cannot receive the emitted infrared light. The solenoid valve 10 closes, stopping the injection of water into the spawning lure cup 7. Conversely, when the water level decreases due to evaporation, the infrared light emitted by the infrared transmitter 8 does not refract, and the infrared receiver 9 receives the infrared light. The solenoid valve 10 then opens, injecting water into the spawning lure cup 7. This allows for real-time automatic regulation of the water level in the spawning lure cup 7 without the need for a complex structure.

[0019] In one embodiment, the spawn-inducing component includes a cotton swab 19 and an spawn-inducing paper fitted over the top of the cotton swab 19. The cotton swab 19 is vertically positioned inside the spawn-inducing cup 7. The water in the spawn-inducing cup 7 keeps the spawn-inducing paper at the top of the cotton swab 19 moist due to the water absorption of the cotton swab. The water injection pipe 6 is connected to the bottom of the spawn-inducing cup 7 to ensure the water level in the spawn-inducing cup 7. The cotton swab 19 is fixed by a base 20 set on the tray 16. It should be noted that the water injection pipe 6 is located at the bottom of the oviposition attractant cup 7. While injecting water into the oviposition attractant cup 7, avoid spilling water onto the receiving tray 18 and allowing it to come into contact with the mosquito eggs. At the same time, the cotton swab 19 continuously absorbs the water in the oviposition attractant cup 7, keeping the oviposition paper covered by the cotton swab 19 moist, so as to attract female mosquitoes to lay their eggs on the oviposition paper. In one embodiment, black oviposition attractant cups 7 and black oviposition paper can be used to attract more female mosquitoes to lay eggs. In one embodiment, such as Figure 2 As shown, it also includes a chuck 17 mounted horizontally on the cotton swab 19, located below the receiving plate 18. The infrared transmitter 8 and infrared receiver 9 are mounted on the outer wall of the spawning inducing cup 7, and are below the height of the chuck 17. The circular protrusions at the bottom of the chuck 17 and the spawning cup keep the cotton swab 19 upright at all times.

[0020] In one embodiment, such as Figure 3 and Figure 4As shown, the control assembly also includes a power supply 12 electrically connected to the solar panel 4. The power supply 12 is connected to the infrared transmitter 8 and the infrared receiver 9. The infrared receiver 9 is connected to a resistor 14 and a transistor 13. The transistor 13 is connected to a solenoid valve 10 to open the solenoid valve 10 when the infrared receiver 9 receives the infrared light output by the infrared transmitter 8. Furthermore, the solenoid valve 10 is also connected in parallel with a freewheeling diode 11; It should be noted that, as Figure 3 and Figure 4 As shown, the water level in the spawning lure cup 7 will decrease as the water evaporates. When it decreases to a level where the infrared receiver 9 can receive the infrared rays emitted by the infrared transmitter 8, the OUT pin of the infrared receiver 9 outputs a high voltage, the transistor 13 is turned on, and the solenoid valve 10 is energized, opening the solenoid valve 10 on the water injection pipe 6 to inject water into the spawning lure cup 7, maintaining a water environment in the spawning lure cup 7, that is, keeping the spawning paper moist. The water level in the spawning lure cup 7 will rise as the water tank 2 injects water. When the water level rises to a level where the infrared rays emitted by the infrared transmitter 8 are refracted through the water surface, the infrared receiver 9 cannot receive the emitted infrared rays. At this time, the OUT pin of the infrared receiver 9 outputs a low voltage, the transistor 13 is turned off, that is, the valve of the solenoid valve 10 is closed, stopping the water injection. The freewheeling diode 11 is used to avoid the occurrence of surge voltage to protect the solenoid valve 10. In one embodiment, such as Figure 1 and Figure 3 As shown, the bottom of the egg-laying lure cup 7 is also provided with a tray 16 connected to the support column 1. The tray 16 is provided with a buckle 15, which is used to fix the cover 3. The top of the cover 3 is provided with a through hole corresponding to the egg-laying lure cup 7. The power supply 12, resistor 14 and transistor 13 are all provided on the tray 16 and located in the gap between the cover 3 and the egg-laying lure cup 7. In one embodiment, such as Figure 1 As shown, a rain shelter 5 is also provided above the spawning attractant cup 7 to prevent rainwater from entering the spawning attractant cup 7. The rain shelter 5 is installed on the support column 1. Specifically, the rain shelter 5 has an arc-shaped structure, and the diameter of the rain shelter 5 is larger than the diameter of the egg-laying attractant cup 7, so as to avoid rainwater in the environment from affecting the water level in the egg-laying attractant cup 7 and ensure the mosquito killing effect. In one embodiment, the volume of the water tank 2 is greater than 20 times the volume of the egg-laying attractant cup 7, which ensures that the device can carry out automatic mosquito egg killing operations for a long time. Water can be manually added to the water tank 2 at intervals. The specific capacity of the water tank 2 can be set according to environmental conditions, manual operation conditions, and the load of the support column 1. In one embodiment, the working principle of the present invention is as follows: like Figures 1 to 4 As shown, this device is powered by a solar panel 4, making it easy to place in outdoor environments with high mosquito populations. A water tank 2, with a capacity much larger than the egg-laying attractant cup 7, is used to fill the cup, maintaining a consistently wet environment. The cotton swab 19 in the cup continuously absorbs water, keeping the egg-laying paper attached to it moist, attracting a large number of female mosquitoes to lay their eggs. Since the egg-laying paper is not submerged, the mosquito eggs cannot hatch properly. The receiving tray 18 on the cotton swab 19 receives eggs falling from it and those dropped by the female mosquitoes. When the water level in the attractant cup 7 is high, the infrared rays emitted by the infrared emitter 8 are refracted by the water surface, causing the infrared rays emitted by the emitter to reflect off the surface. When the infrared receiver 9 fails to receive the emitted infrared rays, the solenoid valve 10 closes to stop water from being added to the egg-laying attractant cup 7. When the water level drops below the infrared transmitter 8 due to evaporation, the emitted infrared rays do not refract, and the infrared receiver 9, which is positioned opposite to it, receives the infrared rays. The solenoid valve 10 then opens to add water to the egg-laying attractant cup 7. This automatically keeps the egg-laying paper moist for a long time and ensures that the water level in the egg-laying attractant cup 7 does not exceed the height of the receiving tray 18. This attracts female mosquitoes to lay eggs while preventing mosquito eggs from entering the water, thus preventing the mosquito eggs from hatching. The rain shelter 5 above the egg-laying attractant cup 7 prevents rainwater from affecting the water level in the egg-laying attractant cup 7. Only manual periodic replacement of the egg-laying paper and adding water to the water storage tank 2 are needed to achieve green and automatic mosquito control from the source.
