Description

Technical Field

[0001] This utility model belongs to the technical field of mosquito killing equipment, specifically relating to a negative pressure carbon dioxide internal circulation mosquito killer. Background Technology

[0002] Mosquito bites not only cause itching and allergies, but also pose a significant public health burden and economic losses by spreading pathogens. While mosquitoes play a role in the food chain, their harmfulness far outweighs their ecological value; therefore, scientific mosquito control is a necessary means to balance human health and the environment.

[0003] In the prior art, Chinese invention patent application CN119404821A discloses a highly efficient carbon dioxide recycling device for capturing mosquitoes. In this device, mosquitoes are sucked into a mosquito-catching tube by a fan. The threads on the inner wall of the tube create an air vortex, while a carbon dioxide input structure releases carbon dioxide into the tube to prevent escape. After the mosquitoes are killed by the killing device in the trap, their bodies fall into a detachable collection trough for disposal. The carbon dioxide-rich gas continues to enter the circulation pipe and exits from the outlet. A high-concentration carbon dioxide area is formed between the inlet and the second end of the circulation pipe, continuously attracting mosquitoes. The carbon dioxide-rich gas can then re-enter the inlet, achieving carbon dioxide recycling. However, the aforementioned prior art still relies on a killing device to kill the mosquitoes entering the trap. This device is an electric grid, which generates electric shock noise and ozone when killing mosquitoes.

[0004] Therefore, it is necessary to design a negative pressure carbon dioxide internal circulation mosquito killer that can achieve carbon dioxide recycling and avoid electric shock noise and ozone generation to solve the current technical problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, this utility model provides a negative pressure carbon dioxide internal circulation mosquito killer that can realize the recycling of carbon dioxide and avoid electric shock noise and ozone generation.

[0006] The technical solution of this utility model is as follows: a negative pressure carbon dioxide internal circulation mosquito killer, including a base box, a fan, and an air supply component; the top of the base box is provided with an air return port, and a corresponding air outlet pipe is mounted above the air return port. The upper end of the air outlet pipe is connected to the base box through a ventilation pipe. The interior of the base box is provided with a wind valve connected to the air return port, and a mosquito-collecting net bag is detachably installed at the lower end of the wind valve; the fan is used to drive the gas inside the base box to flow sequentially through the ventilation pipe and the air outlet pipe and then discharge downward from the lower end of the air outlet pipe; the air supply component is used to supply carbon dioxide to the interior of the base box.

[0007] Furthermore, the gas supply assembly includes a controller and a carbon dioxide cylinder. The controller is connected to a solenoid valve and a carbon dioxide sensor. The solenoid valve is used to connect or disconnect the pipeline from which the carbon dioxide cylinder supplies gas to the interior of the base box.

[0008] Furthermore, a mosquito-attracting lamp is provided above the air return port; the mosquito-attracting lamp has a lamp bracket, which is fixedly connected to the top of the base box, and a lamp holder is fixedly provided in the middle of the lamp bracket, with the lamp body provided on the lamp holder.

[0009] Furthermore, a transparent lampshade is fitted onto the outer side of the lamp body, and the lower end of the lampshade is fitted onto the outer side of the lamp holder.

[0010] Furthermore, both the vent pipe and the outlet pipe are transparent.

[0011] Furthermore, the diameter of the return air port is not less than the diameter of the air outlet pipe, and a return air guide tube connected to the return air port is provided at the top inner part of the bottom box. The return air guide tube has a trumpet-shaped structure that is narrow at the bottom and wide at the top, and the air valve is located at the bottom end of the return air guide tube.

[0012] Furthermore, the upper end of the vent pipe is provided with a U-shaped bend that communicates with it, and the top of the bottom box is provided with a connecting pipe head that communicates with its interior. One end of the vent pipe is detachably inserted into the interior of one end of the U-shaped bend, and the other end of the vent pipe is detachably inserted into the interior of the connecting pipe head.

[0013] Furthermore, a baffle is provided on the outside of the air outlet pipe, and the outer diameter of the baffle is not less than the inner diameter of the air return port.

[0014] Furthermore, the interior of the bottom box is equipped with mosquito attractants.

[0015] Furthermore, a door panel is provided on one side of the base box.

[0016] The beneficial effects of this utility model are:

[0017] (1) In this utility model, the gas supply component supplies carbon dioxide to the bottom box. The fan drives the carbon dioxide-containing gas inside the bottom box to flow through the ventilation pipe and the outlet pipe in sequence and then discharges downward from the lower end of the outlet pipe. Most of the gas discharged from the outlet pipe returns to the bottom box through the return port to form an internal circulation, thereby realizing the recycling of carbon dioxide.

[0018] (2) During the internal circulation process, a region with a high carbon dioxide concentration will be formed between the air outlet and the air return port. A small amount of carbon dioxide will inevitably be released outside this region. The carbon dioxide will attract mosquitoes to the region between the air outlet and the air return port. After entering this region, the mosquitoes will be carried into the mosquito collection net bag by the airflow and collected. Under the continuous action of the airflow, the mosquitoes inside the mosquito collection net bag will be dried and die, thus avoiding electric shock noise and ozone generation.

[0019] (3) Before the machine is stopped, there will inevitably be mosquitoes that have not died in the mosquito collection net bag. At this time, the channel above the mosquito collection net bag is sealed by the air valve, and then the fan is stopped. This can prevent the mosquitoes that have not died inside the mosquito collection net bag from flying out when the machine is stopped. Attached Figure Description

Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0027] like Figures 1 to 3 As shown, a negative pressure carbon dioxide internal circulation mosquito killer is disclosed, including a base box 1, a fan 5, and an air supply component 9. A return air port 11 is provided on the top of the base box 1, and a corresponding air outlet pipe 3 is mounted above the return air port 11. The upper end of the air outlet pipe 3 is connected to the base box 1 via a ventilation pipe 2. An air valve 6 connected to the return air port 11 is provided inside the base box 1, and a mosquito net bag 8 is detachably installed at the lower end of the air valve 6. The fan 5 drives the gas inside the base box 1 to flow sequentially through the ventilation pipe 2 and the air outlet pipe 3, and then discharges downwards from the lower end of the air outlet pipe 3. The air supply component 9 supplies carbon dioxide to the interior of the base box 1. In this embodiment, the air supply component 9 supplies carbon dioxide to the interior of the base box 1, and the fan 5 drives the carbon dioxide-containing gas inside the base box 1 to flow sequentially through the ventilation pipe 2 and the air outlet pipe 3, and then discharges downwards from the lower end of the air outlet pipe 3. Most of the gas discharged from the air outlet pipe 3 is returned to the base box 1. The air outlet 11 returns to the interior of the bottom box 1 to form an internal circulation, realizing the recycling of carbon dioxide. During the internal circulation, a region with a high concentration of carbon dioxide will be formed between the air outlet 3 and the air return outlet 11. Inevitably, a small amount of carbon dioxide will be released outside this region. The carbon dioxide is used to attract mosquitoes to the region between the air outlet 3 and the air return outlet 11. After entering this region, the mosquitoes will be carried into the mosquito collection net bag 8 by the airflow for collection. Under the continuous action of the airflow, the mosquitoes inside the mosquito collection net bag 8 will dry out and die, avoiding electric shock noise and ozone generation. Since this device only operates during the period when mosquito killing is needed, there will inevitably be surviving mosquitoes in the mosquito collection net bag 8 before the machine is stopped. At this time, the channel above the mosquito collection net bag 8 is sealed by the air valve 6, and then the fan 5 is stopped, which can prevent the surviving mosquitoes inside the mosquito collection net bag 8 from flying out when the machine is stopped.

[0028] In some embodiments, such as Figure 4As shown, the gas supply assembly 9 includes a controller 91 and a carbon dioxide cylinder. The controller 91 is connected to a solenoid valve 93 and a carbon dioxide sensor 92. The solenoid valve 93 is used to connect or disconnect the pipeline supplying gas from the carbon dioxide cylinder to the bottom chamber 1. The controller 91 has preset upper and lower limits for carbon dioxide concentration. The controller 91 collects the real-time carbon dioxide concentration value inside the bottom chamber 1 through the carbon dioxide sensor 92. When the real-time carbon dioxide concentration value is lower than the preset lower limit, the controller 91 controls the solenoid valve 93 to connect the pipeline supplying gas from the carbon dioxide cylinder to the bottom chamber 1, allowing carbon dioxide gas from the cylinder to enter the bottom chamber 1, increasing the carbon dioxide concentration inside the bottom chamber 1. When the real-time carbon dioxide concentration value is higher than the preset upper limit, the controller 91 controls the solenoid valve 93 to connect the pipeline supplying gas from the carbon dioxide cylinder to the bottom chamber 1, increasing the carbon dioxide concentration inside the bottom chamber 1. At this time, the controller 91 controls the solenoid valve 93 to shut off the pipeline supplying carbon dioxide gas from the carbon dioxide cylinder to the bottom box 1; through the above control method, the carbon dioxide concentration inside the bottom box 1 is maintained within a certain range; more specifically, the preset upper limit of carbon dioxide concentration is 41000ppm and the lower limit is 39000ppm, and the carbon dioxide concentration inside the bottom box 1 is controlled between 39000ppm and 41000ppm; the controller 91 can be implemented by using a microcontroller or PLC in conjunction with an analog-to-digital converter; the carbon dioxide cylinder can also be replaced by a DIY carbon dioxide cylinder or other gas sources that can stably generate carbon dioxide gas; specifically, the DIY cylinder uses carbon dioxide effervescent tablets, the reaction of yeast with sugar, the reaction of citric acid with baking soda, and the reaction of alum with baking soda to generate carbon dioxide.

[0029] In some embodiments, a mosquito-attracting lamp 4 is provided above the air return port 11; the mosquito-attracting lamp 4 has a lamp bracket 41, which is fixedly connected to the top of the base box 1, and a lamp holder 42 is fixedly provided in the middle of the lamp bracket 41, and a lamp body 43 is provided on the lamp holder 42; the mosquito-attracting lamp 4 further enhances the mosquito-attracting effect; the specific lamp body 43 can be a frequency-vibration insecticidal lamp.

[0031] In some embodiments, the ventilation pipe 2 and the exhaust pipe 3 are both transparent structures. The transparent structure of the ventilation pipe 2 and the exhaust pipe 3 can reduce the obstruction of the light of the mosquito-attracting lamp 4 and ensure the mosquito-attracting effect.

[0032] In some embodiments, the diameter of the return air port 11 is not less than the diameter of the air outlet pipe 3. The inner top of the bottom box 1 is provided with a return air guide tube 12 connected to the return air port 11. The return air guide tube 12 is a funnel-shaped structure that is narrow at the bottom and wide at the top. The air valve 6 is provided at the bottom end of the return air guide tube 12. The return air guide tube 12 with a larger opening can collect more carbon dioxide gas flowing out of the air outlet pipe 3, reduce the loss of carbon dioxide gas during the internal circulation process, and at the same time facilitate mosquitoes to enter the mosquito net bag 8 under the action of airflow.

[0033] In some embodiments, such as Figure 2 As shown, the upper end of the air outlet pipe 3 is provided with a U-shaped bend 31 connected to it, and the top of the bottom box 1 is provided with a connecting pipe head 13 connected to its interior. One end of the air pipe 2 can be detachably inserted into one end of the U-shaped bend 31, and the other end of the air pipe 2 can be detachably inserted into the interior of the connecting pipe head 13. The air pipe 2, the bottom box 1 and the air outlet pipe 3 are detachable and can be separated during transportation and connected together using a front-mounted connector.

[0034] In some embodiments, a baffle 7 is provided on the outside of the air outlet pipe 3. The outer diameter of the baffle 7 is not less than the inner diameter of the air return port 11. The baffle 7 can form a shield above the air return port 11, which plays a certain protective role.

[0035] In some embodiments, a mosquito attractant 7 is provided inside the bottom box 1. The mosquito attractant 7 can emit a mosquito-attracting odor during the self-circulation process, further enhancing the mosquito-attracting effect. Specifically, the mosquito attractant 7 is placed in the bottom of the bottom box 1 through a container.

[0036] In some embodiments, a door panel 12 is provided on one side of the base box 1. One side of the door panel 12 is hinged to the base box 1, and the other side of the door panel 12 is locked or opened in cooperation with the base box 1 through a door lock. Opening the door panel 12 allows the mosquito net bag 8 to be replaced. More specifically, the door panel 12 has a transparent structure, which makes it easy to observe the mosquito collection situation inside the mosquito net bag 8 and facilitates timely replacement.

[0037] In some embodiments, a networked camera device can be installed inside the bottom box 1 to facilitate remote observation of mosquito collection inside the mosquito net bag 8. The camera device is equipped with a supplementary light to cope with insufficient light in the bottom box 1.

[0038] In some embodiments, the mosquito-collecting net bag 8 has a net bag body 81, and a rope loop 82 is provided at the opening of the net bag body 81; the lower end of the air valve 6 is fixedly provided with an mounting flange 61 that matches the rope loop 82, and the rope loop 82 can be fixedly fitted on the outside of the mounting flange 61. After a certain amount of mosquitoes are collected inside the mosquito-collecting net bag 8, the rope loop 82 can be removed from the mounting flange 61 for replacement; specifically, the rope loop 82 is an elastic rope loop or a pull-out tie rope loop.

[0039] In some embodiments, the fan 5 can be located inside the base box 1 at a position corresponding to the connecting pipe head 13, or inside the lower end of the air outlet pipe 3; preferably, the fan 5 is located inside the base box 1.

[0040] In the above embodiments, the negative pressure carbon dioxide internal circulation mosquito killer has an on / off state. In the on / off state, the fan 5 and the mosquito-attracting lamp 4 are powered on and started, the air valve 6 is opened, and the air supply component 9 supplies carbon dioxide to the bottom box 1 and maintains the carbon dioxide concentration within a certain range. In the off state, the fan 5 and the mosquito-attracting lamp 4 are powered off and stopped, the air valve 6 is closed, and the air supply component 9 stops supplying carbon dioxide to the bottom box 1. During implementation, the negative pressure carbon dioxide internal circulation mosquito killer can switch between the on / off state by a switch, or it can switch and maintain the on / off state by a preset start time for a fixed period of time within a day, or it can be used with a light intensity sensor to realize the nighttime operation of this device.

[0041] In some embodiments, such as Figure 5 As shown, the lower end of the air outlet pipe 3 has a circular array of air guide plates 32 inside, and the air guide plates 32 are arc-shaped plates.
