This dual safety structure reduces the risk of electric shock and improves the safety and reliability of the device when used in homes, public places, and other scenarios.

Description

Technical Field

[0001] This invention relates to the field of mosquito capture and control technology, and in particular to a mosquito trapping device based on mosquito control. Background Technology

[0002] Mosquito trapping refers to mosquito control technologies and devices that utilize the natural attraction of mosquitoes to factors such as light, color, smell, temperature, carbon dioxide, and airflow to actively attract mosquitoes to a limited area through a lure, and then capture, kill, or collect them using physical or chemical methods such as electric shock, sticky trap, wind suction, blocking, or poisoning.

[0003] Most mosquito traps currently on the market have protective nets installed outside the electric shock or killing area. However, the mesh spacing of these nets is generally large, which only provides a preliminary shielding effect and cannot effectively prevent human fingers from entering. During daily use, cleaning, maintenance, or when children touch them, fingers can easily be accidentally inserted into the internal electrified or high-temperature working area, leading to electric shock, burns, and other safety risks. Overall, the safety protection performance is insufficient, and there are obvious hidden dangers and structural defects.

[0004] Therefore, it is necessary to design a mosquito-trapping device based on mosquito control to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mosquito-trapping and killing device based on mosquito control.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mosquito-trapping and killing device includes a housing and two UV LED lights disposed on the inner wall of the housing. A protective net is disposed on the inner wall of the outer opening end of the housing, and a killing net is disposed on the inner wall of the housing between the protective net and the UV LED lights. An installation structure corresponding to the protective net and the killing net is disposed on the inner top surface of the housing. A slot is opened on the top side of the housing, and two sets of clearance components for driving the installation structure are symmetrically disposed on the inner side of the slot. An operating structure for operating the two sets of clearance components is disposed on the side of the housing. A protective component linked to the protective net is disposed at the outer opening end of the housing. The installation structure includes a guide groove 1 on the inner top surface of the outer shell, an installation plate 1 slidably mounted on the inner wall of the guide groove 1, and a protective net fixedly mounted on the bottom surface of the installation plate 1. A guide groove 2 is provided on the inner top surface of the outer shell, an installation plate 2 slidably mounted on the inner wall of the guide groove 2, and a killing net fixedly mounted on the bottom surface of the installation plate 2. Two guide openings communicating with the grooves are symmetrically provided on the inner top surfaces of both the guide groove 1 and the guide groove 2.

[0007] As a preferred embodiment of the present invention, the clearance assembly includes a shaft rotatably mounted on the bottom surface of the slot, a transmission gear fixedly fitted on the outer wall of the shaft, a drive gear fixedly fitted on the outer wall of the shaft above the transmission gear, a torsion spring I fitted on the bottom end of the shaft, and the two ends of the torsion spring I being fixedly connected to the shaft and the bottom surface of the slot, respectively. A connecting plate I is fixedly mounted on the top surface of the mounting plate I, and a drive rack meshing with the drive gear is fixedly mounted on the top end of the connecting plate I through a guide opening. A connecting plate II is fixedly mounted on the top surface of the mounting plate II, and a transmission rack meshing with the transmission gear is fixedly mounted on the top end of the connecting plate II through a guide opening.

[0008] In a preferred embodiment of the present invention, the number of teeth on the transmission gear is greater than the number of teeth on the drive gear.

[0009] As a preferred embodiment of the present invention, the operating structure includes a reel fixedly installed at the top of the shaft, a connecting rope provided on the inner side of the reel, a pull rope slidably installed on the side of the housing, and the pulling end of the connecting rope passing through the side of the housing and fixedly connected to the pull rope, and a guide wheel corresponding to the pull rope rotatably installed on the side of the housing.

[0010] As a preferred embodiment of the present invention, a pull plate is fixedly installed at the pulling end of the pull rope, and the guide wheel is located at the top corner of the outer casing.

[0011] As a preferred embodiment of the present invention, the protective assembly includes two connecting shells symmetrically and fixedly installed on the outer opening of the outer shell. The inner walls on both sides of the outer shell are provided with communicating grooves that communicate with the connecting shells. A plurality of rotating rods arranged in a linear array are rotatably installed on the inner wall of the communicating groove. A protective plate is fixedly installed on the outer wall of the rotating rods. A transmission structure is provided on the plurality of rotating rods.

[0012] As a preferred embodiment of the present invention, the transmission structure includes several transmission discs fixedly mounted on the outer walls of several rotating rod ends, the several transmission discs being connected by transmission bars, and a torsion spring II being mounted on the outer wall of the top rotating rod away from the transmission disc, and the two ends of the torsion spring II being fixedly connected to the rotating rod and the inner wall of the connecting groove, respectively.

[0013] As a preferred embodiment of the present invention, a slot is provided on the outer wall of the end of the rotating rod away from the second torsion spring, and a card plate is fixedly installed at the end of the protective net to engage with the slot.

[0014] As a preferred embodiment of the present invention, the width of the protective plate is the same as the vertical gap of the protective net, and the initial position of the protective plate is horizontal.

[0015] As a preferred embodiment of the present invention, an insect collection box is provided on the bottom side of the outer shell.

[0016] The present invention has the following beneficial effects: 1. This invention is flexible and convenient to use. The outer shell can be easily hung in a designated position according to the mosquito activity area to ensure the mosquito-attracting coverage. The UVLED lamp and the killing net work together to attract and safely capture mosquitoes, resulting in high mosquito-killing efficiency. The entire device serves as a substitute for insecticide, making it more efficient and environmentally friendly. The device is equipped with an insect collection box at the bottom to collect mosquito carcasses. Combined with the vibrating and cleanable killing net design, the sticky insects can be shaken off by reciprocating sliding without complicated disassembly, simplifying the daily cleaning and maintenance process, reducing operating costs, and improving the convenience and practicality of continuous use of the device. 2. When a person accidentally touches the protective net with their finger, the protective net can drive the mounting plate to slide, and through the transmission of the clearance component, the killing net slides away from the finger by a greater distance in the same direction, avoiding the finger from contacting the internal killing net and reducing the safety risk. At the same time, the push force of the accidental touch can simultaneously trigger the protective component, and the protective plate rotates quickly to contact the back of the hand to form a physical reminder, guiding the person to withdraw their finger in time. The dual safety structure reduces the risk of electric shock and improves the safety and reliability of the equipment when used in home, public places and other scenarios. 3. During non-use periods such as winter, the present invention can close the protective plate by pushing the protective net to cover the inside, effectively blocking dust and debris from entering the equipment. This prevents dust accumulation on the UV LED lights and the killing net from affecting the mosquito attraction and electric shock effect, thus extending the service life of the equipment. The protective plate reset operation is simple and does not affect normal mosquito killing and cleaning work. It realizes an integrated design of use, protection, and dustproof storage, and is suitable for different seasons and usage environments. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: This example describes a mosquito-trapping device based on mosquito control, as disclosed in this embodiment. Figure 1-8 The device includes an outer shell 1 and two UV LED lights 2 installed on the inner wall of the outer shell 1. A protective net 3 is installed on the inner wall of the outer opening end of the outer shell 1. A killing net 4 is installed on the inner wall of the outer shell 1 between the protective net 3 and the UV LED lights 2. An installation structure 5 corresponding to the protective net 3 and the killing net 4 is installed on the inner top surface of the outer shell 1. A slot 6 is opened on the top side of the outer shell 1. Two sets of clearance components 7 for driving the installation structure 5 are symmetrically arranged on the inner side of the slot 6. An operating structure 8 for operating the two sets of clearance components 7 is provided on the side of the outer shell 1. A protective component 9 linked with the protective net 3 is provided at the outer opening end of the outer shell 1. An insect collection box 10 is provided on the bottom side of the outer shell 1. The mounting structure 5 includes a guide groove 51 on the inner top surface of the outer shell 1. A mounting plate 52 is slidably installed on the inner wall of the guide groove 51, and a protective net 3 is fixedly installed on the bottom surface of the mounting plate 52. A guide groove 53 is provided on the inner top surface of the outer shell 1. A mounting plate 54 is slidably installed on the inner wall of the guide groove 53, and a killing net 4 is fixedly installed on the bottom surface of the mounting plate 54. Two guide openings 55 communicating with the slot 6 are symmetrically provided on the inner top surfaces of both the guide groove 51 and the guide groove 53.

[0021] The implementation principle of this embodiment is as follows: When in use, users can easily hang the outer shell 1 of the device at the designated location according to their actual needs, ensuring that the device can effectively cover the area where mosquitoes are active. Using the entire device as an insecticide substitute makes it more effective. When the device is working, the UVLED lamp 2 automatically turns on and emits light of a specific wavelength to attract mosquitoes. At the same time, the killing net 4 is powered on and in working condition. Under the light attraction of the UVLED lamp 2, mosquitoes will actively pass through the protective net 3 on the outer shell 1 and enter the interior of the outer shell 1. When the mosquitoes come into contact with the killing net 4, the killing net 4 can capture and kill the mosquitoes. If someone accidentally touches the protective net 3 during daily use, at the moment of contact, the finger passing through the net 3 will exert a certain pushing force on it. Under this pushing force, the mounting plate 52 connected to the net 3 can slide smoothly along the guide groove 51. As the mounting plate 52 slides, it will drive the mounting plate 54 and the extermination net 4 fixedly connected to the mounting plate 54 to slide in the same direction for a greater distance in the guide groove 53 through the transmission action of the clearance component 7. This effectively clears the finger, making it less likely for the finger segment passing through the net 3 to come into contact with the energized extermination net 4, thus maximizing the protection of the finger and avoiding the risk of electric shock. At the same time, when the finger of the person who accidentally touches the net 3 exerts a pushing force on it, this force will simultaneously trigger the protective component 9 on the equipment. The protective component 9 will immediately act on the finger of the person who accidentally touches the net 3, promptly reminding the person of the current risk of electric shock and guiding them to quickly withdraw their finger, further improving the safety of the equipment. In addition, after mosquitoes are electrocuted by the killing net 4, they may excrete body fluids. These fluids can easily stick to the killing net 4. Long-term accumulation can not only affect the electrocution effect of the killing net 4, but also breed bacteria. Therefore, when cleaning the dead mosquitoes on the killing net 4, the user can operate the operating structure 8 on the device and use the clearance component 7 to make the killing net 4 slide back and forth. The vibration generated during the sliding process will shake off the dead mosquitoes stuck to the killing net 4. The shaken-off dead mosquitoes will then fall into the insect collection box 10 at the bottom of the device for centralized collection. The user only needs to take out the insect collection box 10 periodically to clean the dead mosquitoes in the box, which simplifies the daily maintenance process of the device and improves the convenience of use.

[0022] Example 2: Based on Example 1, this example discloses a mosquito-trapping device for insect control, such as... Figure 3-6 As shown, the clearance assembly 7 includes a shaft 71 rotatably mounted on the bottom surface of the slot 6. A transmission gear 72 is fixedly fitted on the outer wall of the shaft 71. A drive gear 73 is fixedly fitted on the outer wall of the shaft 71 above the transmission gear 72. The number of teeth of the transmission gear 72 is greater than the number of teeth of the drive gear 73. A torsion spring 74 is fitted on the bottom end of the shaft 71, and the two ends of the torsion spring 74 are fixedly connected to the shaft 71 and the bottom surface of the slot 6, respectively. A connecting plate 75 is fixedly mounted on the top surface of the mounting plate 52. The top end of the connecting plate 75 passes through the guide opening 55 and is fixedly mounted with a drive rack 76 that meshes with the drive gear 73. A connecting plate 77 is fixedly mounted on the top surface of the mounting plate 54. The top end of the connecting plate 77 passes through the guide opening 55 and is fixedly mounted with a transmission rack 78 that meshes with the transmission gear 72. The operating structure 8 includes a reel 81 fixedly installed at the top of the shaft 71. A connecting rope 82 is provided on the inner side of the reel 81. A pull rope 83 is slidably installed on the side of the housing 1. The pulling end of the connecting rope 82 passes through the side of the housing 1 and is fixedly connected to the pull rope 83. A pull plate is fixedly installed on the pulling end of the pull rope 83. A guide wheel 84 corresponding to the pull rope 83 is rotatably installed on the side of the housing 1. The guide wheel 84 is located at the top corner of the housing 1.

[0023] The implementation principle of this embodiment is as follows: When a person accidentally touches the protective net 3, and their finger passes through it and touches its surface, the net 3 will experience a certain pushing force from the finger. This force will directly cause the mounting plate 52 connected to the protective net 3 to slide smoothly along the guide groove 51. At the same time, the connecting plate 75 on the mounting plate 52 will slide synchronously along the guide opening 55. The sliding of the connecting plate 75 will cause the drive rack 76 connected to it to move, which in turn will drive the drive gear 73 that is engaged with it to rotate. Since the drive gear 73 is fixedly mounted on the shaft 71, the rotation of the drive gear 73 will synchronously drive the shaft 71 and the transmission on the shaft 71. When gear 72 rotates together, the transmission gear 72 will drive the connecting plate 77 to move through the transmission rack 78 meshing with it. The connecting plate 77 will then drive the mounting plate 54 to slide along the guide groove 53 in the same direction as the protective net 3. Under the cooperation of the preset gear ratio of the drive gear 73 and the transmission gear 72, the sliding distance of the mounting plate 54 and the connected extermination net 4 will be greater than the sliding distance of the protective net 3. This will enable the extermination net 4 to quickly move away from the protective net 3, effectively reducing the risk of electric shock caused by accidental contact of the extermination net 4 with the fingers, and playing a good safety protection role. In daily use, when it is necessary to clean the dead mosquitoes attached to the killing net 4, the operator can pull the pull plate at the end of the pull rope 83. The pull rope 83 drives the connecting rope 82, which in turn drives the reel 81 to rotate. The rotation of the reel 81 drives the shaft 71. When the shaft 71 is driven to rotate, it will drive the connecting plate 77, the mounting plate 54, and the killing net 4 to slide through the cooperation of the transmission gear 72 and the transmission rack 78. When the operator releases the pull plate, the shaft 71 will rotate in the opposite direction under the elastic reset action of the torsion spring 74, thereby driving the killing net 4 to return to its initial position. The operator only needs to repeat the above operation steps of pulling and releasing the pull plate to realize the reciprocating vibration of the killing net 4. The force generated by the vibration shakes off the dead mosquitoes attached to the killing net 4, thereby achieving the cleaning effect of the killing net 4 and ensuring the normal use of the killing net 4.

[0024] Example 3: Based on Example 1, this example discloses a mosquito-trapping device for insect control, such as... Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, the protective component 9 includes two connecting shells 91 symmetrically fixedly installed at the outer opening of the outer shell 1. Both inner walls of the outer shell 1 are provided with connecting grooves 92 that communicate with the connecting shells 91. Several rotating rods 95 arranged in a linear array are rotatably installed on the inner wall of the connecting grooves 92. Protective plates 96 are fixedly installed on the outer walls of the rotating rods 95. The width of the protective plates 96 is the same as the vertical gap of the protective net 3. The protective plates 96 are initially set horizontally. A transmission structure is provided on several rotating rods 95. The transmission structure includes several transmission discs 93 fixedly fitted on the outer walls of the ends of several rotating rods 95. The several transmission discs 93 are connected by transmission bars 94. A torsion spring 99 is fitted on the outer wall of the top rotating rod 95 away from the transmission disc 93. The two ends of the torsion spring 99 are fixedly connected to the rotating rod 95 and the inner wall of the connecting groove 92, respectively. A slot 97 is provided on the outer wall of the rotating rod 95 away from the torsion spring 99. A card plate 98 that engages with the slot 97 is fixedly installed at the end of the protective net 3.

[0025] The implementation principle of this embodiment is as follows: When accidental contact occurs, and the protective net 3 is pushed by the finger of the person who accidentally touched it, the locking plate 98 at the end of the protective net 3 will move synchronously with the movement of the protective net 3, and then separate from the locking groove 97 at the end of the rotating rod 95. When the device is in the initial state, the protective plate 96 on the rotating rod 95 remains horizontal and will not affect the normal sliding and use of the protective net 3. When the locking plate 98 is completely separated from the locking groove 97, the limiting effect on the rotating rod 95 is completely released. At this time, under the elastic force of the torsion spring 99, the rotating rod 95 will rotate around its own axis. At the same time, the rotating rod 95 will drive several rotating rods 95 and corresponding protective plates 96 on the device to rotate synchronously through the cooperation of the transmission disc 93 and the transmission bar 94 at the end. This will cause the protective plate 96 to rotate to the position of contacting the back of the person who accidentally touched it, thereby providing a timely reminder to the person who accidentally touched it and reminding them to stop the accidental contact. Meanwhile, when the entire device is in a special situation where it is not needed, such as winter, the staff can manually push the protective net 3 to close the protective plate 96. When all the protective plates 96 are closed and in a vertical position, they can cover the inside of the outer shell 1 of the device, effectively preventing external dust and other debris from entering the device and avoiding dust from adhering to the killing net 4 and UVLED lamp 2 and affecting their normal use. In addition, during the process of cleaning up the mosquito carcasses on the killing net 4, the protective net 3 will move synchronously with the sliding of the killing net 4. During this process, the protective plate 96 will automatically release its limit and rotate. After the killing net 4 is cleaned, the user only needs to manually reset the protective plate 96 to its initial horizontal state, so that the locking plate 98 at the end of the protective net 3 can be re-locked into the locking groove 97 at the end of the rotating rod 95. After the limit is fixed, the device can continue to be used normally.

[0026] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
