Abstract
Description
Technical Field
[0001] This utility model relates to the field of insect trap technology, and more specifically, to a combined insect trap. Background Technology
[0002] In the existing field of insect control, combined insect traps are widely used as a common pest control device in agriculture, gardens, and home environments.
[0003] However, existing insect traps suffer from a series of technical problems that urgently need to be solved. Existing combined insect traps frequently experience insect escape after capture. This is mainly due to structural design flaws, such as poor sealing at the connection between the observation window and the trap body, or gaps that easily form during operation, allowing captured insects to escape. Especially when the observation window is opened for inspection, a large number of insects often escape, significantly reducing capture efficiency and increasing the risk of environmental pollution.
[0004] Meanwhile, cleaning insects from the sealed traps is extremely inconvenient. Traditional traps often use fixed or difficult-to-remove sealed structures, requiring the entire trap to be opened for cleaning. This is not only cumbersome but also prone to secondary contamination and insect escape. Furthermore, cleaning often requires the use of multiple tools, increasing the barrier to entry and maintenance costs. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, this utility model provides a combined insect trap with the following advantages:
[0018] This invention features an attraction and capture mechanism that forms a highly efficient capture system through a constricted bucket, an electric grid, and symmetrically installed insect-attracting lamps. The insect-attracting lamps utilize the phototaxis of insects to attract target insects, while the electric grid shocks insects flying towards the light source, rendering them immobile. The funnel-shaped design of the constricted bucket makes it easy for insects to enter but difficult for them to fly out. The observation windows on both sides of the trap facilitate real-time monitoring of the capture situation, and the sealing fan design can both close the observation windows in time to prevent insects from escaping and blow insects around the windows back into the trap, greatly improving capture efficiency and system airtightness.
[0019] This utility model features an installation locking mechanism. Through the ingenious cooperation of the locking tube, locking rod, and rotating blocks, the installation locking mechanism enables the rapid connection and separation of the blocking fan and the trapping box. The locking groove on the side wall of the locking rod forms a mechanical lock with the multiple sets of rotating blocks at the bottom of the inner rotating ring. Under the dual guidance of the top guide groove and the bottom guide groove, the movement of the rotating blocks is ensured to be smooth and accurate. The linkage connection between the outer rotating sleeve and the inner rotating ring makes the operation simple and intuitive, greatly improving the convenience and reliability of the installation and disassembly of the blocking fan, and solving the problem of inconvenient cleaning of traditional traps.
[0020] This utility model is equipped with a snap-fit auxiliary mechanism. The snap-fit auxiliary mechanism provides a secondary locking guarantee for the installation of the snap-fit mechanism through the coordinated work of the top ring, the directional ring, and the spring support spring. The threaded ring pushes the directional ring through the thrust bearing, so that the spring support spring on the directional ring extends into the spring support groove at the bottom of the top ring step by step to form an elastic lock. This effectively prevents the outer rotating sleeve from loosening due to vibration or collision during use, greatly enhances the structural stability and sealing reliability of the trap, ensures that insects will not escape, and at the same time ensures the safety and convenience of the cleaning operation.

[0030] Please see Figures 1-5 A combined insect trap includes a trap box 1, an attraction and capture mechanism, a mounting and locking mechanism, and a locking auxiliary mechanism. The attraction and capture mechanism includes a constricting hopper 2 and an electric grid 3. The constricting hopper 2 is installed at the top of the trap box 1, and the electric grid 3 is installed on the constricting hopper 2. The constricting hopper 2 connects to the interior of the trap box 1. Insect-attracting lamps 4 are symmetrically installed on the end face of the constricting hopper 2. Observation windows 5 are symmetrically installed on both sides of the trap box 1. A sealing fan 6 is detachably installed at the outer end of the observation window 5. The mounting and locking mechanism includes a locking tube 7 and a locking auxiliary mechanism. The snap-fit rod 8 has a snap-fit groove 9 on its side wall. The inner rotating ring 10 is rotatably installed on the inner wall of the snap-fit tube 7. The bottom end of the inner rotating ring 10 is rotatably installed with a limiting insert block 11. Multiple sets of insert blocks 11 are provided. The inner wall of the snap-fit tube 7 is fixedly installed with an inner retaining ring 12. The bottom end of the insert block 11 is slidably connected with the inner retaining ring 12. The outer rotating sleeve 13 is installed on the outer wall of the snap-fit tube 7. The outer rotating sleeve 13 is linked to the inner rotating ring 10. The insert block 11 can extend into or away from the snap-fit groove 9.
[0031] In this embodiment, the attraction and capture mechanism attracts and captures insects through the coordinated operation of the constricting hopper 2, the electric grid 3, and the insect-attracting lamp 4. During operation, the insect-attracting lamp 4, installed on the end face of the constricting hopper 2, emits light to attract surrounding insects. After being attracted by the light source, the insects fly towards the constricting hopper 2. When they pass through the electric grid 3 above the constricting hopper 2, they are electrocuted and killed. Then, they slide down the slope of the constricting hopper 2 into the trap box 1. The observation windows 5 on both sides of the trap box 1 allow the user to observe the capture situation in real time, while the sealing fan 6 can close the observation windows 5 when necessary to prevent insects from escaping. At the same time, it can also trap insects that remain around the observation windows 5. The air is re-blown into the box, and the snap-fit mechanism is installed to achieve quick connection and separation between the blocking fan 6 and the trap box 1 through the snap-fit tube 7 and snap-fit rod 8. In use, the snap-fit rod 8 connected to one corner of the blocking fan 6 is inserted into the snap-fit tube 7 fixed to one end face of the trap box 1. The inner rotating ring 10 on the inner wall of the snap-fit tube 7 rotates in conjunction with the outer rotating sleeve 13 on the outer wall, which drives the multiple sets of rotating insert blocks 11 at the bottom of the inner rotating ring 10 to rotate. Under the dual guidance of the top guide groove 23 and the bottom guide groove 24, the rotating insert blocks 11 accurately extend into the snap-fit groove 9 on the side wall of the snap-fit rod 8 to form a mechanical lock, so that the blocking fan 6 is firmly installed on the trap box 1.
[0032] The snap-fit auxiliary mechanism includes a top ring 14 and a directional ring 15. The top ring 14 is installed at the bottom end of the outer rotating sleeve 13, and the directional ring 15 is slidably installed on the outer wall of the snap-fit tube 7. A spring support spring 16 is installed on the directional ring 15. A spring support groove 17 is opened at the bottom end of the top ring 14. The spring support spring 16 extends into the spring support groove 17 in stages to make the outer rotating sleeve 13 rotate stably. A threaded ring 18 is threadedly connected to the outer wall of the snap-fit tube 7. A thrust bearing 19 is installed between the threaded ring 18 and the directional ring 15. The threaded ring 18 pushes the directional ring 15 to move, so that the spring support spring 16 is fixedly extended into the spring support groove 17, and the outer rotating sleeve 13 is fixed on the outer wall of the snap-fit tube 7.
[0033] In this embodiment, the snap-fit auxiliary mechanism provides an auxiliary locking function for installing the snap-fit mechanism through the cooperation of the top ring 14, the directional ring 15, and the spring support 16. After the sealing fan 6 is initially locked to the snap-fit tube 7 by the snap-fit rod 8, the operator rotates the threaded ring 18 on the outer wall of the snap-fit tube 7. The threaded ring 18 pushes the directional ring 15 to slide towards the top ring 14 through the thrust bearing 19. Under the action of the thrust, the spring support 16 on the directional ring 15 extends into the spring support groove 17 at the bottom of the top ring 14 step by step to form an elastic lock, so that the outer rotating sleeve 13 is fixed on the outer wall of the snap-fit tube 7, thereby stabilizing the position of the inner rotating ring 10 and the rotating insert 11, and preventing the lock from being released due to vibration or collision during use.
[0034] Please see Figures 1-5 As a supplementary embodiment of a combined insect trap consisting of an attraction and capture mechanism, a mounting and locking mechanism, and a locking auxiliary mechanism: A guide sleeve 20 is installed on the outer wall of the trapping box 1. A guide rod 21 is installed at one end of the sealing fan 6, and the guide rod 21 extends into the guide sleeve 20 in a directional manner. Multiple sets of sealing fans 6 are provided, and the sealing fans 6 blow insects around the observation window 5 back into the box. A connecting plate 22 is installed at the top end of one end of the locking tube 7, and the connecting plate 22 is fixedly installed on one end face of the trapping box 1. One end of the locking rod 8 is connected to one corner of the sealing fan 6, and the other end of the locking rod 8 extends into the locking tube 7 to engage. A top guide groove 23 is provided on the inner rotating ring 10, and the top end of the rotating block 11 is slidably pushed in conjunction with the top guide groove 23. A bottom guide groove 24 is provided on the inner fixed ring 12, and the bottom end of the rotating block 11 is slidably guided in conjunction with the bottom guide groove 24.
[0035] More specifically, place the trapping box 1 in the target area, ensuring stability, connect the power supply, and turn on the insect-attracting lamp 4 to create an effective light source bait. The insect-attracting lamp 4 attracts surrounding insects. When the insects fly towards the light source, they are stunned by the electric grid 3 and slide into the trapping box 1 through the constricting hopper 2. The capture situation is monitored in real time through the observation window 5. When it is necessary to clean the observation window 5 or prevent insects from escaping, the sealing fan 6 can be removed. Align the locking rod 8 at one corner of the sealing fan 6 with the locking tube 7 and insert it. Rotate the outer rotating sleeve 13 so that the inner rotating ring 10 drives the rotating insert block 11 to extend into the locking groove 9 of the locking rod 8, achieving initial capture. Lock the threaded ring 18, push the directional ring 15, and let the spring support spring 16 extend into the spring support groove 17 of the top ring 14 to achieve secondary locking. After the sealing fan 6 is completely fixed, it can be used to close the observation window 5 or blow insects around the window back into the box. When it is necessary to clean the trap box 1, first rotate the threaded ring 18 in the opposite direction to release the locking of the spring support spring 16 to the top ring 14, and then rotate the outer rotating sleeve 13 in the opposite direction to make the rotating insert block 11 exit the slot 9, release the lock on the locking rod 8, remove the sealing fan 6, open the observation window 5, clean the captured insects, and after cleaning, reinstall the sealing fan 6 in the reverse order.
[0036] In summary, when the entire device is in use or running: When the attraction and capture mechanism is in operation, it works in concert with the constriction bucket 2, the electric grid 3, and the insect-attracting lamp 4 to attract and capture insects. During operation, the insect-attracting lamp 4 installed on the end face of the constriction bucket 2 emits light, attracting surrounding insects to approach. After being attracted by the light source, the insects fly towards the constriction bucket 2. When they pass through the electric grid 3 above the constriction bucket 2, they are shocked or killed by electric shock. Then they slide down the slope of the constriction bucket 2 into the trap box 1. The observation windows 5 on both sides of the trap box 1 allow the user to observe the capture situation in real time, while the sealing fan 6 can close the observation windows 5 when necessary to prevent insects from escaping. At the same time, it can also blow the insects that are staying around the observation windows 5 back into the box.
[0037] When the snap-fit mechanism is installed, it enables quick connection and separation of the blocking fan 6 and the trap box 1 via the snap-fit tube 7 and snap-fit rod 8. In use, the snap-fit rod 8 connected to one corner of the blocking fan 6 is inserted into the snap-fit tube 7 fixed to one end face of the trap box 1. The inner rotating ring 10 on the inner wall of the snap-fit tube 7 rotates in conjunction with the outer rotating sleeve 13 on the outer wall, causing multiple sets of rotating insert blocks 11 at the bottom of the inner rotating ring 10 to rotate. Under the dual guidance of the top guide groove 23 and the bottom guide groove 24, the rotating insert blocks 11 accurately extend into the snap-fit groove 9 on the side wall of the snap-fit rod 8, forming a mechanical lock, so that the blocking fan 6 is firmly installed on the trap box 1.
[0038] When the locking auxiliary mechanism is required to operate, the locking auxiliary mechanism provides an auxiliary locking function for the installation of the locking mechanism through the cooperation of the top ring 14, the directional ring 15 and the spring support 16. After the sealing fan 6 is initially locked to the locking tube 7 by the locking rod 8, the operator rotates the threaded ring 18 on the outer wall of the locking tube 7. The threaded ring 18 pushes the directional ring 15 to slide towards the top ring 14 through the thrust bearing 19. Under the action of the thrust, the spring support 16 on the directional ring 15 extends into the spring support groove 17 at the bottom of the top ring 14 step by step to form an elastic lock, so that the outer rotating sleeve 13 is fixed on the outer wall of the locking tube 7, thereby stabilizing the position of the inner rotating ring 10 and the rotating insert 11, and preventing the lock from being released due to vibration or collision during use.
[0039] Place the trap box 1 in the target area, ensuring stability. Connect the power supply and turn on the insect-attracting lamp 4 to create an effective light source bait. The lamp 4 attracts surrounding insects, and when the insects fly towards the light source, they are stunned by the electric grid 3. The insects then slide into the trap box 1 through the constricting hopper 2. Monitor the capture situation in real time through the observation window 5. When it is necessary to clean the observation window 5 or prevent insects from escaping, remove the sealing fan 6. Align the locking rod 8 at one corner of the sealing fan 6 with the locking tube 7 and insert it. Rotate the outer rotating sleeve 13 so that the inner rotating ring 10 drives the rotating insert block 11 to extend into the locking groove 9 of the locking rod 8, achieving initial locking. Rotate the threaded ring 18 to push the directional ring 15, so that the spring support spring 16 extends into the spring support groove 17 of the top ring 14 to achieve secondary locking. After the sealing fan 6 is completely fixed, it can be used to close the observation window 5 or blow insects around the window back into the box. When it is necessary to clean the trap box 1, first rotate the threaded ring 18 in the opposite direction to release the lock of the spring support spring 16 on the top ring 14, and then rotate the outer rotating sleeve 13 in the opposite direction to make the rotating insert block 11 exit the slot 9, release the lock on the locking rod 8, remove the sealing fan 6, open the observation window 5, clean the captured insects, and after cleaning, reinstall the sealing fan 6 in the reverse order.
