[0002] For example, Chinese patent CN104896546A discloses a range hood that includes a housing, an air supply module, and a semiconductor cooling chip. The first heat exchange end of the semiconductor cooling chip regulates the temperature of the airflow blown by the air supply module. In particular, the range hood also includes a heat pipe disposed in the housing. The first end of the heat pipe is in thermal contact with the second heat exchange end of the semiconductor cooling chip, and the second end is in thermal contact with the inner wall of the housing, so as to conduct the heat generated by the second heat exchange end of the semiconductor cooling chip to the inner wall of the housing.

[0003] However, the above solution has the following shortcomings: The above patent changes the air temperature of the airflow blown to the user by the conductor cooling plate, which improves the user's comfort without affecting the normal operation of the stove. However, there are often some harmful insects such as mosquitoes and flies in the kitchen. Some insects will fall onto the surface of the food when people are cooking, and some insects will carry bacteria on the surface of vegetables or fruits after falling onto the surface of the food. Therefore, we have launched a range hood with laser insect killing function. Summary of the Invention

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-6 The present invention provides a technical solution: Example

[0017] A range hood with laser insect-killing function includes a smoke extraction base plate 1. An air inlet screen is located at the lower end of the smoke extraction base plate 1 to prevent impurities from the external environment from entering the smoke extraction base plate 1. An exhaust pipe 2 is fixedly connected to the upper end of the smoke extraction base plate 1, and an exhaust fan is installed inside the exhaust pipe 2. The exhaust fan draws fumes through the smoke extraction base plate 1 into the exhaust pipe 2. A storage cavity 3 is fixedly connected to the lower end of the smoke extraction base plate 1. A support plate 4 is movably connected to the storage cavity 3. A first U-shaped plate 11 is fixedly connected to the lower end of the support plate 4, and the lower end of the first U-shaped plate 11 is movably connected to the upper end of a second U-shaped plate 8. The upper end of the second U-shaped plate 8 is fixedly connected to the upper end of the connecting seat 14. A guide groove 21 is provided in the upper end of the connecting seat 14. A sealing mechanism is provided in the guide groove 21. The sealing mechanism meshes with the limiting mechanism. Under the gravity of the connecting seat 14, the second U-shaped plate 8 moves downward from the storage cavity 3. The movement of the connecting seat 14 drives the first U-shaped plate 11 to move. The limiting mechanism is located inside the connecting seat 14. When the first U-shaped plate 11 and the second U-shaped plate 8 are retracted into the receiving cavity 3, the limiting mechanism will contact and move with the smoking base plate 1. The movement of the limiting mechanism drives the sealing mechanism to move, thus removing the obstruction to the guide channel 21. The lower end of the support plate 4 is fixedly connected to a vision camera 22 and a laser emitter 23. The specific model of the vision camera 22 is acA2500-14gc produced by Shenzhen Jingqing Optoelectronics Co., Ltd., and the specific model of the laser emitter 23 is LT-53080FP-Y330A1 produced by Guangzhou Junzhi Technology Co., Ltd. Based on the disclosed models of the above two electrical components, combined with the use of the product by those skilled in the art, and combined with the operation of conventional technology, the image signal captured by the vision camera 22 can be processed by existing simple image recognition algorithms, and the laser emitter 23 can be controlled to perform laser disinfection after data processing.

[0018] The lower end of the connecting seat 14 is attached to a collection mechanism. The target is converted into an image signal by the image camera 22. The image processing system analyzes the features and then automatically compares and identifies the position of the target insect. The insect is irradiated with a laser beam. The laser penetrates the insect's body and the insect is collected in the guide channel 21 after being disinfected. Two traction ropes 16 are fixedly connected to the upper end of the connecting seat 14. The upper end of the traction ropes 16 passes through the smoke extraction base plate 1 and is connected to the winding mechanism. The winding mechanism is fixedly installed on the upper end of the smoke extraction base plate 1. An insect-attracting light strip 5 is fixedly installed on the inner side of the second U-shaped plate 8. The insect-attracting light strip 5 is an ultraviolet light strip. Example

[0019] Based on embodiment 1, in order to prevent the first U-shaped plate 11 and the second U-shaped plate 8 from detaching from the storage cavity 3, T-shaped blocks 24 are fixedly connected to both ends of the support plate 4. The T-shaped blocks 24 slide in the T-shaped groove 28, which is opened in the storage cavity 3. The lower end of the first U-shaped plate 11 is provided with an outwardly extending protrusion. The lower end of the first U-shaped plate 11 slides in the T-shaped connecting cavity 26, which is opened in the upper end of the second U-shaped plate 8. Under the gravity of the connecting seat 14, the second U-shaped plate 8 moves downward from the storage cavity 3. The movement of the connecting seat 14 drives the first U-shaped plate 11 to move. The T-shaped blocks 24 connected at both ends of the support plate 4 will move along the T-shaped groove 28. When the T-shaped blocks 24 move to the bottom of the T-shaped groove 28, the movement stops. The sealing mechanism includes two sealing plates 7, which are disposed within the guide groove 21. Both ends of the sealing plates 7 are fixedly connected to external threaded rods 27, which are movably connected to the connecting seat 14. The end of the external threaded rod 27 away from the sealing plate 7 extends into the guide cavity 13 and engages with a limiting mechanism. The limiting mechanism includes a shaped toothed plate 12 with several toothed grooves on both sides. The external threaded rod 27 is disposed on both sides of the shaped toothed plate 12 and engages with the toothed grooves. The shaped toothed plate 12 slides within the guide cavity 13, which is located within the connecting seat 14 and communicates with the outside. One end of the shaped toothed plate 12 extends into the external environment through the guide cavity 13. A limiting hole 10 is provided on the upper side of the shaped toothed plate 12, and the lower end of the guide cavity 13 is fixed. A support spring 15 is connected, and the upper end of the support spring 15 is fixedly connected to the shaped toothed plate 12. A limiting hole 10 is opened in the lower end of the smoking base plate 1. A telescopic cylinder 9 is fixedly installed in the limiting hole 10. An insertion hole 25 is opened on the outer side of the shaped toothed plate 12. As the connecting seat 14 moves upward, the first U-shaped plate 11 will be driven to move. When the upper end of the shaped toothed plate 12 is inserted into the limiting hole 10, as the connecting seat 14 continues to move upward, the shaped toothed plate 12 will move downward along the guide cavity 13. At this time, the support spring 15 is compressed. At the same time, when the shaped toothed plate 12 moves downward, it will drive the external threaded rods 27 meshing on both sides to start rotating. The rotation of the external threaded rods 27 drives the sealing plate 7 to rotate. The rotation of the two sealing plates 7 cancels the obstruction of the guide groove 21. The collection mechanism includes a mounting ring 20, with several magnets 29 fixedly connected to the upper end of the mounting ring 20. A collection bag 6 is fitted inside the mounting ring 20. The mounting ring 20 is attracted and installed at the lower end of the connecting seat 14 by the magnets 29. At the same time, the upper side of the collection bag 6 is clamped between the connecting seat 14 and the mounting ring 20. The two sealing plates 7 rotate to remove the obstruction to the guide groove 21. At this time, insects will enter the collection bag 6 and be collected. The collection bag 6 containing insects can be removed by removing the mounting ring 20 and discarded. The upper side of the collection bag 6 can be reattached to the upper end of the mounting ring 20 and attracted to the lower end of the connecting seat 14 by the magnets 29. The winding mechanism includes a dual-axis motor 17, which is fixedly installed inside a protective housing 18. The protective housing 18 is fixedly installed on the upper end of the smoke extraction base plate 1. The two output ends of the dual-axis motor 17 are respectively fixedly connected to winding wheels 19. A traction rope 16 is fixedly connected to the outside of the winding wheels 19. When the dual-axis motor 17 is started, it drives the two winding wheels 19 to rewind the traction rope 16. After the traction rope 16 is wound up, it drives the connecting seat 14 to move upward. The movement of the connecting seat 14 drives the second U-shaped plate 8 to move.

[0020] Working principle: During use, the exhaust fan draws the fumes through the exhaust base plate 1 into the exhaust pipe 2. After exhaust is complete, the dual-shaft motor 17 and the telescopic cylinder 9 are turned on. After the telescopic cylinder 9 starts, its output end moves out of the socket 25. After the dual-shaft motor 17 starts, it drives the two winding wheels 19 to start rotating. The rotation of the winding wheels 19 cancels the winding of the traction rope 16. At this time, under the gravity of the connecting seat 14, the second U-shaped plate 8 moves downward from the storage cavity 3. The movement of the connecting seat 14 drives the first U-shaped plate 11 to move. The T-shaped blocks 24 connected at both ends of the support plate 4 will move along the T-shaped... The groove 28 moves, and when the T-shaped block 24 moves to the bottom of the T-shaped groove 28, the movement stops. The insect-attracting light strip 5 is turned on to attract insects. When the insect moves to the inside of the first U-shaped plate 11 and the second U-shaped plate 8, the visual camera 22 uses an image camera to convert the target into an image signal. The image processing system analyzes the features and then automatically compares and identifies the position of the target insect. The laser emitter 23 is controlled to use a laser beam to irradiate the insect. The laser penetrates the insect's body to disinfect the insect. The disinfected insect falls into the guide channel 21 for storage. When the range hood needs to be reused, the dual-shaft motor 17 starts, driving the two winding wheels 19 to rewind the traction rope 16. After being wound up, the traction rope 16 moves the connecting seat 14 upwards. The movement of the connecting seat 14 moves the second U-shaped plate 8. When the bottom of the T-shaped connecting cavity 26 within the second U-shaped plate 8 contacts the lower end of the first U-shaped plate 11, the first U-shaped plate 11 moves along with the upward movement of the connecting seat 14. When the upper end of the irregularly shaped toothed plate 12 is inserted into the limiting hole 10, this... As the connecting seat 14 continues to move upward, the shaped toothed plate 12 will move downward along the guide cavity 13. At this time, the support spring 15 is compressed. Simultaneously, when the shaped toothed plate 12 moves downward, it will drive the external threaded rods 27 meshing on both sides to start rotating. The rotation of the external threaded rods 27 will drive the sealing plate 7 to rotate. The rotation of the two sealing plates 7 will remove the obstruction to the guide groove 21. At this time, the insect will enter the collection bag 6 and be collected. The output end of the control telescopic cylinder 9 will be reconnected to the insertion hole 25 to limit the shaped toothed plate 12. Remove the collection bag 6 containing insects by removing the mounting ring 20 and discard it. Then, reattach the upper side of the collection bag 6 to the upper end of the mounting ring 20 and attach it to the lower end of the connector 14 using the magnet 29.
