[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, a ventilation device for cooling a greenhouse includes a mounting shell 1, a threaded hole 14, a mosquito-killing lamp 3, a limiting part 2, a snap-fit ​​rod 21, a rotating shaft 24, and a torsion spring 25. The mounting shell 1 is installed at the ventilation point of the greenhouse, and the mounting shell 1 is an open design for placing the threaded hole 14.

[0026] To attract mosquitoes around the threaded hole 14, the mosquito killer lamp 3 is detachably connected to the mounting shell 1. It should be noted that the mosquito killer lamp 3 attracts mosquitoes primarily by emitting ultraviolet light with a wavelength of approximately 365nm, combined with carbon dioxide to simulate a mosquito killer lamp. Secondly, it uses a heated incandescent lamp to emit ultraviolet light with a wavelength close to 365nm, which is the phototactic sensitive area for most insects. Photocatalytic technology is used to simulate the carbon dioxide exhaled by humans to enhance the trapping effect. Some models further attract similar insects through pheromones released by live mosquitoes, forming a chain reaction. The above are publicly available technologies.

[0027] In order to achieve the detachable connection of the mosquito killer lamp 3, the limiting part 2 is rotatably connected to the mounting shell 1, and part of the limiting part 2 is inserted into the mosquito killer lamp 3 to limit the position of the mosquito killer lamp 3.

[0028] The limiting part 2 includes a snap-fit ​​rod 21, a limiting plate 22, a housing 23, a torsion spring 25, and a rotating shaft 24. It should be noted that the snap-fit ​​rod 21 is mounted on the mounting housing 1 and has a hook-shaped design. The housing 23 is fitted onto the bottom of the snap-fit ​​rod 21. The torsion spring 25 is connected and installed inside the housing 23. The bottom of the housing 23 is connected to the rotating shaft 24, which is connected to the bottom of the housing 23 and the top of the mounting housing 1. The torsion spring 25 is retracted inside the housing 23, and the top and bottom of the housing 23 can be detachably connected by hooking or bolts.

[0029] The torsion spring 25 is fully inserted into the housing 23. The top of the torsion spring 25 is connected to the bottom of the locking rod 21, and the bottom of the torsion spring 25 is connected to the interior of the housing 23. The end of the locking rod 21 away from the housing 23 is connected to the limiting plate 22. The limiting plate 22 and the locking rod 21 are welded together. In use, without external force, the torsion spring 25 will limit the locking rod 21 and the limiting plate 22 to a certain position. Figure 1 At the location shown.

[0030] The bottom of the mosquito killer lamp 3 is connected to a mounting base plate 31, which is bolted to the mosquito killer lamp 3. Mounting holes 32 are provided at the four corners inside the mounting base plate 31. The mounting holes 32 and the mounting base plate 31 are integrally molded.

[0031] Both the mounting hole 32 and the limiting plate 22 are circular. The mounting hole 32 and the limiting plate 22 are inserted into each other. When the torsion spring 25 is inserted into the mounting hole 32, the limiting plate 22 and the mounting hole 32 are coaxial.

[0032] The effect achieved by the entire embodiment is as follows: In use, first rotate the locking rod 21 to change its orientation, then place the mounting base plate 31 in the designated position. At this time, pull the locking rod 21 upward. Since the locking rod 21 and the housing 23 are in an inserted state, the locking rod 21 and the housing 23 can be stretched and extended. Then release the locking rod 21. At this time, the locking rod 21 will return to its original position under the action of the torsion spring 25. Figure 1 The positioning plate 22 and the mounting hole 32 are inserted into each other. At the same time, the locking rod 21 will retract into the sleeve 23 again, causing the limiting plate 22 and the mounting hole 32 to be inserted into each other. Both the limiting plate 22 and the mounting hole 32 are as follows. Figure 3 The setup shown has four units. After the four units are connected, the position of the mosquito killer lamp 3 will be limited. If the mosquito killer lamp 3 malfunctions, rotate and pull the locking rod 21 again to separate the locking rod 21 from the mounting hole 32, thus separating the mosquito killer lamp 3. In actual use, the mosquito killer lamp 3 attracts mosquitoes mainly by emitting ultraviolet light with a wavelength of about 365nm, combined with carbon dioxide to simulate a mosquito killer lamp. Secondly, the incandescent lamp that generates heat emits ultraviolet light with a wavelength close to 365nm, which is the phototactic sensitive area of ​​most insects. Photocatalytic technology is used to simulate the carbon dioxide exhaled by humans to enhance the trapping effect. Some models further attract similar insects by using pheromones released by live mosquitoes, forming a chain reaction to kill mosquitoes and reduce the probability of mosquitoes entering the threaded hole 14.

[0033] Example 2

[0034] like Figure 1-5 As shown, a ventilation device for cooling a greenhouse includes a fan 11 inside a housing 1. The fan 11 is connected to the inner wall of the housing 1. The fan 11 operates on the principle that air is driven by a prime mover such as a motor to rotate an impeller, converting the input mechanical energy into the kinetic energy, velocity energy, or pressure energy, or potential energy of the gas. This process follows the law of conservation of energy. After the gas is accelerated in the impeller, it is decelerated by components such as a diffuser, and the kinetic energy is further converted into pressure energy, thereby achieving the cooling treatment of the greenhouse. This is the disclosed technology.

[0035] The inner wall of the mounting housing 1 is provided with a threaded vent 12, which penetrates the side of the mounting housing 1. The threaded vent 12 is used for ventilation of the fan 11 to reduce overheating damage to the fan 11 during use.

[0036] The end face of the mounting shell 1 away from the threaded vent 12 is connected to a mounting frame 13. Threaded holes 14 are provided at the four corners of the mounting frame 13. The mounting frame 13 is welded to the open side of the mounting shell 1. The threaded holes 14 and the mounting frame 13 are integrally molded. The threaded holes 14 are used for mounting the mounting shell 1 and the greenhouse.

[0037] The effect achieved by the entire embodiment 2 is that, in use, the principle of the fan 11 is that the wind drives the impeller to rotate through a prime mover such as a motor, converting the input mechanical energy into the kinetic energy, velocity energy, or pressure energy and potential energy of the gas. This process follows the law of conservation of energy. After the gas is accelerated in the impeller, it is decelerated through components such as a diffuser, and the kinetic energy is further converted into pressure energy, thereby achieving the cooling treatment of the greenhouse. The threaded vent 12 is used for ventilation of the fan 11 to reduce the risk of overheating damage to the fan 11 during use. The mounting frame 13 is welded to the open side of the mounting shell 1. The threaded hole 14 and the mounting frame 13 are integrally molded. The threaded hole 14 is used for installation of the mounting shell 1 and the greenhouse.

[0038] Working principle: When using this greenhouse cooling and ventilation equipment with an external power supply, first rotate the locking rod 21 to change its orientation. Then place the mounting base plate 31 in the designated position. At this time, pull the locking rod 21 upward. Since the locking rod 21 and the housing 23 are in an inserted state, the locking rod 21 and the housing 23 can be stretched and extended. Then release the locking rod 21. At this time, the locking rod 21 will return to its original position under the action of the torsion spring 25. Figure 1 The positioning plate 22 and the mounting hole 32 are inserted into each other. At the same time, the locking rod 21 will retract into the sleeve 23 again, causing the limiting plate 22 and the mounting hole 32 to be inserted into each other. Both the limiting plate 22 and the mounting hole 32 are as follows. Figure 3 The setup shown has four units. After the four units are connected, the position of the mosquito killer lamp 3 will be limited. If the mosquito killer lamp 3 malfunctions, rotate and pull the locking rod 21 again to separate the locking rod 21 from the mounting hole 32, thus separating the mosquito killer lamp 3. In actual use, the mosquito killer lamp 3 attracts mosquitoes mainly by emitting ultraviolet light with a wavelength of about 365nm, combined with carbon dioxide to simulate a mosquito killer lamp. Secondly, the incandescent lamp that generates heat emits ultraviolet light with a wavelength close to 365nm, which is the phototactic sensitive area of ​​most insects. Photocatalytic technology is used to simulate the carbon dioxide exhaled by humans to enhance the trapping effect. Some models further attract similar insects through the pheromones released by live mosquitoes, forming a chain reaction to kill mosquitoes and reduce the probability of mosquitoes entering the threaded hole 14.

[0039] Finally, the principle of the fan 11 is that the wind drives the impeller to rotate through a prime mover such as a motor, converting the input mechanical energy into the kinetic energy, velocity energy, or pressure energy and potential energy of the gas. This process follows the law of conservation of energy. After the gas is accelerated in the impeller, it is decelerated through components such as a diffuser, and the kinetic energy is further converted into pressure energy, thereby achieving the cooling treatment of the greenhouse. The threaded vent 12 is used for ventilation of the fan 11 to reduce the risk of overheating damage during use. The mounting frame 13 is welded to the open side of the mounting shell 1. The threaded hole 14 and the mounting frame 13 are integrally molded. The threaded hole 14 is installed with the mounting shell 1 and the greenhouse, thus completing the function of the ventilation equipment for cooling the greenhouse.
