Description

Technical Field

[0001] The utility model relates to the technical field of greenhouses, in particular to a ventilation and sterilization device for a greenhouse. Background Art

[0002] Greenhouses, also known as hothouses, are facilities used to cultivate plants, allowing light to pass through and retaining heat (or providing heating). They provide a greenhouse growth period and increase yields during seasons unsuitable for plant growth. They are often used for cultivating or raising seedlings of warmth-loving vegetables, flowers, trees, and other plants during low-temperature seasons. When growing vegetables in a greenhouse, ventilation systems are typically installed.

[0003] After searching, the applicant discovered that a Chinese patent disclosed "a greenhouse ventilation device" with the publication number "CN221203524U", which includes a greenhouse main body, a ventilation pipe and a rain cover provided on the outer wall of the greenhouse main body, a ventilation fan provided inside the ventilation pipe, a filter assembly for filtering the air provided inside the ventilation pipe, and a clamping assembly for clamping with the filter assembly provided on the top of the ventilation pipe. The utility model filters dust and impurities contained in the air through the provided filter assembly, filters and protects dust and insects through the provided filter core and insect-proof plate, and prevents dust and insects from entering the interior of the greenhouse main body and causing certain damage to the vegetables inside the greenhouse main body. The device is installed by inserting the provided mounting rail into the interior of the mounting slot, thereby facilitating the disassembly of the device, and the device is sealed by the provided sealing ring and fixing plate.

[0004] However, ventilation systems absorb large amounts of dust, impurities, and insects during operation. Some ventilation systems with filters can easily become clogged, affecting ventilation efficiency. Furthermore, cleaning these filters and ventilation ducts requires considerable time and effort. For example, in the summer, when greenhouses are infested with insects, ventilation system filters can easily become clogged with dead insects and dust, requiring frequent cleaning, which can lead to poor ventilation. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-5The greenhouse ventilation and sterilization device shown includes a greenhouse body 1 and a through door 2 provided on one side of the greenhouse body 1. A ventilation pipe 3 is fixedly connected to one side of the surface of the greenhouse body 1. An isolation structure 5 is slidably connected to one side of the surface of the ventilation pipe 3, which can be easily disassembled when the air is isolated for a long time, thereby facilitating the cleaning of accumulated dust. An exhaust pipe 6 is fixedly connected to the side of the surface of the greenhouse body 1 away from the ventilation pipe 3, and one side of the ventilation pipe 3 and the exhaust pipe 6 are both fixedly connected with a through pipe 4, and both sides of the inner wall of one of the through pipes 4 are fixedly connected with a sterilization heating lamp 7. The utility model uses the sterilization heating lamp 7 provided inside one of the through pipes 4 to generate heat energy, and uses the internal direction of the exhaust pipe 6 to generate heat energy. The fan 10 is used to transport heat energy to achieve a sterilization effect. During ventilation, the fan 10 with the opposite direction inside the ventilation pipe 3 is used to transport the internal air out, thereby producing a ventilation effect. When the isolation grid 504 is full of dust, just pull up the plug rod 506. While contacting the clamping effect, the elastic top plate 503 of the spring 502 will be used to push out the isolation grid 504, thereby starting the dust cleaning work, avoiding the shortcomings of most ventilation isolation grids 504 that are prone to dust accumulation and difficult to clean. The easy disassembly effect allows the isolation grid 504 to be quickly pulled out for cleaning, which will not affect the use effect of the greenhouse and enables the greenhouse to resume work quickly and effectively.

[0023] like Figure 2-4 As shown, the isolation structure 5 includes an extension groove 501, a spring 502, and a top plate 503. The extension groove 501 is opened on one side of the surface of the ventilation pipe 3, and multiple springs 502 are fixedly connected to one side of the inner wall of the extension groove 501. The top plate 503 is slidably connected to the opposite side of the inner wall of the extension groove 501. One side of the surface of the top plate 503 is respectively fixedly connected to one side of the surface of multiple springs 502. The isolation structure 5 also includes an isolation grid 504, a plug-in groove 505, and a plug-in rod 506. The isolation grid 504 is slidably connected to the inner wall of the extension groove 501, and the plug-in groove 505 is opened inside the isolation grid 504. The plug-in rod 506 is slidably connected to the inside of the ventilation pipe 3 and extends to the inside of the extension groove 501. The rod wall of the plug-in rod 506 extends to the inside of the plug-in groove 505 and is slidably connected to the inner wall of the plug-in groove 505.

[0024] like Figure 2 and Figure 5 As shown, mounting blocks 8 are fixedly connected to opposite sides of the inner walls of the ventilation duct 3 and the exhaust duct 6, micromotors 9 are fixedly connected to the inner walls of the two mounting blocks 8, and fans 10 are fixedly connected to the output ends of the two micromotors 9. The direction of the fan 10 inside the ventilation duct 3 is reverse, and the direction of the fan 10 inside the exhaust duct 6 is forward. By utilizing the forward and reverse effects, a ventilation effect can be generated on one side, while a sterilization air intake effect can be generated on the other side.

[0025] like Figure 3-4As shown, limiting grooves 11 are provided on both sides of the inner wall of the ventilation pipe 3, and the inner walls of the two limiting grooves 11 are slidably connected to limiting blocks 12. The two limiting blocks 12 are fixedly connected to both sides of the surface of the isolation grid 504, which can enable the isolation grid 504 to be plugged into the interior of the ventilation pipe 3 while standardizing the plug-in position.

[0026] Working principle of the utility model: when the utility model is used, the sterilization heating lamp 7 provided inside the through tube 4 is used to generate heat energy, and then the fan 10 with a positive direction inside the exhaust pipe 6 is used to work, so that the heat generated by the sterilization heating lamp 7 can be transported into the interior of the greenhouse body 1 to achieve a sterilization effect. However, when ventilating, the fan 10 with a reverse direction inside the ventilation pipe 3 is used to transport the internal air out, thereby producing a ventilation effect.

[0027] When the isolation grid 504 is filled with dust due to long-term ventilation, it is only necessary to pull up the plug rod 506 extending from the top surface of the ventilation pipe 3 so that the plug rod 506 is pulled out from the inside of the plug slot 505. When the clamping effect is released, the elastic potential energy generated by the previous squeezing of the spring 502 is used, and then the top plate 503 fixedly connected on one side is used to push out the isolation grid 504, so that the dust cleaning work can be carried out smoothly. When cleaning is completed, it is only necessary to insert the isolation grid 504 into the interior of the ventilation pipe 3 again, squeeze the spring 502, and then reset the plug rod 506 to the inside of the plug slot 505, finally forming a clamping effect.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
