[0002] In the currently prevalent greenhouse vegetable cultivation model, ventilation plays an indispensable role in ensuring effective air circulation and suitable temperature and humidity regulation within the greenhouse. However, it is worth noting that traditional ventilation methods exhibit several significant drawbacks in practical applications. The most prominent is that ventilation openings easily become the main entry point for pests into the greenhouse. Once pests enter the greenhouse through these pathways, they pose a serious threat to vegetable crops, leading to a series of chain reactions such as reduced yield and compromised quality. Furthermore, current ventilation opening designs are significantly inadequate in terms of pest control measures, often relying solely on physical shielding. This not only fails to achieve comprehensive pest containment but may also negatively impact ventilation efficiency to some extent. Utility Model Content

[0034] Inside the ventilation duct 2, a ventilation fan 13 is installed. The ventilation fan 13 adopts a high-efficiency and low-noise design, and its blades are made of a special material with good wear resistance and wind resistance. The ventilation fan 13 is fixed to the ventilation duct 2 with bolts to ensure its stable and reliable operation.

[0035] The base box 10 is located on the outer side of the middle position of the air exchange duct body 2. The base box 10 is made of waterproof and moisture-proof material, with sufficient internal space to accommodate the battery pack 12 and other related electronic equipment. It has good weather resistance and impact resistance.

[0036] The top cover 4 is positioned above the base box 10 to protect the internal equipment and prevent rainwater intrusion. The top cover 4 is made of a transparent material, such as high-strength acrylic glass, to ensure that it does not affect the light transmission of the photovoltaic panels. A sealing strip is provided around the top cover 4 to ensure a good seal at its connection with the base box 10.

[0037] The battery pack 12 is housed inside the base box 10. The battery pack 12 consists of multiple high-performance lithium batteries and provides a continuous and stable power supply to the ventilation fan 13. The battery pack 12 is connected to the photovoltaic panel 6 via a dedicated charging controller to ensure normal operation even in low-light conditions.

[0038] The photovoltaic panel 6, made of polycrystalline silicon, is installed on top of the top cover 4. The photovoltaic panel 6 is fixed to the top cover 4 by a bracket made of stainless steel, which offers good corrosion resistance and load-bearing capacity. The photovoltaic panel 6 is connected to the battery pack 12 via cables to ensure efficient power transmission.

[0039] The top cover 4 is fixedly connected to the ventilation duct 2 via the supporting beams 9 and the clamps 3. A ventilation opening 15 is provided between adjacent supporting beams 9, which is connected to the internal air cavity 5 of the top cover 4. An insect repellent box 7 is installed on the top of the air cavity 5 via a cantilever. Insect-proof net components 14 are installed on the inner side of the ventilation openings 15. Fixing blocks 11 for fixing the insect-proof net components 14 are provided on the supporting beams 9 on the outer side of the ventilation openings 15 and the bottom of the top cover 4.

[0040] One end of the ventilation duct 2 extends to the inside of the greenhouse frame 1, and the other end of the ventilation duct 2 extends to the inside of the top cover 4. The top of the ventilation duct 2 is located directly below the insect repellent box 7.

[0041] The inner wall of the ventilation duct 2 is uniformly provided with guide grooves 201. The outer side of the mounting plate of the ventilation fan 13 is provided with a limiting strip 1301 that matches the guide grooves 201. The ventilation fan 13 is installed at the bottom of the ventilation duct 2 through the mounting plate.

[0042] The insect repellent box 7 contains insect repellent medication, and the insect repellent box 7 includes a rectangular frame and a breathable mesh 8 set on the side wall of the rectangular frame.

[0043] The overall structure of the insect repellent box 7 includes a rectangular frame 1 and a breathable mesh 8 disposed on the side wall of the rectangular frame 1. The rectangular frame 1 is composed of four rectangular borders, forming a stable support structure. The material of the rectangular frame 1 is preferably plastic or metal to ensure its good durability and stability.

[0044] The breathable mesh 8 is installed on the four side walls of the rectangular frame 1. The mesh size of the breathable mesh 8 is moderate, which can ensure air circulation while preventing the insect repellent from escaping. The breathable mesh 8 is fixed to the side walls of the rectangular frame 1 by clips or adhesive, making installation simple and secure.

[0045] The insect repellent box 7 contains insect repellent medication. The medication can be in the form of solid granules, powder, or liquid, depending on the specific application requirements.

[0046] The insect repellent is placed at the bottom of the insect repellent box 7. A tray can be placed at the bottom, preferably made of plastic or metal, to prevent the insect repellent 2 from directly contacting the inner wall of the insect repellent box 7 and to extend the service life of the insect repellent box 7.

[0047] When using, place the insect repellent medication on the tray of the insect repellent box 7. The insect repellent medication is slowly released through the breathable mesh 8 to achieve the insect repellent effect.

[0048] Regular checks: Regularly check the consumption of deworming medication and replenish or replace it in a timely manner to ensure continuous deworming effect.

[0049] The insect net assembly 14 includes a rigid support frame 1401 and a fine net 1402. The fine net 1402 is evenly laid on the surface of the rigid support frame 1401 and is connected to the battery pack 12. The area of ​​the rigid support frame 1401 is smaller than the opening area of ​​the vent 15.

[0050] The rigid support frame 1401 is made of high-strength material to ensure that it is not easily deformed during use and provides stable support. The fine mesh 1402 is evenly laid on the surface of the rigid support frame 1401 to form a dense protective layer, effectively preventing insects from entering.

[0051] The rigid support frame 1401 is customized according to the actual application scenario, but its area is designed to be smaller than the opening area of ​​the vent 15, so as to ensure that the insect net assembly 14 can completely cover the vent without affecting the ventilation effect.

[0052] Fine mesh 1402 mesh size: Depending on the insect control requirements, the mesh diameter is usually between 0.5mm and 1mm, which can effectively block insects while ensuring good ventilation.

[0053] Laying method: The fine mesh 1402 is evenly laid on the surface of the rigid support frame 1401 through an elastic fixing device to ensure that the fine mesh is tightly attached to the support frame and is not easy to fall off.

[0054] The connection method between the fine mesh 1402 and the battery pack 12 is as follows:

[0055] Conductive fibers: Conductive fibers are embedded in the fine mesh 1402, and these fibers are evenly distributed across the entire mesh surface.

[0056] Connection port: A connection port is provided on one side of the rigid support frame 1401, which is connected to the positive and negative terminals of the battery pack 12 through wire pieces to form a closed circuit.

[0057] Circuit design: When the fine mesh 1402 is touched by an external force, the circuit closes, generating a weak current that repels insects.

[0058] Once the insect-proof netting component 14 is installed, its working principle is as follows:

[0059] 1. Physical barrier: Fine mesh 1402, with its high-density mesh structure, effectively blocks insects from entering the room through the ventilation opening 15, thus playing a role in physical isolation.

[0060] 2. Current repellency: When the fine mesh 1402 is connected to the battery pack 12, a closed circuit is formed. Once an insect touches the fine mesh 1402, the circuit is activated, generating a weak current that repels the insect, further preventing it from approaching or crossing the insect-proof net.

[0061] The inner side of the vent 15 opening is provided with a slot 1501 for fixing the insect net assembly 14. The depth of the slot 1501 is equal to the thickness of the insect net assembly 14.

[0062] The depth of the slot 1501 is measured to ensure that it is completely consistent with the thickness of the insect net assembly 14, thereby achieving a seamless fit. This design not only ensures the stable installation of the insect net assembly 14, but also avoids installation difficulties or loosening problems caused by size mismatch.

[0063] During installation, first align the insect net assembly 14 with the slot 1501, then gently press it down so that the edge of the insect net assembly 14 is fully embedded in the slot 1501. In this way, the insect net assembly 14 is firmly fixed to the inside of the vent 15, effectively preventing insects and other debris from entering the ventilation duct, while not affecting the ventilation effect.

[0064] The outer side of the base box 10 is evenly provided with fins to facilitate heat dissipation of the battery pack 12, and the battery pack 12 is composed of evenly arranged individual batteries connected in series.

[0065] The base box 10 of this invention has a circular structure with fins evenly arranged on its outer side to enhance heat dissipation. The battery pack 12 is placed inside the base box 10 and consists of multiple individual batteries connected in series.

[0066] The heat dissipation fins are evenly distributed on the outer side wall of the base box 10. The preferred material is aluminum alloy, which has good thermal conductivity and can effectively increase the heat dissipation area and improve heat dissipation efficiency.

[0067] The battery pack 12 is composed of several individual cells connected in series. The individual cells are preferably lithium-ion batteries, which have the characteristics of high energy density and long life, and meet the power supply requirements for a long time.

[0068] In this embodiment, the ventilation duct 2 is installed and fixed to the top of the greenhouse frame 1. Insect repellent is added to the insect repellent box 7 through the ventilation opening 15, and the repellent is injected into the insect repellent box 7 through the mesh of the breathable net 8. The insect-proof net assembly 14 is installed inside the slot 1501 of the ventilation opening 15, and the position of the insect-proof net assembly 14 is fixed by the fixing block 11. In actual use, the photovoltaic panel 6 can generate electricity under sunlight and transfer it to the battery pack 12 inside the base box 10 for storage, providing power to the ventilation fan 13 and the fine net 1402. The insect repellent box 7 contains insect repellent drugs, which are slowly released through the breathable net 8 to achieve the insect repellent effect. The ventilation fan 13 is activated to achieve ventilation inside and outside the greenhouse. The fine net 1402, with its high-density mesh structure, effectively blocks insects from entering the room through the ventilation opening 15, playing a role in physical isolation. When the fine net 1402 is connected to the battery pack 12, it forms a closed circuit. Once an insect touches the fine net 1402, the circuit is activated, generating a weak current that repels the insect, further preventing insects from approaching or crossing the insect-proof net.

[0069] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
