DETAILED DESCRIPTION

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

[0022] See also Figure 1-5 , the utility model provides a technical solution:

[0023] An insect-proof net with a drug-slow-release function comprises an insect-proof net body 1 and side strips 2, wherein the insect-proof net body 1 is formed by interweaving a plurality of groups of longitudinal mesh wires 101 and a plurality of groups of transverse mesh wires 102, wherein the two ends of the plurality of groups of longitudinal mesh wires 101 and the plurality of groups of transverse mesh wires 102 are respectively fixedly connected to the inner wall of the side strips 2, a drug-filling cavity 3 is arranged inside the side strips 2, the plurality of groups of longitudinal mesh wires 101 are hollow, and the plurality of groups of longitudinal mesh wires 101 are all connected to the inside of the drug-filling cavity 3, and a plurality of groups of slow-release openings 4 are opened on the outer walls of the plurality of groups of longitudinal mesh wires 101. The utility model can realize long-term prevention and control of pests by continuously releasing drugs through the coordinated use of the side strips 2, the drug-filling cavity 3, the longitudinal mesh wires 101 and the slow-release openings 4, thereby effectively preventing the invasion of pests and avoiding the potential safety hazards caused by excessive use of pesticides;

[0024] An inner core 5 is arranged inside the plurality of groups of longitudinal meshes 101. The material of the inner core 5 is set to be made of a high molecular polymer. By setting the inner core 5, the high molecular polymer has good biocompatibility and controllable degradation rate, and the release rate and cycle of the drug can be designed according to needs;

[0025] An annular groove 6 is provided on the inner wall of the plurality of groups of sustained-release openings 4, and a water-absorbing resin 7 is provided inside the plurality of groups of annular grooves 6. By providing the annular grooves 6 and the water-absorbing resin 7 in cooperation with each other, when the water-absorbing resin 7 encounters rainwater, it will rapidly swell and form a gel-like substance, and the gel-like substance will rapidly block the sustained-release opening 4. Due to the compact structure of the gel, rainwater will not penetrate into the inner cavity of the longitudinal mesh 101 through the sustained-release opening 4, thereby preventing the drug in the inner cavity of the longitudinal mesh 101 from being diluted, thereby ensuring the efficacy of the sustained-release drug. After the rain stops and the sky clears, the water begins to evaporate, and the water-absorbing resin 7 will gradually release the water and shrink to its original size or close to its original size, at which time the sustained-release opening is restored to be unobstructed;

[0026] It should be noted that the water-absorbing resin 7 will lose its ability to absorb water once it has been used, but its water-absorbing performance can be restored by regeneration. The regeneration method of the water-absorbing resin 7 mainly includes a physical method, which includes a water washing method and a drying method. The water washing method is to repeatedly rinse the water-absorbing resin 7 with clean water and then place it to dry. The drying method is to place the water-absorbing resin 7 in the air to dehydrate it naturally. This method is simple to operate and low in cost, and can restore its water-absorbing capacity.

[0027] The longitudinal mesh 101 includes an inner layer 1011 , and a wear-resistant layer 1012 is disposed on the outer side of the inner layer 1011 ;

[0028] The material of the inner layer 1011 is set to be made of polypropylene, which is a lightweight, high-strength plastic material with excellent corrosion resistance, wear resistance and flame retardancy. The polypropylene insect-proof net is not only light and easy to carry, but also has a long service life and can maintain a good insect-proof effect under different environmental conditions. In addition, the polypropylene material can also be combined with other drug sustained-release technologies to achieve sustained release of drugs;

[0029] The material of the wear-resistant layer 1012 is set to be made of polyester fiber. Polyester fiber is a kind of synthetic fiber with excellent performance, has excellent UV resistance and aging resistance, and can withstand a certain weight and external pressure. The insect-proof net made of this material is not only durable, but also suitable for long-term use in outdoor environments. The fine density of polyester fiber is high, which can effectively prevent the invasion of pests;

[0030] The material of the transverse mesh 102 is set to be made of glass fiber. Glass fiber is a corrosion-resistant, heat-resistant, and easy-to-clean material, suitable for places that require high strength and durability. The glass fiber insect-proof net has a long service life and good stability, and can protect crops from pests under harsh environmental conditions;

[0031] A plurality of through holes 8 adapted to the longitudinal mesh 101 are respectively provided on the inner walls of both sides of the side strip 2. The two ends of the longitudinal mesh 101 are respectively fixedly plugged into the inside of the through holes 8. The inner cavity of the longitudinal mesh 101 is connected with the inside of the drug filling cavity 3 through the through holes 8, so that the drug can flow into the inner cavity of the longitudinal mesh 101.

[0032] It also includes a drug adding tube 9, which is fixedly connected to the top of the edge strip 2. A sealing plug 10 is provided on the top of the drug adding tube 9. Drugs can be added to the inside of the drug filling cavity 3 through the drug adding tube 9. The drugs can be low-toxic, high-efficiency, and environmentally friendly biological pesticides or plant-based pesticides. These pesticides have less harm to the environment and human health while preventing and controlling pests.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
