Technical Field

[0001] This utility model relates to the field of termite control technology, specifically to a multiple-application device for termite prevention. Background Technology

[0002] One existing method for preventing termites is to set up termite-proof lines around the object to be protected, forming a toxic soil barrier that prevents termites from approaching. Multiple applications of the pesticide are required during installation to ensure sufficient efficacy.

[0003] However, traditional methods of applying pesticides mostly involve manually spraying the pesticide onto the soil. The pesticide is difficult to penetrate deep into the soil and is unevenly distributed, allowing termites to pass through areas where the pesticide is less effective. Utility Model Content

[0004] The purpose of this invention is to provide a multiple-application device for preventing termites, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multiple-dose termite prevention device, comprising an infusion tube, and further comprising,

[0006] An extension tube is provided, with a limiting ring fixedly connected to one side of the extension tube, a connecting tube fixedly connected to the side of the limiting ring away from the extension tube, a spray tube slidably connected to the inner wall of the extension tube, a sealing plate fixedly connected to one side of the spray tube, a needle fixedly connected to the other side of the spray tube, an opening provided on the sealing plate, an L-shaped baffle rotatably connected to the inner side of the sealing plate via a torsion spring, the L-shaped baffle fitting against the opening of the opening on the inner side of the sealing plate, the side of the spray tube away from the sealing plate fitting against the inner side of the limiting ring, and the side of the extension tube away from the connecting tube fixedly connected to the side of the infusion tube.

[0007] The liquid distribution chamber has electric tee valves fixedly connected to both sides. The side of the electric tee valve away from the liquid distribution chamber is fixedly connected to the infusion tube 2. The bottom of the electric tee valve is fixedly connected to the liquid distribution tube, and the bottom of the liquid distribution tube is fixedly connected to the top of the infusion tube 1.

[0008] Preferably, the side of the extension tube away from the limiting ring one is fixedly connected to the limiting ring two, and the side of the sealing plate away from the spray pipe is attached to the side of the limiting ring two.

[0009] Preferably, a limiting ring is fixedly connected to the outer side of the connecting tube away from the limiting ring, and a plastic film is fixedly sleeved on the side of the connecting tube away from the limiting ring, with the edge of the plastic film adhering to the surface of the limiting ring.

[0010] Preferably, the needle tip has side nozzles on both sides.

[0011] Preferably, the bottom of the dispensing chamber is rotatably connected to a screw via a bearing, the lower end of the screw is threaded to a threaded tube, one side of the infusion tube is fixedly connected to the side of the threaded tube, and a knob ring is fixedly sleeved on the upper surface of the screw.

[0012] Preferably, a base is fixedly connected to the bottom of the threaded tube, and a support rod is fixedly connected to the side of the base.

[0013] Preferably, the top of the liquid distribution chamber is fixedly connected to an inlet pipe, and the top of the inlet pipe is threaded with a top cover.

[0014] Preferably, an atomizing nozzle is fixedly connected to the bottom of the second infusion tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a spray pipe, needles, and atomizing nozzles to increase air and hydraulic pressure by injecting liquid into the first infusion pipe. This opens the L-shaped baffle, allowing gas and liquid to enter the spray pipe through the opening. The liquid is then discharged into the soil through the needles. Side nozzles on both sides of the needles ensure more even liquid distribution. The two infusion pipes on both sides of the threaded pipe, along with the two rows of needles on both sides of the infusion pipes, ensure even distribution of the liquid in the soil, improving the termite control effect. The atomizing nozzles then spray the liquid evenly onto the ground to control termites.

[0017] This invention uses an L-shaped baffle and a torsion spring to close the side valve of the electric three-way valve. An air pump draws air out of the infusion tube, creating a negative pressure inside the tube, which draws the needle into the connecting tube. This makes it easier to remove the infusion tube from the soil, prevents the needle from breaking, and allows for reuse. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a multiple-use insecticide application device for termite prevention, including an infusion tube 1, and further comprising...

[0026] Extension tube 2, with a limiting ring 3 fixedly connected to one side of extension tube 2, and a connecting tube 4 fixedly connected to the side of the limiting ring 3 away from extension tube 2. A spray tube 7 is slidably connected to the inner wall of extension tube 2, and a sealing plate 8 is fixedly connected to one side of spray tube 7. A needle 11 is fixedly connected to the other side of spray tube 7. The sealing plate 8 has an opening 9. An L-shaped baffle 10 is rotatably connected to the inner side of the sealing plate 8 via a torsion spring. The L-shaped baffle 10 fits into the opening of the opening 9 on the inner side of the sealing plate 8. The size of the L-shaped baffle 10 is slightly larger than the opening 9, so it can only be opened in one direction. The side of spray tube 7 away from the sealing plate 8 fits into the inner side of the limiting ring 3. The side of extension tube 2 away from the connecting tube 4 is fixedly connected to the side of infusion tube 1.

[0027] Liquid separation chamber 17, electric tee 20 is fixedly connected to both sides of liquid separation chamber 17, infusion tube 22 is fixedly connected to the side of electric tee 20 away from liquid separation chamber 17, liquid separation tube 21 is fixedly connected to the bottom of electric tee 20, and the bottom of liquid separation tube 21 is fixedly connected to the top of infusion tube 1.

[0028] The side of the extension tube 2 away from the limiting ring 3 is fixedly connected to the limiting ring 2 13. The side of the sealing plate 8 away from the spray tube 7 is attached to the side of the limiting ring 2 13. The limiting ring 2 13 limits the sealing plate 8 to prevent the spray tube 7 from sliding out of the extension tube 2 when the infusion tube 1 is sucked in.

[0029] A limiting ring 6 is fixedly connected to the outer side of the connecting tube 4 away from the limiting ring 3. A plastic film 5 is fixedly sleeved on the side of the connecting tube 4 away from the limiting ring 3. The edge of the plastic film 5 is attached to the surface of the limiting ring 6 to facilitate the fixing of the plastic film 5. The plastic film 5 seals the opening of the connecting tube 4. When the infusion tube 1 and the extension tube 2 are buried in the soil, it prevents the soil from entering the connecting tube 4 and affecting the movement of the spray tube 7. In addition, the plastic film 5 is easily punctured by the needle 11.

[0030] Side nozzles 12 are provided on both sides of the tip of the needle 11 to further improve the uniformity of spraying.

[0031] The bottom of the liquid distribution chamber 17 is rotatably connected to a screw 15 via a bearing. The lower end of the screw 15 is threadedly connected to a threaded tube 14. One side of the infusion tube 1 is fixedly connected to the side of the threaded tube 14. A knob ring 16 is fixedly sleeved on the upper surface of the screw 15. Rotating the screw 15 can adjust the height of the liquid distribution chamber 17, thereby adjusting the depth of the infusion tube 1 buried underground or adjusting the height of the infusion tube 22 above the ground.

[0032] A base 24 is fixedly connected to the bottom of the threaded pipe 14, and a support rod 25 is fixedly connected to the side of the base 24 to increase the support area and prevent the threaded pipe 14 from tipping over.

[0033] The top of the liquid distribution chamber 17 is fixedly connected to the liquid inlet pipe 18. The top of the liquid inlet pipe 18 is threaded with the top cover 19. The liquid inlet pipe 18 is connected to the liquid tank. The liquid is fed into the liquid inlet pipe 18 by a liquid pump. Alternatively, the liquid inlet pipe 18 can be connected to an air pump to suck out the air in the infusion tube 1, so that the needle 11 can be retracted into the connecting tube 4.

[0034] The bottom of the infusion tube 22 is fixedly connected to an atomizing nozzle 23, which atomizes the medicine, expands the spraying area, and evenly sprays the medicine onto the ground.

[0035] Working principle: First, dig a strip-shaped pit in the soil of the prevention and control area. Place the infusion tube 1 in the pit. The base 24 and support rod 25 provide support and improve stability. Then, fill the pit with soil to bury the infusion tube 1. By holding the knob ring 16 and turning the screw 15, the distance between the dispensing chamber 17 and the infusion tube 1 can be adjusted, which can adjust the height of the dispensing chamber 17 on the ground and the burial depth of the infusion tube 1. When the pit is dug deep, the infusion tube 22 is still above the ground when the base 24 touches the bottom of the pit. Then, rotate the top cover 19 to remove it from the inlet pipe 18. Connect the inlet pipe 18 to the liquid pump and the medicine tank through the pipe. In the initial state, the electric three-way valve 20 closes the pipe leading to the infusion tube 22 and opens the pipe leading to the dispensing pipe 21.

[0036] The medicine is pumped into the dispensing chamber 17. The medicine then flows through the electric three-way valve 20 into the dispensing pipe 21 and then into the infusion pipe 1. The air and hydraulic pressure in the infusion pipe 1 gradually increases, pushing the sealing plate 8 and the spray pipe 7 outwards. This causes the tip of the needle 11 to pierce the plastic film 5 and penetrate into the soil until the spray pipe 7 is blocked by the limiting ring 3. The medicine continues to be pumped in, and the air and hydraulic pressure in the infusion pipe 1 continues to increase, pushing open the L-shaped baffle 10. Gas and medicine enter the spray pipe 7 through the port 9, and then are discharged into the soil through the needle 11. The side nozzles 12 on both sides of the needle 11 ensure more even distribution of the medicine. The two nozzles on both sides of the threaded pipe 14... The infusion tube 1 and the two rows of needles 11 on both sides of the infusion tube 1 ensure that the liquid medicine is evenly distributed in the soil, improving the control effect on termites. After the needles 11 have been dispensing the medicine for a period of time, the side valve of the electric three-way valve 20 is opened, so that the liquid medicine is fed into the infusion tube 22 and sprayed out through the atomizing nozzle 23, so that the liquid medicine is evenly sprayed on the ground to control termites on the ground. The medicine can be supplied multiple times by the liquid pump, eliminating the need for manual spraying. This solves the problem that traditional medicine supply methods mostly involve manually spraying medicine on the soil, which makes it difficult for the medicine to penetrate deep into the soil and results in uneven distribution, allowing termites to pass through areas with weak medicine effect.

[0037] When it is necessary to remove the infusion tube 1, stop the infusion for a period of time, connect the infusion tube 18 to the air pump to introduce air into the dispensing chamber 17, the second infusion tube 22 and the first infusion tube, so that the inside is dried quickly. Then close the side valve of the electric three-way valve 20, and use the air pump to suck out the air in the first infusion tube, so that the inside of the first infusion tube is negatively pressured, thereby sucking the needle 11 into the connecting tube 4, making it easier to remove the first infusion tube from the soil and preventing the needle 11 from breaking. The second limiting ring 13 blocks the sealing plate 8 to prevent the spray tube 7 from sliding into the first infusion tube.
