Description

Technical Field

[0001] This utility model relates to a pesticide delivery device, and more particularly to a device for secondary and multiple delivery of pesticides during long-term termite prevention treatment. Background Technology

[0002] Currently, the common method for preventing termites in buildings involves spraying or injecting various toxic chemicals—agents—horizontally and vertically during the foundation construction stage. These chemicals directly contact the termites to kill them. However, after several years, once the effects of the chemicals wear off, the termites will re-emerge and damage the building and furniture.

[0003] The publication number CN2579175Y discloses a multiple-application device for preventing termites, which consists of a main pipe and two or more layers of branch pipes. The main pipe connects to each layer of branch pipes, and the plane of the main pipe and the branch pipes forms an angle. The branch pipes have numerous small holes that communicate with the inner holes of the main pipe and the branch pipes. The beneficial effect of this device is that it can apply termite-preventing medicine multiple times, making the total efficacy of the medicine last longer. Because it uses two or more layers of branch pipes, the penetration surface of the medicine is wide and can penetrate evenly.

[0004] However, the above method can only deal with termites horizontally, without vertical branches, which makes it impossible to form a vertical termite barrier.

[0005] The publication number CN220859274U discloses a multiple-application termite prevention device, comprising multiple branch pipes and a termite supply assembly. Each branch pipe has multiple first-discharge holes, and the termite supply assembly includes a vertical pipe and multiple connecting parts. Each connecting part includes a slider, a locking bolt, and a flexible hose. In use, the vertical pipe and branch pipes are buried in the soil. Termite repellent is introduced into the vertical pipe, and the repellent in the vertical pipe is introduced into the branch pipes through the flexible hoses. The repellent is then discharged from the branch pipes into the soil through the first-discharge holes, thereby eliminating termites. The user can adjust the distance between adjacent branch pipes by sliding the slider according to the termite distribution density in the soil, thus adjusting the repellent distribution density.

[0006] However, the above method can only treat termites horizontally, without vertical branches and nozzles, which makes it impossible to form a vertical termite barrier. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of existing termite prevention technologies and provide a pesticide delivery device that is easy and quick to install and can provide long-lasting horizontal and vertical termite barriers.

[0008] The technical solution adopted by this utility model is:

[0009] This utility model discloses a termite-preventing agent delivery device, comprising multiple main pipes connected end-to-end via elbows to form a closed loop structure. The closed loop structure is connected to an injection pipe. Within the closed loop structure, multiple horizontal treatment pipes are connected, with each horizontal treatment pipe having its two ends connected to a corresponding main pipe via a tee. Multiple vertical treatment pipes are connected vertically to the upper and lower sides of each main pipe, with one end of each vertical treatment pipe connected to a corresponding main pipe via a tee and the other end being a closed structure. Multiple holes are formed in each of the horizontal and vertical treatment pipes, and a pressure nozzle is connected to each hole. Crushed stone filter material is filled around each pressure nozzle.

[0010] The beneficial effects of this utility model are as follows:

[0011] After the termite-preventing agent's effects dissipate several years later, it can be re-injected through a pump via an injection pipeline to achieve long-term termite control. This device is easy and quick to install; during the construction phase, the pipeline can be flexibly laid out according to the building's structural dimensions and shape, and the pipeline's direction and layout can be adjusted at any time.

[0017] 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] As shown in the attached diagram, this utility model discloses a termite-preventing agent delivery device. Multiple main pipes 2 are connected end-to-end via elbows to form a closed-loop structure. This closed-loop structure is connected to an injection pipe 1, which is used to connect to an external agent injection pipe. Multiple horizontal treatment pipes 3 are connected within the closed-loop structure. Each horizontal treatment pipe's two ends are connected to a corresponding main pipe via a tee 5. Multiple vertical treatment pipes 4 are connected vertically to the upper and lower sides of each main pipe. One end of each vertical treatment pipe is connected to a corresponding main pipe via a tee, and the other end is closed. Multiple holes are formed in each of the horizontal and vertical treatment pipes 4. A pressure nozzle 7 is connected to each hole. Crushed stone filter material is placed around each pressure nozzle to prevent soil from clogging the nozzle and affecting the agent spraying effect.

[0020] Preferably, multiple pressure nozzles on each horizontal or vertical treatment pipe are arranged in a staggered pattern. This staggered arrangement of the nozzles facilitates connection to the pipes and ensures more even spraying of the pesticide.

[0021] Horizontal or vertical irrigation pipes can also directly use commercially available drip irrigation pipes.

[0022] The direction and length of the main pipeline can be arranged according to the dimensions and layout of the building's underground structure. In one embodiment of this invention, the closed-loop structure is rectangular, with multiple horizontal treatment pipes arranged parallel to each other and connected at both ends to horizontal treatment pipes located on the two long sides of the rectangular structure. The elbows are right-angle elbows (6). These structures are commercially available and easy to install.

[0023] Preferably, the main pipeline is a 40mm diameter PE main pipeline, and the multiple horizontal and vertical treatment pipes are 20mm diameter PE pipes. This structure has excellent corrosion resistance, impact resistance, and flexibility, offers diverse and reliable connection methods, and has low construction costs.

[0024] Preferably, the pressure nozzle is one that automatically opens when pressure reaches 0.2 MPa. This ensures that the nozzle closes when there is no pressure, preventing debris from entering the pipeline.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
