Description

Technical Field

[0001] This utility model relates to an inverted built-in anti-drip atomizing micro-nozzle, belonging to the technical field of anti-drip micro-nozzle. Background Technology

[0002] Inverted micro-sprinklers are an irrigation method that suspends micro-sprinklers above plants for spraying. Different sprinklers can be selected to meet the water requirements or other needs of different crops. Inverted micro-sprinklers allow for precise control of the irrigation process by controlling the water flow. Compared to traditional drip irrigation and sprinkler irrigation, inverted micro-sprinklers offer more precise control, resulting in better irrigation effects. However, existing inverted micro-sprinklers are mostly equipped with external anti-drip valves, leading to a high failure rate and frequent replacements, increasing usage and maintenance costs, reducing work efficiency, and contradicting the principle of cost reduction and efficiency improvement. Therefore, designing an inverted micro-sprinkler with a built-in anti-drip atomizing valve is essential. Utility Model Content

[0003] This utility model addresses the shortcomings of the existing technology by providing an inverted, built-in anti-drip atomizing micro-nozzle.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] The inverted built-in anti-drip atomizing micro-nozzle includes a detachable cap and a nozzle. The nozzle is provided with several nozzles and has an internal lower support. The lower support has conical grooves corresponding to the nozzles, and each conical groove has a connected flow channel. The lower support has a top groove, and a constant pressure plate, a top rod, and a spring are sequentially connected between the top groove and the cap.

[0006] Furthermore, the top groove has several recesses on the side that contacts the constant pressure plate.

[0007] Furthermore, the number of the recesses is the same as the number of nozzles.

[0008] Furthermore, the location of the recess corresponds to the inlet of the flow channel.

[0009] Furthermore, the constant pressure plate is made of silicone.

[0010] Furthermore, a vertical shaft is provided at the lower end of the top groove, and the vertical shaft passes through the upper end face of the lower support.

[0011] Furthermore, the center of each conical groove is on the same horizontal line as the center of the nozzle.

[0012] Furthermore, the number of nozzles is two, symmetrically arranged on both sides of the nozzle head.

[0013] Furthermore, the number of nozzles is four, symmetrically arranged in the radial direction of the nozzle head.

[0014] Furthermore, the cap and the nozzle are connected by a thread.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: It can meet the atomization needs in greenhouses, such as cooling, humidification, and insecticide spraying for daily crop applications. It has excellent coverage, ensures uniform liquid spraying distribution, and has high work efficiency. It saves the need for external anti-drip valves, avoiding frequent replacements of the previous anti-drip valves. It also has an anti-drip function, preventing dripping during use and at the end. When working in pulse mode, it is used to wet the smallest droplets on the smallest leaves, resulting in stable spraying and good performance. Micro-nozzles with two or four nozzles can be selected according to specific needs, making it highly practical. By setting a lower support and a top groove to cooperate, an anti-drip effect is achieved, replacing the external anti-drip valve, resulting in high work efficiency and good practicality. By setting a constant pressure plate, the upper and lower pressures are balanced during use. The material is silicone, which has good performance, excellent wear resistance, and a longer service life. Attached Figure Description

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1-6As shown, the inverted built-in anti-drip atomizing micro-nozzle includes a detachably connected cap 1 and a nozzle 7. The nozzle 7 is provided with a plurality of nozzles 71 and a lower support 6 inside. The lower support 6 is provided with a conical groove 62 corresponding to the nozzles 71. Each conical groove 62 is provided with a connected flow channel 61. The lower support 6 is provided with a top groove 5. A constant pressure plate 4, a top rod 3 and a spring 2 are connected in sequence between the top groove 5 and the cap 1.

[0025] The top groove 5 has several recesses on the side that contacts the constant pressure plate 4.

[0026] The number of the depressions is the same as the number of the nozzles 71.

[0027] The location of the recess corresponds to the inlet of the flow channel 61.

[0028] The constant pressure plate 4 is made of silicone.

[0029] The lower end of the top groove 5 is provided with a vertical shaft, which passes through the upper end face of the lower support 6.

[0030] The center of the conical groove 62 is on the same horizontal line as the center of the nozzle 71.

[0031] There are two nozzles 71, which are symmetrically arranged on both sides of the nozzle 7.

[0032] The number of nozzles 71 is four, symmetrically arranged in the radial direction of the nozzle 7.

[0033] The cap 1 and the nozzle 7 are connected by threads.

[0034] During operation, select two or four micro-nozzles 71 according to actual needs, place the lower bracket 6 in the nozzle 7, place the top groove 5 in the lower bracket 6, and connect the spring 2 through the upper end of the top rod 3 to the cap 1. Finally, place the constant pressure plate 4 between the top groove 5 and the top rod 3, and tighten the cap 1 and nozzle 7 with threads. The micro-nozzle assembly is complete. Then connect the connector 72 to the standard parts on the water pipe, start the valve, and the water or agent flows into the micro-nozzle through the connector 72. The constant pressure plate 4 plays a constant pressure role, and finally sprays out through the nozzle 7. When working in pulse mode, it is used to wet the smallest droplets of the smallest blades. The spraying effect is stable. When the valve is closed, the liquid inside the water pipe will not drip due to the action of the internal structure.

[0035] It can meet the atomization needs in greenhouses, such as cooling, humidification, and pesticide spraying for daily crop applications. It has excellent coverage, ensures uniform spray distribution, and has high work efficiency. It saves the need for an external anti-drip valve, avoiding frequent replacements of the previous anti-drip valve. It also has an anti-drip function, preventing dripping during use and termination. When working in pulse mode, it is used to wet the smallest droplets on the smallest leaves, with stable spraying effect and good performance. Two or four micro-nozzles 71 can be selected according to specific needs, making it highly practical. By setting the lower bracket 6 and the top groove 5 to cooperate, the anti-drip effect is achieved, replacing the external anti-drip valve, which has high work efficiency and good practicality. By setting the constant pressure plate 4, the upper and lower pressure is balanced during use. The material is silicone, which has good performance, good wear resistance, and a longer service life.
