Description

Technical Field

[0001] This utility model relates to the field of spiral nozzle technology, and in particular to a spiral nozzle structure. Background Technology

[0002] Spiral sprinklers are widely used in various fields such as industrial production, agricultural irrigation, and fire fighting because they can create a spiral spray effect on liquids, improving the coverage and uniformity of the spray. Existing spiral sprinklers typically consist of a connecting seat, a guide tube, and a spiral spray structure. They achieve spraying by the flow of liquid within the spiral channel. However, in actual use, these sprinklers have revealed many problems. For example, when not in operation, the spiral spray structure is directly exposed to the external environment, making it prone to accumulating dust and debris, or even being damaged by impacts, leading to blockage of the liquid outlet or a decrease in spraying effect, affecting subsequent use. In addition, most spiral sprinklers lack a flexible on / off control structure. After the liquid delivery system is turned on, the on / off control must be achieved through an external valve, which is cumbersome and has a slow response.

[0003] Therefore, it is necessary to provide a new spiral nozzle structure to solve the above-mentioned technical problems. Utility Model Content

The guide tube and the spiral tube are interconnected, and a plurality of evenly distributed liquid outlets are opened on the spiral tube.

[0006] A piston rod with elastic connection is installed inside the guide tube, and a central connecting rod is fixedly installed at the bottom of the piston rod. The bottom end of the central connecting rod extends out of the guide tube and is fixedly installed with an upward-opening protective cover.

[0007] Preferably, the piston rod is slidably connected to the inner cavity of the guide tube, and a spring is provided at the bottom of the piston rod.

[0008] Preferably, the spring is sleeved on the central connecting rod, one end of the spring is fixedly connected to the lower cylindrical surface of the piston rod, and the other end of the spring is fixedly installed with a connecting ring, which is fixedly installed on the inner bottom wall of the guide tube.

[0012] Compared with related technologies, the spiral nozzle structure provided by this utility model has the following beneficial effects:

[0013] When in operation, the liquid pressure of this invention pushes the piston column downward, simultaneously causing the protective cover to move down and expose the spiral tube, thus achieving automatic linkage between opening the spray channel and disengaging the protection. After stopping operation, the spring resets and drives the piston column to slide upward, both sealing the interface between the guide tube and the spiral tube and resetting the protective cover to provide protection. No manual operation is required, and the response is rapid. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 5 The present invention provides a spiral nozzle structure, which includes a threaded connecting seat 1, a guide tube 2, a spiral tube 3, and a protective cover 6.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 5 The threaded connector 1 is fixedly installed with a guide tube 2, and the side wall of the guide tube 2 is connected with a spiral tube 3. The guide tube 2 and the spiral tube 3 are interconnected, and the spiral tube 3 has several evenly distributed liquid outlets 3a. The threaded connector 1 and the guide tube 2 are fixedly installed with an abutment plate 11.

[0024] A piston rod 4 with elastic connection is installed inside the guide tube 2, and a central connecting rod 5 is fixedly installed at the bottom of the piston rod 4. Specifically, the piston rod 4 is slidably connected to the inner cavity of the guide tube 2, and a spring 7 is provided at the bottom of the piston rod 4. The spring 7 is sleeved on the central connecting rod 5. One end of the spring 7 is fixedly connected to the lower cylindrical surface of the piston rod 4, and a connecting ring 8 is fixedly installed at the other end of the spring 7. The connecting ring 8 is fixedly installed on the inner bottom wall of the guide tube 2. The bottom rod head of the central connecting rod 5 extends out of the guide tube 2 and is fixedly installed with an upward-opening protective cover 6.

[0025] It should be noted that: when the spiral nozzle is not discharging liquid, the piston rod 4 slides up to the maximum height along the inner cavity of the guide tube 2 under the action of the spring 7. At this time, the piston rod 4 blocks the interface between the guide tube 2 and the spiral tube 3, and the protective cover 6 completely covers the spiral tube 3, thereby effectively protecting the spiral tube 3 and effectively avoiding damage to the spiral tube 3 and the outlet 3a caused by dust, debris and external collisions, and reducing the risk of the spiral tube 3 becoming blocked.

[0026] When this spiral nozzle discharges liquid, the liquid enters the guide tube 2 and pushes down the piston column 4, thereby driving the spring 7 to compress. At the same time, the connecting rod 5 drives the protective cover 6 to slide down, exposing the spiral tube 3. After the piston column 4 slides down past the interface between the guide tube 2 and the spiral tube 3, the liquid flows into the spiral tube 3 and is discharged out through the outlet 3a.

[0027] Therefore, during operation, the liquid pressure pushes the piston column 4 downward, simultaneously causing the protective cover 6 to move down and expose the spiral tube 3, thus achieving automatic linkage between opening the spray channel and removing the protection. After operation stops, the spring 7 resets and drives the piston column 4 to slide upward, which not only blocks the interface between the guide tube 2 and the spiral tube 3, but also causes the protective cover 6 to reset and provide protection. No manual operation is required, and the response is rapid.

[0028] Furthermore, an annular groove 11a is formed on the lower ring surface of the abutment plate 11, so that when the piston rod 4 slides up to the maximum height along the inner cavity of the guide tube 2 under the action of the spring 7, the cover opening of the protective cover 6 can abut against the annular groove 11a formed on the abutment plate 11.

[0029] Furthermore, the bottom of the protective cover 6 is provided with several annularly distributed liquid discharge ports 6a, which can discharge some of the liquid that flows out from the spiral tube 3 and falls into the protective cover 6.

[0030] In addition, to eliminate the potential risk of spring 7 rusting and losing its elasticity due to contact with water, spring 7 is made of stainless steel or titanium alloy to improve corrosion resistance. At the same time, a polytetrafluoroethylene (PTFE) coating is applied to the surface of spring 7 to enhance its rust prevention ability.

[0031] The working principle of the spiral nozzle structure provided by this utility model is as follows:

[0032] The spiral nozzle is fixedly connected to the drain pipe by the threaded connector 1. When the spiral nozzle is not draining, the piston 4 slides up to its maximum height along the inner cavity of the guide tube 2 under the action of the spring 7. At this time, the piston 4 blocks the interface between the guide tube 2 and the spiral tube 3, and the protective cover 6 completely covers the spiral tube 3, thereby effectively protecting the spiral tube 3 and preventing damage to the spiral tube 3 and the outlet 3a caused by dust, debris, and external collisions, reducing the risk of the spiral tube 3 becoming blocked. When the spiral nozzle is draining, the water enters the guide tube 2 and pushes the piston 4 down, thereby driving the spring 7 to compress. At the same time, the connecting rod 5 drives the protective cover 6 to slide down, exposing the spiral tube 3. After the piston 4 slides down past the interface between the guide tube 2 and the spiral tube 3, the liquid flows into the spiral tube 3 and is discharged from the outlet 3a.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
