Technical Field
[0001] This utility model relates to the field of water feature equipment technology, specifically to an automatic lifting slit sprinkler head. Background Technology
[0002] Water feature nozzles are a crucial component of water feature projects. They come in various types and have different functions, creating a wide range of water feature effects. According to the spray pattern, they can be divided into direct spray nozzles, fountain nozzles, fan-shaped nozzles, flower-shaped nozzles, etc.
[0003] In response to this, invention patent CN111282764B discloses a water feature nozzle, relating to the field of water feature equipment technology. This water feature equipment includes a nozzle body; an inlet and an outlet are respectively provided on the end faces of both ends of the nozzle body; the outlet includes a circular nozzle for forming a water jet and an elongated slot for forming a water film, the circular nozzle and the elongated slot being connected. When the water feature nozzle provided by this invention is connected to a high-pressure water source, high-pressure water enters through the inlet of the nozzle body and is then sprayed out through the outlet of the nozzle body. Because the outlet is formed by the interconnected circular nozzle and elongated slot, the high-pressure water is sprayed out through the circular nozzle to form a water jet and through the elongated slot to form a water film. Therefore, the water feature nozzle provided by this invention can spray a water pattern that combines both a water film and a water jet.
[0004] However, the nozzles in the aforementioned patent applications still have some problems: current water feature nozzles do not have an automatic lifting function. When the nozzles are not in use, they cannot be hidden underwater and are exposed, affecting the overall effect of the water feature and causing inconvenience in their use. Utility Model Content
[0005] In order to solve the above problems, the purpose of this utility model is to provide an automatic lifting gap nozzle to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model proposes an automatic lifting slit nozzle, including a connecting pipe, wherein a T-shaped external threaded ring is threadedly connected to the top of the inner wall of the connecting pipe;
[0007] A movable tube is inserted inside the T-shaped external threaded ring. A movable disc is fixed at the bottom end of the movable tube. A connecting screw hole is opened in the middle of the bottom end of the movable disc. Multiple evenly distributed water passage holes are opened on the side of the bottom end of the movable disc. An inner tube is threaded into the connecting screw hole. A T-shaped head is threaded into the top of the inner wall of the inner tube.
[0008] In a preferred embodiment of this invention, the outer wall of the T-shaped head is interlocked with the inner wall of the movable tube, forming a water flow channel between the T-shaped head and the movable tube.
[0009] As a preferred technical solution of this utility model, the four corners of the outer wall of the T-shaped outer threaded ring are provided with disassembly and assembly openings, and a retaining ring is fixedly provided at the bottom of the inner wall of the connecting pipe, the outer diameter of the retaining ring being larger than the outer diameter of the movable disc.
[0010] As a preferred embodiment of this utility model, a circular opening is provided on the side of the top of the movable disc, and a sealing ring is fitted inside the circular opening.
[0011] As a preferred embodiment of this utility model, an inner threaded ring is fixedly provided on the side of the bottom end of the connecting pipe, and the outer diameter of the inner threaded ring is the same as the outer diameter of the connecting pipe.
[0012] Compared with the prior art, the present invention provides an automatic lifting slit nozzle, which has the following beneficial effects:
[0013] 1. This automatic lifting and lowering spout nozzle is connected to a T-shaped external threaded ring via an internal threaded connection to a connecting pipe. A movable pipe is inserted inside the T-shaped external threaded ring and connected to a movable disc. The inner pipe connected to the movable disc is threaded with a T-shaped head. The movable disc has multiple water passage holes. When the nozzle is in use, the water pump supplies water to the connecting pipe. The water acts on the movable disc, which in turn raises the movable pipe and the inner pipe. When the water supply stops, the movable disc lowers the movable pipe and the inner pipe under gravity, giving the nozzle an automatic lifting and lowering function. When the nozzle is not in use, it can be hidden underwater to prevent it from being exposed and to ensure the overall effect of the water feature.
[0014] 2. This automatic lifting slit nozzle is connected to a T-shaped external threaded ring via an internal threaded connection to a connecting pipe. A movable tube is inserted inside the T-shaped external threaded ring and connected to a movable disc. The inner tube of the movable disc is threaded with a T-shaped head. The movable disc has multiple water passage holes, enabling the nozzle to have an automatic lifting function. When the nozzle is not in use, it can be hidden underwater to prevent it from being exposed to wind and sun, thus reducing its corrosion rate and extending its service life.

[0020] The technology of the present invention will now be described with reference to the accompanying drawings of the embodiments thereof.
[0021] The solution is described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0022] Example 1
[0023] like Figures 1-3 As shown, an embodiment of this utility model proposes an automatic lifting gap nozzle, including a connecting pipe 1, with a T-shaped external threaded ring 2 threadedly connected to the top of the inner wall of the connecting pipe 1;
[0024] A movable tube 4 is inserted inside the T-shaped outer screw ring 2. A movable disc 8 is fixed at the bottom end of the movable tube 4. A connecting screw hole 11 is opened in the middle of the bottom end of the movable disc 8, and multiple evenly distributed water passage holes 10 are opened on the side of the bottom end of the movable disc 8. An inner tube 7 is threadedly connected to the connecting screw hole 11. A T-shaped head 6 is threadedly connected to the top of the inner wall of the inner tube 7. When water is supplied to the nozzle, some water flows into the inner tube 7. The water flow is blocked by the T-shaped head 6. The movable disc 8 has water passage holes 10. The movable disc 8 blocks part of the water flow, which can generate pressure to make the movable disc 8 and the movable tube 4 on it move upward.
[0025] The outer wall of the T-shaped head 6 is inserted and connected to the inner wall of the movable pipe 4, forming a water flow channel between the T-shaped head 6 and the movable pipe 4. The four corners of the outer wall of the T-shaped outer threaded ring 2 are provided with disassembly and assembly openings 3. Through the cooperation of multiple disassembly and assembly openings 3, it is convenient for personnel to disassemble and assemble the T-shaped outer threaded ring 2. A retaining ring 12 is fixedly provided at the bottom of the inner wall of the connecting pipe 1. The outer diameter of the retaining ring 12 is larger than the outer diameter of the movable plate 8. A circular opening is provided on the side of the top of the movable plate 8. A sealing ring 9 is fitted inside the circular opening. An inner threaded ring 5 is fixedly provided on the side of the bottom of the connecting pipe 1. The outer diameter of the inner threaded ring 5 is the same as the outer diameter of the connecting pipe 1.
[0026] Example 2
[0027] like Figures 1-3As shown, the T-head 6 and the movable pipe 4 form a water flow channel. If the water flow used by the nozzle contains a lot of impurities, an automatically resetting mud-blocking structure can be set at the top of the T-head 6. The automatically resetting mud-blocking structure is as follows: a limiting cavity is opened in the middle of the top of the T-head 6, a baffle is inserted through the inner wall of the limiting cavity, a movable column is provided at the top of the baffle, and a reset spring for resetting is sleeved on the outer wall of the movable column. At the same time, the movable column passes through the limiting cavity and a circular mud-blocking cover with an outer diameter greater than or equal to the outer diameter of the movable pipe 4 is set at its top. When the nozzle is in use, the mud-blocking cover is lifted by the water pressure. At this time, the reset spring is compressed, thus ensuring that the water flow is sprayed out. When the nozzle is not supplying water, the mud-blocking cover is covered on the top of the movable pipe 4 and the T-head 6 by the elastic force of the reset spring, thus preventing mud and other impurities from entering the nozzle through the water flow channel.
[0028] Working principle: When using this nozzle, the water pump's water supply pipe is threaded to the inner threaded ring 5, and the connecting screw hole 11 of the movable disc 8 is threaded to the inner tube 7. At the same time, the inner tube 7 is threaded to a T-shaped head 6. When the water pump supplies water to the nozzle, the water flow enters the connecting pipe 1. The movable disc 8 has a water passage hole 10. The movable disc 8 blocks part of the water flow, while part of the water flow enters the inner tube 7. The water flow is blocked by the T-shaped head 6, which generates pressure to move the movable disc 8 and its movable pipe 4 upward, thereby causing the movable pipe 4, the inner tube 7, and the T-shaped head 6 to rise and extend above the water surface. Part of the water flow enters the movable pipe 4 through the water passage hole 10. The water flows out through the water flow channel formed by the movable pipe 4 and the T-shaped head 6. Under its own gravity, the water can spray out in a mushroom shape. When the water supply stops, under the action of gravity, the movable disc 8 drives the movable pipe 4 and the inner tube 7 to move downward, which can hide the nozzle underwater, preventing the nozzle from being exposed and ensuring the overall effect of the water feature.
