[0031] Please see Figure 1-5 This utility model provides a technical solution: a self-sprinkling device with variable angle and flow rate, comprising:
[0032] The outer shell 100 has a cavity inside for accommodating components such as the connecting pipe 200. The outer shell 100 has multiple through holes 101, which allow the nozzle 203 to extend out of the outer shell 100 for spraying. A rubber sealing ring 102 is provided along the edge of the through hole 101 to ensure the sealing between the nozzle 203 and the outer shell 100 and prevent liquid leakage.
[0033] Connecting pipe 200, the connecting pipe 200 is disposed inside the outer casing 100;
[0034] The connecting pipe 200 includes an inlet pipe 201 and a nozzle 202. The inlet pipe 201 is used to introduce liquid into the nozzle 202. The nozzle 202 is fixedly connected to the inlet pipe 201 to ensure stable liquid transmission. The nozzle 202 and the inlet pipe 201 are fixedly connected. Multiple nozzles 203 are slidably connected to the nozzle 202. These nozzles 203 can slide on the nozzle 202. The multiple nozzles 203 can be synchronously raised and lowered for angle adjustment and cooperate to achieve all-round spray coverage to adapt to different spraying needs. The multiple nozzles 203 are all slidably connected to the nozzle 202. The nozzle 202 is uniformly provided with grooves 204 along the cross-sectional arc. Each of the multiple nozzles 203 has a locking block 205 on its outer surface. The locking block 205 is set in a position close to the nozzle 202 and matches the groove 204. These grooves provide a track for the sliding of the nozzles 203. Each nozzle 203 has a locking block 205 on its outer surface. These locking blocks match the sliding groove 204 on the nozzle head 202, ensuring the stability and accuracy of the nozzle 203 during sliding. Multiple nozzles 203 are positioned corresponding to multiple through holes 101, and multiple nozzles 203 extend out of the outer casing 100 through the through holes 101. When the nozzles 203 slide to the desired position on the nozzle head 202, they will extend out of the outer casing 100 through the corresponding through holes 101. At this time, the sealing ring 102 fits tightly against the outer wall of the nozzle 203, forming an effective seal to prevent liquid leakage from the gap between the nozzle 203 and the outer casing 100. When liquid enters the nozzle head 202 through the water inlet pipe 201, it will be sprayed out through the nozzles 203, realizing the spraying function. Since the nozzles 203 can slide and adjust their position on the nozzle head 202, the spray range and angle can be adjusted according to actual needs.
[0035] In some embodiments, the outlet of the nozzle 203 gradually approaches the nozzle along the direction of water spraying. The nozzle 203 is a duckbill-shaped flat nozzle 203. This design makes the sprayed water flow more concentrated, increasing the spray pressure and range, and is suitable for occasions requiring a large coverage area or long-distance spraying. In addition, the duckbill-shaped design also helps to reduce the diffusion of water mist, making the spraying more precise.
[0036] In some embodiments, a synchronous connecting chain 206 is provided on the outer wall of the plurality of nozzles 203 and on the portion extending out of the nozzle head 202 within the housing 100. The synchronous connecting chain 206 is used to connect the plurality of nozzles 203 to ensure that they move synchronously during sliding. This design allows the user to easily adjust the position of all nozzles 203 without having to operate each nozzle individually.
[0037] In some embodiments, the nozzle 202 has a tapered guide section with a taper angle of 15°-25° inside. The tapered guide section helps guide the liquid to flow more smoothly into the nozzle 203, improving spraying efficiency. The selection of the taper angle allows the liquid to form a suitable flow rate and pressure inside the nozzle 202, ensuring the consistency and stability of the spraying effect.
[0038] In some embodiments, the synchronous connecting chain 206 is an elastic material chain. The synchronous connecting chain 206 is made of elastic material, has a certain degree of flexibility and durability, can adapt to outer shells 100 of different shapes and sizes, and ensures the stability and reliability of nozzle 203 during movement.
[0039] In some embodiments, the bottom of the outer casing 100 is slidably connected to the water inlet pipe 201, which allows the nozzle 203 to be adjusted in angle by raising or lowering the outer casing 100.
[0040] In some embodiments, the inner edge of the rubber sealing ring 102 is provided with a protrusion 104 that engages with the anti-leakage threaded groove 103, which is designed to achieve better sealing performance.
[0041] In some embodiments, a rotatable adjustment mechanism is provided at the connection between the nozzle 202 and the water inlet pipe 201. The adjustment mechanism includes an axial positioning toothed disc and a matching operating knob. By rotating the operating knob, the axial positioning toothed disc can be driven to rotate, thereby causing the nozzle 202 to rotate relative to the water inlet pipe 201, thereby realizing the adjustment of the spray angle.
[0042] In some embodiments, the outer surface of the housing 100 is provided with an angle scale marking ring, which is coaxially aligned with the rotation reference plane of the nozzle 202. Users can intuitively understand the rotation angle of the nozzle 202 according to the scale on the angle scale marking ring, thereby controlling the spraying range more accurately.
[0043] In some embodiments, the inner surface of the nozzle 203 is provided with a spiral guide pattern. This spiral guide pattern design can guide the water flow to form a rotating flow in the inner cavity of the nozzle, further increasing the spray pressure and range.
[0044] Working Principle: A hollow cylindrical connecting pipe 200 is installed inside the cavity of the outer casing 100, with its inlet end connected to an external water supply system. When water flows through the inlet pipe 201 into the nozzle 202 chamber, the fluid pressure pushes multiple independent nozzles 203 to move synchronously radially along the arc-shaped trajectory of the slide groove 204. The retaining block 205 on the outer wall of the nozzle 203 and the nozzle slide groove 204 form a sliding pair, ensuring axial stability of the nozzle during pressure extension. The rubber sealing ring 102 maintains elastic contact throughout the nozzle extension and retraction process, forming a dynamic sealing interface with the nozzle outer wall through its annular lip. The end of each nozzle 203 passes through a corresponding through hole 101 to form an independent spray channel. Its extension length can be steplessly controlled by adjusting the inlet water pressure, thereby changing the spray angle and coverage area. This mechanical seal structure effectively prevents fluid leakage from the cavity while ensuring multi-directional adjustment functionality.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
