Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology, specifically relating to a differential force rotary nozzle. Background Technology

[0002] A differential force rotary sprinkler head is an irrigation or spraying device that uses the pressure or momentum difference generated by the water flow itself to drive the sprinkler head to rotate automatically. It does not require an external motor, gears, or complex transmission mechanism, and its structure is relatively simple and reliable. As long as the water flow is continuously supplied, this pressure or momentum difference will continue to exist, thereby driving the sprinkler head to rotate continuously. Most existing rotary sprinkler heads are assembled into a one-piece structure using special tooling during production. If a single part is damaged, the entire sprinkler head needs to be scrapped, resulting in high production and usage costs. At the same time, the location of the water outlet that provides the rotational power is relatively limited, and it is impossible to adjust the sprinkler head's own rotation speed when the water pressure is constant. Therefore, it is necessary to develop a differential force rotary sprinkler head. Utility Model Content

[0003] The purpose of this utility model is to provide a differential force rotary nozzle with a simple structure and reasonable design in order to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A differential force rotary nozzle includes a diverter pipe, a rotating mechanism at the bottom of the diverter pipe, connecting platforms symmetrically arranged on the diverter pipe, a water spray pipe mounted on the connecting platforms, a water outlet on the water spray pipe, a diverter frame connected to the water spray pipe by threads, a water divider needle on the diverter frame, and a rotation force adjustment mechanism on the water spray pipe.

[0006] As a further optimization of this utility model, the rotation force adjustment mechanism includes a rotating sleeve that slides on the water spray pipe, a sealing ring is provided at the connection between the rotating sleeve and the water spray pipe, a flow groove is provided on the water spray pipe, the water spray pipe is connected to the rotating sleeve through the flow groove, and a side outlet is provided on the rotating sleeve.

[0007] As a further optimization of this utility model, a support platform is fixedly connected to the water spray pipe, and a guide post is slidably connected in the through hole opened on the support platform. A support spring is provided on the guide post, and the support spring is located in the through hole opened on the support platform. The guide post is fixed on the locking sleeve, the locking sleeve is sleeved on the water spray pipe, and the locking sleeve is attached to the rotating sleeve.

[0008] As a further optimization of this utility model, the locking sleeve is provided with locking protrusions evenly distributed, the locking protrusions are sleeved in the locking grooves, and the locking grooves are evenly distributed on the rotating sleeve.

[0009] As a further optimization of this utility model, the rotating mechanism includes a rotating sleeve threadedly connected to the bottom of the diverter pipe, and an mounting sleeve is rotatably fitted onto the bottom of the rotating sleeve, with a connector provided at the bottom of the mounting sleeve.

[0010] As a further optimization of this utility model, the top of the mounting sleeve is connected to a fixing sleeve by a thread, and the fixing sleeve is rotatably connected to the rotating sleeve.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, a rotating mechanism rotates and supports the diverter pipe. A rotating sleeve fitted onto the spray pipe connects to the spray pipe through a flow groove. Water from the spray pipe passes through the flow groove and enters the rotating sleeve, then sprays out through a side outlet on the rotating sleeve, providing rotational power for the spraying section composed of the diverter pipe and the spray pipe. The rotating mechanism and the spray pipe are both threaded onto the diverter pipe, forming an assembled nozzle structure. Some parts can be replaced independently. The diverter pipe, spray pipe, and rotating mechanism are all made of nylon material, which is lighter and less prone to rust, reducing manufacturing and usage costs. During the spraying process, the water flow is divided by the water-dividing needle on the diverter frame, improving the atomization effect during spraying.

[0013] 2. In this utility model, after the rotating sleeve is fitted onto the water spray pipe, a diverter is installed to limit the rotation of the rotating sleeve, allowing it to rotate on the water spray pipe. At the same time, a guide post slides the locking sleeve onto the support platform. A support spring provides elasticity to press the locking sleeve onto the rotating sleeve. The locking protrusion and locking groove cooperate to prevent the rotating sleeve from rotating. Pushing the locking sleeve towards the support platform allows the locking sleeve to disengage from the rotating sleeve, facilitating the adjustment of the spray angle of the water outlet on the upper side of the rotating sleeve. The rotational torque of the nozzle can be adjusted without changing the parts, thereby achieving the effect of adjusting the nozzle speed. Attached Figure Description

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example

[0021] Please see Figures 1-4 A differential force rotary nozzle includes a diverter pipe 1, a rotating mechanism 2 at the bottom of the diverter pipe 1, and connecting platforms 3 symmetrically arranged on the diverter pipe 1. The connecting platforms 3 on the diverter pipe 1 form a Y-shaped water flow delivery structure. The water flow entering from the bottom of the diverter pipe 1 is evenly distributed to the connecting platforms 3 on both sides. A spray pipe 4 is connected to the connecting platform 3 by a threaded connection. The spray pipe 4 is provided with a hexagonal protrusion for easy tightening with a wrench. A water outlet 5 is provided on the spray pipe 4 to concentrate the water flow and make the water flow spray out at high speed. A diverter frame 6 is connected to the spray pipe 4 by a thread. A water dividing needle 7 is provided on the diverter frame 6. The water flow sprayed out at high speed from the water outlet 5 will first hit the water dividing needle 7 to improve the atomization effect when spraying water. A rotation force adjustment mechanism 8 is provided on the spray pipe 4 to adjust the rotation speed of the nozzle while keeping the water pressure constant.

[0022] The rotation force adjustment mechanism 8 includes a rotating sleeve 81 that slides on the water spray pipe 4. A sealing ring 82 is provided at the connection between the rotating sleeve 81 and the water spray pipe 4 to improve the sealing between the rotating sleeve 81 and the water spray pipe 4. A flow groove 83 is provided on the water spray pipe 4, which connects to the rotating sleeve 81. A side outlet 84 is provided on the rotating sleeve 81. The water flowing into the water spray pipe 4 flows through the flow groove 83 into the space between the rotating sleeve 81 and the outer wall of the water spray pipe 4, and finally sprays out from the side outlet 84. The spray direction does not pass through the rotation axis of the diverter pipe 1, thereby generating rotational power for the nozzle. A support platform 85 is fixedly connected to the water spray pipe 4. A guide post 86 is slidably connected in a through hole on the support platform 85. A support spring 87 is provided on the support 86, and the support spring 87 is located in the through hole opened on the support platform 85. The guide post 86 is fixed on the locking sleeve 88. The guide post 86 is used to limit the movement of the locking sleeve 88. The locking sleeve 88 is sleeved on the water spray pipe 4 and fits against the rotating sleeve 81. Locking protrusions 89 are evenly arranged in the locking sleeve 88. The locking protrusions 89 are sleeved in the locking grooves 90. The locking grooves 90 are evenly opened on the rotating sleeve 81. The locking protrusions 89 and the locking grooves 90 are evenly distributed on the locking sleeve 88 and the rotating sleeve 81 in a circumferential manner. There are twelve sets of locking protrusions 89 and locking grooves 90. When there is no external force interference, the locking protrusions 89 and locking grooves 90 are sleeved on each other to prevent the locking sleeve 88 from rotating relative to each other.

[0023] The rotating mechanism 2 includes a rotating sleeve 21 threadedly connected to the bottom of the diversion pipe 1. A mounting sleeve 22 is rotatably sleeved at the bottom of the rotating sleeve 21. A connector 23 is provided at the bottom of the mounting sleeve 22. A fixed sleeve 24 is threadedly connected to the top of the mounting sleeve 22. The fixed sleeve 24 is rotatably connected to the rotating sleeve 21. The rotating sleeve 21 serves as the rotating base of the diversion pipe 1 and is rotatably connected to the top of the mounting sleeve 22 via the fixed sleeve 24. The connector 23 at the bottom of the mounting sleeve 22 is used to connect to the water outlet equipment to receive the water flow.

[0024] It should be noted that, in use, this differential rotary nozzle is first connected to the water outlet device via the connector 23. The water flow provided by the water outlet device passes through the mounting sleeve 22 and the rotating sleeve 21 into the diversion pipe 1, and is guided to the water outlets 5 on both sides by the symmetrically distributed spray pipes 4. The water then passes through the water outlets 5 and impacts the water distribution needles 7 to achieve atomization. During the spraying process, the water flow in the spray pipes 4 passes through the flow groove 83 and enters the rotating sleeve 21, and is sprayed out through the side outlets 84 opened on the rotating sleeve 21, providing rotational power for the spraying part composed of the diversion pipe 1 and the spray pipes 4, driving the nozzle to rotate and spray water. When it is necessary to adjust the nozzle speed, the locking sleeve 88 is pushed towards the support platform 85, which can disengage the locking sleeve 88 from the rotating sleeve 81. Then, the spray angle of the side outlets 84 on the rotating sleeve 81 is adjusted by rotating the rotating sleeve 81, and the nozzle speed is adjusted while the water pressure remains constant.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
