[0015] [Example 1] As shown in Figures 1 to 6, the rotating water sprinkler head 01 of the present invention comprises a shell-shaped main body 10, a rotating body 20, and a restricting member 30, of which a hollow chamber 11 is formed inside the main body 10, the rotating body 20 is provided in the hollow chamber 11, one axial end of the main body 10 is defined as a water inlet end 12, the other axial end is defined as a water outlet end 13, and a virtual first limiting axis passing through the water inlet end 12 and the water outlet end 13 along the axial direction of the hollow chamber 11 is defined as a first limiting axis. An axis L1 is defined, and the restricting member 30 is provided at the water inlet end 12 and restricts the rotating body 20 to be positioned in the hollow chamber 11, and annular first and second spaces 112 and 114 are formed in the hollow chamber 11, the first space 112 extends and communicates with the second space 114, the first space 112 surrounds the radial outer periphery of the rotating body 20, and the second space 114 is located between the rotating body 20 and the restricting member 30.

[0016] The main body 10 is formed with a number of abutment parts 14 spaced apart from each other and connected to the water discharge ends 13, and a water discharge passage 15 passes through each of the abutment parts 14 on the side facing the first axis L1. One end of the water discharge passage 15 communicates with the hollow chamber 11 and the other end extends to the water discharge end 13. A number of flow leakage passages 16 are formed between two adjacent abutment parts 14, and each of the flow leakage passages 16 is , each of which connects the discharge path 15 and the first space 112, and each of the flow leakage passages 16 extends to the discharge end 13, and a conical surface 17 is formed in the main body 10 which annularly surrounds the hollow chamber 11, the first axis L1 passes through the circular center of the conical surface 17, and the diameter of the conical surface 17 gradually decreases in the direction from the water inlet end 12 to the discharge end 13 along the first axis L1.

[0017] The rotor 20 is formed with an abutment portion 21 and a cone-shaped portion 22 along its axial direction, of which one end of the abutment portion 21 abuts against each of the abutment portions 14, and the cone-shaped portion 22 is formed at one end adjacent to the rotor 20 and far away from the abutment portion 21, and the radial outer periphery of the cone-shaped portion 22 is conical, and the outer diameter gradually increases from one end approaching the abutment portion 21 of the cone-shaped portion 22 to the other end along the axial direction of the rotor 20, and the cone-shaped portion 22 and the cone surface 17 face each other along the radial direction, and a flow guide passage 23 communicating with the water discharge path 15 is formed through the abutment portion 21, and a flow guide passage 23 passing through the radial center of the flow guide passage 23 is formed through the abutment portion 21. A virtual second axis L2 is defined, and the second axis L2 and the first axis L1 cross each other obliquely, so that the axial direction of the flow guide passage 23 is inclined relative to the axial direction of the hollow chamber 11. Specifically, an included angle θ is formed between the second axis L2 and the first axis L1, and the included angle θ is between 1° and 6°. When the included angle θ illustrated in Example 1 is 2°, a conical flow convergence passage 24 is formed penetrating the inside of the conical portion 22 along the axial direction thereof, connecting the flow guide passage 23 and the second space 114, and the inner diameter of the flow convergence passage 24 gradually increases from one end of the flow convergence passage 24 adjacent to the flow guide passage 23 to the other end.

[0018] A water inlet 32 ​​communicating with the second space 114 is formed through the restricting member 30 in the axial direction, and the inner diameter of the water inlet 32 ​​is equal to or smaller than the inner diameter of the flow convergence passage 24 on the side approaching the front water inlet 32, and it is a better implementation option to make the inner diameter of the water inlet 32 ​​smaller than the inner diameter of the flow convergence passage 24 on the side approaching the front water inlet 32.As the water passes through the water inlet 32 ​​and enters the second space 114, and then branches off and passes through the first space 112 and the flow guide passage 23, the rotation of the rotating body 20 itself is braked and it rotates in a spiral shape based on the first axis L1.

[0019] Water passes through the water inlet 32 ​​and enters the second space 114, and is then diverged to enter the flow convergence passage 24 and the first space 112 that annularly surrounds the rotor 20.

[0020] The water that enters the rotor 20 is guided by the conical flow converging passage 24, thereby increasing the flow rate at which the water flows into the flow converging passage 24 so that the water flow can be concentrated toward the flow guide passage 23.The water is then guided by the flow guide passage 23 to be redirected in a direction along the second axis L2, passes through the flow guide passage 23 and the water discharge path 15, and leaves the rotating sprinkler head 01 to be sprayed towards the outside.

[0021] The water that passes through the first space 112 is guided by the conical surface 17 and flows toward the water outlet end 13 in a concentrated direction radially outward from the rotor 20, and then passes through each of the flow leakage passages 16, leaves the rotating sprinkler head 01, and is sprayed toward the outside.

[0022] The first space 112 annularly surrounds the radial outer periphery of the rotating body 20, and the second space 114 is located between the rotating body 20 and the restricting member 30, so that the radial outer periphery of the rotating body 20 and one end thereof toward the restricting member 30 are not restricted by the collision between the main body 10 and the restricting member 30, and the hollow chamber 11 provides a space in which the rotating body 20 can move.

[0023] In the process of the water flow passing through the first space 112 and flowing toward each of the flow leakage passages 16, the conical surface 17 guides the direction of the water flow, and the water flow acts obliquely on the radial outside of the rotor 20. In accordance with the spatial configuration in which the axial direction of the flow guide passage 23 is inclined relative to the axial direction of the hollow chamber 11, in the process of the water flow with an increased flow rate passing through the flow guide passage 23, the water flow acts on the rotor 20 and forms a biasing force on the part that defines and surrounds the flow guide passage 23 in an annular shape. As a result, the force acting obliquely on the radial outside of the rotor 20 and the force formed inside the flow guide passage 23 and acting biasingly on the rotor 20 can rotate the rotor 20 itself, and at the same time, the rotor 20 rotates in a spiral shape based on the first axis L1, forming a motion similar to an orbital motion.

[0024] The axial direction of the flow guide passage 23 is constantly changing in accordance with the spiral rotational motion of the rotor 20, so that the water flow that passes through the flow guide passage 23 and can be sprayed outward is gradually diffused toward the circumferential side as it travels toward the front end of the rotating type sprinkler head 01 along a path that resembles a spiral.

[0025] The degree of taper of the radial circumference of the conical portion 22 is greater than the degree of taper of the conical surface 17 and the degree of taper of the flow converging passages 24 is greater than the degree of taper of the conical surface 17 .

[0026] The main body 10 is formed with several surrounding blocks 18 that annularly surround the radial outside of the abutment portion 21, and each of the flow leakage passages 16 extends between two adjacent surrounding blocks 18, and the first space 112 extends between each of the surrounding blocks 18 and the abutment portion 21 and is connected to each of the flow leakage passages 16.

[0027] When the rotating body 20 rotates in a spiral shape, each of the surrounding blocks 18 that surround the abutment portion 21 in an annular shape is able to limit the deflection angle relative to the first axis L1 in the axial direction of the rotating body 20, and the flow guide passage 23 limits the range extended and projected toward the rotating body 20 along the first axis L1 in the water discharge path 15 at the end portion of the abutment portion 21, allowing the water flow leaving the flow guide passage 23 to complete entering the water discharge path 15, thereby preventing a portion of the water flow leaving the flow guide passage 23 from colliding with the abutment portion 14, which would affect the efficiency of water being sprayed toward the outside.

[0028] Each of the surrounding blocks 18 is connected to one side of each of the abutment portions 14 in a direction facing the hollow chamber 11 .

[0029] FIG. 7 illustrates a type of fountain device 02 having the swiveling water sprinkler jet head 01. The fountain device 02 is a type of fountain gun. The fountain device 02 has a housing 40 and one of the swiveling water sprinkler jet heads 01. The swiveling water sprinkler jet head 01 is provided inside the housing 40, and the water discharge path 15 is connected to the outside of the housing 40. A flow path 42 is formed inside the housing 40. One end of the flow path 42 is used to connect to a water supply pipe 92, and the other end of the flow path 42 is connected to the water inlet 32. The water supply pipe 92 is an external pipeline that supplies water to the fountain device 02.

[0030] Figure 8 shows an example of another type of water spray device 03 having the swirling water sprinkler spray head 01. The water spray device 03 is a type of elongated water spray device, and a specific example of this may be a type of nozzle. The water spray device 03 has an elongated housing 50 and one of the swirling water sprinkler spray heads 01, of which the swirling water sprinkler spray head 01 is provided inside the housing 50, and the water discharge path 15 is connected to the outside of the housing 50. A flow path 52 is formed inside the housing 50, and one end of the flow path 52 is used to connect to a water supply pipe 92, and the other end of the flow path 52 is connected to the water inlet 32.

[0031] [Example 2] As shown in Figures 9 and 10, the configuration different from Example 1 will be mainly described. In Example 2 of the rotating type sprinkler spray head 01, when the included angle θ formed between the second axis L2 and the first axis L1 is 5°, when the rotating body 20 rotates in a spiral shape, the deflection angle relative to the first axis L1 in the axial direction of the rotating body 20 can be increased.

[0032] A communication path 25 is formed on the side of the rotor 20, connecting the first space 112 and the flow guide passage 23. The water flow that has passed through the first space 112 is branched, and a portion of the water flows through the communication path 25 and enters the flow guide passage 23. In the process of being turned according to the second axis L2 and flowing toward the water discharge path 15, a force is generated that increases the deflection angle with respect to the rotor 20. As a result, when the rotor 20 rotates in a spiral shape, the deflection angle relative to the first axis L1 in the axial direction of the rotor 20 is increased, and a portion of the water flow that has passed through the first space 112 is drawn into the flow guide passage 23, thereby increasing the amount of water that passes through the flow guide passage 23 and is sprayed outward, and proceeds in a path that is close to a spiral shape.

[0033] [Example 3] As shown in Figure 11, the configuration different from Example 1 will be mainly described. In Example 3 of the rotating type sprinkler head 01, the inner diameter of the water inlet 32 ​​is larger than the inner diameter of the flow convergence passage 24 on the side approaching the front water inlet 32.

[0034] [Example 4] As shown in FIG. 12, the configuration of the fourth embodiment of the swiveling type sprinkling head 01 in the fourth embodiment, which is different from the first embodiment, is as follows. In the fourth embodiment of the swiveling type sprinkling head 01 in the fourth embodiment, the restricting member 30 is selectively fitted and joined to the main body 10. [Explanation of symbols]
