Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0017] When the water flow of this utility model is in use, the external components face the user, allowing the user to easily switch water paths by rotating the knob. The rotating nozzle provides a cone-shaped impact water flow, making the bathing experience more diverse.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] The following is for reference. Figure 1-9 The implementation method of the shower rod proposed in the embodiments of this utility model will be described in detail.

[0020] The water flow distribution component 1 includes a movable connecting element 11, a guiding element 12, and a distribution element 13. The movable connecting element 11 is bendable and guides the incoming water flow into the guiding element 12. Specifically, the movable connecting element 11 has a ball joint with an internal channel. The ball joint moves within the design range without blocking the internal channel, thereby enabling the adjustment of the position of the subsequent structure.

[0021] The guide element 12 connects the connecting element 11 and the distribution element 13, and the water flows into the distribution element 13 through the guide element 12. Specifically, the distribution element 13 can be composed of two upper and lower structures. The upper piece has several through holes, and the lower piece is divided into several areas. Each area has a water outlet through hole that communicates with the receiving cavity. Each area also corresponds to a through hole in the upper piece for water to flow in.

[0022] The rotating component 2 includes a rotating element 21 and a knob 22. The rotating element 21 is driven to rotate by the knob 22, which connects or blocks the water flow of the guide element 12. Specifically, the rotating element 21 has at least one through hole. The through hole is rotated by the knob 22, so that the through hole can connect the through hole of the upper plate of the aforementioned guide element 12 with the movable connecting element 11, so that the water flow can enter the distribution element 13. Conversely, it can also block this passage by rotating, so that the through hole of the upper plate no longer receives water flow. By connecting different through holes of the upper plate through the through hole, the water flow is introduced into different areas divided by the lower plate, and finally flows out from different through holes of the lower plate.

[0023] The water outlet component 3, combined with the distribution element 13, forms a receiving cavity. The water outlet component 3 is provided with several water outlet holes 31. The receiving cavity is divided into different areas by the lower plate, so that the water outlet holes 31 can selectively outlet water.

[0024] The outer element 4 is fitted onto the outside of the water outlet assembly 3, and the knob 22 extends out of the outer element 4. The knob 22 is located in the center of the outer element 4, which allows the user to operate it conveniently. Compared with some existing lever settings, the knob can reduce the operator's operating height.

[0025] A rotating nozzle 5 is provided on the dispensing element 13 and has a cavity 53. The top of the cavity 53 is tapered and has a first water spray nozzle 511. The bottom of the cavity 53 has an annular limiting groove 521. The annular limiting groove 521 is coaxially arranged with the first water spray nozzle 511. The cavity 53 has an inlet channel 522 and a drain channel 523 at the annular limiting groove 521. Water flows through the inlet channel 522 into the annular limiting groove 521 and is discharged from the drain channel 523, thus forming a rotating water flow inside the cavity 53. Rotating body 54 is freely movable inside cavity 53. Rotating body 54 is provided with second water nozzle 5411 and water inlet hole 5421 communicating with second water nozzle 5411 and cavity 53. The lower end of rotating body 54 extends into annular limiting groove 521. The rotating water flow inside the cavity 53 can drive the lower end of the rotating body 54 to revolve within the annular limiting groove 521, and the second water nozzle 5411 can remain in contact with the first water nozzle 511 to realize the rotating water spray assembly element 3, and fix the water distribution element 2 to the connecting element 1. A rotating nozzle 5 is disposed in a cavity formed by the guide plate 2, the water distribution plate 3, and the mounting plate 4. The top of the cavity 53 is conical and narrowed and is provided with a first water spray nozzle 511. The bottom of the cavity 53 is provided with an annular limiting groove 521. The annular limiting groove 521 is coaxially arranged with the first water spray nozzle 511. The cavity 53 is provided with an inlet channel 522 and a drain channel 523 at the annular limiting groove 521. Water flows through the inlet channel 522 into the annular limiting groove 521 and is discharged from the drain channel 523 to form a rotating water flow in the cavity 53. Rotating body 54 is freely movable inside cavity 53. Rotating body 54 is provided with second water nozzle 5411 and water inlet hole 5421 communicating with second water nozzle 5411 and cavity 53. The lower end of rotating body 54 extends into annular limiting groove 521. The rotating water flow inside the cavity 53 can drive the lower end of the rotating body 54 to revolve within the annular limiting groove 521, and the second water nozzle 5411 can remain in contact with the first water nozzle 511 to achieve rotating water spraying.

[0026] Rotary nozzle 5 is installed on housing 1 to rotate and spray water from water chamber 4. The rotating nozzle 5 includes: The cavity 53 has a tapered top with a first water nozzle 511 and an annular limiting groove 521 at the bottom. The annular limiting groove 521 is coaxially arranged with the first water nozzle 511. The cavity 53 has an inlet channel 522 and a drain channel 523 at the annular limiting groove 521. Water flows through the inlet channel 522 into the annular limiting groove 521 and is discharged from the drain channel 523 to form a rotating water flow inside the cavity 53. Rotating body 54 is freely movable inside cavity 53. Rotating body 54 is provided with second water nozzle 5411 and water inlet hole 5421 communicating with second water nozzle 5411 and cavity 53. The lower end of rotating body 54 extends into annular limiting groove 521. The rotating water flow inside the cavity 53 can drive the lower end of the rotating body 54 to revolve within the annular limiting groove 521, and the second water nozzle 5411 can remain in contact with the first water nozzle 511 to achieve rotating water spraying.

[0027] In other words, when switch 3 is turned on, external water enters the water-containing cavity 4 of the housing 1 through the water inlet pipe 2. The water in the cavity 4 is then injected into the cavity 53 through the water inlet channel 522 of the rotating nozzle 5. After entering, the water flows along the annular limiting groove 521 to the drain channel 523, creating a rotating water flow within the cavity 53. This rotating water flow directly acts on the rotating body 54, providing rotational driving force for its rotation. The top of the cavity 53 is conical and narrowed. The rotating body 54 is located within the cavity 53. When filled with water, the rotating body 54 tends to move toward the top of the cavity 53, so that the second water nozzle 5411 remains in contact with the first water nozzle 511 at the top of the cavity 53. At the same time, the annular limiting groove 521 can limit the lower end of the rotating body 54, so that the lower end of the rotating body 54 is restricted to rotate within the annular limiting groove 521. In this way, the water in the cavity 53 is sprayed out through the water inlet 5421 of the rotating body 54 by rotating out of the second water nozzle 5411. The cavity 53 is provided with a central column 524 that protrudes from its bottom wall toward the top of the cavity 53. An annular limiting groove 521 is formed between the outer peripheral wall of the central column 524 and the inner peripheral wall of the cavity 53. The cavity 53 can be formed by connecting the upper shell 51 and the lower shell 52 to facilitate the installation of the rotating body 54. The first water nozzle 511 is provided on the upper shell 51, and the annular limiting groove 521, the water inlet channel 522 and the drainage channel 523 are provided on the lower shell 52. The water inlet hole 5421 can be provided on the side or bottom of the rotating body 54. The diameter of the outer wall of the second water nozzle 5411 can be larger than the diameter of the first water nozzle 511. Thus, external water is introduced into the water-receiving cavity 4 of the housing 1 through the water inlet pipe 2. The water flow in the water-receiving cavity 4 enters the rotating nozzle 5 to form a rotating water flow, which provides rotational driving force for the rotating body 54 inside the cavity 53. The rotating body 54 rotates and sprays water out in a rotating manner. This shower rod has a simple structure, a wide spray range, and can optimize the user's showering experience.

[0028] Optionally, the rotating body 54 has a structure that is larger in the middle and smaller at both ends in the axial direction. Understandably, the top of the rotating body 54 is used to mate with the tapered constriction at the top of the cavity 53, the middle part of the rotating body 54 is used to mate with the inner wall of the middle part of the cavity 53, and the bottom of the rotating body 54 is used to mate with the annular limiting groove 521. When the rotating body 54 revolves, the top of the rotating body 54, in mate with the tapered constriction, forms a fulcrum-like function, and the middle part of the rotating body 54, in contact with the inner wall of the cavity 53, provides a supporting abutment, allowing the rotating body 54 to rotate simultaneously with its own rotation. This reduces the rotational resistance of the rotating body 54 and improves the smoothness of its rotation. The bottom of the rotating body 54, in mate with the annular limiting groove 521, restricts the lower end of the rotating body 54 to rotate along a designated path. The cavity 53 and the rotating body 54 are arranged to match the contour of their revolution. The bottom of the rotating body 54 is provided with a limiting post 5423, which is coaxially arranged with the second water nozzle 5411.

[0029] Furthermore, there are multiple water inlet holes 5421, which are located at the bottom of the large central section of the rotating body 54 and spaced apart around the axis of the rotating body 54. Understandably, the large central section of the rotating body 54 provides space for multiple water inlet holes 5421. Distributing these holes around the axis allows the rotating water flow within the annular limiting groove 521 to enter each water inlet hole 5421 more evenly, avoiding problems such as excessive local pressure or uneven center of gravity distribution caused by concentrated water flow in a single water inlet hole 5421. This reduces jamming caused by uneven force during rotation of the rotating body 54, ensuring stable rotation speed and uniform water flow during showering. Simultaneously, the multiple water inlet hole design improves water intake efficiency, prevents interruptions in water flow due to blockage of a single hole, and ensures the continuity of the shower process.

[0030] Furthermore, the isolation zone between adjacent water inlets 5421 forms a water-blocking section 5422. Understandably, the water-blocking section 5422 serves as the outer wall of the water inlet 5421, and also increases the force of the rotating water flow on the rotating body 54, so that the rotating water flow can more easily drive the rotating body 54 to rotate. The multiple water-blocking sections 5422 are arranged radially.

[0031] Optionally, the outer peripheral wall of the second nozzle 5411 is constricted along the water flow direction. Understandably, by constricting the outer peripheral wall of the second nozzle 5411, the second nozzle 5411 can fit more closely to the inner wall of the first nozzle 511, reducing the obstruction of the first nozzle 511 on the second nozzle 5411, increasing the rotation angle of the second nozzle 5411, and achieving a larger range of rotational spray. Specifically, the cavity 53 extends downwards from the first nozzle 511 with an annular protrusion 512. The annular protrusion 512 has a conical constriction, and the top of the conical constriction is provided with the second nozzle 5411. The rotating body 54 has a groove 5412 at the lower edge of the annular protrusion 512. The groove 5412 and the lower edge of the annular protrusion 512 can make way for each other during the rotation of the rotating body 54, allowing the rotating body 54 to achieve a larger range of rotation.

[0032] Optionally, both the inlet channel 522 and the outlet channel 523 are tangentially connected to the annular limiting groove 521. Understandably, the inlet channel 522 allows water to flow in tangentially to the annular limiting groove 521, minimizing the impact force on the inner and outer walls of the annular limiting groove 521. This allows water to flow smoothly into the annular limiting groove 521 and then smoothly out of the outlet channel 523 tangentially. This generates a stable rotating water flow without additional structural guidance, resulting in a simple and reliable structure. The inlet channel 522 and the outlet channel 523 can be symmetrically distributed with a 90° rotation.

[0033] Furthermore, the rotating body 54 includes a first part 541 and a second part 542 connected to the first part 541. A second water nozzle 5411 is disposed in the first part 541, and a water inlet 5421 is disposed in the second part 542. Understandably, by separating the rotating body 54 into two parts, the processing difficulty of the rotating body 54 can be greatly reduced, thereby lowering manufacturing costs. Water flows into the first part 541 through multiple water inlets 5421, then converges in the second part 542 and is ejected from the second water nozzle 5411. The first part 541 and the second part 542 can be connected by a sleeve connection or by ultrasonic welding.
