[0002] The overhead shower is positioned above the user's head. Existing overhead showers can switch between multiple water streams to provide different bathing experiences, but the water spray direction is singular. Changing the water spray direction requires rotating the entire overhead shower, which is inconvenient. Utility Model Content

The rotating body is freely movable within the cavity. The rotating body is equipped with a second water nozzle and a water inlet that communicates with the second water nozzle and the cavity. The lower end of the rotating body extends into the annular limiting groove. The rotating water flow inside the cavity can drive the lower end of the rotating body to revolve within the annular limiting groove, and the second spray nozzle can remain in contact with the first spray nozzle to achieve rotating water spray.

[0005] According to the present invention, a multifunctional top sprayer is provided in which water flows through the filter assembly, is diverted and adjusted by multiple components, and enters the rotating nozzle, which drives the rotating body to rotate, so that the sprayed water produces a rotating effect.

Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. 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.

[0015] 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.

[0016] After the water flows through the filter assembly, it is diverted and adjusted by multiple components before entering the rotating nozzle, which drives the rotating body to rotate, thus creating a rotating effect in the sprayed water.

[0017] 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.

[0018] The following is for reference. Figure 1-7 The implementation method of the shower rod proposed in the embodiments of this utility model will be described in detail.

[0019] Filter assembly 1 has a water inlet at one end and a water outlet at the other end; The filter assembly 1 has a built-in replaceable filter element for easy replacement and reduced clogging. Specifically, the filter assembly 1 has an internal thread at one end for connecting to the water inlet pipe and an external thread at the other end for connecting to the subsequent water outlet assembly, thus achieving easy disassembly and assembly. The water outlet assembly includes a guide plate 2, a water distribution plate 3, an installation plate 4, and a switching plate 6 arranged in sequence. The water flow is filtered by the filter assembly 1 and first enters the guide plate 2. Several water channels in the guide plate 2 divide the water flow into multiple paths, and then flow into the water distribution plate 3. The water distribution plate 3 further subdivides the water flow into multiple water columns. The water columns enter several water outlet columns set in the installation plate 4 and are shaped and sprayed out. The switching plate 6 drives the installation plate 4 to rotate. When in use, the different functions of the shower head can be switched on and off by rotating the 6-way switch. Specifically, by rotating the switch, some water channels can be closed while others can be connected.

[0020] A rotating nozzle is located in the 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 has a first 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 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 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 spray nozzle 5411 can remain in contact with the first spray nozzle 511 to achieve rotating water spray.

[0021] Rotary nozzle 5 is installed in 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 spray nozzle 5411 can remain in contact with the first spray nozzle 511 to achieve rotating water spray.

[0022] 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 the 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.
