Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a shower head. Background Technology

[0002] In the modern bathroom industry, the showerhead, as a core sanitary ware, directly impacts the user experience through its water flow pattern and overall feel. Currently, most mainstream showerheads on the market use a fixed spray nozzle design, resulting in a relatively limited water flow direction and coverage. Especially for showerheads with top-mounted water flow, existing products are mostly direct-spray or fixed-angle sprays, failing to achieve dynamic rotation and coverage of the water flow at the top. This leads to blind spots in areas such as the back and shoulders during showering, making it difficult to meet the user's need for even spraying of the entire body.

[0003] Some showerheads with rotating water outlets either only rotate the water flow on the side or require manual adjustment of the rotation angle, failing to achieve automatic continuous rotation of the water flow from the top. This makes operation cumbersome and easily disrupts the shower's continuity. In addition, a few top rotating water outlet designs rely on multiple sets of transmission components, resulting in complex structures, high assembly difficulty, high failure rates, and high production costs, making it difficult to achieve widespread adoption.

[0004] In summary, existing showerheads have significant technical shortcomings in terms of the automatic rotating spray function at the top. There is an urgent need for a showerhead design that is simple in structure, can stably achieve the rotating spray of water from the top, and takes into account both practicality and economy, in order to fill the market gap and optimize the user's shower comfort.

Detailed Implementation

[0017] 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.

[0018] 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.

[0019] 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.

[0020] The following is for reference. Figure 1-7 The implementation method of the shower head proposed in the embodiments of this utility model will be described in detail.

[0021] The shower head according to an embodiment of the present utility model includes: Handle 1, handle 1 is provided with a first water flow channel 11; Shower head 2, shower head 2 is connected to handle 1, and shower head 2 is provided with a second water flow channel 211 that communicates with the first water flow channel 11; Rotary nozzle 3 is installed inside shower head 2 and communicates with the second water flow channel 211 to spray water from the top of shower head 2 in a rotating manner. The rotating nozzle 3 includes: The cavity 33 has a tapered top with a first water nozzle 311 and an annular limiting groove 321 at the bottom. The annular limiting groove 321 is coaxially arranged with the first water nozzle 311. The cavity 33 has a first channel 322 and a second channel 323 at the annular limiting groove 321. Water flows into the annular limiting groove 321 from the first channel 322 and / or the second channel 323, forming a rotating water flow. Rotating body 34 is freely movable inside cavity 33. Rotating body 34 is provided with second water nozzle 3411 and water inlet hole communicating with second water nozzle 3411 and cavity 33. The lower end of rotating body 34 extends into annular limiting groove 321. The rotating water flow inside the cavity 33 can drive the lower end of the rotating body 34 to revolve within the annular limiting groove 321, and the second water nozzle 3411 can remain in contact with the first water nozzle 311 to rotate and spray water.

[0022] In other words, external water enters the second water flow channel 211 of the shower head 2 from the first water flow channel 11 of the handle 1. The second water flow channel 211 can supply water to the rotating nozzle 3. The water flow enters the cavity 33 from the first channel 322 and / or the second channel 323 of the rotating nozzle 3. After entering, the water flow will flow along the annular limiting groove 321, so that a rotating water flow is formed in the cavity 33. The rotating water flow can directly act on the rotating body 34 to provide rotational driving force for the rotation of the rotating body 34. The top of the cavity 33 is tapered. As the rotating body 34 is filled with water in the cavity 33, it tends to move towards the top of the cavity 33, so that the second water nozzle 3411 remains in contact with the first water nozzle 311 at the top of the cavity 33. At the same time, the annular limiting groove 321 can limit the lower end of the rotating body 34, so that the lower end of the rotating body 34 is restricted to rotate within the annular limiting groove 321. Thus, the water in the cavity 33 is sprayed out through the water inlet 3421 of the rotating body 34 from the second water nozzle 3411. The cavity 33 is provided with a central column 324 protruding from its bottom wall toward the top of the cavity 33. An annular limiting groove 321 is formed between the outer peripheral wall of the central column 324 and the inner peripheral wall of the cavity 33. The cavity 33 can be formed by connecting the upper shell 31 and the lower shell 32 to facilitate the installation of the rotating body 34. The first water nozzle 311 is provided on the upper shell 31, and the annular limiting groove 321, the first channel 322 and the second channel 323 are provided on the lower shell 32. The water inlet 3421 can be provided on the side or bottom of the rotating body 34. The diameter of the outer wall of the second water nozzle 3411 can be larger than the diameter of the first water nozzle 311. The handle 1 and the shower head 2 can adopt existing structures. For example, the shower head 2 can switch the water outlet state of the first water outlet on the water outlet panel 26 by rotation. The handle 1 or the shower head 2 is provided with a button 213 to control the water output. The water output control structure can adopt existing structures. Thus, external water is supplied to the shower head 2 via the handle 1. The water flow in the shower head 2 enters the rotating nozzle 3, forming a rotating water flow. This provides rotational driving force for the rotating body 34 within the cavity 33. The rotating body 34 rotates and sprays water out in a rotating manner. This produces a rotating, plate-like water spray, i.e., a cone-shaped water spray, which is aesthetically pleasing, provides a comfortable impact, and has a massage effect. This shower head has a simple structure and can achieve rotating water output, optimizing the user's showering experience.

[0023] Optionally, the rotating body 34 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 34 is used to mate with the tapered constriction at the top of the cavity 33, the middle part of the rotating body 34 is used to mate with the inner wall of the middle part of the cavity 33, and the bottom of the rotating body 34 is used to mate with the annular limiting groove 321. When the rotating body 34 revolves, the top of the rotating body 34, in mate with the tapered constriction, acts as a kind of pivot point, and the middle part of the rotating body 34, in contact with the inner wall of the cavity 33, provides a supporting abutment. This allows the rotating body 34 to rotate simultaneously with its revolution, thus reducing the rotational resistance of the rotating body 34 and improving the smoothness of its rotation. The bottom of the rotating body 34, in mate with the annular limiting groove 321, restricts the lower end of the rotating body 34 to rotate along a designated path. The cavity 33 and the rotating body 34 are arranged to match the contour of their revolution. The bottom of the rotating body 34 is provided with a limiting post 3423, which is coaxial with the second water nozzle 3411.

[0024] Furthermore, there are multiple water inlet holes 3421, which are located at the bottom of the large central section of the rotating body 34 and spaced apart around the axis of the rotating body 34. Understandably, the large central section of the rotating body 34 provides space for multiple water inlet holes 3421. Distributing these holes around the axis allows the rotating water flow within the annular limiting groove 321 to enter each water inlet hole 3421 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 3421. This reduces jamming caused by uneven force during rotation of the rotating body 34, 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 3421 forms a water-blocking section 3422. Understandably, the water-blocking section 3422 serves as the outer wall of the water inlet 3421, and also increases the force of the rotating water flow on the rotating body 34, allowing the rotating water flow to more easily drive the rotating body 34 to rotate. The multiple water-blocking sections 3422 are arranged radially.

[0026] Optionally, the outer peripheral wall of the second nozzle 3411 is constricted along the water flow direction. Understandably, by constricting the outer peripheral wall of the second nozzle 3411, the second nozzle 3411 can fit more closely to the inner wall of the first nozzle 311, reducing the obstruction of the first nozzle 311 by the second nozzle 3411, increasing the rotation angle of the second nozzle 3411, and achieving a larger range of rotational spray. Specifically, the cavity 33 extends downwards from the first nozzle 311 with an annular protrusion 312. The annular protrusion 312 has a conical constriction, and the top of the conical constriction houses the second nozzle 3411. The rotating body 34 has a groove 3412 for installing a sealing ring, which abuts against the lower end face of the annular protrusion 312 to prevent water from entering through the gap between the conical constriction and the rotating body 34.

[0027] Optionally, both the first channel 322 and the second channel 323 are tangentially connected to the annular limiting groove 321. Understandably, the first channel 322, with water flowing into it tangentially to the annular limiting groove 321, minimizes the impact force on the inner and outer walls of the annular limiting groove 321, allowing water to flow smoothly into the annular limiting groove 321 and quickly form a rotating water flow. This generates a stable rotating water flow without the need for additional structural guidance, resulting in a simple and reliable structure. The first channel 322 and the second channel 323 can be symmetrically distributed with a 180° rotation.

[0028] Furthermore, the rotating body 34 includes a first part 341 and a second part 342 connected to the first part 341. A second water nozzle 3411 is disposed in the first part 341, and a water inlet 3421 is disposed in the second part 342. Understandably, by separating the rotating body 34 into two parts, the processing difficulty of the rotating body 34 can be greatly reduced, thereby lowering manufacturing costs. Water flows into the first part 341 through multiple water inlets 3421, then is collected by the second part 342 and ejected from the second water nozzle 3411. The first part 341 and the second part 342 can be connected by a sleeve connection or by ultrasonic welding.

[0029] Optionally, the second water flow channel 211 is provided with a first water outlet, a second water outlet, and a switch 212. The switch 212 is used to switch the on / off state between the first and second water outlets. The first water outlet and the second spray nozzle are arranged facing the top and side of the shower head 2 respectively, one-to-one. The first channel 322 and / or the second channel 323 connect to the first water outlet, and the second spray nozzle connects to the first water outlet hole of the water outlet panel 26 of the shower head 2. Understandably, by setting the switch 212 to switch the on / off state between the first and second water outlets, the user can select different water flow modes according to their needs: when switched to the first water outlet, water flows into the rotating nozzle 3 to form a rotating water flow, meeting the needs of comfortable showering and massage; when switched to the second water outlet, water flows through the first water outlet hole 261 of the water outlet panel 26 and sprays out, achieving a regular shower. This design enriches the shower head's functions, improves its flexibility of use, and adapts to diverse scenarios.

[0030] Furthermore, the shower head 2 includes a rear cover plate 21, a water distribution plate 22, a sealing cover 23, a first water outlet plate 24, a second water outlet plate 25, and a water outlet panel 26. The rear cover plate 21 is detachably connected to the handle 1, and the rear cover plate 21 and the water outlet panel 26 are rotatably connected to jointly construct an installation cavity. The water distribution plate 22, the sealing cover 23, the first water outlet plate 24, and the second water outlet plate 25 are installed in the installation cavity. Understandably, the rear cover 21 is detachably connected to the handle 1, facilitating the inspection and replacement of internal components; the water distribution plate 22 inside the mounting cavity is responsible for water flow distribution, and the sealing cover 23 ensures the water circuit is sealed to prevent leakage; the first water outlet plate 24 and the second water outlet plate 25 work together to connect different water circuits on the water distribution plate 22 to the water outlet panel 26; the rear cover 21 and the water outlet panel 26 are rotatably connected, making it convenient to adjust the water outlet state of the water outlet panel 26 by rotating the water outlet panel 26, such as switching between the large-diameter and small-diameter first water outlet holes; the coordinated action of each component makes the shower head structure compact and easy to assemble, while improving overall durability and user experience. When the water outlet panel 26 rotates, it can drive the first water outlet plate 24, the second water outlet plate 25 and the sealing cover 23 to rotate synchronously. The water passage hole group on the first water outlet plate 24 is connected to different water channels on the water distribution plate 22, thereby switching the water outlet state of the water outlet panel 26. The top of the outer peripheral wall of the rear cover plate 21 is provided with a mounting hole 214. The rotating nozzle 3 is installed in the mounting hole 214. The rotating nozzle 3 is fixed by inserting the fitting 215 that is adapted to the rotating nozzle 3 and the mounting hole 214 into the mounting hole 214. The fitting 215 is provided with a second water outlet hole 2151 for the rotating nozzle 3 to spray water and a third water outlet hole 2152 that communicates with the first water outlet.
