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. Utility Model Content

Therefore, one objective of the present invention is to provide a shower head with a simple structure that enables rotating water flow, thereby optimizing the user's showering experience.

[0006] To achieve the above objectives, this utility model proposes a shower head, which includes: Shower head housing, wherein the shower head housing is provided with a first water flow channel; The water outlet body on the shower head and the shower head housing form a hollow mounting cavity; The water distribution mechanism installed in the mounting cavity has a second water flow channel and a water distribution plate. The second water flow channel connects the first water flow channel and the flow channel on the water distribution plate. A sealing assembly installed in the mounting cavity includes a sealing cover that can rotate relative to the water distribution plate. The sealing cover is provided with a rotating nozzle and a shower head through hole. Both the rotating nozzle and the shower head through hole are connected to the water outlet of the cover surface. Rotating the sealing cover can switch the water outlet of the cover surface between rotating water outlet and shower head water outlet. The rotating nozzle includes: The cavity has a tapered top with a first water nozzle and an annular limiting groove at the bottom. The annular limiting groove is coaxially arranged with the first water nozzle. The cavity has a first channel and a second channel at the annular limiting groove. Water flows into the annular limiting groove from the first channel and / or the second channel, forming a rotating water flow. A rotating body is freely movably disposed within the cavity. The rotating body is provided with a second water spray nozzle and a water inlet hole communicating with the second water spray 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 rotate and spray water.

[0007] According to this utility model, an external water source is introduced into a water distribution mechanism through the shower head shell. The water distribution mechanism is rotatably coupled with a sealing component, allowing the rotating nozzle and shower head through-hole on the sealing component to switch between rotating water output and direct water output. This shower head has multiple functions and can switch the water output state according to different usage scenarios.

[0009] Furthermore, the water inlet holes are multiple, and the multiple water inlet holes are disposed at the bottom of the middle large-sized part of the rotating body and are spaced apart around the axis of the rotating body.

[0010] Furthermore, the isolation zone between two adjacent water inlets forms a water-blocking section.

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.

[0017] 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.

[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 1-6 The implementation method of the shower head proposed in the embodiments of this utility model will be described in detail.

[0020] The shower head according to an embodiment of the present utility model includes: Shower head housing 1, the shower head housing 1 is provided with a first water flow channel 11; The water outlet body 2 on the cover forms a hollow installation cavity with the shower head housing 1. The water distribution mechanism 3 is installed in the installation cavity. The water distribution mechanism 3 is provided with a second water flow channel 31 and a water distribution plate 32. The second water flow channel 31 connects the first water flow channel 11 and the flow channel 321 on the water distribution plate 32. The sealing assembly 4 installed in the installation cavity includes a sealing cover 41 that can rotate relative to the water distribution plate 32. The sealing cover 41 is provided with a rotating nozzle and a shower head through hole 42. Both the rotating nozzle and the shower head through hole 42 are connected to the water outlet body 2 on the cover surface. Rotating the sealing cover 41 can switch the water outlet body 2 on the cover surface between rotating water outlet and shower head water outlet. The rotating nozzle 43 includes: The cavity 433 has a conical constriction at the top and a first water spray nozzle 4311. The bottom of the cavity 433 has an annular limiting groove 4321, which is coaxially arranged with the first water spray nozzle 4311. The cavity 433 has a first channel 4322 and a second channel 4323 at the annular limiting groove 4321. Water flows into the annular limiting groove 4321 from the first channel 4322 and / or the second channel 4323, forming a rotating water flow. Rotating body 434 is freely movable inside cavity 433. Rotating body 434 is provided with second water nozzle 43411 and water inlet hole communicating with second water nozzle 43411 and cavity 433. The lower end of rotating body 434 extends into annular limiting groove 4321. The rotating water flow inside the cavity 433 can drive the lower end of the rotating body 434 to revolve within the annular limiting groove 4321, and the second water nozzle 43411 can remain in contact with the first water nozzle 4311 to rotate and spray water.

[0021] In other words, external water enters the second water flow channel 31 of the water distribution mechanism 3 from the first water flow channel 11 of the shower head housing 1. The second water flow channel 31 flows the water into the flow channel 321 on the water distribution plate 32. The sealing cover 41 covers the flow channel 321, and the rotating nozzle 43 or the shower head through hole 42 on the sealing cover 41 is connected to the flow channel 321 by rotation. When the shower head through hole 42 is connected to the flow channel 321, the water outlet 2 on the cover is sprayed out in the state of shower water. When the rotating nozzle 43 is connected to the flow channel 321, the water outlet 2 on the cover is sprayed out in a rotating manner. Specifically, the water in the flow channel 321 is injected into the cavity 433 from the first channel 4322 or / and the second channel 4323 of the rotating nozzle 43. After entering, the water flows along the annular limiting groove 4321. The flow creates a rotating water flow within the cavity 433. This rotating water flow directly acts on the rotating body 434, providing rotational driving force for its rotation. The top of the cavity 433 is conical and narrowed. Under the influence of the water flow within the cavity 433, the rotating body 434 tends to move towards the top of the cavity 433, keeping the second spray nozzle 43411 abutting against the first spray nozzle 4311 at the top of the cavity 433. Simultaneously, the annular limiting groove 4321 limits the lower end of the rotating body 434, confining it within the annular limiting groove 4321 for circling motion. Thus, the water flow within the cavity 433 is ejected through the water inlet 43421 of the rotating body 434 via the second spray nozzle 43411.

[0022] The cavity 433 is provided with a central pillar 4324 protruding from its bottom wall toward the top of the cavity 433. An annular limiting groove 4321 is formed between the outer peripheral wall of the central pillar 4324 and the inner peripheral wall of the cavity 433. The cavity 433 can be formed by connecting the upper shell 431 and the lower shell 432 to facilitate the installation of the rotating body 434. The first water nozzle 4311 is located on the upper shell 431, and the annular limiting groove 4321, the first channel 4322, and the second channel 4323 are located on the lower shell 432. The water inlet 43421 can be located on the side or bottom of the rotating body 434. The diameter of the outer wall of the second water nozzle 43411 can be larger than the diameter of the first water nozzle 4311. The water outlet end of the rotating nozzle 43 can protrude from the cover surface and exit the water body 2. The shower casing 1, the water outlet body 2, the water distribution mechanism 3, and the sealing assembly 4 can adopt existing structures. The water outlet body 2 includes a first water outlet 21, a second water outlet 22, and a decorative cover 23. The first water outlet 21 is fitted onto the sealing cover 41 so that the shower through hole 42 is connected to the shower water column 211 of the first water outlet 21. The second water outlet 22 is fitted onto the first water outlet 21 so that the shower water column 211 protrudes from the second water outlet 22 and the rotating nozzle 43 is embedded in the convex shell 221 of the second water outlet 22. The decorative cover 23 is fitted onto the second water outlet 22 so that the shower water column 211 and the convex shell 221 protrude from the relief hole 231 of the decorative cover 23. The number of rotating nozzles 43 can be three, and they are spaced apart around the axis of the water outlet body 2. Thus, external water is supplied to the water distribution mechanism 3 through the shower head housing 1. The water distribution mechanism 3 rotatably engages with the sealing component 4, allowing the rotating nozzle 43 and the shower head through-hole 42 on the sealing component 4 to switch between rotating water output and shower head output. This shower head is multifunctional and can switch the water output state according to different usage scenarios.

[0023] Optionally, the rotating body 434 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 434 is used to mate with the tapered constriction at the top of the cavity 433, the middle part of the rotating body 434 is used to mate with the inner wall of the middle part of the cavity 433, and the bottom of the rotating body 434 is used to mate with the annular limiting groove 4321. When the rotating body 434 revolves, the top of the rotating body 434, in mate with the tapered constriction, acts as a kind of pivot point, and the middle part of the rotating body 434, in contact with the inner wall of the cavity 433, provides a supporting abutment. This allows the rotating body 434 to rotate simultaneously with its revolution, thus reducing the rotational resistance of the rotating body 434 and improving the smoothness of its rotation. The bottom of the rotating body 434, in mate with the annular limiting groove 4321, restricts the lower end of the rotating body 434 to rotate along a designated path. The cavity 433 and the rotating body 434 are arranged to match the contour formed by their revolution. The bottom of the rotating body 434 is provided with a limiting post 43423, which is coaxially arranged with the second water nozzle 43411.

[0024] Furthermore, there are multiple water inlets 43421, which are located at the bottom of the large central section of the rotating body 434 and spaced apart around the axis of the rotating body 434. Understandably, the large central section of the rotating body 434 provides space for the multiple water inlets 43421. Distributing the multiple water inlets 43421 spaced apart around the axis allows the rotating water flow within the annular limiting groove 4321 to enter each water inlet 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 43421. This reduces jamming caused by uneven force during rotation of the rotating body 434, ensuring stable rotation speed and uniform water flow during showering. Meanwhile, the multi-inlet design of the 43421 water inlet hole can improve water intake efficiency, avoid water spray interruption caused by blockage of a single hole, and ensure the continuity of the shower process.

[0025] Furthermore, the isolation zone between adjacent water inlets 43421 forms a water-blocking section 43422. Understandably, the water-blocking section 43422 serves as the outer wall of the water inlets 43421, and also increases the force exerted by the rotating water flow on the rotating body 434, allowing the rotating water flow to more easily drive the rotating body 434 to rotate. The multiple water-blocking sections 43422 are arranged radially.

[0026] Optionally, the outer peripheral wall of the second water nozzle 43411 is constricted along the water flow direction. Understandably, by constricting the outer peripheral wall of the second water nozzle 43411, the second water nozzle 43411 can fit more closely to the inner wall of the first water nozzle 4311, reducing the obstruction of the second water nozzle 43411 by the first water nozzle 4311, increasing the rotation angle of the second water nozzle 43411, and achieving a larger range of rotational spray. Specifically, the cavity 433 extends downwards from the first water nozzle 4311 with an annular protrusion 4312. The annular protrusion 4312 has a conical constriction, and the top of the conical constriction is provided with the second water nozzle 43411. The rotating body 434 has a groove 43412 for installing a sealing ring. The sealing ring abuts against the lower end face of the annular protrusion 4312 to prevent water from entering through the gap between the conical constriction and the rotating body 432.

[0027] Optionally, both the first channel 4322 and the second channel 4323 are tangentially connected to the annular limiting groove 4321. Understandably, the first channel 4322, with water flowing into it tangentially to the annular limiting groove 4321, minimizes the impact force on the inner and outer walls of the annular limiting groove 4321, allowing water to flow smoothly into the annular limiting groove 4321 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 4322 and the second channel 4323 can be symmetrically distributed with a 180° rotation.

[0028] Furthermore, the rotating body 434 includes a first part 4341 and a second part 4342 connected to the first part 4341. A second water nozzle 43411 is disposed in the first part 4341, and a water inlet 43421 is disposed in the second part 4342. Understandably, by separating the rotating body 434 into two parts, the processing difficulty of the rotating body 434 can be greatly reduced, thereby reducing manufacturing costs. Water flows into the first part 4341 through multiple water inlets 43421, then is collected by the second part 4342 and ejected from the second water nozzle 43411. The first part 4341 and the second part 4342 can be connected by a sleeve or by ultrasonic welding.

[0029] Optionally, the water distribution mechanism 3 is equipped with a third water flow channel 33 and a switching switch 34. The shower head housing 1 has a spray gun outlet 12 on the top of its outer peripheral wall. The switching switch 34 can connect the first water flow channel 11 to the third water flow channel 33 or the second water flow channel 31. Understandably, the third water flow channel 33 connects to the spray gun outlet 12, and the switching switch 34 can be operated by rotation or pressing. When the switching switch 34 connects the first water flow channel 11 to the third water flow channel 33, water flows through the third water flow channel 33 and sprays out from the spray gun outlet 12, forming a concentrated and powerful spray gun flow, suitable for cleaning hard-to-reach corners in the bathroom and rinsing hair. When switched to connect to the second water flow channel 31, the rotating or shower head water flow mode is restored. This design further enriches the shower head's functions, allowing for simple switching to meet diverse needs such as daily showering and precise cleaning, improving the product's practicality and user experience.
