DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference as follows Figures 1-10 The utility model is described as follows:

[0039] Example 1: A water channel switching structure for a shower head includes a shower tray, comprising a front tray 1 and a rear tray 2. The shower tray is provided with three independent water inlet channels, each connected to three water inlets 4. Each water inlet channel is independently responsible for introducing different water flows into the shower tray. Each water inlet channel is connected to a specific water source or water supply system to ensure a stable water supply.

[0040] The front side of the front disc 1 is equipped with several water outlets, carefully positioned for optimal water distribution. Each outlet connects to one of the three water inlet channels, enabling three different water distribution methods. For example, one inlet channel might connect to an outlet that produces a gentle spray, ideal for gently cleansing the skin; another might connect to an outlet that produces a powerful rain shower, quickly washing away dirt; and yet another might connect to an outlet that produces a pulsating massage effect, providing a relaxing experience for the user.

[0041] The rear wall of the rear showerhead 2 is equipped with a circular water inlet trough 3, which acts as a water transfer station and plays a crucial role. At the bottom of the trough 3 is a water inlet port 4, which connects to the interior of the showerhead. Three water inlets 4 are spaced circumferentially around the trough and connect to three separate water inlet channels, enabling independent water supply to each channel. As water flows from the trough 3 into the water inlet port 4, it is distributed to the corresponding water inlet channel according to different needs. This design ensures a stable water flow to each channel, ensuring the proper functioning of the three different water outlet modes.

[0042] A sealing plate 6 is installed within the water inlet trough 3. This sealing plate 6 has a notched groove 62, which blocks the water inlet 4. The water inlet 4 exposed at the notched groove 62 is accessible to water. The sealing plate 6 is rotatable, switching between different water inlets 4. This sealing plate 6 plays a key role in controlling water flow. The notched groove 62 on the sealing plate 6, when in a specific position, blocks the water inlet 4. In other words, under normal conditions, the sealing plate 6 seals the water inlet 4, preventing water from entering.

[0043] And only when the water inlet 4 is exposed at the notch groove 62, can this water inlet 4 be able to let water in. This design ensures the precise control of water flow, and only when necessary will a specific water inlet 4 be opened, thereby realizing the switching of different water outlet modes.

[0044] The rotatable sealing plate 6 is a key design feature of the entire waterway switching structure. By rotating the sealing plate 6, the opening of different water inlets 4 can be precisely switched. For example, to switch from one water outlet mode to another, simply rotate the sealing plate 6 so that the notched groove 62 aligns with the different water inlets 4. This rotation can be achieved manually or through other mechanical means, making it very convenient and quick.

[0045] The sealing plate 6 and the notch groove 62 thereon, as well as the rotatable design of the sealing plate 6, provide a precise and reliable water flow control method for the water path switching structure of the shower head, allowing users to easily switch between different water outlet modes and enjoy a more comfortable shower experience.

[0046] A connecting portion 5 extends forward from the center of the bottom wall of the water inlet trough 3. This connecting portion 5 acts like a pivot, connecting and controlling the various components. A through hole 51 runs through the center of the connecting portion 5, providing space for the installation and movement of other components. An annular limiting ring 52 is installed on the inner wall of through hole 51 to limit the movement of other components.

[0047] The front side of the restriction ring 52 is provided with three forward-extending restriction bars 53. These three restriction bars 53 are spaced evenly around the circumference of the connecting portion 5. The front side of the restriction bars 53 is inclined, and this inclined surface design has a specific function.

[0048] The sealing plate 6 is provided with a connecting strip 61 extending into the through hole 51. The end of the connecting strip 61 is tapered. Similarly, there are three connecting strips 61, and the three connecting strips 61 correspond to the three limiting strips 53. This correspondence ensures that during the movement of the sealing plate 6, the connecting strips 61 can cooperate with the limiting strips 53 to achieve precise control.

[0049] A circular drive portion 7 is also disposed within the through-hole 51. This drive portion 7 is located in front of the restriction ring 52 and inside the three restriction bars 53. Three drive bars 71 are disposed on the outer wall of the drive portion 7, each located between two adjacent restriction bars 53. This arrangement enables the drive portion 7 and drive bars 71 to move within a specific range, thereby controlling the movement of the sealing plate 6. The rear end of the drive bar 71 is tapered, matching the tapered end of the connecting bar 61.

[0050] A pressing rod 72 extends rearward from the driving portion 7 , and the pressing rod 72 passes through the limiting ring 52 and extends to the outside of the through hole 51 .

[0051] In the above technical solution, when the pressing lever 72 is pressed, the driving portion 7 and the driving bar 71 can move forward and backward. As the driving bar 71 moves forward, its rear end contacts the front end of the connecting bar 61. Because the rear end of the driving bar 71 and the front end of the connecting bar 61 are both tapered, this contact between the tapered surfaces causes the sealing plate 6 to move backward and simultaneously rotate. This design allows the movement of the sealing plate 6 to be controlled by operating the pressing lever 72, thereby switching between opening different water inlets 4.

[0052] When the pressing force disappears, the sealing plate 6 returns to its original position under the action of spring 8. Spring 8, located on the rear side of the sealing plate 6, applies a forward force to the sealing plate 6. At this point, the front end of the connecting bar 61 contacts the rear end of the limiting bar 53. Because the rear side of the limiting bar 53 is inclined, contact with the tapered front end of the connecting bar 61 guides the connecting bar 61 forward while continuing to rotate until it enters the position between the two limiting bars 53, facing the driving bar 71, ready for the next pressing action.

[0053] A spring 8 is provided on the rear side of the sealing plate 6 to apply a forward elastic force thereto.

[0054] The rotation of the sealing plate 6 is achieved in the following manner:

[0055] When the pressing rod 72 is pressed, the driving portion 7 and the driving bar 71 move forward. Because the rear end of the driving bar 71 and the front end of the connecting bar 61 are both tapered, when the driving bar 71 moves forward and contacts the connecting bar 61, an oblique thrust is generated. This thrust causes the sealing plate 6 to move backward while the sealing plate 6 is forced to rotate due to the interaction between the tapered surfaces of the connecting bar 61 and the driving bar 71.

[0056] When the pressing force disappears, the spring 8 on the rear side of the sealing plate 6 applies a forward force to reset it. At this point, the front end of the connecting bar 61 contacts the rear end of the limiting bar 53, whose rear side is an inclined surface. Guided by the inclined surface, the connecting bar 61 continues to rotate as it moves forward to return to its original position, until it enters the position between the two limiting bars 53 and faces the driving bar 71, completing one rotation and preparing for the next pressing action to switch the water inlet.

[0057] This rotation method utilizes the tapered surface contact and inclined surface guidance between the components to achieve precise rotation of the sealing plate 6, thereby effectively controlling the opening and closing of the water inlet and achieving the purpose of switching the water discharge mode of the shower head.

[0058] The front side wall of the front showerhead 1 is provided with an opening 11 corresponding to the connection portion 5. This opening 11 provides a passage for the installation and operation of subsequent components. A button 12 is connected to the opening 11. One end of the button 12 is hinged to the showerhead body. This hinged connection allows the button 12 to rotate flexibly within a certain range. The other end of the button 12 abuts against the front end of the push rod 72. When the user presses the button 12, the button 12 transmits pressure to the push rod 72. Due to the hinged connection between the button 12 and the showerhead body, the user can feel a certain amount of feedback during operation, improving the comfort and accuracy of operation.

[0059] With this design, the user can easily control the movement of the push rod 72 by pressing the button 12 on the front panel 1. This movement of the push rod 72 then drives the drive unit 7 and the drive bar 71, ultimately rotating the sealing plate 6 and switching the water inlet 4. This simple and intuitive operation allows users to easily switch the water outlet mode according to their needs during showering.

[0060] The water inlet 4 is located outside the through-hole 51 and is elongated. This placement of the water inlet 4 outside the through-hole 51 is a unique design consideration. This location better aligns with the overall waterway layout, facilitating the receipt of water from the water inlet trough 3 and its orderly channeling into the corresponding water inlet channel.

[0061] The water inlet 4 is designed as an elongated strip, a characteristic that offers numerous advantages. Compared to traditional circular or other shaped water inlets, the elongated water inlet 4, with the same cross-sectional area, has a larger contact area with the water flow, allowing for a more even and smooth flow from the water inlet trough 3. This avoids the problems of turbulent water flow and uneven local pressure that can arise from an improperly shaped water inlet, allowing the water to flow stably into the corresponding water inlet channel. This ensures the stability and consistency of the water flow in various subsequent water outlet modes, contributing to a smoother and more comfortable water flow from the shower head.

[0062] The rear side of the water inlet trough 3 is connected to a water inlet guide 9, and the water inlet trough 3 is connected to the inner cavity of the water inlet guide 9. A positioning column 81 is provided on the inner wall of the water inlet guide 9, and a positioning hole 82 is provided in the center of the sealing plate 6. The spring 8 is connected to the positioning column 81 and the positioning hole 82.

[0063] The existence of the water inlet guide 9 is of great significance. It can guide the water flow into the water inlet trough 3, ensure that the water flow can smoothly reach the water inlet trough 3 according to the established path, and provide a stable water source guarantee for subsequent water distribution and switching operations.

[0064] The inner wall of the water inlet guide 9 is provided with a positioning post 81, corresponding to a positioning hole 82 in the center of the sealing plate 6. The spring 8 is cleverly connected between the positioning post 81 and the positioning hole 82, enabling the spring 8 to precisely perform its function. The combination of the positioning post 81 and the positioning hole 82 provides a secure mounting position for the spring 8, preventing it from shifting or deflecting during operation and ensuring it remains in proper working order.

[0065] On the other hand, when the pressing lever 72 is pressed, the sealing plate 6 moves backward and rotates, and the spring 8 is compressed and stored. Once the pressing force disappears, the spring 8, relying on its own elastic recovery force, can accurately push the sealing plate 6 forward through the connection structure of the positioning column 81 and the positioning hole 82, so that the entire water channel switching structure can be quickly and accurately restored to its initial state or prepared for the next water inlet 4 switching, ensuring the cyclic continuity of the entire water channel switching action and the reliability of the water outlet mode switching.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
