Detailed Implementation

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] refer to Figure 1-8 As shown, this utility model discloses an adjustable frequency pulse shower head, including a water outlet body 1, a water inlet body 2, a water distribution plate 3, an adjustment component 4, and an impeller 5; The water outlet body 1 is provided with a first water passage chamber 11, a second water passage chamber 12, and at least two water outlet chambers 13; the first water passage chamber 11 is connected to the water inlet body 2 and is provided with a first water outlet 111 and a second water outlet 112 respectively connected to the second water passage chamber 12; the second water passage chamber 12 is provided with a first water inlet 121 and a second water inlet 122 respectively connected to the first water outlet 111 and the second water outlet 112, and a third water outlet 123 respectively connected to each water outlet chamber 13; each water outlet chamber 13 is provided with a shower spray hole 131; The water distribution plate 3 is set in the first water passage chamber 11 and rotates under the control of the adjustment component 4 to adjust the water passage cross section of the first water outlet 111 and the second water outlet 112. The impeller 5 is located in the second water passage chamber 12 and rotates under the interaction of the water flow entering through the first water inlet 121 and the second water inlet 122 to open and close the third water outlet 123.

[0027] With the above solution, this utility model only requires the user to operate the adjustment component 4 to rotate the water distribution plate 3, thereby adjusting the flow rate from the first water outlet 111 and the second water outlet 112 to the second water distribution plate 12. This also adjusts the flow rate of the first water inlet 121 and the second water inlet 122. As a result, the rotation speed of the impeller 5 is changed under the interaction of the two water flows with different flow rates, which in turn changes the pulse frequency, realizing the pulse frequency adjustment of the shower head to meet the needs of different usage scenarios. Furthermore, by rotating the water distribution plate 3 to adjust the flow rate, stepless adjustment of the pulse frequency can be achieved, which has extremely high flexibility.

[0028] The following are specific embodiments of the present invention.

[0029] The first outlet 111 and the second outlet 112 can be located at the bottom of the first water passage chamber 11 so that the water distribution plate 3 can be more easily opened or covered. The first inlet 121 and the second inlet 122 are located on the side wall of the second water passage chamber 12 so that the water flow entering from the two inlets 122 can directly generate thrust or resistance on the blades of the impeller 5, thereby changing the rotational speed of the impeller 5. At the same time, a first flow channel 14 and a second flow channel 15 are provided between the first water passage chamber 11 and the second water passage chamber 12. The two ends of the first flow channel 14 are respectively connected to the first outlet 111 and the first inlet 121, and the two ends of the second flow channel 15 are respectively connected to the second outlet 112 and the second inlet 122.

[0030] Furthermore, the circumferential surface of the second water passage cavity 12 is provided with a first arc-shaped cavity 16 and a second arc-shaped cavity 17 that are not interconnected. The first arc-shaped cavity 16 and the second arc-shaped cavity 17 surround the second water passage cavity 12, and the first arc-shaped cavity 16 is a superior arc and the second arc-shaped cavity 17 is a inferior arc. The bottom wall of the first arc-shaped cavity 16 is provided with a first water passage hole 161 that communicates with the first flow channel 14, and its side wall is connected to several first water inlets 121. The bottom wall of the second arc-shaped cavity 17 is provided with a second water passage hole 171 that communicates with the second flow channel 15, and its side wall is connected to a second water inlet 122. In this embodiment, the flow rate of the first inlet 121 is mainly used to drive the impeller 5 to rotate, while the flow rate of the second inlet 122 slows down the impeller 5. Therefore, when all the water flows through the first flow channel 14, the impeller 5 rotates at its fastest speed and the pulse frequency of the water splash is also the highest. As the second outlet 112 gradually opens, the speed of the impeller 5 decreases accordingly, and the pulse frequency of the water splash also decreases accordingly.

[0031] The water inlet angle of the second water inlet 122 is set to any angle within the range of conflicting angle (opposite direction) to the same angle (same direction) relative to the first water inlet 121. When it is a conflicting angle, the first flow channel 14 must be kept in a normally open state (the flow rate can be adjusted, but water must be maintained). When it is any angle within the direction of the axis of rotation of the same angle, the first flow channel 14 can be in a closed state. The purpose of this setting is to ensure that the impeller 5 is at least kept rotating in order to achieve pulse water output and to prevent the impeller 5 from stopping and blocking any water outlet chamber 13, causing uneven water output from the shower head.

[0032] The aforementioned water outlet body 1 comprises a split upper plate 1a, a middle plate 1b, and a lower plate 1c, which are stacked sequentially and pre-fixed with screws. Welding is performed at the joints to ensure a tight seal. Thus, the split design of the upper plate 1a, middle plate 1b, and lower plate 1c facilitates the formation of the internal chambers, inlet / outlet, and flow channels of the water outlet body 1. Specifically, the first water passage cavity 11, the second water passage cavity 12, the first arc-shaped cavity 16, and the second arc-shaped cavity 17 are all located on the upper surface of the upper plate 1a to facilitate the assembly of the water distribution plate 3 and the impeller 5. Each water outlet cavity 13 is located between the middle plate 1b and the lower plate 1c, and the first flow channel 14 and the second flow channel 15 are located between the upper plate 1a and the middle plate 1b.

[0033] The first water passage chamber 11 is provided with a water inlet cover 6; the adjustment component 4 includes a rotating shaft 41, a gear 42, a rack 43 and a button 44; the water inlet cover 6 is connected to the water inlet body 1 to realize water inlet of the first water passage chamber 11; the rotating shaft 41 is rotatably connected to the water distribution plate 3 and passes through the water inlet cover 6 in a dynamic seal; the gear 42 is disposed on the surface of the water inlet cover 6 and coaxially connected to the outer end of the rotating shaft 41; the rack 43 is slidably engaged on the surface of the water inlet cover 6 and meshes with the gear 42; the button 44 is drively connected to the rack 43 and pushes the rack 43 to slide under the operation of the user.

[0034] Furthermore, one end of the rack 43 meshes with the gear 42, and the other end is provided with a pressing bevel 431; a pressing strip 45 is connected to the inner end of the button 44; the pressing strip 45 is radially slidably fitted on the surface of the water inlet body 2, and its end is slidably fitted on the pressing bevel 431, so as to convert the pressure on the button 44 into the power of the rack 43. The pressing strip 45 serves to fix the position of the button 44, so that after the shower head housing is assembled, the button 44 will not fall off the shower head handle.

[0035] Meanwhile, the surface of the water inlet cover 6 is fitted with a guide cover 7, which is provided with a guide hole 71; the other end of the rack 43 is provided with a sliding part 432 that slides in the guide hole 71, and the pressing inclined surface 431 is provided at the tail end of the sliding part 432; the water route of the water inlet cover 6 is sealed by the guide cover 7, and a guide groove 61 opposite to the guide hole 71 is provided.

[0036] In addition, a special-shaped sealing ring 46 is provided between the circumference of the aforementioned rotating shaft 41 and the water inlet cover 61 to achieve dynamic sealing; a limiting ring 411 is provided on the circumference of the rotating shaft 41 to abut against the inner wall of the water inlet cover 61, and a spring 47 is provided between the rotating shaft 41 and the water distribution plate 3. The elastic force of the spring 47 can make the water distribution plate 3 press against the bottom wall of the first water passage cavity 11 to improve the sealing effect of the corresponding water outlet.

[0037] The impeller 5 is equipped with a water-shielding baffle 51 for opening and closing the third outlet 123.
