CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority benefit of China application serial no. 202011196033.X, filed on Oct. 30, 2020. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
BACKGROUND
Technical Field
The disclosure relates to a field of sanitary products, and in particular, relates to a shower head.
Description of Related Art
Regarding the shower heads provided by the prior art, the flow adjusting devices are usually arranged in the water inlet channels of the shower heads, and the adjusting devices are completely soaked in water. In the case that the amount of flowing is adjusted by driving an adjusting device, with presence of the water pressure, the switching pressure may be relatively large and such switching is thus laborious. Poor user experience is inevitably provided. Generally, when a shower head is required to be turned off, the shower head is turned off through the water outflow switch away from the shower head. When holding a shower head in one hand, if a user wants to turn off the shower head temporarily, the user has to go near the water outflow switch to turn off the shower head, and the user thus experiences an inconvenient user experience.
SUMMARY
The following is a brief description of the subject to be explained in detail in the specification, and the brief description is not intended to limit the protection scope of the claims.
To accomplish the foregoing purpose, the following technical solutions are adopted.
The embodiments of the disclosure provide a shower head including a shower head body, a first leather cup, a surface cover assembly, a water dispensing plate, and an adjusting device. The shower head body is provided with a water inlet channel. The first leather cup is installed in the water inlet channel and is provided with a first water outlet communicating with the water inlet channel. The water dispensing plate is located between the shower head body and the surface cover assembly, hermetically encloses an installation cavity and a water outflow cavity respectively together with the shower head body and the surface cover assembly, and is provided with a first water passage hole communicating with the water outflow cavity. The adjusting device includes a driving mechanism and a rotating mechanism. The driving mechanism is rotatably connected to the shower head body and includes an operating portion at least partially exposed outside the shower head body. The rotating mechanism is located inside the installation cavity and hermetically abuts against the first leather cup and the water dispensing plate. The rotating mechanism is provided with a second water passage hole. The driving mechanism drives the rotating mechanism to rotate, so as to adjust a water outflow area which is formed by the overlapped area of the first water outlet and the second water passage hole. A flowing amount of the shower head may be adjusted and water outflowing may be paused. Further, water may only flow out from the first water passage hole after flowing from the first water outlet to the second water passage hole, and in this way, the adjusting device may not be soaked in water.
To make the aforementioned more comprehensible, several embodiments accompanied with drawings are described in detail as follows.

During implementation, in this embodiment, as shown in FIG. 15 and FIG. 17 to FIG. 19, the handle portion 12 is configured to communicate with the external water outlet, and water flows into the head portion 11 through the water inlet channel. When flowing inside the head portion 11, water first flows out of the water inlet channel from the first water outlet 21 of the first leather cup 2, flows towards the second leather cup 53 through the second water passage hole 51111 on the rotation plate 51, and flows out through the third water passage hole 531. The water then enters the water outflow cavity after passing through the first water passage hole 712 and the fourth water passage hole 7151 of the water dispensing plate 7 and is sprayed from the water outflow columns 812 of the water outflow plate 8. In an initial state, the positioning bead 312 of the elastic spring plunger 3 is located in the positioning groove 5112 located in the middle part. Herein, a water outflow area which is an overlapped area of the first water outlet 21 on the first leather cup 2 and the second water passage hole 51111 on the rotation plate 51 is only half of the first water outlet 21, which is a low water outflow mode. In the initial state, one end of the rocker button 41 close to the handle portion 12 is pressed, and the rocker button 41 drives the driving plate 42 to rotate counterclockwise. The driving rack 421 drives the transmission rack 52, so that the rotation plate 51, after rotating counterclockwise, is meshed with the transmission rack 52 through the driving rack 421 for positioning. During this process, the positioning bead 312 of the elastic spring plunger 3 moves in a clockwise direction relative to the rotation plate 51 into the adjacent positioning groove 5112 to perform positioning at the same time. Herein, the first water outlet 21 on the first leather cup 2 completely overlaps the second water passage hole 51111 on the rotation plate 51, which is a high water outflow mode. In the initial state, one end of the rocker button 41 away from the handle portion 12 is pressed, and the rocker button 41 drives the driving plate 42 to rotate clockwise. The driving rack 421 drives the transmission rack 52, so that the rotation plate 51, after rotating clockwise, is meshed with the transmission rack 52 through the driving rack 421 for positioning. During this process, the positioning bead 312 of the elastic spring plunger 3 moves in a counterclockwise direction relative to the rotation plate 51 into the adjacent positioning groove 5112 to perform positioning at the same time. Herein, the first water outlet 21 on the first leather cup 2 is blocked by the first sector plate 511 next to the second water passage hole 51111, and a minimum overlapped area is provided, which is a water outflow pause mode. By pressing the rocker button 41, the shower head may be adjusted to be switched between the three modes of the low water outflow mode, the high water outflow mode, and the water outflow pause mode. It should be understood that, in this embodiment, the driving rack 421 and the transmission rack 52 rotate at the same angle and may also rotate at multiple angles by setting the two racks to be provided with different diameters. The elastic spring plunger 3 is provided for enhancing the stability of positioning and a sense of gear shifting, and if the elastic spring plunger 3 is removed, instead of switching between the three modes of the low water outflow mode, the high water outflow mode and the water outflow pause mode, the shower head may be adjusted within a broader range to acquire more different flowing amount. In the case that the elastic spring plunger 3 is removed or another positioning groove 5112 is added, by changing the numbers or sizes of the first water outlet 21 and water passage holes and adding corresponding waterways in the water outflow cavity, water outflowing may be switched and the flowing amount may be adjusted at the same time.

The rotating mechanism 5 is driven by the driving mechanism 4 to rotate to adjust the water outflow area which is formed by the overlapped area of the first water outlet 21 and the second water passage hole 811. In this way, water may flow into the water outflow cavity only after flowing towards the first water passage hole 712 of the water dispensing plate 7 through the first water outlet 21 and the second water passage hole 811. The water may not flow into other positions of the installation cavity, and the adjusting device may not be soaked in the water. The rotating mechanism 5 is driven to rotate through the driving mechanism 4, such that the size of the overlapped area of the first water outlet 21 and the second water passage hole 811 may be adjusted, and the flowing amount may be adjusted or water outflowing may be paused. In this embodiment, the water inlet channel of the shower head body 1 is hermetically provided with the first leather cup 2. The first leather cup 2 is provided with the first water outlet 21, such that water in the water inlet channel may flow into the shower head body 1 only through the first water outlet 21 on the first leather cup 2, water leakage is thereby prevented from occurring, and the adjusting device is prevented from being soaked in the water. In this embodiment, the driving mechanism 4 includes the rocker button 41 and a driving plate 42. The rocker button 41 is rotatably connected to the shower head body 1 to form the operating portion.

The rotating mechanism includes the transmission rack 52 that is rotatably meshed with the driving rack 421. The rocker button 41 may be pressed to drive the driving rack 421 to swing, the transmission rack 52 of the rotating mechanism 5 may be driven to rotate through the driving rack 421, and in this way, the flowing amount may be adjusted or water outflowing may be paused. Further, the driving rack 421 may be matched with the transmission rack 52 to position the rotating mechanism 5. In this embodiment, the rotating mechanism 5 further includes the rotation plate 51 and the second leather cup 53. A surface of the rotation plate 51 facing away from the water dispensing plate 7 abuts against the first leather cup 2. The rotation plate 51 is rotatably connected to the shower head body 1 and is located in the installation cavity, and a surface thereof facing the water dispensing plate 7 is provided with the first installation groove 5111 with an opening facing the water dispensing plate 7. The second water passage hole 51111 is located at the bottom portion of the first installation groove 5111. The transmission rack 52 has an arc shape, is coaxial with the rotation plate 51, is fixed onto the rotation plate 51, and is meshed with the driving rack 421. The second leather cup 53 is hermetically fixed in the first installation groove 5111 and abuts against the water dispensing plate 7, and the third water passage hole 531 communicating with the first water passage hole 712 and the second water passage hole 51111 penetrates the second leather cup 53. In this way, water flowing out of the first water outlet 21 may flow towards the first water passage hole 712 of the water dispensing plate 7 only through the second water passage hole 51111 of the rotation plate 51 and the third water passage hole 531 of the second leather cup 53. The rotating mechanism 5 sandwiched between and hermetically abuts the first leather cup 2 and the water dispensing plate 7. Further, the second leather cup 53 is hermetically installed on the rotation plate 51 through the first installation groove 5111, and in this way, sealing performance is enhanced, water leakage is prevented from occurring, and the adjusting device is prevented from being soaked in water. In this embodiment, the installation cavity of the shower head body 1 is provided with the first rotating shaft 113 extending towards the water dispensing plate 7, and the outer wall of the first rotating shaft 113 is provided with the limiting surface extending outwardly in a radial direction. The rotation plate 51 is sleeved on the first rotating shaft 113 and is sandwiched between the limiting surface and the water dispensing plate 7. The limiting surface and the water dispensing plate 7 limit the position of the rotation plate 51, and the limiting surface allows a space to be kept between the rotation plate 51 and the cavity wall, opposite to the water dispensing plate 7, of the installation cavity of the shower head body 1 and thus facilitates rotation of the rotation plate 51. In this embodiment, the central position of the first rotating shaft is provided with the threaded hole penetrating the first rotating shaft. The water dispensing plate is sleeved on the first rotating shaft and is fixed onto the threaded hole of the first rotating shaft by a screw, and the water dispensing plate is fixed to the shower head body in this way. In this embodiment, a surface of the first leather cup 2 facing the water inlet channel and a surface of the second leather cup 53 facing the rotation plate 51 are both provided with the protruding blocks. The inner cavity wall of the water inlet channel and the bottom portion of the first installation groove 5111 are both provided with the protruding ribs opposite to the protruding blocks. The elastic members are disposed between the protruding blocks and the protruding ribs opposite to each other, such that the first leather cup 2 may always abut against the rotation plate 51, and the second leather cup 53 may always abut against the water dispensing plate 7, sealing performance is thus enhanced, water leakage is effectively prevented from occurring, and the adjusting device is prevented from being soaked in water. In this embodiment, a surface of the rotation plate 51 facing away from the water dispensing plate 7 is circumferentially provided with the three identical positioning grooves 5112. One side, facing away from the positioning groove 5112 in the middle part, of each of the two positioning grooves 5112 located in the upper part and the lower part respectively is provided with the arc-shaped blocking wall 5113. The inner wall of the shower head body 1 opposite to the positioning grooves 5112 is provided with the elastic spring plunger 3, and the elastic spring plunger 3 is configured to be positioned through abutting against the positioning grooves 5112 when the rotation plate 51 rotates. Arrangement of the elastic spring plunger 3 and the positioning grooves 5112 may enhance the sense of gear shifting and at the same time strengthen the stability of the positioning of the rotation plate 51. In this embodiment, the water outflow plate 8 is elastic. A surface of the water dispensing plate 7 opposite to the water outflow plate 8 is provided with the third protruding columns extending in a direction of the water outflow plate 8. The third protruding columns and the water outflow columns 812 are arranged in an alternating manner, and the third protruding columns are configured to press against the water outflow plate 8, such that the water outflow plate 8 is closely attached to the water outflow surface cover 9. In this way, the water outflow columns 812 may extend out of the water outflow surface cover 9 for water outflowing.
