Abstract
Description

[0003] The shower is a shower that is often used in the bathroom. At present, high-end showers on the market usually have multiple water modes, which are roughly divided into two types: one is to divide the multiple water outlets of the shower head into multiple combinations, and one water outlet combination usually corresponds to one water mode, that is, the same water outlet only sprays one water flow, but since different shaped water outlets need to be designed, the processing is not simple, and the switching structure is complex, which makes it unstable when switching water flow, affecting the user's experience; the other is that the shower head has two water modes, and although the same water outlet is used to spray water (that is, the same water outlet sprays two water flows), the water mode is relatively simple, and the simple change of the water flow does not bring good user experience.

[0036] This invention proposes an embodiment of a shower head, which has three water chambers inside, and all three water chambers are connected to the water outlet, so that the shower head has three water outlet modes under the premise of water outlet from the same hole.
[0037] Please see FIG. 1 to FIG. 6 In one embodiment of the present invention, the shower head 10 includes a shower body 100, a water distribution plate 200, a water path switching assembly 300, and a water outlet assembly 400; the shower body 100 is provided with a water inlet channel 110, a first water chamber 120, a second water chamber 130, and a third water chamber 140, wherein the water inlet channel 110 is optionally connected to the first water chamber 120, the second water chamber 130, and the third water chamber 140; the water distribution plate 200 is located between the second water chamber 130 and the third water chamber 140. Between the cavities 140, the water distribution plate 200 is provided with a water passage hole 210; the water path switching component 300 is movably disposed in the first water cavity 120, and the water path switching component 300 can make the first water cavity 120 intermittently connected with the second water cavity 130 and the third water cavity 140 respectively; the water outlet component 400 is disposed on the shower body 100, the water outlet component 400 is connected with the third water cavity 140, and is connected with the second water cavity 130 through the water passage hole 210.
[0038] Specifically, the shower head body 100 has a water inlet end and a water outlet end. The water inlet end is connected to a water inlet pipe, and the water outlet end is used to dispense water for user use. A water inlet channel 110 is provided inside the shower head body 100. This water inlet channel 110 can selectively communicate with the first water chamber 120, the second water chamber 130, and the third water chamber 140, with each water chamber corresponding to a different water outlet mode. The shower head body 100 includes a housing 11 and a panel 12, which together form a mounting cavity for installing other components of the shower head 10. Further, the shower head body 100 also includes a mounting base 900, which, together with the panel 12, forms the first water chamber 120, the second water chamber 130, and the third water chamber 140.
[0039] The water divider plate 200 is disposed between the second water cavity 130 and the third water cavity 140. The water divider plate 200 can be disposed within the mounting base 900 to divide the space enclosed by the mounting base 900 and the panel 12 into the second water cavity 130 and the third water cavity 140. Alternatively, the water divider plate 200 can also be disposed between the mounting base 900 and the panel 12, with the panel 12, water divider plate 200, and mounting base 900 stacked to divide the space enclosed by the mounting base 900 and the panel 12 into the second water cavity 130 and the third water cavity 140. The panel 12, water divider plate 200, and mounting base 900 can be connected by screws, snap-fit, or other connection methods. In this embodiment, the panel 12, water divider plate 200, and mounting base 900 are connected by welding, thus ensuring the airtightness of the connection between the panel 12, water divider plate 200, and mounting base 900 and preventing water leakage.
[0040] The water path switching component 300 is movably disposed in the first water chamber 120. Its main function is to move so that the first water chamber 120 is intermittently connected to the second water chamber 130 and the third water chamber 140, respectively, so that water entering the first water chamber 120 can flow to the second water chamber 130 and the third water chamber 140 respectively. It should be emphasized that, in this embodiment, the water in the first water chamber 120 can only flow to one of the second water chamber 130 or the third water chamber 140 at the same time, and cannot flow to the second water chamber 130 and the third water chamber 140 simultaneously, so as to ensure the water outlet pattern when the water entering the first water chamber 120 flows out through the water outlet component 400. Of course, in other embodiments, the water in the first water chamber 120 can be set to flow into the second water chamber 130 and the third water chamber 140 simultaneously at the same time. To ensure the water outlet mode when the water entering the first water chamber 120 flows out through the water outlet assembly 400, the flow rates of the water flowing into the second water chamber 130 and the third water chamber 140 simultaneously need to be set to different flow rates. Furthermore, to further improve the water outlet effect, the flow rate of the water flowing into the second water chamber 130 and the third water chamber 140 simultaneously can be switched back and forth, instead of always being in a fixed flow rate state. It is only necessary to ensure that the flow rates of the water flowing into the second water chamber 130 and the third water chamber 140 are different within the same time period.
[0041] There are multiple design options for the movement of the water path switching component 300 within the first water cavity 120. Specifically, the water path switching component 300 can move horizontally within the first water cavity 120 to intermittently connect the first water cavity 120 with the second water cavity 130 and the third water cavity 140, respectively; alternatively, the water path switching component 300 can move vertically within the first water cavity 120 to intermittently connect the first water cavity 120 with the second water cavity 130 and the third water cavity 140, respectively; furthermore, the water path switching component 300 can also rotate within the first water cavity 120 to intermittently connect the first water cavity 120 with the second water cavity 130 and the third water cavity 140, respectively. There are many possible movement methods for the water path switching component 300, as long as they achieve the intermittent connection between the first water cavity 120 and the second water cavity 130 and the third water cavity 140, and no specific limitation is imposed.
[0042] The water outlet assembly 400 is disposed on the shower body 100. The water outlet assembly 400 is connected to the third water chamber 140 and to the second water chamber 130 through the water passage hole 210. The water in the shower body 100 will eventually flow out through the water outlet assembly 400.
[0043] The shower head 10 of this application has three water spray modes: a fine spray mode, a shower spray mode, and a dancing spray mode, as detailed below: Please see FIG. 16 and FIG. 17 When the shower head 10 is in the granular water spray mode, the water inlet channel 110 is connected to the third water chamber 140. After the water enters the third water chamber 140, it flows out through the water outlet assembly 400. In this mode, the water spray is in the form of dispersed granules and flows out from the water outlet assembly 400. Please see FIG. 14 and FIG. 15 When the shower head 10 is in the shower spray mode, the water inlet channel 110 is connected to the second water chamber 130. After the water enters the second water chamber 130, it flows directly to the water outlet assembly 400 through the water passage 210 and then flows out through the water outlet assembly 400. In this mode, the water spray flows out from the water outlet assembly 400 in a columnar shape. Please see FIG. 10 to FIG. 13When the shower head 10 is in the water spray mode, the water inlet channel 110 is connected to the first water chamber 120. After the water enters the first water chamber 120, the water flow will intermittently flow to the second water chamber 130 or the third water chamber 140 under the action of the water path switching component 300. The water entering the second water chamber 130 flows directly to the water outlet component 400 through the water passage 210 and then flows out through the water outlet component 400. The water entering the third water chamber 140 flows out through the water outlet component 400. In this mode, water flows alternately from the second water chamber 130 and the third water chamber 140 from the spout assembly 400. Because the water flow direction differs between the second and third water chambers, the water droplets from the second chamber 130 are columnar, while those from the third chamber 140 are diffused granular. Therefore, in the "dancing water" mode, the water droplets are a combination of columnar and diffused granular patterns. These two water droplet effects correspond to the second and third water chambers 130 and 140, respectively, and the two states switch intermittently to achieve the dancing effect. For example, when the shower head 10 is in use and in the "dancing water" mode, starting from second 0, the odd-numbered seconds are all columnar water, and the even-numbered seconds are all diffused granular water, with the two states switching intermittently to achieve the dancing effect.
[0044] It should be emphasized that when the shower head 10 is in any of the three modes of granular water spray mode, shower water spray mode, or dancing water spray mode, since the first water chamber 120, the second water chamber 130, and the third water chamber 140 are connected by gaps or holes, when the water inlet channel 110 connects to any one of the first water chamber 120, the second water chamber 130, or the third water chamber 140, there will also be a small amount of water in the other two water chambers. Since the water in the other two water chambers has no pressure and no water source, it cannot flow. Therefore, it does not affect the overall water output mode of the shower head 10, and this small amount of water can be ignored.
[0045] The shower head 10 of the present invention includes a shower body 100, a water distribution plate 200, a water path switching assembly 300, and a water outlet assembly 400; the shower body 100 is provided with a water inlet channel 110, a first water chamber 120, a second water chamber 130, and a third water chamber 140, wherein the water inlet channel 110 is optionally connected to the first water chamber 120, the second water chamber 130, and the third water chamber 140; the water distribution plate 200 is located between the second water chamber 130 and the third water chamber 140. The water distribution plate 200 is provided with a water passage hole 210; the water path switching component 300 is movably disposed in the first water chamber 120, and the water path switching component 300 allows the first water chamber 120 to be intermittently connected to the second water chamber 130 and the third water chamber 140 respectively; the water outlet component 400 is disposed in the shower head body 100, the water outlet component 400 is connected to the third water chamber 140, and is connected to the second water chamber 130 through the water passage hole 210. The shower head body 100 is provided with three water chambers, and the water inlet channel 110 can be selectively connected to any one of the three water chambers. Each water chamber corresponds to a water outlet mode, and water is discharged from all three water chambers through the water outlet component 400. That is, water is discharged from all three water chambers through the same hole to form different water spray patterns. Accordingly, under the premise of water discharge from the same water outlet hole, the diversity of water discharge of the shower head 10 can be improved.
[0046] Please see FIG. 3 to FIG. 6 In one embodiment, the first water cavity 120 includes a first settling tank 121 and a second settling tank 122 formed at the bottom of the first settling tank 121. The bottom of the second settling tank 122 is provided with a first water outlet 122a and a second water outlet 122b. The first water outlet 122a communicates with the third water cavity 140, and the second water outlet 122b communicates with the second water cavity 130. The water path switching assembly 300 includes an impeller 310 and an internal gear 320. The impeller 310 is connected to the internal gear 320, and the impeller 310 is installed on the third water cavity 140. A settling tank 121 is provided, and the internal gear 320 is installed in the second settling tank 122. The internal gear 320 is provided with an opening 321. The internal gear 320 has a first switching position and a second switching position. The impeller 310 is used to drive the internal gear 320 to switch back and forth between the first switching position and the second switching position. When the internal gear 320 is in the first switching position, the opening 321 is connected to the first water outlet 122a. When the internal gear 320 is in the second switching position, the opening 321 is connected to the second water outlet 122b.
[0047] Specifically, the internal spaces of the first settling tank 121 and the second settling tank 122 form the first water cavity 120. The shapes of the first settling tank 121 and the second settling tank 122 can be rectangular, circular, rhomboid, or other shapes, without specific limitations. In this embodiment, both the first settling tank 121 and the second settling tank 122 are circular, and they can be formed on the mounting base 900. The impeller 310 is connected to the internal gear 320. The rotation of the impeller 310 can drive the internal gear 320 to rotate. The impeller 310 can be snapped into the internal gear 320, fixed with screws, or the impeller 310 and the internal gear 320 can be integrated, or other methods can be used for connection. The connection method between the impeller 310 and the internal gear 320 is not limited, as long as the impeller 310 can drive the internal gear 320 to rotate, so that the internal gear 320 can switch back and forth between the first switching position and the second switching position. The first water inlet 122a communicates with the third water cavity 140, and the second water inlet 122b communicates with the second water cavity 130. The internal gear 320 is installed in the second settling tank 122 and blocks either the first water inlet 122a or the second water inlet 122b. An opening 321 is provided on the internal gear 320, which can communicate with either the first water inlet 122a or the second water inlet 122b, so that the first water cavity 120 communicates with the third water cavity 140 or with the second water cavity 130. When the internal gear 320 is in the first switching position, the opening 321 is connected to the first water inlet 122a. At this time, the water in the first water chamber 120 will flow through the opening 321 and the first water inlet 122a to the third water chamber 140. After entering the third water chamber 140, the water flows out through the water outlet assembly 400. At this time, the water droplets flow out from the water outlet assembly 400 in a dispersed particle shape. When the internal gear 320 is in the second switching position, the opening 321 is connected to the second water inlet 122b. At this time, the water in the first water chamber 120 will flow through the opening 321 and the second water inlet 122b to the second water chamber 130. After entering the second water chamber 130, the water flows directly to the water outlet assembly 400 through the water inlet 210, and then flows out through the water outlet assembly 400. At this time, the water droplets flow out from the water outlet assembly 400 in a columnar shape.
[0048] Furthermore, the water path switching assembly 300 also includes an eccentric shaft 330. The impeller 310 and the internal gear 320 are connected via the eccentric shaft 330. The internal gear 320 can rotate around the eccentric shaft 330 as its rotation center to switch back and forth between the first switching position and the second switching position. Specifically, the impeller 310 and the internal gear 320 are connected via the eccentric shaft 330, and the internal gear 320 can rotate around the eccentric shaft 330 as its rotation center. This water path switching assembly 300 uses rotation to intermittently connect the opening 321 of the internal gear 320 with the first water inlet 122a or the second water inlet 122b.
[0049] Furthermore, the water channel switching component 300 also includes an internal gear ring 340, which is disposed on the wall of the second settling tank 122. The internal gear 320 meshes with the internal gear ring 340 with a small tooth difference. Specifically, the internal gear 320 meshes with the internal gear ring 340 with a small tooth difference, and the number of teeth on the internal gear ring 340 is greater than the number of teeth on the internal gear 320. The internal gear ring 340 can be disposed separately on the wall of the second settling tank 122, or it can be integrally formed with the wall of the second settling tank 122. The internal gear 320 rotates relative to the internal gear ring 340. The rotation center of the internal gear 320 is offset from the center of the circle of the internal gear 320. This arrangement can reduce the rotation of the internal gear 320. The reduction principle can be referred to as the small tooth difference reduction mechanism, which will not be elaborated further.
[0050] The rotation of the internal gear 320 is slowed down primarily because when water enters the first water chamber 120 from the inlet channel 110, the impeller 310 rotates rapidly. If the high-speed impeller 310 drives the internal gear 320 to rotate synchronously, the water spray effect of the shower head 10's "dancing water" mode will be indistinct, resulting in a poor user experience. To avoid this problem, optionally, the rotation of the internal gear 320 is slowed down by reducing the tooth difference and misaligning the rotation center of the internal gear 320 with its own center of rotation, so that the user can clearly see and feel the water spray effect of the "dancing water" mode.
[0051] Please continue reading. FIG. 3 to FIG. 6 Considering that when the internal gear 320 rotates relative to the internal gear ring 340, the internal gear 320 may experience tooth jamming, thus affecting the water output of the shower head chamber, in order to solve this problem, the teeth of the internal gear 320 and the teeth of the internal gear ring 340 can be set in a circular arc shape, so that the internal gear 320 can rotate smoothly relative to the internal gear ring 340, avoiding the problem of tooth jamming.
[0052] Please see FIG. 4 and FIG. 5In one embodiment, the opening 321 extends circumferentially along the internal gear 320, and a reinforcing rib 321a is provided within the opening 321. Specifically, the internal gear 320 is disc-shaped, with teeth arranged around its periphery. The opening 321 is formed on the body of the internal gear 320, extending circumferentially and occupying approximately half the size of the internal gear 320 body. Since the internal gear 320 rotates for extended periods during use, a reinforcing rib 321a is provided within the opening 321 to enhance its structural strength. The reinforcing rib 321a strengthens the structural strength of the opening 321, thereby increasing the overall structural strength of the internal gear 320.
[0053] Please see FIG. 3 to FIG. 6 In one embodiment, a guide ring 350 is provided on the outer periphery of the impeller 310. The guide ring 350 is connected to the bottom of the first settling groove 121, and a guide channel 351 inclined along the circumference of the guide ring 350 is formed on the guide ring 350. Specifically, the impeller 310 is disposed in the first settling groove 121, and the impeller 310 has multiple blades arranged circumferentially. The rotation of the impeller 310 is mainly achieved by the water flow impacting the blades, transferring the kinetic energy of the water flow to the impeller 310, thereby causing the impeller 310 to rotate. To ensure the rotation effect of the impeller 310, a guide ring 350 can be provided on the outer periphery of the impeller 310. A guide groove 121a is formed between the guide ring 350 and the inner wall of the first groove, and the guide groove 121a is arranged in a ring shape. The bottom of the guide channel 121a is provided with a flow inlet 121b. When the water inlet channel 110 is connected to the first water chamber 120, the water in the water inlet channel 110 flows into the guide channel 121a through the flow inlet 121b. Since the guide ring 350 has a guide channel 351 that is inclined along the circumference of the guide ring 350, and the guide channel 351 is at the same height as the blades of the impeller 310 and is directly opposite the blades, the water in the guide channel 121a flows to the impeller 310 through the guide channel 351 and impacts the blades of the impeller 310, causing the impeller 310 to rotate, thereby driving the internal gear 320 to rotate. Inclining the guide channel 351 further enhances the impact effect of the water flow on the blades.
[0054] The number of the flow guiding channels 351 can be one or more. In this embodiment, to ensure the impact effect on the blades of the impeller 310, the number of flow guiding channels 351 is set to multiple, and the multiple flow guiding channels 351 are arranged at intervals along the circumference of the flow guiding ring 350. Preferably, the number of flow guiding channels 351 is set to 3-5.
[0055] Please see FIG. 3 to FIG. 7 ,as well as FIG. 10 to FIG. 17 In one embodiment, the shower head 10 further includes a water distribution component 500, which is disposed in the water inlet channel 110. The water distribution component 500 has a first position, a second position, and a third position, and can switch between the first position, the second position, and the third position. Specifically, the water distribution component 500 can deliver water in the water inlet channel 110 to the first water chamber 120, the second water chamber 130, or the third water chamber 140, respectively. The water distribution component 500 has three positions, each corresponding to one of the three water chambers, and each position is connected to one water chamber.
[0056] Please see FIG. 3 to FIG. 7 In one embodiment, the shower head 10 further includes a third settling groove 600 and a fixed base 700, the fixed base 700 covering the third settling groove 600. The water distribution assembly 500 includes a rotating sleeve 510 and a water distribution plate 520. The rotating sleeve 510 is rotatably disposed on the fixed base 700, and the water distribution plate 520 is disposed on the third settling groove 600. The water distribution plate 520 is connected to the rotating sleeve 510. The rotating sleeve 510 can drive the water distribution plate 520 to switch between the first position, the second position, and the third position by rotating.
[0057] Specifically, the internal space of the third settling tank 600 forms a water distribution cavity. The shape of the third settling tank 600 can be a rectangular settling tank, a circular settling tank, a rhomboid settling tank, or other shapes, without specific limitations. In this embodiment, the third settling tank 600 is a circular settling tank. The third settling tank 600 can be formed on the mounting base 900. The third settling tank 600 has an upward-facing opening. The fixing base 700 covers the third settling tank 600 to close the opening. The water distribution assembly 500 includes a rotating sleeve 510 and a water distribution plate 520. The rotating sleeve 510 is rotatably mounted on the fixing base 700. The rotating sleeve 510 is fixedly connected to the water distribution plate 520. The connection method between the rotating sleeve 510 and the water distribution plate 520 is not limited.
[0058] Please see FIG. 5 to FIG. 7Furthermore, the water distribution plate 520 is provided with a switching port 521, and the bottom of the third settling tank 600 is provided with a first connecting port 610, a second connecting port 620, and a third connecting port 630. The first connecting port 610 communicates with the first water cavity 120, the second connecting port 620 communicates with the second water cavity 130, and the third connecting port 630 communicates with the third water cavity 140. When the water distribution plate 520 is in the first position, the switching port 521 communicates with the first connecting port 610; when the water distribution plate 520 is in the second position, the switching port 521 communicates with the second connecting port 620; and when the water distribution plate 520 is in the third position, the switching port 521 communicates with the third connecting port 630.
[0059] Specifically, the rotating sleeve 510 can rotate to switch the water distribution plate 520 between the first position, the second position, and the third position. The water distribution plate 520 is disc-shaped, and the switching port 521 is opened on the water distribution plate 520. The switching port 521 is a through-hole along the axial direction of the water distribution plate 520. The first connecting port 610, the second connecting port 620, and the third connecting port 630 are formed at the bottom of the third settling tank 600. These ports are spaced apart along the circumferential direction of the bottom of the third settling tank 600. Multiple ports can be provided, with the number of each port equal to the number of the first, second, and third ports. Correspondingly, multiple switching ports 521 are also provided, spaced apart along the circumferential direction of the water distribution plate 520. To avoid the number of first connection ports 610, second connection ports 620, or third connection ports 630 being greater than the number of switching ports 521, which would cause some connection ports to become unusable, the number of switching ports 521 should not be less than the number of first connection ports 610, second connection ports 620, or third connection ports 630.
[0060] Please see FIG. 10 to FIG. 17When the water distribution plate 520 is in the first position, the switching port 521 is connected to the first connecting port 610, and the first connecting port 610 is connected to the first water chamber 120, so that the water inlet channel 110 is connected to the first water chamber 120. At this time, the shower head 10 is in the water spray mode. The water in the water inlet channel 110 will first flow through the drain port 121b to the guide groove 121a. Since the guide ring 350 has a guide channel 351 that is inclined along the circumference of the guide ring 350, the guide channel 351 is at the same height as the blades of the impeller 310, and the guide channel 351 is directly opposite the blades, the water in the guide groove 121a will flow through the guide channel 351 to the impeller 310 and impact the blades of the impeller 310 to make the impeller 310 rotate, thereby driving the internal gear. When the wheel 320 rotates and the internal gear 320 rotates, the opening 321 on the internal gear 320 is intermittently connected to the first water inlet 122a or the second water inlet 122b, so that the water in the first water chamber 120 intermittently flows to the second water chamber 130 or the third water chamber 140. The water entering the second water chamber 130 flows directly to the water outlet assembly 400 through the water inlet 210 and then flows out through the water outlet assembly 400. The water entering the third water chamber 140 flows out through the water outlet assembly 400. In the "Dancing Water Splash" mode, water flows alternately from the second water chamber 130 and the third water chamber 140 through the nozzle assembly 400. Because the water flow directions from the second water chamber 130 and the third water chamber 140 are different, the water spray from the second water chamber 130 is columnar, while the water spray from the third water chamber 140 is diffused granular. Therefore, in the "Dancing Water Splash" mode, the water spray is a combination of columnar and diffused granular spray patterns. The effects of these two spray patterns correspond to the second water chamber 130 and the third water chamber 140, and the two spray states switch intermittently to achieve the dancing effect. For example, when the shower head 10 is used and in "Dancing Water Splash" mode, starting from second 0, the water spray in odd-numbered seconds is columnar, and the water spray in even-numbered seconds is diffused granular, with the two spray states switching intermittently to achieve the dancing effect.
[0061] Please continue reading. FIG. 10 to FIG. 17 When the water distribution plate 520 is in the second position, the second switching port 521 is connected to the second connecting port 620, and the second connecting port 620 is connected to the second water chamber 130, so that the water inlet channel 110 is connected to the second water chamber 130. At this time, the shower head 10 is in the shower spray mode. After the water enters the second water chamber 130, it flows directly to the water outlet assembly 400 through the water passage 210, and then flows out through the water outlet assembly 400. In this mode, the water sprays out in a columnar shape from the water outlet assembly 400.
[0062] Please continue reading. FIG. 10 to FIG. 17When the water distribution plate 520 is in the third position, the third switching port 521 is connected to the third connecting port 630, and the third connecting port 630 is connected to the third water chamber 140, so that the water inlet channel 110 is connected to the third water chamber 140. At this time, the shower head 10 is in the particle water spray mode. After the water enters the third water chamber 140, it flows out through the water outlet assembly 400. In this mode, the water spray is in the form of dispersed particles flowing out from the water outlet assembly 400.
[0063] Please see FIG. 2 , FIG. 10 to FIG. 17 In one embodiment, the water distribution assembly 500 further includes a first sealing gasket 530, which is installed in the third settling tank 600 and located below the water distribution plate 520. Specifically, the shape of the first sealing gasket 530 is adapted to the shapes of the first connecting port 610, the second connecting port 620, and the third connecting port 630. The first sealing gasket 530 is installed between the water distribution plate 520 and the first connecting port 610, the second connecting port 620, or the third connecting port 630, and can play a sealing role to prevent water in the third settling tank 600 from flowing into the first water cavity 120, the second water cavity 130, or the third water cavity 140 through the gap between the water distribution plate 520 and the first connecting port 610, the second connecting port 620, or the third connecting port 630. Further, a second sealing gasket 550 can also be provided on the outer periphery of the water distribution plate 520 to prevent water in the third settling tank 600 from flowing out from the connection between the fixing seat 700 and the third settling tank 600.
[0064] Considering that the first sealing gasket 530 is located below the water distribution plate 520, when the water distribution plate 520 shifts upward, it cannot apply downward pressure to the first sealing gasket 530. Due to the reduced pressure, the first sealing gasket 530 may also move upward under the buoyancy of the water, thus failing to provide a seal. This could allow water in the third settling tank 600 to flow through the gap between the water distribution plate 520 and the first connecting port 610, the second connecting port 620, or the third connecting port 630 into the first water cavity 120, the second water cavity 130, or the third water cavity 140. To avoid this situation, the water distribution assembly 500 further includes an elastic element 540, which is disposed on the rotating sleeve 510 and connected to the water distribution plate 520. The elastic element 540 is a spring, which is installed inside the rotating sleeve 510. One end of the spring is connected to the top wall inside the rotating sleeve 510, and the other end is connected to the water distribution plate 520. The spring can apply a downward elastic force to the water distribution plate 520 so that the water distribution plate 520 can press the first sealing gasket 530.
[0065] Please see FIG. 3 to FIG. 8In one embodiment, the shower head 10 further includes a drive mechanism 800, which is connected to the rotating sleeve 510 and drives the rotating sleeve 510 to rotate, thereby switching the water distribution plate 520 between the first position, the second position, and the third position. Specifically, the drive mechanism 800 is mainly used to drive the rotating sleeve 510 to connect. The type of the drive mechanism 800 is not specifically limited; it may include a worm gear, a worm wheel, and multiple transmission gears 810; or, it may include a sprocket mechanism; or, it may include a linkage mechanism. In this embodiment, the drive mechanism 800 includes a gear 810 and a rack 820. The gear 810 is connected to the rotating sleeve 510, and the rack 820 is movably disposed on the fixed base 700 and meshes with the gear 810. Specifically, the gear 810 is fixedly connected to the rotating sleeve 510, and the rack 820 meshes with the gear 810. When the rack 820 moves, it can drive the gear 810 to rotate. The rotation of the gear 810 will drive the rotating sleeve 510 to rotate, and the rotation of the rotating sleeve 510 will drive the water distribution plate 520 to rotate, thereby allowing the water distribution plate 520 to switch between the first position, the second position, and the third position.
[0066] Please see FIG. 1 , FIG. 2 , FIG. 10 to FIG. 17 Furthermore, the drive mechanism 800 also includes a push rod 830 and a push button 840. The push rod 830 is connected to the rack 820, and the push button 840 is disposed on the push rod 830. The push button 840 protrudes from the outer surface of the housing 11. When the user needs to switch the water output mode of the shower head 10, they only need to push the push button 840 by hand to switch between the three water output modes, which is convenient, quick, and easy for the user to operate.
[0067] Please see FIG. 4 and FIG. 8 In one embodiment, the fixing base 700 is provided with an elastic limiting post 710, and the rack 820 is provided with a first slot 821, a second slot 822, and a third slot 823. When the water distribution plate 520 is in the first position, the elastic limiting post 710 extends into the first slot 821; when the water distribution plate 520 is in the second position, the elastic limiting post 710 extends into the second slot 822; and when the water distribution plate 520 is in the third position, the elastic limiting post 710 extends into the third slot 823.
[0068] Specifically, the fixing seat 700 is provided with a groove, which is located below the rack 820. The elastic limiting post 710 is installed in the groove. The elastic limiting post 710 includes a spring and a limiting head. The spring is disposed in the groove, and the limiting head is connected to the spring. The limiting head abuts against the lower end face of the rack 820. The first slot 821, the second slot 822, and the third slot 823 are formed on the lower end face of the rack 820. Both the limiting head and the rack 820 are made of metal. When the rack 820 moves, the elastic limiting post 710 slides into the first slot 821, the second slot 822, or the third slot 823. Specifically, when the water distribution plate 520 is in the first position, the elastic limiting post 710 extends into the first slot 821; when the water distribution plate 520 is in the second position, the elastic limiting post 710 extends into the second slot 822; and when the water distribution plate 520 is in the third position, the elastic limiting post 710 extends into the third slot 823. When the elastic limiting post 710 extends into the first slot 821, the second slot 822, or the third slot 823, a sound will be emitted when the limiting head and the rack 820 come into contact with the first slot 821, the second slot 822, or the third slot 823, since both the limiting head and the rack 820 are made of metal. The user can hear this sound during use, allowing them to clearly know that the water flow mode of the shower head 10 has been switched to the correct position. Simultaneously, the first slot 821, the second slot 822, and the third slot 823 also limit the displacement of the rack 820, preventing the user from accidentally changing the water flow mode of the shower head 10 due to accidentally touching the push button 840.
[0069] Please see FIG. 10 to FIG. 21 In one embodiment, the water outlet assembly 400 includes a water outlet 410 and a water inlet seat 420, the water outlet 410 and the water inlet seat 420 are connected, the shower body 100 also includes a housing 11 and a panel 12, the housing 11 is connected to the panel 12, the water outlet 410 passes through the panel 12, the top of the water inlet seat 420 communicates with the water passage hole 210, and the side wall of the water inlet seat 420 is provided with a water inlet hole 423.
[0070] Specifically, the housing 11 and the panel 12 enclose a mounting cavity for mounting other components of the shower head 10. A mounting base 900 is installed in the mounting cavity. The mounting base 900 and the panel 12 enclose a first water cavity 120, a second water cavity 130, and a third water cavity 140. The water outlet assembly 400 includes a water outlet 410 and a water inlet seat 420. The water inlet seat 420 is located in the third water cavity 140. The water inlet seat 420 is connected to the water outlet 410, and the water outlet 410 passes through the panel 12. Water from the first water cavity 120, the second water cavity 130, or the third water cavity 140 first flows into the water inlet seat 420 and then flows out through the water outlet 410. The top of the water inlet seat 420 is connected to the water passage hole 210. Water in the second water chamber 130 mainly flows into the water inlet seat 420 from the top through the water passage hole 210, and then flows out through the water outlet 410. To prevent some water in the second water chamber 130 from flowing into the third water chamber 140 from the water passage hole 210, the top of the water inlet seat 420 can be made to abut against the lower surface of the water distribution plate 200 to avoid the above problem. The side wall of the water inlet seat 420 is provided with a water inlet hole 423. Water in the third water chamber 140 mainly flows into the water inlet seat 420 from the side through the water inlet hole 423, and then flows out through the water outlet 410.
[0071] Please see FIG. 23 Furthermore, the water inlet seat 420 includes a body portion 421 and an extension portion 422. The extension portion 422 is connected to the side wall of the body portion 421, and the water inlet hole 423 is formed in the extension portion 422. The body portion 421 has a circular cross-section, and the extension portion 422 consists of two extension segments extending outward from the side wall of the body portion 421, with the water inlet hole 423 formed between the two extension segments. Of course, in other embodiments, the cross-section of the body portion 421 may be square, rhomboid, or other shapes, and there is no specific limitation thereto.
[0072] It should be noted that the inner wall of the main body 421 is tapered from the top of the main body 421 toward the water outlet 410. Specifically, the inner wall of the main body 421 is roughly inverted conical in shape. Water flows vertically from the second water chamber 130 to the water inlet seat 420, and horizontally from the third water chamber 140 to the water inlet seat 420. The water flow directions of the two water chambers are different. When water flows from the second water chamber 130 to the water inlet seat 420, it flows directly to the water outlet 410 or to the inner wall of the main body 421. The water experiences less resistance and flows directly out of the water outlet 410 along the inner wall of the main body 421, resulting in a columnar water droplet. When water flows from the third water chamber 140 to the water inlet seat 420, it flows to the inner wall of the main body 421. The water experiences greater resistance and does not flow directly out of the water outlet 410 along the inner wall of the main body 421. Instead, the water rotates along the inner wall of the main body 421 and is flung out of the water outlet 410, resulting in a dispersed granular water droplet.
[0073] Please see FIG. 19 and FIG. 23 In one embodiment, the water passage hole 210 and the water outlet 410 are coaxially arranged; alternatively, the radius of the body portion 421 is R, and the distance between the axis of the water passage hole 210 and the axis of the water outlet 410 is L, where R ≥ L > 0. Specifically, to ensure that water flows from the second water chamber 130 through the water passage hole 210 to the water inlet seat 420 and exits through the water outlet 410 in a columnar shape, the water passage hole 210 and the water outlet 410 can optionally be coaxially arranged. Considering the stability of the water flow, preferably, the axis of the water passage hole 210 is located within the radius of the body portion 421, that is, the radius of the body portion 421 is R, and the distance between the axis of the water passage hole 210 and the axis of the water outlet 410 is L, where R ≥ L > 0.
[0074] Please see FIG. 23 In another embodiment, the radius of the body 421 is R, the distance between the inlet end of the water inlet 423 and the axis of the outlet 410 is D, and the distance between the axis of the water passage 210 and the axis of the outlet 410 is L, where 0.9D ≥ L > R. Specifically, when the distance L between the axis of the water passage 210 and the axis of the outlet 410 satisfies 0.9D ≥ L > R, the water in the second water chamber 130 will first enter the water inlet 423 through the water passage 210, then flow through the water inlet 423 to the water inlet seat 420 and out of the outlet 410. Compared with the inlet end of the water inlet 423, the water passage 210 is closer to the axis of the outlet 410, and the resistance when the water flows to the inner wall of the water inlet seat 420 is smaller. At this time, the water splash mode is particulate water with a small particle scattering range (see...). FIG. 21When water from the third water chamber 140 flows into the water inlet seat 420 through the water inlet hole 423, the resistance is greater when the water flows towards the inner wall of the water inlet seat 420 because the inlet end of the water inlet hole 423 is far from the axis of the water outlet 410. At this time, the water splash is a particle water with a large particle scattering range (see...). FIG. 20 ).
[0075] Please see FIG. 2 and FIG. 22 In one embodiment, the number of water outlet assemblies 400 is set to multiple, and the multiple water outlet assemblies 400 are disposed on the panel 12. The number of water passage holes 210 is also set to multiple, and the number of water passage holes 210 corresponds to the number of water outlet assemblies 400. Specifically, in order to ensure the water output effect of the shower head 10, the number of water outlet assemblies 400 is set to multiple, and a water passage hole 210 is provided on the water distribution plate 200 corresponding to the position of each water outlet assembly 400, so as to ensure the water output effect of the second water chamber 130.
[0076] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
