Description

Technical Field

[0001] This invention relates to the field of bathroom technology, and in particular to a shower head. Background Technology

[0002] Showerheads are frequently used in bathrooms. Currently, high-end showerheads on the market typically offer multiple water flow modes, generally falling into two categories: one type divides the showerhead's multiple nozzles into various combinations, with each combination usually corresponding to one water flow mode—meaning only one type of water spray from the same nozzle. However, designing different nozzle shapes is not only inconvenient in manufacturing but also involves complex switching mechanisms, leading to instability when switching water spray patterns and affecting the user experience. The other type features two water flow modes. While these modes use the same nozzle (i.e., two different water spray patterns from the same nozzle), the water flow pattern is relatively limited, and the simple change in water spray pattern fails to provide a good user experience.

[0064] The present application provides an embodiment of a shower head, three water cavities are arranged in the shower head, and the three water cavities are all communicated with a water outlet nozzle, so that the shower head has three water outlet modes under the premise of the same hole water outlet.

[0065] Please refer to Figures 1 to 6 In an embodiment of the present application, the shower head 10 comprises a shower body 100, a water distribution plate 200, a water path switching assembly 300 and a water outlet nozzle assembly 400; the shower body 100 is provided with a water inlet channel 110, a first water cavity 120, a second water cavity 130 and a third water cavity 140, the water inlet channel 110 can selectively communicate with the first water cavity 120, the second water cavity 130 and the third water cavity 140; the water distribution plate 200 is located between the second water cavity 130 and the third water cavity 140, and the water distribution plate 200 is provided with a water passing hole 210; the water path switching assembly 300 is movably arranged in the first water cavity 120, and the water path switching assembly 300 can make the first water cavity 120 intermittently communicate with the second water cavity 130 and the third water cavity 140 respectively; the water outlet nozzle assembly 400 is arranged on the shower body 100, and the water outlet nozzle assembly 400 communicates with the third water cavity 140 and communicates with the second water cavity 130 through the water passing hole 210.

[0066] Specifically, the shower body 100 has a water inlet end and a water outlet end, the water inlet end is connected with the water inlet pipe, and the water outlet end is used to outlet water for user. An inlet water channel 110 is arranged in the shower body 100, the inlet water channel 110 is selectively communicated with the first water cavity 120, the second water cavity 130 and the third water cavity 140, and each water cavity corresponds to one water outlet mode. The shower body 100 comprises a shell 11 and a panel 12, and the shell 11 and the panel 12 enclose an installation cavity for mounting other components of the shower head 10. Further, the shower body 100 further comprises a mounting seat 900, and the mounting seat 900 is enclosed with the panel 12 to form the first water cavity 120, the second water cavity 130 and the third water cavity 140.

[0067] The water distribution plate 200 is arranged between the second water cavity 130 and the third water cavity 140, and the water distribution plate 200 can be arranged in the mounting seat 900 to divide the space enclosed by the mounting seat 900 and the panel 12 into the second water cavity 130 and the third water cavity 140, or the water distribution plate 200 can also be arranged between the mounting seat 900 and the panel 12, and the panel 12, the water distribution plate 200 and the mounting seat 900 are arranged in layers to divide the space enclosed by the mounting seat 900 and the panel 12 into the second water cavity 130 and the third water cavity 140. The panel 12, the water distribution plate 200 and the mounting seat 900 can be connected by screws, can be connected by clamping, or can be connected by other connection modes. In this embodiment, the panel 12, the water distribution plate 200 and the mounting seat 900 are connected by welding, so that the sealing property of the connection between the panel 12, the water distribution plate 200 and the mounting seat 900 can be ensured, and water leakage can be prevented.

[0068] The waterway switching assembly 300 is movably arranged in the first water cavity 120, and its main function is to intermittently communicate the first water cavity 120 with the second water cavity 130 and the third water cavity 140 respectively by moving, so that the water entering the first water cavity 120 can flow into the second water cavity 130 and the third water cavity 140 respectively. It is emphasized here that in the present embodiment, the water in the first water cavity 120 can only flow into one of the second water cavity 130 or the third water cavity 140 at the same time, and cannot flow into the second water cavity 130 and the third water cavity 140 at the same time, so as to ensure the water mode when the water entering the first water cavity 120 flows out through the water outlet nozzle assembly 400. Of course, in other embodiments, the water in the first water cavity 120 can be arranged to flow into the second water cavity 130 and the third water cavity 140 at the same time, in order to ensure the water mode when the water entering the first water cavity 120 flows out through the water outlet nozzle assembly 400, the flow of the water flowing into the second water cavity 130 and the third water cavity 140 at the same time needs to be set to different flow rates, and in order to further improve the water effect, the flow of the water flowing into the second water cavity 130 and the third water cavity 140 at the same time can be switched back and forth, without being always in a fixed flow state, as long as the flow of the water flowing into the second water cavity 130 and the third water cavity 140 at the same time is different in the same time period.

[0069] For the moving mode of the waterway switching assembly 300 in the first water cavity 120, there can be many design ways. Specifically, the waterway switching assembly 300 can move in the first water cavity 120 in the horizontal direction to achieve the function of intermittently communicating the first water cavity 120 with the second water cavity 130 and the third water cavity 140 respectively; or the waterway switching assembly 300 can move in the first water cavity 120 in the vertical direction to achieve the function of intermittently communicating the first water cavity 120 with the second water cavity 130 and the third water cavity 140 respectively; or the waterway switching assembly 300 can also rotate in the first water cavity 120 to achieve the function of intermittently communicating the first water cavity 120 with the second water cavity 130 and the third water cavity 140 respectively. The moving mode of the waterway switching assembly 300 can be various, as long as it can achieve the function of intermittently communicating the first water cavity 120 with the second water cavity 130 and the third water cavity 140 respectively, which is not specifically limited.

[0070] The water outlet nozzle assembly 400 is arranged on the shower body 100, and the water outlet nozzle assembly 400 communicates with the third water cavity 140 and communicates with the second water cavity 130 through the water passing hole 210, and the water in the shower body 100 will eventually flow out through the water outlet nozzle assembly 400.

[0071] The shower head 10 of the present application has three water outlet modes, which are granular water mode, shower water mode and dancing water mode, as follows:

[0072] Please refer to Figure 16 and Figure 17 When the shower head 10 is in the granular water mode, the water inlet channel 110 is in communication with the third water cavity 140, and the water entering the third water cavity 140 flows out through the water outlet nozzle assembly 400. In this mode, the water flow is granular and divergent from the water outlet nozzle assembly 400.

[0073] Please refer to Figure 14 and Figure 15 When the shower head 10 is in the shower water mode, the water inlet channel 110 is in communication with the second water cavity 130, and the water entering the second water cavity 130 flows directly to the water outlet nozzle assembly 400 through the water passing hole 210, and then flows out through the water outlet nozzle assembly 400. In this mode, the water flow is columnar from the water outlet nozzle assembly 400.

[0074] Please refer to Figures 10 to 13 When the shower head 10 is in the dancing water mode, the water inlet channel 110 is in communication with the first water cavity 120, and the water entering the first water cavity 120 flows intermittently to the second water cavity 130 or the third water cavity 140 under the action of the water path switching assembly 300. The water entering the second water cavity 130 flows directly to the water outlet nozzle assembly 400 through the water passing hole 210, and then flows out through the water outlet nozzle assembly 400. The water entering the third water cavity 140 flows out through the water outlet nozzle assembly 400. In this mode, the water flow alternately flows out from the water outlet nozzle assembly 400 from the second water cavity 130 and the third water cavity 140. Since the water flow directions from the second water cavity 130 and the third water cavity 140 are different, the water flow from the second water cavity 130 is columnar, and the water flow from the third water cavity 140 is granular and divergent. Therefore, in the dancing water mode, the water flow is a combination of columnar and granular and divergent water forms. The water outlet effects of the two water flows correspond to the second water cavity 130 and the third water cavity 140, and the two water outlet states are intermittently switched to achieve the dancing effect. For example, when the shower head 10 is started and in the dancing water mode, the water outlet is columnar in odd seconds and granular and divergent in even seconds, and the two water outlet states are intermittently switched to achieve the dancing effect.

[0075] It is emphasized here that when the shower head 10 is in any one of the three modes of particle water mode, shower water mode or dancing water mode, since the first water cavity 120, the second water cavity 130 and the third water cavity 140 are communicated through the gap or the hole, when the water inlet channel 110 communicates any one of the first water cavity 120, the second water cavity 130 or the third water cavity 140, a small amount of water will also exist in the other two water cavities, since the water in the other two water cavities has no pressure and the water has no water source, it cannot flow, thus the water mode of the whole shower head 10 is not affected, and the small amount of water can be ignored.

[0076] The shower head 10 of the present application comprises a shower body 100, a water distribution plate 200, a water path switching assembly 300 and a water outlet nozzle assembly 400; the shower body 100 is provided with a water inlet channel 110, a first water cavity 120, a second water cavity 130 and a third water cavity 140, the water inlet channel 110 can selectively communicate with the first water cavity 120, the second water cavity 130 and the third water cavity 140; the water distribution plate 200 is located between the second water cavity 130 and the third water cavity 140, and is provided with a water passing hole 210; the water path switching assembly 300 is movably arranged in the first water cavity 120, and can make the first water cavity 120 intermittently communicate with the second water cavity 130 and the third water cavity 140 respectively; the water outlet nozzle assembly 400 is arranged on the shower body 100, and communicates with the third water cavity 140 and the second water cavity 130 through the water passing hole 210. The shower body 100 is provided with three water cavities, and the water inlet channel 110 can selectively communicate with any one of the three water cavities, one water cavity corresponds to one water outlet mode, and the three water cavities all communicate with the water outlet nozzle assembly 400, that is, the three water cavities all communicate with the hole to form different water spray styles, accordingly, the diversity of the water outlet of the shower head 10 can be improved on the premise of the same water outlet hole.

Specifically, the impeller 310 and the internal gear 320 are connected through the eccentric shaft 330, the internal gear 320 can rotate around the eccentric shaft 330 as the rotation center, the waterway switching assembly 300 adopts the rotating mode to make the opening 321 of the internal gear 320 intermittently communicate with the first water passage 122a or the second water passage 122b.

[0080] Further, the waterway switching assembly 300 further comprises an internal gear ring 340, the internal gear ring 340 is arranged on the groove wall of the second sink groove 122, and the internal gear 320 is engaged with the internal gear ring 340 with a small tooth difference. Specifically, the internal gear 320 is engaged with the internal gear ring 340 with a small tooth difference, the number of teeth of the internal gear ring 340 is greater than that of the internal gear 320, the internal gear ring 340 can be arranged on the groove wall of the second sink groove 122 independently or can be integrally formed with the groove wall of the second sink groove 122, and the internal gear 320 rotates relative to the internal gear ring 340. The rotation center of the internal gear 320 is arranged in a position different from the center of the internal gear 320. In this way, the rotation of the internal gear 320 can be decelerated, and the deceleration principle can refer to the small-tooth-difference deceleration mechanism, which will not be described in detail.

[0081] The rotation of the internal gear 320 is decelerated, which is mainly considered that when the water in the water inlet channel 110 enters the first water cavity 120, the impeller 310 will rotate rapidly. If the internal gear 320 is driven to rotate synchronously by the impeller 310 with a high rotating speed, the water flow effect of the dancing water flow mode of the shower head 10 is not obvious, and the user experience is not high. To avoid the above problems, the rotation of the internal gear 320 is optionally decelerated by the small-tooth-difference and the arrangement of the rotation center of the internal gear 320 in a position different from the center of the internal gear 320, so that the user can obviously see and feel the water flow effect of the dancing water flow mode.

[0082] Please continue to refer to Figures 3 to 6 In this case, when the internal gear 320 rotates relative to the internal gear ring 340, the internal gear 320 may have the phenomenon of tooth jamming, thereby affecting the water flow of the shower water cavity. In view of this, to solve the problem, the teeth of the internal gear 320 and the teeth of the internal gear ring 340 are optionally arranged in a circular arc tooth shape, so that the internal gear 320 can rotate smoothly when it rotates relative to the internal gear ring 340, and the problem of tooth jamming is avoided.

[0083] Please refer to Figure 4 and Figure 5In an embodiment, the opening 321 extends along the circumference of the inner gear 320, and a reinforcing rib 321a is arranged in the opening 321. Specifically, the inner gear 320 is arranged in a disc shape, the teeth are arranged on the circumferential side of the inner gear 320, and the opening 321 is arranged on the body of the inner gear 320 and extends along the circumference of the inner gear 320, and the size of the opening 321 is about half of the body of the inner gear 320. In use, the inner gear 320 rotates for a long time, and therefore, in order to improve the structural strength at the opening 321, the reinforcing rib 321a is arranged in the opening 321, and the structural strength at the opening 321 is enhanced by the reinforcing rib 321a, thereby increasing the overall structural strength of the inner gear 320.

[0084] Please refer to Figures 3 to 6 In an embodiment, a flow guide ring 350 is arranged on the outer circumference of the impeller 310, the flow guide ring 350 is connected with the groove bottom of the first sink 121, and a flow guide channel 351 is arranged on the flow guide ring 350 and inclined along the circumference of the flow guide ring 350. Specifically, the impeller 310 is arranged in the first sink 121, the circumference of the impeller 310 is provided with a plurality of blades, and the rotation of the impeller 310 is mainly achieved by the flow impact of the water flow on the blades, so that the kinetic energy of the water flow is transmitted to the impeller 310 to make the impeller 310 rotate. In order to ensure the rotation effect of the impeller 310, a flow guide ring 350 can be arranged on the outer circumference of the impeller 310, and a flow guide groove 121a is formed between the flow guide ring 350 and the inner wall of the first sink 121, and the flow guide groove 121a is arranged in an annular shape. The bottom of the flow guide groove 121a is provided with a drainage port 121b, when the water inlet channel 110 is communicated with the first water cavity 120, the water in the water inlet channel 110 flows into the flow guide groove 121a through the drainage port 121b, and because the flow guide channel 351 is arranged on the flow guide ring 350 and inclined along the circumference of the flow guide ring 350, the flow guide channel 351 is at the same height as the blades of the impeller 310, and the flow guide channel 351 is arranged opposite to the blades, the water in the flow guide groove 121a flows to the impeller 310 through the flow guide channel 351, and impacts the blades of the impeller 310 to make the impeller 310 rotate, thereby driving the inner gear 320 to rotate. The inclined arrangement of the flow guide channel 351 can further improve the impact effect of the water flow on the blades.

[0085] The number of the flow guide channels 351 can be one or multiple, in this embodiment, in order to ensure the impact effect on the blades of the impeller 310, the number of the flow guide channels 351 is set to multiple, and the multiple flow guide channels 351 are arranged at intervals along the circumference of the flow guide ring 350. Preferably, the number of the flow guide channels 351 is set to 3-5.

[0086] Please refer to Figures 3 to 7 , and Figures 10 to 17 In an embodiment, the shower head 10 further comprises a water distribution assembly 500 arranged in the water inlet channel 110, the water distribution assembly 500 having a first position, a second position and a third position, and the water distribution assembly 500 being switchable between the first position, the second position and the third position. Specifically, the water distribution assembly 500 can be used to deliver water in the water inlet channel 110 to the first water cavity 120, the second water cavity 130 or the third water cavity 140 respectively, wherein the water distribution assembly 500 has three positions corresponding to the three water cavities respectively, and each position is in communication with one water cavity.

[0087] Please refer to Figures 3 to 7 In an embodiment, the shower head 10 further comprises a third sink 600 and a fixing seat 700, the fixing seat 700 covering the third sink 600, the water distribution assembly 500 comprising a rotating sleeve 510 and a water distribution disc 520, the rotating sleeve 510 being rotatably arranged in the fixing seat 700, the water distribution disc 520 being arranged in the third sink 600, the water distribution disc 520 being connected with the rotating sleeve 510, and the rotating sleeve 510 being capable of driving the water distribution disc 520 to switch between the first position, the second position and the third position by rotating.

[0088] Specifically, the internal space of the third sink 600 forms a water distribution cavity, and the shape of the third sink 600 can be a rectangular sink, a circular sink, a rhombic sink or a sink of other shapes, which is not specifically limited. In the embodiment, the third sink 600 is arranged as a circular sink, and the third sink 600 can be arranged on the mounting seat 900, the third sink 600 having an upward opening, and the fixing seat 700 covering the third sink 600 to close the opening. The water distribution assembly 500 comprises a rotating sleeve 510 and a water distribution disc 520, the rotating sleeve 510 being rotatably arranged in the fixing seat 700, and the rotating sleeve 510 being fixedly connected with the water distribution disc 520, and the connection manner of the rotating sleeve 510 and the water distribution disc 520 is not limited.

[0089] Please refer to Figures 5 to 7Further, the water distribution disc 520 is provided with a switching port 521, and the third sink groove 600 is provided with a first communication port 610, a second communication port 620 and a third communication port 630. The first communication port 610 is in communication with the first water cavity 120, the second communication port 620 is in communication with the second water cavity 130, and the third communication port 630 is in communication with the third water cavity 140. When the water distribution disc 520 is in the first position, the switching port 521 is in communication with the first communication port 610. When the water distribution disc 520 is in the second position, the switching port 521 is in communication with the second communication port 620. When the water distribution disc 520 is in the third position, the switching port 521 is in communication with the third communication port 630.

[0090] Specifically, the rotating sleeve 510 can drive the water distribution disc 520 to switch among the first position, the second position and the third position by rotation. The water distribution disc 520 is disc-shaped, and the switching port 521 is formed on the water distribution disc 520 and is a port along the axis direction of the water distribution disc 520. The first communication port 610, the second communication port 620 and the third communication port 630 are formed on the groove bottom of the third sink groove 600, and are arranged along the circumferential direction of the groove bottom of the third sink groove 600. The number of the first communication port 610, the second communication port 620 and the third communication port 630 can be multiple, and multiple first communication ports 610, second communication ports 620 and third communication ports 630 are arranged along the circumferential direction of the groove bottom of the third sink groove 600. The number of the first communication port 610 is equal to the number of the second communication port 620 and the third communication port 630. Correspondingly, the number of the switching port 521 is also multiple, and multiple switching ports 521 are arranged along the circumferential direction of the water distribution disc 520. In order to avoid that the number of the first communication port 610, the second communication port 620 or the third communication port 630 is greater than the number of the switching port 521, so that an individual communication port cannot be used, the number of the switching port 521 should not be less than the number of the first communication port 610, the second communication port 620 or the third communication port 630.

[0091] Please refer to Figures 10 to 17When the water diversion disc 520 is in the first position, the switching port 521 is in communication with the first communication port 610, and the first communication port 610 is in communication with the first water cavity 120, so that the water inlet channel 110 is in communication with the first water cavity 120, and at this time, the shower head 10 is in a dancing water mode. The water in the water inlet channel 110 first flows into the flow guide groove 121a through the flow guide port 121b. Since the flow guide ring 350 is provided with the flow guide channel 351 which is arranged in an inclined manner along the circumferential direction of the flow guide ring 350, the flow guide channel 351 is at the same height as the blades of the impeller 310, and the flow guide channel 351 is arranged opposite to the blades, the water in the flow guide groove 121a flows to the impeller 310 through the flow guide channel 351, and impacts the blades of the impeller 310 to make the impeller 310 rotate, thereby driving the inner gear 320 to rotate. When the inner gear 320 rotates, the opening 321 on the inner gear 320 is intermittently in communication with the first water passing port 122a or the second water passing port 122b, so that the water in the first water cavity 120 is intermittently flowed to the second water cavity 130 or the third water cavity 140. The water entering the second water cavity 130 flows directly to the water outlet nozzle assembly 400 through the water passing hole 210, and then flows out through the water outlet nozzle assembly 400. The water entering the third water cavity 140 flows out through the water outlet nozzle assembly 400. In this dancing water mode, the water flow alternately flows out from the water outlet nozzle assembly 400 from the second water cavity 130 and the third water cavity 140. Since the water flow directions from the second water cavity 130 and the third water cavity 140 are different, the water flow from the second water cavity 130 is in a columnar shape, and the water flow from the third water cavity 140 is in a divergent granular shape. Therefore, in the dancing water mode, the water flow is in a combined mode of the columnar shape and the divergent granular shape, and the water flow effects of the two water flows correspond to the second water cavity 130 and the third water cavity 140. The two water flow states are intermittently switched to achieve the dancing effect. For example, when the shower head 10 is started to be used and is in the dancing water mode, the water flow is in the columnar shape in the odd seconds and is in the divergent granular shape in the even seconds since 0 second, and the two water flow states are intermittently switched to achieve the dancing effect.

[0092] Please continue to refer to Figures 10 to 17 When the water diversion disc 520 is in the second position, the second switching port 521 is in communication with the second communication port 620, and the second communication port 620 is in communication with the second water cavity 130, so that the water inlet channel 110 is in communication with the second water cavity 130, and at this time, the shower head 10 is in a shower water mode. After the water enters the second water cavity 130, it flows directly to the water outlet nozzle assembly 400 through the water passing hole 210, and then flows out through the water outlet nozzle assembly 400. In this mode, the water flow is in a columnar shape from the water outlet nozzle assembly 400.

[0093] Please continue to refer to Figures 10 to 17When the water distribution disc 520 is in the third position, the third switching port 521 is in communication with the third communication port 630, and the third communication port 630 is in communication with the third water cavity 140, so that the water inlet channel 110 is in communication with the third water cavity 140, and at this time, the shower head 10 is in the granular water flow mode. After the water enters the third water cavity 140, it flows out through the water outlet nozzle assembly 400. In this mode, the water flow is in the form of divergent granules from the water outlet nozzle assembly 400.

[0094] Please refer to Figure 2 、 Figures 10 to 17 In an embodiment, the water distribution assembly 500 further comprises a first sealing gasket 530, which is installed in the third sink groove 600 and below the water distribution disc 520. Specifically, the shape of the first sealing gasket 530 is adapted to the shape of the first communication port 610, the second communication port 620 and the third communication port 630, and the first sealing gasket 530 is installed between the water distribution disc 520 and the first communication port 610, the second communication port 620 and the third communication port 630, which can play a sealing role to prevent the water in the third sink groove 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 disc 520 and the first communication port 610, the second communication port 620 or the third communication port 630. Further, a second sealing gasket 550 can be provided on the outer periphery of the water distribution disc 520 to prevent the water in the third sink groove 600 from flowing out from the connection between the fixed seat 700 and the third sink groove 600.

[0095] It is considered here that the first sealing gasket 530 is below the water distribution disc 520, and when the water distribution disc 520 is displaced upward, the water distribution disc 520 cannot exert downward pressure on the first sealing gasket 530, and the first sealing gasket 530 can move upward due to the decrease in the pressure received and under the action of the buoyancy of the water, so as to fail to play a sealing role and possibly cause the water in the third sink groove 600 to flow into the first water cavity 120, the second water cavity 130 or the third water cavity 140 through the gap between the water distribution disc 520 and the first communication port 610, the second communication port 620 or the third communication port 630. To avoid this situation, specifically, the water distribution assembly 500 further comprises an elastic member 540, which is provided on the rotating sleeve 510 and connected with the water distribution disc 520. The elastic member 540 is a spring, which is installed in the rotating sleeve 510, one end of the spring is connected with the top wall inside the rotating sleeve 510, and the other end is connected with the water distribution disc 520. The spring can exert a downward elastic force on the water distribution disc 520, so that the water distribution disc 520 can press the first sealing gasket 530 tightly.

[0096] Please refer to Figures 3 to 8In an embodiment, the shower head 10 further comprises a driving mechanism 800 connected with the rotating sleeve 510 to drive the rotating sleeve 510 to rotate so as to switch the water distribution disc 520 between the first position, the second position and the third position. Specifically, the driving mechanism 800 is mainly used to drive the rotating sleeve 510. The type of the driving mechanism 800 is not specifically limited, which can comprise a worm, a worm wheel and a plurality of transmission gears 810; or the driving mechanism 800 can comprise a sprocket mechanism; or the driving mechanism 800 can comprise a connecting rod mechanism. In the embodiment, the driving mechanism 800 comprises a gear 810 connected with the rotating sleeve 510 and a rack 820 movably arranged on the fixed seat 700 and engaged with the gear 810. Specifically, the gear 810 is fixedly connected with the rotating sleeve 510, the rack 820 is engaged with the gear 810, when the rack 820 moves, the gear 810 can be driven to rotate, the rotating of the gear 810 drives the rotating sleeve 510 to rotate, the rotating of the rotating sleeve 510 drives the water distribution disc 520 to rotate, so as to switch the water distribution disc 520 between the first position, the second position and the third position.

[0097] Please refer to Figure 1 , Figure 2 , Figures 10 to 17 Further, the driving mechanism 800 further comprises a push rod 830 connected with the rack 820 and a push button 840 arranged on the push rod 830. The push button 840 is exposed on the outer surface of the shell 11, when a user needs to switch the water outlet mode of the shower head 10, only needs to push the push button 840 with hands to realize the switching of the three water outlet modes, which is convenient and fast and is convenient for the user to operate.

[0098] Please refer to Figure 4 and Figure 8 In an embodiment, the fixed seat 700 is provided with an elastic limiting column 710, the rack 820 is provided with a first clamping groove 821, a second clamping groove 822 and a third clamping groove 823, when the water distribution disc 520 is in the first position, the elastic limiting column 710 extends into the first clamping groove 821; when the water distribution disc 520 is in the second position, the elastic limiting column 710 extends into the second clamping groove 822; when the water distribution disc 520 is in the third position, the elastic limiting column 710 extends into the third clamping groove 823.

[0099] Specifically, the fixing seat 700 is provided with a groove below the rack 820, the elastic limiting column 710 is installed in the groove, the elastic limiting column 710 includes a spring and a limiting head, the spring is arranged in the groove, the limiting head is connected with the spring, the limiting head abuts against the lower end surface of the rack 820, the first clamping groove 821, the second clamping groove 822 and the third clamping groove 823 are opened in the lower end surface of the rack 820. The limiting head and the rack 820 are both made of metal material, when the rack 820 moves, the elastic limiting column 710 will slide into the first clamping groove 821, the second clamping groove 822 or the third clamping groove 823 along with the movement of the rack 820, wherein, when the water distribution disc 520 is in the first position, the elastic limiting column 710 extends into the first clamping groove 821; when the water distribution disc 520 is in the second position, the elastic limiting column 710 extends into the second clamping groove 822; when the water distribution disc 520 is in the third position, the elastic limiting column 710 extends into the third clamping groove 823. When the elastic limiting column 710 extends into the first clamping groove 821, the second clamping groove 822 or the third clamping groove 823, because the limiting head and the rack 820 are both made of metal material, the limiting head and the first clamping groove 821, the second clamping groove 822 or the third clamping groove 823 will emit a sound when they contact, the user can hear the sound when using, so that the user can clearly know that the water outlet mode of the shower head 10 has been switched to the right position. At the same time, the first clamping groove 821, the second clamping groove 822 and the third clamping groove 823 also limit the displacement of the rack 820, preventing the user from changing the water outlet mode of the shower head 10 due to accidental touch of the push button 840 when using the shower head 10.

[0100] Please refer to Figures 10 to 21 In an embodiment, the water outlet nozzle assembly 400 includes a water outlet nozzle 410 and a water inlet seat 420, the water outlet nozzle 410 and the water inlet seat 420 are connected, the shower body 100 further includes a shell 11 and a panel 12, the shell 11 is connected with the panel 12, the water outlet nozzle 410 passes through the panel 12, the top of the water inlet seat 420 communicates with the water passing hole 210, and the side wall of the water inlet seat 420 is provided with a water inlet hole 423.

[0101] Specifically, the shell 11 and the panel 12 enclose to form an installation cavity for installing other components of the shower head 10, and a mounting seat 900 is installed in the installation cavity, the mounting seat 900 is enclosed with the panel 12 to form a first water cavity 120, a second water cavity 130 and a third water cavity 140. The water outlet nozzle assembly 400 includes a water outlet nozzle 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 with the water outlet nozzle 410 and the water outlet nozzle 410 penetrates through the panel 12, and the water in 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 nozzle 410. The top of the water inlet seat 420 communicates with the water passing hole 210, and the water in the second water cavity 130 mainly flows into the water inlet seat 420 from the top of the water inlet seat 420 through the water passing hole 210 and then flows out through the water outlet nozzle 410. To avoid the water in the second water cavity 130 flowing into the third water cavity 140 when the water flows from the water passing hole 210 to the water inlet seat 420, the top of the water inlet seat 420 can be abutted with 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, and the water in the third water cavity 140 mainly flows into the water inlet seat 420 from the side of the water inlet seat 420 through the water inlet hole 423 and then flows out through the water outlet nozzle 410.

[0102] Please refer to Figure 23 Further, the water inlet seat 420 includes a body part 421 and an extension part 422, the extension part 422 is connected with the side wall of the body part 421, and the water inlet hole 423 is provided in the extension part 422. The cross section of the body part 421 is circular, and the extension part 422 is two extension sections extending outward from the side wall of the body part 421, and the water inlet hole 423 is formed between the two extension sections. Of course, in other embodiments, the cross section of the body part 421 can be square, rhombus or other shapes, which are not limited specifically.

[0103] It should be noted that the inner wall of the body part 421 is arranged in a necked manner from the top of the body part 421 to the water outlet nozzle 410. Specifically, the inner wall of the body part 421 is arranged in a substantially inverted conical shape. When water flows from the second water cavity 130 to the water inlet seat 420, the water flows in a vertical direction. When water flows from the third water cavity 140 to the water inlet seat 420, the water flows in a horizontal direction. The water flow directions of the two water cavities are different. When water flows from the second water cavity 130 to the water inlet seat 420, the water directly flows to the water outlet nozzle 410 or the inner wall surface of the body part 421. The water has a small resistance and directly flows out of the water outlet nozzle 410 along the inner wall surface of the body part 421. At this time, the water spray is in a columnar shape. When water flows from the third water cavity 140 to the water inlet seat 420, the water flows to the inner wall surface of the body part 421. The water has a large resistance and does not directly flow out of the water outlet nozzle 410 along the inner wall surface of the body part 421. Instead, the water rotates along the inner wall surface of the body part 421 and is thrown out of the water outlet nozzle 410. At this time, the water spray is in a divergent granular shape.

[0104] Please refer to Figure 19 and Figure 23 In an embodiment, the water passing hole 210 is coaxially arranged with the water outlet nozzle 410, or the radius of the body part 421 is R, the distance between the axis of the water passing hole 210 and the axis of the water outlet nozzle 410 is L, and R≥L>0. Specifically, to ensure that the water spray is in a columnar shape when water flows from the second water cavity 130 to the water inlet seat 420 through the water passing hole 210 and flows out of the water outlet nozzle 410, the water passing hole 210 is coaxially arranged with the water outlet nozzle 410. Considering the stability of the water spray, preferably, the axis of the water passing hole 210 is located within the radius range of the body part 421, that is, the radius of the body part 421 is R, the distance between the axis of the water passing hole 210 and the axis of the water outlet nozzle 410 is L, and R≥L>0.

[0105] Please refer to Figure 23 In another embodiment, the radius of the body part 421 is R, the distance between the inlet end of the water inlet hole 423 and the axis of the water outlet nozzle 410 is D, the distance between the axis of the water passing hole 210 and the axis of the water outlet nozzle 410 is L, and 0.9D≥L>R. Specifically, when the distance L between the axis of the water passing hole 210 and the axis of the water outlet nozzle 410 satisfies 0.9D≥L>R, at this time, the water in the second water cavity 130 enters the water inlet hole 423 through the water passing hole 210, and then flows to the water inlet seat 420 through the water inlet hole 423 and flows out of the water outlet nozzle 410. Compared with the inlet end of the water inlet hole 423, the water passing hole 210 is closer to the axis of the water outlet nozzle 410, and the resistance of the water flow to the inner wall of the water inlet seat 420 is smaller. At this time, the water spray is in a granular water with a small granular scattering range (see Figure 21) ; when the water in the third water cavity 140 flows into the water inlet seat 420 through the water inlet hole 423, the water flow has a large resistance when flowing to the inner wall of the water inlet seat 420 because the inlet end of the water inlet hole 423 is far away from the axis of the water outlet nozzle 410, at this time, the water spray mode is the granular water with a large granular scattering range (see Figure 20 ).
