[0002] Existing showers with spray gun functions generally switch the water outlet channels by driving the valve core structure to move axially, thereby switching between the shower water outlet function and the spray gun water outlet function. In order to meet the requirements of a short valve core structure stroke and easy driving, the upstream side of different water outlet channels needs to be located within the stroke range of the valve core structure, resulting in a relatively fixed position of the upstream side of the water outlet channel relative to the valve core structure, which is not conducive to innovative design of the layout of the water outlet channel on the shower head and the direction of the channel.

[0047] Please combine Figures 1 to 4 , Figure 6 , Fig. 9 , Figures 11 to 14 and Figure 17 to Figure 21bThe shower provided by the embodiment of the present disclosure is now described. The shower includes a shell mechanism 10, a surface shell mechanism 20, a spray gun mechanism 30 and a water channel switching device 40. The shell mechanism 10 is provided with a water supply channel 100. The surface shell mechanism 20 is arranged on the shell mechanism 10 and is provided with a shower flow channel 200, and the shower flow channel 200 can guide water to be discharged from the surface shell mechanism 20. The spray gun mechanism 30 is arranged on the shell mechanism 10 and is provided with a spray gun flow channel 300, and the spray gun flow channel 300 can guide water to be discharged from the spray gun mechanism 30. The spray gun mechanism 30 includes a water inlet end 31, a nozzle 32, and a pipe 33 located between the water inlet end 31 and the nozzle 32. The spray gun flow channel 300 passes through the water inlet end 31, the pipe 33 and the nozzle 32 in sequence.

[0048] The water path switching device 40 is arranged on the housing mechanism 10. The water path switching device 40 includes a housing 41, a swinging assembly 42 and a driving mechanism 43. The housing 41 is provided with a cavity 400 and a water inlet channel 401, a first water outlet channel 402 and a second water outlet channel 403 connected to the cavity 400. The first water outlet channel 402 has a first upstream side 4021 connected to the cavity 400, and the second water outlet channel 403 has a second upstream side 4031 connected to the cavity 400. The swinging assembly 42 is mounted on the cavity 400 and is rotatably connected to the housing 41. The water inlet channel 401 is connected to the water supply channel 100, the first water outlet channel 402 is connected to the shower channel 200, and the second water outlet channel 403 is connected to the spray gun channel 300. The driving mechanism 43 can be movably mounted on the housing 41, and the driving mechanism 43 is configured to drive the swing assembly 42 to swing relative to the housing 41 to seal the first upstream side 4021 or the second upstream side 4031. The housing 41 may include a plurality of split structures to facilitate opening the cavity 400 and installing the swing assembly 42. After the swing assembly 42 is installed, the split structures can be fixedly connected by welding or other methods to ensure the strength of the housing 41.

[0049] like Figure 18 to Figure 21b As shown, water sequentially enters the cavity 400 through the water supply channel 100 and the water inlet channel 401. When the swing assembly 42 seals the second upstream side 4031, water enters the first water outlet channel 402 from the first upstream side 4021 and enters the shower channel 200, and is discharged from the shell mechanism 20, realizing the shower water outlet function; when the swing assembly 42 seals the first upstream side 4021, water enters the second water outlet channel 403 from the second upstream side 4031 and enters the spray gun channel 300, and is discharged from the spray gun mechanism 30, realizing the spray gun water outlet function.

[0050] The shower head is provided with a connection part 11 connected to the water supply assembly. The connection part 11 can be connected to the water supply assembly by means of, but not limited to, threaded connection, plug connection, snap connection or welding. The water supply assembly is configured to provide water to the water supply channel 100. The water supply assembly can be, but not limited to, a manually controlled or electrically controlled valve structure, and the water supply channel 100 is connected or disconnected from the water source by opening or closing the water supply assembly. The water includes, but is not limited to, clean water or pure water from a municipal water network.

[0051] In summary, the implementation of the disclosed embodiment will have the following beneficial effects: the water channel switching device 40 of the above scheme is applied to the shower head. In addition to enabling the water channel switching device 40 to have an excellent switching performance between the shower head water outlet function and the spray gun water outlet function, it can also ensure that the position of the upstream side of the water outlet flow channel is more flexible, so as to facilitate the innovative design of the layout of the water outlet flow channel on the shower head, the flow channel direction, etc. Specifically, the water channel switching device 40 includes a shell 41 provided with a cavity 400, a swing assembly 42 installed in the cavity 400 and rotatably connected to the shell 41, and a driving mechanism 43 movably installed on the shell 41. Among them, the shell 41 is provided with a water inlet flow channel 401 connected to the cavity 400, a first water outlet flow channel 402 and a second water outlet flow channel 403, the first water outlet flow channel 402 has a first upstream side 4021 connected to the cavity 400, and the second water outlet flow channel 403 has a second upstream side 4031 connected to the cavity 400. The driving mechanism 43 is configured to drive the swing assembly 42 to swing relative to the housing 41 to seal the first upstream side 4021 or the second upstream side 4031. In this way, the swing assembly 42 can be designed according to the positions of the first upstream side 4021 and the second upstream side 4031 to ensure the switching effect of the water outlet flow channel, so that the positions of the first upstream side 4021 and the second upstream side 4031 can be more flexible to match the layout of the water outlet flow channel on the shower head, the flow channel direction and other innovative designs.

[0052] In an exemplary embodiment, please combine Figure 4 , Figure 7 , Fig.10 , Figure 19 to Figure 21b The swing assembly 42 includes a swing member 421, a first seal 422 and a second seal 423. The swing member 421 is rotationally connected to the shell 41. The first seal 422 and the second seal 423 are located on both sides of the rotation axis of the swing member 421 and are arranged on the swing member 421, so that when the first seal 422 is close to the first upstream side 4021, the second seal 423 can be away from the second upstream side 4031; and when the first seal 422 is away from the first upstream side 4021, the second seal 423 can be close to the second upstream side 4031, so as to seal one of the first upstream side 4021 and the second upstream side 4031, and the other is connected with the water inlet channel 401.

[0053] During the swinging of the swinging member 421 relative to the housing 41, the first seal 422 can be fitted with the housing 41 to seal the first upstream side 4021, or the second seal 423 can be fitted with the housing 41 to seal the second upstream side 4031. In this way, by setting the first seal 422 and the second seal 423, the elastic deformation ability of the first seal 422 and the second seal 423 can be utilized to better fit with the housing 41, thereby increasing the connection area with the housing 41, and then improving the sealing performance of the first upstream side 4021 and the second upstream side 4031. The first seal 422 and the second seal 423 are made of an elastomeric material. The size and shape of the first seal 422 and the second seal 423 match the shape and radial size of the first upstream side 4021 and the second upstream side 4031 to ensure the sealing performance.

[0054] In an exemplary embodiment, please combine Figure 7 , Fig.10 , Fig.20a , Fig.20b , Fig.21a and Figure 21b , the swinging member 421 is provided with a first mounting groove 500 and a second mounting groove 600, the first sealing member 422 is installed in the first mounting groove 500 and partially exposed from the swinging member 421, and the second sealing member 423 is installed in the second mounting groove 600 and partially exposed from the swinging member 421. In this way, the connection area between the first sealing member 422 and the swinging member 421 can be increased by the provision of the first mounting groove 500, and the connection stability between the first sealing member 422 and the swinging member 421 can be ensured. Similarly, the connection area between the second sealing member 423 and the swinging member 421 can be increased by the provision of the second mounting groove 600, and the connection stability between the second sealing member 423 and the swinging member 421 can be ensured. The first sealing member 422 and the second sealing member 423 are both exposed from the swinging member 421, so as to be conveniently fitted with the housing 41 to seal the first upstream side 4021 and the second upstream side 4031.

[0055] In an exemplary embodiment, please combine Figure 7 and Fig.10The first seal 422 is provided with a first clamping portion 4221, the second seal 423 is provided with a second clamping portion 4231, the swinging member 421 is provided with a third clamping portion 4211 and a fourth clamping portion 4212, the third clamping portion 4211 is located in the first mounting groove 500 and can be clamped and matched with the first clamping portion 4221, and the fourth clamping portion 4212 is located in the second mounting groove 600 and can be clamped and matched with the second clamping portion 4231. In this way, the clamping and matching of the first clamping portion 4221 and the third clamping portion 4211 can facilitate the rapid installation between the first seal 422 and the swinging member 421, and further improve the connection stability. Similarly, the clamping and matching of the second clamping portion 4231 and the fourth clamping portion 4212 can facilitate the rapid installation between the second seal 423 and the swinging member 421, and further improve the connection stability. In the embodiment of the present disclosure, one of the first clamping portion 4221 and the third clamping portion 4211 is a protruding structure, and the other has a groove structure, and the protruding structure can be received in the groove structure to achieve the clamping fit between the first clamping portion 4221 and the third clamping portion 4211. One of the second clamping portion 4231 and the fourth clamping portion 4212 is a protruding structure, and the other has a groove structure, and the protruding structure can be received in the groove structure to achieve the clamping fit between the second clamping portion 4231 and the fourth clamping portion 4212.

[0056] In an exemplary embodiment, please combine Fig.10 , Fig.20a , Fig.20b , Fig.21a and Figure 21b The swing member 421 includes a rotating shaft 4213 and a first support arm 4214 and a second support arm 4215 disposed on both sides of the rotating shaft 4213. The plane where the first support arm 4214 is located and the plane where the second support arm 4215 is located are not coplanar and are both parallel to the rotating axis of the swing member 421. In this way, the first support arm 4214, the second support arm 4215 and the rotating shaft 4213 can form a dihedral structure as a whole, and the dihedral angle of the dihedral structure is not 0° and 180°, so that there can be a certain angle between the first support arm 4214 and the second support arm 4215, thereby improving the strength of the swing member 421 and improving the stability of the sealing of the first upstream side 4021 and the second upstream side 4031. The first seal 422 is disposed on the first support arm 4214, and the second seal 423 is disposed on the second support arm 4215.

[0057] In the embodiment of the present disclosure, the first upstream side 4021 and the second upstream side 4031 are located on the same side of the swing member 421 and are coplanar (assuming that the plane is the first plane). The above-mentioned setting of the swing member 421 can also enable the first seal 422 to be directly opposite to the first upstream side 4021 when the first support arm 4214 is close to the first upstream side 4021 and parallel to the first plane, thereby improving the sealing stability. At this time, the second support arm 4215 is away from the second upstream side 4031, and the second support arm 4215 is inclined relative to the first plane, thereby ensuring that there is a larger space between the second seal 423 and the second upstream side 4031, thereby facilitating water to enter the second upstream side 4031. Similarly, the above-mentioned setting of the swing member 421 can also enable the second seal 423 to be directly opposite the second upstream side 4031 when the second support arm 4215 is close to the second upstream side 4031 and parallel to the first plane, thereby improving the sealing stability. At this time, the first support arm 4214 is away from the first upstream side 4021, and the first support arm 4214 is inclined relative to the first plane, thereby ensuring that there is a larger space between the first seal 422 and the first upstream side 4021, thereby facilitating water to enter the first upstream side 4021.

[0058] In an exemplary embodiment, please combine Figure 2 , Figure 4 , Fig.20a , Fig.20b , Fig.21a and Figure 21b The driving mechanism 43 includes a pressing component 431 and a first reset component 432. The pressing component 431 is configured to move relative to the housing 41 in a first direction under the action of an external force to drive the swing component 42 to swing, seal one of the first upstream side 4021 and the second upstream side 4031, and make the first reset component 432 generate a driving force for resetting the swing component 42. The first reset component 432 is configured to drive the swing component 42 to reset after the external force cancels the action on the pressing component 431, seal the other of the first upstream side 4021 and the second upstream side 4031, and drive the pressing component 431 to reset through the swing component 42. In this way, the first reset component 432 can drive the swing component 42 and the pressing component 431 to reset, so as to facilitate the function switching again, and make one of the functions of the shower head water discharge and the spray gun water discharge become the initial state of the shower. In the embodiment of the present disclosure, the initial state of the shower is the shower head water discharge. When the shower head needs to be switched to a spray gun, the pressing component 431 can be used to drive the swing component 42 to swing. Figure 4 The first reset member 432 is a spiral spring. It can be understood that in other embodiments, the first reset member 432 can also be a magnetic member, which generates a magnetic force to drive the swing assembly 42 to reset.

[0059] In an exemplary embodiment, please combine Fig.20a , Fig.20b , Fig.21a and Figure 21b , the first reset member 432 is a coil spring, the housing 41 is provided with a first positioning portion 411, the swing assembly 42 is provided with a second positioning portion 424, the first reset member 432 is clamped between the first positioning portion 411 and the second positioning portion 424, and is connected to the first positioning portion 411 and the second positioning portion 424 respectively. In this way, the position stability of the first reset member 432 can be ensured by the provision of the first positioning portion 411 and the second positioning portion 424, thereby ensuring the stability of the reset of the swing assembly 42. In the embodiment of the present disclosure, the first positioning portion 411 and the second positioning portion 424 are both groove structures. It can be understood that in other embodiments, at least one of the first positioning portion 411 and the second positioning portion 424 can also be a columnar structure.

[0060] In an exemplary embodiment, please combine Figure 4 , Figure 7 , Fig.20a , Fig.20b , Fig.21a and Figure 21b A first transmission part 425 is provided on the swing component 42, and a second transmission part 4311 is provided on the pressing component 431. The second transmission part 4311 and the first transmission part 425 are arranged relatively to each other along the first direction, so that when one of the first transmission part 425 and the second transmission part 4311 moves toward the other, it can drive the other to move synchronously, and when one of the first transmission part 425 and the second transmission part 4311 moves away from the other, it can avoid driving the other to move synchronously, that is, the first transmission part 425 and the second transmission part 4311 only restrict each other in the first direction and when they move relative to each other, so as to be able to drive each other.

[0061] When the pressing assembly 431 moves relative to the housing 41 along the first direction under the action of an external force, the second transmission part 4311 can abut against the first transmission part 425 to drive the swing assembly 42 to swing, thereby sealing one of the first upstream side 4021 and the second upstream side 4031, and causing the first reset member 432 to generate a driving force for restoring the swing assembly 42;

[0062] When the first reset member 432 drives the swing assembly 42 to reset, the first transmission part 425 can abut against the second transmission part 4311 to drive the pressing assembly 431 to reset, and the swing assembly 42 can seal the other of the first upstream side 4021 and the second upstream side 4031 after reset.

[0063] In this way, the arrangement of the first transmission part 425 and the second transmission part 4311 can ensure the effective transmission of the driving force between the swing assembly 42 and the pressing assembly 431. In addition, when the first reset member 432 drives the swing assembly 42 to reset, and the first transmission part 425 is subject to a large resistance from the second transmission part 4311, the non-fixed connection between the first transmission part 425 and the second transmission part 4311 can be fine-tuned under the driving of the first reset member 432 on the swing assembly 42, thereby reducing the risk of the swing assembly 42 getting stuck during the reset process. In the disclosed embodiment, the first transmission part 425 is a protruding structure protruding from the swing assembly 42; the second transmission part 4311 is a protruding structure protruding from the pressing assembly 431, and the protruding size and shape of the first transmission part 425 and the second transmission part 4311 can be designed according to factors such as the position between the swing assembly 42 and the pressing assembly 431 and the structure that needs to be avoided during the movement of the first transmission part 425 and the second transmission part 4311.

[0064] In an exemplary embodiment, please combine Figure 4 , Figure 7 , Fig.20a , Fig.20b , Fig.21a and Figure 21b , the water channel switching device 40 also includes a second reset member 44. The pressing assembly 431 is also configured to move relative to the shell 41 in the first direction under the action of an external force, and the second reset member 44 generates a driving force for resetting the pressing assembly 431. The second reset member 44 is configured to drive the pressing assembly 431 to reset after the external force cancels the action on the pressing assembly 431. In this way, the setting of the second reset member 44 can ensure the stable reset of the pressing assembly 431, and can reduce the resistance of the second transmission part 4311 to the reset of the swing assembly 42, so that the reset of the pressing assembly 431 and the swing assembly 42 can be carried out synchronously. In the embodiment of the present disclosure, the second reset member 44 is a coil spring. It can be understood that in other embodiments, the second reset member 44 can also be a magnetic member, which drives the pressing assembly 431 to reset by generating a magnetic force.

[0065] In an exemplary embodiment, please combine Figure 4 , Fig.20a , Fig.20b , Fig.21a and Figure 21bThe pressing component 431 includes a pressing member 4312 and a transmission member 4313. The pressing member 4312 is exposed to the housing 41. In the embodiment of the present disclosure, the pressing member 4312 is also exposed to the housing mechanism 10 to facilitate finger driving. The transmission member 4313 is connected to the pressing member 4312 and cooperates with the housing 41 guide, so that the directional accuracy of the pressing component 431 relative to the housing 41 can be further improved, thereby ensuring the transmission stability between the pressing component 431 and the swinging component 42. The pressing member 4312 is configured to be able to move along the first direction under the action of an external force, so as to drive the swinging component 42 to swing through the transmission member 4313, seal one of the first upstream side 4021 and the second upstream side 4031, and make the first reset member 432 generate a driving force for resetting the swinging component 42 and the second reset member 44 generate a driving force for resetting the pressing component 431. In the embodiment of the present disclosure, the radial dimension of the pressing member 4312 is large to increase the pressing surface area that cooperates with the finger and improve the comfort of finger pressing. The radial dimension of the transmission member 4313 is small, so that the contact area between the transmission member 4313 and the housing 41 is small, thereby reducing the movement resistance.

[0066] In an exemplary embodiment, please combine Figure 4 , Fig.20a , Fig.20b , Fig.21a and Figure 21b , the second reset member 44 is a coil spring, the housing 41 is provided with a third positioning portion 412, the transmission member 4313 is provided with a fourth positioning portion 43131, the second reset member 44 is clamped between the third positioning portion 412 and the fourth positioning portion 43131, and is connected to the third positioning portion 412 and the fourth positioning portion 43131 respectively. In this way, the position stability of the second reset member 44 can be ensured by the provision of the third positioning portion 412 and the fourth positioning portion 43131, thereby ensuring the stability of the reset of the pressing assembly 431. In the embodiment of the present disclosure, the third positioning portion 412 has a groove structure and a columnar structure is accommodated in the groove structure to limit both the circumferential inner side and the circumferential outer side of the first reset member 432, and the fourth positioning portion 43131 is a groove structure.

In the disclosed embodiment, the sealing structure 45 is made of an elastomer material.

[0068] In an exemplary embodiment, please combine Figure 4 , Fig.20a , Fig.20b , Fig.21a and Figure 21b The housing 41 is provided with a groove 700, and the waterway switching device 40 further includes a pressure cover 46, which is sleeved on the transmission member 4313 and connected to the housing 41 to press the sealing structure 45 into the groove 700. In this way, the connection stability between the sealing structure 45 and the housing 41 can be further improved by the arrangement of the groove 700 and the pressure cover 46, so as to prevent the sealing structure 45 from being separated from the housing 41 when the transmission member 4313 moves relative to the housing 41.

[0069] In an exemplary embodiment, please combine Figure 3 , Figure 6 and Figures 11 to 13 The shell mechanism 20 is provided with a water dividing end surface 21 and a plurality of water outlet areas 22. Water can be discharged from different water outlet areas 22, realizing different water outlet functions and forming different water outlet effects to meet different use requirements of users.

[0070] The shower flow channel 200 includes a plurality of branches 201, each of which corresponds to each water outlet area 22 and runs between the corresponding water outlet area 22 and the water dividing end surface 21. That is, each water outlet area 22 corresponds to a branch 201 that can communicate with the first water outlet flow channel 402 to guide water to the corresponding water outlet area 22 and discharge it.

[0071] The shell mechanism 20 can rotate relative to the outer shell mechanism 10 to connect the first water outlet channel 402 with one of the multiple branches 201, or disconnect the first water outlet channel 402 from all the multiple branches 201. By rotating the shell mechanism 20 relative to the outer shell mechanism 10, the connection state between the first water outlet channel 402 and the multiple branches 201 can be changed, and then different water outlet areas 22 can be switched to discharge water or multiple water outlet areas 22 can be closed at the same time according to specific usage requirements.

[0072] In an exemplary embodiment, please combine Figure 3 , Figure 5 , Figure 8 and Figures 11 to 13 A first rotating shaft 12 is provided on the outer shell mechanism 10, and a second rotating shaft 23 is provided on the surface shell mechanism 20. The first rotating shaft 12 and the second rotating shaft 23 are coaxially arranged and one is sleeved on the other to realize the rotational connection between the first rotating shaft 12 and the second rotating shaft 23, so as to increase the overlapping position between the first rotating shaft 12 and the second rotating shaft 23, increase the connection area, and improve the rotational stability.

[0073] One of the first rotating shaft 12 and the second rotating shaft 23 has a positioning groove 800, and the other has a positioning shaft 24. The first rotating shaft 12, the second rotating shaft 23, the positioning groove 800 and the positioning shaft 24 are coaxially arranged. The positioning shaft 24 is inserted into the positioning groove 800 and can rotate relative to the positioning groove 800 with the relative rotation of the first rotating shaft 12 and the second rotating shaft 23. In this way, the position accuracy between the first rotating shaft 12 and the second rotating shaft 23 can be improved by setting the positioning groove 800 and the positioning shaft 24, and the connection area between the first rotating shaft 12 and the second rotating shaft 23 can be further improved, and the rotation stability can be further improved. In the embodiment of the present disclosure, the first rotating shaft 12 and the second rotating shaft 23 are detachably connected, and a rotating circle 25 is arranged on one of the first rotating shaft 12 and the second rotating shaft 23. The rotating circle 25 is connected to the other of the first rotating shaft 12 and the second rotating shaft 23 through a retaining ring 251 to form a bearing structure between the first rotating shaft 12 and the second rotating shaft 23.

[0074] In an exemplary embodiment, please combine Figure 5 , Fig.12 , Fig.15 , Fig.16 and Fig.19 The shower head further includes a water outlet 50 and an elastic component 60. The water outlet 50 is arranged on the housing 41 and communicates with the first water outlet channel 402. The elastic component 60 is arranged on the water outlet 50. The elastic component 60 is provided with a through hole 900. The through hole 900 communicates with the first water outlet channel 402 through the water outlet 50. The elastic component 60 elastically abuts against the water-dividing end face 21. During the rotation of the shell mechanism 20 relative to the shell mechanism 10, the elastic component 60 can slide relative to the water-dividing end face 21. The through hole 900 can connect the first water outlet channel 402 with one of the multiple branches 201. In this way, during the rotation of the shell mechanism 20 relative to the shell mechanism 10, the elastic component 60 can always abut against the water-dividing end face 21, preventing water from being discharged from between the elastic component 60 and the water-dividing end face 21, so that the water has a certain flow direction under the restriction of the elastic component 60 and the water-dividing end face 21, ensuring that the water can stably flow into the corresponding branch 201.

[0075] The elastic component 60 includes a flexible member 61 and an elastic member 62. The flexible member 61 can elastically abut against the water-dividing end face 21. The flexible member 61 can better fit the water-dividing end face 21 by its own deformation, thereby improving the sealing performance between the elastic component 60 and the water-dividing end face 21. The water outlet member 50 is provided with an installation cavity 1000 connected to the first water outlet flow channel 402. The elastic member 62 is installed in the installation cavity 1000 and supported between the water outlet member 50 and the flexible member 61 to further improve the elastic abutment force of the flexible member 61 on the water-dividing end face 21, thereby further improving the sealing stability between the elastic component 60 and the water-dividing end face 21. The through hole 900 runs through the flexible member 61 and is connected to the first water outlet flow channel 402 through the installation cavity 1000. The flexible member 61 can be made of, but not limited to, rubber material. The elastic member 62 can be, but not limited to, a metal spring member and a plastic spring.

The central area 22a is located at the center of the surface shell mechanism 20, the inner circle area 22b is arranged around the periphery of the central area 22a, and the outer circle area 22c is arranged around the periphery of the inner circle area 22b.

[0077] The shell mechanism 20 includes a water outlet jacket 26, an inner frame 27, a water inlet plate 28 and a water separation plate 29 which are stacked in sequence. The water outlet area 22 is arranged on the water outlet jacket 26. The water separation end surface 21 is arranged on the water separation plate 29.

[0078] In order to increase the shower water discharge effect of the shower head, functional components can also be set on the surface shell mechanism 20. For example, in the embodiment of the present disclosure, the pulse component 70 is set at the position of the surface shell mechanism 20 corresponding to the central area 22a, so as to form pulse water discharge in the central area 22a. The pulse component 70 includes a water jet ring, an impeller, a swinging piece and a pin. The water jet ring is arranged on the inner frame 27 and is arranged around the impeller. The impeller is rotatably connected to the water outlet sleeve 26 through a pin. The swinging piece is arranged on the water outlet sleeve 26. The swinging piece is located between the water jet ring and the impeller and is arranged around the impeller. The branch 201 located in the central area 22a introduces water into the water jet ring, and the water jet ring forms a jet of water to impact the impeller to rotate. The impeller rotates to guide the water to the swinging piece, so that the swinging piece swings relative to the water outlet sleeve 26, and the water is discharged after passing through the swinging piece, forming a pulse water discharge.

[0079] The shower head also includes a decorative housing 80. The housing assembly is installed in the space enclosed by the decorative housing 80 and the housing mechanism 10. The water outlet area 22 is fitted with the decorative housing 80, and the decorative housing 80 has a hollow portion for the water outlet area 22 to discharge water.
