[0002] After the shower head has been used for a long time, minerals in the water, such as calcium ions and magnesium ions, tend to deposit at the water outlet to form scale, causing the water outlet to be blocked and affecting the water outlet effect of the shower head.

[0003] At present, in order to remove the scale on the water outlet hole, the prior art provides a cleaning piece in the shower head, and uses the water flow to impact the impeller to drive the cleaning piece to rotate, thereby cleaning the water outlet tray.

[0004] In the prior art shower, after the water is turned off, the impeller stops rotating and the cleaning part also stops rotating. At this time, water will remain in the cleaning part and the shower cavity. If the residual water is not discharged in time, scale will still be deposited, and the cleaning part will be in a closed and humid state for a long time, which is easy to breed bacteria. When the shower is used next time, the cleaning part will clean the scale again, resulting in the sprayed water flow carrying scale, bacteria, etc. for a long time, affecting the user's skin health.

The face shell assembly 11 includes a face cover 111 and a water outlet sleeve 112, and the water outlet sleeve 112 is arranged on one side of the face cover 111 to form a water outlet tray. The water outlet sleeve 112 and the face cover 111 can be integrally formed or connected by bonding or ultrasonic welding.

[0075] The water outlet hole 300 passes through the water outlet sleeve 112 and the face cover 111 in sequence. The housing 14 is covered on the side of the face cover 111 where the water outlet sleeve 112 is provided, and can be enclosed with the face cover 111 to form an installation space 400. The water inlet tray 12 is accommodated in the installation space 400, and is covered on the side of the face cover 111 where the water outlet sleeve 112 is provided, so as to be enclosed with the water outlet sleeve 112 to form a cavity 100.

The water inlet ball head 15 can be connected with the valve structure, and the valve structure is used to control whether water is supplied to the water inlet hole 200. The housing 14 can rotate relative to the water inlet ball head 15 to change the water outlet direction of the water outlet hole 300.

[0076] The impeller assembly 20 is received in the cavity 100 and supported by the housing mechanism 10. The impeller assembly 20 is configured to be driven to rotate in a first direction by water entering the cavity 100. In the disclosed embodiment, the impeller assembly 20 has a plurality of blades 21, which are arranged around the axial direction of the impeller assembly 20.

[0077] The cleaning member 30 is accommodated in the cavity 100 and connected to the impeller assembly 20. The cleaning member 30 is configured to rotate with the impeller assembly 20 to clean the water outlet tray. In the disclosed embodiment, the cleaning member 30 is a brush tray. The brush tray includes a frame 31 and a brush 32 disposed on the side of the frame 31 facing the water outlet tray. The brush 32 is distributed along the radial direction of the frame 31 to ensure that when the brush tray rotates, the brush 32 can sweep a larger area to ensure the cleaning effect of the water outlet tray and the effect of driving the residual water. It can be understood that in other embodiments, the cleaning member 30 can also be a scraper. The scraper may include a bracket and a scraper bar disposed on the side of the bracket facing the water outlet tray.

[0079] The impeller assembly 20 and the cleaning member 30 may be integrally formed, or connected by plugging, snapping, bonding, or ultrasonic welding.

[0080] The energy storage member 40 has an energy storage state and an energy release state. The energy storage member 40 is connected to the impeller assembly 20 and is configured to convert at least part of the kinetic energy of the impeller assembly 20 when rotating in a first direction into potential energy in the energy storage state, and to convert the potential energy into kinetic energy in the energy release state to drive the impeller assembly 20 to rotate in a second direction opposite to the first direction. The first direction and the second direction can be respectively Figure 5 and Fig.13 The directions indicated by arrows X and Y are the same. One of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction. The axial direction of the impeller assembly 20 is perpendicular to the plane where the first direction and the second direction are located.

[0081] In the process of switching from the energy storage state to the energy release state, the energy storage component 40 gradually expands; in the process of switching from the energy release state to the energy storage state, the energy storage component 40 gradually contracts. Alternatively, in the process of switching from the energy storage state to the energy release state, the energy storage component 40 gradually shortens; in the process of switching from the energy release state to the energy storage state, the energy storage component 40 gradually lengthens.

[0082] The energy storage member 40 may be an elastic energy storage member 40, which can convert the kinetic energy of the impeller assembly 20 into elastic potential energy. The elastic energy storage member 40 may be, but is not limited to, a spring, a coil spring, a torsion spring, a torsion spring, a gas spring, a rubber spring or an elastic rope.

[0083] In the disclosed embodiment, the elastic energy storage member 40 includes a coil spring 41. The coil spring 41 can continuously provide a large restoring force in a small space, so that more elastic potential energy can be stored and eventually converted into more kinetic energy, thereby providing more power for the rotation of the impeller assembly 20 and the cleaning member 30 along the second direction. At the same time, the provision of the coil spring 41 can save space and facilitate installation. In the process of switching from the energy storage state to the energy release state, the coil spring 41 gradually expands to release the elastic potential energy; in the process of switching from the energy release state to the energy storage state, the coil spring 41 gradually contracts to store the elastic potential energy.

[0084] It can be understood that in other embodiments, the energy storage member 40 includes an elastic rope. In the process of switching from the energy storage state to the energy release state, the elastic rope gradually shortens to release elastic potential energy; in the process of switching from the energy release state to the energy storage state, the elastic rope gradually lengthens to store elastic potential energy.

[0085] In the disclosed embodiment, the energy storage member 40 and the cleaning member 30 are sequentially arranged along the axial direction of the impeller assembly 20 and are connected to each other through the impeller assembly 20. The impeller assembly 20 and the energy storage member 40 are installed in the housing assembly 13.

For example, the housing assembly 13 may include a first housing 131 and a first cover 132. The energy storage member 40 is installed in the space enclosed by the first housing 131 and the first cover 132. The first housing 131 and the first cover 132 are detachably connected to facilitate the installation of the energy storage member 40. The first housing 131 and the first cover 132 are also respectively provided with hole structures to facilitate the connection of the impeller assembly 20 with the energy storage member 40 and the cleaning member 30. Sealing structures may also be provided between the impeller assembly 20 and the first housing 131 and the first cover 132 to prevent the energy storage component 40 from contacting water, thereby preventing the energy storage component 40 from being corroded by water and affecting energy storage and release of the energy storage component 40 .

[0086] The embodiment of the present disclosure includes a housing mechanism 10 having a cavity 100 and a water inlet hole 200, an impeller assembly 20 accommodated in the cavity 100 and supported by the housing mechanism 10, a cleaning member 30 accommodated in the cavity 100 and connected to the impeller assembly 20, and an energy storage member 40 having an energy storage state and an energy release state. Among them, the housing mechanism 10 has a water outlet tray provided with a water outlet hole 300. The energy storage member 40 is configured to convert at least part of the kinetic energy of the impeller assembly 20 when rotating in a first direction into potential energy in the energy storage state, and to convert the potential energy into kinetic energy in the energy release state, so as to drive the impeller assembly 20 to rotate in a second direction opposite to the first direction. After water is supplied to the cavity 100, the impeller assembly 20 rotates in the first direction under the action of the water pressure, converts at least part of the kinetic energy into potential energy, and drives the cleaning member 30 to rotate to clean the water outlet tray, so that the scale at the water outlet tray and the water outlet hole 300 becomes loose and is easy to be discharged from the water outlet hole 300 with water; after the water supply to the cavity 100 is stopped, the water pressure disappears, the energy storage member 40 releases the potential energy, drives the impeller assembly 20 to rotate in the second direction, drives the cleaning member 30 to rotate to clean the water outlet tray, spins off the residual water on the cleaning member 30 and destroys the water tension at the water outlet hole 300, so that the residual water in the shower head can be quickly discharged from the water outlet hole 300 under the drive of the cleaning member 30, so that there is no residual water in the shower head, it is not easy to scale, and the effect of descaling and preventing bacteria from breeding is achieved.

[0087] In the exemplary embodiment, please combine Figure 5 , Figure 6 , Figure 8 , Fig.11 , Fig.13 , Fig.14 and Fig.16 The impeller assembly 20 includes a rotating shaft 22 and an impeller 23. The rotating shaft 22 is rotatably connected to the housing mechanism 10. The cleaning member 30 is non-rotatably connected to the rotating shaft 22.

[0088] The energy storage member 40 includes a first end 42 and a second end 43, wherein the first end 42 is connected to the housing mechanism 10 in a non-rotatable manner, and the second end 43 is connected to the rotating shaft 22 in a non-rotatable manner. In this way, the first end 42 does not move with the rotation of the impeller assembly 20, and the second end 43 can rotate with the rotation of the impeller assembly 20, thereby converting at least part of the kinetic energy of the impeller assembly 20 when rotating in the first direction into potential energy.

[0089] In the disclosed embodiment, the energy storage member 40 includes a coil spring 41. The coil spring 41 is wound along a first direction. The first end 42 may be located at the end of the outer side of the winding path of the coil spring 41 or a position close to the end, and the second end 43 may be located at the end of the inner side of the winding path of the coil spring 41 or a position close to the end. The first end 42 and the housing assembly 13 may be connected by plugging, snapping or ultrasonic welding. The second end 43 and the rotating shaft 22 may be connected by plugging, snapping or ultrasonic welding. The first end 42 has a loop-like structure to form a space connected to the housing assembly 13 to increase the connection surface area between the first end 42 and the housing assembly 13 and improve the connection stability. The rotating shaft 22 is provided with a stop groove 600, and the second end 43 also has a loop-like structure, which can be plugged into the stop groove 600 through elastic deformation, and then the second end 43 returns to its original state to form a space matching the rotating shaft 22.

[0090] It can be understood that in other embodiments, the energy storage component 40 includes an elastic cord. The first end 42 and the second end 43 can be arranged at both ends of the elastic cord. And the first end 42 and the second end 43 are fixedly connected to the housing assembly 13 and the rotating shaft 22 respectively. In the process of switching from the energy release state to the energy storage state, the rotating shaft 22 can drive the second end 43 to rotate around the rotating shaft 22, and then the elastic cord is wound around the rotating shaft 22. Since the first end 42 is fixed to the housing assembly 13, the position of the first end 42 relative to the rotating shaft 22 remains unchanged, so that the elastic cord is gradually lengthened. In the process of switching from the energy storage state to the energy release state, the elastic cord releases energy and gradually shortens.

[0091] The impeller 23 is coaxially arranged on the rotating shaft 22, and is arranged to be driven by water entering the cavity 100 so that the impeller assembly 20 rotates in the first direction. The impeller 23 has a plurality of blades 21, and the plurality of blades 21 are arranged around the axial direction of the impeller assembly 20. The blades 21 can be straight. The blades 21 can also be in an arc shape bent along the second direction to increase the contact area with water and improve the efficiency of water driving the impeller assembly 20.

[0092] In an exemplary embodiment, there are multiple water outlet holes 300, and the flow area of ​​a part of the multiple water outlet holes 300 is larger than the flow area of ​​another part of the multiple water outlet holes 300. The larger flow area makes the space of the water outlet holes 300 larger, and the scale is easy to become loose under the action of the brush 32 and discharged from the water outlet holes 300, while the scale located in the water outlet holes 300 with smaller flow areas can be discharged from the water outlet holes 300 with larger flow areas together with other impurities under the action of the brush 32.

[0093] The inventor of the present disclosure has found that when the potential energy of the energy storage component 40 reaches a balance with the water pressure acting on the impeller assembly 20, the impeller assembly 20 stops rotating, and then the cleaning component 30 stops rotating. At this time, the water type of the water outlet 300 remains stable. When the water pressure is sometimes greater than the potential energy of the energy storage component 40, sometimes equal to the potential energy of the energy storage component 40, and sometimes less than the potential energy of the energy storage component 40, there is a situation of unstable water pressure. Since the potential energy of the energy storage component 40 and the water pressure acting on the impeller assembly 20 are in dynamic balance, when the water pressure is unstable, the energy storage component 40 switches back and forth between the energy storage state and the energy release state in a fluctuating manner, thereby driving the impeller assembly 20 to rotate in real time according to the change in water pressure, and then driving the cleaning component 30 to swing back and forth in a fluctuating manner along the first direction or the second direction, and sweeping across the water outlet 300, it is easy to destroy the water type of the water outlet 300 in real time, affecting the water outlet effect.

[0094] In the exemplary embodiment, please combine Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Figures 11 to 18 The shower head includes a non-return mechanism, which includes a first limit assembly and a second limit assembly 53, one of which is arranged on the impeller assembly 20, and the other of which is arranged on the housing mechanism 10. The non-return mechanism has a limit state and a separation state. In the limit state, the first limit assembly is in contact with the second limit assembly 53, and the non-return mechanism guides the impeller assembly 20 to rotate in the first direction all the time. In the separation state, the first limit assembly is separated from the second limit assembly 53. In this way, the setting of the non-return mechanism can make the first limit assembly contact with the second limit assembly 53 when water is supplied to the shower head, and then after the water pressure is reduced (the water supply to the shower head is not stopped), the impeller assembly 20 can be guided to rotate in the first direction all the time, and the impeller assembly 20 is prevented from rotating in the second direction, thereby preventing the energy storage component 40 from releasing potential energy to drive the cleaning component 30 to rotate when the water pressure is reduced, and ensuring the stability of the water pattern of the water outlet 300. When the water supply to the shower head stops, the first limit assembly is separated from the second limit assembly 53 to avoid interfering with the rotation of the impeller assembly 20 in the second direction, so that the energy storage component 40 can release potential energy, drive the impeller assembly 20 to rotate in the second direction, drive the cleaning component 30 to rotate to clean the water outlet tray, dry the residual water on the cleaning component 30 and destroy the water tension at the water outlet hole 300, so that the residual water in the shower head can be quickly discharged from the water outlet hole 300 under the drive of the cleaning component 30.

[0095] In the exemplary embodiment, please combine Figure 4 , Figure 8 , Fig. 9 , Fig.11 , Fig.12 and Figures 14 to 17The housing mechanism 10 is further provided with a flow hole 700. The flow hole 700 is connected between the water inlet hole 200 and the cavity 100.

[0096] The shower head further includes a valve core mechanism 50, which elastically abuts against the housing mechanism 10 to seal the flow hole 700. The valve core mechanism 50 is configured to be driven by water entering the water inlet hole 200 to open the flow hole 700 and generate a reset driving force. In this way, the water inlet hole 200 and the cavity 100 can be isolated after the water supply to the shower head is stopped by the configuration of the valve core mechanism 50, so as to prevent water from entering the cavity 100, thereby reducing the amount of residual water in the cavity 100, and facilitating the complete drainage of the residual water in the cavity 100 under the drive of the cleaning member 30.

[0097] The valve core mechanism 50 includes a valve core 51 and a first elastic member 52. The valve core 51 is coaxially arranged with the flow hole 700 and is slidably connected with the housing mechanism 10 to ensure the reliability of the valve core 51 sealing and opening the flow hole 700.

[0098] The first elastic member 52 is elastically clamped between the housing mechanism 10 and the valve core 51, driving the valve core 51 to seal the flow hole 700. The valve core 51 is configured to be driven by water entering the water inlet hole 200, opening the flow hole 700 and compressing the first elastic member 52 to generate a driving force for the valve core 51 to return to its original position.

[0099] The flow hole 700 is provided in the housing assembly 13. The valve core 51 includes a rod 511 and a plug 512. The housing assembly 13 has a guide hole 800, and the rod 511 is inserted into the guide hole 800 and slidably connected with the housing assembly 13 to ensure the stability of the movement path of the valve core 51 and avoid deviation under the drive of water.

[0100] The plug 512 is disposed at one end of the rod 511 and can abut against the housing assembly 13 to seal the flow hole 700. The end of the guide hole 800 close to the valve core 51 has a narrowing section, which gradually narrows from the end close to the valve core 51 to the end away from the valve core 51, so as to facilitate the positioning of the plug 512 and the flow hole 700 and ensure the reliability of the sealing of the flow hole 700. Fig. 9 and Fig.11 As shown, a conical surface 5121 may also be provided at one end of the plug 512 facing the flow hole 700 to further facilitate the positioning of the plug 512 and the flow hole 700 .

[0101] In addition, a sealing ring 5122 may be provided on the outer circumferential side of the plug 512 to improve the sealing performance of the flow hole 700. The sealing ring 5122 may be detachably connected to the plug 512, or may be integrally formed with the plug 512.

[0102] The first elastic member 52 may be a spring, and may be elastically clamped between the housing assembly 13 and the valve core 51. The housing assembly 13 and the valve core 51 are respectively provided with a first positioning groove 901 and a second positioning groove 902, which are arranged opposite to each other along the moving direction of the valve core 51. The first elastic member 52 is sleeved on the rod 511, and the two ends are respectively positioned at the first positioning groove 901 and the second positioning groove 902, so as to ensure the stability of the position of the first elastic member 52 and the stability of the elastic deformation.

[0103] like Fig. 9 , Fig.12 , Fig.15 and Fig.17 An annular limiting portion 5123 is also provided on the circumferential outer side of the plug 512 and is arranged around the plug 512 , which can prevent the valve core 51 from extending out of the flow hole 700 under the drive of the first elastic member 52 .

[0104] In the exemplary embodiment, please combine Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Figures 11 to 18 One of the first limit assembly and the second limit assembly 53 is arranged on the impeller assembly 20, and the other of the first limit assembly and the second limit assembly 53 is arranged on the valve core 51, and is arranged on the housing mechanism 10 through the valve core 51, and is arranged to be able to move with the valve core 51 when the valve core 51 is driven by water entering the water inlet hole 200, so that the first limit assembly contacts the second limit assembly 53.

[0105] The first limiting assembly includes a plurality of limiting protrusions 60, and the plurality of limiting protrusions 60 are arranged at intervals around the third direction, and the third direction is coaxially arranged with the rotation axis of the impeller assembly 20. Figure 8 , Fig.11 , Fig.14 and Fig.16 The arrow Z in the middle points to the direction.

[0106] When the valve core 51 is driven by water entering the water inlet hole 200, the second limit assembly 53 can be placed between adjacent limit protrusions 60 to limit the impeller assembly 20 from rotating in the second direction. In the disclosed embodiment, the first limit assembly is disposed on the impeller assembly 20. The second limit assembly 53 is disposed on the valve core 51. In this way, the plurality of limit protrusions 60 and the second limit assembly 53 can be arranged to prevent the impeller assembly 20 from rotating in the second direction after the water pressure is reduced (water supply to the showerhead is not stopped), thereby preventing the energy storage component 40 from releasing potential energy to drive the cleaning component 30 to rotate when the water pressure is reduced, thereby ensuring the stability of the water pattern of the water outlet 300. When the water supply to the shower head is stopped, the valve core 51 is reset under the drive of the first elastic member 52, thereby driving the second limit assembly 53 to reset, so as to avoid interference with the impeller assembly 20 rotating in the second direction, so that the energy storage member 40 can release potential energy, drive the impeller assembly 20 to rotate in the second direction, drive the cleaning member 30 to rotate to clean the water outlet tray, dry the residual water on the cleaning member 30 and destroy the water tension at the water outlet 300, so that the residual water in the shower head can be quickly discharged from the water outlet 300 under the drive of the cleaning member 30.

[0107] It can be understood that in other embodiments, at least one of the first limit assembly and the second limit assembly 53 can also be driven by a button. The button is movably mounted on the housing mechanism 10. Under manual drive, the button can move relative to the housing mechanism 10, thereby driving at least one of the first limit assembly and the second limit assembly 53, so that the non-return mechanism switches between the limit state and the separation state. For example, when supplying water to the shower, the first limit assembly can be driven by the button to contact the second limit assembly 53, and then after the water pressure is reduced (the water supply to the shower is not stopped), the impeller assembly 20 can be guided to rotate in the first direction all the time. When the water supply to the shower is stopped, the first limit assembly 53 can be driven by the button to separate from the second limit assembly to avoid interfering with the rotation of the impeller assembly 20 in the second direction.

[0108] In addition, in some embodiments, the number of the limiting protrusion 60 can also be one. When the valve core 51 is driven by water entering the water inlet hole 200 or by a button, one of the limiting protrusion 60 and the second limiting component 53 can be placed on the rotation path of the other, so that the limiting protrusion 60 contacts the second limiting component 53, thereby limiting the impeller assembly 20 from rotating in the second direction.

[0109] In the exemplary embodiment, please combine Figure 5 , Fig. 9 and Fig.12 The limiting protrusion 60 has a limiting surface 61 and a guide surface 62 which are sequentially arranged along the first direction.

[0110] The second limiting assembly 53 includes a limiting member 531 and a second elastic member 532. The limiting member 531 is movably mounted on the valve core 51 and can slide relative to the valve core 51. In this way, the accuracy of the moving direction of the limiting member 531 can be ensured under the restriction of the valve core 51.

[0111] The second elastic member 532 is elastically clamped between the valve core 51 and the limit member 531, and can drive the limit member 531 to move toward the impeller assembly 20, so that when the limit member 531 encounters an obstruction during the movement with the valve core 51, the second elastic member 532 will be compressed, and the limit member 531 can elastically abut against the obstruction (such as the limit protrusion 60).

[0112] The limit member 531 is configured to move with the valve core 51 when the valve core 51 is driven by water entering the water inlet hole 200, so as to be placed between adjacent limit protrusions 60. During the rotation of the impeller assembly 20 along the first direction, the limit member 531 can slide along the guide surface 62 and compress the second elastic member 532, thereby generating a driving force for resetting the limit member 531, so that the second elastic member 532 can adjust the position of the limit member 531 in real time during the rotation of the impeller assembly 20 along the first direction, so as to avoid the limit member 531 affecting the rotation of the impeller assembly 20.

[0113] When the impeller assembly 20 rotates in the second direction, the limiting member 531 can abut against the limiting surface 61 to limit the rotation of the impeller assembly 20 in the second direction. At this time, the position between the limiting member 531 and the limiting protrusion 60 is fixed, and the second elastic member 532 maintains the original compression degree, so that the limiting member 531 is stably located between adjacent limiting protrusions 60, ensuring the reliability of limiting the rotation of the impeller assembly 20.

[0114] In the exemplary embodiment, please combine Figure 5 , Figure 8 , Fig. 9 , Fig.11 and Fig.12 , the valve core mechanism 50 and the impeller assembly 20 are arranged relatively along the third direction. The limiting protrusion 60 is arranged on the side of the impeller assembly 20 facing the valve core mechanism 50 along the third direction, the valve core mechanism 50 can be driven by the water entering the water inlet hole 200 to move along the fourth direction, and the limiting member 531 can slide relative to the valve core 51 along the fourth direction, and the fourth direction is parallel to the third direction. Since the limiting member 531 needs to be placed between adjacent limiting protrusions 60, and multiple limiting protrusions 60 are arranged around the third direction, the moving path of the limiting member 531 is parallel to the axial direction of the impeller assembly 20 and is eccentrically arranged, so that the force of the limiting member 531 acting on the valve core 51 through the second elastic member 532 is roughly parallel to the direction of the force of the first elastic member 52 acting on the valve core 51, so that the force on the valve core mechanism 50 is relatively stable, thereby ensuring the reliability of the valve core mechanism 50 sealing the flow hole 700 and opening the flow hole 700.

[0115] It can be understood that in other embodiments, the valve core mechanism 50 and the impeller assembly 20 can also be arranged in sequence along a direction perpendicular to the third direction, the limiting protrusion 60 is arranged on the circumferential outer side of the impeller assembly 20, and the limiting member 531 can slide relative to the valve core 51 along a fourth direction, and the fourth direction is parallel to the plane where the first direction is located.

[0116] In the exemplary embodiment, please combine Figure 4 , Fig. 9 and Fig.12 The end of the stopper 531 facing the impeller assembly 20 has a spherical cap 5311. The dimension of the spherical cap 5311 along the fourth direction is smaller than the dimension of the stopper surface 61 along the fourth direction, so that the stopper 531 and the stopper surface 61 are more reliably abutted, and the stopper 531 can be prevented from sliding relative to the stopper 531 along the spherical cap 5311, so that the stopper 531 and the stopper surface 61 fail to cooperate.

[0117] The guide surface 62 has a first arc surface 621 and a second arc surface 622. The first arc surface 621 and the second arc surface 622 are connected in sequence and gradually approach the impeller assembly 20 along the first direction. In this way, when the impeller assembly 20 rotates in the first direction, the spherical crown 5311 can slide onto the limiting protrusion 60 through the second arc surface 622 and the first arc surface 621 in sequence. The first arc surface 621 and the second arc surface 622 cooperate with the spherical crown 5311, so that the limiting member 531 slides relatively to the limiting protrusion 60 more smoothly, avoiding interference with the rotation of the impeller assembly 20.

[0118] The first curved surface 621 protrudes toward the outside of the limiting protrusion 60, and the second curved surface 622 protrudes toward the inside of the limiting protrusion 60, so that when the spherical crown 5311 slides onto the limiting protrusion 60, the spherical crown 5311 can first contact with the second curved surface 622 which roughly matches the curvature of the spherical crown 5311, ensuring that the spherical crown 5311 and the second curved surface 622 have a larger contact surface area, thereby ensuring the stability of the limiting protrusion 60 driving the limiting member 531 in the initial stage of the sliding of the spherical crown 5311 relative to the limiting protrusion 60, and the second curved surface 622 has a certain wrapping property on the spherical crown 5311, so that the force direction of the limiting member 531 is roughly parallel to its preset moving direction. Afterwards, the spherical crown 5311 contacts the first arc surface 621. At this time, the spherical crown 5311 and the first arc surface 621 are in point contact, and the contact area is small, thereby reducing the friction resistance between the spherical crown 5311 and the limiting protrusion 60, so that the limiting member 531 can pass over the limiting protrusion 60 more smoothly and be placed between another adjacent limiting protrusion 60.

[0119] like Figure 5As shown, the limiting protrusion 60 is arranged on a side of the impeller assembly 20 facing the valve core mechanism 50 along the third direction, and the first arc surface 621 and the second arc surface 622 are connected in sequence and spirally descend along the first direction.

[0120] In the exemplary embodiment, please combine Figure 8 , Fig. 9 , Fig.11 and Fig.12 The limiting surface 61 extends along the fourth direction, so that the limiting surface 61 has a larger size on the rotation path of the limiting protrusion 60 to abut against the limiting member 531, thereby improving the reliability of the abutment with the limiting member 531.

[0121] In the present disclosure, Figure 4 , Fig. 9 and Fig.12 As shown, the valve core 51 is provided with a through space 1000, and the through space 1000 penetrates the valve core 51 along the fourth direction, and forms a guide through hole 1100 on the side of the valve core 51 facing the impeller assembly 20. The stopper 531 is rod-shaped. The stopper 531 matches the guide through hole 1100 and is slidably connected with the valve core 51 through the guide through hole 1100. An annular protrusion 533 is provided on the circumferential outer side of the stopper 531, and the annular protrusion 533 is accommodated in the through space 1000. The second elastic member 532 can drive the stopper 531 to move toward the impeller assembly 20, so that the annular protrusion 533 abuts against the valve core 51. The circumferential outer side of the annular protrusion 533 is fitted with the inner wall of the through space 1000 formed by the valve core 51, so that the annular protrusion 533 can be slidably connected with the valve core 51 through the through space 1000, further improving the stability of the stopper 531 sliding relative to the valve core 51. A sealing cover 54 is provided on the side of the through-space 1000 away from the impeller assembly 20 to seal the side. A third positioning groove 903 is provided on the side of the sealing cover 54 facing the through-space 1000, a positioning column 534 is provided on the side of the stopper 531 facing the through-space 1000, and the second elastic member 532 can be a spring, which is accommodated in the through-space 1000. The two ends of the second elastic member 532 are respectively positioned and connected with the third positioning groove 903 and the positioning column 534 to ensure the stability of the position of the second elastic member 532 and the stability of elastic deformation.

[0122] Please combine Figure 2 , Figure 4 , Figure 8 and Fig.11The housing assembly 13 further includes a second housing 133, a third housing 134 and a second cover 135. The impeller assembly 20 is rotationally connected to the second housing 133, and is connected to the energy storage member 40 through the second housing 133 and the first housing 131 in turn, and is connected to the cleaning member 30 through the first cover 132. The second cover 135 is disposed in the second housing 133, and the flow hole 700 is located in the second cover 135. The third housing 134 is accommodated in the space enclosed by the second housing 133 and the second cover 135, and the valve core 51 is penetrated in the third housing 134 and is slidably connected to the second housing 133. The first elastic member 52 is elastically clamped between the third housing 134 and the valve core 51. The first positioning groove 901 is located in the third housing 134.

[0123] In the exemplary embodiment, please combine Figures 13 to 18 The limiting protrusion 60 is a ratchet. The second limiting component 53 includes a plug-in end 535. The ratchet is inclined toward one side of the second direction.

[0124] The plug end 535 is configured to move with the valve core 51 when the valve core 51 is driven by water entering the water inlet hole 200, so as to be placed between adjacent limiting protrusions 60. When the impeller assembly 20 rotates in the first direction, the plug end 535 can be driven by multiple limiting protrusions 60 to move out from between adjacent limiting protrusions 60, and move into between adjacent limiting protrusions 60 under the elastic force of the plug end 535 itself or the external force. When the impeller assembly 20 rotates in the second direction, the plug end 535 can be engaged with the limiting protrusion 60 to limit the impeller assembly 20 from rotating in the second direction. In this way, a ratchet pawl structure can be formed between the second limiting assembly 53 and the impeller assembly 20, and after water is supplied to the shower head, it is ensured that the impeller assembly 20 can rotate in the first direction and limit the impeller assembly 20 from rotating in the second direction.

[0125] The plug end 535 can be driven by the plurality of limiting protrusions 60 to undergo elastic deformation, and reset under its own elastic force to move between adjacent limiting protrusions 60. Alternatively, the plug end 535 can be driven by the plurality of limiting protrusions 60 to deviate from the rotation path of the limiting protrusions 60, and reset and move back between adjacent limiting protrusions 60 under the action of an external force (for example, a driving force generated by a torsion spring disposed between the plug end 535 and the valve core 51).

[0126] In the disclosed embodiment, the second limit assembly 53 further includes a connecting member 536, which is disposed on the valve core 51, and the plug end 535 has elastic deformation performance and is disposed on the connecting member 536. The connecting member 536 can increase the connection surface area between the plug end 535 and the valve core 51, and improve the connection stability between the valve core 51 and the plug end 535. In the disclosed embodiment, the connecting member 536 is sleeved on the valve core 51.

[0127] The housing mechanism 10 is provided with a guide groove 1200, the extension direction of the guide groove 1200 is parallel to the moving direction of the plug end 535, and the plug end 535 is inserted into the guide groove 1200 and is slidably connected with the housing mechanism 10. In this way, by providing the guide groove 1200, the connection area between the plug end 535 and the housing mechanism 10 can be increased, and the stability of the movement of the plug end 535 can be improved. In addition, by providing the guide groove 1200, the housing mechanism 10 can provide support for the plug end 535, and the reliability of the plug end 535 and the limiting protrusion 60 can be improved.

[0128] like Figures 13 to 17 As shown, the housing assembly 13 further includes a second housing 133, a fourth housing 136 and a third cover 137. The impeller assembly 20 is rotatably connected to the second housing 133, and is connected to the energy storage member 40 through the second housing 133 and the first housing 131 in sequence, and is connected to the cleaning member 30 through the first cover 132. The fourth housing 136 is disposed on the second housing 133. The third cover 137 is disposed on the fourth housing 136. The flow hole 700 is located on the third cover 137. The guide groove 1200 is located on the fourth housing 136. The valve core 51 is accommodated in the space surrounded by the fourth housing 136 and the third cover 137, and is penetrated through the fourth housing 136 and slidably connected with the fourth housing 136. The first elastic member 52 elastically abuts between the fourth housing 136 and the valve core 51. The first positioning groove 901 is located on the fourth housing 136.
