[0022] As shown in FIGS. 1 to 4, some embodiments of this application provide a shower head that can improve the diversity of the water spraying method and improve the stability and efficiency of the adjustment of the water spraying method.

[0023] The shower head includes a housing 100, a water inlet joint 200, a water spraying assembly 300, a switching assembly 400, and an actuating member 500.

[0024] The housing 100 includes a handle portion 110 and a mounting portion 120 that are connected. Also, the connection method between the handle portion 110 and the mounting portion 120 may be any one of screw connection, connection by bolts, engagement, adhesion, connection by magnetic attraction, or integral molding, and it can be specifically set according to the actual situation.

[0025] In this embodiment, by integrally molding the handle portion 110 and the mounting portion 120 to form the housing 100, the stability, overall strength, and durability of the housing 100 can be improved.

[0026] Also, the water inlet joint 200 is installed inside the handle portion 110. One end of the water inlet joint 200 is connected to an external water source, and the other end of the water inlet joint 200 is connected to the water discharge assembly 300. Thus, water from the outside enters the water discharge assembly 300 through the water inlet joint 200 and is discharged by the water discharge assembly 300.

[0027] The water discharge assembly 300 is attached to the mounting portion 120 and includes a water discharge assembly body 310, a back cover 320, and a water distribution plate 330. The water distribution plate 330 is installed between the water discharge assembly body 310 and the back cover 320. The water discharge assembly body 310 has a plurality of independent water outlet passages, that is, the water discharge assembly body 310 can realize a plurality of different water discharge modes. The water distribution plate 330 is rotatably installed on the water discharge assembly body 310. Thus, in the process of the water distribution plate 330 rotating relative to the water discharge assembly body 310, the water distribution plate 330 can adjust the water discharge mode of the water discharge assembly body 310.

[0028] The switching assembly 400 is installed inside the housing 100 and includes a driving member 410, an elastic member 420, and a ratchet gear 430.

[0029] The ratchet gear 430 is connected to the water distribution plate 330. In this embodiment, the ratchet gear 430 is fixedly connected to the water distribution plate 330, so that the water distribution plate 330 is synchronously rotationally driven during the rotation process of the ratchet gear 430.

[0030] Also, the drive member 410 is rotatably connected to the back cover 320, that is, the drive member 410 is rotatable relative to the back cover 320. Thus, during the process of the drive member 410 rotating relative to the back cover 320, the ratchet gear 430 is driven, and the water distribution plate 330 is rotationally driven by the ratchet gear 430.

[0031] The drive member 410 is installed on the side of the back cover 320 away from the water discharge assembly body 310 and has a first ratchet claw 440 that meshes with the ratchet gear 430. Specifically, the first ratchet claw 440 is installed on the side of the drive member 410 facing the ratchet gear 430 and is configured to mesh with the ratchet gear 430.

[0032] One end of the elastic member 420 is connected to the drive member 410, and the other end is connected to the water discharge assembly body 310. The elastic member 420 is configured to pull and return the drive member 410. Specifically, when the drive member 410 rotationally drives the ratchet gear 430 by a predetermined angle under the action of the pulling force of the execution member 500, the elastic member 420 is in a tensioned state, and the potential energy due to the elastic force is stored in the elastic member 420. When the external force acting on the execution member 500 is removed, the elastic member 420 tries to return to its natural length under the action of the potential energy due to the elastic force, that is, the elastic member 420 applies a pulling force to the drive member 410, whereby the drive member 410 returns under the action of the pulling force of the elastic member 420.

[0033] The return here means that the drive member 410 returns to the initial position under the action of the elastic force of the elastic member 420. When the drive member 410 is located at the initial position, the first ratchet claw 440 on the drive member 410 meshes with the ratchet gear 430.

[0034] The actuating member 500 includes a link 510, a slide block 520, and a switch 530.

[0035] The switch 530 is connected to the slide block 520, and the slide block 520 and the water inlet joint 200 are slidably connected along the longitudinal direction of the water inlet joint 200. The slide block 520 can slide along the longitudinal direction of the water inlet joint 200 with respect to the water inlet joint 200.

[0036] Also, one end of the link 510 is connected to the slide block 520, that is, the link 510 moves synchronously with the slide block 520, and the other end of the link 510 is hinged to the driving member 410, that is, the link 510 is rotatably connected to the driving member 410, and the link 510 is configured to rotationally drive the driving member 410. The link 510 rotationally drives the driving member 410 in the process of moving along the longitudinal direction of the water inlet joint 200.

[0037] In this embodiment, the switch 530 drives the slide block 520 to slide in the positive direction along the longitudinal direction of the water inlet joint 200 under the action of an external force, and the slide block 520 drives the link 510 to move in the positive direction. When the link 510 moves in the positive direction, the link 510 rotationally drives the driving member 410 by a predetermined angle, and the first ratchet pawl 440 rotationally drives the ratchet gear 430 by a predetermined angle. Since the ratchet gear 430 and the water distribution plate 330 are connected, the ratchet gear 430 drives the water distribution plate 330 to rotate synchronously by a predetermined angle. And in the process of the driving member 410 rotating, the elastic member 420 is stretched. At this time, the potential energy of position due to the elastic force is stored in the elastic member 420, that is, the elastic member 420 tries to return to its natural length under the action of the potential energy of position due to the elastic force. That is, at this time, the elastic member 420 applies a tensile force to the driving member 410.

[0038] In this embodiment, the predetermined angle is a positive integer multiple of the central angle corresponding to one tooth in the ratchet gear 430, that is, the predetermined angle can be the sum of the central angles corresponding to two or more teeth in the ratchet gear 430.

[0039] Moreover, moving in the positive direction means that the switch 530 moves in a direction away from the water discharge assembly main body 310 along the longitudinal direction of the water inlet joint 200.

[0040] After removing the external force acting on the switch 530, the elastic member 420 tries to return from the state of applying a tensile force to the driving member 410 in the tensile state to its natural length. Therefore, due to the action of elasticity, the elastic member 420 pulls the driving member 410 to rotate in the return direction, and the link 510 is driven to move in the reverse direction by the rotation of the driving member 410.

[0041] Moving in the reverse direction here means that the link 510 moves in a direction approaching the water discharge assembly main body 310 along the longitudinal direction of the water inlet joint 200.

[0042] Then, in the process of the driving member 410 rotating in the return direction, the second ratchet pawl 340 installed on the back cover 320 abuts against the ratchet gear 430. As a result, the second ratchet pawl 340 restricts the positions of the ratchet gear 430 and the water distribution plate 330, and can prevent the ratchet gear 430 from rotating along with the driving member 410. Thereby, the stability of the ratchet gear 430 and the water distribution plate 330 can be guaranteed, that is, the ratchet gear 430 and the water distribution plate 330 can maintain their current states.

[0043] Specifically, when the link 510 moves in the reverse direction, the slide block 520 and the switch 530 are driven to move in the reverse direction synchronously. When the drive member 410 returns, the slide block 520 and the switch 530 return synchronously, thereby realizing the switching of the water discharge mode. At this time, the water diversion hole 331 in the water diversion plate 330 communicates with one of the water outlet passages in the water discharge assembly main body 310, and the other water outlet passages in the water discharge assembly main body 310 are closed. When the drive member 410 rotates in the forward direction by a predetermined angle, the water inlet joint 200 communicates with one of the water outlet passages alternatively.

[0044] In this embodiment, one end of the water diversion plate 330 penetrates through the back cover 320 and the drive member 410 (a rotating shaft is installed on one side in the thickness direction of the water diversion plate 330, and the rotating shaft penetrates through the back cover 320 and the drive member 410, and the axis of the rotating shaft coincides with the axis of the water diversion plate 330), and the water diversion plate 330 is connected to the ratchet gear 430. In this embodiment, one end of the water diversion plate 330 (here, it refers to one end of the rotating shaft) engages with the ratchet gear 430 (for example, engages with the central hole of the ratchet gear 430), that is, the water diversion plate 330 and the ratchet gear 430 are fixedly connected, and the water diversion plate 330 and the ratchet gear 430 can rotate synchronously, and the drive member 410 drives the ratchet gear 430 and the water diversion plate 330 to rotate synchronously.

[0045] As shown in FIGS. 2 and 5, in some embodiments of the present application, the end of the back cover 320 facing the handle portion 110 communicates with one end of the water inlet joint 200, and the other end of the water inlet joint 200 communicates with an external water source.

[0046] Also, the end of the back cover 320 facing the water discharge assembly main body 310 communicates with the water discharge assembly main body 310 through the water diversion plate 330. Thereby, when the water in the water inlet joint 200 enters the back cover 320, the water diversion plate 330 adjusts the water discharge mode of the water discharge assembly main body 310, that is, switches the water discharge mode of the shower head.

[0047] Specifically, the second ratchet pawl 340 is installed on the side of the back cover 320 facing the ratchet gear 430, and is configured to mesh with the ratchet gear 430. The second ratchet pawl 340 restricts the reverse rotation of the ratchet gear 430, thereby ensuring the stability of switching between the water discharge modes.

[0048] As shown in FIGS. 2, 3 and 6, in some embodiments of the present application, a connecting portion 600 is provided at an end of the link 510 close to the second ratchet pawl, and the connecting portion 600 is movably connected to the driving member 410.

[0049] Specifically, the rotation axis of the driving member 410 and the rotation axis of the ratchet gear 430 are on the same line. Thereby, in the process of the driving member 410 rotating in the forward direction, the ratchet gear 430 can be coaxially rotationally driven.

[0050] A first guide hole 411 is provided in the driving member 410. The first guide hole 411 extends along the longitudinal direction of the driving member 410, and the longitudinal direction of the driving member 410 is perpendicular to the rotation axis.

[0051] Also, a connecting portion 600 is provided at an end of the link 510 close to the second ratchet pawl. The connecting portion 600 is movably installed in the first guide hole 411. That is, the end of the connecting portion 600 close to the driving member 410 is inserted into the first guide hole 411, and the connecting portion 600 is slidably connected to the first guide hole 411. Thereby, in the process of the link 510 moving in the forward direction or the reverse direction, the connecting portion 600 can drive the driving member 410 to move in the forward direction or the reverse direction.

[0052] As shown in FIG. 1, in some embodiments of the present application, a long hole 111 is provided on one side of the handle portion 110, and the long hole 111 is provided along the longitudinal direction of the housing 100.

[0053] A part of the switch 530 protrudes from the long hole 111, that is, a part of the switch 530 is located outside the handle part 110, and the user can touch the switch 530 to operate the switch 530.

[0054] In addition, the switch 530 is slidably connected to the long hole 111. A part of the switch 530 is located outside the handle part 110, and another part of the switch 530 is located inside the handle part 110 and is connected to the slide block 520. When the user pulls the switch 530, the switch 530 moves in a direction away from the mounting part 120 along the long hole 111, and the movable distance of the switch 530 is limited by the hole wall of the long hole 111. Thereby, the accuracy of the control of the moving position of the switch 530 is improved during the process that the user pulls the switch 530, the efficiency of switching the water spraying mode of the shower head is improved, and thus the user experience is improved.

[0055] As shown in FIGS. 2 and 4, in some embodiments of the present application, the link 510 includes a first connecting rod 511 and a first guide rod 512.

[0056] The connecting portion 600 is provided at an end of the first guide rod 512 close to the driving member 410. The axis of the connecting portion 600 is parallel to the axis of the ratchet gear 430. A second cylinder 513 is provided at an end of the first guide rod 512 away from the driving member 410. The axis of the connecting portion 600 is parallel to the axis of the second cylinder 513.

[0057] In addition, one end of the first connecting rod 511 is connected to the slide block 520, and the other end is connected to the second cylinder 513. The second cylinder 513 connects the first connecting rod 511 and the first guide rod 512. Thereby, the first connecting rod 511 and the first guide rod 512 can move synchronously.

[0058] Furthermore, along the longitudinal direction of the first guide rod 512, a position limiting hole 512a is provided in the first guide rod 512, that is, the position limiting hole 512a is provided along the longitudinal direction of the first guide rod 512.

[0059] In this embodiment, a position limiting member 700 is installed on the side of the water discharge assembly body 310 facing the drive member 410. A protruding base 710 is installed on the position limiting member 700. The protruding base 710 is inserted into the position limiting hole 512a. The protruding base 710 plays a role in position limiting and guiding with respect to the first guide rod 512. Thereby, the stability and smoothness of the first guide rod 512 during movement can be improved, and the stability of the first connecting rod 511 during movement can also be improved.

[0060] As shown in FIGS. 2 and 3, in some embodiments of the present application, the drive member 410 is rotatably installed between the back cover 320 and the ratchet gear 430, that is, the drive member 410 is rotatable with respect to the back cover 320 and the ratchet gear 430. In this way, during the return process of the drive member 410, it is possible to prevent the back cover 320 and the ratchet gear 430 from interfering with the drive member 410, and the smoothness and stability of the return of the drive member 410 can be guaranteed.

[0061] As shown in FIGS. 2, 5, and 7, in some embodiments of the present application, a protruding portion 321 is provided on the side of the back cover 320 facing the drive member 410. A through hole 412 is provided in the drive member 410. The drive member 410 is rotatably sleeved on the protruding portion 321 through the through hole 412. That is, the drive member 410 is rotatable around the axis of the protruding portion 321, and the axis of the through hole 412 coincides with the axis of the protruding portion 321.

[0062] In addition, a protruding block 322 is provided on the peripheral wall of the protruding portion 321, a guide groove 413 is provided on the inner wall of the driving member 410, the guide groove 413 communicates with the through hole 412, and the guide groove 413 is provided on the hole wall of the through hole 412. The protruding block 322 is fitted into the guide groove 413 and is configured to limit the rotation angle of the driving member 410.

[0063] The protruding portion 321 is in an annular shape, and the rotation axis of the water distribution plate 330 passes through the central hole of the protruding portion 321 and engages with the ratchet gear 430. The driving member 410 is annularly mounted on the outer periphery of the protruding portion 321 and is rotatably connected to the protruding portion 321.

[0064] By providing the protruding block 322 and the guide groove 413 corresponding to the protruding block 322, the rotation angle of the driving member 410 can be effectively limited, and the driving member 410 can be kept in a stable state under the action of the elastic force of the elastic member 420 and the pushing force of the pushing rod, thereby improving the operating stability of the driving member 410.

[0065] As shown in FIG. 4, in some embodiments of the present application, a second guide hole 521 is provided on the side of the slide block 520 facing the water inlet joint 200, and the second guide hole 521 extends along the longitudinal direction of the slide block 520.

[0066] In addition, a slide rail 210 is provided on the side of the water inlet joint 200 facing the slide block 520, and the slide rail 210 extends along the longitudinal direction of the water inlet joint 200.

[0067] The longitudinal direction of the water inlet joint 200 is parallel to the longitudinal direction of the slide block 520. As shown in FIG. 9, in this embodiment, the slide rail 210 is movably installed in the second guide hole 521, and the slide block 520 is slidably connected to the water inlet joint 200 by the second guide hole 521. The slide rail 210 and the second guide hole 521 play a role of position limitation and guide with respect to the slide block 520, thereby ensuring the stability and smoothness when the slide block 520 slides on the slide rail 210.

[0068] As shown in FIGS. 2, 7, and 8, in some embodiments of the present invention, a position limiting post 332 is provided on the side of the water distribution plate 330 facing the ratchet gear 430. The axis of the position limiting post 332 coincides with the axis of the water distribution plate 330, and the position limiting post 332 is perpendicular to the water distribution plate 330.

[0069] By inserting the end of the position limiting post 332 separated from the water distribution plate 330 into the through hole 412, the ratchet gear 430 and the water distribution plate 330 are coaxially connected, thereby realizing the coaxial rotation of the water distribution plate 330 and the ratchet gear 430.

[0070] It should be clearly stated here that in all the examples described and explained, the specific values are only exemplary and not limiting. Therefore, in other examples of the exemplary embodiments, other values may be selected.
