[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] like Figures 1 to 10 As shown: A water outlet switching mechanism of a shower head of the present invention comprises:

[0041] The main body 10 has a accommodating cavity 11, including a shower head and a shower rod. The accommodating cavity 11 in this embodiment refers to the inner cavity space of the shower head. In this embodiment, the main body 10 includes a water outlet panel 12 connected to the water outlet hole 22. Specifically, the water outlet panel 12 is arranged on the front of the shower head.

[0042] The valve body 20 is disposed in the accommodating cavity 11 and is provided with a water inlet channel 21 and a plurality of water outlet holes 22;

[0043] A valve core 30 is movably disposed within the valve body 20 and is provided with a sealing portion 31 for controlling the opening and closing of the water outlet 22. A plurality of valve cores 30 are provided, each corresponding to one of the water outlets 22. The plurality of valve cores 30 are arranged in parallel along a first plane on which the shower head is located. The valve cores 30 move in a direction parallel to the first plane.

[0044] The driving unit has a driving member 40 rotatably arranged in the accommodating cavity 11, and the rotation axis 40a line of the driving member 40 is arranged parallel to the first plane. The driving member 40 is provided with a plurality of driving parts 41 in parallel along the rotation axis 40a line, and the driving parts 41 are staggered along the circumferential direction of the driving member 40, wherein the driving parts 41 correspond one-to-one to the valve core 30 and cooperate with the valve core 30 in transmission.

[0045] In this embodiment, three water outlet holes 22 and three valve cores 30 are provided.

[0046] In this embodiment, a first elastic member 50 is further included. The first elastic member 50 provides a reset force on the valve core 30 to move in the direction of closing the water outlet 22, so that the valve core 30 can automatically reset. Specifically, the first elastic member 50 is pressed between the valve body 20 and the valve core 30, and the first elastic member 50 adopts a reset spring.

[0047] In this embodiment, a secondary water channel 23 connected to the water inlet channel 21 is further included.

The slider 60 is slidably arranged in a direction parallel to the first plane, and one end of the slider 60 is transmission-coordinated with the valve core 30, and the other end of the slider 60 is transmission-coordinated with the driving member 40. Specifically, the slider 60 is provided with a clamping portion 61, and the side of the connecting rod 34 close to the slider 60 is provided with a limiting groove 341 that is clamped and cooperated with the clamping portion 61.

[0050] In this embodiment, an anti-rotation rib 62 is provided on a side of the slider 60 close to the driving member 40 , and the anti-rotation rib 62 can prevent the driving member 40 from rotating in the reverse direction.

[0051] In this embodiment, the driving member 40 includes a rotating shaft 40a and a rotating drum 40b. The rotating drum 40b is sleeved on the outside of the rotating shaft 40a and is limitedly matched with the rotating shaft 40a along the circumferential direction of the rotating drum 40b. The driving part 41 is a protrusion 41 arranged on the outer periphery of the rotating drum 40b. Specifically, the outer wall of the rotating shaft 40a is axially provided with a limiting rib 42, and the inner wall of the rotating drum 40b is correspondingly axially provided with a limiting groove 43.

[0052] In this embodiment, the driving unit further includes a button 70 and a transmission member 80 that cooperate with each other in transmission, and the transmission member 80 cooperates with the driving member 40 in transmission, so that the button 70 drives the driving member 40 to move through the transmission member 80. Specifically, the button 70 is slidably arranged on the back of the shower head, and further includes a second elastic member 90 that provides elastic reset force to the button 70, and the second elastic member 90 is a compression spring.

[0053] In this embodiment, the transmission member 80 is provided with an abutment portion 81 that cooperates with the button 70 for transmission, and the transmission member 80 is also provided with a ratchet 82. The driving member 40 is provided with a ratchet 44 that intermittently cooperates with the ratchet 82 for transmission, and then the driving member 40 can rotate a preset angle through the cooperation between the ratchet 82 and the ratchet 44. Specifically, the ratchet 44 is arranged in the middle of the rotating shaft 40a.

[0054] In this embodiment, the transmission member 80 includes an elastic arm 83, one end of which is provided with a fixing portion 84, and the fixing portion 84 is fixed to the accommodating cavity 11 by a fastener. The ratchet 82 and the abutment portion 81 are both provided on the other end of the elastic arm 83.

[0055] In this embodiment, the valve body 20 includes an annular pipe 24, the water inlet channel 21 is formed in the annular pipe 24, the water outlet hole 22 is arranged on the front side of the annular pipe 24, and the driving member 40 and the slider 60 are both movably arranged in the space enclosed by the annular pipe 24, with a compact structure and space saving.

[0056] The specific working process of this embodiment is as follows:

[0057] When the button 70 is pressed, the button 70 presses against the contact portion 81 of the transmission member 80, causing the elastic arm 83 of the transmission member 80 to deform. At the same time, the ratchet 82 cooperates with the ratchet wheel 44 to push the rotating shaft 40a to rotate a preset angle. The rotating drum 40b rotates synchronously with the rotating shaft 40a. One of the protrusions 41 of the rotating drum 40b pushes the corresponding slider 60 to slide. The slider 60 drives the corresponding valve core 30 to move, causing the sealing portion 31 of the valve core 30 to move away from the corresponding water outlet 22, thereby opening the water outlet 22 to discharge water. When the button 70 is released, the elastic arm 83 returns to its original position, causing the ratchet 82 to abut against the ratchet wheel 44, thereby completing the switching action.

[0058] When the button 70 is pressed again, the ratchet 82 of the transmission member 80 pushes the rotating shaft 40a to rotate again by a preset angle, and the rotating drum 40b rotates synchronously with the rotating shaft 40a. The other protrusion 41 of the rotating drum 40b pushes the corresponding slider 60 to slide, and the slider 60 drives the corresponding valve core 30 to move, so that the sealing part 31 of the valve core 30 is away from the corresponding water outlet 22, thereby opening the other water outlet 22 to discharge water.

[0059] In this solution, a plurality of valve cores 30 are arranged in parallel along the first plane where the shower head is located. The valve cores 30 move in a direction parallel to the first plane, thereby making the shower head structure more compact, saving space in the thickness of the shower head, and making the shower head thinner. In addition, by providing a rotating driving member 40, the movement stroke of the valve core 30 can be increased within a limited space, thereby improving the water flow rate of the shower head, and the operation is convenient and labor-saving.
