The outer surface of the arc piece 41 is matched with the inner surface of the side wall 111 of the shower head 10, and the arc of the arc piece 41 is matched with the arc of the side wall 111 of the shower head 10.

[0052] Referring to Figure 2 , Figure 7 and Figure 9 , in the embodiment, the shower head 10 is provided with a water distribution cavity 123, and the water distribution cavity 123 has an inlet 1231 and the same number of outlets as the water outlet channels 131, that is, the outlets include two, which are a first outlet 1232 and a second outlet 1233. The first outlet 1232 is connected with the corresponding first water outlet channel 1311, and the second outlet 1233 is connected with the corresponding second water outlet channel 1312. The switching piece 30 moves in the water distribution cavity 123 to close or open the outlet, and the end of the pull rod 60 away from the push rod 50 extends into the water distribution cavity 123 and is connected with the switching piece 30.

[0053] In order to further realize labor-saving driving, in the embodiment, the switching piece 30 has a top surface 31 and a bottom surface 32, one of the top surface 31 and the bottom surface 32 of the switching piece 30 is sealingly matched with the inner wall of one side of the water distribution cavity 123 having an outlet, and the other of the top surface 31 and the bottom surface 32 of the switching piece 30 is sealingly matched with the inner wall of the other side of the water distribution cavity 123 opposite to the outlet. Specifically, the two outlets of the water distribution cavity 123 are arranged on the bottom wall of the water distribution cavity 123, the bottom surface 32 of the switching piece 30 is sealingly matched with the bottom wall of the water distribution cavity 123, and the top surface 31 of the switching piece 30 is sealingly matched with the top wall of the water distribution cavity 123. A water passing groove 33 in communication with the inlet 1231 is arranged between the top surface 31 and the bottom surface 32 of the switching piece 30. The water in the water passing groove 33 can simultaneously exert water pressure on the top surface 31 and the bottom surface 32 on both sides thereof, so that the water pressure acting on the switching piece 60 can be fully or partially offset, water pressure balance or water pressure reduction is realized, further driving is more labor-saving, and the switching feeling is better. More preferably, the water pressure of the water in the water passing groove 33 on the top surface 31 and the bottom surface 32 of the switching piece 30 is the same, so that complete water pressure balance can be realized. The top surface 31 and the bottom surface 32 of the switching piece 30 are respectively provided with annular grooves, and sealing rings are respectively arranged in the annular grooves. Specifically, the first sealing ring 311 is arranged in the annular groove of the top surface 31, and the second sealing ring 321 is arranged in the annular groove of the bottom surface 32.

[0054] The working process of the embodiment is as follows:

[0055] As shown in Figures 10 to 12 , at this time, the push button 40 is located at the first water outlet position, the push rod 50 is close to the water distribution cavity 123, the sliding block 51 is at the first position on the push rod 50, the one end of the pull rod 60 away from the push rod 50 extends into the water distribution cavity 123 to a greater depth, the switching piece 30 opens the first outlet 1232 and closes the second outlet 1233, the first water outlet channel 1311 discharges water, and the handheld shower is in the first water outlet mode;

[0056] When it is needed to switch to the second water outlet channel 1312 to discharge water, in the state shown in Figure 10 , the push button 40 is pushed to the second water outlet position along the clockwise direction, at this time, as shown in Figures 13 to 15 , the push rod 50 slides along an arc line away from the water distribution cavity 123 along with the push button 40, the sliding block 51 on the push rod 50 slides along a straight line guide rail 121 away from the water distribution cavity 123 along a straight line, and simultaneously, the sliding block 51 slides from the first position (as shown in Figure 5 , Figure 10 to the second position (as shown in Figure 6 , Figure 13As shown, the push rod 50 drives the pull rod 60 to slide in a straight line away from the water distribution chamber 123 via the slider 51. The pull rod 60 then drives the switching component 30 to move to the position of closing the first outlet 1232 and opening the second outlet 1233, thereby realizing the water circuit switching. Water flows out of the second water outlet channel 1312, and the hand shower is in the second water outlet mode.

[0057] exist Figure 13 In this state, when it is necessary to switch to the first water outlet channel 1311, push the push button 40 counterclockwise to the first water outlet position. At this time, return to Figures 10 to 12 In this state, the push rod 50 slides in an arc towards the water distribution chamber 123 along the push button 40, and the slider 51 on the push rod 50 slides in a straight line relative to the shower head 10 along the linear guide rail 121 towards the water distribution chamber 123. At the same time, the slider 51 moves relative to the push rod 50 from the second position (e.g., Figure 6 , Figure 13 (As shown) Slide to the first position (as shown) Figure 5 , Figure 10 As shown, the push rod 50 drives the pull rod 60 to slide linearly towards the water distribution chamber 123 via the slider 51. The pull rod 60 then drives the switching component 30 to move to the position of opening the first outlet 1232 and closing the second outlet 1233, thereby realizing the water circuit switching. Water flows out of the first water outlet channel 1311, and the hand shower returns to the first water outlet mode. This achieves repeated switching.

[0058] Compared with the existing handheld shower head that uses a knob to drive the water outlet cover to rotate, this invention has fewer rotating parts and a simpler structure. Since there is no need to drive the cover assembly, it can be operated with less effort. Furthermore, the operation method of driving the push knob to slide along the side wall of the shower head in an arc is novel and unique.
