One end of the push rod 300 is slidably disposed in the valve body 200, and the other end of the push rod 300 may be disposed through the third through hole 262 to be exposed out of the valve body 200. The air chamber 330 is defined between the push rod 300 and the inside of the valve body 200, and the push rod 300 is provided with a first water diversion groove 310 and a second water diversion groove 320 at intervals along the axial direction thereof, the inside of the push rod 300 is also defined with an air passage 301, and two ends of the air passage 301 are respectively communicated with the air chamber 330 and the external space of the push rod 300.

Wherein the push rod 300 has a first position and a second position, and the push rod 300 can be moved from the first position to the second position by manually pushing the push rod 300. When the first water inlet 121 is filled with water and the push rod 300 is at the first position, for example, the push rod 300 is at the position shown in fig. 3, the water entering from the first water inlet 121 can sequentially pass through the second water inlet 220, the first water diversion trench 310 and the first water passing opening 230, and finally be discharged from the first water outlet 131, and the top shower head is discharged.

When the user desires to hold the shower to discharge water, the push rod 300 is pressed, causing the push rod 300 to switch to a second position, such as the position shown in fig. 4. During the pressing process, the air chamber 330 is pressed by the push rod 300, the volume is reduced, and air in the air chamber 330 is discharged to the outside through the air passage 301, for example, as shown by an arrow in fig. 5.
