The inner side wall of the sealing shaft 13 is away from the water passing port 155 to allow water to pass through. Refer to Figure 6 The shown shower head is in a water passing state. Water flows in from the water inlet 154, passes through the water passing port 155, flows to the outer side surface of the sealing shaft 13, then flows to the second cavity and the water passing cavity, and then flows to the water outlet assembly, and flows out from the water outlet for the user to use; at the same time, water flows into the third cavity from the outside of the sealing shaft 13 through the water passing holes 134 to ensure the balance of the internal and external water pressures at the end surface of the third cavity.

[0061] Continue to press the button 31, and the button 31 pushes the rotating part to push the push rod 36, which is equivalent to continuously pressing the push rod 36; continue to press the push rod 36, the rotating shaft 37 rotates, and under the action of the third spring 35, the third inclined surface leaves the first inclined surface 382 and continues to rotate along the second inclined surface 383, and the rotating bump 371 enters the guide groove 384 to make the sealing shaft 13 in the second position, and the inner side of the sealing shaft 13 overlaps with the water passing port 155 to stop water, refer to Figure 7 The shower head is in a water-stop state, the water passing port 155 overlaps with the inner side wall of the sealing shaft 13, the first sealing ring 156 enters the third cavity, and the water flow enters from the water inlet 154, flows through the water passing port 155 to the outer side surface of the sealing shaft 13, and is restricted by the first sealing ring 156 and cannot flow to the second cavity. At the same time, the internal and external water pressures on the side wall of the sealing shaft 13 between the two first sealing rings 156 are balanced. At the same time, the inner diameter of the annular cavity is the same as the outer diameter of the fourth column platform 132, so that the pressure-bearing areas on the inner and outer sides of the end surface of the third cavity are the same to ensure the air pressure balance on the end surface of the third cavity, so as to ensure that the switching component 3 and the fourth spring 14 can push the sealing shaft 13 to move up and down.

[0062] In the present invention, by arranging the water passing component 1 and the switching component 3 on the body 4, and setting the water pressure balance in the water passing component 1, the switching component 3 can switch the water passing component 1 to conduct water or stop water; the pressure-bearing areas of the water passing component 1 are set to be equal to ensure the water pressure balance on the inner and outer end surfaces of the water passing component 1; a link mechanism is formed by the push rod 36, the rotating shaft 37, the anti-rotation cylinder 38 and the third spring 35, and then the force of operating the button 31 outside the body 4 is transmitted to the link mechanism through the swing rod 32 and the crankshaft 34 to push the sealing shaft 13 and the plug 15 to form relative movement to conduct water or stop water.
