And the lower end of the switching bolt is matched and sealed in the inner pipe, and a third sealing position 30 is formed between the switching bolt and the inner pipe, so that the second cavity and the first cavity cannot be communicated at the upper end.

When the water-saving shower head is used, the switching between the upper water outlet and the lower water outlet can be realized by rotating the switching valve, and when water is suspended, the water-saving shower head can be automatically suspended, so that the condition of mistaken shower is avoided. When the switching valve is rotated to a lower water outlet gear, the first cavity is communicated with the lower water outlet end, the second cavity is sealed, and no water pressure exists in the second cavity; at the moment, when the lower water outlet end is closed, the switching bolt is kept still and cannot move upwards due to the fact that the sectional area of the second sealing position is larger than that of the first sealing position, and the upper water outlet end is effectively prevented from suddenly coming out of the hand. When the switching valve is rotated to an upper water outlet gear, the lower end of the first cavity is communicated with the second cavity, the pressure of the second sealing position is balanced with that of the third sealing position, water flow entering from the water inlet end acts on the first sealing position, the switching bolt is moved upwards, and the water inlet end is communicated with the upper water outlet end; at the moment, when the upper water outlet end is closed, the water flow still acts on the first sealing position, the switching bolt is kept still, and the lower water outlet end is effectively prevented from being mistakenly sprayed.

Specifically, the switching bolt is of an "i" shape, and includes a switching shaft 61 and a joint 62 connected up and down, wherein the outer diameter of the upper end of the switching shaft is smaller than the outer diameter of the upper end of the joint to ensure that the sectional area of the first sealing position is smaller than the sectional area of the second sealing position, the first sealing position is disposed on the upper end of the switching shaft, the second sealing position is disposed on the outer annular wall of the upper end of the joint, the third sealing position is disposed on the outer annular wall of the lower end of the joint, and the outer diameter of the upper end of the joint is larger than that of the lower end of the joint.
