5. The waterway control mechanism of claim 2, wherein the main body further forms a flow regulating chamber communicating with the water inlet channel, the flow control assembly comprises a flow control valve core, the flow control valve core is provided with a regulating part extending into the flow regulating chamber and a driving part positioned outside the flow regulating chamber, and the regulating part changes the flow cross-sectional area of the flow regulating chamber when rotating in the flow regulating chamber, so as to change the flow cross-sectional area of the water inlet channel.
6. The waterway control mechanism of claim 5, wherein the control switch is provided with a first tooth portion, the driving portion of the flow control valve core is provided with a second tooth portion engaged with the first tooth portion, and the control switch rotates to drive the flow control valve core to rotate through the engagement of the first tooth portion and the second tooth portion so as to change the flow cross-sectional area of the flow regulation cavity.
7. The waterway control mechanism of claim 5, wherein the flow regulating chamber is located upstream of the diversion chamber.
8. The waterway control mechanism of claim 1, further comprising a limiting structure for limiting rotation of the control switch, wherein the limiting structure controls the control switch to rotate within a predetermined range; and a second reset elastic piece which resets after the control switch is pressed is also arranged between the control switch and the body.
9. The waterway control mechanism of claim 1, further comprising a positioning structure for rotationally positioning the control switch, the positioning structure controlling the control switch to be positioned at an adjustment position.
10. A shower head comprises a handle and a shower head which are connected, and is characterized by further comprising the waterway control mechanism of any one of claims 1 to 9, wherein the waterway control mechanism is arranged on the handle, the control switch slides along the radial direction of the handle, and the pressing type waterway switching component and the flow control component are arranged in parallel along the axial direction of the handle.
