[0061] In the initial water discharge state of the water discharge device, Figure 3:When the control mechanism is turned on, water flows in along the side of the waterway sliding switch device, and the sliding sleeve 21, under the action of the spring force of the reset elastic body, the sealing part on the sliding sleeve 21 blocks the upper waterway water outlet (upper water outlet sealing surface) of the shaft sleeve. At this time, the head shower outlet is closed, and water flows through the inner cavity of the sealing sleeve, and the hand-held shower discharges water. Water shut-off and reset: When the top shower discharges water, the control mechanism of the faucet body is closed, the faucet stops water, the water pressure above the sealing part of the sliding sleeve 21 disappears, and the sliding sleeve 21 moves upward under the elastic force of the reset elastic body, blocking the upper waterway water outlet of the shaft sleeve, opening the lower waterway water outlet on the sealing sleeve, and restoring the default hand-held shower discharge; when the hand-held shower discharges water, the sliding sleeve 21 remains in this position under the elastic force of the reset elastic body when the water is turned off, and maintains the initial state. During the switching process, the lever slides, driving the sliding sleeve 21 to slide, and the sealing part switches to block the upper and lower water diversion outlets; secondly, during the switching process, the operating force needs to mainly overcome the pressure of the water pressure acting on the sliding sleeve 21 and the sealing part. Because a through hole is arranged in the middle of the sliding sleeve 21, and a force-bearing component is arranged in the through hole, the water pressure on the force-bearing component is limited by the limiting mechanism of the valve body component, and the sliding sleeve can slide relative to the force-bearing component, so there is no action on the sliding sleeve 21, which greatly reduces the water pressure area on the sliding sleeve 21. At this time, the water pressure is small, and labor-saving switching is achieved.
