[0037] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] The utility model provides a water supply water channel switching component, such as Figures 1 to 10 As shown, the device comprises a water replenisher body 1, which is provided with a water inlet chamber 11 and a water replenishment chamber 13. The water inlet chamber 11 is provided with a water inlet 12, and the water replenishment chamber 13 is provided with a water outlet 14. The water inlet chamber 11 is connected to the water replenishment chamber 13 via a full-drain water replenishment waterway and a half-drain water replenishment waterway. The replenishment water flow from the drain valve 4 is introduced into the water inlet chamber 11 through the water inlet 12, switches the waterway through a rotary disk 2, is introduced into the water replenishment chamber 13, and then is directed to the overflow pipe 44 of the drain valve 4 through the water outlet 14.

[0039] like Figure 2 and Figure 4 As shown, the turntable 2 is arranged on the water path between the water inlet chamber 11 and the water replenishing chamber 13, and is closely matched with the water inlet chamber 11 and the water replenishing chamber 13. Specifically, as shown in FIG. Figure 2 As shown, the turntable 2 is rotatably arranged on the fixed shaft 15 on the water replenisher body 1. Figure 6 As shown, the turntable 2 has an axially symmetrical sector-shaped structure, with a plurality of water holes 21 defined on the sector surface. In this embodiment, there is only one water hole 21, located at the axis of symmetry of the turntable 2. Rotating the turntable 2 causes this water hole 21 to coincide with or be offset from the water flow surfaces of different water supply channels, thereby enabling or disabling water flow in these channels.

[0040] The turntable 2 is driven by the switch button of the drain valve 4. Figures 6 to 8 As shown, two driving rods are axially provided on the turntable 2, the full-row driving rod 22 is connected to the full-row button 42 of the drain valve 4, and the half-row driving rod 23 is connected to the half-row button 43 of the drain valve 4. The two buttons press the corresponding driving rods downward, and the driving rods drive the turntable 2 to rotate left and right with the axis of the fixed shaft 15 as the center of the circle to realize the switching of the full-row water supply waterway and the half-row water supply waterway.

[0041] Furthermore, if Figure 3 As shown, the water inlet chamber 11 is provided with a full row of water replenishment holes 111 and a half row of water replenishment holes 112; correspondingly, as shown in FIG. Figure 4 and Figure 5As shown, the water replenishment chamber 13 is provided with a full-row water replenishment hole 131 and a half-row water replenishment hole 132. When the turntable 2 rotates until the water hole 21 on it coincides with the full-row water replenishment hole 111 and the full-row water replenishment hole 131 on the chamber body, water flows through the full-row water replenishment waterway and the half-row water replenishment waterway is closed. When the turntable 2 rotates until the water hole 21 on it coincides with the half-row water replenishment hole 112 and the half-row water replenishment hole 132, water flows through the half-row water replenishment waterway and the full-row water replenishment waterway is closed.

[0042] Figure 7 This is a schematic diagram of the state of the water replenisher of the utility model on the drain valve 4. The water replenisher body 1 is installed on the drain valve 4 and connected to the button body 41. Figure 8 As shown, the housing of the drain valve 4 is provided with a mounting seat 7, which is provided with a slot 71. The bottom of the water replenisher body 1 is provided with a buckle 17, which cooperates with the slot 71 to fix the water replenisher body 1 on the drain valve 4. After the water replenisher is installed on the drain valve 4, the water inlet 12 of its water inlet chamber 11 is connected to the water inlet pipe (not shown in the figure) for filling water into the water inlet chamber 11. The water outlet 14 of the water replenishment chamber 13 is connected to the overflow pipe 44 of the drain valve 4 through the water outlet pipe 5. The overflow pipe 44 is connected to the water seal through the internal water channel of the toilet, so that the water replenished by the water inlet valve can flow to the water seal of the toilet through the drain valve 4 with the water replenisher.

[0043] The water replenisher body 1 of the present invention is designed to be composed of a front shell 1-1, a middle shell 1-2, a rear shell 1-3 and a rear shell cover 1-4. Figure 2 Each shell can be directly welded or fixed by bolts and threaded holes. The water inlet 12, water outlet 14, and water inlet chamber 11 are all provided on the middle shell 1-2. The rear shell 1-3 covers the rear side of the middle shell 1-2 to seal the water inlet chamber 11. The water replenishment chamber 13 is provided on the front shell 1-1 and is connected to the water outlet 14. The turntable 2 is provided between the front shell 1-1 and the middle shell 1-2. The front shell 1-1 is provided with a clearance groove 16 for circumventing the drive rod of the turntable 2. The drive shaft of the turntable 2 extends from the turntable 2 through the clearance groove 16 of the front shell 1-1 to the drain valve 4.

[0044] A sealing member, preferably a sealing ring 6, is adaptively provided between each water outlet and the water passage on the water replenishing device of the present invention to improve the sealing performance of the structure and avoid water leakage.

[0045] As a further improvement of the structure, the water replenisher body 1 can also be provided with an adjusting member for adjusting the water flow rate, such as a rotating shaft 3, Figure 2 By rotating the rotating shaft 3, the water flow cross-sectional area of the water supply waterway is gradually increased or decreased to achieve the adjustment of the water flow rate.

[0046] The double-row water replenishing method of the utility model is as follows:

[0047] like Figure 9 As shown, when the full drain button 42 of the drain valve 4 is pressed to fully drain the water: the full drain button 42 drives the turntable 2 to rotate to the left through the full drain drive rod 22 until the water hole 21 coincides with the full drain water replenishment through hole 111 and the full drain water replenishment hole 131. At this time, the full drain water replenishment water path is connected, and the water flows into the water inlet chamber 11 from the water inlet 12, and then enters the water replenishment chamber 13 from the full drain water path. The water in the water replenishment chamber 13 flows into the overflow pipe 44 of the drain valve 4 from the water outlet 14.

[0048] Before and after pressing the full row button 42, the opening size of the full row water replenishment through hole 111 can be adjusted by rotating the full row rotating shaft 3-1 to achieve the adjustment of the water replenishment flow rate.

[0049] like Figure 10 As shown, when the half-row button 43 of the drain valve 4 is pressed to perform half-draining: the half-row button 43 drives the turntable 2 to rotate right through the half-row drive rod 23, and when the water hole 21 coincides with the half-row water replenishment through hole 112 and the half-row water replenishment hole 132, water is passed through the half-row water replenishment waterway, and the full-row water replenishment waterway is closed. Water flows into the water inlet chamber 11 from the water inlet 12, and then enters the water replenishment chamber 13 from the half-row water replenishment waterway. The water in the water replenishment chamber 13 flows into the overflow pipe 44 of the drain valve 4 from the water outlet 14.

[0050] Similarly, before and after pressing the half-row button 43, the opening size of the half-row water replenishment through hole 112 can be adjusted by rotating the half-row rotating shaft 3-2 to adjust the water replenishment flow rate.
