[0002] In daily use of the toilet, maintaining the height of the water seal is a key step in preventing odor from escaping and maintaining a fresh bathroom environment. After flushing the toilet once, its water seal (i.e. the height of the water surface in the toilet) may decrease. At this time, the water replenishment system will guide part of the water to the toilet seat when the water tank is filled with water to replenish the water seal and ensure that the water seal height is not lower than the standard value, thereby preventing the odor in the toilet from escaping through the lowered water seal and keeping the air in the bathroom fresh.

[0003] Existing toilet water filling devices on the market have problems of dispersed functions and complex structures. On the one hand, the water circuit switching and water filling flow regulation are designed as two independent modules, which not only increases the volume of the equipment and the installation space requirements, but also increases the manufacturing cost; on the other hand, the lack of an effective pressure relief mechanism makes the water filling pipeline susceptible to pressure shock in a high-pressure water supply environment, posing the risk of pipe bursting, further affecting the safety and reliability of toilet use.

[0004] The object of the present invention is to provide a double-row water replenishment device and a double-row water replenishment method. The double-row water replenishment device has switching, flow regulation and pressure relief functions at the same time. The water path switching is achieved by rotating the turntable, and the water replenishment amount and the pressure relief amount are adjusted at the same time by a rotatable adjusting part.

[0010] Furthermore, an adjusting opening connected to the water inlet cavity is provided on the side wall of the adjusting member, and the adjusting opening extends axially along the side wall of the adjusting member. When the adjusting member rotates, the overlapping area of ​​the adjusting opening on the adjusting member and the water replenishment through hole and the pressure relief through hole produces an opposite change trend.

[0011] Furthermore, an adjusting channel is provided in the adjusting member, and the adjusting channel is connected with the water inlet cavity and the adjusting opening, and the water flow in the water inlet cavity flows from the adjusting channel to the adjusting opening.

[0012] Furthermore, the adjusting member is driven to rotate by an external driving device, or is manually driven to rotate.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The present invention provides a double-row water replenishment device, such as Figures 1 to 11 As shown, the water replenisher body 1 includes a water replenisher body 1, which is provided with a water inlet chamber 11, a water replenishment chamber 13 and a pressure relief chamber 15. The water replenishment chamber 13 is located at the front side of the water inlet chamber 11, and the pressure relief chamber 15 is located at the rear side of the water inlet chamber 11. The water replenisher body 1 is also provided with a water inlet 12, a water outlet 14 and a pressure relief port 15 for connecting these chambers with the outside. Water flows into the water inlet chamber 11 from the water inlet 12, and after being divided into the water replenishment chamber 13 and the pressure relief chamber 15, it flows out from the water outlet 14 and the pressure relief port 15. Figure 7 .

[0020] The water replenishment device of the present invention can realize the switching between full-row and half-row water replenishment. Figure 2 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. Figure 3 As shown, the water replenishment chamber 13 is provided with full-row water replenishment holes 131 and half-row water replenishment holes 132. The water path formed by the full-row water replenishment through holes 111 and the full-row water replenishment holes 131 is the full-row water replenishment water path; the water path formed by the half-row water replenishment through holes 112 and the half-row water replenishment holes 132 is the half-row water replenishment water path. The switching of different water replenishment water paths is achieved by a rotating disk 2. Figure 1 and 2 As shown, the turntable 2 is tightly fitted between the water inlet chamber 11 and the water outlet chamber 13. Specifically, the turntable 2 is rotatably arranged on the fixed shaft 18 on the water replenisher body 1. The turntable 2 is an axially symmetrical fan-shaped structure, and a plurality of water holes 21 are provided on the fan surface of the turntable 2. In the present embodiment, the number of the water hole 21 is one, and this water hole 21 is located at the symmetry axis of the turntable 2. The turntable 2 rotates so that the water hole 21 coincides with or is misaligned with the water surfaces of different water replenishment waterways, so as to realize water flow or water cutoff of different water replenishment waterways, that is, when the water hole 21 coincides with the full-row water replenishment through hole 111 and the full-row water replenishment hole 131 (reference Figure 3 ), the full row of water replenishment water channels are open to water, and the half row of water replenishment water channels are closed to water. When the water through hole 21 coincides with the half row of water replenishment through holes 112 and the half row of water replenishment holes 132, the half row of water replenishment water channels are open to water, and the full row of water replenishment water channels are closed to water.

[0021] The water replenishing device of the present invention can realize the function of pressure relief while replenishing water. Figure 2As shown, the water inlet chamber 11 is provided with a full-discharge pressure through hole 113 and a half-discharge pressure through hole 114 leading to the pressure relief chamber 15. The water paths from the full-discharge pressure through hole 113 and the half-discharge pressure through hole 114 to the pressure relief chamber 15 are respectively the full-discharge pressure water path and the half-discharge pressure water path. During the water replenishment process, the water flow in the water inlet chamber 11 can be diverted to the water replenishment chamber 13 and the pressure relief chamber 15 through the water replenishment through hole and the pressure relief through hole thereon, and then flow out through the water outlet 14 and the pressure relief port 16. The water outlet 14 guides the water flow in the water replenishment chamber 13 to the toilet to replenish the toilet, and the pressure relief port 16 guides the water flow in the pressure relief chamber 15 into the toilet tank.

[0022] In order to adjust the water replenishment flow and the pressure relief flow, the present design sets a rotatable adjusting member in the water inlet chamber 11, and the adjusting member is preferably a rotating shaft 3 structure. Figure 1 As shown, the water replenisher body 1 is provided with a mounting hole 17 for fixing the rotating shaft 3, and the rotating shaft 3 is rotatably arranged in the mounting hole 17 and extends to the water inlet cavity 11. Figure 4 As shown, it is a three-dimensional diagram of the rotating shaft 3. A buckle 33 is provided at the bottom of the rotating shaft 3. The buckle 33 is engaged with the annular step groove 191 at the bottom of the water replenisher body 1. Figure 5 and Figure 7 , install the rotating shaft 3 on the water replenisher body 1.

[0023] like Figure 4 As shown, an adjustment opening 31 is provided on the side wall of the rotating shaft 3, and the adjustment opening 31 extends axially along the side wall of the rotating shaft 3 to form an upper adjustment opening 312 and a lower adjustment opening 311. An adjustment channel 32 connecting the water inlet chamber 11 and the adjustment opening 31 is provided in the middle of the rotating shaft 3, and the water in the water inlet chamber 11 flows from the adjustment channel 32 to the adjustment opening 31.

[0024] There are two rotating shafts 3, namely, a full-row rotating shaft 3-1 and a half-row rotating shaft 3-2. The full-row rotating shaft 3-1 corresponds to the full-row water replenishment through hole 111 and the full-row pressure relief through hole 113, and the half-row rotating shaft 3-2 corresponds to the half-row water replenishment through hole 112 and the full-row pressure relief through hole 114. Figure 6 , where (2) is the water replenishment amount adjustment state diagram, and (3) is the pressure relief amount adjustment state diagram. The rotation of the shaft 3 causes the adjustment opening 31 thereon to have an opposite change trend with the overlapping area of ​​the corresponding water replenishment through hole and the pressure relief through hole, thereby causing an opposite change trend in the sizes of the water flow sections of the two, that is, when the water flow section of the water replenishment waterway increases, the water flow section of the pressure relief waterway decreases; conversely, when the water flow section of the water replenishment waterway decreases, the water flow section of the pressure relief waterway increases. In this way, the flow rate of the water replenishment chamber 13 and the pressure relief chamber 15 can be adjusted, and while meeting the water replenishment demand, the pressure can be effectively relieved to ensure the stable operation of the toilet water replenishment system.

[0025] like Figure 6As shown in the rotating shaft 3-1 in the figure, when the lower regulating opening 311 completely overlaps with the water replenishment through hole, the water replenishment flow is the largest, and the pressure relief flow is the smallest; the rotating shaft 3 rotates, so that the overlapping area of ​​the lower regulating opening 311 and the water replenishment through hole gradually decreases, and the overlapping area of ​​the upper regulating opening 312 and the pressure relief through hole gradually increases, that is, the water replenishment flow gradually decreases, and the pressure relief flow gradually increases; the rotating shaft 3 continues to rotate until the lower regulating opening 311 completely avoids the water replenishment through hole, Figure 6 As shown in the rotating shaft 3-2, after the water flows through the regulating channel 32, the lower regulating opening 311 and the upper regulating opening 312, it all flows to the pressure relief hole and enters the pressure relief chamber 15. At this time, the water replenishment flow is the smallest and the pressure relief flow is the largest, which can prevent the water replenisher body and the water inlet valve from maintaining pressure and causing the water pipe to burst.

[0026] The rotating shaft 3 of the present invention can be driven to rotate by an external driving device, or the rotating shaft 3 can be driven to rotate manually. Figure 1 As shown, the water replenisher body 1 is provided with an indicator mark 8 for indicating the state of the rotating shaft 3. The indicator mark 8 is presented in the form of an adjustment scale, which is not only intuitive and easy to read, but also can accurately reflect the current state or position of the rotating shaft 3. The user only needs to simply observe the adjustment scale to quickly understand and adjust the rotating shaft 3 to the desired state.

[0027] Figure 8 Schematic diagram of the water replenishment device of the present invention on the drain valve 4, the water replenishment device body 1 is installed on the drain valve 4 and connected to the button body 41. Fig. 9 As shown, a mounting seat 7 is provided on the shell of the drain valve 4, and a slot 71 is provided on the mounting seat 7. A hook 19 is provided at the bottom of the water replenisher body 1, and the hook 19 cooperates with the slot 71 to mount the water replenisher body 1 on the drain valve 4.

[0028] After the water replenishment device 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, and 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 replenishment pipe 5, and the overflow pipe 44 is connected to the water seal through the internal water channel of the toilet, so that the replenishment water of the water inlet valve can flow to the water seal of the toilet through the drain valve 4 with a diverter pressure relief water replenisher, and the pressure relief port 16 of the pressure relief chamber 15 is connected to the toilet water tank.

[0029] The turntable 2 is connected to the switch button of the drain valve 4 and is driven to rotate by the switch button. Figure 3As shown, two driving rods are axially arranged on the turntable 2, the half-drain driving rod 23 is connected to the half-drain button 43 of the drain valve 4, and the full-drain driving rod 22 is connected to the full-drain button 42 of the drain valve 4. When the user presses the button of the drain valve to flush the toilet, the pressed button will apply force to the corresponding driving rod to make it move in a circle, and the driving rod will drive the turntable 2 to rotate left and right to switch the full-drain water supply waterway and the half-drain water supply waterway to supply water to the toilet.

[0030] 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 1 The water inlet 12, water outlet 14, water inlet chamber 11 and pressure relief chamber 15 are all arranged on the middle shell 1-2. The rear shell 1-3 covers the rear side of the middle shell 1-2 to close the water inlet chamber 11 and the pressure relief chamber 15. The bottom of the pressure relief chamber 15 is provided with a pressure relief port 16. Figure 1 The water replenishment chamber 13 is arranged on the front shell 1-1, and the water replenishment chamber 13 is connected with the water outlet 14. The turntable 2 is arranged between the front shell 1-1 and the middle shell 1-2. The front shell 1-1 is provided with a clearance groove 192 for avoiding the driving rod on the turntable 2. The driving shaft of the turntable 2 extends from the turntable 2 through the clearance groove 192 of the front shell 1-1 to the drain valve 4.

[0031] 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.

[0032] The double-row water replenishment method of the present invention is as follows: like Fig.10 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 left through the full drain drive rod 22, and the water hole 21 conducts the full drain water supply water circuit, and the water flows into the water inlet chamber 11 from the water inlet 12, and then enters the water supply chamber 13 and the pressure relief chamber 15 respectively through the full drain water supply water circuit and the full drain pressure water circuit, the water in the water supply chamber 13 flows into the overflow pipe 44 of the drain valve 4 from the water outlet 14, and the water in the pressure relief chamber 15 flows to the toilet water tank from the pressure relief port 16 to achieve pressure relief.

[0033] Before and after pressing the full-drain button 42, the water flow section of the full-drain water supply waterway and the full-drain pressure waterway can be adjusted by rotating the full-drain shaft 3-1 to adjust the water flow rate and the pressure relief flow rate. Before pressing the button of the drain valve 4, first rotate the full-drain shaft 3-1 to the desired diversion position, and then press the button to perform the drainage and water supply operation. The water flow sequence of the waterway is: water inlet → shaft (adjusting the water supply amount) → turntable 2 (switching the waterway) → water outlet. After pressing the full-drain button 42, rotate the full-drain shaft 3-1 to adjust the flow rate, and the water flow sequence of the waterway is: water inlet → turntable 2 (switching the waterway) → shaft (adjusting the water supply amount) → water outlet.

[0034] like Fig.11 As shown, when the half-drain button 43 of the drain valve 4 is pressed to perform half-drainage, the half-drain button 43 drives the turntable 2 to rotate rightward through the half-drain drive rod 23, the water hole 21 is connected with the half-drain water supply waterway, and the water flows into the water inlet chamber 11 from the water inlet 12, and then enters the water supply chamber 13 and the pressure relief chamber 15 from the half-drain water supply waterway and the half-drain pressure relief waterway respectively. The water in the water supply chamber 13 flows into the overflow pipe 44 of the drain valve 4 from the water outlet 14, and the water in the pressure relief chamber 15 flows to the toilet water tank from the pressure relief port 16 to achieve pressure relief.

[0035] Similarly, before and after pressing the half-row button 43, the water flow rate and the pressure relief flow rate can be adjusted by rotating the half-row rotating shaft 3-2 to adjust the water flow cross-section of the half-row water replenishment waterway and the half-row pressure relief waterway.
