Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

A water-saving toilet tank, as shown in Figures 1-8, includes a toilet tank 2, the upper end of the toilet tank 2 has a tank cover 1, and the lower end of the toilet tank 2 is centered with a toilet tank water outlet 16, which is located on the side of the toilet tank water outlet 16 The lower end of the toilet water tank 2 is provided with a tap water inlet 14 and a waste water inlet 15 at intervals, and the upper end of the tap water inlet 14 and the waste water inlet 15 extends into the toilet water tank 2 and is buckled with a water inlet valve cover 17 at its upper end; 2. A water storage tank 18 is hung on the wall above. The water storage tank 18 is used to collect and store available waste water resources such as washing and washing clothes. The water storage tank 18 is connected to the waste water inlet 15 through the water pipe a20, and the faucet 19 is passed through the water pipe b 29 Connect tap water inlet 14.

As shown in Fig. 3 and Fig. 4, the toilet tank 2 is provided with a through hole above the water inlet valve cover 17, and the first cylindrical pin 9 is pasted with sealing glue in the through hole, so that the first cylindrical pin 9 can be fixed on the toilet. In the water tank 2; one end of the first connecting rod 3 located in the toilet tank 2 is installed on the first cylindrical pin 9, which can rotate around the first cylindrical pin 9, and the other end of the first connecting rod 3 is connected with a float 4; Tap water inlet 14 and waste water inlet 15 are provided with first spool 7 and second spool 8 movable respectively, and first spool 7 and second spool 8 can be in tap water inlet 14, waste water inlet 15 respectively. Sliding up and down; two through holes are opened on the water inlet valve cover 17, providing guide rails for the first valve core 7 and the second valve core 8 to move up and down, the upper ends of the first valve core 7 and the second valve core 8 Respectively pass through two through holes on the water inlet valve cover 17 and be movably connected with the third connecting rod 6 and one end of the second connecting rod 5 located in the toilet tank 2; the other end of the third connecting rod 6 and the second connecting rod 5 It is flexibly connected with the first connecting rod 3. Preferably, the first connecting rod 3 is connected to one end of the third connecting rod 6 through the second cylindrical pin 10, so that the third connecting rod 6 can rotate around the second cylindrical pin 10, and the other end of the third connecting rod 6 passes through the fourth cylindrical pin 12 Connect the first valve core 7 to make the third connecting rod 6 rotate around the fourth cylindrical pin 12; connect the second connecting rod 5 through the third cylindrical pin 11 in the middle of the first connecting rod 3 so that the second connecting rod 5 can rotate around the fourth cylindrical pin 12. The three cylindrical pins 11 rotate, and the other end of the second connecting rod 5 is connected to the second valve core 8 through the fifth cylindrical pin 13, so that the second connecting rod 5 rotates around the fifth cylindrical pin 13, thus forming a double water inlet linkage mechanism, Wherein, because the third connecting rod 6 and the second connecting rod 5 are installed in different positions on the first connecting rod 3, the stroke of the first spool 7 is smaller than the stroke of the second spool 8, and the float 4 can be adjusted according to the position of the toilet tank 2. The water level inside realizes that waste water first enters the toilet water tank 2, and then tap water and waste water flow into the toilet water tank 2 together, and finally the toilet water tank 2 is filled with water.

As shown in Figure 8, a rubber ring 22 is fixed with glue in the middle of the first spool 7, and a tap water closing plate 23 is fixed at the bottom of the first spool 7, and the tap water closing plate 23 is smaller than the inner diameter of the tap water inlet 14; the second spool 8 A waste water closing plate 25 is fixed at the bottom, and the waste water closing plate 25 is smaller than the inner diameter of the waste water inlet 15 . The upper part of the tap water inlet 14 is provided with a tap water outlet hole 21, so that tap water flows into the toilet tank 2 from the tap water inlet 14. The top of the waste water inlet 15 is provided with a waste water outlet hole 24, and the inner diameter of the waste water outlet hole 24 is greater than the outer diameter of the second valve core 8, so that waste water flows into the toilet tank 2 from the waste water inlet 15. As shown in Figure 4, the lower end and the upper end surface of the water inlet valve cover 17 are all provided with square through holes, so that the water from the first spool 7 and the second spool 8 flows into the toilet tank 2 inside.

As shown in Figure 1, the utility model is also connected with a water pipe c28 between the water pipe b 29 and the water pipe a 20, and an L-type three-way ball valve 26 is installed at the connection between the water pipe c28 and the water pipe b 29; Triangular valve 27 is arranged.

When the water storage tank 18 is stored with waste water, the L-type three-way ball valve 26 is rotated to allow the running water of the water tap 19 to flow into the tap water inlet 14, and the triangular valve 27 is opened to allow the waste water to flow into the waste water inlet 15. As shown in Figure 5, there is some water in the toilet water tank 2 at this moment, after the floating ball 4 is subjected to the buoyancy, it drives the double water inlet linkage mechanism, the rubber ring 22 does not block the tap water outlet hole 21, that is, the tap water inlet 14 conduction, The waste water closing plate 25 does not block the waste water closing plate 25, that is, the waste water inlet 15 is also conducted. As shown in Figure 6, after the floating ball 4 is subjected to buoyancy, it drives the double water inlet linkage mechanism. The tap water closing plate 23 blocks the tap water outlet hole 21, that is, the tap water outlet hole 21 is closed, and tap water cannot enter the toilet tank 2, and the waste water closing plate 25 blocks the waste water outlet hole 24, that is, the waste water outlet hole 24 is closed, and the waste water cannot enter the toilet tank 2 , the water tank is now full of water. As shown in Fig. 7 and Fig. 8, at this time, there is no water in the toilet tank 2, the floating ball 4 has no buoyancy effect, the rubber ring 22 blocks the tap water outlet hole 21, that is, the tap water inlet 14 is closed, and the waste water closing plate 25 does not block the waste water The closing plate 25, that is, the waste water inlet 15 is connected.

Under the situation that storage tank 18 does not store waste water, close triangular valve 27, rotate L-type three-way ball valve 26, make the running water of faucet 19 flow in the waste water inlet 15, guarantee that toilet tank 2 can still normally use when there is no waste water available.

The used valve model of the utility model and manufacturer are as shown in table 1:

Table 1

The utility model pours available waste water resources such as washing and washing clothes into the water storage tank 18 for storage and collection. The water storage tank 18 is connected to the waste water inlet 15 through the water pipe a 20. The water link mechanism controls the flow of the two water inlet valves, so that the available waste water enters the toilet tank 2 first, and then the valve core of the tap water is automatically opened, and the tap water and the available waste water supply water to the toilet tank 2 at the same time, realizing waste water recycling and cooperation The tap water reaches the flushing volume of the toilet water tank, which improves the utilization rate of water resources.

The utility model has been described as an example above. It should be noted that the above embodiments can only be used to further illustrate the utility model, and cannot be interpreted as limiting the scope of protection of the utility model. Without departing from the core of the utility model Under the circumstances, any simple deformation, modification or other equivalent replacements that those skilled in the art can do without creative effort all fall within the protection scope of the present utility model.
