[0038] Referring to Figure 4 The difference between the embodiment and the embodiment 2 is that the first vacuum breaking device 9 is connected downstream of the outlet of the switching device 2, and the second vacuum breaking device 8 is connected downstream of the outlet of the valve B7 based on the embodiment 2.

[0039] Embodiment 4

[0040] In the embodiment, the valve A1 and the switching device 2 are combined into a combined valve 20 based on the embodiment 3, and the float ball 31 can control the opening and closing of the valve A1 and the switching device 2. Specifically, referring to Figures 5 to 15In the embodiment, the combination valve 20 is provided with a water inlet 201 connected with the main water inlet 10, a JET side outlet 202 connected with the toilet flushing water path, a RIM side outlet 203, and a water tank water supplement outlet 208 connected with the water tank 3. The combination valve 20 is provided with a switching cavity 204. The water inlet 201 and the switching cavity 204 are provided with a valve A1. The switching cavity 204 is movably provided with a switching valve core 21. The switching cavity 204 and the toilet flushing water path are provided with a valve seat A206. The switching cavity 204 and the water tank water supplement outlet 208 are provided with a valve seat B207. The switching valve core 21 is arranged between the valve seat A206 and the valve seat B207. The switching cavity 204 is provided with a connecting rod 33 for driving the switching valve core 21 to move up and down. The floating ball 31 is connected with the connecting rod 33 through a rotating shaft A32. The floating ball 31 is provided with a floating ball handle 311. The floating ball handle 311 controls the valve A1 to open through a rotating shaft B312. In addition, the water inlet 201 and the valve A1 are further provided with a detachable filter screen 205.

[0041] Further, in the embodiment, the switching valve core 21 is movably provided with a one-way device 211 for sealing or opening an intermediate hole of the switching valve core 21. When the switching valve core 21 seals the valve seat A206, the water inlet 201 and the water tank water supplement outlet 208 are communicated. The one-way device 211 in the switching valve core 21 is opened and separated from the intermediate hole of the switching valve core 21, so that the water inlet 201 and the switching valve core 21 are communicated. According to the size ratio of the intermediate hole of the switching valve core 21 and the water tank water supplement outlet 208, water is discharged. The one-way device 211 is provided with a sealing head at one end facing the valve seat B207. The toilet flushing is generally as follows: first, the RIM side is brushed, then the JET side is flushed, and finally, the RIM side is brushed to fill the water seal of the toilet. Therefore, in the embodiment, the function of the one-way device 211 is as follows: when the water tank 3 and the water pump 4 normally work to flush the RIM side and the JET side, the water in the water tank 3 is basically used up and needs to be supplemented. At this time, the floating ball 31 is lowered to the bottom, the switching valve core 21 is switched to the valve seat A206, the water tank water supplement outlet 208 is opened, the valve A1 is opened, and the water tank 3 is supplemented with water. Since the switching valve core 21 is provided with the one-way device 211, the water tank can be supplemented with water through the one-way device. The design can fully utilize the internal pipeline structure, effectively save external pipelines, simplify the structure, and reduce the cost. In addition, the water tank can be effectively reduced in size, and the internal space of the toilet can be reduced. In addition, when the switching valve core 21 is switched to the valve seat B207, the water only flows into the toilet flushing water path. On the one hand, the flushing function is not affected. On the other hand, the water does not flow into the full water tank, so that external water leakage is avoided.

[0042] The working principle of the embodiment is as follows: in the embodiment, the valve A1 and the switching device 2 are combined into one whole, the opening and closing of the switching device 2 and the valve A1 can be simultaneously controlled through the floating ball 31, and a one-way device 211 is arranged on the center through hole in the middle of the switching valve core 21 inside the switching device 2. When the switching valve core 21 is sealed on the valve seat A206, the one-way device 1 is in conduction, and when the switching valve core 21 is sealed on the valve seat B207, the blocking head blocks the center through hole of the switching valve core 21, and the one-way state is simultaneously cut off. The floating ball 31 is connected with the rotating shaft A32, the up and down movement of the floating ball 31 drives the up and down movement of the connecting rod 33 through the rotating shaft A32, and finally the up and down switching of the switching valve core 21 is realized. Meanwhile, the floating ball 31 has a floating ball handle 311, which is manually rotated by the rotating shaft 112 when the floating ball 31 moves, and the valve A1 is opened.

[0043] Embodiment 5

[0044] On the basis of embodiment 4, the valve A1 and the valve B7 can also be manually opened and closed. Referring to Figures 5 to 15 In the embodiment, the valve A1 is provided with a first opening and closing device 11, the first opening and closing device 11 is provided with a valve seat C111 and a manual rotating shaft 112 for blocking or opening the valve seat C111, the manual rotating shaft 112 is provided with a spring 1001, one end of the manual rotating shaft 112 is provided with a sealing element C1002, and the other end is connected with a rotating shaft B312. The valve A1 and the valve B7 are controlled to be opened and closed by a manual handle 100, the valve B7 is provided with a second opening and closing device 71 and a rotating shaft B312, the manual handle 100 is connected with the first opening and closing device 11 and the second opening and closing device 71 through the rotating shaft B312, the second opening and closing device 71 has the same structure as the first opening and closing device 11, and the manual handle 100 controls the valve A1 or the valve B7 to be opened through the rotating shaft B312. In addition, in the embodiment, the manual handle 100 controls the valve A1 and the valve B7 to be opened and closed through the rotating shaft B312, that is, when the rotating shaft B312 is rotated downward, one of the valve A1 and the valve B7 is controlled to be opened, and when the rotating shaft B312 is rotated upward, the other valve is controlled to be opened.

[0045] The working principle of the embodiment is as follows: the manual handle 100 is pressed downward, and then transmitted to the rotating shaft B312. The cam structure on the rotating shaft B312 pushes the manual rotating shaft 112 of the first opening and closing device 11 away from the valve seat C111, and the valve A1 is opened. The spring C can reset the manual rotating shaft 112, and the valve A1 is closed. The valve B7 is opened by pulling up the manual handle 100. In the valve A1, the upper cavity of the diaphragm is communicated with the valve seat C111. When the valve seat C111 is opened, the water in the upper cavity of the diaphragm of the valve A1 flows out from the valve seat C111, and then the valve A1 is opened. The water flowing out from the valve seat C111 directly flows to the outside from the back.
