[0031] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0032] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a variety of structural modes and implementation modes that can be replaced by those skilled in the art can be replaced with each other. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the invention.

[0033] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0034] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the toilet water supply assembly includes a water inlet pipe 1, a water tank 2, a water pump 3 and a water outlet pipe 4. The water inlet pipe 1 is connected to the water tank 2, and clean water enters the water tank 2 through the water inlet pipe 1. The water tank 2 is connected to the water pump 3, and the water pump 3 is connected to the water outlet pipe 4. The water pump 3 pumps the clean water in the water tank 2 into the water outlet pipe 4. The water tank 2 includes a main water tank 21, an auxiliary water tank 22 and a balancing water pipe 23. The balancing water pipe 23 connects the main water tank 21 and the auxiliary water tank 22. The main water tank 21 is provided with a water inlet and a water outlet. The water inlet pipe 1 is installed at the water inlet, and the water pump 3 is installed at the water outlet.

[0035] The water inlet pipe 1 is connected to an external water source, so that clean water enters the water tank 2 and is stored. When the water in the water tank 2 is needed, the water pump 3 works to pump the clean water in the main water tank 21 into the water outlet pipe 4, and then enters the bowl 20 from the water outlet pipe 4 (see Figure 2 ), flush the dirt in the bowl 20 into the sewage pipe 30 (see Figure 2 )middle.

[0036] As clean water quickly flows from the main water tank 21 into the water outlet pipe 4, the water level of the main water tank 21 drops rapidly. Since the balancing water pipe 23 connects the main water tank 21 and the auxiliary water tank 22, the clean water in the auxiliary water tank 22 flows into the main water tank 21 through the balancing water pipe 23, thereby replenishing the clean water in the main water tank 21.

[0037] In this embodiment, by providing a main water tank 21 and a sub-water tank 22, the water supply volume of the water tank 2 is increased, and the bowl 20 of the toilet can be thoroughly cleaned.

[0038] Furthermore, if Figure 1 and Figure 3 As shown, the water tank 2 further includes a balancing air pipe 24 , which connects the main water tank 21 with the upper part of the auxiliary water tank 22 , and a balancing water pipe 23 connects the main water tank 21 with the lower part of the auxiliary water tank 22 .

[0039] The bottom is connected to a balancing water pipe 23 for balancing the water levels of the two water tanks, and the top is connected to a balancing air pipe 24 for balancing the air pressure in the two water tanks.

[0040] Preferably, if Figure 3 As shown, the diameter of the balancing air pipe 24 is smaller than the diameter of the balancing water pipe 23. Optionally, the inner diameter of the balancing water pipe 23 is greater than 15 mm. The balancing water pipe 23 with a larger diameter allows clean water to quickly enter the main water tank 21 from the auxiliary water tank 22. The balancing air pipe 24 with a smaller diameter makes the air pressure of the main water tank 21 and the auxiliary water tank 22 different in a short time. For example: when the water level in the main water tank 21 drops rapidly, the main water tank 21 is under temporary negative pressure, and the negative pressure can help the water in the auxiliary water tank 22 to quickly enter the main water tank 21, speeding up the flushing speed and making it easier to flush the toilet.

[0041] Furthermore, if Figure 3 As shown, a first atmospheric air inlet 221 is provided at the top of the auxiliary water tank 22. The first atmospheric air inlet 221 is kept in communication with the atmosphere, so that the clean water in the auxiliary water tank 22 can quickly enter the main water tank 21 under the combined action of the atmosphere, its own gravity and the negative pressure of the main water tank 21.

[0042] Furthermore, if Figure 3 As shown, a second atmospheric air inlet 211 is provided on the top of the main water tank 21, and the diameter of the second atmospheric air inlet 211 is less than 5 mm.

[0043] Since the diameter of the second atmospheric air inlet 211 is smaller than that of the first atmospheric air inlet 221, it is insufficient to replenish air to the main water tank 21 in time. Since the balancing air pipe 24 is also thin, air cannot be sucked in from the balancing air pipe 24 in time, thereby forming a negative pressure in the main water tank 21, and the air pressure of the auxiliary water tank 22 is close to the atmospheric pressure, that is, the pressure of the auxiliary water tank 22 is greater than the pressure of the main water tank 21. Under the combined effect of this negative pressure and gravity, the water in the auxiliary water tank 21 enters the main water tank 21 through the balancing water pipe 23. Because the water flow does not rely solely on gravity to make the water levels of the two water tanks equal, the water level of the main water tank 21 is higher than the water level of the auxiliary water tank 22 under the superposition of negative pressure. When the water pump 3 stops working, the negative pressure source disappears, and air enters the main water tank 21 through the balancing air pipe 24 and the second atmospheric air inlet 211, gradually making the pressures of the two water tanks the same, and the water levels remain consistent under the action of gravity.

[0044] Optionally, when the main water tank 21 supplies water, the second atmospheric air inlet 211 can be blocked. The second atmospheric air inlet 211 is completely airtight, and the main water tank 21 is more likely to generate negative pressure. At this time, the diameter of the second atmospheric air inlet 211 can be the same as that of the first atmospheric air inlet 221.

[0045] The second atmospheric air inlet 211 may be blocked manually or automatically.

[0046] Alternatively, see Figure 4 An automatic sealing unit 222 is provided at the second atmospheric air inlet 211. The automatic sealing unit 222 includes a conical sealing tube 222a and sealing beads 222b. The sealing beads 222b are placed in the sealing tube 222a. When the main water tank 21 supplies water, the sealing beads 222b are sucked toward the sealing tube 222a by the negative pressure and block the sealing tube 222a; when the main water tank 21 stops supplying water, the negative pressure disappears, the sealing beads 222b are loosened from the sealing tube 222a, and the blockage is released.

[0047] Optionally, the main water tank 21 may not be provided with the second atmospheric air inlet 211. Furthermore, the main water tank 21 and the auxiliary water tank 22 are larger at the top and smaller at the bottom.

[0048] When designing the appearance of a toilet, it is usually designed to be larger at the top and smaller at the bottom, so that the user can place his legs comfortably without touching the ceramic. Figure 2 As shown, the bottom of the toilet is smaller and the top is larger. For aesthetic reasons, the bottom continues to get smaller so as to form a sense that the toilet is floating in the air, so the bottom of the toilet has a stepped surface. In order to make full use of the space in the toilet, the main water tank 21 and the auxiliary water tank 22 are also designed to be larger at the top and smaller at the bottom.

[0049] In another embodiment of the present invention, Figure 1-2As shown, the toilet includes an external shell 10, a bowl 20 and a sewage pipe 30. The bowl 20 is used to receive waste. An installation space is left between the bottom of the bowl 20 and the external shell 10. The sewage pipe 30 is located in the installation space and connected to the bottom of the bowl 20. The main water tank 21 and the auxiliary water tank 22 are located below the bowl 20.

[0050] The main water tank 21 and the auxiliary water tank 22 utilize the remaining installation space below the bowl 20 to make the volume large enough to increase the water supply volume.

[0051] Furthermore, if Figure 2 As shown, the main water tank 21 and the auxiliary water tank 22 are respectively located on the left and right sides of the sewage pipe 30.

[0052] The "left and right" in the present invention is based on the orientation of the toilet after installation and use. A gap is left between the main water tank 21 and the auxiliary water tank 22, which is convenient for the installation of the main water tank 21 and the auxiliary water tank 22, and leaves space for the sewage pipe 30 or other pipelines.

[0053] Furthermore, if Figure 2 As shown, the outer side surfaces of the main water tank 21 and the auxiliary water tank 22 match the shape of the inner side surface of the external shell 10 .

[0054] In order to increase the water supply volume of the water tank 2 as much as possible, the shapes of the main water tank 21 and the auxiliary water tank 22 are matched and fitted with the shape of the inner surface of the external shell 10 as much as possible.

[0055] The present invention can increase the water tank volume as much as possible without increasing the outer size of the toilet. Moreover, through the configuration of the atmospheric air inlet, the speed of water flowing from the two water tanks to the suction side of the water pump can be increased, so that the water supply effect of the water pump is close to that of the integral water tank.

[0056] The above description is only the principle and preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several other modifications can be made based on the principle of the present invention, which should also be considered as the protection scope of the present invention.
