Description

TECHNICAL FIELD

[0001] The present application relates to a sanitary equipment, in particular to a high-efficiency flushing toilet. BACKGROUND

[0002] The current toilet generally has two water outlet pipes, namely a jet pipe and a brush pipe. The water flow from the water tank drain valve is divided into two parts, one part of the water flow through the brush pipe to wash the inner ring surface of the toilet body, and the other part of the water flow through the jet pipe to spray and flush the bottom of the toilet body. Since the water of the two water outlet pipes comes from the drain valve, and the water level of the brush pipe is higher, the water quantity is difficult to be effectively guaranteed. At the same time, due to the limited height of the water tank, when the water tank is low, the kinetic energy of the water coming out of the water tank is very low, and the flushing effect is not ideal. There are also some low water tank toilets on the market that directly use the water pipe pressure to flush, and the opening and closing are controlled by an electromagnetic valve. This way solves the above problems, but the flushing method requires high water supply to the pipe, and the general water supply pressure needs to be above 2kg to achieve a better flushing effect. SUMMARY

The sewage pipe 11 is preferably a siphon pipe capable of generating siphon during water discharge. The water tank 20 further comprises a water discharge valve 30, a hydraulic drive mechanism 40 connected to the water discharge valve 30 and capable of driving the water discharge valve 30 to discharge water, a water pump 50 for pumping stored water in the water tank 20 to supply the brush pipe 13 for washing, and a water inlet valve 60. Specifically, the water outlet of the water pump 50 is connected to the brush pipe 13 through a hose 17. The water discharge outlet 31 of the water discharge valve is connected to the jet pipe 12. The hydraulic drive mechanism 40 has a hydraulic chamber 43, a water inlet 41 capable of communicating with the hydraulic chamber, and a water outlet 42. The water inlet 41 is connected to an external pressure water source through an opening valve 61, and the water outlet 42 is connected to the outlet of the jet pipe 12. When the opening valve 61 is opened, the external pressure water source flows into the water inlet 41, the hydraulic drive mechanism 40 drives the water discharge valve to open the water discharge outlet 31 for water discharge, and the external pressure water source flows out of the water outlet 42. Finally, the water discharged from the water discharge outlet 31 is sprayed out of the outlet of the jet pipe 12 together with the water flowing out of the water outlet 42. In this embodiment, the bottom wall of the water tank is provided with a waterway connector, the water outlet 42 is connected to the waterway connector through a hose 16, and a jet connector assembly 14 is installed near the outlet of the jet pipe 12, which is connected to the waterway connector through a hose 15.

[0029] The toilet is preferably a smart toilet, which has a master control unit. The opening valve is electrically connected to the master control unit, so that the opening and closing of the opening valve are controlled by the master control unit. The water pump is also electrically connected to the master control unit, and preferably the opening of the opening valve is controlled by the master control unit to be delayed relative to the operation of the water pump.

[0030] The water inlet valve 60 has an inlet 62 connected to the external pressure water source, a first outlet 63 for supplying water into the water tank, and a second outlet 64 connected to the opening valve 61. The water outlet of the first outlet 63 is controlled by a float 65. The second outlet 64 is connected to the water inlet 41 through a hose 18. The water outlets of the first outlet 63 and the second outlet 64 are independent of each other. When the water outlet of the second outlet 64 is stopped, the water outlet of the first outlet 63 is started.

[0031] In this embodiment, the hydraulic drive mechanism 40 is preferably integrated with the drain valve 30. The hydraulic drive mechanism 40 is disposed above the drain valve 30, such that the housing of the hydraulic drive mechanism 40 is engaged with the housing of the drain valve 30. The hydraulic drive mechanism 40 includes a piston 44 disposed within a hydraulic chamber 43 and a connecting rod 45 that is coupled to the piston 44. The connecting rod 45 is coupled to the seal assembly 32 of the drain valve so that movement of the piston 44 drives movement of the seal assembly 32 of the drain valve.

[0032] The hydraulic drive mechanism 40 in this embodiment also includes a pressure control valve for opening the water outlet 42 under a certain pressure. The pressure control valve is configured so that the water outlet 42 is opened only after the hydraulic drive mechanism 40 drives the drain valve 31 to open. The pressure control valve includes a valve body 70 having an inlet end 71 and an outlet end 72. The inlet end 71 communicates with the hydraulic chamber 43, and the outlet end 72 communicates with the outlet 42. A valve port 73 is provided within the valve body 70. The opening and closing of the valve port 73 controls the connection between the inlet end 71 and the outlet end 72. The valve body 70 also includes a valve core 74, a back pressure chamber 75, and a pressure relief hole 76 connected to the back pressure chamber 75. The valve core 74 controls the opening and closing of the valve port 73 under the action of the back pressure of the back pressure chamber 75. The valve core has a water inlet hole 77 connecting the water inlet end 71 and the back pressure chamber 75. Under a certain pressure, the water at the water inlet end 71 enters the back pressure chamber 75 through the water inlet hole 77, and the water in the back pressure chamber 75 is discharged through the pressure relief hole 76, thereby reducing the pressure in the back pressure chamber 75. The valve core 74 opens the valve port 73 under the action of the water inlet pressure, so that the water at the water inlet end 71 can flow to the water outlet end 72.

[0033] Of course, the drain valve can also be button-controlled. The hydraulic drive mechanism includes a piston arranged in the hydraulic chamber and a push rod linked to the piston. The push rod is pressed by the piston to press the drain valve button.

[0034] The external pressure water source is preferably water from a municipal water supply network or water drawn from or outside a water tank by a pump.

[0035] The water flowing out of the first outlet 63 of the water inlet valve 60 is stored in the toilet tank 20. The water flowing out of the second outlet 64 of the water inlet valve 60 flows to the outlet of the jetting pipe 12 after the waterway valve 30 is opened by the hydraulic drive mechanism 40. After the water storage in the toilet tank 20 is completed, if flushing is needed, the water in the toilet tank 20 is first pumped out by the water pump 50 to supply the flushing pipe 13 for cleaning the toilet bowl. After a few seconds, the opening valve 61 is opened, and the tap water flows into the hydraulic chamber 43 of the hydraulic drive mechanism 40, and pushes the waterway valve 30 to open the waterway 31. The water in the toilet tank 20 flows to the outlet of the jetting pipe 12. After the waterway valve 30 is opened, the pressure control valve 70 is opened, and the tap water is guided to the outlet of the jetting pipe 12. The two water flows flow to the toilet bowl together, and the flushing is completed. During the whole flushing period, the first outlet 63 of the water inlet valve 60 is not opened. After the flushing is completed, the float 65 of the water inlet valve 60 falls, and the water is stored in the toilet tank 20.
