[0037] Working principle of an integrated water purification equipment:

[0038] When using direct drinking water, the pressure pump 3 is started.

[0039] The water after ultrafiltration flows to the interior of the second fixed cylinder 15 through the first connecting pipe 4, the pressure pump 3, and the fifth connecting pipe 19 in sequence. The pressure pump 3 will pressurize the interior of the second fixed cylinder 15. Under high pressure, the water will pass through the reverse osmosis membrane 26 to achieve reverse osmosis filtration of the water. The water after reverse osmosis filtration enters the interior of the activated carbon filter 17 through the fourth connecting pipe 16, and is processed again by the activated carbon filter 17. The output end of the activated carbon filter 17 outputs the water through the direct drinking water outlet pipe 18 to achieve the outflow of direct drinking water.

[0040] Then, the controller 2 controls the second solenoid valve 13 to open, and the high ion concentration water above the reverse osmosis membrane 26 is transported to the interior of the stabilizing tank 11 through the third connecting pipe 14 to supply domestic water. When the water level is lower than the water level sensor 25, the water level sensor 25 sends a signal to the controller 2, and the controller 2 controls the first solenoid valve 9 to open, and the second connecting pipe 10 transports the filtered water inside the first fixed cylinder 6 to the interior of the stabilizing tank 11 as a supplement.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
