The pipeline between the booster pump 6 and the water storage pressure barrel 12 is provided with a third solenoid valve 8 and a high-pressure switch 11 in sequence along the water delivery direction. The reverse osmosis membrane 9 is provided with a waste water outlet and a pure water outlet. The pure water outlet is connected to the pipeline between the third solenoid valve 8 and the high-pressure switch 11 through a bypass pipeline. The bypass pipeline is provided with a first one-way valve 10, and the first one-way valve 10 is connected from the pure water outlet to the pipeline between the third solenoid valve 8 and the high-pressure switch 11.

[0020] The upper part of the water storage pressure barrel 12 is connected to the input end of the ultraviolet sterilization module 15 through a pipeline, and the pipeline between the water storage pressure barrel 12 and the ultraviolet sterilization module 15 is provided with a second carbon rod filter element 13, and the pipeline at the input end of the ultraviolet sterilization module 15 is provided with a water outlet TDS probe 14.

[0021] like Figure 1 As shown, the working principle of the automatic sterilization water purification system is as follows:

[0022] Water production working principle

[0023] When the system starts to make water, the source water enters from the water inlet and passes through the first PP cotton filter element 1, the first carbon rod filter element 2 and the second PP cotton filter element 3 to remove particulate matter and residual chlorine impurities in the water. The low-pressure switch 4 sensor ensures that the water pressure of the water source meets the standard to avoid the system idling without water.

[0024] At this time, the first solenoid valve 5 is opened, the booster pump 6 is in working state, the second solenoid valve 7 is opened, and the pressurized water enters the reverse osmosis membrane 9. Under the action of the reverse osmosis membrane 9, the pressurized water is divided into two pipelines of pure water and concentrated wastewater for output. The wastewater is discharged through the wastewater ratio in the wastewater pipeline.

[0025] The purified water passes through the first one-way valve 10 of the bypass pipeline, and the high-pressure switch 11 provides a water pressure control signal, which makes the system stop making water after the purified water is full. The purified water passes through the second carbon rod filter 13 to improve the taste. The outlet TDS probe 14 sensor reads the TDS value of the purified water. After being sterilized by the ultraviolet sterilization module 15, hygienic and safe purified water is supplied.

[0026] Internal automatic sterilization principle

[0027] When the system enters the sterilization state, the first solenoid valve 5 and the second solenoid valve 7 are closed, the booster pump 6 is started, the third solenoid valve 8 and the fourth solenoid valve 16 are opened, and water enters the water storage pressure barrel 12 from the output end of the booster pump 6 through the third solenoid valve 8, and then passes through the second carbon rod filter element and the ultraviolet sterilization module 15. The bacteria in the water are effectively removed, and the water flows back from the reflux pipeline through the fourth solenoid valve 16 and the second one-way valve 17 and returns to the input end of the booster pump 6.

[0028] Repeat the above circulation flow sterilization process to continuously reduce the bacterial concentration in the pure water until it approaches zero.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
