Preferably, as shown in fig. 1 to 4, the first pure water channel 171 of the present invention has a volume of 68.3 cubic meters.

With the increasing of the volume of the first pure water channel 171, the processing difficulty of the water channel plate 1 is increased, and the volume of the water channel plate 1 is increased correspondingly, which finally increases the processing cost, so that the volume of the first pure water channel 171 is preferably set to 68.3 cubic meters in order to ensure that the TDS value in the first pure water channel 171 is reduced and the volume and the manufacturing cost of the water channel plate are increased as little as possible.

Preferably, as shown in fig. 1 to 4, the first filter element 31 of the present invention is a composite filter element.

Because composite filter element is the filter core set with one kind or several kinds of independent functions on a filter core, exert respective effect simultaneously, have the filtration efficiency height, can form the complementary characteristic of advantage between the different filter cores, consequently, regard composite filter element as water purification system's first filter core 31, can filter the great impurity of most in the raw water, can also adsorb the peculiar smell in the raw water simultaneously.

Preferably, the utility model discloses a still be provided with TDS (Total dispersed Solids) sensor 7 on the water route board, TDS sensor 7 with second pure water course 172 communicates, TDS sensor 7 is used for detecting the TDS value of rivers in second pure water course 172.

TDS sensor 7 sets up to communicate with second pure water course 172, through the TDS value change that detects rivers in second pure water course 172, judges the efficiency and the life-span of filter membrane in second filter core 32 to decide whether second filter core 32 needs in time to change.

Preferably, the utility model discloses a still be provided with high voltage switch 8 on the water route board 1, high voltage switch 8 with second pure water course 172 communicates.

By means of the arrangement, the pressure value in the second pure water channel 172 can be monitored in real time, when pure water is filled in the second pure water channel 172, the pressure value reaches the preset highest value, at the moment, the high-voltage switch 8 cuts off the power supply of the water purifier, the water purifier stops running, and the raw water port 151 stops water supplement; when the pressure value is lower than the preset minimum value, the high-voltage switch 8 is connected to the power supply of the water purifier, so that the water purifier is restarted, and the raw water port 151 starts to supplement water.

It should be noted that, along with high-voltage switch 8, the water purifier will also be provided with a low-voltage switch, when the water in second pure water channel 172 gradually decreases, the internal pressure value gradually decreases, and when the pressure value detected by the low-voltage switch is lower than the preset minimum value, the low-voltage switch will also disconnect the power supply of the water purifier, so that the water purifier stops running to prevent booster pump 2 from idling, thereby protecting the water purifier.

Preferably, as shown in fig. 1 to 4, the second filter element 32 of the present invention is an RO (Reverse Osmosis) filter element.

Because the aperture of RO reverse osmosis filter core has reached 0.1 nanometer, make it can filter organic impurity such as aquatic bacterium, virus, heavy metal, set up second filter core 32 into the RO filter core, can play the supplementary effect well to leading composite filter core, filter out in the water purification by composite filter core can't filter out such as heavy metal ion, bacterium, virus micro substance.

So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
