Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water purification. Specifically, it relates to a drinking water purification device with adjustable TDS content. Background Art

[0002] TDS is the English initialism of Total Dissolved Solids, which refers to the concentration of total dissolved substances in water, with the unit of milligram per liter (mg / L). It mainly reflects the concentration of ions such as Ca2+, Mg2+, Na+, and K+ in water, and has a good corresponding relationship with the water hardness and conductivity. The smaller the TDS value, the lower the concentration of ions such as Ca2+, Mg2+, Na+, and K+ in water, and the smaller the conductivity.

[0003] The TDS value is generally used to measure the purity of pure water. However, a small TDS value does not necessarily mean good water quality, nor does a high TDS value mean poor water quality. The qualified drinking water standard must meet the microbiological indicators (bacterial count), toxicological indicators (concentration of heavy metal ions, etc.), sensory properties (color, smell, taste, visible substances to the naked eye), general chemical indicators, and radioactive indicators. Healthy and clean domestic water should not contain pathogenic microorganisms, and the chemical substances and radioactive substances in the water should not endanger human health, and the sensory properties should be good.

[0004] The existing drinking water purification devices generally directly filter the raw water and then drink it, but cannot control and adjust the TDS content inside, making it difficult to control the concentration of various ions in the purified water, which affects people's body absorption and health.

[0005] To solve the above problems, a drinking water purification device with adjustable TDS content is proposed in this application. Summary of the Utility Model

[0006] In view of the problems in the related art, the utility model proposes a drinking water purification device with adjustable TDS content to overcome the above-mentioned technical problems existing in the related art.

[0009] Preferably, a flow regulating valve is installed between the PPC water purifier and the RO water purifier, and the flow regulating valve is arranged in parallel with the RO water purifier.

[0010] The setting of the flow regulating valve can adjust the re - filtration amount after the rough filtration of the PPC water purifier, thereby being able to adjust the TDS content in the pure water after the RO water purifier filters.

[0011] Preferably, a check valve is installed between the CTO water purifier and the RO water purifier.

[0012] Through the setting of the check valve, it can prevent the water filtered by the RO water purifier from flowing back into the CTO water purifier, affecting the TDS content after the subsequent mixing of the two kinds of water.

[0013] Preferably, a waste water solenoid valve is connected to the original water tank, and the waste water solenoid valve is connected to the RO water purifier.

[0014] Through the setting of the waste water solenoid valve, the waste water filtered by the RO water purifier can flow back into the original water tank through the waste water solenoid valve for storage and then recycled for filtration.

[0015] Preferably, a water discharge solenoid valve is installed between the pure water tank and the CTO water purifier.

[0016] Through the setting of the water discharge solenoid valve, it is convenient to discharge the water source in the pure water tank.

[0017] Preferably, two water level monitors are installed on both the original water tank and the pure water tank, and two of the four water level monitors are respectively installed on the inner bottom walls of the original water tank and the pure water tank.

[0018] Through the setting of the water level monitors, it is convenient to monitor the water levels on the original water tank and the pure water tank, and the water level monitors at the bottom can give an early warning when the water sources in the original water tank and the pure water tank are exhausted.

[0019] In summary, the technical effects and advantages of the present utility model are as follows:

The setting of the flow regulating valve 8 can adjust the re-filtration amount after the rough filtration of the PPC water purifier 4, so as to adjust the TDS content in the pure water filtered by the RO water purifier 5.

[0027] Referring to Figure 1 , a check valve 9 is installed between the CTO water purifier 6 and the RO water purifier 5. Through the setting of the check valve 9, it can prevent the water filtered by the RO water purifier 5 from flowing back into the CTO water purifier 6, affecting the TDS content after the subsequent mixing of the two kinds of water.

[0028] Referring to Figure 1 , a waste water solenoid valve 10 is connected to the raw water tank 1, and the waste water solenoid valve 10 is connected to the RO water purifier 5. Through the setting of the waste water solenoid valve 10, the waste water filtered by the RO water purifier 5 can be returned to the raw water tank 1 through the waste water solenoid valve 10 for storage and re-circulation filtration.

[0029] Referring to Figure 1 , a water discharge solenoid valve 7 is installed between the pure water tank 2 and the CTO water purifier 6. Through the setting of the water discharge solenoid valve 7, it is convenient to discharge the water source in the pure water tank 2.

[0030] Referring to Figure 1 , two water level monitors are installed on both the raw water tank 1 and the pure water tank 2, and two of the four water level monitors are respectively installed on the inner bottom walls of the raw water tank 1 and the pure water tank 2.

[0031] Working principle: During operation, the water in the original water tank 1 is sucked under the action of the self-priming pump 3. After being roughly filtered by the PPC water purifier 4, the water passes through the RO water purifier 5 to obtain pure water in one way, and in another way, it is mixed with the pure water after passing through the flow regulating valve 8. The user sets the required TDS value on the control panel, that is, the adjusted TDS value. The electronic control system automatically adjusts the aperture size of the flow regulating valve 8 according to the values of the raw water TDS and the pure water TDS to adjust the proportion of the mixed water, so as to achieve the adjustment of the TDS. After the water is roughly filtered by the PPC water purifier 4, the water quality has been purified and can be directly drunk.
