Mixed water yielding device and method for adjusting TDS (Total Dissolved Solid) value of mixed yielding water

The invention relates to the field of water purification and discloses a mixed water yielding device and a method for adjusting a TDS (Total Dissolved Solid) value of mixed yielding water. The mixed water yielding device comprises a reverse osmosis water purifying machine (5), a water cleaning machine (6) and a water outlet pipe (4), wherein a water outlet of the reverse osmosis water purifying machine (5) and a water outlet of the water cleaning machine (6) are respectively connected with a first throttle valve (31) and a second throttle valve (32), the first throttle valve (31) and the second throttle valve (32) are respectively connected with a first flowmeter (21) and a second flowmeter (22), and a TDS probe (1) is arranged on the water outlet pipe (4) and is used for probing the TDS value of water in the water outlet pipe (4). According to the mixed water yielding device and the method for adjusting the TDS value of the mixed yielding water, by adopting the technical scheme, clean water yielded from the water cleaning machine and pure water yielded from the reverse osmosis water purifying machine are mixed, and the water quality information of drinking water is clear, so that the demands of customers on personalized drinking water can be met; and on the other hand, the device is simple in structure, low in cost and easy to implement.
