In the above soft water regeneration structure, the soft water member 200 can soften the water flowing into the soft water chamber 101 from the water supply chamber 102, when the soft water effect of the soft water member 200 is deteriorated, the salt containing member 300 can be used to convey the regenerated salt into the water supply chamber 102, a regenerated salt solution can be formed in the water supply chamber 102, so that the soft water member 200 is regenerated, the first water quality sensor 400 is used to detect the total amount of the soluble solids of the regenerated salt solution in the water supply chamber 102, if the total amount of the soluble solids detected by the first water quality sensor 400 is lower than or equal to the regeneration threshold, the regeneration effect of the soft water member 200 is poor, the regenerated salt needs to be continuously conveyed to the water supply chamber 102, so as to improve the regeneration effect of the soft water member 200, when the total amount of the soluble solids detected by the first water quality sensor 400 is higher than the regeneration threshold, the regeneration effect of the soft water member 200 is better, at this time, the salt containing member 300 is closed, while the better regeneration effect of the soft water member 200 is ensured, the waste of regenerated salt is reduced.
Wherein the salt container 300 is in a normally closed state, and when the water softener 200 needs to be regenerated, the salt container 300 is opened and delivers the regenerated salt to the water supply chamber 102.
Wherein, the regenerated salt output by the salt container 300 can be solid or liquid, and the solid needs to be mixed with water to form regenerated salt solution; the liquid is mixed with water to form a regenerated salt solution. The regenerating salt solution is used to regenerate the soft water member 200.
Wherein the "regeneration threshold" may be a total amount of dissolved solids of the regenerated salt solution that enables the regeneration of the soft water element 200; or "regeneration threshold" may be the total amount of dissolved solids of the regeneration salt solution that enables the soft water member 200 to have a better regeneration effect.
In this embodiment, the first water quality sensor 400 is a TDS probe, and the TDS (total Dissolved solids) value of the liquid in the water supply chamber 102, i.e., the total Dissolved solids amount, can be obtained by immersing the TDS probe in the liquid in the water supply chamber 102. In other embodiments, the first water quality sensor 400 can also be used to detect the ionic concentration or the organic concentration of the liquid in the water supply chamber 102.
