Technical Field
The invention relates to the field of water softening treatment devices, in particular to a salt deficiency alarm and a water softening treatment device.
Background
The water softener is widely applied to the treatment of domestic water, and the water softener is mainly used for reducing the hardness of water. The hardness of water is mainly formed by calcium ions and magnesium ions in water, and the water softener generally uses sodium resin to replace the calcium ions and the magnesium ions in water. When the resin absorbs a certain amount of calcium ions and magnesium ions, the efficiency of the resin for replacing the calcium ions and the magnesium ions is gradually reduced, and the resin needs to be regenerated. The regeneration process of the resin is to make sodium chloride (NaCl) solution containing a large amount of sodium ions pass through the failed resin layer, so that calcium ions and magnesium ions in the ion exchange resin are exchanged into the solution, and the sodium ions are adsorbed by the resin, so that the exchange capacity of the resin is restored again. Under the general condition, sodium chloride (NaCl) solution holds in the salt case, and along with the consumption of sodium chloride (NaCl) solution, the sodium ion in the salt case can constantly reduce, after sodium ion reduces to a certain degree, needs the user to supply salt in the salt case in time to guarantee that sodium ion's concentration can regeneration resin.
Most of water treatment devices used in the market at present are full-automatic water treatment devices, generally do not need user operation, but need users to supplement salt regularly, but the users can not know the service condition of the salt in the salt box, so that the salt can be supplemented insufficiently in time, and a proper salt shortage alarm is needed to remind the users whether salt needs to be supplemented in the salt box or not in time.
Typically, a salt-deficiency alarm includes a control device and a sensor, which are connected by a wire. The limitation of the length of the wire leads to various problems, such as the wire binding the sensor, thereby causing inflexible changes in the relative position between the control device and the sensor, and the corrosiveness of the saline solution corroding the wire, thereby causing no transmission of signals between the sensor and the control device; moreover, due to the influence of factors such as salt bridges, salt liquid crystals and impurities in salt boxes, the fault rate of products of infrared distance measurement, ultrasonic distance measurement and the like is high, so that the utilization rate of the salt deficiency alarm is not high at present.
