During the operation of the water supply mechanism of the present invention, the water supply pump draws tap water, and the tap water enters the water treatment tank through the water inlet solenoid valve. The coarse filter screen filters large impurities in the water, and the fine filter screen filters small impurities in the water. The filtered water enters the softening water filter element, and the exchangeable sodium ions on the ion resin are exchanged with the calcium and magnesium ions in the water.

After cleaning is completed, the flushing pump draws a salt solution with a high concentration of sodium ions, and the salt solution flows through the ion resin, replacing the calcium and magnesium ions on the ion resin again, restoring the softening ability of the ion resin. In this process, the calcium and magnesium ions are eluted from the ion resin and discharged into the sewage tank with the brine. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] By setting up the water supply mechanism 1, it is convenient to soften and filter the tap water. The treated water enters the secondary filtering device 2, and the secondary filtering device 2 filters the water again to remove fine impurities in the tap water. The filtered water enters the inside of the insulated water tank 9, and the circulation pump 10 draws the water inside the insulated water tank 9 into the air energy heat pump 11.
