In the preferred embodiment of the present invention, the water softening device 2 comprises an outer case 21, a mesh 22, and a softener resin 23; wherein, outer box 21 and mesh 22 all adopt stainless steel to make and form to guarantee can not influence quality of water because of rustting in the use.
A second assembly chamber 211 is formed in the outer case 21 to conveniently accommodate the mesh 22; said mesh 22 is mounted within said second assembly chamber 211 and divides said second assembly chamber 211 into a plurality of small compartments 2111 through said mesh 22; the softener resin 23 is filled in the small compartment 2111; a second water inlet passage 212 formed at the top of the outer case 21 to communicate with the second assembling chamber 211, for supplying water to be softened into the soft water treating device 2 through the second water inlet passage 212; a third water outlet passage 213 communicated with the second assembling chamber 211 is formed at the lower end of the outer case 21 to deliver the softened water through the third water outlet passage 213.
