a housing having a brine chamber and a resin chamber, the resin chamber having a first water inlet and a second water inlet in communication with the washer water inlet, wherein the brine chamber is in fluid communication with the resin chamber through the first water inlet;

the diapire in resin chamber is the bellied arc structure that the middle part is upwards, just evenly distributed has first jet orifice on the diapire in resin chamber.

In order to ensure that the water flow has sufficient water pressure before water enters, preferably, an inner container with a hollow inner part is arranged in the shell, a transverse partition plate is arranged in the inner container to partition the inner container into a first cavity and a second cavity which are arranged up and down, the first cavity forms a resin cavity, the partition plate is a bottom plate of the resin cavity, the second cavity forms a water inlet cavity for supplying water to the resin cavity, and the first water inlet and the second water inlet are both arranged on the side wall of the second cavity.

Specifically, the first water inlet and the second water inlet are both strip-shaped openings and are arranged at intervals in the circumferential direction of the side wall of the second cavity.

In order to ensure that the amount of water fed in the circumferential direction is uniform, the lower end surface of the partition plate is preferably a spherical surface.

In order to ensure uniform injection, preferably, the first injection holes are arranged in a radial direction of the partition plate and form one group, and a plurality of groups of the first injection holes are distributed in the circumferential direction of the partition plate.

Preferably, the top of inner bag has uncovered, just uncovered department covers and is equipped with the upper cover, it has the second jet orifice to cover to distribute on the upper cover, just the top wall board of upper cover is the arc structure unanimous with the baffle radian.

Specifically, the periphery of the upper cover and the inner edge of the opening are both provided with a thread structure, and the upper cover and the inner container are detachably connected through the thread structure.

Compared with the prior art, the utility model has the advantages of: this a water softener for cleaning machine, the ascending bellied arc structure in middle part through resin chamber diapire design, make resin chamber diapire when intaking, bellied part produces the pressure differential with other positions, because bellied part, its bottom has bigger water space of depositing, the middle part just has great water pressure relatively naturally, will avoid only intaking from the periphery of diapire like traditional resin chamber when upwards spraying rivers, thereby ensure no matter be to the softening process of hard water or utilize the process of salt solution reduction, rivers can both be even with the resin contact of resin intracavity, and is very practical.
