Further, in the same group of second filter bodies 4, two second filter bodies 4 are arranged symmetrically to each other. As shown in fig. 7, two second filter bodies 4 may be symmetrically arranged with respect to a center line in a length direction of the transition passage 122 so as to place the rotating means 1 in the transition passage 122 between the two second filter bodies 4.

In some embodiments, there are multiple transition passages 122, multiple resin cavity inlets 121, and each transition passage 122 communicates with one resin cavity inlet 121. In other words, the plurality of transition passages 122 and the plurality of resin chamber inlets 121 communicate in one-to-one correspondence.

The rotating device 2 is a plurality of rotating devices, and at least one rotating device 2 is arranged in each transition passage 122. In other words, the plurality of transition passages 122 corresponds to at least the same number of turning devices 2 as the number of transition passages 122.

In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the embodiment shown in fig. 7, there are two transition passages 122 and two resin cavity inlets 121, one transition passage 122 communicating with one resin cavity inlet 121 and the other transition passage 122 communicating with the other resin cavity inlet 121. The number of the rotating devices 2 is two, one rotating device 2 is arranged in one transition passage 122, and the other rotating device 2 is arranged in the other transition passage 122. Wherein, there are two sets of second filter bodies 4 in the resin cavity 12, namely 4 second filter bodies 4.

In some embodiments, the transition passage 122 includes a first section 1221, a second section 1222, and a third section 1223 connected in series along the length direction, the width of the first section 1221 is consistent along the length direction, the width of the third section 1223 is consistent along the length direction, the width of the second section 1222 is increased and then decreased along the length direction, and the rotating device 2 is located in the second section 1222.

As shown in fig. 7, the length direction of the transition passage 122 is the up-down direction, the width direction of the transition passage 122 is the left-right direction, the transition passage 122 includes, from top to bottom, a first section 1221, a second section 1222 connected to the first section 1221, and a third section 1223 connected to the second section 1222, wherein the width of the first section 1221 is kept constant in the up-down direction, the width of the third section 1223 is kept constant in the up-down direction, the width of the second section 1222 is increased from top to bottom and then decreased, and the rotating device 2 is disposed in the second section 1222.

Thus, the water entering the second section 1222 will impart a tangential force to the impeller to more easily rotate the impeller.

In some embodiments, the width of the third segment 1223 is less than the width of the first segment 1221. In other words, the width of the third segment 1223 is smaller than the width of the first segment 1221. Since the third section 1223 is in communication with the resin chamber inlet 121, the third section 1223 is closer to the resin chamber inlet 121 than the first section 1221.

Further, by reducing the width of the third section 1223 adjacent to the resin chamber inlet 121, the impact force of the water can be increased to enhance the rotating effect of the impeller; increasing the width of the first section 1221 reduces the negative pressure generated by the first section 1221, i.e., reduces the pressure difference between the transition passage 122 and the resin chamber 12, and prolongs the service life of the water softener.
