The axis of first runner 21 and the axis of second runner 22 set up in parallel, the axis left and right direction horizontal setting of first runner 21, the rivers that flow through first water inlet 31 spout the region between the axis of first runner 21 and the axis of second runner 22, specifically, rivers spout the one side that is close to second runner 22 on first runner 21, make the rivers of spouting flow out between the axis of first runner 21 and the axis of second runner 22, make rivers give first runner 21 impact force while, the gravity of rivers still gives first blade 211 and the downward power of second blade 221, be favorable to increasing the rotational speed, promote dissolving of detergent. By arranging the rear wall 1112, the water flowing backwards along with the first rotating wheel 21 is not directly thrown out of the washing powder feeding cavity 111 but falls into the washing powder feeding cavity 111, which is beneficial to promoting the dissolution of the detergent.
The water inlet structure 30 further has a second water inlet 35 for injecting water flow into the front portion of the detergent feeding cavity 111, the water flow flowing through the second water inlet 35 flushes the detergent in the detergent feeding cavity 111 backwards, and under the action of the rotating second runner 22, part of the washing water containing detergent particles is pushed forwards again. The lower end of the second rotating wheel 22 is set to rotate forwards, that is, the second rotating wheel 22 is configured to push the washing water in the washing powder feeding cavity 111 to move forwards, so as to push part of the washing water reaching the water outlet 1111 forwards again, prolong the time of the washing water in the washing powder feeding cavity 111, further promote the dissolution of the detergent, and be beneficial to improving the washing cleaning effect.

The avoidance port 1113 is arranged, so that the structure is compact; and the rotary dissolving structure 20 is arranged backwards as much as possible, which is beneficial to increasing the flowing distance of the water flow pushed forwards by the second rotating wheel 22 and prolonging the time of the washing water in the washing powder feeding cavity 111. The distance between the horizontal plane of the lower end surface of the avoidance port 1113 and the axis of the first runner 21 is smaller than the outer diameter of the first blade 211; it is advantageous to block the water flow flowing backward along with the first runner 21.
The axis of the first rotating wheel 21 is horizontally arranged, the axis of the second rotating wheel 22 is horizontally arranged, the axis of the first rotating wheel 21 is arranged left and right, and the axis of the first rotating wheel 21 and the axis of the second rotating wheel 22 are both horizontally arranged, so that the washing water in the washing powder feeding cavity 111 can be pushed to move horizontally, the washing powder feeding cavity 111 can be impacted at corners, and the detergent can be prevented from being left.
