And the inner peripheral wall of the convex edge of the annular wall 21 is embedded with a second sealing ring 9, and the second sealing ring 9 prevents water entering the inner cavity of the annular wall from flowing out upwards.

When the movable body 3 is pressed downward and rotated, the protrusion 322 of the movable body 3 disengages from the limiting groove 2120 and moves along the first limiting bar 2121 in a direction away from the limiting groove 2120, and when the protrusion 322 and the limiting member 212 are in a dislocated state, under the action of the spring 7, the movable body 3 moves upward to a state that the top of the flange 323 of the movable body abuts against the bottom of the protrusion 213, and at this time, the movable body 3 is in a second state, as shown in fig. 2. In the second state of the movable body 3, the water passing port 321 and the through port 211 are disposed in a staggered manner and do not communicate with each other, and thus the sub flow passage 310 and the main flow passage 20 do not communicate with each other. When the movable body 3 is in the second state, the water outlet 321 is communicated with the water flow channel 343. In the second state of the movable body 3, in order to rotate the movable body 3 relative to the shower arm 2, an impeller 33 that rotates under the thrust of water flow is relatively fixed to the bottom of the protrusion 32, and the rotation axis of the impeller 33 extends vertically, and in the second state of the movable body 3, the impeller 33 is located at the through-hole 211 and downstream of the through-hole 211 along the flow path of the water flow. Thus, the water flowing out through the through hole 211 strikes the impeller 33 to rotate the impeller 33, and the impeller 33 and the movable body 3 are fixedly connected, so that the movable body 3 rotates together with the impeller 33. In order to further accelerate the rotation of the movable body 3, the first side wall 34a of the extension member 34 is opened with a driving hole 341 communicating with the water guide passage 340 for driving the movable body 3 to rotate, the water outlet direction of the driving hole 341 is opposite to the rotation direction of the movable body 3, and the driving hole 341 and the impeller 33 rotate the movable body 3 in the same rotation direction.

In addition, in order to further stir the water flow and generate a small vortex in the central region when the movable body 3 is in the second state, the water flow around the periphery is driven to form a water flow rotating in one direction, and the top of the extending member 34 is provided with a stirring member 35 extending upward. The toggle member 35 extends along the length direction of the extension member 34, and includes a middle plate 351 disposed at a position near the center of the top surface of the extension member 34, and a first toggle piece 352 and a second toggle piece 353 disposed at two sides of the middle plate 351, wherein the first toggle piece 352 extends upward from the top edge of the first side wall 34a, the second toggle piece 353 extends upward from the top edge of the second side wall 34b, and the middle plate 351 is in smooth transition with the first toggle piece 352 and the second toggle piece 353. The toggle member 35 in this embodiment is substantially S-shaped.

The water quantity needed by washing fruits and vegetables is large, the water quantity is over the movable body 3 when the fruits and vegetables are washed, and the water quantity is not over the movable body 3 when the bowls and the dishes are washed. The working process of the cleaning machine is as follows:

when needing to wash the bowl dish, at this moment, movable body 3 is in first state, movable body 3 is in lower position state this moment, when spray arm 2 rotates, movable body 3 rotates along with spray arm 2, because the side runner of movable body 3 is linked together with the sprue of spray arm 2, at this moment, the hole for water spraying 201 of spray arm 2 upwards spouts rivers, and the apopore 3101 of movable body 3 also upwards sprays rivers, the central zone of washing chamber also can be washd promptly, the central zone of spray arm 2 can go out water promptly, can have more efflux to wash in the short time, can shorten the time of the clean tableware of washing greatly, the cleaning performance has been promoted greatly, realize quick washing.

When the fruits and vegetables need to be cleaned, the movable body 3 is rotated to make the convex portion 322 of the movable body 3 come out of the limiting groove 2120 and move upwards under the action of the spring 7, at this time, the top of the flange 323 of the convex piece 32 is abutted against the bottom of the convex edge 213 of the annular wall 21, so that the movable body 3 is in the second state, and at this time, the movable body 3 is in a higher state (namely, the height of the movable body 3 when the fruits and vegetables are cleaned is higher than that of the movable body 3 when the dishes are cleaned). In the rotation process of the spray arm 2, when water in the main flow passage of the spray arm 2 flows in through the water guide pipe 4, the through hole 211 and the water passing hole, the water impacts the impeller on the convex part 32 so as to drive the movable body 3 to rotate (for example, clockwise rotation), which is the first drive of the movable body 3, and at the moment, the water flows into the auxiliary flow passage of the movable body through the inner cavity of the annular wall and upwards sprays water through the water outlet hole; and the other part of water flows into the water guide channel 340 of the extension piece through the water flow channel and finally flows out through the driving hole, the water flow generates a reverse acting force to further push the movable body 3 to rotate clockwise, which is the second driving of the movable body 3, the superposition of the two driving generates a more driving force, the movable body 3 can be forced to rotate faster than the spray arm 2, namely, the movable body 3 can rotate relative to the spray arm 2, and the movable body 3 is equivalent to a driving wheel. The water yield is more when washing because of fruit vegetables, it can mix rivers and produce a little swirl in central zone to dial piece 35, it all rotates towards same direction to drive the apopore spun rivers of movable body 3, and the small-size torrent of the water production that 2 efflux of cooperation spray arm and go out, then rivers when guaranteeing whole fruit vegetables washing are all carrying out effectual vortex formula torrent, compare only in the past the small-size torrent that the rivers that jet flow and go out produced on spray arm 2, the torrent that produces when making whole fruit vegetables wash is more, the effect promotes obviously, the fruit vegetables abluent will be cleaner under great torrent.
