The rotation direction and rotation speed of the main arm 110 may be the same as or different from those of the spray arm 120; the rotational direction and rotational speed between the spray arms 120 may be the same or different. In the present invention, it is preferable that the rotation directions of the washing arm 111 and the spray arm 120 are opposite, and the opposite rotation directions between the washing arm 111 and the spray arm 120 enable the water jets emitted from the washing arm 111 and the spray arm 120 to wash the dishes from different angles, thereby rapidly washing the dirt on the dishes.

In the present invention, the washing arm 111 is substantially in the shape of a straight bar, the washing arm 111 is hollow to form a first water channel, and the first spraying hole 1111 is communicated with the first water channel. The extension arm 112 is a straight strip and is hollow to form a second water channel. The washing arm 111 and the extension arm 112 communicate to communicate the first water flow passage and the second water flow passage, whereby the washing arm 111 and the extension arm 112 together form a cross-shaped water flow passage. The intersection of the extension arm 112 and the washing arm 111 is provided with a first water inlet port 1113 with a downward opening, the first water inlet port 1113 is used for water inlet, and the first water inlet port 1113 is coaxial with the central axis L. The end of the extension arm 112 away from the first water inlet 1113 is provided with a water outlet 1121 with an upward opening, and the spray arm 120 is provided with a second water inlet 122 connected with the water outlet 1121 and communicated with the water outlet 1121.

In order to enable the spray arm 120 to be rotatably disposed at the water outlet 1121, in the present invention, the intermediate piece 140 is movably clamped at the outer periphery of the second water inlet 122 of the spray arm 120, the intermediate piece 140 is detachably disposed in the water outlet 1121, when the spray arm 120 is disposed at the water outlet 1121 through the intermediate piece 140, the spray arm 120 can rotate relative to the intermediate piece 140, and the intermediate piece 140 is fixed relative to the water outlet 1121, so that the spray arm 120 is rotatably connected to the water outlet 1121 through the intermediate piece 140. Referring to fig. 5 and 6, the intermediate member 140 includes an annular base ring 141, a plurality of hooks 142 disposed at the bottom of the base ring 141, and a latch 143 formed on the outer circumferential surface of the base ring 141. The outer side wall of the second water inlet port 122 is provided with a full ring-shaped rib 1221 for positioning the intermediate piece 140 in the axial direction of the second water inlet port 122, and the rib 1221 can prevent the intermediate piece 140 from separating from the second water inlet port 122. In the process of installing the intermediate piece 140 to the second water inlet port 122, the hook portion of the hook 142 needs to be installed in place after the elastic deformation capability of the hook 142 itself passes over the rib 1221, and thus, a clamping relationship is formed between the hook 142 and the rib 1221. The inner wall of the water outlet 1121 is formed with a screwing groove matched with the fixture block 143, and when the water outlet 1121 is installed, the middle piece 140 can be connected with the water outlet 1121 only by screwing the fixture block 143 into the screwing groove. In order to facilitate the rotation of the intermediate member 140, a handle portion 144 for a user to hold is further provided on the outer circumferential surface of the intermediate member 140. The user can conveniently screw the intermediate member 140 to the water outlet 1121 through the handle portion 144.

Considering that friction is generated between the outer sidewall of the second water inlet 122 and the inner circumferential surface of the base ring 141 when the spray arm 120 rotates relative to the intermediate member 140, in order to reduce frictional resistance, a first supporting boss 130 is annularly disposed on the outer sidewall of the second water inlet 122, referring to fig. 4 and fig. 8, the first supporting boss 130 extends along the radial direction of the second water inlet 122 and toward the intermediate member 140, and the first supporting boss 130 is intermittently annularly disposed on the outer sidewall of the second water inlet 122. Therefore, the friction between the second water inlet interface 122 and the middleware 140 can be effectively reduced, the kinetic energy loss is reduced, and the rotating stability of the spray arm 120 is improved. For the same purpose, the outer sidewall of the first water inlet port 1113 is annularly provided with a second supporting boss 131, and the structure of the second supporting boss 131 is the same as that of the first supporting boss 130.
