[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0017] Please see Figure 1-3The present application provides a multi-angle spraying dishwasher spray arm, which includes a spray arm seat 1, a main spray arm 2, a first spray arm 3 and a second spray arm 4. The main spray arm is rotatably connected to the spray arm seat, a first water outlet 5 is provided above the first end of the main spray arm 2, the first spray arm 3 is rotatably connected to the first water outlet and can rotate horizontally relative to the main spray arm 2, the first water outlet 5 is communicated with the internal water path of the first spray arm 3, after water enters the first spray arm from the main spray arm, under the pressure and impact force of the water flow, the first spray arm can rotate relative to the main spray arm; a second water outlet is provided on the side surface of the second end of the main spray arm 2, the second spray arm 4 is rotatably connected to the second water outlet and can swing relative to the main spray arm 2, the second water outlet is communicated with the internal water path of the second spray arm, after water enters the second spray arm from the main spray arm, under the pressure and impact force of the water flow, the second spray arm can rotate relative to the main spray arm, thereby indirectly increasing the spraying area of ​​the spray arm and solving the problem of spraying dead angles caused by the placement of tableware.

[0018] The spray arm seat 1 is provided with a fixed gear 6, the main spray arm is provided with a transmission part 7 and a moving gear 8, the transmission part is slidably connected to the main spray arm, the transmission part 7 is provided with an inclined groove 9 and a flat groove 10, the second spray arm 4 has a first insertion part 11 extending into the inclined groove, the moving gear 8 is rotatably connected to the main spray arm 2 and meshes with the fixed gear, the moving gear is provided with a second insertion part 12 extending into the flat groove, the second insertion part is eccentrically arranged on the moving gear, when the moving gear 8 rotates, the transmission part 7 performs a linear reciprocating motion under the cooperation of the second insertion part 12 and the flat groove 10, and the second spray arm 4 reciprocates relative to the main spray arm 2 under the cooperation of the first insertion part 11 and the inclined groove 9, specifically: when the water After the water source enters the main spray arm, the main spray arm rotates under the action of the water source pressure. When the main spray arm rotates, the movable gear is meshed with the fixed gear, so the movable gear also rotates. In the process of the second extension part arranged on the movable gear rotating from the initial position to the 180-degree position, the second extension part pushes the transmission part forward.
