[0002] As living standards improve, people's demands for a higher quality of life are becoming increasingly stringent, leading to higher expectations for the quality, performance, user-friendly use, and intelligent operation of daily necessities. Dishwashers, as a convenient daily necessity, have also become part of people's lives. In principle, a dishwasher is a device that uses a nozzle to spray high-pressure water to clean dishes. A dishwasher generally includes a dishwasher inner tank, which forms a washing chamber. A dishware insertion opening is located at the front of the inner tank, where a door is positioned. Inside the washing chamber, a dishware rack and a spray device are located. To achieve an ideal cleaning effect, existing dishwasher spray devices typically comprise rotatable spray arms rotatably connected to the inner tank body. The spray arms are connected to a water channel, through which water is sprayed to clean the dishes placed in the inner tank. However, because existing spray arms are located at the bottom of the dishwasher, wastewater after being sprayed and washed can fall into the spray arm, contaminating the clean water inside the spray arm and affecting subsequent cleaning. Therefore, there is an urgent need for a dishwasher spray arm that addresses these issues. Utility Model Content

[0003] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a spray arm for a dishwasher.

[0004] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0005] A spray arm of a dishwasher comprises a spray arm body, wherein a water storage chamber is provided in the spray arm body, a plurality of spray holes are provided on the top of the spray arm body, the plurality of spray holes are evenly arranged on the spray arm body, wherein the spacing between two adjacent spray holes is equal, a spray mechanism is installed in the spray hole, a water inlet is provided at the bottom of the spray arm body, a water inlet pipe seat is installed at the bottom of the water inlet, and an aeration assembly is also installed on both sides of the bottom of the spray arm body, and the output end of the aeration assembly is connected to the water storage chamber.

[0006] It is further defined that the spray arm body includes an upper arm plate and a lower arm plate, and the upper arm plate and the lower arm plate are sealed together. Such a structural design facilitates disassembly and maintenance.

[0007] It is further defined that the spray mechanism includes a spray column installed in the spray hole, the inner side of the spray column is provided with a communication port, the inner side of the top of the spray column is provided with a limit mounting groove, the limit mounting ring is installed in the limit mounting groove, and the limit mounting ring is installed with a sealing soft rubber arranged in an X-shaped structure.
