Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the spray arm of the present embodiment includes a body 1, a flow channel 11 extending along a length direction of the body 1 is provided in the body 1, a water inlet 12 communicated with the flow channel 11 is provided on a bottom wall of the body 1, and a water spray hole 13 is provided on a top wall of the body.

The body 1 is provided with a partition 14 which can divide the flow passage 11 into an upper flow passage 111 and a lower flow passage 112 which are independent from each other, the lower flow passage 112 is communicated with the water inlet 12, and the water spray hole 13 is communicated with the upper flow passage 111. The water spray holes 13 are disposed near both ends of the body 1 corresponding to the top of the upper flow path 111. The partition 14 is provided with a water through hole 141 for allowing water to flow from the lower flow passage 112 into the upper flow passage 111, and the diameter of the water through hole 141 is larger than that of the water spray hole 13.

Specifically, a disc-shaped water collecting cavity 15 is formed in the middle of the body 1, the water inlet 12 is correspondingly formed in the bottom of the water collecting cavity 15, the lower runner 112 is tangentially connected with the water collecting cavity 15, and a flange 16 connected with the inner top wall of the body 1 to limit the volume of the upper runner 111 is arranged on the upper wall surface of the partition plate 14. The water collecting chamber 15 and the lower flow passage 112 are configured to increase the water pressure, and the rib 16 limits the volume of the upper flow passage 111 to further increase the water pressure.

The volume of the upper flow passage 111 is 1/3 to 4/5 times of the volume of the lower flow passage 112, the number of the water through holes 141 on both sides of the water collecting cavity 15 is 4, and the diameter of the water through holes 141 is 5 to 10 times of the diameter of the water spraying holes 13.
