WIPO Patent Application WO/2024/078052
Kind Code:

Abstract:
A wiper arm nozzle, a windscreen wiper, and an automobile. The wiper arm nozzle comprises: a nozzle main body; a mounting part, the interior of the mounting part being hollow, the bottom portion thereof being communicated with a water inlet of the nozzle main body, and openings being formed in the two ends of the mounting part; and a flow guide piece inserted into the mounting part, the flow guide piece being provided with a first flow channel and a second flow channel, the first flow channel forming a first water outlet at one end of the mounting part, and the second flow channel forming a second water outlet at the other end of the mounting part, wherein the first flow channel and the second flow channel are connected to self-excitation flow channels, and the first flow channel and the second flow channel are gradually widened in the directions getting close to the water outlets. By means of arranging the first water outlet and the second water outlet, configuring the two flow channels both to be widened in the directions getting close to the water outlets, and connecting the first flow channel and the second flow channel to the self-excitation flow channels, the wiper arm nozzle enables water sprayed from the two water outlets to be in a leftward-rightward-swinging fan shape, thereby achieving more uniform spraying and a lager coverage area of water flows, and a smaller un-covered region.
