Automatic spray of cleaning liquid by detachable, safety-promotion and environmental-protection vehicle wiper

摘要

A detachable vehicle wiper comprises a wiper frame 1, a wiper arm and a rubber strip 3 gripped by the wiper frame. The rubber strip 3 has a gripped member 31 gripped by the wiper frame 1 and a blade 32 for scraping away rainwater. The blade 32 has first through-holes 33 connected to a pipe 34. The front edge of the first through-holes 33 has a shelter plate 35 extending downward to cover the blade 32. The wiper arm has a second through-hole connected to the cleaningwater tank by a conduit. The pipe 34 is connected to the second through-hole. When the wiper is actuated, cleaning liquid is sprayed from the first through-holes 33. The shelter plate 35 blocks solar radiation and thus prolongs the wiper's lifetime.
