Kind Code:
A2
Abstract:
The present invention relates to an auto-switching spraying apparatus. The auto-switching spraying apparatus of the present invention includes: a pipe body including at least one nozzle branch pipe and a backflow pipe for reversing the flow of water flowing through an upper opening into a branch area and supplying the water to the nozzle branch pipe; a pad disposed at the lower portion of the branch area; and a biasing unit elastically supported by a spring from a pipe body cover, between the pad and the pipe body cover coupled to a lower opening of the pipe body to bias the pad toward the upper opening. According to the spraying apparatus of the present invention, a flow passage for the nozzle branch pipe is automatically opened when water is supplied and automatically closed when the supply of water is halted. Therefore, water leakage through the nozzle may be prevented after the supply of water is halted.
