Abstract

The corrugated hose comprises a corrugated pipe body, the corrugated pipe body comprises an inner pipe and an outer pipe, a forking part is arranged at the upper end of the inner pipe, the lower end of the inner pipe is a water outlet end, a reducing sleeve is arranged at the upper end of the outer pipe, the forking part can be inserted into the reducing sleeve, a connector is arranged on the forking part, and the forking part is connected with the reducing sleeve through the connector; one side of the bifurcated part is a water inlet end, the other side of the bifurcated part is provided with a plug, a water pressure sensor is arranged in the plug, and the water pressure sensor is electrically connected with an indicator lamp. According to the corrugated pipe, the forked part is arranged on the inner pipe of the corrugated pipe body, meanwhile, the reducing sleeve is arranged at the corresponding position of the outer pipe, the reducing sleeve can fix the inner pipe, meanwhile, when the corrugated pipe body is blocked, the plug is taken down for cleaning, and daily maintenance is facilitated; and the water pressure sensor is arranged in the plug and electrically connected with the indicator lamp, so that a user can be prompted to clean in time through the indicator lamp when scale in the pipeline is blocked to a certain extent, and the use is convenient.
