Suction-type sewer scavenger observation window
The invention discloses a suction-type sewer scavenger observation window. A suction-type sewer scavenger observation window mechanism is formed by working parts of a tank (1), a water pipe (2), a nozzle (3), a clearing valve (4) and an observation window (5). When dirt is attached to observation window glass and observation is influenced by blurring, the clearing valve (4) is opened, and clear water passes through the water pipe (2) and the nozzle (3) to flush the glass of the observation window (5), so as to recover the cleanness of the observation window (5).
