Closestool dredger
The invention relates to a closestool dredger, relating to a closestool dredger and aiming at solving the problem that the dredging capacity is greatly reduced because a bowl-shaped rubber head of the traditional plunger loses most of vacuum suction effect by being easily deformed and upwards overturned when stressed in work. According to the scheme I, a rubber connecting head (2-2) is fixedly injected on the central position of the upper end of a circular rubber slab (2-1), and a handle (1) is vertically inserted into the rubber connecting head (2-2). According to the scheme II, the rubber connecting head (2-2) is fixedly injected on the central position of the upper end of the circular rubber slab (2-1), the handle (1) is vertically inserted into the rubber connecting head (2-2), and a plurality of reinforcing ribs (3) are uniformly distributed on the circular rubber slab (2-1) and the rubber connecting head (2-2) annularly. The closestool dredger disclosed by the invention is used for dredging a closestool.
