The invention relates to a life article, in particular to a simple closestool dredging device. The simple closestool dredging device includes a threaded pipe, a hose, a pear-shaped pipe, a small-mouth curved pipe, and a rubber pipe. The device is characterized in that: the threaded pipe and the hose are connected together, the hose and the pear-shaped pipe are connected together, the pear-shaped pipe and the small-mouth curved pipe are connected together, the rubber pipe is wound outside the hose, a short pipe is embedded in the rubber pipe, and a piston is mounted at the rubber pipe mouth; the threaded pipe and the small-mouth curved pipe adopt a hard material, the hose and the pear-shaped pipe adopt an elastic material; part of calcium carbonate powder is placed inside the rubber pipe, and part of a dilute hydrochloric acid liquid is placed in the short pipe. The simple closestool dredging device provided by the invention has the advantages of: simple structure, convenient use, and obvious effect. The carbon dioxide gas generated by reaction between dilute hydrochloric acid and calcium carbonate increases the air pressure in the rubber pipe, and by combining the water pressure of an external water pipe and utilizing the siphon principle, the purpose of closestool dredging can be achieved.
