Abstract:
1. A device for clearing pipe blockage comprising: pumping means which can compress air by pumping and has an outlet for discharging compressed air out; an inflatable balloon which is mounted at the outlet and expands by air discharged through the outlet; a one-way valve which is mounted at the outlet to supply the air compressed by the pumping means to the inflatable balloon and to stop a flow of the air in the reverse direction; and a guide member which is formed in a cylindrical shape to surround the outside of the inflatable balloon, guides the inflatable balloon expanding by the pumping means to move forward inside a pipe, and is made of a flexible material, wherein the inflatable balloon expanding by the pumping means expands to the inside of the pipe, which is blocked, to maintain an airtight state at an inlet of the pipe, so that the blocked pipe is cleared by shock pressure by movement of the pumping unit and a change in pressure by expansion of the inflatable balloon by the compressed air.
