<p>PROBLEM TO BE SOLVED: To provide a pressure type cleaning machine for pipes which cleans a clogged drain pipe surely in a short time. SOLUTION: A pressure ball 3 which compresses air by a manual air pump and others and can store a considerable amount of air is provided. The upper end of a connection lever 5 having an air passage 53 which penetrates the middle is connected to the lower end of the ball 3. A movement shaft 4 vertically penetrates the ball 3 in the middle, and the upper end is connected pivotally to a handle 2 above the ball 3. A conical cock 45 is fixed to the lower end of the shaft 4. When the cock 45 is pulled up by operating the handle 2, and a clearance is formed between the cock 45 and a conical hole 52 at the upper end of the lever 5, high pressure air in the ball 3 is passed from the clearance through the passage 53 and introduced from the through hole 62 of a closure 6 into a clogged drain pipe, and an object packed in the drain pipe is discharged by the high pressure air to clean the pipe.</p> |
