Abstract

An anti-blockage pipeline structure includes a connection pipe and a flow controller. The connection pipe includes inflow and outflow passages and an accommodation part that is located therebetween and has upper and lower flow chambers in fluid communication with each other, first and second inlet channels and an outlet channel. The first inlet channel is in fluid communication with the inflow passage and the upper flow chamber, and has an opening size increasing from the inflow passage. The second inlet channel is in fluid communication with the inflow passage and the lower flow chamber, and has an opening size greater than that of the first inlet channel. The outlet channel is in fluid communication with the lower flow chamber and the outflow passage. The flow controller enables or interrupts fluid communications between the upper and lower flow chambers and between the second inlet channel and the lower flow chamber.
