Suction apparatus for inkjet printing device

摘要

A suction apparatus includes a volume-variable chamber having an inlet (111) and an outlet (206) which is formed by a plurality of enclosing parts (201-203, 206) including an elastic part (202). A slider (207) applies a force to the volume-variable chamber to decrease the volume thereof and a valve (205, 206) applies a force to increase the volume thereof. When the slider decreases the volume, the valve opens the outlet to drain ink and air from the volume-variable chamber. When the valve increases the volume, the valve closes the outlet to produce a suction force. <IMAGE>
