Mist collection device, liquid ejecting apparatus, and method for controlling mist collection device

摘要

A mist collection device capable of suctioning and recovering mist generated at the time of ejecting a liquid is disclosed. The mist collection device includes an exhaust duct having a suction portion which is installed to extend downwardly to suction external air. The suction portion is provided with a suction port extending in a vertical direction, and an upper end portion, which communicates with the exhaust duct, of the suction portion is installed to protrude in an annular shape from an inner bottom portion of the exhaust duct.

主权项

1. A line head type printer having a plurality of line heads, the printer comprising:
a first line head; a first mist collection device dedicated to suctioning and recovering mist generated at the time of ejecting a liquid from the first line head, the first mist collection device is disposed at a downstream side of the first line head in a transport direction of a medium; a second line head which is disposed at a downstream of the first mist collection device in a transport direction of the medium; and a second mist collection device dedicated to suctioning and recovering mist generated at the time of ejecting a liquid from the second line head, the second mist collection device is disposed at a downstream side of the second line head in the transport direction of the medium, wherein the first mist collection device and the second mist collection device each include an exhaust duct and a suction portion which has a suction port, wherein the mist is recovered to the inside of the exhaust duct through the suction port, a one end portion of the suction portion extends through a hole formed in a bottom portion of the exhaust duct, the suction portion inside the exhaust duct blocks an outflow of liquid from inside of the exhaust duct back through the suction port to the outside of the exhaust duct, the one end portion extending beyond an inner bottom portion of the exhaust duct in a direction of suction opposite to a direction of ejecting the liquid.
