Liquid circulation device and liquid ejection apparatus

摘要

A liquid circulation device includes a supply unit that forms a flow path supplying a liquid from a reservoir unit; a collection unit that forms a flow path collecting the liquid to the reservoir unit; and N number of the connection units provided respectively corresponding to N number of ejection units ejecting the liquid forming a flow path connecting the supply unit and the collection unit via the ejection units, wherein with regard to each of N number of the connection units, a connection order of the connection units with respect to the supply unit, which is counted from upstream in a flow direction of the liquid in the supply unit coincides with a connection order of the connection units with respect to the collection unit, which is counted from upstream in the flow direction of the liquid in the collection unit.

1. A liquid circulation device, comprising:
a supply unit that forms a supply flow path supplying a liquid from a reservoir unit in a supply direction; a collection unit that forms a collection flow path collecting the liquid to the reservoir unit in a collection direction; and N number of connection units provided respectively corresponding to N number (N means a natural number of three or more) of ejection units ejecting the liquid, the connection units forming a connection flow path connecting the supply unit and the collection unit via the ejection units, each of the connection units having a supply connection point and a collection connection point, the supply connection point being a point at which each of the connection units connects the supply unit, the collection connection point being a point at which each of the connection units connects the collection unit, the connection units being arranged parallel relative to each other with respect to the supply unit and the collection unit such that the supply connection points are arranged along the supply unit from upstream to downstream of the supply direction and such that the collection connection points corresponding to the supply connection points, respectively, are arranged along the collection unit from upstream to downstream of the collection direction, with regard to each of the N number of the connection units, a connection order of the connection units with respect to the supply unit, which is counted from upstream in a flow direction of the liquid in the supply unit coinciding with a connection order of the connection units with respect to the collection unit, which is counted from upstream in the flow direction of the liquid in the collection unit.
