Fluid dispenser

摘要

A fluid dispenser is disclosed herein. An example of such a fluid dispenser includes a housing configured to store a quantity of fluid and an ejection assembly configured to controllably emit the fluid through a nozzle. The fluid dispenser also includes a fluid chamber configured both to supply a quantity of the fluid to the ejection assembly and to define a fluid flow path between the housing and the ejection assembly. The fluid dispenser further includes a filter positioned in the fluid flow path and configured both to conduct the fluid from the housing to the fluid chamber and to restrain particles in the fluid from entering the fluid chamber. The filter is further configured to define a bubble flow path that facilitates conduction of bubbles from the fluid chamber to the housing. Additional features of this fluid dispenser are disclosed herein, as are other examples of fluid dispensers.

1. A fluid dispenser, comprising:
a housing configured to store a quantity of fluid; an ejection assembly configured to controllably emit the fluid through a nozzle; a fluid chamber configured to supply a quantity of the fluid to the ejection assembly, and further configured to define a fluid flow path between the housing and the ejection assembly; and a filter positioned in the fluid flow path and configured both to conduct the fluid from the housing to the fluid chamber and to restrain particles in the fluid from entering the fluid chamber, and further configured to have dimensions that extend across less than the total width of the fluid flow path thereby defining an open portion in total width of the fluid flow path to define a bubble flow path in the open portion that facilitates conduction of bubbles from the fluid chamber to the housing.
