Abstract
A fluid ejection device includes a fluid slot, a fluid ejection chamber communicated with the fluid slot, a drop ejecting element within the fluid ejection chamber, a fluid circulation channel communicated at one end with the fluid slot and communicated at another end with the fluid ejection chamber, a fluid circulating element within the fluid circulation channel, and a channel wall separating the fluid ejection chamber and the fluid circulation channel. The fluid circulation channel includes a channel loop, and a width of the channel wall is based on a width of the channel loop and a width of the fluid ejection chamber.
Claims20
A fluid ejection device, comprising:
- a fluid slot;
- a fluid ejection chamber communicated with the fluid slot;
- a drop ejecting element within the fluid ejection chamber;
- a fluid circulation channel communicated at one end with the fluid slot and communicated at another end with the fluid ejection chamber;
- a fluid circulating element within the fluid circulation channel;
- and
- a channel wall separating the fluid ejection chamber and the fluid circulation channel, the channel wall defined as a distance between a sidewall of the fluid ejection chamber and a sidewall of a portion of the fluid circulation channel in which the fluid circulating element is positioned,
- wherein the fluid circulation channel includes a channel loop, and
- wherein a width of the channel wall is defined based on a width of the channel loop and a width of the fluid ejection chamber.
