Ink jet head structure

Abstract

The invention discloses an ink spraying head structure, which comprises the following parts: multiple printing chips with two opposite sides of printing chip possessing multiple welding pads, ink outlet side on two sides along welding pad plane vertically, ink flow with bulk, lateral ink flow corresponding to ink outlet side of two adjacent printing chips, wherein the lateral ink supplying flow heats ink drop; the spraying board possesses multiple holes, which correspond to drop generating group; when the spraying board connects printing chip, it generates ink drop on the ink spraying medium.

Description

technical field [0001] The invention relates to an inkjet head, especially an inkjet head with multiple printing chips. Background technique [0002] Inkjet printers have become the mainstream models of print output devices because of their advantages such as good printing quality, low printing cost, easy operation, low noise, and low price. The printing quality of inkjet printers mainly depends on the design of the ink cartridge, of which the ink The design of the inkjet head of the cartridge is particularly important. [0003] see figure 1 , which is a schematic diagram of an inkjet head known to use monochrome printing. Such as figure 1 As shown, the inkjet head 1 includes a single printing chip 11 and an orifice plate 12, wherein the two opposite sides of the printing chip 11 are provided with a plurality of welding pads 111, and the center of the printing chip 11 is provided with a plurality of pads 111 perpendicular to the two sides. The central ink supply channel 1...

Problems solved by technology

[0007] The main purpose of the present invention is to provide an inkjet head, which is suitable for an ink cartridge. It utilizes a plurality of printing chips combined on the same orifice plate to make an inkjet head, so that the two adjacent printing chips are adjacent to each other. The side ink drop generator group can share the side ink supply channel formed by the corresponding ink outlet sides of the two adjacent printing chips and the ink cartridge bearing seat, so as to reduce the overall area of ​​the inkjet head and increase the inkjet head. While avoiding increasing the size of the inkjet head while increasing the number of nozzle holes, it can solve the problems of low utilization rate per unit area of ​​the inkjet head and high production cost, and improve the resolution and print quality.
