Problems solved by technology

However, in the current design, since the air chamber is directly formed on a single plastic part, in the process of hot-melting the film, if the film fails to completely seal the air chamber due to improper operation, the entire plastic part must be scrapped; in addition, for To ensure the stability of the manufacturing process, the components after the hot-melt film must be regularly tested for destructiveness during daily production. This will also cause a large number of parts to be scrapped and increase production costs.

Embodiment Construction

[0020] see Figure 1 to Figure 3 , In a preferred embodiment of the present invention, a replaceable air chamber mechanism used in an ink supply system of an inkjet printer includes a fixer 10 and at least one movable part 20 . The holder 10 is provided with at least one receiving groove 11 for receiving the movable part 20 . In this embodiment, the number of the movable parts 20 is two, one is used to provide the air chamber for connecting the color ink cartridges (not shown in the figure), and one is used to provide the air chamber for connecting the black and white ink cartridges (not shown in the figure). ) of the air chamber. Those skilled in the art should understand that the number of the movable elements 20 can be increased or decreased as required. Correspondingly, the number of the accommodating grooves 11 can also be increased or decreased as required.

[0021] The holder 10 includes an upper wall 12 and a lower wall 13 . The upper wall 12 defines an air inlet 1...

Abstract

A replaceable air chamber mechanism used in an ink supply system of an ink-jet printer is disclosed. The replaceable air chamber mechanism comprises a fixator and a movable component. The fixator is provided with an accommodation groove. The movable component is accommodated in the accommodation groove. The movable component comprises a box body and a film. A front side of the box body is provided with an opening. The film covers and is fixed on the front side of the box body. An air chamber is formed between the box body and the film. Through using a separating design of the movable component and the fixator, when leakproofness of the air chamber is poor, the movable component can be individually replaced.

Description

technical field [0001] The invention relates to an air chamber mechanism, in particular to a replaceable air chamber mechanism used in an ink supply system of an inkjet printer. Background technique [0002] In the current commercially available inkjet printer ink supply system (Ink Delivery System), there is a design that uses an air pump to inject gas from the air pressure tube into the air bag of the ink cartridge to expand it, and then push the ink into the inkjet head. In the ink storage tank, when the printing order is issued, the ink can be sprayed onto the paper through the nozzles on the inkjet head. In the current airway design, before the gas enters the ink cartridge, it will pass through an air chamber formed by a plastic part, and the airtightness of the air chamber is combined with the plastic part by a thin film by means of heat fusion. However, in the current design, since the air chamber is directly formed on a single plastic part, in the process of hot-mel...
