Ink box of ink-jet printer, valve component and valve core

Abstract

The invention provides an ink box of an ink-jet printer, a valve component and a valve core. The valve core comprises a valve rod and a valve block, wherein the valve block is made of an elastic material and is shaped like a trumpet; the valve rod cooperates with a corresponding valve seat so as to position the valve core on the valve seat; one end of the valve rod is in fixedly sealed connection with the end with the smallest radial size of the valve block, and the other end of the valve rod points to the shrinkage direction of a trumpet opening of the valve block; the end with the biggest radial size of the valve block is arranged on the outer side along the axial direction of the fixed end of the valve rod; a bending part, protruding along the shrinkage direction of the trumpet opening of the valve block, is arranged beside the end with the biggest radial size of the valve block; the area between the end with the smallest radial size of the valve block and the end with the biggest radial size of the valve block protrudes along the axial direction of the valve rod and opposite to the shrinkage direction of the trumpet opening of the valve block, and the corresponding protrusion tail end is arranged on the outer side of the bending part along the axial direction of the valve rod and opposite to the shrinkage direction of the trumpet opening of the valve block; and the valve rod is provided with a silt-shaped notch penetrating the valve rod along the axial direction of the valve rod. For the valve component and the ink box using the valve core, the supply of the ink is more stable.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the filing date of March 24, 2006, the patent application number of 200610071376.7, and the title of "Inkjet Printer Ink Cartridge, Valve Assembly and Valve Core". technical field [0002] The present invention relates to an inkjet printer ink cartridge, a valve assembly and a valve core, especially an ink cartridge installed on an inkjet printer carriage to provide ink to a printing head or a recording head, and a valve assembly used in the ink cartridge, and applied to the inkjet printer Spool in cartridge or valve assembly. Background technique [0003] An inkjet type recording head is an essential constituent part of an inkjet printer. The recording head is set on a carriage of an inkjet printer. The ink cartridge of an inkjet printer is responsible for supplying ink to the recording head. Early ink cartridges utilized pressure-generating ink storage chamber members to ...

Problems solved by technology

However, in the actual application process, it is found that the use effect of this umbrella valve body is not satisfactory

For example, the umbrella surface of the valve body may be reversely folded. In the case of large ink pressure fluctuations, the umbrella surface will be forced to turn back along the central axis of the umbrella surface, and the folded umbrella surface will appear or lose The function of the valve, or it is prone to breakage and damage, which affects the normal use of the ink cartridge; in the case where the structure of the ink cartridge and the umbrella valve body is fixed and cannot be disassembled, the damage to the valve body may directly lead to the scrapping of the entire ink cartridge; on the other hand, this umbrella The response of the shaped valve body to the ink pressure difference in the process of controlling the opening / closing of the ink channel is relatively rigid, causing the closing / closing action of the ink channel to lag behind the ink demand of the recording head, resulting in unstable ink supply, etc.
