[detailed description of the invention]
Be described in detail below in conjunction with the detailed description of the invention of drawings and Examples to this patent.
Embodiment one:
As Fig. 1 to Fig. 7, the print cartridge in the present embodiment, comprises cover 1, end box 2, first sealing ring 3, second sealing ring 4 of upper opening, air-guiding film 5, balloon membranes 6, the first spring 7, second spring 8, sealer 9, blotting block 10, air-valve assembly 11.
Cover 1 and end box 2 in roughly elongated rectangular shape, cover 1 and the detachable connection of end box 2, usually with ultrasonic technique by cover 1 hot pressing on end box 2 opening.
End box 2 is separated into the first air bag 201, second air bag 202, ink accommodating cavity 203 and air-valve assembly accommodating cavity 204, blotting block accommodating cavity 205.End box 2 bottom interior surface is provided with annular protruding rib 206,207; Balloon membranes 6, hot pressing is in fin 206 respectively, forms the first air bag 201, second air bag 202 on 207.Balloon membranes 6, makes with resilient material.First spring 7 is located in the balloon membranes 6 of caving in, and is compressed spacing by the annular flange flange 101 on fin 206 and cover 1; Second spring 8 is located in the balloon membranes 6 of caving in, and the second spring 8 is compressed spacing by the annular flange flange 102 on fin 207 and cover 1.In order to avoid the end that the first spring 7 and the second spring 8 contact balloon membranes 6 punctures balloon membranes 6, cave in towards the other end in this end.
The shorter side of end box 2 is provided with ink hole 208, gas hole 209 and fill with ink hole 210, and gas hole 209 is located at ink hole 208 and is filled with between ink hole 210.Gas hole 209 and the first air bag 201 are by first passage 211, and second channel 212 is communicated with, and the first air bag 201 is communicated with by third channel 213 with the second air bag 202, first passage 211, second channel 212, and third channel 213 is positioned at bottom end box 2; Ink hole 208, fills with ink hole 210 and is all communicated with ink accommodating cavity 203, and the first sealing ring 3, second sealing ring 4 is located at ink hole 208 respectively and is filled with in ink hole 210, realizes the sealing to ink accommodating cavity 203.
To cave in air outlet valve assembly accommodating cavity 204 and blotting block accommodating cavity 205 near the end box outer surfac of this shorter lateral sides, be provided with compared with long side the gas port 214 be communicated with blotting block accommodating cavity 205 near this shorter lateral sides.Air-valve assembly 11 comprises the 3rd spring 1101, valve block 1102, valve gap 1103.Air-valve assembly accommodating cavity 204 is provided with the 3rd spring 1101 from inside to outside successively, valve block 1102, valve gap 1103; The hole 2041 be communicated with ink accommodating cavity 203 is provided with bottom air-valve assembly accommodating cavity 204, central authorities are provided with the 3rd spring retention chamber 2042,3rd spring retention chamber 2042 is by fin 2043 uniform intervals of multiple arc around forming, and the 3rd spring 1101 is located in the 3rd spring retention chamber 2042.The annular protruding rib 2044 of a circle higher than fin 2043 is provided with outside 3rd spring retention chamber 2042, this fin 2044 and air-valve assembly accommodating cavity 204 inwall form the bracelet limit groove 2045 holding valve block 1102, and air-valve assembly accommodating cavity 204 edge is provided with valve gap locating slot 2046 and the back-shaped groove 2047 being communicated with blotting block accommodating cavity 205.In the form of sheets, the size of its profile and air-valve assembly accommodating cavity 204 is suitable for valve gap 1103, and edge is provided with the locating dowel 11031 suitable with locating slot 2046 size, and it is provided with intercommunicating pore 11032 in back-shaped groove 2047 position.Valve block 1102 is made up of softer and resilient material, the size of its profile and air-valve assembly accommodating cavity 204 is suitable, valve block 1102 central authorities are provided with and can insert the 3rd spring 1101 and the hollow circuit cylinder 11021 giving spring retainer, edge is provided with annular protruding rib 11022, valve block 1102 covers on the 3rd spring 1101, and annular protruding rib 11022 is located in bracelet limit groove 2045; Hole 2041, hollow circuit cylinder 11021, intercommunicating pore 11032, back-shaped groove 2047, blotting block 10, gas port 214 is by ink accommodating cavity 203 and ft connection.Blotting block 10 is located in blotting block accommodating cavity 205, and sealer 9 hot pressing is in blotting block accommodating cavity 205, and back-shaped groove 2047, on air-valve assembly accommodating cavity 204, first passage 211, second channel 212, on third channel 213.Air-guiding film 5 hot pressing is on gas port 214.
As Fig. 8 and Fig. 9, when needing to print, tear air-guiding film 5, print cartridge is loaded printer, printhead punctures the first sealing ring 3, second sealing ring 4 and gas hole 209.First time is when installing, printhead gives the first air bag 201 air feed by gas hole 209, air is through first passage 211, second channel 212 enters the first air bag 201, and balloon membranes 6 expands, then enters the second air bag 202 through third channel 213, the space of ink accommodating cavity 203 diminishes, pressure increase in print cartridge, ink is extruded and supplies printhead through ink hole 208, completes print cartridge installation cleaning function; Because pressure in print cartridge is large, valve block 1102, to deformation outside valve gap 1103 side, with its close contact, thus stops extraneous air to enter.When air feed stops, in print cartridge, pressure diminishes, and the first spring 7 and the second spring 8 are compressed under the inside pressure of cover 1, thus the first air bag 201, second air bag 202 is shunk; Valve block 1102 is away from valve gap 1103 side deformation, print cartridge outer air is through gas port 214, the hole of blotting block 10, back-shaped groove 2047, the intercommunicating pore 11032 of valve gap 1103, the hollow posts 11021 of valve block 1102, the hole 2041 that air-valve assembly accommodating cavity 204 is communicated with ink accommodating cavity 203 enters ink accommodating cavity 203, make the pressure balance inside and outside print cartridge, ink continues to flow out ink hole 208 under the effect of printhead suction force, completes ink supply.
From the above-mentioned course of work, when print cartridge first time installation or printer do not print, the pressure in print cartridge needs outside tonifying Qi very greatly and not, valve block 1102 outwards deformation, and valve gap 1103 closely sticks together, and outside air can not enter in box.Simultaneously blotting block 10 all effectively prevent ink and flows out from gas port 214, occurs dripping a black phenomenon.Blotting block 10, while leakproof, it also avoid the pollutants such as external dust and enters in print cartridge, serves good filtration.The structure of blotting block 10 and air-valve assembly 11 make air at the uniform velocity enter in box, print cartridge internal and external pressure balance control performance is stablized, thus realizes print cartridge ink supply and stablize, and printing effect is smooth.
The type print cartridge because of capacity large, length is longer, and the air blowing volume of printhead is larger when installing, length bearing of trend there is multiple air bag coordinate, atmosphere pressure energy is delivered to the other end from one end of print cartridge, first air bag 201 is connected with gas hole 209 by the passage of three bottom end box with the second air bag 202, thus make air-valve assembly accommodating cavity 204, blotting block accommodating cavity 205 and first passage 211, the sealing of second channel 212 and third channel 213 only just can realize sealing by sealer 9, only need a hot pressing process, operation is simple.
The foregoing is only the preferred embodiment of this patent, be not limited to this patent, for a person skilled in the art, this patent can have various modifications and variations.Within all spirit at this patent and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in this patent.
