Abstract

The utility model relates to a multiple cavity ink box. A box and a cover form a box body with six sides. One side of the box body is provided with a check valve, an ink supplying tube and an ink feeding cut which are respectively corresponding to each cavity. The corresponding side is provided with an air inlet which is communicated with the atmosphere through a devious air channel. The air inlet is connected with an air sac which is arranged inside the cavity. The cavity is arranged according to the design of shortening the length and increasing the width. Some of the cavities and ink supplying tubes are extended. The utility model increases the width of each cavity and shortens the length of each cavity, thereby relatively expanding the mourning space in limit area, greatly decreasing the mounting difficulty and increasing the quality and qualification rate of products.

Description

A kind of Multiple cavity ink box

Technical field

The utility model relates to the new construction Multiple cavity ink box that a kind of ink-jet printer is used.

Background technology

The applicant produces a kind of print cartridge of structure as shown in figure 11 at present, mainly contains and covers 20; Air bag seat 21, utricule 22, flexible fastening circle 23 are formed air bag component; The check valve assembly that valve gland 24, valve body 25, filter screen 26 constitutes is positioned at the sealing ring 27 of ink supply port in addition.The print cartridge that the certain model printer is used, adopt this structure to obtain good ink supply effect, but for Multiple cavity ink box, as Five-colour ink cartridge, by traditional method is to be divided into five black chambeies that are parallel to each other with plate in the box body, five black chambeies have identical length and identical width, also have the consumption speed of considering China ink of all kinds different and be designed to different width.No matter but whether wide, because the restriction of print cartridge overall width, the width that makes each chamber has brought difficulty to assembling, thereby has directly had influence on the qualification rate of product concerning the print cartridge that adopts air bag component and check valve assembly.

Summary of the invention

Can in Multiple cavity ink box, use for making check valve and air bag component, and assembly quality can be guaranteed, improve product percent of pass, it is to change tradition the very run-in index branch chamber mode of aspect ratio is arranged that the utility model adopts the main design philosophy of technical scheme, adopt alternating expression to divide the chamber, be intended to dwindle the length-width ratio in single chamber, the utilized space when having enlarged assembling relatively, operation convenient for assembly; Because the position of the ink supply port that cooperates with printer is fixed, the problem of ink-feed channel structure behind the staggered branch of the also necessary solution chamber.

Technical solution of the present utility model is as follows: the main parts size of whole print cartridge and monochromatic print cartridge are basic identical, there is a box and one lid to constitute to be substantially six box body, on a face, have with box body in each minute chamber check valve one to one, the ink supply pipe, ink supply port, corresponding surface is provided with and the air admission hole that communicates with atmosphere by tortuous air flue, each air admission hole and one place the air bag in the branch chamber to join, divide the chamber to adopt and shorten the interlace mode that length increases width, be divided into staggered some ranks with vertical and horizontal diaphragm, because the invariant position of ink supply port, check valve is in the bottom in each branch chamber again, therefore, to branch chamber, the ink supply pipe is designed on the outer bottom of box body away from ink supply port.

The utility model increases the width in each branch chamber by adopting above-mentioned solution, and length reduces, thereby in making limited area, has enlarged assembly space relatively, has fallen at the end assembly difficulty greatly, has improved the quality and the qualification rate of product.

Embodiment

Further specify below in conjunction with embodiment and accompanying drawing thereof, this example is a Five-colour ink cartridge, the main improvement of prior art being made because of the utility model is the version in branch chamber, for clarity of illustration, air bag component same as the prior art, check valve assembly and ink supply port sealing ring etc. have all been omitted in institute's drawings attached of embodiment.

Referring to Fig. 1, five ink supply ports 1 that cooperate with printer are positioned at greatly to being on the hexahedral face, and this example is divided into five branch chambeies by three midfeathers and a diaphragm plate, each minute the chamber be arranged as two rows, wherein front-seat three branch chambeies 2, two branch chambeies 3 of row, back.

Referring to Fig. 2, front-seat three branch chambeies are from seeing vertical ink supply pipe outer wall 4 in appearance, and two branch chambeies of back row then also have horizontal ink supply pipe outer wall 5.

Referring to Fig. 3, do not show the ink supply tube cover plate in back row's branchs chamber among Fig. 3, ink supply tube cavity 7 is to be surrounded by the wall 6 on print cartridge bottom 8, the unidirectional valve seat in branch chamber under inner chamber 7 one ends contain, the other end extend to affiliated ink supply port 1 near.

Referring to Fig. 4, can be clear that the layout layout in

branch chamber

2,3 and the unidirectional valve seat 9 in each branch chamber among Fig. 4.

Referring to Fig. 5, Fig. 5 mainly represents the structure in front-seat branch chamber 2, and its bottom surface outwards is provided with unidirectional valve seat 10, ink supply pipe 11, the ink supply port 1 that check valve is installed successively, thereby constitutes ink-feed channel.

Referring to Fig. 6, Fig. 6 mainly represents the structure in row's branch chamber, back 3, and its bottom surface outwards is provided with unidirectional valve seat 10, ink supply pipe, the ink supply port 1 that check valve is installed successively, thereby constitutes ink-feed channel.Different is, the ink supply pipe has been divided into two sections, and one section is the horizontal segment that inner chamber 7 constitutes, and another section is vertical section that inner chamber 13 constitutes, and both are communicated with by hole 12.

Referring to Fig. 7, Fig. 7 be embodiment added cover 14 and ink supply tube cover plate 15 after front view.Lid 14 and ink supply tube cover plate 15 adopt ultrasonic bonding to form integral body with box main body 16, thereby constitute each minute chamber and the ink supply pipeline that respectively prolonged.

Referring to Fig. 8, what Fig. 8 showed is to cover 14 outer surface, have at five grooves 17 of the recessed complications of cap surface and the other end and each minute five air admission holes 18 being communicated with of chamber, and respectively with each minute five pouring ink holes 19 being communicated with of chamber, every air admission hole 18 connects an air bag in minute chamber.Should the surface for the print cartridge finished product also should paste one deck air guide envelope film (omitting among Fig. 8), thereby form the plasmas channel that falls each chamber negative pressure that the end increases in the use process.

Referring to Fig. 9, Figure 10, consider that from manufacturability present embodiment is told a part with the ink supply pipe that prolongs, promptly the ink supply tube cover plate 15, and it should have good flatness with the joint face of box main body 16, with the sealing after guaranteeing to weld.
