Description
Technical field
The present invention relates to a kind of control air pressure balance being applicable to print cartridge and the device of balance of backflowing.
Background technology
The ink-jet printer sold in the market, its consumptive material used is print cartridge, and print cartridge can be divided into band
Shower nozzle and the box body without shower nozzle, internal equipped with sponge, it is used for adsorbing ink and makes for printing when print prints
With, when user is when using this printer ink cartridge, after internal ink is finished, because internal sponge occupies print cartridge
Space, as added ink voluntarily, adds ink amount too much, exceedes the absorbability of sponge, and ink is from print cartridge
Jet hole or the outside seepage of ink outlet port, print cartridge cannot print, and adds ink amount as reduced, and inner air cannot
All getting rid of, cause printing character or pattern to cut in and out, printing effect is undesirable, can only abandon,
Not only printing with high costs, the most also surrounding enviroment are produced severe contamination, residual ink is to water resource
Pollution extremely serious, plastic casing on the impact of soil it is also obvious that need to degrade for a long time,
Do not meet the whole world, environmental protection, low-carbon (LC), energy-conservation requirement.
In prior art, there is the print cartridge that can regulate ink storage chamber pressure, use spring, piston etc. more
Structure is as a part for air-pressure balancing device, and the structure of whole air-pressure balancing device is complex, long
During phase use, this effect of air pressure balance can be impacted, such as patent by spring failure:
CN00100899.4；The prior aries such as CN02803630.1.
It addition, in prior art, by rare for separate to print cartridge and pressure equaliser structure, this Shen
Please devise a kind of easy accessibility, it is possible to be arranged on ink box cover top, the pressure of ink box cover inner surface bottom
Thrust balancing device, and this pressure equaliser simple in construction, merely with this body structure of flexible member
Sealing and morphotropism construction features, it becomes possible to reach pressure balanced technology effect in good print cartridge
Really.
Additionally, the present invention is additionally provided with the bascule that backflows, the Main Function of the bascule that backflows has been
The device of kind this print cartridge, for when outside air temperature changes, owing to print cartridge is to seal, ink
Expanding with heat and contract with cold, air pressure in ink cartridge raises, and now, is provided with recirculation device and prevents ink from ink cartridge nozzle
Or ink outlet port overflows.
Summary of the invention
It is an object of the invention to overcome prior art not enough, it is an object of the invention to provide a kind of
Be applicable to print cartridge controls air pressure balance and the device of balance of backflowing, and this device is used primarily in device in spray
On ink ink-cases of printers, it is possible to be arranged on ink box cover top, ink box cover inner surface bottom as required,
For controlling air pressure balance and balance of backflowing, and this apparatus structure is simple, merely with the basis of flexible member
The sealing of body structure and morphotropism construction features, it becomes possible to reach pressure balance in good print cartridge,
Control the technique effect backflowed；Realize print cartridge internal without sponge, but air pressure keeps stable, can be the most anti-
Multiple circulation adds ink, it is achieved the maximum value of this print cartridge, reduces and prints cost, reaches energy-conservation, ring
The advantage protected.
And above-mentioned technique effect passes through experiment and verified, in order to achieve the above object, the present invention

The upper surface of upper shell structure of backflowing is fixed on the inner surface of ink box cover,
Upper shell structure of backflowing and lower house inside configuration of backflowing are equipped with a through hole, and through hole is through to backflow
Upper shell structure and lower house structure of backflowing；The through hole of upper shell structure of backflowing communicates with chamber of backflowing；
And the through hole of upper shell structure of backflowing communicates with the air flow chamber of the air-pressure balancing device of ink box cover；
The whole bascule that backflows is installed on below ink box cover, is positioned at print cartridge；
Backflow balance agent structure by a circle backflow sidewall, the round platform that backflows, chamber of backflowing, backflow deformation dress
Put composition；One circle backflow sidewall will backflow round platform, air flow chamber of backflowing wrap up；Backflow lower house structure
Backflow sidewall, the space of formation formed between round platform three of backflowing of inner surface, a circle is chamber of backflowing；
The round platform that backflows is positioned at the centre position of the sidewall that backflows, and the Jiang Yiquan sidewall that backflows is divided into top and the bottom；
There is a fixing hole at round platform center of backflowing, the round platform that backflows has multiple pod apertures, round platform following table of backflowing
The outermost in face is with a circle and backflows ring-shaped step；
The deformation device that backflows is formed by bottom backflow fixing end structure and deformation of backflowing；Backflow at the deformation end
Portion and the fixing end structure that backflows are made by elastomeric material；Backflow bottom deforming and fixing termination of backflowing
Structure is integrated,
The fixing end structure that backflows is formed by with next part: one section of column that backflows, diameter are more than
Backflow the fixing upper end of backflowing of column, one section of diameter more than the fixing lower end that backflows of the column that backflows；Return
The fixing upper end of stream and the fixing lower end that the backflows pillar segment that makes to backflow just is connected in consolidating on round platform of backflowing
Determine in hole, and fixing upper end of backflowing be upper, backflow fixing lower end under；
Backflow and bottom deforming, be positioned at the top of round platform；Backflow bottom deforming and the fixing end structure that backflows
Backflow fixing lower end be connected；
Backflowing bottom deformation is a substantially disc structure, from its central point toward radial direction side bottom deformation of backflowing
Upwards, there is the circle deformable seal ring that backflows toward fixing end structure rightabout projection；
Additionally, certainly backflow, the central point bottom deformation is toward in the radial direction, at the deformable seal ring that backflows
Periphery, also has the sealing ring that backflows that a circle is protruding toward fixing end structure direction of backflowing；Backflow sealing
Point on circle is the seal point that backflows, the deformable seal circle that backflows backflow seal point and the returning of the round platform that backflows
Stream ring-shaped step offset and, when the deformable seal circle that just makes to backflow not yet produces deformation, deformation of backflowing is close
Seal realizes the sealing of pod apertures.
A kind of control air pressure balance being applicable to print cartridge the most according to claim 1 and balance of backflowing
Device, it is characterised in that: upper shell structure, air pressure balance agent structure, lower house structure are in due order
Welded together by ultrasonic bonding, and the welding between three leaves no gaps；The upper shell that backflows is tied
Structure, balance of backflowing agent structure, lower house structure of backflowing are welded together by ultrasonic bonding in due order,
And the welding between three leaves no gaps.
A kind of control air pressure balance being applicable to print cartridge the most according to claim 2 and balance of backflowing
Device, it is characterised in that: in the range of gas port and the quantity in hole of backflowing all can be arranged on 2-8,
Gas port is evenly arranged on round platform, and hole of backflowing is evenly arranged on round platform backflowing.
4. according to a kind of according to any one of claim 1-3 be applicable to print cartridge control air pressure balance and
The device of balance of backflowing, it is characterised in that: omit this setting of upper shell structure of air-pressure balancing device；
Omit this setting of lower house structure of backflowing of the bascule that backflows.
