Printer ink supply systemTechnical field
The present invention relates to a kind of printer ink supply system of ink-jet printer.
Background technology
As shown in Fig. 1, direction X is the installation direction that printer ink supply system 100 loads printer.Printer ink-providingSystem 100 has housing 110, and housing 110 has roof 101, bottom wall 102, antetheca 103.The bottom of antetheca 103 is provided with out of inkMouth 121, top is provided with the first occlusion part 122, and the outside at middle part is provided with the second occlusion part 123.Second occlusion part 123 and antethecaTransmittance section 124 is provided between 103, the inner side at the middle part of antetheca 103 is provided with transparent area 125.First occlusion part 122 is used to detectWhether printer ink supply system 100 is installed in place.Thickness of second occlusion part 123 along direction X is used to judge printer ink-providingThe type of system 100, such as color or volume type.Float 130 in the black chamber of printer ink supply system 100 can around the shaft 131Rotate, ball float 133 drives float 130 to rotate with the ink water level float in printer ink supply system 100.Work as printingWhen ink is sufficient in machine ink feeding system 100, the light barrier 132 of float 130 is located at the lower section of transparent area 125, does not block and beatsThe optical signal of print machine；When ink cartridge low in printer ink supply system 100, the light barrier 132 of float 130 is located at transparent areaIn 125, the optical signal of printer has been blocked.When printer detects optical signal and do not blocked by light barrier 132, printer is assertThe ink surplus of ink feeding system 100 is not enough, forbids continuing to print.
The shortcoming of above-mentioned printer ink supply system is complicated, and float occupies the big quantity space in black chamber, reducesPrinter ink supply system ink capacity.In addition, transparent area 125 be made up of the higher light transmissive material of cost and with the seamless company of housingConnect to realize the function of printing opacity and ink storage, to ensure light transmittance, prevent light excessively weak because scattering or reflecting, transparent areaSurface processing accuracy requires high, and difficulty of processing is big, and cost is high.
The content of the invention
Present invention aims at providing, a kind of structure is simpler, and ink capacity is higher, and housing printer easy to process is suppliedInk system.
To realize the purpose, printer ink supply system of the invention includes the housing with antetheca, roof and bottom wall, ifThe ink outlet port in the bottom of antetheca is put, first occlusion part on the top of antetheca is arranged on, is arranged on the outside at the middle part of antethecaSecond occlusion part, the transmittance section between the second occlusion part and antetheca is arranged on housing and positioned at the interior of the middle part of antetheca3rd occlusion part of side, is arranged on the chip on the outer surface of housing.Wherein, chip depositing including the ink balance information that is stored withReservoir and the communication section for being communicated with printing mainboard.
From above scheme, due to instead of transparent area using the 3rd occlusion part, and by printing the communication of mainboardThe communication section of interface and chip sets up communication connection, and printer is the ink surplus letter stored on the memory for can be read chipBreath, after printing is finished, printer deduction the is disappeared new ink balance information after ink consumption writes the memory of chip.SoJust it can realize that ink surplus is detected, without setting float in printer ink supply system, without setting transparent area on housing,Namely printer ink supply system housing, without using light transmissive material, each occlusion part and the housing of printer ink supply system can be by honest and cleanThe opaque material of valency is integrally formed, and is reduced the materials requirement and processing technology requirement of printer ink supply system shaping, is simplifiedPrinter ink supply system structure, improves the ink capacity of printer ink supply system, improves printer ink supply system structure designFlexibility, reduce production cost.
Further scheme is that chip is arranged on roof.The inkiness that can so prevent chip to be compromised.
Further scheme is that communication section is electric contact, positioned at chip back to the side of printer ink supply system.StructureSimple cost is low.

Embodiment
As shown in Fig. 2, direction X is the installation direction that printer ink supply system 200 loads printer.Printer ink-providingSystem 200 has housing 210, and housing 210 has roof 201, bottom wall 202, antetheca 203.Antetheca 203 is set on the outside of bottomThere is ink outlet port 221, the outside on top is provided with the first occlusion part 222, and the outside at middle part is provided with the second occlusion part 223.Second blocksTransmittance section 224 is provided between portion 223 and antetheca 203, the inner side at the middle part of antetheca 203 is provided with the 3rd occlusion part 225.First hidesStopper 222 is used to detect whether printer ink supply system 200 is installed in place.Thickness of second occlusion part 223 along direction X is usedIn the type for judging printer ink supply system 200, such as color or volume type.Beaten when printer ink supply system 200 is installed toWhen in print machine, being used for of printer detects the optical signal of ink surplus in the whole consumption process of ink all by the 3rd occlusion part225 block.
As shown in Fig. 3, chip 230 is arranged on the outer surface of housing 210 and on roof 201, and chip 230 hasThere is the memory for the ink balance information that is stored with（Not shown in figure）And electric contact 231.Wherein, electric contact 231 is located at chip230, back to the side of printer ink supply system 200, are used as the communication section for being communicated with printing mainboard.
Printer ink supply system 200 loads after printer, prints the communication interface of mainboard and the communication section of chip 230Communication is set up to connect
Connect, printer reads the ink balance information in the memory of chip 230, if balance information is set less than in printerLower threshold, printer prompts more renew printer ink supply system, if lower limit threshold of the balance information higher than setting in printerValue, then allow printing.After printing is finished, printer disappears deduction the new ink balance information write-in chip after ink consumption230 memory.
When communication section is electric contact, the communication interface for printing mainboard is also electric contact.But the communication section of the present invention is not
It is limited to electric contact, can also be radio-frequency coil, the communication interface for now printing mainboard is also radio-frequency coil.
" the blocking " for the light that each occlusion part of the present invention is sent to the light emission part of printer is not limited to optical signal to hinderIt is disconnected, can also be by way of reflecting or reflecting so that the light that the light emission part of printer is sent deviate original path withoutCorresponding light receiver can be reached.
