Description

Print cartridge

Technical field

The present invention relates to the print cartridge that a kind of ink-jet printer is used.

Background technology

As shown in Figure 1, direction X is pack into the installation direction of printer of print cartridge 100.Print cartridge 100 has housing 110, and housing 110 has roof 101, diapire 102, antetheca 103.Antetheca 103 bottoms are provided with ink outlet port 121, and top is provided with the first occlusion part 122, and the outside at middle part is provided with the second occlusion part 123.Be provided with transmittance section 124 between the second occlusion part 123 and antetheca 103, the inboard at antetheca 103 middle parts is provided with transparent area 125.Whether the first occlusion part 122 is in place for detection of print cartridge 100.The second occlusion part 123 is used for judging the type of print cartridge 100 along the thickness of direction X, as color or volume type.Float 130 in the black chamber of print cartridge 100 can 131 rotate around the shaft, and ball float 133 floats along with the ink water level in print cartridge 100 and drives float 130 to rotate.When the interior ink of print cartridge 100 is sufficient, the light barrier 132 of float 130 is positioned at the below of transparent area 125, does not block the optical signal of printer; When print cartridge 100 interior ink cartridge low, the light barrier 132 of float 130 is positioned at transparent area 125, has blocked the optical signal of printer.When printer detects optical signal and do not blocked by light barrier 132, assert the ink surplus deficiency of print cartridge 100, forbid continuing to print.

The shortcoming of above-mentioned print cartridge is complex structure, and float occupies the large quantity space in black chamber, has reduced the print cartridge ink capacity.In addition, the light transmissive material that transparent area 125 is higher by cost make and with the housing seamless link to realize the function of printing opacity and ink storage, be to guarantee light transmittance, prevent light because of scattering or refraction excessively weak, the Surface Machining required precision of transparent area is high, and difficulty of processing is large, and cost is high.

Summary of the invention

The object of the invention is to provide a kind of structure simpler, and ink capacity is higher, and housing is easy to the print cartridge of processing.

For realizing described purpose, print cartridge of the present invention comprise there is antetheca, the housing of roof and diapire, be arranged on the ink outlet port of the bottom of antetheca, be arranged on first occlusion part on the top of antetheca, be arranged on second occlusion part in the outside at the middle part of antetheca, transmittance section between the second occlusion part and antetheca, be arranged on housing and be positioned at the 3rd occlusion part of inboard at the middle part of antetheca, is arranged on the chip on the outer surface of housing.Wherein, chip comprises the memory that stores the ink balance information and the communication section for carrying out communication with the printer mainboard.

From above scheme, owing to adopting the 3rd occlusion part to replace transparent area, and set up communication by the communication interface of printer mainboard with the communication section of chip and be connected, printer can read the ink balance information of storing on the memory of chip, after printing, the new ink balance information that printer disappears deduction after ink consumption writes the memory of chip.So just, can realize that the ink surplus detects, without float is set in print cartridge, also without transparent area is set on housing, be also the print cartridge housing without using light transmissive material, each occlusion part of print cartridge and housing can be one-body molded by cheap opaque material, and the materials that reduced the print cartridge moulding require and the processing technology requirement, simplify print cartridges structure, improve the ink capacity of print cartridge, improved the flexibility of print cartridges structure design, reduce production costs.

Further scheme is that chip is arranged on roof.Can prevent the inkiness that chip is leaked like this.

Further scheme is, communication section is electric contact, is positioned at the side of chip back to print cartridge.Cost simple in structure is low.

The specific embodiment

As shown in Figure 2, direction X is pack into the installation direction of printer of print cartridge 200.Print cartridge 200 has housing 210, and housing 210 has roof 201, diapire 202, antetheca 203.The outside of antetheca 203 bottoms is provided with ink outlet port 221, and 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.Be provided with transmittance section 224 between the second occlusion part 223 and antetheca 203, the inboard at antetheca 203 middle parts is provided with the 3rd occlusion part 225.Whether the first occlusion part 222 is in place for detection of print cartridge 200.The second occlusion part 223 is used for judging the type of print cartridge 200 along the thickness of direction X, as color or volume type.When print cartridge 200 is installed in printer, the optical signal for detection of the ink surplus of printer is all blocked by the 3rd occlusion part 225 in the whole consumption process of ink.

As shown in Figure 3, chip 230 is arranged on the outer surface of housing 210 and is positioned on roof 201, and chip 230 has memory (not shown) and the electric contact 231 that stores the ink balance information.Wherein, electric contact 231 is positioned at the side of chip 230 back to print cartridge 200, as the communication section for carrying out communication with the printer mainboard.

Print cartridge 200 is packed into after printer, the communication interface of printer mainboard is set up communication with the communication section of chip 230 and is connected, printer reads the interior ink balance information of memory of chip 230, if balance information is lower than the lower threshold of setting in printer, printer prompts more renews print cartridge, if balance information higher than the lower threshold of setting in printer, allows to print.After printing, the new ink balance information that printer disappears deduction after ink consumption writes the memory of chip 230.

When communication section is electric contact, the communication interface of printer mainboard is also electric contact.But communication section of the present invention is not limited to electric contact, can also be radio-frequency coil, now the communication interface of printer mainboard is also radio-frequency coil.

The light that each occlusion part of the present invention sends the light emission part of printer " blocking " is not limited to optical signal is blocked, and can also be that the light that the mode by refraction or reflection makes the light emission part of printer send departs from original path and can not arrive corresponding light receiver.
