Description
Technical field
The present invention relates to a kind of ink-cases of printers, ink box chip and data processing methods.
Background technology
At present in the print cartridge to printer ink-providing, chopping mechanism is configured with, which includes lever, and the lever is in lever
Extending direction upper-part can be rotated around print cartridge supporting table is arranged on.The chopping mechanism is included in the screening of an end of lever
Light part and the float of another end of lever.When ink is housed in print cartridge, since the density ratio ink density of float is small,
Float is moved upwards by buoyancy, and float movement drives lever rotation.When there are many ink in print cartridge, lever rotation makes screening
Light device is located near the bottom of concave portion, and stops the light sent out from the luminous component of optical sensor.When in print cartridge
When ink tails off, lever rotation makes photochopper gradually to the top movements of concave portion.When the ink in print cartridge is used up, shading
Device turns to the near top of concave portion, and cannot stop the light sent out from luminous component.When optical sensor receives
The light that luminous component is sent out then detects that the ink in print cartridge has run out.
Patent CN200910105619.8 discloses a kind of print cartridge of people's invention, and light-blocking member is set to the outer of print cartridge
Portion.When ink tails off so that soft body support cap deforms upon in print cartridge, light-blocking member is subjected to displacement, and then realizes identical technology
Effect.But light-blocking member is moved when soft body support cap is not supported by its own gravity, when having, ink adheres to or other are different
When object is present in blocking parts, due to ink tension or the adsorption capacity of foreign matter, lever assembly movement is caused, which deviation occur, to be made
Quantity of ink detects mistake.
Patent CN201010155221.8 discloses another print cartridge of people's use, and one is provided in the outside of print cartridge
Pulling force generating unit, which, which generates one, can make the pulling force that movable rod piece is moved to print cartridge mount scheme.Patent
In the pulling force generating unit be one group of magnet or spring.
Above-mentioned print cartridge technical solution has the following disadvantages：When light-blocking member is inside print cartridge, due to floating for chopping mechanism
Subdivision is easily influenced by ink surface bubble, and the pressure inside the size of the quality of chopping mechanism, shape, print cartridge
Power, quality of ink etc. are all not easy to control, thus be easy to cause ink remaining amount testing result inaccuracy.When light-blocking member exists
Complicated when outside print cartridge, wherein the elasticity of software support, the pulling force of pulling force generating unit are all difficult control, it is easy to
Cause the ink amount detection mistake of print cartridge.May be without ink in more specific print cartridge, but light-blocking member is also in recessed
Partial middle-end is easy to burn out print head in this way.
