Problems solved by technology

The structural sensing part and indicating part designed in this document will cling to the wall of the ink cartridge due to the effect of magnetic attraction, causing the indicating part to fail to drop normally with the drop of ink volume
And even if the indicator and sensor can drop with the drop of the ink volume, the sensor outside the ink cartridge will also move up and down in real time, displaying the capacity status of the ink at every moment, which makes it difficult for the printer to normally read the ink capacity , requires a complex electronic judgment structure to realize, and cannot be used on existing printers, its characteristics are the same as ink cartridges that use electronic chips to control ink information, and lose ink cartridges through simple mechanical structures to achieve ink capacity "yes" and " None" reads in two states

Embodiment 1

[0014] Such as figure 1 , figure 2 As shown, the external rotary indicator ink cartridge described in this embodiment is mainly composed of a box body 1, inside the box body 1 is an accommodating chamber 2 for containing ink, and an ink supply port 3 is provided on the box body 1, and the box body 1 A fulcrum 4 is provided on the inner wall of the body 1, and a floating part 5 is hingedly connected to the fulcrum 4, and the hinge connection between the floating part 5 and the fulcrum 4 is the end point of the floating part 5, and a first induction part 6 is arranged at the end of the floating part 5 , the end of the floating member 5 is close to the side wall of the insertion direction of the box body 1, and the indication warehouse 7 is provided on the outside of the box body 1 in the insertion direction, and a point 4 is arranged in the indication warehouse 7. An indicator 8 is hinged on the fulcrum 4 of the fulcrum 8, and the end of the indicator 8 close to the box body 1...

Embodiment 2

[0017] Such as image 3 As shown, in the external rotary indicator cartridge described in this embodiment, the indicator 8 is arranged outside the box body, and the fulcrum 4 on the indicator 8 protrudes from the side wall of the box body 1 . It is provided with a pin on the fulcrum 4 to install and fix the indicator 8 . The difference between this embodiment and Embodiment 1 is that the indicator 8 is directly arranged on the outer wall of the box body 1 , and there is no indicating chamber outside the indicator 8 .

Abstract

The invention relates to an external rotary indicator ink box mainly comprising a box body, a containing cavity for containing ink is arranged in the box body, an ink supply hole is arranged on the box body, and a fulcrum is arranged on the inner wall of the box body and articulated with a floating piece; a first sensing piece is arranged at the tail end of one side wall of the floating piece close to a box body inserting direction; a fulcrum is arranged outside the box body and articulated with an indicator; a sensing piece is arranged at one end of the indicator close to the box body and corresponds to the first sensing piece; and an indicating piece is arranged at the other end of the indicator. The floating piece and the indicator in the external rotary indicator ink box can not form overgreat friction force due to the action of sensing force, can smoothly rotate around respective fulcrums and only have two ink states, i.e. a used-up state and an unused-up state, so that a computer chip of a printer can conveniently read signals. Meanwhile, the invention has reasonable structural design, convenient manufacture and little appearance limit and can be matched with various printers.

Description

technical field [0001] The invention relates to an ink box, in particular to an external rotary indicator ink box for providing printing materials for a printer. Background technique [0002] The existing ink cartridge is mainly composed of an accommodating cavity and an ink supply port. In order to display the ink capacity in the ink cartridge, a floating member with a long arm is arranged in the ink cartridge. The middle point of the floating member is hinged in the accommodating cavity, and the floating member can rotate around the fulcrum according to the amount of ink. At the same time, a transparent indicating window is arranged on the ink cartridge, and one end of the floating part is arranged in the indicating window, so that the outside world can obtain information about the use of the ink cartridge according to the position of the floating part in the indicating window. The indication window of this design communicates with the interior of the accommodating cavity...
