Problems solved by technology

[0005] The present invention provides a sealing ring used in an ink-jet printer ink box to solve the problem that the sealing ring used in the existing ink-jet printer ink box is prone to ink seepage at the ink outlet and the ink introduction hole of the ink supply needle when the ink supply needle is inserted and pulled out The ink is easily squeezed into the ink supply needle, which may cause technical problems of the inkjet head dripping ink

Embodiment 1

[0024] Such as figure 1 Shown is a perspective view of the sealing ring 1 involved in the present invention. The sealing ring 1 is roughly cylindrical, and at least one ring of flanges is formed on the cylindrical surface 2. In this embodiment, two rings of flanges 3 are provided to seal the outlet of the ink cartridge. Ink port; 4 is the upper end face; 5 is the lower end face.

[0025] Such as image 3 with Figure 4 Shown are a plan view and a longitudinal cross-sectional view of an ink supply needle 13. The ink supply needle 13 is a hollow needle with an ink passage 137 formed inside, and includes a needle-like tip with a tapered portion 134 gradually expanding from the front end to the base end. 133 , a cylindrical straight portion 135 connected to the needle-shaped tip 133 , and a skirt-shaped enlarged diameter portion 136 formed in a state of gradually expanding from the lower end of the straight portion 135 to its downstream side. The tapered portion 134 on the fron...

Embodiment 2

[0030]Another practicable technical solution is that for an ink supply needle that only contains a tapered portion 134 and a straight portion 135, the diameter of the lower end hole 8 on the lower end face 5 can be set to be the same as the diameter of the lower end hole 8 on the upper end face 4. The diameters of the upper hole 7 are equal, that is, the diameters of the upper hole 7 and the lower hole 8 are smaller than the diameter of the straight part 135 of the ink supply needle, and other technical features are the same as those of the first embodiment. When the ink supply needle is inserted into the ink outlet, both the upper hole 7 and the lower hole 8 can seal and fix the ink supply needle.

Embodiment 3

[0032] Another feasible technical solution is that the upper end surface 4 of the sealing ring 1 does not contain the above-mentioned recess 6, that is, the upper end surface 4 is a plane with an upper end hole 7 formed in the middle, and the sealing ring 1 is located above the upper end hole 7. If it is cut off, the overall depth of the sealing ring 1 is shortened, and the ink introduction hole of the ink supply needle will not be blocked by the upper end surface 4, and other technical features are the same as those in the first or second embodiment.

Abstract

The invention relates to a sealing ring for an ink box of an ink-jet printer. The sealing ring comprises a roughly cylindrical body, and the body comprises an upper end face close to ink in the ink box and a lower end face opposite to the upper end face. The sealing ring is characterized in that a cavity is arranged between the upper end face and the lower end face, an elastic plane is arranged in the middle of the cavity and divides the cavity into an upper cavity body close to the upper end face and a lower cavity body close to the lower end face, an upper end hole is formed in the middle of the upper end face of the sealing ring, diameter of the upper end hole is smaller than or equal to that of an ink supply needle, and a lower end hole is arranged on the lower end face of the sealing ring. The sealing ring solves the technical problems that when the ink supply needle is inserted and drawn out, an existing sealing for an ink box of the ink-jet printer is prone to ink bleed of an ink outlet, and ink at ink guide inlets of the ink supply needle is squeezed into the ink supply needle easily to possibly result in ink dropping of an ink gun.

Description

technical field [0001] The invention relates to a sealing ring used in an ink box of an ink-jet printer. Background technique [0002] At present, there are many ways for an ink cartridge to supply ink to an inkjet printer. One of the ways is to set an ink supply needle on the printer, and the tip of the ink supply needle is provided with an ink inlet hole. The ink in the ink cartridge is introduced into the printer through the ink introduction hole. A sealing ring is usually installed at the through hole of the ink outlet to prevent ink from flowing out. [0003] Wherein, a sealing ring is composed of an ink chamber section, a throat section and an introduction section, and a stopper is arranged at the throat section, and the stopper will be punctured when the ink supply needle is inserted into the ink outlet. This kind of sealing ring only has a sealing effect on the ink supply needle, and has no effect on fastening the ink supply needle. The ink supply needle may be ben...
