Abstract
The utility model relates to an ink box of printer with a device of plunger damping and exhaust. The ink box has a small exhaust hole and a plunger hole. The ink box is connected with the plunger hole which is provided with the plungers. A piece of sealed gum paper is pasted on the small exhaust hole. When the plunger hole is arranged in the plunger, an end of the small exhaust hole near the plunger forms a cavity. The plunger appears a round column shape level II stage and surrounding the round column is provided with a plurality of small slots. When the plunger is arranged in the plunger hole, the second level stage forms a damping platform, which is to damp the ink and prevent from outflow. Before using the ink box, open the sealed gum paper of the small exhaust hole. The gas enters inner wall of the ink box through the small exhaust hole, the cavity and the slots surrounding the plunger, which enables inner ink box appearing a normal pressure state.
Description
The utility model belongs to the accessory that uses on the printer, relates in particular to a kind of ink-cases of printers that has plunger buffering exhaust apparatus.
Ink-cases of printers inside generally is vacuum state, mainly is to guarantee not having bubble in the ink, and continuous word during printing prolongs simultaneously and guarantees the quality the cycle, improves shipping mass.Print cartridge should become normal pressure with vacuum state original in the print cartridge before use, to guarantee that ink normally flows into printhead and prints, at this moment print cartridge needs exhaust, also can be described as air inlet, become normal pressure to guarantee the original vacuum state of ink, guaranteeing that ink does not leak simultaneously again overflows.
Existing print cartridge exhaust apparatus mainly adopts the labyrinth type exhaust apparatus, as shown in Figure 1, vacuumizes the preceding elder generation of can and is affixed on the ink box cover 2 with sealed adhesive paper 1, guarantees sealing.Be not communicated with steam vent 4 and maze trough 5 because vacuumize can hole 3, so do not influence exhaust when vacuumizing can.Before using print cartridge, tear the gummed paper on the maze trough exhaust pit, this moment, maze trough was still covered by gummed paper, and steam vent is communicated with maze trough, connects with normal atmosphere so print cartridge is inner, reaches the effect of exhaust or air inlet.The effect of maze trough is to guarantee that ink does not overflow.The labyrinth type exhaust apparatus is applicable to that pin type vacuumizes can, and its shortcoming is: make complexity, it is unreliable to seal, and the ink leakage phenomenon is arranged when exhaust or air inlet, the cost height.
The purpose of this utility model is exactly in order to solve the deficiency of above-mentioned technology, and a kind of ink-cases of printers that has plunger buffering exhaust apparatus is provided.
The ink-cases of printers that has plunger buffering exhaust apparatus, it is characterized in that exhaust hole, plunger hole are arranged on the print cartridge, exhaust hole and plunger hole connect, plunger is installed on the plunger hole, sealed adhesive paper is attached to the exhaust hole place, when in the plunger hole plunger being installed, plunger hole forms cavity near exhaust hole one end.
Plunger is the cylindrical of two stage steps, around first cylinder, second cylinder some sulculuses is arranged, and the diameter of first cylinder is suitable with the diameter of plunger hole.
First cylinder, second cylinder have 1--5 sulculus.
Exhaust hole diameter 0.1--5mm.
The first cylinder height 1--10mm.
The second cylinder height 0.1--1.5mm.
Because this structure of the present utility model, vacuumize can before, sealed adhesive paper is attached to the exhaust hole place, guarantee the exhaust hole sealing, then plunger is assembled.Before using print cartridge, take the sealed adhesive paper that is attached to the exhaust hole place off, by groove, cavity, the exhaust hole around the plunger, print cartridge is inner to connect with atmosphere (atmospheric pressure state), makes print cartridge inside be atmospheric pressure state, to guarantee that ink normally flows into printhead and prints.The utility model manufacturing is simple, and sealing is reliable, does not have the ink leakage phenomenon when exhaust or air inlet, and cost is low.
Fig. 1 is existing print cartridge labyrinth type exhaust apparatus schematic diagram;
Fig. 2 is a sealed structural representation of the present utility model;
Fig. 3 is the front view of plunger;
Fig. 4 is the vertical view of plunger.
Describe in detail below in conjunction with accompanying drawing.
The 1st, sealed adhesive paper, the 2nd, ink box cover, the 3rd, can hole, the 4th, steam vent, the 5th, maze trough; The 6th, cartridge body, the 7th, plunger, the 8th, exhaust hole, the 9th, plunger hole, the 10th, cavity, the 11st, the cartridge body inwall, the 12nd, buffer table, 13 is first cylinders, 14 is second cylinders.
The ink-cases of printers that has plunger buffering exhaust apparatus, it is characterized in that exhaust hole, plunger hole are arranged on the print cartridge, exhaust hole and plunger hole connect, plunger is installed on the plunger hole, sealed adhesive paper is attached to the exhaust hole place, when in the plunger hole plunger being installed, plunger hole forms cavity near exhaust hole one end.
Plunger is the cylindrical of two stage steps, around first cylinder, second cylinder some sulculuses is arranged, and the diameter of first cylinder is suitable with the diameter of plunger hole, and the diameter of second cylinder is greater than the diameter of plunger hole.
First cylinder, second cylinder have 1-5 sulculus, exhaust hole diameter 0.1--5mm, the first cylinder height 1--10mm, the second cylinder height 0.1--1.5mm.
The effect of the groove around the plunger is to guarantee that gas can pass through, and ink can not pass through, thereby guarantees that ink does not overflow.Plunger is the cylindrical of two stage steps, and the diameter of first cylinder is suitable with the diameter of plunger hole, and the diameter of second cylinder is greater than the diameter of plunger hole, when being assemblied in plunger in the plunger hole, second level step forms buffer table, and its effect is the buffering ink, does not allow it go out.
Before using print cartridge, take the sealed adhesive paper that is attached to the exhaust hole place off, at this moment, gas enters the cartridge body inwall by the groove around exhaust hole, cavity, the plunger, makes print cartridge inside be atmospheric pressure state.
