Abstract

According to the present invention, the consumption of the ink used in the inkjet printer among the consumables consumed is enormous due to the increase in the number of printers used at the same time in accordance with the rapid spread of computers with the entry of the silver information society. The method of containing such ink varies depending on the type of printer, but the mechanism used varies depending on the manufacturer of the printer, but the fundamental principle is the same. Therefore, the container containing the ink, that is, the cartridge is expensive and most of the discarded once used reality. The reason for this is the consumer's perception of refill, but the refilling method is easy and the quality of printing after the refill is guaranteed by the printer manufacturer.However, the refill method manufactured and supplied by the refill company is difficult and causes damage to the printer. It does not give consumers satisfaction. This problem is an inconvenient problem in that the injecting method of ink injects and seals the ink by directly drilling holes or dismantling the cartridge in order to inject the ink on the top of the cartridge.

In addition, since the process of ink injection is complicated and there is a limit to easily recognize the refill, it is easy and also the only way to prevent the quality of printing and printer damage after refilling is to inject ink into the ink cartridge through the cartridge nozzle. In addition, in order to facilitate the injection of the ink to manufacture the ink injection jig was invented a method easy and complete. This invention injects consumable ink for refill into the ink tank, and when the ink tank is seated on the dedicated jig for ink injection, the empty cartridge which is settled on the slider where the piston part of the ink tank easily pushes the piston and is discarded after use When the cartridge slider is seated on the cartridge slider, the cartridge slider will be in close contact with the injection part of the ink tank. At this time, if the mechanism of the push slider, the mechanism that pushes the ink tank, is advanced on the jig, ink is injected into the empty cartridge, and at the time of retraction, the push tension of the spring of the shaft assembled to the push slider is released. When the air is retracted and the air is injected into the cartridge by the force of pulling the piston, the air back is formed naturally in the case of the cartridge with the air back, so that the ink leakage is prevented by balancing the force between the inside and the outside of the cartridge. . This invention is an invention that can be applied to the cartridge without the air back to completely solve the problem of the current refill to prevent the waste of nature and at the same time to implement the refill of the ink easily and fast.

Description

Invention for refilling through injection nozzle of ink cartridge for printer

The present invention is an invention for recycling a cartridge of an inkjet printer. Cartridges used in conventional inkjet printers cannot be recycled by discarding the cartridges at the time when the ink is used. Therefore, waste of resources is serious because the manufacturing cost of the cartridges is considerable. Therefore, how to recycle this cartridge has been studied. The present invention improves the problem that these resources are discarded to prevent the waste of resources by recycling the resources, and also to investigate the problems of the method of refilling the method proposed by the companies in some world to refill and analyze the problem of consumer refilling This is to solve the problem of easy refilling and printing during printing and the problem of ink leakage during refilling, so that it is for effective economic activity through recycling of resources.

Conventionally, in order to refill inkjet printers, ink has been injected into the hole drilled to refill the top of the cartridge, or the customer has refilled the hole with a drill. However, this operation is quite inconvenient for the consumer to refill. In addition, refilling technology is required, and efficiency is pointed out as a problem, and after refilling, ink leaks in the air intake hole at the bottom of the cartridge (ink leak), which causes damage to the printer and causes a lot of losses. This problem is the result of not understanding the principle of ink cartridge design fundamentally. Also, it has focused on developing the ink rather than improving the core matters of the ink cartridge and refilling it in the form of imposing a leaking problem to consumers. As a technique for solving such a problem, conventionally, it was an inconvenient method of injecting a certain amount of ink into a hole for refilling the cartridge at the top of the cartridge or disassembling the cartridge to reseal the ink after sealing the cartridge. By injecting ink into the injection nozzle, it eliminates the inconvenience of drilling holes in the top of the cartridge, especially the problem of ink leaking, especially in the case of Hewlett Packard's product, because the air back is installed inside the cartridge, Refill method is used to prevent leakage of ink by injecting air. It is almost impossible to inject a certain amount of air into the air back by inserting a syringe into the hole at the top of the cartridge, causing ink leakage. Therefore, in order to solve this problem, the ink is injected through the nozzle part of the cartridge and the air back is formed through the nozzle to solve the inconvenience of the consumer and the refill is simply completed. The core technology of the invention is the design of the refill mechanism through the nozzle. When the refill mechanism is installed as shown in Fig. 1, a product with a structure without leakage occurs between the ink tank and the connection mechanism of the cartridge is required, and the mechanism of easy refilling is realized. This is a key skill.

The technical problem of the present invention is to prevent ink leakage during refilling of ink in a cartridge, and also to solve the inconvenience of consumers during refilling, so that the biggest problem is to secure a balance of forces acting inside the cartridge during refilling. The study of the method of injecting ink and injecting a constant amount of air into the air bag is a technical problem. This is because when refilling the air, it is difficult to control the amount of air in the airbag after injecting ink, and the process of refilling is complicated and technically made. Since the injection of the amount is difficult to secure the balance of force in the cartridge, as a result, ink leakage occurs, and the ink injection amount is not constant, so there is a problem in that the printing state is poor during printing. Therefore, the technical problem of the present invention is to place the injection of the ink in the nozzle of the cartridge so that the injection of the ink and the injection of air into the air bag at the same time, and the injection of air used a method of injecting air through the cartridge nozzle In addition, although the conventional refill method uses a syringe to achieve such a method, it is possible by using a jig for refill for smooth performance of the present invention.

1 is a cross-sectional side view of a product of the present invention. The present invention is largely divided into a mounting part of the ink cartridge, a mounting part of the refill ink, and a sliding mechanism for refilling to refill. First, insert the ink (assembly of 1, 2, 3) into the key groove of the Push Slider (12), and press the used empty ink cartridge into the Cartridge Slider (5) that slides on the Body (17). ), And insert the injection part of the ink (assembly of 1, 2, 3) into the ink guide (4) made of silicon assembled in the cartridge slider (5). At this time, it is automatically settled in the nozzle part center of the cartridge to inject ink, and the silicon assembled in the air vent hole (9) blocks the air vent hole to prevent the air inside the cartridge from leaking to the outside. Is done. When the ink and the empty cartridge are installed, ink is injected. Since the ink container is inserted into the Push Slider 12, the Push Slider 12 and the ink containers (assembly of 1, 2, 3) are It remains in an integrated state. Therefore, when the push slider 12 is advanced, it moves simultaneously. The operation of the push slider (12) is to move the bearing (15) in contact with the lever (13) from the left to the right axis as shown in the drawing to facilitate the movement. This push slider (12) is a body (17) and Hush Slider (12) and Slider Shaft (14) are connected for easy sliding. Spring (16) is inserted into Slider Shaft (14) for uniformity of force and ease of return when push Slider (12) is pushed forward. In this way, when the push slider 12 is advanced, the ink in the ink container is injected into the cartridge 8. When the Lever 13 is retracted after injecting the ink, air is injected into the air back inside the cartridge to maintain the balance of pressure inside and outside the cartridge to complete refilling of the ink without leaking the ink. This invention is the principle of the operation of the refill in the case of the product with the air back inside the ink cartridge, and for the product without the air back is refilled by the same principle of operation.

The effect of the present invention is that although the cartridge containing the ink used in the inkjet printer is quite expensive, most of the empty cartridge is discarded when the use of the ink is completed, causing a waste of resources. In addition, products that are currently manufactured for refilling are not able to solve the problem of leaking refilled ink by focusing on the sales of ink rather than solving the complicated and technically required problem of refilling, causing problems of expensive printers. It's happening. It is believed that this problem can be solved and the waste of resources can be reduced when using the present invention.
