Abstract

The utility model provides a leakage-proof ink filling nozzle and an ink filling bottle with the leakage-proof ink filling nozzle. The leakage-proof ink filling nozzle comprises a hollow ink filling tube; a hollow connecting seat used for connecting with an ink accommodating bottle is arranged at the rear end of the ink filling tube; the inner chamber of the ink filling tube is communicated with that of the connecting seat; both the connecting seat and the ink filling tube adopt plastic parts and are made into a whole in one step through injection molding; and the front end of the ink filling tube is sealed. In the utility model, as the connecting seat and the ink filling tube of the leakage-proof ink filling nozzle are made into a whole in one step through injection molding without such fittings as needle tubes, needle guards and the like, the cost is about 30 percent of that of the traditional ink filling nozzle, the manufacturing technology is simple, and the production efficiency is high; and the front end of the ink filling tube is sealed, and a needle guard is eliminated, so that the leakage-proof function is better, and the environment pollution caused by the leaked ink because the needle guard is knocked down in the transportation of the ink filling bottle can be avoided.

Description

Leakproof refilling mouth and ink-filling bottle

Technical field

The utility model relates to a kind of leakproof refilling mouth that is used for to the ink-jet printer cartridge filling ink, relates to the ink-filling bottle with this leakproof refilling mouth in addition.

Background technology

The built-in print cartridge of common ink-jet printer is because its volume is less, and the Rong Mo amount is limited, and number of copies is less, for the bigger client of output quantity, often needs to change print cartridge, prints the cost height.And be used for can head it off to the ink-filling bottle of print cartridge filling ink, and the print cartridge filling ink by fighting each other after doing can make the print life of print cartridge improve greatly, need not often scrap print cartridge, has realized environmental protection, has reduced the printing cost widely.

Present common on the market ink-filling bottle generally is equipped with various special accessories (as the syringe of filling usefulness, needle tubing etc.).This class ink-filling bottle uses the appearance China ink bottle that general needs are opened the dress ink, uses utensil (as syringe) earlier the calm China ink bottle of ink to be extracted out again, and then is filled in the print cartridge, and step is cumbersome, and is very inconvenient concerning the user.For adapting to the needs of various customer groups, disposable refilling product has appearred at present on the market, and its capacity is less, only is applicable to disposable refilling.As shown in Figure 1, the refilling mouth portion of this refilling product generally is made up of needle guard 1, needle tubing 2 and needle stand 3 three parts, and needle guard 1 is made by soft silica gel or rubber, and needle tubing 2 is the tubule of irony, and needle stand 3 is a moulding.Needle stand 3 can be connected in the bottleneck that holds the China ink bottle, and the front end that needle guard 1 is enclosed within needle tubing 2 plays sealing function, and in the long-distance transport handling process, needle guard 1 comes off and causes ink to spill from needle tubing 2 easily, contaminated environment.

The utility model content

First purpose of the present utility model be to provide a kind of simple in structure, production cost is low, can effectively prevent the leakproof refilling mouth of ink-filling bottle ink leak in transportation.

Second purpose of the present utility model is to provide a kind of ink-filling bottle with above-mentioned leakproof refilling mouth.

For realizing above-mentioned first purpose, the utility model provides a kind of leakproof refilling mouth, comprises the refilling pipe of hollow, and the rear end of this refilling pipe has and is used to connect a Connection Block that holds the hollow of China ink bottle, the inner chamber of refilling pipe and the intracavity inter-connection of Connection Block; Wherein, described Connection Block and refilling pipe are working of plastics, the disposable one that is injection molded into of Connection Block and refilling pipe, the front end sealing of refilling pipe.

Preferably, described refilling pipe is a conical pipe, and its rear end is greater than front end.

Further, the outer peripheral face of described refilling pipe is made up of the multistage taper seat, is connected by the transition circle conical surface between adjacent two sections taper seats.

For realizing above-mentioned second purpose, the utility model provides a kind of ink-filling bottle, comprise and hold China ink bottle and leakproof refilling mouth, this leakproof refilling mouth includes the refilling pipe of hollow, the rear end of this refilling pipe has and is used to connect a Connection Block that holds the hollow of China ink bottle, the inner chamber of refilling pipe and the intracavity inter-connection of Connection Block; Wherein, described Connection Block and refilling pipe are working of plastics, the disposable one that is injection molded into of Connection Block and refilling pipe, the front end sealing of refilling pipe.

With respect to prior art, leakproof refilling mouth of the present utility model and ink-filling bottle have the following advantages:

1, the disposable one that is injection molded into of the Connection Block of this leakproof refilling mouth and refilling pipe need not needle tubing, accessory such as needle guard, and cost has only about 30% of traditional refilling mouth, and production technology is simple, the production efficiency height.

2, needle guard has been removed in the front end of refilling pipe sealing from, has better drip-preventing function, can avoid ink-filling bottle in handling process needle guard to be bumped and cause ink to spill and contaminated environment.
