Description

A kind of water injection type pen

Technical field

The utility model relates to a kind of water injection type pen.

Background technology

Existing pen is made up of sebific duct, the pen container of the pen cap, pen core, nib, suction pipe, storage ink; nib is installed on the pen core; the nib tail end has suction pipe in to pass in the sebific duct that pen core extends to storage ink; the sebific duct that pen container is enclosed within storage ink is connected with pen core outward; play the sebific duct of protection storage ink and the effect of being convenient to grip, the mode that adds ink is a suction-type.There is obvious deficiency in this mode: the sebific duct of storage ink is tiny, and ink storage quantity is few, and sebific duct elasticity is limited, and the suction effect is bad, and it is full to be difficult for storage, and sebific duct is subjected to the ink corrosion easy to be aging, and service life is short; Ink can pollute the place that holds a pen during suction, makes troubles to use, and the reserves of pen ink inside are not easy to observe.

The utility model content

The purpose of this utility model be provide for the deficiency that remedies prior art that a kind of ink storage quantity is big, the pen of long service life, easy to use, cleaning.

The purpose of this utility model is achieved in that the water injection type pen of being made up of the pen cap, pen core, pen container, nib is installed on the pen core, the nib tail end has in one suction pipe pass pen core to extend in the pen container, the sebific duct of cancellation storage ink, pen core is threaded with pen container, there is seal the junction, and pen container is that transparent material or sidewall are provided with transparent windows.Screw off pen container during use, keep the pen container opening upwards, in pen container, inject ink, screw pen container and get final product.

Because the utility model has substituted the container of the sebific duct of storage ink as the storage ink with pen container, volume obviously increases, increased the moisture storage capacity of pen, removed simultaneously and pushed the loaded down with trivial details of water storage sebific duct repeatedly, inject ink easily and fast, health, prolonged service life of the container of storage ink; Pen container is that transparent material or sidewall are provided with transparent windows, is convenient to observe at any time the reserves of ink.

Description of drawings
