The utility model relates to office appliance field, particularly a kind of pen.

(2) background technology

Pen is a kind of conventional writing implement, and it has an ink sac that can blot, and before use, first ink sac is filled to ink, but in the time blotting, meeting residual air in ink sac, must drive air out of next with pen, in the process of catching up with, ink easily flows out from nib, flows on hand, and ink flow to be on hand difficult to clean, particularly for pupil, ink of every suction, what ink can be done is everywhere, on hand, even on clothes, very unhygienic; , because pen-holder is all generally round, especially easily drop to the ground meanwhile, damage nib.

(3) summary of the invention

The utility model, in order to make up the defect of prior art, provides the pen of a kind of not easy damaged nib, health.

The utility model is achieved by the following technical solution:

A kind of pen, comprise and hold part, ink sac, stretch into suction hose and penholder in ink sac, it is characterized in that: described ink sac upper end is the long cylinder that hard material is made, ink sac by long cylinder with hold part split and be connected, in described ink sac, be provided with sealing ring, sealing ring central authorities are provided with valve inside, and described valve inside stretches in ink sac, and described suction hose stretches in valve inside.

Described penholder is tumbler shape.

Described penholder tail end is coated with soft-body.

The beneficial effects of the utility model are:

While blotting, first insert in valve inside with air tube on ink bottle, ink-filled, so just can residual air, refills to hold part and go up, and need not catch up with air outward separately again; When the penholder of two tumblers can make pen land, penholder first lands, and has so just protected nib, and nib can not damage.

(4) brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is further described.

Fig. 1 is cross-sectional view of the present utility model.

In figure, 1 holds part, 2 ink sacs, 3 suction hoses, 4 long cylinders, 5 sealing rings, 6 valve insides, 7 penholders, 8 soft-bodies.

(5) detailed description of the invention

Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, this kind of pen, comprises and holds part 1, ink sac 2, stretches into suction hose 3 and penholder 7 in ink sac 2, and wherein the upper end of ink sac 2 is the long cylinder 4 that hard material is made, ink sac 2 by long cylinder 4 with hold part 1 split and be connected, such as clamping, be threaded etc., be provided with sealing ring 5 in ink sac 2, sealing ring 5 is connected with long cylinder 7, at sealing ring, 5 central authorities connect a valve inside 6, be equivalent to a check valve, valve inside 6 stretches in ink sac 2, and suction hose 3 stretches in valve inside 6; The whole profile of penholder 7 is tumbler shape, and weight is equipped with in its bottom, can ensure that like this when pen lands, the bottom of penholder 7 first lands, and can not damage nib; Break penholder 7 in order to prevent that pen from falling on the ground when upper, be coated with soft-body 8 at the tail end of penholder 7.

When use, use the ink bottle with air tube to fill ink in ink sac 2, then ink sac 2 is installed to and is held in part 1, now suction hose 3 enters ink sac 2 inside through after valve inside 6, at this moment just can use pen.
