Abstract

The utility model relates to an ink refill, which comprises a pen tube, a pen head and pen ink, wherein, the pen head is arranged at the lower part of the pen tube; the pen ink is arranged in the pen tube; a guide slot is formed on the pen tube; a piston is arranged in the pen tube; and the piston which is provided with a piston jack is matched with the guide slot. The ink refill has the advantages that firstly, when the ink of a pen is in short supply, the air in the pen can be compressed through the piston to squeeze the ink to the pen head, therefore, the pen ink can write smoothly; and secondly, the structure is simple, and the manufacture is convenient.

Description

Water fillable

Technical field

The utility model relates to a kind of water fillable, and particularly a kind of water fillable that is provided with piston belongs to the manufacturing scope of water fillable.

Background technology

In writing process, used water-color paintbrush usually can not write word because of ink stops up, and has damaged many water-color paintbrushes.Entangle its reason and mainly contain two aspects: the one, when fountain pen was brought into use at every turn, the phenomenon that fluid can't water conservancy diversion often appearred occurring when the nib drying causes writing; The 2nd, when fountain pen uses to a certain degree, the interior ink of barrel is reduced gradually owing to the nib ink constantly consumes, cause to be in the partial vacuum state in the shaft of a writing brush, ink is difficult to drain into nib, the phenomenon of word occurs not write.

Summary of the invention

The utility model water fillable, technical problem to be solved are to make long-term moistening, fluent writing, the not dry water fillable of keeping of nib.

Design: to achieve these goals.1, the design of piston and piston push jack is one of feature of the utility model design.The purpose of doing like this is: the one, and be when nib occurs not write word, utilize piston action, a hydraulic pressure is gone out nib; The 2nd, when being in vacuum or partial vacuum state in the shaft of a writing brush, piston is pressed into, and makes its air pressure inside identical with external pressure.2, the design of guide runner is two of the utility model feature.The purpose of doing like this is: when piston was positioned at the guide runner upper end, a water was identical with atmosphere in the shaft of a writing brush, and a water supply is smooth; When a water was under-supply, piston moved along guide rail, and the hydraulic pressure in the shaft of a writing brush to nib, is guaranteed the nib fluent writing.

Technical scheme: water fillable, comprise the shaft of a writing brush, nib, a water, nib is positioned at shaft of a writing brush below, and a water level is in the shaft of a writing brush, and the shaft of a writing brush is provided with guide groove, and piston is positioned at the shaft of a writing brush, and piston is provided with the piston push jack and mates with guide groove.

The utility model is compared with background technology, and the one, when a water is under-supply,, a water is extruded onto nib by air in the piston compression shaft of a writing brush, guarantee a water fluent writing; The 2nd, simple in structure, easily manufactured.

Fig. 2 is the main TV structure schematic diagram of the amplification of piston.

Fig. 3 is that piston arrives amplification plan structure schematic diagram.

The specific embodiment

Embodiment 1: with reference to Fig. 1～3.A kind of water fillable, comprise the shaft of a writing brush 1, nib 5, a water 4, nib 5 is positioned at the shaft of a writing brush 1 below, water 4 is positioned at the shaft of a writing brush 1, piston 3 be provided with piston push jack 6 and with guide groove 2 couplings, that is to say, the shaft of a writing brush 1 upper end is provided with guide groove 2, piston 3 is provided with piston push jack 6, and piston 3 is positioned at the shaft of a writing brush 1, piston push jack 6 and guide groove 2 couplings.

Embodiment 2: with reference to Fig. 1～3.Under the normal condition, piston 3 is positioned at the shaft of a writing brush 1 upper end again.Piston 3 flows out the gap with guide groove 2 lower ends and communicates with atmosphere to keep a water, is vacuum state thereby avoid causing in the shaft of a writing brush 1.

What need understand is: though the foregoing description is to the utility model detailed text description of contrasting; but these text descriptions; it is text description to the utility model mentality of designing; rather than to the restriction of the utility model mentality of designing; any combination, increase or omission that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.

Claims

1, a kind of water fillable comprises the shaft of a writing brush, nib, a water, and nib is positioned at shaft of a writing brush below, and a water level is characterized in that in the shaft of a writing brush: the shaft of a writing brush is provided with guide groove, and piston is positioned at the shaft of a writing brush, and piston is provided with the piston push jack and mates with guide groove.
