Abstract

The utility model relates to a direct liquid-type bosh filter comprising a hollow tube with two ends communicated with each other; the top of the hollow tube is provided with a soft seal block; the seal block is connected with a guide tube which is communicated with the hollow tube and the ink storing room; and an ink absorption part is arranged below the seal block and on the guide tube. Wherein, the guide tube and the ink storing part are better to adopt a tube with small holes and a sponge respectively. The utility model has a simple structure and can guarantee good water coming performance and leakage-resistance of the pen point, and can achieve the technique proposal of fast assembly with the pen and concordant shape.

Description

The aqueous pen in direct liquid type filter

Technical field

The utility model relates to a kind of aqueous pen in direct liquid type filter.

Background technology

Common direct-fluid-supply writing by: in order to the water receiver of storage ink, be located at the nib of anterior end of pen, and the ink guiding part of being located between above-mentioned water receiver and the nib constitutes.Borrow the ink guiding part to make the interior ink feed of water receiver to nib.Its ink inside guiding part reasonable in design with otherwise the direct quality of an influence tool, produce class such as nib water outlet not freely, the phenomenon stopping up and leak.The gas storage of Chinese patent 00249731 disclosed a kind of free ink pen, water storage automatic control device, its structure are that gas container lid and water receiver cover and have centre bore, and gas container covers and water receiver covers at the end and has aperture; Have aperture at the bottom of gas container and the water receiver; Ventilative flexible material is housed in the gas container, and external application gas container lid is fixing; Ventilative flexible material is housed in the water receiver, and external application water receiver lid is fixing.Though this modulator can play the smooth and anti-effect of leaking of supplying water, defective is that structure is comparatively complicated.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of simple in structure at above-mentioned prior art present situation, can guarantee that nib has good go out water-based and anti-leakage, can realize the aqueous pen in direct liquid type filter with the quick assembling of pen, outward appearance harmony again.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this aqueous pen in direct liquid type filter, comprise the hollow tube that a two connects, the higher authorities that it is characterized in that described hollow tube are equipped with a soft sealing-plug, be penetrated with one on the sealing-plug and be communicated with the guide wire of hollow tube and ink chamber, and on the guide wire that is positioned at the sealing-plug below, be with ink occlusion body.

It is good that described guide wire and described ink occlusion body adopt microporous pipe and cavernous body respectively.

Compared with prior art, advantage of the present utility model is: have good go out water-based and anti-leakage by aqueous pen in direct liquid type filter provided by the utility model, can guarantee nib providing ink abundance, and can smooth and easy discharge; This aqueous pen in direct liquid type filtration device structure is simple, quick with the pen assembling simultaneously, profile is harmonious attractive in appearance.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

A preferred embodiment of the utility model aqueous pen in direct liquid type filter as shown in Figure 1 and Figure 2.As can be seen from the figure, this filter is made of a hollow tube 1, a sealing-plug 2, a guide wire 3 and an ink occlusion body 4, wherein:

The lower beam of hollow tube 1 double as pen, its two connects, and the higher authorities are equipped with sealing-plug 2 sealings, and following adorns nib 5.

Plastics or rubber that sealing-plug 2 usefulness are soft are made, and it is good wherein selecting non-toxic medical plastic for use.Sealing plug 2 is made the cylinder that the top and the bottom external diameter does not wait, the wherein upper boom 6 internal diameter close-fittings of upper cylinder and pen, and sealing, the internal diameter close-fitting of bottom and hollow tube 1, and sealing.

Guide wire 3 adopts the microporous pipe that is covered with micropore on the walls, and this microporous pipe runs through the perforation at sealing-plug middle part, and two stretches out in outside the sealing-plug 2, to be communicated with the ink chamber of a hollow tube 1 and a upper boom.

Ink occlusion body 4 is a cylindrical cavernous body, and the inside middle of this cavernous body axially has perforation, is enclosed within on the microporous pipe 3 of sealing-plug 2 belows, and cavernous body has good storage capacity, plays the effect that prevents that ink from leaking.

With reference to Fig. 3, shown in Figure 4, when this filter is assembled mutually with other parts of pen,, make liquid sealing between sealing-plug 2 and the upper boom inwall as long as the rear end of this filter is inserted in the upper boom 6 of the pen that ink is housed.Nib 5 is arranged on the front end of hollow tube 1, can be supplied to nib 5 in the 7 guiding hollow tubes 1 of the ink in the upper boom by microporous pipe 3 like this.When the ink in the microporous pipe is too much, then can be absorbed by cavernous body, can not ooze out outside the pen.

Claims

1, a kind of aqueous pen in direct liquid type filter, comprise the hollow tube (1) that a two connects, it is characterized in that: the higher authorities of described hollow tube (1) are equipped with a soft sealing-plug (2), be penetrated with one on the sealing-plug and be communicated with the guide wire (3) of hollow tube and ink chamber, and on the guide wire that is positioned at the sealing-plug below, be with ink occlusion body (4).

2, aqueous pen in direct liquid type filter as claimed in claim 1 is characterized in that: described guide wire (3) adopts the microporous pipe that is covered with micropore on the wall.

3, aqueous pen in direct liquid type filter as claimed in claim 1 is characterized in that: described ink occlusion body (4) adopts cavernous body.
