Description
Technical field
The utility model relates to a kind of porous body, in particular to writing, cosmetics, opaquing fluid, liquid glue etc. smears skill
Porous body in the direct-liquid type Painting and writing tool in art field.
Background technique
In the field of scribbling, porous material is widely used, and such as in watercolor pencil, marking pen, eyeliner, is used
Porous material is as the material for absorbing and accommodating liquid.In the prior art, most common porous material is by film coated fiber
Beam and the rolled core formed, when use, are packed into penholder and are inserted into painting writing head, and rolled core both ends are communicated with the atmosphere, to inject liquid
When air to both ends discharge, liquid to both ends spread, when being also convenient for scribbling liquid discharge.But the liquid outlet quantity of rolled core can be with
It is gradually decreased using the increase of time, in turn results in that the handwriting is blurred, and rolled core has the shortcomings that raffinate amount is big.People thus
New Painting and writing tool is being studied always to overcome the shortcomings that rolled core is as liquid storage medium.
Patent document 1 (the real public clear 56-7504 bulletin of Japan) discloses and is made with the porous material of two different porosities
For the direct-liquid type Painting and writing tool of imbibition material, wherein the second imbibition material from the receiving of the supply opening of liquid storage bottom of the tube scribble liquid and to
Writing head feed flow is applied, be connected to the gas-guide tube of liquid storage pipe through the second imbibition material and is abutted with the first imbibition material, is existed when scribbling liquid
It is conducted to the first imbibition material when superfluous in second imbibition material, the first imbibition material scribbles fluid-tight air guide after liquid hold-up increase
Pipe, to realize the purpose of automatic liquid supply.The shortcomings that patent is only when the first imbibition material is absorbed from the second imbibition material
It is enough when scribbling liquid could fluid-tight gas-guide tube, needed in imbibition material when fluid-tight to scribble liquid measure big.Furthermore it is necessary to apply writing head
Reaching the second imbibition material across the first imbibition material could work, and it is long, at high cost to apply writing head.Patent document 2
(CN1749029A) a kind of direct-liquid type Painting and writing tool is disclosed, the porous material which also uses two different porosities is made
To scribble liquid adsorbent, principle is to be drawn using axial length identical multiple communicating pipes from liquid storage bottom of the tube, through low close
Degree, which is scribbled, to be connected to high density after liquid adsorbent and scribbles liquid adsorbent, will be applied writing head rear end insertion high density and is scribbled liquid adsorbent,
Writing head length is applied to achieve the purpose that shorten.However there are several disadvantages for the patent: 1. patents are provided with multiple communicating pipes
On the circumference using pen tip as axle center, but the penholder internal diameter of many Painting and writing tools is tiny, usually less than 8mm, deducts gas circuit and painting
The occupied space of outer wall for writing liquid adsorbent, leave for low-density portion scribble liquid adsorbent space it is very limited, in this feelings
Multiple communicating pipes are inserted under condition and runs through low-density portion to scribble liquid adsorbent upper extremely difficult in manufacture, and be easy because
Ring low-density portion is broken when being inserted into multiple communicating pipes in exiguous space and causes liquid leakage；2. a communicating pipe more than runs through low-density portion
The big quantity space that low-density scribbles liquid adsorbent is occupied when scribbling liquid adsorbent, low-density scribbles the absorption of liquid adsorbent and scribbles liquid
Capacity substantially reduce, when liquid storage pipe because external environment change due to export outward scribble liquid when, Painting and writing tool be easy because of low-density
It scribbles the off-capacity of liquid adsorbent and leaks；3. the patent will apply writing head and be inserted into multiple communicating pipes in high density portion and
Are set to apply on circumference of the writing head as axle center, high density portion must have big diameter and volume, due to highly dense multiple communicating pipes
Gap in degree portion scribbled liquid blocking when could fluid-tight communicating pipe, this will lead in liquid storage pipe largely scribble liquid export it is supreme
On the one hand density portion allows user to think that pouring amount is insufficient and reduces user experience, on the other hand scribbles liquid painting in liquid storage pipe
After writing, the shortcomings that high density portion functions as rolled core, traditional rolled core class Painting and writing tool, can embody；4. this painting
It writes and scribbles liquid in tool and cannot directly be conducted to pen tip from communicating pipe, and have to pass through high density portion and scribble liquid adsorbent, in liquid
The export of the needs such as body chalk, metallic ink water-color paintbrush scribbles the scribbling in application of liquid containing particle, can be because particle be scribbled by high density portion
Liquid adsorbent is filtered out and can not be scribbled.
Above-mentioned two patented technology, which is required to export more liquid of scribbling from liquid storage pipe, can be only achieved fluid-tight communicating pipe
Purpose, even if not yet scribbling, left in liquid storage pipe to scribble liquid measure less, user can take for scribbling liquid to be filled less, or
When can't see in liquid storage pipe scribble liquid when, much scribble liquid although scribbling in liquid adsorbent and still having, user will mistakenly believe that
It scribbles liquid to have run out, both of which leads to poor user experience.
