Definitions

  • the invention relates to a device, in particular writing instrument, according to the preamble of claim 1.
  • the liquid conductor is a capillary wick
  • the distribution of the capillaries or their uniformity over the entire length in the production of the wick is difficult to adjust, so that the writing characteristics of different devices differ from each other.
  • with uniform distribution of the capillaries in particular When wicks are used with small diameters, the flow of ink limited, since all capillaries of the liquid conductor. its capillarity itself does not differ significantly from that of the air inlet capillary, to ink flow do not contribute.
  • the invention is based on the object, a generic device to the effect parezuentwickeln that it with cost-effective manufacturability and also at small diameter training a large liquid flow through the liquid conductor.
  • the capillary air inlet according to the invention not through the largest capillaries the liquid conductor is formed, but by capillary material of the Partition itself, the properties of the air intake can be largely be determined independently of those of the capillary liquid conductor, if only the predetermined relationships between the capillaries are respected. If the entire partition is made of capillary material, their Especially easy to make.
  • the claim 2 characterizes a particularly easy to manufacture embodiment, since medium capillaries in the manufacturing process of the respective materials set can be.
  • the claim 3 indicates a simple basic construction of the device.
  • Claim 4 is directed to an embodiment of the device such that as known per se, preferably designed as a wick liquid conductor passed through the partition to the liquid reservoir.
  • the embodiment according to claim 5 is simplified manufacturing technology, since the formation of a hole in the partition is not required.
  • the advantage is achieved that the production and the assembly of the two functional parts wick and memory unified each are, since both functional parts are combined into one component.
  • the device according to the invention can according to claims 7 and 8 not only as Writing instrument or applicator for other liquid media, but also as a supply device for a print head, as he, for example used in an inkjet printer.
  • a writing instrument has an overall cylindrical housing 2, the interior of which through a partition 4 in a liquid chamber 6 and a further chamber 8 is divided. At its left in FIG. 1 end that runs Housing 2 conical and ends in a cylindrical neck 10. In one Through opening of the cylindrical projection 10 is an applicator element 12 recorded, for example, by a writing tip, Malspitze or formed by a brush.
  • the partition wall 4 has a passage opening 14 which is a wick trained, capillary liquid conductor 16 is fully filled, up to the Application element 12 extends and this from the liquid chamber 6 liquid supplies.
  • a capillary memory 18 is received, for example is designed as a cylinder with a passage 20 through which the liquid conductor 16 leads.
  • the dimensioning is such that the material the liquid conductor 16 at least in partial areas directly in contact with the material of the memory 18 is.
  • the capillary memory can not mechanically within the chamber 8 be shown approaches held.
  • an air channel 22 passes through the approach 10 through.
  • the capillary memory 18 is formed such that the air on it can flow past through the chamber 8 through to the partition wall 4, the out consists of capillary material.
  • Fig. 2 shows three curves A, B and C, which show the percentage distribution of the capillaries for the liquid conductor 16 (curve A), the material of the partition wall 4th (Curve B) and the capillary memory (curve C).
  • the capillarity i. the height of rise, up to the a liquid penetrates into the respective capillary, increases.
  • the height of rise is both by sizing, i. in particular the diameter of the capillaries, given, as well as by the adhesion between the liquid and the Material.
  • Point I gives the smallest capillarity of the capillary material of the partition 4 and point II denotes the smallest capillarity of the material of the Liquid conductor 16.
  • the capillarity decreases with increasing Diameter of capillaries from.
  • the smallest Capillarity I of the partition wall 4, which forms part of the ventilation path larger is the capillarity of most of the capillary memory 18 (Curve C). Otherwise, the reservoir would become saturated with liquid. It is also important that the smallest capillarity I is smaller than the smallest capillarity the liquid conductor 16; otherwise the area of the liquid conductor would be with the smallest capillarity serve as air intake.
  • the mean capillarity of the Liquid conductor (with symmetrical distribution about the vertex of the Curve A) is greater than that of the partition (vertex of the curve B), the again greater than the mean capillarity of the capillary memory 18 (curve C). Due to not complete homogeneity of the respective material distributions arise capillarity more or less sharp.
  • the function of the writing instrument is the following:
  • the writing instrument is heated or the ambient pressure drops, so the negative pressure in the liquid chamber 6 decreases, causing the capillaries of capillary storage 18 fill with fluid as far as they are able this liquid against the decreasing negative pressure in the liquid chamber 6 absorb as a result of capillary forces.
  • the negative pressure in the liquid chamber 6 increases again so that the process comes to a standstill without that liquid emerges from the applicator element 12. Takes the temperature again from or the ambient pressure, the process is reversed; the rising one Vacuum in the liquid chamber 6 sucks the capillary liquid storage 18 empty.
  • the partition wall 4 need not be made entirely of capillary material, but can, for example, only in a passing through them Area consist of capillary material.
  • the capillaries both in the partition 4 as well as in the capillary liquid storage need not necessarily be formed in that the material as a whole is porous or capillary; she can also be formed by defined slots, which in the case of the partition 4 pass from the chamber 8 into the chamber 6 through the partition or in the case of capillary storage 18 in direct contact with the capillaries of the liquid conductor 16 are.
  • the ventilation path does not necessarily have to through the chamber 8 and the partition 4 pass. He can too by a region formed in another wall region of the chamber 6 be formed of capillary material. Even that of the liquid conductor 16 fully filled hole 14 does not necessarily have in the partition 4 be educated.
  • Fig. 3 shows an embodiment of the device with a very large volume of liquid chamber 6 and an applicator 24, as for example as the front formed with nozzles and via electrical lines 26 driven printhead is used in an inkjet printer.
  • the liquid conductor 16 leads directly into the applicator element 24. Otherwise, the function corresponds of the apparatus of Fig. 3 of Fig. 1.
  • Like reference numerals denote functionally identical Components.
  • FIG. 4 shows a further, modified embodiment of a writing instrument.
  • the same components for the above-described embodiments denoted by the same reference numerals.
  • the main difference between the embodiment of FIG. 4 and The above-described embodiments is that the partition 25 is formed without passage opening and that the liquid conductor and the capillary memory is combined to form an integral component 26 are, with its back directly to the capillary material of the partition 25 is applied and connected to the front of the applicator element 12 is.
  • the component 26 made of capillary material is in the housing 2 in such a way fitted so that it is securely applied directly to the partition 25, wherein at least one air channel 28 remains free along the outer circumference of the component 26, which may be extended in a section 30 parallel to the surface of the Partition 25 extends.
  • the capillaries of the material of the partition wall 25 and the component 26 are in With regard to the functions assumed by the said parts, those of 2 selected accordingly, that is, the partition 25 includes both capillaries, which correspond to the liquid conductor (curve A), and capillaries corresponding to the Air inlet (curve B) correspond. This is necessary because the liquid in the present embodiment more directly through the partition wall 25th must pass through into the component 26, both the function of the liquid conductor as well as the function of the temporary memory takes over.
  • the component 26 comprises capillaries according to the curve C (memory) and the Curve A (liquid conductor). It is understood that the curve C while the curve A can overlap.
  • capillaries are present, which correspond to the curve A, d. H. Capillaries with great capillarity, which form the fluid conductor.
  • the capillaries suck with great capillarity of the component 26 through the Capillaries with great capillarity of the partition 25 through full liquid and form the liquid conductor containing the applicator element 12 with the liquid reservoir combines.
  • the section 30 of the air channel 28 is adjacent to areas of Partition 25 whose smallest capillarity lies in the area of the curve B, d. H. which form the air inlet capillaries.
