Definitions

  • the invention relates to a writing or drawing device with a housing, at the front end of which a writing tip is provided, the rear area of which is connected to a writing liquid storage space provided in the housing interior, which is connected to the ambient air via a capillary pressure compensation system.
  • Such writing and drawing devices are known in various forms, for example as so-called tube recorders, in which the writing tip consists of a writing tube to which ink can be supplied from an ink cartridge which is attached to the part of the housing carrying the writing tube.
  • a capillary pressure compensation chamber Via a capillary pressure compensation chamber, which is connected at one end to the ambient air and at its other end in connection with the interior of the housing containing the ink, pressure equalization is brought about, so that when ink is used, no negative pressure is established in the ink storage room , which would hinder another ink dispensing by the writing tube.
  • the pressure compensation chamber also serves to hold ink when there is overpressure in the ink storage room.
  • a writing or drawing device of the type mentioned is designed in accordance with the invention in such a way that a sensor that reacts to writing fluid is provided in the pressure compensation system, that the writing fluid storage space has a semi-permeable membrane that is permeable to air and impermeable to writing fluid is connected to a suction pump and that the sensor activates the suction pump when influenced by writing fluid.
  • the writing or drawing device contains a suction pump which is connected to the writing liquid storage space via a semi-permeable membrane, so that when the suction pump is activated, air is sucked out of the writing liquid storage space while writing liquid cannot pass through the semi-permeable membrane.
  • This suctioning off of the air results in a rapid lowering of the pressure in the writing liquid storage space, so that the excess pressure, for example caused by an increase in temperature, is reduced in a very short time and the normal operating state is restored.
  • the suction pump is controlled by a sensor that responds to an increased filling of the pressure compensation system caused by excess pressure and activates the suction pump, which then sucks air at least until the level in the pressure compensation system has decreased sufficiently that the sensor no longer being affected.
  • the semi-permeable membrane is in the form of a hose which extends into the writing liquid storage space and whose free end is closed, while the other end is connected to the suction pump.
  • a hose ensures that air can be extracted not only directly at the connection point between the suction pump and the writing liquid storage space, but also from other areas of the writing liquid storage space. This is particularly advantageous when the writing or drawing device is in a somewhat inclined position, in which, for example, writing fluid is present in the connection area between the suction pump and the writing fluid storage space.
  • the other end of the hose facing away from the free end of the hose can sit on a tubular connecting piece which extends through a wall delimiting the writing liquid storage space.
  • the writing or drawing device partially shown in section has a holder-shaped housing 1, at the front end of a detachable housing part a schematically illustrated writing tip 2, which has the shape of a writing tube, a fiber tip, a writing or drawing pen or the like. may have been arranged.
  • the inner end of the writing tip 2 is not in illustrated manner connected to the interior of the housing 1 forming the writing fluid storage space 3, in which the writing fluid 4, such as ink or ink, is located.
  • a capillary pressure compensation chamber 5 is provided in the wall of the housing 1 in a manner customary for such writing instruments, the front end of which is connected to the writing liquid storage space 3 and the rear end of which is connected to the ambient air.
  • a sensor 7 in the latter which consists, for example, of a temperature-dependent resistor, of a capacitive sensor or the like. can exist.
  • the writing fluid reservoir 3 is closed at the rear end by a transverse wall 6 through which a pipe socket 9 extends.
  • the housing 1 On the side of the transverse wall 6 facing away from the writing liquid storage space 3, the housing 1 forms a further interior space 8 in which a suction pump 11 with a drive motor 12, an electronic circuit arrangement 13 controlling the operation of the drive motor 12 and a battery 14 feeding the motor 12 are accommodated.
  • the suction pump 11 has a maximum delivery rate of 0.1 mL air / minute.
  • the circuit arrangement 13 is coupled to the sensor 7 via a line connection indicated by dashed lines and evaluates signals from the latter in the usual way.
  • a hose 10 is plugged onto the nozzle 9, which is closed at the end facing away from the nozzle 9 and which forms a semi-permeable membrane through which air can pass, but which retains liquid.
  • a tube made of polytetrafluoroethylene with a pore size of 0.2 ⁇ m to 0.45 ⁇ m is suitable as the material for this.
  • writing fluid 4 escapes into the pressure compensation chamber 5 until writing fluid in the area of the sensor 7 or comes into contact with this.
  • the sensor 7 then sends a signal to the circuit arrangement 13, which activates the motor 12 of the suction pump 11, so that the suction pump 11 sucks air out of the writing liquid storage space 3 via the connection piece 9 and the hose 10 acting as a semi-permeable membrane.
  • the sensor 7 therefore sends a signal to the circuit arrangement 13, which indicates the drop in the liquid level in the pressure compensation chamber 5, so that the operation of the suction pump 11 can be interrupted again.
