Definitions

  • the present invention relates to a universal printer cartridge.
  • the specification of the Chinese Patent Application No. 03102633.8 discloses a negative structure of a valve and a spring valve in an ink cartridge as disclosed in the method of "ink cartridge and method for regulating liquid flow”.
  • Pressure generating mechanism The negative pressure generating mechanism is placed between the ink storage area and the ink supply port.
  • the diaphragm is pressed against the valve seat by the biasing force of the spring to close the ink passage.
  • the negative pressure on the ink supply port exceeds a predetermined value due to the discharge of ink from the recording head, the diaphragm is biased against the spring loading force to leave the valve seat, and the ink passage is temporarily opened. Therefore, the ink flows from the ink storage region to the ink supply port, and the ink supply port One side of the negative pressure returns below the specified value.
  • the ink storage area is connected to the outside air, which requires an increase in the ink leakage preventing mechanism.
  • an object of the present invention is to provide a general-purpose printer ink cartridge which can stably supply ink to a recording head with a simple valve structure.
  • the liquid accommodating chamber is in a negative pressure state using an air pressure difference adjusting valve, and includes a liquid accommodating chamber and an air pressure difference connected to the liquid accommodating chamber and in a negative pressure state.
  • Regulating valve is composed of a valve member made of an elastic material and a valve housing that fits the valve member.
  • the valve member is a circular valve membrane with a small round hole in the middle, air pressure difference regulating valve
  • the utility model comprises a front valve body or an ink storage chamber, a valve member, a rear valve body or a dome, a vent hole and an air groove, an air groove is formed in the rear valve body, and a convex boss is arranged in a middle portion of the bottom surface of the groove, the valve component
  • the upper opening has a small circular hole with a flange which is pressed by the boss of the rear valve body.
  • the air pressure difference adjusting valve is disposed in the ink storage chamber or on the surface cover, and the surface cover or the ink storage chamber has a vent hole and communicates with the atmosphere.
  • the air differential pressure regulating valve of the present invention controls the overall negative pressure of the corresponding gas and liquid in the ink storage chamber.
  • the air pressure difference regulating valve is a one-way valve, which can prevent ink from leaking out from the ink storage chamber, thereby eliminating the ink leakage preventing mechanism, thereby further reducing the use cost.
  • FIG. 1 is a schematic view showing a relationship of installation position of an air pressure difference regulating valve according to the present invention
  • FIG. 2 is a schematic structural view of an air pressure difference regulating valve selected by the present invention
  • the present invention includes a liquid accommodating chamber and an air pressure difference adjusting valve
  • the air pressure difference adjusting valve includes a front valve body (or an ink storage chamber). 1.
  • a rear valve body (or a dome).
  • the air hole 2, the air tank 3, the pressure adjusting mechanism are disposed in the ink storage chamber or the surface cover, and the rear valve body 6 is provided with an air groove 3, and a central portion of the bottom surface of the groove is provided with a convex boss, and the valve film 5 is opened.
  • the air pressure difference regulating valve is installed on the ink storage chamber or the surface cover, and the surface cover or the ink storage chamber has a ventilation hole 2 Pass with the atmosphere.
