Definitions

  • This technical solution relates to the structural arrangement of self-acting closure of filter- ventilating unit in the input during the removal of the filter when the opening to the filter- ventilating unit is being closed.
  • the filter-ventilating units do not have any mechanisms to prevent the intrusion of dirt into the unit in the case that the filter is not placed. This may endanger the health of the user of filter- ventilating unit due to inhalation of particulates, which came into the unit at the time of the removed filter.
  • the input opening of the filter-ventilating unit is equipped with a closing mechanism that closes the opening in the moment when the unit is not equipped with a filter or in the moment when the filter is removed from the drive.
  • a closing mechanism that closes the opening in the moment when the unit is not equipped with a filter or in the moment when the filter is removed from the drive.
  • the filter pushes the closing mechanism away and thus the closing mechanism is open and the input opening of the filter-ventilating unit is released, what will allow the subsequent flow of filtered air into the drive.
  • a filter has a special extension on a junction with the filter- ventilating unit, which allows opening of a unit.
  • FIG. 1 shows the cross-section of the filter-ventilating unit with a closing mechanism without the fixed filter
  • Fig. 2 shows the cross-section of the filter-ventilating unit with fixed filter and with open closing mechanism.
  • the mouth 2 of the filter-ventilating unit is equipped in place of the filter connection 4 by closing mechanism 1, which closes the mouth 2 of filter-ventilating unit in case that the filter 4 is not connected.
  • closing mechanism 1 closes the mouth 2 of filter-ventilating unit in case that the filter 4 is not connected.
  • the closing mechanism 1 is open by the filter 4 connected to the mouth 2 of the filter- ventilating unit to enable the filtered air flow into the unit.
  • a seal 3 is placed between the closing mechanism i and the mouth of the filter- ventilating unit 2.
