Abstract:
1. A pressing means of a press-type medical nebulizer, the nebulizer having a medicament container and a medical spray generator disposed in the medicament container, the medicament container having an intake channel, the medical spray generator having a pressurized gas channel, the pressing means including: a base having a gas-delivering tube and a gas-releasing hole in communication with the gas-delivering tube, the gas-delivering tube being inserted into the pressurized gas channel for allowing the pressured gas to flow through the pressurized gas channel, a wall protruding from an outer surface of the base and further bent upward to form a trough on the side of the gas-releasing hole; a pressing element comprising an operating arm pivotally connected into the trough, a valve extending from the operating arm and positioned to correspond to the gas-releasing hole, and an elastic arm connected to the operating arm to abut against the medicament container; and a switching element being directly against the valve and slidingly provided on the operating arm to be selectively engaged into the trough for fixing the operating arm; wherein when the operating arm is in a released position, the elastic arm is relaxed and keeps the operating arm away from the base, and the wall restricts the switching element from sliding into the trough; when the operating arm is in a pressed position, the elastic arm deforms by pushing the operating arm, and the switching element is slidably engaged into the trough; wherein the switching element is allowed to slide into the trough to be directly clamped between the valve and the wall to prevent the operating arm back to the released position due to the elastic force of the elastic arm; wherein the switching element keeps the valve closing the gas-releasing hole when the switching element is engaged into the trough in the pressed position, so that the operating arm is fixed to the pressed position and the pressurized gas can continuously flow through the gas-delivering tube and enter the intake channel.
