The invention discloses an
inhalation device which comprises an
inhaler main body, a suction
nozzle, a tank
assembly, a
drying module and a counting module, and the
inhaler main body is provided with a trigger surface; the suction
nozzle is arranged on one side of the
inhaler main body, and a
discharge hole is formed in the suction
nozzle; the tank
assembly is movably arranged in the inhaler main body, the tank
assembly is configured to press out mist, and an outlet of the tank assembly is communicated with the
discharge hole; the
drying module is arranged around the outlet of the tank assembly, and the
drying module is configured to at least dry a channel of the outlet of the tank assembly when the suction device is in the storage state; the counting module is arranged at the
tail part of the tank body, and the counting module is configured to be capable of being pressed by a user to move downwards to the triggering surface and cooperatively perform
dose counting when the
inhalation device is in a delivery state. According to the suction device, the drying chamber is arranged to perform
moisture absorption treatment on the channel of the valve rod, so that deposition or accumulation of pharmaceutical preparations in the channel of the device is limited or basically eliminated, and the service life of the device is prolonged.
