Setting deflection inlet channel group, the set-up mode of other component is same or similar with other embodiments, and details are not described herein.
It is further preferred that referring to Figure 18, in one embodiment, the hole in the bottom inflow channel 14 of a capsule chamber 1
Diameter is different from other two capsule chamber 1, so that the inlet air flow rate of the capsule chamber 1 is different from other capsule chambers 1.
In some cases, each component of combination product, which needs to reach specific droplet distribution, can just maximize its effect
Fruit, since every kind of component of the utility model is individually released the drug in corresponding capsule chamber 1, by adjusting deflection inlet channel
13, the structure features such as the size of inlet channel 14 and/or outlet passageway 11, position, opening angle and/or quantity are, it can be achieved that right
Different Aerodynamic parameters is respectively set in each capsule chamber 1, to be administered at the same time under the premise of maximize every kind of activity at
The therapeutic effect divided.The present embodiment assigns its different air stream by adjusting the size in 1 bottom inflow channel 14 of capsule chamber
Speed, to influence the droplet distribution of Traditional Chinese medicine capsule powder.
It is the embodiment of another powder inhaler of the utility model, more capsule chambers 1 are by the first glue referring to Figure 19
Capsule room 1a, the second capsule chamber 1b, third capsule chamber 1c and the 4th capsule chamber 1d closely arrange to be caused for a square, described first
Dynamic portion 2a and the second actuation part 2b is disposed on the central axes of square and can be mobile from two sides to centre, first actuating
Portion 2a and the second actuation part 2b includes at least two prickers 21 in the direction of the width, so that the first actuation part 2a punctures the simultaneously
Capsule in one capsule chamber 1a and the second capsule chamber 1b, the second actuation part 2b puncture third capsule chamber 1c and the 4th capsule chamber simultaneously
Capsule in 1d.
The present embodiment by setting four capsule chambers, provide it is a kind of in a manner of separation include combination product four kinds of activity
Component (or mixtures thereof) pill dispenser.Four capsule chambers, which are arranged, causes suction apparatus higher to patient breaths' traffic requirement,
In order to make capsule be fully rotatable drug release, 1 bottom of each capsule chamber of the present embodiment is equipped with deflection inlet channel group, it is described deflect into
Gas channel group is arranged as a fixed blade wheel structure on the whole, to provide spiral gas from bottom to top in user's air-breathing
Stream has effectively promoted capsule rotation drug release, and wherein the concrete shape of blade wheel structure can refer to Figure 10.
The foregoing is merely specific embodiment of the present utility model, are not intended to limit the scope of the utility model.Appoint
What those skilled in the art, the equivalent variations made under the premise of not departing from the conceptions and principles of the utility model, modification
