The setting of fixed plate 5 makes rolling disc 4 slide with fixed plate 5 face and face all the time when rotating, has improved pivoted stability. The medicine storage member 6, the inhalation member 7 and the fixing plate 5 may be integrally formed by means of adhesive bonding or the like, but are not limited thereto.

In the inhalation device provided in the present embodiment, when the button member 2 is not pressed, the rotary disk 4 is in the administration position; when the button member 2 is pressed to the end of the stroke, the rotary disk 4 is at the suction position. In other embodiments, the administration site and inhalation site are not limited where they are specifically located. For example, in the process of pressing the button part 2, the rotating disc 4 passes through the administration position and then passes through the inhalation position, and at this time, the powder mist firstly enters the medicine storage groove 41 and then is sucked out by a user through the flow channel 71; or in the process of pressing the button part 2, the rotating disc 4 passes through the suction position and then passes through the administration position, and at the moment, a user firstly sucks out the powder fog agent in the medicine storage groove 41 and then fills new powder fog agent into the medicine storage groove 41 to wait for the next use.

In the inhalation device provided in this embodiment, in the whole use process, the button part 2 is pressed, the rotating disc 4 is pushed to rotate through the tooth engagement structure at the other end of the button part 2, the medicine storage groove 41 on the rotating disc 4 collects powder mist from the medicine storage bin 61 in the medicine storage part 6 and rotates to the input port position of the runner 71, the medicine storage groove 41 is mutually communicated with the runner 71, the runner 71 partially stretches into the inhalation channel 121 on the outer side wall of the cover body part 12, and a patient can inhale the powder mist into the body in a breathing manner by containing the outermost side of the inhalation channel 121, namely, the position corresponding to the output port of the runner 71 in the oral cavity.

The existing powder aerosol administration device in the market generally needs two hands to twist parts so as to realize the administration function. The inhalation device provided by the embodiment can be pressed by one hand, is convenient to operate and is convenient to use.

In the existing powder aerosol drug delivery device in the market, a plurality of drug storage tanks for containing powder aerosol are usually arranged, and certain differences exist in the manufacturing process of the drug storage tanks, and the differences influence the measurement of the powder aerosol, so that the powder aerosol inhaled by a user is different in dosage. The inhalation device provided in this embodiment is provided with only one medicine storage tank 41 for containing powder aerosol, so that the problem of non-quantitative administration caused by the arrangement of a plurality of medicine storage tanks for containing powder aerosol can be avoided.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments. Even if various changes are made to the present utility model, it is within the scope of the appended claims and their equivalents to fall within the scope of the utility model.
