The invention discloses a capsule type dry powder inhaler, which relates to a medicine taking device, comprising a sleeve, a bottom shell and a suction nozzle. The shell cooperates to form an active cavity, the suction nozzle is slid to be placed in the active cavity, and a pull-out mechanism is provided between the suction nozzle and the sleeve. The pull-out mechanism includes an elastic reset piece and a pull piece, and a through groove is opened on the sleeve; A sealing cover is hinged on the sleeve, and a transmission structure transmission connection is provided between the sealing cover and the elastic reset part; in the initial state, the pulling part is in the through groove, the pulling part is clamped with the elastic restoring part, and the elastic restoring part stores elastic potential energy. The sealing cover and the sleeve cooperate with the cover to set the suction nozzle, and the force is applied to the pulling part so that the suction nozzle emerges from the sleeve and the sealing cover is opened at the same time. The mouth is placed in the oral cavity so as to take the medicine, the direct contact of the hand with the suction nozzle is reduced, and the pollution to the suction nozzle is reduced.
Description
technical field [0001] The present invention relates to a medicine taking device, more specifically, it relates to a capsule type dry powder inhaler. Background technique [0002] Dry powder inhaler is a device used to cooperate with the inhalation of medicines for the treatment of asthma and other diseases. The inhalation medicine is made into micronized medicine or stored in capsules, vesicles or multi-dose with carriers, and is actively inhaled by the patient to the lungs by the dry powder inhaler. [0003] The existing Chinese patent with the publication number CN205007396U discloses a capsule-type dry powder inhaler, which includes a housing and a bottom cover. The housing includes a suction nozzle, a screen, a separation chamber and an air flow device. The screen is located under the suction nozzle. The air flow device includes the bottom of the casing, that is, the air inlet on the bottom cover. On the outside of the casing, there are knobs, knob glands and reinforcin...
