Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 to 2, the capsule type dry powder inhaler 01 according to the embodiment of the present utility model has a very simple overall structure by pulling out the nozzle cap 10, pinching the housing 11 with two fingers, and holding the nozzle 12.

Referring to fig. 1 to 2, a capsule type dry powder inhaler 01 according to an embodiment of the present utility model includes a nozzle cover 10, a housing 11, and a nozzle 12, wherein the nozzle cover 10 can be pulled out from the nozzle 12 and separated from the housing 11; the fine hole 20 at the top of the suction nozzle 12 is a channel for the dry powder agent to leave the inhaler 01; the identifier arrow 21 on the suction nozzle cover 10 indicates the suction nozzle cover 10 and the direction in which the suction nozzle cover 10 is pulled out; the dry powder inhaler 01 is simple to operate and convenient to use.

Referring to fig. 3, a cross-sectional view of a capsule type dry powder inhaler 01 according to an embodiment of the present utility model is characterized in that the inhaler 01 includes a turbulence valve 13, an elastic valve 14 and a supporting frame 15 on the inner side of the suction nozzle 12 enclosed with the housing 11. The turbulence valve 13 is connected with the suction nozzle 12, the supporting frame 15 is connected with the shell 11, and the elastic valve 14 is arranged on the supporting frame 15; the space enclosed by the elastic valve 14, the supporting frame 15 and the suction nozzle 12 is a medicine bin 22; the bottom of the housing 11 is provided with an air inlet opening 23. The inner side of the nozzle cover 10 is closely contacted and matched with the outer side of the nozzle 12, and the fine holes 20 at the top of the nozzle 12 are sealed before the nozzle cover 10 is pulled out.

Referring to fig. 3 to 5, the capsule type dry powder inhaler 01 operates on the principle that when the mouthpiece 12 is contained to take the dry powder medicament, the skirt 24 of the elastic valve 14 is turned up under the action of suction, air flows into the medicine compartment 22, and the dry powder medicament enters the oral cavity through the pores 20 at the top of the mouthpiece 12 under the action of air flow. Another function of the elastic valve 14 is that it seals against the support 15 by elasticity when no air flow is pushing. The support 15 is provided with a vent hole 25, when negative pressure is formed in the inhaler 01, external air flows through the air inlet hole 23, and then the skirt 24 of the elastic valve 14 is turned up by the vent hole 25. The elastic valve 14 is fixedly connected with the supporting frame 15 by an elastic column 26 on the elastic valve 14 through elasticity.

Referring to fig. 6 and 7, the turbulence valve 13 has one function of using the convex arc surface 30 of the turbulence valve 13 to reflux the air flow from the turned-up skirt 24 of the elastic valve 14 into the medicine compartment 22, and blowing up the dry powder medicine accumulated in and near the center of the elastic valve 14; the second function is to disperse the dry powder agent falling back into the nozzle 12 due to shaking, carrying, etc. at the upper position 27 of the turbulence valve 13 by using the concave arc surface 31 of the turbulence valve 13.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
