Abstract

A nebulizer includes a medicament storage module and a nebulizing unit. The medicament storage module includes an inclined bottom wall, a tubular sidewall, and a guiding part. The inclined bottom wall is inclined at an inclination angle. The tubular sidewall is connected with a periphery of the inclined bottom wall. A storage chamber is defined by the inclined bottom wall and the tubular sidewall collaboratively, and a liquid medicament is accommodated within the storage chamber. The tubular sidewall has an outlet, and the inclined bottom wall is extended downwardly to the outlet. The guiding part is arranged around a junction between the inclined bottom wall and the tubular sidewall. The nebulizing unit is disposed on the medicament storage module and aligned with the outlet. The liquid medicament outputted from the outlet is nebulized into a plurality of mist droplets by the nebulizing unit.

Claims

1. A nebulizer, comprising:

a medicament storage module comprising;

an inclined bottom wall inclined at an inclination angle with respect to a horizontal plane;

a tubular sidewall connected with a periphery of the inclined bottom wall, wherein a storage chamber with a top entrance is defined by the inclined bottom wall and the tubular sidewall collaboratively, and a liquid medicament is accommodated within the storage chamber, wherein the tubular sidewall has an outlet, and the inclined bottom wall is extended downwardly to the outlet; and

a guiding part arranged around a junction between the inclined bottom wall and the tubular sidewall; and

a nebulizing unit disposed on the medicament storage module and aligned with the outlet, wherein the liquid medicament outputted from the outlet is nebulized into a plurality of mist droplets by the nebulizing unit.

2. The nebulizer according to claim 1, wherein the inclination angle is in a range between 3 and 30 degrees.

3. The nebulizer according to claim 1, wherein the inclination angle is in a range between 5 and 15 degrees.

4. The nebulizer according to claim 1, wherein the outlet has a first opening and a second opening, wherein the first opening is open to an inner surface of the tubular sidewall and aligned with a notch of the guiding part, and the second opening is open to an outer surface of the tubular sidewall.

5. The nebulizer according to claim 4, wherein both sides of the notch of the guiding part have beveled edges.

6. The nebulizer according to claim 1, wherein the guiding part is a C-shaped curvy structure.

7. The nebulizer according to claim 1, wherein the outlet is close to a lowest position of a bottom surface of the storage chamber.

8. The nebulizer according to claim 1, wherein the medicament storage module further comprises an upper cover, wherein the upper cover is pivotally coupled to the tubular sidewall for sheltering the top entrance of the storage chamber.

9. The nebulizer according to claim 8, wherein the tubular sidewall further comprises at least one first engaging element, and the upper cover comprises at least one second engaging element corresponding to the at least one first engaging element, wherein the at least one first engaging element and the at least one second engaging element are engaged with each other.

10. The nebulizer according to claim 1, wherein the medicament storage module further comprises a coupling part, and the coupling part is connected with an outer surface of the tubular sidewall and aligned with the outlet, wherein the coupling part comprises an extension wall and a first recess, and the nebulizing unit is disposed within the first recess.

11. The nebulizer according to claim 10, further comprising a conduit, wherein the conduit is detachably connected with the coupling part of the medicament storage module.

12. The nebulizer according to claim 1, wherein a second recess is formed in a top edge of the tubular sidewall, and a waterproof gasket is accommodated within the second recess.
