Abstract

A nebulizing device includes a medicament storage module, a nebulizing unit, and a first waterproof gasket. In the medicament storage module, a coupling part is connected with an outer surface of a tubular sidewall and aligned with an outlet of the tubular sidewall, and includes an extension wall and a first recess where the nebulizing unit is disposed. The first waterproof gasket is disposed within the first recess and located on a side of the nebulizing unit farther from the outlet. In the first waterproof gasket, a first opening is disposed adjacent to the nebulizing unit, a second opening is disposed opposite to the first opening and located on a side of the first opening farther from the nebulizing unit, the size of the second opening is greater than that of the first opening, and the annular wall structure is connected to the first opening and the second opening.

First claim

What is claimed is:

1. A nebulizing device, comprising:
a storage module, comprising:
a bottom wall;
a tubular sidewall connected to the circumference of the bottom wall, wherein the tubular sidewall and the bottom wall form an accommodating recess having an upper opening to accommodate a liquid, the tubular sidewall comprises an outlet, and the bottom wall is extended to the outlet; and
a coupling part connected to an outer surface of the tubular sidewall and aligned with the outlet, and comprising an extension wall and a first recess;

a nebulizing unit disposed within the first recess to transform the liquid outputted by the outlet into a plurality of nebulized drops; and
a first waterproof gasket disposed within the first recess and located on a side of the nebulizing unit farther from the outlet, comprising:
a first opening disposed adjacent to the nebulizing unit;
a second opening disposed opposite to the first opening and away from the nebulizing unit, wherein the size of the second opening is greater than that of the first opening; and
an annular wall structure connected to the first opening and the second opening.

2. The nebulizing device as recited in claim 1 , wherein the annular wall structure is extended from the first opening toward the second opening to form a non-horizontal surface.

3. The nebulizing device as recited in claim 1 , wherein the annular wall structure has a concave surface, a flat surface, a jagged surface or a ladder-shaped surface.

4. The nebulizing device as recited in claim 1 , wherein the nebulizing unit comprises a piezoelectric element and a nozzle plate, the piezoelectric element is disposed around the nozzle plate, and the first waterproof gasket tightly abuts on the piezoelectric element.

5. The nebulizing device as recited in claim 4 , further comprising a guiding tube detachably coupled with the coupling part of the storage module.

6. The nebulizing device as recited in claim 5 , wherein the guiding tube comprises a connection portion, an opening and a tube portion, wherein the connection portion is coupled with the extension wall of the coupling part, the opening is correspondingly disposed at or aligned with the nozzle plate, and the guiding tube guides the plurality of nebulized drops sprayed out by the nebulizing unit.

7. The nebulizing device as recited in claim 5 , wherein the coupling part further comprises an annular groove disposed on the extension wall of the coupling part and facing an end surface of the guiding tube.

8. The nebulizing device as recited in claim 7 , further comprising a second waterproof gasket partially disposed within the annular groove and partially extended outwards to cover the end surface of the guiding tube.

9. The nebulizing device as recited in claim 8 , wherein the second waterproof gasket prevents an external liquid from permeating into a region where an electrode is located through the gap between the guiding tube and the coupling part to avoid the short circuit of the electrode assembly.

10. The nebulizing device as recited in claim 1 , further comprising a third waterproof gasket, wherein the third waterproof gasket and the first waterproof gasket form a hermetic space at one end of the first recess.

11. A nebulizer, comprising:
a nebulizing device, comprising:
a storage module, comprising:
a bottom wall;
a tubular sidewall connected to the circumference of the bottom wall, wherein the tubular sidewall and the bottom wall form an accommodating recess having an upper opening to accommodate a liquid, the tubular sidewall comprises an outlet, and the bottom wall is extended to the outlet; and
a coupling part connected to an outer surface of the tubular sidewall and aligned with the outlet, and comprising an extension wall and a first recess;

a nebulizing unit disposed within the first recess to transform the liquid outputted by the outlet into a plurality of nebulized drops and spray them out; and
a first waterproof gasket disposed within the first recess and located on a side of the nebulizing unit farther from the outlet, comprising:
a first opening disposed adjacent to the nebulizing unit;
a second opening disposed opposite to the first opening and located on a side of the first opening farther from the nebulizing unit, wherein the size of the second opening is greater than that of the first opening; and
an annular wall structure connected to the first opening and the second opening; and

a nebulization driving device connecting to and driving the nebulizing unit to spray the nebulized drops.

12. The nebulizer as recited in claim 11 , wherein the annular wall structure is extended from the first opening toward the second opening to form a non-horizontal surface.

13. The nebulizer as recited in claim 11 , wherein the annular wall structure has a concave surface, a flat surface, a jagged surface or a ladder-shaped surface.

14. The nebulizer as recited in claim 11 , wherein the nebulizing unit comprises a piezoelectric element and a nozzle plate, the piezoelectric element is disposed around the nozzle plate, and the first waterproof gasket tightly abuts on the piezoelectric element.

15. The nebulizer as recited in claim 14 , wherein the nebulizing device further comprises a guiding tube which is detachably coupled with the coupling part of the storage module.

16. The nebulizer as recited in claim 15 , wherein the guiding tube comprises a connection portion, an opening and a tube portion, wherein the connection portion is coupled with the extension wall of the coupling part, the opening is correspondingly disposed at or aligned with the nozzle plate, and the guiding tube guides the plurality of nebulized drops sprayed out by the nebulizing unit.

17. The nebulizer as recited in claim 16 , wherein the coupling part further comprises an annular groove which is disposed on the extension wall of the coupling part and faces an end surface of the guiding tube.

18. The nebulizer as recited in claim 17 , wherein the nebulizing device further comprises a second waterproof gasket which is disposed within the annular groove and extended outwards to cover the end surface of the guiding tube.

19. The nebulizer as recited in claim 18 , wherein the second waterproof gasket is extended along a sidewall of the terminal of the extension wall, and a section of the second waterproof gasket has a mushroom shape.

20. The nebulizer as recited in claim 11 , wherein the nebulizing device further comprises a third waterproof gasket, wherein the third waterproof gasket and the first waterproof gasket form a hermetic space disposing with an electrode at one end of the first recess.
