Abstract

A nebulizer with a press-type medicine cup is provided. The nebulizer includes a body, a medicine cup, an engagement structure, and a multi-directional resilient member. The engagement structure includes an inner protruding base and an outer protruding block disposed outside the inner protruding base. The inner protruding base and the outer protruding block extend from the body and the medicine cup. The inner protruding base includes a cavity inside and includes two through holes. The outer protruding block includes two engagement grooves. The multi-directional resilient member is installed in the cavity and includes a press element, two straight resilient arms extend from the press element, two oblique resilient arms are bent from the two straight resilient arms, and each oblique resilient arm has a block member. The two block members are inserted through the two through holes to be engaged with the two engagement grooves.

First claim

What is claimed is:

1. A nebulizer with a press-type medicine cup, comprising:
a body;
a medicine cup;
an engagement structure, the engagement structure including an inner protruding base and an outer protruding block disposed outside the inner protruding base, the inner protruding base extending from one of the body and the medicine cup, the outer protruding block extending from the other one of the body and the medicine cup, the inner protruding base including a cavity inside and including an opening and two through holes communicating with the cavity, the outer protruding block including two engagement grooves; and
a multi-directional resilient member installed in the cavity, the multi-directional resilient member including a press element, two straight resilient arms extending from the press element, two oblique resilient arms being bent backward from the two straight resilient arms, a block member being disposed at a distal end of each of the oblique resilient arms, the press element being inserted through and exposed from the opening, the two block members being inserted through the two through holes and engaged with the two engagement grooves respectively, wherein when the press element is pressed, the two block members are driven to retract into the two through holes to be released from the two engagement grooves, so that the medicine cup is detachably connected to the body.

2. The nebulizer with the press-type medicine cup according to claim 1 , further comprising a restoring assembly, the restoring assembly including a clamping plate and a restoring spring, the clamping plate being disposed in the cavity, the restoring spring being clamped between the clamping plate and the press element.

3. The nebulizer with the press-type medicine cup according to claim 2 , wherein a fixation rod extends from the press element and is received in the cavity, and the restoring spring is a helical spring, and the helical spring receives the fixation rod.

4. The nebulizer with the press-type medicine cup according to claim 1 , wherein the engagement structure further includes two first blockers, the two first blockers are formed at respective inner surfaces of the two through holes away from the press element, and the two first blockers are in contact with the two block members respectively.

5. The nebulizer with the press-type medicine cup according to claim 4 , wherein the engagement structure further includes two second blockers, the two second blockers are formed at the respective inner surfaces of the two through holes close to the press element, and the two second blockers are in contact with the two block members respectively.

6. The nebulizer with the press-type medicine cup according to claim 1 , wherein each of the oblique resilient arms includes an outer oblique side, the engagement structure further includes two first blockers, and the two first blockers are disposed in the cavity and are in contact with the respective outer oblique sides of the two oblique resilient arms.

7. The nebulizer with the press-type medicine cup according to claim 6 , wherein the engagement structure further includes two second blockers, the two second blockers are formed at respective inner surfaces of the two through holes close to the press element, and the two second blockers are in contact with the two block members respectively.

8. The nebulizer with the press-type medicine cup according to claim 1 , wherein when the press element is exposed from the opening, each of the oblique resilient arms forms a first acute angle with respect to a corresponding one of the straight resilient arms.

9. The nebulizer with the press-type medicine cup according to claim 8 , wherein when the press element is pressed, each of the oblique resilient arms forms a second acute angle with respect to a corresponding one of the straight resilient arms, and the second acute angle is smaller than the first acute angle.

10. The nebulizer with the press-type medicine cup according to claim 1 , wherein the medicine cup includes a spray hole, a medicinal liquid chamber is disposed inside the medicine cup, and the medicinal liquid chamber communicates with the spray hole.

11. The nebulizer with the press-type medicine cup according to claim 10 , wherein the body is a power supply body, the power supply body includes a switch and a plurality of electrodes, the medicine cup includes a plurality of conductive portions, and each of the electrodes is electrically connected to each of the conductive portions.
