Abstract

A retractable mouthpiece includes an upper cover of a hollow structure with an receiving cavity, a lower cover that fits with the upper cover, a fastener arranged between the upper cover and the lower cover and housed inside the receiving cavity, a smoking pipe housed inside the receiving cavity, and an elastic component arranged between the smoking pipe and the lower cover. The fastener is sleeved on the smoking pipe, and the smoking pipe is extended out of the upper cover or retracted within the upper cover when the smoking pipe is pressed or rotated. The retractable mouthpiece is both healthy and convenient. An electronic cigarette with the retractable mouthpiece is disclosed.

First claim

What is claimed is:

1. A retractable mouthpiece, comprising:
an upper cover of a hollow structure with a receiving cavity;
a lower cover that fits with the upper cover;
a fastener arranged between the upper cover and the lower cover and housed inside the receiving cavity;
a smoking pipe housed inside the receiving cavity; and
an elastic component arranged between the smoking pipe and the lower cover,
wherein the fastener is sleeved on the smoking pipe, and the smoking pipe is extended out of the upper cover or retracted within the upper cover when the smoking pipe is pressed and/or rotated.

2. The retractable mouthpiece according to claim 1 , wherein the fastener includes an upper surface, a lower surface arranged opposite to the upper surface, a plurality of upper clamping components extending upward from the upper surface, and a plurality of lower clamping components extending downward from the lower surface.

3. The retractable mouthpiece according to claim 2 , wherein each upper clamping component includes an upper protruding part protruding upward from the upper surface and an upper clamping part protruding outward from the upper protruding part, each lower clamping component includes a lower protruding part protruding downward from the lower surface and a lower clamping part protruding outward from the lower protruding part, both sides of each upper protruding part and each upper clamping part are inwardly slanted along a direction of an outer surface to an inner surface of the fastener, and both sides of each lower protruding part and each lower clamping part are inwardly slanted along the direction of the outer surface to the inner face of the fastener.

4. The retractable mouthpiece according to claim 2 , wherein the upper cover includes an upper cover body, an inner wall of a lower part of the upper cover body is provided with a protruding part protruding inward, the protruding part is provided with a protruding inner wall, the upper cover further includes a boss protruding inward from the protruding inner wall, and the upper clamping components are adapted to be engaged with the boss or abut against the boss when the smoking pipe is retracted.

5. The retractable mouthpiece according to claim 4 , wherein the lower clamping components are adapted to be engaged with the boss when the smoking pipe is extended.

6. The retractable mouthpiece according to claim 4 , wherein the upper clamping components are adapted to be separated from the boss by the elastic component when the smoking pipe is pressed, and the smoking pipe is extended out of the upper cover.

7. The retractable mouthpiece according to claim 6 , wherein the upper clamping components are adapted to be abut against the boss when the smoking pipe is pressed, and the smoking pipe is retracted into the receiving cavity.

8. The retractable mouthpiece according to claim 4 , wherein the upper clamping components are adapted to be separated from the boss when the smoking pipe is rotated, and the smoking pipe is extended out of the upper cover.

9. The retractable mouthpiece according to claim 8 , wherein the upper clamping components are adapted to be engaged with the boss or abut against the boss when the smoking pipe is pressed and then rotated, and the smoking pipe is retracted into the receiving cavity.

10. The retractable mouthpiece according to claim 2 , wherein the upper clamping components and the lower clamping components are arranged in a staggered manner or in an alignment manner in a axial direction.

11. The retractable mouthpiece according to claim 1 , wherein the upper cover and/or the smoking pipe are provided with an indicator indicating a position to be rotated and/or pressed.

12. An electronic cigarette, comprising:
a retractable mouthpiece comprising:
an upper cover of a hollow structure with a receiving cavity;
a lower cover that fits with the upper cover;
a fastener arranged between the upper cover and the lower cover and housed inside the receiving cavity;
a smoking pipe housed inside the receiving cavity; and
an elastic component arranged between the smoking pipe and the lower cover,
wherein the fastener is sleeved on the smoking pipe, and the smoking pipe is extended out of the upper cover or retracted within the upper cover when the smoking pipe is pressed and/or rotated.

13. The electronic cigarette according to claim 12 , wherein the fastener includes an upper surface, a lower surface arranged opposite to the upper surface, a plurality of upper clamping components extending upward from the upper surface, and a plurality of lower clamping components extending downward from the lower surface.

14. The electronic cigarette according to claim 13 , wherein each upper clamping component includes an upper protruding part protruding upward from the upper surface and an upper clamping part protruding outward from the upper protruding part, each lower clamping component includes a lower protruding part protruding downward from the lower surface and a lower clamping part protruding outward from the lower protruding part, both sides of each upper protruding part and each upper clamping part are inwardly slanted along a direction of an outer surface to an inner surface of the fastener, and both sides of each lower protruding part and each lower clamping part are inwardly slanted along the direction of the outer surface to the inner face of the fastener.

15. The electronic cigarette according to claim 13 , wherein the upper cover includes an upper cover body, an inner wall of a lower part of the upper cover body is provided with a protruding part protruding inward, the protruding part is provided with a protruding inner wall, the upper cover further includes a boss protruding inward from the protruding inner wall, and the upper clamping components are adapted to be engaged with the boss or abut against the boss when the smoking pipe is retracted.

16. The electronic cigarette according to claim 15 , wherein the lower clamping components are adapted to be engaged with the boss when the smoking pipe is extended.

17. The electronic cigarette according to claim 15 , wherein the upper clamping components are adapted to be separated from the boss by the elastic component when the smoking pipe is pressed, and the smoking pipe is extended out of the upper cover.

18. The electronic cigarette according to claim 17 , wherein the upper clamping components are adapted to be abut against the boss when the smoking pipe is pressed, and the smoking pipe is retracted into the receiving cavity.

19. The electronic cigarette according to claim 15 , wherein the upper clamping components are adapted to be separated from the boss when the smoking pipe is rotated, and the smoking pipe is extended out of the upper cover.

20. The electronic cigarette according to claim 19 , wherein the upper clamping components are adapted to be engaged with the boss or abut against the boss when the smoking pipe is pressed and then rotated, and the smoking pipe is retracted into the receiving cavity.
