Abstract

An automatically resettable smoking paraphernalia includes the following components: an outer upper shell, a smoking cup provided inside the outer upper shell, a pushing key, and a spring, etc., wherein the smoking cup, the spring, the outer upper shell can be detached and replaced as a whole, the smoking cup can stick out of the outer upper shell by a distance to extract and unload the cigarette, and then automatically reset. Besides, the smoking cup is hidden inside the upper outer shell, so as to prevent the exposed smoking cup with an excessively high temperature from burning users, meanwhile avoiding a risk of losing the smoking cup.

First claim

What is claimed is:

1 . An automatically resettable smoking paraphernalia, comprising the following components:
an outer upper shell, wherein a side wall of the outer upper shell is provided with a pushing key sliding groove, and an inner wall of the outer upper shell is provided with a protruded strip; a smoking cup provided inside the outer upper shell, wherein an outer wall of the smoking cup is provided with two outward protruded annuli, a reinforcing rib is provided between the two outward protruded annuli on the outer wall of the smoking cup, a bottom of the smoking cup is provided with a heating element socket, and the outer wall of the smoking cup is sleeved with a spring; and a pushing key, wherein the pushing key comprises a pushing key annulus and a pushing key block, the pushing key annulus is engaged with one of the two outward protruded annuli, and the pushing key block is provided inside the pushing key sliding groove; wherein the protruded strip and the reinforcing rib are matched with each other, wherein when the pushing key is pushed upward, the smoking cup is moved upward, which causes the spring to move upward and be compressed, and when the pushing key is pushed until an upper part of the smoking cup protrudes out of the outer upper shell, the protruded strip engages with the reinforcing rib, which causes a lower part of the smoking cup tightly held by the outer upper shell and locks the smoking cup from rotating or shifting in an oblique direction; and when the pushing key is released, the spring resets the smoking cup to an original position.

2 . The automatically resettable smoking paraphernalia according to claim 1 , further comprising an outer lower shell, wherein the outer lower shell is detachably connected to the outer upper shell, a heating element is provided in the outer lower shell, and the heating element is configured to penetrate through the heating element socket into the smoking cup.

3 . The automatically resettable smoking paraphernalia according to claim 2 , wherein
the outer lower shell is further internally provided with an electronic core and a power supply switch.

4 . The automatically resettable smoking paraphernalia according to claim 2 , further comprising a middle frame decorating component, wherein the middle frame decorating component, the outer upper shell, and the outer lower shell are detachably connected to each other.

5 . The automatically resettable smoking paraphernalia according to claim 4 , wherein the middle frame decorating component is cup-shaped, an inner cavity of the middle frame decorating component is a smoking cup holding cavity, an outer side wall of the middle frame decorating component is fixedly provided with a strip-shaped sheet, an outer edge of the strip-shaped sheet has a shape matched with the pushing key sliding groove, an upper part of the strip-shaped sheet and a lower part of the strip-shaped sheet are respectively provided with a hole, the hole at the upper part of the strip-shaped sheet is a pushing key position for containing the pushing key block, the hole at the lower part of the strip-shaped sheet is a power supply switch position for containing a power supply switch.

6 . The automatically resettable smoking paraphernalia according to claim 4 , wherein the middle frame decorating component, the outer upper shell, and the outer lower shell are detachably connected to each other with a snap connection, a thread connection, or a pin connection.

7 . The automatically resettable smoking paraphernalia according to claim 1 , the bottom of the smoking cup is provided with an air inlet hole.

8 . The automatically resettable smoking paraphernalia according to claim 1 , a wall of the smoking cup is provided with an air inlet hole.

9 . The automatically resettable smoking paraphernalia according to claim 1 , wherein the outer upper shell is cylindrical with openings at two ends, the opening at a first end of the outer upper shell is provided with an inner flange.

10 . The automatically resettable smoking paraphernalia according to claim 9 ,
wherein the pushing key sliding groove is a U-shaped notch extending along the side wall of the outer upper shell from a second end of the outer upper shell.

11 . The automatically resettable smoking paraphernalia according to claim 1 , wherein the two outward protruded annuli are arranged at an interval in a longitudinal direction, an upper outward protruded annulus of the two outward protruded annuli is configured to abut against the spring, and a lower outward protruded annulus of the two outward protruded annuli is configured to engage with the pushing key annulus.

12 . The automatically resettable smoking paraphernalia according to claim 1 , wherein the outer upper shell is made of a thermal insulation material.
