DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] An automatically resettable smoking paraphernalia includes the following components:

[0035] the outer upper shell 1, wherein the outer upper shell is cylindrical with openings at two ends, the opening at one end of the outer upper shell is provided with the inner flange 1011, and a side wall of the outer upper shell is provided with the pushing key sliding groove 1021;

[0036] the smoking cup 3 provided inside the outer upper shell 1, wherein an outer wall of the smoking cup 3 is provided with the outward protruded annulus 306, a bottom of the smoking cup is provided with the heating element socket 305, the bottom or a wall of the smoking cup is provided with the air inlet hole 303, the wall of the smoking cup is sleeved with the spring 2, and two ends of the spring abut between the inner flange 1011 and the outward protruded annulus 306; and

[0037] the pushing key 5, wherein the pushing key includes the pushing key annulus 501 and the pushing key block 502, the pushing key annulus 501 is engaged with the outward protruded annulus 306, and the pushing key block 502 is provided inside the pushing key sliding groove 1021.

[0038] Preferably, the automatically resettable smoking paraphernalia further includes the outer lower shell 11. The outer lower shell is detachably connected to the outer upper shell 1. The heating element 4 is provided in the outer lower shell, extending in a longitudinal direction. When the outer lower shell 11 and the outer upper shell 1 are assembled, the heating element 4 penetrates through the heating element socket 305 into the smoking cup 3. The outer lower shell 11 is internally provided with the electronic core 13 and the power supply switch 7.

[0039] Preferably, the automatically resettable smoking paraphernalia further includes the middle frame decorating component 6. The middle frame decorating component, the outer upper shell 1, and the outer lower shell 11 are detachably connected to each other. The middle frame decorating component 6 is cup-shaped. An inner cavity of the middle frame decorating component is the smoking cup holding cavity 602. An outer side wall of the middle frame decorating component 6 is fixedly provided with a strip-shaped sheet in the longitudinal direction. An outer edge of the strip-shaped sheet has a shape matched with the pushing key sliding groove 1021. An upper part 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 the pushing key position 603 for containing the pushing key block 502. The hole at the lower part of the strip-shaped sheet is the power supply switch position 604 for containing the power supply switch 7.

[0040] Preferably, the pushing key sliding groove 1021 is a U-shaped notch longitudinally extending along the side wall from the other end of the outer upper shell.

[0041] Preferably, two outward protruded annuli are provided on the outer wall of the smoking cup 3, the two outward protruded annuli are arranged at an interval in the longitudinal direction. An upper outward protruded annulus is used to abut against the spring 2. A lower outward protruded annulus is engaged with the pushing key annulus 501.

[0042] Preferably, the detachable connection includes a snap connection, a thread connection, or a pin connection.

[0043] Preferably, the outer upper shell 1 is made of a thermal insulation material.

[0044] Preferably, an inner wall of the outer upper shell 1 is provided with the protruded strip 102 protruding inward and radially, the reinforcing rib 302 protruding outward and radially is provided between the two outward protruded annuli on the outer wall of the smoking cup 3. The protruded strip and the reinforcing rib are matched with each other, avoiding rotation of the smoking cup and preventing the smoking cup from detaching longitudinally.

[0045] The working principle of the present invention is as below: when the smoking paraphernalia of the present invention is used for smoking, the cigarette can be directly inserted. The electronic core can be turned on by pressing the power supply switch 7 for smoking.

[0046] After finishing smoking, when the pushing key 5 is pushed by a thumb to move upward, the smoking cup 3 is driven to move upward. At the same time, the spring 2 moves upward and is thereby compressed, till the upper part of the smoking cup 3 protrudes out of the outer upper shell 1. Since the protruded strip 102 is engaged with the reinforcing rib 302, a lower part of the smoking cup 3 is tightly held by the outer upper shell 1. At that time, the smoking cup 3 is incapable of rotating or shifting in an oblique direction, so as to readily extract or unload the cigarette. When the pushing key 5 is released, the spring 2 resets, and the smoking cup 3 returns to its original position, i.e., automatically resetting. At that time, a next cigarette can be inserted for smoking. Alternatively, the power supply switch 7 can be pressed to turn off the electronic core, thereby the smoking paraphernalia stops working.
