TECHNICAL FIELD

The present invention belongs to the field of novel cigarette products, specifically relates to an automatically resettable smoking paraphernalia.

BACKGROUND

With smoking paraphernalia products for novel cigarettes stepping into the market, feedback from consumers is increasingly detail-oriented, and higher requirements for the humanized designs targeting at various components of the smoking paraphernalia are raised. Thereinto, inserting and extracting cigarettes is a focus of research for the researchers. For the existing smoking paraphernalia products for novel cigarettes, a cigarette generally needs to be manually inserted, and the cigarette sticking out of the heating cavity is manually disassembled after smoking. The operation mode readily breaks the cigarette or makes fragments of the cigarette remain in the heating cavity, greatly increasing difficulties in the subsequent cleaning.

A Chinese patent of Philip Morris International having an application number of 201280063987.0 discloses an extractor for a smoke product, wherein the extractor is formed by riveting two components, the outer shell is provided with a protrusion to handily fix to a main body, and an inner sleeve is provided with a step to handily engage with an upper end portion of the heating cavity. The extractor needs a relatively large thrust applied upward along the outer shell to realize an unloading process of the cigarette, and after completing the unloading process of the cigarette, the outer shell should be applied with a downward external force to reset, failing to automatically reset. The operating process is excessively complicated, meanwhile increases a risk that the outer shell may get misplaced after unloading the cigarette. Moreover, the temperature of the smoking cup after heating is excessively high and may readily burn the user, greatly lowering the user's smoking experience.

SUMMARY

To solve the above-mentioned problems, the present invention provides an automatically resettable smoking paraphernalia to avoid the complicated operation process of manually extracting and unloading the cigarette and resetting. The whole upper cover assembly is detachable and replaceable, solving the problem that the cigarette extracting and unloading mechanism may burn users and may get misplaced, which improves the smoking experience.

The objective of the present invention is implemented by the following technical solutions.

An automatically resettable smoking paraphernalia includes the following components:

an outer upper shell, wherein the outer upper shell is cylindrical with openings at two ends, the opening at one end is provided with an inner flange, a side wall of the outer upper shell is provided with a pushing key sliding groove;

a smoking cup provided inside the outer upper shell, wherein an outer wall of the smoking cup is provided with an outward protruded annulus, a bottom of the smoking cup is provided with a heating element socket, the bottom or a wall of the smoking cup is provided with an air inlet hole, the wall of the smoking cup is sleeved with a spring, two ends of the spring abut between the inner flange and the outward protruded annulus; and

a pushing key, wherein the pushing key includes a pushing key annulus and a pushing key block, the pushing key annulus is engaged with the outward protruded annulus, and the pushing key block is provided inside the pushing key sliding groove.

Preferably, the automatically resettable smoking paraphernalia further includes an outer lower shell. The outer lower shell is detachably connected to the outer upper shell. A heating element is provided inside the outer lower shell, extending in a longitudinal direction. When the outer lower shell and the outer upper shell are assembled, the heating element penetrates through the heating element socket into the smoking cup. The outer lower shell is further internally provided with an electronic core and a power supply switch.

Preferably, the automatically resettable smoking paraphernalia further includes a middle frame decorating component. The middle frame decorating component, the outer upper shell, and the outer lower shell are detachably connected to each other.

Preferably, 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 in the longitudinal direction. An outer edge of the strip-shaped sheet has a shape matched with the pushing key sliding groove. 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 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 containing position for containing the power supply switch7.

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

Preferably, two outward protruded annuli are provided on the outer side wall of the smoking cup, and 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. A lower outward protruded annulus is engaged with the pushing key annulus.

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

Preferably, the outer upper shell is made of a thermal insulation material.

Preferably, an inner wall of the outer upper shell is provided with a protruded strip protruding inward and radially. A reinforcing rib protruding outward and radially is provided between the two outward protruded annuli on the outer wall of the smoking cup. 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.

The working principle of the present invention is as below. After finishing smoking using the smoking paraphernalia according to the present invention, the pushing key is pushed by a thumb to move upward, thus driving the smoking cup to move upward. Meanwhile, the spring moves upward and is thereby compressed, till an upper part of the smoking cup protrudes out of the outer upper shell. Owing to an engagement between the protruded strip and the reinforcing rib, a lower part of the smoking cup is tightly held by the outer upper shell, at that time, the smoking cup is incapable of rotating or shifting in an oblique direction, thus the cigarette is readily extracted and unloaded. When the pushing key is released, the spring resets, the smoking cup returns back to its original position, i.e., automatically resetting; at that time, the user can insert the next cigarette for smoking, alternatively, the user may press the power supply switch to turn off the electronic coil, thereby the smoking paraphernalia stops working.

The present invention has the following advantages.

(1) The present invention provides an automatically resettable smoking paraphernalia, wherein the smoking cup, the spring, and the outer upper shell can be disassembled and replaced as a whole, so as to conveniently clean the heating element and replace the heating cavity.

(2) The present invention provides an automatically resettable smoking paraphernalia, wherein the bottom of the smoking cup contacts the pushing key, when the pushing key is moved upward, the smoking cup moves upward, the spring is compressed, and the smoking cup protrudes out of the outer upper shell by a distance, so as to readily extract and unload the cigarette; when the pushing key is released, the smoking cup resets with the spring.

(3) The present invention provides an automatically resettable smoking paraphernalia, wherein the smoking cup is hidden inside the outer upper shell to prevent the exposed smoking cup with excessively high temperature from burning the user. Besides, since the smoking cup is limited inside the outer upper shell in the whole using process, the risk that the smoking cup may be detached and misplaced is avoided.
