The slider joint in the sunk part of track structure of moving member 7 below, and the slider can slide in the track structure.

When the rotating disc 9 rotates, the moving member 7 cannot rotate along with the guide groove 6 due to the stopping and limiting of the guide groove, so that the relative sliding is generated between the track structure and the sliding member; because the moving member 7 and the guide groove 6 can slide relatively, the sliding member is pushed by the spiral track structure to move towards/away from the center of the spiral along the guide groove 6, namely, towards/away from the heating member 3, and clamping/loosening operation is performed on the smoking substrate 14 in the plug-in cavity. It can be understood that the moving member 7 will slide forward/backward along the guide slot 6 due to the pushing of the rotating disc 9, so that the rotating motion is converted into the horizontal motion.

It will be appreciated that the sliding member may be configured according to the size of the recess of the track structure, and may have a certain curvature to facilitate relative sliding. The track structure when slider is for whole spiral, its size is less to the self structure adaptation of slider is sunken of the track structure of different circles, possesses the feasibility, can accomplish the functional requirement that above-mentioned joint promoted.

For the track structure, the distance between two adjacent turns is the same, but the radius thereof gradually decreases from the outside to the inside. The angle of the force can be changed to provide sufficient power for the horizontal movement of the moving member 7.

Based on the mounting hole 93 of central point, gear portion 92 can include a plurality of awl teeth, and a plurality of awl teeth use mounting hole 93 as the centre of a circle, evenly distributed in the back of rolling disc 92, and every awl tooth all is perpendicular to mounting hole 93 to form the face gear structure of annular distribution. The number or the spacing of the bevel gears is adjusted, a follow-up gear 10 which can be meshed with the annular distributed gear part 92 is designed in a matched mode, and the follow-up gear 10 can be used for driving the rotating disc 9 to rotate and can also be used for stabilizing the installation position of the rotating disc 9.

The follower gear 10 may include a fixed shaft and a meshing gear, wherein the meshing gear is capable of meshing with the gear portion 92.

For the rotational stability of the rotating disc 9, a plurality of rotating holes may be formed in the inner annular wall 42 and the outer annular wall 41, and the rotating holes in the inner annular wall 42 and the rotating holes in the outer annular wall 41 are arranged in a one-to-one correspondence, so that two ends of a fixed shaft of one follower gear 10 may be installed between the two corresponding rotating holes and form a rotating connection relationship therewith, the fixed shaft is perpendicular to the outer annular wall 41 and the inner annular wall 42, and the meshing teeth on the follower gear 10 mesh with and abut against the gear portion 92. Can set up a plurality of follower gears 10 and be located the below of rolling disc 9 and gear portion 92 meshing butt, upwards support the rotational stability of rolling disc 9 for rolling disc 9 is in the horizontality all the time when rotating, and simultaneously, a plurality of follower gears 10 can also backstop rolling disc 9 and drop in the diapire rampart structure of base 4.

As for the adjusting member 11, the adjusting member 11 may include a follower gear 10, a rotating portion. Wherein the rotating part comprises a connecting rod and a rotating block. One end of a fixed shaft of the follow-up gear 10 is vertically and rotatably connected with the inner annular wall 42, the other end of the fixed shaft is fixedly connected with one end of a connecting rod, and the other end of the connecting rod extends to the outside of the shell 1 through a through hole on the outer wall ring 41 and then is fixedly connected with a rotating block, so that a user can rotate the rotating block outside the shell 1 to urge the rotating disc 9 inside the shell 1 to rotate along with the rotating block.

It can be understood that after the meshing teeth of the follower gear 10 of the adjusting member 11 are meshed with the rotating disc 9, the follower gear 10 at other positions can be matched to have a good supporting effect on the rotating disc 9, so as to ensure the meshing effect.

It can be understood that the number of the follower gears 10 between the outer annular wall 41 and the inner annular wall 42 may be three, and one of the three follower gears 10 with an appropriate position is selected to be fixedly connected with the rotating part of the adjusting member 11. The three follower gears 10 may be evenly distributed and in the same plane, that is, the included angle between two adjacent follower gears 10 is 120 °.

It can be understood that the plurality of moving members 7 can be driven by the rotating disc 9 to move simultaneously, so as to stably clamp the fuming base body 14 in all directions. That is, when the moving member 7 moves close to the heating member 3 along the direction of the guide groove 6, the plurality of moving members 7 can clamp the fuming substrate 14 mutually without the cooperation of the heating member 3; when the moving member 7 moves away from the heating member 3 along the direction of the guide groove 6, the plurality of moving members 7 gradually release the fuming substrate 14.

It can be understood that the rotation direction of the adjusting member 11 can be designed according to actual conditions, and the rotation direction of the clamping/releasing can also be marked on the housing 1, so that the operation of a user is convenient.

In the embodiment of the invention, the interior of the shell 1 at least comprises a power supply module and a control module. Wherein:

the power supply module at least comprises a power supply unit, a battery unit and a charging unit, wherein the power supply unit is used for supplying electric energy to other power-requiring units and modules of the device; the battery unit is used for storing electric quantity; the charging unit is used for circularly charging.

The control module at least comprises a heating unit and a display unit, wherein the heating unit is used for generating heat through electric energy; the display unit is used for displaying the residual electric quantity, the pumping time and the like.

Furthermore, the device can also be provided with a key 13 on the shell 1 as a master control switch of the device.

The above-described aspects may be implemented individually or in various combinations, and such variations are within the scope of the present invention.
