For example, as shown in fig. 9, if the diameter-variable adjusting rod 52 is replaced with an elastic metal piece 55 (diameter-variable adjusting piece), the same control effect can be achieved by replacing the diameter-variable adjusting valve 53 with a hinge 56.

The axial fitting is also called length fitting, as shown in fig. 10, the electromagnet 4 generates magnetic force with the same polarity as the permanent magnet 21 on the cock 3, and the magnetic force acts on the permanent magnet 21 of the cock 3 to push the cock 3 forward until the cock 3 is blocked by one end of a cigarette, so that the cock is closed with the front end of the cigarette.

1. A heating non-combustion device comprises a hollow device, and is characterized in that a heating cavity into which a heating object can be inserted is arranged in the hollow device;

The heating cavity comprises a cavity structure formed by surrounding of film heating sheets, and the film heating sheets are used for heating objects in the cavity structure;

The film heating sheet comprises an insulating heat conduction film and a heating wire array, wherein the insulating heat conduction film surrounds the inner wall of the cavity structure, the heating wire array is arranged on the outer side of the inner wall formed by the insulating heat conduction film, and the inner wall formed by the insulating heat conduction film is used for containing the heating object.

2. The heated non-combustion device as recited in claim 1 wherein the insulating and thermally conductive film is a polyimide film.

3. The heated non-combustion device of claim 1, wherein the array of heating wires comprises an array of longitudinal heating wires substantially parallel to a radial direction and/or an array of transverse heating wires substantially perpendicular to a radial direction.

4. a device for heating incombustible according to claim 3, wherein the array of longitudinal heating wires and the array of transverse heating wires are separated by a polyimide film.

5. The heated non-combustion apparatus of claim 4, wherein the longitudinal heater wire array is closer to the inner wall than the transverse heater wire array.

6. The heating non-combustion device as claimed in claim 1, wherein a pintle is further provided on the central axis of the heating chamber for heating the object to be heated.

7. The heated non-combustion device of claim 6, wherein the pintle is wrapped by an insulating heat conducting film, provided with independent electrical input leads, capable of independent electrical heating.

8. The heating non-combustion device as claimed in claim 1, wherein a diameter-variable adjusting means is provided between the outer wall of the hollow means and the film heating sheets for adjusting the inner diameter of the cavity structure surrounded by the film heating sheets to fit the outer diameter of the object to be heated inserted into the cavity structure.

9. The heated non-combustion device of claim 8, wherein the reducing adjustment means comprises:

One or more reducing press sheets configured to press the film heating sheet from an outside of the cavity structure;

Each reducing tabletting is connected with the shell of the hollow device through two reducing adjusting rods, a reducing adjusting valve is arranged between the two reducing adjusting rods, and when the reducing adjusting valve rotates, the two reducing adjusting rods deform through extrusion, so that the position of the reducing tabletting is driven to change.

10. a device according to any one of claims 1 to 9, wherein the heated matter is tobacco rods.
