The invention provides a rotary friction assembly, a heating non-combustion tobacco device and a control method of the heating non-combustion tobacco device, and relates to the technical field of heating non-combustion tobacco. The device comprises a rotating piece and a heating piece matched with the rotating piece; the heating piece is provided with a friction cavity, and at least part of the rotating piece extends into the friction cavity; a rotating part, one end of the rotating part is provided with a driving part used for being matched with an external part, the other end of the rotating part is provided with a friction part, the friction part is provided with at least two rotating pieces, and the size of each rotating piece is larger than that of the friction cavity so that the friction part can extrude the inner wall of the friction cavity; the rotating piece is configured to rub with the friction cavity when the rotating piece rotates along with the external piece, so that the temperature of the heating piece rises. Therefore, the problem that in the prior art, axial force needs to be applied to the heating piece through a spring, so that the heating needle component and the motor shaft can be kept tightly attached, and consequently the stress of the heating piece is unbalanced is solved.
Description
technical field [0001] The invention relates to the technical field of heat-not-burn tobacco, in particular to a rotating friction assembly, a heat-not-burn tobacco device and a control method thereof. Background technique [0002] For example, the Chinese patent CN109619692A discloses "a method and device for heating non-burning tobacco by inserting rotary friction", which includes a device casing, a battery, a battery charging module, a circuit control module, a motor, a vacuum soundproof cylinder, a heating needle part, and a temperature sensing module. and LED indicators. Among them, the battery provides electrical energy for the motor, and this process converts the electrical energy of the battery into the mechanical energy of the motor. The motor shaft is cylindrical, and the heating needle part is a cylindrical structure with a base. One end is closed and needle-shaped, which is the insertion end of the pod. The other end is open and has a large sheet base. The motor...
