Adjustable Heating Plate Mechanism for Compact Heat-Not-Burn Cigarettes

The patent extracts the heating function from a large heating chamber that heats the entire tobacco product, and concentrates it onto a small heating plate that directly contacts only the necessary portion of the cigarette body. This extraction reduces the volume of the heating chamber and the amount of air that needs to be heated, thereby reducing power consumption while maintaining the required atomization temperature.

Instead of uniformly heating the entire cigarette body through air convection in a large chamber, the patent applies heating locally at the contact point between the heating plate and the cigarette body. This localized heating approach concentrates thermal energy where it is most needed, improving heating efficiency and reducing overall power consumption.

The patent removes the unnecessary large heating chamber from the device structure and replaces it with a compact heating plate system. This extraction of the excessive heating volume allows the device to maintain effective heating temperature while significantly reducing the overall device volume and eliminating the need for larger batteries.

Instead of using a large chamber to heat tobacco indirectly through hot air, the patent inverts the approach by using a small heating surface to directly heat the tobacco locally. This inversion of the heating methodology achieves the same thermal effect with much smaller device volume.

The patent implements a locking mechanism that allows the bearing assembly to dynamically adjust its inner diameter, transforming the fixed heating plate structure into an adjustable one. This dynamic adjustment capability enables the device to accommodate cigarettes of different diameters while maintaining a relatively simple overall structure through the use of standardized mechanical components.

The patent changes the parameter of the bearing assembly's inner diameter from fixed to variable through the locking mechanism. By enabling the inner diameter parameter to be adjusted between different states, the heating plates can adapt to different cigarette diameters without requiring complete structural redesign.

The patent transforms the static bearing assembly into a dynamic one with adjustable inner diameter through the locking mechanism. This allows the bearing assembly to be manufactured with a standard base structure while gaining the capability to adapt to different cigarette sizes, maintaining manufacturing simplicity while improving versatility.

The patent makes the bearing assembly universal by enabling it to accommodate multiple cigarette diameters through the locking mechanism. The same bearing assembly structure can serve multiple functions by adjusting its inner diameter, eliminating the need for different bearing assemblies for different cigarette sizes.
