HEATED SMOKING APPLIANCE CLAMPABLE AND SEALABLE Russian patent published in 2023 - IPC A24F40/40 A24F40/46 

FIELD: smoking devices.

SUBSTANCE: invention relates to the field of heated smoking devices, and in particular, it relates to a heated smoking device that can be clamped and sealed. The effect is achieved in that the heated smoking device is made with the possibility of clamping and ensuring tightness, characterized in that the specified heated smoking device contains an annular movable clamping means; said movable clamping means comprises: a movable swivel ring and associated sliding wheels, a plurality of clamping elements; wherein each of these clamping elements is provided with an axis of rotation and a groove for sliding; said movable swivel ring comprises an annular structure whose radius of the central hole of the annular structure is R; these clamping elements are arcuate elements of the ring, while the radius of the inner circumference of the ring is R; each of said sliding wheels is rigidly mounted on an end surface inside said movable rotary ring; each of said clamping elements is also fixed on the end surface by means of the axis of rotation inside the movable swivel ring; said axes of rotation are located on said clamping elements at a point closer to the center of the circle on which the arcuate elements are located; each of the sliding wheels is slidably connected, respectively, to one of said clamping elements located in the corresponding position; each of the sliding wheels with the possibility of rolling or sliding is limited in one of the specified grooves for sliding; turning said movable swivel ring moves each of said sliding wheels; each of the specified sliding wheels through the specified groove for sliding ensures the rotation of one of the specified clamping elements with the movement of the specified clamping elements relative to the center of the inner circle.

EFFECT: when using a heated smoking device in combination with a low oxygen heated cigarette, the movable clamping means will seal said sealed heating chamber tightly and clamp the cigarette so that ambient oxygen does not enter said sealed containing chamber and, during smoking, the oxygen content in the tobacco part will decrease, while the heating temperature of the cigarette may increase, but without the possibility of combustion of the cigarette, and the release of tobacco flavor components may increase.
