Aerosol generation device with reduced preheating time
Provided herein is an aerosol generation device with a reduced preheating time. The aerosol generation device according to some embodiments of the present disclosure includes a case including an opening formed in one surface, and an article insertion portion into which an aerosol-generating article including an aerosol-generating substrate is inserted, an opening/closing type cover which is disposed on the one surface of the case to open and close the opening, and a heater configured to heat the inserted aerosol-generating article. Here, the opening/closing type cover is configured to, when closing the opening, mechanically press an aerosol-generating substrate portion of the inserted aerosol-generating article so that the entire aerosol-generating substrate portion is rapidly heated, and in this way, a preheating time of the device may be reduced.
1. An aerosol generation device comprising:
a case including an opening formed in one surface, and an article insertion portion into which an aerosol-generating article including an aerosol-generating substrate is to be inserted;
an opening/closing type cover disposed on the one surface of the case to open and close the opening, and configured to, when closing the opening, mechanically press an aerosol-generating substrate portion of the inserted aerosol-generating article; and
a heater configured to heat the inserted aerosol-generating article,
wherein the pressed aerosol-generating substrate portion comprises an upstream portion having a flat shape and a downstream portion having an inclined shape,
wherein the heater includes a first heater configured to heat one surface of the pressed aerosol-generating substrate portion and a second heater configured to heat the opposite surface of the one surface, and
wherein the opening/closing type cover is configured to, when closing the opening, mechanically press the aerosol-generating substrate portion of the inserted aerosol-generating article in a radius direction, the radius direction intersecting an axis in an insertion direction of the article insertion portion, so as to shorten the distance between a surface of the first heater where the one surface of the aerosol-generating substrate portion is heated and a surface of the second heater where the opposite side of the aerosol-generating substrate portion is heated.
2. The aerosol generation device of claim 1 , further comprising a controller configured to control the heater,
wherein the controller independently controls the first heater and the second heater.
3. The aerosol generation device of claim 1 , further comprising an extractor configured to push the inserted aerosol-generating article in a direction opposite to an insertion direction of the inserted aerosol-generating article.
4. The aerosol generation device of claim 3 , wherein the extractor is interlocked with the opening/closing type cover such that the extractor pushes the inserted aerosol-generating article as the opening/closing type cover opens the opening.
5. The aerosol generation device of claim 4 , wherein:
the opening/closing type cover opens the opening by rotary motion;
the opening/closing type cover is mechanically interlocked with the extractor by an interlocking member configured to convert the rotary motion of the opening/closing type cover to linear motion of the extractor; and
the extractor is configured to mechanically push the inserted aerosol-generating article by the linear motion.
6. The aerosol generation device of claim 1 , wherein:
the aerosol-generating article has a cylindrical shape; and
the opening/closing type cover presses the aerosol-generating substrate portion to have a diameter within a range of 10% to 50% of a diameter of the aerosol-generating article.
