To further illustrate the disclosure, embodiments detailing a heated tobacco product are described below. It should be noted that the following embodiments are intended to describe and not to limit the disclosure.
As shown in FIGS. 1-4, a heated tobacco product comprises a main body 2 and a fixing member. The main body 2 comprises a first chamber, and the fixing member is detachably disposed in the first chamber. The fixing member 1 comprises a second chamber 104 configured to hold a tobacco stick. One end of the second chamber 104 comprises a first opening 103 through which the tobacco stick is inserted into the second chamber 104. The fixing member 1 is detachably connected to the main body 2, which allows for rapid replacement of fixing members with different diameters and depths, which allows insertion of any kind of tobacco sticks into the heated tobacco product as well. The first chamber and the second chamber 104 can be of any shape without departing from the scope and spirit of the disclosure.
In certain examples, the fixing member 1 further comprises a first connector, and the first chamber comprises a second connector. The first connector is detachably connected to the second connector so as to secure the fixing member 1 in the first chamber. In certain examples, the first chamber is not provided with the second connector, which means that the fixing member 1 is detachably disposed in the first chamber through only the first connector. In certain examples, the fixing member 1 is not provided with the first connector, which means that the fixing member 1 is detachably disposed in the first chamber through only the second connector. Preferably, the first connector is detachably connected to the second connector to ensure that the fixing member 1 is disposed in the first chamber.
In certain examples, the first connector comprises a first thread, a first interference fit part, a first snap-fit part, a first magnetic member, a first adhesive, a first pluggable connector, or a combination thereof.

In certain examples, the second connector comprises a second thread, a second interference fit part, a second snap-fit part, a second magnetic member, a second adhesive, a second pluggable connector, or a combination thereof. Preferably, both the first connector and the second connector are magnets through which the fixing member 1 can be affixed to or detached from the main body 2. The attraction between the magnets allows for convenient replacement of fixing members 1 in various diameters and depths. The second thread is a helical structure. The second snap-fit part comprises a depression and a protrusion which can be deflected to catch the depression. The second magnetic member includes, but is not limited to, at least one piece of iron and at least one magnet. The second adhesive includes, but is not limited to, a hook and loop fastener. The second pluggable connector can be any shape, and comprises a slot and a plug which can be fitted into the slot.
In certain examples, the fixing member 1 further comprises a first tube 105 which is provided with a hollow space functioning as the second chamber 104.
In certain examples, one end of the fixing member 1 is recessed to form a first concave part 102 surrounded by a first bottom wall. The first opening 103 is disposed on the first bottom wall. The fixing member 1 further comprises a sliding member 101 slidable with respect to the first concave part 102. Another end of the fixing member 1 shrinks and extends axially to form a convex part 106. The first opening 103 extends through the convex part 106. The fixing member 1 further comprises a first tube 105 extending downward from the first bottom wall and communicating with the first opening. The first tube 105 is disposed through one end of the convex part 106 into the first opening 103. The first tube 105 is affixed to the first bottom wall using integral formation or other connection means. The first concave part 102 comprises an inner surface and a groove disposed on the inner surface. The sliding member 101 is movable in the groove. The sliding member 101 slides to one end of the first concave part 102 so as to allow the tobacco stick to be inserted through the first opening 103. The sliding member 101 slides to another end of the first concave part 102 so as to cover the first opening 103.
In certain examples, the first tube 105 comprises a distal end away from the first opening 103, and the distal end comprises a second bottom wall 107 comprising a through hole 108.
In certain examples, the main body 2 further comprises a second tube 204 and a heating element 206. The second tube 204 comprises a passage 203. One end of the second tube 204 comprises a second opening 202, and another end of the second tube 204 comprises a third bottom wall 205. The heating element 206 is disposed in the second tube 204 to heat the tobacco stick. The first tube 105 is matched with the second tube 204 in shape and size.
