Specifically, the heating body 21 can be needle-shaped, sheet-shaped, cone-shaped and other shapes that can be inserted into the heating cavity 3; the cigarette can be tobacco, smoke oil or other smoking materials; the electrical system includes a truncated cone-shaped base. 22. The power supply and control components are arranged inside the base 22. The heating body 21 is fixed at the end of the base 22 and is connected to the internal control components of the electrical system. The temperature change of the heating body 21 can be changed by changing the output power of the electrical system. , to adjust the heating temperature of the cigarette to ensure that the aroma components in the cigarette are fully volatilized. Since the heating device of the smoking set is an existing technology, its internal structure and specific implementation will not be described in detail here.

In this embodiment, as shown in Figure 3, one end of the inner housing 11 is fixedly connected to the base 22 of the heating device, and the other end is provided with a flange. The flange is provided with a slideway, and the outer housing 12 passes through the flange. The slideway is rotatably connected to the inner housing 11 so that the outer housing 12 can rotate around the axis of the inner housing 11. At the same time, the flange can cover the upper port of the accommodation cavity 4 to prevent dust and impurities from falling into the accommodation cavity 4. The sealing property and heat insulation effect of the accommodation cavity 4 are improved.

In this embodiment, as shown in Figures 2-8, the inner housing 11 is also provided with an adjustment hole 112 penetrating the cylinder wall of the inner housing 11, and a slide rail 111 provided on the outer wall of the inner housing 11; cigarette holder The tightening device includes a clamping piece 5 that extends into the heating cavity 3 through the adjustment hole 112, and a transmission assembly 6 that drives the clamping piece 5 to move; the transmission assembly 6 includes one end inserted into the inside of the slide rail 111, and the other end is fixedly connected to the outer shell 12 The first transmission rod 61, the second transmission rod 62 connected to the clamping piece 5, and the elastic element 63 connecting the first transmission rod 61 and the second transmission rod 62 enable the outer shell 12 to rotate relative to the inner shell 11. The clamping piece 5 is driven to clamp the cigarette to prevent the cigarette from being taken out of the heating chamber 3 due to too small friction between the cigarette and the inner shell 11 when smoking. Specifically, the first transmission rod 61 is cylindrical, and one end inserted into the slide rail 111 has a smooth surface and is provided with rounded corners to reduce friction, so that the first transmission rod 61 can slide back and forth along the extension direction of the slide rail 111; the second The transmission rod 62 is a square thin plate, made of plastic or metal, and is arranged along the axis direction of the inner housing 11. One end is a free end, and the other end is rotationally connected to the elastic element 63. The clamping piece 5 is located on the second transmission rod 62. The two ends are fixedly connected to the second transmission rod 62 through screws or rivets, so that the second transmission rod 62 can be suspended in the accommodation cavity 4 through the support of the clamping piece 5 or/and the elastic element 63; the elastic element 63 is made of metal shrapnel and is in the shape of an arc. The radius of the arc is greater than the radius of the inner housing 11. One end is fixedly connected to the first transmission rod 61, and the other end is rotationally connected to the end of the second transmission rod 62 close to the slide rail 111, and The connection point between the second transmission rod 62 and the elastic element 63 is located obliquely above the slide rail 111, so that the elastic element 63 is inclined. When the outer shell 12 is rotated, the fixed end of the elastic element 63 and the first transmission rod 61 follows. The outer shell 12 rotates and moves along the extending direction of the slide rail 111 . At this time, since the other end of the elastic element 63 is rotationally connected to the second transmission rod 62 and cannot produce displacement, the elastic element 63 will be stretched and at the same time produce an oblique downward pulling force on the second transmission rod 62, so that it is fixed on the second transmission rod 62. The clamping piece 5 on the transmission rod 62 contacts the adjustment hole 112 and deforms. Among them, the clamping piece 5 is U-shaped and is made of a metal elastic piece with good plasticity. It includes a hook portion 52 inserted into the adjustment hole 112 and a connecting portion 51 fixedly connected to the second transmission rod 62. The adjustment hole 112 is The edge is provided with a rounded corner 1121, and the hook 52 includes an arc surface 521 in contact with the edge of the adjustment hole 112. The radius of the arc surface 521 is greater than the radius of the round corner 1121, so that the arc surface 521 of the clamping piece 5 is in contact with the adjustment hole 112. The rounded corner 1121 surface is tangent, so that the clamping piece 5 can rotate to a certain extent around the rounded corner 1121 surface when it is stressed; when the clamping piece 5 is driven by the second transmission rod 62 to move downward and contacts the edge of the adjustment hole 112 When connected, the hook portion 52 will deform and extend toward the inside of the heating chamber 3 by taking the contact point with the adjustment hole 112 as a fulcrum, contacting the cigarette, and clamping the cigarette.

In this embodiment, as shown in FIG. 5 , a gap is provided between the connecting portion 51 of the clamping piece 5 and the outer surface of the inner shell 11 , so that the clamping piece 5 is clamped when rotating around the contact point with the adjustment hole 112 The connecting portion 51 of the piece 5 will not interfere with the inner shell 11 and provides space for the movement of the clamping piece 5 .

In this embodiment, the movement process of the cigarette clamping device is shown in Figure 5: In the initial state, as shown in Figure 5-a, the elastic element 63 is in its original length, and the clamping piece 5 is inserted through the adjustment hole 112 for heating. In the cavity 3, the arc surface 521 of the hook 52 abuts the rounded corner 1121 of the edge of the adjustment hole 112, so that the second transmission rod 62 is suspended in the accommodation cavity 4 through the clamping piece 5. At this time, the clamping piece 5 The part of the hook 52 inserted into the adjustment hole 112 fits the inner wall of the inner shell 11, which can prevent the cigarette from being scratched with the clamping piece 5 when the cigarette is inserted into the heating chamber 3, causing damage to the cigarette; when the cigarette is After inserting into the heating chamber 3, rotate the outer shell 12 in the clamping direction (that is, the elastic element 63 is stretched) to form a clamping state, as shown in Figure 5-b. Since the first transmission rod 61 is fixedly connected to the outer shell 12 , so the first transmission rod 61 will rotate together with the outer shell 12, and the end of the elastic element 63 fixedly connected to the first transmission rod 61 will move with the first transmission rod 61. At this time, because the other end of the elastic element 63 is connected with the first transmission rod 61, The two transmission rods 62 are rotationally connected and cannot be displaced, so the elastic element 63 is stretched. Since the elastic element 63 is arranged at an angle, it will produce an oblique downward pulling force on the second transmission rod 62, so that the clamping piece 5 is in contact with the adjustment The contact point of hole 112 is subject to downward pulling force. Since the clamping piece 5 is made of metal that can produce plastic deformation, the clamping piece 5 will warp toward the center of the heating chamber 3 with the contact point as a fulcrum after receiving force. An inclined plane is formed from the opening of the heating chamber 3 toward the bottom of the heating chamber 3, and is in contact with the cigarette to clamp the cigarette. As another implementation of this embodiment, as shown in Figure 6, the clamping piece 5 is a rigid piece and cannot produce plastic deformation. When the outer shell 12 is rotated to cause the elastic element 63 to be stretched, the clamping piece 5 is moved by the second The transmission rod 62 is driven to receive a downward pulling force. At this time, since the clamping piece 5 is rigid, the arc surface 521 of the hook 52 of the clamping piece 5 will rotate around the surface of the fillet 1121 of the adjustment hole 112, so that the clamping piece 5 is rigid. The hook portion 52 of the tightening piece 5 inserted into the heating chamber 3 is tilted and tilted from the opening of the heating chamber 3 toward the bottom of the heating chamber 3 to clamp the cigarette.

In this embodiment, as shown in FIG. 4 , the slide rail 111 is provided with a limiting protrusion 1111 for limiting the rotation range of the first transmission rod 61 . When the outer shell 12 is rotated, the first transmission rod 61 is driven in the slide rail 111 After moving beyond the limit protrusion 1111 and stopping the rotation, the limit protrusion 1111 can prevent the elastic element from shrinking and driving the first transmission rod 61 and the outer shell 12 to rotate, which affects the outer shell 12 and the first transmission rod in the clamped state. 61 for limit fixation.

In this embodiment, as shown in Figure 5, in order to make the force on the cigarette more uniform, the cigarette clamping device is provided with at least two groups, evenly distributed along the circumferential direction of the heating chamber 3, so that both sides of the circumference of the cigarette are clamped The clamping pieces 5 are in contact to prevent the cigarette from bending due to force on one side.

In this embodiment, as shown in FIG. 5 , in order to provide stability for clamping the cigarette, multiple adjustment holes 112 are provided along the axis direction of the inner housing 11 , and the clamping piece 5 is provided correspondingly to the adjustment holes 112 One end of several clamping pieces 5 is fixedly connected to the second transmission rod 62, and the other end is inserted into the heating cavity 3 through the adjustment hole 112, so that the cigarette can be stressed at multiple points in the length direction to prevent the cigarette from shaking.
