The controller controls the metal heating net to energize and generate heat, and the heat is transferred to the tubular body 21, and then the tubular body 21 will Heat is transferred to the aerosol article 200 circumferentially.

The infrared electrothermal coating is used to receive electric power to generate heat, and then generate infrared rays of a certain wavelength, such as far infrared rays of 8 μm to 15 μm. When the wavelength of the infrared ray matches the absorption wavelength of the aerosol product 200 , the energy of the infrared ray is easily absorbed by the aerosol product 200 , thereby generating heat on the aerosol product 200 .

Or in some embodiments, as shown in FIG. 3 , the aerosol generating device 100 can also adopt electromagnetic or resistance central heating. Specifically, the heating assembly 20 is configured as an elongated shape with a needle-like sharp end, at least a part of the heating assembly 20 extends in the storage channel 50, and when the aerosol product 200 is stored in the storage channel 50, the heating The pointed end of the component 20 is inserted into the aerosol product 200 to be heated, thereby forming a central heating mode.

Alternatively, the heating element 20 may be made of conductive material, which can be passed through by a changing magnetic field to induce eddy currents, and then generate heat under the action of the eddy currents.

As shown in Fig. 2, Fig. 4 and Fig. 5, the aerosol generating device 100 also includes a flexible member 70, the flexible member 70 is made of soft rubber material which is elastic and easily deformed under extrusion force, and a suitable material can be It is silicone or rubber etc. The flexible part 70 is formed with a storage chamber 71, and the sensing element 80 is accommodated in the storage chamber 71, and the sensing element 80 is electrically connected to the controller. A cantilever 72 extends in the direction of 50 , and at least a part of the cantilever 72 protrudes into the receiving channel 50 . Therefore, when the aerosol product 200 is stored in the storage channel 50, the cantilever 72 is squeezed by the aerosol product 200, and the cantilever 72 moves away from the storage channel 50 under the action of the extrusion force, that is, moves away from the storage channel 50. The direction of the wall 711 is deformed, and then the wall 711 is driven to deform. Since the sensing element 80 is accommodated in the storage chamber 71, the sensing element 80 can sense the deformation of the wall 711 and generate an sensing signal, and send the sensing signal to the controller. After the controller receives the sensing signal, it can judge that the aerosol product 200 has been accommodated in the aerosol generating device 100 , thereby controlling the aerosol generating device 100 to start automatically, and the heating component 20 starts to heat the aerosol product 200 at this time.

Similarly, when the aerosol product 200 is removed from the aerosol generating device 100, the aerosol product 200 releases the extrusion of the cantilever 72, and the cantilever 72 moves toward the direction of the storage channel 50 under the action of the deformation restoring force, thereby making the The cantilever 72 releases the extrusion of the wall 711, and the wall 711 returns to the initial state under the action of the deformation restoring force, the sensing element 80 no longer senses the deformation of the wall 711, and the controller no longer obtains the sensing signal sent by the sensing element 80, and then When the controller determines that the aerosol product 200 has been removed from the aerosol generating device, the controller can control the aerosol generating device 100 to automatically shut down, and the heating component 20 stops heating at this time.

It should be noted that, in some other embodiments, the flexible member 70 may not be provided with the accommodation chamber 71, and the sensing element 80 may also be disposed adjacent to the cantilever 72, as long as the sensing element 80 can feel the deformation of the cantilever 72. Can.

In this embodiment, since the cantilever 72 is in a suspended state, it is only connected to the flexible member 70 in one direction, that is, the cantilever 72 is only connected to the wall 711 of the flexible member 70, and is connected to the flexible member 70 in other directions. 70 Not connected. Therefore, when the cantilever 72 is squeezed by the aerosol product 200, the cantilever 72 is more likely to deform, so that the cantilever 72 has a larger deformation amount, and the larger deformation of the cantilever 72 will trigger the sensing element 80 more easily, that is to say, the sensing element 80 The deformation of the cantilever 72 will be detected more sensitively, and then an induction signal will be generated and sent to the controller. However, the current convex hull is deformed because the convex hull is not suspended, and its surroundings are connected. Therefore, when the aerosol product 200 squeezes the convex hull, the convex hull is not easy to deform, or the deformation is very weak, and the sensing element is not easy to detect the convex hull. Deformation of the package, resulting in low detection sensitivity of the sensing element.

In some embodiments, the sensing element 80 is a pressure sensing element. When the cantilever 72 is squeezed and deformed, the cantilever 72 drives the wall 711 to deform, and the wall 711 deforms and transmits the deformation to the pressure sensing element, that is, the wall 711 A certain pressure is applied to the pressure sensing element through deformation, so that the change of pressure is sensed on the pressure sensing element, and the pressure sensing element converts the change of pressure into a sensing signal and sends it to the controller. The controller can judge according to the sensing signal The aerosol article 200 has been housed in the aerosol generating device. Or, in some embodiments, the sensing element 80 can also be a position sensing element, and there is a preset distance between the position sensing element and the wall 711 of the receiving chamber 71, and when the cantilever 72 is squeezed, the wall 711 is deformed, Thus, the wall 711 moves towards the direction close to the position sensing element. When it moves to a preset distance, the position sensing element is triggered and generates a sensing signal to send to the controller. The controller can judge that the aerosol product 200 has been accommodated according to the sensing signal. In the aerosol generating device, the automatic activation of the aerosol generating device is thereby controlled.

In some embodiments, as shown in FIG. 4 , the storage chamber 71 has a first side wall 712 and a second side wall 713 oppositely disposed, and the first side wall 712 and the second side wall 713 are distributed on both sides of the wall 711 That is to say, the wall 711 , the first side wall 712 and the second side wall 713 define the storage chamber 71 , and the first side wall 712 and the second side wall 713 also define the extension length of the storage chamber 71 in the transverse direction. The wall 711 maintains a certain gap 714 with the first side wall 712 and the second side wall 713, and the gap 714 reduces the rigidity of the wall 711, and when the cantilever 72 is squeezed, the wall 711 is easily deformed, and the wall 711 The deformation range will be larger, and thus trigger the sensing element 80 better. Furthermore, in some embodiments, the wall 711 is located in the middle between the first side wall 712 and the second side wall 713 , and this arrangement is favorable for triggering the sensing element 80 when the wall 711 is deformed.

As shown, d1 is the width of the cantilever 72, and d2 is the width of the wall 711. In this way, the connection area between the cantilever 72 and the wall 711 can be made sufficiently large, thereby improving the rigidity of the cantilever 72. When the cantilever 72 is squeezed by the aerosol product 200, the cantilever 20 is deformed in a direction away from the storage channel 50. During this time, the deformation of the wall 711 can be better driven, which is beneficial to the triggering of the sensing element 80 . If the width d1 of the cantilever 72 is too small, when the cantilever 72 is squeezed, the wall 711 cannot be well deformed, thereby affecting the triggering of the sensing element 80 .

In some embodiments, as shown in FIG. 7 , an inclined surface 721 is provided at the end of the cantilever 72 extending to the storage channel 50 , and the inclined surface 721 faces the through hole 111 , and on the one hand, when the aerosol product 200 enters the storage channel 50 , The aerosol product 200 abuts against the slope 721 of the cantilever 72, and the aerosol product 200 can continue to move smoothly toward the bottom of the storage channel 50 under the guidance of the slope 721; on the other hand, the aerosol product 200 can be applied through the slope 721. Give the cantilever 72 a force to move in the lateral direction, so that the cantilever 72 moves away from the receiving channel 50 to generate deformation, and then the cantilever 72 drives the wall 711 to deform.

In some embodiments, as shown in FIG. 7 , in order to smoothly drive the wall 711 to deform when the cantilever 72 is squeezed, the thickness d4 of the cantilever 72 is greater than the thickness d3 of the wall 711, that is, the rigidity of the cantilever 72 is greater than The rigidity of the wall 711 makes it easier for the wall 711 to deform under the pressing action of the cantilever 72 .

In some embodiments, as shown in FIG. 2 and FIG. 7 , the fixing frame 30 is provided with a buckle portion 31 , the flexible member 70 is provided with a slot 73 adapted to the buckle portion 31 , and the buckle portion 31 is fastened to card slot 73. Since the flexible piece 70 is made of soft rubber material, the buckle part 31 can be locked in the slot 73 by interference, so as to fix the flexible piece 70 in the aerosol generating device 100 . In this embodiment, in order to increase the engaging area between the buckle part 31 and the buckle groove 73, so that the flexible member 70 can be fixed more firmly, the buckle groove 73 and the buckle part 31 are both arc-shaped. The engaging groove 73 and the engaging portion 31 can increase the engagement area between the engaging portion 31 and the engaging groove 73 in a limited space. Certainly, in some other embodiments, the locking slot and the locking portion may not be arranged in an arc shape, for example, the flexible member 70 may also be firmly fixed by separately arranging a plurality of locking portions and locking slots to engage with each other. fixed.

In some embodiments, as shown in FIG. 4 , FIG. 5 and FIG. 7 , the aerosol generating device 100 further includes a connecting piece 90 connected to the flexible member 70, and the connecting piece 90 is formed with a through hole for the aerosol product 200 to pass through. 91 , the through hole 91 is not closed to form a gap 911 , through which the cantilever 72 protrudes into the receiving channel 50 .

In some embodiments, a rib 912 is formed around the inner wall of the through hole 91, and the rib 912 is used as a clamping part for clamping the aerosol product 200 when the aerosol product 200 passes through the through hole 91, so that the aerosol product 200 The sol product 200 is firmly stored in the storage channel 50 .
