[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] See also Figure 1 , Figure 2 and Figure 3The embodiment of the present application provides an aerosol generating device, comprising: a main body 1, an extractor 2, a heating component 3, a controller 4, a power supply and a sensing component 6; the extractor 2 is relatively movably connected to the main body 1, and a heating chamber 21 is defined in the extractor 2, and the heating chamber 21 is used to accommodate at least a part of the aerosol generating product; at least a part of the heating component 3 is located in the heating chamber 21, and is used to heat the aerosol generating product; the controller 4 is electrically connected to the heating component 3; the power supply is used to supply power to the controller 4 and the heating component 3; at least a part of the sensing component 6 is arranged on the extractor 2, and the sensing component 6 is electrically connected to the controller 4; wherein the sensing component 6 is configured to detect the insertion or removal of the aerosol generating product, so as to start or stop the heating component 3 through the controller 4. By relatively movably connecting the extractor 2 to the main body 1, and arranging at least a part of the sensing component 6 on the extractor 2, the insertion or removal of the aerosol generating product can be detected by the sensing component 6, and the sensing component 6 is electrically connected to the controller 4, and the heating component 3 can be started or stopped by the controller 4 to heat the aerosol generating product. On the one hand, intelligent heating of the aerosol generating product can be realized, and on the other hand, the sensing component 6 can move relative to the main body 1 following the extractor 2, thereby facilitating the cleaning and maintenance of the sensing component 6.

[0039] Optionally, an aerosol-generating article refers to an article comprising an aerosol-generating substrate, which is intended to be heated rather than burned to release volatile compounds that can form an aerosol, and when heated, the aerosol-generating substrate releases volatile compounds that can form an aerosol. Compared to an aerosol generated by burning or pyrolytic degradation of an aerosol-forming substrate, the aerosol formed by heating the aerosol-forming substrate may contain fewer known harmful components. In one embodiment, the aerosol-generating article can be removed or connected to an aerosol-generating device. The aerosol-generating article can be disposable or reusable. The aerosol-forming substrate can be a solid aerosol-forming substrate. Alternatively, the aerosol-forming substrate can include solid and liquid components. The aerosol-forming substrate can include tobacco and / or non-tobacco materials; or the aerosol-forming substrate can include tobacco-containing materials and / or non-tobacco materials.

[0040] The extractor 2 is relatively movably connected to the main body 1, which means that the extractor 2 is detachably connected to the main body 1, so that the extractor 2 can be removed from the main body 1. The detachable connection between the extractor 2 and the main body 1 can be achieved in any way, such as by snap connection, magnetic connection, threaded connection, plug-in connection, or connection through fasteners. Exemplarily, magnetic parts can be respectively set at corresponding positions on the extractor 2 and the main body 1, and the extractor 2 and the main body 1 can be connected by magnetic attraction. When the extractor 2 is installed on the main body 1, the magnetic parts on the extractor 2 can be attracted to the magnetic parts on the main body 1, and the sensing component 6 can also be electrically connected to the controller 4, so that the insertion or removal of the aerosol generating product can be sensed, and the heating component 3 can be started or shut down. When the extractor 2 is removed from the main body 1, the sensing component 6 is electrically disconnected from the controller 4. In addition, the sensing component 6 is sensitive to changes in the external environment. For example, the long-term accumulation of aerosols generated during the heating process of the aerosol generating product or the aerosol generating matrix can easily cause the failure of the sensing component 6, thereby further causing the failure of the aerosol generating device. Therefore, when the extractor 2 is removed from the main body 1, the inner wall of the extractor 2 can be easily cleaned and maintained, thereby ensuring the normal operation of the sensing component 6 and increasing its lifespan.

[0041] In addition, the controller 4 may refer to a printed circuit board, which may be used to control functions of the aerosol generating device such as heating, power supply, temperature control, and lighting effects.

[0042] In some embodiments, see Figure 1 and Figure 2 At least a portion of the sensing component 6 may be disposed in or near the heating chamber 21. For example, a portion of the sensing component 6 may be disposed on the inner wall of the heating chamber 21, so that the sensing component 6 can better sense the insertion or removal of the aerosol generating article into or out of the heating chamber 21, thereby turning on or off the heating component 3. In some embodiments, see Figure 4 and Figure 5 The inner wall of the heating chamber 21 may be provided with a recessed portion 22, and the recessed portion 22 is used to accommodate at least a portion of the sensing component 6. Thus, the sensing component 6 can be installed inside the recessed portion 22 to prevent interference between the aerosol generating product and the sensing component 6 when the aerosol generating product is inserted into the heating chamber 21, thereby preventing damage to the aerosol generating product or the sensing component 6. Exemplarily, the recessed portion 22 can be configured as a rectangular slot, and a portion of the sensing component 6 can be installed in the rectangular slot. In some embodiments, see Figure 1 , Figure 5 and Figure 6, the sensing component 6 may include a sensor 61 and a wire 62, at least a portion of the sensor 61 may be disposed in the recessed portion 22; the sensor 61 is electrically connected to the controller 4 through the wire 62. When the extractor 2 and the main body 1 are in an installed state, the controller 4 is electrically connected to the sensing component 6 and can drive the sensing component 6 to work. When the sensor 61 senses that an aerosol generating product is inserted into the heating chamber 21, the signal is transmitted to the controller 4, and the heating component 3 in the aerosol generating device is started to start heating under the control of the controller 4, so that the aerosol generating product is heated to generate an aerosol for inhalation. When the aerosol generating product is removed from the heating chamber 21, the sensor 61 transmits the signal to the controller 4, so that the heating component 3 stops heating through the controller 4. In addition, the structure of the sensing component 6 is relatively simple, the recessed portion 22 only needs to accommodate the sensor 61, and the size of the recessed portion 22 can be set smaller, thereby reducing the difficulty of opening the recessed portion 22 on the inner wall of the extractor 2.

[0043] In some embodiments, see Figure 1 , Figure 5 and Figure 6 , a wire 62 wire 62 hole 23 may be provided in the extractor 2, the wire 62 wire 62 hole 23 may be used to accommodate at least a portion of the wire 62, and both ends of the wire 62 wire 62 hole 23 may be connected to the recessed portion 22 and the outside of the heating chamber 21 respectively. The extractor 2 may be surrounded by a side wall 26 and a bottom wall 27, and a wire 62 wire 62 hole 23 may be provided in the side wall 26 of the extractor 2. The wire 62 may be placed in the wire 62 wire 62 hole 23, one end of the wire 62 is connected to the sensor 61 in the recessed portion 22, and the other end is connected to the controller 4 provided outside the heating chamber 21. The provision of the wire 62 wire 62 hole 23 can protect the wire 62, and prevent the wire 62 from being damaged by interference with the aerosol generating product when the aerosol generating product is inserted into the heating chamber 21.

[0044] In some embodiments, see Figure 1 , Figure 5 and Figure 7The sensing component 6 may further include a sensing chip 63, which is used to drive the sensor 61 and transmit the electrical signal fed back by the sensor 61 to the controller 4. The sensing component 6 may be provided with a separate sensing chip 63, which may be disposed in the recessed portion 22, or in the wire 62 hole 23, or on the outside of the extractor 2, or integrated on the controller 4. The sensing chip 63 is electrically connected to the sensor 61, and the sensing chip 63 may be electrically connected to the power supply through the controller 4, or directly connected to the power supply through the wire 62. The sensing chip 63 may drive the sensor 61 to work, and transmit the electrical signal fed back by the sensor 61 to the controller 4, thereby starting or shutting down the heating component 3 through the controller 4. Exemplarily, the sensing chip 63 can be arranged outside the heating chamber 21 of the extractor 2 and directly electrically connected to the power supply through the wire 62, so that the sensor 61 can be started without passing through the controller 4, and the sensing chip 63 is spaced apart and electrically connected to the controller 4, so that the sensing chip 63 can transmit the electrical signal fed back by the sensor 61 to the controller 4, thereby controlling the heating component 3 through the controller 4.

[0045] In some embodiments, see Figure 1 , Figure 5 and Figure 7 At least a portion of the sensing chip 63 may be located in the recess 22. The sensing chip 63 may be disposed in the recess 22 together with the sensor 61, and the sensing chip 63 may be directly connected to the power supply and the controller 4 through the wire 62; or the sensing chip 63 may be electrically connected to the controller 4 through the wire 62.

[0046] In some embodiments, see Figure 1 , Figure 5 and Figure 8 The sensing component 6 may further include a battery 64, at least a portion of which may be disposed in the recessed portion 22, and the battery 64 is used to power the sensing chip 63 and the sensor 61. The sensing chip 63 and the sensor 61 are powered by the battery 64, so that the sensing chip 63 can transmit the electrical signal fed back by the sensor 61 to the controller 4, and the controller 4 can control the start or shut down of the heating component 3.

[0047] For example, see Figure 1 , Figure 5 and Figure 8, the controller 4 can be a printed circuit board, and the printed circuit board can have a control circuit of the heating component 3 built in. The sensor 61 can be a photoelectric sensor 61, and the photoelectric sensor 61 is arranged in the recessed portion 22 of the cigarette holder, and the sensing surface of the sensor 61 faces the heating chamber 21. The sensing chip 63 can also be arranged in the recessed portion 22 and connected to the sensor 61 through the wire 62. The sensing chip 63 can be built with a narrow-band filtering frequency selection processing module, which can process the photoelectric signal under the strong interference of external natural light. The battery 64 can be a button battery, which can also be arranged in the recessed portion 22 and connected to the sensing chip 63 through the wire 62. The output end of the sensing component 6 can be electrically connected to the controller 4 through the wire 62 (for example, the wire 62 can be electrically connected to the controller 4 through a pluggable electrode). The extractor 2 is combined with the main body 1 by magnetic attraction, and the button battery supplies power to the sensing chip 63. The sensing chip 63 starts to work, driving the output end of the sensor 61 to emit infrared or visible light. When the aerosol generating product is inserted into the heating chamber 21, the emitted infrared / visible light is reflected back to the receiving end of the sensor 61, processed and amplified by the sensing chip 63, and the electrical signal is output to the printed circuit board through the wire 62, so that the heating circuit controls the heating component 3 to start. After the suction is completed, the extractor 2 is lifted out of the main body 1, and the aerosol generating product can be removed from the extractor 2, the circuit between the sensing component 6 and the controller 4 is disconnected, and the heating component 3 stops heating. By setting the sensing component 6 in the recessed portion 22 on the side wall 26 of the extractor 2, the size of the aerosol generating product matched by the aerosol generating device does not need to be adjusted due to the setting of the sensing component, and the user's puffing taste and puffing experience remain unchanged; in addition, the extractor 2 is in a pluggable state. When the sensing surface of the sensor 61 in the sensing component 6 is contaminated, the extractor 2 can be removed from the main body 1, so that the sensor 61 on the recessed portion 22 can be easily cleaned and maintained.

[0048] Further, the sensor 61 in the sensing component 6 can be a through-beam photoelectric sensor 61, that is, a recess 22 can be respectively provided on the inner walls of the two sides of the heating chamber 21, a transmitting part of the through-beam photoelectric sensor 61 is provided in one recess 22, and a receiving part of the through-beam photoelectric sensor 61 is provided in the recess 22 on the other side, and both the transmitting part and the receiving part are electrically connected to the controller 4 through a wire 62, and when the aerosol generating product passes between the transmitting part and the receiving part, a control signal can be generated, and the controller 4 starts or shuts down the heating component 3 after receiving the control signal. Setting the sensor 61 in the sensing component 6 as a through-beam photoelectric sensor 61 can improve the accuracy of sensing.

[0049] In some other embodiments, see Figure 4, a convex strip 24 may be provided on the inner wall of the heating chamber 21. On the one hand, the convex strip 24 may play a guiding role when the aerosol generating product is inserted into the heating chamber 21, and a limiting role, so that the cooperation between the aerosol generating product and the heating component is more precise. On the other hand, due to the provision of the convex strip 24, a groove 29 may be constructed between the two convex strips 24, so that the sensing component 6 may be provided in the groove 29 between the convex strips 24, and the groove 29 may be a collection of the recessed portion 22 and the wire hole 23. Thus, the complicated process and difficulty of operating the recessed portion 22 and the wire hole 23 on the inner wall of the extractor 2 may be avoided, the sensor may be provided in the groove 29, and the wire 62 may also be provided along the groove 29 and electrically connected to the controller. Thus, the production efficiency of the extractor 2 may be improved, and the production cost of the extractor 2 may be reduced.

[0050] In some embodiments, see Figure 3 and Figure 5 The extractor 2 is provided with an insertion port 28, and the insertion port 28 is used for the aerosol generating product to pass through; a dust cover 25 is provided on the side of the insertion port 28 away from the heating component 3, and the dust cover 25 is connected to the extractor 2, and the dust cover 25 is configured to cover or expose the insertion port 28. The insertion port 28 is arranged opposite to the bottom wall 27, and the aerosol generating product can be inserted into the heating chamber 21 through the insertion port 28. On the one hand, the dust cover 25 can be opened or covered by moving the insertion port 28. When the insertion port 28 is opened, the aerosol generating product can be inserted into the heating chamber 21 through the insertion port 28, so as to start heating; when the insertion port 28 is covered by the dust cover 25, dust or other debris can be prevented from falling into the heating chamber 21. On the other hand, when the dust cover 25 opens the insertion port 28, the battery 64 can supply power to the sensing chip 63, thereby driving the sensor 61 to start working. When the dust cover 25 blocks the insertion port 28, the battery 64 can stop supplying power to the sensing chip 63; thus, the battery 64 can enter the working state only when the aerosol generating device is ready to use or in use, thereby saving the energy of the battery 64 and extending its life.

[0051] Optionally, the dust cover 25 and the extractor 2 can be integrally designed, and a sliding cover is provided on the dust cover 25, which can slide to open or cover the insertion port 28. The combined structure of the dust cover 25 and the extractor 2 can be connected to the main body 1 by magnetic attraction.

[0052] In some embodiments, see Figure 2 and Figure 3, the heating component 3 may include a heating needle 31, at least a portion of which is inserted into the heating chamber 21. The heating method of the aerosol generating device may be a central heating method, that is, the heating component 3 includes a heating needle 31, a portion of which is disposed inside the heating chamber 21, and when the aerosol generating product is inserted into the heating chamber 21 through the insertion port 28, a portion of the heating needle 31 may be inserted into the inside of the aerosol generating product, and the aerosol generating product is heated under the control of the controller 4. When the inhalation is finished, the extractor 2 may be pulled out to separate the extractor 2 from the main body 1, thereby separating the aerosol generating product from the heating needle 31, and then the aerosol generating product is removed.

[0053] In some embodiments, see Figure 3 The main body may include an extractor bracket 11 and a power supply bracket, and the extractor bracket 11 and the power supply bracket may be connected and fixed by fasteners. The extractor bracket 11 is configured with a receiving cavity, which can be used to receive a portion of the extractor 2. The extractor bracket 11 may be provided with a magnetic member, and the extractor 2 is detachably connected to the extractor bracket 11 by magnetic attraction. The power supply bracket is provided with a power supply slot, which can be used to receive a power supply. A connecting hole may be provided on the power supply bracket, and the controller 4 is electrically connected to the power supply through the connecting hole.

[0054] In some embodiments, see Figure 3 The main body also includes a shell 12, which is arranged outside the power supply bracket and the extractor bracket 11, and can be used to protect the internal components of the aerosol generating device, such as the extractor 2, the heating component 3, the controller 4, the power supply and the sensing component 6.

[0055] In other embodiments, a switch button is further provided on the housing 12 of the aerosol generating device, and the switch button is connected to a power source, and can be pressed to start the power source, thereby starting the heating component 3, and after heating is completed, the heating component 3 can be turned off by pressing again. The setting of the switch button can ensure the normal use of the aerosol generating product when the sensing component 6 fails.

[0056] It should be noted that the preferred embodiments of the present application are given in the specification and drawings of the present application, but are not limited to the embodiments described in the specification. Furthermore, it is possible for a person of ordinary skill in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present application.
