[0094] Based on the problems raised in the background technology, the present invention provides an aerosol generating device, such as Figure 1 Shown, including:

[0095] Heating assembly 20 is used to heat the solid medium to be heated, which is inserted into the heating chamber. Heating assembly 20 can be a module such as a resistance wire or silk-screened resistance circuit that generates heat when energized, thereby heating the solid medium. Heating assembly 20 can also comprise metal tubing, which generates heat by inducing eddy currents in an alternating magnetic field. The solid medium to be heated can include leafy solids such as spices and herbs, as well as high-temperature-resistant tubes containing essences.

[0096] Capacitor assembly 40, the capacitance of capacitor assembly 40 when a solid medium is inserted into the heating chamber is different from the initial capacitance when no solid medium is inserted into the heating chamber. Capacitor assembly 40 refers to a component that can form a capacitor. For example, capacitor assembly 40 can include two or more relatively insulated plates to form a capacitor. Capacitor assembly 40 can also be a unipolar plate to form a capacitor with other conductors such as a solid medium, that is, capacitor assembly 40 forms or cooperates with other conductors to form a capacitor device. The shape of its conductor can have a variety of options, for example, it can be rectangular, arched, annular or spiral, or a composite of these shapes. The conductor can also be one or more linear, nonlinear, planar or non-planar sections. The electrodes of the plates formed by the conductor can be flexible or electroplated. As long as the capacitor assembly 40 has a capacitance different from the capacitance when no solid medium is inserted into the heating chamber, it falls within the scope of protection of this application.

[0097] The control module 60 is electrically connected to the capacitor assembly 40 and the heating assembly 20, and is used to determine whether a solid medium has been inserted into the heating chamber based on the capacitance of the capacitor assembly 40, and to control the heating assembly 20 to perform a heating operation if it is determined that a solid medium has been inserted into the heating chamber. Due to the shape characteristics of the capacitor assembly 40, the change in the capacitance of the capacitor assembly 40 during the process of inserting a solid medium into the heating chamber can be known and stored in advance. Based on this change in capacitance, the control module 60 can determine whether a solid medium has been inserted into the heating chamber based on the actual capacitance obtained from the capacitor assembly 40 during subsequent use of the aerosol generating device, and if it is determined that a solid medium has been inserted into the heating chamber, automatically control the heating assembly 20 to heat the solid medium.

[0098] Specifically, the aerosol generating device provides a capacitor component 40, the capacitance of which is transmitted to the control module 60 is different in two cases when a solid medium is inserted or not. By utilizing the calculation and control capabilities of the control module 60, it is determined whether the solid medium is inserted into the heating chamber based on the capacitance of the capacitor component 40, and when it is determined that the solid medium is inserted into the heating chamber, the heating component 20 is controlled to perform a heating action, thereby realizing automatic startup of the aerosol generating device when a solid medium is inserted. There is no need to set hardware modules such as buttons, and the heating startup is quick and convenient.

[0099] In one embodiment, Figure 2-3As shown, the capacitor assembly 40 includes: at least two oppositely arranged plates 42; each two oppositely arranged plates 42 are respectively arranged on both sides of the solid dielectric insertion direction, and the relative area is not zero, as shown in FIG. Figure 4-5 As shown, one of the plates 42 is grounded or connected to a first input terminal of the control module 60 , and the other plate 42 is connected to a second input terminal of the control module 60 .

[0100] Here, the relative arrangement means that the relative area between the two plates 42 is not zero, and a capacitor can be formed. The relative area is not zero, which means that one plate 42 at least partially overlaps the other plate 42 when projected onto the other plate 42. In the case where the plates 42 are arranged relative to form a capacitor, since every two plates 42 arranged relative to each other can form a capacitor, for such a capacitor component 40, Figure 4 As shown, it is only necessary to connect one of the plates 42 in each pair to the ground and the other to the second input terminal of the control module 60 to realize the acquisition of the capacitance of the capacitor assembly 40. By adding the two plates 42, the control module 60 acquires the capacitance of the capacitor assembly 40. In addition, it is also possible to Figure 5 As shown, one of the plates 42 in each pair can be connected to the first input terminal of the control module 60 , and the other can be connected to the second input terminal of the control module 60 to collect the capacitance of the capacitor assembly 40 .

[0101] The above-mentioned electrode plates 42 are arranged on the cavity wall of the heating chamber 90. For example, they can be arranged on the outer surface or inner surface of the side cavity wall or at least partially embedded in the side cavity wall (a part of the side cavity wall or the side cavity wall itself). At this time, when no solid medium is inserted into the heating chamber 90, the medium between the two oppositely arranged electrode plates 42 is air, and the two electrode plates 42 have an initial capacitance. When a solid medium is inserted into the heating chamber 90, including the insertion process of the solid medium and the situation where it is fully inserted into the heating chamber 90, based on the principle of capacitance between the electrode plates 42, it can be known that when a solid medium such as a dielectric or metal oxide is inserted between the electrode plates 42, the capacitance between the electrode plates 42 increases compared to when the medium between the electrode plates 42 is air. In addition, the size of the capacitance is also related to the distance between the electrode plates 42. If the distance between each pair of electrode plates 42 gradually increases or decreases along the insertion direction of the solid medium, the corresponding capacitance between the electrode plates 42 will also gradually decrease or increase with the insertion of the solid medium. In addition, during the process of pulling out the solid medium from the heating chamber 90, the capacitance between the corresponding pair of plates 42 increases or decreases gradually as the solid medium is pulled out. Figure 3As shown, multiple pole plates 42 are arranged on both sides of the insertion direction of the solid medium, for example, one pole plate 42 corresponds to two pole plates 42, and the two pole plates 42 on the same side are arranged at intervals in the insertion direction of the solid medium, so that the precise position of the solid medium during the insertion / extraction process can be accurately monitored during the insertion and extraction process of the solid medium.

[0102] In summary, the control module 60 can determine whether a solid medium is inserted / removed by collecting the change in the capacitance of the capacitor component 40, and can accurately identify whether the solid medium is in the inserted state, removed state, inserted state, removed state, and removed state.

[0103] Specifically, in one embodiment, the control module 60 can determine the operating state of the solid dielectric based on the capacitance of the capacitor assembly 40: inserted state, removed state, inserted state, removed state, removed state, or removed state. Based on the operating state identified by the control module 60, the prompt device can be controlled to provide a corresponding prompt. For example, if the prompt device is an indicator light, the indicator light will display different colors under different operating states. If the prompt device is a voice module, the control module 60 will drive the voice module to issue a corresponding prompt based on the determined operating state.

[0104] In one embodiment, Figure 9 As shown, when the substrate 80 forming the heating chamber 90 is a conductor, the heating assembly 20 includes the substrate 80, which can serve as the plate 42 of the capacitor assembly 40 and can also be heated. The plate 42 is the side wall of the substrate 80 forming the heating chamber 90, for example, Figure 9 As shown, the capacitor assembly 40 includes symmetrically arranged side walls of the base 80; or, as shown Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, when the substrate 80 forming the heating chamber 90 is non-conductive, the electrode plate 42 is a conductor disposed on the sidewall of the substrate 80. Disposing on the sidewall of the substrate 80 includes disposing on the inner surface or outer surface of the sidewall, or partially embedded in the sidewall. Therefore, those skilled in the art will understand that when the substrate 80 is conductive, it can be part of the capacitor assembly 40 or part of the heating assembly 20.

[0105] Considering that the solid medium 10 itself can also serve as a plate 42, when the solid medium 10 enters the heating chamber 90, the solid medium 10 can form a capacitor with any plate 42. Therefore, in one embodiment, as shown in FIG. Figure 10-11 As shown, when the solid medium 10 acts as a plate 42 (it should be emphasized that the shape of the plate 42 is not limited and can be as follows Figure 13The shape shown is a curved surface or a rectangular shape, as long as it can form an insulating relationship with the other electrode 42 and has a certain relative area. For example, the solid dielectric 10 can be a cylindrical dielectric. When the capacitor component 40 includes:

[0106] At least one electrode plate 42, when the solid medium 10 is inserted into the heating chamber 90, as shown Figure 10-12 As shown, the plate 42 and the solid medium 10 form a capacitor (the solid medium 10 can be understood as a part of the capacitor component 40); Figure 14 As shown, the first input end of the control module 60 is electrically connected to the solid medium 10 when the solid medium 10 is inserted into the heating chamber 90, and the second input end of the control module 60 is electrically connected to each electrode 42. By loading voltage on the two electrodes 42, the capacitance of the electrode 42 and the solid medium 10 is collected and used as the capacitance of the capacitor component 40, and then it is determined whether the solid medium 10 is inserted into the heating chamber 90. When it is determined that a medium is inserted, the heating component 20 is controlled to automatically heat.

[0107] It should be noted that the electrical connection between the first input terminal of the control module 60 and the solid medium 10 when the solid medium 10 is inserted into the heating chamber 90 is not limited to this case. For an aerosol generating device such as an aromatherapy machine, when the solid medium 10 containing essential oil is not inserted into the heating chamber 90, one end of the solid medium 10 can also be connected to the control module 60 via an elastic wire and placed in a storage position on the outer wall of the aerosol generating device. When heating is required, the user can insert the solid medium 10 into the heating chamber 90. At this time, the control module 60 determines that the solid medium 10 is inserted into the heating chamber 90 based on the change in the capacitance of the capacitor component 40, controls the heating component 20 to heat, and heats the essential oil in the solid medium 10, thereby realizing intelligent heating.

[0108] In one embodiment, Figure 10-11 As shown, when the substrate 80 forming the heating chamber 90 is a conductor and the number of the electrode plates 42 is equal to one, the heating assembly 20 includes the substrate 80, and the electrode plates 42 are the side walls or bottom walls of the substrate 80 forming the heating chamber 90; or, as shown Figure 6-7 When the substrate 80 forming the heating chamber 90 is non-conductive and the number of the electrode plate 42 is equal to one, the electrode plate 42 is a conductor disposed on the side wall or bottom wall of the substrate 80; or Figure 12 As shown, when the substrate 80 forming the heating chamber 90 is a conductor and the number of the electrode plates 42 is equal to two, the heating assembly 20 includes the substrate 80, and the electrode plates 42 are the side walls and bottom walls of the substrate 80 forming the heating chamber 90; or, as shown Figure 8 As shown, when the substrate 80 forming the heating chamber 90 is a non-conductor and the number of the electrode plates 42 is equal to two, the electrode plates 42 are conductors disposed on the side walls and the bottom wall of the substrate 80 .

[0109] In one embodiment, Figure 13 and Figure 15 As shown, the plate spacing and / or relative area of the plates 42 with non-zero relative areas on both sides of the solid medium 10 in the insertion direction change according to a preset rule along the insertion direction of the solid medium 10. When the shape and plate spacing of the plates 42 are constant, for the same solid medium 10, during the insertion process of the solid medium 10 into the heating chamber 90, the change in the size of the capacitance formed by the two plates 42 with non-zero relative areas is constant. A test can be conducted in advance to obtain a curve of the capacitance change during the insertion and removal of the solid medium 10 in the aerosol generating device with the plate spacing and / or relative area between the plates changing according to the preset rule. The capacitance change curve during the insertion process and the capacitance change curve during the removal process can be obtained. The control module 60 can pre-store the curve. When the aerosol generating device is subsequently used, the control module 60 collects the capacitance of the capacitor component 40. If the capacitance change of the capacitor component 40 is consistent or substantially consistent with the pre-stored capacitance change curve during the insertion process (i.e., matching), the control module 60 can determine that the solid medium 10 has been inserted into the heating chamber 90. If the capacitance change of the capacitor assembly 40 is consistent or substantially consistent with (ie, matches) the pre-stored capacitance change curve of the removal process, the control module 60 may determine that the solid medium 10 is removed from the heating chamber 90 .

[0110] Of course, a point can be marked on the capacitance change curve during the insertion process, and the capacitance value corresponding to this point can be used as a first preset threshold. When the control module 60 detects that the capacitance of the capacitor assembly 40 is greater than the first preset threshold, it indicates that the solid medium 10 has been mostly inserted into the heating chamber 90. At this time, the control module 60 can determine that the solid state is the insertion state and control the heating assembly 20 to heat. This can eliminate false detection caused by the solid medium 10 passing through the opening of the heating chamber 90.

[0111] Similarly, a point on the capacitance change curve of the unplugging process can be marked, and the capacitance value corresponding to the point can be used as the second preset threshold. When the control module 60 determines that a solid medium 10 has entered the heating chamber 90, if the capacitance of the capacitor component 40 is monitored to be less than the second preset threshold, it means that the solid medium 10 has been basically completely unplugged. At this time, the control module 60 determines that the action state is the unplugging state, and controls the heating component 20 to stop heating. This setting can avoid abnormal heating stop caused by the shaking of the solid medium 10 in the heating chamber 90.

[0112] In one embodiment, Figure 13 and 15As shown, the preset rule is to gradually increase or gradually decrease. The aerosol generating device provided in the embodiment of the present application realizes the action of judging the gradual insertion of the solid medium 10 by changing the spacing between the plates 42. For example, in order to facilitate the user to quickly insert the solid medium 10, the spacing between the plates 42 at the entrance of the heating chamber 90 can be configured to be larger and / or the relative area between the plates at the entrance can be configured to be smaller, and the spacing between the plates 42 near the bottom of the heating chamber 90 can be configured to be smaller and / or the relative area can be configured to be larger. In this case, as the solid medium 10 is inserted, the capacitance of the capacitor component 40 changes from small to large, and a first preset threshold value can be selected within the range of its capacitance change as a basis for judging that the solid medium 10 has been inserted into the heating chamber 90. When the control module 60 detects that the capacitance of the capacitor component 40 is greater than the first preset threshold value, it is determined that the solid medium 10 is inserted into the heating chamber 90, and the control module 60 controls the heating component 20 to work.

[0113] In one embodiment, Figure 1 、 Figure 4 、 Figure 5 and Figure 14 As shown, the control module 60 includes:

[0114] A signal acquisition module 62, whose input end is connected to the capacitor component 40, is used to convert the capacitance of the capacitor component 40 into a target electrical signal;

[0115] The processing module 64 has an input end connected to the output end of the signal acquisition module 62, and an output end connected to the heating component 20. It is used to determine whether a solid medium 10 is inserted into the heating chamber 90 based on the target electrical signal, and control the heating component 20 to perform a heating action when it is determined that a solid medium 10 is inserted into the heating chamber 90.

[0116] The target electrical signal refers to a signal that matches the protocol of the input port of the processing module 64. For example, it can be an electrical signal such as voltage, current, resistance, frequency, phase, etc., which can be used to characterize the capacitance of the capacitor assembly 40. The signal acquisition module 62 refers to a module with signal input and output functions. In addition, the signal acquisition module 62 can also perform other processing such as analog-to-digital conversion. The processing module 64 refers to a module that can perform signal processing and issue control signals to control the operating state of the heating assembly 20. For example, the processing module 64 may include other peripheral devices such as a processing chip and a filter.

[0117] The capacitance acquisition of the control module 60 in the above embodiment can be realized by the signal acquisition module 62 here. The control module 60 determines whether the solid medium 10 is inserted or removed and controls the heating component 20 to heat or prohibits the heating component 20 from heating. The connection relationship between the above signal acquisition module 62 and the capacitor component 40 can be seen in the two cases where the solid medium 10 serves as one of the plates 42 of the capacitor component 40 or not. Figure 4 、 Figure 5 and Figure 14 As shown, no further details are given here.

[0118] To ensure that the capacitance variation of the capacitor component 40 to be tested is within an ideal variation range, in one embodiment, as shown in FIG. Figure 16 and Figure 17 As shown, the aerosol generating device also includes:

[0119] At least one first capacitor 30, the first capacitor 30 is connected in series to the connection loop between the capacitor component 40 and the control module 60;

[0120] and / or, at least one second capacitor 50 , the second capacitor 50 being connected in parallel with the capacitor component 40 .

[0121] By selecting appropriate first capacitor 30 and second capacitor 50 , the capacitance variation range of capacitor assembly 40 is controlled within an appropriate range, thereby improving the detection accuracy and sensitivity of processing module 64 .

[0122] In one embodiment, the control module 60 is further used to prohibit the heating component 20 from performing a heating action when it is determined that no solid medium 10 is inserted into the heating chamber 90 or when it is determined that a solid medium 10 is inserted into the heating chamber 90 and it is determined that a solid medium 10 is pulled out of the heating chamber 90 based on the capacitance of the capacitor component 40.

[0123] As described in the above embodiments and the following method embodiments, in order to prevent the aerosol generating device from heating when no solid medium 10 is inserted, when the control module 60 determines that the solid medium 10 is pulled out of the heating chamber 90, protection can be provided by prohibiting the heating component 20 from performing the heating action, thereby increasing the service life of the device.

[0124] In a second aspect, the present application also provides a heating control method, such as Figure 18 As shown, applied to an aerosol generating device, the method includes:

[0125] S20: obtaining a capacitance output by the capacitor assembly, wherein the capacitance of the capacitor assembly when a solid medium is inserted into the heating chamber is different from the initial capacitance when no solid medium is inserted into the heating chamber;

[0126] S40: determining whether a solid dielectric is inserted into the heating chamber according to the capacitance of the capacitor assembly;

[0127] S60: When it is determined that a solid medium is inserted into the heating chamber, the heating component is controlled to perform a heating action; the heating component is used to heat the solid medium to be heated inserted into the heating chamber.

[0128] In one embodiment, Figure 13 and Figure 15 As shown, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero change according to a preset rule along the solid medium insertion direction;

[0129] The preset rule is that when the distance between the plates gradually decreases and / or the relative area gradually increases, Figure 19 As shown, step S40 of determining whether a solid medium is inserted into the heating chamber according to the capacitance of the capacitor assembly includes:

[0130] S42: If it is monitored that the capacitance of the capacitor assembly is greater than a first preset threshold, it is determined that a solid medium is inserted into the heating chamber.

[0131] Among them, when the capacitor components such as Figure 13 As shown in (e), when the plate spacing and relative area remain consistent along the insertion direction, due to the plate capacitance characteristics, the capacitance when a solid medium is inserted is greater than the initial capacitance when no solid medium is inserted, so the initial capacitance can be set as the first preset threshold. In addition, as described in the above embodiments, for an aerosol generating device in which the plate spacing decreases from large to small or the relative area increases from small to large along the direction of solid medium insertion, the capacitance of the capacitor component increases from small to large during the solid medium insertion process. A capacitance value is selected within this capacitance variation range and used as the first preset threshold value as the basis for determining whether a solid medium has been inserted into the heating chamber.

[0132] In one embodiment, Figure 13 and Figure 15 As shown, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero change according to a preset rule along the solid medium insertion direction;

[0133] The preset rule is that when the distance between the plates gradually increases and / or the relative area gradually decreases, it can avoid the shaking of the solid medium caused by the inlet of the heating chamber being too large, such as Figure 19 As shown, step S40 of determining whether a solid medium is inserted into the heating chamber according to the capacitance of the capacitor assembly includes:

[0134] If it is monitored that the capacitance of the capacitor component is less than the first preset threshold, it is determined that a solid medium is inserted into the heating chamber.

[0135] In one embodiment, Figure 13 and 15 As shown, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero change according to a preset rule along the solid medium insertion direction;

[0136] like Figure 19 As shown, step S40 of determining whether a solid medium is inserted into the heating chamber according to the capacitance of the capacitor assembly includes:

[0137] S44: Determine whether a solid medium is inserted into the heating chamber based on the change in capacitance of the capacitor assembly and a preset rule.

[0138] As described in the above embodiment, in addition to judging whether a solid medium is inserted / removed based on a threshold value, it can also be judged based on whether the capacitance change curve of the capacitor component during the insertion / removal of the solid medium matches the capacitance change of the capacitor component actually monitored by the control module when the plate shape is determined.

[0139] The preset rules characterize the changes in the plate spacing and relative area of the capacitor assembly plates, and based on the changes, the changes in the capacitance of the capacitor assembly can be determined. Therefore, it can be determined whether a solid medium is inserted / pulled out of the heating chamber based on the changes in the capacitance of the capacitor assembly and the preset rules.

[0140] In one embodiment, the preset rule is that the distance between the plates gradually increases and / or the relative area gradually decreases. Based on the change in the capacitance of the capacitor assembly and the preset rule, step S44 of determining whether a solid medium is inserted into the heating chamber includes:

[0141] If it is monitored that the capacitance of the capacitor component gradually decreases, it is determined that a solid medium is inserted into the heating chamber;

[0142] Alternatively, the preset rule is that the plate spacing gradually decreases and / or the relative area gradually increases. According to the change in the capacitance of the capacitor assembly and the preset rule, step S44 of determining whether a solid medium is inserted into the heating chamber includes:

[0143] If it is monitored that the capacitance of the capacitor component is gradually increasing, it is determined that a solid medium is inserted into the heating chamber.

[0144] Based on the characteristic that capacitance decreases with the increase of plate spacing and increases with the increase of relative area, the above-mentioned method steps can be executed to realize the identification and judgment of the solid medium inserted into the heating chamber, and when it is determined that the solid medium is inserted into the heating chamber, the heating component is controlled to perform the heating action.

[0145] To avoid accidental heating of the aerosol generating device when there is no solid medium, in one embodiment, as Figure 20 As shown, the above method also includes:

[0146] S50: If it is determined that a solid medium is inserted into the heating chamber, determining whether the solid medium is removed from the heating chamber based on the capacitance of the capacitor assembly;

[0147] S70: If it is determined that the solid medium is pulled out of the heating chamber or it is determined that no solid medium is inserted into the heating chamber, the heating component is controlled to stop working.

[0148] By monitoring the capacitance change of the capacitor assembly, it is determined whether the solid dielectric has been removed. The specific implementation can refer to the above process for determining the insertion of the solid dielectric. Since the insertion and removal actions are opposite, the removal of the solid dielectric can also be determined based on the opposite logic.

[0149] In one embodiment, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero changes according to a preset rule along the solid medium insertion direction;

[0150] The preset rule is that the distance between the plates gradually decreases and / or the relative area gradually increases. When it is determined that a solid medium is inserted into the heating chamber, step S50 of determining whether the solid medium is removed from the heating chamber based on the capacitance of the capacitor assembly includes:

[0151] If it is monitored that the capacitance of the capacitor component is less than or equal to the second preset threshold, it is determined that the solid medium is pulled out of the heating chamber.

[0152] The second preset threshold value can be set to a capacitance value within a range of capacitance variation of the capacitor component during the process of removing the solid dielectric. In one embodiment, the second preset threshold value and the first preset threshold value can be set to the same capacitance value.

[0153] like Figure 13 In the case of the plate setting shown in (e), when the plate spacing and relative area do not change along the insertion direction, the second preset threshold can be set to the initial capacitance. When the capacitance of the capacitor assembly is monitored to be equal to the second preset threshold, it is determined that a solid medium has been pulled out of the heating chamber.

[0154] In one embodiment, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero changes according to a preset rule along the solid medium insertion direction;

[0155] The preset rule is that the distance between the plates gradually increases and / or the relative area gradually decreases. When it is determined that a solid medium is inserted into the heating chamber, step S50 of determining whether the solid medium is removed from the heating chamber based on the capacitance of the capacitor assembly includes:

[0156] If it is monitored that the capacitance of the capacitor component is greater than a second preset threshold, it is determined that the solid medium is pulled out of the heating chamber.

[0157] In one embodiment, the plate spacing and / or relative area of the plates whose relative areas on both sides of the solid medium insertion direction are not zero changes according to a preset rule along the solid medium insertion direction;

[0158] In the case where it is determined that a solid medium is inserted into the heating chamber, step S50 of determining whether the solid medium is removed from the heating chamber based on the capacitance of the capacitor assembly includes:

[0159] When it is determined that a solid medium is inserted into the heating chamber, it is determined whether the solid medium is removed from the heating chamber according to a change in the capacitance of the capacitor assembly and a preset rule.

[0160] In one embodiment, the preset rule is that the distance between the plates gradually increases and / or the relative area gradually decreases. When it is determined that a solid medium is inserted into the heating chamber, the step of determining whether the solid medium is removed from the heating chamber based on the change in capacitance of the capacitor assembly and the preset rule includes:

[0161] In the case where it is determined that a solid medium is inserted into the heating chamber, if it is monitored that the capacitance of the capacitor assembly gradually increases, it is determined that the solid medium is pulled out of the heating chamber;

[0162] Alternatively, the preset rule is that the distance between the plates gradually decreases and / or the relative area gradually increases. When it is determined that a solid medium is inserted into the heating chamber, the step of determining whether the solid medium is removed from the heating chamber based on the change in capacitance of the capacitor assembly and the preset rule includes:

[0163] If it is monitored that the capacitance of the capacitor component is gradually decreasing, it is determined that the solid medium is being pulled out of the heating chamber.

[0164] In one embodiment, the method further includes:

[0165] Periodically obtaining the capacitance of the capacitor assembly when the solid medium is not inserted into the heating chamber and / or periodically obtaining the capacitance of the capacitor assembly when the solid medium is not inserted into the heating chamber;

[0166] The first preset threshold and / or the second preset threshold are updated according to the periodically acquired capacitance.

[0167] By regularly obtaining and updating the initial capacitance and the capacitance when a solid medium is inserted, the first preset threshold and the second preset threshold can be dynamically updated. This ensures that as the aerosol generating device is used, even in the event of deformation or corrosion of the plates forming the capacitor, accurate detection of the insertion / removal of the solid medium can still be guaranteed, achieving intelligent start-up when inserted and heating prohibition protection when there is no solid medium, thereby improving working reliability.

By implementing the aforementioned heating control method, on the one hand, intelligent activation of the aerosol generating device can be achieved when a solid medium is inserted, and on the other hand, damage to the device caused by malfunction of the heating component when no solid medium is inserted can be prevented.
