Aerosol generating device

[0001] Priority information

[0002] This application claims priority and benefits of patent application No. 202323605357.6 filed with the State Intellectual Property Office of China on December 27, 2023, and the entire text of which is incorporated herein by reference. Technical Field

[0003] The present application relates to the field of atomization technology, and more specifically, to an aerosol generating device. Background Art

[0004] An aerosol generating device is a small device that can heat an aerosol generating matrix and generate an aerosol by using a heat not burn (HNB) method. The shell of the aerosol generating device is provided with a cavity and a perforation, and the aerosol generating matrix can extend into the cavity through the perforation. In the related art, the aerosol generating device is provided with a shielding member that can block or open the perforation. After the aerosol generating matrix is ​​taken out from the cavity, the shielding member can block the perforation to prevent foreign matter from entering the cavity. Among them, since residues may remain in the cavity when the aerosol generating matrix is ​​taken out from the cavity, the user needs to clean the inside of the cavity to prevent the residues from affecting the installation of the aerosol generating matrix. However, the setting of the shielding member will affect the user's cleaning operation. For example, the user needs to apply force to the shielding member to open the perforation, which will result in a greater operational burden on the user and lower cleaning efficiency.

[0013] In some embodiments, the cover is rotatable relative to the body so that the cover opens the opening or aligns the opening with the through-hole.

[0014] In some embodiments, the moving component is rotatable relative to the cover body to switch between a state of blocking the through-hole and a state of opening the through-hole.

[0015] In some embodiments, the moving part includes a rotating shaft, a shielding member, a detected member and an elastic member. The rotating shaft is rotatably mounted on the cover body.

[0019] In certain embodiments, the detecting element is a Hall switch, the detected element is a magnetic element, and the Hall switch is used to detect the magnetic field of the magnetic element to determine whether the through hole is in an open state or a closed state.

[0020] In the aerosol generating device of the embodiment of the present application, the cover body can switch between a first state and a second state. When the cover body is in the second state, the detected part is beyond the detection range of the detection part. Therefore, the moving parts do not affect the user's cleaning operation, thereby facilitating the user to clean the heating chamber, reducing the user's operating burden and improving cleaning efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of such features. Throughout the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0041] In this application, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0042] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0043] Referring to Figures 1 and 2, the aerosol generating device 100 of the embodiment of the present application includes a main body 10, a cover 20 and a detection assembly 30. The main body 10 is provided with a heating chamber 11, which is used to accommodate an aerosol generating matrix 200. The cover 20 is provided with a through-hole 21 connected to the heating chamber 11, and the cover 20 can switch between a first state and a second state relative to the main body 10. The detection assembly 30 includes a moving part 31 and a detection member 33. The moving part 31 is provided on the cover 20 and can move relative to the cover 20 to be in a state of blocking the through-hole 21 or a state of opening the through-hole 21. The moving part 31 includes a detected member 315. When the cover 20 is in the first state, the cover 20 is connected to the main body 10, and the detection member 33 detects the state of the moving part 31 relative to the through-hole 21; when the cover 20 is in the second state, the detected member 315 exceeds the detection range of the detection member 33. It should be noted that, in some embodiments, the detection member 33 can detect the moving component 31 to confirm whether the aerosol generating substrate 200 is accommodated in the heating chamber 11 .

[0044] In some embodiments, the main body 10 includes a shell 15, and the aerosol generating device 100 may further include a power supply unit 50 and a heating component 60. The power supply unit 50 is electrically connected to the detection member 33 and the heating component 60, and is used to supply power to the detection member 33 and the heating component 60. The heating component 60 is electrically connected to the detection member 33, and when the detection member 33 confirms that the aerosol generating matrix 200 is accommodated in the heating chamber 11, the heating component 60 heats the aerosol generating matrix 200. It should be noted that, in some embodiments, the heating component 60 is a structure that can generate heat energy or transfer heat energy to other parts. In some embodiments, the heating component 60 can directly convert other forms of energy such as electrical energy, chemical energy, solar energy, etc. into heat energy, and conduct it to other parts that need to be heated through heat transfer. In other embodiments, the heating component 60 can directly act on other forms of energy such as electromagnetic waves, lasers, infrared light or thermal radiation on the surface of the part to be heated, so as to increase the temperature of the area receiving the electromagnetic waves, lasers, infrared light or thermal radiation.

[0045] Specifically, referring to FIG3 , in some embodiments, the power supply unit 50 and the heating assembly 60 are both disposed within the housing 15, whereby the housing 15 can protect the power supply unit 50 and the heating assembly 60. Specifically, when the detection member 33 detects the moving part 31 (the detected member 315) to confirm that the aerosol generating substrate 200 is accommodated in the heating chamber 11 (as shown in FIG2 ), the detection member 33 can output a heating signal. In this case, the power supply unit 50 can supply power to the heating assembly 60 so that the heating assembly 60 can heat and atomize the aerosol generating substrate 200 according to the heating signal. When the detection member 33 detects the moving part 31 (the detected member 315) to confirm that the aerosol generating substrate 200 is not accommodated in the heating chamber 11 (as shown in FIG3 ), the detection member 33 can output a shutdown signal or stop outputting the heating signal. In this case, the power supply unit 50 will not supply power to the heating assembly 60, and the heating assembly 60 stops heating the aerosol generating substrate 200.

[0046] In some embodiments, the entire moving component 31 may be the detected component 315, thereby improving the accuracy and sensitivity of the detection component 33 in detecting the detected component 315, thereby ensuring the stability and reliability of the operation of the aerosol generating device 100. For example, if the detected component 315 is a magnetic element, the entire moving component 31 can provide a stronger magnetic field, thereby improving the accuracy and sensitivity of the detection by the detection component 33. In other embodiments, a portion of the moving component 31 is the detected component 315, thereby allowing the location of the detected component 315 to be adaptively adjusted based on the installation position of the detection component 33, thereby improving the stability and reliability of the operation of the detection assembly 30.

[0047] It is understood that in other embodiments, the detection member 33 can output other determination signals. For example, when the detection member 33 detects the moving component 31 to confirm that the aerosol-generating substrate 200 is accommodated in the heating chamber 11, the detection member 33 outputs not a heating signal, but a signal that triggers the aerosol generating device 100 to switch from sleep to standby mode. The present embodiment of the application will only illustrate the example of the detection member 33 outputting a heating signal when the detection member 33 detects the moving component 31 to confirm that the aerosol-generating substrate 200 is accommodated in the heating chamber 11.

[0048] In certain embodiments, the body 10 has an opening 13 communicating with the heating chamber 11. The aerosol-generating substrate 200 passes through the opening 13 and is accommodated in the heating chamber 11. When the cover 20 is in a first state, the opening 13 corresponds to the through-hole 21, and the movable member 31 can block the communication between the through-hole 21 and the opening 13. When the cover 20 is in a second state, the opening 13 is open.

[0049] Furthermore, in some embodiments, the main body 10 may also include a bracket 17 installed in the shell 15, the bracket 17 is provided with a heating chamber 11 and an opening 13 connected to the heating chamber 11, and the cover 20 is provided with a through-hole 21 connected to the heating chamber 11, that is, the heating chamber 11 can be connected to the outside world through the through-hole 21, thereby, the aerosol generating matrix 200 can pass through the through-hole 21 and the opening 13 in sequence and extend into the heating chamber 11.

[0050] Specifically, when the aerosol generating substrate 200 extends into the heating chamber 11 through the through-hole 21 and the opening 13, the aerosol generating substrate 200 can push the moving part 31 to move relative to the cover 20 (including moving and rotating) so that the moving part 31 is in a state of opening the through-hole 21, thereby allowing the aerosol generating substrate 200 to pass through the through-hole 21 and the opening 13 in sequence and extend into the heating chamber 11. In this case, the detection member 33 can detect the detected member 315 to confirm that the aerosol generating substrate 200 is accommodated in the heating chamber 11, thereby allowing the heating component 60 to heat the aerosol generating substrate. 200 to generate aerosol for the user to inhale; when the user stops using the aerosol generating device 100, the aerosol generating matrix 200 can be pulled out so that the user can store the aerosol generating device 100. In this case, the moving part 31 can move relative to the cover 20 to be in a state of blocking the perforation 21, and the detection part 33 can detect the detected part 315 to confirm that the aerosol generating matrix 200 is not accommodated in the heating chamber 11, thereby causing the heating component 60 to stop heating the aerosol generating matrix 200, thereby preventing the heating component 60 from being in a heating state and causing damage. In addition, the provision of the moving part 31 can also prevent external impurities such as water or dust from entering the interior of the body 10 through the perforation 21, thereby preventing the components in the body 10 from being damaged, and prevent external impurities such as water or dust from entering the heating chamber 11 through the perforation 21, thereby preventing the aerosol generating matrix 200 from being installed, thereby ensuring the normal operation of the aerosol generating device 100.

[0051] Among them, the aerosol generating substrate 200 is an element that can generate aerosols. Specifically, the aerosol generating substrate 200 can be made into fine particles by heating or ultrasonic vibration, and mixed with air to form an aerosol. The form of the aerosol generating substrate 200 can be solid or liquid, wherein the aerosol generating substrate 200 can be sheet-shaped or columnar, etc. In the present application, the aerosol generating substrate 200 is cylindrical. Aerosols can be visible or invisible and can include vapor (for example, fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The "aerosol" herein covers the aerosol generated when the aerosol generating substrate 200 in the heated aerosol generating device 100 is heated.

[0052] In some embodiments, the first state (as shown in FIG. 2 or FIG. 3 ) may be the state in which the cover 20 is connected to the body 10, the through-hole 21 corresponds to the opening 13, and the movable member 31 is capable of blocking the communication between the through-hole 21 and the opening 13. The second state (as shown in FIG. 5 , FIG. 6 , or FIG. 7 ) may be the state in which the cover 20 is at least partially disconnected from the body 10 and the cover 20 opens the opening 13. It will be understood that in some embodiments, switching the cover 20 between the first state and the second state requires manual intervention, that is, manually switching the cover 20 between the first state and the second state; or manually switching the cover 20 between the first state and the second state with the help of a tool.

[0053] Specifically, in certain embodiments, when the cover 20 is in the first state, if the moving component 31 moves relative to the cover 20 to open the through-hole 21, the moving component 31 can enter the detection range of the detection member 33. If the moving component 31 moves relative to the cover 20 to block the through-hole 21, the detected component 315 exceeds the detection range of the detection member 33. Thus, when the cover 20 is in the first state, the detection member 33 can detect the moving component 31 to confirm whether the aerosol-generating substrate 200 is accommodated in the heating chamber 11. When the cover 20 is in the second state, regardless of whether the moving component 31 is blocking the through-hole 21 or opening the through-hole 21, the detected component 315 exceeds the detection range of the detection member 33. Thus, when the cover 20 is in the second state, the detection member 33 cannot detect the moving component 31 to confirm whether the aerosol-generating substrate 200 is accommodated in the heating chamber 11. It is understandable that, in some embodiments, when the cover 20 is in the second state, the cover 20 opens the opening 13 , thereby allowing a user to clean the heating chamber 11 .

[0054] In the aerosol generating device 100 of the embodiment of the present application, the cover body 20 can switch between a first state and a second state. When the cover body 20 is in the second state, the detected component 315 is beyond the detection range of the detection component 33. Therefore, the moving component 31 does not affect the user's cleaning operation, thereby facilitating the user to clean the heating chamber 11, reducing the user's operating burden and improving cleaning efficiency.

[0055] In addition, since residues may remain in the heating chamber 11 when the aerosol generating substrate 200 is removed from the heating chamber 11, the user needs to clean the interior of the heating chamber 11 to prevent the residues from affecting the installation and heating of the aerosol generating substrate 200. Generally, the user can use a tool (such as a cotton swab, etc.) to reach into the heating chamber 11 to clean the heating chamber 11. However, during the process of the tool being inserted into the heating chamber 11, the moving part 31 can rotate relative to the cover 20 to be in a state of opening the perforation 21. At this time, the moving part 31 is within the detection range of the detection member 33. As a result, the heating assembly 60 will not be started to heat as expected by the user, thereby affecting the user's normal cleaning. In the embodiment of the present application, when the cover body 20 is in the second state, the cover body 20 opens the opening 13, and the detected member 315 is beyond the detection range of the detection member 33. Therefore, when the user cleans the heating chamber 11, the detection member 33 will not cooperate with the moving part 31 to output a heating signal, that is, the heating component 60 will not be mistakenly started, thereby ensuring that the user can clean the heating chamber 11 normally.

[0056] The aerosol generating device 100 will be further described below with reference to the accompanying drawings.

[0057] Referring to Figures 2 to 4 , in some embodiments, the moving component 31 can rotate relative to the cover 20 to switch between a state in which the perforations 21 are blocked and a state in which the perforations 21 are exposed. In other embodiments, the moving component 31 can move relative to the cover 20 to switch between a state in which the perforations 21 are blocked and a state in which the perforations 21 are exposed. It should be noted that in the embodiments of the present application, only the example in which the moving component 31 can rotate relative to the cover 20 to switch between a state in which the perforations 21 are blocked and a state in which the perforations 21 are exposed is used for illustration.

[0058] Referring to Figures 2 to 4, in some embodiments, the moving component 31 includes a rotating shaft 311, a shielding member 313, a detected member 315, and an elastic member 317. The rotating shaft 311 is rotatably mounted on the cover body 20. The shielding member 313 is connected to the rotating shaft 311 and can rotate together with the rotating shaft 311. The detected member 315 is arranged on the shielding member 313 and can rotate together with the shielding member 313. The detected member 315 is used to cooperate with the detecting member 33. The elastic member 317 is connected to the rotating shaft 311 and the shielding member 313 and is used to provide an elastic force. When the shielding member 313 rotates along the first direction X, the shielding member 313 is in a state of opening the perforation 21. The elastic force is used to rotate the shielding member 313 along the second direction Y so that the shielding member 313 is in a state of blocking the perforation 21. The second direction Y is opposite to the first direction X. It should be noted that in some embodiments, the elastic member 317 includes but is not limited to a compression spring or a tension spring.

[0059] Specifically, in some embodiments, the moving part 31 may be arranged on the side of the cover 20 facing the main body 10, whereby, in the process of the aerosol generating matrix 200 extending into the heating chamber 11 through the perforation 21, the force exerted by the aerosol generating matrix 200 on the shielding member 313 is greater than the elastic force exerted by the elastic member 317 on the shielding member 313, thereby enabling the shielding member 313 to rotate toward the direction of the main body 10 (i.e., rotate along the first direction X) to be in a state of opening the perforation 21; in the process of the aerosol generating matrix 200 being pulled out of the heating chamber 11, the force exerted by the aerosol generating matrix 200 on the shielding member 313 gradually disappears, thereby enabling the shielding member 313 to rotate in a direction away from the main body 10 (i.e., rotate along the second direction Y) under the action of the elastic force of the elastic member 317 to be in a state of blocking the perforation 21. It should be noted that the cross-sectional size of the shielding member 313 is greater than or equal to the cross-sectional size of the perforation 21, thereby ensuring the shielding effect of the shielding member 313 on the perforation 21 and preventing external impurities such as water or dust from entering the heating chamber 11 through the perforation 21.

[0060] Please continue to refer to Figures 2 to 4. In some embodiments, when the cover body 20 is in the first state, if the shielding member 313 rotates relative to the cover body 20 along the first direction X to open the through-hole 21, the shielding member 313 can drive the detected member 315 to rotate so that the detected member 315 enters the detection range of the detection member 33; if the shielding member 313 rotates relative to the cover body 20 along the second direction Y to block the through-hole 21, the detected member 315 exceeds the detection range of the detection member 33. Therefore, when the cover body 20 is in the first state, the detection member 33 can detect the detected member 315 to confirm whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0061] Please refer to Figures 5 to 7. In other embodiments, when the cover body 20 is in the second state, regardless of whether the blocking member 313 blocks or opens the perforation 21, the detected member 315 is beyond the detection range of the detection member 33. Therefore, when the cover body 20 is in the second state, the detection member 33 cannot detect the detected member 315 to confirm whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0062] In some embodiments, the detected part 315 may be arranged on the shielding member 313 in a non-detachable connection manner, thereby improving the bonding strength between the detected part 315 and the shielding member 313 and preventing the detected part 315 from falling off the shielding member 313 during the rotation of the shielding member 313, thereby ensuring the normal operation of the detection component 30. Among them, the non-detachable connection manner includes but is not limited to bonding or welding. In other embodiments, the detected part 315 may be arranged on the shielding member 313 in a detachable connection manner, thereby facilitating the removal of the detected part 315 for repair or replacement when it is damaged, thereby ensuring the normal operation of the detection component 30. Among them, the detachable connection manner includes but is not limited to snap connection or threaded connection. It is understandable that the second connecting member 43 may also be arranged on the main body 10 in a non-detachable or detachable connection manner.

[0063] In some embodiments, the detection element 33 may be a Hall switch, a photoelectric sensor, or a collision sensor, etc., without limitation. The detected element 315 may be a device that cooperates with the detection element 33 so that the detection element 33 can confirm whether the aerosol-generating substrate 200 is placed in the heating chamber 11.

[0064] Specifically, in some embodiments, the detecting element 33 may be a Hall switch, and the detected element 315 may be a magnetic element (e.g., a permanent magnet). The Hall switch is used to detect the magnetic field of the magnetic element to determine whether the perforation is in an open or closed state. In other words, the Hall switch can confirm whether the aerosol-generating substrate 200 is contained in the heating chamber 11 based on the magnetic field of the magnet. When the aerosol-generating substrate 200 is contained in the heating chamber 11, the detecting element 33 can output a heating signal to heat the aerosol-generating substrate 200 to generate an aerosol. In other embodiments, the detecting element 33 may be either the transmitting end or the receiving end of a photoelectric sensor. In this case, the detected element 315 may be the other of the transmitting end and the receiving end. Thus, the detecting element 33 can confirm whether the aerosol-generating substrate 200 is contained in the heating chamber 11 based on whether it receives the light signal emitted by the transmitting end.

[0065] 2 and 5 , in some embodiments, when the cover 20 is in the second state, the cover 20 is separated from the body 10. Specifically, in some embodiments, when the cover 20 is manually separated from the body 10, the cover 20 is in the second state. In this state, the heating chamber 11 is fully open, that is, the heating chamber 11 can communicate with the outside world through the opening 13, thereby facilitating the user's cleaning of the heating chamber 11.

[0066] Referring to Figures 2, 6, and 7, in other embodiments, when the cover 20 is in the second state, the cover 20 is at least partially connected to the body 10. Specifically, in some embodiments, when the cover 20 is manually intervened to at least partially separate the cover 20 from the body 10, the cover 20 is in the second state. In this case, the heating chamber 11 can also be in a fully open state, that is, the heating chamber 11 can be connected to the outside world through the opening 13, thereby facilitating the user to clean the heating chamber 11. In addition, compared to completely separating the cover 20 from the body 10, at least partially connecting the cover 20 to the body 10 can prevent the cover 20 from being lost, thereby improving the user experience.

[0067] Please refer to Figure 6. In some embodiments, the cover 20 can move relative to the body 10 so that the cover 20 opens the opening 13 or aligns the opening 13 with the through-hole 21. Specifically, when the cover 20 is in the first state, the opening 13 can be aligned with the through-hole 21, that is, the central axis of the opening 13 can coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the moving part 31 can block or open the communication between the through-hole 21 and the opening 13; when the cover 20 moves (slides) relative to the body 10 to change from the first state to the second state, the cover 20 is at least partially connected to the body 10, and the cover 20 can open the opening 13, the central axis of the opening 13 does not coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0068] Please refer to Figure 7. In other embodiments, the cover 20 can rotate relative to the body 10 so that the cover 20 opens the opening 13 or aligns the opening 13 with the through-hole 21. Specifically, when the cover 20 is in the first state, the opening 13 can be aligned with the through-hole 21, that is, the central axis of the opening 13 can coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the moving part 31 can block or open the connection between the through-hole 21 and the opening 13; when the cover 20 rotates relative to the body 10 (including translation or flipping, etc.) to change from the first state to the second state, the cover 20 is at least partially connected to the body 10, and the cover 20 can open the opening 13, the central axis of the opening 13 does not coincide with the central axis of the through-hole 21, and when the moving part 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0069] Referring to FIG. 2 , in some embodiments, the aerosol generating device 100 may further include a connecting assembly 40 (e.g., adhesive, screws, buckles, magnets, etc.) for connecting the body 10 and the cover 20. It should be noted that in some embodiments, the connecting assembly 40 includes, but is not limited to, bolts, buckles, or magnetic components.

[0070] Specifically, in some embodiments, the cover 20 and the body 10 can be detachably connected using a connecting assembly 40, so that the cover 20 can switch between a first state and a second state, thereby aligning the opening 13 with the through-hole 21 or allowing the cover 20 to open the opening 13. When the cover 20 is connected to the body 10 via the connecting assembly 40, the cover 20 is in the first state, and the opening 13 can be aligned with the through-hole 21. In this state, the moving component 31 can rotate relative to the cover 20 to block or open the communication between the through-hole 21 and the opening 13. When the cover 20 is detached from the body 10, the cover 20 changes from the first state to the second state, and the cover 20 can open the opening 13. In this state, when the moving component 31 rotates relative to the cover 20, the heating chamber 11 can always communicate with the outside through the opening 13.

[0071] 2 , in some embodiments, the connecting assembly 40 includes a first connecting member 41 and a second connecting member 43. The first connecting member 41 is disposed on the cover 20. The second connecting member 43 is disposed in the body 10. The first connecting member 41 and the second connecting member 43 cooperate to connect the cover 20 to the body 10.

[0072] In some embodiments, the first connector 41 may be attached to the cover 20 using a non-detachable connection. This improves the bonding strength between the first connector 41 and the cover 20 and prevents the first connector 41 from falling off the cover 20 when the first connector 41 and the second connector 43 are disconnected, thereby improving the stability and reliability of the connection between the cover 20 and the body 10. Examples of non-detachable connection methods include, but are not limited to, bonding or welding. In other embodiments, the first connector 41 may be attached to the cover 20 using a non-detachable connection method. This facilitates removal and replacement of the first connector 41 if damaged, thereby ensuring proper connection between the cover 20 and the body 10. Examples of detachable connection methods include, but are not limited to, snap-fit ​​or threaded connections. It is understood that the second connector 43 may be attached to the body 10 using either a non-detachable or detachable connection method. Examples of non-detachable connection methods include, but are not limited to, bonding or welding; examples of detachable connection methods include, but are not limited to, snap-fit ​​or threaded connections.

[0073] Furthermore, in some embodiments, one of the first connecting member 41 and the second connecting member 43 is a magnetic member, and the other is an adsorbent member, and the magnetic member cooperates with the adsorbent member to connect the cover 20 to the body 10. Specifically, when the first connecting member 41 and the second connecting member 43 are close to each other, the magnetic field of the magnetic member can act on the adsorbent member to generate an attractive force on the adsorbent member, and this attractive force can connect the cover 20 to the body 10.

[0074] In some embodiments, the adsorption member may be made of iron or a soft magnetic material. For example, when the adsorption member is made of a soft magnetic material, when the magnetic member and the adsorption member are in contact (including direct contact or indirect contact), the adsorption member can generate a magnetic field under the action of the magnetic member's magnetic field and attract the magnetic member, thereby achieving the adsorption member and the magnetic member to cooperate, thereby achieving the connection between the cover 20 and the body 10.

[0075] In some embodiments, the magnetic member is disposed on the cover 20 and the adsorption member is disposed on the main body 10, thereby increasing the distance between the magnetic member and the detection member 33, preventing the magnetic field of the magnetic member from interfering with the detection member 33, and thereby improving the accuracy of the detection member 33 in detecting whether the aerosol generating matrix 200 is accommodated in the heating chamber 11.

[0076] In other embodiments, the magnetic member is disposed on the body 10 and the adsorption member is disposed on the cover 20. In this case, to prevent the magnetic field of the magnetic member from interfering with the detection member 22, the aerosol generating device 100 may further include a barrier (not shown), which is disposed over the magnetic member and is used to block the magnetic field of the magnetic member from being directed toward the detection member 33. This can reduce or even prevent the magnetic field of the magnetic member from interfering with the detection member 33, thereby further improving the accuracy of the detection member 33 in detecting whether the aerosol generating substrate 200 is accommodated in the heating chamber 11. It should be noted that in some embodiments, the barrier can be made of materials such as low-carbon steel, silicon steel, or silicon steel sheet.

[0077] It is understandable that, in conjunction with Figure 7, in some embodiments, in addition to the first connecting member 41 and the second connecting member 43, the connecting assembly 40 may further include a third connecting member (not shown), and the cover 20 may be rotatably connected to the main body 10 via the third connecting member. Thus, when the first connecting member 41 and the second connecting member 43 are released from engagement, part of the structure of the cover 20 can remain connected to the main body 10 via the third connecting member, and the cover 20 can be rotated relative to the main body 10 via the third connecting member to transform the cover 20 from the first state to the second state. In this case, the cover 20 opens the opening 13, and the detected member 315 exceeds the detection range of the detection member 33. It should be noted that, in some embodiments, the third connecting member may be a hinge or a rotation member, etc., which is not limited here.
