[0046] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] The first aspect of this utility model embodiment provides an aerosol generating device 100, such as... Figures 1 to 4As shown, the aerosol generating device 100 includes a main unit 110 and a media cartridge 120. The main unit 110 includes a main unit housing 111 and an outer cover 112 covering the main unit housing 111. The main unit housing 111 has a receiving cavity 113 with an opening for inserting and removing the media cartridge 120. The media cartridge 120 is detachably disposed within the receiving cavity 113. The media cartridge 120 includes a first housing 121 and a second housing 122, and a feeding assembly disposed within the first housing 121 and the second housing 122. The feeding assembly includes a first reel 123 and a second reel 124. The first reel 123... The first and second reels 123 and 124 are spaced apart and installed inside the media box 120. The media box 120 also includes a matrix belt 125, which is wound around the first reel 123 and the second reel 124 and connected to the first reel 123 and the second reel 124. The media box 120 has an atomizing chamber 127 and a filter 126, which are in communication with the filter 126. The first reel 123 and the second reel 124 are used to transport the matrix belt 125, which can generate aerosol, so that the matrix belt 125 moves in the media box 120, thereby being heated in the atomizing chamber 127 to generate aerosol, which is then discharged for the user to inhale.

[0051] The matrix strip 125 is a flexible strip structure with a certain width and thickness, but its length can be extended and bent according to actual conditions. The surface of the matrix strip 125 is coated or the interior is infiltrated or embedded with an aerosol generating matrix for generating aerosols. The aerosol generating matrix includes, but is not limited to, pharmaceuticals or nicotine-containing materials.

[0052] The main unit 110 inside the aerosol generating device 100 starts heating under suction action or control command. When the media box 120 is not installed or not installed properly, there is ineffective heating, consuming electrical energy, increasing energy consumption, or even damaging the main unit housing 111 due to ineffective heating. To achieve installation detection of the media box 120 and provide reliable heating conditions, such as... Figure 5 and Figure 6 As shown, the receiving cavity 113 and the medium box 120 are respectively provided with a magnetic element 130 and a magnetic switch circuit 140. The receiving cavity 113 is provided with a magnetic element 130 and the medium box 120 is provided with a magnetic switch circuit 140, or the receiving cavity 113 is provided with a magnetic switch circuit 140 and the medium box 120 is provided with a magnetic element 130. The magnetic element 130 magnetically attracts the receiving cavity 113 or the medium box 120, thereby fixing the medium box 120 in the receiving cavity 113.

[0053] The magnetic component 130 has a certain magnetism and forms a magnetic field of a certain size around it. The magnetic switch circuit 140 is configured to switch the switch state when the distance between it and the magnetic component 130 changes, and outputs an electrical signal that indicates whether the medium box 120 is installed in a preset position.

[0054] For example, when the media cartridge 120 is not installed or is installed in the receiving cavity 113 but not in the preset position, if the distance between the magnetic component 130 and the magnetic switch circuit 140 is greater than the preset distance, the magnetic field strength received by the magnetic switch circuit 140 does not reach the preset magnetic field strength. The magnetic switch circuit 140 maintains the first switch state and outputs a first electrical signal indicating that the media cartridge 120 is not installed in place.

[0055] When the media cartridge 120 is installed into the receiving cavity 113 and reaches the preset position, when the distance between the magnetic component 130 and the magnetic switch circuit 140 is equal to or less than the preset distance, the magnetic field strength received by the magnetic switch circuit 140 reaches the preset magnetic field strength, the magnetic switch circuit 140 switches from the first switch circuit to the second switch state, and switches to output a second electrical signal indicating that the media cartridge 120 is installed in place.

[0056] When the media cartridge 120 is pulled out of the receiving cavity 113 and the distance between the magnetic component 130 and the magnetic switch circuit 140 is greater than a preset distance, the magnetic field strength received by the magnetic switch circuit 140 does not reach the preset magnetic field strength. The magnetic switch circuit 140 switches from the second switch state to the first switch state and switches to output a first electrical signal indicating that the media cartridge 120 is not installed in place.

[0057] The magnetic switch circuit 140 is also connected to the functional components inside the host 110. The functional components can determine whether the media box 120 is installed in place based on the electrical signal fed back by the magnetic switch circuit 140, and perform corresponding heating control, locking of the media box 120, etc. After the media box 120 is installed in place, the host 110 can further start the heating action to heat the media box 120, thereby generating aerosol for users. This solves the safety and energy consumption problems caused by the failure or lack of detection of the traditional media box 120 installation detection method, and improves the safety and operational reliability of the aerosol generating device 100.

[0058] Furthermore, to prevent displacement of the medium cartridge 120 after installation, which could lead to abnormal heating and atomization, in an optional embodiment, the aerosol generating device 100 further includes:

[0059] The locking mechanism 150 is disposed in the receiving cavity 113 and connected to the magnetic switch circuit 140, and is configured to trigger the locking of the media cartridge 120 when an electrical signal indicating that the media cartridge 120 is installed in a preset position is received.

[0060] The locking mechanism 150 is used to trigger a locking action and lock the media cartridge 120 into the receiving cavity 113 when the media cartridge 120 is inserted into the receiving cavity 113 and reaches a preset position, so as to prevent the media cartridge 120 from becoming loose during use.

[0061] The locking mechanism 150 can be disposed on the top or side 1132 of the receiving cavity 113. When disposed on the top of the receiving cavity 113, when the locking action is triggered, the locking mechanism 150 extends from the top and is horizontally disposed on the top of the media box 120, thereby limiting the media box 120 within the receiving cavity 113. When disposed on the side 1132 of the receiving cavity 113, when the locking action is triggered, the locking mechanism extends from the side 1132 and presses against the media box 120, thereby limiting the media box 120 within the receiving cavity 113. The locking member 153 of the locking mechanism 150 can be provided as one or more, and the number of locking members 153 is specifically set according to the limiting requirements.

[0062] When the media cartridge 120 is installed in place, the locking mechanism 150 receives a second electrical signal indicating that the media cartridge 120 is installed in a preset position. The locking mechanism 150 triggers a locking action, and the locking mechanism 150 triggers the internal locking member 153 to extend and lock the media cartridge 120, thereby limiting the media cartridge 120 in the receiving cavity 113 and preventing the media cartridge 120 from becoming loose during use.

[0063] After the media box 120 is installed in place, the aerosol generating device 100 can trigger the heating and atomization operation according to the trigger command or the suction action. The aerosol generating matrix in the media box 120 can be further heated and atomized in the aerosol generating device 100 to generate aerosol for user use.

[0064] It should be noted that when the receiving cavity 113 is provided with a magnetic component 130 and the medium box 120 is provided with a magnetic switch circuit 140, the magnetic switch circuit 140 and the locking mechanism 150 can be connected and communicated directly or indirectly. For example, the medium box 120 is provided with a first metal contact and the receiving cavity 113 is provided with a second metal contact. The first metal contact is connected to the magnetic switch circuit 140 and the second metal contact is connected to the locking mechanism 150. When the medium box 120 is installed in the receiving cavity 113, the metal contacts of the medium box 120 and the receiving cavity 113 are in contact. When the magnetic switch circuit 140 switches the switch state and outputs an electrical signal, it outputs an electrical signal to the locking mechanism 150 through the metal contact.

[0065] Alternatively, a wireless module may be provided on the magnetic switch circuit 140 and the locking mechanism 150, and the electrical signal output by the magnetic switch circuit 140 may be transmitted to the locking mechanism 150 through the wireless module.

[0066] When a magnetic switch circuit 140 is provided in the receiving cavity 113 and a magnetic component 130 is provided on the medium box 120, the magnetic switch circuit 140 and the locking mechanism 150 provided in the receiving cavity 113 can be directly connected by wires or wirelessly, and the specific connection method is not limited.

[0067] Furthermore, when a magnetic component 130 is provided in the receiving cavity 113 and a magnetic switch circuit 140 is provided on the media cartridge 120, since the media cartridge 120 is a consumable, the design cost of the magnetic switch circuit 140 is relatively high. When replacing the magnetic component 130, the usage cost increases. In order to reduce costs, in an optional embodiment, the magnetic component 130 is provided in the media cartridge 120, and the magnetic switch circuit 140 is at least partially provided in the main unit housing 111 or the receiving cavity 113. After the media cartridge 120 is used up, it can be removed from the receiving cavity 113 and a new media cartridge 120 can be replaced. Since the magnetic component 130 has a simple structure and low cost, the cost caused by consumables can be reduced when replacing the media cartridge 120.

[0068] The locking mechanism 150 may adopt a locking element 153, a controller 151, or other structures. In an optional embodiment, such as... Figure 15 As shown, the locking mechanism 150 includes a locking element 153, a controller 151, and a motor 152. The locking element 153 is disposed in the receiving cavity 113. The locking element 153 can be disposed at the top or side 1132 of the receiving cavity 113. When disposed at the top of the receiving cavity 113, when the locking action is triggered, the locking element 153 extends from the top and is horizontally disposed at the top of the media box 120, thereby limiting the media box 120 within the receiving cavity 113. When disposed at the side 1132 of the receiving cavity 113, when the locking action is triggered, the locking element 153 extends from the side 1132 and presses against the media box 120, thereby limiting the media box 120 within the receiving cavity 113. The locking mechanism 150 can have one or more locking elements 153, and the number of locking elements 153 is specifically set according to the limiting requirements.

[0069] The locking element 153 can be a crossbar or a transmission structure, etc. When the motor 152 rotates, it drives the locking element 153 to move and lock or release the medium box 120.

[0070] The controller 151 is connected to the magnetic switch circuit 140. The controller 151 is configured to trigger the output motor drive signal when it receives an electrical signal indicating that the medium cartridge 120 is installed in a preset position. Specifically, the controller 151 cuts off the output motor drive signal to the motor 152 when it receives a first electrical signal indicating that the medium cartridge 120 is not installed in the preset position, and triggers the output motor drive signal to the motor 152 when it receives a second electrical signal indicating that the medium cartridge 120 is installed in the preset position.

[0071] Motor 152 is connected to controller 151 and locking member 153 respectively. Motor 152 stops operating when it does not receive a drive signal from motor 152, and locking member 153 does not trigger locking action. Media box 120 can be freely inserted and pulled out in receiving cavity 113. When motor 152 receives a drive signal from motor 152, motor 152 is triggered to rotate and drive locking member 153 to move, so as to lock media box 120.

[0072] Furthermore, in order to achieve the heating and atomization of the aerosol generation matrix, in an optional embodiment, such as... Figure 4 As shown, the aerosol generating device 100 also includes a heating component 115, which is disposed in the main housing 111. After the medium box 120 is installed into the receiving cavity 113, the heating component 115 extends at least partially into the atomization cavity 127 of the medium box 120. The heating component 115 is configured to heat the matrix strip 125.

[0073] The heating component 115 starts the heating conveyor belt 11 according to the enable signal to heat the substrate belt 125 to generate aerosol. The enable signal can be an electrical signal generated by the suction action or an electrical signal corresponding to the control command. The heating component 115 can directly heat the aerosol generating substrate set on the conveyor belt 11, or heat the conveyor belt 11 to indirectly heat the aerosol generating substrate through the conveyor belt 11 to heat the substrate belt 125 to generate aerosol.

[0074] To improve the heating effect, in an optional embodiment, the heating component 115 is also connected to the magnetic switch circuit 140 and receives the electrical signal output by the magnetic switch circuit 140. The position of the medium box 120 is determined according to the electrical signal. For example, when the medium box 120 is not installed or is not installed to the preset position, the heating component 115 receives the first electrical signal output by the magnetic switch circuit 140, and the heating component 115 stops heating. When the medium box 120 is installed to the preset position of the receiving cavity 113, the heating component 115 receives the second electrical signal output by the magnetic switch circuit 140, and the heating component 115 starts heating. This allows the heating component 115 to stop heating the medium box 120 when it is not installed or removed, and to start heating when the medium box 120 is installed to the preset position. This avoids continuous heating by the heating component 115, reduces energy consumption, and further improves the working safety and reliability of the aerosol generating device 100.

[0075] In order to achieve heating at a designated location and avoid damage to other components of the medium box 120 due to heating, in an optional embodiment, the heating assembly 115 includes a magnetic coil assembly disposed in the main housing 111. The magnetic coil assembly 13 is used to generate a magnetic field according to an enable signal. The magnetic coil assembly 13 extends at least partially out of the atomization chamber 127 and is disposed adjacent to the matrix strip 125.

[0076] The magnetic coil assembly 13 includes an LC resonant circuit, which includes an inductor, a capacitor, and a switch. The inductor and capacitor are connected in parallel and then connected in series with the switch across the power supply circuit. When the switch receives a PWM signal, it drives the inductor and capacitor to resonate and generate a magnetic field. The inductor is at least partially located in the atomization chamber 127. The generated magnetic field is emitted to the atomization chamber 127 and heats the matrix strip 125.

[0077] Correspondingly, the substrate strip 125 is provided with an element that can be heated by eddy currents in a magnetic field. In an optional embodiment, the substrate strip 125 includes a strip substrate and an aerosol generating matrix disposed on the strip substrate. The strip substrate can be heated under the magnetic field generated by the magnetic induction coil assembly. Alternatively, the strip substrate or the aerosol generating matrix is ​​provided with a sensor that can be heated under the magnetic field generated by the magnetic induction coil assembly.

[0078] The strip substrate or sensor is a metal structure that can generate eddy currents under the action of a magnetic field and heat aerosol to form a matrix. The generated aerosol is then available for user use. Electromagnetic heating can be used to specifically heat the matrix strip 125 without affecting other components.

[0079] When the substrate strip 125 is provided with a sensor, the sensor can be spaced apart on the strip substrate or in the aerosol generating substrate. When the substrate strip 125 moves to the atomization chamber 127 along with the first roll 123 and the second roll 124, it receives the magnetic field of the magnetic coil assembly and generates eddy currents and heating, and heats the aerosol generating substrate that moves to the atomization chamber 127 to generate aerosol for the user.

[0080] The magnetic component 130 can be an electromagnet, magnetic pole 131, or other structures with magnetic properties. The number of magnetic components 130 can be set according to requirements. In an optional embodiment, such as... Figure 7 and Figure 8 As shown, the magnetic component 130 includes a magnetic pole 131, and the magnetic switch circuit 140 includes a magnetic switch unit 141. The magnetic switch unit 141 is positioned opposite to the magnetic pole 131 when the media cartridge 120 is installed in a preset position. The magnetic switch unit 141 is configured to switch the switch state when the distance between it and the oppositely positioned magnetic pole 131 changes, and outputs an electrical signal indicating whether the media cartridge 120 is installed in the preset position.

[0081] For example, when the medium cartridge 120 is not installed or is installed in the receiving cavity 113 but not in the preset position, if the distance between the magnetic pole 131 and the magnetic switch unit 141 is greater than the preset distance, the magnetic field received by the magnetic switch unit 141 does not reach the preset magnetic field size. The magnetic switch unit 141 maintains the first switch state and outputs the first electrical signal indicating that the medium cartridge 120 is not installed in place.

[0082] When the media cartridge 120 is installed into the receiving cavity 113 and reaches the preset position, when the distance between the magnetic pole 131 and the magnetic switch unit 141 is equal to or less than the preset distance, the magnetic field received by the magnetic switch unit 141 reaches the preset magnetic field size, the magnetic switch unit 141 switches from the first switch circuit to the second switch state, and switches to output a second electrical signal indicating that the media cartridge 120 is installed in place.

[0083] And when the medium cartridge 120 is pulled out of the receiving cavity 113 and the distance between the magnetic pole 131 and the magnetic switch unit 141 is greater than a preset distance, the magnetic field received by the magnetic switch unit 141 does not reach the preset magnetic field size. The magnetic switch unit 141 switches from the second switch state to the first switch state and switches to output a first electrical signal indicating that the medium cartridge 120 is not installed in place.

[0084] The locking mechanism 150 triggers a locking action or stops triggering the locking action when it receives a corresponding electrical signal, and the heating component 115 triggers the generation of a magnetic field or stops generating a magnetic field when it receives a corresponding electrical signal.

[0085] Alternatively, in another optional embodiment, the magnetic element 130 includes a plurality of magnetic poles 131 that are spaced apart. The plurality of magnetic poles 131 can be spaced apart along different directions, for example, spaced apart along the lateral direction of the bottom 1131 or side 1132 of the medium box 120, or spaced apart along the lateral direction of the first housing 121 or side of the medium box 120. The specific arrangement is not limited.

[0086] Correspondingly, relative to the number and direction of the magnetic poles 131, the magnetic switch circuit 140 includes a plurality of magnetic switch units 141. When the medium box 120 is installed in a preset position, the plurality of magnetic switch units 141 are arranged one-to-one with the plurality of magnetic poles 131. For example, the plurality of magnetic switch units 141 are arranged one-to-one with the plurality of magnetic poles 131.

[0087] For example Figure 9 and Figure 11 As shown, the magnetic component 130 includes two magnetic poles 131. When the two magnetic poles 131 are spaced apart along the transverse or longitudinal direction of the first housing 121 of the medium box 120, such as... Figure 10 and Figure 12 As shown, the magnetic switch circuit 140 includes two magnetic switch units 141. The magnetic switch units 141 are spaced apart along the lateral or longitudinal direction of the bottom 1131 or side 1132 of the receiving cavity 113. When the medium box 120 is installed in the preset position, one magnetic pole 131 and one magnetic switch unit 141 are arranged opposite to each other, and the other magnetic pole 131 and the other magnetic switch unit 141 are arranged opposite to each other or adjacent to each other.

[0088] The magnetic switch unit 141 is configured to switch the switch state when the distance between it and the oppositely arranged magnetic pole 131 changes, and outputs an electrical signal indicating whether the medium box 120 is installed in a preset position.

[0089] When the medium cartridge 120 is not installed or is installed in the receiving cavity 113 but not in the preset position, and the distance between the two magnetic poles 131 and the two magnetic switch units 141 is greater than the preset distance, the magnetic field received by the two magnetic switch units 141 does not reach the preset magnetic field size. The two magnetic switch units 141 maintain the first switch state and output the first electrical signal indicating that the medium cartridge 120 is not installed in place.

[0090] When the media cartridge 120 is installed into the receiving cavity 113 and reaches the preset position, when the distance between the two magnetic poles 131 and the two magnetic switch units 141 is equal to or less than the preset distance, the magnetic field received by the two magnetic switch units 141 reaches the preset magnetic field size. Both magnetic switch units 141 switch from the first switch circuit to the second switch state and respectively switch to output the second electrical signal indicating that the media cartridge 120 is installed in place.

[0091] And when the medium cartridge 120 is pulled out of the receiving cavity 113 and the distance between the two magnetic poles 131 and the two magnetic switch units 141 is greater than a preset distance, the magnetic field received by the two magnetic switch units 141 does not reach the preset magnetic field size. The two magnetic switch units 141 switch from the second switch state to the first switch state and switch to output the first electrical signal indicating that the medium cartridge 120 is not installed in place.

[0092] The locking mechanism 150 stops triggering the locking action when it receives two corresponding first electrical signals, and triggers the locking action when it receives two corresponding second electrical signals.

[0093] The heating component 115 is triggered to stop generating a magnetic field when it receives two corresponding first electrical signals, and generates a magnetic field when it receives two corresponding second electrical signals.

[0094] The magnetic switch unit 141 can adopt a structure such as magnetic switch K1, for example... Figure 13 As shown, in an optional embodiment, the magnetic switch unit 141 includes a first resistor R1, a magnetic switch K1, and a second resistor R2 connected in sequence to the positive voltage terminal VCC and the ground terminal. The first or second terminal of the magnetic switch K1 is used to output an electrical signal.

[0095] The magnetic switch K1 has a magnetic structure inside, including a magnet and a magnetic pole 131, as well as a switching structure. When the magnetic structure is close to or far from the magnetic component 130, the magnetic structure drives the switching structure or resets the switching structure, thereby switching the switching state of the magnetic switch K1.

[0096] When the distance between the magnetic switch K1 and the magnetic pole 131 has not reached the preset distance, that is, when the medium box 120 has not reached the preset position, the magnetic switch K1 maintains the first switching state, and the first or second end of the magnetic switch K1 outputs the first voltage signal. When the distance between the magnetic switch K1 and the magnetic pole 131 reaches the preset distance, that is, when the medium box 120 reaches the preset position, the magnetic switch K1 switches to the second switching state, and the first or second end of the magnetic switch K1 outputs the second voltage signal. The locking structure cuts off the locking action when it receives the first voltage signal, and triggers the locking action when it receives the second voltage signal.

[0097] The magnetic switch K1 can be configured according to the requirements of the magnetic structure, the switch structure and the switching method. In an optional embodiment, in order to simplify the circuit structure and reduce the design cost, the magnetic switch K1 is a reed switch. The reed switch consists of a glass tube and two springs. The inner end of the spring is sealed in the glass tube. The two springs are overlapping and there is a small gap between them. When the magnetic field of the magnetic component 130 is received, the two springs will make contact and conduct. When the magnetic field of the magnetic component 130 weakens or disappears, the springs will separate due to their own elasticity, thereby disconnecting the magnetic switch K1.

[0098] Furthermore, in order to further limit and fix the media box 120, such as Figure 14 As shown, the bottom 1131 of the receiving cavity 113 is also provided with a mounting base 116 for fixing the media box 120, and a magnetic switch is provided on the mounting base 116.

[0099] The magnetic pole 131 is disposed on the side of the medium box 120 facing the receiving cavity 113. When the medium box 120 is installed on the mounting base 116, the magnetic pole 131 is in contact with or near the magnetic switch.

[0100] The mounting base 116 can be disposed within or through the receiving cavity 113. When the media box 120 is installed on the mounting base 116, it indicates that the media box 120 has reached the preset position. The magnetic pole 131 is in contact with or near the magnetic switch K1, and the magnetic switch K1 is triggered to switch the state, thereby triggering the locking mechanism 150 to lock the media box 120 and triggering the heating component 115 to heat.

[0101] Correspondingly, such as Figure 2 As shown, the main unit 110 also includes a drive assembly 114. The drive assembly 114 is disposed inside the main unit housing 111 and partially extends into the receiving cavity 113. It is connected to the first reel 123 and the second reel 124. When the drive assembly 114 rotates, it drives the first reel 123 or the second reel 124 to rotate, thereby driving the substrate belt 125 to move between the first reel 123 or the second reel 124.

[0102] The drive assembly 114 is detachably connected to the axis of the first reel 123 and the second reel 124. When the media cartridge 120 is installed into the receiving cavity 113, the drive assembly 114 is coaxially connected to the first reel 123 or the second reel 124, and rotates under the drive signal, thereby driving the first reel 123 and the second reel 124 to rotate and driving the substrate belt 125 to move.

[0103] The beneficial effects of this utility model embodiment compared with the prior art are as follows: The above-mentioned aerosol generating device 100 includes a main housing 111 and a medium box 120. The main housing 111 is provided with a receiving cavity 113. A magnetic component 130 and a magnetic switch circuit 140 are respectively provided on the receiving cavity 113 and the medium box 120. When the medium box 120 is installed into the receiving cavity 113 of the main housing 111, the distance between the magnetic switch circuit 140 and the magnetic component 130 changes. The magnetic switch circuit 140 switches the switch state and outputs an electrical signal indicating whether the medium box 120 is installed in a preset position. Based on the electrical signal, it can be determined whether the medium box 120 is installed in place. After the medium box 120 is installed in place, the aerosol generating device 100 can further heat the medium box 120 to generate aerosol for user use. This solves the safety and energy consumption problems caused by the failure or lack of detection of the traditional medium box 120 installation detection method, and improves the safety and operational reliability of the aerosol generating device 100.
