Abstract

The present invention provides an aerosol generating device and a method for controlling an aerosol generating device. [Solution] The aerosol generating device includes a housing having a storage chamber and capable of being closed after the storage chamber is opened, a microwave generator located within the storage chamber and having a microwave control circuit, and a first detection member provided in the storage chamber. The first detection member is electrically connected to the microwave control circuit, and when the first detection member detects that the storage chamber has been opened, the microwave control circuit is disconnected. When the first detection member detects that the storage chamber has been opened, a detection signal from the first detection member is sent to a controller, which controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves should be applied to an aerosol substrate to generate an aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, and therefore microwaves are not generated. This prevents microwave leakage from harming the user.

Description

[Technical field]

[0001] The present invention relates to the technical field of electronic smoking devices, and more particularly to an aerosol generating device and a method for controlling the aerosol generating device. [Background technology]

[0002] The Heat Not Burning (HNB) device is an electronic device that heats an aerosol-generating substrate (treated plant leaf products) without burning it. The heating device heats the aerosol-generating substrate to a high temperature that can generate aerosols but does not reach a point of combustion, allowing the aerosol-generating substrate to generate the aerosol desired by the user, on the premise of non-combustion.

[0003] Currently, non-combustion and heating devices on the market mainly adopt the resistance heating method. That is, the aerosol generating substrate is heated by inserting a central heating tip or a heating needle into the substrate from the center. Such devices require preheating before use, so the waiting time is long and inhalation and stopping cannot be performed freely. In addition, the aerosol generating substrate is unevenly carbonized and the baking of the aerosol generating substrate is insufficient, so the utilization rate is low. In addition, the heating tip of the HNB device is prone to causing dirt on the aerosol generating substrate removal device and the heating tip base, making cleaning difficult. In addition, the temperature of the aerosol generating substrate in the part in contact with the heating element rises too much, causing partial decomposition, which releases substances harmful to the human body. Therefore, instead of the resistance heating method, microwave heating technology is gradually becoming a new heating method. Microwave heating technology has the characteristics of being efficient, rapid, selective and without delay in heating, and has a heating effect only on materials with specific dielectric properties. The application advantages of adopting atomization by microwave heating include the following:

[0004] a. Microwave heating is radiation heating, not thermal conduction, so it is possible to achieve immediate inhalation and immediate stopping.

[0005] b. Since it does not have a heat generating tip, there is no problem with chip breakage or cleaning of the heat generating tip.

[0006] c. The utilization rate of the aerosol-generating substrate is high, and the consistency of the draw is high, resulting in a draw that is more similar to that of a cigarette.

[0007] However, if the microwave device continues to emit microwaves after the hollow body containing the microwave device is opened, there is a risk of harm to people in the vicinity, making it difficult to guarantee safety for users in use. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to solve one of the technical problems existing in the prior art or related art. [Means for solving the problem]

[0009] In view of the above, the present invention provides, in a first aspect, an aerosol generating device. The aerosol generating device includes a housing in which a storage chamber is provided and which can be closed after the storage chamber is opened, a microwave generating device located in the storage chamber and provided with a microwave control circuit, and a first detection member provided in the storage chamber. The first detection member is electrically connected to the microwave control circuit, and when the first detection member detects that the storage chamber has been opened, the microwave control circuit is disconnected.

[0010] In the present invention, when a user wishes to use the aerosol generating device, all that is required is to attach the aerosol substrate to the housing. The microwave generating device is capable of generating microwaves, and when the microwaves act on the aerosol substrate, the aerosol substrate is capable of generating an aerosol. The microwave generating device is mounted within the storage chamber of the housing. Usually, the housing is made of a metal material. Alternatively, a metal coating layer is provided on the inner wall of the housing. This allows the housing to exhibit a shielding effect against microwaves, thereby preventing leakage of microwaves generated by the microwave generating device. The first detection member is mounted within the storage chamber. Since the storage chamber can be opened, the first detection member detects whether the storage chamber is open or not in order to prevent leakage of microwaves. Specifically, the microwave generating device is provided with a microwave control circuit and an execution circuit. Usually, the microwave control circuit is in a connected state, and the execution circuit is Disconnect In this state, the microwave control circuit is in a connected state. When it is desired to apply microwaves to the aerosol substrate to generate an aerosol, the microwave control circuit controls the execution circuit to be connected, so that microwaves can be generated. Since the microwave control circuit is in a connected state, when the storage chamber is opened unintentionally or intentionally, and a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit controls the execution circuit to be connected, and the microwaves generated at this time leak and harm surrounding users. In order to avoid the occurrence of such a situation, when the first detection member detects that the storage chamber has been opened, a detection signal from the first detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. This avoids a situation in which the user is harmed by microwave leakage, and improves the safety of the user when using the aerosol generator.

[0011] Since the first detection member can detect whether the storage chamber is open or not, even if the storage chamber is intentionally opened, the user cannot generate microwaves using the microwave generator, thus preventing the microwaves from being misused.

[0012] In a possible application, cutting off the microwave control circuit means putting the microwave control circuit into a locked state. The locked state means that the circuit is locked, and it is difficult for a general user to unlock the microwave control circuit by his / her own technique. This prevents misuse and also prevents the user from being harmed by microwaves.

[0013] The microwave control circuitry is locked so that unless the microwave control circuitry is unlocked, it will not be activated even if the user closes the chamber again.

[0014] In addition, the aerosol generating device in the above technical solution provided by the present invention may further have the following additional technical features:

[0015] In a possible design, the housing is further provided with a resonant cavity. The microwave generator is used to introduce microwaves into the resonant cavity. The resonant cavity can be opened or closed. The aerosol generator further includes a second detection member located in the resonant cavity. The second detection member is electrically connected to the microwave control circuit. When the second detection member detects that the resonant cavity is opened, the microwave control circuit is disconnected. On the other hand, when the second detection member detects that the resonant cavity is closed, the microwave control circuit is connected.

[0016] In this design, the housing further includes a resonant cavity; Microwave Generator can introduce microwaves into the resonant cavity. A resonant rod is also installed in the housing. The diameter of the resonant rod is smaller than the diameter of the resonant cavity. Therefore, Resonating RodA gap is provided between the outer wall of the resonant cavity and the inner wall of the resonant cavity, and microwaves can be transmitted within the gap. The resonant rod can be a conductor. The resonant rod can be made of a metal material. As an example, the resonant rod is made of copper, aluminum, iron, etc., or alloys thereof. The resonant rod is used to transmit microwaves and improve the transmission speed of microwaves. Since microwaves are less likely to be attenuated during transmission within the resonant cavity, the effect of the microwaves acting on the aerosol-generating substrate is improved. This allows the microwaves to be efficiently and quickly acted on the aerosol-generating substrate, which is advantageous in meeting the usage needs of users.

[0017] In order to ensure the cleanliness of the inside of the resonant cavity, the user can open the resonant cavity to clean the inside of the resonant cavity. Therefore, in order to avoid the problem of microwave leakage when the resonant cavity is opened, a second detection member is installed in the resonant cavity, and the second detection member detects whether the resonant cavity is opened or not. Specifically, when the second detection member detects that the resonant cavity is opened, a detection signal from the second detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate to generate aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. Therefore, a situation in which the user is harmed by microwave leakage is avoided, and the safety of the user when using the aerosol generator is improved. When the user cleans the resonant cavity and closes it, the second detection member detects that the resonant cavity is closed. Then, the second detection member transmits a detection signal to the controller, and the controller controls the microwave control circuit to be connected. In this way, the aerosol generator can generate microwaves based on the needs of the user, and thus avoids the problem of affecting the user's use. The connection and disconnection of the microwave control circuit is related to the open state of the resonant cavity, and thus the aerosol generator can avoid the problem of being unable to continue generating microwaves due to decomposition while ensuring the safety of use.

[0018] The resonant cavity and the containment chamber are two separate cavities.

[0019] In a possible design, the housing includes a first body, a second body removably connected to the first body, the first body and the second body surrounding each other to form a receiving chamber, and at least one of the first body and the second body having a first detection member provided thereon, and a third body removably connected to the first body, the first body and the third body surrounding each other to form a resonant cavity, and at least one of the first body and the third body having a second detection member provided thereon.

[0020] In this design, the second body and the third body are both detachable from the first body. To ensure the cleanliness of the inside of the resonant cavity, the third body is detached from the first body to open the resonant cavity. This is convenient for the user to clean the resonant cavity. When the user detaches the third body from the first body, if the second detection member detects that the resonant cavity is opened, the microwave control circuit is disconnected, so that the user is prevented from being harmed by microwave leakage. After the resonant cavity is cleaned, the third body is attached to the first body. Then, if the second detection member detects that the resonant cavity is closed, the microwave control circuit is connected, so that the microwave generator can generate microwaves normally. This prevents the user from being affected in use.

[0021] Since foreign objects are unlikely to enter the containing chamber, the user does not need to clean the containing chamber. Therefore, it is not recommended that the user disassemble the first body. However, in order to improve convenience when mounting the microwave generator, the first body and the second body are made to have a separate structure, and the second body is mounted on the first body after mounting of the microwave generator is completed. When the user disassembles the third body from the first body, if the second detection member detects that the resonant cavity has been opened, the microwave control circuit is disconnected, thereby preventing the user from being harmed by microwave leakage.

[0022] The first and second bodies may be connected by a locking member such as a screw, or the first and second bodies may be locked by an engagement member. The same applies to the first and third bodies.

[0023] In a possible design, the first detection member includes at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor, and the second detection member includes at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor.

[0024] In this design, the first detection member can be a pressure sensor. For example, the first body and the second body can sandwich the pressure sensor, and when the second body is disassembled, the pressure applied to the pressure sensor is reduced. At this time, the pressure sensor detects that the chamber is opened, and the microwave control circuit is disconnected.

[0025] The first detection member can be a position sensor. As an example, when the second body is attached to the first body, the relative positions of the first body and the second body should not change. On the other hand, when the second body is disassembled, the position sensor detects that the position of the second body has changed. In this case, this means that the storage chamber has been opened, so the microwave control circuit is disconnected.

[0026] The first detection member can be a photoelectric sensor. As an example, the first detection member is an infrared sensor. The infrared sensor determines whether the second body has been disassembled based on the reflected infrared signal. Thereby, when the storage chamber is opened, the microwave control circuit is disconnected.

[0027] The first detection member can be a voltage sensor. As an example, a detection circuit may be installed in the housing. When the second body and the first body are connected, the detection circuit is connected, and when the second body and the first body are separated, the detection circuit is disconnected. When the second body is disassembled, the voltage sensor detects a change in the voltage value of the detection circuit. In this case, this means that the storage chamber has been opened, so the microwave control circuit is disconnected.

[0028] Similar to the first sensing member, the second sensing member may be at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor.

[0029] In a possible design, when the first detection member includes a pressure sensor, the aerosol generating device further includes a first elastic member, the first detection member being provided on one of the first body and the second body, a first end of the first elastic member being connected to the first detection member and a second end of the first elastic member being in contact with the other of the first body and the second body.

[0030] In this design, when the first detection member includes a pressure sensor, it is necessary to determine whether the storage chamber is open or not from the pressure applied to the pressure sensor. As an example, the pressure sensor is attached to the first body. A first elastic member is installed between the pressure sensor and the second body so that the second body can apply pressure to the pressure sensor more accurately. When the second body is attached to the first body, the first elastic member is compressed. At this time, elastic deformation occurs in the first elastic member, and the second body applies force to the pressure sensor through the first elastic member. In addition, when the second body is separated from the first body, the first elastic member returns to its original shape. At this time, the pressure sensor detects a decrease in pressure, and the microwave control circuit is disconnected.

[0031] By providing the first elastic member, it is possible to effectively prevent a situation in which the pressure cannot be detected accurately due to a gap between the second body and the pressure sensor, thereby improving the accuracy in detecting whether the second body has been separated from the first body.

[0032] In other designs, the pressure sensor may be mounted on the second body.

[0033] In a possible design, when the second detection member includes a pressure sensor, the aerosol generating device further includes a second elastic member, the second detection member being provided on one of the first body and the third body, a first end of the second elastic member being connected to the second detection member and a second end of the second elastic member being in contact with the other of the first body and the third body.

[0034] In this design, if the second detection member includes a pressure sensor, it is necessary to determine whether the storage chamber is open or not from the pressure applied to the pressure sensor. As an example, the pressure sensor is attached to the first body. A second elastic member is installed between the pressure sensor and the third body so that the third body can apply pressure to the pressure sensor more accurately. When the third body is attached to the first body, the second elastic member is compressed. At this time, elastic deformation occurs in the second elastic member, and the third body applies force to the pressure sensor through the second elastic member. In addition, when the third body is separated from the first body, the second elastic member returns to its original shape. At this time, the pressure sensor detects a decrease in pressure, and the microwave control circuit is disconnected.

[0035] By providing the second elastic member, the situation in which the pressure cannot be detected accurately due to the presence of a gap between the third body and the pressure sensor can be effectively avoided, thereby improving the accuracy in detecting whether the third body has been separated from the first body.

[0036] In other designs, the pressure sensor may be mounted on a third body.

[0037] In one possible design, the microwave generator includes a microwave emission source located within the chamber, and a microwave introduction portion having a first end that extends into the resonant cavity and a second end that is electrically connected to the microwave emission source.

[0038] In this design, a microwave source can generate microwaves, and the microwaves are introduced into the resonant cavity through a microwave introduction part. The microwave introduction part can change the introduction position of the microwave in the resonant cavity, so as to avoid the components in the resonant cavity and ensure that the microwaves are transmitted stably from the first end of the resonant rod to the second end of the resonant rod.

[0039] In a possible design, where the second detection member includes a voltage sensor, when the voltage sensor detects that the resonant cavity is closed the microwave emission source contacts the microwave introduction portion and when the voltage sensor detects that the resonant cavity is open the microwave emission source is separated from the microwave introduction portion.

[0040] In this design, the microwave emission source and the microwave introduction part are limited to a separate structure. When the microwave emission source and the microwave introduction part contact with each other, the microwave emission source can transmit microwaves to the microwave introduction part, and the microwaves are introduced into the resonant cavity through the microwave introduction part. When the microwave emission source and the microwave introduction part are separated, the microwaves cannot be transmitted to the microwave introduction part. Specifically, when the microwave emission source contacts the microwave introduction part, if the microwave introduction part introduces microwaves into the resonant cavity, the microwave generator can receive a microwave feedback signal. At this time, the voltage sensor can detect a certain value of reverse voltage. When the microwave emission source is separated from the microwave introduction part, the microwave generator cannot receive microwave feedback information, and the reverse voltage detected by the voltage sensor increases. In this case, it means that the resonant cavity is opened, so the microwave control circuit must be disconnected. This improves the accuracy of the detection process.

[0041] The microwave introduction part is attached to the third body, and when the third body is disassembled, the microwave emission source is separated from the microwave introduction part.

[0042] In a possible design, the number of first detection members may be one or more and / or the number of second detection members may be one or more.

[0043] In this design, the number of first detection members may be one. And the first detection member is attached to the first body or the second body. Also, the number of first detection members may be multiple. The multiple first detection members may be attached to the first body. Or the multiple first detection members may be attached to the second body. Or the first detection members may be attached to both the first body and the second body. By increasing the number of first detection members, the accuracy of detecting whether the storage chamber is open or not can be improved, and the microwaves can effectively avoid harming the user.

[0044] The same applies to the second detection member. The number of the second detection members may be one or more.

[0045] In a second aspect, the present invention provides a method for controlling an aerosol generating device. The aerosol generating device includes a housing, a microwave generating device, and a first detection member. The housing is provided with a storage chamber. The microwave generating device is provided within the storage chamber. A microwave control circuit is provided in the microwave generating device, and the microwave control circuit and the first detection member are electrically connected. The control method includes the following. That is, when it is detected from a first detection signal of the first detection member that the storage chamber has been opened, the microwave control circuit is disconnected.

[0046] The first detection member is attached inside the storage chamber. Since the storage chamber can be opened, the first detection member detects whether the storage chamber is open or not in order to prevent microwave leakage. Specifically, the microwave generator is provided with a microwave control circuit and an execution circuit. Usually, the microwave control circuit is in a connected state, and the execution circuit is DisconnectIn this state, the microwave control circuit is in a connected state. When it is desired to apply microwaves to the aerosol substrate to generate an aerosol, the microwave control circuit controls the execution circuit to be connected, so that microwaves can be generated. Since the microwave control circuit is in a connected state, when the storage chamber is opened unintentionally or intentionally, and a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit controls the execution circuit to be connected, and the microwaves generated at this time leak and harm surrounding users. In order to avoid the occurrence of such a situation, when the first detection member detects that the storage chamber has been opened, a detection signal from the first detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. This avoids a situation in which the user is harmed by microwave leakage, and improves the safety of the user when using the aerosol generator.

[0047] Since the first detection member can detect whether the storage chamber is open or not, even if the storage chamber is intentionally opened, the user cannot generate microwaves using the microwave generator, thus preventing the microwaves from being misused.

[0048] In a possible application, cutting off the microwave control circuit means putting the microwave control circuit into a locked state. The locked state means that the circuit is locked, and it is difficult for a general user to unlock the microwave control circuit by his / her own technique. This prevents misuse and also prevents the user from being harmed by microwaves.

[0049] The microwave control circuitry is locked so that unless the microwave control circuitry is unlocked, it will not be activated even if the user closes the chamber again.

[0050] In a possible design, the housing is further provided with a resonant cavity. A microwave generator is used to introduce microwaves into the resonant cavity. The aerosol generating device further includes a second detection member. The second detection member is electrically connected to the microwave generator. The control method further includes: disconnecting the microwave control circuit when the second detection member detects that the resonant cavity is opened, and connecting the microwave control circuit when the second detection member detects that the resonant cavity is closed.

[0051] In this design, in order to ensure the cleanliness of the inside of the resonant cavity, the user can open the resonant cavity to clean the inside of the resonant cavity. Therefore, in order to avoid the problem of microwave leakage when the resonant cavity is opened, a second detection member is installed in the resonant cavity, and the second detection member detects whether the resonant cavity is opened or not. Specifically, when the second detection member detects that the resonant cavity is opened, a detection signal from the second detection member is sent to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves should be applied to the aerosol substrate to generate aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. Therefore, the user is prevented from being harmed by microwave leakage, and the safety of the user when using the aerosol generator is improved. When the user cleans the resonant cavity and closes it, the second detection member detects that the resonant cavity is closed. Then, the second detection member sends a detection signal to the controller, and the controller controls the microwave control circuit to be connected. In this way, the aerosol generator can generate microwaves based on the needs of the user, and thus avoids the problem of affecting the user's use. The connection and disconnection of the microwave control circuit is related to the open state of the resonant cavity, and thus the aerosol generator can avoid the problem of being unable to continue generating microwaves due to decomposition while ensuring the safety of use.

[0052] The resonant cavity and the containment chamber are two separate cavities.

[0053] In a possible design, the second detection member includes a voltage sensor. Also, the microwave generator includes a microwave emission source and a microwave introduction part. When the resonant cavity is opened, the microwave emission source and the microwave introduction part are separated. The control method further includes the following: when the microwave control circuit is disconnected when the second detection member detects that the resonant cavity is opened, the microwave control circuit is controlled to be in a disconnected state when the voltage value detected by the voltage sensor is greater than a predetermined voltage value.

[0054] In this design, the microwave emission source and the microwave introduction part are limited to a separate structure. When the microwave emission source and the microwave introduction part contact with each other, the microwave emission source can transmit microwaves to the microwave introduction part, and the microwaves are introduced into the resonant cavity through the microwave introduction part. When the microwave emission source and the microwave introduction part are separated, the microwaves cannot be transmitted to the microwave introduction part. Specifically, when the microwave emission source contacts the microwave introduction part, if the microwave introduction part introduces microwaves into the resonant cavity, the microwave generator can receive a microwave feedback signal. At this time, the voltage sensor can detect a certain value of reverse voltage. When the microwave emission source is separated from the microwave introduction part, the microwave generator cannot receive microwave feedback information, and the reverse voltage detected by the voltage sensor increases. In this case, it means that the resonant cavity is opened, so the microwave control circuit must be disconnected. This improves the accuracy of the detection process.

[0055] The microwave introduction part is attached to the third body, and when the third body is disassembled, the microwave emission source is separated from the microwave introduction part.

[0056] Additional aspects and advantages of the invention will be set forth in part in the description that follows, and in part will be apparent from, and may be learned by, the practice of the invention.

[0059] In order to make the above objects, features and advantages of the present invention more clearly understandable, the present invention will be described in more detail below in combination with drawings and specific embodiments. It should be noted that, if not inconsistent, the embodiments and features of the present invention may be combined with each other.

[0060] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from those described herein, and therefore the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0061] Hereinafter, an aerosol generating device and a method for controlling the aerosol generating device provided according to some embodiments of the present invention will be described with reference to Figs. 1 to 5.

[0062] As shown in FIG. 1, some embodiments of the present invention provide an aerosol generating device including a housing 100, a microwave generating device 200, and a first detection member 500. The housing 100 is provided with a storage chamber 110. The storage chamber 110 can be closed after being opened. The microwave generating device 200 is located in the storage chamber 110. The microwave generating device 200 is also provided with a microwave control circuit. The first detection member 500 is provided in the storage chamber 110. The first detection member 500 is also electrically connected to the microwave control circuit. When the first detection member 500 detects that the storage chamber 110 has been opened, the microwave control circuit is disconnected.

[0063] In this embodiment, when a user wants to use the aerosol generating device, the user only needs to attach the aerosol substrate 400 to the housing 100. The microwave generating device 200 can generate microwaves, and when the microwaves act on the aerosol substrate 400, the aerosol substrate 400 can generate aerosols. The microwave generating device 200 is mounted in the storage chamber 110 of the housing 100. Usually, the housing 100 is made of a metal material. Alternatively, a metal coating layer is provided on the inner wall of the housing 100. This allows the housing 100 to exhibit a shielding effect against microwaves, thereby preventing leakage of microwaves generated by the microwave generating device. The first detection member 500 is mounted in the storage chamber 110. Since the storage chamber 110 can be opened, the first detection member 500 detects whether the storage chamber 110 is open or not in order to prevent leakage of microwaves. Specifically, a microwave control circuit and an execution circuit are installed in the microwave generating device 200. Normally, the microwave control circuit is connected and the execution circuit is DisconnectIn this state, the microwave control circuit is in a connected state. When it is desired to apply microwaves to the aerosol substrate 400 to generate an aerosol, the microwave control circuit controls the execution circuit to be connected, so that microwaves can be generated. Since the microwave control circuit is in a connected state, when the storage chamber 110 is opened unintentionally or intentionally, and a signal is detected indicating that microwaves are to be applied to the aerosol substrate 400 to generate an aerosol, the microwave control circuit controls the execution circuit to be connected, and the microwaves generated at this time leak and harm surrounding users. In order to avoid the occurrence of such a situation, when the first detection member 500 detects that the storage chamber 110 has been opened, a detection signal from the first detection member 500 is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate 400 to generate an aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that no microwaves are generated. This avoids a situation in which the user is harmed by microwave leakage, and improves the safety of the user when using the aerosol generator.

[0064] Since the first detection member 500 can detect whether the storage chamber 110 is open or not, even if the storage chamber 110 is intentionally opened, the user cannot generate microwaves using the microwave generator, thus preventing the microwaves from being misused.

[0065] In a possible application, cutting off the microwave control circuit means putting the microwave control circuit into a locked state. The locked state means that the circuit is locked, and it is difficult for a general user to unlock the microwave control circuit by his / her own technique. This prevents misuse and also prevents the user from being harmed by microwaves.

[0066] Since the microwave control circuitry is locked, unless the microwave control circuitry is unlocked, the microwave control circuitry will not be activated even if the user closes the containing chamber 110 again.

[0067] In a possible embodiment, the housing 100 is further provided with a resonant cavity 120. The microwave generating device 200 is used to introduce microwaves into the resonant cavity 120. The resonant cavity 120 can be opened and closed. The aerosol generating device further includes a second detection member. The second detection member is located in the resonant cavity 120. The second detection member is electrically connected to the microwave control circuit. When the second detection member detects that the resonant cavity 120 is opened, the microwave control circuit is disconnected. On the other hand, when the second detection member detects that the resonant cavity 120 is closed, the microwave control circuit is connected.

[0068] In this embodiment, the housing 100 further includes a resonant cavity 120. Microwave Generator 200 can introduce microwaves into the resonant cavity 120. A resonant rod 300 is also installed in the housing 100. The diameter of the resonant rod 300 is smaller than the diameter of the resonant cavity 120. Therefore, Resonant Rod 300 A gap is provided between the outer wall of the resonant cavity 120 and the inner wall of the resonant cavity 120, and microwaves can be transmitted through the gap. The resonant rod 300 can be a conductor. The resonant rod 300 can be made of a metal material. For example, the resonant rod 300 is made of copper, aluminum, iron, or an alloy thereof. The resonant rod 300 is used to transmit microwaves and improve the transmission speed of microwaves. Since microwaves are less likely to be attenuated during transmission within the resonant cavity 120, the effect of the microwaves acting on the aerosol-generating substrate is improved. This allows the microwaves to be efficiently and quickly acted on the aerosol-generating substrate, which is advantageous in meeting the usage needs of users.

[0069] In order to ensure the cleanliness of the inside of the resonant cavity 120, the user can open the resonant cavity 120 to clean the inside of the resonant cavity 120. Therefore, in order to avoid the problem of microwave leakage when the resonant cavity 120 is opened, a second detection member is installed in the resonant cavity 120, and the second detection member detects whether the resonant cavity 120 is opened or not. Specifically, when the second detection member detects that the resonant cavity 120 is opened, a detection signal of the second detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate 400 to generate aerosol is detected, the microwave control circuit cannot control to connect the execution circuit, so that microwaves are not generated. Therefore, a situation in which the user is harmed by microwave leakage is avoided, and the safety of the user when using the aerosol generating device is improved. When the user cleans the resonant cavity 120 and closes the resonant cavity 120, the second detection member detects that the resonant cavity 120 is closed. Then, the second detection member transmits a detection signal to the controller, and the controller controls to connect the microwave control circuit. This allows the aerosol generator to generate microwaves based on the needs of the user, and avoids the situation where the aerosol generator affects the user's use. Since the connection and disconnection of the microwave control circuit are related to the open state of the resonant cavity 120, the aerosol generator can avoid the problem of being unable to continue generating microwaves due to disassembly while ensuring safety in use. In addition, the resonant cavity 120 and the storage chamber 110 are two cavities independent of each other.

[0070] In a possible embodiment, the housing 100 includes a first body, a second body, and a third body. The second body is removably connected to the first body. The first body and the second body are arranged to surround each other to form a storage chamber 110, and at least one of the first body and the second body is provided with a first detection member 500. The third body is removably connected to the first body. The first body and the third body are arranged to surround each other to form a resonant cavity 120, and at least one of the first body and the third body is provided with a second detection member.

[0071] In this embodiment, the second body and the third body are both detachable from the first body. In order to ensure the cleanliness of the inside of the resonant cavity 120, the third body is detached from the first body to open the resonant cavity 120. This is convenient for the user to clean the resonant cavity 120. When the user detaches the third body from the first body, if the second detection member detects that the resonant cavity 120 is opened, the microwave control circuit is disconnected, thereby avoiding a situation in which the user is harmed by microwave leakage. In addition, after cleaning the resonant cavity 120, the third body is attached to the first body. Then, if the second detection member detects that the resonant cavity 120 is closed, the microwave control circuit is connected, thereby enabling the microwave generator to generate microwaves normally. This avoids a situation in which the user's use is affected.

[0072] Since foreign matter and the like is unlikely to enter the accommodation chamber 110, the user does not need to clean the accommodation chamber 110. Therefore, it is not recommended that the user disassemble the first main body. However, in order to improve convenience when mounting the microwave generator, the first main body and the second main body are made to have a separate structure, and the second main body is mounted on the first main body after mounting of the microwave generator is completed. When the user disassembles the third main body from the first main body, if the second detection member detects that the resonant cavity 120 has been opened, the microwave control circuit is disconnected, thereby preventing the user from being harmed by microwave leakage.

[0073] The first and second bodies may be connected by a locking member such as a screw, or the first and second bodies may be locked by an engagement member. The same applies to the first and third bodies.

[0074] In a possible embodiment, the first detection member 500 includes at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor, and the second detection member includes at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor.

[0075] In this embodiment, the first detection member 500 can be a pressure sensor. As an example, the first body and the second body can sandwich the pressure sensor, and when the second body is disassembled, the pressure applied to the pressure sensor decreases. At this time, the pressure sensor detects that the accommodation chamber 110 has been opened, and the microwave control circuit is disconnected.

[0076] The first detection member 500 can be a position sensor. As an example, when the second body is attached to the first body, the relative positions of the first body and the second body should not change. On the other hand, when the second body is disassembled, the position sensor detects that the position of the second body has changed. In this case, this means that the storage chamber 110 has been opened, so the microwave control circuit is disconnected.

[0077] The first detection member 500 can be a photoelectric sensor. As an example, the first detection member 500 is an infrared sensor. The infrared sensor determines whether the second body is disassembled based on the reflected infrared signal. Thus, when the storage chamber 110 is opened, the microwave control circuit is disconnected.

[0078] The first detection member 500 may be a voltage sensor. As an example, a detection circuit may be installed in the housing 100. When the second body and the first body are connected, the detection circuit is connected, and when the second body and the first body are separated, the detection circuit is disconnected. When the second body is disassembled, the voltage sensor detects that a change has occurred in the voltage value of the detection circuit. In this case, this means that the accommodation chamber 110 has been opened, so the microwave control circuit is disconnected.

[0079] Similar to the first sensing member 500, the second sensing member may be at least one of a pressure sensor, a position sensor, a photoelectric sensor, and a voltage sensor.

[0080] In a possible embodiment, when the first detection member 500 includes a pressure sensor, the aerosol generating device further includes a first elastic member. The first detection member 500 is provided on one of the first body and the second body. A first end of the first elastic member is connected to the first detection member 500, and a second end of the first elastic member abuts on the other of the first body and the second body.

[0081] In this embodiment, when the first detection member 500 includes a pressure sensor, it is necessary to determine whether the accommodation chamber 110 is open or not from the pressure applied to the pressure sensor. As an example, the pressure sensor is attached to the first body. A first elastic member is installed between the pressure sensor and the second body so that the second body can apply pressure to the pressure sensor more accurately. When the second body is attached to the first body, the first elastic member is compressed. At this time, elastic deformation occurs in the first elastic member, and the second body applies force to the pressure sensor through the first elastic member. In addition, when the second body is separated from the first body, the first elastic member returns to its original shape. At this time, the pressure sensor detects a decrease in pressure, and the microwave control circuit is disconnected.

[0082] By providing the first elastic member, it is possible to effectively prevent a situation in which the pressure cannot be detected accurately due to a gap between the second body and the pressure sensor, thereby improving the accuracy in detecting whether the second body has been separated from the first body.

[0083] In other embodiments, the pressure sensor may be mounted on the second body.

[0084] In a possible embodiment, when the second detection member includes a pressure sensor, the aerosol generating device further includes a second elastic member. The second detection member is provided on one of the first body and the third body. A first end of the second elastic member is connected to the second detection member, and a second end of the second elastic member abuts on the other of the first body and the third body.

[0085] In this embodiment, when the second detection member includes a pressure sensor, it is necessary to determine whether the accommodation chamber 110 is open or not from the pressure applied to the pressure sensor. As an example, the pressure sensor is attached to the first body. A second elastic member is installed between the pressure sensor and the third body so that the third body can apply pressure to the pressure sensor more accurately. When the third body is attached to the first body, the second elastic member is compressed. At this time, elastic deformation occurs in the second elastic member, and the third body applies force to the pressure sensor through the second elastic member. Also, when the third body is separated from the first body, the second elastic member returns to its original shape. At this time, the pressure sensor detects a decrease in pressure, and the microwave control circuit is disconnected.

[0086] By providing the second elastic member, the situation in which the pressure cannot be detected accurately due to the presence of a gap between the third body and the pressure sensor can be effectively avoided, thereby improving the accuracy in detecting whether the third body has been separated from the first body.

[0087] In other embodiments, the pressure sensor may be mounted on a third body.

[0088] Fig. 1 and Fig. 3 In combination, in a possible embodiment, the microwave generating device includes a microwave emission source 210 and a microwave introduction part 220. The microwave emission source 210 is located in the accommodation chamber 110. A first end of the microwave introduction part 220 extends into the resonant cavity 120, and a second end of the microwave introduction part 220 is electrically connected to the microwave emission source 210.

[0089] In this embodiment, the microwave source 210 can generate microwaves, and the microwaves are introduced into the resonant cavity 120 through the microwave introduction part 220. By installing the microwave introduction part 220, the introduction position of the microwave in the resonant cavity 120 can be changed, so that the components in the resonant cavity 120 can be avoided and the microwaves can be stably transmitted from the first end of the resonant rod 300 to the second end of the resonant rod 300.

[0090] 2, 3 and 4, in a possible embodiment, when the second detection member includes a voltage sensor, the microwave emission source 210 contacts the microwave introduction portion 220 when the voltage sensor detects that the resonant cavity 120 is closed, and the microwave emission source 210 separates from the microwave introduction portion 220 when the voltage sensor detects that the resonant cavity 120 is opened.

[0091] In this embodiment, the microwave emission source 210 and the microwave introduction section 220 are limited to a structure of separate bodies. When the microwave emission source 210 and the microwave introduction section 220 come into contact with each other, the microwave emission source 210 can transmit microwaves to the microwave introduction section 220, and introduces the microwaves into the resonant cavity 120 through the microwave introduction section 220. When the microwave emission source 210 and the microwave introduction section 220 are separated from each other, the microwaves cannot be transmitted to the microwave introduction section 220. Specifically, when the microwave emission source 210 comes into contact with the microwave introduction section 220, if the microwave introduction section 220 introduces microwaves into the resonant cavity 120, the microwave generator can receive a feedback signal of the microwaves. At this time, the voltage sensor can detect a certain value of reverse voltage. When the microwave emission source 210 is separated from the microwave introduction section 220, the microwave generator cannot receive the feedback information of the microwaves, and the reverse voltage detected by the voltage sensor increases. In this case, the microwave control circuitry must be disconnected, since this means that the resonant cavity 120 is open, thus improving the accuracy of the detection process.

[0092] The microwave introduction section 220 is attached to the third body, and when the third body is disassembled, the microwave emission source 210 is separated from the microwave introduction section 220.

[0093] In a possible embodiment, the number of first detection members 500 is one or more, and / or the number of second detection members is one or more.

[0094] In this embodiment, the number of the first detection members 500 may be one. And the first detection member 500 is attached to the first body or the second body. Also, the number of the first detection members 500 may be multiple. The multiple first detection members 500 may be attached to the first body. Or the multiple first detection members 500 may be attached to the second body. Or the first detection members 500 may be attached to both the first body and the second body. By increasing the number of the first detection members 500, the accuracy in detecting whether the storage chamber 110 is opened or not can be improved, and the situation in which microwaves harm the user can be effectively avoided.

[0095] The same applies to the second detection member. The number of the second detection members may be one or more.

[0096] Some embodiments of the present invention provide a method for controlling an aerosol generating device. The aerosol generating device includes a housing, a microwave generating device, and a first detection member. The housing is provided with a storage chamber. The microwave generating device is provided in the storage chamber. The microwave generating device is provided with a microwave control circuit, and the microwave control circuit is electrically connected to the first detection member.

[0097] As shown in FIG. 5, the control method for the aerosol generating device includes:

[0098] Step S102: When it is detected from the first detection signal of the first detection member that the containing chamber has been opened, the microwave control circuit is turned off.

[0099] In this embodiment, the first detection member is installed in the storage chamber. Since the storage chamber can be opened, the first detection member detects whether the storage chamber is open or not in order to prevent microwave leakage. Specifically, the microwave generator is provided with a microwave control circuit and an execution circuit. Usually, the microwave control circuit is in a connected state, and the execution circuit is DisconnectIn this state, the microwave control circuit is in a connected state. When it is desired to apply microwaves to the aerosol substrate to generate an aerosol, the microwave control circuit controls the execution circuit to be connected, so that microwaves can be generated. Since the microwave control circuit is in a connected state, when the storage chamber is opened unintentionally or intentionally, and a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit controls the execution circuit to be connected, and the microwaves generated at this time leak and harm surrounding users. In order to avoid the occurrence of such a situation, when the first detection member detects that the storage chamber has been opened, a detection signal from the first detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate to generate an aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. This avoids a situation in which the user is harmed by microwave leakage, and improves the safety of the user when using the aerosol generator.

[0100] Since the first detection member can detect whether the storage chamber is open or not, even if the storage chamber is intentionally opened, the user cannot generate microwaves using the microwave generator, thus preventing the microwaves from being misused.

[0101] In a possible application, cutting off the microwave control circuit means putting the microwave control circuit into a locked state. The locked state means that the circuit is locked, and it is difficult for a general user to unlock the microwave control circuit by his / her own technique. This prevents misuse and also prevents the user from being harmed by microwaves.

[0102] The microwave control circuitry is locked so that unless the microwave control circuitry is unlocked, it will not be activated even if the user closes the chamber again.

[0103] In a possible embodiment, the housing further includes a resonant cavity, the microwave generating device is used to introduce microwaves into the resonant cavity, and the aerosol generating device further includes a second detection member, the second detection member being electrically connected to the microwave generating device.

[0104] The method of controlling the aerosol generating device further includes: disconnecting the microwave control circuit when the second detection member detects that the resonant cavity is opened, and connecting the microwave control circuit when the second detection member detects that the resonant cavity is closed.

[0105] In this embodiment, in order to ensure the cleanliness of the inside of the resonant cavity, the user can open the resonant cavity to clean the inside of the resonant cavity. Therefore, in order to avoid the problem of microwave leakage when the resonant cavity is opened, a second detection member is installed in the resonant cavity, and the second detection member detects whether the resonant cavity is opened or not. Specifically, when the second detection member detects that the resonant cavity is opened, a detection signal from the second detection member is transmitted to the controller, and the controller controls the microwave control circuit to be disconnected. In this case, even if a signal indicating that microwaves are to be applied to the aerosol substrate to generate aerosol is detected, the microwave control circuit cannot control the execution circuit to be connected, so that microwaves are not generated. Therefore, a situation in which the user is harmed by microwave leakage is avoided, and the safety of the user when using the aerosol generator is improved. When the user cleans the resonant cavity and closes it, the second detection member detects that the resonant cavity is closed. Then, the second detection member transmits a detection signal to the controller, and the controller controls the microwave control circuit to be connected. In this way, the aerosol generator can generate microwaves based on the needs of the user, and thus avoids the problem of affecting the user's use. The connection and disconnection of the microwave control circuit is related to the open state of the resonant cavity, and thus the aerosol generator can avoid the problem of being unable to continue generating microwaves due to decomposition while ensuring the safety of use.

[0106] The resonant cavity and the containment chamber are two separate cavities.

[0107] In a possible embodiment, the second detection member comprises a voltage sensor, and the microwave generating device comprises a microwave emission source and a microwave introduction section, and when the resonant cavity is opened, the microwave emission source and the microwave introduction section are separated.

[0108] The method for controlling the aerosol generating device further includes the following: when the microwave control circuit is disconnected when the second detection member detects that the resonant cavity is opened, the microwave control circuit is controlled to be in a disconnected state when the voltage value detected by the voltage sensor is greater than a predetermined voltage value.

[0109] In this embodiment, the microwave emission source and the microwave introduction part are limited to a structure of a separate type. When the microwave emission source and the microwave introduction part come into contact with each other, the microwave emission source can transmit microwaves to the microwave introduction part, and the microwaves are introduced into the resonant cavity through the microwave introduction part. When the microwave emission source and the microwave introduction part are separated, the microwaves cannot be transmitted to the microwave introduction part. Specifically, when the microwave emission source comes into contact with the microwave introduction part and the microwave introduction part introduces microwaves into the resonant cavity, the microwave generator can receive a feedback signal of the microwave. At this time, the voltage sensor can detect a certain value of reverse voltage. When the microwave emission source is separated from the microwave introduction part, the microwave generator cannot receive the feedback information of the microwave, and the reverse voltage detected by the voltage sensor increases. In this case, it means that the resonant cavity is opened, so the microwave control circuit must be disconnected. This improves the accuracy of the detection process.

[0110] The microwave introduction part is attached to the third body, and when the third body is disassembled, the microwave emission source is separated from the microwave introduction part.
