Description

Aerosol generating device and control method for aerosol generating device

technical field

The present application belongs to the technical field of electronic cigarettes, and in particular, relates to an aerosol generating device and a control method for the aerosol generating device.

Background technique

A heat not burn (Heat Not Burning, HNB) device is an electronic device that heats without burning the aerosol-generating substrate (treated plant leaf products). The heating device heats the aerosol-generating substrate to a temperature at which the aerosol-generating substrate can generate the aerosol but is not high enough to burn through high temperature, so that the aerosol-generating substrate can generate the aerosol required by the user under the premise of not burning.

Heat-not-burn appliances currently on the market mainly adopt resistance heating, that is, use a central heating sheet or a heating needle to insert from the center of the aerosol-generating substrate into the interior of the aerosol-generating substrate for heating. This kind of appliance needs to be preheated for a long time before use, and it cannot be pumped and stopped freely. The carbonization of the aerosol-generating matrix is uneven, resulting in insufficient baking of the aerosol-generating matrix and low utilization rate; Dirt is generated in the matrix extractor and the base of the heating sheet, which is difficult to clean; the local aerosol in contact with the heating element will cause the temperature of the matrix to be too high, and partial cracking will occur, releasing substances harmful to the human body. Therefore, microwave heating technology has gradually replaced resistance heating as a new heating method. Microwave heating technology has the characteristics of high efficiency, timeliness, selectivity and no delay in heating, and it only has a heating effect on substances with specific dielectric properties. The application advantages of using microwave heating atomization are: a. Microwave heating is radiation heating, non-thermal conduction, which can realize immediate pumping and stop; b. There is no heating sheet, so there is no problem of broken pieces and cleaning heating sheets; c. Aerosol generation The matrix utilization rate is high, the taste consistency is high, and the taste is closer to cigarettes.

However, when the cavity loaded with the microwave device is opened, the continuous emission of microwaves by the microwave device may cause harm to surrounding personnel, and it is difficult to guarantee the safety of users.

application content

This application aims to solve one of the technical problems existing in the prior art or related art.

In view of this, the first aspect of the present application proposes an aerosol generating device, including: a housing, the housing is provided with an accommodating cavity, which can be opened and then closed; a microwave generating device is located in the accommodating cavity, and the microwave generates The device is provided with a microwave control circuit; the first detection part is arranged in the accommodating cavity, and the first detection part is electrically connected with the microwave control circuit, and when the first detection part detects that the accommodating cavity is opened, the microwave control circuit is disconnected.

In this application, when the user needs to use the aerosol generating device, the aerosol substrate can be assembled to the housing, and the microwave generating device can generate microwaves. When the microwave acts on the aerosol substrate, the aerosol substrate can generate aerosol. The microwave generating device is installed in the housing cavity, and the housing is usually made of metal material, or the inner wall of the housing is provided with a metal coating, so that the housing can shield the microwave and avoid the microwave generated by the microwave generating device. Microwave leaks. The first detection piece is installed in the accommodating cavity, and the accommodating cavity can be opened. In order to avoid microwave leakage, whether the accommodating cavity is opened is detected by the first detection piece. Specifically, the microwave generating device is provided with a microwave control circuit and an execution circuit. The microwave control circuit is usually in an open state, and the execution circuit is in a short-circuit state. When the accommodating cavity is opened unintentionally or maliciously, since the microwave control circuit is in the access state, if it is detected at this time that the microwave needs to act on the aerosol matrix to generate an aerosol signal, then the microwave control circuit will be activated. It will control the execution circuit path, and the microwave generated at this time will leak and cause harm to surrounding users. To the controller, the controller controls the microwave control circuit to be disconnected. Even if it detects a signal that needs to act on the aerosol matrix through microwaves to generate aerosol at this time, the microwave control circuit cannot control the execution circuit path, so microwaves will not be generated and microwaves will be avoided. Leakage will cause harm to users and improve the safety of users when using the aerosol generating device.

Since the first detection part can detect whether the accommodating cavity is opened, if the accommodating cavity is maliciously opened, the user cannot use the microwave generating device to generate microwaves, so as to avoid malicious use of microwaves.

In a possible application, disconnecting the microwave control circuit means that the microwave control circuit is in a locked state, and the locked state refers to the lock on the circuit. It is difficult for ordinary users to unlock the microwave control circuit through their own technology to avoid malicious The use and avoidance of microwaves may cause harm to users.

Since the microwave control circuit is locked, if the microwave control circuit is not unlocked, the microwave control circuit will not be activated even if the user closes the accommodating cavity again.

In addition, according to the aerosol generating device in the above technical solution provided by the present application, it may also have the following additional technical features:

In a possible design, the shell is also provided with a resonant cavity, and the microwave generating device is used to feed microwaves into the resonant cavity, and the resonant cavity can be opened or closed; the aerosol generating device also includes: a second detection part, located at In the resonant cavity, the second detection part is electrically connected with the microwave control circuit. When the second detection part detects that the resonant cavity is opened, the microwave control circuit is disconnected. When the second detection part detects that the resonant cavity is closed, the microwave control circuit is connected.

In this design, the casing is also provided with a resonant cavity, and the microwave component can feed microwaves into the resonant cavity. A resonant column is arranged inside the shell, and the diameter of the resonant column is smaller than that of the resonant cavity, so there is a gap between the outer wall of the resonant cavity and the inner wall of the resonant cavity, and microwaves can be conducted in this part of the gap. The resonant column can be used as a conductor, and the resonant column can be made of metal material, for example, the resonant column is made of copper, aluminum, iron, etc. or alloys thereof. The resonant column is used to transmit microwaves and increase the microwave transmission rate. When microwaves are transmitted in the resonant cavity, it is not easy to attenuate, and the effect of microwaves acting on the aerosol-generating matrix is improved, so that microwaves can efficiently and quickly act on the aerosol-generating matrix, which is beneficial Meet the needs of users.

In order to ensure the cleanliness of the resonant cavity, the user can open the resonant cavity and clean the inside of the resonant cavity. In order to avoid the problem of microwave leakage when the resonant cavity is opened, a second detection part is installed in the resonant cavity. Whether the resonant cavity is turned on is detected. Specifically, if the second detection part detects that the resonant cavity is opened, the detection signal of the second detection part is sent to the controller, and the controller controls the microwave control circuit to be disconnected, even if it is detected at this time that microwaves need to act on the aerosol matrix to generate For the aerosol signal, the microwave control circuit cannot control the path of the execution circuit, so microwaves will not be generated, preventing the leakage of microwaves from causing harm to the user, and improving the safety of the user when using the aerosol generating device. When the user cleans the resonant cavity and closes the resonant cavity, the second detection part detects that the resonant cavity is closed, and the second detection part sends the detection signal to the controller, and the controller controls the microwave control circuit path so that the aerosol generating device can Microwaves are generated according to the user's needs to avoid affecting the user's use. The on-off of the microwave control circuit is related to the opening state of the resonance cavity. On the basis of ensuring the safety of use, it avoids the problem that the aerosol generating device cannot continue to generate microwaves due to disassembly.

The resonant cavity and the containing cavity are two independent cavities.

In a possible design, the housing includes: a first body; a second body, the second body is detachably connected to the first body, the first body and the second body enclose to form a receiving chamber, the first body and the second body At least one of the two bodies is provided with a first detection member; the third body, the third body is detachably connected to the first body, the first body and the third body are enclosed to form a resonant cavity, the first body and the third body At least one of them is provided with a second detection piece.

In this design, it is limited that the second body and the third body can be detached from the first body. In order to ensure the cleanliness of the resonance cavity, the third body can be detached from the first body, thereby opening the resonance cavity, which is convenient for users to The resonator is cleaned. When the user disassembles the third body from the first body, when the second detection part detects that the resonant cavity is opened, the microwave control circuit is disconnected to avoid damage to the user due to microwave leakage. After the resonant cavity is cleaned, the third body is installed on the first body. When the second detection part detects that the resonant cavity is closed, the microwave control circuit is routed, so that the microwave generating device can generate microwaves normally, so as to avoid affecting the user's use .

Since impurities and the like are not easy to enter the containing chamber, it is not necessary for the user to clean the containing chamber. It is not recommended that the user disassemble the first body, but in order to improve the convenience of installing the microwave generating device, the first body and the second body It is set as a split structure, and after the microwave generating device is installed, the second body is installed on the first body. When the user disassembles the third body from the first body, the second detection part detects that the resonant cavity is opened, and disconnects the microwave control circuit to avoid damage to the user due to microwave leakage.

After the second body is disassembled, the pressure applied to the pressure sensor is reduced. At this time, the pressure sensor detects that the accommodating cavity is opened, and disconnects the microwave control circuit.

The first detection part can be a position sensor. For example, when the second body is installed on the first body, the positions of the first body and the second body should be relatively unchanged. After the second body is disassembled, the position sensor detects If the position of the second body changes, it means that the accommodating cavity is opened at this time, and the microwave control circuit is disconnected.

When the second body is separated from the first body, the detection circuit will be disconnected. , when the second body is disassembled, the voltage sensor acquires a change in the voltage value of the detection circuit, indicating that the accommodating cavity is opened at this time, and the microwave control circuit is disconnected.

Same as the first detecting element, the second detecting element can also be at least one of a pressure sensor, a position sensor, a photoelectric sensor and a voltage sensor.

In a possible design, when the first detection part includes a pressure sensor, the aerosol generating device further includes: a first elastic part; wherein the first detection part is arranged on one of the first body and the second body, The first end of the first elastic member is connected to the first detection member, and the second end of the first elastic member is against the other one of the first body and the second body.

In this design, when the first detection part includes a pressure sensor, it is necessary to judge whether the accommodating cavity is opened by the pressure applied to the pressure sensor. For example, the pressure sensor is installed on the first body, in order to make the second body more Accurately apply pressure to the pressure sensor, and set a first elastic member between the pressure sensor and the second body. When the second body is installed on the first body, the first elastic member is compressed, and at this time, the first elastic member elastically deforms , the second body exerts force on the pressure sensor through the first elastic member. When the second body is separated from the first body, the first elastic member returns to its original deformation. At this time, the pressure sensor detects a drop in pressure and disconnects the microwave control circuit.

By arranging the first elastic member, it is effectively avoided that there is a gap between the second body and the pressure sensor so that the pressure cannot be accurately detected, and the accuracy of detecting whether the second body is separated from the first body is improved.

In other designs, a pressure sensor may also be mounted to the second body.

In this design, when the second detection part includes a pressure sensor, it is necessary to judge whether the accommodating chamber is opened by the pressure applied to the pressure sensor. For example, the pressure sensor is installed on the first body, so that the third body can be more Accurately apply pressure to the pressure sensor, and set a second elastic member between the pressure sensor and the third body. When the third body is installed on the first body, the second elastic member is compressed, and at this time, the second elastic member elastically deforms , the third body exerts force on the pressure sensor through the second elastic member. When the third body is separated from the first body, the second elastic member returns to its original deformation. At this time, the pressure sensor detects a drop in pressure and disconnects the microwave control circuit.

By arranging the second elastic member, it is effectively avoided that there is a gap between the third body and the pressure sensor and the pressure cannot be accurately detected, and the accuracy of detecting whether the third body is separated from the first body is improved.

In other designs, a pressure sensor may also be mounted to the third body.

In a possible design, the microwave generating device includes: a microwave emission source, located in the containing cavity; a microwave introduction part, the first end of the microwave introduction part extends into the resonant cavity, and the second end of the microwave introduction part is electrically connected to the microwave emission source. connect.

By setting the microwave introduction part, the introduction position of the microwave in the resonant cavity can be changed, and the components in the resonant cavity can be avoided. , it can also ensure that the microwave is stably transmitted from the first end of the resonant column to the second end of the resonant column.

In a possible design, based on the fact that the second detection part includes a voltage sensor, when the voltage sensor detects that the resonant cavity is closed, the microwave emission source is in contact with the microwave introduction part, and when the voltage sensor detects that the resonant cavity is opened , the microwave emission source is separated from the microwave introduction part.

In this design, the microwave emission source and the microwave introduction part are limited to a split structure. When the microwave emission source and the microwave introduction part are in contact, the microwave emission source can transmit the microwave to the microwave introduction part, and the microwave can be introduced into the microwave through the microwave introduction part. into the resonant cavity. When the microwave emission source is separated from the microwave introduction part, the microwave cannot be transmitted to the microwave introduction part. Specifically, when the microwave emission source is in contact with the microwave introduction part, when the microwave introduction part guides the microwave into the resonant cavity, the microwave generating device can receive the feedback signal of the microwave, and the voltage sensor can detect a certain value of reverse voltage at this time, When the microwave emission source is separated from the microwave introduction part, the microwave generating device cannot receive the microwave feedback information at this time, and the reverse voltage detected by the voltage sensor increases, indicating that the resonant cavity is opened at this time, and the microwave control circuit needs to be disconnected. Improve the accuracy of the detection process.

The microwave introduction part is installed on the third body, and when the third body is disassembled, the microwave emission source is separated from the microwave introduction part.

In a possible design, there are one or more first detecting elements; and/or one or more second detecting elements.

In this design, the number of the first detection part may be the first, and the first detection part is installed on the first body or the second body. There can also be a plurality of first detection parts, and a plurality of first detection parts can be installed on the first body, or a plurality of first detection parts can be installed on the second body, or both the first body and the second body can be installed with The first detection piece.

The control method includes: when the first detection signal of the first detection part detects that the accommodating cavity is opened, the microwave control circuit is disconnected.

The first detection piece is installed in the accommodating cavity, and the accommodating cavity can be opened. In order to avoid microwave leakage, whether the accommodating cavity is opened is detected by the first detection piece. Specifically, the microwave generating device is provided with a microwave control circuit and an execution circuit. The microwave control circuit is usually in an open state, and the execution circuit is in a short-circuit state. When the accommodating cavity is opened unintentionally or maliciously, since the microwave control circuit is in the access state, if it is detected at this time that the microwave needs to act on the aerosol matrix to generate an aerosol signal, then the microwave control circuit will be activated. It will control the execution circuit path, and the microwave generated at this time will leak and cause harm to surrounding users. To the controller, the controller controls the microwave control circuit to be disconnected. Even if it detects a signal that needs to act on the aerosol matrix through microwaves to generate aerosol at this time, the microwave control circuit cannot control the execution circuit path, so microwaves will not be generated and microwaves will be avoided.

Detailed ways

In order to better understand the above-mentioned purpose, features and advantages of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In the following description, many specific details are set forth in order to fully understand the application, but the application can also be implemented in other ways different from those described here, therefore, the protection scope of the application is not limited by the specific details disclosed below. EXAMPLE LIMITATIONS.

The aerosol generating device and the control method of the aerosol generating device provided according to some embodiments of the present application are described below with reference to FIGS. 1 to 5 .

As shown in FIG. 1 , in some embodiments of the present application, an aerosol generating device is proposed, including: a housing 100 , a microwave generating device 200 and a first detection part 500 , the housing 100 is provided with an accommodating cavity 110 , The accommodating chamber 110 can be opened and then closed; the microwave generating device 200 is located in the accommodating chamber 110, and the microwave generating device 200 is provided with a microwave control circuit; When the first detection part 500 detects that the accommodating cavity 110 is opened, it disconnects the microwave control circuit.

In this embodiment, when the user needs to use the aerosol generating device, the aerosol base 400 can be assembled to the housing 100, the microwave generating device 200 can generate microwaves, and when the microwave acts on the aerosol base 400, the aerosol base 400 can generate aerosol. The microwave generating device 200 is installed in the housing cavity 110 of the housing 100. The housing 100 is usually made of a metal material, or the inner wall of the housing 100 is provided with a metal coating, so that the housing 100 can shield microwaves. Avoid leakage of microwaves generated by microwave generators. The first detection part 500 is installed in the accommodating cavity 110 , and the accommodating cavity 110 can be opened. In order to avoid microwave leakage, whether the accommodating cavity 110 is opened is detected by the first detecting part 500 . Specifically, the microwave generating device 200 is provided with a microwave control circuit and an execution circuit. The microwave control circuit is usually in an open state, and the execution circuit is in a short-circuit state. Execute the circuit path, so as to be able to generate microwaves. When the accommodating cavity 110 is opened unintentionally or maliciously, since the microwave control circuit is in the path state, if it is detected at this time that the microwave needs to act on the aerosol matrix 400 to generate an aerosol signal, then The microwave control circuit will control the path of the execution circuit, and the microwave generated at this time will leak, causing harm to surrounding users. The detection signal of the detection part 500 is sent to the controller, and the controller controls the microwave control circuit to be disconnected. Even if it is detected at this time that the aerosol signal needs to be generated by the microwave acting on the aerosol matrix 400, the microwave control circuit cannot control the execution circuit path. Therefore, microwaves will not be generated, avoiding damage to users caused by microwave leakage, and improving the safety of users when using the aerosol generating device.

The housing 100 is provided with a resonance column 300, the diameter of the resonance column 300 is smaller than the diameter of the resonant cavity 120, so there is a gap between the outer wall of the resonant cavity 120 and the inner wall of the resonant cavity 120, and microwaves can be conducted in this part of the gap . The resonant column 300 can be used as a conductor, and the resonant column 300 can be made of metal material. Exemplarily, the resonant column 300 is made of copper, aluminum, iron, etc. or alloys thereof. The resonant column 300 is used to transmit microwaves and increase the microwave transmission rate.

It is beneficial to meet the needs of users.

In order to ensure the cleanliness of the resonant cavity 120, the user can open the resonant cavity 120 and clean the inside of the resonant cavity 120. In order to avoid the problem of microwave leakage when the resonant cavity 120 is opened, a second detection piece is installed in the resonant cavity 120. The second detecting element detects whether the resonant cavity 120 is turned on. Specifically, if the second detection part detects that the resonant cavity 120 is opened, the detection signal of the second detection part is sent to the controller, and the controller controls the microwave control circuit to be disconnected, even if it is detected that the aerosol matrix 400 needs to be acted on by microwaves. For the aerosol-generating signal, the microwave control circuit cannot control the path of the execution circuit, so no microwave is generated, which prevents the leakage of microwave from causing harm to the user, and improves the safety of the user when using the aerosol generating device. When the user cleans the resonant cavity 120 and closes the resonant cavity 120, the second detection part detects that the resonant cavity 120 is closed, and the second detection part sends the detection signal to the controller, and the controller controls the microwave control circuit path, so that the aerosol generating device Microwaves can be generated according to the needs of users to avoid affecting the use of users. The on-off of the microwave control circuit is related to the opening state of the resonant cavity 120. On the basis of ensuring the safety of use, the problem that the aerosol generating device cannot continue to generate microwaves due to disassembly is avoided. The resonance cavity 120 and the accommodation cavity 110 are two independent cavities.

When the user disassembles the third body from the first body, when the second detection part detects that the resonant cavity 120 is opened, the microwave control circuit is disconnected to avoid damage to the user due to microwave leakage. After the resonant cavity 120 is cleaned, the third body is installed on the first body. When the second detection part detects that the resonant cavity 120 is closed, the microwave control circuit is routed so that the microwave generating device can generate microwaves normally, avoiding the use of the user. make an impact.

Since impurities and the like are not easy to enter the receiving chamber 110, it is not necessary for the user to clean the receiving chamber 110. It is not recommended that the user disassemble the first body, but in order to improve the convenience of installing the microwave generating device, the first body and the second body The second body is set as a split structure, and after the microwave generating device is installed, the second body is installed on the first body. When the user disassembles the third body from the first body, the second detection element detects that the resonant cavity 120 is opened, and disconnects the microwave control circuit to avoid damage to the user due to microwave leakage.

In a possible embodiment, the first detection part 500 includes: at least one of a pressure sensor, a position sensor, a photoelectric sensor and a voltage sensor; the second detection part includes: a pressure sensor, a position sensor, a photoelectric sensor and a voltage sensor at least one of the

In this embodiment, the first detection member 500 may be a pressure sensor. For example, the first body and the second body may clamp the pressure sensor. After the second body is disassembled, the pressure applied to the pressure sensor is reduced. At this time, the pressure sensor detects that the accommodating cavity 110 is opened, and disconnects the microwave control circuit.
