Detailed Description

The following is further detailed by the specific embodiments:

the first embodiment:

In practice, the user may effect a switch between the two operating modes of the aerosol-generating device by changing the mode adjustment information. In the standby mode, the user can control the atomizer to start, i.e., supply power for the operation of the atomizer, only by satisfying the second manual trigger condition. The aerosol generating device with the microphone and the key multi-triggering mode is avoided, a user cannot adjust the aerosol generating device spontaneously after a certain triggering mode breaks down, and the situation that misjudgment and mistriggering are prone to occurring on the whole aerosol generating device.

The following describes in detail the implementation of the method for controlling an aerosol-generating device according to the present embodiment, and the following description is provided only for the sake of easy understanding and is not essential to the implementation of the present embodiment, and a specific flow of the present embodiment is shown in fig. 1, and the present embodiment is applied to a control device for an aerosol-generating device.

Step 101, acquiring mode adjustment information.

Specifically, the setting of the mode adjustment information may be manually set by a switch, for example, a switch is provided on a battery rod of the aerosol generating device, and different mode adjustment information is selected and transmitted according to the state of the switch for the step 101 to obtain.

In some examples, the switch is one or more keys, and the content of the mode adjustment information is determined by whether the keys are pressed or not, or by a combination of the pressing arrangements of the keys. For example, if the switch is a single key, the mode adjustment information is a if the key is in a normal state, and the mode adjustment information is b if the key is in a pressed state. For example, the switch is a plurality of keys, and whether the keys are pressed down or not and the arrangement and combination of the keys in the pressed state form a plurality of mode adjustment information: n switches, each having m states, the amount of mode adjustment information being

And (4) respectively.

Furthermore, the key can be a mechanical key, a virtual key induced by the display screen, or even a single-pole double-arm switch respectively connected with the two paths.

The structure of the mechanical keys may be as follows: the battery rod battery tail cover of the aerosol generating device comprises a base outer sleeve ring, a pressing moving part, an annular magnet, a plastic matching part, a positioning ring and the like, wherein the pressing moving part is provided with a magnet placing hole and a cylindrical front end, and the plastic matching part is provided with a magnet placing hole and a central hole; after the magnets arranged in the pressing moving part and the magnets arranged in the plastic matching part are respectively magnetized, the N poles of the two magnets are ensured to correspond to the N poles (or the S poles correspond to the S poles), namely, the homopolar correspondence is kept, so that the magnets generate magnetic force with the same poles repelling each other. And after the applied external force is removed, the pressing moving part containing the magnet is pushed back to the original position under the action of the magnetic force of the like charges repelling between the magnets, so that the positive and negative electrodes of the battery are disconnected.

The virtual key of the display screen button can be that the display screen is selected as the touch screen, the bottom of the touch screen is provided with a sensor, the sensor senses which specific site on the display screen is pressed, whether the pressed site is in a range corresponding to the virtual key is judged by combining an area where the virtual key is located, if so, the virtual key of the display screen button is pressed, and if not, the virtual button of the display screen is proved not to be pressed.

The display screen is used for indicating the current working mode of the current aerosol generating device and the selection information in the mode switching process, so that a user can visually know the current working mode through the display screen, and the user can visually judge or select the current working mode through the display screen in the mode switching process conveniently.

In some examples, the switch may also be some rule. I.e., satisfying the rule, mode adjustment information is generated. Such as: obtaining the pressing pressure information, in a preset time length, when the pressing pressure information reaches the preset pressure times and meets the pressing condition, generating corresponding mode adjustment information according to the pressing pressure information, such as: and acquiring pressing pressure information, and generating corresponding mode adjustment information according to the pressing pressure information when the duration of the pressing pressure information reaching the preset pressure meets the pressing condition.

The step of acquiring the pressing pressure information can be the pressure received by the key; the 'preset pressure' in the 'pressing pressure information reaching the preset pressure' is set in advance, so that the step of pressing is intentional, the condition that an article is simply touched is avoided, the corresponding mode adjustment information is also transmitted, and the effectiveness of recognition of the step of pressing is ensured; the pressing condition refers to a standard number of presses.

Taking fig. 2 as an example, the pressing pressure information is the pressure information generated when the circular key is pressed, and the pressure F generated after the circular key is pressed _{Push button} Less than standard pressure F _Sign If so, the press is deemed invalid; pressure F generated after pressing of circular key _{Push button} Greater than or equal to the standard pressure F _Sign It is considered as a valid press. The pressing conditions are set as follows: the number of times of the pressing pressure information reaching the preset pressure reaches 3 times. The corresponding mode adjustment information generated from the compression pressure information is then: the "+" key corresponds to the automatic trigger mode, the "-" key corresponds to the standby mode, that is, the "+" key corresponds to the starting of the automatic trigger mode and the closing of the standby mode, and the "-" key corresponds to the starting of the standby mode and the closing of the automatic trigger mode. Therefore, the circular key continuously presses 3 times to enter a menu interface set in a trigger mode, the plus-minus key can realize state switching, optionally, only one key in the plus-minus key can be set, the state switching can be realized by the key, optionally, the plus-minus key is not set, the state switching is realized by directly utilizing the circular key, and the scheme is not limited.

And 102, adjusting the working mode of the aerosol generating device according to whether the mode adjusting information meets the preset mode switching condition.

In particular, the operating modes include a standby mode and an auto-trigger mode. According to whether the mode adjustment information meets the preset mode switching condition or not, the method comprises the following steps: s2-1, comparing the mode adjustment information with a preset instruction; s2-2, when the mode adjusting information corresponds to the preset instruction, the aerosol generating device is switched from a standby mode to an automatic trigger mode, and otherwise, the aerosol generating device is kept in the standby mode.

In step 101, the acquired mode adjustment information is various, and according to the comparison between the mode adjustment information and the corresponding preset instruction, it is ensured that only the mode adjustment information meeting the preset instruction can perform mode conversion. The preset instruction is preset by a designer or a user.

Step 103, acquiring a trigger signal.

Specifically, the trigger signal is usually set as a trigger signal, and there are two types of trigger signals, one of which is directly input by an input device such as a structural button, a key, a switch, or a wrench, and the other of which is generated by a sensor that automatically monitors an internal state and that generates a trigger signal based on a value detected by the sensor. For example, the trigger signal may be generated by pressing a button on an input device, by a microphone sensor, or by a user client control communicatively coupled to the aerosol generating device. The trigger signal is generated in a variety of forms and is intended to represent the aspiration desired by the user at the time of use.

And 104, controlling the on-off of the atomization device according to whether the trigger signal meets the trigger condition corresponding to the working mode.

Specifically speaking, acquire trigger signal, according to whether trigger signal satisfies the trigger condition that operating mode corresponds, control atomizing device opens and close, include:

under the automatic trigger mode, acquiring a first trigger signal, and if the trigger signal meets a preset automatic trigger condition, controlling the atomization device to start; and/or the presence of a gas in the gas,

under the automatic trigger mode, a second trigger signal is obtained, and if the second trigger signal meets the requirement of a corresponding first manual trigger spring piece, the atomization device is controlled to be started; and/or the presence of a gas in the atmosphere,

and under the standby mode, acquiring a third trigger signal, and controlling the atomization device to start if the third trigger signal meets the requirement of a second manual trigger spring piece corresponding to the standby mode.

Wherein the first trigger signal is generated by automatic detection of a sensor in the aerosol atomizer, for example, the airflow sensing module U16 of the microphone in the control circuit shown in fig. 3 generates the first trigger signal when triggered. The second trigger signal is generated by structure in the aerosol atomizer, for example, when activated by one or more buttons SW1 (as shown in fig. 3), the second trigger signal is generated in an auto-activated state. The third trigger signal is generated by the structure in the aerosol atomizer, e.g. by one or more keys SW1, which generate the third trigger signal in a standby state when triggered. The structure for generating the second trigger signal and the structure for generating the third trigger signal may be the same or different.

In other examples, the method further comprises: and obtaining self-checking information, and switching the aerosol generating device from an automatic trigger mode to a standby mode when the self-checking information reaches a preset emergency condition.

Specifically, the self-test information is information that can be detected by a sensor that performs a self-test in the aerosol generation device, and the emergency condition is set by a user, a worker, or a designer, and is usually set to a range corresponding to a characteristic for determining that the aerosol atomization device has a failure.
