Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment:
a first embodiment of the invention provides an aerosol-generating device control method comprising: acquiring a cigarette lighting signal; counting the current times of the acquired cigarette lighting signals within a first preset time; and when the current frequency information meets a preset frequency condition, switching from a standby state to a working state.
When the cigarette lighter is used, the number of times of lighting in a first preset time period meets the frequency condition, and the cigarette lighter can enter a normal working state. The problem that the cigarette lighting key is touched due to accidental collision during transportation or application in the prior art, and therefore a single cigarette lighting signal is generated to enable the whole application to be effective is solved. Meanwhile, in the scheme, the default state is the standby state, and effective utilization of the cell energy in the aerosol generating device is guaranteed.
The following describes in detail the implementation of the aerosol-generating device control method according to the present embodiment, and the following is 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 an aerosol-generating device control device.
Specifically, the lighting signal is triggered by the lighting circuit. A plurality of keys are arranged on the aerosol generating device, wherein one key corresponds to a switch of the cigarette lighting circuit, when the key is pressed down, the cigarette lighting circuit is conducted, and the cigarette lighting circuit sends a cigarette lighting signal outwards. The expression form of the cigarette lighting signal can be a high level transmitted by the cigarette lighting circuit, or a data signal transmitted after the cigarette lighting circuit is conducted.
And 102, counting the current times of the acquired cigarette lighting signals within a first preset time.
Specifically, the aerosol-generating device itself performs timing and counts information on the current number of detected ignition signals over the period of time. The current frequency information identification is the frequency of the cigarette lighting signal continuously triggered within the preset time, so that whether the cigarette lighting signal appears for a plurality of times in a short time or not can be judged, and whether the follow-up frequency reaches the standard or not can be judged conveniently. The first predetermined period of time is typically a user/manufacturer pre-selected setting and timing may be initiated after activation of a power-on key of the aerosol-generating device or may be initiated when a smoke ignition signal is first received.
And 103, switching from a standby state to a working state when the current frequency information meets a preset frequency condition.
In particular, the standby state and the operating state of the aerosol-generating device are two working processes, in particular: in a standby state, the power supply connection between the battery cell circuit and the main control circuit is disconnected; and under the working state, the power supply connection between the battery cell circuit and the main control circuit is conducted. When the current frequency information meets the preset frequency condition, the battery cell circuit can directly supply power for the main control circuit in the whole process, and when the current frequency information does not meet the preset frequency condition, the battery cell circuit can not continuously supply power for the main control circuit in the conventional state.
In some examples, if the aerosol generating device is in a standby state, when the ignition signal is acquired, the power supply connection between the battery cell circuit and the main control circuit is disconnected after the power supply connection is conducted for a second preset time; the second preset duration is less than the first preset duration.
In the scheme, the power supply of the main control circuit still depends on the battery cell circuit in the standby state, but the battery cell circuit cannot continuously supply power to the main control circuit, and the battery cell circuit is disconnected after the power supply time of the main control circuit reaches the second preset time, so that the main control circuit can maintain basic operation, namely 'counting the current frequency information of the acquired cigarette lighting signal in the first preset time' and judging 'the current frequency information meets the preset frequency condition'.
In some examples, when the number information satisfies a preset number condition, switching from the standby state to the operating state includes: acquiring preset standard frequency information; and when the current time information is greater than or equal to the standard time information, switching the aerosol generation device from a standby state to an operating state. Further, the preset standard times information is stored before the cigarette lighting signal is acquired.
Further, when the aerosol generating device is in a working state and a cigarette lighting signal is not obtained within a third preset time, the aerosol generating device automatically enters a standby state; the third preset time is shorter than the second preset time. Therefore, the waste of the cell energy when the aerosol generating device does not work can be avoided, and the utilization rate of the cell energy is further improved.

In specific implementation, the main control circuit 202 changes the on/off of the switch circuit 203 according to the current times of the cigarette lighting signal sent by the cigarette lighting circuit 201 in a first preset time period, so as to adjust whether the battery cell circuit 204 continuously supplies power to the main control circuit 202 for a long time through the switch circuit 203.
