Description

TECHNICAL FIELD

[0001] The disclosure belongs to the field of control of aerosol generating devices, in particular to an aerosol generating device control method and device.

BACKGROUND

[0002] The aerosol generating device usually uses a battery cell with a voltage output of 3.7V, which is stepped down by LDO to 3.3V suitable for the central processor, and directly powers the central processor to ensure that the central processor directly controls the atomizing device to start after receiving the cigarette lighting signal; the cigarette lighting signal is usually sent by the cigarette lighting button of the aerosol generating device under the action of external force.

[0003] In actual use, the aerosol generating device is often placed together with other items due to its small size. When the user is moving, the aerosol generating device is easy to collide with other items. If other items collide with the cigarette lighting button of the aerosol generating device, it is easy to directly cause the battery of the aerosol generating device to power the central processor, thereby controlling the atomizing device to start. However, at this time, it is not during the user's use, and the energy consumption of the central processor power supply and the atomizer start-up at this time is energy waste. Therefore, in actual application, during long-distance transportation or standby transportation, the aerosol generating device is often mistakenly started, resulting in energy waste and even safety hazards, and the energy efficiency of the aerosol generating device is low.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0020] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it can be understood by those of ordinary skill in the art that, in the various implementations of the present invention, numerous technical details have been provided to enable a better understanding of the present application. Nevertheless, the technical solutions claimed by the present application can be implemented even without these technical details and various changes and modifications based on the following implementations.

First Embodiment:

[0021] The first embodiment of the present disclosure provides an aerosol generating device control method, which includes: obtaining a cigarette lighting signal; within a first preset duration, counting a current number of times the cigarette lighting signal is obtained; switching from a standby state to an operating state when the current number of times satisfies a preset number condition.

[0022] In use, the aerosol generating device in this embodiment will enter the normal operating state only if the number of times of lighting a cigarette within the first preset time meets the number condition. This avoids the problem in the prior art that the cigarette lighting key is touched due to accidental collision during transportation or application, thereby generating a single cigarette lighting signal to make the overall application effective. At the same time, in this embodiment, the default state is the standby state, which ensures the effective use of the battery energy in the aerosol generating device.

[0023] The implementation details of the aerosol generating device control method this embodiment are described in detail below. The following contents are only implementation details provided for the convenience of understanding and are not necessary to implement this solution. The specific process of this embodiment is shown in FIG. 1. The embodiment is applied to an aerosol generating device control device.

[0024] Step 101: obtaining the cigarette lighting signal.

[0025] Specifically, the cigarette lighting signal is triggered by the cigarette lighting circuit. A plurality of buttons are provided on the aerosol generating device, one of which corresponds to a switch of the cigarette lighting circuit. When the button is pressed, the cigarette lighting circuit is turned on and the cigarette lighting circuit sends a cigarette lighting signal to the outside. The cigarette lighting signal can be expressed in the form of a high level transmitted by the cigarette lighting circuit, or it can be a data signal sent after the cigarette lighting circuit is turned on.

[0026] Step 102: within a first preset duration, counting a current number of times the cigarette lighting signal is obtained.

[0027] Specifically, the aerosol generating device itself performs timing and counts current number of times the cigarette lighting signal is obtained within a duration. The current number of times identifies the number of times the cigarette lighting signal has been triggered continuously within the preset time period, so that it can be judged whether it has occurred multiple times in a short period of time, and it is convenient to judge whether the subsequent number of times has reached the standard. The first preset time period is usually pre-selected by the user/manufacturer. The timing can start after the power button of the aerosol generating device is activated, or it can start timing from when the cigarette light signal is first received.

[0028] Step 103: switching from a standby state to an operating state when the current number of times satisfies a preset number condition.

[0029] Specifically, the standby state and the operating state of the aerosol generating device are two working processes: in standby state, the power supply connection between the battery circuit and the main control circuit is disconnected; in operating state, the power supply connection between the battery circuit and the main control circuit is connected. When the current number of times satisfies the preset number condition, a battery circuit supplies power to the main control circuit continuously, and when the current number of times is not satisfies the preset number condition, the battery circuit is not supply power continuously to the main control circuit under normal conditions.

[0030] In some embodiments, if the aerosol generating device is in the standby state, when obtaining a cigarette lighting signal, the power supply connection between the battery circuit and the main control circuit is connected for a second preset duration and then disconnected; the second preset time is less than the first preset time.

[0031] The solution adds that in the standby state, the power supply of the main control circuit still depends on the battery circuit, but the battery circuit will not continuously supply power to the main control circuit, the battery circuit will disconnect after the power supply to the main control circuit reaches the second preset time, thereby ensuring that the main control circuit can maintain basic operation, that is, "counting a current number of times the cigarette lighting signal is obtained within the first preset duration" and it is judged that "the current number of times satisfies a preset number condition".

[0032] In some embodiments, switching from the standby state to the operating state when the number of times satisfies the preset number condition, including: obtaining a preset standard number of times; switching the aerosol generating device from the standby state to the operating state when the current number of times is greater than or equal to the standard number of times. Furthermore, the preset standard number of times is stored before obtaining the cigarette lighting signal.

[0033] Further, when the aerosol generating device is in the operating state, the device automatically enters the standby state when no cigarette lighting signal is obtained within a third preset duration, wherein the third preset duration is shorter than the second preset duration. Therefore, it is possible to avoid wasting battery cell energy when the aerosol generating device is not operating, and further improve the utilization rate of battery cell energy.

In specific implementation, the main control circuit 202 changes the connection and disconnection of the switch circuit 203 according to the current number of cigarette lighting signals sent by the cigarette lighting circuit 201 within the first preset duration, thereby adjusting whether the battery circuit 204 supplies power to the main control circuit 202 for a long time through the switch circuit 203.
