The following is a detailed description of specific examples.

Referring to fig. 1 and 2, in one embodiment of the present application, an electronic cigarette control device with a child lock is provided. The apparatus may include:

a main control board 30;

an air flow sensor 10, which is arranged on a main control board 30 and comprises a shell 11, a polar plate 12, a gasket 13, a diaphragm 14 and a PCB (printed circuit board) 15 which are encapsulated in the shell 11, wherein the air flow sensor is used for detecting the suction action;

and an electronic component 20 mounted on the PCB15 for outputting an unlock signal or a lock signal when the detected inhalation is judged to be in compliance.

In some alternative embodiments, the electronic component 20 is specifically configured to: judging whether the duration of the inspiration meets the condition or not, or judging whether the number of inspiration in the set duration meets the condition or not; when the duration exceeds the preset time or the number of times of inspiration exceeds the preset number of times, judging that the conditions are met, and outputting an unlocking signal or a locking signal, wherein the unlocking signal can be used for indicating the work of the heating component of the electronic cigarette, and the locking signal can be used for indicating the non-work of the heating component of the electronic cigarette.

In some alternative embodiments, the electronic component 20 is located within a receiving cavity defined by the PCB15 and the housing 11. That is, the electronic component 20 is mounted on a side surface of the PCB15 facing the inside of the airflow sensor 10, not on a side surface facing the outside. In this way, the electronic component 20 can be better protected and the conductive terminals on the outer side surface of the PCB15 can be easily provided for connection to external devices.

In some alternative embodiments, the apparatus of the present application further comprises: the key switch 40 is electrically connected to the main control board 30, and is electrically connected to the electronic component 20 through the main control board 30; the electronic component 20 is further configured to output an unlock signal or a lock signal when the number of times of the long pressing time or the set time period of the key switch 40 is determined to be in accordance with the condition. The key switch 40 may be a mechanical switch or a touch switch, which is exposed to the housing of the electronic cigarette, so as to be convenient for a user to operate.

In some alternative embodiments, the apparatus of the present application further comprises: the LED lamp 50 is electrically connected to the electronic element 20; the electronic component 20 is also used for controlling the on/off of the LED lamp 50 according to whether the lock is unlocked. Here, the LED lamp 50 may be directly provided on the air flow sensor 10 (in particular, may be provided on the PCB 15), or may be provided on the main control board 30.

the battery assembly 60 is arranged on the main control board 30;

the electronic component 20 is also used for detecting the electric quantity of the battery assembly 60, and controlling the on/off of the LED lamp 50 according to the detected electric quantity.

In some alternative embodiments, no MCU (microprocessor) is provided on the main control board 30. This is because the unlocking/locking functions and the like are already realized by the electronic component 20, and no additional MCU is required.

In some alternative embodiments, the electronic component 20 is also used to convert a change in input voltage into a change in output current; no MOS transistors are provided on the PCB 15. The MOS transistor is a metal oxide semiconductor field effect transistor, and can be used to convert a change of an input voltage into a change of an output current, and since the function can be implemented by the electronic component 20 in the present application, no MOS transistor is required to be disposed in the airflow sensor 10.

The airflow sensor 10 is commonly referred to herein as a microphone, and is typically used as an e-cigarette controller to control the activation or deactivation of the e-cigarette by detecting changes in airflow. The working principle of the device is that the polar plate 12 and the diaphragm 14 form a capacitor, when the suction action is performed, the distance between the polar plate 12 and the diaphragm 14 changes to change the capacitance value, and the voltage at two ends of the base plate 12 and the diaphragm 14 changes due to the fact that the capacitance electric quantity is unchanged.

Here, the electronic component 20 may be a chip, and the corresponding function may be implemented by a writing program, for example, a writing child lock function, which may be implemented using a conventional technology, and the specific implementation thereof is not limited herein.

In some alternative embodiments, a plurality of solder joints may be provided as conductive terminals on an outward facing side surface of the PCB 15. By way of example, the plurality of pads may include three to eight, which may include a power positive terminal, a ground terminal, a signal output terminal, etc., without limitation. In one implementation, 3 welding spots can be provided and connected with the LED lamp; in another implementation, 5 welding spots can be arranged and connected with the LED lamp; in another implementation manner, 6 welding spots can be arranged and are not connected with the LED lamp; in yet another implementation, 5-8 pads may be provided and a patch design may be employed. It is to be understood that the above-described various ways are merely exemplary and are not intended to limit the present application.

As described above, the electronic cigarette controller (i.e. the airflow sensor) is directly integrated with the child lock function by the internal chip, and the internal chip has the child lock function capable of being written. Illustratively, the child lock function has the following modes of implementation:

1. key mode child lock: a long press (freely selected seconds) or a quick press number (freely selected times) can be set for unlocking or locking;

2. smoking mode child lock: the number of consecutive smoke ports (i.e., the number of puffs, which may be freely selected) may be set for a continuous period of smoking (i.e., the duration of the puffs, which may be freely selected) or a fixed period of time (freely selected).

Illustratively, the lock mode is exemplified by:

the smoking function of first power on is normal (be convenient for test shipment, avoid test time to still unblock), even inhale three mouthfuls of locks and do not light, inhale three mouthfuls of unblocks (wherein first two mouthfuls do not light, the third mouthful light 2 seconds but do not export), and the fourth mouthful begins to light and normally export work.

3. Detecting electric quantity, and automatically locking the child lock during charging;

in addition, the chip can also increase the functions of detecting the electric quantity, automatically locking during charging and displaying different lamp colors according to the electric quantity. Illustratively, the microphone has an electrical quantity detection function: 4.2V-3.8V, 3.8V-3.5V, 3.5V-3.1V, and red.

4. Another mode is:

the child lock function is integrated in the electronic component and the mode of implementing the child lock function may also be a curing mode, i.e. not programmable or adjustable after writing. Is not modifiable after the chip fabrication is completed. Exemplary implementations include:

smoking 3 mouths is unlocked within 2S, and normal smoking work can be realized. Alternatively, smoking 3 mouths within 2S locks and stops outputting.

Smoking 2 mouths (or other mouths) within 2S or 3S is unlocked, and standing for 10 minutes or 15 minutes is locked. Etc.
