Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the embodiments and the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

As shown in fig. 1, fig. 2, and fig. 3, which are schematic diagrams of an implementation environment of an electronic cigarette 100 according to a preferred embodiment of the present invention. This electron cigarette 100 includes power supply 110 and atomizer 120, and power supply 110 and atomizer 120 connect through removable connection structure. The power supply 110 comprises a casing 111, a rechargeable battery cell 112, a PCBA board 113 and an air duct 115, wherein the rechargeable battery cell 112, the PCBA board 113 and the air duct 115 are arranged in the casing 111; the atomiser 120 comprises a storage chamber 121 for storing a smoking substance, an aerosol generating element 122, a connecting electrode 123 and an airflow channel 124, the aerosol generating element 122 being electrically connected to the connecting electrode 123 for obtaining electrical power, the airflow channel 124 being for the passage of an airflow to carry away the aerosol generated by the aerosol generating element 122 heating the smoking substance for inhalation by a user. When the atomizer 120 is connected to the power supply 110, the airflow passage 124 communicates with the air duct 115 while the electrical connection is completed.

As shown in fig. 2 and 4, the PCBA board 113 is provided with a control circuit 140, and the control circuit 140 includes a controller 141, a voltage stabilizing circuit 142, a signal lamp 143, a push switch 144, a gas pressure switch 145 (a capacitive gas pressure switch or a capacitive proximity switch), a voltage input end 146 (a pin 5 (positive electrode), a pin 2 (negative electrode) of the controller 141 in fig. 4), a capacitor 147, and a voltage output end 148. The air pressure switch 145 is disposed in the air duct 115, so that when the user sucks the electronic cigarette 100, negative pressure is also generated in the air duct 115, and the air pressure switch 145 is triggered, at this time, a capacitance value of the air pressure switch 145 changes. As shown in fig. 5, the push switch 144 is connected in series with the capacitor 147 and then connected in parallel with the pneumatic switch 145 as a branch to form a signal output unit 149, and the signal output unit 149 is electrically connected to a signal input terminal of the controller 141 (pin 1 of the controller 141 in fig. 4) to output a capacitor signal to the controller 141. Signal lamp 143 is electrically connected to control circuit 140 (pin 3 of controller 141 in fig. 4) to emit a light signal. The regulator circuit 142 is provided at a voltage input 146 to stabilize the input voltage of the control circuit 140 (pin 5 of the controller 141 in fig. 4). After the atomizer 120 is connected to the power supply 110, the voltage output 148 is electrically connected to the connecting electrode 123, and at this time, the voltage output 148 can supply power to the aerosol generating element 122 to output an operating voltage to the aerosol generating element 122 (pin 4 of the controller 141 in fig. 4). The controller 141 stores a plurality of instruction codes, and the controller 141 can execute the following steps according to the plurality of instruction codes: a. acquiring a capacitance signal input at pin 1 of the controller 141; b. the output voltage of the voltage output 148 is controlled in accordance with the derived capacitance signal to control the mode of operation of the aerosol generating element 148.

The principle of the signal output unit 149 outputting the capacitance signal is: compared with the case where neither the push switch 144 nor the air pressure switch 145 is activated, when only the push switch 144 is turned on and the air pressure switch 145 is not activated, the capacitance signal received at the pin 1 in the controller 141 is the capacitance value of the capacitor 147; when the push switch 144 is not turned on and the air pressure switch 145 is triggered by negative pressure, the capacitance signal received at the pin 1 in the controller 141 is the capacitance value of the triggered air pressure switch 145; when the push switch 144 is turned on and the air pressure switch 145 is also triggered by negative pressure, the capacitance signal received at the pin 1 of the controller 141 is the capacitance value of the capacitor 147 connected in parallel with the air pressure switch 145. Therefore, by adding a preset value to the controller 141, the controller 141 can output a related command according to the capacitance signal (capacitance value) received at the pin 1.

In the present embodiment, the push switch 144 is a tact switch. In this embodiment, the specific implementation scheme of the step b is only one (the electronic cigarette control circuit is characterized in that the control circuit comprises a voltage input end, a controller, a capacitive air pressure switch, a capacitor, a push switch and a voltage output end, the push switch is connected in series with the capacitor and then connected in parallel with the air pressure switch to form a signal output unit, the signal output unit is electrically connected with the controller to output a capacitor signal to the controller, a plurality of instruction codes are stored in the controller, and the controller can execute the following steps of a, acquiring the input capacitor signal, b, controlling the output voltage of the voltage output end according to the acquired capacitor signal, wherein the cigarette controller 141 is available on the market in a large scale), namely when the capacitor signal is greater than or equal to a set value, the voltage output 148 outputs a constant operating voltage to allow the smoke generating element 122 to operate stably; wherein the set value is greater than or equal to the minimum capacitance value of the air pressure switch 145 and the capacitor 147. The purpose of the arrangement is that on the premise that the habit of sucking the electronic cigarette by a user is not changed, the electronic cigarette 100 can be normally controlled to work no matter the user directly sucks the electronic cigarette or presses the press switch 144 to suck the electronic cigarette; in addition, no matter which of the two branch lines connected in parallel in the signal output unit 149 fails, the control circuit 140 can also stably operate, and the service life of the power supply 110 is prolonged.

Different types of smoking materials are preferred because they may include common tobacco tar, cigarette smoke, low temperature tobacco or hemp oil for medical use. At this time, in other embodiments, the operation mode may further include an operation mode of a square wave voltage curve, an operation mode of a sine wave voltage curve, an operation mode of a constant voltage, and an operation mode of a triangular wave voltage curve. Specifically, a square wave voltage curve working scheme is selected for a power curve corresponding to the working power of the medical hemp oil, a sine wave voltage curve working scheme is selected for a power curve corresponding to the working power of the tobacco paste, a constant voltage working scheme is selected for a power curve corresponding to the working power of the common tobacco oil, and a triangular wave voltage curve working scheme is selected for a power curve corresponding to the working power of the low-temperature tobacco. The operating mode of the low-temperature tobacco and the smoke paste may further include a preheating program (for example, a preheating power smaller than the normal operating power is set), the preheating program is set before the corresponding normal operating power is loaded, and the preheating program is used for preheating the smoke generating substance before the smoke generating element 122 loads the normal operating voltage, so that when a user smokes, the smoke generating element 122 rapidly heats the preheated smoke generating substance after the normal operating power is loaded, and a large amount of smoke is obtained.

Preferably, the constant pressure mode of operation may also include a plurality of constant pressure modes, such as a constant pressure normal mode of operation for preheating the smoking material prior to smoking and a constant pressure preheat mode of operation for high power heating of the smoking material after completion of the preheat mode to enable the preheated smoking material to rapidly generate a large volume of smoke.

Because the push switch 144 and the air pressure switch 145 are low-cost control elements, the push switch 144 and the capacitor 147 are connected in series to form a branch and then connected in parallel with the air pressure switch 145 to form the signal output unit 149, and the controller 141 can control the operation of the smoke generating element 122 according to the capacitance signal by receiving the capacitance signal output by the signal output unit 149, so that the smoke generating device has the advantages of low cost and high practicability. In addition, since the control of the power-on operation of the electronic cigarette 100 by pressing the switch 144 or the air pressure switch 145 is a common control scheme in the field of electronic cigarettes, the use habit of a user, that is, the use experience of the electronic cigarette, is not changed by using the circuit. Finally, the cost is low because the setting procedure in the controller 141 is also not complicated.

In other embodiments, in order to increase the output schemes of multiple capacitance signals, as shown in fig. 6, a capacitive touch switch 116 is further disposed in the control circuit 140', and the touch switch 116 is electrically connected to the capacitance signal input terminal (pin 1) of the controller 141. When the user touches the touch switch 116, the touch switch 116 is connected in parallel to the signal output unit 149. In this case, a capacitor is connected in parallel to the signal output unit 149, i.e. compared with the static state, the present control circuit 140' has 6 combinations of capacitance signals.
