The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Example one
The present disclosure provides a battery circuit, as shown in fig. 1, the battery circuit includes at least two battery slots 1, at least two electronically controlled battery switches 2, an electronically controlled main switch 3, a power supply output port 4, and a controller 5, wherein: each battery jar 1, the electric control main switch 3 and the power supply output port 4 are connected in series; each electric control battery switch 2 is respectively connected with one battery jar 1 in parallel, and the control end of each electric control battery switch 2 is respectively electrically connected with the controller 5; the control end of the electric control main switch 3 is electrically connected with the controller 5; the positive electrode of each battery jar 1 is electrically connected with the controller 5.
The battery circuit is applied to a battery device of the electronic cigarette, the battery device is a power supply control component of the electronic cigarette, as shown in fig. 2, the electronic cigarette generally further includes an atomizer 6, the atomizer 6 is a component capable of atomizing the smoke oil stored therein to form smoke, and the battery device is used for supplying operating voltage to the atomizer 6. The battery container 1 is a container for mounting a battery and electrically connecting the battery with a battery circuit of a battery device. The electric control battery switch 2 and the electric control main switch 3 are both switches that control the on and off of the circuit in which the electric control battery switch is located through electric signals, and can be Metal-Oxide-Semiconductor field effect transistors (MOS), relays, chips, or the like. The power supply output port 4 is a voltage output port, and the battery device supplies an operating voltage to the atomizer 6 through the power supply output port 4 so that the atomizer 6 operates normally. The controller 5 is a component for controlling each component of the battery device, such as a Micro Control Unit (MCU), and the controller 5 is electrically connected to some components of the battery device to control the operation of each component.
In implementation, as shown in fig. 1, each battery container 1 is connected in parallel with one electrically controlled battery switch 2, when the electrically controlled battery switch 2 is closed, the battery container 1 connected in parallel with the electrically controlled battery switch is short-circuited, and when the electrically controlled battery switch 2 is opened, the battery container 1 connected in parallel with the electrically controlled battery switch can be connected in series to work in a circuit. The positive electrode of each battery well 1 is electrically connected to the controller 5, so that the controller 5 can detect the voltage of the battery loaded in the battery well 1, and thus determine the remaining capacity of the battery loaded in the battery well 1, as will be described below. The control end of the electric control battery switch 2 is connected with the controller 5, so that the controller 5 can control the on and off of the electric control battery switch 2 through electric signals. Each battery jar 1, the electric control main switch 3 and the power supply output port 4 are connected in series, the electric control main switch 3 is arranged on a circuit between each battery jar 1 and the power supply output port 4, the electric control main switch 3 is used as a main switch of all battery jars 1 of the battery device, when the electric control main switch 3 is closed, the battery device can convey working voltage to the atomizer 6, and when the electric control main switch 3 is disconnected, the battery device stops conveying the working voltage to the atomizer 6. The control end of the electric control main switch 3 is electrically connected with the controller 5, so that the controller 5 can control the on and off of the electric control main switch 3 through electric signals.
It should be noted that there is a proportional relationship between the voltage of the battery and the charge of the battery, and the more sufficient the charge of the battery, the higher the voltage of the corresponding battery. The preset voltage threshold is a voltage corresponding to a condition that the battery is particularly low in power, and when the voltage of the battery is smaller than the preset voltage threshold, the battery is considered to be incapable of providing the working voltage to the atomizer 6.
The number of the battery containers 1 can be arbitrarily set according to requirements, for example, as shown in fig. 1, the number of the battery containers 1 can be set to three, and the relationship between the batteries in series is described in detail below by taking three battery containers 1 as an example:
for convenience, the batteries mounted in the three battery containers 1 may be numbered, and as shown in fig. 1, they are respectively referred to as a battery a, a battery B, and a battery C. The negative electrode of the battery A is grounded, the negative electrode of the battery B is connected with the positive electrode of the battery A, the negative electrode of the battery C is connected with the positive electrode of the battery B, and the three batteries are connected in series.
As shown in fig. 1, a battery a, a battery B, a battery C, an electronically controlled main switch 3 and a power supply output port 4 are connected in series, wherein the battery a is connected in parallel with an electronically controlled battery switch 2, the battery B is connected in parallel with an electronically controlled battery switch 2, and the battery C is connected in parallel with an electronically controlled battery switch 2.
The controller 5 is electrically connected to the positive electrode of each battery container 1, and can detect the voltage value of the battery in each battery container 1, wherein the principle of the controller 5 detecting the voltage may be as follows:
the controller 5 detects that the voltage at the positive pole of the battery a is the voltage of the battery a (since the negative pole of the battery a is grounded, the voltage at the negative pole is zero). The battery detects that the voltage at the positive pole of battery B minus the voltage of battery A is the voltage of battery B. The voltage of the battery C is obtained by subtracting the voltages of the battery A and the battery B from the voltage detected by the battery C.
Therefore, the controller 5 can detect a voltage change of the battery in each battery slot 1 and then make a corresponding process based on the voltage change. For example, when a battery is installed in a certain battery jar 1, the controller 5 detects that the voltage in the battery jar 1 becomes large, and further can detect that the voltage in the battery jar 1 is greater than the preset voltage threshold, the controller 5 controls the electrically controlled battery switch connected in parallel with the battery jar 1 to be turned off, and the battery jar 1 is connected to the circuit, so that the battery in the battery jar 1 provides the operating voltage for the atomizer 6. When the battery device works, the controller 5 detects that the voltage of the battery in a certain battery jar 1 is not greater than a preset voltage threshold (possibly because the electric quantity is very low, or because the battery jar is in poor contact with the battery, or because the battery is not installed), the controller 5 controls the electrically controlled battery switch 2 connected with the battery jar 1 in parallel to be closed, the battery jar 1 is short-circuited, and the work is stopped.
Thus, each battery jar 1 is connected in parallel with an electrically controlled battery switch 2, and when the electric quantity of the battery in any battery jar 1 is not greater than the preset voltage threshold, the controller 5 controls the electrically controlled battery switch 2 connected in parallel with the battery jar 1 to be closed, so as to short circuit the battery jar 1. The battery jar 1 is short-circuited, so that the work of other battery jars 1 in the battery device is not influenced, the battery device works normally, and the electronic cigarette also works normally.
In the embodiment of the present disclosure, each battery jar in the battery circuit is connected in parallel with an electrically controlled battery switch, and when the electric quantity of the battery in any one of the battery jars is very low, or the contact between any one of the battery jars and the battery is poor, or there is no battery in any one of the battery jars, the controller controls the electrically controlled battery switch connected in parallel with the battery jar to be closed, so as to short-circuit the battery jar. As long as a battery capable of working is arranged in one battery groove, the battery circuit can work normally, and therefore the electronic cigarette can work normally.
Example two
The disclosure also provides a battery device, which includes the battery circuit described in the first embodiment, and as described in the first embodiment, each battery jar in the battery circuit is connected in parallel with an electronically controlled battery switch, and when the electric quantity of the battery in any one of the battery jars is very low, or the contact between any one of the battery jars and the battery is poor, or there is no battery in any one of the battery jars, the controller controls the electronically controlled battery switch connected in parallel with the battery jar to close, so as to short-circuit the battery jar. As long as a battery capable of working is arranged in one battery groove, the battery device can work normally, and therefore the electronic cigarette can work normally.
EXAMPLE III
The present disclosure provides an electronic cigarette, which includes an atomizer 6 and the battery device described in the first embodiment, and the battery device supplies an operating voltage to the atomizer 6 through a power supply output port to operate the atomizer 6. The battery device is as in the first embodiment, each battery jar in the battery device is connected in parallel with an electrically controlled battery switch, and when the electric quantity of the battery in any one of the battery jars is very low or the contact between any one of the battery jars and the battery is poor or the battery is not in any one of the battery jars, the controller controls the electrically controlled battery switch connected in parallel with the battery jar to be closed to short-circuit the battery jar. The battery device can work normally as long as a battery capable of working is placed in one battery groove, so that the electronic cigarette can work normally.
Example four
The embodiment of the present disclosure provides a power supply control method for an electronic cigarette, which may be applied to a battery circuit in the first embodiment, a battery device in the second embodiment, and an electronic cigarette in the third embodiment, as shown in fig. 3, a processing flow of the method may include the following steps:
in step 301, the controller 5 determines, among the plurality of battery slots 1, a battery slot 1 whose current voltage is greater than a preset voltage threshold.
As described in the first embodiment, the preset voltage threshold is a voltage corresponding to a battery with a particularly low battery level, and when the voltage of the battery is smaller than the preset voltage threshold, it may be considered that the battery cannot provide the operating voltage to the atomizer 6, that is, the voltage of the battery is not sufficient to support the operation of the atomizer 6.
Optionally, a certain trigger event may be set for step 301, and correspondingly, the processing of step 301 may be as follows: when the controller 5 detects that a battery is loaded into any one of the battery slots 1, or reaches a preset detection period, the controller 5 determines, among the plurality of battery slots 1, the battery slot 1 in which the current voltage of the battery is greater than a preset voltage threshold.
The controller 5 detects the voltage in the battery jar according to the principle of detecting the voltage described in the first embodiment.
In implementation, when a user installs a battery in any one of the battery slots 1, first, the controller 5 may detect the installation of a new battery according to a voltage change of the battery device, the installation of the new battery may trigger the controller 5 to detect the voltage in each battery slot 1, then, the controller 5 detects the voltage of the battery in each battery slot 1, and finally, determines the battery slot 1 of which the current voltage is greater than the preset voltage threshold. Or, in the operation of the battery device, when a preset detection period is reached, first, the controller 5 is triggered to detect the voltage in each battery jar 1, then, the controller 5 detects the voltage of the battery in each battery jar 1, and finally, the battery jar 1 with the current voltage greater than the preset voltage threshold is determined. The preset detection period may be every 30 seconds, 1 minute, two minutes, and the like, which is not limited in this embodiment.
In implementation, after determining that the current voltage of the battery jar 1 is greater than the preset voltage threshold, the controller 5 sends an off electrical signal to the electronically controlled battery switch 2 connected in parallel to such battery jar 1, and the electronically controlled battery switch 2 is turned off after receiving the electrical signal, so that such battery jar 1 can deliver the operating voltage to the atomizer 6 through the power supply output port 4. After the controller 5 determines that the current voltage of the battery jar 1 is not greater than the preset voltage threshold, the controller sends a closed electric signal to the electronic control battery switch 2 connected in parallel with the battery jar 1, and the electronic control battery switch 2 is closed after receiving the electric signal, so that the battery jar 1 is short-circuited, and the battery jar 1 stops supplying the working voltage to the atomizer 6.
It should be noted that, when a battery is not installed in one or more battery containers 1 or the battery is in poor contact with the battery, the controller 5 detects that the voltage in such battery container 1 is zero, and such battery container 1 also belongs to the battery container 1 whose current voltage is not greater than the preset voltage threshold.
Based on the above, when the method is used to control the battery device to operate, and when the electric quantity of the battery in any battery slot 1 of the battery device is very low (i.e. the voltage is less than the preset voltage threshold), or the contact between any battery slot 1 and the battery is poor, or there is no battery in any battery slot, the controller 5 sends a closed electrical signal to the electronically controlled battery switch 2 connected in parallel with the battery slot 1, and the electronically controlled battery switch 2 is closed, so as to short-circuit the battery slot 1. As long as a battery with voltage larger than a preset voltage threshold value exists in one battery slot 1, the battery device can work normally, and the electronic cigarette can work normally.
In implementation, the controller 5 controls the electrically controlled main switch 3 to be turned on, and two cases can be divided into the first case: when a user uses the electronic cigarette to smoke, as long as the controller 5 detects that the battery jar 1 with the current voltage larger than the preset voltage threshold exists in the battery device, the controller 5 sends a closed electric signal to the electric control main switch 3, and the electric control main switch 3 is closed after receiving the electric signal, so that a circuit between the battery jar 1 and the power supply output port 4 is conducted, and therefore a battery in the battery device can provide working voltage for the atomizer 6. In the second case: when a user uses the electronic cigarette to smoke, under the condition that the controller 5 detects that the battery jar 1 with the current voltage larger than the preset voltage threshold exists in the battery device, the user can send an operation signal to the controller 3 in a mode of continuously pressing a power key and the like, and the controller 3 controls the electric control main switch 3 to be switched on after receiving the operation signal, so that the battery in the battery device can provide working voltage for the atomizer 6.
Alternatively, the controller 5 may adjust the operation modes of different output powers based on the number of currently available batteries in the battery device, and the corresponding process may be as shown in fig. 4, and includes the following steps:
Wherein the number of battery slots 1 having a voltage greater than a preset voltage threshold may be considered as the number of available batteries in the battery device. The correspondence between the operating mode and the number of available batteries prestored in the controller 5 is: as shown in table 1, when there is an available battery in the battery device, the output power of the battery device in the power saving mode is minimum, for example, 5 watts; when there are two available batteries in the battery device, corresponding to the low power mode, the output power of the battery device in the low power mode is slightly larger, for example, 10 watts; when there are three available batteries in the battery device, the output power of the battery device in the high power mode is maximum, which may be 20 watts, for example. The user may also select the mode of operation of the e-cigarette by himself, as will be described in more detail below.
TABLE 1
| Number of available batteries | Mode of |
| 1 | |
| 2 | |
| 3 | High power mode |
In implementation, the controller 5 may count the number of battery slots 1 of which the current voltage is greater than the preset voltage threshold after determining the battery slots 1 of which the current voltage is greater than the preset voltage threshold. Further, the operation modes (i.e., the first operation modes) corresponding to the number can be searched in the correspondence table.
At step 402, the controller 5 sets the operation mode to the first operation mode.
A power regulating circuit 7 is arranged on a circuit between the electric control main switch 3 and the power supply output port 4, and the power regulating circuit 7 can regulate the output power of the battery device to the atomizer 6 under the control of the controller 5.
In operation, after the controller 5 determines the first mode of operation, it sends a power adjustment signal corresponding to the first mode of operation to the power adjustment circuit 7. After the power adjusting circuit 7 receives the power adjusting signal, parameters of circuit elements are adjusted to enable the output power of the battery device to be a power value corresponding to the first working mode, and then the electronic cigarette enters the first working mode to work. For example, when the controller 5 determines that the operating mode is the power saving mode according to the correspondence relationship in table 1, it sends a power adjustment signal corresponding to the power saving mode to the power adjustment circuit 7; after receiving the power adjustment signal, the power adjustment circuit 7 adjusts the output power of the circuit to 5 watts, so that the electronic cigarette operates in a power saving mode. For another example, when the controller 5 determines that the operation mode is the low power mode according to the correspondence relationship in table 1, it sends a power adjustment signal corresponding to the low power mode to the power adjustment circuit 7; after receiving the power adjustment signal, the power adjustment circuit 7 adjusts the output power of the circuit to 10 watts, so that the electronic cigarette operates in a low power mode. For another example, when the controller 5 determines that the operation mode is the high power mode according to the correspondence in table 1, it sends a power adjustment signal corresponding to the high power mode to the power adjustment circuit 7; after receiving the power adjustment signal, the power adjustment circuit 7 adjusts the output power of the circuit to 20 w, so that the electronic cigarette operates in a high power mode.
Based on the above, the controller 5 may control the electronic cigarette to automatically switch among the three operation modes according to the number of the currently available batteries.
Optionally, the user may manually select the operation mode, and the corresponding processing may be: when receiving a mode switching instruction input by a user, the controller 5 sets the operating mode to a third operating mode corresponding to the mode switching instruction.
The shell of the battery device is provided with an electronic display screen, and an interface with a mode switching function is arranged for displaying and selecting working modes. The controller 5 may also control the operation mode of displaying different output powers in the electronic display screen based on the number of currently available batteries in the battery device, and the corresponding process may be:
first, the controller 5 determines a first operating mode corresponding to the number of currently available batteries and an operating mode with output power lower than that of the first operating mode according to a pre-stored correspondence relationship between the operating mode and the number of available batteries, where the first operating mode and the operating mode with output power lower than that of the first operating mode may be referred to as an optional operating mode. The controller 5 then sets the status of the selectable operating modes on the electronic display screen to a selectable status.
Based on the correspondence between the number of available batteries and the operation mode in table 1, the correspondence between the number of available batteries and the selectable operation mode may be: as shown in table 2, when the number of available batteries is one, the operation mode can be selected as the power saving mode; when the number of the available batteries is two, the working mode can be selected to be a power saving mode and a low power mode; when the number of the available batteries is three, the selectable working modes are a power saving mode, a low power mode and a high power mode.
TABLE 2
| Number of available batteries | |
| 1 | |
| 2 | Low power mode, |
| 3 | High power mode, low power mode, power saving mode |
In this way, the user selects the operation mode of the electronic cigarette through a touch screen or a key based on the selectable operation modes displayed on the electronic display screen. In the following, an example is described in which three available batteries are present in the battery device, and the user selects the operation mode of the electronic cigarette by means of a touch screen:
the display interface on the electronic display screen is provided with a plurality of functional icons. Firstly, the user selects the mode switching function, and the controller 5 controls the electronic display screen to enter the interface of the mode switching function after receiving the electric signal for entering the mode switching function. After the electronic display screen enters the interface with the mode switching function, the interface for mode selection is displayed on the electronic display screen, and icons corresponding to the three working modes are arranged in the interface for mode selection. The user then determines one of the modes of operation (i.e., the third mode of operation). The controller 5 sends a power adjustment signal corresponding to the third operating mode to the power adjustment circuit 7. After the power adjusting circuit 7 receives the power adjusting signal, parameters of circuit elements are adjusted to make the output power of the battery device be a power value corresponding to the third working mode, and then the electronic cigarette enters the third working mode to work.
When the voltages in the two battery slots 1 are greater than the preset voltage threshold, the user can also switch between the low power mode and the power saving mode as required, and the switching process is similar to the above. Except that the high power mode in the mode selection interface is in the non-selectable state, for example, the controller 5 controls the state of the high power mode on the display screen to be in the gray non-selectable state; for another example, the controller 5 controls the state of the high power mode on the display screen to be a hidden state; and so on.
When the voltage in one battery jar 1 is greater than the preset voltage threshold, the controller 5 controls both the high-power mode and the low-power mode to be in the non-selectable state, and the user can only select the power-saving mode.
In addition, when the current voltage of the batteries in at least two battery slots 1 in the battery device is larger than the preset voltage threshold, the user can also select any one or more batteries in the battery slots 1 to supply power. For example, when the current voltages of the batteries in the two battery slots 1 are both greater than the preset voltage threshold, the user may select any one of the two battery slots 1 to supply power, in addition to selecting all the batteries in the two battery slots 1 to supply power at the same time; when the current voltage of the batteries in the three battery tanks 1 is greater than the preset voltage threshold, the user may select any one or two of the three battery tanks 1 to supply power, in addition to selecting all the batteries in the three battery tanks 1 to supply power at the same time.
Optionally, when the battery in one or more battery slots 1 in the battery device consumes too much power, the controller may adjust the operation mode appropriately, and the corresponding processing procedure may be as shown in fig. 5, and includes the following steps:
in step 501, when it is determined that the power consumption speed of the battery in one or more battery slots 1 is greater than the preset power consumption speed threshold according to the voltage of the battery loaded in each battery slot 1, the controller 5 determines the total voltage of all the current battery slots 1.
Wherein, the power consumption speed is the reduction of the battery capacity in unit time.
The principle of the controller 5 detecting the power consumption speed may be:
first, the controller 5 periodically detects the voltage in the battery container 1 according to the principle of detecting the voltage described in the first embodiment. Then, the controller 5 converts the voltage into the electric quantity based on the relationship between the voltage and the electric quantity stored in advance. And finally, determining the power consumption speed of the battery jar 1 according to the power consumption reduction amount in one period.
In implementation, when the controller 5 detects that the power consumption speed of one battery jar 1 or some battery jars 1 is greater than the preset power consumption threshold, the controller 5 detects the total voltage of all the current battery jars 1.
Wherein, according to the fact that the larger the total voltage is, the higher the output power of the corresponding working mode is, the correspondence between the working mode and the total voltage stored in advance in the controller 5 may be: as shown in table 3, when the total voltage is in the range greater than or equal to a, the high power mode is corresponded; when the total voltage is in a range greater than b and less than a, corresponding to a low-power mode; when the total voltage is in the range of less than or equal to b, which is greater than b, for example, a may be 10 volts and b may be 5 volts, the power saving mode corresponds.
TABLE 3
| Total voltage value | Mode of operation |
| [a，﹢∞) | High power mode |
| (b，a) | Low power mode |
| (﹣∞，b] | Power saving mode |
In implementation, the controller 5 determines the total voltage of all the battery slots 1 at present. Further, the operation mode (i.e., the second operation mode) corresponding to the voltage value may be looked up in the correspondence table.
In step 503, the controller 5 sets the operation mode to the second operation mode.
In this step, the controller 5 also adjusts the output power of the circuit by using the circuit adjusting circuit 7, the specific adjusting process is similar to that in step 402, and details are shown in step 402 and are not described herein again.
In this way, when the power consumption speed of the battery in one or more battery slots 1 is greater than the preset power consumption speed threshold, the controller 5 determines the corresponding working mode according to the corresponding relationship between the total voltage of all the current battery slots 1 and the working mode. Therefore, the electronic cigarette can be prevented from working in a working mode with higher output power when the power consumption speed of one or more batteries in the electronic cigarette is greater than a preset power consumption speed threshold value, so that the service time of the electronic cigarette is shortened.
Optionally, when the power consumption speed of the battery in one or more battery slots 1 is greater than a preset power consumption speed threshold, the electronic cigarette may perform a corresponding prompt to the user, and the corresponding processing may be: when the power consumption speed of the batteries in one or more battery slots 1 is determined to be larger than a preset power consumption speed threshold value according to the voltage of the batteries loaded in each battery slot 1, the controller 5 controls a first prompting component of the battery device to send out a first prompting signal.
Wherein the first prompting means is a means capable of signaling attention of the user.
In implementation, when the controller 5 detects that the power consumption speed of the battery in one of the battery slots 1 is greater than the preset power consumption threshold, the controller 5 sends an electric signal corresponding to the first prompt signal to a first prompt component in the battery device, and the first prompt component sends the first prompt signal after receiving the electric signal. For example, the first prompt component may be a warning light, the first prompt signal is a flashing of the warning light, when the controller 5 detects that the power consumption speed of the battery in one of the battery slots 1 is greater than a preset power consumption threshold, the controller 5 sends an electrical signal corresponding to the flashing of the warning light, and the warning light flashes after receiving the electrical signal. For another example, the first prompting member may be a vibrator, the first prompting signal may be vibration, and the control process of the controller 5 may be similar to that described above. For another example, the first prompting component may be a buzzer, the first prompting signal may be a sound, and the control process of the controller 5 is similar to the above.
The control method for controlling the first prompt component of the battery device to send the first prompt signal by the controller 5 can remind a user to change the working mode of the electronic cigarette in time, and prevent the electronic cigarette from working in a high-power mode to cause too fast power consumption of the electronic cigarette. Thus, the service life of the electronic cigarette can be prolonged.
Optionally, when the voltage in all the battery slots 1 in the battery device is lower than the preset voltage threshold, the electronic cigarette may also prompt the user accordingly. The corresponding processing may be: when the voltages of all the battery slots 1 are lower than the preset voltage threshold, the controller 5 controls a second prompting component of the battery device to send out a second prompting signal.
Wherein the second prompting means is also a means capable of signaling attention of the user. The controller 5 controls the second prompting component to send out the second prompting signal, which is described in detail in the above description that the controller 5 controls the first prompting component to send out the first prompting signal, and is not described here again.
The control method for controlling the second prompt part of the battery device to send the second prompt signal by the controller 5 can remind a user to charge the battery of the electronic cigarette in time or replace the battery in time so as to avoid delaying use.
Optionally, the controller 5 may further control the electronic display screen to display the remaining power of the battery in each battery jar 1, and the corresponding processing may be as shown in fig. 6, including the following steps:
in step 601, the controller 5 determines the remaining capacity of the battery in each battery container 1 according to the current voltage of each battery container 1.
In implementation, the controller 5 first detects the voltage of the battery in each battery container 1 according to the principle of detecting the voltage of the battery in the battery container 1 described in the first embodiment. Then, the voltage of each battery well 1 is converted into the current charge amount (i.e., the remaining charge amount) of each battery based on the relationship between the voltage and the charge amount stored in advance.
In step 602, the controller 5 controls the display part of the battery device to display the remaining capacity of the battery in each battery container 1.
Wherein, the display component can be an electronic display screen of the electronic cigarette.
In operation, after the controller 5 determines the remaining capacity of the battery in each battery well 1, it sends an electrical signal corresponding to the remaining capacity of the battery in each battery well 1 to the electronic display. After the electronic display screen receives the electric signals, the residual capacity of the battery in each battery jar 1 is displayed on the electronic display screen. Wherein, the mark displayed on the electronic display screen by each battery jar 1 is the same as the mark of each battery jar 1. For example, the mark of the battery container 1 at the container mounting position is set to M, and the M mark of the battery container 1 and the remaining capacity of the battery in the battery container 1 can be displayed on the electronic display screen. Therefore, the user can find out which battery jar 1 has insufficient residual capacity in time and replace the battery in the corresponding battery jar 1 in time.
In the embodiment of the disclosure, when the power supply control method is used to control the battery device to supply the operating voltage to the atomizer, when the battery capacity in any battery jar of the battery device is very low (that is, the voltage is not greater than the preset voltage threshold), or the contact between any battery jar and the battery is poor, or there is no battery in any battery jar, the controller sends a closed electrical signal to an electrically controlled battery switch connected in parallel with the battery jar, and the electrically controlled battery switch is closed after receiving the electrical signal, so as to short-circuit the battery jar. The short-circuiting of the battery container does not stop the batteries in the other battery containers from supplying the operating voltage to the atomizer. Therefore, as long as a battery groove is arranged in the battery device and a battery which can work is arranged in the battery groove, the battery device can work normally, and therefore the electronic cigarette can also work normally.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
