Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Because in the prior art, the disposable electronic cigarette has the advantages of no liquid leakage, convenient carrying and the like, but due to the closed design of the electronic cigarette, a user cannot replace the cigarette bullet of the electronic cigarette, so that the taste of the disposable electronic cigarette is single.

The utility model provides a solution, at least two atomizers configured as different tastes are arranged in a circuit structure of the electronic cigarette, and the switching is realized through the MOS switch, so that the tastes of the disposable electronic cigarettes are diversified.

The following description will explain the circuit structure of the electronic cigarette applied in the implementation of the technology of the utility model:

the utility model provides a first embodiment of a circuit structure of an electronic cigarette, in the embodiment, the circuit structure comprises a power supply 10, a micro-control unit 20, at least two MOS switches 30 and at least two atomizers 40, wherein each MOS switch 30 is connected with the power supply 10, and the at least two MOS switches 30 and the at least two atomizers 40 are consistent in number and are connected in series in a one-to-one correspondence manner; the tastes of the MOS tubes are different;

In this embodiment, the control information may be on control information for controlling the MOS switch 30 to be turned on, or off control information for controlling the MOS switch 30 to be turned off. The micro-control unit 20 may be used for controlling and processing at least part or all of the functions in the electronic cigarette, such as detecting whether the atomizer device is in normal contact, or sending control information to the MOS switch 30 to control the on or off of the MOS switch.

The MOS switch 30 may be a switching component that turns on or off a circuit based on control of control information. The atomizer 40 may be a cartomizer structure in an electronic cigarette.

For example, the micro-control unit 20 is connected to the battery 10 and the control terminal of the MOS switch 30 in series, and the source (S) and the drain (D) of the MOS switch 30 are connected to the power supply 10 and the atomizer 40 in series, respectively. After the micro-control unit 20 sends the conduction control information to the MOS switch 30, the MOS switch 30 is turned on under the control of the conduction control information, and the atomizer 40 is started based on the power supply of the power supply 10, so that the tobacco tar in the atomizer is heated to bring the tobacco tar into play, and a smoke effect is formed when a user sucks the electronic cigarette.

It can be understood that after the micro-control unit 20 sends the turn-off control information to the MOS switch 30, the MOS switch 30 is turned off under the control of the turn-off control information, and the power supply 10 cannot supply power to the atomizer 40, so that the atomizer stops running.

In this embodiment, the circuit structure includes a power supply 10, a micro control unit 20, at least two MOS switches 30 and at least two atomizers 40, where each MOS switch 30 is connected to the power supply 10, and the at least two MOS switches 30 and the at least two atomizers 40 are identical in number and are connected in series in a one-to-one correspondence manner; the taste of each of the atomizers 40 is different; the control end of each MOS switch 30 is connected to the micro-control unit 20 to receive control information of the micro-control unit 20, where the MOS switch 30 is turned on or off under the control of the control information to control the corresponding atomizer 40 to start or stop running. Therefore, in the utility model, at least two atomizers configured as different tastes are arranged in the circuit structure of the electronic cigarette, and the switching is realized through the MOS switch, so that the tastes of the disposable electronic cigarettes are diversified.

In addition, in this embodiment, the at least two atomizers 40 can increase the oil storage capacity of the disposable electronic cigarette by at least one time, so as to solve the problem of small oil storage capacity of the disposable electronic cigarette and increase the service time of the disposable electronic cigarette.

Referring to fig. 1, fig. 1 shows a schematic circuit diagram of a second embodiment of a circuit structure of an electronic cigarette according to the present utility model.

In this embodiment, the at least two MOS switches 30 include a first MOS switch 301 and a second MOS switch 302, and the at least two atomizers 40 include a first atomizer 401 and a second atomizer 402;

the power supply 10 is connected to the first atomizer 401 through the first MOS switch 301, and a control end of the first MOS switch 301 is connected to the micro control unit 20 to receive first control information of the micro control unit 20, where the first MOS switch 301 is turned on or off under control of the first control information to control the first atomizer 401 to start or stop running;

the power supply 10 is connected to the second atomizer 402 through the second MOS switch 302, and a control end of the second MOS switch 302 is connected to the micro control unit 20 to receive second control information of the micro control unit 20, where the second MOS switch 302 is turned on or off under control of the second control information to control the second atomizer 402 to start or stop running.

Referring to fig. 2, in order to facilitate the user to quickly switch the taste of the electronic cigarette, the circuit structure further includes a first manual operation module 50 and a second manual operation module 60, wherein the first manual operation module 50 is connected with the micro-control unit 20, and the second manual operation module 60 is connected with the micro-control unit 20; the micro control unit 20 is further configured to generate the first control information after detecting a first preset operation of the user on the first manual operation module 50; or after detecting a second preset operation of the user on the second manual operation module 60, second control information is generated.

In the present utility model, the first preset operation may be that the user presses the first manual operation module once. The second preset operation may be a user pressing the second manual operation module once. The first manual operation module may be a first key, and the second manual operation module may be a second key.

It can be understood that the electronic cigarette in the prior art is further provided with a cigarette cartridge, generally the cigarette cartridge is a suction nozzle part, and an electronic cigarette manufacturing factory can bond the atomizer and the cigarette cartridge together according to the requirements of customers to form a disposable atomizer, so that the color of the suction nozzle can be changed, and the problem that the smoke liquid flows back into the suction nozzle or flows into a battery part to corrode a circuit due to too much or too little liquid injection by a factory professional is avoided. That is, the atomizer 40 includes an atomizing wire and an oil reservoir, and the atomizing wire is used for heating the tobacco tar in the oil reservoir when the atomizer 40 is started.

Specifically, when the micro control unit 20 detects that the user presses the first manual operation module, the micro control unit 20 may generate first conduction control information and send the first conduction control information to the first MOS switch 301, the first MOS switch performs conduction action based on control of the first control information, the first atomizer 401 is started, and the power supply 10 supplies power for heating of the atomizing wire in the first atomizer 401, so that tobacco tar in the atomizer 401 in the electronic cigarette is exerted, so as to form a smoke effect. When the user presses the second manual operation module, the micro control unit 20 generates and sends first turn-off control information to the first MOS switch 301 to control the first MOS switch 301 to turn off, and generates second turn-on control information to the second MOS switch 302 to control the second MOS switch 302 to turn on, at this time, the second atomizer 402 is started, and the power supply 10 supplies power for heating the atomizing wire in the second atomizer 402, so that the tobacco tar in the second atomizer 402 in the electronic cigarette is exerted.

Correspondingly, when the user presses the first manual operation module 50 again, the micro control unit 20 may generate and send the second turn-off control information to the second MOS switch 302 to control the second MOS switch 302 to turn off, thereby controlling the second atomizer to stop operating. And simultaneously generates and sends a first conduction signal to the first MOS switch 301 to control the first MOS switch 301 to be turned on, thereby controlling the first atomizer to be started. Accordingly, when the user presses the second manual operation module 60, the micro control unit 20 performs the opposite steps described above, which will not be described again.

In this embodiment, the micro control unit 20 generates and sends the first control information or the second control information to the first MOS switch 301 connected to the first atomizer 401 or the second MOS switch 302 connected to the second atomizer 402 based on the detected first preset operation of the first manual operation module 50 or the second preset operation of the second manual operation module 60 by the user, so as to control the on or off of the first MOS switch 301 or the second MOS switch 302, thereby controlling the start or stop of the first atomizer 401 or the second atomizer 402, and further realizing the rapid switching of different tastes of the electronic cigarette in response to the user operation, so as to increase the smoking interest and experience feeling of the user.

In an embodiment, in order to avoid the situation that the usage time of the disposable electronic cigarette is short due to the fact that the heating power of the atomizer 40 is too high, the tobacco tar is too fast to exert, the circuit structure of the disposable electronic cigarette further comprises at least two power adjustment modules 80, and the at least two power adjustment modules 80 and the at least two atomizers 40 are consistent in number and are connected in series in a one-to-one correspondence manner; each power adjustment module 80 is connected to the micro control unit 20, so as to receive the power control information output by the micro control unit 20, and control the heating power of the corresponding atomizer 40 according to the power control information.

It is understood that, in the circuit structure of the electronic cigarette, the power adjustment module 80 may be connected to the MOS switch 30 to form the power control module 90 to adjust the heating power of the electronic cigarette. Taking an example that the electronic cigarette has two atomizers, the first power adjustment module 801 is connected with the first MOS switch 301 to form a first power control module 901, and the second power adjustment module 802 is connected with the second MOS switch 301 to form a second power control module, and the specific structure is shown in fig. 3.

Specifically, when the MOS switch 30 is turned on under the control of the on control information, the micro control unit 20 generates and transmits the power control information to the power adjustment module 80, and the power adjustment module 80 adjusts the heating power of the corresponding atomizer 40 according to the power control information. The heating power of the atomizer 40 is determined by the output voltage and the resistance of the atomized filaments. It can be understood that when the resistance value of the atomized filament is fixed, the micro control unit 20 outputs PWM (Pulse width modulation ) waveforms with different duty ratios to the power adjustment module 80, and the atomizer 40 receives and forms the duration of the PWM adjustment output voltage with the corresponding duty ratio, thereby achieving the purpose of adjusting the power.

In this embodiment, through setting up power adjustment module in the circuit structure of electron cigarette, can control atomizer heating's power to avoid appearing because of atomizer heating power is too big, and the too fast condition of leading to the tobacco tar to volatilize appears, and then increased disposable electron cigarette's live time.

In order to enable a user to know the residual oil quantity of the disposable electronic cigarette at any time in the process of sucking the disposable electronic cigarette, the utility model also adds an oil quantity display module 70 in the circuit structure so as to represent the residual oil quantity of the disposable electronic cigarette by different colors. The fuel display module may be an electronic display screen or LED lamp, or in one example, the fuel display module may be an RGB fuel lamp that may display at least 4 colors.

Wherein the first total pumping time is less than the second total pumping time, the second total pumping time is less than the third total pumping time, and the first display color, the second display color, the third display color and the fourth display color are different forms of color. If the first display color may be green, the second display color may be orange, the third display color may be blue, and the fourth display color may be red.
