DETAILED DESCRIPTION OF THE EMBODIMENTS
Referring to FIG. 1 in conjunction with FIG. 2, an electronic cigarette with wireless communication function is provided according to the disclosure, including an electronic cigarette body.
The electronic cigarette body is disposed with an atomizer assembly 11 configured to atomize nicotine liquid and a battery assembly 12 configured to power elements inside the electronic cigarette body. The electronic cigarette further includes a communication assembly 13, which is disposed between the atomizer assembly 11 and the battery assembly 12, and configured to communicate with an external terminal.
The communication assembly 13 is further provided with a first connecting end 121 detachably connected to the battery assembly 12, a second connecting end 111 detachably connected to the atomizer assembly 11, and a conductive module 26 configured to connect the battery assembly 12 to the atomizer assembly 11, so that the battery assembly 12 may power the conductive module 26.
The communication assembly 13 is further provided with a microcontroller 24, which is electrically connected to the conductive module 26, and configured to record smoking information of the electronic cigarette according to electrical signals from the conductive module 26 and control operation of modules inside the communication assembly 13, and a wireless communication module 21, which is connected electrically to the microcontroller 24, and configured to establish communication connection to the external terminal and perform data transmission.
In view of this, it is can be seen that the microcontroller 24 is electrically connected to the conductive module 26, so that when a user puffs on the electronic cigarette, the microcontroller 24 acquires operation state of the electronic cigarette by detecting the level of the conductive module 26.
The communication assembly 13 acquires the smoking information of the user through the microcontroller 24, the wireless communication module 21 transmits the smoking information to the terminal, and thus the user gets to know his/her smoking information through the terminal. The smoking information herein may include smoking duration, puff number and smoking times, etc. In this case, the user may grasp his/her smoking information, and may adjust smoking habits according to his/her status, so that the user may keep a good physical state. Meanwhile, the user is also more interested in puffing on the electronic cigarette, during which the user has an experience differing from puffing on a normal cigarette. The communication assembly 13 is detachable connected to the battery assembly 12 and the atomizer assembly 11 respectively. The detachable structure design is beneficial for assembly and disassembly for the communication assembly. If the user needs communication, the communication assembly may be assembled between the battery assembly and the atomizer assembly, and the communication assembly may be disassembled when not needed, thereby not affecting normal use of the electronic cigarette. It is can be said the structure is simple and ingenious, and has high reliability and good portability.
According to an embodiment of the disclosure, referring to FIG. 1, the battery assembly 12 is provided with a third connecting end 43 detachably connected to the first connecting end 121, and the atomizer assembly 11 is provided with a fourth connecting end 42 detachably connected to the second connecting end 111, where the third connecting end 43 is capable of being detachably connected to the fourth connecting end 42 to form the electronic cigarette body.
In view of this, it is may be seen that the battery assembly 12 is detachably connected to the atomizer assembly 11 through the third connecting end 43 and the fourth connecting end 42 to form the electronic cigarette. In this case, smoking function of the electronic cigarette may be achieved without assembling the communication assembly 13. In the connection structure, the communication assembly 13 may be disassembled, and the battery assembly 12 and the atomizer assembly 11 form the electronic cigarette, therefore the electronic cigarette will not transmit smoking information of the user to the outside world, leakage for data of personal smoking status and physical state is better avoided and personal privacy is well protected.
In a case that the user wants to discard an electronic cigarette, the user may disassemble the communication assembly 13 and assemble the communication assembly 13 to another electronic cigarette with the same connection way. In this case, the smoking information of the user is prevented to be leaked when the user discards the electronic cigarette equipped with the communication assembly 13. Ordinarily, when the user wants to use an electronic cigarette with communication function, the user may connect the communication assembly 13 to an electronic cigarette with the same connection way. Therefore it does not require each electronic cigarette is provided with the communication assembly 13. Thus the cost for buying the electronic cigarette is saved, and the electronic cigarette is easy to be replaced and is portable. The detachable connection structure of the communication assembly 13 is beneficial for the user to select a period of time to record smoking status of the user, the user may arbitrarily select to record or not, thereby improving user experience.
The communication assembly 13 is detachably disposed between the battery assembly 12 and the atomizer assembly 11, avoiding that electro magnetic wave generated by signal transmission of the communication assembly 13 interferes with an airflow sensor 37 inside the battery assembly 12 which may cause false triggering of the electronic cigarette, when the communication assembly 13 is disposed in the end region of the battery assembly 12 for a long time. It can further avoid that tobacco tar leaked from the atomizer assembly 11 causes short circuit of the communication assembly 13 when the communication assembly 13 is disposed at an end of the battery assembly 12, which is connected to the atomizer assembly 11, for a long time.
According to an embodiment of the disclosure, a airflow channel is provided inside the atomizer assembly 11, the battery assembly 12 and the communication assembly 13. The airflow channel passing through the atomizer assembly 11, the battery assembly 12 and the communication assembly 13 is configured for air circulation when smoking, and the atomizer assembly 11, the communication assembly 13 and the battery assembly 12 are coaxially disposed, thereby ensuring that the airflow channel is unimpeded. An airflow sensor 37 and a control module 38 are disposed in the airflow channel inside the battery assembly 12.
The airflow sensor 37 is configured to sense pressure change in the airflow channel, and transmit smoking signal to the control module 38 according to the pressure change in the airflow channel in the battery assembly 12. The control module 38 is configured to control the battery assembly 12 to power the atomizer assembly 11 according to the smoking signal transmitted by the airflow sensor 37. A push-button control switch may also be disposed on the battery assembly 12, and the battery assembly 12 is controlled by the push-button control switch to power the atomizer assembly 11, which is not limited herein.
To make the purpose, features and merits of the disclosure more obvious and understandable, the technical solutions are clearly and completely described in the following in conjunction with drawings according to the embodiments of the disclosure. Apparently, the described embodiments are merely a few rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons of ordinary skill in the art are based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

The timing unit is configured to record smoking duration, and store the smoking duration into the storage unit. The counting unit is configured to record the number of times of a user smoking, and store the number into the storage unit.
Specifically, when the microcontroller 24 detects that the user is smoking, the timing unit starts to record smoking duration of the user, and the counting unit starts to record the number of puffs of the user or record the number of times of the user smoking during one day and transmit the recorded data to the storage unit.
According to the embodiment, the communication assembly 13 is provided with a power battery 31, and the power battery 31 is configured to power elements of the communication assembly 13.
When the battery assembly 12, the atomizer assembly 11 and the communication assembly 13 are connected, the battery assembly 12 is connected to the atomizer assembly 11 through the conductive module 26, and thus the battery assembly 12 may power the atomizer assembly 11. When the user puffs on the electronic cigarette, the battery assembly 12 supplies electric power to the atomizer assembly 11. At this time the microcontroller 24 detects that the conductive module 26 is at high level, and the timing unit of the microcontroller 24 starts timing, and records the smoking duration of the user. The counting unit starts recording the number of puffs of the user. Specific recorded content is not limited herein. When the user stops smoking, the microcontroller 24 transmits the smoking information of the user to the storage unit, and controls the wireless communication module 21 to transmit the smoking information to a connected terminal through the wireless communication module 21. Alternatively, the microcontroller 24 may also control the wireless communication module 21 to transmit the smoking information to the terminal through the wireless communication module 21 when a preset number of times of the user smoking or a preset time period for using the electronic cigarette, such as one day, one week or one month, is reached. The way of transmitting information and transmitting time are not limited herein.
According to the embodiment, network connection needs to be established before the wireless communication module 21 transmits data to the terminal. The wireless communication module 21 may be connected through WIFI or Bluetooth, etc. Specially, according to the embodiment, the wireless communication module 21 may search a network hotspot in a certain range, establish wireless network connection, and transmit information to a terminal device through the network hotspot.

Specific used connection ways are not limited herein.
According to the embodiment, due to presence of the individual power battery 31, the power battery 31 may power the wireless communication module 21, thereby ensuring that the electronic cigarette is connected to the terminal. The microcontroller 24 may also perform the following control. When the user stops smoking, the microcontroller 24 senses that the conductive module 26 is at low level, so that the microcontroller 24 controls the power battery 31 to stop powering the wireless communication module 21, thereby may save electric energy of the power battery 31.
According to the embodiment, the communication assembly 13 is detachably connected to the battery assembly 12 and the atomizer assembly 11 respectively. Specially, the detachable connection may be threaded connection, snap-fit connection or magnet adhesion. According to the embodiment, the detachable connection is threaded connection.

The conductive module 26 is provided with a first conductive end 81 and a second conductive end 82 which are disposed at the first connecting end 121 and the second connecting end 111. The first conductive end 81 is electrically connected to the positive electrode connecting end 61 and the outer electrode 71 respectively, the second conductive end 82 is electrically connected to the negative electrode connecting end 62 and the inner electrode 72 respectively, so that the positive electrode connecting end 61 is electrically connected to the outer electrode 71 through the first conductive end 81, and the negative electrode connecting end 62 is electrically connected to the inner electrode 72 through the second conductive end 82, therefore the battery assembly 12 may power the atomizer assembly 11.
Specially, according to the embodiment, the communication assembly 13 is detachably connected to the battery assembly 12 and the atomizer assembly 11 respectively, where the detachable connection is threaded connection. The first connecting end 121 and the second connecting end 111 have threads adaptively connected to the battery assembly 12 and the atomizer assembly 11 respectively. The first conductive end 81 of the conductive module 26 may be integrated with the first connecting end 121 as a whole, i.e., the first connecting end 121 is made of conductive material. Alternatively conductive material of the first conductive end 81 may be individually disposed on the first connecting end 121. The second conductive end 82 of the conductive module 26 may be integrated with the second connecting end 111 as a whole, i.e., the second connecting end 111 is made of conductive material. Alternatively conductive material of the second conductive end 82 may be individually disposed on the second connecting end 111. According to the embodiment, the first conductive end 81 and the first connecting end 121 are integrated as a whole, and the second conductive end 82 and the second connecting end 111 are integrated as a whole, so that a closed loop is formed by connecting the atomizer assembly 11 to the second connecting end 111, and connecting the battery assembly 12 to the first connecting end 121, therefore the battery assembly 12 may power the atomizer assembly 11.
According to the embodiment, the communication assembly 13 is further provided with a switch module 32, configured to control to turn on or turn off the communication assembly 13, and control the communication assembly 13 to transmit information. For example, pressing the switch module 32 one time may turn on or turn off the communication assembly 13.

In this case, the user may control the communication assembly 13 through the switch module 32. The switch module 32 may be a button switch.
According to the embodiment, the electronic cigarette body is further provided with an oil storage assembly 14 connected to the atomizer assembly 11, where the oil storage assembly 14 is configured to store nicotine liquid.

A CC2543 chip, i.e., a 2.4 GHz radio wireless system-on-chip with a 32 Kb flash memory and 16 bus extenders may be used. The CC2543 chip supports iBeacon technology, i.e., a signal region may be automatically created by using bluetooth technology iBeacon with low power consumption. When a device enters into the region, a corresponding application may prompt the user whether to access the signal network. Through a small wireless sensor which may be disposed into any object and bluetooth technology with low power consumption, the user may use a smart device to transmit data.

The terminal may receive the ID. Meanwhile, the wireless communication module 21 supports wireless communication function, i.e., the electronic cigarette may perform wireless communication with product of the same type nearby.
Second embodiment will be described below with reference to FIG. 4.
The electronic cigarette according to the second embodiment also has technical features of that according to the first embodiment, but the electronic cigarette according to the second embodiment has following difference to that according to the first embodiment.
When a user puffs on an electronic cigarette, the battery assembly 12 powers the atomizer assembly 11 through the conductive module 26 to atomize tobacco tar, while the battery assembly 12 powers elements of the communication assembly 13 through the conductive module 26.
The communication assembly 13 is further provided with an energy-storage capacitor module electrically connected to the conductive module 26. When the user puffs on the electronic cigarette, the battery assembly 12 powers the atomizer assembly 11 through the conductive module 26 to atomize tobacco tar, and meanwhile the battery assembly 12 charges the energy-storage capacitor through the conductive module 26. When the battery assembly 12 stops powering the communication assembly 13, the energy-storage capacitor module powers the elements of the communication assembly 13.
Specially, when the user puffs on the electronic cigarette, the battery assembly 12 powers the atomizer assembly 11. Since the first conductive end 81 and the first connecting end 121 are integrated as a whole and the second conductive end 82 and the second connecting end 111 are integrated as a whole, a closed loop is formed by connecting the atomizer assembly 11 to the second connecting end 111 and connecting battery assembly 12 to the first connecting end 121. Thus the battery assembly 12 may power the atomizer assembly 11. Meanwhile, according to the embodiment, the communication assembly 13 is also powered by the battery assembly 12, and charges the energy-storage capacitor module.
Once the communication assembly 13 is electrified, the counting unit of the microcontroller for the communication assembly 13 counts one time with the count being stored in the storage unit, and timing is started. The communication assembly 13 transmits some smoking data stored in the storage unit through the wireless communication module 21 to a terminal such as a cellphone, etc. The terminal analyzes and displays the data to the user. When the user stops smoking, i.e., when the battery assembly 12 stops powering the atomizer assembly 11, the communication assembly 13 according to the embodiment also powers off. When the microcontroller 24 of the communication assembly 13 detects that the conductive module 26 is at low level, i.e., when the communication assembly 13 powers off, the communication assembly 13 stops timing, and stores the timing result. At the moment, the communication assembly 13 is temporarily powered by the energy-storage capacitor module electrically connected to the conductive module 26. When the user smokes next time, the communication assembly 13 reads the stored data again, and transmits the data to the terminal.
According to the embodiment, the energy-storage capacitor module includes capacitors C7, C11, C12, C13, C14 and C15 in the circuit.

When the user puffs on the electronic cigarette, the battery assembly 12 powers the atomizer assembly 11 through the conductive module 26 to atomize tobacco tar, and the battery assembly 12 also powers the rechargeable battery 41 through the conductive module 26. The rechargeable battery 41 is configured to power elements of the communication assembly 13 when the battery assembly 12 stops powering the elements of the communication assembly 13.
Specially, when the user puffs on the electronic cigarette, the battery assembly 12 is electrically connected to the conductive module 26 to power the elements of the communication assembly 13 and charge the rechargeable battery 41. When the user stop smoking, the battery assembly 12 is disconnected to the conductive module 26, and the rechargeable battery 41 powers the elements of the communication assembly 13.
According to the embodiment, cost of communication modules 13 is saved more relative to that of the first embodiment, and a small back-up battery may be used as the rechargeable battery 41, therefore volume of the communication assembly 13 is small. Operation of the communication assembly 13 is more stabilize relative to that according to the second embodiment, and the communication assembly 13 may operate when smoking is not performed.
According to the embodiment, the communication assembly 13 is further provided with a diode protection module 51 including a resistor 512 and a first diode 511. The resistor 512 is connected to the first diode 511 in parallel. The diode protection module 51 is connected to the positive electrode of the rechargeable battery 41. The first diode 511 is turned on to prevent reverse current from burning the rechargeable battery 41, when the rechargeable battery 41 powers the communication assembly 13. And when the battery assembly 12 powers the communication assembly 13, the rechargeable battery 41 is charged through the resistance 512.
According to the embodiment, the conductive module 26 is provided with a second diode 52. The second diode 52 is turned on to prevent reverse current from burning the battery assembly 12, when the battery assembly 12 powers the communication assembly 13.
The fourth embodiment will be described below with reference to FIG. 6.
The communication module 13 according to the embodiment is powered by using any one of power supply modes according to the foregoing embodiments. The difference is that the wireless communication module 21 according to the embodiment includes a common bluetooth chip to realize wireless communication function.
