The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Please refer to FIG. 1 , which is a schematic diagram of the structure of the electronic atomization device of the present application.

The electronic atomization device includes an atomizer 100 and a power supply device 200 .

The nebulizer 100 stores a nebulizer matrix, and the nebulizer 100 can heat and atomize the nebulizer matrix to form an aerosol for the user to inhale.

Specifically, the atomizer 100 may include a first battery 150 and an atomizer assembly 130. The first battery 150 and the atomizer assembly 130 are electrically connected, the atomizer matrix is stored in the atomizer assembly 130, the atomizer assembly 130 heats the atomizer matrix and atomizes it to form an aerosol, and the aerosol flows out from the suction nozzle 160 provided on the atomizer 100.

The power supply device 200 is detachably connected to the atomizer 100 , that is, the power supply device 200 can be fixedly connected to the atomizer 100 or can be separated from each other.

The power supply device 200 includes a second battery 230 , and the second battery 230 stores electrical energy. When the controller 200 is connected to the second battery 230 , the second battery 230 in the power supply device 200 can charge the first battery 150 in the atomizer 100 .

Further, the atomizer 100 is provided with a first circuit interface group 110, and the power supply device 200 is provided with a second circuit interface group 210. When the atomizer 100 is connected to the power supply device 200, the first circuit interface group 110 is electrically connected to the second circuit interface group 210. The first circuit interface group 110 and the second circuit interface group 210 are used for signal interaction between the atomizer 100 and the power supply device 200, and can also be used for the power supply device 200 to charge the atomizer 100.

Therefore, in this embodiment, the atomizer 100 has the function of storing and atomizing the atomized matrix, and the atomizer 100 is provided with a first battery 150, which can directly power the atomizer assembly 130, and the atomizer 100 can be used independently of the power supply device 200. When the atomizer 100 is performing atomization, the atomizer 100 and the power supply device 200 can be separated at will, so that the atomizer 100 and the power supply device 200 have the function of hot plugging, which improves the safety of the use of the atomizer 100. In addition, the detachability of the atomizer 100 and the power supply device 200 improves the playability of the electronic atomization device, so that the electronic atomization device has more ways to play and improves the user experience.

When the atomizer 100 and the power supply device 200 are connected to each other, the power supply device 200 can charge the atomizer 100. At the same time, the atomizer 100 can perform atomization during charging, that is, the electronic atomization device under this embodiment can also be used for suction during the charging process of the atomizer 100, making the use of the electronic atomization device more convenient.

The power supply device 200 in this embodiment can determine whether it is stably connected to the atomizer 100 based on the detection information of the second circuit interface group 210, and then determine whether to charge the atomizer 100, thereby further improving the safety of use of the electronic atomization device of the present application. Please refer to the following embodiments for details.

Furthermore, the atomizer 100 includes a first circuit board 120 , the atomizer assembly 130 and the first battery 150 are electrically connected to the first circuit board 120 , respectively, and the first circuit interface group 110 is disposed on the first circuit board 120 .

Optionally, a control chip or a control circuit may be integrated on the first circuit board 120 , and the control chip or the control circuit may control the charging and discharging of the first battery 150 , so that the first battery 150 is charged or the atomization operation of the atomization assembly 130 is controlled.

The power supply device 200 further includes a second circuit board 220 , and a second battery 230 is electrically connected to the second circuit board 220 .

Optionally, a control chip or a control circuit may be integrated on the second circuit board 220. For example, in this embodiment, the second circuit board 220 includes a control chip 240.

The control chip 240 can control the charging and discharging of the second battery 230 to charge the second battery 230 , or control the second battery 230 to charge the first battery 150 through the first circuit interface group 110 and the second circuit interface group 210 .

Optionally, a charging interface 221 may be provided on the second circuit board 220. The charging interface 221 is used to connect other power sources to charge the second battery 230. In addition, the second circuit board 220 may also be provided with circuit elements such as a current conversion circuit and an indicator light.

In this embodiment, the control chip 240 can obtain the detection information of the second circuit interface group 210, and then determine whether to charge the atomizer 100 based on the detection information. If the control chip 240 determines that the atomizer 100 needs to be charged, the control chip 240 controls the second battery 230 to charge the first battery 150.

Furthermore, the first circuit interface group 110 includes a first signal interface 112 , a first power interface 111 and a second power interface 113 , and the second circuit interface group 210 includes a second signal interface 212 , a third power interface 211 and a fourth power interface 213 .

The first signal interface 112 is connected to the second signal interface 212, and the first signal interface 112 and the second signal interface 212 are used to transmit signals. The first power interface 111 is connected to the third power interface 211, and the second power interface 113 is connected to the fourth power interface 213. The first power interface 111, the second power interface 113, the third power interface 211 and the fourth power interface 213 are used to transmit electric energy and can be used to charge the first battery 150. Among them, one of the first power interface 111 and the second power interface 113 is a positive interface, and the other is a negative interface, and the same applies to the third power interface 211 and the fourth power interface 213.

In this embodiment, the control chip 240 can obtain the detection information of the second signal interface 212, and then determine whether to charge the atomizer 100 based on the detection information. If the control chip 240 determines that the atomizer 100 needs to be charged, the control chip 240 controls the second battery 230 to charge the first battery 150, and the second battery 230 transmits power to the first power interface 111, the second power interface 113 and the first battery 150 through the third power interface 211 and the fourth power interface 213.

Furthermore, the atomizer 100 further includes an airflow sensor 140, which is electrically connected to the first circuit board 120. The airflow sensor 140 may be disposed in the airflow channel of the atomizer assembly 130, and is used to detect the suction action. Under the suction action of the user on the atomizer assembly 130, the airflow sensor 140 generates a response signal in response to the user's suction action on the atomizer assembly 130, and the airflow sensor 140 sends the suction signal to the control circuit of the first circuit board, and the control circuit controls the first battery 150 to energize the atomizer assembly 130, so that the atomizer assembly 130 is atomized to generate aerosol.

At the same time, the airflow sensor 140 sends the suction signal to the second signal interface 212 through the first signal interface 112. In this embodiment, the detection information of the second signal interface 212 at least includes the suction signal received by the second signal interface 212 from the first signal interface 112.

When the control chip 240 does not detect the suction signal received by the second signal interface 212, the control chip 240 controls the third power interface 211 and the fourth power interface 213 to be disconnected from the first power interface 111 and the second power interface 113, and the power supply device 200 is in a power-off state with the atomizer 100. When the control chip 240 detects the suction signal received by the second signal interface 212, the control chip 240 controls the third power interface 211 and the fourth power interface 213 to be connected to the first power interface 111 and the second power interface 113, and the control chip 240 controls the second battery 230 to supply power to the first battery 150, and the power supply device 200 starts to charge the atomizer 100.

Therefore, the control chip 240 in this embodiment determines whether the power supply device 200 is charging the atomizer 100 based on whether the second signal interface 212 receives the suction signal sent by the airflow sensor 140 in the atomizer 100, thereby preventing the power supply device 200 and the atomizer 100 from being powered on for a long time, thereby improving the connection security between the power supply device 200 and the atomizer 100.

In another embodiment, the detection information of the second signal interface 212 at least includes the number of suction signals received by the second signal interface 212 from the first signal interface 112 .

The control chip 240 detects the number of times the second signal interface 212 receives the puff signal. If the number of times the second signal interface 212 receives the puff signal is not greater than the preset number, the control chip 240 controls the third power interface 211 and the fourth power interface 213 to be disconnected from the first power interface 111 and the second power interface 113, and the power supply device 200 is in a power-off state with the atomizer 100. If the number of times the second signal interface 212 receives the puff signal is greater than the preset number, the control chip 240 controls the third power interface 211 and the fourth power interface 213 to be connected to the first power interface 111 and the second power interface 113, and the control chip 240 controls the second battery 230 to supply power to the first battery 150, and the power supply device 200 starts to charge the atomizer 100.

Optionally, the preset number of times may be 1 time, 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times or other times.

Therefore, the control chip 240 under this embodiment is based on whether the second signal interface 212 receives the suction signal sent by the airflow sensor 140 in the atomizer 100, and after the second signal interface 212 receives the suction signal, the control chip 240 records the number of times the suction signal is received, and determines whether the power supply device 200 charges the atomizer 100 based on the number of receptions, thereby preventing the power supply device 200 and the atomizer 100 from being in the power-on state for a long time, thereby improving the connection security between the power supply device 200 and the atomizer 100.

In some embodiments, the power supply device 200 further includes a resistance measuring device 250. The resistance measuring device 250 may be disposed on the second circuit board 220 and electrically connected to the second circuit board 220.

The resistance measuring device 250 is used to measure the resistance of the second signal interface 212. In this embodiment, the detection information of the second signal interface 212 at least includes the resistance of the second signal interface 212.

The control chip 240 controls the resistance measuring device 250 to continuously measure the resistance of the second signal interface 212, and obtains the resistance of the second signal interface 212. The second signal interface 212 is in a suspended state when the power supply device 200 and the atomizer 100 are separated, and the resistance of the second signal interface 212 tends to infinity. When the power supply device 200 and the atomizer 100 are stably connected, the second signal interface 212 and the first signal interface 112 are stably connected, and the resistance of the second signal interface 212 is a fixed preset resistance, which is determined by the resistance of the materials of the second signal interface 212 and the first signal interface 112, and can be set by those skilled in the art according to actual conditions.

Therefore, when the control chip 240 detects that the resistance of the second signal interface 212 is equal to the preset resistance within a certain period of time, the control chip 240 controls the third power interface 211, the fourth power interface 213 to be connected to the first power interface 111, and the second power interface 113, and the control chip 240 controls the second battery 230 to supply power to the first battery 150, and the power supply device 200 starts to charge the atomizer 100. After the control chip 240 detects that the resistance of the second signal interface 212 changes, the control chip 240 immediately disconnects the third power interface 211, the fourth power interface 213 from the first power interface 111, and the second power interface 113, and controls the second battery 230 to stop charging the first battery 150.

In this embodiment, the connection stability between the power supply device 200 and the atomizer 100 is determined by the resistance value of the second signal interface 212, and the charging circuit is opened only after the power supply device 200 and the atomizer 100 are stably connected. This prevents the third power interface 211 and the fourth power interface 213 of the power supply device 200 from being suspended and discharged, and also prevents the second signal interface 212 from being short-circuited with the third power interface 211 or the fourth power interface 213, thereby improving the safety of the electronic atomizer device and the charging stability of the atomizer 100.

In some embodiments, the power supply device 200 further includes a timing device 260 . The timing device 260 may be disposed on the second circuit board 220 , and is used to detect the connection time between the second signal interface 212 and the first signal interface 112 .

After the second signal interface 212 is connected to the first signal interface 112 , the control chip 240 controls the timing device 260 to record the connection time between the second signal interface 212 and the first signal interface 112 , obtains the connection time, and compares the connection time with the preset time.

Optionally, the control chip 240 may determine whether the second signal interface 212 is connected to the first signal interface 112 by measuring the resistance of the second signal interface 212 , or may determine whether the second signal interface 212 is connected to the first signal interface 112 after receiving a specific signal.

Optionally, the preset time may be 3s, 4s, 5s, 6s, 7s, 8s, 9s, 10s or other time.

After the connection time is greater than the preset time, the control chip 240 controls the third power interface 211, the fourth power interface 213 to be connected to the first power interface 111, the second power interface 113, and the control chip 240 controls the second battery 230 to supply power to the first battery 150, and the power supply device 200 starts to charge the atomizer 100.

Therefore, in this embodiment, the connection stability between the power supply device 200 and the atomizer 100 can be determined by the connection time between the second signal interface 212 and the first signal interface 112, thereby further improving the connection safety between the power supply device 200 and the atomizer 100.

After the control chip confirms that the second circuit interface group is stably connected to the first circuit interface group, the control chip controls the second battery to charge the first battery, thereby enabling the power supply device to charge the atomizer.

Therefore, this embodiment can determine the connection stability between the power supply device and the atomizer through the detection information of the second circuit interface group, and after the connection between the power supply device and the atomizer is stable, the power supply device charges the atomizer. In this way, the connection safety between the power supply device and the atomizer is improved, and the charging stability of the atomizer is also improved.

The detection information of the second circuit interface group acquired by the control chip includes whether the second circuit interface receives a suction signal. The power supply device determines whether the power supply device and the atomizer are stably connected based on whether the suction signal is received.

S121: Detect whether the second circuit interface group receives a suction signal.

When the second circuit interface group receives the suction signal from the first circuit interface group, the control chip acquires the suction signal of the second circuit interface group and determines that the second circuit interface group has received the suction signal.

S122: If the second circuit interface group receives the suction signal, it is determined that the atomizer needs to be charged.

If the control chip learns based on the detection information that the second circuit interface group has received the suction signal, it is determined that the atomizer needs to be charged.

If the control chip learns based on the detection information that the second circuit interface group has not received the suction signal, it is determined that the atomizer is not charged.

After the airflow sensor detects the suction action, the airflow sensor generates a suction signal, and the airflow sensor sends the suction signal to the second circuit interface group through the first circuit interface group.

In this embodiment, the detection information of the second circuit interface group acquired by the control chip includes the number of times the second circuit interface receives the puff signal. The power supply device determines whether the power supply device and the atomizer are stably connected based on the number of times the puff signal is received.

S112: Record the number of times the second circuit interface group receives the suction signal.

When the second circuit interface group receives the puff signal from the first circuit interface group, the control chip obtains the puff signal of the second circuit interface group and records the puff signal of this time. The control chip starts recording from the first time when recording the received puff signal, and clears it after the power supply device is in the process of charging the atomizer.

S123: Determine whether the number of receptions is greater than a preset number.

After recording the suction signal of the second circuit interface group each time, the control chip compares the suction signal received by the second circuit interface group with the preset number of times to determine whether the number of times of receiving is greater than the preset number of times.

Optionally, the preset number of times may be 1 time, 2 times, 3 times, 4 times, 5 times, 6 times, 7 times, 8 times or other times.

S11: Acquire detection information of the second circuit interface group.

The control chip obtains the detection information of the second circuit interface group. In this embodiment, the detection information of the second circuit interface group obtained by the control chip includes the resistance value of the second signal interface. The power supply device determines whether the power supply device and the atomizer are stably connected based on the resistance value of the second signal interface received.

S125: Determine whether the resistance value of the second signal interface is equal to a preset resistance value.

The control chip compares the acquired resistance value of the second signal interface with the preset resistance value to determine whether the resistance value of the second signal interface is equal to the preset resistance value.

The preset resistance has a specific value. When the power supply device and the atomizer are separated, the second signal interface is in a suspended state, and the resistance of the second signal interface tends to infinity. When the power supply device and the atomizer are stably connected, the second signal interface and the first signal interface are stably connected, and the resistance of the second signal interface is a fixed preset resistance.
