[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] Figure 1 Shown is a schematic structural diagram of an electronic atomization device of related technology.

[0025] like Figure 1 As shown, the related art electronic atomization device 100 includes an electronic atomization device 10 and a charging device 20, wherein the charging device 20 is used to charge the electronic atomization device 10; wherein the electronic atomization device 10 includes a first controller 11, a first charging interface 12, a voltage divider circuit 13, a charging chip 14 and a battery ( Figure 1 (not shown), when the charging device 20 provides a charging voltage to the first charging interface 12, the charging voltage is divided by the voltage divider circuit 13 and then transmitted to the first controller 11, and then the first controller 11 wakes up the charging chip 14 according to the charging voltage, so that the charging chip 14 controls the battery charging. Since the electronic atomization device 10 is only provided with a first charging interface 12 but not with a communication interface, the electronic atomization device 10 cannot provide working data to the outside. In the process of implementing the present application, the inventor discovered that: since the first charging interface 12 of the electronic atomization device 10 is connected to the voltage divider circuit 13, if the first charging interface 12 is also used as a communication interface, the signal of the working data provided by the first controller 11 will first be divided by the voltage divider circuit 13 before it can be transmitted to the first charging interface 12, resulting in the signal amplitude of the working data transmitted to the first charging interface 12 being very small and unable to be acquired by an external device, for example, Figure 2 As shown, the signal amplitude of the working data is reduced to 70.21 mV after being divided by the voltage divider circuit 13, so that the electronic atomization device 10 cannot provide working data to the outside.

[0026] Based on this, the present application provides an electronic atomization device and an electronic atomization equipment, which can effectively solve the problem that the electronic atomization device cannot provide working data to the outside because the voltage divider circuit divides the signal of the working data of the electronic atomization device and reduces the signal amplitude of the working data. The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0027] Figure 3 Shown is a schematic structural diagram of an electronic atomization device according to an embodiment of the present application.

[0028] like Figure 3 As shown, the electronic atomization device 100 includes an electronic atomization device 10 and a charging device 20, and the charging device 20 is used to charge the electronic atomization device 10. Among them, the electronic atomization device 10 includes a first controller 11, a first charging interface 12 and a unidirectional conduction circuit 15. The first controller 11 is used to provide working data of the electronic atomization device 10, the first charging interface 12 is connected to the first controller 11 through a voltage divider circuit 13, and the unidirectional conduction circuit 15 is connected in parallel with the voltage divider circuit 13. Among them, the first controller 11 is used to transmit working data to the first charging interface 12 through the unidirectional conduction circuit 15, so that the working data bypasses the voltage divider circuit 13 and is transmitted to the first charging interface 12.

[0029] Exemplarily, the transmission process of the working data includes: when the first controller 11 outputs the working data, the unidirectional conduction circuit 15 is turned on under the action of the working data. Since the resistance value of the unidirectional conduction circuit 15 in the on state is much smaller than the resistance value of the voltage divider circuit 13, the working data can bypass the voltage divider circuit 13 and be directly transmitted to the first charging interface 12 through the unidirectional conduction circuit 15, so that the signal amplitude of the working data will not be greatly weakened. For example, Figure 4 As shown, after the working data is transmitted to the first charging interface 12 via the unidirectional conduction circuit 15, the signal amplitude is 1.63V.

[0030] The above scheme connects the unidirectional conduction circuit 15 in parallel to the voltage divider circuit 13 of the electronic atomization device 10, so that when the first controller 11 outputs the working data, the unidirectional conduction circuit 15 can be turned on under the action of the working data, and because the resistance value of the unidirectional conduction circuit 15 in the on state is much smaller than the resistance value of the voltage divider circuit 13, the working data can bypass the voltage divider circuit and be directly transmitted to the first charging interface 12 through the unidirectional conduction circuit 15, thereby avoiding the voltage divider circuit 13 from weakening the signal amplitude of the working data; and because the resistance value of the unidirectional conduction circuit 15 in the on state is very small, the unidirectional conduction circuit 15 has a very small voltage divider effect on the signal of the working data, which can ensure that the signal amplitude of the working data will not be greatly weakened and can be obtained by an external device. In this way, the electronic atomization device 10 can provide working data to the outside through the first charging interface 12, and the driving ability of the electronic atomization device 10 is enhanced.

[0031] In one embodiment, Figure 3 As shown, the voltage divider circuit 13 includes a first resistor R1 and a second resistor R2, a first end of the first resistor R1 is connected to the first controller 11, a second end of the first resistor R1 is connected to the first charging interface 12, a first end of the second resistor R2 is connected to the first end of the first resistor R1, and a second end of the second resistor R2 is grounded. Among them, the unidirectional conduction circuit 15 is connected in parallel with the first resistor R1.

[0032] In actual applications, the driving capability of the first controller 11 is relatively weak and cannot receive signals with higher amplitudes. For example, the first controller 11 cannot receive signals with amplitudes higher than 3V, while the driving capability of the external device is generally relatively strong. The external device can provide signals with amplitudes higher than 3V to the first charging interface 12. For example, the charging device 20 can provide a communication instruction with an amplitude of 5V to the first charging interface 12, and the communication instruction is used to enable the first controller 11 to provide working data to the outside. By setting a voltage divider circuit 13 composed of a first resistor R1 and a second resistor R2 between the first controller 11 and the first charging interface 12, the signal received by the first charging interface 12 can be first divided by the first resistor R1 and the second resistor R2 to ensure that the amplitude of the signal is reduced to the amplitude range that the first controller 11 can receive, and then the first controller 11 can receive it.

[0033] Correspondingly, if the working data provided by the first controller 11 is directly transmitted to the first charging interface 12 via the voltage divider circuit 13 composed of the first resistor R1 and the second resistor R2, the first resistor R1 and the second resistor R2 will also divide the signal of the working data before transmitting it to the first charging interface 12. However, due to the weak driving ability of the first controller 11, it is unable to provide working data with a large signal amplitude, so that after the working data is divided by the first resistor R1 and the second resistor R2, the signal amplitude of the working data becomes very small and insufficient to be acquired by an external device. In the above scheme, by connecting the unidirectional conduction circuit 15 in parallel to the two ends of the first resistor R1, the unidirectional conduction circuit 15 can be turned on under the action of the working data, and then the working data can bypass the first resistor R1 and be transmitted to the first charging interface 12 through the unidirectional conduction circuit 15, so as to provide working data to the outside.

[0034] In one embodiment, Figure 3 As shown, the unidirectional conduction circuit 15 includes a diode D. Exemplarily, the anode of the diode D is connected to one end of the first resistor R1 connected to the first controller 11, and the cathode of the diode D is connected to one end of the first resistor R1 connected to the first charging interface 12. This connection method can make the diode D conductive when the first controller 11 outputs working data, so as to transmit the working data provided by the first controller 11 to the first charging interface 12.

[0035] In one embodiment, Figure 3 As shown, the electronic atomization device 10 further includes a resistor-capacitor circuit 16, which includes a third resistor R3 and a capacitor C, wherein a first end of the third resistor R3 is connected to the first charging interface 12, a second end of the third resistor R3 is connected to a first end of the capacitor C, and a second end of the capacitor C is grounded. The capacitor C is in a fully charged state before the first controller 11 transmits working data to the first charging interface 12.

[0036] The inventors also found in the process of implementing this application that: Figure 1 As shown, in the related art, by connecting the RC circuit 16 to the first charging interface 12, when the charging device 20 is frequently plugged in and out of the first charging interface 12, the capacitor C in the RC circuit 16 can be used to absorb the spike pulse introduced by the charging device 20 frequently plugged in and out of the first charging interface 12; however, because the capacitor C in the RC circuit 16 has the function of charging and discharging, if the capacitor C is not fully charged before the first controller 11 transmits the working data to the first charging interface 12, and the signal frequency of the working data changes too fast, for example, when a level signal is used to represent the working data, the transition frequency between the high level and the low level is too fast, then the capacitor C in the RC circuit 16 cannot be fully charged in time, and then in the process of the first controller 11 transmitting the working data to the first charging interface 12, the signal amplitude of the working data will be lowered, causing the signal distortion of the working data provided to the outside.

[0037] Based on this, the above scheme sets the capacitor C to be in a fully charged state before the first controller 11 transmits the working data to the first charging interface 12, so as to avoid the signal amplitude of the working data being lowered and causing distortion of the signal amplitude of the working data during the process of the first controller 11 transmitting the working data to the first charging interface 12, which is beneficial to ensure that the electronic atomization device 10 provides working data with undistorted signal amplitude to the outside through the first charging interface 12.

[0038] In one embodiment, Figure 3 As shown, the electronic atomization device 10 further includes at least one of the following:

[0039] The battery 17 is connected to the first controller 11 so that the first controller 11 collects the voltage value of the battery 17;

[0040] The heating wire 18 is connected to the first controller 11 so that the first controller 11 collects the resistance value of the heating wire 18;

[0041] The working data includes at least one of a voltage value and a resistance value.

[0042] Exemplarily, the battery 17 includes but is not limited to a lithium battery, and the voltage value of the battery 17 includes an initial voltage value and a real-time voltage value of the battery 17 .

[0043] In the above scheme, by connecting the battery 17 and the heating wire 18 to the first controller 11, the first controller 11 can be used to collect the voltage value of the battery 17 and the resistance value of the heating wire 18, and then the first controller 11 can provide the voltage value of the battery 17 and the resistance value of the heating wire 18 to the outside through the first charging interface 12, which is beneficial for an external device to monitor the battery 17 voltage and the heating state of the heating wire 18 of the electronic atomization device 10.

[0044] In one embodiment, Figure 3 As shown, the first charging interface 12 is also used to access the charging voltage. The electronic atomization device 10 also includes a charging chip 14, which is connected to the first controller 11 and the battery 17 respectively. The first controller 11 is also used to wake up the charging chip 14 when receiving the charging voltage, so that the charging chip 14 controls the charging of the battery 17. The charging voltage can be provided by the charging device 20. Based on this, when the first controller 11 receives the charging voltage, the charging chip 14 can be automatically awakened, so that the charging chip 14 automatically controls the charging of the battery 17.

[0045] The present application also provides an electronic atomization device, such as Figure 3 As shown, the electronic atomization device 100 includes the electronic atomization device 10 of any one of the above embodiments and a charging device 20, and the charging device 20 is used to charge the electronic atomization device 10. The charging device 20 includes a second controller 21 and a second charging interface 22, and the second controller 21 is connected to the first charging interface 12 through the second charging interface 22 to receive working data.

[0046] Exemplarily, the second controller 21 is electrically connected to the second charging interface 22, and the second charging interface 22 is electrically connected to the first charging interface 12, so that the second controller 21 can receive the working data provided by the first charging interface 12 through the second charging interface 22, and use an external device to obtain the working data of the electronic atomization device 10. In this way, the charging device 20 can not only have the function of charging the electronic atomization device 10, but also have the function of receiving the working data of the electronic atomization device 10.

[0047] In one embodiment, Figure 3 As shown, the electronic atomization device 10 has a resistor-capacitor circuit 16 connected to the first charging interface 12. The structure and working principle of the resistor-capacitor circuit 16 can be referred to the above embodiments, and will not be described here.

[0048] The second controller 21 is also used to provide a high level lasting at least as long as the charging time of the capacitor C in the RC circuit 16 to the first charging interface 12 through the second charging interface 22 before receiving the working data, so as to charge the capacitor C to a fully charged state.

[0049] Exemplarily, the charging time of the capacitor C may be 800ms, the duration of the high level may be 1s, and the second charging interface 22 is electrically connected to the first charging interface 12. Before receiving the working data, the second controller 21 provides a high level with a duration of 1s to the first charging interface 12 through the second charging interface 22, so that the capacitor C in the resistor-capacitor circuit 16 can be fully charged, so that the capacitor C is in a fully charged state.

[0050] Based on this, before the first controller 11 transmits working data to the second controller 21, it can ensure that the capacitor C in the resistor-capacitor circuit 16 is in a fully charged state. In this way, in the process of transmitting working data from the first controller 11 to the second controller 21, it can be avoided that the signal amplitude of the working data is lowered due to insufficient charging of the capacitor C in the resistor-capacitor circuit 16, thereby causing the problem of distortion of the signal amplitude of the working data. This is beneficial to ensure that the second controller 21 receives working data with undistorted signal amplitude.

[0051] In one embodiment, Figure 3 As shown, the charging device 20 also includes a power module 23 and a pull-up resistor R4. The power module 23 is connected to the second charging interface 22 through the pull-up resistor R4 to increase the signal amplitude of the working data so that the second controller 21 receives the working data with the signal amplitude increased.

[0052] For example, please refer to Figure 4 In the case where the charging device 20 is not provided with the power module 23 and the pull-up resistor R4, since the driving capability of the first controller 11 is weaker than that of the second controller 21, the signal amplitude of the working data provided by the first controller 11 through the first charging interface 12 is 1.63V, and in the process of transmitting the working data from the first controller 11 to the first charging interface 12, the capacitor C in the resistor-capacitor circuit 16 will be charged and discharged under the action of the signal of the working data, which will affect the signal integrity of the working data and cause the signal of the working data to be distorted, for example, the signal waveform of the working data is a triangular wave instead of a square wave.

[0053] In the above scheme, the charging device 20 includes a power module 23 and a pull-up resistor R4, and the power module 23 is connected to the second charging interface 22 through the pull-up resistor R4. This structure can increase the signal amplitude of the working data when the working data is transmitted to the second charging interface 22. For example, Figure 4 and Figure 5 As shown, the signal amplitude of the working data can be increased from 1.63V to 3.75V to increase the signal amplitude of the working data and make the signal waveform of the working data more square. For example, the working data is a square wave. This can reduce the impact of the capacitor C in the RC circuit 16 being charged and discharged under the action of the working data signal on the signal integrity of the working data, ensure that the signal of the working data is received by the second controller 21 without distortion, and prevent the loss of working data. For example, when the working data is transmitted from the first controller 11 to the second controller 21 in the form of a data packet, packet loss is prevented, which is more helpful to enhance the driving capability of the second controller 21.

[0054] In one embodiment, Figure 3As shown, the power module 23 includes a rectifier circuit 231 and a boost circuit 232. The rectifier circuit 231 is used to convert AC power into DC power, wherein the AC power can be a mains power supply; the boost circuit 232 is connected between the rectifier circuit 231 and the pull-up resistor R4 to boost the DC power and transmit it to the second charging interface 22 through the pull-up resistor R4. By arranging the boost circuit 232 between the rectifier circuit 231 and the second charging interface 22, the boost circuit 232 can be used to increase the voltage of the DC power output by the rectifier current to provide the DC power with the increased voltage to the second charging interface 22. It should be noted that the voltage increase multiple of the DC power by the boost circuit 232 can be selected and adjusted according to actual needs, as long as it meets the requirements of the second charging interface 22, and the embodiment of the present application does not limit this.

[0055] In one embodiment, Figure 3 As shown, the first controller 11 is connected to the first charging interface 12 via the first power cord 111, and the second controller 21 is connected to the second charging interface 22 via the second power cord 211. The first charging interface 12 and the second charging interface 22 are plugged together so that the first power cord 111 and the second power cord 211 are overlapped, and the overlapped first power cord 111 and second power cord 211 also serve as a communication line for single-line communication between the first controller 11 and the second controller 21.

[0056] Exemplarily, the first charging interface 12 may be a USB male connector, the first power cord 111 is connected to the power supply end of the USB male connector, the second charging interface 22 may be a USB female connector, the second power cord 211 is connected to the power supply end of the USB female connector, and the first power cord 111 and the second power cord 211 can be overlapped by plugging the USB male connector and the USB female connector, so that the second controller 21 can provide a charging voltage to the first controller 11. In addition, the overlapped first power cord 111 and the second power supply can also serve as a communication line for single-line communication between the first controller 11 and the second controller 21. Based on this, the electronic atomization device 10 can provide working data to the charging device 20 without changing the connection structure between the electronic atomization device 10 and the charging device 20, which is conducive to reducing the manufacturing cost.

[0057] It should be noted that the electronic atomization device 100 provided in the embodiment of the present application adopts all the technical solutions of all the embodiments of the above-mentioned electronic atomization device 10, and therefore has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
