[0002] In electronic atomization devices, dual atomizers are often used. If the two atomizers use different atomized liquids, it is necessary to identify the two atomizers.

The illustrative representations of the above terms do not necessarily refer to the same embodiment or example.

[0038] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0039] In electronic atomization devices, dual atomizers are frequently used. If the two atomizers use different atomized liquids or require different power outputs, it is necessary to identify the two atomizers. However, since the atomizers are inserted symmetrically into the battery holder, it is also necessary to identify the insertion direction to determine the corresponding atomizer and control the correct use of both atomizers.

[0040] Based on this, this application provides a battery rod, which includes: a detection and identification device, a first switching transistor, a second switching transistor, a third switching transistor, and four contacts. The first contact is grounded (GND), the second contact is connected to the power supply through the first switching transistor, the third contact is connected to the power supply through the second switching transistor (PMOS2), and the fourth contact is grounded through the third switching transistor. The detection and identification device is connected to the second contact and / or the third contact. When the battery rod is connected to an atomizing device, one atomizer in the atomizing device is connected between the first contact and the second contact, and another atomizer in the atomizing device is connected between the third contact and the fourth contact. The first and second switching transistors are PMOS transistors, and the third switching transistor is an NMOS transistor. The detection and identification device can be a general voltage detection module, a microcontroller (MCU), or a processor, as long as it can perform voltage detection. By connecting the detection and identification device to the second and / or third contacts in the battery rod to detect the corresponding voltage, the connection method between the battery rod and the atomizing device is identified based on the detected voltage. This enables accurate identification of the two atomizers connected to the battery rod, which is helpful for the use and control of the atomizers.

[0041] In this embodiment, since the atomizing device includes dual atomizers, when the battery rod is connected to the atomizing device, one atomizer is connected between the first and second contacts, and the other atomizer is connected between the third and fourth contacts. Because the atomizing device is symmetrical, it is impossible to identify which atomizer is connected between the first and second contacts or between the third and fourth contacts. If the two atomizers have different power outputs during normal use, or if the atomized liquids in the two atomizers are different, it is necessary to identify the two atomizers before applying matching power or using the matching atomizer to ensure the correct use of the atomizing device.

[0042] like Figure 1 As shown, the first contact 5 is grounded (GND), the second contact 6 is connected to the power supply (Power) through the first switching transistor (PMOS1), the third contact 7 is connected to the power supply (Power) through the second switching transistor (PMOS2), and the fourth contact 8 is grounded (GND) through the third switching transistor (NMOS). The detection and identification device is connected to the second contact 6. A first resistor (RES1) can be connected in series between the detection and identification device and the second contact 6. This first resistor (RES1) can limit current and filter out high-frequency stray waves in the circuit. When the battery rod is connected to the atomizing device, the first contact 5 and the second contact 6 are conductive, and the third contact 7 and the fourth contact 8 are conductive. By detecting the voltage at the second contact 6 when the second switching transistor (PMOS2) is conductive, it can be determined whether the battery rod and the atomizing device are connected in a forward or reverse direction. This allows it to determine the atomizer connected between the first contact 5 and the second contact 6, and between the third contact 7 and the fourth contact 8.

[0043] like Figure 2 As shown, with Figure 1 The only difference is that the detection and identification device is connected to the third contact 7. A second resistor RES2 can be connected in series between the detection and identification device and the third contact 7. This second resistor RES2 can limit current and filter out high-frequency stray waves in the circuit. When the battery rod is connected to the atomizing device, the first contact 5 and the second contact 6 are conductive, and the third contact 7 and the fourth contact 8 are conductive. By detecting the voltage at the third contact 7 when the second switching transistor PMOS2 is turned on, it can be determined whether the battery rod and the atomizing device are connected in the forward or reverse direction. This allows it to determine the atomizer connected between the first contact 5 and the second contact 6, and between the third contact 7 and the fourth contact 8.

[0044] Furthermore, such as Figure 3 As shown, in Figure 2Based on this, the battery rod can also include a measuring resistor RES3, which is connected in parallel across the second switching transistor PMOS2. When the second switching transistor PMOS2 is off, the measuring resistor RES3 is connected to the circuit, and the battery rod and the atomizing device are connected in either the forward or reverse direction. The voltage difference at the third contact 7 is even greater, so by detecting the voltage at the third contact 7, the connection status between the battery rod and the atomizing device can be accurately detected.

[0045] In other embodiments of this application, the detection and identification device may be configured to be connected to both the second contact 6 and the third contact 7 simultaneously. See also Figure 4 The first contact 5 is grounded (GND), the second contact 6 is connected to the power supply via the first switching transistor PMOS1, the third contact 7 is connected to the power supply via the second switching transistor PMOS2, and the fourth contact 8 is grounded (GND) via the third switching transistor NMOS. The detection and identification device can be configured to connect to both the second contact 6 and the third contact 7 simultaneously. The forward or reverse connection of the battery rod and the atomizing device can be determined by simultaneously detecting the voltages of the second contact 6 and the third contact 7. The determination method is the same as before and will not be repeated here. Additionally, a first resistor RES1 can be connected in series between the detection and identification device and the second contact 6, and a second resistor RES2 can be connected in series between the detection and identification device and the third contact 7. The first resistor RES1 and the second resistor RES2 can limit current and filter out high-frequency stray waves in the circuit.

[0046] The battery poles are symmetrically arranged, therefore the battery poles can also be used in, for example Figure 5 The connection method is shown. The first contact a is connected to the power supply POWER via the first switching transistor PMOS1, the second contact b is grounded (GND), the third contact c is grounded (GND) via the third switching transistor NMOS, and the fourth contact d is connected to the power supply POWER via the second switching transistor PMOS2. The first contact a is also connected to a detection and identification device. This battery rod and atomizing device can be identified as being connected in either the forward or reverse direction by detecting the voltage at the first contact a when the second switching transistor PMOS2 is turned on. A first resistor RES1 can also be connected between the detection and identification device and the first contact a. It should be noted that in other embodiments of this application, the detection and identification device can be connected to the fourth contact d, or simultaneously to both the first contact a and the fourth contact d. Figure 5 The battery rod and Figure 1 Compared to the middle, it is equivalent to, Figure 5 The first contact a, the second contact b, the third contact c, and the fourth contact d in the diagram are respectively equivalent to Figure 1 The second contact 6, the first contact 5, the fourth contact 8, and the third contact 7 in the middle are equivalent to rotating 180 degrees.

[0047] The battery rod of this application embodiment includes: a detection and identification device, a first switch tube, a second switch tube, a third switch tube, and four contacts. The first contact is grounded, the second contact is connected to the power supply through the first switch tube, the third contact is connected to the power supply through the second switch tube, and the fourth contact is grounded through the third switch tube. The detection and identification device is connected to the second contact and / or the third contact. When the battery rod is connected to an atomizing device, one atomizer in the atomizing device is connected between the first contact and the second contact, and the other atomizer in the atomizing device is connected between the third contact and the fourth contact. The detection and identification device is connected to the second contact and / or the third contact in the battery rod to detect the corresponding voltage. The connection method between the battery rod and the atomizing device is identified based on the detected voltage, thereby enabling accurate identification of the two atomizers connected to the battery rod, which is helpful for the use and control of the atomizers.

[0048] This application also provides an electronic atomizing device, including: an atomizing apparatus and... Figures 1-5 The device includes any of the battery rods in the atomizing unit. The atomizing device comprises a first atomizer, a second atomizer, and a one-way switch. The first atomizer includes a first heating wire and a first atomizing liquid, the first heating wire being used to heat the first atomizing liquid. The second atomizer includes a second heating wire and a second atomizing liquid, the second heating wire being used to heat the second atomizing liquid. The one-way switch is connected in series between the first and second heating wires. When the battery rod is connected to the atomizing device, the battery rod and the atomizing device can be connected in either reverse or forward. Since the battery rod and the atomizing device are symmetrically arranged, it is not visually possible to distinguish whether the battery rod and the atomizing device are connected in the forward or reverse direction. Therefore, before using the electronic atomizing device, the second switch can be turned on, and the voltage of each contact in the battery rod can be detected. Based on the detected voltage, it can be determined whether the battery rod and the atomizing device are connected in the forward or reverse direction, thereby identifying the first and second atomizers. Only then can the first or second atomizer be used at the corresponding power.

[0049] In this application embodiment, the packaging of the atomizing device is described in detail below. Figure 6 The atomizing device includes a first atomizer and a second atomizer, which are respectively isolated from each other. The operating power of the first atomizer and the second atomizer may be different. The flavors of the atomized liquid in the first atomizer and the atomized liquid in the second atomizer may also be different, or the atomized liquids in the two atomizers may have different functions, etc., without specific limitations. However, it is necessary to first determine which atomizer needs to be used before using it accurately and appropriately.

[0050] The structure of the atomizing device is as follows Figure 7As shown, the cathode of diode D1 is connected to the second end 1 of the first heating wire L1, and the anode of diode D1 is connected to the second end 4 of the second heating wire L2.

[0051] The structure of the atomizing device can also be as follows: Figure 8 As shown, the cathode of diode D1 is connected to the first end 3 of the second heating wire L2, and the anode of diode D1 is connected to the first end 1 of the first heating wire L1.

[0052] The voltage across diode D1 when it is turned on is very low. For example, when the diode is silicon, the forward voltage drop is about 0.7V, and when the diode is germanium, the forward voltage drop is about 0.3V.

[0053] The atomizing device is detachably or rotatably connected to the battery rod. Thus, when the atomizing device is connected to the battery rod, the first and second ends of the first heating wire, and the first and second ends of the second heating wire, are respectively connected to the four contacts of the battery rod. Specifically, one of the first and second heating wires is connected between the first and second contacts of the battery rod, and the other of the first and second heating wires is connected between the third and fourth contacts of the battery rod. The atomizing device and the battery rod can be in either a first connection state or a second connection state. The first connection state indicates a forward connection between the atomizing device and the battery rod, and the second connection state indicates a reverse connection. Of course, in other embodiments of this application, the first connection state may also indicate a reverse connection between the atomizing device and the battery rod, and the second connection state may indicate a forward connection between the atomizing device and the battery rod.

[0054] The following is Figure 1 The battery rod and Figure 8 The following explanation uses the atomizing device combination as an example.

[0055] Taking the first connection state as an example of the atomizing device and the battery rod being connected in a forward orientation, in this first connection state, the first contact is connected to the first end of the first heating wire, the second contact is connected to the second end of the first heating wire, the third contact is connected to the first end of the second heating wire, and the fourth contact is connected to the second end of the second heating wire. That is, when the battery rod and the atomizing device are connected in a forward orientation, the connections between the four contacts of the battery rod and the four ends of the atomizing device are as follows: Figure 9 As shown, the first contact 5 of the battery rod is connected to the first end 1 of the first heating wire in the atomizing device; the second contact 6 of the battery rod is connected to the second end 2 of the first heating wire in the atomizing device; the third contact 7 of the battery rod is connected to the first end 1 of the second heating wire in the atomizing device; and the fourth contact 8 of the battery rod is connected to the second end 4 of the second heating wire in the atomizing device. See the corresponding connection diagram. Figure 11 .

[0056] Correspondingly, in the second connection state, the first contact is connected to the second end of the second heating wire, the second contact is connected to the first end of the second heating wire, the third contact is connected to the second end of the first heating wire, and the fourth contact is connected to the first end of the first heating wire. Specifically, when the battery rod and the atomizing device are connected in the correct orientation, the connections of the four contacts of the battery rod to the four ends of the atomizing device are as follows: Figure 10 As shown, the first contact 5 of the battery rod is connected to the second end 8 of the second heating wire in the atomizing device; the second contact 6 of the battery rod is connected to the first end 3 of the second heating wire in the atomizing device; the third contact 7 of the battery rod is connected to the second end 2 of the first heating wire in the atomizing device; and the fourth contact 8 of the battery rod is connected to the first end 1 of the first heating wire in the atomizing device. See the corresponding connection diagram. Figure 12 .

[0057] Before using an e-cigarette device, it is necessary to identify the battery and atomizing mechanism within the device. Figure 11 The forward connection in the middle is still like Figure 12 The forward connection in the device. To identify whether the battery rod and atomizing device in the electronic atomizer are connected in the forward or reverse direction, the second switch PMOS2 can be turned on. The first contact 5 and the second contact 6 are connected through the first heating wire or the second heating wire, and the third contact 7 and the fourth contact 8 are connected through the second heating wire or the first heating wire. The resistance of the first heating wire and the second heating wire is very small, for example, 0.5Ω-1.5Ω. If it is Figure 11 In the forward connection shown, diode D1 is cut off, and the detection and identification device, the heating wire connected between the first contact 5 and the second contact 6, and diode D1 do not form a circuit; therefore, the first contact 5 and the second contact 6 are at a low level. If... Figure 12 In the reverse connection shown, when the second switch PMOS2 is turned on, the diode D1 is also turned on. At this time, the second switch PMOS2, the second heating wire L2, the diode D1, and the first heating wire L1 form a circuit. Since the voltage is very low when the second switch PMOS2 and the diode D1 are turned on, it can be ignored. Thus, the voltage at the second contact 6 is half of the power supply, which is a high level.

[0058] Therefore, based on the voltage at the second contact 6 when the second switch PMOS2 is turned on, it can be determined whether the battery rod and the atomizing device are connected in the forward or reverse direction. If the second contact 6 is detected to be low, it indicates a forward connection between the battery rod and the atomizing device, thus identifying the connection between the first contact 5 and the second contact 6 as the first atomizer, and the connection between the third contact 7 and the fourth contact 8 as the second atomizer. If the second contact 6 is detected to be high, it indicates a reverse connection between the battery rod and the atomizing device, thus identifying the connection between the first contact 5 and the second contact 6 as the second atomizer, and the connection between the third contact 7 and the fourth contact 8 as the first atomizer.

[0059] In this embodiment of the application, when the detection and identification device is connected to the third contact 7, that is... Figure 2 The battery rod shown is Figure 8 The atomizing device in the middle is connected to obtain such Figure 13 and Figure 14 The electronic atomizing device shown, in which Figure 13 The battery rod and atomizer are connected in the forward direction. Figure 14 The battery rod is connected to the atomizing device in reverse.

[0060] To determine whether the battery bar and atomizing device in an electronic atomizer are connected in the forward or reverse direction, the second switch PMOS2 can be turned on. If it is... Figure 13 In the forward connection shown, diode D1 is off, the third NMOS switch is off, the second PMOS switch and the heating wire connected between the third contact 7 and the fourth contact 8 do not form a circuit, and the third contact 7 and the fourth contact 8 are at a high level, equal to the power supply voltage. If it is... Figure 14 In the reverse connection shown, when the second switch PMOS2 is turned on, the diode D1 is also turned on. At this time, the second switch PMOS2, the second heating wire L2, the diode D1, and the first heating wire L1 form a circuit. Since the forward voltage drop of the diode D1 is very low when the second switch PMOS2 and the diode D1 are turned on, it can be ignored. Thus, the voltage at the third contact 7 is less than the power supply voltage.

[0061] Therefore, based on the conduction of the second switch PMOS2, the voltage at the third contact 7 can be used to identify whether the battery rod and the atomizing device are connected in the forward or reverse direction. If the voltage at the third contact 7 is the power supply voltage, the battery rod and the atomizing device are identified as being connected in the forward direction. This further indicates that the first atomizer is connected between the first contact 5 and the second contact 6, and the second atomizer is connected between the third contact 7 and the fourth contact 8. If the voltage at the third contact 7 is less than the power supply voltage, the battery rod and the atomizing device are identified as being connected in the reverse direction. This further indicates that the second atomizer is connected between the first contact 5 and the second contact 6, and the first atomizer is connected between the third contact 7 and the fourth contact 8.

[0062] To more accurately identify the connection method between the battery rod and the atomizing device in electronic atomizing devices, use... Figure 3 The battery rod is connected to the atomizing device, and a measuring resistor RES3 is connected in parallel across the two ends of the second switching transistor PMOS2. The resistance of the measuring resistor RES3 is much greater than the resistance of the first heating wire L1 and the second heating wire L2. Preferably, the resistance of the measuring resistor RES3 is above 470KΩ.

[0063] The forward and reverse connections of the battery rod and the atomizing device in an electronic atomizing device are as follows: Figure 15 and Figure 16 As shown. If it is Figure 15 The forward connection shown controls the second switch PMOS2 to be off, the measuring resistor RES3 is connected to the circuit, the diode D1 is off, the measuring resistor RES3 and the heating wire connected between the third contact 7 and the fourth contact 8 do not form a circuit, the third contact 7 and the fourth contact 8 are at a high level, and equal to the power supply voltage. If it is Figure 16 In the reverse connection shown, the second switch PMOS2 is off, the measuring resistor RES3 is connected to the circuit, and the diode D1 is on. At this time, the measuring resistor RES3, the second heating wire L2, the diode D1, and the first heating wire L1 form a circuit. Since the measuring resistor RES3 has a very large resistance, it is determined to be greater than the resistance of the first heating wire L1 and the second heating wire L2. When the diode D1 is on, the forward voltage drop of the diode D1 is very low and can be ignored. Thus, the voltage at the third contact 7 is low.

[0064] Therefore, based on the condition that the second switch PMOS2 is off, the voltage at the third contact 7 can be used to identify whether the battery rod and the atomizing device are connected in the forward or reverse direction. If the voltage at the third contact 7 is the power supply voltage, the battery rod and the atomizing device are identified as being connected in the forward direction. This further indicates that the first atomizer is connected between the first contact 5 and the second contact 6, and the second atomizer is connected between the third contact 7 and the fourth contact 8. If the voltage at the third contact 7 is low, the battery rod and the atomizing device are identified as being connected in the reverse direction. This further indicates that the second atomizer is connected between the first contact 5 and the second contact 6, and the first atomizer is connected between the third contact 7 and the fourth contact 8.

[0065] When the second switch PMOS2 is turned on, because the resistance of the measuring resistor RES3 is very large while the on-resistance of the second switch PMOS2 is very small, the branch containing the measuring resistor RES3 will be short-circuited. If the third switch NMOS is turned on, the second switch PMOS2, the heating wire between the third contact 7 and the fourth contact 8, and the third switch NMOS form a circuit to heat the heating wire between the third contact 7 and the fourth contact 8, and the atomizer corresponding to the heating wire between the third contact 7 and the fourth contact 8 will operate. If the first switch PMOS is turned on, the first switch PMOS and the heating wire between the first contact 5 and the second contact 6 form a circuit to heat the heating wire between the first contact 5 and the second contact 6, and the atomizer corresponding to the heating wire between the first contact 5 and the second contact 6 will operate.

[0066] This application also provides a dual atomizer identification method, such as Figure 2 As shown, Figure 2 This is a schematic flowchart illustrating a dual atomizer identification method provided in an embodiment of this application. This dual atomizer identification method is applicable to electronic atomization devices and includes:

[0067] Step S11: Control the second switch to turn on, and detect the first voltage of the second contact and / or the second voltage of the third contact.

[0068] In this embodiment, if the detection and identification device in the battery rod of the electronic atomizing device is connected to the second contact, the connection method between the battery rod and the atomizing device in the electronic atomizing device is identified by detecting the first voltage at the second contact when the second switching transistor PMOS2 is turned on.

[0069] If the detection and identification device in the battery bar of the electronic atomizing device is connected to the third contact, the connection method between the battery bar and the atomizing device in the electronic atomizing device can be identified by detecting the second voltage at the third contact when the second switch PMOS2 is turned on.

[0070] If the detection and identification device in the battery module of the electronic atomizing device is connected to both the second and third contacts, the voltage at both contacts can be detected simultaneously when the second switching transistor PMOS2 is turned on, thus identifying the connection method between the battery module and the atomizing device. Alternatively, only the voltage at the second or third contact can be detected to identify the connection method.

[0071] It should be noted that although the battery rod and the atomizing device are symmetrically arranged, their structures are clear; the only uncertainty lies in how they are connected.

[0072] Step S12: Identify the first atomizer and the second atomizer based on the first voltage and / or the second voltage.

[0073] If the first voltage is high and / or the second voltage is high, the atomizing device and the battery are identified as being in a first connection state. If the first voltage is low and / or the second voltage is low, the atomizing device and the battery are identified as being in a second connection state, which is the opposite of the first connection state. The first connection state can be either a forward connection or a reverse connection; correspondingly, the second connection state can be either a reverse connection or a forward connection. That is, this application does not specifically limit the first and second connection states, but if one is a forward connection, then the other is a reverse connection.

[0074] In this embodiment of the application, it is assumed that the first connection state is a forward connection and the second connection state is a reverse connection, so that the electronic atomization device includes Figure 1 The battery rod and Figure 8 The atomizing device in the middle is used as an example for explanation.

[0075] If the detection and identification device in the battery bar of the electronic atomizing device is connected to the second contact and detects a low voltage at the second contact, it can be identified that the battery bar and the atomizing device are connected in the forward direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the first atomizer, and the connection between the third contact 7 and the fourth contact 8 is the second atomizer. If the detected first voltage at the second contact is high, it can be identified that the battery bar and the atomizing device are connected in the reverse direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the second atomizer, and the connection between the third contact 7 and the fourth contact 8 is the first atomizer.

[0076] If the detection and identification device in the battery bar of the electronic atomizing device is connected to the third contact, and the second voltage at the third contact is detected as the power supply voltage when the second switch PMOS2 is turned on, it can be identified that the battery bar and the atomizing device are connected in a forward direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the first atomizer, and the connection between the third contact 7 and the fourth contact 8 is the second atomizer. If the detected first voltage at the third contact is less than the power supply voltage, it can be identified that the battery bar and the atomizing device are connected in a reverse direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the second atomizer, and the connection between the third contact 7 and the fourth contact 8 is the first atomizer.

[0077] If the detection and identification device in the battery module of the e-cigarette device is connected to both the second and third contacts, the voltage at both contacts can be detected simultaneously when the second switching transistor PMOS2 is turned on, thus identifying the connection method between the battery module and the atomizing device. Alternatively, only the voltage at the second or third contact can be detected to identify the connection method. The specific identification method is the same as before and will not be repeated here.

[0078] Electronic atomization devices include Figure 3 The battery rod and Figure 8 The atomizing device in the middle is used as an example for explanation.

[0079] If the detection and identification device in the battery bar of the electronic atomizing device is connected to the third contact, and the second voltage at the third contact is detected as the power supply voltage when the second switch PMOS2 is turned on, it can be identified that the battery bar and the atomizing device are connected in a forward direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the first atomizer, and the connection between the third contact 7 and the fourth contact 8 is the second atomizer. If the detected first voltage at the third contact is low, it can be identified that the battery bar and the atomizing device are connected in a reverse direction. Therefore, it can be identified that the connection between the first contact 5 and the second contact 6 is the second atomizer, and the connection between the third contact 7 and the fourth contact 8 is the first atomizer.

[0080] If the detection and identification device in the battery bar of the electronic atomizing device is connected to the second contact, the identification method is the same as before and will not be repeated.

[0081] The dual atomizer identification method of this application embodiment controls the second switch tube to conduct, detects the first voltage of the second contact, and / or the second voltage of the third contact; identifies the first atomizer and the second atomizer based on the first voltage and / or the second voltage, thus enabling accurate identification of the two atomizers connected to the battery rod, which is helpful for the use and control of the atomizers.
