[0046] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0047] Figure 1 This is a schematic diagram of the structure of an atomizing device provided in an embodiment of this application. Please refer to it. Figure 1The atomizing device includes: a mouthpiece 1, a first conduction signal generating circuit 2, a second conduction signal generating circuit 3, a third conduction signal generating circuit 4, a first switching circuit 5, a first heating circuit 6, a second switching circuit 7, and a second heating circuit 8; wherein the heating power of the first heating circuit 6 and the second heating circuit 8 is different. A sensing module 11 is installed inside the mouthpiece 1. The sensing module 11 outputs a corresponding electrical signal based on the contact area of the mouthpiece 1, and the magnitude of the electrical signal is positively correlated with the contact area of the mouthpiece 1. The first conduction signal generating circuit 2 generates a first conduction signal when the electrical signal is within a first range value; the second conduction signal generating circuit 3 generates a second conduction signal when the electrical signal is within a second range value; and the third conduction signal generating circuit 4 generates a third conduction signal when the electrical signal is within a third range value. The input terminal of the first switching circuit 5 is connected to the first conduction signal generating circuit 2 and the third conduction signal generating circuit 4, respectively. The output of the first switching circuit 5 is connected to the first heating circuit 6; the input of the second switching circuit 7 is connected to the second conduction signal generation circuit 3 and the third conduction signal generation circuit 4 respectively, and the output of the second switching circuit 7 is connected to the second heating circuit 8; wherein, the first switching circuit 5 can be turned on by the first conduction signal to make the first heating circuit 6 work; the second switching circuit 7 can be turned on by the second conduction signal to make the second heating circuit 8 work; the first switching circuit 5 and the second switching circuit 7 can be turned on by the third conduction signal to make the first heating circuit 6 work and the second heating circuit 8 work.
[0048] When the atomizing device is used, the mouthpiece 1 will come into contact with the user's lips to perform inhalation. When the mouthpiece 1 is in contact, its built-in sensing module 11 will sense the contact area and output a corresponding electrical signal. The magnitude of the output electrical signal is positively correlated with the contact area of the mouthpiece 1. That is, the larger the contact area of the mouthpiece 1, the larger the electrical signal output by the sensing module 11, and the smaller the contact area of the mouthpiece 1, the smaller the electrical signal output by the sensing module 11.
[0049] As an example, when the area of the nozzle 1 in contact accounts for 30% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is X; when the area of the nozzle 1 in contact accounts for 60% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is Y; when the area of the nozzle 1 in contact accounts for 100% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is Z; where Z is greater than Y and greater than X.
[0050] In some embodiments, to facilitate the sensing module 11 in outputting a corresponding electrical signal based on the contact area of the suction nozzle 1, and to facilitate suction by the user, please refer to... Figure 2The nozzle 1 may include: a first segment 12, the diameter of which is a first diameter; and a second segment 13, which is perpendicularly connected to the first segment 12, the diameter of which is a second diameter, which is larger than the first diameter.
[0051] Additionally, in some embodiments, please refer to Figure 2 The nozzle 1 may also include a third section 14, which is located between the first section 12 and the second section 13, and the diameter of the third section 14 gradually increases from the first section 12 to the second section 13.
[0052] Therefore, the sensing module 11 can output an electrical signal of corresponding magnitude based on whether the first segment 12, the second segment 13, and the third segment 14 of the nozzle 1 are in contact. For example, if the first segment 12 of the nozzle 1 is in contact, it means that the contacted area of the nozzle 1 may account for 30% of the nozzle 1's area; in this case, the sensing module 11 can output an electrical signal of magnitude X. If the first segment 12 and the third segment 14 of the nozzle 1 are in contact, it means that the contacted area of the nozzle 1 may account for 60% of the nozzle 1's area; in this case, the sensing module 11 can output an electrical signal of magnitude Y. If all three segments of the nozzle 1 are in contact, it means that the contacted area of the nozzle 1 may account for 100% of the nozzle 1's area; in this case, the sensing module 11 can output an electrical signal of magnitude Z. Where Z is greater than Y, which is greater than X.
[0053] It should be noted that the above description assumes a positive correlation between the magnitude of the electrical signal and the area of the suction nozzle 1 in contact. Alternatively, in application, the magnitude of the electrical signal can also be negatively correlated with the area of the suction nozzle 1 in contact; that is, the larger the area of the suction nozzle 1 in contact, the smaller the electrical signal output by the sensing module 11, and vice versa. In other words, this embodiment does not limit the correlation between the magnitude of the electrical signal and the area of the suction nozzle 1 in contact.
[0054] Furthermore, the above description assumes that the suction nozzle 1 includes the first segment 12, the second segment 13, and the third segment 14. Alternatively, in application, the suction nozzle 1 may have other shapes. This application does not limit this aspect.
[0055] After the sensing module outputs an electrical signal, the first conduction signal generation circuit 2, the second conduction signal generation circuit 3, and the third conduction signal generation circuit 4 determine whether to generate the corresponding conduction circuit based on the magnitude of the electrical signal. That is, when the electrical signal is within a first range, the first conduction signal generation circuit 2 can generate a first conduction signal; if the electrical signal is outside the first range, the first conduction signal generation circuit 2 cannot generate a first conduction signal. When the electrical signal is within a second range, the second conduction signal generation circuit 3 can generate a second conduction signal; if the electrical signal is outside the second range, the second conduction signal generation circuit 3 cannot generate a second conduction signal. When the electrical signal is within a third range, the third conduction signal generation circuit 4 can generate a third conduction signal; if the electrical signal is outside the third range, the third conduction signal generation circuit 4 cannot generate a third conduction signal.
[0056] As an example, suppose the first range is A to B, the second range is C to D, and the third range is E to F, and the received electrical signal is X. If X is between A and B, then the first conduction signal generation circuit 2 will generate the first conduction signal, while the second conduction signal generation circuit 3 and the third conduction signal generation circuit 4 will not generate conduction signals; if X is between C and D, then the second conduction signal generation circuit 3 will generate the second conduction signal, while the first conduction signal generation circuit 2 and the third conduction signal generation circuit 4 will not generate conduction signals; if X is between E and F, then the third conduction signal generation circuit 4UI will generate the third conduction signal, while the first conduction signal generation circuit 2 and the second conduction signal generation circuit 3 will not generate conduction signals.
[0057] It should be noted that the first, second, and third range values described above are merely illustrative examples, and in practical applications, they can be set according to the specific circumstances. This application does not impose any limitations on these settings.
[0058] The input terminal of the first switching circuit 5 is connected to the first conduction signal generation circuit 2. Therefore, after the first conduction signal is generated, the first switching circuit 5 can be turned on by the first conduction signal. Furthermore, the output terminal of the first switching circuit 5 is connected to the first heating circuit 6. Therefore, after the first switching circuit 5 is turned on, the first heating circuit 6 can operate, that is, the first heating circuit 6 can generate heat.
[0059] The input terminal of the second switching circuit 7 is connected to the second conduction signal generation circuit 3. Therefore, after the second conduction signal is generated, the second switching circuit 7 can be turned on by the second conduction signal. Furthermore, the output terminal of the second switching circuit 7 is connected to the second heating circuit 8. Therefore, after the second switching circuit 7 is turned on, the second heating circuit 8 can operate, that is, the second heating circuit 8 can generate heat.
[0060] The input terminals of the first switching circuit 5 and the second switching circuit 7 are both connected to the third conduction signal generation circuit 4. Therefore, after the third conduction signal generation circuit 4 generates the third conduction signal, both the first switching circuit 5 and the second switching circuit 7 can be turned on by the third conduction signal. Furthermore, the output terminal of the first switching circuit 5 is connected to the first heating circuit 6, and the output terminal of the second switching circuit 7 is connected to the second heating circuit 8. Thus, after the first switching circuit 5 and the second switching circuit 7 are simultaneously turned on, the first heating circuit 6 and the second heating circuit 8 can operate simultaneously, that is, the first heating circuit 6 and the second heating circuit 8 can generate heat simultaneously.
[0061] As described above, the heating power of the first heating circuit 6 and the second heating circuit 8 are different. Therefore, the heating power of the atomizing device is different in the three cases mentioned above: when only the first heating circuit 6 is working, when only the second heating circuit 8 is working, and when both the first heating circuit 6 and the second heating circuit 8 are working. Thus, the different heating requirements of the atomizing device can be met.
[0062] As an example, suppose the heating power corresponding to the first heating circuit 6 is low, and the heating power corresponding to the second heating circuit 8 is medium. Then, when only the first heating circuit 6 is operating, the heating power of the atomizing device is low; when only the second heating circuit 8 is operating, the heating power of the atomizing device is medium; when both the first heating circuit 6 and the second heating circuit 8 are operating, the heating power of the atomizing device is the sum of the heating power of the first heating circuit 6 and the heating power of the second heating circuit 8. For example, in this case, the heating power of the atomizing device is high.
[0063] It should be noted that the above description assumes that the heating power of the atomizing device can be low, medium, or high. Alternatively, in application, the heating power of the first heating circuit 6 and the second heating circuit 8 can be set according to actual conditions to change the heating power of the atomizing device. In other words, this application embodiment does not limit the heating power of the atomizing device, the heating power of the first heating circuit 6, or the heating power of the second heating circuit 8.
[0064] In some embodiments, the heating power of the heating unit can be changed by changing the duty cycle of the first switching circuit 5 and / or the second switching circuit 7, thereby changing the heating power of the atomizing device.
[0065] In some embodiments, please refer to Figure 3 The sensing module includes a variable capacitor C1. The capacitance of the variable capacitor C1 can change according to the area of the nozzle 1 being contacted, thereby outputting electrical signals of different magnitudes.
[0066] Additionally, in some embodiments, please refer to Figure 4 The first switching circuit 5 includes a MOSFET Q1 and a restraining resistor R1, and the first heating circuit 6 includes a first heating element 61. The gate G of the MOSFET Q1 is connected to one end of the first conduction signal generation circuit 2, the third conduction signal generation circuit 4, and the restraining resistor R1, respectively. The source S of the MOSFET Q1 is connected to the power supply and the other end of the restraining resistor R1, respectively. The drain D of the MOSFET Q1 is connected to one end of the first heating element 61, and the other end of the first heating element 61 is connected to the working ground.
[0067] The gate G of MOSFET Q1 is connected to the first conduction signal generation circuit 2. Therefore, after the first conduction signal generation circuit 2 generates the first conduction signal, the gate G of MOSFET Q1 will receive the first conduction signal, thereby turning on MOSFET Q1. The drain D of MOSFET Q1 is connected to the first heating element 61. Therefore, after MOSFET Q1 is turned on, the first heating element 61 will also generate heat.
[0068] Since MOSFET Q1 is an electronic component, its source S needs to be connected to the power supply to provide power to MOSFET Q1.
[0069] The restraint resistor R1 is connected between the gate G and the source S of the MOSFET Q1. When there is no drive signal, such as the absence of the first or third conduction signal, the restraint resistor R1 can provide a discharge path for the gate charge, pulling the gate voltage down to the source potential and preventing the MOSFET from being accidentally turned on due to charge accumulation or external interference. When the gate G receives a drive signal, such as the first or third conduction signal, the restraint resistor R1 can release the gate charge, thereby improving the switching speed.
[0070] In some embodiments, please refer to Figure 4The second switching circuit 7 includes a MOSFET Q2 and a restraining resistor R2, and the second heating circuit 8 includes a second heating element 81. The gate of the MOSFET Q1 is connected to one end of the second conduction signal generation circuit 3, the third conduction signal generation circuit 4, and the restraining resistor R2, respectively. The source of the MOSFET Q2 is connected to the power supply and the other end of the restraining resistor R2, respectively. The drain of the MOSFET Q2 is connected to one end of the second heating element 81. The other end of the second heating element 81 is connected to the working ground.
[0071] The gate G of MOSFET Q2 is connected to the second conduction signal generation circuit 3. Therefore, after the second conduction signal generation circuit 3 generates the second conduction signal, the gate G of MOSFET Q2 will receive the second conduction signal, thereby turning on MOSFET Q2. The drain D of MOSFET Q2 is connected to the second heating element 81. Therefore, after MOSFET Q2 is turned on, the second heating element 81 will also generate heat.
[0072] Since MOSFET Q2 is an electronic component, its source S needs to be connected to the power supply to provide power to MOSFET Q2.
[0073] The restraint resistor R2 is connected between the gate G and the source S of the MOSFET Q2. When there is no drive signal, such as no second or third conduction signal, the restraint resistor R2 can provide a discharge path for the gate charge, pulling the gate voltage down to the source potential and preventing the MOSFET from being accidentally turned on due to charge accumulation or external interference. When the gate G receives a drive signal, such as the second or third conduction signal, the restraint resistor R2 can release the gate charge and improve the switching speed.
[0074] This application embodiment provides an atomizing device with a sensing module inside the nozzle. This module outputs a corresponding electrical signal based on the contact area of the nozzle. A first, second, and third conduction signal generation circuit generate corresponding conduction signals based on the range of the electrical signal, thereby turning the first and second switching circuits on or off. This, in turn, turns the first and second heating circuits on or off. The first and second heating circuits have different heating powers, thus meeting the different heating requirements of the atomizing device. In summary, this application embodiment provides an atomizing device that operates with a corresponding heating power based on the contact area of the nozzle, i.e., automatically adjusting the heating power through lip contact, simplifying the power adjustment process of the atomizing device.
[0075] Figure 5 This is a schematic diagram of the structure of an atomizing device provided in an embodiment of this application. Please refer to it. Figure 5The atomizing device includes a mouthpiece 1, a heating unit 2, a first switching circuit 3, and a second switching circuit 4. The heating unit 2 includes at least a first heating circuit 21 and a second heating circuit 22, with different heating powers. The output terminal of the first switching circuit 3 is connected to the first heating circuit 21, and the first heating circuit 21 can be activated when the first switching circuit 3 is turned on. The output terminal of the second switching circuit 4 is connected to the second heating circuit 22, and the second heating circuit 22 can be activated when the second switching circuit 4 is turned on. A sensing module 11 is provided inside the mouthpiece 1. The sensing module 11 is used to output a corresponding electrical signal according to the contact area of the mouthpiece 1. The magnitude of the electrical signal is positively correlated with the contact area of the mouthpiece 1. The electrical signal is used to select one or both of the first switching circuit 3 and the second switching circuit 4 to be turned on based on its different range.
[0076] To meet the different heating requirements of the atomizing device, the heating unit 2 includes at least a first heating circuit 21 and a second heating circuit 22, and the heating powers of the first heating circuit 21 and the second heating circuit 22 are different. As an example, suppose the heating power of the first heating circuit 21 is low and the heating power of the second heating circuit 22 is medium; then, when only the first heating circuit 21 is heating, the heating power of the atomizing device is low; when only the second heating circuit 22 is heating, the heating power of the atomizing device is medium; when the first heating circuit 21 and the second heating circuit 22 are heating simultaneously, the heating power of the atomizing device is the sum of the low heating power and the medium heating power, such that the heating power of the atomizing device is high.
[0077] It should be noted that the above description assumes that the heating unit 2 includes a first heating circuit 21 and a second heating circuit 22. Alternatively, in application, the heating unit 2 may include more heating units 2 to meet the heating requirements of the atomizing device. For example, the heating unit 2 may also include a third heating circuit, and the heating power of the third heating circuit is different from that of the first heating circuit 21 and the second heating circuit 22. For instance, the heating power of the first heating circuit 21 is low, the heating power of the second heating circuit 22 is medium, and the heating power of the third heating circuit is high. Therefore, when only the first heating circuit 21 is heating, the heating power of the atomizing device is low; when only the second heating circuit 22 is heating, the heating power is medium; and when only the third heating circuit is heating, the heating power is high. If higher heating power is required, any two of the three circuits can be used. In other words, the embodiments of this application do not limit the number of heating circuits in the heating unit 2.
[0078] In some embodiments, the output terminal of the first switching circuit 3 is connected to the first heating circuit 21, so that when the first switching circuit 3 is turned on, the first heating circuit 21 can generate heat; the output terminal of the second switching circuit 4 is connected to the second heating circuit 22, so that when the second switching circuit 4 is turned on, the second heating circuit 22 can generate heat.
[0079] When the atomizing device is used, the mouthpiece 1 will come into contact with the user's lips to perform inhalation. When the mouthpiece 1 is in contact, its built-in sensing module 11 will sense the contact area and output a corresponding electrical signal. The magnitude of the output electrical signal is positively correlated with the contact area of the mouthpiece 1. That is, the larger the contact area of the mouthpiece 1, the larger the electrical signal output by the sensing module 11, and the smaller the contact area of the mouthpiece 1, the smaller the electrical signal output by the sensing module 11.
[0080] As an example, when the area of the nozzle 1 in contact accounts for 30% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is X; when the area of the nozzle 1 in contact accounts for 60% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is Y; when the area of the nozzle 1 in contact accounts for 100% of the area of the nozzle 1, the magnitude of the electrical signal output by the sensing module 11 is Z; where Z is greater than Y and greater than X.
[0081] In some embodiments, to facilitate the sensing module 11 in outputting a corresponding electrical signal based on the contact area of the suction nozzle 1, and to facilitate suction by the user, please refer to... Figure 2 The nozzle 1 may include: a first segment 12, the diameter of which is a first diameter; and a second segment 13, which is perpendicularly connected to the first segment 12, the diameter of which is a second diameter, which is larger than the first diameter.
[0082] Additionally, in some embodiments, please refer to Figure 2 The nozzle 1 may also include a third section 14, which is located between the first section 12 and the second section 13, and the diameter of the third section 14 gradually increases from the first section 12 to the second section 13.
[0083] It should be noted that the above description assumes a positive correlation between the magnitude of the electrical signal and the area of the suction nozzle 1 in contact. Alternatively, in application, the magnitude of the electrical signal can also be negatively correlated with the area of the suction nozzle 1 in contact; that is, the larger the area of the suction nozzle 1 in contact, the smaller the electrical signal output by the sensing module 11, and vice versa. In other words, this embodiment does not limit the correlation between the magnitude of the electrical signal and the area of the suction nozzle 1 in contact.
[0084] Continuing the description above, the electrical signal is used to select whether one or both of the first switching circuit 3 and the second switching circuit 4 are turned on, depending on the range in which the electrical signal is within. That is, if the electrical signal is within different ranges, the following situations may occur: the first switching circuit 3 is turned on and the second switching circuit 4 is turned off; the second switching circuit 4 is turned on and the first switching circuit 3 is turned off; or both the first switching circuit 3 and the second switching circuit 4 are turned on.
[0085] In some embodiments, please refer to Figure 6 The sensing module includes a variable capacitor C1. The capacitance of the variable capacitor C1 can change according to the area of the nozzle 1 being contacted, thereby outputting electrical signals of different magnitudes.
[0086] In some embodiments, please refer to Figure 7 The atomizing device may also include comparator U1 and comparator U2. From Figure 7 As can be seen, the non-inverting input of comparator U1 is connected to the sensing module, the inverting input of comparator U1 is connected to the first reference voltage, and the output of comparator U1 is connected to the first switching circuit 3. Similarly, the non-inverting input of comparator U2 is also connected to the sensing module, the inverting input of comparator U2 is connected to the second reference voltage, and the output of comparator U2 is connected to the input of the second switching circuit 4. Furthermore, the first reference voltage and the second reference voltage are different. Therefore, the range of the electrical signal can be determined using comparators U1 and U2, and one or both of the first switching circuit 3 and the second switching circuit 4 can be selected to be turned on.
[0087] As an example, suppose the voltage corresponding to the electrical signal is X. Comparator U1 is set to output a high level when the voltage at the non-inverting input is greater than the voltage at the inverting input (i.e., the voltage corresponding to the electrical signal is greater than the first reference voltage), and output a low level otherwise. Comparator U2 is set to output a high level when the voltage at the non-inverting input is less than the voltage at the inverting input (i.e., the voltage corresponding to the electrical signal is less than the second reference voltage), and output a low level otherwise. Both the first switching circuit 3 and the second switching circuit 4 are turned on when a high level is received, and the first reference voltage is less than the second reference voltage. If X is less than the first reference voltage, then comparator U1 outputs a low level, comparator U2 outputs a high level, and the first switching circuit 3 is off, while the second switching circuit 4 is on. If X is greater than the first reference voltage and less than the second reference voltage, then both comparator U1 and comparator U2 output a high level, and both the first switching circuit 3 and the second switching circuit 4 are on. If X is greater than the second reference voltage, then comparator U1 outputs a high level, comparator U2 outputs a low level, and both the first switching circuit 3 and the second switching circuit 4 are on. Therefore, it is possible to select one or both of the first switching circuit 3 and the second switching circuit 4 to be turned on based on the electrical signal.
[0088] It should be noted that the above description uses comparator U1 and comparator U2 to select one or both of the first switching circuit 3 and the second switching circuit 4 to be turned on. Of course, in application, more comparators, logic gates, comparators and logic gates, or other methods can be used to select one or both of the first switching circuit 3 and the second switching circuit 4 to be turned on based on the magnitude of the electrical signal. This application does not limit this.
[0089] In some embodiments, please refer to Figure 8 The first switching circuit 3 includes a MOSFET Q1 and a restraining resistor R1, and the first heating circuit 21 includes a first heating element 211. The gate of the MOSFET Q1 is connected to the output terminal of the comparator U1 and one end of the restraining resistor R1, the source of the MOSFET Q1 is connected to the power supply and the other end of the restraining resistor R1, and the drain of the MOSFET Q1 is connected to one end of the first heating element 211. The other end of the first heating element 211 is connected to the working ground.
[0090] The gate G of MOSFET Q1 is connected to the output of comparator U1. Therefore, when comparator U1 outputs a high level, MOSFET Q1 will be turned on, and when comparator U1 outputs a low level, MOSFET Q2 will not be turned on. Furthermore, the drain D of MOSFET Q1 is connected to the first heating element 211. Therefore, after MOSFET Q1 is turned on, the first heating element 211 will also generate heat.
[0091] Since MOSFET Q1 is an electronic component, its source S needs to be connected to the power supply to provide power to MOSFET Q1.
[0092] The restraint resistor R1 is connected between the gate G and the source S of the MOSFET Q1. When there is no drive signal, the restraint resistor R1 can provide a discharge path for the gate charge, pull the gate voltage down to the source potential, and prevent the MOSFET from being turned on unexpectedly due to charge accumulation or external interference. When the gate G receives a drive signal, the gate charge can be released through the restraint resistor R1, thereby improving the switching speed.
[0093] In some embodiments, please refer to Figure 8 The second switching circuit 4 includes a MOSFET Q2 and a restraining resistor R2. The second heating circuit 22 includes a second heating element 221. The gate of the MOSFET Q1 is connected to the output terminal of the comparator U2 and one end of the restraining resistor 2. The source of the MOSFET Q2 is connected to the power supply and the other end of the restraining resistor R2. The drain of the MOSFET Q2 is connected to one end of the second heating element 221. The other end of the second heating element 221 is connected to the working ground.
[0094] The gate G of MOSFET Q2 is connected to the output of comparator U2. Therefore, MOSFET Q2 will be turned on when comparator U2 outputs a high level and will not be turned on when comparator U2 outputs a low level. The drain D of MOSFET Q2 is connected to the second heating element 221. Therefore, the second heating element 221 will also generate heat after MOSFET Q2 is turned on.
[0095] Since MOSFET Q2 is an electronic component, its source S needs to be connected to the power supply to provide power to MOSFET Q2.
[0096] The restraint resistor R2 is connected between the gate G and the source S of the MOSFET Q2. When there is no drive signal, the restraint resistor R2 can provide a discharge path for the gate charge, pull the gate voltage down to the source potential, and prevent the MOSFET from being turned on unexpectedly due to charge accumulation or external interference. When the gate G receives a drive signal, the gate charge can be released through the restraint resistor R2, thereby improving the switching speed.
[0097] This application embodiment provides an atomizing device with a sensing module inside the nozzle. This module outputs a corresponding electrical signal based on the contact area of the nozzle. This signal, depending on its range, is used to select one or both of a first and second switching circuit to be activated, thereby activating one or both of a first and second heating circuit. The first and second heating circuits have different heating powers, thus meeting the different heating requirements of the atomizing device. In summary, this application embodiment provides an atomizing device that operates with a corresponding heating power based on the contact area of the nozzle; that is, it automatically adjusts the heating power through lip contact, simplifying the power adjustment process of the atomizing device.
