Technical Field
[0001] This application belongs to the field of atomizing equipment, and specifically relates to an atomizing device. Background Technology
[0002] Typically, an atomizing device contains an atomizing tube and a heating element, with the heating element located within the atomizing tube.

However, in related technologies, it is difficult to determine the remaining amount of atomizing medium. Once the amount of atomizing medium in the atomizing tube decreases or even if it is completely used up, continued heating by the heating element may cause the atomizing device to dry-burn, resulting in the liquid-conducting medium in the atomizing core being burned and generating harmful gases.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0026] like Figure 1 and Figure 2 As shown, the atomizing device includes: an atomizing tube 10 forming a hollow channel; a liquid-conducting medium 30 disposed within the hollow channel for conducting the atomizing medium; a heating element 20 disposed on the inner wall of the liquid-conducting medium 30 for heating the atomizing medium; a resistance detection circuit 50 electrically connected to the atomizing tube 10 for detecting the resistance of the liquid-conducting medium 30 to obtain a feedback signal; and a control element 40 electrically connected to the resistance detection circuit 50 for obtaining the resistance of the liquid-conducting medium 30 based on the feedback signal; wherein the resistance is configured to characterize the remaining amount of the atomizing medium. The control element 40 is configured to perform at least a first operation based on the feedback signal.
[0027] In one embodiment, reference Figure 2 The first operation can be that the control element 40 controls the power supply 60 to stop the voltage output, that is, the second switching element 90 is in the off state; the first operation can also be that the control element 40 controls the atomizing device to output an alarm signal, such as a screen display reminder, an alarm sound, etc. The first operation can also be some complex combined operation, for example, if the user inhales again within 5 minutes after the alarm sound reminder, and the feedback signal still indicates that the remaining atomizing medium is insufficient, the power supply 60 is then controlled to stop the voltage output.
[0028] In this embodiment, since the atomizing tube 10 has a hollow channel, a liquid guiding medium 30 can be placed in the hollow channel to conduct the atomizing medium into the atomizing tube 10. The heating element 20 can be placed on the inner wall of the liquid guiding medium 30 to heat the atomizing medium in the atomizing tube 10, so that the atomizing medium can form an aerosol, which is convenient for users to use the atomizing device.
[0029] In addition, the resistance detection circuit 50 is electrically connected to the atomizing tube 10, so that the resistance of the liquid guiding medium 30 can be detected by the resistance detection circuit 50 to obtain a feedback signal. The control element 40 is also electrically connected to the resistance detection circuit 50, so that the control element 40 can receive the feedback signal from the resistance detection circuit 50 and obtain the resistance of the liquid guiding medium 30 based on the feedback signal. The resistance is configured to characterize the remaining amount of the atomizing medium, so that the remaining amount of the atomizing medium in the atomizing tube 10 can be determined by determining the resistance of the liquid guiding medium 30.
[0030] That is, in this embodiment of the application, by setting a resistance detection circuit 50 and a control element 40, the resistance detection circuit 50 detects the resistance of the liquid guiding medium 30 in the atomizing tube 10 and obtains a feedback signal. The control element 40 obtains the feedback signal and determines the resistance of the liquid guiding medium 30 according to the feedback signal, thereby determining the remaining amount of atomizing medium in the atomizing tube 10. This allows for a more accurate determination of the remaining amount of atomizing medium in the atomizing tube 10, avoiding the problem of the atomizing medium in the atomizing tube 10 decreasing or even being completely used up, causing the heating element 20 to continue heating and leading to the atomizing device burning dry. This also avoids the problem of the liquid guiding medium 30 of the atomizing device burning dry and forming harmful gases.
[0031] It should be noted that, in this embodiment, the heating element 20 is located in the hollow channel of the atomizing tube 10, the liquid guiding medium 30 covers the heating element 20, and the liquid guiding medium 30 is in contact with the channel wall of the hollow channel of the atomizing tube 10, that is, the liquid guiding medium 30 is in contact with the inner wall of the atomizing tube 10. Thus, when the liquid guiding medium 30 is transferred to the atomizing medium, the atomizing medium can contact the inner wall of the atomizing tube 10, and the atomizing medium can contact the heating element 20, so that the heating element 20 can heat the atomizing medium.
[0032] In addition, the atomizing medium has a certain degree of conductivity. When the heat-conducting medium and the heating element 20 are installed in the atomizing tube 10, the atomizing medium comes into contact with the inner wall of the atomizing tube 10 and the heating element 20, respectively. Thus, a resistance can be formed between the heating element 20 and the atomizing tube 10. When the atomizing medium is reduced, the resistance between the heating element 20 and the atomizing tube 10 increases. Therefore, the remaining amount of the atomizing medium can be determined based on the resistance between the heating element 20 and the atomizing tube 10.
[0033] In addition, in this embodiment, a resistance threshold can be set. Once the control element 40 receives the feedback signal from the resistance detection circuit 50, the control element 40 determines the resistance between the heating element 20 and the atomizing tube 10. If the resistance between the heating element 20 and the atomizing tube 10 is greater than or equal to the resistance threshold, it indicates that the remaining amount of atomizing medium in the atomizing tube 10 is low. The control element 40 can then control the heating element 20 to stop heating, thus preventing the atomizing device from potentially burning out. The control element 40 is electrically connected to the heating element 20, and the control element 40 can control the heating element 20 to either heat up or stop heating.
[0034] In addition, in this embodiment, the liquid guiding medium 30 can be liquid guiding cotton. Of course, the liquid guiding medium 30 can also be other components that can transmit to the atomizing medium. This embodiment does not limit the specific components.
[0035] Additionally, in some embodiments, such as Figure 2 As shown, the atomizing device is equipped with a power supply 60; the resistance detection circuit 50 includes: a resistor assembly 51, the first end of which is connected to the power supply 60, and the second end of which is electrically connected to the atomizing tube 10; a control element 40 is electrically connected to the first end and the second end of the resistor assembly 51 respectively; wherein, the control element 40 is used to collect the voltage between the first end and the second end of the resistor assembly 51 to determine the resistance between the atomizing tube 10 and the heating element 20.
[0036] Since the first end of resistor assembly 51 is connected to power supply 60, the second end of resistor assembly 51 is electrically connected to atomizing tube 10, and one pin of heating element 20 is grounded, once power supply 60 supplies power to resistor assembly 51, current can flow to resistor assembly 51, then to atomizing tube 10, through the atomizing medium, and to heating element 20. One pin of heating element 20 is grounded, allowing the current to form a path; that is, the current from power supply 60 flows out of power supply 60, through various components, and finally to ground. Since control element 40 is electrically connected to both the first and second ends of resistor assembly 51, the voltage between the first and second ends of resistor assembly 51 can be measured by control element 40 to determine the resistance between atomizing tube 10 and heating element 20. In other words, by setting resistor assembly 51 and power supply 60, and grounding one pin of heating element 20, control element 40 can easily determine the resistance between atomizing tube 10 and heating element 20.
[0037] It should be noted that the control element 40 can determine the resistance between the atomizing tube 10 and the heating element 20 by collecting the voltage between the first and second terminals of the resistor assembly 51.
[0038] R = (ADC1 - ADC2) / R1 * ADC2
[0039] Wherein, ADC1 represents the first terminal voltage of resistor component 51, ADC2 represents the second terminal voltage of resistor component 51, R1 represents the resistance value of resistor component 51, and R represents the resistance value between atomizing tube 10 and heating element 20.
[0040] Additionally, in some embodiments, such as Figure 2 As shown, the resistor assembly 51 includes at least one detection resistor 511; the first end of the detection resistor 511 is connected to the power supply 60, and the second end of the detection resistor 511 is electrically connected to the atomizing tube 10; the control element 40 is electrically connected to the first end and the second end of the detection resistor 511 respectively; or, the resistor assembly 51 includes at least two detection resistors 511, and the at least two detection resistors 511 are connected in series to form a resistor group; the first end of the resistor group is electrically connected to the power supply 60, and the second end of the resistor group is electrically connected to the atomizing tube 10; the control element 40 is electrically connected to the first end and the second end of the resistor group respectively.
[0041] When the resistor assembly 51 includes at least one sensing resistor 511, the first end of the sensing resistor 511 can be connected to the power supply 60, and the second end of the sensing resistor 511 can be electrically connected to the atomizing tube 10. The control element 40 is electrically connected to both the first and second ends of the sensing resistor 511. Therefore, the control element 40 can determine the resistance between the atomizing tube 10 and the heating element 20 based on the resistance value of the sensing resistor 511, the voltage at the first end of the sensing resistor 511, and the voltage at the second end of the sensing resistor 511. When there is only one detection resistor 511, R1 represents the resistance value of a single detection resistor 511, ADC1 represents the voltage at the first terminal of the single detection resistor 511, and ADC2 represents the voltage at the second terminal of the single detection resistor 511. If there are multiple detection resistors 511, R1 represents the sum of the resistance values of the multiple detection resistors 511, ADC1 represents the voltage at the first terminal of the detection resistor 511 connected to the power supply 60, and ADC2 represents the voltage at the second terminal of the detection resistor 511 connected to the atomizing tube 10.
[0042] When the resistor assembly 51 includes at least two detection resistors 511, the at least two detection resistors 511 are connected in series to form a resistor group. The first end of the resistor group is electrically connected to the power supply 60, and the second end of the resistor group is electrically connected to the atomizing tube 10. The control element 40 is electrically connected to the first end and the second end of the resistor group respectively. Thus, the control element 40 can determine the resistance between the atomizing tube 10 and the heating element 20 based on the resistance value of the resistor group, the voltage at the first end of the resistor group, and the voltage at the second end of the resistor group. At this time, R1 represents the sum of the resistance values of at least two detection resistors 511 in the resistor group, ADC1 represents the voltage at the first end of the resistor group, and ADC2 represents the voltage at the second end of the resistor group.
[0043] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the atomizing device also includes a first switching element 70; the first end of the first switching element 70 is electrically connected to the resistor assembly 51, the second end of the first switching element 70 is electrically connected to the power supply 60, and the control end of the first switching element 70 is electrically connected to the control element 40; wherein, the control element 40 is configured to control the first end and the second end of the first switching element 70 to be turned on or off.
[0044] Since the first end of the first switching element 70 is electrically connected to the resistor assembly 51, the second end of the first switching element 70 is electrically connected to the power supply 60, and the control end of the first switching element 70 is electrically connected to the control element 40, the control element 40 can control the first switching element 70 to make it in a conducting state, that is, the first end and the second end of the first switching element 70 are connected. The current from the power supply 60 can then flow through the first switching element 70 to the resistor assembly 51, and then to the atomizing tube 10. This allows the control element 40 to collect the voltage across the resistor assembly 51, and thus determine the remaining amount of atomizing medium in the atomizing tube 10. Alternatively, the control element 40 can control the first switching element 70 to make it in a disconnected state, that is, the first end and the second end of the first switching element 70 are disconnected. As a result, the current from the power supply 60 cannot flow to the resistor assembly 51, and thus the control element 40 will not determine the remaining amount of atomizing medium in the atomizing tube 10. That is, by setting the first switching element 70, when it is necessary to determine the remaining amount of atomizing medium in the atomizing tube 10, the first end of the first switching element 70 can be controlled to be connected to the second end by the control element 40, and when it is not necessary to determine the remaining amount of atomizing medium in the atomizing tube 10, the first end of the first switching element 70 can be controlled to be disconnected by the control element 40.
[0045] It should be noted that the first switching element 70 can be a MOSFET, which can be an N-type MOSFET or a P-type MOSFET.
[0046] Additionally, in some embodiments, such as Figure 2 As shown, the atomizing device also includes a first resistor 80; the first end of the first resistor 80 is electrically connected to the first end of the first switching element 70, and the second end of the first resistor 80 is electrically connected to the control end of the first switching element 70.
[0047] Since the first end of the first resistor 80 is electrically connected to the first end of the first switching element 70, and the second end of the first resistor 80 is electrically connected to the control end of the first switching element 70, while the first end of the first switching element 70 is electrically connected to the power supply 60, it is equivalent to the first resistor 80 being connected to the power supply 60. Therefore, the current from the power supply 60 can be transmitted to the first resistor 80, and then through the first resistor 80 to the control end of the first switching element 70, allowing the control end of the first switching element 70 to receive a voltage signal. This ensures that when the control element 40 does not control the first switching element 70, the first end of the first switching element 70 is disconnected from the second end; or, after the control element 40 controls the first switching element 70 to conduct, the first switching element 70 is reset, i.e., the first end of the first switching element 70 is disconnected from the second end. In other words, by setting the first resistor 80, the first switching element 70 is kept in an open state when the control element 40 does not control it, and the first switching element 70 is easily reset after the control element 40 controls it.
[0048] Additionally, in some embodiments, such as Figure 1 or Figure 2 As shown, the atomizing device also includes a second switching element 90; the first end of the second switching element 90 is electrically connected to one end of the heating element 20, the second end of the second switching element 90 is electrically connected to the power supply 60, and the control end of the second switching element 90 is electrically connected to the control element 40; wherein, the control element 40 is configured to control the first end and the second end of the second switching element 90 to be turned on or off.
[0049] Since the first end of the second switching element 90 is electrically connected to one end of the heating element 20, the second end of the second switching element 90 is electrically connected to the power supply 60, and the control end of the second switching element 90 is electrically connected to the control element 40, the control element 40 can control the second switching element 90 so that the second switching element 90 is in a conducting state, that is, the first end and the second end of the second switching element 90 are connected. The current from the power supply 60 can then flow through the second switching element 90 to the heating element 20, causing the heating element 20 to heat up and heat the atomizing medium in the atomizing tube 10, thereby atomizing the atomizing medium in the atomizing tube 10.
[0050] Furthermore, the above-mentioned configuration allows the control element 40 to control the second switching element 90, causing the second switching element 90 to be in an open state, i.e., the first and second terminals of the second switching element 90 are disconnected. This prevents current from the power supply 60 from flowing to the heating element 20, thus stopping the heating element 20 from heating. In other words, by providing the second switching element 90, it is convenient to control whether the heating element 20 is heating.
[0051] Understandably, the heating element 20 includes at least one first pin and at least one second pin. The first terminal of the second switching element 90 is electrically connected to the first pin of the heating element 20, and the second pin of the heating element 20 is configured to be grounded. For example, the first pin is configured as the positive terminal of the heating element 20, and the second pin is configured as the negative terminal of the heating element 20. The remaining amount of atomizing medium is determined by detecting the resistance between the first pin and the sidewall of the atomizing tube 10.
[0052] It should be noted that the second switching element 90 can be a MOSFET, which can be an N-type MOSFET or a P-type MOSFET.
[0053] It should also be noted that, such as Figure 2 As shown, both the PWM signal and the IO signal refer to the signals emitted by the control element 40, thereby controlling the first switching element 70 and the second switching element 90.
[0054] Additionally, in some embodiments, such as Figure 2 As shown, the atomizing device also includes a second resistor 120; the first end of the second resistor 120 is electrically connected to the first end of the second switching element 90, and the second end of the second resistor 120 is electrically connected to the control end of the second switching element 90.
[0055] Since the first end of the second resistor 120 is electrically connected to the first end of the second switching element 90, and the second end of the second resistor 120 is electrically connected to the control terminal of the second switching element 90, while the second end of the second switching element 90 is electrically connected to the power supply 60, it is equivalent to the second resistor 120 being connected to the power supply 60. Therefore, the current from the power supply 60 can be transmitted to the second resistor 120, and then through the second resistor 120 to the control terminal of the second switching element 90, causing the control terminal of the second switching element 90 to receive a voltage level signal.
[0056] When the control element 40 does not control the second switching element 90, it ensures that the first and second terminals of the second switching element 90 are disconnected; or, after the control element 40 controls the first and second terminals of the second switching element 90 to conduct, the second switching element 90 is reset, i.e., the first and second terminals of the second switching element 90 are disconnected. In other words, by setting the second resistor 120, it is possible to ensure that the second switching element 90 remains in an open state when the control element 40 does not control it, and to facilitate the reset of the second switching element 90 after the control element 40 controls it.
[0057] Additionally, in some embodiments, such as Figure 1 As shown, the atomizing device also includes a control button 110; the control button 110 is electrically connected to the control element 40; wherein, the control button 110 is configured to send a command to the control element 40 when the control button 110 is pressed, to instruct the control element 40 to control the first terminal of the first switching element 70 to be connected to the second terminal, and to control the first terminal of the second switching element 90 to be disconnected from the second terminal.
[0058] Since the control button 110 is electrically connected to the control element 40, when the user presses the control button 110 during the use of the atomizing device, the control button 110 will send a command to the control element 40, instructing the control element 40 to control the first terminal of the first switching element 70 to be connected to the second terminal, and to control the first terminal of the second switching element 90 to be disconnected from the second terminal.
[0059] At this time, the current from the power supply 60 can be transmitted to the resistor assembly 51 through the first switching element 70, allowing the control element 40 to obtain the voltage across the opposite ends of the resistor assembly 51. The control element 40 can then determine the remaining amount of atomizing medium in the atomizing tube 10. However, the current from the power supply 60 will not be transmitted to the heating element 20 through the second switching element 90, and the heating element 20 will stop heating. In other words, by pressing the control button 110, the user can cause the control element 40 to determine the remaining amount of atomizing medium in the atomizing tube 10, and when determining the remaining amount, the heating element 20's heating will prevent it from cutting off atomization in the atomizing tube 10.
[0060] In other words, by setting the control button 110, the user can decide when to determine the remaining amount of atomizing medium in the atomizing tube 10.
[0061] In addition, in this embodiment of the application, when the first switching element 70 is off and the second switching element 90 is on, the control element 40 is configured to collect the voltage between the first and second terminals of the resistor assembly 51; and / or, when the control element 40 determines that the resistance between the atomizing tube 10 and the heating element 20 is greater than or equal to a preset resistance threshold, the control element 40 controls the second switching element 90 to remain off.
[0062] Specifically, once the first and second ends of the first switching element 70 are connected and the first and second ends of the second switching element 90 are disconnected, the current from the power supply 60 can be transmitted to the resistor assembly 51 through the first switching element 70, so that the resistor assembly 51 has voltage, and the control element 40 can collect the voltage between the two opposite ends of the resistor assembly 51.
[0063] In addition, once the control element 40 determines that the resistance between the atomizing tube 10 and the heating element 20 is greater than or equal to the preset resistance threshold, it indicates that the remaining amount of atomizing medium in the atomizing tube 10 is small. Therefore, the control element 40 controls the second switching element 90 to remain in the off state to prevent the current from the power supply 60 from being transmitted to the heating element 20, thereby preventing the heating element 20 from heating the small amount of atomizing medium in the atomizing tube 10. This effectively avoids the problem of dry burning of the atomizing device when there is a small amount of atomizing medium in the atomizing device.
[0064] Additionally, in some embodiments, such as Figure 1 As shown, the atomizing device also includes an indicator light 100, which is electrically connected to the control element 40; wherein the indicator light 100 is configured to emit light when the resistance between the atomizing tube 10 and the heating element 20 is greater than or equal to a preset resistance threshold.
[0065] Since the indicator light 100 is electrically connected to the control element 40, after the control element 40 determines the resistance value between the atomizing tube 10 and the heating element 20, it can control the indicator light 100 according to this resistance value, thus alerting the user. Specifically, when the control element 40 determines that the resistance value between the atomizing tube 10 and the heating element 20 is greater than or equal to a preset resistance threshold, it indicates that the remaining amount of atomizing medium in the atomizing tube 10 is low. Therefore, the control element 40 will control the indicator light 100 to illuminate, alerting the user that the atomizing medium in the atomizing device is low. In other words, by setting the indicator light 100, the user can easily know the remaining amount of atomizing medium in the atomizing device.
[0066] In some embodiments, the atomizing device also includes a housing; the atomizing tube 10, the control element 40, and the resistance detection circuit 50 are all located within the housing, and the indicator light 100 is mounted on the housing. This design protects the atomizing tube 10, the control element 40, and the resistance detection circuit 50, and the housing also facilitates gripping and use of the atomizing device. Furthermore, the indicator light 100 is mounted on the housing, making it easily visible to the user when illuminated, thus allowing the user to easily determine the remaining amount of atomizing medium in the atomizing device.
