[0022] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, an adjustment circuit for atomizer control is characterized by,

[0023] The adjustment circuit S1 includes: a first resistor R1, a MOSFET M1, and a pulse width modulator (PWM). The power input terminal of the adjustment circuit S1 is connected to both the source of the MOSFET and one end of the first resistor R1. The drain of the MOSFET serves as the atomizer connection terminal F+, which is connected to the built-in resistor and voltage output terminal VOUT of the atomizer. The other end of the first resistor R1 is connected to both the gate of the MOSFET and the signal output terminal of the PWM. The PWM signal output terminal VOUT outputs electrical signals of different frequency wavelengths to the gate of the MOSFET to control the adjustment circuit S1.

[0024] Specifically, the adjustment circuit S1 is equipped with a pulse width modulator (PWM), a MOSFET, a diode D2, a first resistor R1, and an atomizer (not shown in the figure) that are electrically connected during use. The atomizer connection terminal F+ of the adjustment circuit S1 is connected to the built-in resistor of the atomizer. At this time, the PWM in the adjustment circuit detects the resistance value of the built-in resistor connected to the atomizer connection terminal F+ in real time. Based on this resistance value, it finds a suitable atomization control frequency or atomization control frequency curve parameter in the parameter table as a preset value. The atomizer uses this frequency to control the output at the moment of startup, so that the current through the atomizer connection terminal F+ reaches a certain peak value, slowing down the current flow rate through the atomizer connection terminal F+. This further reduces or increases the frequency of the sharp sound produced by the atomizer to a frequency beyond that that can be perceived by the human ear. In a specific embodiment, the atomizer with the adjustment circuit installed will not produce a sharp sound, improving the user experience and the overall smoothness of the atomizer's use.

[0025] Specifically, the pulse width modulator (PWM) in the adjustment circuit S1 dynamically and in real time detects the resistance of the atomizer. When the change exceeds a certain range, the PWM finds a suitable frequency or atomization control frequency curve parameter in the parameter table and adjusts the frequency of the PWM output signal accordingly. This setting method is circuit feedback adjustment, which prevents the large current passing through the atomizer connection terminal F+ during the use of the atomizer from producing a sharp sound that affects the overall use of the atomizer.

[0026] Furthermore, the atomizer has a fixed resistance of 0.1Ω to 3Ω, and the wavelength range of the fixed current flowing into the atomizer connection varies to a certain extent. In one embodiment, the resistance curve of the built-in resistor connected to the atomizer connection and the atomization control frequency signal are as follows: Figure 2 As shown, at times t1, t2, and t3, the resistance value of the built-in resistor connected to the atomizer terminal F+ changes within a jump range. The atomization control frequency signal follows this change and adjusts dynamically to prevent the atomizer from producing a sharp sound, thus affecting the overall normal operation of the atomizer.

[0027] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, a diode D2 is connected in series between the source and drain of the MOS transistor M1. This diode D2 is a Zener diode.

[0028] Specifically, the diode D2 in the circuit is a Zener diode. The current flows from the power supply through the voltage of the Zener diode D2 to the parallel wire ports. During the transmission process, the voltage at each wire port is equal, ensuring that the total impedance of the parallel wire ports is reduced to a certain value and that other components are not damaged due to excessive current. This ensures the stability of the current flowing into the atomizer connection terminal F+ and the voltage output terminal, preventing the atomizer from making a sharp sound when releasing vapor due to excessive instantaneous current at the atomizer connection terminal through the adjustment circuit S1.

[0029] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, an adjustment circuit for atomizer control is characterized in that the MOS transistor is a field-effect enhancement type P-MOS transistor.

[0030] Specifically, the MOSFET M1 is a positive-channel metal-oxide-semiconductor (PSMOS). In this design, the MOSFET M1 in the adjustment circuit can achieve voltage control after assembly. The PMOS has high impedance, allowing current to flow through the MOSFET towards the atomizer output terminal with the same wavelength as the control signal. The drain of the PMOS is connected to the Zener diode D2, and multiple wire ports are connected in parallel. Current flows through these parallel wire ports to the atomizer connection terminal F+ and the voltage output terminal VOUT. This configuration ensures that the voltage from the power supply through the Zener diode is equal at each wire port, reducing the total impedance of the parallel wire ports and preventing damage to other components due to current loss. This guarantees the stability of the current flowing into the atomizer and the voltage output terminal.

[0031] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, an adjustment circuit for atomizer control is provided, wherein the resistance of the first resistor R1 is 2KΩ.

[0032] Specifically, the first resistor R1 is set to a resistance value of 2KΩ to limit the current flowing into the power supply, preventing excessive current from flowing into the pulse width modulator (PWM) and thus damaging the components in the adjustment circuit. This setting ensures that the wavelength of the frequency emitted by the PWM in the adjustment circuit is not affected by the large current of the power supply, thereby affecting the normal operation of the atomizer. It also ensures that the atomizer does not produce abnormal noises (sharp sounds and popping sounds) during use while releasing aerosol, thus ensuring the smooth operation of the atomizer.

[0033] Furthermore, the F+ terminal in the circuit diagram is the atomizer connection terminal, and this terminal is connected to a built-in resistor. This built-in resistor is located inside the atomizer, and its resistance ranges from 0.1Ω to 3Ω. When used in conjunction with the MOSFET and PWM (Pulse Width Modulator) in the adjustment circuit, it ensures smooth current input, improving the user experience. This further ensures that the atomizer smoothly produces aerosol when used, enhancing the overall smoothness of atomizer operation.

[0034] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, the adjustment circuit S1 further includes a second resistor R2. One end of the second resistor R2 is connected to the pulse width modulator PWM, and the other end of the second resistor R2 is connected to the other end of the first resistor R1 and the gate of the MOS transistor.

[0035] Specifically, the second resistor R2 is connected in series with the gate of the MOSFET. The setting of the second resistor R2 in the adjustment circuit enhances the overall protection of the circuit and prevents excessive current from the pulse width modulator from damaging the components in the adjustment circuit. In one embodiment, the resistance value of the second resistor R2 is 10Ω, and the second resistor R2 is a circuit protection resistor in the adjustment circuit. The resistance value of the second resistor R2 can be set according to the specific requirements of the manufacturer. This setting method improves the overall stability of the adjustment circuit S1 while ensuring the smooth operation of the adjustment circuit S1.

[0036] In the embodiments of the present invention, please refer to Figure 1 as well as Figure 2 As shown in the figure, the wavelength range of the electrical signal output by the pulse width modulator (PWM) is 20kHz to 100kHz.

[0037] Specifically, the wavelength range of the pulse width modulator (PWM) signal is 20kHz to 100kHz. This setting amplifies the current in the adjustment circuit S1 to a wavelength with the same frequency, allowing the same frequency signal to directly control the MOS transistor and limit the current at the atomizer connection terminal F+. This reduces or raises the generated sharp sound to a frequency beyond human hearing, making the sharp sound undetectable. This ensures a good user experience while maintaining the smoothness and stability of the atomizer's overall operation.

[0038] Furthermore, the built-in resistor of the atomizer has a fixed resistance value of 0.1Ω to 3Ω, and the wavelength range of the fixed current flowing into the built-in resistor of the atomizer varies to a certain extent. In one embodiment, the resistance curve of the built-in resistor at the atomizer connection end and the atomization control frequency signal are as follows: Figure 2As shown, at times t1, t2, and t3, the resistance value of the built-in resistor at the atomizer connection terminal changes in a jump interval when the electrical connection is made. At this time, the atomization control frequency signal is dynamically adjusted accordingly to prevent the atomizer from producing a sharp sound, thereby affecting the overall normal use of the atomizer.

[0039] In the embodiments of the present invention, please refer to Figure 1 As shown in the figure, the power supply voltage of the power input terminal VBAT is 3.2V to 4.15V, and the output voltage of the voltage output terminal VOUT is not greater than the voltage of the power input terminal VBAT.

[0040] Specifically, the power input terminal VBAT is a rechargeable battery built into the electronic atomizer in one embodiment. The rechargeable battery power supply voltage is set to a range of 3.2V to 4.15V. The voltage value after the power supply is connected to the adjustment circuit S1 is less than the voltage generated by the power supply itself. During the atomizer heating process, the current remains constant. However, when aerosol is generated, the actual voltage value generated by the change is less than the voltage at the power input terminal. A second resistor R2 is set between the MOSFET and the pulse width modulator (PWM), and R2 itself acts as a circuit protection resistor. This configuration further improves the overall voltage flow of the adjustment circuit, preventing excessive voltage input to the atomizer from causing popping or sharp sounds that affect the user experience, and further enhances the overall stability of the atomizer.

[0041] A specific control method for an adjustment circuit for atomizer control according to an embodiment of the present invention is as follows: The atomizer's resistance value is detected in real time. Based on this resistance value, a suitable atomization control frequency or atomization control frequency curve parameter is found in the parameter table and used as a preset value. This frequency is used to control the output at the moment the atomizer starts. During use, the atomizer's resistance value is dynamically detected in real time. When the change exceeds a certain range, a suitable frequency or atomization control frequency curve parameter is dynamically found in the parameter table, and the frequency of the output signal is adjusted accordingly. In one application case, the resistance curve of the built-in resistor at the atomizer connection terminal and the atomization control frequency signal are used as follows: Figure 2 As shown, at times t1, t2, and t3, the resistance value of the built-in resistor at the atomizer connection terminal changes in a jump range, and the atomization control frequency signal adjusts dynamically accordingly.

[0042] This invention discloses an adjustment circuit for atomizer control. The adjustment circuit includes a pulse width modulation circuit that outputs electrical signals of different frequency wavelengths. A MOSFET and a diode in the adjustment circuit respectively regulate and limit the current in the power supply. This configuration allows for smoother overall control of the current passing through the resistor at the atomizer connection terminal. The adjusted current, when used by the user in a device with the adjustment circuit installed, improves the smoothness of current control over the resistor at the atomizer connection terminal, further making the device smoother to use. It also stabilizes the current passing through the atomizer, preventing sharp noises from the atomizer during electrical connections.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
