[0021] Please refer to Figure 1 , which is a structural block diagram of an atomization electrical energy output control device in an embodiment. The atomization electrical energy output control device includes a power supply 10, a first atomization control circuit 20, a second atomization control circuit 30, a first heating element 40, and a second heating element 50. The power supply 10 is used to provide electrical energy. The first atomization control circuit 20 is connected between the power supply 10 and the first heating element 40. The first atomization control circuit 20 includes a MOS switch tube. When the MOS switch tube is turned on, the electrical energy output by the power supply 10 is output to the first heating element 40 for the first heating element 40 to output atomization heat energy. The second atomization control circuit 30 is connected between the power supply 10 and the second heating element 50. The second atomization control circuit 30 includes a MOS switch tube. When the MOS switch tube is turned on, the electrical energy output by the power supply 10 is output to the second heating element 50 for the second heating element 50 to output atomization heat energy. Among them, the first heating element 40 and the second heating element 50 output atomization heat energy alternately.
[0022] In some embodiments, the power output from the power supply 10 to the first heating element 40 is different from the power output to the second heating element 50, and the duty cycle of the MOS switch tube of the first atomization control circuit 20 is different from the duty cycle of the MOS switch tube of the second atomization control circuit 30. In some embodiments, the power output from the power supply 10 to the first heating element 40 is the same as the power output to the second heating element 50, and the duty cycle of the MOS switch tube of the first atomization control circuit 20 is the same as the duty cycle of the MOS switch tube of the second atomization control circuit 30.
[0023] In some embodiments, when the power supply 10 alternately supplies power to the first heating element 40 and the second heating element 50, the alternating time interval is less than or equal to the switching cycle value of the MOS switch tube of the first atomization control circuit 20 or the second atomization control circuit 30. In some embodiments, when the power supply 10 supplies power to the first heating element 40 and the second heating element 50 in a staggered manner, the staggering time is less than or equal to the switching cycle value of the MOS switch tube of the first atomization control circuit 20 or the second atomization control circuit 30.
[0024] In some embodiments, each atomization cycle during the atomization process of the electronic atomizer includes a first atomization time period, a second atomization time period, and a third atomization time period. Among them, during the first atomization time period, the power supply of the electronic atomizer supplies power to the first heating element alone, so that the first heating element outputs atomization heat energy; during the second atomization time period, the power supply of the electronic atomizer supplies power to the first heating element and the second heating element simultaneously, so that the first heating element and the second heating element jointly output atomization heat energy; during the third atomization time period, the power supply of the electronic atomizer supplies power to the second heating element alone, so that the second heating element outputs atomization heat energy. The durations of the first atomization time period, the second atomization time period, and the third atomization time period are respectively a preset first duration, a second duration, and a third duration, and the second duration is less than or equal to the first duration, or the second duration is less than or equal to the third duration. In one embodiment, the first duration, the second duration, and the third duration are respectively less than or equal to the switching cycle value of the MOS switch tube of the first atomization control circuit and / or the second atomization control circuit.
[0025] In some embodiments of the present application, an electronic atomizer is also disclosed, including the atomization electric energy output control device as described above.
[0026] Please refer to Figure 2 For a schematic flow chart of an atomization electric energy output control method in an embodiment. In some embodiments of the present application, an atomization electric energy output control method is also disclosed, which is applied to the electronic atomizer as described above. The atomization electric energy output control method includes: Step 101, obtain an atomization start electrical signal.
[0027] Receive the atomization start electrical signal sent by the start sensor (gas sensor) of the electronic atomizer.
[0028] Step 102, send a switch control signal to the atomization control circuit.
[0029] Send a first PWM pulse width signal and a second PWM pulse width signal to the first atomization control circuit 20 and the second atomization control circuit 30 respectively.
[0030] Step 103, the two heating elements work in a staggered manner.
[0031] The power supply 10 supplies power to the first heating element 40 and the second heating element 50 respectively through the first atomization control circuit 20 and the second atomization control circuit 30 including MOS switch tubes. When the MOS switch tube of the first atomization control circuit 20 is turned on, the first heating element 40 is supplied with power, and when the MOS switch tube of the second atomization control circuit 30 is turned on, the second heating element 50 is supplied with power. The first atomization control circuit 20 responds to the first PWM pulse width signal to output the power supply 10 to the first heating element 40, and the second atomization control circuit 30 responds to the second PWM pulse width signal to output the power supply 10 to the second heating element 50. During the atomization process of the electronic atomizer, the power supply 10 of the electronic atomizer alternately supplies power to the first heating element 40 and the second heating element 50, so that the first heating element 40 and the second heating element 50 alternately output atomized heat energy.
[0032] In some embodiments, the first heating element 40 and the second heating element 50 are two separate heating elements, both of which are connected to the power source 10 and share a common ground. When the first heating element 40 and the second heating element 50 work alternately in an atomization cycle, the output is staggered to reduce the discharge loss of the power source 10, thereby increasing the discharge time of the power source 10. The power source 10 is an energy storage battery.
[0033] In some embodiments, the switching frequency (the number of times the MOS switch tube of the first atomization control circuit 20 is turned on in a preset unit time) of the MOS switch tube of the second atomization control circuit 30 is the same. In some embodiments, the power output by the power supply 10 to the first heating element 40 is different from the power output to the second heating element 50. In some embodiments, the switching duty cycle of the MOS switch tube of the first atomization control circuit 20 is different from the switching duty cycle of the MOS switch tube of the second atomization control circuit 30. In some embodiments, the conduction of the MOS switch tubes of the first atomization control circuit 20 and the second atomization control circuit 30 is controlled by the MCU controller through the PWM pulse width signal respectively, and the conduction time / duty cycle of the MOS switch tube is the time / duty cycle of the PWM pulse width signal correspondingly issued by the MCU controller. In some embodiments, the MCU controller controls the conduction and disconnection of the MOS switch tube by adjusting the duty cycle of the PWM pulse width signal issued to the MOS switch tubes of the first atomization control circuit 20 and the second atomization control circuit 30 respectively, and finally controls the working power of the first heating element 40 and the second heating element 50 respectively.
[0034] In some embodiments, when the power supply 10 of the electronic atomizer alternately supplies power to the first heating element 40 and the second heating element 50, the alternating time interval is less than or equal to the switching period value of the MOS switch tube of the first atomization control circuit 20 or the second atomization control circuit 30. In some embodiments, when the power supply 10 of the electronic atomizer supplies power to the first heating element 40 and the second heating element 50 alternately, the alternating time is less than or equal to the switching period value of the MOS switch tube of the first atomization control circuit 20 or the second atomization control circuit 30.
[0035] Step 104, stop atomization.
[0036] When the atomization start electrical signal disappears, stop the output of the first PWM pulse width signal and the second PWM pulse width signal, and then stop the electrical energy output of the power supply to stop the atomization process.
[0037] To facilitate understanding of the application mode of the atomization electrical energy output control method in the embodiments of the present application, the following is described through specific embodiments, including: 1) Alternating working mode.
[0038] Please refer to Figure 3 , which is a schematic diagram of the timing of obtaining electrical energy of the heating element in an embodiment. Taking a dual-heating-element electronic atomizer as an example, when obtaining the atomization start electrical signal (high level), the first heating element and the second heating element work alternately. Whether the first heating element and the second heating element obtain electrical energy is determined by the on and off time points of the MOS switch tubes of the first atomization control circuit and the second atomization control circuit. The two-way switch signals (the first PWM pulse width signal and the second PWM pulse width signal) are asynchronous switches, that is, within one cycle at the same time point, when the MOS switch tube of the first atomization control circuit is turned on and the MOS switch tube of the second atomization control circuit is turned off, the first heating element obtains electrical energy and heats up. When the MOS switch tube of the second atomization control circuit is turned on and the MOS switch tube of the first atomization control circuit is turned off, the second heating element obtains electrical energy and heats up. According to the above working mode, the asynchronous operation of the two-way heating elements within the same cycle is realized, the duration of the discharge peak value of the power supply is prolonged, the discharge is more balanced, the discharge capacity of the power supply for a longer time is realized, and thus the requirement for the number of atomization times of the atomizer under the discharge cycle of the power supply is ensured.
[0039] 2) Cross working mode.
[0040] Please refer to Figure 4, which is a schematic diagram of the timing for obtaining electrical energy of the heating element in another embodiment. Taking a dual-heating-element electronic atomizer as an example, when an atomization start electrical signal (high level) is obtained, the first heating element and the second heating element work alternately. Whether the first heating element and the second heating element obtain electrical energy is determined by the on and off time points of the MOS switching transistors of the first atomization control circuit and the second atomization control circuit. It is set that the total power of a single atomization of the atomizer is P = 20W, and the heat energy is output by the dual-channel heating element. The switching frequencies of the first PWM pulse width signal and the second PWM pulse width signal are 2K (T = 500uS). The effective voltage value of the electrical energy obtained by the first heating element is 3.4442V, and the duty cycle of the electrical energy output is 87.5% (the effective output time in a single cycle is 437.5uS); the effective value of the electrical energy obtained by the second heating element is 2.9458V, and the duty cycle of the electrical energy output is 66.5% (the effective output time in a single cycle is 332.5uS). As Figure 4 shown, during the atomization process of the electronic atomizer, each atomization cycle includes three atomization time periods: The first atomization time period, in which the first heating element works alone, and the duration t1 = 167.5uS.
[0041] The second atomization time period, in which the first heating element and the second heating element work together, and the duration t2 = 270uS (staggered time).
[0042] The third atomization time period, in which the second heating element works alone, and the duration t3 = 62.5uS.
[0043] In each atomization cycle, the switching stagger time of the MOS switching transistors of the first atomization control circuit and the second atomization control circuit is t = 230uS. In this way, the maximum discharge duration of the power supply in one atomization cycle is only 270uS. If synchronous output is adopted, the maximum discharge duration of the power supply in one cycle is 332.5uS. Obviously, the maximum discharge duration of the power supply in a single cycle is reduced, providing an effective basis for extending the discharge time of the power supply.
[0044] The atomization electrical energy output control device disclosed in the embodiment of the present application includes a power supply, a first atomization control circuit, a second atomization control circuit, a first heating element, and a second heating element. The first and second atomization control circuits are respectively connected between the first and second heating elements. The first and second atomization control circuits respectively include MOS switching transistors. When the MOS switching transistors are turned on, the electrical energy output by the power supply is output to the first and second heating elements for the first and second heating elements to output atomization heat energy. Among them, the first and second heating elements alternately output atomization heat energy. Since the two heating elements work alternately, the peak discharge duration of the power supply is longer and the discharge is more balanced, so as to ensure the discharge ability of the power supply for a longer time. Furthermore, on the premise of ensuring the constant power supply capacity, the atomization times of the electronic atomizer are increased, and the charge and discharge times of the power supply are reduced, thus extending the service life.
[0045] The above uses specific examples to elaborate on this application, which is only for helping to understand this application and is not intended to limit this application. For those skilled in the technical field to which this application pertains, based on the idea of this application, several simple deductions, deformations or substitutions can also be made.
