[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] The utility model provides an electromagnetic solenoid atomizer oil quantity control structure, which has a simple structure and does not generate noise caused by motor rotation during operation, meeting the needs of users. At the same time, the oil quantity is automatically calculated to open and close the valve during use, eliminating the need for tedious manual operations.

[0025] like Figures 1 to 5 As shown, the utility model is an electromagnetic solenoid atomizer oil quantity control structure, including an electromagnet 1, a sealing piston assembly 2, an oil storage tank 3, a working oil tank 4, a heating chamber 5, and a main board 7. The main board 7 is provided with an MCU module, an electromagnetic solenoid control module, the heating chamber 5 is connected to the working oil tank 4, and the oil storage tank and the working oil tank 4 are connected through an oil filling hole 6. The upper end of the sealing piston assembly 2 cooperates with the oil filling hole 6, and the lower end of the sealing piston assembly 2 is connected to the electromagnet 1. The MCU module controls the power on and off of the electromagnet 1 through the electromagnetic solenoid control module. When the electromagnet 1 is powered off, the sealing piston assembly 2 is pulled down to close the oil filling hole 6. When the electromagnet 1 is powered on, a magnetic force is generated to lift the sealing piston assembly 2 upward to open the oil filling hole 6.

[0026] This electromagnetic solenoid atomizer oil quantity control structure includes an atomization circuit control system, a charging system, and an electromagnetic solenoid control system. Its operating principle and characteristics also include an additional electromagnetic solenoid control module and a driving electromagnetic solenoid circuit at one end of the atomizer oil storage tank 3.

[0027] The electromagnet 1 and the sealing piston assembly 2 together form the valve for the oil filling hole 6. When the atomizer is in operation, when the oil filling time is reached, the electromagnetic solenoid control module can automatically open the electromagnetic valve. After each start-up and opening of the valve, the electromagnetic solenoid control module closes the electromagnetic valve 1 after reaching a fixed oil filling amount. By alternating the operation of the electromagnetic solenoid, the electromagnetic valve 1 can be closed and opened, automatically opening and closing the oil storage tank 3, thereby injecting the oil in the oil storage tank 3 into the atomizer, continuously filling the atomizer with oil. Different operating modes can also be achieved through the electromagnetic valve 1 to meet the needs of different users.

[0028] like Figure 5As shown, the MCU module includes a chip U2, and the electromagnet solenoid control module includes a MOS transistor Q2, an electromagnet solenoid M1, a voltage-stabilizing diode D1, a resistor R13, and a resistor R15. The electromagnet solenoid M1 is connected to the electromagnet 1, the source of the MOS transistor Q2 is connected to one end of the electromagnet solenoid M1 and the cathode of the voltage-stabilizing diode D1, the other end of the electromagnet solenoid M1 and the anode of the voltage-stabilizing diode D1 are grounded, the drain of the MOS transistor Q2 is connected to one end of the resistor R13 and the BAT+ port respectively, the gate of the MOS transistor Q2 is connected to the other end of the resistor R13 and one end of the resistor R15 respectively, and the other end of the resistor R15 is connected to the PWM2 pin of the chip U2.

[0029] Working principle of electromagnet solenoid:

[0030] When PWM2 receives the low level signal from chip U2, MOS tube Q2 is turned on, that is, electromagnet solenoid M1 is energized, and electromagnet 1 generates magnetic force to lift the sealing piston assembly 2 upward, thereby opening the oil filling hole 6.

[0031] When PWM2 receives a high level signal from chip U2, MOS tube Q2 is disconnected, i.e., electromagnet solenoid M1 is powered off. The magnetic force of electromagnet 1 disappears, and the sealing piston assembly 2 is pulled downward by the elastic force of spring 15, so that the oil filling hole 6 is closed.

[0032] Add the voltage regulator diode D1 to prevent the spike voltage generated by the solenoid switch of the electromagnet.

[0033] like Figure 6 As shown, the electromagnetic solenoid atomizer oil quantity control structure also includes a heating wire 10, the main board 7 is also provided with a heating wire control module, the MCU module includes a chip U2, the heating wire control module includes a MOS tube Q1, a resistor R9, a resistor R10, and a resistor R12. The source of the MOS tube Q1 is respectively connected to one end of the resistor R10 and one end of the heating wire 10, the other end of the heating wire 10 is grounded, the other end of the resistor R10 is connected to the VDCDC_READ pin of the chip U2, the drain of the MOS tube Q1 is respectively connected to one end of the resistor R9 and the BAT+ port, the gate of the MOS tube Q1 is respectively connected to the other end of the resistor R9 and one end of the resistor R12, and the other end of the resistor R12 is connected to the PWM1 pin of the chip U2. Figure 5 F1 represents the heating wire 10.

[0034] like Figure 4 As shown, the electromagnetic solenoid atomizer oil quantity control structure further includes a microphone 9, and the MCU module further includes a resistor R16. One end of the microphone 9 is connected to one end of the resistor R16, the other end of the microphone 9 is grounded, and the other end of the resistor R16 is connected to the MIC Out pin of the chip U2. Figure 3 MIC1 indicates microphone 9

[0035] The electromagnet solenoid atomizer oil quantity control structure further comprises a battery 8 , wherein the positive electrode of the battery 8 is connected to the BAT+ port, and the negative electrode of the battery 8 is grounded. Figure 5 BAT2 represents the battery 8. The battery 8 supplies power to the heating wire 10, the coil of the electromagnet, and the MCU module through the BAT+ port.

[0036] like Figure 7 As shown, the mainboard 7 also includes a charging module, the MCU module includes a chip U2, the charging module includes a chip U1 and a charging interface 21, the 4th pin of the chip U1 is connected to the charging interface 21, the 5th pin of the chip U1 is connected to the 5V READ pin of the chip U2, the 1st pin of the chip U1 is connected to the C CHECK pin of the chip U2, and the 3rd pin of the chip U1 is connected to the BAT+ port. Figure 6 J1 in FIG. 2 represents the charging interface 21 .

[0037] like Figure 8 As shown, the mainboard 7 also includes a gyroscope acceleration sensor module, the MCU module includes a chip U2, and the gyroscope acceleration sensor module includes a chip U3. Pins 12, 2, 5, and 6 of the chip U3 are respectively connected to the SCL pin, SDA pin, INT1 pin, and INT2 pin of the chip U2.

[0038] A gyroscope detection device chip U3 is added. Chip U3 communicates with the MCU via SCL, SDA, INT1, and INT2. When chip U3 detects that the e-cigarette is tilted too far, it disconnects MOS tube Q2, lowers sealing plug 14, and closes oil filling hole 6. This is because when the electronic atomizer is lying down or the mouthpiece is facing downward, opening oil filling hole 6 prevents the e-liquid from entering the oil reservoir 11. Only when the electronic atomizer is placed upright or tilted at a shallow angle (for example, the set angle is less than 45 degrees) can the atomized oil be injected into the oil reservoir 11.

[0039] The sealing piston assembly includes a sealing plug 14, a connecting rod 13, and a spring 15. The sealing plug 14 fits over the oil filling hole 6. One end of the connecting rod 13 passes through the oil filling hole 6 and connects to the sealing plug 14. The connecting rod 13 is provided with a retaining ring 16. The spring 15 is sleeved on the connecting rod 13, with its ends connected between the retaining ring 16 and the oil filling hole 6. When the oil filling hole 6 is closed, the sealing plug 14 is in close contact with the oil filling hole 6. When the oil filling hole 6 is opened, the sealing plug 14 is separated from the oil filling hole 6.

[0040] Electromagnet 1 is equipped with a push rod 12, which is driven by the electromagnet 1 to extend and retract. Push rod 12 is connected to the other end of connecting rod 13. A solenoid is wound inside electromagnet 1. When energized, the magnetic force generated by electromagnet 1 opposes the elastic force of spring 15, allowing push rod 12 to overcome the elastic force of spring 15 and lift connecting rod 13.

[0041] Through the structure of the sealing piston assembly 2 and the electromagnet 1, when the electromagnet 1 is powered off and loses its magnetic force, the spring 15 will drive the connecting rod 13 to move downward under the action of the reset elastic force, and the sealing plug 14 will be simultaneously pulled down to block the oil filling hole 6, thereby closing the oil storage tank 3 from filling the working oil tank 4 with oil; when the electromagnet 1 is powered on and generates magnetic force, the magnetic force is greater than the reset elastic force of the spring 15, thereby pushing the connecting rod 13 to move upward and lifting the sealing plug 14 from the oil filling hole 6. At this time, the oil storage tank 3 and the working oil tank 4 are connected, and the oil filling state is started.

[0042] The electromagnetic solenoid atomizer oil quantity control structure also includes a heating wire 10 and an oil reservoir 11. The heating wire 10 and the oil reservoir 11 are assembled in the heating chamber 5. The oil reservoir 11 wraps around the heating wire 10 and contacts the working oil tank 4. The oil reservoir 11 is used to absorb the atomized oil in the working oil tank 4. When the heating wire 10 is energized, the oil in the oil reservoir 11 is heated to achieve the atomization effect.

[0043] The electromagnetic solenoid atomizer oil volume control structure also includes a suction nozzle 17, the airway of which is connected to the heating chamber 5 via a central air pipe 19. When air is inhaled at the suction nozzle 17, the air pressure in the airway changes. The microphone 9 senses the pressure change and transmits a signal to the main board 7, thereby triggering the main board 7's heating wire 10 control module to energize and heat the heating wire 10, thereby heating and atomizing the oil in the oil-storing cotton 11.

[0044] The electromagnetic solenoid atomizer oil control mechanism also includes an outer shell 20, which protects the internal structure and decoration. The interior of the outer shell 20 comprises an oil reservoir housing 22 and a heating bracket 23, which are sealed together. The oil reservoir 3 is located within the oil reservoir housing 22, while the working oil reservoir 4 and the heating chamber 5 are located within the heating bracket 23. An oil filling port 6 is provided on the heating bracket 23, connecting the oil reservoir 2 and the working oil reservoir 4. A sealed bottom cover 24 is connected to the bottom of the heating bracket 23, and the microphone 9 is assembled within the sealed bottom cover 24.

[0045] like Figures 1 to 3 As shown, there are two ways to connect the suction nozzle 17 and the central air pipe 20. The first is to connect a seal 18 to the top of the oil storage tank bracket 3 to seal the oil storage tank 3. The suction nozzle 17 is a separate structural component, and the central air pipe 20 is set on the heating bracket 23 and connected to the heating chamber 5. At the same time, a suction hole is provided in the seal 18 to connect the suction nozzle 17 and the central air pipe 20. The second is to form the suction nozzle 17, the central air pipe 20 and the oil tank shell 22 as a whole. The suction nozzle 17 and the central air pipe 20 are connected internally. The bottom of the central air pipe 20 is connected to the heating bracket 23 through the seal 18 and connected to the heating chamber 5.

[0046] The main working modes of the electromagnetic solenoid atomizer oil quantity control structure are:

[0047] (1) Oil filling hole 6 closed state: When the heating wire 10 is working, the heating wire 10 works when the first pin of the chip U2 of the MCU module receives the trigger signal of the microphone 9, and controls the opening of the MOS tube Q1 through PWM1 to supply power to the heating wire 10; the VDCDC_READ of the chip U2 is used to detect the output of Q1. The PWM2 pin of the circuit chip U2 outputs a high level, which makes the MOS tube Q2 in the off state. At this time, the electromagnet solenoid M1 is not energized, that is, there is no magnetic force. The sealing piston assembly 2 is reset under the elastic force of the spring 15, and the oil filling hole 6 is closed.

[0048] (2) The oil filling hole 6 is open: When the heating wire 10 stops working, the trigger signal of the microphone 9 stops and Q1 is turned off. The MCU module performs detection. When it is detected that the working time of the heating wire 10 reaches the set time, which is set by the software of the MCU module, the chip U2 of the MCU module outputs a low level through the pin PWM2, and the MOS tube Q2 is in the on state. At this time, the electromagnet solenoid M1 is energized, and the electromagnet 1 generates an upward magnetic force. Under the action of the magnetic force, the sealing piston assembly 2 is lifted up, and the oil filling hole 6 is opened, so that the oil in the oil storage tank 3 flows to the working oil tank 4, providing oil to the oil storage cotton 11; when the oil filling time reaches the set value, the pin PWM2 of the chip U2 provides a high level again, and the MOS tube Q2 is in the off state. At this time, the magnetic force of the electromagnet 1 disappears, and the electromagnet 1 has no magnetic force. The sealing piston assembly 2 is reset under the elastic force of the spring 15, and the oil filling hole 6 is closed again.

[0049] (3) In order to achieve a better control effect, the working frequency and power-on time of the electromagnetic solenoid are related to the power of the heating wire 10 and the oil storage capacity of the oil storage cotton 11. Therefore, it is necessary to reasonably adjust the working frequency and power-on time of the electromagnetic solenoid according to different designs and in combination with actual applications, so as to ensure that the heating wire 10 does not burn dry and that the oil storage capacity of the oil storage cotton 11 is sufficient, and there will be no oil leakage due to excessive oil filling.

[0050] This solution integrates the electromagnetic solenoid with the main body of the atomizer product. This allows the electromagnetic solenoid to open and close smoothly during use, resulting in a better overall product experience and minimal noise, which does not affect the user. Furthermore, the use of the electromagnetic valve 1 can lock the oil inside the sealed oil storage tank 3, avoiding many oil leaks caused by environmental factors.

[0051] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
