When the electromagnet 52 solenoid is closed, the magnetic force of the electromagnet 52 disappears, and the top rod 53 is reset.

This design is a normally closed design, that is, under the action of the return spring 55, the oil injection hole 33 of the oil storage chamber 21 is always sealed.

[0051] The inner wall of the oil injection hole 33 near one end of the oil storage chamber 21 is provided with a sealing slope 36, and the lower end of the sealing plug 4 is provided with a sealing cone surface 42 matched with the sealing slope 36.

[0054] The shell further includes a shell 1, and the oil chamber upper shell 2, the atomization support 3, the main board 7, the battery 71, and the top rod electromagnetic valve 51 are all arranged in the shell 1. The shell 1 is used for aesthetic effect and is convenient for handheld use.

[0055] As shown in FIG. 5 and FIG. 6, as a form of the atomizer nozzle structure, the atomizer oil quantity control system further comprises a first sealing glue 82, a first nozzle 81, the atomizer support 3 is provided with a first central air pipe 37, the first sealing glue 82 is sealingly connected with the oil tank upper shell 2, the first sealing glue 82 is provided with a suction hole, the two ends of the first central air pipe 37 are respectively communicated with the atomization chamber 32 and the bottom of the suction hole, and the top of the suction hole is communicated with the first nozzle 81. The first sealing glue 82 not only plays a role of sealing the top of the oil storage tank 21, but also serves as a communication piece between the first central air pipe 37 and the first nozzle 81, so that the atomization chamber 32 and the first nozzle 81 are in air flow communication.

[0056] As shown in FIG. 7 and FIG. 8, as another form of the atomizer nozzle structure, the atomizer oil quantity control system further comprises a second sealing glue 83, the oil tank upper shell 2 is provided with a second nozzle 22 and a second central air pipe 23, the upper end of the second central air pipe 23 is communicated with the second nozzle 22, the atomizer support is provided with an atomization hole 38 communicated with the atomization chamber 32, the second sealing glue 83 is provided with a suction hole, and the two ends of the second sealing glue 83 are respectively connected with the atomization hole 38 and the second central air pipe 23.

[0057] The atomizer oil quantity control system further comprises a sealing bottom shell 9 and a microphone 91, the sealing bottom shell 9 is connected to the atomizer support 3 and seals the bottom of the atomization chamber 32, and the microphone 91 is connected to the sealing bottom shell 9. The sealing bottom shell 9 can seal the bottom of the atomization chamber 32, and the microphone 91 serves as an air hole for sensing the air flow entering the atomization chamber 32 when inhaling. The sealing bottom shell 9 can be further provided with an oil absorption cotton 92 for absorbing the atomized oil seeping from the atomization chamber 32 to prevent the atomized oil from leaking to the electronic components below.

[0058] Under normal circumstances, the sealing plug 4 is stretched under the elastic force of the reset spring 55, and the oil injection hole 33 is in a closed state, so as to ensure that the oil storage tank 21 does not leak oil during production, packaging, transportation and normal use. When the oil in the oil storage cotton 35 is consumed, the circuit recognizes and then opens the electromagnet 52. At this time, the top rod 53 of the electromagnet 52 pushes the top rod 53 against the elastic force of the reset spring 55, pushes away the sealing plug 4, and the oil in the oil storage tank 21 enters the working oil tank 31 from the oil injection hole 33 to replenish the oil for the oil storage cotton 35. After the oil replenishment is completed, the electromagnet 52 is powered off, the top rod 53 is reset, the sealing plug 4 is reset under the force of the reset spring 55, and the initial sealing state is restored. During the use cycle of the whole product, the above actions will be repeated for multiple times until all the oil in the oil storage tank 21 is consumed.

[0059] When the atomizer is working, the solenoid control circuit can automatically open the magnet body valve when the oil injection time is reached. After the valve is opened once, the fixed oil injection amount is reached, and the solenoid 52 valve is closed by the automatic control circuit. Through the turn-by-turn working mode of the solenoid of the solenoid 52, the solenoid 52 valve closing and opening mode, the opening and closing of the oil storage tank 21 are automatically controlled, so that the oil in the oil storage tank 21 is injected into the working oil tank 31, and the inside of the atomizing chamber 32 is continuously injected with oil. Different working modes can be achieved through the solenoid 52 valve to meet the needs of different groups of people.

[0060] As shown in FIGS. 9 and 10, the atomizer oil control system further includes a mainboard 7 arranged in the shell, the mainboard 7 is provided with an MCU module and a solenoid control module, the solenoid 52 is wound with a solenoid, the MCU module includes a chip U2, the solenoid control module of the solenoid 52 includes a MOS tube Q2, a voltage stabilizing diode D1, a resistor R13 and a resistor R15, the source of the MOS tube Q2 is connected with one end of the solenoid M1 and the negative electrode of the voltage stabilizing diode D1 respectively, the other end of the solenoid M1 and the positive electrode of the voltage stabilizing diode D1 are grounded, the drain of the MOS tube Q2 is connected with one end of the resistor R13 and the BAT+ port respectively, the gate of the MOS tube Q2 is connected with 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 with the PWM2 pin of the chip U2.

[0061] When the PWM2 receives the low level sent by the chip U2, the MOS tube Q2 is in a conductive state, that is, the solenoid M1 of the solenoid 52 is powered on, the solenoid 52 generates a magnetic force to lift the sealing plug 4 upward, so that the oil injection hole 33 is in an open state; when the PWM2 receives the high level sent by the chip U2, the MOS tube Q2 is in a disconnected state, that is, the solenoid M1 of the solenoid 52 is in a power-off state, the magnetic force of the solenoid 52 disappears, and the sealing plug 4 is pulled downward under the elastic force of the reset spring 55, so that the oil injection hole 33 is in a closed state. The voltage stabilizing diode D1 is added to prevent the solenoid switch of the solenoid 52 from generating a sharp voltage.

[0062] As shown in FIG. 9, the atomizer oil control system further includes a microphone 91 for sensing airflow, the microphone 91 is in communication with the atomizing chamber 32, and the MCU module further includes a resistor R16, the MIC Out pin of the chip U2, the resistor R16 and the microphone 91 are connected in series. When the user inhales through the mouthpiece, the microphone 91 will generate a change in air pressure, at which time the microphone 91 will sense a signal and output the signal to the chip U2 through the MIC Out pin. The chip U2 controls the power-on or power-off of the heating wire 34 according to the signal of the microphone 91. In FIG. 7, MIC1 represents the microphone 91.

[0063] The process of the MCU module controlling the opening or closing of the oil injection hole 33 is as follows:

[0064] a1. When the atomizer is not in use, the PWM2 pin of the chip U2 outputs a high level, the MOS tube Q2 is in the off state, the solenoid is powered off, the electromagnet 52 loses magnetic force, and the reset spring 55 drives the sealing plug 4 to move downward to close the oil injection hole 33;

[0065] a2. When the atomizer is in use, the microphone 91 triggers a signal, and the chip U2 starts to count the use time. When the use time set by the chip U2 is reached, the chip U2 outputs a low level through the PWM2 pin, the MOS tube Q2 is in the on state, the solenoid is powered on, the electromagnet 52 generates an upward magnetic force, and the sealing plug 4 is pushed open by the oil injection hole 33 through the top rod 53 and the connecting rod 54.

[0066] a3. When the sealing plug 4 is opened, the chip U2 starts to count the opening time. When the opening time set by the chip U2 is reached, the PWM2 pin of the chip U2 switches to output a high level, the MOS tube Q2 is in the off state, the solenoid is powered off, the electromagnet 52 loses magnetic force, and the reset spring 55 drives the sealing plug 4 to move downward to close the oil injection hole 33.

[0067] The electronic atomizer is internally designed with a mainboard 7. The MCU module in the mainboard 7 controls the user's smoking time through software algorithm, and calculates and counts the user's smoking time. After 50-80s of smoking, the circuit controls the electromagnetic valve to open the sealing plug 4, allowing the oil to enter the oil supplement warehouse for oil supplement. The electromagnetic valve is opened for 10-20s and then closed to stop oil supplement to prevent excessive oil supplement from leaking. 50-80s is the set time to open the oil injection hole 33. This time refers to the user inhaling through the mouthpiece, and the microphone 91 senses the change in air pressure to start counting. When 50-80s is reached, the heating wire 34 can just consume the oil in the oil storage cotton 35 and the working oil warehouse 31, so it is most suitable to open the sealing plug 4 to supplement the oil after reaching this time. According to the oil injection speed, the working oil warehouse 31 and the oil storage cotton 35 can be filled in about 10-20s, so the oil injection hole 33 is closed after reaching the time 。

[0068] As shown in FIG. 11, the mainboard 7 further comprises a heating wire control module, which comprises a MOS tube Q1, a resistor R9, a resistor R10 and a resistor R12.

The battery 71 supplies power to the heating wire 34, the solenoid 52 solenoid and the MCU module through the BAT+ port.

[0070] In order to achieve better control effect, the working frequency and the power-on time length of the solenoid 52 solenoid are related to the power of the heating wire 34, the oil storage capacity of the oil storage cotton 35 and the like, so it is necessary to adjust the working frequency and the time length of the solenoid 52 solenoid reasonably according to different designs and actual applications, so as to ensure that the heating wire 34 does not dry burning, and the oil storage capacity of the oil storage cotton 35 is sufficient, and the oil leakage phenomenon caused by excessive oil injection is avoided.

[0071] As shown in FIG. 12, the atomizer oil control system further comprises a charging interface 72, and the mainboard 7 further comprises a charging module, which comprises a chip U1. The 4th pin of the chip U1 is connected to the charging interface 72, 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. J1 in FIG. 10 represents the charging interface 72.

[0072] As shown in FIG. 13, the mainboard 7 further comprises a gyroscope acceleration sensor module, which comprises a chip U3. The 12th pin, the 2nd pin, the 5th pin and the 6th pin of the chip U3 are connected to the SCL pin, the SDA pin, the INT1 pin and the INT2 pin of the chip U2 respectively.

[0073] The process of controlling the opening or closing of the oil injection hole by the gyroscope acceleration sensor module is as follows:

[0074] b1. When the chip U3 detects that the inclination angle of the atomizer is greater than the set inclination angle, the chip U3 sends an inclination signal to the chip U2 through the SCL, SDA, INT1 and INT2 pins, the PWM2 pin of the chip U2 outputs a high level, the MOS tube Q2 is in an off state, the solenoid is powered off, the electromagnet 52 loses magnetic force, and the reset spring 55 drives the sealing plug 4 to move downward to close the oil injection hole 33.

[0075] b2. When the electronic atomizer is placed vertically or the inclination angle is less than the set inclination angle, the chip U3 stops sending signals to the chip U2.

[0076] The gyroscopic detection device chip U3 is added, the chip U3 is connected with the MCU for communication through the SCL, SDA, INT1 and INT2, when the chip U3 detects that the inclination angle of the electronic cigarette is too large, the MOS tube Q2 is disconnected, and the sealing plug 4 is lowered, that is, the oil injection hole 33 is closed. Because when the electronic atomizer is placed vertically or the mouthpiece is downward, the oil injection hole 33 is opened, and the tobacco tar cannot be injected into the oil storage cotton 35, only when the electronic atomizer is placed vertically or the inclination angle is not large (for example, the set angle is less than 45°), the oil injection hole 33 is opened, and the atomized oil can be injected into the oil storage cotton 35.

[0077] As shown in FIG. 14, the judgment process of the opening and closing of the oil injection hole 33 of the present application is as follows:

[0078] S1. The MCU module detects whether the heating wire 34 stops working through the VDCDC_READ of the chip U2, if the heating wire 34 is still in the working state, the process is ended, if the heating wire 34 has stopped working, S2 is executed;

[0079] S2. It is judged whether the time for opening the oil injection hole 33 is reached, if the time is not reached, the MOS tube Q2 is kept in the off state, and the process is ended, if the time is reached, S3 is executed;

[0080] S3. It is judged whether the inclination angle of the gyroscope is greater than the set value, if the set value is not reached, the MOS tube Q2 is kept in the off state, and the process is ended, if the set value is reached, the MOS tube Q2 is switched to the on state;

[0081] S4. It is judged whether the oil injection is completed, that is, whether the oil injection time reaches the set time, if the set time is not reached, S3 is executed, if the set time is reached, the MOS tube Q2 is disconnected, and the process is ended.

[0082] The specific circuit signal process in the above judgment process is as follows:

[0083] (1) Circuit state when oil filling hole 33 is closed: When heating wire 34 is working, heating wire 34 is working when pin 1 of chip U2 of MCU module receives the trigger signal of microphone 91MIC1, and controls the opening of MOS transistor Q1 through PWM1 to supply power to heating wire 34. VDCDC_READ of chip U2 is used to detect the output of MOS transistor Q1. The solenoid controller system outputs a high level through the PWM2 pin of circuit chip U2, and MOS transistor Q2 is in the off state. At this time, solenoid M1 is not energized, that is, electromagnet 52 has no magnetic force, and sealing plug 4 is in contact with oil filling hole 33 under the elastic force of reset spring 55, and oil filling hole 33 is in the closed state.

[0084] (2) Circuit state when oil filling hole 33 is open: When the heating wire 34 stops working, the microphone 91MIC1 trigger signal stops, thus turning off MOS transistor Q1. The MCU module performs detection. When it detects that the working time of the heating wire 34 has reached 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 pin PWM2, and MOS transistor Q2 is in the conducting state. At this time, solenoid M1 is energized, and electromagnet 52 generates an upward magnetic force. Under the action of the magnetic force, the top rod, connecting rod 54, and sealing plug 4 are lifted upward together, and oil filling hole 33 is opened, so that the oil in oil reservoir 21 flows to working oil reservoir 31, providing oil to oil storage cotton 35. When the oil filling time reaches the set value, pin PWM2 of chip U2 provides a high level again, MOS transistor Q2 is in the off state, electromagnet 52 has no magnetic force, and sealing plug 4 returns oil filling hole 33 to the closed state under the elastic force of return spring 55.

[0085] This invention integrates the electromagnet solenoid with the main body of the atomizing product. During use, the solenoid valve's opening and closing is smooth and gentle, resulting in better overall performance and minimal noise, minimizing user disturbance. Furthermore, the use of a solenoid valve effectively locks the oil within the sealed oil reservoir 21, preventing leaks caused by environmental factors. By controlling the oil inlet with the solenoid valve solenoid, the amount of oil dispensed can be precisely and periodically controlled, significantly improving performance and providing a superior user experience. It also reduces waste from insufficient oil filling, minimizing environmental pollution.

[0086] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
