Technical Field
[0001] The utility model relates to the technical field of electronic devices, in particular to a light-emitting electronic atomization device. Background Art
[0002] For the display in human-computer interaction of existing electronic atomization devices (such as electronic cigarettes), digital tubes, LCDs, OLEDs, and flexible screens are mostly used. The display effect of digital tubes is limited by the implementation principle (the light-emitting beads arranged on the PCB emit light through the film paper with printed patterns on the surface of the digital tube to form a light-emitting pattern), with strong granularity and uneven light emission; LCDs, OLEDs, and flexible screens have higher costs, and digital tubes, LCDs, and OLEDs cannot be bent, which limits the product structure. Compared with the above display methods, EL cold cathode fluorescent lamps have the advantages of soft and uniform light sources, low cost, bendability, simple manufacturing process, and high finished product yield. However, electronic cigarettes are powered by battery cells to meet the requirements of product volume (ensuring portability) and keeping the circuit structure simple (without adding an AC-DC circuit, low cost). The power supply is direct current and the voltage is much lower than the driving voltage of the EL cold cathode fluorescent lamp. Therefore, the existing technology cannot meet the application requirements of EL cold cathode fluorescent lamps in electronic cigarette products. Content of the Utility Model

The filter unit outputs the filtered and stabilized alternating current. The sampling feedback unit samples the output voltage of the transformer unit and then outputs it to the logic control unit. The logic control unit judges the output voltage of the sampling feedback unit and adjusts the control signal to regulate the output voltage. The display effect of the cold light sheet is controlled by the second electronic switch unit.
[0007] Further, the inverter unit is made of at least two MOS transistors or at least one triode (based on an inverter full-bridge circuit or a single-tube self-excited circuit). The inverter unit modulates the input voltage into an AC signal with a frequency of (0.6~9) Khz. The transformer unit uses a transformer or a buck-boost chip. The AC voltage with the preset voltage value is (60~150) V.
[0008] Further, a digital tube is also connected to the control board. The digital tube is connected to the logic control unit. The logic control unit controls the DC power output by the battery cell to be transmitted to the digital tube for lighting, which is used to display the status information of the electronic atomization device.
[0009] Further, the housing is composed of an upper cover and an outer shell. The top of the upper cover has a mouthpiece. The outer shell is arranged below the upper cover and encloses a cavity with the upper cover. The cold light sheet is arranged in the cavity and closely adheres to the inner wall of the outer shell.
[0010] Further, an upper silica gel is connected between the upper cover and the oil storage chamber, and a condensation cotton is arranged between the upper silica gel and the upper cover.
[0011] Further, it also includes a main bracket and a sub-bracket arranged in the housing. A lower silica gel is sleeved on the top of the main bracket.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-3As shown in the figure, a light-emitting electronic atomization device according to an embodiment of the present invention includes a housing, which is composed of an upper cover 1 and an outer shell 14. The top of the upper cover 1 has a mouthpiece. The outer shell 14 is disposed below the upper cover 1 and encloses a cavity with the upper cover 1. An oil storage chamber 4 is provided in the housing. An atomization core 6 is provided in the oil storage chamber 4. The atomization core 6 has a heating element. A storage cotton 5 is provided between the atomization core 6 and the oil storage chamber 4. An upper silica gel 3 is connected between the upper cover 1 and the oil storage chamber 4. A condensation cotton 2 is provided between the upper silica gel 3 and the upper cover 1. One end of the atomization core 6 is connected to a control board 11. One end of the control board 11 is connected to a battery cell 9. A digital tube 16 is also connected to the control board 11. A cold light sheet 13 connected to the control board 11 is further provided in the outer shell 14. The cold light sheet 13 is closely attached to the inner wall of the outer shell 14.
[0023] Furthermore, it further includes a main bracket 8 and a sub-bracket 10 provided in the housing. A lower silica gel 7 is sleeved on the top of the main bracket 8. The oil storage chamber 4 is sleeved on the lower silica gel 7. The atomization core 6 passes through the lower silica gel 7 and is fixed on the main bracket 8. The control board 11 is fixed on the main bracket 8 and the sub-bracket 10. The battery cell 9 is disposed in the internal space formed by the snap connection of the main bracket 8 and the sub-bracket 10.
[0024] Please refer to Figure 3 As shown in the figure, the control system of the light-emitting atomization device according to an embodiment of the present invention includes: a cold light sheet driving unit, a logic control unit, and a first electronic switch unit connected to the battery cell 9 on the control board 11. One end of the cold light sheet driving unit is connected to a key 12 and a sensor. The cold light sheet driving unit includes an inversion unit, a voltage transformation unit, a sampling feedback unit, a filtering unit, and a second electronic switch unit. The inversion unit is connected to the logic control unit and the voltage transformation unit. The output end of the voltage transformation unit is connected to the input end of the filtering unit and the sampling feedback unit. The filtering unit is connected to the second electronic switch unit.
[0025] In this embodiment, the inverter unit uses at least two MOS transistors or at least one triode. After receiving the square wave signal from the logic control unit, it modulates the input voltage (battery voltage) into an AC signal with a certain frequency (0.6 - 9Khz) and then transmits it to the input end of the voltage transformation unit. The voltage transformation unit uses a transformer 15 or a BUCK - BOOST IC (step - up / step - down chip), which can adjust the input voltage to an AC voltage with a preset voltage value (i.e., 60 - 150V) and then output it to the filtering unit to stabilize the voltage waveform. The sampling feedback unit samples the output voltage of the voltage transformation unit and then outputs it to the logic control unit. The logic control unit judges the output voltage of the sampling feedback unit and adjusts the control signal to regulate the output voltage to meet the working voltage and working frequency of the EL cold light sheet. Finally, the display effect of the EL cold light sheet is controlled by the second electronic switch unit. The logic control unit uses a 32 - bit MCU, which is directly powered by direct current (battery voltage), receives signals from the keys and sensors, and then sends different control signals to the inverter unit, the second electronic switch unit, and the first electronic switch unit to control the operation of the cold light sheet, the digital tube, and the heating element.
[0026] Due to the above - mentioned structure, the present utility model only needs to use a battery voltage with a relatively low voltage value (3 - 5V) as the input voltage, and through the inverter unit - voltage transformation unit, it can meet the requirement of high - voltage alternating current of 0.6 - 9Khz 60 - 150V. By adjusting the working frequency of the control signal or the circuit parameters of the inverter unit - voltage transformation unit by the logic control unit to regulate the working frequency of the voltage transformation unit, when the working frequency of the transformer is relatively high, the required size of the transformer can be reduced, which can meet the backlight requirements of thin - type electronic products. By adjusting the duty cycle of the control signal from the logic control unit, different brightness backlight control can also be achieved. The second electronic switch unit controls which area on the EL cold light sheet needs to be lit.
[0027] It should be noted that the technical solution of the present utility model is to convert low - voltage direct current into high - frequency alternating current to meet the application of the cold light sheet in the electronic atomization device. It does not rule out the possibility that the power supply of the electronic atomization device becomes alternating current or high - voltage direct current in the future. If the power supply is directly alternating current or high - voltage direct current, the voltage transformation unit can be retained and the inverter unit can be omitted, or the inverter unit can be retained and the voltage transformation unit can be omitted in the device.
