Technical Field

[0002] In the existing electronic atomization devices (such as electronic cigarettes), the displays for human-computer interaction mostly adopt digital tubes, LCDs, OLEDs, and flexible screens, etc. The display effect of the digital tube is limited by its implementation principle (the light-emitting beads arranged on the PCB emit light through the film paper with pre-printed patterns on the surface of the digital tube to form a light-emitting pattern), with strong granularity and uneven light emission; while LCDs, OLEDs, and flexible screens have relatively high costs, and digital tubes, LCDs, and OLEDs cannot be bent, which limits the product structure. In contrast, EL cold light sheets have the advantages of soft and uniform light sources, low cost, bendability, simple manufacturing process, and high product yield. However, due to the limited product volume (to ensure portability) and the requirement of keeping the circuit structure simple (without adding an AC-DC conversion circuit, low cost) for electronic cigarettes, they are all powered by a battery cell, which provides direct current and the voltage is much lower than the driving voltage of the EL cold light sheet.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1-3 As shown, a light-emitting electronic atomization device according to an embodiment of the present invention includes a housing, the housing 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 arranged below the upper cover 1 and encloses a cavity with the upper cover 1; an oil tank 4 is arranged in the housing, an atomization core 6 is arranged in the oil tank 4, the atomization core 6 has a heating element, and an oil storage cotton 5 is arranged between the atomization core 6 and the oil tank 4; an upper silica gel 3 is connected between the upper cover 1 and the oil tank 4, and a condensing cotton 2 is arranged 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, and 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 arranged in the outer shell 14, and the cold light sheet 13 is closely attached to the inner wall of the outer shell 14.
[0019] Further, it further includes a main bracket 8 and a sub-bracket 10 arranged in the housing. The top of the main bracket 8 is sleeved with a lower silica gel 7, the oil tank 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, and the battery cell 9 is arranged in the internal space formed by the snap connection of the main bracket 8 and the sub-bracket 10.
[0020] Please refer to Figure 3As shown in the figure, the control system of the light-emitting atomizing device according to the embodiment of the present invention includes: a cold light sheet driving unit, a logic control unit, and a first electronic switch unit that are arranged on the control board 11 and connected to the battery cell 9. 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.
[0021] In this embodiment, the inversion unit uses at least two MOS transistors or at least one triode. After receiving a square wave signal from the logic control unit, it modulates the input voltage (battery voltage) into an alternating current 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 and step-down chip), which can adjust the input voltage to an alternating current 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 then 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 through 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 key and the sensor, and then sends different control signals to the inversion 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.
[0022] Due to the above structure, the present invention only needs to use a battery voltage with a relatively low voltage value (3~5V) as the input voltage, and through the inversion unit - voltage transformation unit, it can meet the requirements 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 inversion 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 electronic products. By adjusting the duty cycle of the control signal from the logic control unit, different brightness backlight controls can also be achieved. Through the second electronic switch unit, which area on the EL cold light sheet needs to be lit can be controlled.
[0023] As Figure 3 shown, the control system of the light-emitting electronic atomizing device of the present invention includes a first electronic switch unit, a logic control unit, a cold light sheet driving unit, a key, and a sensor; the cold light sheet driving unit converts the direct current voltage into the driving voltage of the cold light sheet; The logic control unit receives signals from keys and sensors, and transmits direct current to the first electronic switch unit to control the working state of the heating element of the electronic atomization device; the logic control unit transmits direct current to the digital tube for lighting; the logic control unit is connected to the electroluminescent sheet driving unit and controls the working state of the electroluminescent sheet.
[0024] The electroluminescent sheet driving unit includes an inverter unit, a transformer unit, a sampling feedback unit, a filtering unit, and a second electronic switch unit. The inverter unit is connected to the logic control unit and the transformer unit. The output end of the transformer 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. After receiving the control signal from the logic control unit, the inverter unit converts the direct current voltage provided by the battery cell into an alternating current signal with a certain frequency and voltage peak value and transmits it to the input end of the transformer unit. The transformer unit adjusts the input voltage to an alternating current voltage with a preset voltage value and then outputs it to the filtering unit to stabilize the voltage waveform. The filtering unit outputs the stabilized alternating current after filtering. 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 then adjusts the control signal to regulate the output voltage, and controls the display effect of the electroluminescent sheet through the second electronic switch unit.
[0025] It should be noted that the technical solution of the present invention is to convert low-voltage direct current into high-frequency alternating current to achieve the application of the electroluminescent sheet in the electronic atomization device. The possibility that the power supply of the electronic atomization device becomes alternating current or high-voltage direct current in the future is not excluded. If the power supply is directly alternating current or high-voltage direct current, the transformer unit can be retained and the inverter unit can be omitted, or the inverter unit can be retained and the transformer unit can be omitted in the device.
