For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0029] Please refer to Figures 1-4 , the first embodiment of the present utility model provides an electronic atomizer 1. The electronic atomizer 1 includes a housing 20. A fuel storage chamber 21 and a control module 22 are provided in the housing 20. An atomization core 212 and an oil quantity sensing member 213 are provided in the fuel storage chamber 21. The oil quantity sensing member 213 is arranged in the direction of the e-liquid flowing to the atomization core 212. The control module 22 is electrically connected to the oil quantity sensing member 213 and the atomization core 212 respectively. The oil quantity sensing member 213 senses the change in the oil quantity in the fuel storage chamber 21, and the control module 22 controls the on-off of the circuit of the atomization core 212 according to the change in the oil quantity.
[0030] It can be understood that by electrically connecting the control module 22 to the oil quantity sensing member 213, the oil quantity sensing member 213 monitors the oil quantity to obtain oil quantity information. By presetting an oil quantity threshold, when the remaining oil quantity is lower than the oil quantity threshold, the oil quantity sensing member 213 will trigger a switch action, and the circuit of the atomization core 212 will be disconnected. This oil quantity threshold corresponds to the critical value of insufficient e-liquid, thus playing a role in preventing dry burning. When the oil quantity information is greater than or equal to the oil quantity threshold, the circuit of the atomization core 212 remains connected. As a specific implementation manner, the oil quantity sensing member 213 serves as an input device, and the control module 22 can adopt a microcontroller or a programmable logic controller to control switch elements such as transistors or relays based on the above comparison results to achieve automatic control. The oil quantity sensing member 213 can be applicable to different environmental conditions, and the oil quantity sensing member 213 can accurately reflect the actual remaining amount of e-liquid. By the oil quantity sensing member 213 sensing the change in the oil quantity in the fuel storage chamber 21, the control module 22 controls the on-off of the circuit of the atomization core 212 according to the change in the oil quantity, thereby establishing a corresponding relationship between the oil quantity information and the on-off of the circuit of the atomization core 212, improving the accuracy of preventing dry burning, and providing more effective protection for the safety of the electronic atomizer 1 device.
[0031] Please refer to Figure 1 and Figure 2, Further, the fuel quantity sensing element 213 is a humidity sensor and / or a liquid level sensor. The humidity sensor includes a capacitive humidity sensor and / or a resistive humidity sensor. When the humidity sensor senses that the fuel quantity changes to be lower than a preset humidity threshold, the electronic atomizer 1 gives a prompt. When the fuel quantity sensing element 213 is a liquid level sensor, when the liquid level sensor monitors that the fuel quantity changes to the point where the e-liquid level is lower than a preset liquid level threshold, the electronic atomizer 1 gives a prompt.
[0032] As a preferred embodiment, the fuel quantity sensing element 213 is a humidity sensor. By using a humidity sensor as the fuel quantity sensing element 213, since different fuel quantities correspond to different humidities, the fuel quantity change can be monitored by using humidity. The humidity sensor can effectively measure humidity, and thus fuel quantity monitoring can be achieved. The capacitive humidity sensor measures humidity based on capacitance changes. The dielectric constant of the humidity-sensitive capacitor changes with the change of the ambient humidity, thereby affecting its capacitance. By presetting a humidity threshold, which is a humidity critical value for insufficient e-liquid quantity set in advance. As a specific embodiment, the control module 22 may be provided with a comparison circuit. When the comparison circuit compares and obtains that the capacitance or voltage output by the capacitive humidity sensor is lower than the capacitance or voltage corresponding to the preset humidity threshold, the capacitance of the capacitive humidity sensor will trigger a switch action. The control module 22 changes the output high / low level signal to control the disconnection of the atomizing core 212 circuit, and the control module 22 changing the output high / low level signal can also be used to trigger the electronic atomizer 1 to give a prompt; when the ambient humidity where the capacitive humidity sensor is located is greater than or equal to the preset humidity threshold, the capacitance of the capacitive humidity sensor does not trigger a switch action, and the atomizing core 212 circuit remains connected; the resistive humidity sensor measures humidity based on the change of the resistance value of the humidity-sensitive resistor. The resistance value of the humidity-sensitive resistor changes with the change of the ambient humidity. As a specific embodiment, the control module 22 may be provided with a comparison circuit. The comparison circuit converts the resistance value of the resistive humidity sensor into a voltage and compares it with the voltage corresponding to the preset humidity threshold, so as to change the output high and low level states according to the comparison result. When the voltage corresponding to the resistance of the resistive humidity sensor is lower than the voltage corresponding to the preset humidity threshold, the resistance of the resistive humidity sensor will trigger a switch action. The control module 22 changes the output high / low level signal, and the atomizing core 212 circuit is disconnected. The control module 22 changing the output high / low level signal can also be used to trigger the electronic atomizer 1 to give a prompt; when the ambient humidity where the resistive humidity sensor is located is greater than or equal to the humidity threshold, the resistance of the resistive humidity sensor does not trigger a switch action, and the atomizing core 212 circuit remains connected. Thus, fuel quantity monitoring can be achieved based on humidity using the above physical characteristics. These humidity sensors have the advantages of high precision, fast response speed, low power consumption, and are more suitable for the long-term battery-powered operation of the electronic atomizer 1, and can measure humidity more accurately.
[0033] As another preferred embodiment, the oil quantity sensor 213 is a liquid level sensor. It can be understood that the liquid level is related to the oil quantity, and there is a corresponding relationship between the output signal of the liquid level sensor and the liquid level. Based on the change of the liquid level, the output signal of the liquid level sensor is different. By monitoring the liquid level, the oil quantity can be monitored. By presetting a liquid level threshold, which is the critical liquid level value for insufficient e-liquid quantity set in advance. As a specific embodiment, the control module 22 may be provided with a comparison circuit. When the liquid level monitored by the liquid level sensor is greater than or equal to the preset liquid level threshold, the comparison circuit compares and obtains that the voltage output by the liquid level sensor is lower than the voltage corresponding to the preset liquid level threshold. The output signal of the liquid level sensor will trigger the switch to act, and the control module 22 changes the output high / low level signal to control the circuit of the atomizing core 212 to disconnect. And the control module 22 changing the output high / low level signal can also be used to trigger the electronic atomizer 1 to give a prompt. When the liquid level monitored by the liquid level sensor is greater than or equal to the preset liquid level threshold and the liquid level sensor does not trigger the switch to act, the circuit of the atomizing core 212 remains connected. The liquid level sensor can monitor the height of the e-liquid level, avoid dry burning of the electronic atomizer 1, and ensure the safe and effective operation of the electronic atomizer 1.
[0034] It should be noted that the oil quantity sensor 213 can also simultaneously adopt a humidity sensor and a liquid level sensor. By combining the advantages of the two sensors, more accurate oil quantity monitoring can be achieved, preventing dry burning of the electronic atomizer 1 device.
[0035] Please combine Figure 3 and Figure 4 , further, an oil storage cotton 211 is arranged in the oil storage chamber 21. The oil storage cotton 211 is arranged around the atomizing core 212, and the oil quantity sensor 213 is arranged on the side of the oil storage cotton 211 close to the atomizing core 212.
[0036] It can be understood that by arranging the oil storage cotton 211 in the oil storage chamber 21, the oil storage cotton 211 can absorb and store a certain amount of e-liquid, ensuring sufficient e-liquid supply during use. And since the oil storage cotton 211 is arranged around the atomizing core 212, the fibers of the oil storage cotton 211 can transport the e-liquid to the atomizing core 212 through capillary action, enabling the atomizing core 212 to continuously atomize the e-liquid and maintaining a moist environment around the atomizing core 212, avoiding the dry burning phenomenon caused by insufficient e-liquid supply. At the same time, the oil storage cotton 211 can also prevent e-liquid leakage, keep the inside of the electronic atomizer 1 clean and dry, and avoid equipment damage and inconvenience in use caused by leakage. The oil quantity sensor 213 is arranged on the side of the oil storage cotton 211 close to the atomizing core 212, enabling the oil quantity information monitored by the oil quantity sensor 213 to be the oil quantity information on the side of the oil storage cotton 211 close to the atomizing core 212, thus truly reflecting the sufficiency of the e-liquid supplied to the atomizing core 212.
[0037] It should be noted that, as a variant specific implementation manner, the oil storage cotton 211 is not provided in the oil storage chamber 21, and the oil quantity sensing member 213 is directly arranged in the oil storage chamber 21 in the direction of the e-liquid flowing towards the atomization core 212. Through the design without the oil storage cotton 211, the residue of the e-liquid on the oil storage cotton 211 can be avoided, the use efficiency of the e-liquid can be improved, and the remaining state of the e-liquid can be more intuitively displayed.
[0038] Please refer to Figures 3-5 , further, a plurality of oil quantity sensing members 213 are arranged in the oil storage chamber 21, and the plurality of oil quantity sensing members 213 are arranged around the atomization core 212.
[0039] It can be understood that by arranging a plurality of oil quantity sensing members 213 in the oil storage chamber 21, the plurality of oil quantity sensing members 213 can reduce the deviation that may be caused by relying on a single component for monitoring. The plurality of oil quantity sensing members 213 are arranged around the atomization core 212, and can fully and comprehensively monitor the oil quantity around the atomization core 212, and the obtained oil quantity information is more representative and targeted.
[0040] Please continue to refer to Figures 3-5 , further, the atomization core 212 includes a support tube 2121, a wicking cotton 2122 and a heating wire 2123. The wicking cotton 2122 and the support tube 2121 are sleeved on the outer side of the heating wire 2123 in sequence along the direction from the inside to the outside; the support tube 2121 is provided with an oil guiding hole 2124, and the oil quantity sensing member 213 is arranged corresponding to the oil guiding hole 2124.
[0041] It can be understood that by setting the atomization core 212 to be composed of the support tube 2121, the wicking cotton 2122 and the heating wire 2123, the support tube 2121 provides an accommodation space for the wicking cotton 2122 and the heating wire 2123. The wicking cotton 2122 sleeved on the outer side of the heating wire 2123 can guide the e-liquid to the heating wire 2123 for heating by the heating wire 2123. The corresponding positions of the oil guiding hole 2124 and the oil quantity sensing member 213 enable the oil quantity sensing member 213 to monitor the oil quantity information at the place where the e-liquid enters the support tube 2121 through the oil guiding hole 2124. Whether the oil quantity at this place is sufficient for the heating wire 2123 to heat the e-liquid entering the support tube 2121 through the oil guiding hole 2124 is reflected, so it is more representative.
[0042] Please refer to Figure 3 and Figure 5 , further, a gap is arranged between the oil guiding hole 2124 and the oil quantity sensing member 213.
[0043] It can be understood that by arranging a gap between the oil guiding hole 2124 and the oil quantity sensing member 213, the oil guiding hole 2124 and the oil quantity sensing member 213 do not directly contact, and the existence of the gap can keep the e-liquid flowing smoothly from the oil guiding hole 2124 into the support tube 2121.
[0044] Please combine with Figure 1 and Figure 2 , furthermore, the electronic atomizer 1 further includes a prompting device 30, and the prompting device 30 is in signal connection with the control module 22.
[0045] It can be understood that by setting the prompting device 30, when the oil quantity information detected by the oil quantity sensor 213 is lower than a preset oil quantity threshold, the control module 22 is triggered to generate a refueling prompt control signal. As a specific implementation manner, the control module 22 changes the output high / low level signal as the refueling prompt control signal. After receiving the refueling prompt control signal, the prompting device 30 connected to the control module 22 issues a refueling prompt message to remind the user to refuel in time.
[0046] Furthermore, the prompting device 30 is a voice prompting device 30 and / or a display prompting device 30.
[0047] It can be understood that by setting the prompting device 30 as a voice prompting device 30 and / or a display prompting device 30, the prompt message can be presented in the form of auditory information and visual information, so that the prompting form is more diverse and can fully meet the user's prompting needs in different application scenarios.
[0048] Please continue to combine with Figure 1 and Figure 2 , furthermore, the housing 20 is provided with a prompt control switch 23, and the prompt control switch 23 is electrically connected to the prompting device 30.
[0049] It can be understood that in addition to the control module 22 controlling the prompting device 30 to turn off the refueling prompt message, by setting the prompt control switch 23, the prompt control switch 23 can control the on / off of the prompting device 30. The user can use the prompt control switch 23 to independently choose whether to turn off the refueling prompt message, which can meet the user's self-control needs and is more user-friendly.

At the same time, the oil storage cotton can also prevent e-liquid leakage, keep the inside of the electronic atomizer clean and dry, and avoid equipment damage and inconvenient use caused by leakage. The oil quantity sensor is arranged on the side of the oil storage cotton close to the atomization core, which can make the oil quantity information monitored by the oil quantity sensor be the oil quantity information on the side of the oil storage cotton close to the atomization core, thus truly reflecting the sufficiency of the e-liquid supplied to the atomization core.
