Description

Technical Field

[0001] The present invention relates to the technical field of electronic hookahs, and in particular to an atomization unit, an electronic hookah and a dry burning prevention detection method thereof. Background Art

[0002] Hookah is a tobacco product that originated in the Middle East. Over time, the development and application of electronic hookahs have significantly changed the smoking habits of many people and gradually replaced traditional hookahs. One type of electronic hookah uses a power-powered heating element to heat tobacco or tobacco paste to produce an inhalable aerosol, and the other type of electronic hookah uses a heating unit to heat the tobacco oil and tobacco liquid to produce an aerosol. Both of the above electronic hookahs have the advantages of fast start-up, easy portability, and cleanliness. Compared with traditional hookahs, they provide a cleaner and more controllable option, and therefore have gradually become the first choice for many people seeking an alternative to smoking. For electronic hookahs that heat tobacco oil and tobacco liquid, dry burning is prone to occur due to lack of oil when the tobacco oil and tobacco liquid are exhausted. Summary of the invention

[0003] The embodiment of the present invention provides an atomization unit, an electronic hookah and a dry burning prevention detection method thereof, so as to solve the problem that the existing device is prone to dry burning due to lack of oil.

[0004] To solve the above technical problems, an embodiment of the present invention provides a solution: an atomization unit is provided, which is used to atomize tobacco oil and is arranged on an electronic hookah body, including an oil tank and an atomization core. The atomization core can be detachably inserted into the oil tank. A conductive probe is arranged in the oil tank. When the atomization core is inserted into the oil tank, the oil outlet of the oil tank is connected to the oil inlet of the atomization core. The conductive probe can be electrically connected to the atomization core through tobacco oil to form a circuit loop.

[0005] After the atomization unit of the embodiment of the present invention is powered on, the atomization core heats the atomized smoke oil, the conductive probe and the conductive bracket have good conductivity, and the smoke oil has a certain conductivity. When the smoke oil contacts the conductive probe and the conductive bracket at the same time, an equivalent resistor is connected between the conductive probe and the conductive bracket, and a circuit loop can be formed. When the smoke oil is consumed, causing the smoke oil to not contact the conductive probe and / or the conductive bracket, the circuit loop between the conductive probe and the conductive bracket is disconnected. Therefore, by detecting the electrical signal of the circuit loop, such as the change in current, voltage or resistance, the on-off of the circuit loop between the conductive probe and the conductive bracket can be determined. When the circuit loop is disconnected, it can be determined that there is no oil. At the same time, by detecting the electrical signal of the circuit loop, the smoke oil consumption of the atomization unit can also be monitored to achieve the purpose of monitoring the working state of the atomization unit. The atomization unit of the embodiment of the present invention can avoid the dry burning of the atomization unit to bring a bad user experience, while improving the safety of use.

[0006] In order to solve the above technical problems, the present invention provides another solution: an electronic hookah is provided, comprising an electronic hookah body, the electronic hookah further comprising the atomization unit as described above, and the atomization unit is detachably arranged on the electronic hookah body.

[0007] In order to solve the above technical problems, the present invention provides another solution: providing an anti-dry burning detection method, which is applied to the electronic hookah as described above, and the anti-dry burning detection method comprises the steps of: Acquiring an electrical signal from an atomization unit; outputting a feedback signal according to the electrical signal; judging whether there is oil shortage according to the feedback signal; If it is determined according to the feedback signal that the atomization unit is in an oil-deficient state, the atomization unit is controlled to stop working.

[0008] The anti-dry burning detection method of the embodiment of the present invention, when applied to the electronic hookah as described above, can effectively avoid the dry burning phenomenon and improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides an atomization unit 100 for atomizing the e-hookah oil, comprising an oil tank 10 and an atomization core 20. The atomization core 20 is detachably embedded in the oil tank 10. The oil tank 10 is used to store the e-hookah oil. The atomization core 20 is used to energize and atomize the e-hookah oil. A conductive probe 30 is disposed in the oil tank 10. The atomization core 20 comprises a conductive bracket 21. When the atomization core 20 is embedded in the oil tank 10, the oil outlet 13 of the oil tank 10 is connected to the oil inlet 22 of the atomization core 20. The conductive probe 30 can form a circuit loop with the conductive bracket 21 through the e-hookah oil.

[0017] After the atomization unit 100 of the embodiment of the present invention is powered on, the atomization core 20 heats the atomized e-liquid, the conductive probe 30 and the conductive bracket 21 have good conductivity, and the e-liquid has a certain conductivity. When the e-liquid contacts the conductive probe 30 and the conductive bracket 21 at the same time, an equivalent resistor is connected between the conductive probe 30 and the conductive bracket 21, and a circuit loop can be formed. When the e-liquid is consumed, causing the e-liquid not to contact the conductive probe 30 and / or the conductive bracket 21, the circuit loop between the conductive probe 30 and the conductive bracket 21 is disconnected. Therefore, by detecting the electrical signal of the circuit loop, such as the change in current, voltage or resistance, the on-off of the circuit loop between the conductive probe 30 and the conductive bracket 21 can be determined. When the circuit loop is disconnected, it can be determined that there is no oil. At the same time, by detecting the electrical signal of the circuit loop, the e-liquid consumption of the atomization unit 100 can also be monitored to achieve the purpose of monitoring the working state of the atomization unit 100. The atomization unit of the embodiment of the present invention can avoid the dry burning of the atomization unit 100 to bring a bad user experience, while improving the safety of use.

[0018] It is understandable that the conductive probe 30 and the conductive bracket 21 can be made of metal materials or other materials with conductive ability.

[0019] Furthermore, in some embodiments, the conductive probe 30 is wrapped with an insulator 40 , the head of the conductive probe 30 is exposed from one side of the insulator 40 , and the portion of the conductive probe 30 wrapped by the insulator 40 can isolate the smoke oil from contacting the conductive probe 30 .

[0020] Specifically, the conductive probe 30 is rod-shaped, and the tail of the conductive probe 30 is fixed in the oil tank 10. The part of the conductive probe 30 wrapped by the insulator 40 can isolate the smoke oil from contacting the conductive probe 30. When the smoke oil level is high enough, the head of the conductive probe 30 can be immersed in the smoke oil; when the smoke oil is consumed and the oil level is reduced, the head of the conductive probe 30 is isolated from the smoke oil by the insulator 40, and the circuit loop between the conductive probe 30 and the conductive bracket 21 is disconnected. Therefore, by adjusting the length of the conductive probe 30 wrapped by the insulator 40, the amount of smoke oil used to judge the lack of oil can be adjusted. Among them, the insulator 40 can be made of rubber or other insulating materials.

[0021] In some embodiments, based on the above embodiments, a storage chip 50 is disposed in the fuel tank 10 .

[0022] Specifically, the model of the storage chip 50 is RJGT105T3, and the storage chip 50 is used to store the storage data of the atomization unit 100, wherein the storage data includes but is not limited to matching ID, total energy consumption data, usage energy consumption data, single energy consumption data, total e-liquid volume, cumulative usage time, number of puffs, e-liquid flavor, and nicotine content.

[0023] It can be understood that the energy consumption data represents the energy consumed by the oil in the oil chamber 11 of the oil tank 10 during the use and consumption process, and the energy consumption data is calculated as follows: J=I²*T, where I represents the current during the consumption process and T represents the time required for consumption. The total energy consumption data represents the energy consumed by the oil in the oil chamber 11 of the oil tank 10 from a full oil state to an empty oil state, and the calculation method is: J 总 =I²*T 总 ; Single energy consumption data refers to the energy consumed during a single use, and the calculation method is: J 单 =I²*T 单 , using energy consumption data J 用 It is obtained by accumulating the single energy consumption data during each use, and the total energy consumption data J 总 and use energy consumption dataJ 用 , we can get the remaining energy consumption data J 剩 , where the total energy consumption data J 总Indicates the energy consumption required for the atomization unit 100 to be used from the full oil state to the oil-free state. This data can be obtained by experiment during production and stored in the storage chip 50 in advance. The energy consumption data used indicates the energy consumption from the full oil state to the current oil state, and the remaining energy consumption data indicates the energy consumption required for the current oil state to be used to the oil-free state. If the remaining energy consumption data obtained cannot meet the needs of a single use, it can be determined that the oil in the oil tank 10 is short of oil. Specifically, the atomization unit 100 can be decoded and matched with the matching ID of the electronic hookah body through the matching ID stored in the storage chip 50. If the match is successful, it can be used normally; if the match is unsuccessful, it means that the atomization unit 100 is a non-matching product and cannot be used. The embodiment of the present invention detects and judges the energy consumption data, and the detection parameters are current I and time T. Compared with detecting the resistance value of the heating element 24 or the heating wire of the atomization unit 100 to judge the lack of oil, it can effectively avoid the detection error caused by the manufacturing process and material composition, resulting in different temperature coefficient differences, and can improve the detection accuracy.

[0024] Understandably, in other embodiments, a liquid level sensor may be provided in the oil chamber 11 of the mailbox, and then the total oil amount information in the storage chip 50 may be used to directly determine whether the oil is lacking by the oil amount, and other determination methods may be combined to improve the detection accuracy. In other embodiments, the lack of oil may also be determined by the accumulated usage time and the number of puffs. For example, if the number of puffs is set at the factory, if the maximum number of puffs is met, it may be determined that the oil is lacking and needs to be replaced in time.

[0025] As can be seen from the above, in addition to detecting the electrical signal of the circuit loop between the conductive probe 30 and the conductive bracket 21, the embodiment of the present invention can also avoid dry burning of the atomizer unit 100 by directly acquiring the storage data of the storage chip 50 in the oil tank 10 of the atomizer unit 100. This can avoid the misjudgment when the smoke oil does not contact the conductive probe 30 and / or the conductive bracket 21 due to the tilt of the atomizer unit 100, and further improve the detection accuracy.

[0026] Furthermore, the conductive support 21 is provided with the oil outlet 13 , the conductive support 21 is provided with oil absorbing cotton 23 , a heating element 24 is provided on one side of the oil absorbing cotton 23 , and an electrode of the heating element 24 is connected to the conductive support 21 .

[0027] Specifically, the oil tank 10 includes a shell, and an oil chamber 11 and a central channel 12 are provided in the shell. The central channel 12 runs through the shell from top to bottom. One side of the central channel 12 is used for the atomizer core 20 to be embedded, and the other side is used for air to enter. The oil outlet 13 connects the oil chamber 11 and the central channel 12, and the oil chamber 11 is used to store smoke oil. A seal 70 is provided in the central channel 12, and the seal 70 is used to block the oil outlet 13 of the oil chamber 11. When the atomizer core 20 is embedded in the central channel 12, the atomizer core 20 can push the seal 70 to move in the central channel 12, so that the smoke oil in the oil chamber 11 is transported from the oil outlet 13 to the atomizer core 20.

[0028] Understandably, when the atomizer core 20 is embedded in the oil tank 10, the conductive bracket 21 is in the central channel 12, and the oil in the oil tank 10 flows to the oil-absorbing cotton 23 inside the conductive bracket 21 through the oil inlet 22. The heating element 24 is energized to heat the oil absorbed on the oil-absorbing cotton 23, and the oil is heated and atomized into smoke. The smoke combines with the air entering from the central channel 12 to generate an aerosol.

[0029] It should be noted that the negative electrode of the heating element 24 is connected to the conductive bracket 21, which is equivalent to the negative electrode of the heating element 24 being grounded. Therefore, when the e-liquid is connected to the circuit loop of the conductive probe 30 and the conductive bracket 21, it is also grounded through the conductive bracket 21, and the positive electrode of the heating element 24 and the tail of the conductive probe 30 are electrically connected to the power supply end. It can be understood that the tail of the conductive probe 30 and the conductive bracket 21 can form an electrical shield through structure or material.

[0030] Please refer to Figure 3 Combined with Figure 1 In some embodiments, the present invention further provides an electronic hookah, which includes an electronic hookah body (not shown), and the electronic hookah also includes a control unit 200, a detection unit 300 and a power supply unit 400 arranged in the electronic hookah body, the control unit 200 is electrically connected to the power supply unit 400, the control unit 200 controls the power supply unit 400 to supply power, and the electronic hookah also includes the atomization unit 100 as described above, and the atomization unit 100 is detachably mounted on the electronic hookah body.

[0031] Specifically, the atomization unit 100 includes a conductive probe 30, a conductive bracket 21, a heating element 24 and a storage chip 50, and the control unit 200 includes a main control MCU, the model of the main control MCU is STM32G031C5T6, the main control MCU is electrically connected to the storage chip 50, the detection unit 300 is electrically connected to the conductive probe 30, and the detection unit 300 is used to detect the electrical signal of the circuit loop between the conductive probe 30 and the conductive bracket 21 and transmit the feedback signal to the main control MCU. Specifically, an electrical contact 60 can be set on the shell of the oil tank 10 of the atomization unit 100, and a plurality of electrical contacts 60 can be set on the electronic hookah body. When the two are installed together, the positive electrode of the heating element 24 and the tail of the conductive probe 30 can be electrically connected to the control unit 200 and the power supply unit 400 on the electronic hookah body through the electrical contacts, respectively, to achieve control and power supply. Among them, the power supply unit 400 is used as a power supply end, and a disposable battery or a recyclable battery can be used. In other embodiments, the atomization unit 100 may be electrically connected to the control unit 200 and the power supply unit 400 on the electronic hookah body through a port, an interface, etc.

[0032] Please refer to Figure 4 Combined with Figure 1 , the detection unit 300 of the embodiment of the present invention includes an operational amplifier U1, the model of the operational amplifier U1 is LMV321TP, the output end of the operational amplifier U1 can be electrically connected to the main control MCU through the output port OUT, the non-inverting input end IN+ and the negative input end IN- of the operational amplifier U1 are respectively connected to the comparison voltage module and the detection voltage module, and the detection voltage module can be electrically connected to the conductive probe 30 through the electrical contact. It can be understood that the comparison voltage module is used to input an electrical signal for comparison to the operational amplifier U1, which can be factory-set, and the detection voltage module is used to input an electrical signal of the circuit loop between the conductive probe 30 and the conductive bracket 21, and output a feedback signal through the output end of the operational amplifier U1 after comparison.

[0033] Specifically, the comparison voltage module includes a resistor R1 and a resistor R2, one end of the resistor R1 is connected to the power supply end, the other end of the resistor R1 is connected to the resistor R2, the other end of the resistor R2 is grounded, and the in-phase input terminal IN+ of the operational amplifier U1 is connected between the resistor R1 and the resistor R2; the detection voltage module includes a resistor R3, one end of the resistor R3 is connected to the power supply end, the other end of the resistor R3 can be electrically connected to the conductive probe 30 through the input port IN, and the reverse input terminal IN- of the operational amplifier U1 is connected between the resistor R3 and the input port IN. It can be seen that the input of the in-phase input terminal IN+ of the operational amplifier U1 is the voltage division between the resistor R1 and the resistor R3, and the input of the reverse input terminal IN- of the operational amplifier U1 is the voltage division between the resistor R3 and the circuit loop between the conductive probe 30 and the conductive bracket 21. Among them, the resistance values ​​of the resistors R1, R2 and R3 are factory preset and adjusted according to different needs.

[0034] It can be understood that when the smoke oil in the oil chamber 11 of the oil tank 10 of the atomization unit 100 is sufficient and the smoke oil level exceeds the insulator 40 outside the conductive probe 30, the conductive probe 30 is grounded through the conductive bracket 21, and the circuit loop between the conductive probe 30 and the conductive bracket 21 is turned on. At this time, the inverting input terminal IN- of the operational amplifier U1 of the detection unit 300 is equivalent to connecting an equivalent resistor. The input voltage of the inverting input terminal IN- of the operational amplifier U1 is generated by the voltage division of the resistor R3 and the equivalent resistor, and the input voltage of the non-inverting input terminal IN+ is generated by the voltage division of the resistor R1 and the resistor R2. At this time, due to the factory setting, the input voltage of the non-inverting input terminal IN+ of the operational amplifier U1 is greater than the input voltage of the inverting input terminal IN-. voltage, the output of the operational amplifier U1 outputs a high level; during the use of the electronic hookah, the smoke oil in the oil chamber 11 of the atomization unit 100 is continuously consumed. When the smoke oil level is lower than the insulator 40 outside the conductive probe 30, the circuit loop between the conductive probe 30 and the conductive bracket 21 is cut off, and the voltage of the inverting input terminal IN- of the operational amplifier U1 is determined by the resistor R3. The input voltage of the inverting input terminal IN- is equal to the voltage of the power supply terminal. The input voltage of the inverting input terminal IN+ is generated by the voltage division of the resistor R1 and the resistor R2. At this time, due to the factory setting, the input voltage of the inverting input terminal IN+ of the operational amplifier U1 is less than the input voltage of the inverting input terminal IN-, and the output of the operational amplifier U1 outputs a low level. The main control MCU determines whether there is a lack of oil in the oil chamber 11 at this time based on whether it is a high level or a low level.

[0035] Furthermore, the electronic hookah of the embodiment of the present invention further includes a prompt unit 500 disposed on the electronic hookah body, the prompt unit 500 is electrically connected to the main control MCU, and the prompt unit 500 is mainly used to prompt the user that the oil is insufficient to avoid dry burning and facilitate timely replacement. Understandably, the prompt unit 500 includes but is not limited to a buzzer and an indicator light, and the prompt unit 500 includes but is not limited to a voice prompt and a visual prompt.

[0036] The electronic hookah of the embodiment of the present invention can stop working in time to prevent dry burning when oil is lacking, and prompt the user to replace it, thereby effectively improving the user's experience.

[0037] Please refer to Figure 5 An embodiment of the present invention further provides a dry burning prevention detection method, which is applied to the electronic hookah as described above, and the dry burning prevention detection method comprises the steps of: S101: Acquire the electrical signal of the atomization unit 100.

[0038] Understandably, when the atomization unit 100 and the electronic hookah body are installed together, the input port IN of the detection unit 300 can be electrically connected to the conductive probe 30 of the atomization unit 100. If at this time there is enough smoke oil in the oil chamber 11 of the oil tank 10 of the atomization unit 100, the smoke oil acts as an equivalent resistor to make the conductive bracket 21, the smoke oil, and the conductive probe 30 form a circuit loop, and the electrical signal input to the inverting input terminal IN- of the operational amplifier U1 is the voltage divided by the resistor R3 and the circuit loop; if at this time there is too little smoke oil in the oil chamber 11 of the oil tank 10 of the atomization unit 100, the conductive bracket 21, the smoke oil, and the conductive probe 30 do not form a circuit loop, which is equivalent to 0 voltage, and the electrical signal input to the inverting input terminal IN- of the operational amplifier U1 is the voltage across the resistor R3.

[0039] S102: Output a feedback signal according to the electrical signal.

[0040] It can be understood that when the input voltage of the non-inverting input terminal IN+ of the operational amplifier U1 of the detection unit 300 is less than the input voltage of the inverting input terminal IN-, the feedback signal output by the output terminal of the operational amplifier U1 is a low level; when the input voltage of the non-inverting input terminal IN+ of the operational amplifier U1 is greater than the input voltage of the inverting input terminal IN-, the feedback signal output by the output terminal of the operational amplifier U1 is a high level.

[0041] S103: Determine whether there is oil shortage according to the feedback signal.

[0042] Understandably, the main control MCU receives the feedback signal and makes a judgment.

[0043] If the feedback signal is at a low level, it is determined that the atomization unit 100 is in an oil-deficient state, and then step S104 is executed: the atomization unit 100 is controlled to stop working.

[0044] Furthermore, while controlling the heating element 24 of the atomizing unit 100 to stop heating, step S105 can also be performed: controlling the prompting unit 500 to work, so as to prompt the user to replace the atomizing unit 100 in time.

[0045] If the feedback signal is at a high level, it is determined that the atomization unit 100 is not in an oil-deficient state, and then step 106 is executed: controlling the atomization unit 100 to work normally.

[0046] The anti-dry burning detection method according to an embodiment of the present invention further comprises the steps of: S201: Acquire storage data of the storage chip 50.

[0047] Understandably, the stored data includes but is not limited to matching ID, total energy consumption data, usage energy consumption data, single energy consumption data, total e-liquid volume, cumulative usage time, number of puffs, e-liquid flavor, and nicotine content.

[0048] Specifically, the atomization unit 100 can be decoded and matched with the matching ID of the electronic hookah body through the matching ID stored in the storage chip 50. If the match is successful, it can be used normally; if the match is unsuccessful, it means that the atomization unit 100 is a non-matching product and cannot be used. The main control MCU can obtain the stored data every time the machine is turned on or used.

[0049] S202: Obtaining remaining energy consumption data according to the total energy consumption data and the used energy consumption data.

[0050] It can be understood that the main control MCU can obtain the remaining energy consumption data through calculation based on the total energy consumption data and the used energy consumption data obtained by cumulative calculation.

[0051] S203: Determine whether there is oil shortage according to the remaining energy consumption data.

[0052] Understandably, if the main control MCU determines that the atomization unit 100 is in an oil-deficient state according to the remaining energy consumption data, step S204 is executed: controlling the atomization unit 100 to stop working.

[0053] Further, based on the above embodiment, the anti-dry burning detection method of one embodiment of the present invention further includes the steps of: S301: Determine whether there is a shortage of oil according to the remaining energy consumption data, and determine whether there is a shortage of oil according to the feedback signal.

[0054] If the main control MCU determines that the atomization unit 100 is in an oil-deficient state according to the feedback signal, and if the atomization unit 100 is in an oil-free state according to the remaining energy consumption data, step S302 is executed: the atomization unit 100 is controlled to continue working, which can effectively avoid misjudgment caused by the tilt of the atomization unit 100.

[0055] The anti-dry burning detection method of the embodiment of the present invention, when applied to the electronic hookah as described above, can effectively avoid the dry burning phenomenon and improve the user experience.
