Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application firstly proposes an electronic atomization device, as shown in fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of the electronic atomization device. The electronic atomization device 101 of the embodiment at least includes a first sensor 102, an atomizer 103, and a processor 104, and both the first sensor 102 and the atomizer 103 are electrically connected to the processor 104. The first sensor 102 is configured to detect a liquid leakage condition of the atomizer 103, and the processor 104 is configured to control the electronic atomization device 101 to operate according to a first detection result of the first sensor 102, so as to control the electronic atomization device 101 to be powered off when the atomizer 103 leaks.
The first sensor 102 of this embodiment may be disposed on a side of the processor 104 close to the liquid storage cavity of the atomizer 103 or a cartridge (not shown), and is configured to detect whether the liquid storage cavity of the atomizer 103 or the cartridge leaks onto the processor 104.
Of course, in other embodiments, the location of the first sensors and the processor and the number of first sensors may not be limited. For example, a first sensor may be provided at a location on the nebulizer that is not integrally closed to detect leakage at the location on the nebulizer that is not integrally closed.
Further, the electronic atomization device 101 of the embodiment further includes a power source 105, and the power source 105 supplies power to the first sensor 102, the atomizer 103, the processor 104, and other components; the processor 104 realizes the function control of the power supply 105 on, off, on time and the like, and realizes the control of the working states of the atomizer 103 and the first sensor 102; the power supply 105 and the atomizer 103 are detachably connected.
The application further provides a liquid leakage monitoring method of the electronic atomization device, which can be used for the electronic atomization device 101. As shown in fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a liquid leakage monitoring method for an electronic atomization device according to the present application. The liquid leakage monitoring method of the present embodiment includes the following steps S201 to S204.
Step S201: after the electronic atomization device 101 is powered on and in a standby state, the processor 104 obtains a first detection result of the first sensor 102.
After the power source 105 is assembled to the electronic atomization device 101, the processor 104 is electrically connected to the battery 105, the processor 104 controls the power source 105 to be turned on, that is, the electronic atomization device 101 is powered on, and when the electronic atomization device 101 is in a powered-on state, the power source 105 supplies power to the first sensor 102, the processor 104 and the atomizer 103.
After the electronic atomization device 101 is powered on and is not used for pumping, the electronic atomization device is in a standby state; after the electronic atomization device 101 is powered on, the electronic atomization device is in a suction state during suction, and the processor 104 may control the atomizer 103 to perform heating atomization in the suction state.
The processor 104 obtains a first detection result of the first sensor 102 when the electronic atomization device 101 is powered on and in a standby state, that is, when the atomizer 103 does not heat and atomize the tobacco tar or the condensed liquid droplets, so as to perform liquid leakage detection before the atomizer 103 heats and atomizes.
Alternatively, the first sensor 102 of the present embodiment may be a capacitor. When the smoke or the condensed liquid drops on the capacitor, the capacitance value of the capacitor is increased, and the processor 104 obtains the current capacitance value of the capacitor as the first detection result.
The capacitor of the present embodiment may be specifically a capacitive analog microphone or a capacitive pressure sensor.
In another embodiment, the first sensor may be a capacitive pressure sensor, the capacitive pressure sensor includes a capacitor and a measuring circuit, the capacitor uses a circular metal film or a metal-plated film as an electrode, when the film deforms by sensing pressure, capacitance formed between the film and the fixed electrode changes, and an electrical signal in a certain relationship with the capacitance can be output through the measuring circuit. The processor obtains the electric signal of the measuring circuit as a first detection result.
In another embodiment, the first sensor may also be a photoelectric sensor, the photoelectric sensor includes a light emitting end and a light receiving end, and when there is a liquid leakage, a medium in front of the light emitting end and the light receiving end is changed into smoke oil or condensed liquid drops from air, so that the refractive index of light changes. The processor obtains the optical refractive index of the photoelectric sensor as a first detection result.
Optionally, the processor 104 of the present embodiment obtains the first detection result of the first sensor 102 at preset time intervals. The preset time interval may be 3 to 20 minutes, and the preset time interval may be specifically 3 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, or the like.
From the above analysis, it is known that the capacitance of the capacitor increases when smoke or condensate drips on the capacitor. However, when the electronic atomization apparatus 101 is in a standby state, the capacitance value of the capacitor changes relatively slowly, and the single detection accuracy is not high. Only when the leakage is accumulated to a certain degree, the leakage can be accurately judged. The capacitor described above may also have the characteristics of: after the smoke oil or the condensed liquid drops are dripped on the capacitor for a period of time, the capacitor almost has resistance characteristics, and the resistance becomes smaller and smaller along with the increase of time and humidity.
Therefore, in the present embodiment, by detecting the leakage of the atomizer 103 at regular intervals, not only the real-time leakage monitoring of the atomizer 103 can be performed, but also the accuracy of the leakage monitoring can be improved.
If the first sensor 102 fails to detect the first detection result, the output of the power supply 105 may be turned off if it is determined that the first sensor 102 has a serious liquid leakage.
Step S202: the processor 104 judges whether the atomizer 103 leaks according to the first detection result. If so, the process proceeds to step S203, and if not, the process proceeds to step S204.
Specifically, the processor 104 determines whether the atomizer 103 leaks according to the capacitance value of the capacitor.
Alternatively, the present embodiment may implement the step S202 by a method as shown in fig. 3, and the method of the present embodiment includes the following steps S301 to S304.
Step S301: the processor 104 obtains a current capacitance value of the capacitor as a first capacitance value, and obtains a first difference value between the first capacitance value and a pre-stored capacitance value.
The processor 104 obtains the current capacitance value of the capacitor as a first capacitance value An, and obtains a first difference Δ a = An-a between the first capacitance value An and the pre-stored capacitance value a.
The pre-stored capacitance value a is the capacitance value when the capacitor is in a normal state, i.e. not soaked by the soot or the condensate droplets. The pre-stored capacitance value a can be detected and obtained by an electronic detection device before the electronic atomization device 101 is assembled.
The pre-stored capacitance value A can be 12pF-20pF, and the pre-stored capacitance value A can be 12pF, 14pF, 16pF, 18pF, 20pF and the like.
In other embodiments, the pre-stored capacitance value a may be set according to the type and structure of the capacitor.
Step S302: the processor 104 determines whether the first difference is greater than a first predetermined difference. If yes, go to step S303, otherwise go to step S304.
This first predetermined difference can be 0.5pF-2pF, and this first predetermined capacitance value specifically can be 0.5pF, 1pF, 1.5pF and 2pF etc..
Step S303: processor 104 determines that nebulizer 103 is leaking.
If the processor 104 determines that the first difference Δ a between the current capacitance An of the capacitor and the preset capacitance a is greater than the first preset difference, it is determined that the atomizer 103 is leaking, and at this time, the atomizer 103 is not suitable for heating and atomizing, otherwise the above-mentioned safety problem may be caused.
Step S304: the processor 104 determines that the nebulizer 103 is not leaking, and stores the first capacitance value.
If the processor 104 determines that the first difference Δ a between the current capacitance An of the capacitor and the preset capacitance a is smaller than or equal to the first preset difference, it is determined that the atomizer 103 does not leak liquid, and at this time, the atomizer 103 may perform heating atomization.
Step S203: the processor 104 controls the electronic atomization device 101 to power down.
If the processor 104 determines that the atomizer 103 leaks, the power supply 105 is turned off to control the electronic atomization device 101 to be powered off, so as to avoid safety problems caused by heating atomization. Alternatively, step S201 may also be performed at preset time intervals after step S203.
Step S204: the processor 104 controls the atomizer 103 to perform heating atomization when the electronic atomization apparatus 101 is in the suction state.
If the processor 104 judges that the atomizer 103 does not leak liquid, the electronic atomization device 101 is waited for being sucked, and the atomizer 103 is controlled to be heated and atomized when the electronic atomization device 101 is in a suction state.
Different from the prior art, in this embodiment, after the electronic atomization device 101 is powered on and when the electronic atomization device is in a standby state, the first sensor 102 and the processor 104 perform leakage detection on the atomizer 103, and the electronic atomization device 101 is controlled to be powered off when leakage of the atomizer 103 is detected, so that safety problems such as smoking of smoke liquid caused by leakage, short circuit of a battery, increase of self-discharge and explosion caused by failure of a battery charging function can be avoided, and the safety and the service life of the electronic atomization device 101 can be improved.
The present application further proposes an electronic atomization device of a second embodiment, and as shown in fig. 4, an electronic atomization device 401 of this embodiment further includes a second sensor 402 on the basis of the electronic atomization device 101, and the second sensor 402 is electrically connected to a processor 403. The power supply 404 further powers the second sensor 402. The first sensor 406 of the electronic atomizer 401 of the present embodiment is similar to the first sensor 102 described above.
The second sensor 402 of the present embodiment is provided in the airway of the electronic atomization device 401 to detect the suction state of the electronic atomization device 401.
The electrical characteristics of the first sensor 406 are different when the electronic atomization device 401 is in the suction state and the standby state, and in order to further improve the accuracy of leakage monitoring, the application provides a leakage monitoring method for an electronic atomization device according to a second embodiment, which can be used for leakage monitoring of the electronic atomization device 401. As shown in fig. 5, the liquid leakage monitoring method of the present embodiment includes the following steps S501 to S508.
Step S501: after the electronic atomization device 401 is powered on and in a standby state, the processor 403 acquires a first detection result of the first sensor 406.
Step S501 is the same as step S201 described above, and is not described here again.
Step S502: the processor 403 determines whether the atomizer 405 leaks according to the first detection result. If yes, step S503 is executed, and if no, step S505 is executed.
The method for determining whether the atomizer 405 leaks according to the first detection result by the processor 403 in this embodiment is the same as the above steps S301-S304, and is not repeated here.
Step S503: the processor 403 controls the electronic nebulizing device 401 to be powered off.
Step S501 is the same as step S203 described above, and is not described here.
Of course, in other embodiments, the processor may also perform a liquid leakage prompt when determining that the atomizer is leaking liquid. For example, the processor controls an indicator light of the electronic atomization device to emit light or flash, or the processor controls a sound module of the electronic atomization device to emit warning sound, or the processor controls other components of the electronic atomization device to generate warning information in the form of sound, light, electricity and the like, so as to remind a user.
Step S504: the second sensor 402 detects the suction state of the electronic atomization device 401.
After the electronic atomization device 401 is powered on, the second sensor 402 detects the suction state of the electronic atomization device 401. As can be seen from the above analysis, when the electronic atomization device 401 is powered on and then in the suction state, the atomizer 405 is heated and atomized, and therefore the suction state of the electronic atomization device 401 needs to be determined, so as to avoid that the atomizer 405 is heated and atomized when the electronic atomization device 401 is in the standby state, which can reduce the waste of smoke oil or condensed liquid droplets and save electric energy.
Optionally, the second sensor 402 of this embodiment may be a digital microphone, which includes a capacitor and a measuring circuit, where the capacitance of the capacitor changes with the change of the airflow pressure, and an electrical signal in a certain relationship with the capacitance may be output through the measuring circuit. The processor 403 detects the suction state from the electrical signal of the measuring circuit.
In another embodiment, the second sensor 402 may be another airflow sensing device.
Alternatively, the processor 403 of the present embodiment detects the suction state at preset time intervals. The preset time interval may be 3 to 20 minutes, and the preset time interval may be specifically 3 minutes, 5 minutes, 10 minutes, 15 minutes, 20 minutes, or the like. In this way, real-time monitoring of the pumping status can be achieved.
It should be noted that, after the electronic atomization device 401 is powered on, the detection operation of the first sensor 406 and the detection operation of the second sensor 402 are performed independently, and when the processor 403 determines that the electronic atomization device 401 is in the suction state, the processor 403 interrupts the above steps S501 and S502, and proceeds to step S505.
Step S505: the processor 403 determines whether the electronic atomization device 401 is in the suction state according to the detection result of the second sensor 402. If yes, go to step S506, otherwise go to step S504.
Alternatively, the present embodiment may implement the step S505 by using a method as shown in fig. 6, and the method of the present embodiment includes the following steps S601 to S604.
Step S601: the processor 403 acquires the output voltage of the second sensor 402.
When the electronic atomization device 401 is in a suction state, the output level of a measurement circuit of the digital microphone is high; when the suction is stopped, that is, the electronic atomization device 401 is in a standby state, the output of the measurement circuit is low.
Step S602: the processor 403 determines whether the output voltage is high. If yes, go to step S603, otherwise go to step S604.
Step S603: the processor 403 determines that the electronic atomizer 401 is in a suction state.
If the output voltage of the measurement circuit is at a high level, the electronic atomization device 401 is considered to be in the suction state, and step S506 is executed to monitor liquid leakage in the suction state.
Step S604: the processor 403 determines that the electronic atomizer 401 is in a standby state.
If the output voltage of the measurement circuit is at a low level, the electronic atomization device 401 is considered to be in a standby state, and step S504 is executed at preset time intervals, so as to detect the suction state of the electronic atomization device 401 through the second sensor 402.
Further, when the smoke or the condensed liquid drops on the digital microphone, the digital microphone may generate an abnormal high output level, but the voltage value of the high output level is different from the voltage value of the high output level in the pumping state. The processor 403 can therefore determine whether the electronic atomizer device 401 is in the suction state or the liquid leakage state according to the specific voltage value of the high level.
Step S506: the processor 403 obtains a second detection result of the first sensor 406.
Step S506 is the same as step S201, and the first sensor 406 may be the first sensor 102, which is not described herein.
Step S507: the processor 403 determines whether the atomizer 405 leaks in the suction state according to the second detection result. If yes, go to step S503, otherwise go to step S508.
Alternatively, the first sensor 406 may be a capacitor, which is the same as the first sensor 102, and the present embodiment may implement the step S507 by the method shown in fig. 7, where the method of the present embodiment includes the following steps S701 to S704.
S701: the processor 403 obtains the current capacitance value of the capacitor as the second capacitance value, and obtains a first difference value between the second capacitance value and the stored first capacitance value.
The processor 403 obtains the current capacitance value of the capacitor as the first capacitance value Bn, and obtains a first difference Δ B = Bn-B between the second capacitance value Bn and the stored first capacitance value B.
As can be seen from the above analysis, the first capacitance value B is the capacitance value of the capacitor detected when the electronic atomization device 401 is in the standby state and no liquid leaks.
S702: the processor 403 determines whether the second difference is greater than a second predetermined difference. If not, step S703 is executed, and if yes, step S704 is executed.
The second predetermined difference may be 0.5pF-2pF, and the pre-stored capacitance may be specifically 0.5pF, 1pF, 1.5pF, and 2 pF.
S703: processor 403 determines that nebulizer 405 is leaking in the suction state.
During the pumping phase, the change in capacitance of the capacitor caused by leakage is not significant. Therefore, if the processor 403 determines that the first difference Δ B between the current capacitance Bn of the first sensor 406 and the preset capacitance B is smaller than or equal to the second preset difference, it is determined that the atomizer 405 leaks in the suction state, and at this time, the atomizer 405 is not suitable for heating and atomizing, otherwise the above-mentioned safety problem may be caused.
S704: processor 403 determines that nebulizer 405 is not leaking in the suction state.
During the pumping phase, the change in capacitance of the capacitor is a drastic process if it is pumped normally. Therefore, if the processor 403 determines that the first difference Δ B between the current capacitance Bn of the capacitor and the preset capacitance B is greater than the second preset difference, it is determined that the atomizer 405 is not leaking liquid, and at this time, the atomizer 405 may perform heating atomization.
If the processor 403 determines that the atomizer 405 leaks in the suction state, step S503 is executed to control the atomizer 405 to continue to maintain the non-operating state, so as to avoid safety problems caused by heating atomization. In addition, if the processor 403 determines that the atomizer 405 leaks in the suction state, the output of the power supply 404 may be turned off to ensure that no current is generated in the whole electronic atomization device 101, thereby further increasing the safety.
Step S508: processor 403 controls nebulizer 405 to perform thermal nebulization.
If the processor 403 determines that the atomizer 405 is not liquid-tight in the suction state, the atomizer 405 is controlled to heat and atomize.
Different from the prior art, in this embodiment, after the electronic atomization device 401 is powered on, in a standby state and when the electronic atomization device is in the standby state, the first sensor 406 and the processor 403 perform first liquid leakage detection on the atomizer 405, and when liquid leakage of the atomizer 405 is detected, the electronic atomization device 401 is controlled to be powered off; the second liquid leakage detection is carried out on the atomizer 405 through the first sensor 406 and the processor 403 in the suction state, and the electronic atomization device 401 is controlled to be powered off when the liquid leakage of the atomizer 405 is detected, so that the safety problems of smoking of smoke liquid, battery short circuit, self-discharge increase and explosion caused by failure of a battery charging function due to liquid leakage can be avoided, and the safety and the service life of the electronic atomization device 401 can be improved; and meanwhile, different leakage detection is carried out in the suction state and the standby state, so that the accuracy of leakage monitoring can be improved.
The present application further proposes an electronic atomization device of a third embodiment, as shown in fig. 8, an electronic atomization device 801 of this embodiment includes a control assembly 802, a power assembly 803, an atomizer 804, and a cartridge 805. The power supply component 803 supplies power to the control component 802 and the atomizer 804, and the control component 802 controls the atomizer 804 to heat and atomize the cartridge 805.
As shown in fig. 9, the control assembly 802 of the present embodiment includes a first sensor 901 and a circuit board 902. The circuit board 902 integrates a processor (not shown), and the first sensor 901 is disposed on the circuit board 902 and electrically connected to the processor through a circuit on the circuit board 902.
Further, the electronic atomization device 801 of the embodiment further includes a second sensor 903, and the second sensor 903 is disposed on the circuit board 902 and electrically connected to the processor through a line on the circuit board 902.
After the processor controls the power supply component 803 to be turned on, that is, after the electronic atomization device 801 is powered on, the liquid leakage monitoring method of the above embodiment may be used to perform liquid leakage monitoring, so as to reduce the safety problem caused by liquid leakage, and improve the safety and the service life of the electronic atomization device 801.
