The atomizer is provided with a liquid storage cavity for storing atomizing media. The atomizing medium is heated by the atomizing assembly to form an aerosol.
If the atomizing assembly continues to heat after the atomizing medium is exhausted, the atomizing assembly may overheat in the electronic atomizing device due to dry burning and produce a scorched smell. Because traditional electron atomizing device can't in time stop atomizing subassembly heating when atomizing medium is spent, bring bad user experience.

According to the atomization treatment method, when a user sucks aerosol, air flow is formed in the air suction channel, and the electronic atomization device is triggered to start to work by the flow of the air flow. The aerosol formed by the atomization medium heated by the electronic atomization device enters the mouth of the user along with the airflow in the air suction channel. Each time an aerosol is drawn, a single time consumption is formed that is sustained by each drawing process. And when each time of forming the single consumed time, all formed single consumed times are overlapped to obtain an accumulated value. When the accumulated value is larger than the safety time threshold, the heating power of the electronic atomization device is lower or zero by limiting the power output to the electronic atomization device, so that the electronic atomization device is prevented from dry burning after the atomization medium is exhausted, and the user is prevented from inhaling the scorched smell gas. Because the actual absorption resistance value in the air suction channel is smaller, the consumption speed of the atomization medium in unit time is faster, and when the actual absorption resistance value is larger, the consumption speed of the atomization medium in unit time is slower.

In one embodiment, in compensating the single time consumption, the single time consumption is adjusted in a decreasing manner when the actual suction resistance is greater than the average suction resistance, and the single time consumption is adjusted in an increasing manner when the actual suction resistance is less than the average suction resistance.
In one embodiment, in detecting the actual suction resistance value, detecting the actual suction resistance value for at least one of a plurality of times of suction started by the electronic atomization device, and forming a reference suction resistance value; after the first several puffs, each puff adjusts the single elapsed time according to the reference resistance to draw value.
In one embodiment, in detecting the actual suction resistance value, detecting the actual suction resistance value for at least one of a plurality of times of suction started by the electronic atomization device, and forming a reference suction resistance value; after the first several puffs, the safety time threshold is adjusted according to the reference resistance to aspiration.
In one embodiment, in adjusting the safety time threshold, the safety time threshold is adjusted to increase when the reference resistance is greater than an average resistance, and the safety time threshold is adjusted to decrease when the reference resistance is less than the average resistance.
In one embodiment, the input voltage of the atomizing assembly in the electronic atomizing device is controlled by the electronic switching device in the single elapsed time, which is the difference obtained by subtracting the voltage rise time of the electronic switching device from the flow duration of the suction air stream, respectively, forming each suction.
In one embodiment, in detecting the duration of each puff of the aerosol, the timing of the flow duration of the puff is started in accordance with the change in air pressure in the inhalation channel.
In one embodiment, the change in air pressure in the suction channel is detected by an air flow sensor.
In one embodiment, the calculation of the accumulated value is triggered after each acquisition of one of the single elapsed times, respectively, forming the single elapsed time for each puff.

In one embodiment, in limiting the power output to the electronic atomizing device, an electronic switching device remains off the current path of the atomizing assembly in the electronic atomizing device.
An electronic atomizing device is used for implementing an atomizing treatment method.

In other embodiments, the electronic nebulizing device 100 may be a drug solution nebulizer, and the nebulizing medium is nebulizable drug solution.
Further, as shown in fig. 1, the atomizing assembly 30 includes a liquid guiding member 31 and a heat generating member 32 connected to a wall surface of the liquid guiding member 31, and more specifically, the liquid guiding member 31 may be a porous ceramic body or other material capable of absorbing and guiding the flow of the atomizing medium. The heat generating element 32 can generate heat when current passes through it, thereby generating a heating effect. More specifically, the heat generating member 32 may be a heat generating resistive wire disposed on the wall surface of the porous ceramic body.
Further, the switch control member is an electronic switch device, and the electronic switch device is disposed between the power output module and the heating member 32, and is used for controlling the on-off of the current of the heating member 32. Specifically, the electronic switching device is a power electronic device, such as a MOS transistor or other electronic devices capable of transmitting voltage and realizing on-off control.
Further, the power output module at least comprises an energy storage element, and the energy storage element comprises a battery cell or other components capable of realizing energy storage. The power output module may further include a power conditioner that adjusts the magnitude of the output current or the output voltage. Specifically, the energy storage member may be detachably connected to the liquid storage member 20, and the atomizing assembly 30, the airflow sensor and the switch control member may be connected to the liquid storage member 20.

More specifically, the control module is an MCU. The electronic atomizing apparatus 100 further includes an operation indicator, and when the power output module outputs a voltage to the heat generating member 32 through the electronic switching device, the control module causes the operation indicator to pass a current and generate an operation indication light or a warning sound. More specifically, the operation indicator is an LED light or other device capable of producing a light or audible cue.
Referring to fig. 2, the present invention provides an atomization method, which includes the following steps:
s10: presetting a safe time threshold T for sucking aerosol based on different suction resistance values;
s20: detecting the duration of each puff of aerosol, forming a single time consumption t for each puff x ；
S30: at all single time spent t x Accumulated value t of (2) z When greater than or equal to the safe time threshold T, the power output of the electronic atomizing device 100 is limited.
When a user draws in aerosol, an air flow is formed in the inhalation passage 22, and the flow of the air flow triggers the electronic atomizing device 100 to start operation. Aerosol formed by the heating of the atomizing medium by the electronic atomizing device 100 enters the user's mouth with the air flow in the air suction passage 22. At each puff of aerosol, a single consumption time t is formed which is sustained by each puff x . At each timeForm a single time of consumption t x At the time, all formed single times are consumed for time t x Superposing to obtain an accumulated value t z . When the accumulated value t z When the power output of the electronic atomization device 100 is limited when the power output of the electronic atomization device 100 is larger than the safe time threshold T, the heating power of the electronic atomization device 100 is lower or zero, so that dry burning of the electronic atomization device 100 after an atomization medium is exhausted is avoided, and a user is prevented from inhaling the scorched smell gas. Because the actual absorption resistance value in the air suction channel 22 is smaller, the consumption speed of the atomized medium in unit time is faster, and when the actual absorption resistance value is larger, the consumption speed of the atomized medium in unit time is slower, and the safe time threshold T is set according to the consumption time of the atomized medium with a preset volume under different absorption resistance values, so that the large difference of absorption resistance values between the actual product and the test product of the electronic atomization device 100 is avoided, the safe time threshold T can more accurately correspond to the consumption condition of the atomized medium in the actual product, and the dry burning of the electronic atomization device 100 is avoided and the waste of the atomized medium is reduced.
Further, as shown in fig. 3, the atomization treatment method further includes the following steps:
s40: according to the actual suction resistance value, the single consumption time t is compensated x And/or adjusting the safety time threshold T.
Specifically, the actual suction resistance value in the suction flow path is detected by the MEMS sensor in the present embodiment.
By detecting the actual suction resistance value in the suction channel 22 when the user sucks the aerosol, the single consumption time t is compensated according to the actual suction resistance value of the actual product of the electronic atomizing device 100 when in use x Or the safe time threshold T is adjusted, so that the limitation on the atomized medium can be more accurate, and the phenomenon that the atomized medium is exhausted before the power output is limited or more atomized medium remains after the power output is limited is avoided.
The general habits of a user using the electronic atomizing device 100 are: the user's mouth contains a mouthpiece end 21 and then draws aerosol through the mouthpiece end 21. After the user inhales a volume of aerosol, the user's mouth leaves the mouthpiece end 21, drawing in the aerosolAnd (3) ending the process, and then discharging the aerosol in the suction inlet by the user. Single time of consumption t x To consume the duration of the nebulized medium during a single puff of aerosol.
Before considering the different values of the resistance to suction, the safety time threshold T is referenced to the average time of use T of a predetermined volume of nebulized medium p1 And (5) setting. More specifically, to obtain the average use time t p1 The first electronic atomizing device without injecting the atomizing medium and the second electronic atomizing device with injecting the atomizing medium with preset volume can be selected, and the weight K of the first electronic atomizing device is weighed 10 . Then, the second electronic atomizing device is circulated between the suction use state and the suspension use state until the weight K of the second electronic atomizing device 2 Close to the weight K of the first electronic atomizing device 10 Recording the number of cycles P of the suction use state 1 . Further, the cycle number of the suction use states of the other (N-1) second electronic atomization devices is recorded, and the cycle number is sequentially P 2 、P 3 、…、P N . When the duration period of each suction use state is fixed to t 1 At the time, an average use time t p1 ＝t 1 ·(P 1 +P 2 + 3 +…+P N )/N。
For step S10, at average use time t p1 On the basis of the above, in order to consider the influence of different suction resistance values on the consumption speed of the atomized medium, a plurality of set suction resistance values can be selected in the range of values where the actual suction resistance values possibly appear, after the suction resistance value of a group of test articles containing N second electronic atomization devices is set as the first set suction resistance value, the second electronic atomization devices of the group are circulated between a suction use state and a suspension use state until the weight K of the second electronic atomization devices 2 Close to the weight K of the first electronic atomizing device 10 Obtaining an average value t of the suction time of the N second electronic atomization devices under the first set suction resistance value p11 . After the suction resistance value of another group of test articles of the electronic atomizing device 100 is set to be the second set suction resistance value, the group of second electronic atomizing devices are in the suction use state and the suspension use stateThe atomized medium is consumed by intermittent circulation, and the average value t of the suction time of N second electronic atomization devices under the second set suction resistance value is obtained p12 . After a plurality of groups of test articles with N second electronic atomization devices are respectively tested, average use time t under different set suction resistance values is sequentially obtained p11 、t p12 、…、t p1N . At average suction resistance, the average service time of the predetermined volume of atomized medium is t p2 ＝(t p11 +t p12 +t p13 …+t p1N ) N. The average suction resistance value may be an average value of a plurality of set suction resistance values. Specifically, the safe time threshold T may be directly preset as the average use time T p2 Can also be used for the average service time t p2 Is adjusted appropriately on the basis of (a).
Further, the set suction resistance values are incrementally arranged in an arithmetic progression, so that the set suction resistance values can reflect the suction resistance of the electronic atomization device 100 in different working states.
Further, the preset upper limit of the safety time threshold T is 95-97% of the exhaustion time of the atomized medium under the preset suction resistance. Because the atomized media in the actual product of the electronic atomizing device 100 may volatilize, leak or solidify to the cavity wall in the long-time storage or transportation process, the actual usable amount of the atomized media is reduced, and by properly reducing the safety time threshold T, the atomized media can be prevented from being completely consumed by the user, the electronic atomizing device 100 is prevented from being burned dry, and the waste of the atomized media can be reduced as much as possible. Specifically, the predetermined suction resistance may be an average value of a plurality of set suction resistance values.
For step S20, as shown in connection with fig. 3, in some embodiments, in detecting the duration of each inhalation of aerosol, the flow-through duration t of the inhalation airflow is initiated in accordance with the change in air pressure within the inhalation channel 22 c As shown in step S21. Recognition of the user's suction operation by the variation of the air pressure in the suction channel 22, enabling the circulation duration t c Reflects the use time of the user and the circulation duration t c Can reflect atomized medium to a certain extentConsumption amount. More specifically, when the user pumps the aerosol, an air flow having a large flow rate is generated in the inhalation passage 22, and the air pressure in the inhalation passage 22 will drop according to the bernoulli principle. When the user stops sucking the aerosol, the air flow in the air suction passage 22 stops, and the air pressure in the air suction passage 22 increases. Therefore, it is possible to confirm that the user is performing the suction operation based on the air pressure in the air suction passage 22. Specifically, the change in air pressure within the air suction passage 22 may be identified by the air flow sensor, thereby identifying that the user is using the electronic atomizing apparatus 100. In this embodiment, the air flow sensor may be a microphone or MEMS sensor.
In some embodiments, the single time of consumption t is established for each puff separately x In a single time of consumption t x For the duration t of the suction flow c Subtracting the voltage rise time t of the electronic switching device s The difference obtained later.
Specifically, since the atomizing assembly 30 is configured to atomize the atomizing medium after the temperature of the heat generating component 32 increases to a predetermined value, the passing current of the heat generating component 32 is required to reach the rated value. When the air flow sensor detects that the suction air flow passes through, the electronic switching device is triggered to be switched to the communication state, so that the electronic switching device can be switched to the working state in time. However, due to the characteristics of the electronic switching device, a certain transition time is required for switching from the off state to the on state, and it is understood that the transition time is a voltage rise time for the output voltage of the electronic switching device to rise to the target voltage. More specifically, the control module counts the flow duration t for each puff through feedback from the airflow sensor c In turn t c1 、t c2 、…、t cn Etc. The control module will circulate for a duration t c Subtracting the voltage rise time t of the electronic switching device s Obtaining single consumption time t of each suction x In turn t x1 、t x2 、…、t xn . Single time of consumption t x Eliminating the voltage rise time t of the electronic switching device s And thus accurately reflect the consumption of the nebulized medium.
In some embodiments, as shown in connection with FIG. 3, a single time of consumption t is created for each puff separately x In (2) each time a single time t is obtained x After that, the accumulated value t is triggered z As shown in step S22. Specifically, after the duration of each puff of aerosol has ended, a single time t is consumed x And the timing synchronization of (c) is ended. Thereafter, the single time t is consumed just after acquisition x And accumulated value t z Adding the historical values of the three values to obtain a new accumulated value t z Thus, after each evacuation of the sol, the value t is accumulated z A corresponding increase is produced.
In other embodiments, it is also possible that the flow-through duration t of each puff is c Directly as a single time of consumption t x 。
In some embodiments, in limiting the power output to the electronic atomizing apparatus 100, the electronic switching device remains off the current path of the atomizing assembly 30, and more specifically, the heat generating component 32. Further, after limiting the power output to the atomizing assembly 30, the control module stops operation of all of the operation indicators, or stops triggering between the airflow sensor and the electronic switching device. Further, after limiting the power output to the atomizing assembly 30, the power regulation charging function to the energy storage element is limited by the control module. Further, the operation indicator stops operating in limiting the power output to the electronic atomizing device 100.
Further, the magnitude of the safety time threshold T may be adjusted according to the volume change of the nebulized medium.
Specifically, due to the accumulated value t z According to a single time consumption t x The magnitude of (2) changes discretely rather than continuously, and is therefore typically the accumulated value T after the last puff, which is originally less than the safe time threshold T z Superimposing the last single elapsed time t x And then greater than the safe time threshold T, thereby triggering a limitation of the power output. More specifically, it may also be an accumulated value t z Superimposing the last single elapsed time t x Thereafter, a limitation of the power output is triggered when the safety time threshold T is equal.
For step S40, in some embodiments, as shown in fig. 4, due to the structural characteristics of the electronic atomizing device 100 or the usage habits of different users, the actual inhalation resistance value of each inhalation of the same electronic atomizing device 100 is greatly changed, the airflow sensor detects the actual inhalation resistance value of each inhalation aerosol, as shown in step S41, and the single consumption time t of each inhalation is based on the currently detected actual inhalation resistance value x Compensation for different proportions or different differences is made. In another embodiment, the adjustment of the safety time threshold T may be continuously made in different proportions or different differences according to the actual suction resistance value detected at the present time.
Further, as shown in fig. 4, a plurality of different absorption resistance sections may be divided for the range of values where the actual absorption resistance value may occur, and in step S42, the absorption resistance sections may be adjacent in value and not overlap with each other. More specifically, the width of each suction resistance section may be uniform. When the actual suction resistance value is obtained through detection each time, determining the suction resistance interval where the actual suction resistance value is located according to the size of the actual suction resistance value. In some embodiments, the electronic atomizing device 100 has a draw resistance ranging from 0.1Kpa to 2Kpa. In one embodiment, the electronic atomization device 100 has a suction resistance range of 0.35Kpa to 0.6Kpa, and may be divided into a plurality of suction resistance sections such as a suction resistance section 1, a suction resistance section 2, and a suction resistance section …, and a suction resistance section N.
In some embodiments, as shown in connection with fig. 4, the electronic atomizing device 100 stores the sustainable time T under different suction resistance intervals S As shown in table 1, under the assumption that the actual suction resistance value of the electronic atomizing device 100 is always maintained in one suction resistance region, the duration T of the suction resistance region S Equal to all single elapsed time t x Final accumulated value t z 。
Table 1:
in some embodiments, in adjusting the safety time threshold T, the accumulated time T of each suction resistance interval is used q For accumulated value t z The duty cycle r of (c) and the safety time threshold T. The actual absorption resistance value is basically consistent in the process of sucking aerosol once, but under the condition that the absorption resistance values of the aerosol sucked for each time are possibly different, the accumulated time t of one absorption resistance interval is after the aerosol is sucked for each time q Increase the single consumption time t for the last suction just ended x . As shown in the following table, the accumulation time t of each section q And accumulated value t z And a corresponding duty cycle r is formed therebetween. The safe time threshold T is adjusted according to the duty ratio r of different suction resistance intervals by combining the step (1), so that the safe time threshold T can be combined with the dynamic change of the actual suction resistance value, the consumption speed of the atomized medium under different actual suction resistance values can be reflected more accurately, the dry burning is avoided, and the waste of the atomized medium is reduced.
T＝r 1 ·T S1 +r 2 ·T S2 +…+r n ·T Sn (1)
Further, since each suction resistance section has a left boundary and a right boundary, that is, a minimum value and a maximum value of the suction resistance section, an actual suction resistance value of the right boundary is greater than an actual suction resistance value of the left boundary. At smaller actual values of the resistance to absorption, a shorter safety time threshold T needs to be set, since the flow rate of the aerosol is greater, resulting in an increased consumption of the nebulized medium. In the present embodiment, the sustainable time of the suction section is set according to the actual suction resistance value of the left boundary, specifically, the suction resistance value of the test article of the plurality of second electronic atomizing devices may be set as the actual suction resistance value of the left boundary of the suction resistance section, and then the average value of the suction times of the plurality of second electronic atomizing devices may be taken as the sustainable time of the suction section. Because the actual product of the electronic atomization device 100 generally has a randomly-occurring suction resistance value within the suction resistance interval, and is not concentrated to the actual suction resistance value of the left boundary, the atomization medium can be prevented from being exhausted before reaching the sustainable time, and the electronic atomization device 100 is prevented from being dry-burned.
Further, in order to improve the accuracy of dry combustion control, the width of the suction resistance interval can be reduced, and the dividing number of the suction resistance interval is increased, so that the actual suction resistance value range during each suction can be more accurately determined in the suction resistance interval, and the adjustment of the safety time threshold T is more accurate.
In some embodiments, as shown in FIG. 5, if the different suction resistance sections are not divided, the single consumption time t is compensated x When the actual suction resistance is detected according to each aerosol suction process, the time t is consumed once when the actual suction resistance is larger than the difference value of the average suction resistance x Make a reduction adjustment, when the actual suction resistance is smaller than the difference value of the average suction resistance, the single consumption time t x An increase adjustment is made as by step S43. Specifically, after the end of each aerosol sucking process, the method can be used for combining a single consumption time t according to the difference between the detected actual suction resistance value and the average suction resistance value x Calculating to obtain a second adjustment value, an accumulated value t z And superposing the second adjustment value. More specifically, the second adjustment value may be a negative value when the actual suction resistance value is greater than the average suction resistance value, and may be a positive value when the actual suction resistance value is less than the average suction resistance value.
Specifically, when the time t is consumed once by compensation x After eliminating the influence of the actual suction resistance value not equal to the average suction resistance value, the single consumption time t after compensation adjustment is carried out x To accumulate to obtain an accumulated value t z Thereby making the accumulated value t z The represented consumption time of the atomized medium can reflect the consumption amount of the atomized medium more accurately.
In other embodiments, if the different suction resistance sections are not divided, in adjusting the safety time threshold T, the safety time threshold T is adjusted to be increased when the actual suction resistance value is greater than the average suction resistance value, and the safety time threshold T is adjusted to be decreased when the actual suction resistance value is less than the average suction resistance value, as in step S44. In particular, it is possible toSo that after the end of each aerosol sucking process, the method combines the single consumed time t according to the difference between the detected actual suction resistance value and the average suction resistance value x And the first adjustment value is obtained through calculation, and the safety time threshold T is overlapped with the first adjustment value. More specifically, the first adjustment value may be a positive value when the actual suction resistance value is greater than the average suction resistance value, and may be a negative value when the actual suction resistance value is less than the average suction resistance value.
In other embodiments, as shown in fig. 6, in the detection of the actual suction resistance value of some embodiments, the actual suction resistance value of each suction of the same electronic atomization device 100 remains substantially unchanged, and the actual suction resistance value may be detected for at least one of several suction operations in which the electronic atomization device 100 is started to be used, and a reference suction resistance value is formed, and after the first several suction operations, the single consumption time t is adjusted for each suction operation according to the reference suction resistance value x As by step S45.
In other embodiments, as shown in connection with fig. 7, the safe time threshold T may be adjusted according to the reference suction resistance value after the first several puffs, as by step S45. Specifically, when the reference resistance is greater than the average resistance, the safety time threshold T is adjusted to be increased, and when the reference resistance is less than the average resistance, the safety time threshold T is adjusted to be decreased, as in step S46.
Specifically, in one embodiment, the actual suction resistance value in the suction channel 22 is detected only when the electronic atomizing device 100 is used for the first time, and then the actual suction resistance value of the default electronic atomizing device 100 is kept unchanged as the reference suction resistance value, and each single time consumption time t is compensated according to the reference suction resistance value x Or make a fixed ratio or fixed difference adjustment to the safe time threshold T at a time.
In another embodiment, the electronic atomizing device 100 may detect the actual suction resistance value of more than one suction in the first several suction, calculate the average of the detected actual suction resistance values to form a reference suction resistance value, and compensate each single consumption time t according to the reference suction resistance value x Or at a timeThe security time threshold T is sexually adjusted.
