The electronic atomization device mainly comprises an atomizer and a power supply assembly. The atomizer generally includes a liquid storage component and an atomizing component. The atomizer is provided with a liquid storage cavity for storing an atomized medium. The atomization medium is heated by the atomization assembly to form an aerosol.
After the atomizing medium is exhausted, if the atomizing assembly continues to be heated, the atomizing assembly may overheat and generate scorched smell in the electronic atomizing device due to dry burning. Because traditional electron atomizing device can't in time stop atomizing component heating when atomizing medium exhausts, bring not good user experience.

According to the atomization treatment method, when a user sucks aerosol, airflow is formed in the air suction channel, and the flow of the airflow triggers the electronic atomization device to start working. The aerosol formed by the heating action of the electronic atomization device enters the mouth of the user along with the airflow in the air suction channel. At each puff of the aerosol, a single elapsed time is created for each puff. Every time the single elapsed time is formed, all the single elapsed times that have been formed are superimposed to obtain an accumulated value.

Because the actual resistance value of inhaling in the passageway is less, the consumption speed of atomizing medium in unit interval is very fast, when the actual resistance value of inhaling is great, the consumption speed of atomizing medium in unit interval is very slow, this scheme sets for safe time threshold according to the consumption time of predetermined volume atomizing medium under the different resistance values of inhaling, avoid having great resistance value difference between the actual product of electron atomizing device and the experimental product, let safe time threshold can correspond the atomizing medium consumption condition in the actual product more accurately, avoid electron atomizing device's dry combustion method and reduce the waste of atomizing medium.

In one embodiment, in compensating for the single consumption time, the single consumption time is adjusted to be decreased when the actual resistance value is greater than the average resistance value, and the single consumption time is adjusted to be increased when the actual resistance value is less than the average resistance value.
In one embodiment, in the step of detecting the actual resistance value, the actual resistance value is detected for at least one of a plurality of times of suction started by the electronic atomization device, and a reference resistance value is formed; after a number of puffs have been initiated, each puff adjusts the single elapsed time according to the reference puff value.

In one embodiment, in the adjusting of the safe time threshold, when the reference resistance value is greater than the average resistance value, the safe time threshold is increased, and when the reference resistance value is less than the average resistance value, the safe time threshold is decreased.
In one embodiment, the input voltage of the atomizing assembly in the electronic atomizer is controlled by an electronic switching device during the single consumption time for respectively forming each suction, wherein the single consumption time is the difference obtained by subtracting the voltage rise time of the electronic switching device from the circulation duration time of the suction airflow.

In some embodiments, the electronic atomization device 100 can be an electronic cigarette, and the atomization medium is a liquid. In other embodiments, the electronic aerosolization device 100 can be a liquid drug aerosolizer and the aerosolization medium is an aerosolizable liquid drug.
Further, referring to 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 materials capable of absorbing and guiding the flow of the atomizing medium. The heat generating member 32 generates heat when an electric current is applied thereto, thereby generating a heating action. More specifically, the heating member 32 may be a heating resistance 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 heat generating member 32, and is used for controlling on/off of current of the heat generating member 32. Specifically, the electronic switching device is a power electronic device, such as a MOS transistor or other electronic device capable of transmitting voltage and implementing on-off control.

More specifically, the operation indicator is an LED lamp or other device capable of generating a light or sound prompting effect.
Referring to fig. 2, the present invention provides an atomization processing method, which includes the following steps:
s10: presetting a safety time threshold T for sucking the aerosol based on different values of the resistance;
s20: detecting the duration of each puff of the aerosol, respectively forming a single elapsed time t for each puffx；
S30: at all single elapsed times txAccumulated value t ofzAnd when the safety time threshold value T is greater than or equal to the safety time threshold value T, limiting the power output of the electronic atomization device 100.
When the user sucks the aerosol, an airflow is formed in the air suction passage 22, and the flow of the airflow triggers the electronic atomization device 100 to start working. The aerosol formed by the heating of the aerosol medium by the electronic atomization device 100 enters the user's mouth with the airflow in the inhalation passage 22. At each puff of the aerosol, a single elapsed time t is formed for each puffx. At a single elapsed time t per formationxAll the single elapsed times t that have been formed are addedxOverlapping to obtain an accumulated value tz. When the accumulated value t iszWhen the safety time threshold T is greater than the safety time threshold T, the power output to the electronic atomization device 100 is limited, so that the heating power of the electronic atomization device 100 is low or zero, dry burning of the electronic atomization device 100 after the atomization medium is exhausted is avoided, and the user is prevented from inhaling the burnt gas. Because the actual resistance of inhaling in the passageway 22 is less, the consumption speed of atomizing medium in unit time is faster, and when the actual resistance of inhaling is great, the consumption speed of atomizing medium in unit time is slower, and this scheme sets for safe time threshold T according to the consumption time of predetermined volume atomizing medium under the different resistance of inhaling value, avoids having great resistance of inhaling difference between the actual product of electron atomizing device 100 and the experimental product, lets safe time threshold T can correspond the atomizing medium consumption condition in the actual product more accurately, avoids the dry combustion of electron atomizing device 100 and reduces the waste of atomizing medium.
Further, as shown in fig. 3, the atomization processing method further includes the following steps:
s40: according to the actual resistance value, compensating the single time consumption txAnd/or adjusting the safety time threshold T。
Specifically, in the present embodiment, the actual suction resistance value in the suction flow channel is detected by the MEMS sensor.
By detecting the actual inhalation resistance value in the inhalation passage 22 when the user inhales the aerosol, the single elapsed time t is compensated for according to the actual inhalation resistance value of the actual product of the electronic atomization device 100 in usexOr the safety time threshold T is adjusted, so that the limit on the atomized medium can be more accurate, and the situation that the atomized medium is exhausted before the power output is limited or more atomized medium still remains after the power output is limited is avoided.
The general habits of users using the electronic atomization device 100 are: the user's mouth, having a mouth end 21, draws aerosol through the mouth end 21. After the user inhales a certain volume of aerosol, the mouth of the user leaves the mouthpiece end 21, the process of drawing the aerosol is finished, and the user spits out the aerosol in the mouthpiece again. Single elapsed time txThe duration of the nebulized medium is consumed for a single puff of the aerosol.
The safety time threshold T is referenced to the average time of use T of a predetermined volume of nebulized medium before taking into account the different values of the resistance of the inhalationp1And (4) setting. More specifically, to obtain the average time of use tp1The first electronic atomization device without the atomization medium and the second electronic atomization device with the atomization medium with the preset volume can be selected, and the weight K of the first electronic atomization device is weighed10. Then, the second electronic atomization device is cycled between the suction use state and the pause use state until the weight K of the second electronic atomization device2Weight K close to the first electronic atomizer10Recording the number of cycles P of the suction application state1. Further, the cycle times of the pumping use states of the other (N-1) second electronic atomization devices are recorded and are sequentially P2、P3、…、PN. When the duration period of each suction use state is fixed to t1Then, the average service time t is obtainedp1＝t1·(P1+P2+3+…+PN)/N。
For step S10, at average time of use tp1On the basis, for considering 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 numerical range where the actual suction resistance value is likely to appear, and after the suction resistance value of a group of test articles containing N second electronic atomization devices is set as a first set suction resistance value, the second electronic atomization devices of the group are circulated between the suction use state and the pause use state until the weight K of the second electronic atomization devices2Weight K close to the first electronic atomizer10Obtaining the average value t of the suction time of the N second electronic atomization devices under the first set suction resistance valuep11. After the suction resistance value of the other group of the electronic atomization devices 100 is set as a second set suction resistance value, the group of the second electronic atomization devices is circulated between the suction use state and the pause use state to consume the atomization medium, and the average value t of the suction time of the N second electronic atomization devices under the second set suction resistance value is obtainedp12. After a plurality of groups of test products with each group of N second electronic atomization devices are respectively tested, the average service time t under different set suction resistance values is sequentially obtainedp11、tp12、…、tp1N. The average time of use of a predetermined volume of the atomized medium at the average resistance to draw is tp2＝(tp11+tp12+tp13…+tp1N) and/N. The average suction resistance value can be an average value of a plurality of set suction resistance values. In particular, the safety time threshold T can be directly preset as the average time of use Tp2Or at the average use time tp2And then appropriately adjusted on the basis.
Furthermore, the set resistance values are arranged in an arithmetic progression manner, so that the set resistance values can reflect the 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 atomization medium in the actual product of the electronic atomization device 100 may volatilize, leak, or solidify to the cavity wall in the process of long-time storage or transportation, and the like, the actual usable amount of the atomization medium decreases, and by properly reducing the safety time threshold T, the user can be prevented from completely exhausting the atomization medium, the electronic atomization device 100 is prevented from being burned dry, and the waste of the atomization medium can be reduced as much as possible. Specifically, the predetermined resistance to draw may be an average of a number of set resistance to draw values.
For step S20, shown in connection with fig. 3, in some embodiments, in detecting the duration of each puff of aerosol, the duration t of the puff starts to draw the flow according to the pressure change in the inhalation passage 22cAs shown in step S21. The suction operation of the user is identified by the change in the air pressure in the suction channel 22, thus allowing a circulation duration tcReflecting the user's duration of use and the circulation duration tcThe consumption of the atomized medium can be reflected to a certain extent. More specifically, when the user draws an 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 decrease according to the bernoulli principle. When the user stops drawing the aerosol, the air flow movement in the inhalation passage 22 stops and the air pressure in the inhalation passage 22 will rise. Therefore, it can be confirmed that the user is performing the suction operation according to the air pressure in the suction passage 22. Specifically, a change in air pressure within the inhalation passage 22 can be identified by the air flow sensor, thereby identifying that the user is using the electronic atomization device 100. In this embodiment, the airflow sensor may be a microphone or a MEMS sensor.
In some embodiments, each puff is formed at a single elapsed time txIn, single time of consumption txFor the duration t of circulation of the suction air flowcMinus the rise time t of the voltage of the electronic switching devicesThe difference obtained after this.
Specifically, since the atomizing assembly 30 can atomize the atomizing medium only after the temperature of the heat generating member 32 rises to a predetermined value, the passing current of the heat generating member 32 needs to reach a rated value. When the air flow sensor detects the passage of the sucked air flow, the electronic switch device is triggered to be switched to a connected state, so that the electronic switch device can be switched in timeStatus. 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 understandably, the transition time is a voltage rise time during which the output voltage of the electronic switching device rises to the target voltage. More specifically, the control module times the flow duration t for each puff via feedback from the airflow sensorcIn order of tc1、tc2、…、tcnAnd the like. The control module will circulate for a duration tcMinus the rise time t of the voltage of the electronic switching devicesObtaining the single consumption time t of each suctionxIn order of tx1、tx2、…、txn. Single elapsed time txThe voltage rise time t of the electronic switching device is eliminatedsThus accurately reflecting the consumption of the atomized medium.
In some embodiments, as shown in connection with fig. 3, at a single elapsed time t, where each puff is separately formedxIn each acquisition of a single elapsed time txThen, trigger the accumulated value tzAs shown in step S22. In particular, a single consumption time t after the end of the duration of each puff of aerosolxThe timing synchronization of (2) ends. Thereafter, the single elapsed time t just acquiredxAnd the accumulated value tzIs added to obtain a new accumulated value tzTherefore, after each evacuation of the sol, the value t is accumulatedzA corresponding increase is produced.
In other embodiments, it is also possible to have a circulation duration t of each suctioncDirectly as a single elapsed time tx。
In some embodiments, in limiting the power output to the electronic atomization device 100, the electronic switching device remains off the current path of the atomization assembly 30, and more particularly, the heat generating member 32. Further, after limiting power output to the atomizing assembly 30, the control module stops operation of all the operation indicators or stops the triggering action between the airflow sensor and the electronic switching device. Further, after limiting the power output to the atomizing assembly 30, the function of charging the energy storage member by the power regulation is limited by the control module. Further, in limiting the power output to the electronic atomization device 100, the operation indicator stops operating.
Further, the magnitude of the safety time threshold T may be adjusted according to the volume change of the nebulized medium.
In particular, due to the accumulated value tzIs based on a single elapsed time txIs in discrete transition, rather than continuous, so that the accumulated value T, which is originally smaller than the safety time threshold T after the last suction, is generallyzThe last time of the superposition single time of consumption txAnd then greater than the safe time threshold T, thereby triggering a limit on power output. More specifically, it may be the accumulated value tzThe last time of the superposition single time of consumption txThen, a limit of the power output is triggered at a time equal to the safety time threshold T.
For step S40, in some embodiments, in combination with fig. 4, due to the structural characteristics of the electronic atomization device 100 or the usage habits of different users, the actual resistance to draw per time of the same electronic atomization device 100 varies greatly, the airflow sensor detects the actual resistance to draw per time of the aerosol as step S41, and the single elapsed time t of each draw is determined according to the currently detected actual resistance to draw per time txCompensation for different proportions or different differences is made. In another embodiment, the safe time threshold T may be continuously adjusted in different proportions or different differences according to the actual resistance value detected this time.
Further, referring to fig. 4, a plurality of different resistance suction intervals may be divided according to a possible numerical range of the actual resistance suction value, as shown in step S42, and the resistance suction intervals may be adjacent in value and do not overlap with each other. More specifically, the widths of the respective suction resistance sections may be uniform. And when the actual resistance value is detected and obtained every time, determining the resistance suction interval in which the actual resistance value is positioned according to the actual resistance value. In some embodiments, the electronic atomization device 100 has a resistance to draw in a range from 0.1Kpa to 2 Kpa. In one embodiment, the suction resistance range of the electronic atomization device 100 is 0.35Kpa to 0.6Kpa, and the suction resistance range of 0.35Kpa to 0.6Kpa may be divided into a suction resistance range 1, a suction resistance range 2, a suction resistance range N of …, and so on.
In some embodiments, as shown in fig. 4, the electronic atomizer 100 stores the sustainable time T for different suction resistance intervalsSAs shown in table 1, under the assumption that the actual resistance value of the electronic atomizer 100 during each suction is always maintained in one of the resistance suction intervals, the duration T of the resistance suction interval isSEqual to all single elapsed times txFinal accumulated value tz。
Table 1:
in some embodiments, in adjusting the safety time threshold T, the accumulated time T of each resistance suction interval is adjusted according toqFor accumulated value tzThe safety time threshold T is adjusted. The actual resistance values are basically consistent in the process of sucking the aerosol once, under the condition that the resistance values of the sucked aerosol are possibly different, after the aerosol is sucked every time, the accumulated time t of one resistance sucking interval isqIncreasing the single elapsed time t for the duration of an immediately completed puffx. The accumulated time t for each interval is shown in the table belowqAnd the accumulated value tzForming a corresponding ratio r. The combined type (1) adjusts the safe time threshold T according to the proportion r of different suction resistance intervals, 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, dry burning is avoided, and the waste of the atomized medium is reduced.
T＝r1·TS1+r2·TS2+…+rn·TSn (1)
Further, since each of the resistance-suction intervals has a left boundary and a right boundary, i.e., a minimum value and a maximum value of the resistance-suction interval, an actual resistance-suction value of the right boundary is greater than an actual resistance-suction value of the left boundary. At lower actual values of the draw resistance, a shorter safety time threshold T needs to be set, since the aerosol flow rate is higher, leading to an increased consumption of the nebulized medium. In the present embodiment, the sustainable time of the suction interval is set according to the actual suction resistance value of the left boundary, and specifically, the suction resistance value of the test pieces of the plurality of second electronic atomization devices may be set as the actual suction resistance value of the left boundary of the suction resistance interval, and then the average value of the suction times of the plurality of second electronic atomization devices may be used as the sustainable time of the suction interval. Because the resistance values of the actual products of the electronic atomization device 100 generally occur randomly within the resistance suction interval, and are not concentrated into the actual resistance values 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 burned dry.
Furthermore, in order to improve the accuracy of dry burning control, the width of the suction resistance interval can be reduced, and the dividing quantity of the suction resistance interval is increased, so that the range of the actual suction resistance value during each suction can be more accurately determined by the suction resistance interval, and the adjustment of the safe time threshold value T is more accurate.
In some embodiments, as shown in FIG. 5, if the different suction resistance intervals are not divided, the single consumption time t is compensatedxThe actual suction resistance value is detected according to the aerosol suction process each time, and when the actual suction resistance value is larger than the difference value of the average suction resistance value, the single time consumption time txMaking reduction adjustment, when the actual resistance value is less than the difference value of average resistance value, the single time consumption time txAn increase adjustment is made as in step S43. Specifically, the method may be combined with the single consumption time t after the end of each aerosol suction process according to the difference between the actual suction resistance value detected at the current time and the average suction resistance valuexAnd calculating to obtain a second adjustment value, the accumulated value tzAnd superposing the second adjustment value. More specifically, the second adjustment value may be negative when the actual resistance-to-draw value is greater than the average resistance-to-draw valueThe second adjustment value may be a positive value when the actual resistance value is less than the average resistance value.
In particular, when the time t is consumed once by compensatingxEliminating the influence of the actual resistance value not equal to the average resistance value, and adjusting the single time consumption t after compensationxAccumulating to obtain an accumulated value tzThereby making the accumulated value tzThe represented consumption time of the atomized medium reflects the consumption of the atomized medium more accurately.
In other embodiments, if the different resistance suction intervals are not divided, in adjusting the safe time threshold T, when the actual resistance suction value is greater than the average resistance suction value, the safe time threshold T is increased, and when the actual resistance suction value is less than the average resistance suction value, the safe time threshold T is decreased, as in step S44. Specifically, the method may be combined with the single consumption time t after the end of each aerosol suction process according to the difference between the actual suction resistance value detected at the current time and the average suction resistance valuexAnd calculating to obtain a first adjusting value, and superposing the first adjusting value by the safe time threshold T. More specifically, the first adjustment value may be a positive value when the actual resistance value is greater than the average resistance value, and may be a negative value when the actual resistance value is less than the average resistance value.
In other embodiments, referring to fig. 6, in the actual resistance value detection of some embodiments, the actual resistance value of each inhalation of the same electronic atomization device 100 is kept substantially unchanged, the actual resistance value of at least one of the several inhalations of which the electronic atomization device 100 starts to be put into use can be detected, and a reference resistance value is formed, and after the starting several inhalations, each inhalation adjusts the single consumption time t according to the reference resistance valuexAs by step S45.
In other embodiments, as shown in fig. 7, the safe time threshold T may be adjusted according to the reference resistance value after the first several puffs, as in step S45. Specifically, when the reference resistance value is larger than the average resistance value, the safe time threshold T is adjusted to be increased, and when the reference resistance value is smaller than the average resistance value, the safe time threshold T is adjusted to be decreased, as in step S46.
Specifically, in one embodiment, the actual resistance value in the air suction passage 22 is detected only when the electronic atomization device 100 is used for the first time, the actual resistance value of the electronic atomization device 100 is maintained as the reference resistance value by default, and each single elapsed time t is compensated according to the reference resistance valuexOr a fixed ratio or fixed difference adjustment may be made to the safe time threshold T at once.
In another embodiment, the electronic atomization device 100 may further detect an actual resistance value of more than one puff among the first puffs, average the detected actual resistance values to form a reference resistance value, and compensate each single elapsed time t according to the reference resistance valuexOr adjust the safe time threshold T once.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
