Description
Technical Field
The embodiment of the application relates to the technical field of electronic atomization, in particular to an electronic atomization device of an electronic atomization device, a power supply mechanism and an atomizer identification method.
Background
Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release compounds without burning.
Examples of such products are electrospray products, which produce an inhalable vapor or aerosol by heating a liquid substrate to vaporize it. The liquid matrix may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol). For such frequently used electronic atomization products, they are of modular construction and typically include a replaceable atomizer having a storage component for containing the liquid matrix. The liquid matrix stored in the nebulizer may vary significantly in composition, taste, concentration, or other characteristics, and the consumer may wish to interchange the nebulizers as desired. However, the optimum vaporization conditions may depend on the composition of the liquid matrix stored in the atomizer. It is therefore desirable to include in the nebulizer an automatic identification means which can identify the replaceable nebulizer or liquid matrix stored therein in order to automatically change the control settings of the vaporizing device accordingly.

To facilitate an understanding of the present application, the present application is described in more detail below with reference to the following figures and detailed description.
The present application provides an electronic atomizer, which can be seen in fig. 1, and includes an atomizer 100 storing a liquid substrate and vaporizing the liquid substrate to generate an aerosol, and a power supply mechanism 200 for supplying power to the atomizer 100.
In an alternative embodiment, such as shown in fig. 1, the power mechanism 200 includes a receiving chamber 270 disposed at one end along the length for receiving and housing at least a portion of the atomizer 100, and a first electrical contact 230 at least partially exposed at a surface of the receiving chamber 270 for making an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and housed in the power mechanism 200 to supply power to the atomizer 100.
According to the preferred embodiment shown in fig. 1, the atomizer 100 is provided with a second electrical contact 21 on the end opposite to the power supply mechanism 200 in the length direction, so that when at least a portion of the atomizer 100 is received in the receiving chamber 270, the second electrical contact 21 comes into contact against the first electrical contact 230 to thereby become electrically conductive.
The sealing member 260 is provided in the power supply mechanism 200, and the above receiving chamber 270 is formed by partitioning at least a part of the internal space of the power supply mechanism 200 by the sealing member 260. In the preferred embodiment shown in fig. 1, the sealing member 260 is configured to extend along the cross-sectional direction of the power supply mechanism 200, and is preferably made of a flexible material such as silicone to prevent the liquid medium seeping from the atomizer 100 to the receiving chamber 270 from flowing to the controller 220, the sensor 250, and the like inside the power supply mechanism 200.
In the preferred embodiment shown in fig. 1, the power supply mechanism 200 further includes a battery cell 210 for supplying power, which faces away from the receiving cavity 270 along the length direction; and a controller 220 disposed between the cell 210 and the housing cavity, the controller 220 operable to direct electrical current between the cell 210 and the first electrical contact 230.
The power supply mechanism 200 includes a sensor 250 for sensing a suction airflow generated when a user sucks on the nebulizer 100, and the controller 220 controls the battery cell 210 to output a current to the nebulizer 100 according to a detection signal of the sensor 250.
In a further preferred embodiment shown in fig. 1, the power supply mechanism 200 is provided with a charging interface 240 at the other end facing away from the receiving chamber 270, for charging the battery cells 210.
The embodiment of fig. 2 to 4 shows a schematic structural view of an embodiment of the atomizer 100 of fig. 1, which includes a main housing 10, a porous body 30, and a heating element 40:
as shown in fig. 2, the main housing 10 is substantially in the form of a flat cylinder, which is hollow inside, of course, for storing the atomized liquid medium and for housing other necessary functional components; the upper end of the main shell 10 is provided with a suction nozzle A for sucking aerosol;
the main shell 10 is internally provided with a liquid storage cavity 12 for storing liquid matrix; in specific implementation, a flue gas conveying pipe 11 arranged along the axial direction is arranged in the main shell 10, and a liquid storage cavity 12 for storing liquid matrix is formed in a space between the outer wall of the flue gas conveying pipe 11 and the inner wall of the main shell 10; the upper end of the smoke conveying pipe 11, which is opposite to the near end 110, is communicated with the suction nozzle opening A;
the porous body 30 is used for acquiring the liquid matrix in the liquid storage cavity 12 through the liquid passage 13, and the liquid matrix is transmitted as shown by an arrow R1 in FIG. 2; the porous body 30 has a planar atomising surface 310 and the atomising surface 310 has formed thereon a heating element 40 for heating at least part of the liquid substrate drawn up by the porous body 30 to generate an aerosol.
Referring specifically to fig. 3 and 4, the side of the porous body 30 facing away from the atomization surface 310 is in fluid communication with the liquid channel 13 to absorb the liquid matrix, which is then transferred to the atomization surface 310 for heated atomization.
Both ends of the heating element 40 are in abutment with the second electrical contact 21 after assembly and are thus electrically conductive, the heating element 40 heating at least part of the liquid substrate of the porous body 30 during energisation to generate an aerosol. In alternative implementations, the porous body 30 comprises flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or porous ceramics having a microporous structure, such as a porous ceramic body in the shape shown in fig. 3 and 4, the specific structure of which can be found in patent application CNCN 212590248U.
The heating element 40 may be bonded to the atomization surface 310 of the porous body 30 by printing, deposition, sintering, or physical assembly. In some other variations, the porous body 30 may have a flat or curved surface for supporting the heating element 40, and the heating element 40 is formed on the flat or curved surface of the porous body 30 by mounting, printing, depositing, or the like.
The material of the heating element 40 may be a metallic material, a metal alloy, graphite, carbon, a conductive ceramic or other ceramic material, and a composite of metallic materials with appropriate impedance. Suitable metal or alloy materials include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium-aluminum alloys, titanium alloys, iron-manganese-aluminum based alloys, stainless steel, or the like. The resistive material of the heating element 40 may be selected from a metal or alloy material having a suitable temperature coefficient of resistance, such as a positive temperature coefficient or a negative temperature coefficient, so that the heating circuit can be used to both generate heat and as a sensor for sensing the real-time temperature of the atomizing assembly.
Fig. 5 shows a schematic structural view of a nebulizer 100a of yet another embodiment; the porous body 30a is configured in the shape of a hollow column extending in the longitudinal direction of the atomizer 100a, and the heating element 40a is formed in the columnar hollow of the porous body 30 a. In use, as indicated by arrow R1, the liquid substrate of the reservoir 20a is absorbed along the outer surface of the porous body 30a in the radial direction and then heated and vaporized to generate aerosol in the heating element 40a transferred to the inner surface; the generated aerosol is output from the inside of the columnar hollow of the porous body 30a in the longitudinal direction of the atomizer 100 a.
In order to distinguish whether the replaced atomizer 100/100a is of an adaptable type, the identification and determination of the atomizer 100/100a is made in one embodiment of the present application by the controller 220 detecting a change in resistance of the heating element 40/40a in operation.
Generally, since different atomizers 100/100a have heating elements 40/40a with different materials or models, they have different initial resistance values and different respective material TCRs (temperature coefficient of resistance) during heating, and their resistance changes during temperature rise are significantly different, and the atomizer 100/100a can be identified and judged according to the resistance changes.
Further, in order to enable the power supply mechanism 200 to detect the resistance change of the heating element 40/40a in real time, the power supply mechanism 200 further includes a resistance detection circuit for detecting the resistance value of the heating element 40/40 a; the structure of the resistance detection circuit in a conventional embodiment is shown in fig. 6, and includes:
a standard resistor R1 for establishing a voltage divider circuit in series with the attached heating element 40/40 a; the series voltage divider circuit is connected to ground through the switching tube Q1 to form a loop, and at this time, the controller 220 can obtain the resistance value of the heating element 40/40a by sampling the voltage to ground Vabc of the standard resistor R1 and then calculating through a voltage dividing formula.
Of course, the other resistors R2, R3, R4 in the circuit shown in fig. 6 are the basic conventional functions of general voltage reduction, current limiting, and the like.
In other variations, the resistance detection circuit may also employ a constant current source when the atomizer 100/100a is incorporated into the power mechanism 200 such that the heating element 40/40a is coupled to the circuit; the constant current source provides a constant current detection current to the heating element 40/40a, and the controller 220 samples the voltage of the heating element 40/40a at the constant current through the sampling pin, and then calculates to obtain the resistance value of the heating element 40/40 a.
For example, fig. 7 illustrates a graph of the change in resistance of the heating element 40 of the atomizer 100 of one embodiment over a continuous puff representing a single puff by a user; according to the tested curve, the time axis is 60ms each, and the total detected data sampling time length is 60 × 60 to 3600ms to 3.6 s. During the test, the initial resistance value of the heating element 40 is 1.1 ohm, and the power supplied by the power supply mechanism 200 to the heating element 40 is 10W (generally, the output voltage of the electronic atomization device product in the field is 3.5V after the battery cell 210 is fully charged, and in combination with the effective voltage of the actual output of about 3.2V and the heat loss, setting the output power to be constant at 10W is the most commonly used constant power output value). In the graph of fig. 7, the variation in the resistance value of the heating element 40 comprises three phases:
s1 first stage: in the initial heating stage, the heating element 40 is heated from normal temperature rapidly, and the temperature is not raised to be higher than the boiling point of the liquid matrix; most of the heat is absorbed by the heating element 40 at this stage, and accordingly the resistance of the heating element 40 is rapidly increased due to the TCR;
s2 second stage: during the continuous heating of the heating element 40 in this stage, part of the heat of the heating element 40 is absorbed by the low-boiling point components (such as propylene glycol, perfume components, etc.) in the liquid matrix to form aerosol, and the efficiency of increasing the resistance value of the heating element 40 gradually decreases in this stage;
s3 third stage: during this phase, the heating efficiency of the heating element 40 is balanced with the vaporization efficiency of the liquid substrate due to the temperature rise of the heating element 40 to a temperature at which the liquid substrate is substantially vaporized; the resistance value of the heating element 40 is substantially constant in this phase, fluctuating substantially within a small range, until the end of pumping.
In the above description in connection with the actual resistance detected in the specific embodiment, the significant increase in resistance can be expressed as the amount of change in resistance per unit time (i.e. the slope of the tangent of the curve) or as the resistance value rising above a certain reference threshold, i.e. the resistance is considered to be significantly increasing.
In order to identify and distinguish the different atomizers 100, the following shows the sampling results of the resistance values of the heating elements 40 in the power supply tests of the power supply mechanisms 200 each supplying power of 7W to 5 different atomizers 100. Of course, in order to eliminate the error of the single sampling from the sampling detection result of the nebulizer 100 of each embodiment, the sampling of the nebulizer 100 of each embodiment is repeated by 2 times, which are respectively denoted as "sample 1" and "sample 2". The specific sampling results are shown in the following table, the sampling results of the examples in the following table are averaged, and a curve of the resistance with time obtained by fitting is shown in fig. 8.
As can be seen from the above table and fig. 8, the difference between the 2 repetitions of control "sample 1" and "sample 2" for the nebulizer 100 in each example is less than 1% of the sample data, and the sampling error can be considered satisfactory. If the data is required to have higher accuracy, more sampling times can be added, and then it is better to take the average of the data of the above "sample 1" and "sample 2" as the detection result.
Further according to the above table, the initial resistance values of the heating elements 40 of the atomizer 100 of example 1 are 0.75m Ω on average, the initial resistance values of the heating elements 40 of the atomizer 100 of example 2 are 0.75m Ω on average, the initial resistance values of the heating elements 40 of the atomizer 100 of example 3 are 0.75m Ω on average, the initial resistance values of the heating elements 40 of the atomizer 100 of example 4 are 0.71m Ω on average, and the initial resistance values of the heating elements 40 of the atomizer 100 of example 5 are 0.71m Ω on average. Wherein the initial values of the heating elements 40 of examples 1 to 3 are substantially the same; the initial values of the heating elements 40 of example 4 and example 5 were substantially the same.
Further, the material of the heating element 40 of the atomizer 100 in example 1 was prepared from FeSi15 (FeSi alloy containing Si 15%), and its TCR value was 1443 ppm; the material of the heating element 40 of the atomizer 100 in example 2 was FeSi10, and the TCR value was 1245 ppm; the material of the heating element 40 of the atomizer 100 in example 3 was made of stainless steel 304, and the TCR value thereof was 1038 ppm; the material of the heating element 40 of the atomizer 100 in example 4 was made of stainless steel 317L, which had a TCR value of 956 ppm; the heating element 40 of the atomizer 100 of example 5 was made of NiCr30Si1.45 alloy, which has a TCR of 890 ppm.
Resistance versus time curves for the samples of examples 1-5 in fig. 8; as is apparent from fig. 8, since the heating elements 40 have different TCR values respectively in the smoking test, the resistances of the atomizers 100 of the embodiments are changed differently during the aerosol generation process of atomizing the liquid substrate in the constant power output mode as is common in the art; further, the resistance-time curve or the rate of change of the resistance can be used to identify and distinguish different atomizers 100.
During the test of the atomizers 100 of further embodiments, the power supplied to them by the battery cells 210 is predetermined; and in order to ensure that the detection results are not affected by the difference in the supplied power, the predetermined power supplied to them is the same.
Further, a threshold range that best fits the resistance change of the heating element 40 in the atomizer 100 is stored in the controller 220; and then, comparing the sampled value of the resistance change obtained by sampling in the detection process with the stored threshold range, and distinguishing and judging whether the currently replaced atomizer 100 is the optimal atomizer 100 or not according to the comparison result. Meanwhile, when the above comparison results do not match, the controller 220 prevents the cell 210 from supplying power to the nebulizer 100.
Further in a preferred implementation, the controller 220 may further calculate a TCR value of the heating element 40 based on the change in resistance of the heating element 40 during operation, and then identify and determine whether the currently replaced nebulizer 100 is a suitable or adapted nebulizer 100 based on the TCR value.
As can be further seen from the sample data of fig. 8 and the above table, the resistance value of the heating element 40 as it is raised to substantially constant and/or the difference between the resistance value of the heating element 40 as it is raised to substantially constant and the initial resistance value for different atomizers 100 at constant power are different due to their different TCRs; in yet another implementation, the controller 220 may identify and distinguish different atomizers 100 based on the resistance value of the heating element 40 when it is raised to a substantially constant value, and/or the magnitude or difference of the rise.
As can be further seen from the sample data of fig. 8 and the above table, the rate of change of resistance of the heating element 40 over a predetermined time is different for different atomizers 100 at constant power due to the difference in the rate of change of resistance for their TCRs. The controller 220 may then identify and distinguish different atomizers 100 based on the rate of change of resistance of the heating element 40 over a predetermined time. For example, fig. 9 shows a schematic diagram of a process for identifying the nebulizer 100 over a predetermined time period of 0ms to 2000 ms; according to the graph shown in fig. 9, the resistance change curves corresponding to the atomizers 100 of different embodiments in the time period are respectively shown as L1-L5; and the slopes of the resistance change curves L1-L5 of the atomizers 100 of different embodiments when the resistance change curves rise from the initial value to be basically stable are obviously different, so that different atomizers 100 can be identified and distinguished by calculating the slopes.
In other alternative implementations, the predetermined time may also be another time period, such as 500ms to 1600ms, 300ms to 1200ms, or the like.
Based on the above, yet another embodiment of the present application further proposes a method of identifying and distinguishing between different atomizers 100, comprising the steps of:
s10, information about the atomizer 100 is determined based on a relationship between the power supplied to the heating element 40 of the atomizer 100 and the resulting change in the resistance value of the heating element 40.
In the above power supply process, according to a general practice of products in the art, power is supplied to the heating element 40 at a constant power output in a more preferred practice. In a more preferred implementation, the power provided to the nebulizer 100 during the above identified and respectively different nebulizers 100 is the same as the output power during the puff set by the power mechanism 200, e.g., a constant power of 7W or 10W as described above.
Further in a preferred implementation, the above methods and steps of detection are performed in a first puff after the user couples the nebulizer 100 to the power mechanism 200. Avoiding automatically performing the above steps in non-puffs to provide power to the nebulizer 100 results in smoke being emitted that is not generated by a user puff.
Further, based on the relationship between the power supplied to the heating element 40 of the atomizer 100 and the resulting change in the resistance value of the heating element 40, a resistance temperature coefficient value of the heating element 40 is determined, and the resistance temperature coefficient value is compared with a stored threshold range, and the atomizer 100 is determined based on the comparison result.
Identifying and resolving the contents of the nebulizer 100 includes: type of liquid matrix, heating pattern, anti-counterfeiting information, etc. Further, the power supply mechanism 200 may prevent the cell 210 from outputting power when the above identified content does not match the nebulizer 100 that is acceptable to the power supply mechanism 200.
Further, based on comparing the change of the resistance value generated by the heating element 40 within the predetermined time with the preset threshold, the power provided by the battery cell 210 to the heating element 40 is changed or adjusted according to the comparison result. In an alternative implementation, changing or adjusting the power provided by the battery cell 210 to the heating element 40 may be to prevent power from being supplied to the atomizer 100 when the comparison result exceeds a maximum value or a minimum value of a preset threshold value. Or in a further optional implementation, the preset threshold includes a plurality of thresholds, and each preset threshold corresponds to a different optimal heating curve or power; according to the comparison result, the electric core 210 can be further changed or adjusted to supply power to the atomizer 100 with the optimal heating curve or power, respectively.
It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
