It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The present application will be described in detail with reference to the accompanying drawings and examples.
The applicant studied the temperature rise profile and the number of user suction openings over time for electronic nebulization devices at different powers. Referring to fig. 1, fig. 1 is a temperature rise curve of a conventional electronic atomizer under different powers; when the heating power is 6.5 watts, the heating is carried out for 1.5 seconds to reach the thermal equilibrium, and the thermal equilibrium temperature is 246 ℃; when the heating power is 7.5 watts, the heating is carried out for 0.8 second to reach the thermal equilibrium, and the thermal equilibrium temperature is 262 ℃ specifically; when the heating power is 8.5 watts, the heating is carried out for 0.25 second to reach the thermal equilibrium, and the thermal equilibrium temperature is specifically 302 ℃; when the heating power is 9.5 watts, the heating is carried out for 0.1 second to reach the thermal equilibrium, and the thermal equilibrium temperature is 340 ℃; therefore, the problem that the temperature is too high and the harmful substances such as heavy metals, aldehydes and ketones and the like exceed the standard possibly exists when the heating power of the electronic atomization device 100 is too high; the problem of poor reduction degree of atomized fragrance may exist when the heating power is too low; and as shown in fig. 2, fig. 2 is a graph of the number of user suction openings as a function of time; wherein the number of sampling persons is 40 persons, and the number of suction openings of each person is 200 openings; as can be seen from fig. 2, although the pumping habits of each user are different, the pumping time of the user is concentrated on 0.6 to 2.5 seconds. Meanwhile, due to the difference of the user's smoking habits, if the same mode is used for continuous or repeated heating, the change difference of the gradual temperature rise of the heating element 101 is large, so that the aerosol formed by atomization has poor taste consistency.
Referring to fig. 3, fig. 3 is a flowchart illustrating a heating control method according to an embodiment of the present application; in the present embodiment, a heating control method is provided, which is applicable to the heating element 101 of the electronic atomization device 100; wherein the electronic atomization device 100 is configured to heat and atomize an aerosol-generating substrate to form an aerosol, the aerosol-generating substrate comprising a liquid or solid of a flavor or active ingredient, the active ingredient being nicotine or a nicotine salt, or the like; specifically, the electronic atomizer 100 includes an atomizer and a host. The atomizer and the host are detachably connected. Wherein the atomizer is used for heating and atomizing the aerosol-generating substrate when electrified; the power supply assembly is arranged in the host, and the atomizer is inserted into one end port of the host and is connected with the power supply assembly in the host so as to supply power to the atomizer through the power supply assembly. When the atomizer needs to be replaced, the atomizer can be detached and a new atomizer can be installed on the host machine, so that the host machine can be reused. Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device, such as a microphone, a bracket, etc., and the specific structures and functions of these components are the same as or similar to those in the prior art, which can be referred to in the prior art specifically, and will not be described herein again.
Specifically, the heating control method includes:
step S11: and controlling the heating element to be heated to a first preset temperature in a first time period.
Specifically, the heating can be performed by constant power or by at least two different powers during the first time period.
In one embodiment, the heating is performed by at least two different powers for a first period of time to control the heating element 101 to increase from the ambient temperature to a first preset temperature; wherein the first time period is not more than 0.5 second so as to shorten the preheating time, accelerate the temperature rise and improve the atomization efficiency; in particular, the first predetermined temperature is not less than the boiling temperature of the current aerosol-generating substrate and less than the generation temperature of the hazardous substance. For example, liquid aerosol-generating substrates typically include Vegetable Glycerin (VG), Propylene Glycol (PG), and flavors and the like of various flavors; wherein the boiling point of the propylene glycol is about 185 ℃, and the boiling point of the vegetable glycerin is about 290 ℃. Although higher temperatures are beneficial for increasing the amount of atomisation, aerosol-generating substrates which are too hot may decompose to produce hazardous materials such as aldehydes and ketones; therefore, the current heating temperature is comprehensively considered to quickly reach the atomization temperature of the aerosol generating substrate, the aerosol generating substrate is favorably atomized, and the problem that harmful substances such as aldehydes and ketones exceed standards is avoided. Specifically, the setting range of the first preset temperature may be 220-. Preferably, the setting range of the first preset temperature can be 250-300 ℃. It is understood that the first preset temperature may be any one of the above ranges of 250 degrees celsius, 280 degrees celsius, and 300 degrees celsius. Meanwhile, according to the actual requirement of temperature control accuracy, the first preset temperature may also be a range fluctuating within a preset range, such as: the preset first preset temperature is 280 ℃, but the actual temperature is 270-290 ℃.
In one embodiment, at least two different powers may be sequentially reduced for heating; and each power value may range from 8 watts to 11 watts; also, the heating times for the at least two different amounts of power may be the same or different. It can be understood that the heating curves can be smoothed by sequentially reducing the power for heating, so that the temperature in the first time period of the temperature rise stage is smoothly transited to the first preset temperature; the temperature is prevented from being higher than the first preset temperature in the temperature rising stage.
In a specific implementation process, three different powers can be adopted for heating, and the heating time is the same; in this embodiment, in step S11, any one of the following two schemes may be specifically adopted; scheme one a 1: controlling the heating element 101 to heat for a first time period by 11 watts for 0.1 second, by 9 watts for 0.1 second, and then by 8 watts for 0.1 second to warm from ambient temperature to a first preset temperature; in this embodiment, the first predetermined temperature range may be 310 ℃ > and 320 ℃; scheme two a 2: controlling the heating element 101 to heat for 0.1 second through 10 watts, then for 0.1 second through 9 watts, and then for 0.1 second through 8 watts to increase from ambient temperature to a first preset temperature for a first period of time; in this embodiment, the first predetermined temperature may be in the range of 290 ℃ to 300 ℃.
Of course, in other embodiments, because the time of the first time period is shorter, the time period may also be continuously heated with a constant heating power, for example, by controlling the heating element 101 to increase from the ambient temperature to the first preset temperature in the first time period according to the third or fourth scheme; wherein, the third scheme A3 is as follows: controlling the heating element 101 to heat from the ambient temperature to a first preset temperature by 10 watts for 0.2 seconds during a first time period; scheme four a4 is: during the first time period, the heating element 101 is controlled to heat from ambient temperature to the first preset temperature by 10 watts for 0.4 seconds.
Step S12: and controlling the heating element to continuously work at the first preset temperature in the second time period.
Specifically, the minimum heating power in the first time period is not less than the maximum heating power in the second time period, so that the first time period can be rapidly heated, and the problem that harmful substances are generated due to overhigh temperature caused by overhigh heating power in the second time period is solved; specifically, the heating may be performed by a constant power or at least two different powers during the second period, but the heating element 101 is controlled to be heated by at least two different powers during at least one of the first period and the second period.
In one embodiment, if the first time period is heated by at least two different powers, as in step S11 implemented by option one a1 or option two a1, step S12 may be heated by a constant heating power to continuously operate at a first preset temperature, for example, during the second time period, the heating is performed by option one B1 or option two B2; wherein, the first scheme B1 is: controlling the heating element 101 to operate continuously at the first preset temperature by 6.5 watts for 2.7 seconds during the second time period; scheme two B2 is: during the second time period, the heating element 101 was controlled to operate continuously at the first preset temperature by heating at 7 watts for 2.7 seconds.
Of course, the heating may also be performed by at least two different powers during the second time period to control the heating element 101 to operate continuously at the first preset temperature; it should be noted that, in this case, the first time period may also be heated by constant power; wherein the time range of the second time period may be 2 to 3 seconds; because the first preset temperature is not lower than the boiling temperature of the aerosol generating substrate and is lower than the generating temperature of harmful substances such as aldehydes and ketones, the atomization efficiency of the electronic atomization device 100 can be ensured, and the problem that the existing harmful substances exceed the standard can be prevented.
When the heating is performed by at least two different powers in the second time period, the step S12 may specifically perform the heating alternately by using at least two different power cycles, and the heating time of the at least two different powers may be the same or different; wherein, each of the at least two different powers in step S12 may range from 6 watts to 7.5 watts.
