In the description of the invention, the meaning of a plurality of the terms is one or more, the meaning of a plurality of the terms is two or more, and the terms larger, smaller, larger, etc. are understood to include no essential numbers, and the terms larger, smaller, etc. are understood to include essential numbers. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
In the description of the invention, unless otherwise explicitly defined, terms such as arrangement, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the terms in the invention in combination with the specific contents of the technical solutions.
The invention discloses a method for detecting the amount of tobacco tar and an aerosol generating device, which mainly aim to realize the purpose of judging whether tobacco juice is used up or not by changing a control panel 1 and a program code thereof, do not need to additionally introduce too many sensors, and have simple structure. The invention relates to the principle that when the heating wire heats the tobacco juice, the tobacco juice is evaporated and atomized to take away a large amount of heat, so that the heat of the heating wire can be effectively transferred out; when the tobacco juice is exhausted, the heating wire can not effectively dissipate heat, energy can be gradually accumulated to heat up, and whether the tobacco juice is exhausted can be indirectly reflected by reasonably monitoring the temperature change of the heating wire.
In the traditional scheme, the situation that the tobacco juice is directly obtained by various methods is really advisable, but other parts need to be introduced, the structure is complex, and the assembly is not facilitated. The control panel 1 is mainly changed, the modularized and integrated design is realized, the design concept is novel, and the technical content is high.
A method for detecting the amount of tobacco tar at least comprises a control panel 1, a power supply battery 3, a heating wire and tobacco juice, wherein the control panel 1 can form a bottom system, the power supply battery 3 supplies power to the heating wire through the control panel 1, and the heating wire is heated to evaporate and atomize the tobacco juice. Control panel 1 includes memory and treater, sets up a safe temperature threshold value and duration threshold value in the memory, control panel 1 acquires the temperature of heater strip, then judges whether the temperature of heater strip is higher than safe temperature threshold value, judges whether the temperature of heater strip still exceeds the duration threshold value after exceeding safe temperature threshold value, satisfies above-mentioned two conditions simultaneously behind control panel 1 and judges that the tobacco juice exhausts, interrupts the electric current between power supply battery 3 and the heater strip. The two conditions are in a progressive relationship, and if the temperature of the heating wire does not exceed the safety temperature threshold, the duration time threshold does not need to be judged. In the scheme, the safe temperature threshold value and the duration threshold value are introduced simultaneously, the condition that the heating wires are accidentally overheated is reduced (for example, the smoke liquid is properly inclined relative to the heating wires, the heating wires just have a certain position to float out of the smoke liquid, the temperature of the small section of the heating wires can be raised, if only one parameter is judged to possibly generate misjudgment, generally speaking, a user can repeatedly adjust the posture, the liquid level of the smoke liquid can also be repeatedly changed, the heating wires are naturally and organically covered again), and whether the smoke liquid is exhausted or not is comprehensively and accurately judged.
Considering that the change of heater strip can arouse the resistance change of heater strip itself, so obtain the resistance of heater strip alright obtain the temperature of corresponding heater strip, in this embodiment, control panel 1 obtains the resistance change condition of heater strip, changes safe temperature threshold value into safe resistance threshold value. Compared with direct temperature monitoring, the resistance change monitoring is more convenient, the temperature of the heating wire can be acquired indirectly through the resistance change monitoring, and particularly, the monitoring module can be integrated on the control board 1, so that the structure is smaller; the duration threshold itself can be integrated in the control board 1, so the present solution does not adjust the module. The resistance-temperature equation is as follows:
wherein: r is the resistance, and R is the resistance,
is the resistivity at a temperature of 0 c,
is the temperature coefficient of resistance, t is the temperature, L is the length of the heater wire, and S is the cross-sectional area of the heater wire. In order to ensure accuracy, it is necessary to measure the parameters of the heating wire reasonably, in particular to check the length change and the cross-sectional area change accurately when bending the heating wire.
In other embodiments, generally, the control board 1 supplies power to the heating wire, when the control board 1 supplies direct current with stable voltage to the heating wire, the change of the resistance value of the heating wire is reflected as the change of the power of the heating wire, and the control board 1 obtains the power change of the heating wire and changes the safety resistance value threshold value into the safety power threshold value. By adopting the technical scheme, the power change is more convenient to monitor, the temperature of the heating wire can be acquired through the indirect monitoring, and particularly, the monitoring module can be integrated on the control panel 1, so that the structure is smaller and more exquisite; the duration threshold itself can be integrated in the control board 1, so the present solution does not adjust the module.
Wherein: p is power, U is constant voltage, and R is resistance of the heating wire. This step requires the control board 1 to stably supply voltage, and has high quality requirements for the control board 1.
By integrating the scheme, the temperature of the heating wire is better reflected through the resistance.
In this embodiment, the control board 1 sends out a prompt of smoke liquid exhaustion after interrupting the connection between the power supply battery 3 and the heating wire.
