Preferably, the phase control according to the invention is implemented with a frequency from about 100 Hz to about 10 kHz during tightening, preferably with a frequency of approximately 1 kHz.

The invention will be described herein only as an example, with reference to the accompanying drawings, on which:

Figure 1 is a schematic drawing electrically heated systems for generation of an aerosol obrotowe the aerosol basis, inserted into the system;

Figure 2 is a graph illustrating change of the resistivity of the heating blades with temperature.

Figure 1 is a simplified view showing the inside of the case for electrically heated system 100 generate the aerosol. In particular, elements electrically heated system 100 generate aerosol shown are not to scale. Items that are not important for the understanding of the invention, not shown to simplify Fig 1.

Electrically heated system 100 generate the aerosol includes a housing 10 and forming an aerosol of the base 2, for example, a cigarette. Forming an aerosol of the base 2 is pushed into the housing 10 to come in thermal proximity with the heating element 20. Forming aerosol pillar 2 will release a number of volatile compounds at different temperatures. Some of the volatile compounds released from aerosol forming bases 2, are formed only as a result of the heating process. Each volatile compound will be released above the characteristic temperature of the release. Controlling the maximum operating temperature of electrically heated system 100 generate the aerosol so that it was lower than the temperature of the release of some of the volatile compounds, it is possible to eliminate the release or formation of the quiet components of smoke.

In addition, the housing 10 includes a source 40 of electrical energy, for example, rechargeable lithium-ion battery. The controller 30 is connected with the heating element 20, a source 40 of the electrical energy detector 32 forming the aerosol basis, the detector 34 and tightening graphical interface 36, such as a display.

The detector 32 forming the aerosol fundamentals detects the presence of aerosol forming basics 2 in thermal proximity with the heating element 20 and signals the controller 30 on the availability of aerosol forming basics 2.

The detector 34 detects tightening the air flow in the system, indicating a tightening adopted through an electrically heated system 100 generate the aerosol. The detector 34 of the torque signals to the controller 30 such tightening.

The controller 30 controls the interface 36 of the user to display information about the system, for example, battery capacity, temperature, status, forming the aerosol basics 2 other messages, or combinations thereof.

The controller 30 also controls the maximum operating temperature of the heating element 20.

Figure 2 shows a graph of the dependence of the resistivity ρ (Rho) on temperature for the conventional alloy of iron-aluminum (FeAl), is used as the heating element 20 in the embodiment described with exile of left-wing is in figure 1. The characteristic of the real resistivity ρ will vary depending on the exact alloy composition and geometric configuration of the heating element 20. The graph in figure 2 is only an example.

Figure 2 shows that the resistivity ρ increases with increasing temperature. Thus, knowledge of the specific resistance ρ at any given point in time can be used to display the actual operating temperature of the heating element 20.

The resistance of the heating element R=V/I where V is the voltage on the heating element, and I is the current passing through the heating element 20. The resistance R depends on the configuration of the heating element 20, as well as on temperature and is expressed by the following dependency:

R=ρ(T)∗L/Sequation 1

where ρ(T) is the temperature-dependent resistivity, L is the length and S is the cross-sectional area of the heating element 20. L and S are fixed for a given configuration of the heating element 20 and can be measured. Thus, for a given execution of the heating element R is proportional to ρ(T).

The resistivity ρ(T) of the heating element can be expressed as INR is Olena as follows:

ρ(T)=ρabout∗(1+α1T+α2T2)equation 2

where ρaboutis the resistivity at the reference temperature Taboutand α1and α2the coefficients of the polynomial.

Thus, knowing the length and cross-section of the heating element 20, it is possible to determine the resistance R and, hence, the resistivity ρ at a given temperature by measuring the voltage V and current I in the heating element. The temperature can be obtained simply from the informational table of the characteristic dependence of resistivity on temperature for your heating element or by evaluating the polynomial above equation (2). Preferably, this process can be simplified by representing the curve of dependence of the resistivity ρ of temperature in one or more, preferably two, linear approximations in the temperature range applicable to tobacco. This simplifies the evaluation of the temperature, it is desirable that the controller 30 with limited computational resources.

In preparation for management maximum operating temperature choose the maximum temperature electr the Cesky heated system 100 generate the aerosol. This choice is based on the temperature of the release of those volatile compounds that should or should not be released. Then this preset value is stored in the controller 30 together with the allowable range, for example, minus 5% of the specified maximum operating temperature.

The controller 30 heats the heating element 20 through the supply of electric energy to the heating element 20. Preferably, to save power, the controller heats the heating element 20 only if the detector 32 forming the aerosol fundamentals discovered aerosol forming the base 20 and the detector 34 tightening discovered tightening.

In use, the controller 30 measures the resistivity ρ of the heating element 20. Then, the controller 30 converts the resistivity of the heating element 20 in the magnitude of the actual operating temperature of the heating element, by comparing the measured resistivity ρ with a lookup table. In the next step, the controller 30 compares the actual operating temperature with a predetermined maximum operating temperature. If the actual operating temperature is below the lower range of the specified maximum operating temperature, the controller 30 supplies the heating element 20 additional electrical energy to increase the real slave who can sense the temperature of the heating element 20. If the actual operating temperature is above the upper range of the specified maximum operating temperature, the controller 30 reduces the electrical energy supplied to the heating element 20, in order to reduce the actual operating temperature back to the acceptable range specified maximum operating temperature.

Temperature control of the heating element on the basis of the specific resistance ρ of the heating element is not limited to an electrically heated system generating the aerosol, as described with reference to figure 1, but is applicable to any electrically heated system generating the aerosol, in which the heating element 20 transfers thermal energy to tobacco or other aerosol forming the basis of releasing volatile compounds.
