Definitions
- the present invention relates to a method for regulating the evaporation of an evaporator in an inhaler, the evaporator being heated by means of electrical resistance heating and an electronic control device regulating the flow of current through the evaporator.
- a resistive evaporator is electrically connected to an energy store via an electronic switching element so that when the switching element is closed, the voltage of the energy store is applied to the evaporator and a heating current flows.
- the switch is usually operated by the electronic control device.
- the temperature at the evaporator is typically determined using a temperature-dependent electrical resistance of the evaporator.
- the temperature of the evaporator can be set in a targeted manner through the relationship between temperature and the electrical resistance of the evaporator.
- the temperature should not exceed a temperature determined by the liquid to be evaporated, since otherwise pollutants can arise, in particular if the evaporator falls dry.
- the circuit of an evaporator or heater can be described in simplified form as a series circuit of electrical resistors. Elements of this series connection include an electrical resistance of the evaporator (evaporator resistance), a battery internal resistance and undesirable parasitic electrical resistances.
- the parasitic resistances are given, for example, by the following resistances: an electrical resistor belonging to the electrical control device, a current measuring resistor, an electrical resistance of the supply lines, in particular through connecting wires, copper conductor tracks and / or soldering points and possibly an electrical resistance was a possible plug connection.
- the parasitic resistance is neither constant over time nor reproducible, since, for example, plug connections, depending on the state of aging, contamination and / or deformation, have an influence on the parasitic resistance that can only be measured with considerable effort.
- Temperature measurement errors due to parasitic resistances can lead to overheating of the liquid to be evaporated, which can lead to nucleate boiling or the formation of pollutants. Due to the various errors caused by measurements and parasitic currents, the evaporator can only be insufficiently controlled with known methods.
- the object of the invention is to provide a method with which the evaporation can be effectively and reliably controlled and overheating of the liquid to be evaporated can be reliably avoided.
- the method comprises the following steps: Time-sequential recording of measured values of the current applied to the evaporator from a starting point. From the starting point, a current flows through the evaporator. The evaporator heats up due to the flow of current and the temperature-dependent electrical resistance of the evaporator. Due to the As the evaporator warms up, the temperature-dependent electrical resistance of the evaporator changes.
- the measurement can advantageously be switched on by a demand request from a user of the inhaler, in particular by pulling on an electronic cigarette. Accordingly, the measurement can be switched off after the request has ended.
- a transition point between a range of low and in particular up to no evaporation and a range of high evaporation, in particular during consumption is determined in a time-dependent current measurement series corresponding to the measured values.
- the transition point marks the point in time at which evaporation occurs and the evaporator is not heated significantly further.
- the invention has recognized that from the transition point evaporation takes place to such a high degree that no or hardly any further heating of the evaporator takes place.
- the energy provided by the flow of current at the evaporator is converted into energy for evaporating the liquid and not at all or only to a small extent in heating the evaporator. Therefore, from the transition point, the temperature of the evaporator changes to a lesser extent than at the time before the transition point.
- the transition point in the current measurement series can thus be understood as a kink point in the relationship between current and measurement point or time.
- a current value I v corresponding to the transition point is determined from the transition point, at which a reliable evaporation takes place.
- a current interval [li; b] as a function of the determined current value l v and a regulation of the Current flow within the specified current interval [h; l 2 ]. This allows the power of the evaporator to be precisely regulated.
- the method according to the invention has the advantage that the evaporator temperature does not have to be known and the value, in particular of the parasitic electrical resistance, does not need to be determined in real time and for each individual evaporator.
- the decisive factor is at which current or which heating power the evaporation occurs through the respective evaporator.
- the occurrence of evaporation is determined on the basis of the series of measurements and thus determines the heating current to be applied within the current interval [h; l 2 ].
- the transition point is advantageously determined on the basis of a regression along the current measurement series in order to be able to determine the transition point reliably and effectively.
- a regression is based on a plurality of measured values, with which measurement errors and / or statistical errors can be minimized.
- the regression is advantageous compared to, for example, a finite difference method, in which only two adjacent measured values in particular are considered and a measurement inaccuracy has a particularly strong effect on the result.
- the transition point of at least one best-fit straight line and / or at least one best-fit polynomial on the current measurement series is preferably determined in order to provide a numerically effective determination of the transition point.
- one or more regression lines and / or in particular square regression curves can be determined at different measurement points in the measurement series. From the temporal The transition point can be determined with the course of the rises associated with the regression lines or the curvatures associated with the regression curves.
- the curvature can in particular be determined from a coefficient of a quadratic term of the compensation polynomial.
- the transition point is preferably determined by a jump and / or the reaching of a threshold value of the rise or the gradient (1st derivative) of the current measurement series in order to further improve the identification of the transition point.
- the transition point is determined for this purpose by means of an ext rem value of the curvature of the current measurement series.
- Two successive measured values are preferably less than 1 0 ms, preferably less than 5 ms, more preferably less than 2 ms apart, in order to be able to resolve the transition point well in time and to record an advantageous number of measured values over the duration of a train can.
- the recorded measured values are preferably recorded over at least 10%, advantageously at least 30%, further advantageously at least 50% of a train length.
- the lower threshold h and / or the upper threshold b is set so that the lower threshold is less than the current value lv and / or the current value lv is less than the upper threshold l 2 , so that the heating current is reliable. Allowable by the current value lv in the current interval [L; l] can be regulated. If the lower threshold h is less than the current value lv, the evaporator can be prevented from falling dry, since the evaporator does not evaporate with a current between the lower threshold h and the current value lv, but heats the evaporator and / or the liquid.
- the current flow through the evaporator is preferably pulsed, the pulse duty factor being increased from above when the lower threshold h is reached and / or reduced from below when the upper threshold l 2 is reached.
- a reduction in the input power and an increase in the running time of a battery supplying the evaporator with electrical current can thus be achieved.
- the lower threshold h and / or the upper threshold l 2 is advantageously established as a function of an analysis of the average square current I L 2 over a defined time interval. If the average square current I L 2 falls below a predetermined threshold value, which can be determined, for example, from the current measurement series from a time interval after the starting point, this is to be interpreted as a sign of reduced contact between the evaporator and the liquid. In this case, the lower threshold h and / or the upper threshold l 2 should be shifted to lower currents.
- the current interval [h; l 2 ] and / or at least one of the thresholds h; l 2 shifted to lower flows in the course of time in order to prevent the evaporator from falling dry.
- the current interval [h; l 2 ] and / or at least one of the thresholds h; l 2 can also be adapted to a specified time function in order to effectively control the evaporation and a Adaptation to processes of differential distillation to enable.
- data relating to a plurality of time-dependent current measurement series are stored in a data memory and are compared with one another and / or with fixed parameters. This makes it possible to save the current measured values and transition points that occurred during the process.
- An automatic analysis can, for example, examine the point in time at which the evaporation flow lv was reached. If this point in time is reached later than a predetermined threshold value, this is an indication of an excessively high electrical resistance.
- the average square of the current can be evaluated during the evaporation process. If this is lower than a predetermined threshold value, conclusions can be drawn about the consumption of the liquid.
- the ambient temperature is preferably measured and the current interval [h; l 2 ] and / or at least one of its thresholds h, l 2 is fixed and / or adapted as a function of the measured ambient temperature in order to be able to take possible influences of the ambient temperature into account.
- the current flow is advantageously regulated by switching on and / or maintaining the current flow through the evaporator when the current is less than an upper threshold value I2, or by switching off the current flow through the evaporator when the current is greater than a lower threshold value l effective control method within the current interval [h; l 2 ] to be able to provide.

- the invention is not tied to a specific type of evaporator 60.
- the evaporator tank unit 20 is preferably verbun and / or connectable to a heating current source 71 controllable by the control device 1 5, which is connected to the evaporator 60 via electrical lines 25, so that an electrical heating current Ih generated by the heating current source 71 flows through the evaporator 60 flows. Due to the ohmic resistance of the electrically conductive evaporator 60, the flow of current leads to heating of the evaporator 60 and therefore to an evaporation of liquid present at the evaporator 60. Generated this way
- the evaporation temperature is preferably in the range between 100 ° C and 400 ° C, more preferably between 150 ° C and 350 ° C, even more preferably between 190 ° C and 290 ° C.
- the evaporator-tank unit 20 is set so that a liquid quantity preferably in the range between 1 pl and 20 pl, more preferably between 2 ml and 10 ml, even more preferably between 3 ml and 5 ml, typically 4 ml per Train of the consumer, is added.

- the evaporator 60 can be replaced if it is dirty, defective or used up, so that a separable electrical connection can be provided between the evaporator 60 and the base part 16.
- This connection can be designed as, for example, spring pins, plug-in or screw connections.
- FIG. 3 shows a schematic current measurement series 100, indicated by a bold black curve, with a determined transition point 101 at a current I v , this illustration being a Example of a current measurement series 100 for an evaporator 60 with a negative temperature coefficient shows.
- the current I is plotted against the time t and is shown as continuous for the sake of illustration only.
- the evaporator 60 At the beginning of a train at a starting point 1 10, which is determined for example by detecting the train by means of a pressure sensor or by being switched on by a consumer, the evaporator 60 is switched on and heated with a heating current. Measurement values 1 08 (shown schematically as a curve in FIG. 3) of the current I applied to the evaporator 60 from the starting point 1 1 0 onwards are then recorded in chronological order. The evaporator 60 heats up relatively quickly, so the measured current I falls from.
- the temporal current measurement series 100 has a transition point 101 which is recognizable as a kink point or at least a strong flattening which is determined as transition point 101 as soon as evaporation begins. This is followed by two-point control as a function of a current lv belonging to the transition point 101 with the lower threshold h and the upper threshold h, the current I in the current interval [h; 12] is regulated: as soon as the determined current flow I exceeds the upper threshold h, the current source is switched off or the current flow is reduced; as soon as the determined current flow I falls below the lower threshold b, the current source is switched on or the current flow is increased.
- the difference between the upper threshold B to the current lv at the transition point 102, and the difference of the current lv at the transition point 1 02 to the un direct threshold h is advantageously less than the current l v at the transition point 102, since no or only a small excess temperature at Evaporator 60 should occur and thus only a small change in current occurs.
- the advantage of the previously described method for regulating is illustrated using the lower current measurement series 200 in FIG.
- the lower current measurement series 200 shows a current curve for an evaporator 60 which differs in one or more points from the evaporator 60 of the bold current measurement series 100: the battery voltage is different, in particular due to the state of discharge or internal resistance; the heating resistance of the Ver evaporator 60 is different, in particular zen through production tolerances; other electrical resistances are present.
- the method according to the invention results in a temperature error which is one order of magnitude smaller than in the case of the resistive temperature determination according to the prior art. Since it is advantageous if the amount of the current interval 11 2 -j is less than 50%, advantageously less than 25%, further advantageously less than 10% of the amount of the current value I v .
- the process does not regulate to a fixed temperature, but to a current that corresponds to the evaporation temperature or a temperature slightly above the evaporation temperature. Since the evaporation temperature depends on the composition of the substrate or, in particular, the liquid, the temperature is not solut, but the current l v leading to the evaporation is determined.
- the current measurement series 100 comprises several measured values 108 recorded one after the other, which are represented by a corresponding number of points, each point representing a measured value 108 with an associated current I at a time t.
- the control device 15 calculates a best-fit straight line 102 from the measured values 108, for example by linear regression.
- two different best-fit straight lines 102 are shown at the times t 1 and t 2.
- the time course of the rise 109 of the best fit straight line 102 thus obtained is shown in FIG.
- the regression has the advantage that the transition point 1 01 can be easily localized, even if the current measurement series 100 is superimposed with noise.
- the regression thus smooths the increase 1 09 and offers an improvement over finite differences.
- FIG. 5 shows a determination of a transition point 101 on the basis of the rise 109 of the current measurement series 100 shown in FIG.
- the transition point 101 can be detected in real time by evaluating the first or second time derivative of the current I.
- the rise 1 09 is the rise of the regression line 10 02 determined by regression on the current measurement series 1 00 and is plotted against time t. If, for example, the amount of the increase 109 falls below a threshold value 103, it can be concluded that evaporation has started.
- the transition point 1 01 is located where the amount of the rise 109 of the best-fit straight line 1 02 is less than a threshold value 103 of 0.002 A / s in this example.
- the threshold value 103 can be determined empirically for the evaporator 60. From the time to, at which the rise 109 exceeds the threshold value 1 03, the evaporation current lv can be determined using the current measurement series 100, here for example approx. 2.6 A (see FIG. 4).
- FIG. 6 shows a determination of a transition point 1 01 based on the curvature 106 of the current measurement series 100 shown in FIG. 4.
- An extreme value 10 7 in the second derivative in particular a maximum, characterizes the transition point 101.
- the transition point 101 or the evaporation point of the current measurement series 101 can also be found via the curvature 1 06 of the current measurement series 100.
- a polynomial in particular of the second order, is locally fitted to a plurality of successive measured values 108 of the current measurement series 100 along the current measurement series 100.
- the coefficient of the quadratic term of the polynomial is determined as curvature 1 06 and plotted against time t.
- An algorithm for finding an extreme value 1 07 finds the extreme value 107 at a point in time t 0 , which corresponds to the point in time at which the current measurement series 100 has the transition point 101.
