DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric flavor producing article heating control device for controlling a heating temperature of a flavor producing article.

[0002]

2. Description of the Related Art When heating a heated object, it is common to directly detect the temperature of the heated object with a temperature sensor and control the temperature of the heated object based on the detected temperature. In flavor producing articles such as aerosol cigarettes, it is difficult to use a temperature sensor due to physical property factors.
In addition, when the flavor-generating article is given heat at a certain temperature or higher, the desired flavor performance cannot be obtained due to adverse effects such as thermal decomposition. Therefore, in order to control the heating of the flavor producing article, it is necessary to control the heating temperature of the flavor producing article by indirectly controlling the heat generation temperature of the heater.

Conventionally, a heating control device for an electric heater that does not use a temperature sensor has a configuration in which a power supply circuit of a heater serving as a heating element is turned off after a certain temperature rise. Soaring changes
It is difficult to stably maintain the temperature of the object to be heated.

[0004] Heating control techniques other than the above include:
A self-control type heater is used, or a temperature sensor is installed on the heater surface or inside the heater, and the temperature detected by the temperature sensor is taken into a heating control device to control the temperature of the heater.

[0005]

However, the heater for heating the flavor-generating article is naturally small in heater size because the flavor-generating article to which the flavor-generating article is applied is small in appearance. The heating rate of the heater also becomes relatively fast. As a result, a heating control device using a temperature sensor not only does not provide stable control characteristics due to the responsiveness and heat capacity of the sensor, but even if stable conditions are obtained at a specific temperature, it is optimal for flavor-generating products. There is a problem that it is difficult to set a proper temperature.

The present invention has been made in view of the above circumstances, and provides an electric flavor generation article heating control device that appropriately controls the heating temperature of a flavor generation article by using the electric resistance value of a heating element when energized. Is to do.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an electric flavor generation article heating control device for heating and controlling a flavor generation article to a predetermined temperature. A heating element for a flavor generation article whose electric resistance value changes according to the heat generation temperature is connected to the output side of the means,
Without using a temperature sensor, the electric resistance value is detected from a current value flowing through the heating element at the time of energization, and when the detected electric resistance value reaches a predetermined electric resistance value, an energizing path to the heating element is determined. In this configuration, on / off control is performed every time.

[0008] By taking such measures, when the heat generation temperature of the heating element for a flavor producing article rises due to energization,
Since the electric resistance value increases with this temperature rise, if this electric resistance value is used effectively, the heat generation temperature of the heating element and, consequently, the predetermined temperature of the flavor producing article can be grasped. When the predetermined temperature of the product is reached, the current path to the heating element is turned on without using a temperature sensor.
By performing the off-control, the flavor-producing article can be controlled to a predetermined heating temperature.

Another aspect of the present invention is a constant voltage generating means for generating a constant DC voltage, and a heat generating means for changing an electric resistance value according to a heat generating temperature when the constant voltage generating means receives a constant DC voltage when energized. A body, a resistance detecting means for detecting an electric resistance value from a current value flowing through the heating element at the time of energization, and a predetermined electric resistance value corresponding to a desired temperature of the heating element which does not cause the flavor pyrolysis of the flavor producing article. A resistance setting unit, a comparison operation unit that compares the predetermined electric resistance value with the electric resistance value detected by the resistance detection unit, and outputs a coincidence signal when the two values coincide with each other; And a sequence control means for controlling on / off of a current path to the heating element after receiving the signal.

[0010] By taking such measures, the electric resistance value is detected from the current value of the heating element whose electric resistance value changes according to the heat generation temperature at the time of energization. When a predetermined electric resistance value according to the desired temperature of the heating element is set, and the set electric resistance value is compared with the detected electric resistance value, it is determined that the heating element has reached the desired temperature from the coincidence of the two values. And can be detected reliably and with high accuracy without using a temperature sensor. Further, the sequence control means appropriately controls on / off of the current supply path to the heating element in response to the coincidence signal of the two values, whereby the heating element can be controlled to a desired temperature in a stable state.

Further, as the heating element, a ceramic heater which can be heated to a desired temperature at which the temperature rise rate is high at the time of energization and which does not cause the thermal decomposition of the flavor-generating article, is used to quickly produce the flavor-generating article. And the flavor performance of the flavor-producing article can be obtained.

Further, the constant voltage generating means generates a DC constant voltage such that the desired temperature of the heating element becomes 300 ° C. within 10 seconds of the current supply time at the time of initial power supply when the flavor generating article is not inserted. And the sequence control means includes:
When the flavor producing article is not inserted, the desired temperature of the heating element is 300
By controlling on / off of the current path to the heating element so as to have a temperature change range of ± 60 ° C with respect to ° C,
The flavor of the flavor-producing article can be quickly obtained in the current flavor-producing article, and the flavor can be secured in a stable state for a certain period of time.

Further, the sequence control means sets a sequence control time of an off-time and an on-time of an energizing path to the heating element in advance in consideration of thermal decomposition of the flavor of the flavor-generating article. When a coincidence signal is received from the controller, the on / off control of the current supply path to the heating element is performed in accordance with the sequence control time, so that the required flavor can be stably and continuously provided.

At the center of the rear end surface, a through hole 32 having a diameter sufficiently smaller than the heater insertion hole 31 is formed, and two opposing portions of the outer surface of the cylindrical wall 33 which is a solid portion of the molded body are formed with grooves along the axial direction. 34 are formed.

The heater insertion hole 31, the through hole 32 and the groove 34 function as a passage for conveying a heating gas containing flavor and aerosol components generated in the molded body 30, and
It has a function of securing an evaporation area on the molded body 30 so as to efficiently generate a heated gas containing flavor and aerosol components.

Reference numeral 28 denotes a small-diameter through-hole for introducing cooling air into the gas passage 24 formed in the casing 25. The heating gas containing the flavor and aerosol components generated in the molded body 30 is mixed and cooled with the outside air introduced through the through-holes 28 to promote the generation of the aerosol. Note that, instead of the through hole 28 for introducing outside air, a part of the casing 25 may be formed of a gas-permeable material, and the outside air may be introduced by using the ventilation characteristics of the wall of the casing 25.

By the way, the molded body 30 of the raw material, which is a medium that produces a flavor by heating without burning, includes a binder affected by thermal decomposition, a carrier material for preventing the volatilization of the flavor component, a flavor component, an aerosol base, Contains water and the like.

(2) Next, a description will be given of a heating control device for controlling the heating of the molded body 30 by mounting the flavor producing article 20 as described above.

FIG. 1 is a block diagram showing one embodiment of a heating control device according to the present invention.

In FIG. 1, reference numeral 1 denotes the flavor-producing article 2 described above.
A DC power supply 2 is applied to the heating heater 1 via a constant voltage generating circuit 3.

The heating heater 1 is a heater that generates heat due to a resistance loss at the time of energization, and has a characteristic that the resistance value R increases as the heat generation temperature T increases as shown in FIG. . The heating heater 1 is, specifically, a molded body 30.
A cylindrical rod-shaped metal heater (stainless steel pipe) having a smaller outer diameter than the hole diameter of the heater insertion hole 31 is used. The ceramic heater has a high temperature rising rate and can generate heat within a temperature range of 50 ° C. to 800 ° C. On the other hand, the ceramic heater is heated to a maximum temperature of about 300 ° C. which does not thermally decompose the flavor-producing article within 30 seconds, for example. There are advantages such as being able to. In view of the above-mentioned rate of temperature rise, the nichrome wire has a low rate of temperature rise, and thus is not suitable for heating this kind of flavor producing article.

The DC power supply 2 has a voltage of, for example, 3.8 V to 12.
A battery that generates any DC voltage within 0 V is used. The DC voltage of the DC power supply 2 is determined depending on whether or not desired flavor performance is obtained within a required time without thermally decomposing the flavor producing article 20. Incidentally, a 7.2 V DC voltage is required to heat the flavor producing article 20 to a temperature of 300 ° C. within 30 seconds without being thermally decomposed.

The constant voltage generating circuit 3 uses a three-terminal regulator, for example, and has a function of avoiding fluctuations in the power supply voltage due to fluctuations in the load of the heater 1 or the like and always applying a constant voltage to the heater 1. .

A series circuit comprising a heating heater 1, a current detection circuit 4 and a switch means 5 is connected between both output terminals of the constant voltage generation circuit 3.

The current detection circuit 4 uses, for example, a resistor having a small temperature coefficient and no temperature dependency, and changes with a rise in the resistance value due to a rise in the heating temperature of the heating heater 1. The current value is detected, converted into a voltage corresponding to the detected current, and output. The switch means 5 includes:
It is configured by a relay or a semiconductor switching element, and performs an on / off operation in response to an on / off control signal from the outside.

The constant voltage generating circuit 3 includes a heater 1 for heating.
The current detection circuit 4 must be set to a constant voltage application state that does not fluctuate, that is, it has a function to create appropriate resistance measurement conditions. The constant voltage generation circuit 3 and the current detection circuit 4 are referred to as a resistance detection circuit 6 having a function of detecting a changing resistance value of the heating heater 1 because of having a function of detecting a changing current value. Can be.

Further, the heating control device is provided with a temperature setting circuit 7 and a voltage conversion circuit 8. The temperature setting circuit 7 sets the resistance value Rs of the heating heater 1 at the optimum heating temperature Ts of the heating heater 1 as shown in FIG. It depends on the content, and therefore, the set resistance value Rs
Is also arbitrarily variable. The voltage conversion circuit 8 generates a voltage according to the resistance value set by the temperature setting circuit 7. These temperature setting circuit 7 and voltage conversion circuit 8
Specifically, for example, a predetermined voltage is applied to both ends of a variable resistor, and only the movable terminal preset in a portion of the variable resistor corresponding to the set resistance value Rs depends on the set resistance value Rs. The temperature setting circuit 7 and the voltage conversion circuit 8 can be called a resistance setting circuit 9.

A comparison operation circuit 10 compares a voltage corresponding to the detection current output from the current detection circuit 4 with a voltage output from the voltage conversion circuit 8, and a comparison result of these two voltages is used as a sequence control circuit. 11 is sent. The sequence control circuit 11 has a built-in timer, and when a voltage that matches the voltage output from the voltage conversion circuit 8 is detected by the current detection circuit 4, that is, when a match signal is received,
It has a function of outputting a sequence control signal for performing on / off control at a timing of a predetermined time set in advance while considering the thermal decomposition of the flavor generation article 20. When the sequence control circuit 11 receives the coincidence signal from the comparison operation circuit 10, for example, specifically outputs a sequence control signal for turning off for 0.2 seconds to 2 seconds, and then takes in the original comparison result and Or outputting a sequence control signal for repeatedly executing off / on at predetermined time intervals when the coincidence signal is received.

Reference numeral 12 denotes a switch drive control circuit, which controls on / off of the switch means 5 based on a sequence control signal input from the sequence control circuit 11.

The comparison operation circuit 10, sequence control circuit 11, switch drive control circuit 12, and switch means 5 constitute a heater power control device 13.

Next, the operation of the apparatus configured as described above will be described.

First, the resistance value Rs corresponding to the optimum heating temperature Ts of the heating heater 1 shown in FIG. 2 which does not cause the thermal decomposition of the flavor-generating article and obtains the flavor performance is obtained by using the resistance setting circuit 9. Set.

In this state, when the power is turned on to the apparatus, the sequence control circuit 11 starts a predetermined sequence control operation, outputs a sequence control signal for turning on the switch means 5, and outputs the signal via the switch drive control circuit 12. Switch 5 is turned on.

Here, when the switch means 5 is turned on,
A predetermined constant DC voltage is applied to the heater 1 from the constant voltage generation circuit 3. As a result, the heating heater 1
Generates heat due to resistance loss due to energization, and the electric resistance value of the heating heater 1 increases with an increase in the heat generation temperature. At this time, since a constant DC voltage is always applied to the heating heater 1, the resistance value increases as the heat generation temperature rises due to energization, and conversely, the current value flowing through the heating heater 1 decreases. The current detection circuit 4 detects a current flowing through the heating heater 1, converts the detected current into a voltage value, and converts the detected current into a voltage value.
Send to 0.

Here, the comparison operation circuit 10 compares a predetermined voltage depending on the set resistance inputted from the voltage conversion circuit 8 on the reference resistance setting side with the voltage outputted from the current detection circuit 4 to detect the current. When the voltage output from the circuit 4 matches the predetermined voltage, that is, when the resistance value corresponding to the set temperature and the resistance value of the heating heater 1 become equal, for example, a high level signal H is output and the sequence control circuit 11 To send to.

When the sequence control circuit 11 receives the high-level signal H from the comparison operation circuit 10, it outputs a sequence control signal for turning off the switch control circuit 12.
, The switch means 5 is turned off and the timer is operated at the same time. Thus, the supply of the low-voltage power to the heater 1 is stopped.

After that, based on a predetermined sequence program, the sequence control circuit 11 operates the switch after a predetermined period of time, for example, a timer, for example, 1 second has elapsed while taking into account the flavor pyrolysis of the flavor generation article 20. The switch means 5 is turned on via the control circuit 12, and thereafter,
On the basis of the comparison result of the comparison operation circuit 10, the switch means 5
Or the high level signal H
Then, after the switch means 5 is turned off, the on / off control is repeatedly executed at predetermined time intervals.

The shorter the on / off control time of the switch means 5, the narrower the temperature range at the time of control. However, the type of the on / off contact on the resistance detection circuit 6 side (relay, semiconductor switching). Element) and physical properties (specific heat and heat transfer coefficient) of the object to be heated, and the like.
It is desirable to carry out at intervals of about 2 to 2 seconds, but this time also differs depending on the state of the component content of the flavor producing article 20.

Further, as the cylindrical molded body 30, for example, a binder, a good heat transfer material, a supporting material, a flavor component, an aerosol base, and water are contained as described above. By appropriately selecting phosphate, cement, silica, gypsum, lime, starch, sugar, seaweed, protein, tobacco powder, etc., the optimal heating temperature of the flavor-producing article is about 300 ° C., Desirably, if the temperature change range is 300 ° C. ± 30 ° C., stable flavor performance can be obtained without thermal decomposition of the flavor. For example, when the binder is mainly composed of mineral clay, for example, ± 60 ° C. Temperature change range.

Therefore, according to the above-described embodiment, a constant DC voltage is always applied from the constant voltage generating circuit 3 to the heater 1 for heating. Using the changing resistance value of the heating heater 1 to detect the heat generation temperature of the heating heater 1,
It is not necessary to use a temperature sensor, and is very effective for controlling the heating temperature of a flavor-producing article that is small and requires a high rate of temperature rise.

Also, according to the resistance value obtained from the current value of the heating heater 1 whose resistance value changes according to the heat generation temperature at the time of energization, and the desired temperature of the heating heater 1 in which the flavor pyrolysis of the flavor producing article does not occur in advance. Since the desired heating temperature of the heater 1 is detected based on the coincidence of the two resistance values, the desired heating temperature of the heating heater 1 and the flavor generation can be reliably and accurately determined. The optimum heating temperature can be set for the article.

Further, when the sequence control circuit 11 receives the coincidence signal of the two resistance values from the comparison operation circuit 10, the sequence control circuit 11 controls the energization path of the heating heater 1 on and off at an arbitrary predetermined interval. The flavor performance can be stably and continuously obtained while considering the physical properties of the product.

In the above embodiment, an example in which a metal heater or a ceramic heater is used as the heating heater 1 has been described. However, for example, a platinum wire or a thermocouple as shown in FIGS. 3 and 4 is used. Is also good. FIG. 3 shows the on / off control and the PID (P: proportional, I: integral,
FIG. 9 is a diagram plotting a customary relationship between elapsed time and heater heat generation temperature when (D: differential) control is performed. As is apparent from this figure, both the on / off control and the PID control can quickly obtain the flavor performance of the flavor-producing article in that the temperature rise rate at the time of energization is high. However, in the case of the PID control, the heating heater is used. When the PID control is executed after the heat generation temperature of No. 1 rises from 250 ° C. to 300 ° C., the P and D control parameters are changed and the heat generation temperature changes greatly.
In the case of the off control, the heating temperature can be controlled so as to fall within a temperature variation range of 250 ° C. ± 20 ° C., and the flavor performance of the flavor generating article can be obtained in a stable state.

The same applies to the case of the heater 1 of the thermocouple shown in FIG. 4. The heating rate at the time of energization is high, and if on / off control is adopted, stable heating temperature control can be performed.

[0052]

As described above, according to the present invention, the following various effects can be obtained.

According to the first aspect of the present invention, the effective use of the resistance value that changes in response to the change in the heating temperature of the heating element allows the heating temperature of the heating element to be accurately detected, and without using a temperature sensor. In addition, the flavor producing article can be controlled to a predetermined heating temperature.

According to the second aspect of the present invention, the resistance value that changes according to the heat generation temperature of the heating element during energization is compared with a predetermined resistance value that corresponds to a predetermined optimum temperature for the flavor-producing article. Since the arrival of the optimal heating temperature of the heating element is detected based on the coincidence of the heating temperature, the heating temperature can be reliably and accurately controlled without using a temperature sensor. In addition, by controlling ON / OFF of the energizing path to the heating element appropriately by using a selective time as appropriate by the sequence control means, the heating element is controlled in an appropriate temperature change range in a stable state. it can.

According to the third aspect of the present invention, by using a ceramic heater as the heating element, it is possible to set an optimum heating temperature at which the flavor performance can be easily obtained for the flavor producing article.
