The invention further relates to the above described electronic aerosolization temperature control circuit.

The invention also relates to a temperature controllable electronic aerosolizing core.

Background technique

With the development of society and human progress, tobacco as a consumer product harmful to the human body is gradually being replaced by health products with the same function. Such as the recent rise of electronic cigarette products, this product is a high-tech means to atomize liquids containing chemicals such as nicotine to produce smoke for the purpose of smoking. At the same time, it is also possible to help to quit smoking by using different chemicals. It not only benefits the physical and mental health of smokers, but also contributes to environmental protection and saves social resources. Therefore, this kind of product is very popular among the majority of "smokers" and has a lot of profit space in the market.

At present, electronic cigarette products popular in the market generally atomize electronic cigarette liquid containing nicotine by electric heating, and people use a certain device to suck the electronic cigarette liquid that has been atomized, thereby achieving the purpose of smoking. Since this so-called smoke is completely free of solid particles, it is actually only a kind of fog, so the impact on the human body and the environment is very small.

At present, the atomization device of the electronic cigarette generally adopts a resistance wire to heat and heat, and uses the heat of the resistance wire to atomize the electronic cigarette liquid. Because a certain amount of the electronic cigarette liquid is atomized, it is required to generate an instantaneous high atomization temperature, such as general electrons. The atomization temperature of the liquid smoke is required to reach between 250 and 450 degrees Celsius. This requires the heating wire to work at a relatively high power in a short period of time. The general electronic aerosolizing device is arranged by the electric current that has been adjusted and controlled to flow through the heating wire to generate heat. When the button is pressed during smoking, the power is turned on. When the battery is not sucked, the power can be temporarily turned off. However, after multiple times of smoking, the power needs to be turned on every time the power is applied, and each time the power is turned on, heat is generated, which may eventually cause fog. The temperature of the heating wire is too high. Although the higher temperature is advantageous for the atomization effect, the negative effect is also very large. For example, if the temperature of the heating wire is too high, the temperature of the generated smoke will be too high, it will be hot, sometimes it will feel hot, and even burn the user; in addition, because the temperature of the atomizing heating wire is too high, it will cause it as an electronic cigarette. The oil-conducting fiber rope of the liquid carrier is coked at a high temperature, and the oil guiding effect is lost, resulting in damage of the atomizing core; and the atomization temperature of the electronic cigarette liquid is too high when the atomizing temperature is too high, which may cause uncertainty, for example, pre-production Unexpected harmful substances, etc.

Automatic control of the heating temperature, which is already very common in industrial applications, enables precise control of the heating temperature over a constant temperature range. However, since the electronic cigarette product belongs to a miniaturized electronic device, the volume of the electronic aerosol core is small, and it is quite difficult to add an ordinary temperature control device. It is also difficult to achieve with general industrial heating control methods.

The present invention is directed to the above-mentioned prior art defects, inventing a miniaturized electronic aerosolization temperature control method, and simultaneously designing a temperature control circuit that can be used on an atomization core of an electronic cigarette product.

Summary of the invention

One of the objects of the present invention is to provide a temperature control method for an electronic aerosolizing device that can effectively and accurately control the atomization temperature of the electronic cigarette to overcome the deficiencies of the prior art.

Another object of the present invention is to provide an electronic aerosolization heating temperature control circuit to implement the above method.

A third object of the present invention is to provide a temperature-controllable electronic aerosolizing core that can be controlled by the above method.

The technical solution of the present invention is implemented as follows:

The electronic aerosolization temperature adjustment control method of the present invention comprises the following steps:

Step 1: The small high stability, high sensitivity, high linear temperature measuring element is arranged near the heating body of the electronic cigarette atomizer to sense the temperature of the atomizer heating body;

Step 2: converting the temperature of the atomizer heating body of step 1 into a voltage drop parameter of the temperature measuring component;

Step 3: Compare the voltage drop of step 2 with a preset reference voltage to generate a comparison value;

Step 4: The comparison value obtained in step 3 is transmitted to the atomizer heating power control circuit. When the comparison value of step 3 is a negative value, the control circuit does not output the control signal, and the heating circuit continues to operate; when the comparison value is zero, Sending a control signal to reduce the heating power; when the comparison value is greater than zero, issuing a control signal to turn off the heating power;

Step 5: Control the atomization temperature by turning off the heating power or reducing the heating power.

By adjusting the different preset reference voltages of step 3, the required control can be realized. Thermal temperature adjustment, such as 250 degrees Celsius, 280 degrees Celsius or 300 degrees Celsius.

The small high stability, high sensitivity, high linearity temperature measuring element described above is a PT100 platinum thermistor.

Further, the step 1 further includes a temperature compensation test, and the temperature of the sensing point and the temperature of the atomizer heating body itself are subjected to actual measurement to give necessary numerical compensation. It is compensated to compensate for the temperature difference between the detection point temperature and the heating body itself.

Further, the temperature parameter in the step 2 is converted into a voltage drop component of the temperature measuring component, and the constant current power source is used to supply the temperature measuring component, and the voltage drop across the thermistor is collected. Since the constant current source is used for power supply, when the resistance value of the temperature measuring element changes with temperature, the voltage drop across the two ends will change linearly, and the output voltage drop parameter can be used to indirectly indicate the temperature.

Further, the step 3 further includes a process of setting a reference voltage in advance, and according to the actual measurement and calculation, obtaining a one-to-one correspondence relationship between the temperature of the atomizer heating body and the voltage drop parameter converted by the temperature measuring component, each voltage The drop data is the reference voltage drop for the corresponding heating temperature. The reference voltage value is calibrated by the actual measurement, and can directly correspond to the corresponding temperature. The temperature can be used to display the temperature, and the temperature controlled by the heating body can be preset as a control parameter.

The comparison value in the step 4 is processed separately in three cases. When the comparison value is negative, it belongs to the normal heating range; when the comparison value is zero, it belongs to the reduced heating power range; when the comparison value is greater than zero, it belongs to the stop heating range. Since the temperature measuring element has a linear relationship with temperature, the temperature parameter voltage drop value is less than the reference voltage value, indicating that the heating body has not reached the heating temperature, and heating needs to be continued, the power control circuit does not operate, and the power supply is continued to be heated; When the parameter voltage drop is equal to the reference voltage value, it indicates that the temperature to be controlled has been reached, and the heating power needs to be reduced. When the temperature parameter voltage drop value is greater than the reference voltage, it indicates that the set heating temperature has been exceeded, the heating should be stopped, and the power supply should be turned off.

detailed description

The invention will be further described in detail below with reference to the drawings and specific embodiments.

As shown in FIG. 1, the electronic aerosolization temperature control method of the present invention needs to be implemented by the following steps.

Step S1: setting a small high-linearity thermistor in the vicinity of the electronic aerosolization heating device to detect the temperature of the atomizer heating body.

The use of small, high-stability, high-sensitivity, high-linear temperature measuring elements is due to the fact that the atomizer itself is very small in volume and volume. Since the electronic cigarette itself is small in volume, it requires a high heating temperature, and it is also instantaneously heated, so the addition of the atomizer heating device is required. The thermal power is relatively large. Temperature-sensitive devices used to control the temperature of the heating device are also devices that require miniaturization and high linearity. For example, using a PT100 platinum thermistor device, the device can be made smaller, up to the millimeter level, and the linearity of the PT100 platinum thermistor. The range is -200 - 650 degrees Celsius, fully able to control the heating temperature of the electronic cigarette atomizer. In the specific setting, the PT100 needs to be placed as close as possible to the heating body to more accurately and quickly sense the temperature of the heating body.

However, it is impossible to intimately approach or even close to the heating body in actual use. In particular, in an electronic cigarette atomizer that uses electric heating of a conductor heating wire, the energized components need to be insulated from each other, so a certain distance must be required. The closest and no contact with each other is the principle. In the temperature control of the electronic cigarette atomizer of the present invention, the ceramic insulating frame can be isolated between the electronic aerosolizing heating wire and the PT100, and the insulating frame is used in order to receive heat radiation well. In addition, in the electronic cigarette atomizer, the PT100 can also be disposed in the inner space of the spiral of the atomizing heating wire, or even in the oil guiding rope disposed in the spiral of the atomizing heating wire, so that it is easier to make the sensed temperature close to heating. Body temperature.

However, although the thermistor cannot be infinitely close to the heating body, since the thermistor operates in a linear range, the necessary temperature compensation can be performed by actual measurement after determining the same type of heating body, the same type of thermistor, and the mutual positional relationship. Achieve precise control.

Therefore, it is necessary to use a small high stability, high sensitivity, high linear temperature measuring element to detect and control the electronic aerosolization temperature.

Step S2: converting the atomizer heating body temperature parameter to a voltage drop parameter of the temperature measuring element.

The characteristic of the temperature measuring element is that the resistance value changes linearly with the change of temperature, thus The temperature parameter detected by the temperature measuring element is generally expressed by the resistance parameter, but the measurement of the resistance parameter needs to be achieved by using the current. Therefore, the resistance is actually measured by measuring the current at a certain voltage or the voltage drop under a certain current condition. It is therefore necessary to convert the resistance parameter into a current or voltage parameter to be measured and represented.

The conversion of the temperature parameter in this step is to convert the resistance value of the temperature measuring element at a specific temperature into a voltage drop parameter, and use the voltage drop parameter to express the corresponding heating body temperature.

It is necessary to pay special attention to the fact that when the voltage drop is used as the measured value, it is necessary to set the constant current source. Only after the constant current source is set, the voltage drop and the resistance are linear under the condition of R=U/I. Only has the value of measurement. For the same reason, when it is necessary to express the measured temperature by current, it is necessary to set a stable voltage source. Since the invention controls and adjusts the atomization heating temperature of the electronic cigarette, it is not only a measurement problem, but also needs to compare and control the measurement parameters, and the voltage drop value detection is relatively simple and convenient. Of course, it is also within the scope of protection of the present invention to implement the method of measuring current.

Step S3: comparing the voltage drop parameter with a preset reference voltage drop parameter to generate a comparison value.

In order to achieve temperature control, it is necessary to set a predetermined temperature so that the temperature of the heating body fluctuates within a certain range above and below the preset temperature, which is the purpose of temperature control. In this step, the voltage drop value at both ends of the temperature measuring component is used as a comparison parameter, and compared with a preset voltage representing a certain temperature, by comparing the voltage drop parameter and the preset voltage, three different comparison results are generated. That is equal to, greater than or less than.

In order to obtain this comparison value, it is necessary to preset a reference voltage value corresponding to the control temperature. Therefore, in step 3, the step of setting the reference voltage value in advance is required. Pre The step of setting the voltage value is as shown in FIG. 2.

Step S01: A small temperature measuring element with a linear change in resistance within the atomization temperature range is used as the heat sensitive device.

In order to ensure the trueness and stability of the voltage value corresponding to the preset temperature, the same or the same thermistor device is used for the actual measurement and verification at the preset temperature and voltage value, and the temperature compensation is completed at the same time. This embodiment continues to use the same PT100 device as the heat-sensitive device, and its setting position is also the same as that of the atomizer itself.

Step S02: The thermistor is set at a specific position and a certain distance near the atomizer heating device.

This step further determines the position and distance between the temperature measuring element and the atomizing heating device, and must be consistent with the actual atomizer position and distance for reference value. In fact, it is equivalent to doing a blank test to calibrate the data.

Step S03: After the measured voltage drop parameter of different temperatures when a certain constant current source passes, the one-to-one correspondence relationship between the measured voltage drop parameter and the atomizer heating temperature is established.

That is, the corresponding relationship between the measured calibration temperature and the voltage drop value is performed. When the constant current source is turned on, the constant current source also ensures the consistency with the constant current source current in the actual electronic cigarette atomizer. By measuring the temperature of the atomizer heating body itself and the measured voltage drop across the temperature measuring element, a data table can be obtained, and the corresponding temperature and voltage value can be obtained under a certain current condition and a certain distance of a certain position. table.

Step S04: Calling a voltage drop parameter corresponding to a certain temperature as a reference voltage, and setting a temperature corresponding to the reference voltage to be a control heating temperature.

According to the corresponding data table obtained above, when we need to use some kind of electron In the case of the liquid smoke, a suitable temperature is determined, and the voltage drop corresponding to the temperature is set as the control reference voltage. That is, the corresponding temperature of the set reference voltage can be used as the control temperature.

After the pre-setting process of the reference voltage described above, the reference voltage number is determined, and the voltage drop detected from the temperature measuring element near the atomizer can be compared, that is, step S3.

Step S4: The obtained comparison value is transmitted to the heating power control circuit, and the control circuit outputs a different signal according to the comparison value.

Three different results are produced by voltage comparison, which are less than, that is, the result is negative; equal to, the result is zero; if greater than the result is positive. These three different results are input to the heating power control circuit, which produces three different results depending on the pre-set of the control circuit.

Step S5: The step is divided into three cases, which are respectively less than the result is negative, indicating that the heating temperature has not reached the set value, and the heating power control circuit works normally, and continues to heat up; The heating temperature has reached the set temperature, when the heating power is reduced; if the result is positive, it indicates that the set temperature has passed, and the control turns off the power of the heating device.

As shown in FIG. 5, in order to implement the above method of the present invention, a temperature-adjustable electronic cigarette atomizer structure is designed.

The temperature measuring element 1 uses a PT100 platinum thermal resistance, and the product has a length, a width and a height of 6 mm, a width of 2 mm and a height of 0.6 mm, and can be applied to an 8 mm diameter atomizing core casing of an electronic cigarette atomizer. Since the heating wire 4 and the temperature measuring element 1 are both disposed on the insulating frame 7, and the electrode terminal plate 12 of the atomizer is generally disposed at the bottom of the atomizing core casing 8, there is still a distance to reach the terminal block 11, so it is required For the heating wire 4 and the temperature measuring element 1, a heat-resistant, oil-resistant, and low-resistance wire pin is provided to facilitate connection with the terminal. The pin wires used in the present embodiment are nickel wires 3 and 5, which satisfy the above requirements. At the same time, in order to realize the function of the electronic cigarette, the oil guiding hole 9 and the vent hole 10 are also disposed on the atomizing core casing 8.

When the experimental data is obtained, the above components can be assembled, assembled into a complete atomizing core, installed in the atomizer, and an additional standard temperature measuring mechanism is arranged in the heating wire. When the experimental data is calibrated, the constant temperature power supply is turned on for the temperature measuring component, and the voltage drop data at both ends of the thermistor is read during the heating process, and the temperature measured by the standard temperature measuring mechanism is corresponding to the voltage drop across the temperature measuring component.

According to the data in the above table, if the standard curve is shown in Figure 6, the standard curve can guide the millivolts of the voltage drop corresponding to any temperature within a certain range. Further, the temperature of the heating is adjusted by the setting of the millivolt number.
