[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of electronics, in particular to an electronic cigarette and a temperature control method thereof.

[ background of the invention ]

An electronic cigarette is an electronic product that simulates a cigarette and has the same or similar appearance, smoke, taste and sensation as a cigarette. It changes nicotine into steam by means of atomization and the like, and then is provided for users to suck. Conventional electronic cigarettes atomize nicotine by heating. Different temperatures can cause the electronic cigarette to generate different tastes and smoke amounts, so that the control of the temperature in the electronic cigarette is particularly important.

However, conventional electronic cigarettes use an oversampled temperature sensor resistance and then calculate the target temperature as a function of resistance and temperature. The functional relationship (1) is as follows:

R1＝R0*(1+K)*ΔT； (1)

wherein R1 is the resistance value of the temperature sensor at the target temperature;

r0 is the resistance value of the temperature sensor at 25 ℃;

k is the temperature coefficient of the temperature sensor;

Δ T is the difference between the target temperature minus 25 ℃, i.e., the temperature difference;

therefore, in the conventional electronic cigarette, the target temperature of the heating device is calculated, is not measured, and is an open-loop temperature control method, so that the error is large. Meanwhile, because factors causing errors are various and the individual differences of the errors generated in different products are large, the factors are not considered in the control method, and therefore, the heating accuracy of the products is difficult to control in batch production.

[ summary of the invention ]

The technical problem to be solved by the invention is as follows: the electronic cigarette and the temperature control method thereof can accurately control the heating temperature of the target.

In order to solve the technical problems, the invention provides the following technical scheme:

an electronic cigarette, comprising: the temperature control device comprises a power supply unit, a heating component, a temperature feedback component and a control unit; the power supply unit is used for providing working voltage for the control unit and the heating component; the heating component is used for heating substances in the electronic cigarette by heating and providing actual heating temperature; the temperature feedback component is used for providing feedback parameters for the controller according to the actual heating temperature of the heating component; the control unit is used for controlling the heating power of the heating component according to the feedback parameter provided by the temperature feedback component, the preset target temperature and a prestored temperature control mapping table so that the actual heating temperature is consistent with the preset target temperature; the temperature control mapping table is a one-to-one mapping table between the actual heating temperature of the heating component and the feedback parameters provided by the temperature feedback component.

On the other hand, the embodiment of the invention also provides an electronic cigarette temperature control method, which comprises the following steps: step 220, reading feedback parameters of the temperature feedback unit; step 230, obtaining a corresponding actual heating temperature in a pre-stored temperature control mapping table according to the feedback parameter; the temperature control mapping table is a mapping table in one-to-one correspondence between the actual heating temperature of the heating component and the feedback parameters provided by the temperature feedback component; step 240, comparing the actual heating temperature with a preset target temperature, and controlling the heating power of the heating component according to the comparison result until the actual heating temperature is consistent with the preset target temperature.

The beneficial effect of the present invention is that the actually measured actual heating temperature of the heating component 23 and the feedback parameter to the temperature feedback unit 24 are in one-to-one correspondence by using the pre-stored temperature control mapping table. The control unit 21 reads the feedback parameter of the temperature feedback unit 24, obtains the corresponding actual heating temperature in the temperature control mapping table according to the parameter, compares the actual heating temperature with the preset target temperature, and controls the power of the heating element according to the comparison result, thereby finally achieving the result of controlling the actual heating temperature to be consistent with the target temperature. Therefore, the technical scheme provided by the embodiment of the invention forms closed-loop control on the actual heating temperature and provides an electronic cigarette product with higher temperature control accuracy.

[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an embodiment of an electronic cigarette according to the present invention is shown. This electron cigarette 20 includes: a power supply unit 21, a heat generating component 23, a temperature feedback component 24, and a control unit 21.

The power supply unit 21 is used for providing an operating voltage to the control unit 21 and the heating element 23. Which may include a rechargeable battery, the specific circuitry being familiar to those skilled in the art and not described in detail herein.

The heating component 23 is used for heating the substance in the electronic cigarette by heating and providing actual heating temperature. The actual heating temperature is the actual temperature of the heating element 23 during operation.

The temperature feedback component 24 is used for providing feedback parameters for the controller 21 according to the actual heating temperature of the heating component 23. The temperature feedback assembly 24 may be a temperature sensor, and the feedback parameter is the current resistance of the temperature sensor.

The control unit 21 is configured to control the heating power of the heating component 23 according to the feedback parameter provided by the temperature feedback component 24, a preset target temperature and a pre-stored temperature control mapping table, so that the actual heating temperature is consistent with the preset target temperature; the temperature control map is a one-to-one correspondence map between the actual heating temperature of the heating element 23 and the feedback parameter provided by the temperature feedback element 24. The actual heating temperature and the corresponding feedback parameters are measured data, and are not data obtained by calculation according to a formula. The actual heating temperature can be detected by external detection equipment for the part of the electronic cigarette, which needs to control the heating temperature; the feedback parameters are read by the control unit 21.

The temperature control mapping table may be stored in the control unit 21, or may be stored in an independent storage medium in the electronic cigarette, and may be not lost when power is turned off or may be lost when power is turned off, which is a technique familiar to those skilled in the art and will not be described herein again.

Specifically, when the actual heating temperature obtained according to the feedback parameter and the temperature control mapping table is lower than the pre-stored target temperature, the control unit 21 increases the heating power of the heating element 23; otherwise, the control unit 21 reduces the heating power of the heating element 23.

Specifically, the manner for the control unit 21 to increase or decrease the heating power of the heating element 23 may be: without the electronic switch 22, the control unit 21 adjusts the duty ratio of the control signal output to the heating element 23 according to the feedback parameter provided by the temperature feedback element 24, the preset target temperature and the pre-stored temperature control mapping table, so as to adjust the actual heating temperature to be consistent with the target temperature.

Specifically, the electronic cigarette may further include: an electronic switch 22.

The electronic switch 22 is used for controlling the on and off of the circuit between the power supply unit 21 and the heating element 23. That is, when the electronic switch 22 is turned on, the circuit is turned on, and the power supply unit 21 supplies power to the heating element 23, so that the heating element 23 generates heat; when the electronic switch 22 is turned off, the circuit is opened, the power supply unit 21 stops supplying power to the heating element 23, and the temperature of the heating element 23 gradually decreases. The electronic switch 22 may employ specific components such as a Transistor, a MOSFET (metal oxide semiconductor Field Effect Transistor), an IGBT (Insulated Gate Bipolar Transistor), an optocoupler relay, and a relay, and specific circuit structures thereof are familiar to those skilled in the art, and are not described herein.

The way for the control unit 21 to raise or lower the heating power of the heating component 23 may be: the control unit 21 controls the electronic switch 22 to be turned on or off according to the feedback parameter provided by the temperature feedback component 24, the preset target temperature and the pre-stored temperature control mapping table, so as to adjust the actual heating temperature to be consistent with the target temperature.

Specifically, when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is lower than the target temperature, the control unit 21 controls the electronic switch 22 to be turned on, and the power supply unit 21 supplies power to the heating element 23 to increase the temperature thereof; when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is higher than the target temperature, the control unit 21 controls the electronic switch 22 to be turned off, the power supply unit 21 stops supplying power to the heating element 23, and the temperature of the heating element 23 is gradually decreased.

Optimally, when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is equal to the target temperature, the designer can design whether the control unit 21 controls the electronic switch 22 to be turned on or off according to the requirement because the value is a critical value.

The control unit 21 may adopt a control chip familiar to those skilled in the art of electronic cigarette products, including but not limited to an mcu (micro Controller unit) microcontroller unit, an mpu (micro Processor unit) microprocessor unit, and a dsp (digital Signal processing) digital Signal processing, which are not described herein.

Due to various factors, the temperature calculated by the control unit 21 according to the feedback parameters provided by the temperature feedback component 24 may deviate greatly from the actual heating temperature of the heating component 23. In the embodiment of the present invention, the actually measured actual heating temperature of the heating element 23 and the feedback parameter to the temperature feedback unit 24 are in one-to-one correspondence by using a pre-stored temperature control mapping table. During operation, the control unit 21 reads the feedback parameter of the temperature feedback unit 24, obtains the corresponding actual heating temperature from the temperature control mapping table according to the parameter, compares the actual heating temperature with the preset target temperature, and controls the heating power of the heating element 23 according to the comparison result, thereby finally achieving the result of controlling the actual heating temperature to be consistent with the target temperature. Therefore, the technical scheme provided by the embodiment of the invention forms closed-loop control on the actual heating temperature and provides an electronic cigarette product with higher temperature control accuracy.

Referring to fig. 2, a method for controlling the temperature of an electronic cigarette according to an embodiment of the present invention is described. The electronic cigarette temperature control method comprises the following steps:

step 230, obtaining a corresponding actual heating temperature in a pre-stored temperature control mapping table according to the feedback parameter; the temperature control mapping table is a one-to-one mapping table between the actual heating temperature of the heating element 23 and the feedback parameter provided by the temperature feedback element 24;

step 240, comparing the actual heating temperature with a preset target temperature, and controlling the heating power of the heating element 23 according to the comparison result until the actual heating temperature is consistent with the preset target temperature.

Specifically, the step 240 includes:

step 241, when the actual heating temperature obtained according to the feedback parameter and the temperature control mapping table is lower than the pre-stored target temperature, increasing the heating power of the heating component 23;

in step 242, when the actual heating temperature obtained according to the feedback parameter and the temperature control mapping table is higher than the pre-stored target temperature, the heating power of the heating element 23 is reduced.

Specifically, the step of "controlling the heating power of the heating element 23 according to the comparison result" may be:

according to the feedback parameter provided by the temperature feedback component 24, the preset target temperature and the pre-stored temperature control mapping table, the duty ratio of the control signal output to the heating component 23 is adjusted.

Specifically, the step of "controlling the heating power of the heating element 23 according to the comparison result" may be:

the electronic switch 22 is controlled to be turned on or off according to the feedback parameters provided by the temperature feedback component 24, the preset target temperature and a pre-stored temperature control mapping table.

Specifically, the step 240 includes:

241, controlling the electronic switch to be switched on when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is lower than the target temperature;

and 242, controlling the electronic switch to be turned off when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is higher than the target temperature.

Optimally, this step 240 further includes:

and 243, controlling the electronic switch 22 to be turned on or off when the corresponding actual heating temperature matched in the temperature control mapping table according to the feedback parameter is equal to the target temperature.

Further, the electronic cigarette temperature control method further comprises the following steps: and step 100, acquiring and storing the temperature control mapping table in advance. The step 100 specifically includes:

step 120, reading and recording a feedback parameter of a temperature feedback unit corresponding to the actual heating temperature by a control unit of the electronic cigarette;

In the embodiment of the present invention, the actually measured actual heating temperature of the heating element 23 and the feedback parameter to the temperature feedback unit 24 are in one-to-one correspondence by using the pre-stored temperature control mapping table. Therefore, the actual heating temperature of the heating component can be adjusted by detecting the change of the feedback parameter to form closed-loop temperature control, so that the actual heating temperature of the heating component can be accurately controlled to be below the preset target temperature. And a better use experience is provided for the user.
