Technical Field

The present invention relates to temperature calibration systems, and particularly to an automatic temperature calibration system and method for a non-combustion electronic cigarette.

Background

Currently, smokers mainly use a tobacco ignition method to smoke, and the local temperature generated by the tobacco ignition can exceed 1000 ℃. Under the high temperature environment, tobacco can generate a plurality of harmful substances, and for smokers, the really needed components are saline alkali and nicotine in the tobacco, and the two substances can be produced from the tobacco without high temperature. Therefore, many new non-burning electronic cigarettes are available in the market, which bake tobacco to bake saline and alkaline and nicotine in the tobacco, and the temperature is far lower than the burning temperature of the tobacco (generally 200-. However, such electronic cigarettes have high requirements on temperature control, harmful substances are generated when the temperature is too high, and the electronic cigarettes are small in size or even do not produce smoke when the temperature is too low, so that temperature calibration needs to be performed when the electronic cigarettes leave a factory to ensure the temperature accuracy of each piece of equipment.

At present, most manufacturers adopt an artificial mode to calibrate the temperature, the cost is high, the artificial mode is easy to make mistakes, and meanwhile, in the calibration process, a temperature measuring probe needs to be stretched into a smoke tube, so that the smoke tube can be scalded accidentally.

Based on this, this application has proposed a non-burning electron cigarette automatic temperature calibration system and method.

As shown in fig. 3 to 4, an embodiment of the present invention further provides an automatic temperature calibration method for a non-combustion electronic cigarette, including the following steps:

In practical application, the smoking set to be calibrated is well connected with the temperature measurement module (the communication protocol connected here, and the upper computer can be compatible with two modes of HID and serial ports). After the connection is finished, the upper computer acquires the temperature data of the temperature measurement module in real time, and distributes the temperature of each channel to each smoking set to be calibrated according to the number of the sections of the smoking set to be calibrated (the distribution mode is that if the upper computer is a single-section device, the channel 1 corresponds to the first section temperature of the smoking set 1 to be calibrated, the channel 2 corresponds to the first section temperature … of the smoking set 2 to be calibrated, if the upper computer is a two-section device, the temperature of the channel 1 corresponds to the first section temperature of the smoking set 1 to be calibrated, the temperature of the channel 2 corresponds to the second section temperature of the smoking set 1 to be calibrated, the temperature of the channel 3 corresponds to the first section temperature of the smoking set 2 to be calibrated, the channel 4 corresponds to the second section … of the smoking set 2 to be calibrated, if the upper computer is a three-section device, the temperature of the channel 1 corresponds to the first section of the smoking set 1 to be calibrated, the temperature of the channel 2 corresponds to the second section of the smoking set 1 to be calibrated, the channel, channel 5 corresponds to the second section of smoking article 2 to be calibrated and channel 6 corresponds to the third section … of smoking article 2 to be calibrated).

The upper computer stores the collected temperature information, after the heating of the smoking set to be calibrated is completed, the average value of each section is calculated, the average value is compared with a target value in a preset temperature curve, finally, the difference value of the average value and the target value is sent to the smoking set calibration module, and the smoking set calibration module completes the temperature calibration of the smoking set to be calibrated according to the difference value.

In practical application, if the temperature difference is within 5 ℃, calibration is not needed and is directly completed, and the upper computer prompts a user and the temperature calibration is completed; otherwise, after the calibration is completed, the upper computer automatically starts the second temperature measurement and calibration, and the calibration process is the same as the first time.

After the second temperature measurement is completed, if the temperature difference is still greater than 5 ℃, the upper computer reports an error and prompts a user that the temperature calibration of the equipment fails.

In the temperature measurement process, at any time point, if the difference between the real-time temperature and the target temperature is more than 30 ℃, the equipment is abnormal, the equipment can be damaged if the real-time temperature and the target temperature are heated for a long time, the upper computer stops the temperature measurement of the equipment, and an alarm is given to prompt a user that the calibration fails.

In addition, in the embodiment of the present invention, the upper computer may automatically read the preset value parameter from the device, and may also manually set the preset value parameter, and if the user manually sets the preset value parameter (the preset value parameter may be saved as a file, and sent to another person, and the preset value parameter in the file is read), the upper computer may skip the step of reading the preset value of the device.
