[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] In one embodiment, Figure 1 As shown, Figure 1 A structural schematic diagram of a heating without burning appliance provided in an embodiment of the present application; the present application provides a heating without burning appliance 110, the heating without burning appliance 110 may include a main control chip 120 and a modularized heating element 130, and the heating element 130 is detachably connected to the main control chip 120.

[0034] The heating element 130 is provided with a storage chip, and the storage chip stores the calibration information and the temperature curve of the heating element 130 .

[0035] When the heating element 130 is connected to the main control chip 120 , the main control chip 120 reads the calibration information and the temperature curve in the storage chip, and heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve.

[0036] In this embodiment, Figure 1 As shown, the heating non-combustion device 110 of the present application includes but is not limited to a main control chip 120 and a modularized heating element 130. The heating element 130 and the main control chip 120 are detachably connected, so that the present application can replace different models of heating elements 130 according to actual needs, and the main control chip 120 can perform heating work according to the relevant information stored in the storage chip of the heating element 130.

[0037] Specifically, a storage chip is provided in the heating element 130 of the present application. The storage chip can be built into the heating element 130 through a main board, and the main board and the heating element 130 are connected through a heat insulation structure. This can prevent the storage chip from being damaged due to excessive temperature during the heating process of the heating element 130 and extend the service life of the storage chip.

[0038] Furthermore, the storage chip of the present application stores the calibration information and temperature curve of the heating element 130, and the calibration information includes but is not limited to the initial temperature, initial resistance and resistance temperature coefficient of the heating element 130. In this way, after the heating element 130 is connected to the main control chip 120, the main control chip 120 can read the calibration information and temperature curve stored in the storage chip of the heating element 130, and heat and control the temperature of the heating element 130 according to the calibration information and temperature curve.

[0039] Among them, when the present application connects the heating element 130 with the main control chip 120, the pins of the main control chip 120 can be connected to the pins of the storage chip in the heating element 130. This process can be connected through IIC pins, SPI connections, or single-line communication pins. The specific setting can be based on the interface type of the storage chip, and no restriction is made here. At the same time, the main control chip 120 can also be connected to the GND and power supply pins of the heating element 130 to power the heating element 130 while controlling its temperature.

[0040] In the above embodiment, the heating-not-burning device 110 includes a main control chip 120 and a modularized heating element 130, and the heating element 130 is detachably connected to the main control chip 120, so that different cigarettes can be smoked by switching different types of heating elements 130, and the heating element 130 can be replaced separately when it is damaged, thereby effectively saving resources and avoiding environmental pollution. In addition, a storage chip is provided in the heating element 130 of the present application, and the calibration information and temperature curve of the heating element 130 are stored in the storage chip. When the heating element 130 is connected to the main control chip 120, the main control chip 120 can read the calibration information and temperature curve in the storage chip, and heat and control the temperature of the heating element 130 according to the calibration information and temperature curve, thereby realizing heating work according to different types of heating elements 130, thereby providing users with a variety of smoking experiences.

[0041] In one embodiment, the heating element 130 is connected to the main control chip 120 by means of a striker.

[0042] In this embodiment, the heating element 130 and the main control chip 120 can be connected by means of a striker. The striker connection is a mechanical connection method, and the usual implementation method is: corresponding strikers and interface structures are designed on the heating element 130 and the main control chip 120, respectively. The striker is generally a small metal needle-like structure, which can be inserted into a specific interface on the main control chip 120. This connection method has good stability and can ensure that the heating element 130 is relatively fixed inside the heating non-combustion device 110. For example, when the user moves the device during daily use or is slightly bumped, the striker connection can prevent the heating element 130 from easily shifting.

[0043] In one embodiment, the heating element 130 is connected to the main control chip 120 by magnetic attraction.

[0044] In this embodiment, the heating element 130 and the main control chip 120 can also be connected by magnetic attraction. Magnetic connection uses the attraction of magnetic materials to achieve the connection between the heating element 130 and the main control chip 120. The specific implementation method can be: magnets or magnetic materials are respectively installed on the contact surfaces of the heating element 130 and the main control chip 120. When the heating element 130 is close to the main control chip 120, the two will automatically be adsorbed together due to the magnetic force.

[0045] The advantage of using magnetic connection in this application is that it is convenient and quick, and the user can simply operate when installing or removing the heating element 130, without complicated plugging and unplugging actions. In addition, the magnetic connection can make the contact between the heating element 130 and the main control chip 120 closer, which is conducive to power transmission and heat conduction.

[0046] In one embodiment, the heating element 130 and the main control chip 120 are connected by a striker and a magnetic attraction.

[0047] In this embodiment, the heating element 130 and the main control chip 120 can also be connected by means of a striker and a magnetic attraction. The combination of magnetic attraction and striker connection can greatly improve the convenience of users replacing the heating element 130. For the heating non-combustion device 110, the heating element 130 may need to be replaced or cleaned regularly. The magnetic attraction feature allows the user to easily remove the heating element 130 from the main body of the smoking device, and the striker ensures that the heating element 130 will not fall off accidentally during use. For example, when traveling, if the heating element 130 fails, the user can quickly replace the heating element 130 without affecting normal use.

[0048] Moreover, during use, this connection method can provide stable power transmission and good heat conduction. The striker ensures the physical stability of the connection, so that the electrical connection between the heating element 130 and the main control chip 120 is tight, reducing the situation of poor contact. Magnetic attraction further enhances the tightness of the connection, which is conducive to the efficient conduction of heat from the heating element 130 to other parts of the appliance, thereby ensuring that the heated object can be heated evenly. In addition, since the heating element 130 and the main control chip 120 are tightly connected, it can also reduce safety hazards such as short circuit or overheating caused by loose connection.

[0049] In one embodiment, the main control chip 120 heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve, which may include:

[0050] After the main control chip 120 reads the current resistance value of the heating element 130, it determines the current temperature of the heating element 130 according to the calibration information and the current resistance value, and when it is determined that the current temperature is within a preset temperature range, it heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve.

[0051] In this embodiment, when the main control chip 120 heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve, it can first read the current resistance value of the heating element 130, and then determine the current temperature of the heating element 130 according to the calibration information and the current resistance value. Then, the present application can determine whether the current temperature of the heating element 130 is within a preset temperature range. If so, the heating element 130 can be heated and controlled according to the calibration information and the temperature curve when the heating element 130 is in good contact, thereby providing the user with a safe and stable suction experience.

[0052] In one embodiment, the calibration information may include the initial temperature, initial resistance and resistance temperature coefficient of the heating element 130 .

[0053] The main control chip 120 determines the current temperature of the heating element 130 according to the calibration information and the current resistance value, which may include:

[0054] The main control chip 120 calculates the current temperature of the heating element 130 according to the initial temperature, the initial resistance value, the resistance temperature coefficient, and the current resistance value.

[0055] In this embodiment, the calibration information stored in the storage chip includes but is not limited to the initial temperature, initial resistance and resistance temperature coefficient of the heating element 130. After reading the calibration information, the main control chip 120 can detect the current resistance of the heating element 130 and calculate the current temperature of the heating element 130 based on the calibration information and the current resistance.

[0056] In a specific implementation, when calculating the current temperature of the heating element 130 according to the calibration information and the current resistance value, the present application may use the following formula for calculation:

[0057] T = ((R-R0)*TCR) / R + T0

[0058] In the above formula, T is the current temperature of the heating element 130 , T0 is the initial temperature of the heating element 130 , R0 is the initial resistance of the heating element 130 , R is the current resistance of the heating element 130 , and TCR is the resistance temperature coefficient of the heating element 130 .

[0059] In one embodiment, before determining that the current temperature is within a preset temperature range, the main control chip 120 may further include:

[0060] The main control chip 120 obtains the current ambient temperature, and after subtracting the current ambient temperature from the current temperature, determines whether the difference after the difference is within a preset difference range, so as to determine whether the current temperature is within the preset temperature range.

[0061] In this embodiment, before determining that the current temperature is within the preset temperature range, the main control chip 120 can first obtain the current ambient temperature, and after subtracting the current ambient temperature from the current temperature, determine whether the current temperature is within the preset temperature range based on whether the difference after the difference is within the preset difference range. This can not only improve the accuracy of the judgment result, but also determine whether the connection of the heating element 130 is abnormal.

[0062] In one embodiment, the main control chip 120 heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve, which may include:

[0063] The main control chip 120 heats the heating element 130 according to the temperature curve, and controls the temperature of the heating element 130 according to the calibration information.

[0064] In this embodiment, when the main control chip 120 heats and controls the temperature of the heating element 130 according to the calibration information and the temperature curve, the heating element 130 may be heated by the temperature curve first and then the temperature of the heating element 130 may be controlled according to the calibration information.

[0065] Among them, in the process of controlling the temperature of the heating element 130 according to the calibration information, the present application can detect the current resistance value of the heating element 130, and calculate the current temperature of the heating element 130 according to the calibration information and the current resistance value. When calculating the current temperature of the heating element 130, the above-mentioned calculation formula can be used for calculation, and after calculating the current temperature, it is compared with the corresponding temperature value in the temperature curve, and then the temperature is controlled according to the comparison result. If the current temperature is higher than the temperature value in the temperature curve, the temperature of the heating element 130 is lowered. If the current temperature is lower than the temperature value in the temperature curve, the temperature of the heating element 130 is increased to make it meet the temperature value in the temperature curve.

[0066] In one embodiment, the main control chip 120 can also be used for:

[0067] When it is determined that the current temperature is not within the preset temperature range, the device is controlled to vibrate and flash a light to indicate that the heating element 130 is abnormal.

[0068] In this embodiment, when the main control chip 120 determines that the current temperature is not within the preset temperature range, it means that the main control chip 120 is not connected to the heating element 130 or the contact is poor. At this time, the main control chip 120 can control the device to oscillate and flash to prompt the user that the heating element 130 is abnormal, thereby reducing safety hazards.

[0069] In one embodiment, the main control chip 120 can also be used for:

[0070] When the calibration information and / or the temperature curve is not read, the device is controlled to vibrate and flash the light to indicate that the heating element 130 is abnormal.

[0071] In this embodiment, the main control chip 120 can not only control the device to oscillate and flash when it is determined that the current temperature is not within the preset temperature range, but also control the device to oscillate and flash when the calibration information and / or temperature curve is not read, so as to prompt the user that the heating body 130 is abnormal, thereby reducing safety hazards.

[0072] In one embodiment, the present application also provides a heating element 130, which, after being modularized, can be detachably connected to the main control chip 120 in the heating without burning device 110 in any of the above embodiments, so that different cigarettes can be smoked by switching different models of heating elements 130, and the heating element 130 can be replaced separately when it is damaged, thereby effectively saving resources and avoiding environmental pollution.

[0073] In one embodiment, Figure 2 As shown, Figure 2 A flow chart of a heating control method provided in an embodiment of the present application; the present application also provides a heating control method, which is applied to the main control chip 120 in the heating without burning appliance 110 in any one of the above embodiments, and the method may include:
