Description

Technical Field

[0001] This invention relates to the field of heating control technology, specifically to a temperature calibration and detection method, device, heated non-combustible smoke appliance, and storage medium. Background Technology

[0002] To ensure the accuracy of temperature control of the heating element, existing heated non-combustible smoke appliances generally require temperature calibration. After temperature calibration, a second test is required to ensure product quality.

[0003] Existing calibration and testing methods typically involve placing the product under an infrared temperature detection device, controlling the heated non-combustible smoke appliance to heat according to a preset temperature curve, and detecting whether the temperature of the heating element of the heated non-combustible smoke appliance under infrared light is consistent with the set temperature curve.

[0004] During the product manufacturing process, high temperatures and time-consuming testing can significantly slow down production efficiency, resulting in low product output. Summary of the Invention

[0005] The main technical problem solved by this invention is the low detection efficiency of existing methods that use infrared temperature detection for temperature calibration.

[0006] According to the first aspect, one embodiment provides a temperature calibration detection method applied to a heated non-combustible smoke appliance, the heated non-combustible smoke appliance including a heating element for heating an aerosol generating matrix to generate an aerosol, the heating element having at least two heating zones;

[0007] The methods include:

[0008] The first heating zone on the heating element is heated to a first temperature, and the first heating zone can be any heating zone on the heating element.

[0009] After a preset time, the second temperature of other heating zones on the heating element, excluding the first heating zone, is detected.

[0010] Determine whether the second temperature of each heating zone is within the preset temperature range corresponding to each heating zone;

[0011] If so, the temperature calibration of the heating element is deemed qualified;

[0012] If not, the temperature calibration of the heating element is deemed unqualified.

[0013] According to a second aspect, one embodiment provides a temperature calibration and detection device applied to a heated non-combustible smoke appliance, comprising:

[0014] The heating control module is used to control the first heating zone on the heating element to heat to a first temperature. The first heating zone can be any heating zone on the heating element.

[0015] The detection module is used to detect the second temperature of other heating areas on the heating element besides the first heating area after a preset time.

[0016] The judgment module is used to determine whether the second temperature of each heating zone is within the preset temperature range corresponding to each heating zone.

[0017] If so, the temperature calibration of the heating element is deemed qualified;

[0018] If not, the temperature calibration of the heating element is deemed unqualified.

[0019] According to a third aspect, one embodiment provides a heating element for heating an aerosol-generating matrix to generate an aerosol and a temperature detection device as described in the second aspect; the heating element has at least two heating zones.

[0020] According to a fourth aspect, one embodiment provides a computer-readable storage medium storing a program that can be executed by a processor to implement the method as described in the first aspect.

[0021] According to the temperature calibration detection method, apparatus, heated non-combustible tobacco appliance, and storage medium of the above embodiments, by controlling the first heating zone of the heating element to heat to a first temperature and maintaining the heating for a preset time, the overall temperature transfer of the tobacco appliance reaches a steady state. Other heating zones, after being heated by the first heating zone, rise to a second temperature. If the temperature of the tobacco appliance passes the temperature test (the second temperature is within the preset temperature range), the tobacco appliance can achieve self-detection. Therefore, it is unnecessary to use external temperature detection equipment for temperature calibration qualification testing, improving detection efficiency. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] Existing heat-not-burn devices, such as heat-not-burn smoking appliances, generate smoke by heating an aerosol matrix, such as a cigarette stick. This process of smoke generation can also be called atomization. The quality of the smoke generation directly affects the user experience, such as the taste. The temperature control of the heating element affects the smoke generation effect; therefore, the heating element needs to be calibrated. Only smoking appliances that meet the calibration requirements after calibration can be considered qualified products.

[0032] Some existing types of heated non-combustible smoke appliances have a heating element 10 with at least two heating zones 11. By adjusting the temperature of each heating zone 11, different smoke effects can be provided.

[0033] The applicant's research found that, under certain verification conditions, the temperature calibration can be determined by detecting the temperature relationship between each heating zone 11, and the inspection can be completed through product self-inspection, without relying on external infrared detection equipment.

[0034] like Figures 1 to 3 As shown, this application embodiment provides a temperature calibration and detection device 20 and a heated non-combustible smoke appliance. Wherein, as... Figure 1 As shown, a heated non-combustible smoke appliance may include a heating element 10 and a temperature calibration and detection device 20. The heating element 10 is used to heat the aerosol generating matrix 30 to generate an aerosol, such as... Figure 3 As shown, the heating element 10 has at least two heating zones 11.

[0035] In one embodiment, the heating element 10 can be a cylindrical heating element or a tubular heating element, and the heating area 11 is disposed on the side wall of the heating element 10. For example, the heating element 10 can be a heating tube printed with circumferential thick film, and the aerosol generating matrix 30 is sleeved inside the heating tube.

[0036] like Figure 2 As shown, the temperature calibration and detection device 20 is applied to heated non-combustible smoke appliances and may include: a heating control module 21, a detection module 22, and a judgment module 23. Each of these modules may be a single functional module implemented using a processing chip, or multiple modules may be implemented using the same processing chip.

[0037] The heating control module 21 is used to control the first heating zone on the heating element 10 to heat to a first temperature. The first heating zone is any heating zone 11 on the heating element 10.

[0038] The detection module 22 is used to detect the second temperature of the other heating areas 11 on the heating element 10, excluding the first heating area, after a preset time.

[0039] The judgment module 23 is used to determine whether the second temperature of each heating zone 11 is within the preset temperature range corresponding to each heating zone 11; if yes, the temperature calibration of the heating element 10 is qualified; if no, the temperature calibration of the heating element 10 is unqualified.

[0040] The following describes the specific process of temperature calibration and testing using the temperature calibration and testing device 20, taking a heated non-combustible smoke appliance as an example. Figure 4 As shown, the temperature control method includes the following steps:

[0041] Step 0: Determine whether the heating element 10 has been calibrated according to the preset calibration rules.

[0042] The temperature control of the heating element 10 generally requires calibrating the relationship between the heating temperature and the input voltage / current. For example, when heating to 200℃ is required, the theoretical voltage is 10V and the current is 1A. However, manufacturing errors in the actual heating element 10 may result in an actual heating temperature of 190℃ or 200℃ when the input voltage is 10V and the current is 1A. When this temperature error exceeds the acceptable range, the heating element 10 needs to be calibrated. Temperature calibration of the heating element 10 is performed using preset calibration rules to ensure that the actual heating temperature of the heating element 10 more closely matches the theoretical heating temperature. However, whether the calibration is successful requires subsequent verification.

[0043] The specific calibration rules need to be set according to the type of heating element 10. For example, when the heating element 10 is a resistive heating element, temperature control can be achieved through a temperature coefficient of resistance (TCR). By obtaining the temperature coefficient of resistance of the heating element 10 and measuring its resistance, the current temperature of the heating element 10 can be calculated. In this case, the calibration of the heating element 10 can be performed by calibrating its temperature coefficient of resistance. When the heating element 10 uses other types of heating elements (such as electromagnetic heating), corresponding settings need to be made according to its heating type.

[0044] This application does not limit the specific calibration rules, but it is necessary to determine that the heating element 10 has been calibrated before proceeding with subsequent calibration qualification checks. For example, a calibrated smoking device can carry calibration information indicating whether the heating element 10 has been calibrated. In some embodiments, the calibration information can be a specific control signal. When the temperature calibration detection device 20 receives this specific control signal, it can determine that the heating element 10 has been calibrated and proceed to the next step of testing.

[0045] Step 1: Control the first heating zone on the heating element 10 to heat to the first temperature. The first heating zone is any heating zone 11 on the heating element 10.

[0046] In some embodiments, when any two heating zones 11 are respectively used as first heating zones, the first temperatures corresponding to the two heating zones 11 may be the same or different. For example, as Figure 3 As shown, when the upper heating area 11 is used as the first heating area, its first temperature can be 260℃; when the lower heating area 11 is used as the first heating area, its first temperature can be 260℃ or other temperatures.

[0047] In one embodiment, the heating element 10 can be a resistive heating element 10, and controlling the first heating area on the heating element 10 to heat to a first temperature can include:

[0048] Step 101: Detect the first resistance value of the first heating zone.

[0049] Step 102: Obtain the first preset resistance value corresponding to the preset temperature based on the temperature coefficient of resistance.

[0050] Step 103: When the first resistance value is equal to the first preset resistance value, control the resistance value of the heating element 10 to be maintained at the first preset resistance value.

[0051] For example, when the first temperature of the first heating zone is 260℃, the corresponding first preset resistance value is 10Ω. If the current first resistance value is detected to be 20Ω, the first heating zone is controlled to heat up, and the real-time first resistance value is continuously detected at preset time intervals until the first resistance value is 10Ω. At this point, it can be considered that the temperature of the first heating zone has reached 260℃.

[0052] Step 2: After a preset time, detect the second temperature of the other heating areas 11 on the heating element 10, excluding the first heating area.

[0053] In some embodiments, when the heating element 10 is a resistive heating element, the current temperature of the heating area 11 can be calculated by obtaining the temperature coefficient of resistance of the heating area 11 and measuring the resistance of the heating area 11. Of course, the temperature of the heating area can also be obtained directly by a temperature sensor or infrared detection.

[0054] In some embodiments, detecting a second temperature of the other heating zone 11 may include:

[0055] Step 201: Detect the second resistance value of other heating areas 11.

[0056] Step 202: Obtain the second temperature of other heating zones 11 based on the temperature coefficient of resistance and the second resistance value.

[0057] In some other embodiments, when the heating element 10 is a non-resistive heating element, the temperature can also be measured using a temperature sensor, such as an infrared or thermocouple.

[0058] Step 3: Determine whether the second temperature of each heating zone 11 is within the preset temperature range corresponding to each heating zone 11.

[0059] If so, the temperature calibration of heating element 10 is deemed qualified.

[0060] If not, the temperature calibration of heating element 10 is deemed unqualified.

[0061] For example, such as Figure 3As shown, when the upper heating zone 11 is used as the first heating zone, its first temperature can be 260℃, and the corresponding preset temperature range for the lower heating zone 11 can be 196℃-204℃. If the corresponding second temperature is 210℃, the temperature calibration of the heating element 10 is deemed unqualified; if the corresponding second temperature is 201℃, the temperature calibration of the heating element 10 is deemed qualified.

[0062] In one embodiment, the method may further include:

[0063] Step 001: Based on at least one of the following three factors—the structure and material of the heating element 10 and the positional relationship of each heating zone 11—establish a database that corresponds one-to-one with the preset temperature range of each of the other heating zones 11 for any first temperature value of any heating zone 11.

[0064] For example, simulations can be performed on simulation software to confirm the preset temperature range corresponding to other heating zones 11 when each heating zone 11 is the first heating zone.

[0065] For example, an experiment can be conducted using a smoking device that has been tested by an external temperature measuring device to determine the preset temperature range corresponding to the other heating zones 11 when each heating zone 11 is the first heating zone.

[0066] In other words, the aforementioned database can be obtained through various methods such as actual measurement, simulation, or calculation. Depending on the specific temperature control requirements of the smoking device or the product quality requirements, there are different preset temperature ranges. The smaller the range, the higher the requirements for the smoking device.

[0067] In one embodiment, after heating the first heating zone on the heating element 10 to a first temperature, the method may further include:

[0068] Step 104: Obtain the preset temperature range of each of the remaining heating zones corresponding to the first temperature of the first heating zone from the pre-stored database.

[0069] For example, such as Figure 3 As shown, when the upper heating zone 11 is used as the first heating zone, the first temperature is 260℃, corresponding to a preset temperature range of 196℃-204℃ for the lower heating zone 11. When the lower heating zone 11 is used as the first heating zone, the first temperature is 300℃, corresponding to a preset temperature range of 236℃-244℃ for the upper heating zone 11.

[0070] In one embodiment, after determining that the temperature calibration of the heating element 10 is unqualified if not, the method may further include:

[0071] Step 4: Perform a second temperature calibration on the heating element 10 according to the preset calibration rules.

[0072] Generate and execute the instruction to "control the first heating zone on the heating element 10 to heat to a preset temperature, wherein the first heating zone is any heating zone 11 on the heating element 10".

[0073] In other words, the calibrated heating element 10 cannot pass the test and needs to be calibrated again. After recalibrating according to the preset calibration rules, step 1 above is executed again to re-calibrate and test.

[0074] In some embodiments, such as Figure 5 As shown, if so, after determining that the temperature calibration of the heating element 10 is qualified, the method may include:

[0075] Step 5: Control another heating area 11 as the first heating area, generate and execute the instruction "control the first heating area on the heating element 10 to heat to a preset temperature, the first heating area is any heating area 11 on the heating element 10", and execute step 1 above again. This allows multiple heating areas 11 to be used as the first heating area for mutual inspection, which can further verify the calibration of the heating element 10.

[0076] In summary, this embodiment of the application controls the first heating zone of the heating element 10 to heat to a first temperature and maintains the heating for a preset time, after which the overall temperature transfer of the smoking device reaches a steady state. Other heating zones 11, heated by the first heating zone, rise to a second temperature. If the temperature of the smoking device passes the temperature test (the second temperature is within the preset temperature range), the smoking device can achieve self-testing. Therefore, it eliminates the need for external temperature detection equipment to test temperature calibration compliance, improving testing efficiency.

[0077] Furthermore, in some embodiments, after a re-inspection fails, a second calibration can be performed to achieve automatic recalibration and re-inspection, thereby improving testing efficiency.
