[0005] In a first aspect, the present invention provides a method for rapidly heating a hot air gun, the hot air gun comprising a heating wire and a fan, a controller being connected to the heating wire and the fan respectively, the method being applied to the controller, the method comprising:

[0006] The temperature value of the heating wire is obtained as the first target temperature value;

[0007] The first temperature ratio is obtained by dividing the first target temperature value by the preset set temperature.

[0008] The product of the first temperature ratio and the preset maximum power value is calculated as the output power of the fan, and the fan is controlled to output power at the specified output power.

[0009] After a preset first time interval, it is determined whether the temperature value of the heating wire has reached the set temperature;

[0010] If the temperature of the heating wire does not reach the set temperature, proceed to the step of obtaining the temperature of the heating wire as the first target temperature value.

[0014] After a preset second time interval, the temperature value of the heating wire is obtained as the second target temperature value;

[0015] Determine whether the second target temperature value is less than the set temperature;

[0016] If the second target temperature value is lower than the set temperature, reduce the output power of the fan.

[0017] A further technical solution is that reducing the output power of the fan includes:

[0018] Calculate the temperature difference between the temperature value of the heating wire and the second target temperature value;

[0019] Determine the target output power corresponding to the temperature difference from the preset temperature difference-power correspondence table;

[0020] Adjust the output power of the fan to the target output power.

[0021] A further technical solution is that, after adjusting the output power of the fan to the target output power, the next step is to obtain the temperature value of the heating wire as the second target temperature value after a preset second time interval.

[0044] It should also be understood that the term “and / or” as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0045] Example 1

[0046] See Figure 1 Embodiment 1 of the present invention provides a method for rapid heating of a hot air gun. The hot air gun includes a heating wire and a fan. A controller is connected to the heating wire and the fan respectively. The method is applied to the controller. The method for rapid heating of a hot air gun in Embodiment 1 includes the following steps: S101-S105.

[0047] S101, the temperature value of the heating wire is obtained as the first target temperature value.

[0048] In this embodiment of the invention, by obtaining the temperature value of the heating wire of the hot air gun as the first target temperature value, it is possible to determine whether the current temperature value of the heating wire of the hot air gun has reached the preset set temperature. Furthermore, based on the determination result, it can be determined whether the output power of the fan needs to be adjusted. A high output power of the hot air gun fan will accelerate heat loss, resulting in a slow temperature rise of the heating wire during the heating process. Therefore, adjusting the fan's output power can enable the heating wire of the hot air gun to achieve rapid heating.

[0049] S102, the first target temperature value is divided by the preset set temperature to obtain the first temperature ratio.

[0050] In this embodiment of the invention, the preset temperature can be set according to actual needs. Taking a preset temperature of 500°C as an example, if the currently detected temperature of the heating wire is 100°C, then the first temperature ratio is the temperature of the heating wire divided by the preset temperature, that is, 100°C divided by 500°C, so the first temperature ratio is 0.2.

[0051] S103, calculate the product of the first temperature ratio and the preset maximum power value as the output power of the fan, and control the fan to output at the output power.

[0052] In this embodiment of the invention, the preset maximum power value is specifically 60. For example, if the set temperature is 500°C, and the currently detected temperature of the heating wire is 100°C, the product of the first temperature ratio and the preset maximum power value is calculated as the output power of the fan, which is 0.2 × 60 = 12. 12 is the percentage of the fan's maximum output power. For example, if the fan's maximum output power is 30 watts, then the fan's output power should be controlled at 12% × 30W = 3.6W.

[0053] In one embodiment, step S103 above includes steps S1031-S1032.

[0054] S1031, obtain the product of the first temperature ratio and the preset maximum duty cycle as the target duty cycle of the fan.

[0055] Specifically, taking the above-mentioned set temperature of 500℃ as an example, the currently detected temperature of the heating wire is 100℃, the first temperature ratio is 0.2, the preset maximum duty cycle is 60%, then the target duty cycle is 12%.

[0056] S1032, a PWM drive signal is generated based on the target duty cycle, and the PWM drive signal is sent to the fan.

[0057] Specifically, a PWM drive signal is generated based on the target duty cycle, and the PWM drive signal is sent to the fan. The fan output can be adjusted according to the calculated target duty cycle. For example, if the maximum power of the fan is limited to 20W, then the target duty cycle multiplied by the maximum power of the fan (20W) is 12% × 20W = 2.4W. In this case, the fan needs to be controlled to output power of 2.4W.

[0058] S104, after a preset first time interval, determine whether the temperature value of the heating wire has reached the set temperature.

[0059] In this embodiment of the invention, the preset first time interval can be set according to actual needs.

[0060] S105, if the temperature value of the heating wire does not reach the set temperature, proceed to the step of obtaining the temperature value of the heating wire as the first target temperature value.

[0061] Specifically, if the temperature of the heating wire does not reach the set temperature, the process will proceed to the step of obtaining the temperature of the heating wire as the first target temperature value. That is, after a first time interval, if the current temperature has risen from 100°C to 125°C, and 125°C still does not meet the set temperature of 500°C, then 125°C is divided by 500°C to obtain the temperature ratio, and the output power of the fan is adjusted to enable the hot air gun to heat up quickly.

[0062] Example 2

[0063] Embodiment 2 of the present invention provides a method for rapid heating of a hot air gun. The hot air gun includes a heating wire and a fan. A controller is connected to the heating wire and the fan respectively. The method is applied to the controller. The method for rapid heating of a hot air gun in Embodiment 2 includes the following steps: S206-S210.

[0064] S201, the temperature value of the heating wire is obtained as the first target temperature value.

[0065] In this embodiment of the invention, by obtaining the temperature value of the heating wire of the hot air gun as the first target temperature value, it is possible to determine whether the current temperature value of the heating wire of the hot air gun has reached the preset set temperature. Furthermore, based on the determination result, it can be determined whether the output power of the fan needs to be adjusted. A high output power of the hot air gun fan will accelerate heat loss, resulting in a slow temperature rise of the heating wire during the heating process. Therefore, adjusting the fan's output power can enable the heating wire of the hot air gun to achieve rapid heating.

[0066] S202, the first target temperature value is divided by the preset set temperature to obtain the first temperature ratio.

[0067] In this embodiment of the invention, the preset temperature can be set according to actual needs. Taking a preset temperature of 500°C as an example, if the currently detected temperature of the heating wire is 100°C, then the first temperature ratio is the temperature of the heating wire divided by the preset temperature, that is, 100°C divided by 500°C, so the first temperature ratio is 0.2.

[0068] S103, calculate the product of the first temperature ratio and the preset maximum power value as the output power of the fan, and control the fan to output at the output power.

[0069] In this embodiment of the invention, the preset maximum power value is specifically 60. For example, if the set temperature is 500°C, and the currently detected temperature of the heating wire is 100°C, the product of the first temperature ratio and the preset maximum power value is calculated as the output power of the fan, which is 0.2 × 60 = 12. 12 is the percentage of the fan's maximum output power. For example, if the fan's maximum output power is 30 watts, then the fan's output power should be controlled at 12% × 30W = 3.6W.

[0070] In one embodiment, step S203 above includes steps S2031-S2032.

[0071] S2031, obtain the product of the first temperature ratio and the preset maximum duty cycle as the target duty cycle of the fan.

[0072] Specifically, taking the above-mentioned set temperature of 500℃ as an example, the currently detected temperature of the heating wire is 100℃, the first temperature ratio is 0.2, the preset maximum duty cycle is 60%, then the target duty cycle is 12%.

[0073] S2032, a PWM drive signal is generated based on the target duty cycle, and the PWM drive signal is sent to the fan.

[0074] Specifically, a PWM drive signal is generated based on the target duty cycle, and the PWM drive signal is sent to the fan. The fan output can be adjusted according to the calculated target duty cycle. For example, if the maximum power of the fan is limited to 20W, then the target duty cycle multiplied by the maximum power of the fan (20W) is 12% × 20W = 2.4W. In this case, the fan needs to be controlled to output power of 2.4W.

[0075] S204, after a preset first time interval, determine whether the temperature value of the heating wire has reached the set temperature.

[0076] In this embodiment of the invention, the preset first time interval can be set according to actual needs.

[0077] S205, if the temperature value of the heating wire does not reach the set temperature, proceed to the step of obtaining the temperature value of the heating wire as the first target temperature value.

[0078] Specifically, if the temperature of the heating wire does not reach the set temperature, the process will proceed to the step of obtaining the temperature of the heating wire as the first target temperature value. That is, after a first time interval, if the current temperature has risen from 100°C to 125°C, and 125°C still does not meet the set temperature of 500°C, then 125°C is divided by 500°C to obtain the temperature ratio, and the output power of the fan is adjusted to enable the hot air gun to heat up quickly.

[0079] S206, if the temperature of the heating wire reaches the set temperature, control the fan to output power.

[0080] Specifically, taking a set temperature of 500℃ as an example, if the temperature of the heating wire reaches 500℃, it means that the heating of the hot air gun has been completed, and the output power of the fan will be output at a stable power.

[0081] S207, after a preset second time interval, the temperature value of the heating wire is obtained as the second target temperature value.

[0082] In this embodiment of the invention, the preset second time interval can be set according to actual needs, such as 2 seconds, 4 seconds, 6 seconds, etc., and is not limited here. By obtaining the temperature value of the heating wire as the second target temperature value, it can be determined whether the temperature of the heating wire remains at the set temperature after the hot air gun completes rapid heating. Then, based on the determination result, it can be decided whether it is necessary to control the output of the fan to keep the temperature of the heating wire at the set temperature.

[0083] S208, determine whether the second target temperature value is less than the set temperature.

[0084] Specifically, taking the aforementioned set temperature of 500℃ as an example, it can be determined whether the temperature of the heating element remains at the set temperature after the hot air gun completes rapid heating. Based on the determination result, it can be decided whether to control the fan output to maintain the heating element temperature at the set temperature. Controlling the fan output using the second target temperature value can ensure that the heating element temperature remains at the set temperature even when the hot air gun's battery power is low.

[0085] S209, if the second target temperature value is less than the set temperature, reduce the output power of the fan.

[0086] Specifically, if the detected second target temperature is lower than the set temperature, such as after the hot air gun has rapidly heated up, and the battery power is insufficient, causing the heating wire temperature to drop to 490°C, which is below the set temperature of 500°C, the fan output power can be reduced to decrease heat loss and allow the heating wire temperature to rise back to the set temperature of 500°C.

[0087] In one embodiment, step S209 above includes steps S2091-S2093.

[0088] S2091, calculate the temperature difference between the temperature value of the heating wire and the second target temperature value.

[0089] Specifically, by calculating the temperature difference between the heating wire's temperature and the second target temperature, the extent to which the fan's output power is reduced can be controlled based on this temperature difference. The fan output can be divided into four levels: Level 1, Level 2, Level 3, and Level 4. Level 4 represents the output airflow level when the heating wire's temperature is at the set temperature of 500℃.

[0090] S2092, determine the target output power corresponding to the temperature difference from the preset temperature difference-power correspondence table.

[0091] In this embodiment of the invention, the preset temperature difference-power correspondence table can be set according to actual needs. The four fan output levels—Level 1, Level 2, Level 3, and Level 4—correspond to the fan's output power, specifically 70%, 80%, 90%, and 100% of the fan's maximum output power, respectively. The temperature difference can then be divided into three intervals: 0-100, 101-300, and 301-500. 0-100 corresponds to a fan level reduction to Level 3, 101-300 to Level 2, and 301-500 to Level 1. It should be noted that both the temperature difference intervals and fan levels can be set according to actual needs. In other embodiments, different temperature difference intervals can correspond to different fan levels; this is not limited here.

[0092] S2093, adjust the output power of the fan to the target output power.

[0093] Specifically, as mentioned above, the target output power corresponding to the temperature difference is determined from the preset temperature difference-power correspondence table. The four fan output levels (Level 1, Level 2, Level 3, and Level 4) correspond to the fan's output power, respectively 70%, 80%, 90%, and 100% of the fan's maximum output power. Therefore, the target output power can be derived from the fan's output level. During the operation of the hot air gun, the airflow is output at Fcur = 500 L / Min. If the actual temperature does not reach the set temperature, the airflow begins to decrease. The airflow Fcur decreases by one level to Fcur = 400 L / Min, at which point the actual temperature will rise again. After working for a period of time, if the actual temperature still does not reach the set temperature, the airflow Fcur decreases by another level to Fcur = 300 L / Min. 500 L / Min, 400 L / Min, 300 L / Min, and 200 L / Min correspond to the aforementioned Level 4, Level 3, Level 2, and Level 1, respectively.

[0094] After step S2093, proceed to step S207, which is the step of obtaining the temperature value of the heating wire as the second target temperature value after a preset second time interval.

[0095] Specifically, by cyclically judging whether the second target temperature value is lower than the set temperature, the output air volume of the fan is continuously adjusted, thereby extending the purpose of setting the heat preservation until the temperature value of the heating wire is adjusted to the original set temperature.

[0096] S210, if the second target temperature value is not lower than the set temperature, control the fan to maintain the output power.

[0097] Specifically, if the second target temperature is not lower than the set temperature, the fan is controlled to maintain output at the set power. For example, if the set temperature is 500°C, and the second target temperature is 500°C, then the fan is controlled to output at the current power to keep the temperature of the heating element at the set temperature, and the hot air gun continues to work stably.

[0102] The calculation unit 403 is used to calculate the product of the first temperature ratio and the preset maximum power value as the output power of the fan, and control the fan to output at the output power.

[0103] The first judgment unit 404 is used to determine whether the temperature value of the heating wire has reached the set temperature after a preset first time interval.

[0104] The conversion unit 405 is used to switch to the step of obtaining the temperature value of the heating wire as the first target temperature value if the temperature value of the heating wire does not reach the set temperature.

[0107] A PWM drive signal is generated based on the target duty cycle, and the PWM drive signal is sent to the fan.

[0111] The second acquisition unit 407 is used to acquire the temperature value of the heating wire as the second target temperature value after a preset second time interval.

[0112] The second judgment unit 408 is used to determine whether the second target temperature value is less than the set temperature.

[0113] If the second target temperature value is less than the set temperature, the reducing unit 409 reduces the output power of the fan.
