The air outlet position of the blower 13 is: the position where the nozzle of the blower 13 is connected; or, the air outlet position of the blower 13 when no tuyere is installed.
The blower 13 refers to a blower to be parameter-calibrated. Alternatively, the blower 13 may be provided without a tuyere assembly, a handle housing, or the like; alternatively, the blower 13 may be a complete blower 13.
Optionally, the specific positional relationship refers to a distance between the first temperature measuring component 12 and the air outlet position being a first preset value d. The first preset value is determined according to the length of the nozzle of the blower 13. Such as: the first preset value is equal to the length of the tuyere, and at the moment, if the length of the tuyere is 10cm, the first preset value is 10cm; or, the first preset value is greater than the length of the tuyere and less than the sum of the length of the tuyere and the preset constant, at this time, if the length of the tuyere is 10cm and the preset constant is 3cm, the first preset value may be 11cm or 12cm, and the setting mode of the first preset value is not limited in this embodiment.
In one example, the first temperature measurement assembly 12 includes a wind deflector 121, where the wind deflector 121 is located in the direction of the air outlet, and the distance between the wind deflector 121 and the air outlet is a first preset value, and a temperature measurement element 122 is disposed in the wind deflector 121 or on the surface of the wind deflector 121 facing the air outlet.

The NTC temperature control module is used to control the heating temperature of the air flow by the blower 13, and may be a thermistor. The NTC voltage value is positively correlated with the heating temperature, which is positively correlated with the outlet air temperature of the blower 13. Based on this, when the outlet air temperature of the blower 13 reaches a desired temperature, the calibration unit 14 takes the NTC voltage value corresponding to the outlet air temperature as a calibration value of the NTC temperature control module.
The calibration unit 14 may write the determined calibration value into the blower 13, such as: written in the control unit 131 of the blower 13. The control unit 131 may be a printed circuit board (Printed Circuit Board, PCB) of the blower 13. At this time, the blower parameter calibration apparatus further includes a probe positioning jig 15, the probe positioning jig 15 is fixed with a probe 16, the probe 16 is used for connecting a communication interface of the calibration unit 14 and a control unit 131 of the blower 13 to realize communication between the calibration unit 14 and the control unit 131 of the blower 13, and the calibration unit 14 is used for acquiring a temperature control parameter of the blower 13 and an operation parameter of a heating element of the blower 13 from the control unit 131 of the blower 13. The calibration unit 14 is further configured to store a calibration value of the temperature control parameter to the control unit 131.
When the parameter calibration is performed, the probe 16 is electrically connected to the control unit 131 in the blower 13 through a test point 132 on the control unit 131.
Optionally, in order to ensure that the probe 16 is docked with the test point 132, a positioning hole 133 is further provided on the control unit 131, and the probe 16 is docked with the test point 132 by inserting into the positioning hole 133.
When the temperature calibration is performed, the calibration unit 14 is respectively in communication connection with the first temperature measuring component 12 and the control component 131 in the blower 13, and the calibration unit 14 controls the NTC temperature control module to work by controlling the control component 131 in the blower 130.
The process of temperature calibration by the calibration unit 14 includes: controlling the blower 13 to operate; during operation, the air outlet temperature of the blower 13 is detected in real time; in the case where the outlet air temperature is the target temperature, the measured value of the temperature control parameter of the blower 13 is determined as the calibrated value of the temperature control parameter.
Alternatively, the target temperature is stored in the calibration unit 14 in advance, and the target temperature is uniformly calibrated for the blowers 13 of the same model.
Alternatively, when the blower 13 includes at least two gear steps, the target temperatures corresponding to the different gear steps are different.
