[0061] The power acquisition component 120 is used to acquire the power parameters of the hair dryer 130. Among them, the power parameters include the overall power of the hair dryer 130, in other words, the sum of the powers of each component in the hair dryer 130 when working.

[0063] Optionally, the power collection component 120 can be part of the calibration terminal 110; or, the power collection component 120 is a device independent of the calibration terminal 110.

[0064] The hair dryer 130 includes a control component 131 and a heating element 132. The control component 131 is communicatively connected to the heating element 132.

[0065] The control component 131 is used to control the hair dryer 130, such as: controlling the start and stop of the hair dryer 130, the heating temperature of the heating element 132, the on and off of the heating element 132, etc. In one example, the control component 131 is a printed circuit board (PCB) of the hair dryer 130.

[0066] The heating element 132 is used to heat the gas flowing through the hair dryer 130. Optionally, the heating element 132 can be a heating wire, and the number of heating wires can be one or more. The present embodiment does not limit the implementation manner of the heating element 132.

[0067] The calibration terminal 110 is used to calibrate the power of the hair dryer 130. Optionally, the calibration terminal 110 can be a computer, a mobile phone, a tablet computer, or a laptop computer, etc. The present embodiment does not limit the device type of the calibration terminal 110.

[0068] When performing power calibration, the calibration terminal 110 is communicatively connected to the power collection component 120 and the control component 131 respectively, and by controlling the control component 131 in the hair dryer 130, the heating element 132 is controlled to work.

[0069] The process of the calibration terminal 110 performing power calibration includes: obtaining the power collected by the power collection component 120 when the hair dryer 130 is working and the working parameters of the heating element 132; establishing a first correspondence between the power and the working parameters. After that, the calibration terminal 110 stores the first correspondence in the hair dryer 130.

[0070] Among them, the working parameters include the time characteristic parameters of the conduction of the heating element 131 of the hair dryer 130 within a predetermined period. In other words, the working parameters are used to indicate when the heating element 131 is turned on and when it is turned off within a predetermined period.

[0071] In one example, the time characteristic parameter is the number of half - waves during which the heating element 131 is turned on. Among them, the predetermined period includes a plurality of half - waves. A half - wave refers to half of the waveform in the sinusoidal voltage signal that powers the heating element 131, and the voltage at the starting position of this half - wave is 0V, and the voltage at the ending position is 0V.

[0072] Among them, the power when the hair dryer 130 is operating includes a target power range. In this way, the first correspondence includes the correspondence between the target power range and the target range of the operating parameters.

[0073] The target power range is pre - stored in the calibration terminal 110. Optionally, when the hair dryer 130 includes at least two gears, the target power ranges corresponding to different gears are different.

[0075] Optionally, the target power range is determined based on the rated power corresponding to each gear. For example: if the rated power is 100W, the corresponding target power range can be [90W, 110W].

Optionally, the temperature acquisition component 140 can be a temperature - measuring element such as a thermocouple or a thermistor. The implementation manner of the temperature acquisition component 140 is not limited in this example.

[0081] Optionally, in the present application, the hair dryer 130 is used to: determine a target range of operating parameters of the heating element of the hair dryer according to the target power range of the hair dryer 130, where the operating parameters include a time characteristic parameter of the conduction of the heating element of the hair dryer within a predetermined period; control the operating parameters of the heating element to remain within the target range so that the power of the hair dryer remains within the target power range.

[0082] In one example, determining the target range of the operating parameters of the heating element of the hair dryer according to the target power range of the hair dryer includes: obtaining a first correspondence between the operating parameters and the power of the hair dryer established in advance; calculating the target range of the operating parameters according to the target power range and the first correspondence.

[0083] In yet another example, determining the target range of the operating parameters of the heating element corresponding to the target power range includes: obtaining a first correspondence between the operating parameters and the power of the hair dryer established in advance; obtaining a second correspondence between the operating parameters and the outlet air temperature of the hair dryer established in advance; calculating the target range of the operating parameters of the heating element according to the target power range of the hair dryer, the target temperature range of the outlet air temperature, the first correspondence, and the second correspondence.

[0084] In this embodiment, by pre-determining the operating parameters of the heating element when the hair dryer operates within the target power range, operating according to these operating parameters can ensure that the power of the hair dryer remains within the target power range. In this way, it is possible to make the power ranges of different hair dryers of the same model operating in the same gear consistent without adjusting the differences between the hair dryers of the same model. Therefore, different hair dryers of the same model can all operate at the desired power.

[0096] To summarize, the hair dryer power control method provided in the present embodiment determines the target range of the working parameters of the heating element of the hair dryer according to the target power range of the hair dryer, the working parameters including the time characteristic parameters of the heating element of the hair dryer being turned on within a predetermined period; controls the working parameters of the heating element to remain within the target range, so that the power of the hair dryer remains within the target power range; can solve the problem that due to the differences between different hair dryers, different hair dryers working at the same gear have different actual working powers; by predetermining the working parameters of the heating element when the hair dryer works within the target power range, working according to the working parameters can ensure that the power of the hair dryer remains within the target power range, thus, the power ranges of different hair dryers working at the same gear can be made consistent without adjusting the differences between hair dryers of the same model, and therefore, different hair dryers of the same model can all work at the desired power.
