If the air inlet channel 201 in the embodiment of the present application is disposed on the blowing portion 10, the air inlet channel 201 may refer to a portion of the main blowing channel near the air inlet end 104, and the environment detection unit 202 in the air inlet channel 201 may be disposed near the air inlet end 104 to detect an environment state of the blowing environment.

In this embodiment, the fan 302 may adopt a high-speed brushless non-inductive motor, and the sampling speed of the fan 302 is controlled in a closed loop manner to achieve accurate control of the air output.

It can be understood that, in order to accelerate the evaporation of water on the object to be blown, the working device of the blowing apparatus may further include a heating wire 301, the heating wire 301 may be disposed in the main blowing channel, the heating wire 301 may heat the air flow in the main blowing channel, and the heated air flow flows out from the air outlet end 103 and acts on the object to be blown, so that the water on the object to be blown may be evaporated quickly.

In this embodiment, 1200W can be set for to the maximum power of heater 301, still can be equipped with high temperature fusing protection subassembly for heater 301 to realize the high temperature protection, heater 301 can be connected with the silicon controlled rectifier, and the output power that the silicon controlled rectifier can be according to the Pulse Width Modulation (PWM) signal regulation heater 301 that the treater output is heating power.

Because be provided with fan 302 and heater 301 in the main entrance of blowing, if inlet air channel 201 sets up on the portion 10 of blowing, for the main entrance of blowing is close to the part of air inlet end 104, then the equipment during operation or work back short time of blowing works once more, because fan 302, heater 301 are located same passageway with environment detecting element 201, fan 302 and heater 301 influence the accurate nature of the environmental state that environment detecting element 202 detected easily, make the environmental state information that detects and actual environmental state information have great error. Therefore, in some embodiments of the present application, the air intake channel 201 may be disposed on the handle portion 20.

At this time, the air inlet of the air inlet channel 201 may be disposed along the outer surface of the handheld portion 20, the air inlet channel 201 may be extended into the handheld portion 20 from the air inlet, and the environment detection unit 202 may be disposed near the air inlet of the air inlet channel 201, so that the environment detection unit 202 may contact with the external environment to detect the environment state of the blowing environment.

It can be understood that the environment state information of the blowing environment may be information of ambient humidity, ambient temperature, and the like, and the environment detection unit 202 may be any one of the existing temperature sensor and humidity sensor or a temperature and humidity sensor integrated with the temperature sensor and humidity sensor, and is not limited herein.

The air inlet of the return air channel 101 can be arranged at the front end of the blowing part 10, the return air channel 101 can be extended to the air inlet of the fan 302 from the air inlet, when the fan 302 operates, the air inlet is influenced by negative pressure, the front end of the blowing part 10 is in contact with the air flow of the blowing object, namely, the return air of the blowing object, the air inlet of the return air channel 101 can be sucked into the air inlet of the fan 302, the return air detection unit 102 is arranged in the return air channel 101, and the air flow in contact with the blowing object, namely, the return air state of the return air of the blowing object can be detected.

It can be understood that the return air channel 101 may be disposed on at least one side of the main blowing channel, and the air inlet direction of the return air channel 101 is opposite to the air outlet direction of the main blowing channel, so that the air current that has contacted with the object to be blown may enter the return air channel 101, and the return air detection unit 102 disposed in the return air channel 101 may detect the return air state of the object to be blown.

It is understood that the return air state information of the blowing object may be information such as return air humidity, return air temperature, etc., and the return air detecting unit 102 may be any one of the existing temperature sensor and humidity sensor or a temperature and humidity sensor integrated with the temperature sensor and humidity sensor, and is not limited herein.

As shown in fig. 1, in some embodiments, the blowing apparatus may further include a distance detection unit 105, the distance detection unit 105 may be disposed at the wind outlet end 103 of the blowing part 10 for detecting a distance between the wind outlet end 103 and a surface of a blowing object, and the distance detection unit 105 may include any one or more existing distance sensors, such as a laser ranging sensor, an infrared ranging sensor, a radar ranging sensor, or a detection device integrated with a distance sensor, which is not limited herein.

Because the tuyere of different functions such as molding tuyere, hair care tuyere etc. can be installed on air-out end 103 at the equipment during operation of blowing, reach different air-out effects, and the tuyere probably can shelter from apart from detecting element 105 after the installation, and the distance detecting element 105 who is sheltered from will not normally work.

Therefore, in some embodiments, in order to prevent the air nozzle from blocking the distance detection unit 105, the distance detection unit 105 of the blowing device may be set to be at least two, each distance detection unit 105 may be independently electrically connected to the processor, and a connection line between every two distance detection units 105 does not pass through the central point of the air outlet end 103.

Each distance detecting unit 105 can independently detect, that is, as long as one distance detecting unit 105 detects the object to be blown, the processor can determine the distance between the air outlet end 103 and the object to be blown according to the distance value detected by the distance detecting unit 105.

Further, the distance detection units 105 may include an emitting area and a receiving area, and a connection line between the emitting area of each distance detection unit 105 and the emitting area of another distance detection unit 105 does not pass through the central point of the air outlet end; the line connecting the receiving area of each distance detecting unit 105 and the receiving area of another distance detecting unit 105 does not pass through the center point of the air outlet end 103. So, no matter what angle the tuyere is rotated to, the tuyere can not shelter from two apart from detecting element 105's launch site and receiving area simultaneously, has a distance detecting element 105 to be sheltered from all the time promptly, has at least one apart from detecting element 105 can normally work to ensure that blowing equipment can normal use.

In the above embodiment, when there are at least two distance detection units 105 that normally detect, the processor may receive at least two distance detection values or distance signals, and since a user may shake the blowing device back and forth when using the blowing device, different blowing angles may occur to the blowing device, which may cause inconsistency of the distance detection values detected by the distance detection units 105. If the processor controls the working states of the fan 302 and the heating wire 301 according to each distance detection value, the air outlet speed and the air temperature of the blowing device may be disordered, and the user experience is not good.

In order to avoid the above situation, in some embodiments of the present application, a correction circuit may be disposed on the processor, the correction circuit may be electrically connected to the distance detection unit 105, and the correction circuit may be configured to correct at least two distance detection values into one distance detection value, so that the processor may determine the operating states of the fan 302 and the heating wire 301 according to the corrected distance detection values. The manner of correcting the distance detection value by the correction circuit includes, but is not limited to, the following manners:

in one implementation, the correction circuit may randomly select one of the received at least two distance detection values to upload to the processor.

In another implementation, the correction circuit may select a smaller one of the received at least two distance detection values to upload to the processor.

In yet another implementation, the correction circuit may further calculate an average of the received at least two distance detection values, and upload the average to the processor.

It should be noted that the correction circuit may be provided as a separate component or may be integrated into the processor.

Referring to fig. 1 again, in the embodiment of the present application, the blowing device may further include a speaker 40 and a display screen 50, where the speaker 40 may be disposed on the handheld portion 20 and configured to broadcast the current working state, fault, prompt, and the like of the blowing device in a voice manner; display screen 50 can set up in the rear of portion of blowing 10 like air inlet end 104 department, and display screen 50 can the synchronous display blow equipment's information such as mode, relevant working parameter, and when switching blow equipment's operating range, display screen 50 can show the mode that is in at present, and loudspeaker 40 carries out voice broadcast in step.

In this embodiment, the processor may be a main control chip of the blowing device itself, or may be an independent control chip, and the processor may be equipped with a General-purpose input/output (GPIO) port, a Serial-Integrated Circuit (IIC) Interface, a Universal Asynchronous Receiver/Transmitter (UART), a Serial Peripheral Interface (SPI), an Analog-to-Digital Converter (ADC), a Liquid Crystal Display (LCD), and other common peripherals, and is respectively connected to the return air detection unit 102, the environment detection unit 202, the fan 302, the heater 301, the distance detection unit 105, the Display screen 50, and the speaker 40 in the above embodiments through the communication Interface or the bus, and adjusts working parameters of the fan 302 and the heater 301 according to detection results fed back by the detection units, and controls working parameters of the fan 302 and the heater 302 to achieve different operating states of the blowing device, thereby achieving different operating states of the blowing device.

Because the working parameters or the working mode of the existing air blowing equipment usually depend on the setting of a mechanical switch on the surface of a machine body or a control piece on a user interface by a user, if the user only depends on the preference of the user to pursue quick hair drying, the air blowing object can be damaged, and the comfort of the user can be reduced.

Based on this, the control method of the blowing apparatus of the present application includes:

acquiring environment state information of the blowing environment detected by an environment detection unit; determining a reference working parameter of the blowing equipment according to the environment state information, and controlling the blowing equipment to perform blowing operation based on the reference working parameter; the method comprises the steps of acquiring return air state information of return air of a detected air blowing object when a return air detection unit performs air blowing operation on air blowing equipment based on reference working parameters; and adjusting the reference working parameters according to the air return state information, and controlling the blowing equipment to perform blowing operation based on the adjusted working parameters.

Referring to fig. 2, fig. 2 is a schematic flow chart of a control method of a blowing apparatus provided in an embodiment of the present application. It should be noted that while a logical order is shown in the flow diagram, in some cases, the steps shown or described may be performed in an order different than presented herein. The control method of the blowing apparatus may include the following steps.

Step S201, acquiring environmental state information of the blowing environment detected by the environment detection unit.

As the somatosensory comfortable temperatures of users are different in different environments, for example, the somatosensory comfortable temperature range of a human body is 19-24 ℃ in summer and 17-22 ℃ in winter, for the blowing experience, the somatosensory comfortable temperature of the human body is about 55 ℃ in a hot air high-speed gear, and the somatosensory comfortable temperature of the human body is about 30 ℃ in a cold air high-speed gear.

It can be understood that along with the change of environmental state, the human body is different to the body sense comfort level that blows and send experience, if no matter under what kind of environmental state, all rely on user-set's gear control to blow equipment and blow the operation, then probably there is the not good condition of comfort level.

Therefore, in the embodiment of the application, the environmental state information detected by the environment detection unit contacting with the ambient air of the hair blowing environment can be acquired, so that the current state of the hair blowing environment is determined.

According to the above embodiments, it can be known from the description of the air blowing device that the environment detection unit can be disposed near the air inlet of the air inlet channel, so that the environment detection unit can contact with the external environment to detect the environment state of the air blowing environment, such as the environment temperature, the environment humidity, and the like.

It can be understood that the environment detection unit may sample the environment state information of the blowing environment according to a preset sampling period, for example, if the sampling frequency of the environment detection unit is set to 10Hz, the environment detection unit may sample 10 groups of environment state information of the blowing environment every second.

In this embodiment of the application, the manner in which the processor acquires the environmental status information detected by the environmental detection unit may be active acquisition, for example, an acquisition period may be configured in advance for the processor, and the processor periodically communicates with the environmental detection unit based on the acquisition period, so as to acquire the environmental status information detected by the environmental detection unit.

It can be understood that the processor may also obtain the environmental state information detected by the environment detection unit passively, for example, a sending period may be configured for the environment detection unit in advance, and after the environment detection unit samples the environmental state information of the hair blowing environment according to the preset sampling period, the environment detection unit may periodically communicate with the processor according to the sending period, so as to send the environmental state information to the processor, so that the processor obtains the environmental state information.

And S202, determining a reference working parameter of the blowing equipment according to the environment state information, and controlling the blowing equipment to perform blowing operation based on the reference working parameter.

After the environmental state information is obtained in step S201, the reference working parameter of the blowing device may be determined according to the environmental state information, and it can be understood that the reference working parameter may be a working parameter corresponding to a working device of the blowing device, for example, for a fan, the reference working parameter is a fan rotation speed, and for a heater, the reference working parameter is a heater power.

In order to avoid the situation that the detection deviation occurs due to external interference in the environment detection unit, in some embodiments, the environment state information may also be information subjected to denoising processing or optimization processing, for example, after the processor acquires the environment state information at the current time, the environment state information at the current time and an average value of all the environment state information in a period of time before the current time may be taken as the current environment state information, so as to improve data accuracy.

It can be understood that the reference working parameters of the blowing equipment are different for different environment states, so that the user can feel good in physical examination sense when the blowing equipment works based on the corresponding reference working parameters.

And step S203, air return state information of the air return of the air blowing object detected by the air return detection unit when the air blowing equipment performs air blowing operation based on the reference working parameters is obtained.

According to the above embodiment, it can be known from the description of the blowing device that when the blowing device performs the blowing operation, when the blower operates, the blower is affected by negative pressure, the air current that the front end of the blowing part contacts with the blowing object is the air return of the blowing object, the air current that the front end of the blowing part contacts with the blowing object can be sucked into the air inlet of the blower through the air inlet of the air return channel, and the air return detection unit is arranged in the air return channel and can detect the air current that the front end of the blowing part contacts with the blowing object is the air return state of the air return of the blowing object.

In the embodiment of the application, the return air detection unit can also sample the return air state information of the return air of the blowing object in the return air channel according to a preset sampling period, for example, the sampling frequency of the return air detection unit is set to 20Hz, and the return air detection unit can sample 20 groups of return air state information every second.

It can be understood that the manner of acquiring the return air state information detected by the return air detecting unit by the processor may be the same as the manner of acquiring the environmental state information detected by the environmental detecting unit, and please refer to the description of acquiring the environmental state information detected by the environmental detecting unit in step S201, which is not described herein again.

And S204, adjusting the reference working parameters according to the air return state information, and controlling the blowing equipment to perform blowing operation based on the adjusted working parameters.

Because in the process of blowing to the object of blowing, the state of the object of blowing is along with the length of time change of blowing, for example, along with the increase of length of time of blowing, the moisture on the object surface of blowing evaporates gradually, and the object of blowing changes into dry state by wet state gradually, and at this in-process, if the operating parameter of equipment of blowing remains invariable throughout, then not only can cause the waste of electric energy, still harms the object of blowing easily, and user's comfort is not good.

Therefore, in the process of carrying out the air blowing operation on the air blowing object by the air blowing equipment, the reference working parameters of the air blowing equipment can be adjusted according to the acquired air return state information.

It can be understood that the humiture value of the air current after with the object of blowing contact can reflect the current state of the object of blowing, according to the current state regulation benchmark operating parameter of the object of blowing, can make the operating condition of the equipment of blowing and the state phase-match of the object of blowing, therefore, return air state information can include return air humidity detected value and return air temperature detected value, the equipment of controlling blowing is based on the operating parameter operation of blowing after adjusting, not only can guarantee drying efficiency, can also improve user comfort, the protection object of blowing does not receive the damage.

In the embodiment of the application, the environmental status of the environment of blowing is detected through the environmental detection unit in the air inlet channel of setting on the equipment of blowing, and the benchmark operating parameter of the equipment of blowing is confirmed according to the environmental status information that obtains of detecting, when the equipment of blowing is based on this benchmark operating parameter operation of blowing, through the return air detecting element that sets up in the return air channel detection object return air's return air state of blowing, benchmark operating parameter is adjusted based on the return air state information that obtains of detecting, make the equipment of blowing blow the operation based on the operating parameter after adjusting, can ensure after the humiture change of the environment of blowing, the operating parameter of dynamic adjustment equipment of blowing, under the prerequisite of not losing drying efficiency, improve the travelling comfort, avoid damaging the object of blowing, the reliability of the equipment of blowing has been improved.

Next, the steps shown in FIG. 2 and the detailed description of the possible embodiments that may be used in the actual application will be described in detail.

In some embodiments of the present application, adjusting the reference operating parameter according to the return air status information may further include:

determining target working parameters of the blowing equipment according to the air return state information and the current blowing time of the blowing equipment; and adjusting the reference working parameters based on the preset adjusting parameters until the adjusted working parameters are matched with the target working parameters.

Because the blowing object gradually changes from wet to dry along with the increase of the blowing duration, in the embodiment of the application, the target working parameters can be determined according to the return air state information and the current blowing duration of the blowing equipment, and the target working parameters are the target working parameters of the fan and the heating wire corresponding to the current state of the blowing object reflected by the return air state information.

Through past experience or multiple experiments, it can be determined that the target working parameters have a nonlinear change rule along with different blowing time lengths, for example, in the previous period of the blowing process, because the surface humidity of a blowing object is relatively high, the state change of the blowing object is not obvious, the change of the return air state information such as the return air humidity detection value is not too large, and correspondingly, the change range of the target working parameters at the stage is not large;

in the middle period of the blowing process, because part of the moisture on the surface of the blowing object is evaporated in the previous period of time and the surface temperature of the blowing object is also raised, the blowing operation is continuously performed on the blowing object at the moment, the moisture on the surface of the blowing object is quickly evaporated in the current stage along with the continuous increase of the blowing time, and the state change of the blowing object is obvious at the moment, so that the change of the return air humidity detection value is large, and correspondingly, the target working parameter change range in the current stage is also correspondingly large;

and in a period of time after the moisture on the surface of the blowing object is nearly completely evaporated, namely the blowing process, because the surface humidity of the blowing object is small, the state change of the blowing object in the period is not obvious, therefore, the change of the return air humidity detection value is not too large, and correspondingly, the change range of the target working parameters in the period is not large.

Based on this, taking the heater power adjustment as an example, the present embodiment can determine the target heater power P by the following control logic function:

where t denotes the current blowing time duration, P _base Indicating the reference heater power.

Referring to fig. 3, fig. 3 is a schematic diagram of an adjustment curve of the target heater power adjusted according to the blowing time and the detected value of the return air humidity under the condition that the distance between the blowing device and the blowing object is constant, wherein the horizontal axis is the blowing time (unit/s) and the vertical axis is the target heater power (unit/kW).

It is understood that the lower humidity limit may be any value determined by experience or experiments, and may be in the form of a percentage value, for example, the lower humidity limit may be 15%, 20%, 25%, 30%, and the like, and the selection of the lower humidity limit may be determined according to the actual application scenario, and is not limited herein.

When the current blowing time is less than 10s and the detected value of the return air humidity is less than the lower limit of the humidity, the target heating wire power P can be calculated by the formula (1), that is, the current blowing time and the reference heating wire power P are obtained _base And (3) substituting the formula (1) to obtain the corresponding target heating wire power P.

Since the distance between the blowing object and the blowing device also affects the blowing effect, on the basis of obtaining the corresponding target heating wire power P according to equation (1), the target heating wire power P can be corrected and compensated based on the distance between the blowing object and the blowing device.

For example, if it is detected that the distance between the blowing object and the blowing device is smaller than a preset distance threshold, 25W may be added on the basis of the target heater power P to obtain a new target heater power; if it is detected that the distance between the blowing object and the blowing apparatus is greater than or equal to the distance threshold, 50W may be added on the basis of the target heater power P to further increase the heater power to ensure the blowing effect.

It should be noted that the specific power value of the correction compensation in this embodiment may be determined according to the actual application scenario, and is not limited herein.

If the current blowing time length is less than 10s and the return air humidity detection value is greater than or equal to the lower humidity limit, or if the current blowing time length is between 10s and 4min, namely 240s, the target heating wire power P can be calculated through the formula (2), namely the current blowing time length and the reference heating wire power P _base And (3) substituting the formula (2) to obtain the corresponding target heating wire power P.

If the blowing time is longer than 4min, the target heating wire power P can be calculated by the formula (3), namely the current blowing time and the reference heating wire power P _base And (4) substituting the formula (3) to obtain the corresponding target heating wire power P.

In this embodiment of the application, the determination method of the target fan rotation speed may refer to the determination method of the target heater power, and is not repeated here.

In one specific implementation, after determining the target fan rotation speed and the target heating wire power corresponding to the current state of the blowing object reflected by the return air state information, the processor may directly adjust the current fan rotation speed to the target fan rotation speed and adjust the current heating wire power to the target heating wire power, so that the blowing device performs the blowing operation based on the target fan rotation speed and the target heating wire power.

However, the implementation method is suitable for application scenarios with small adjustment range of working parameters, for example, the current fan rotating speed is closer to the target fan rotating speed, and the current heating wire power is closer to the target heating wire power.

For the application scene with large adjustment range of working parameters, if the parameter adjustment of the fan and the heating wire is directly performed in place in one step, the blowing object may be damaged due to abrupt change, and the user may have obvious discomfort.

Therefore, in another specific implementation, the reference working parameter may be further adjusted according to a preset adjustment parameter until the adjusted working parameter is consistent with the target working parameter.

In the embodiment of the application, the adjustment parameters may include an adjustment step length and an adjustment frequency, and the reference working parameter is gradually adjusted to the target working parameter based on the preset adjustment frequency and the adjustment step length, so that a problem that a user feels obtrusive due to large-amplitude adjustment of the working parameter can be avoided.

For example, the blowing device may further include a zero-crossing detection unit and a silicon controlled device electrically connected to the zero-crossing detection unit, and the silicon controlled device may control an electrical connection state between the power supply and the blowing device according to a Pulse Width Modulation (PWM) signal output by the processor, so as to gradually adjust an output power of the heater, i.e., a heater power.

Specifically, the zero-crossing detection unit may be connected to a power supply of the blowing device, and configured to detect a zero-crossing point of the power supply to generate a zero-crossing point signal, and output the zero-crossing point signal to the processor, and the processor may determine the zero-crossing point of the power supply according to the received zero-crossing point signal, so as to output a PWM signal to the thyristor device, so as to control the on-off state of the thyristor device.

It can be understood that the zero-crossing detection unit may be any one of the existing zero-crossing detection circuits, please refer to fig. 4, fig. 4 is a schematic circuit diagram of the zero-crossing detection unit provided in the embodiment of the present application, the zero-crossing detection unit includes a photocoupler U1, a diode D1, and some peripheral resistors and capacitors, and the circuit connection structure of the zero-crossing detection unit is specifically:

the anode of the illuminator of the photoelectric coupler U1 is connected with the live wire L of the power supply through a first resistor R1 and a second resistor R2, the cathode of the illuminator of the photoelectric coupler U1 is connected with the anode of a diode D1, the cathode of the diode D1 is connected with the zero line N of the power supply, and a first capacitor C1 is connected between the anode and the cathode of the illuminator of the photoelectric coupler U1; one end of a light receiver of the photoelectric coupler U1 is connected with a +3.3V working power supply through a third resistor R3, a ZERO crossing point signal ZERO is output to the processor through a fourth resistor R4, and the other end of the light receiver of the photoelectric coupler U1 is connected with a ground electrode GND.

The working principle of the zero-crossing detection unit is as follows:

when the power supply works in the positive half cycle, a light emitter of the photoelectric coupler U1 is conducted to emit light, a light receiver of the photoelectric coupler is conducted, and the output ZERO crossing point signal ZERO is a low level signal; when the power supply works in the negative half cycle, the light emitter of the photoelectric coupler U1 is not conducted, the light receiver of the photoelectric coupler is not conducted, and the output ZERO crossing point signal ZERO is a high level signal.

Therefore, when the power supply enters a negative half cycle from a positive half cycle, the ZERO crossing point signal ZERO jumps from a low level to a high level to form a rising edge; when the power supply enters a positive half cycle from a negative half cycle, the ZERO-crossing point signal ZERO jumps from a high level to a low level to form a falling edge.

The processor can determine the ZERO crossing point of the power supply period according to the level change/edge of the received ZERO crossing point signal ZERO, thereby outputting a PWM signal with a corresponding duty ratio to control the switch of the silicon controlled device.

If a complete regulation period is set to be 24 power source periods, and 1 power source period corresponds to 1 sine wave, then 24 power source periods correspond to 24 sine waves or 48 half waves, taking a heating wire as an example, if the maximum power of the heating wire is 1200W, the 1200W is evenly distributed to each half wave, each half wave corresponds to 25W, and the number of the on-off half waves of the silicon controlled device is regulated through a PWM signal, so that the regulation of the power of the heating wire can be realized, and thus, the power of the heating wire is refined, and the reference heating wire power is gradually regulated to the target heating wire power based on the regulation step length of 25W, so that the regulation process is smoother and not abrupt, and the air blowing object can be protected.

It can be understood that, for the adjustment of the fan rotation speed, the adjustment mode of the heater power can be referred to as well, and the details are not described herein.

In some embodiments of the present application, the return air status information includes a return air humidity detection value, and the reference operating parameter is adjusted based on a preset adjustment parameter until the adjusted operating parameter matches the target operating parameter, and then the method may further include:

acquiring a current return air humidity detection value detected by a return air detection unit, and if the current return air humidity detection value is larger than a preset return air humidity threshold value, increasing a target working parameter based on a first preset step length; and if the current return air humidity detection value is not larger than the return air humidity threshold value, the target working parameter is reduced based on a second preset step length.

In the embodiment of the application, after the working parameters of the blowing equipment are adjusted to the target working parameters, the working parameters can be further adjusted according to the actual blowing scene.

The first preset step length and the second preset step length respectively can comprise an adjusting step length aiming at the rotating speed of the fan and an adjusting step length aiming at the power of the heating wire, the return air humidity threshold value can be preset and set numerical values in any form, such as 0.6, 60%, 0.7, 70% and the like, the first preset step length and the second preset step length can be the same or different, and the first preset step length and the second preset step length can be specifically determined according to actual application scenes.

For example, it is set that the current return air humidity detection value is acquired every 50ms, and if the current return air humidity detection value acquired for the first time is greater than the return air humidity threshold value of 0.7, it can be determined that the blowing object is currently wet, and the target working parameter can be increased, so that for the blower, 0.5 ten thousand revolutions can be set as one level, 0.5 ten thousand revolutions can be increased on the basis of the target blower rotation speed, for the heater, 25W can be set as one level, and 25W can be increased on the basis of the target heater power; if the current return air humidity detection value obtained when the second 50ms comes is still larger than the return air humidity threshold value of 0.7, the rotating speed of the fan and the power of the heating wire can be continuously increased on the basis of the last adjustment.

It should be noted that, if the current return air humidity detection value is continuously greater than the return air humidity threshold value 0.7, when the rotation speed of the fan and the power of the heating wire are adjusted, the rotation speed of the fan and the power of the heating wire need to be stopped being adjusted until the upper limit of the rotation speed of the fan and the upper limit of the power of the heating wire are reached.

If the obtained current return air humidity detection value is less than or equal to the return air humidity threshold value 0.7, the target fan rotating speed and the target heating wire power can be adjusted down in a stepped mode, for example, the rotating speed of the fan is set to decrease 2500 revolutions every 2s, and the heating wire power is set to decrease 25W every 3s until the rotating speed of the fan and the heating wire power are adjusted down to the reference value corresponding to the current distance between the blowing object and the blowing equipment.

In some embodiments of the present application, determining a reference operating parameter of the blowing device according to the environmental status information may further include:

acquiring a distance detection value between an air outlet end detected by a distance detection unit and the surface of an air blowing object; and determining a reference working parameter of the blowing equipment according to the distance detection value and the environmental state information.

It can be understood, if the air-out end of the equipment of blowing is nearer with the distance between the object surface of blowing, then the equipment of blowing just can reach good effect of blowing based on less benchmark working parameter work, and still continue to use less benchmark working parameter work when the air-out end of the equipment of blowing is far away with the distance on object surface of blowing, then not only can not reach the effect of blowing of ideal, still greatly reduced efficiency of blowing, consequently, the reference working parameter of the equipment of blowing can be confirmed according to the air-out end that distance detecting element detected and the distance detection value and the environmental condition information between the object surface of blowing.

The environmental state information includes an environmental humidity detection value and an environmental temperature detection value, and for the environmental humidity detection value, if the environmental humidity detection value is less than or equal to a preset humidity threshold value, for example, 80%, it can be determined that the current blowing environment humidity is low, and at this time, the reference working parameter of the blowing device can be determined according to the environmental temperature detection value and the distance detection value.

On the contrary, if the detected value of the environmental humidity is greater than the humidity threshold value by 80%, it can be determined that the humidity of the current blowing environment is high, and it may be that the blowing operation is performed in the high-humidity environment such as a bathroom, and at this time, the processor may prompt the user to set the operating mode of the blowing device to the quick-drying mode or directly control the blowing device to enter the quick-drying mode, so as to control the high-speed rotation of the blower and the operation of the heating wire with the maximum heating power, and to implement the blowing operation of drying the blowing object at the high wind speed and the high wind temperature.

It should be noted that, when equipment of blowing worked under the rapid-curing cutback mode, if detect the air-out end and blow the distance detection value between the object and last being less than or equal to predetermined safe distance threshold value in a predetermined short period, then the heater can be controlled to the treater and stop generating heat, close the heater promptly, control loudspeaker voice prompt user distance is too near simultaneously, scald easily, and when control loudspeaker voice prompt, the treater can also control the fan rotational speed simultaneously and reduce, so that the user can accurately discern the speech content.

For the ambient temperature detection value, in this embodiment of the present application, it may be first determined whether the ambient temperature detection value can represent the ambient temperature of the current blowing environment, and when it is determined that the ambient temperature detection value can represent the ambient temperature of the current blowing environment, the reference working parameter of the blowing device is determined based on the distance detection value and the ambient temperature detection value.

In some embodiments of the present application, the blowing apparatus may further include a temperature detection unit for detecting a temperature of the heater; the air return state information comprises an air return temperature detection value; determining a reference operating parameter of the blowing device according to the distance detection value and the ambient temperature detection value may further include:

acquiring a temperature value of the heating wire detected by a temperature detection unit; and if the difference between the temperature value and the environment temperature detection value is not greater than a preset temperature difference threshold value, or the difference between the temperature value and the return air temperature detection value is not greater than the temperature difference threshold value, determining the reference working parameters of the blowing equipment according to the distance detection value and the environment temperature detection value.

In this embodiment of the application, the temperature detection unit may be any one of the existing contact or non-contact temperature sensors, the temperature difference threshold may be set to any value such as 2, 3, 5, and the temperature difference threshold may be specifically determined according to an actual application scenario, and is not limited herein.

If the difference between the temperature value of the heating wire detected by the temperature detection unit and the ambient temperature detection value is smaller than or equal to the temperature difference threshold value, or the difference between the temperature value of the heating wire detected by the temperature detection unit and the return air temperature detection value is smaller than or equal to the temperature difference threshold value, the temperature of the handheld portion and the temperature of the heating wire can be determined to be consistent, or the temperature of the blowing portion and the temperature of the heating wire can be determined to be consistent, so that the blowing equipment can be further determined not to be used in a short time, namely the starting is in a cold state, at the moment, the ambient temperature detection value detected by the ambient detection unit of the handheld portion can reflect the current actual ambient temperature, and therefore the reference working parameters of the blowing equipment can be determined according to the distance detection value and the ambient temperature detection value.

On the contrary, if the difference between the temperature value of the heating wire detected by the temperature detection unit and the ambient temperature detection value is greater than the temperature difference threshold value, or the difference between the temperature value of the heating wire detected by the temperature detection unit and the return air temperature detection value is greater than the temperature difference threshold value, the temperature difference between the temperature of the handheld portion and the temperature of the heating wire can be determined to be larger, so that the temperature of the handheld portion and the temperature of the heating wire can be further determined to be larger, namely the starting of the blowing equipment is hot in a short time, at the moment, the ambient temperature detection value detected by the ambient detection unit of the handheld portion cannot reflect the current actual ambient temperature, under the circumstance, the processor can obtain the ambient temperature detection value corresponding to the last cold starting of the blowing equipment, and the reference working parameter of the blowing equipment can be determined according to the distance detection value and the ambient temperature detection value.

In another specific implementation, a temperature threshold value, for example, 50 ℃ may be determined according to past experience and multiple experiments, the temperature value of the heating wire detected by the temperature detection unit is directly compared with the temperature threshold value, if the temperature value is smaller than the temperature threshold value, it may be determined that the blowing device is not used in a short time, that is, the starting is a cold starting, and at this time, an ambient temperature detection value detected by the ambient detection unit at the handheld portion may reflect a current actual ambient temperature, so that a reference working parameter of the blowing device may be determined according to the distance detection value and the ambient temperature and humidity detection value.

If the temperature value is greater than or equal to the temperature threshold value, it can be determined that the blowing device is used in a short time, that is, the starting is a hot starting, at this time, an ambient temperature detection value detected by an ambient detection unit at the handheld portion cannot reflect the current actual ambient temperature, under this scenario, the processor can obtain an ambient temperature detection value corresponding to the last cold starting, and determine the reference working parameter of the blowing device according to the distance detection value and the ambient temperature detection value.

In the embodiment of the application, under different ambient temperatures and different distances, the benchmark working parameters of the blowing equipment can be different, specifically, the benchmark fan rotating speed and the benchmark heating wire power corresponding to different distances can be recorded in the form of the association table under different ambient temperatures.

For example, for the case that the ambient temperature is greater than or equal to 30 ℃, the reference fan rotating speed and the reference heating wire power corresponding to different distance values are recorded through the following association table I; aiming at the condition that the environmental temperature is not less than 25 ℃ and less than 30 ℃, recording the reference fan rotating speed and the reference heating wire power corresponding to different distance values through a second association table as follows; for the condition that the environmental temperature is not less than 20 ℃ and less than 25 ℃, recording the reference fan rotating speed and the reference heating wire power corresponding to different distance values through a third association table as follows; and recording the reference fan rotating speed and the reference heating wire power corresponding to different distance values through the following correlation table IV aiming at the condition that the environmental temperature is less than 20 ℃.

After the ambient temperature of the current blowing environment is determined according to the ambient temperature detection value, the processor can read the association table corresponding to the ambient temperature, so that the reference fan rotating speed and the reference heating wire power corresponding to the current distance detection value are searched in the association table, and the fan is controlled to work based on the reference fan rotating speed and the heating wire is controlled to work based on the reference heating wire power.

It can be understood that, because the user may make a round trip to rock the blowing equipment when using the blowing equipment, change the air-out end of blowing equipment and the distance between the object of blowing, consequently, if distance detecting element can be according to the detection frequency who sets for detect the distance between object of blowing and the air-out end periodically, if the distance detected value that detects changes, corresponding benchmark operating parameter also can carry out corresponding adjustment to make the temperature and the air output of the wind that use on the object of blowing invariable, improve user's comfort.

It can be understood that the blowing device may be configured with a plurality of operating modes, for example, a cold air mode, a quick drying mode, a hair care mode and an intelligent mode, when the blowing device operates in the cold air mode, the quick drying mode and the hair care mode, the blower speed and the heater power of the blowing device may be preset constant values corresponding to the respective modes, and in the intelligent mode, the blower speed and the heater power may be adjusted according to the control method of the blowing device in any embodiment of the present application, so in some embodiments of the present application, the environment state information of the environment blown and detected by the environment detecting unit may be further included:

acquiring an air blowing instruction; acquiring environment state information of a blowing environment detected by an environment detection unit in response to a blowing instruction; or extracting the working mode information carried in the blowing instruction; determining the working mode of the blowing equipment according to the working mode information; and when the working mode of the blowing equipment is a preset target mode, acquiring the environment state information of the blowing environment detected by the environment detection unit.

It can be understood that the blowing instruction may be a power-on instruction that a user sends to the processor through a mechanical key on the blowing device or an interactive control on the display screen, and after the processor receives the power-on instruction, the processor may directly communicate with the environment detection unit in response to the power-on instruction to obtain the environment state information detected by the environment monitoring unit.

The user can also select the working mode of the blowing operation of the blowing device through a mechanical key or an interactive control, so that the blowing instruction can also carry working mode information selected by the user, the processor can read the mode identification code in the blowing instruction after acquiring the blowing instruction carrying the working mode information such as the mode identification code, and determines the working mode corresponding to the mode identification code, when the extracted mode identification code is a preset target mode such as the identification code corresponding to the intelligent mode, the processor can communicate with the environment detection unit, and the environment state information detected by the environment detection unit is acquired.

If the extracted mode identification code is the identification code corresponding to the quick-drying mode, the processor can control the blowing equipment to blow air according to the rotating speed of the fan and the power of the heating wire in the preset quick-drying mode. For example, when the air blowing device works in the quick drying mode, the rotating speed of the fan is constant at 10.5 ten thousand revolutions, and the power of the heating wire is constant at 1200W.

If the extracted mode identification code is the identification code corresponding to the cold air mode, the processor can control the blowing equipment to blow air according to the rotating speed of the fan and the power of the heating wire in the preset cold air mode. For example, when the blowing device works in the cold air mode, the rotating speed of the fan is constantly 10.5 thousands of revolutions, and the heating wire is closed.

If the extracted mode identification code is the identification code corresponding to the hair care mode, the processor can control the blowing equipment to blow air to the blowing object according to the preset rotating speed of the fan and the power of the heating wire in the hair care mode. For example, when the blowing device works in the hair care mode, the rotating speed of the fan is constantly 8 thousands of revolutions, and the power of the heating wire is constantly 300W.

In some embodiments, the dryness degree of the blowing object may be displayed to the user through different light emitting colors of two-color LED lamps, for example, the two-color LED lamps include a blue lamp emitting blue light and a red lamp emitting red light, and the processor controls the on and off of the blue lamp and the red lamp by outputting PWM modulation signals of different duty ratios to the blue lamp and the red lamp, respectively.

Referring to fig. 6, fig. 6 is a schematic color adjustment diagram for adjusting the light emitting color of the annular light band according to the return air humidity detection value, where the duty ratio modulation range of the first PWM modulation signal corresponding to the blue light is 0-100%, the duty ratio modulation range of the second PWM modulation signal corresponding to the red light is 0-100%, and the output frequency of the first PWM modulation signal and the output frequency of the second PWM modulation signal are 1Khz.

If the return air humidity detection value is 100%, the duty ratio of the first PWM modulation signal output by the processor is 0, the duty ratio of the second PWM modulation signal is 100%, and at the moment, the red lamp reaches the maximum luminous brightness and the blue lamp does not emit light, so that the fact that the humidity of the blowing object is extremely high is shown.

If the return air humidity detection value is 0, the duty ratio of the first PWM modulation signal output by the processor is 100%, the duty ratio of the second PWM modulation signal is 0, and at the moment, the red lamp does not emit light and the blue lamp reaches the maximum light-emitting brightness to show that the blowing object is in a dry state.

In the blowing process, if the return air humidity detection value is decreased from 100% to the return air humidity upper limit value as 80%, the duty ratio of the second PWM modulation signal is gradually decreased from 100% to 80%, the duty ratio of the first PWM modulation signal is still 0, the blue lamp keeps not emitting light at the stage, and the light emitting brightness of the red lamp is gradually decreased from the maximum light emitting brightness;

if the return air humidity detection value is decreased gradually from the upper limit value of the return air humidity to the lower limit value of the return air humidity, such as 80%, to 20%, the duty ratio of the second PWM modulation signal is gradually decreased from 80% to 0, the duty ratio of the first PWM modulation signal is gradually increased from 0 to 80%, the luminous brightness of the red lamp is gradually decreased at the stage, and the luminous brightness of the blue lamp is gradually increased;

the return air humidity detection value is decreased to 0 from the lower limit value of the return air humidity, such as 20%, the duty ratio of the first PWM modulation signal is gradually increased to 100% from 80%, the duty ratio of the second PWM modulation signal is maintained to be 0, the red lamp is kept not to emit light at the stage, and the light emitting brightness of the blue lamp gradually reaches the maximum light emitting brightness.

In the embodiment of the application, the display of the dryness and wetness degree of the blowing object is realized by the double-color LED color gradient display method, so that a user can clearly know the blowing process, and the user experience is improved.
