Description

Technical Field

[0001] The present application relates to the technical field of drying devices, and in particular to a method and system for testing the hair drying speed of a drying device. Background Art

[0002] In a drying device, such as a hair dryer, the airflow is mainly used to dry the washed hair of the user, and the wind speed is the main factor that directly affects the hair drying speed. It is generally believed that the greater the wind speed, the faster the hair drying speed. However, after the wind speed exceeds a certain value, the degree of improvement in the hair drying speed is not obvious, but it will bring about problems such as noise and power consumption. In addition, during the hair drying process, the moisture on the surface of the hair gradually decreases, so even if the same wind speed is used at different times during the hair drying process, the hair drying speed is different. However, the test method in the related art can only measure the average hair drying speed during the entire hair drying time, and cannot test the hair drying speed at different times during the hair drying process. Summary of the invention

[0003] The embodiments of the present application provide a method and a system for testing the hair drying speed of a drying device.

[0004] The embodiment of the present application provides a method for testing the hair drying speed of a drying device. The testing method comprises: step 1: providing a sample hair soaked in a liquid, the weight of the sample hair being a preset first weight; step 2: performing a blow-drying operation on the sample hair through the drying device, obtaining the change of the weight of the sample hair over time during the blow-drying process, and the drying time taken for the weight of the sample hair to reach a preset second weight, wherein the second weight is less than the first weight; and step 3: generating an evaluation model for characterizing the hair drying speed of the drying device according to the drying time and the change of the weight of the sample hair over time during the blow-drying process.

[0005] The embodiment of the present application also provides a testing system for the hair drying speed of a drying device. The testing system includes: a testing platform, a fixing fixture, a drying device and a processor. The fixing fixture is installed on the testing platform, and the fixing fixture is used to install sample hair. The drying device is used to blow the sample hair soaked in liquid and having a preset first weight. The processor is used to obtain the change of the weight of the sample hair over time during the blowing process, and the drying time consumed for the weight of the sample hair to reach a preset second weight, wherein the second weight is less than the first weight, and the processor is also used to generate an evaluation model for characterizing the hair drying speed of the drying device according to the drying time and the change of the weight of the sample hair over time during the blowing process.

[0006] The hair drying speed test method and test system of the drying device in the embodiment of the present application records the weight change of the sample hair over time during the hair drying process, and generates an evaluation model for characterizing the hair drying speed of the drying device according to the hair drying time and the weight change of the sample hair over time during the hair drying process.

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0023] See also Figure 1 and Figure 2 The embodiment of the present application provides a method for testing the hair drying speed of a drying device 10. The testing method includes:

[0024] 01 (step 1): providing a hair sample soaked in a liquid, wherein the weight of the hair sample is a preset first weight;

[0025] 02 (Step 2): Blowing the sample hair with a drying device to obtain the weight change of the sample hair over time during the blowing process, and the drying time required for the weight of the sample hair to reach a preset second weight, wherein the second weight is less than the first weight; and

[0026] 03 (Step 3): Generate an evaluation model for characterizing the hair drying speed of the drying device according to the drying time and the change in the weight of the sample hair during the blow-drying process.

[0027] The method for testing the hair drying speed of the drying device in the embodiment of the present application records the weight change of the sample hair over time during the hair blowing process, and generates an evaluation model for characterizing the hair drying speed of the drying device according to the hair drying time and the weight change of the sample hair over time during the hair blowing process. In the evaluation model, the hair drying speed at any time in the record can be evaluated according to the weight change, and the greater the weight change, the faster the hair drying speed. In this way, the hair drying speed at different times during the hair blowing process can be obtained through the evaluation model.

[0028] It should be noted that the first weight and the second weight are preset. When the weight of the sample hair is the first weight, it can simulate the hair of the user who starts to blow-dry the hair using the drying device 10 after washing the hair, that is, simulate the wet hair after washing the hair; when the weight of the sample hair is the second weight, it can simulate the hair of the user who completes the blow-drying operation using the drying device 10, that is, simulate the dry hair after blowing the hair. In addition, the sample hair can be a hair piece or a hair bundle, which is not limited here.

[0029] Specifically, see Figure 1 and Figure 3 In some embodiments, step 01: providing a hair sample soaked in a liquid, the weight of the hair sample being a preset first weight, comprises:

[0030] 011 (step 11): immerse the sample hair in the liquid and then take it out;

[0031] 012 (Step 12): Drain the hair sample soaked with liquid until the weight of the hair sample reaches a first weight.

[0032] For example, in some embodiments, the sample hair is soaked in liquid and then taken out, so that the sample hair can be wet to simulate the wet hair of the user just after washing. The liquid soaking the sample hair can be clean water, or a liquid mixed with toiletries (including but not limited to at least one of shampoo and conditioner), etc., which is not limited here.

[0033] It should be noted that the sample hair may be immersed in the liquid first, and then the sample hair soaked in the liquid may be mounted on the fixed fixture 30 (eg Figure 2 Of course, in some embodiments, the sample hair may be tensioned and mounted on the fixed fixture 30 first, and then the fixed fixture 30 with the sample hair mounted thereon may be immersed in the liquid. After the fixed fixture 30 with the sample hair mounted thereon is immersed in the liquid, the fixed fixture 30 may be driven to move in the liquid. In this way, the sample hair on the fixed fixture 30 can be wetted more evenly, so that the wetted sample hair is closer to the user's hair after washing, which is beneficial to improving the accuracy of the test. Among them, the movement of the fixed fixture 30 in the liquid includes but is not limited to at least one of swinging, rotating, and up / down pulling. Since it is difficult to precisely quantify the weight of the sample hair during the wetting process of the sample hair, it is impossible to make the sample hair reach the first weight directly after wetting, so a draining operation after wetting is added so that the sample hair can slowly reach the first weight and accurately determine the start time of the test.

[0034] After obtaining the hair sample soaked with liquid, the hair sample soaked with liquid is drained until the weight of the hair sample reaches a first weight, thereby simulating that the user is ready to use the drying device 10 ( Figure 2 For details, please refer to Figure 3 and Figure 4 In some embodiments, step 12: draining the hair sample soaked with liquid until the weight of the hair sample reaches a first weight, comprises:

[0035] 0121: performing a dehumidification operation on the surface of the hair sample until the weight of the hair sample reaches a predetermined weight, and the predetermined weight is greater than the first weight; and

[0036] 0122: After the dehumidification operation, the hair sample is naturally drained until the weight of the hair sample reaches the first weight.

[0037] In some embodiments, after obtaining a hair sample soaked with liquid, a dehumidification operation is actively performed on the surface of the hair sample until the weight of the hair sample reaches a predetermined weight, wherein the predetermined weight is greater than the first weight. This can reduce the weight of the hair sample after soaking, and is conducive to reducing the time for the hair sample to drain to the first weight.

[0038] In particular, in some embodiments, the weight of the sample hair is recorded according to the cycle of the dehumidification operation, that is, after the dehumidification structure completes a cycle of the dehumidification operation on the sample hair, the weight of the sample hair is recorded once. In this way, it can be avoided that the weight of the sample hair is lower than the first weight due to excessive dehumidification, resulting in test failure. By way of example, in some embodiments, the dehumidification structure may include an absorbent towel, which performs a dehumidification operation on the surface of the sample hair by absorbing water droplets on the surface of the sample hair. At this time, if the sample hair is a hair piece, the absorbent towel absorbs water once on both the front and back sides of the hair piece, which is a dehumidification cycle; if the sample hair is a hair bundle, the absorbent towel absorbs water once on a whole circle of the hair bundle, which is a dehumidification cycle. Taking the sample hair as a hair piece as an example, after obtaining a hair piece soaked with liquid, the absorbent towel absorbs water once on both the front and back sides of the hair piece, and then measures the weight of the sample hair. If the weight of the sample hair is greater than the predetermined weight at this time, the front and back sides of the hair piece are again absorbed by the absorbent towel, and the above steps are repeated until the weight of the sample hair is measured to be equal to the predetermined weight, and the dehumidification operation of the hair piece can be stopped. Of course, in some embodiments, the dehumidification structure can also include a roller structure (such as a single-sided roller structure or a double-sided roller structure), and the rollers in the roller structure press the sample hair and roll to perform a dehumidification operation on the surface of the sample hair, which is not limited here. It is easy to understand that the various weights mentioned above are a certain range of values, rather than specific precise values. After the weight of the sample hair enters the range, it can be considered that the sample hair has reached the corresponding weight.

[0039] After the dehumidification operation of the sample hair is completed, that is, the weight of the sample hair reaches the predetermined weight, the sample hair after the dehumidification operation is naturally drained until the weight of the sample hair reaches the first weight. When the weight of the sample hair reaches the first weight, it can be considered that the degree of moisture of the sample hair at this time is roughly the same as the degree of moisture of the hair when the user starts to blow-dry the hair using the drying device 10 after washing the hair in real life.

[0040] After the sample hair soaked with liquid is drained until the weight reaches the first weight, the sample hair is blown by the drying device 10, and the weight change of the sample hair over time during the blowing process is recorded. Figure 2 and Figure 5 In some embodiments, obtaining the change in weight of the sample hair over time during the hair blowing process includes:

[0041] 021: The weight and time changes of the sample hair are recorded once in each blowing cycle, and the blowing cycle is when the drying device 10 blows on the surface of the sample hair.

[0042] More specifically, see Figure 6 and Figure 7 In some embodiments, the sample hair is a hair piece, and the hair piece includes a first side a and a second side b; each hair blowing cycle records the weight and time changes of the sample hair, including:

[0043] 022: recording the first starting time when the drying device 10 starts blowing the first surface a and the first ending time when the drying device 10 finishes blowing the first surface a;

[0044] 023: Pause the recording time, the drying device 10 and the hair piece rotate relative to each other;

[0045] 024: Record the second starting time when the drying device 10 starts blowing the second surface b and the second ending time when the drying device 10 finishes blowing the second surface b, and

[0046] 025: Record the weight of the sample at the second end time.

[0047] For example, see Figure 7 The sample hair is a hair piece, and the hair piece includes a first surface a and a second surface b opposite to it. First, the side of the fixing tool 30 corresponding to the first surface a of the hair piece is oriented toward the drying device 10, that is, the first surface a of the hair piece is oriented toward the drying device 10. The drying device 10 blows the first surface a of the hair piece, and records the first starting time when the drying device 10 starts to blow the first surface a and the first ending time when the first surface a is blown. Then, the recording time is paused, and the drying device 10 and the hair piece are rotated relative to each other. When the side of the fixing tool 30 corresponding to the second surface b of the hair piece is oriented toward the drying device 10, that is, the second surface b of the hair piece is oriented toward the drying device 10, the drying device 10 blows the second surface b of the hair piece again, and records the second starting time when the drying device 10 starts to blow the second surface b and the second ending time when the second surface b is blown, and the weight of the sample hair at the second ending time is recorded. The drying device 10 rotates relative to the hair piece. In one example, the drying device 10 may remain stationary, and the fixing tool 30 drives the hair piece mounted thereon to rotate; in another example, the hair piece may remain stationary, and the drying device 10 moves to the other side of the hair piece, which is not limited here.

[0048] It should be noted that the drying device 10 blows the first side a of the hair piece once and blows the second side b of the hair piece once, which is a blowing cycle. In this embodiment, the duration of a blowing cycle needs to exclude the time during which the drying device 10 and the hair piece rotate relative to each other. In other words, the duration of a blowing cycle is the sum of the time difference between the first starting moment and the first ending moment, and the time difference between the second starting moment and the second ending moment. For example, assuming that the blowing of the first side a of the hair piece starts at the first minute and ends at the second minute; the blowing of the second side b of the hair piece starts at the fifth minute and ends at the sixth minute, the duration of a blowing cycle is two minutes.

[0049] Since the relative rotation of the drying device 10 and the hair piece is only for the drying device 10 to blow the hair piece more evenly, this operation does not exist when the user actually uses the drying device 10 to blow the hair. In this way, the time during which the drying device 10 and the hair piece rotate relative to each other is not counted in the blowing time, which can improve the accuracy of the test.

[0050] In particular, in some embodiments, if the area of ​​the hair piece is very large, so that the drying device 10 can only cover a part of the hair piece, the drying device 10 is first set at a position corresponding to the top of the first side c of the hair piece, and the drying device 10 is turned on, so that the drying device 10 is moved from the first side c of the hair piece to the second side d while performing a hair blowing operation, and the time length of the drying device 10 moving from the first side c of the hair piece to the second side d is recorded. Then, the drying device 10 is turned off, and the drying device is moved downward by a preset distance, and then the drying device 10 is turned on again, so that the drying device 10 is moved from the second side d of the hair piece to the first side c while performing a hair blowing operation, and the time length of the drying device 10 moving from the second side d of the hair piece to the first side c is recorded, and the above steps are repeated until the drying device 10 traverses the first side a of the hair piece. After completing one blowing of the first side a of the hair piece, the drying device 10 rotates relative to the hair piece, and the drying device 10 repeats the above steps to traverse the second side b of the hair piece. In this way, a hair-blowing cycle is completed. At this time, the duration of the hair-blowing cycle not only does not include the time during which the drying device 10 and the hair piece rotate relative to each other, but also does not include the time during which the drying device 10 moves downward relative to the hair piece, which can further improve the accuracy of the test.

[0051] See also Figure 8 In some embodiments, the sample hair is a hair bundle; and the weight and time changes of the sample hair are recorded once in each hair-drying cycle, including:

[0052] 026: recording the start time when the drying device 10 starts blowing the hair bundle; 027: the drying device 10 rotates relative to the hair bundle, and recording the end time when the drying device 10 stops blowing the hair bundle; and

[0053] 028: Record the weight of the hair bundle at the end moment.

[0054] For example, in some embodiments, the sample hair is a hair bundle. First, the initial position of the hair bundle is set corresponding to the drying device 10, and then the drying device 10 is turned on to blow the hair bundle, and the starting time when the drying device 10 starts to blow the hair bundle is recorded. The drying device 10 rotates relative to the hair bundle. During the rotation process, the drying device 10 continues to blow the hair bundle. When the initial position of the hair bundle corresponds to the drying device 10 again, it means that the drying device 10 has completed a full circle of blowing on the hair bundle, that is, a blowing cycle is completed, and the drying device 10 ends the blowing of this blowing cycle. The end time when the drying device 10 ends blowing the hair bundle is recorded, and the weight of the hair bundle at the end time is recorded. Among them, the drying device 10 rotates relative to the hair bundle. In one example, the drying device 10 can remain stationary, and the fixed tooling 30 can drive the hair bundle installed thereon to rotate; in another example, the hair bundle can remain stationary, and the drying device 10 can rotate relative to the hair bundle, which is not limited here.

[0055] It should be noted that in the above-mentioned hair piece and hair bundle embodiments, since the continuous blowing of the drying device 10 is equivalent to applying external force to the sample hair, if the weight of the sample hair is directly measured when the wind has not completely stopped, it will be disturbed by the wind, and the first weight at the beginning is obtained by testing the sample hair without being affected by the wind, resulting in errors in weight comparison. In order to avoid the influence of wind on the weight test, when recording the weight of the sample hair at the end time, it is necessary to first record the end time of stopping the blowing, and then pause for a period of time until the influence of the wind on the sample hair completely disappears, and then test the weight of the sample hair and record it as the weight at the end time.

[0056] After recording the weight of the sample hair once in each hair blowing cycle, the obtained weight of the sample hair is compared with the preset second weight. If the weight of the sample hair is greater than the second weight, the next hair blowing cycle is performed until the weight of the sample hair reaches the second weight. When the weight of the sample hair reaches the second weight, the hair drying time is recorded. The time taken for the weight of the sample hair to reach the second weight from the first weight is recorded as the hair drying time. It should be noted that the hair drying time also does not take into account the time the drying device 10 waits outside the sample hair (for example, when the sample hair is a hair piece, the time during the relative motion between the drying device 10 and the hair piece). In some embodiments, the hair drying time is an integer multiple of the hair blowing cycle.

[0057] In particular, during the test, it is possible that when the weight of the sample hair is greater than the second weight after the last blow-drying cycle, and after the next blow-drying cycle, the weight of the sample hair is less than the second weight. That is to say, the moment when the weight of the sample hair reaches the second weight may be within the blow-drying cycle. In some embodiments, when the difference between the weight of the sample hair and the second weight is measured to be within the first preset range after a blow-drying cycle is completed, it is assumed that the weight of the sample hair has reached the second weight at this time, and the drying device 10 stops blowing the sample hair. In some embodiments, when the weight of the sample hair is greater than the second weight after a blow-drying cycle is completed, and the difference between the weight of the sample hair and the second weight is within the second preset range, the next blow-drying cycle is performed, and the change of the weight of the sample hair over time is recorded during the blow-drying cycle. When the weight of the sample hair is equal to the second weight, the drying device 10 is stopped immediately, and the moment when the weight of the sample hair is equal to the second weight is recorded. In this way, a more accurate drying time can be obtained, which is beneficial to the accuracy of the test.

[0058] Of course, in some embodiments, after the sample hair soaked with liquid is drained until the weight reaches the first weight, the sample hair is blown by the drying device 10, and the weight change of the sample hair over time during the blowing process can be recorded in real time, that is, the weight of the sample hair at each moment is recorded until the weight of the sample hair reaches the second weight. In some embodiments, the weight of the sample hair can be recorded at intervals of a preset time, or the weight of the sample hair can be recorded at multiple moments randomly selected, without having to record the weight of the sample hair after a complete blowing cycle, which is not limited here.

[0059] After obtaining the hair drying time, the weight of the sample hair during the hair blowing process and the corresponding time, in some embodiments, an evaluation model for characterizing the hair drying speed of the drying device 10 can be generated according to the hair drying time and the change of the sample hair over time during the hair blowing process. For example, in some embodiments, the average hair drying speed of the drying device 10 during the hair blowing process can be obtained by directly dividing the hair drying time by the weight difference between the second weight and the first weight.

[0060] See also Fig. 9 In some embodiments, the evaluation model can be a drying speed curve with time as the horizontal axis and sample hair weight as the vertical axis. The drying speed curve is a curve fitted with the blowing time as the horizontal axis and the sample hair weight as the vertical axis. The slope of the tangent line at any point on the drying speed curve is used to characterize the drying speed at the corresponding moment. In this way, the drying speed corresponding to each moment in the drying process can be obtained. It should be noted that the moment on the horizontal axis refers to the time each time the drying device 10 is turned on for blowing.

[0061] For example, in some embodiments, a plurality of calibration points are marked according to the weight obtained during the hair drying process and the corresponding time, and then a smooth curve is used to fit the plurality of calibration points into a smooth curve, so as to obtain a hair drying speed curve. Fig. 9 As shown, it is assumed that in the process of blowing the sample hair, at time t0, the weight of the sample hair is the first weight; at time t1, the weight of the sample hair is g1; at time t2, the weight of the sample hair is g2; at time t3, the weight of the sample hair is g3; at time t4, the weight of the sample hair is the second weight. Then, according to the weights obtained above and their corresponding times, multiple calibration points are marked, where point A corresponds to time t0 and the first weight, point B corresponds to the weight g1 at time t1, point C corresponds to the weight g2 at time t2, and point D corresponds to the second weight at time t4. Subsequently, a smooth curve is used to fit the multiple calibration points into a smooth curve, so that the hair drying speed curve is obtained. Of course, the evaluation model can also be expressed in other forms. For the convenience of explanation, the following embodiment takes the evaluation model as a hair drying speed curve as an example for explanation.

[0062] In particular, in some embodiments, the hair drying speed corresponding to each moment can also be obtained by the weight difference between the weight of the hair sample at this moment and the weight of the hair sample at the previous moment, and the time difference between this moment and the previous moment. For example, at moment t1, the weight of the hair sample is g1; at moment t2, the weight of the hair sample is g2, then the hair drying speed corresponding to moment t2 is s=(g1-g2) / (t2-t1), so another evaluation model can be generated.

[0063] See also Fig.10 In some embodiments, the testing method further comprises:

[0064] 06: Using drying devices 10 of different models, under the same operating conditions, repeat steps 1 to 3 to generate multiple hair drying speed evaluation models corresponding to the drying devices 10 of different models.

[0065] In some embodiments, different models of drying devices 10 may be used, and the same operating conditions may be used to repeatedly perform steps 1 to 3 in the above embodiment to generate multiple hair drying speed evaluation models corresponding to each model of drying device 10. In this way, the quality of the hair drying speed of different models of drying devices 10 at different times under the same operating conditions can be obtained.

[0066] It should be noted that the operating conditions include operating parameters of each component in the drying device 10, and the operating parameters include at least one of the motor speed of the airflow element, the voltage of the radiation source, and the power of the heating component. Different models of drying devices 10 are operated using the same operating conditions, that is, different models of drying devices 10 use the same operating parameters to perform a hair drying operation on the sample hair.

[0067] For example, see Fig.11 , taking the drying devices 10 of different models, the operating conditions adopted are: the motor of the airflow element works at the maximum speed, the radiation source works at the maximum voltage, and the heating component works at the maximum power as an example. The speed of the motor of the airflow element of the drying device 10 of the first model I is adjusted to the maximum speed, the voltage of the radiation source is adjusted to the maximum voltage, and the power of the heating component is adjusted to the maximum power, and the above steps 1 to 3 are performed to generate an evaluation model corresponding to the drying device 10 of the first model I ( Fig.11 The solid line shown in ); then the speed of the motor of the airflow element of the drying device 10 of the second model II is adjusted to the maximum speed, the voltage of the radiation source is adjusted to the maximum voltage, and the power of the heating component is adjusted to the maximum power, and the above steps 1 to 3 are repeated to generate an evaluation model corresponding to the drying device 10 of the second model II ( Fig.11 The speed of the motor of the airflow element of the drying device 10 of the third model III is adjusted to the maximum speed, the voltage of the radiation source is adjusted to the maximum voltage, and the power of the heating component is adjusted to the maximum power, and the above steps 1 to 3 are repeated to generate an evaluation model corresponding to the drying device 10 of the third model III ( Fig.11 dot-dash line shown in ).

[0068] See also Fig.12 In some embodiments, the testing method further comprises:

[0069] 07: The drying device 10 repeats steps 1 to 3 under various operating conditions to generate multiple hair drying speed evaluation models corresponding to each operating condition. The operating conditions include operating parameters of each component in the drying device 10, and the operating parameters include at least one of the motor speed of the airflow element, the voltage of the radiation source, and the power of the heating component.

[0070] In some embodiments, the drying device 10 can be adjusted to adopt different operating conditions, and steps 1 to 3 can be repeatedly performed to generate multiple evaluation models of hair drying speeds corresponding to the operating conditions. In this way, the quality of the hair drying speed when the same drying device 10 is used for hair drying operations under different operating conditions at different times can be obtained. It should be noted that the operating conditions include operating parameters of each component in the drying device 10, and the operating parameters include at least one of the airflow element motor speed, the radiation source voltage, and the heating component power.

[0071] For example, see Fig.13, take the first operating condition as an example: the motor of the airflow element is at the maximum speed, the radiation source is at the maximum voltage, and the heating component is at the maximum power; the second operating condition is: the motor of the airflow element is at the maximum speed, the radiation source is at 80% of the maximum voltage, and the heating component is at 60% of the maximum power; the third operating condition is: the motor of the airflow element is at 80% of the maximum speed, the radiation source is at 80% of the maximum voltage, and the heating component is at 80% of the maximum power. First, adjust the speed of the motor of the airflow element of the drying device 10 to the maximum speed, the voltage of the radiation source to the maximum voltage, and the power of the heating component to the maximum power, and perform the above steps 1 to 3 to generate an evaluation model corresponding to the first operating condition ( Fig.13 The speed of the motor of the airflow element of the drying device 10 is adjusted to the maximum speed, the voltage of the radiation source is adjusted to 80% of the maximum voltage, and the power of the heating component is adjusted to 60% of the maximum power, and the above steps 1 to 3 are repeated to generate an evaluation model corresponding to the second operating condition ( Fig.13 The speed of the motor of the airflow element of the drying device 10 is adjusted to 80% of the maximum speed, the voltage of the radiation source is adjusted to 80% of the maximum voltage, and the power of the heating component is adjusted to 80% of the maximum power, and the above steps 1 to 3 are repeated to generate an evaluation model corresponding to the third operating condition ( Fig.13 dot-dash line shown in ).

[0072] It should be noted that in Fig.11 and Fig.13 In the hair drying curve diagram shown in , the curves corresponding to the various evaluation models do not intersect, that is, the hair drying speed of the curve located above the diagram is always higher than that of the curve located below the diagram. In actual tests, the curves may intersect, which can be understood as follows: in some stages, the hair drying speed of a certain model of drying device 10 or a certain working condition of the drying device 10 is faster, but in other stages, it is slower than the hair drying speed of other models of drying devices 10 or other working conditions of the drying device 10. In other words, the hair drying speed of different models of drying devices 10 or different working conditions of the drying device 10 at each stage or time can be quantitatively evaluated and studied according to the evaluation model.

[0073] In particular, since environmental parameters (including temperature and / or humidity) also affect the drying speed of the drying device 10, that is, under different environmental parameters, even if the drying device 10 uses the same operating conditions at the same time, the hair drying speed will be different. Therefore, in some embodiments, the evaluation model of the hair drying speed corresponds to the environmental parameters, and the evaluation model is marked with the environmental parameters corresponding to the evaluation model (such as Fig.13 upper right corner), for example Fig.13 ,express Fig.13 The drying speed curve in is obtained under the conditions of a temperature of 26 degrees Celsius and a humidity of 20% RH. In addition, in some embodiments, the test method further includes: under different environmental parameters, the drying device 10 adopts the same operating condition, and repeatedly performs steps 1 to 3 to generate multiple drying speed evaluation models corresponding to each operating condition.

[0074] See also Fig.14 In some embodiments, the testing method further comprises:

[0075] 08: The drying device 10 adopts different operating conditions at different time periods, and repeatedly executes steps 1 to 3 to generate multiple evaluation models of hair drying speeds corresponding to each operating condition and each time period. The operating conditions include operating parameters of each component in the drying device 10, and the operating parameters include at least one of the motor speed of the airflow element, the voltage of the radiation source, and the power of the heating component.

[0076] In some embodiments, the operating conditions of the drying device 10 can also be adjusted during the hair blowing process, so that the drying device 10 adopts different operating conditions at different time periods, and steps 1 to 3 are repeatedly performed to generate multiple evaluation models of hair drying speeds corresponding to each operating condition and each time period. In this way, the quality of the hair drying speed when the drying device 10 adopts the corresponding operating conditions for hair blowing operations at different time periods can be obtained. It should be noted that the operating conditions include the operating parameters of each device in the drying device 10, and the operating parameters include at least one of the airflow element motor speed, the radiation source voltage, and the heating component power.

[0077] For example, see Fig.15 , take the first operating condition as an example: the motor of the airflow element is at the maximum speed, the radiation source is at the maximum voltage, and the heating component is at the maximum power; the second operating condition is: the motor of the airflow element is at the maximum speed, the radiation source is at 80% of the maximum voltage, and the heating component is at 60% of the maximum power; the third operating condition is: the motor of the airflow element is at 80% of the maximum speed, the radiation source is at 80% of the maximum voltage, and the heating component is at 80% of the maximum power, and the first operating condition is used from time t0 to time t1, the second operating condition is used from time t1 to time t2, and the third operating condition is used from time t2 to time t3. First, after adjusting the speed of the motor of the airflow element of the drying device 10 to the maximum speed, the voltage of the radiation source is adjusted to the maximum voltage, and the power of the heating component is adjusted to the maximum power, perform the above steps 1 to 3 to generate a first evaluation model corresponding to the first operating condition ( Fig.15(a) solid line). Then adjust the speed of the motor of the airflow element of the drying device 10 to the maximum speed, adjust the voltage of the radiation source to 80% of the maximum voltage, and adjust the power of the heating component to 60% of the maximum power, and repeat the above steps 1 to 3 to generate a second evaluation model corresponding to the second operating condition ( Fig.15 (a)); then adjust the speed of the motor of the airflow element of the drying device 10 to 80% of the maximum speed, adjust the voltage of the radiation source to 80% of the maximum voltage, and adjust the power of the heating component to 80% of the maximum power, and repeat the above steps 1 to 3 to generate a third evaluation model corresponding to the third operating condition ( Fig.15 Finally, the curve corresponding to the time from t0 to t1 in the first evaluation model, the curve corresponding to the time from t1 to t2 in the second evaluation model, and the curve corresponding to the time from t2 to t3 in the third evaluation model are combined to generate a new curve (as shown in FIG. Fig.15 (b)), that is, generating a hair drying speed evaluation model when the first operating condition is adopted from time t0 to time t1, the second operating condition is adopted from time t1 to time t2, and the third operating condition is adopted from time t2 to time t3.

[0078] In particular, see Fig.16 In some embodiments, step 1 may be performed first, that is, the sample hair soaked with liquid is drained until the weight of the sample hair reaches a preset first weight, and at time t0 (i.e., the start time of the hair blowing operation), the operating condition of the drying device 10 is adjusted to the first operating condition, the hair sample is blown until time t1 is reached, and the weight change of the sample hair between time t0 and time t1 is recorded, and an evaluation model ( Fig.16 When time t1 is reached, the operating condition of the drying device 10 is adjusted to the second operating condition, and the hair sample is blown until time t2 is reached. The weight change of the hair sample over time between time t1 and time t2 is recorded, and an evaluation model ( Fig.16 When time t2 arrives, the operating condition of the drying device 10 is adjusted to the third operating condition, and the hair sample is blown until time t3 is reached. The weight change of the hair sample over time between time t2 and time t3 is recorded, and an evaluation model ( Fig.16 In this way, multiple evaluation models of hair drying speed corresponding to each operating condition and each time period can be directly obtained. Fig.15The embodiment directly adjusts the operating conditions of the drying device 10 during the hair blowing process of the same test, which can reduce the test time and help reduce errors, and is closer to the effect of actual users changing the operating conditions during the hair blowing process.

[0079] See also Figure 2 , the embodiment of the present application also provides a testing system 100 for the hair drying speed of a drying device 10. The testing system 100 includes: a drying device 10, a testing platform 20, a fixing fixture 30 and a processor 40. The fixing fixture 30 is installed on the testing platform 20, and the fixing fixture 30 is used to install sample hair. The drying device 10 is used to blow-dry sample hair that is soaked in liquid and has a preset first weight. The processor 40 is used to obtain the change of the weight of the sample hair over time during the blowing process, and the drying time consumed for the weight of the sample hair to reach a preset second weight. Among them, the second weight is less than the first weight. The processor 40 is also used to generate an evaluation model for characterizing the hair drying speed of the drying device 10 according to the drying time and the change of the weight of the sample hair over time during the blowing process.

[0080] The hair drying speed testing system 100 of the drying device 10 in the embodiment of the present application records the weight change of the sample hair over time during the hair blowing process, and generates an evaluation model for characterizing the hair drying speed of the drying device according to the hair drying time and the weight change of the sample hair over time during the hair blowing process. In this way, the hair drying speed at different moments during the hair blowing process can be obtained.

[0081] It should be noted that, in some embodiments, the test system 100 further includes a timer (not shown), which is used to record the duration of the hair blowing process and the hair drying time. In some embodiments, the test system 100 further includes a sensor 50, which is connected to the fixed fixture 30, and the sensor 50 can measure the weight of the fixed fixture 30 and the sample hair on the fixed fixture 30. Among them, the sensor 50 includes but is not limited to at least one of a gravity sensor, a tension sensor and a stress sensor. In this way, during the process of the drying device 10 performing a hair blowing operation on the sample hair on the fixed fixture 30, the weight of the sample hair can be measured without removing the fixed fixture 30 from the test platform. In addition, the specific implementation of the processor 40 generating the evaluation model of the hair drying speed according to the hair drying time and the change of the weight of the sample hair during the hair blowing process over time is the same as the specific implementation of generating the evaluation model of the hair drying speed according to the change of the hair drying time and the weight of the sample hair during the hair blowing process over time in any of the above embodiments, and will not be repeated here.

[0082] Specifically, see Figure 2In some embodiments, the fixed fixture 30 can be movably mounted on the test platform 20, and the test system can further include a liquid tank 61. The liquid tank 61 is used to hold liquid, and the fixed fixture 30 is used to immerse the sample hair into the liquid in the liquid tank 61 and take out the sample hair immersed in the liquid.

[0083] More specifically, in some embodiments, the test platform 20 includes a bracket 21 and a guide rail 22, the guide rail 22 is installed on the bracket 21, and the fixed tool 30 is installed on the guide rail 22 and can move along the guide rail 22, thereby changing the position of the fixed tool 30 and driving the sample to change its position.

[0084] In a specific embodiment, the fixed tool 30 is installed on the guide rail 22 through the lifting member 23. The lifting member 23 is installed on the guide rail 22 and can move along the guide rail 22, thereby driving the fixed tool 30 to move. The lifting member 23 can be the output end of the linear motor, or can be realized by a screw nut, a belt drive, etc., which will not be described in detail.

[0085] Please continue reading Figure 2 In some embodiments, the liquid tank 61 is disposed below the fixed fixture 30. When the fixed fixture 30 moves down along the guide rail 22, the sample hair installed in the fixed fixture 30 can be immersed in the liquid in the liquid tank 61. After the fixed fixture 30 moves up along the guide rail 22, the liquid tank 61 can catch the liquid dripping from the sample hair immersed in the liquid during the draining operation. By directly immersing the sample hair in the liquid in the liquid tank 61, the sample hair can be quickly wetted.

[0086] For example, the sample hair is tensionedly mounted on the fixed fixture 30, and then the fixed fixture 30 is driven to move down along the guide rail 22 by the lifting member 23, so that the sample hair mounted in the fixed fixture 30 can be immersed in the liquid in the liquid tank 61 to wet the sample hair. Subsequently, the fixed fixture 30 is driven to move up along the guide rail by the lifting member 23, so that the fixed fixture 30 leaves the liquid tank 61, and at the same time, the liquid dripping from the sample hair soaked with liquid during the draining operation can also drip into the liquid tank 61. In this way, the sample hair can be soaked and the liquid dripping from the sample hair during the draining operation can be prevented from dripping into the outside of the test system 100 and contaminating the ground. It should be noted that the liquid in the liquid tank 61 can be clean water, or a liquid mixed with toiletries (including but not limited to at least one of shampoo and conditioner), etc., which is not limited here. The liquid in the following text is also explained in this way and will not be repeated.

[0087] In particular, in some embodiments, the test system 100 may further include a spray device (not shown), which is used to spray liquid onto the sample hair to soak the sample hair installed in the fixing fixture 30. Since the sample hair is soaked by the spray device, compared with directly inserting the sample hair into the liquid tank 61 filled with liquid for wetting, it can avoid excessive wetting of the sample hair so that its weight after soaking far exceeds the preset first weight, thereby reducing the time for the sample hair to drain to the first weight.

[0088] It should be noted that when a spray device is provided in the test system 100, that is, when liquid is sprayed by the spray device to wet the sample hair, in one example, the test platform 20 may not be provided with the guide rail 22 and the lifting member 23, so that the manufacturing cost of the test system 100 can be reduced. When a spray device is provided in the test system 100, that is, when liquid is sprayed by the spray device to wet the sample hair, in one example, the test system 100 may also be provided with a liquid tank 61, which is provided below the fixed fixture 30. At this time, the liquid tank 61 is used to receive the liquid dripped from the sample hair soaked with liquid during the draining operation, so that the dripping liquid can be prevented from dripping into the outside of the test system 100 and contaminating the ground.

[0089] In another embodiment, the spraying device can also serve as a supplement to the liquid tank 61. Compared with immersion, spraying can more accurately control the weight of the hair sample. For example, if the hair sample does not reach the first weight after immersion, appropriate spraying can be used to increase its weight to reach the first weight. Or if the hair sample is drained and is lower than the first weight due to operational problems, spraying can be used to increase its weight to above the first weight.

[0090] Please continue reading Figure 2 In some embodiments, the test platform 20 may further include a driving member 24 disposed on the lifting member 23. The driving member 24 is connected to the fixed fixture 30, and the driving member 24 is used to drive the fixed fixture 30 to rotate. That is, the driving member 24 can drive the fixed fixture 30 to drive the sample hair installed thereon to rotate. On the one hand, the driving member 24 can drive the fixed fixture 30 to drive the sample hair to rotate during the wetting process, so that the sample hair on the fixed fixture 30 can be wetted more evenly, so that the wetted sample hair is closer to the hair of the user after washing the hair, which is conducive to improving the accuracy of the test of the test system 100; on the other hand, the driving member 24 can drive the fixed fixture 30 to drive the sample hair to rotate during the hair blowing operation of the drying device 10, so that the sample hair can be dried evenly, so that the degree of drying of each part of the sample hair is roughly the same, so that the scene when the user actually uses the drying device 10 to blow hair can be better simulated, which is conducive to improving the accuracy of the test of the test system 100.

[0091] In some embodiments, the test platform 20 may further include a dehumidification structure (not shown), which is used to perform a dehumidification operation on the surface of the sample hair soaked with liquid until the weight of the sample hair reaches a predetermined weight, wherein the predetermined weight is greater than the first weight. This can reduce the weight of the sample hair after soaking, which is helpful to reduce the time for the sample hair to drain to the first weight. The dehumidification structure can be installed on the fixed fixture 30 or the bracket 21, which is not limited here.

[0092] For example, in some embodiments, the dehumidification structure may include an absorbent towel. After soaking the sample hair, the absorbent towel with a dehumidification structure is used to absorb the water droplets on the surface of the sample hair to perform a dehumidification operation on the surface of the sample hair. When the weight of the sample hair reaches a predetermined weight, the sample hair is naturally drained until the weight reaches a first weight, and then subsequent operations are performed. In this way, on the one hand, the weight of the sample hair after soaking can be reduced, which is beneficial to reducing the time for the sample hair to drain to the first weight; on the other hand, it can simulate the process of the user using a towel to wipe the water droplets on the surface of the hair after washing the hair before using the drying device 10 to blow dry the hair, which is beneficial to improve the accuracy of the test system 100. Of course, in some embodiments, the dehumidification structure may also include a roller structure (such as a single-sided roller structure or a double-sided roller structure), and the rollers in the roller structure press the sample hair and roll to perform a dehumidification operation on the surface of the sample hair, which is not limited here.

[0093] In some embodiments, the test system 100 may further include a test room (not shown), in which the test platform 20, the fixture 30, and the drying device 10 are all located. The environmental parameters in the test room are adjustable, that is, the drying device 10 can be operated under different environmental parameters. In this way, the test system 100 can test the blowing speed of the drying device 10 under different environmental parameters. It should be noted that the environmental parameters include temperature and / or humidity.

[0094] Please continue reading Figure 2 In some embodiments, the test system 100 further includes an actuator arm 80, and the actuator arm 80 is movable. The actuator arm 80 is used to hold the drying device 10 and drive the drying device 10 to traverse the surface of the sample hair. On the one hand, since there is no need to manually hold the drying device 10 during the hair blowing process, the operating difficulty and labor cost of the test system 100 can be reduced; on the other hand, since the actuator arm 80 can move the drying device 10 to traverse the surface of the sample hair, the sample hair can be dried evenly, so that the degree of dryness of each part of the sample hair is roughly the same, which can better simulate the scene when the user actually uses the drying device 10 to blow hair, which is conducive to improving the accuracy of the test of the test system 100.
