Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below.

In all embodiments of the present disclosure, a beard is taken as an example for explanation. It will be understood by those skilled in the art that the beard of the embodiments of the present disclosure may be human or non-human hair, such as human hair, pet hair, and the like.

Example one

The embodiment of the disclosure provides a test device, which comprises at least one preset area, wherein each preset area is covered with a base layer and beards arranged on the base layer, and the beards are used for simulating human beards needing to be removed by the tested device. The base layer can be made of silica gel. And a plurality of through holes are arranged on the silica gel, and each through hole is used for penetrating at least one beard.

Referring to fig. 1, fig. 1 (a) illustrates a front view of a test apparatus and (b) illustrates a top view of the test apparatus, wherein the test apparatus comprises a structural frame 10; at least one preset area 20 is arranged on the structural frame body 10, and a scene of arranging one preset area 20 is shown in fig. 1, wherein the preset area 20 is covered with a base layer 30 and a beard 40 arranged on the base layer 30. Wherein each of the hairs 40 has the same height from the surface of the base layer 30. In this way, the device under test (e.g., an electric shaver) can shave a beard 40 with the blade perpendicular to the beard according to preset control parameters (described in detail below), resulting in the effect shown in fig. 2. The user can then obtain the efficiency of the device under test based on the beard 40 shown in fig. 2, from which the shaving grade of the device under test can be determined, as will be described in more detail later on, and will not be described in detail here.

In one embodiment, the size of the predetermined area on the test device may be matched to the human beard parameter distribution. The human beard parameter distribution can be obtained by collecting the distribution statistics of the beards of a large number of users on the face, such as rectangle and size, ellipse and size, and the like. Accordingly, the shape of the preset area may be rectangular or elliptical, and of course, the skilled person may determine the preset area and the size thereof in other ways, and the corresponding solutions fall within the scope of the present disclosure. In practical application, the area of the preset area is 9-36 square centimeters. Taking the size of the preset area as a rectangle as an example, the size is a, b, a takes a value of 3-6cm, and b takes a value of 3-6 cm. In one example, the predetermined area may be 5cm by 5cm in size.

In an example, the surface shape of the structural frame corresponding to the preset area may be a plane or an arc, in which case, the base layer may be a layer covering the preset area. When the structural frame body is an arc surface, the preset area forms an arc surface, and the beard also forms an arc surface. In another example, the surface shape of the base layer corresponding to the preset area may be a plane or a cambered surface. For example, when the base layer is a plane, the base layer is directly adhered to the predetermined area, and the surface shape of the base layer changes along with the surface shape of the structural frame. For another example, when the substrate is an arc surface and the structural frame is a plane, a substrate with an arc surface can be directly obtained. It can be understood that when the preset area is an arc surface, the distribution of human beard can be better simulated, and the accuracy of the working efficiency of the tested device can be improved.

In one embodiment, the beard may be made of modified fibers, for example, the modified fibers may include protein functional groups, which may enable the beard to better simulate a human beard, and reduce the effect of the difference between the beard and the beard on the device under test.

In an embodiment, the test device may be recycled, and the height of the hairs 40 may be adjusted after each shaving test to make the height of all the hairs the same, resulting in the effect shown in fig. 1 (a). To this end, in this embodiment, and with reference to fig. 3, the test apparatus further comprises an adjustment device 50, to which adjustment device 50 the hairs 40 are fixed, for example, each hair having one end fixed to the surface of adjustment device 50 and the other end extending beyond base layer 30, so that adjustment device 50 can adjust the height d at which a hair 40 extends beyond base layer 30, and stop after the hair 40 reaches a target height (e.g. 50mm), in preparation for the next shaving test.

In one example, after each shaving test, the user is required to clean the remaining hairs to ensure that all hairs are in the same plane (or curved surface), e.g., so that the individual hairs after removal are flush with the surface of the substrate. Referring to fig. 4, the adjusting device 50 may open and adjust an adjusting assembly 51 in the adjusting device 50. Since the adjustment member 51 has the hair 40 fixed to the surface thereof, the adjustment member 50 can urge the hair to protrude from the base layer 30 until the target height d is reached, as shown in fig. 4.

In another example, referring to fig. 5, the adjustment device 50 may comprise a plurality of adjustment assemblies 51, each adjustment assembly 51 may be individually controlled, and the height of each hair may be adjusted by raising or lowering. Based on this, after each test, the adjustment device 50 calculates the length of each hair, and then controls the adjustment assembly 51 corresponding to each hair to be raised or lowered, respectively, so that the height of each hair is d. It will be appreciated that, due to the limited range of motion of each adjustment assembly 51, a calibration operation can be carried out after a certain number (for example 3-5) of shaving tests: each adjusting component 51 is moved to the same plane, the length of each beard extending out of the base layer 30 is different, after the beards outside the base layer 30 are completely removed, all the sub-adjusting components 51 are simultaneously controlled to ascend, so that the heights of all the beards are the same, namely, the target height d is reached, and the beard effect is shown in fig. 4.

In one embodiment, the adjustment device 50 also adjusts the density with which the hairs extend out of the substrate. The adjusting device 50 includes a plurality of adjusting components, each of which is used for adjusting and setting the height of the root hair. With continued reference to fig. 5, when the respective adjustment elements are controlled to be raised or lowered, respectively, a portion of the beard hairs may be extended out of the base layer and a portion of the beard hairs may not be extended out of the base layer, thereby achieving adjustment of the density of the beard hairs located outside the base layer. In an example, the adjustment device 50 may use each row, each column or each ring-shaped beard as a control unit, and adjust the beard of each control unit. For example, in fig. 6, the whiskers in each column 53 and/or whiskers in each row 54 may be adjusted to achieve the effect of adjusting the density.

It should be noted that each adjusting assembly can be realized by including a movable head, a connecting rod and a driving device, wherein the driving device can be realized by adopting a stepping motor, and the stepping motor can drive the connecting rod to drive the movable head to move when rotating, so as to adjust the height of the beard. In consideration of the control effect, the volume of the driving device and other factors, in practical application, one or more driving devices can be combined in each row, each column and each ring, so that the effects of reducing the number of the driving devices and reducing the volume of the testing equipment are achieved.

In one embodiment, the test device may further comprise a base layer of a plurality of skins, each skin having a different density of through holes. Therefore, the user can adjust the density of the beard by replacing the base layer of the through holes with different densities.

In an embodiment, the test device may comprise a surface roughness measurement instrument, with which the roughness of the beard may be measured after shaving of the device under test. The roughness can then be used to obtain the operating efficiency of the device under test.

In an embodiment, the testing device may comprise a measuring ruler, with which the length and/or area of the beard can be measured after shaving by the device under test. The length and/or area may then be used to obtain the operating efficiency of the device under test.

So far, the embodiment of the present disclosure may cover the base layer and the beard arranged on the base layer on the preset area by providing the preset area on the structural frame body of the test device. Therefore, the beard can be used for simulating the human beard needing to be eliminated by the tested equipment, and the working efficiency of the tested equipment is convenient to obtain.

The embodiment of the present disclosure further provides a detection method, referring to fig. 7, including steps 71 to 73:

in step 71, the length of each individual hair is acquired after the device under test has performed a shaving operation on the hair on the test device.

In this embodiment, after the test device has adjusted the beard, the test device may display a prompt for preprocessing the device under test. Wherein the prompt message may include:

(5) placing the tested equipment to cool to room temperature;

(6) repeating the steps (1) to (5) for 2-3 times.

In the step (3), the tested device is placed on the surface of the soft material, so as to avoid the influence of vibration on the tested device in the working process of the tested device, i.e. avoid the influence of improper testing process on the testing result. And (4) repeating the step (6) for 2-3 times so as to ensure that the tested equipment can work reliably.

After the pretreatment is finished, the tool bit of the tested device can be perpendicular to the beard, and the tested device is started to carry out a simulated shaving test. The test parameters are as follows: speed 5mm/s, time 5 min. After 5min was reached, the test was stopped. Wherein, the speed can be selected between 5-20mm/s, which is not limited herein.

At this time, the tester can measure the length of each beard by using the measuring scale, so as to obtain the length of each beard.

In step 72, the area of the beard at each length level is determined based on the length.

In this embodiment, the area of each beard in each length class may be determined according to the length of each beard, including:

in one example, the beard length can be preset in a grade, such as 0 th grade, and the length range is 0-0.5 mm; grade 1, the length range is 0.5-1.5 mm; grade 2, the length range is 1.5-2.5 mm; grade 3, the length range is 2.5-3.5 mm; grade 4, the length range is 3.5-4.5 mm; grade 5, the length range is 4.5-5 mm. It is understood that the beard length level can be set according to a specific scene, and is not limited herein. Referring to fig. 8, in step 81, preset beard length levels may be acquired, and then based on the beard length levels, the number of beards at each length level may be acquired. In step 82, the area corresponding to a preset single beard may be obtained, and the area corresponding to each length level may be obtained based on the area corresponding to the single beard and the number obtained in step 81.

In another example, referring to fig. 9, in the case where the length of each beard is known, a three-dimensional figure may be constructed based on the surface of the base layer as a reference. After the surface of the substrate is transformed into a plane, the heights of the detection points in the preset area can be obtained, and a three-dimensional graph as shown in fig. 10 is further fitted. In step 92, the area of the section of the three-dimensional image corresponding to each length level may be obtained based on the preset length level of the beard, so as to obtain the area under each length level. For example, a plane (or curved surface) with a distance of 0.5mm, 1.5mm, 2.5mm, 3.5mm, 4.5mm and 5mm is determined in a direction perpendicular to the base layer with the surface of the base layer as a starting point, so that the contour lines shown at the bottom of fig. 10 enclose a closed area, such as areas 0-5. And then, calculating the area of the closed region or calculating the area of the closed region and then removing the inner closed region, for example, when calculating the area of the region 1, firstly calculating the area of the closed region surrounded by the external contour lines, and then subtracting the area of the region 0, wherein the area calculation of other regions is similar.

In step 73, the operating efficiency of the device under test is determined based on the area under each length level.

In this embodiment, the working efficiency of the device under test may be determined based on the area under each length level, referring to fig. 11, in step 111, a preset area of a preset region in the test device may be obtained, for example, 5cm by 5cm to 2500mm²Then, the ratio of the area under each length grade to the preset area is obtained, and the formula is as follows:

In step 112, a level of operating efficiency may be determined based on the ratio corresponding to each length level. In one example, the levels include AAA, AA, and A levels, and the length level is level 6, as shown in Table 1. The content of 99%, 80%, and 50% may be set as appropriate, and is not limited herein.

TABLE 1 class of work efficiency

Shaving efficiency rating	Basis of grade determination
		AAA level	P₀≥99％、(P₁+P₂+P₃+P₄+P₅＝0)
Grade AA	P₀≥80％、P₁＜20％(P₂+P₃+P₄+P₅＝0)
		Class A	P₀≥50％、P₁+P₂＜50％(P₃+P₄+P₅＝0)

In this way, it can be determined that the device under test belongs to AAA, AA, a or off-spec products.

Example two

The disclosed embodiment provides a test device, which is based on the test device shown in fig. 1-7, and further comprises a signal conducting device; the signal conduction device can be arranged in the structural frame body and electrically connected with each beard, and is used for sending detection signals to each beard and acquiring the length of each beard according to feedback signals of the detection signals. Wherein, the base layer can be made of silica gel. And a plurality of through holes are arranged on the silica gel, and each through hole is used for penetrating at least one beard.

Referring to fig. 12, in fig. 12 (a) illustrates a front view of a test apparatus, (b) illustrates a top view of the test apparatus, wherein the test apparatus comprises a structural frame 10; the structural frame 10 is provided with a predetermined area 20, and the predetermined area 20 is covered with a base layer 30 and a beard 40 provided on the base layer 30. Wherein each of the hairs 40 has the same height from the surface of the base layer 30. In this way, the device under test (e.g., an electric shaver) can shave a beard 40 with the blade perpendicular to the beard according to preset control parameters (described in detail below), resulting in the effect shown in fig. 2. The signal conducting means 60 are then arranged inside the structural frame 10, so that the length of the beard 40 shown in fig. 2 can be obtained, which can be used to obtain the working efficiency of the device under test and to determine the shaving grade of the device under test according to the working efficiency, which will be described in detail later and will not be described herein.

In one embodiment, the beard may be made of conductive fibers, and 1 or 2 wires may be disposed inside the conductive fibers. Taking 2 conductors of the first conductor and the second conductor as an example, the output end of the signal conducting device 60 is electrically continuous with the first conductor, and the receiving end of the signal conducting device 60 is electrically continuous with the second conductor; when the end of the beard remote from the signal conducting means 60 is coated with a conductive layer, the output terminal, the first conducting wire, the conductive layer, the second conducting wire and the receiving terminal constitute a detection loop. In this way, the signal transmission device 60 can calculate the length of each beard according to the sending time of the electrical detection signal, the receiving time of the feedback signal of the electrical detection signal and the preset reference time.

In one example, the conductive fibers can be made of modified fibers, for example, the modified fibers include protein functional groups, so that the beard can better simulate a human beard, and the influence of the difference between the beard and the beard on the device to be tested is reduced.

Therefore, in the embodiment of the disclosure, the beard length can be acquired through the signal conduction device, so that the working efficiency of the tested device can be conveniently acquired. The embodiment of the present disclosure further provides a detection method, referring to fig. 13, including steps 131 to 133:

in step 131, the lengths of the individual hairs are acquired after the device under test has performed a shaving operation on the hairs on the test device.

In this embodiment, after the test device completes the preparation of the beard, the test device may display the prompt information for preprocessing the device under test. The content of the prompt information in step 71 can be referred to as the prompt information, and is not described herein again.

The signal transduction device 60 may then take the length of each individual beard hair. Referring to fig. 14, in step 141, the signal transmission device 60 may sequentially transmit the electrical detection signals to each beard, for example, the conductive fibers used by the beard include 2 wires including the first wire and the second wire, and the output end of the signal transmission device 60 transmits the electrical detection signals to the first wire, for example, the electrical detection signals may be high-level pulse signals with 3-5V, so as to obtain the transmission time. Considering that the device to be tested can sequentially shave off a part of the first conducting wire and the second conducting wire in the shaving test process, so that the first conducting wire and the second conducting wire are not in electrical connection, a layer of colloid containing metal particles can be sprayed or brushed in a predicted area after the shaving test is finished, and the metal particles can respectively contact the first conductor and the second conductor to form connection.

It should be noted that, considering that the diameter of the metal particles is equal to or slightly larger than the distance between the first conductor and the second conductor (micron level), and the distance between two adjacent beards (millimeter level) is much larger than the distance between the first conductor and the second conductor (micron level), the metal particles do not short-circuit two adjacent beards. In practice, the adjustment device 50 may be lowered to pull the hairs extending out of the substrate back until the ends of the hairs are flush with the surface of the substrate (or slightly lower than several tens of microns), i.e. all hairs are in the same plane, and then a layer of gel containing metal particles is sprayed or brushed to attach the metal particles only to the ends of the hairs.

In step 142, the receiving end of the signal conducting apparatus 60 may receive the feedback signal of the electrical detection signal in each beard, and may obtain the receiving time. In step 143, signaling device 60 may calculate the length of each beard based on the reference time, the transmission time, and the reception time.

In one example, a predetermined reference time may be stored in the signal transduction device 60, and the reference time may be a time difference between the reception time and the transmission time obtained when the length of the beard is calculated last time. In the initial state, the reference time is the time difference between the corresponding receiving time and the sending time when the beard is in the preset length (not being shaved). The signal transduction device 60 may calculate a time difference between the reception time and the transmission time and obtain a ratio of the time difference to a reference time. Since the reference time corresponds to the reference length of the beard, the ratio and the reference length can be used to calculate the length of the beard.

In another example, the signal transmission device 60 may calculate a time difference between the receiving time and the transmitting time, and since the transmission speed of the electrical detection signal is the speed of light, calculating the product of the time difference and the speed of light may obtain the length of the beard.

In step 132, the area of the beard at each length level is determined based on the length. Step 132 can refer to the content of step 72, and will not be described herein.

In step 133, the operating efficiency of the device under test is determined based on the area under each length level. For step 133, reference may be made to the content of step 73, which is not described herein again.

Before the simulated shaving test, the individual hairs 40 are adjusted to the same height, i.e. the individual hairs extend the same length beyond the base layer 30. In this way, the device under test (e.g., an electric shaver) can shave a beard 40 with the blade perpendicular to the beard according to preset control parameters (described in detail below), resulting in the effect shown in fig. 2. Then, the laser detection device 70 may emit a scanning signal to the first area and acquire a feedback signal of the scanning signal; the length of each beard and/or the area occupied by the same length of the beard are obtained through the scanning process, which will be described in detail later, and will not be described herein.

Therefore, the first region is scanned through the laser detection device, the length and/or the area of the beard are/is obtained, and therefore the working efficiency of the tested equipment is conveniently obtained.

The embodiment of the present disclosure further provides a detection method, referring to fig. 16, including steps 161 to 163:

in step 161, a three-dimensional image of the beard is constructed after the device under test has performed a shaving operation on the beard on the test device.

In this embodiment, after the test device completes the preparation of the beard, the test device may display the prompt information for preprocessing the device under test. The content of the prompt information in the first embodiment can be referred to, and is not described herein again.

Then, the laser inspection apparatus 70 may acquire a three-dimensional pattern including:

in one example, referring to fig. 17, in step 171, the laser detection device 70 may emit a laser scanning signal to each detection point within the preset area, and obtain the sending time. The laser detection device 70 is disposed outside the structural frame 20. In step 172, the laser detection device 70 may receive the echo signal of each laser scanning signal to obtain the receiving time. In step 173, the laser detection device 70 may calculate the distance between each detection point and the laser detection device according to the transmission time, the reception time, and the speed of light. For example, the laser detection device 70 may calculate a time difference between the receiving time and the sending time, and then calculate a product of the time difference and the speed of light, so as to obtain a distance between the laser detection device 70 and the detection point. In step 174, a three-dimensional pattern of the beard in the preset area is constructed according to the distance between the detection points. For example, the laser detection device 70 records the emission angle each time the laser scanning signal is emitted, and then a three-dimensional graph can be established by using the laser detection device as a reference point, and the three-dimensional graph effect is shown in fig. 10.

In another example, referring to fig. 18, in step 181, the laser detection device 70 may emit a laser scanning signal to each detection point within a preset area, and obtain the emission intensity. The laser detection device 70 is disposed outside the structural frame 20. In step 182, the laser detection device 70 may receive the echo signal of each laser scanning signal to obtain the reception intensity. In step 183, the laser detection device 70 may calculate the distance between each detection point and the laser detection device according to the emission intensity and the reception intensity. For example, the laser detection device 70 may calculate the attenuation intensity according to the emission intensity and the reception intensity, and query the distance between the laser detection device 70 and the detection point according to the preset corresponding relationship between the attenuation intensity and the distance. In step 184, a three-dimensional pattern of the beard in the preset area is constructed according to the distance between the detection points. For example, if the laser detection device 70 records the emission angle every time the laser scanning signal is emitted, a three-dimensional graph can be created with the laser detection device as a reference point.

In yet another example, the laser detection device is disposed inside a structural frame of the test apparatus. Referring to fig. 19, in step 191, the adjusting device is controlled to adjust the height of each beard so that the ends of the beard adjacent to the base layer are in the same plane. In step 192, the laser detection device is controlled to emit laser scanning signals to the detection points in the area corresponding to the preset area in the structural frame, so as to obtain the sending time. In step 193, the laser detection device may receive the echo signal of each laser scanning signal to obtain the reception time. In step 194, the distance between each detection point and the laser detection device is calculated from the transmission time, the reception time, and the speed of light. In step 195, a three-dimensional pattern of the beard in the preset area may be constructed based on the distance of each detection point.

It should be noted that the distance obtained in step 194 is the same as the actual distance to be shaved, since the height of the hair is adjusted in step 191 such that the end of the hair extending out of the base layer changes from a different height to being in the same plane, or the end of the hair located in the frame changes from being in the same plane to a different height.

In step 162, the area of the beard at each length level is obtained according to the three-dimensional graph. Step 172 may refer to the content of step 72, and will not be described herein.

In step 163, the operating efficiency of the device under test is determined based on the area at each length level. Wherein, step 163 can refer to the content of step 73, which is not described herein again.

Wherein, the base layer can be made of silica gel. And a plurality of through holes are arranged on the silica gel, and each through hole is used for penetrating at least one beard. The laser detection device is arranged inside or outside the structural frame, and the scheme is described by taking the example that the laser detection device is arranged outside the structural frame.

Referring to fig. 20, the test apparatus includes a structural frame 10; at least one preset area 20 is arranged on the structural frame body 10, and each preset area 20 is covered with a base layer 30 and a beard 40 arranged on the base layer 30. Before the simulated shaving test, the individual hairs 40 are adjusted to the same height, i.e. the individual hairs extend the same length beyond the base layer 30. In this way, the device under test (e.g., an electric shaver) can shave a beard 40 with the blade perpendicular to the beard according to preset control parameters (described in detail below), resulting in the effect shown in fig. 2. The laser processing device 80 may then send feedback signals of the light detection and the light detection signals to the respective beard hairs in sequence, and the sending time and the receiving time may obtain the length of the respective beard hairs, which will be described in detail later and will not be described herein.

In one embodiment, the beard may be made of modified fibers, for example, the modified fibers may include protein functional groups, which may enable the beard to better simulate a human beard, and reduce the effect of the difference between the beard and the beard on the device under test. Meanwhile, an optical fiber is arranged in the beard, the diameter of the beard is 60-80 microns, and the diameter of the optical fiber is 2-5 microns, so that the transmitting end of the laser processing device is connected with the first end of each optical fiber and used for transmitting optical detection signals to the first end of each optical fiber; and the receiving end of the laser processing device is in contact with the second end of each optical fiber and is used for receiving the feedback signal of the optical detection signal.

Therefore, in the embodiment of the present disclosure, the laser processing device can emit the light detection signal to each beard and obtain the length of the beard, thereby conveniently obtaining the working efficiency of the device under test.

The embodiment of the present disclosure further provides a detection method, referring to fig. 21, including steps 211 to 213:

Then, the laser processing device 80 may acquire a three-dimensional pattern including:

in one example, referring to fig. 22, in step 221, the laser processing device 80 may sequentially transmit the light detection signal to each beard to obtain the transmission time. In step 222, the laser processing device 80 may receive the feedback signal of each photodetection signal to obtain the receiving time. In step 223, the laser processing device 80 may calculate the length of each beard based on the transmission time, the reception time, and the speed of light. For example, the laser processing device 80 may calculate the time difference between the receiving time and the transmitting time, and then calculate the product of the time difference and the speed of light to obtain the length of the beard.

In another example, the laser processing device 80 may sequentially emit the light detection signals to the respective beard hairs to obtain the emission intensity. Then, the laser detection device 70 may receive the feedback signal of each photodetection signal to obtain the reception intensity. The laser detection device 70 may then calculate the length of the beard based on the emission intensity and the reception intensity. For example, the laser processing device 80 may calculate the attenuation intensity according to the emission intensity and the reception intensity, and query the length according to the attenuation intensity according to the preset correspondence between the attenuation intensity and the length.
