At present, the comfort level of a rotary shaver product is judged mainly by means of human feeling, strong subjective consciousness exists, objective quantitative data of dermatology does not exist, the judging result is inaccurate, personal feeling is doped, the rotary shaver product cannot be used as a strong evaluation standard for describing the comfort level of the shaver, and the reliability is low.

Accordingly, the present disclosure provides a rotary test fixture by which a test can be performed for a hair removal device such as a shaver. Wherein the knife net of the shaver can be contacted with the skin of a human body or leather products of skin simulants, when the shaver is rotated by the rotation test gauge, the contact of the knife net with the skin or leather products can generate torque, the comfort level of the shaver is quantified by measuring the torque generated in the rotating process of the to-be-measured cutter mesh of the shaver and by acquiring the torque data, so that the shaving comfort level and smoothness can be objectively evaluated.

Specifically, fig. 1 is a simplified schematic diagram of a rotary test fixture 100, according to an exemplary embodiment. As shown in fig. 1, the rotary test fixture 100 may include a cutter mesh fixing assembly 1, a motor 2, and a torque sensor 3, the cutter mesh fixing assembly 1 may be used to fix a cutter mesh 200 to be tested, the cutter mesh 200 to be tested is a shaver mesh structure of a target shaver to be tested, an output shaft of the motor 2 is connected to the cutter mesh fixing assembly 1, thereby, when the motor 2 is operated, the cutter mesh fixing assembly 1 may be driven to rotate by the motor 2 to simulate a movement of the shaver mesh structure when a user shaves. Alternatively, the output shaft of the motor 2 may be directly connected to the cutter mesh attachment assembly 1 via a key slot arrangement or other connection arrangement (e.g., bolts, nuts, etc.). Alternatively, the output shaft of the motor 2 may be connected to the wire-fixing assembly 1 via a transmission element.

The torque sensor 3 may detect the torque of the wire-fixing assembly 1 when rotating, for example, the torque sensor 3 may be connected to the wire-fixing assembly 1 to detect the torque of the wire-fixing assembly 1 when rotating through the torque sensor 3. Alternatively, a torque sensor 3 may be attached to the surface of the blade net fixing member 1, and the torque sensor 3 may be rotated synchronously with the blade net fixing member 1; alternatively, the detecting element of the torque sensor 3 may be attached to the blade net fixing assembly 1 and rotate synchronously with the blade net fixing assembly 1, for example, the strain gauge of the torque sensor 3 is attached to the surface of the blade net fixing assembly 1 and rotates with the blade net fixing assembly 1, and the main body portion of the torque sensor 3 may be fixedly disposed. Of course, it is also possible that the torque sensor acquires the torque generated by the wire-fixing assembly when it rotates in a non-contact manner.

When the rotary test fixture 100 is in a ready state, as shown in fig. 2, the shaving scene can be simulated to contact the test mesh 200 assembled on the mesh fixing assembly 1 with the human skin 300, as shown in fig. 3, at this time, the human skin 300 is not deformed, when the rotary test fixture 100 is in a test state, as shown in fig. 4, the motor 2 is started to drive the mesh fixing assembly 1 and the test mesh 200 to rotate, and as the test mesh 200 contacts with the human skin 300, the human skin 300 is deformed, as shown in fig. 5, for example, the human skin 300 is exemplified by the human skin 300, before the test mesh rotates, as shown in fig. 3, the human skin 300 as a sample is circular, and after the rotation of the test mesh drives the human skin 300 to deform, the human skin 300 is elliptical, however, it should be understood that the deformation generated by the human skin 300 can also act on the mesh fixing assembly 1 to a certain extent, so that the mesh fixing assembly 1 generates a tiny deformation torque can be detected by the torque sensor 2, and the comfort of the test mesh 200 can be evaluated by the torque value of the deformation torque.

When the rotary test gauge 100 is not in a detection state, the cutter mesh fixing assembly 1 can be driven to rotate by the motor 2, and the rotation of the cutter mesh fixing assembly 1 can be detected by the torque sensor 2, so that the torque value of the cutter mesh fixing assembly 1 in no-load can be obtained, the calibration of the torque value obtained in the test state is facilitated, and especially when different types of cutter meshes 200 to be tested are detected, the torque values corresponding to the cutter meshes 200 to be tested can be compared based on the torque value of the cutter mesh fixing assembly 1 in no-load, and the accuracy of detection is improved.

In some embodiments, the torque sensor 3 may be connected with a related electronic device with a display in a wireless or wired manner, so that the electronic device may acquire and display related data detected by the torque sensor 3. In other embodiments, the rotary test fixture 100 may include a display connected to the torque sensor 3 to display the torque data detected by the torque sensor 3 via the display, so that a tester can intuitively understand the torque situation, and is beneficial to quickly judging an abnormal situation, and to terminate the test in time, so as to avoid damage to property or personnel.

In some embodiments, the cutter mesh fixing assembly 1 may be an unadjustable fixing structure, and the relative positional relationship between the cutter mesh fixing assembly 1 and the human skin 300 is mainly determined by a tester to manually move the cutter mesh fixing assembly 1, so that the acting force between the cutter mesh 200 to be tested and the human skin 300 is uncontrollable, which results in inaccurate acquired comfort data of different types of cutter mesh 200 to be tested under the same acting force. Therefore, in other embodiments, in order to simulate the practical application scenario, to detect the comfort of the cutter mesh 200 to be tested under different applied forces, as shown in fig. 6, the cutter mesh fixing assembly 1 may include a cutter mesh fixing seat 11, a connecting piece 12, and an elastic element 13, where the cutter mesh fixing seat 11 may be used to fix the cutter mesh 200 to be tested, one end of the elastic element 13 is connected to the cutter mesh fixing seat 11, the other end is connected to the connecting piece 12, and the cutter mesh fixing seat 11 is connected to the connecting piece 12, and the connecting piece 12 may be connected to an output shaft of the motor 2, such that the left end of the connecting piece 12 may be connected to the output shaft of the motor 2 in a key manner in fig. 6, so that when the output shaft end of the motor 2 rotates, the connecting piece 12, the cutter mesh fixing seat 11, and the elastic element 13 may all rotate along therewith.

When the rotary test fixture 100 is in a test ready state, the elastic element 13 is in a natural state, and the test wire 200 is located at the front end of the preset test position. When the rotary test gauge 100 is switched to the test state, the human skin 300 contacts with the test cutter net 200 and acts on the test cutter net 200 to enable the test cutter net 200 to retract to the preset test position, at the moment, the elastic element 13 is switched to the compression state, and the deformation of the elastic element 13 can generate acting force acting on the cutter net fixing seat 11, so that the acting force can act on the human skin 300 through the test cutter net 200, and the acting force is the reaction force of the user acting on the test cutter net 200, and the two acting forces are equal in magnitude and opposite in direction. Therefore, when the to-be-tested cutter mesh 200 is at the same preset test position, the comfort of different to-be-tested cutter meshes 200 under the action of the same acting force can be screened, for example, torque values of different to-be-tested cutter meshes 200 under the condition of different roughness can be compared, the influence of the roughness of the cutter mesh, the cutter mesh material or the cutter mesh related structure on the comfort of a user can be screened, so that a proper roughness value can be selected, for example, the shaving structure of the electric shaver such as the cutter mesh and the blade can be optimized according to the comfort of the to-be-tested cutter mesh 200 under the action of the same acting force.

In the description given here, the connection of the connecting member 12 to the output shaft of the motor 2 is taken as an example, in other embodiments, the cutter wire fixing seat 11 may be connected to the output shaft of the motor 2, and in other embodiments, both the cutter wire fixing seat 11 and the connecting member 12 may be connected to the output shaft of the motor 2, which is not limited in this disclosure. In the above embodiment, the elastic member 13 may include a spring, for example, the spring may include a cylindrical spring, or the elastic member 13 may include a flexible member, for example, a deformable flexible member such as a silicone member or a plastic member.

Optionally, the fixed connection between the cutter mesh fixing seat 11 and the connecting piece 12 may be also provided, the elastic element 13 may be detachably connected with the cutter mesh fixing seat 11 and the connecting piece 12 respectively, and the elastic element 13 may be replaced subsequently, so that the acting force provided by the elastic element 13 may be changed under the condition of the same compression amount, and then, multiple different acting forces may be applied. The comfort of the test mesh 200 is quantified.

Alternatively, the connecting piece 12 and the blade-net fixing seat 11 may be slidably connected in a deformation direction of the elastic element 13, and the connecting piece 12 and the blade-net fixing seat 11 may be synchronously rotated. Therefore, the compression of the elastic element 13 can be adapted by the relative sliding between the connecting piece 12 and the cutter mesh fixing seat 11, so as to generate a reaction force with the same direction as the user acting force, and further adjust the acting force acting on the human skin 300 through the cutter mesh 200 to be tested, and compared with the scheme of replacing the elastic element 13, the scheme is more convenient and quick, and of course, in the embodiment, the elastic element 13 can be detachably connected with the connecting piece 12 and the cutter mesh fixing seat 11, so that the quantity of the acting force to be detected can be increased, and more data samples can be acquired.

For example, in some embodiments, the elastic element 13 may be located between the mesh fixing seat 11 and the connecting piece 12, and the mesh fixing seat 11 and the connecting piece 12 may be connected to each other by other elements in a sliding manner, for example, the rotary test fixture 100 may further include a sliding rail fixedly connected to the connecting piece 12 and further slidingly connected to the mesh fixing seat 11, so as to adapt to the deformation of the elastic element 13 through the sliding connection between the mesh fixing seat 11 and the sliding rail.

As another example, as shown in fig. 6 and 7, the connecting piece 12 may include an open cavity 121 and a key slot 122 communicating with the open cavity 121, the elastic element 13 is disposed in the open cavity 121, and the elastic element 13 is connected with an inner wall of the open cavity 121, so that the size of the rotary test fixture 100 can be reduced relative to the scheme that the elastic element 13 is disposed between the connecting piece 12 and the blade net fixing seat 11. The cutter mesh fixing seat 11 may include a connection end 111, an assembly end 112 and a matching block 113, where the assembly end 112 is connected with the connection end 111, the connection end 111 is connected with the elastic element 13, the matching block 113 is disposed at the connection end 111, the connection end 111 may partially extend into the open cavity 121, and the matching block 113 and the key slot 122 are slidably connected in a deformation direction of the elastic element 13, so that the sliding connection between the connection piece 12 and the cutter mesh fixing seat 11 is realized through the matching of the matching block 113 and the key slot 122, and the connection piece 12 and the cutter mesh fixing seat 11 may synchronously rotate through the matching of the matching block 113 and the key slot 122. The maximum distance between the inner wall of the open cavity 121 and the elastic element 13 may be less than or equal to a set threshold, so that the elastic element 13 may be prevented from tilting by the deformation direction of the elastic element 13 of the inner wall of the open cavity 121, and the set threshold may be 1 cm, 2 cm, 5 cm, or the like, for example.

For example, the cross section of one end of the connecting end 111 disposed in the open cavity 121 may be non-circular, and the cross section of the portion of the open cavity 121 matching with the connecting end 111 is the same as the cross section of the connecting end 111, so that the sliding connection between the connecting piece 12 and the cutter mesh fixing seat 11 can be realized, and synchronous rotation between the two can be realized.

In some embodiments, in order to adapt to different forces applied to the test wire 200 by the user when the rotary test fixture 100 is switched to the test state, so as to test the comfort data of the test wire 200 under various forces, as shown in fig. 8, the rotary test fixture 100 may further include a support member 5 and a fixing member 6, the support member 5 is connected below the connecting member 12, the fixing member 6 may include an alignment hole 61, and the alignment hole 61 may accommodate the test wire 200 when the rotary test fixture 100 is in the test state, for example, the test wire 200 may be threaded through the alignment hole 61 and flush with the surface of the fixing member 6, where the test wire 200 is located at the preset test position in the foregoing embodiment, and then the human skin 300 may contact the test wire 200 by attaching to the surface of the fixing member 6. The fixing element 6 and the supporting element 5 are slidingly connected in the deformation direction of the elastic element 13, so that the connecting element 12 and the knife net fixing seat 11 can be driven to synchronously translate by the translation of the supporting element 5 relative to the fixing element 6.

When the rotary test fixture 100 is in the state to be tested, the cutter mesh fixing seat 11 partially penetrates the alignment hole 61 to be positioned at the outer side of the alignment hole 61, so that when the rotary test fixture is subsequently switched to the test state, the cutter mesh fixing seat 11 can slide towards the connecting piece 12 under the action of the human skin 300, further compress the elastic element 13, and apply a reaction force opposite to the user acting force through the elastic element 13. It will be appreciated that the alignment holes 61 may be sized so that at least the blade mesh holder can pass therethrough, based on which the positional relationship between the blade mesh holder 11 and the alignment holes 61 may be changed by relative sliding between the support 5 and the mount 6 prior to testing, thereby adjusting the length of the blade mesh holder 11 extending out of the alignment holes 61 to accommodate different user forces. Of course, the motor 2 may be fixedly provided to the support 5, in addition to the connection member 12.

The fixing member 6 may include a first side wall 62, a second side wall 63 and a third side wall 64, where the third side wall 64 connects the first side wall 62 and the second side wall 63, the alignment hole 61 is disposed on the third side wall 64, the supporting member 5 may be slidably connected with the first side wall 62 and the second side wall 63, and when the supporting member 5 slides relative to the fixing member 6, the supporting member 5 may move toward or away from the third side wall 64, and since the position of the alignment hole 61 is unchanged, by sliding the supporting member 5 relative to the first side wall 62 and the second side wall 63, it is possible to match different compression amounts of the elastic element 13 after the test is started.

Further, the first side wall 62 and the second side wall 63 may include through grooves 65, respectively, in order to facilitate moving the support 5, the support 5 may include a guide pillar 51, where the guide pillar 51 penetrates through the through grooves 65, and a portion of the guide pillar 51 that is matched with the first side wall 62 is located outside the first side wall 62, and a portion of the guide pillar 51 that is matched with the second side wall 63 is located outside the second side wall 63, and through a portion of the guide pillar 51 located outside the first side wall 62 and the second side wall 63, a position for implementing an acting force may be provided for a user, so that adjustment is facilitated. Alternatively, the end surface of the guide post 51 on the outer side may be recessed inward to form a recess groove, and the user may apply a force by acting on the recess groove to push the support 5 and the fixing member 6 to move relatively.

Alternatively, the fixing member 6 may further include an index mark provided to at least one of the first side wall 62 and the second side wall 63, the index mark may be used to identify the position of the support member 5, and the index mark is in a linear relationship with the compression amount of the elastic member 13. In other words, after the test is started, after the elastic element 13 is acted by the user, the elastic force provided by the elastic element 13 at this time, that is, the acting force acting on the skin 300 of the human body through the cutter mesh 200 to be tested, can be obtained through the position of the support 5 on the mark scale and the mapping relationship between the position obtained in advance or obtained through the test and the elastic force.

In the above embodiments, the connection end 111 and the assembly end 112 of the cutter mesh fixing seat 11 are detachably connected, the rotary test fixture 100 may be configured with a plurality of assembly ends 112 of different types, and the model of the assembly end 112 corresponds to the model of the cutter mesh 200 to be tested one by one, so that the comfort of a plurality of cutter meshes 200 to be tested can be quantified by the same rotary test fixture 100, and the structure of the cutter mesh 200 to be tested can be optimally designed based on the quantified parameters for the quantified parameters of the comfort of the same cutter mesh 200 to be tested. The assembly ends 112 of different types have a size difference, and the assembly ends 112 of the same size can be used for assembling the to-be-tested cutter mesh 200 with different factors such as materials, cutter spacing, roughness, contact cambered surface and the like, but the sizes are the same.

Based on the technical solution of the present disclosure, as shown in fig. 9, a rotation test method is further provided, where the rotation test method may be applied to a rotation test fixture 100, the rotation test fixture 100 may include a cutter mesh fixing assembly 1, a motor 2, and a torque sensor 3, the motor 2 and the torque sensor 3 may be respectively connected to the cutter mesh fixing assembly 1, and the cutter mesh fixing assembly 1 may be used to fix a cutter mesh to be tested. The rotary test fixture 100 may further include a controller by which the movement of the parts of the rotary test fixture 100 is controlled and by which the rotary test method may be performed. Specifically, the rotation test method may include the steps of:

In step 901, the control motor 2 drives the blade-net fixing assembly 1 to rotate.

In this embodiment, the motor 2 may be controlled to be switched to a start state, so that the blade-net fixing assembly 1 may be driven to rotate by the motor 2, and thus the blade net 200 to be tested provided to the blade-net fixing assembly 1 may be rotated synchronously. In particular, the motor 2 may be controlled to rotate clockwise or counterclockwise, in some embodiments, the access line of the motor 2 may be changed, and in other embodiments, the forward and reverse rotation control of the motor 2 may be implemented by inputting an electrical signal of the direct motor. For simulating a shaving scene, the rotational speed of the motor 2 may be less than or equal to 100r/min, e.g. may be in the range of 27r/min-33 r/min.

In step 902, a reference torque value generated when the cutter mesh fixing assembly rotates is detected when the cutter mesh to be measured is in contact with human skin or artificial skin.

In this embodiment, the torque sensor 3 is connected to the wire-fixing assembly 1, so that the torque value of the wire-fixing assembly 1 at the time of rotation can be detected, and thus the reference torque value can be obtained. Further, through the connection between the torque sensor 3 and the controller, the controller can acquire the reference torque value detected by the torque sensor 3. In some embodiments, when the motor 2 works for a preset period of time and the rotation of the cutter wire fixing assembly 1 is stable, the reference torque value detected by the torque sensor 3 can be obtained; in other embodiments, the reference torque value detected by the torque sensor 3 may be obtained when the motor 2 rotates by a preset number of revolutions, and may be specifically designed according to need, which is not limited by the present disclosure.

In step 903, a rotational torque value of the test wire 200 fixed to the wire fixing assembly 1 is obtained based on the reference torque value.

In some embodiments, a single reference torque value may be obtained and directly used as the rotational torque value of the cutter wire 200 to be tested; in still other embodiments, a plurality of reference torque values may be obtained, and the rotational torque value of the blade network 200 to be measured may be determined according to the plurality of reference torque values, for example, an average value or a median value of the plurality of reference torque values may be used as the rotational torque value of the blade network 200 to be measured; alternatively, the average value after the maximum value and the minimum value of the plurality of reference torque values may be removed as the rotation torque value, and may be specifically designed as needed, which is not limited by the present disclosure.

Based on this, the rotation test method can obtain the rotation torque value of the cutter mesh 200 to be tested when the cutter mesh fixing assembly 1 drives the cutter mesh 200 to be tested to rotate, and the comfort of the shaver is quantified through the obtained rotation torque value, so that the shaving comfort and smoothness can be objectively evaluated.

In some embodiments, as shown in fig. 10:

in step 101, when the cutter mesh to be tested is in contact with human skin or artificial skin, the motor 2 is controlled to drive the cutter mesh fixing assembly 1 to rotate.

In the embodiment, the motor 2 can be controlled to drive the cutter mesh fixing assembly 1 to rotate under the conditions of the same rotating speed and the same steering, and then the rotating torque value of the rotating speed and the rotating torque value of the cutter mesh to be measured can be obtained later; of course, in order to facilitate comparison between different knife grids to be tested, the comparison accuracy is improved, after corresponding rotation torque values are obtained under any rotation speed and corresponding steering conditions, the rotation speed and the steering can be sequentially switched by adopting a single variable method, a plurality of rotation torque values are obtained, and accordingly the reliability of rotation test results can be improved.

In step 102, the operation time period of the motor 2 is recorded.

In some embodiments, the recording of the working time is done by timing, in other embodiments, the working time can be recorded by recording the number of turns of the motor 2.

In step 103, it is determined whether the operation time period of the motor 2 is greater than or equal to a preset time period

In this embodiment, when the operation time period of the motor 2 is longer than or equal to the preset time period, the process proceeds to step 104, and when the operation time period is shorter than the preset time period, the process proceeds to step 102.

In step 104, when the operation time period of the motor 2 is greater than or equal to the preset time period, the reference torque value detected by the torque sensor 3 is acquired.

In this embodiment, the reference torque value detected by the torque sensor 3 may be periodically acquired when the operation time period of the motor 2 is longer than a preset time period. For example, the reference torque value may be obtained once every 2 seconds, or may be obtained once after the motor 2 rotates for a set number of turns, until the number of obtained reference torque values reaches a preset number, for example, 10 reference torque values may be obtained.

In step 105, it is determined whether the number of reference torque values reaches a preset number.

In this embodiment, when the number of reference torque values reaches the preset number, the process is switched to step 106, and when the number of reference torque values does not reach the preset number, the process is switched to step 104.

In step 106, an average of the plurality of reference torque values is calculated as the rotational torque value.

In this embodiment, an average value of a plurality of reference torque values may be calculated as the rotational torque value of the wire-net to be measured. In other embodiments, the spin torque value curve may also be derived from a plurality of reference torque values and time.

In practice, based on the difference of the bending directions of the cutter wire structures of the cutter wire to be tested, the rotation torque value of the cutter wire to be tested is related to the steering direction of the cutter wire to be tested, and besides, the rotation torque value of the cutter wire to be tested is also related to the type of the cutter wire to be tested, the rotating speed of the cutter wire to be tested and the normal force of the cutter wire to be tested during shaving. Therefore, a principle of single variable can be adopted, and the single variable is adjusted one by one in the rotation test process, so that the corresponding rotation torque value is obtained.

In some embodiments, the blade net fixing assembly 1 may include a blade net fixing seat 11, a connecting member 12, and an elastic member 13, wherein the blade net fixing seat 11 is used for fixing the blade net 200 to be tested, one end of the elastic member 13 is connected with the blade net fixing seat 11, the other end is connected with the connecting member 12, the connecting member 12 is connected with the blade net fixing seat 11, and at least one of the blade net fixing seat 11 and the connecting member 12 is connected with the motor 2, and the connecting member 12 is connected with the torque sensor 3.

in step 201, the elastic force of the elastic member 13 is obtained.

In this embodiment, the elastic force of the elastic member 13 may be obtained before the motor 2 drives the blade-net fixing member 1 to rotate; alternatively, in other embodiments, the elastic force of the elastic element 13 may be obtained during rotation of the blade-net fixing assembly 2 driven by the motor 2.

In step 202, a correspondence relationship between the elastic force and the rotational torque value is obtained.

Based on the elastic force obtained by step 201 and the rotational torque value obtained by fig. 9 or 11, the correspondence between the elastic force and the rotational torque value during a single test can be determined.

In step 203, the compression amount of the elastic element 13 is adjusted until a rotation torque value corresponding to each compression amount is obtained.

In this embodiment, after the test is completed in step 202, the compression amount of the elastic element 13 may be adjusted while keeping other conditions unchanged, and the elastic force corresponding to the adjusted compression amount and the corresponding rotation torque value thereof may be obtained again.

Wherein, in some embodiments, the elastic force can be manually measured by a user and then input into a controller of the rotary test fixture; in other embodiments, a measurement instruction may be issued, which may be used to instruct the measurement element to measure the elastic force of the elastic element 13; in further embodiments, the rotational test fixture comprises a support 5 and a fixture 6, the support 5 being connected below the connector 12; the fixing member 6 is slidably connected with the supporting member 5 in the deformation direction of the elastic member 13, so that a relative positional relationship between the supporting member 5 and the fixing member 6 can be obtained, and according to a preset mapping relationship and the relative positional relationship, an elastic force of the elastic member 13 can be obtained, for example, a scale can be provided on the supporting member 5 or the fixing member 6, and the elastic force of the elastic member 13 can be obtained through the scale and the preset mapping relationship.

The adjustment of the compression amount can be adjusted according to compression amount parameters defined in a preset compression amount set, so that a rotation torque value corresponding to each compression amount parameter of the preset compression amount set can be obtained.

Based on the method, under the condition that other conditions are unchanged, the normal force given by the hand of the user in the shaving scene can be simulated, and the rotating torque value of the cutter mesh to be tested under the action of different normal forces (the elastic force corresponding to the scheme) is compared, so that guidance on the operation of the user is facilitated, and the shaving comfort level is improved.

In some embodiments, as shown in fig. 12, the rotation test method may further include:

in step 301, the rotational speed of the motor 2 is acquired.

In step 302, a correspondence relationship between the rotational speed of the motor 2 and the rotational torque value is obtained.

In step 303, the rotational speed of the motor 2 is adjusted until a rotational torque value corresponding to each rotational speed is obtained.

In this embodiment, when the motor 2 rotates at the set rotational speed, a rotational torque value corresponding to the set rotational speed may be obtained, and then, the rotational speed of the motor 2 may be adjusted until a rotational torque value corresponding to each rotational speed parameter in the preset rotational speed set is obtained, while other conditions may be kept unchanged.

Based on the method, the shaving scene can be simulated under the condition that other conditions are unchanged, and the rotating torque value of the cutter mesh to be tested in the rotating speed mode is compared, so that guidance is provided for user operation, and the shaving comfort level is improved.

The rotation speed can be adjusted according to rotation speed parameters defined in a preset rotation speed set, so that a rotation torque value corresponding to each rotation speed parameter of the preset rotation speed set can be obtained.

In some embodiments, as shown in fig. 13, the rotation test method may further include:

in step 401, the steering of the motor 2 is acquired.

In this embodiment, in order to simulate the user's actual shaving scene, it is possible to turn the shaving scene counterclockwise or clockwise, so the motor 2 may be controlled to adjust the turning direction so as to know the rotational torque value when turning the shaving in different directions.

In step 403, a correspondence between the steering and rotational torque values of the motor 2 is acquired.

In step 401, the motor 2 is adjusted in steering until a corresponding rotational torque value for each steering is obtained.

In this embodiment, when this motor 2 rotates in the set steering, the rotational torque value corresponding to the set steering can be obtained, and then the steering of the motor 2 is adjusted until the rotational torque value corresponding to each steering parameter in the preset steering set is obtained, while other conditions can be kept unchanged.

Based on the method, the shaving scene can be simulated under the condition that other conditions are unchanged, and the rotating torque value of the cutter wire to be tested in the steering mode is compared, so that guidance is provided for user operation, and the shaving comfort level is improved.

The steering adjustment can be performed according to steering parameters defined in a preset steering set, so that a rotation torque value corresponding to each steering parameter of the preset steering set can be obtained.

Of course, in order to compare different knife nets to be tested, the knife net to be tested assembled on the knife net fixing seat 11 can be replaced, then the test is performed, and the comfortableness between different knife nets to be tested can be compared under the condition that other conditions are kept the same.

According to the foregoing embodiments, parameters for evaluating the comfort of the shaver may include motor speed, motor steering, elastic force, and type of blade net. Therefore, in the testing process, any parameter can be adjusted, and under the condition that other parameters are unchanged, the corresponding relation between any parameter and the rotation torque value is obtained until the corresponding relation between each parameter and the rotation torque value pole under the condition that other parameters are unchanged is obtained, and the rotation torque value table shown in fig. 14 can be obtained, wherein the knife network a to be tested, the knife network B to be tested and the knife network C to be tested can be the difference between the same knife network parameters, such as the difference of knife network diameters, or the difference of knife network roughness, or the difference of knife network materials. Based on the rotating torque value table, not only the comfort between different cutter nets to be tested can be corresponding, but also parameters affecting the comfort can be determined based on the same cutter net to be tested, and based on the parameters, the design can be improved, so that the market share of the shaver can be improved.

Further, according to the present inventors, when the rotational speed of the motor 2 is set, the steering direction, the elastic force, and the mesh diameter of the motor 2 are each used as a single variable, and a skin deformation index y (M) during shaving of the electric shaver can be obtained, where Z represents the rotational speed of the motor 2, F represents the elastic force (i.e., the shaving normal force) applied by the elastic element 13, D represents the mesh diameter, S represents the clockwise skin deformation torque, and N represents the counterclockwise skin deformation torque.
