Description

Technical Field

[0001] The present application relates to the technical field of electric toothbrushes, and in particular to a life testing method, a testing device, a storage medium, and a computer program product for an electric toothbrush. Background Art

[0002] An electric toothbrush typically consists of a handle and a detachable toothbrush head. Users frequently attach and detach the toothbrush head to the handle according to their needs. For example, some high-end electric toothbrushes support multiple types of toothbrush heads (such as cleaning, gum protection, and whitening), allowing users to choose toothbrush heads with different functions based on their personal needs, thus achieving personalized care. For another example, during daily use, users may need to detach the toothbrush head for a thorough cleaning, especially at the connection between the toothbrush head and the handle, where dirt or water stains easily accumulate.

[0003] This plugging and unplugging operation creates mechanical stress on the connection structure between the toothbrush head and handle (such as buckles, threads, or other fixing mechanisms). Long-term use may cause the connection structure to wear, loosen, or even fail, affecting the normal use of the product. Therefore, during the production process of electric toothbrushes, R&D personnel will test the durability of the connection structure between the toothbrush head and handle to verify that the electric toothbrush's lifespan meets the requirements.

[0004] However, traditional testing methods only focus on whether the number of plugging and unplugging times reaches a certain fixed threshold. Even if the number of plugging and unplugging times meets the standard, the connection force has dropped significantly. In actual use, users may encounter problems with the toothbrush head loosening or falling off before the number of plugging and unplugging times reaches the fixed threshold, thereby reducing the user experience. Summary of the Invention

[0005] The main purpose of this application is to provide a life test method, test device, storage medium and computer program product for an electric toothbrush, aiming to improve the traditional method of testing the life of the connection structure between the toothbrush head and the handle to improve the reliability of the test results.

[0006] To achieve the above objectives, the present application proposes a life test method for an electric toothbrush, which is applied to a testing device.

[0014] In one embodiment, when the overlap rate between the actual tension attenuation curve and the preset tension attenuation curve is less than a preset value, determining that the life of the electric toothbrush does not meet the standard includes:

[0015] Obtaining the slope of the actual tension attenuation curve on each horizontal axis, and determining the factor that causes the electric toothbrush life to fail to meet the standard according to the slope of the actual tension attenuation curve on each horizontal axis; wherein the horizontal axis of the actual tension attenuation curve is the number of plugging and unplugging times;

[0016] When the difference between the slope of one horizontal coordinate of the preset tension attenuation curve and the slope of the previous horizontal coordinate is greater than a first preset difference, determining that the factor causing the electric toothbrush to fail to meet the service life standard is a buckle breakage;

[0017] When the slope differences between adjacent horizontal coordinates of the preset tension attenuation curve are all less than a second preset difference, it is determined that the factor causing the electric toothbrush's service life to fail to meet the standard is material creep;

[0018] The first preset difference is greater than the second preset difference.

[0019] In one embodiment, the method further comprises:

[0020] Applying a preset pressure to the bristles of the toothbrush head and controlling the electric toothbrush to work continuously;

[0021] When the electric toothbrush continues to work for a predetermined time, the deformation amount of the bristles of the toothbrush head is obtained, and the service life of the electric toothbrush is determined according to the deformation amount;

[0022] When the deformation amount is not greater than the preset deformation amount, it is determined that the life of the electric toothbrush meets the standard; when the deformation amount is greater than the preset deformation amount, it is determined that the life of the electric toothbrush does not meet the standard.

[0023] In one embodiment, the electric toothbrush includes a battery, and the method further includes:

[0024] Perform multiple cycles of charge and discharge on the battery, and obtain the time consumed by the battery to complete each discharge, and determine whether the life of the electric toothbrush meets the standard based on the consumed time;

[0025] When the time consumed for each discharge of the battery is not less than the preset discharge time, it is determined that the life of the electric toothbrush meets the standard; when the time consumed for one discharge of the battery is less than the preset discharge time, it is determined that the life of the electric toothbrush does not meet the standard.

[0026] In one embodiment, the method further comprises:

[0027] The electric toothbrush is driven according to a preset periodic operation mode until the electric toothbrush stops working; wherein the preset periodic operation mode includes:

[0028] Controlling the electric toothbrush to work in the first half of the cycle and stop working in the second half of the cycle;

[0029] Obtaining the effective working time of the electric toothbrush in a preset cycle operation mode, and determining whether the life of the electric toothbrush has reached the standard based on the effective working time;

[0030] When the effective working time is not less than the preset working time, it is determined that the life of the electric toothbrush meets the standard; when the effective working time is less than the preset working time, it is determined that the life of the electric toothbrush does not meet the standard.

[0031] In one embodiment, the electric toothbrush further comprises a button, and the method further comprises:

[0033] When the electric toothbrush is in a powered-on state, it is determined that the life of the electric toothbrush meets the standard; when the electric toothbrush is in a powered-off state, it is determined that the life of the electric toothbrush does not meet the standard.

[0034] In addition, to achieve the above-mentioned purpose, the present application also proposes a testing device, which includes: a memory, a processor, and a computer program stored on the memory and runnable on the processor, the computer program being configured to implement the steps of the electric toothbrush life test method as described above; and a plug-in device, which is electrically connected to the processor and / or the memory.

[0035] In addition, to achieve the above-mentioned purpose, the present application also proposes a storage medium, which is a computer-readable storage medium.

[0037] The life test method of the electric toothbrush of the present application includes driving the plug-in and pull-out device to plug and unplug the handle and the toothbrush head multiple times; when the number of plug-in and pull-out times of the handle and the toothbrush head reaches a first preset number, obtaining the pulling force when the toothbrush head is separated from the handle, and determining whether the life of the electric toothbrush meets the standard based on the pulling force; when the pulling force is greater than or equal to the preset pulling force, determining that the life of the electric toothbrush meets the standard; when the pulling force is less than the preset pulling force, determining that the life of the electric toothbrush does not meet the standard. In this way, the present application simulates the aging process of the connection structure between the handle and the toothbrush head through high-frequency plug-in and pull-out. If the pulling force required for plugging and unplugging the handle and the toothbrush head after multiple plug-in and pull-out is less than the preset pulling force, it indicates that the connection structure may have been worn or loosened, that is, the life of the electric toothbrush does not meet the standard; on the contrary, if the pulling force required for plugging and unplugging the handle and the toothbrush head after multiple plug-in and pull-out is not less than the preset pulling force, it indicates that the connection structure is still stable, that is, the life of the electric toothbrush meets the standard. Compared with traditional testing methods, the life test method of the electric toothbrush in this application not only focuses on whether the number of plugging and unplugging times meets the standard, but also focuses on the degree of tension attenuation between the toothbrush head and the handle when the number of plugging and unplugging times meets the standard, so that this application can more accurately evaluate the actual life of the connection structure between the toothbrush head and the handle.

[0048] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0049] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0050] An electric toothbrush typically consists of a handle and a detachable toothbrush head. Users frequently attach and detach the toothbrush head to the handle according to their needs. For example, some high-end electric toothbrushes support multiple types of toothbrush heads (such as cleaning, gum protection, and whitening), allowing users to choose toothbrush heads with different functions based on their personal needs, thus achieving personalized care. For another example, during daily use, users may need to detach the toothbrush head for a thorough cleaning, especially at the connection between the toothbrush head and the handle, where dirt or water stains easily accumulate.

[0051] This plugging and unplugging operation creates mechanical stress on the connection structure between the toothbrush head and handle (such as buckles, threads, or other fixing mechanisms). Long-term use may cause the connection structure to wear, loosen, or even fail, affecting the normal use of the product. Therefore, during the production process of electric toothbrushes, R&D personnel will test the durability of the connection structure between the toothbrush head and handle to verify that the electric toothbrush's lifespan meets the requirements.

[0052] However, traditional testing methods only focus on whether the number of plugging and unplugging times reaches a certain fixed threshold. Even if the number of plugging and unplugging times meets the standard, the connection force has dropped significantly. In actual use, users may encounter problems with the toothbrush head loosening or falling off before the number of plugging and unplugging times reaches the fixed threshold, thereby reducing the user experience.

[0053] To this end, the present application proposes a life test method, test device, storage medium and computer program product for an electric toothbrush, aiming to improve the traditional method of testing the life of the connection structure between the toothbrush head and the handle to improve the reliability of the test results.

[0054] In one embodiment of the present application, reference Figure 1 The life test method of an electric toothbrush is applied to a test device, wherein the electric toothbrush includes a handle and a toothbrush head detachably connected to the handle. The test device includes a plug-in device for plugging and unplugging the handle and the toothbrush head. The life test method of the electric toothbrush includes:

[0055] Step S100: driving the plugging and unplugging device to repeatedly plug and unplug the handle and the toothbrush head, and recording the number of plugging and unplugging times;

[0056] It should be noted that after long-term plugging and unplugging of an electric toothbrush, the connection structure between the toothbrush head and handle (such as the buckle, thread, etc.) will gradually wear or deform due to mechanical stress, resulting in performance degradation. This application uses repeated plugging and unplugging operations to truly simulate the plugging and unplugging behavior of users during long-term use, thereby accelerating the exposure of the above potential problems in a relatively short period of time, and facilitating subsequent testing of the electric toothbrush's lifespan compliance.

[0057] The plugging and unplugging device includes a servo motor, a toothbrush head clamp and a handle clamp. The toothbrush head clamp and the handle clamp are used to clamp the toothbrush head and handle respectively. The toothbrush head clamp and the handle clamp are both arranged on the guide rail. The servo motor drives the screw to rotate, and the nut on the screw drives the toothbrush head clamp / handle clamp to move in a straight line along the guide rail, thereby realizing the plugging and unplugging of the toothbrush head and handle.

[0058] Step S200: When the number of times the handle and the toothbrush head are plugged in and out reaches a first preset number, obtaining a pulling force when the toothbrush head is separated from the handle, and determining whether the life of the electric toothbrush has reached a standard based on the pulling force;

[0059] It should be noted that the present application can use a force sensor to detect the pulling force when the handle and toothbrush head are separated. In one embodiment, the force sensor is installed between the toothbrush head fixture and the lead screw nut, so that the toothbrush head fixture is indirectly connected to the lead screw nut through the force sensor. When the servo motor drives the lead screw to rotate, the lead screw nut drives the toothbrush head fixture along the guide rail. When the toothbrush head fixture applies tension, the force sensor senses the separation force between the toothbrush head and handle and converts it into an electrical signal output. Based on the electrical signal, the pulling force separating the toothbrush head and handle can be determined.

[0060] It's important to note that the tensile force directly reflects the stability of the connection. By measuring the tensile force after reaching a first preset number of times, we can quantify the performance degradation of the connection after frequent plugging and unplugging. If the tensile force drops significantly, it indicates that the connection may be worn, deformed, or loose, indicating that the lifespan of the electric toothbrush is not meeting the required lifespan.

[0061] Among them, the first preset number of times is the expected service life of the electric toothbrush (such as 250 plugging and unplugging times corresponds to 2 years of normal use). Users can set it according to actual conditions and there is no restriction here.

[0062] In one embodiment, the present application can directly divide the lifespan compliance into two situations based on the comparison between the pulling force value and the preset pulling force:

[0063] Step S300: When the pulling force is greater than or equal to a preset pulling force, it is determined that the life of the electric toothbrush meets the standard; when the pulling force is less than the preset pulling force, it is determined that the life of the electric toothbrush does not meet the standard.

[0064] It should be noted that the preset pulling force value is the minimum performance standard (such as 5N to 15N) set according to product design requirements and actual user needs. After the handle and toothbrush head are plugged and unplugged a first preset number of times, if the pulling force is still greater than or equal to the preset pulling force, it means that the connection structure has been less worn or deformed even after multiple plugging and unplugging, that is, the service life of the electric toothbrush meets the standard. On the contrary, if the pulling force is lower than the preset pulling force, it indicates that there are design defects or material problems in the connection structure, which have caused it to be worn or deformed to a greater extent, even if the service life of the electric toothbrush does not meet the standard.

[0065] In another embodiment, the present application can also divide the pulling force into multiple levels to more carefully evaluate the lifespan of the electric toothbrush. For example, when the pulling force is greater than or equal to the preset pulling force + safety margin (e.g., 10N+2N=12N), the lifespan of the electric toothbrush is determined to be excellent, indicating that the connection structure is very reliable. When the preset pulling force is less than or equal to the preset pulling force + safety margin (e.g., 10N≤pulling value<12N), the lifespan of the electric toothbrush is determined to be good, indicating that the connection structure is relatively reliable. When the minimum pulling force is less than or equal to the preset pulling force (e.g., 8N≤pulling force<10N), the lifespan of the electric toothbrush is determined to be qualified, indicating that the connection structure meets the minimum requirements but still has room for improvement. When the pulling force is less than the minimum pulling force (e.g., pulling force<8N), the lifespan of the electric toothbrush is determined to be unqualified, indicating that the connection structure may be subject to significant wear or deformation.

[0066] Further, in order to speed up the life test progress of the electric toothbrush, in one embodiment, reference Figure 2 , after step S100, the following steps are included:

[0067] Step S110: obtaining the pulling force each time the handle and the toothbrush head are separated, until the number of plugging and unplugging the handle and the toothbrush head reaches a second preset number; wherein the first preset number is greater than the second preset number;

[0068] Step S120: establishing an actual tension attenuation curve according to the tension when the handle and the toothbrush head are separated multiple times, and comparing the actual tension attenuation curve with a preset tension attenuation curve;

[0069] It should be noted that the actual tension decay curve reflects the changing trend of the tension required to separate the handle and toothbrush head during multiple insertion and removal processes. The actual tension decay curve generally shows a trend of gradually decreasing tension as the number of insertions and removals increases. The preset tension decay curve is an ideal decay curve pre-set based on the tension decay curve of an electric toothbrush that has reached the service life standard. It is used to evaluate whether the actual tension decay curve meets expectations.

[0070] The units of the abscissas of the actual tension attenuation curve and the preset tension attenuation curve are the number of plugging and unplugging times, and the units of the ordinates are the tension values.

[0071] Step S130: when the overlap rate between the actual tension attenuation curve and the preset tension attenuation curve is greater than or equal to the preset overlap rate, driving the plugging and unplugging device to continue to repeatedly plug and unplug the handle and the toothbrush head;

[0072] When the overlap rate between the actual tension attenuation curve and the preset tension attenuation curve is less than the preset overlap rate, it is determined that the life of the electric toothbrush does not meet the standard.

[0073] It should be noted that the formula for calculating the overlap rate is the number of points where the actual force attenuation curve matches the preset force attenuation curve divided by the total number of test points, expressed as a percentage. The formula compares the deviation between the actual force value and the preset force value at each test point (number of times). If the deviation is within the allowable range (e.g., ±10%), the actual force attenuation curve is determined to match the preset force attenuation curve at the corresponding test point. Each time the actual force attenuation curve matches the preset force attenuation curve at a test point, the number of points where the actual force attenuation curve matches the preset force attenuation curve is incremented by one.

[0074] This application detects electric toothbrushes with excessively rapid performance degradation in advance by testing the performance degradation of the connection structure between the handle and the toothbrush head when the number of plug-in and unplugging times reaches a second preset number. When the overlap rate between the actual tension attenuation curve and the preset tension attenuation curve is less than the preset overlap rate (e.g., 95%), it indicates that the performance degradation of the connection structure between the handle and the toothbrush head of the electric toothbrush is too rapid, and there is no need to continue testing to the first preset number of times, thus saving testing time and resources. When the overlap rate between the actual tension attenuation curve and the preset tension attenuation curve is greater than or equal to the preset overlap rate, it indicates that the performance degradation of the connection structure is in line with expectations, and further testing is required to verify whether the service life meets the standard.

[0075] Furthermore, since the slope of the actual tension attenuation curve reflects the attenuation degree of the connection structure, the present application can determine the problem of the connection structure based on the slope of the actual tension attenuation curve when it is determined that the life of the electric toothbrush does not meet the standard. Figure 3 , after step S130, further comprising:

[0076] Step S131: Obtaining the slope of the actual tension attenuation curve on each horizontal axis, and determining the factor that causes the electric toothbrush to have a lifespan that does not meet the standard according to the slope of the actual tension attenuation curve on each horizontal axis; wherein the horizontal axis of the actual tension attenuation curve is the number of plugging and unplugging times;

[0077] Step S132: if the difference between the slope of one horizontal coordinate of the preset tension attenuation curve and the slope of the previous horizontal coordinate is greater than a first preset difference, determining that the factor causing the electric toothbrush to fail to meet the service life standard is a buckle breakage;

[0078] When the slope differences between adjacent horizontal coordinates of the preset tension attenuation curve are all less than a second preset difference, it is determined that the factor causing the electric toothbrush's service life to fail to meet the standard is material creep;

[0079] The first preset difference is greater than the second preset difference.

[0080] It should be noted that buckle breakage is a sudden failure mode, usually manifested as a sharp drop in the tensile force value in a short period of time. This application can quickly identify such problems by detecting the sudden change in the slope of the actual tensile force decay curve, that is, the slope difference exceeds the first preset difference (such as 0.5N / time). Material creep is a progressive failure mode, usually manifested as a slow drop in the tensile force value with a small change in the slope. This type of problem can be identified by detecting the smoothness of the slope of the actual tensile force decay curve, that is, the slope difference is less than the second preset difference (such as 0.1N / time).

[0081] In addition, the connection structure experiences significant surface wear during insertion and removal (such as buckle surface friction or thread wear), but the wear rate gradually decreases as the contact area increases. Therefore, the present application can also determine that the connection structure has significant surface wear when the initial slope of the actual tension decay curve is significantly greater than the later slope.

[0082] With this setting, compared with the traditional method that requires disassembling the product and performing complex physical or chemical analysis to determine the cause of failure, this application can quickly determine the cause of failure by simply analyzing the slope of the tensile attenuation curve, significantly shortening the analysis time and improving efficiency.

[0083] The life test method of the electric toothbrush of the present application includes driving the plug-in and pull-out device to plug and unplug the handle and the toothbrush head multiple times; when the number of plug-in and pull-out times of the handle and the toothbrush head reaches a first preset number, obtaining the pulling force when the toothbrush head is separated from the handle, and determining whether the life of the electric toothbrush meets the standard based on the pulling force; when the pulling force is greater than or equal to the preset pulling force, determining that the life of the electric toothbrush meets the standard; when the pulling force is less than the preset pulling force, determining that the life of the electric toothbrush does not meet the standard. In this way, the present application simulates the aging process of the connection structure between the handle and the toothbrush head through high-frequency plug-in and pull-out. If the pulling force required for plugging and unplugging the handle and the toothbrush head after multiple plug-in and pull-out is less than the preset pulling force, it indicates that the connection structure may have been worn or loosened, that is, the life of the electric toothbrush does not meet the standard; on the contrary, if the pulling force required for plugging and unplugging the handle and the toothbrush head after multiple plug-in and pull-out is not less than the preset pulling force, it indicates that the connection structure is still stable, that is, the life of the electric toothbrush meets the standard. Compared with traditional testing methods, the life test method of the electric toothbrush in this application not only focuses on whether the number of plugging and unplugging times meets the standard, but also focuses on the degree of tension attenuation between the toothbrush head and the handle when the number of plugging and unplugging times meets the standard, so that this application can more accurately evaluate the actual life of the connection structure between the toothbrush head and the handle.

[0084] In addition, the life of the electric toothbrush is also related to other aspects of the electric toothbrush, such as the life of the bristles of the toothbrush head, the life of the battery, the working time of the electric toothbrush or the life of the button, etc. Figure 4 , the method further comprises:

[0085] Step S410: applying a preset pressure to the bristles of the toothbrush head and controlling the electric toothbrush to continue working;

[0086] It should be noted that researchers can insert the toothbrush head into the handle, adjust the bristles of the toothbrush head to contact the surface, and then add a certain weight to the front of the handle to apply pressure to the bristles of the toothbrush head.

[0087] During long-term use, the bristles are repeatedly subjected to external forces (such as pressure and vibration), which gradually damages the internal structure of the material and causes fatigue. This application applies a preset pressure to the bristles of the toothbrush head and controls the electric toothbrush to operate continuously, which can realistically simulate the working scene of the user when brushing their teeth, thereby simulating the degree of deformation of the bristles after long-term use. The preset pressure is the average force applied by the user when brushing their teeth (such as 2N to 3N).

[0088] Step S420: When the electric toothbrush has been in operation for a predetermined time, the deformation amount of the bristles of the toothbrush head is obtained, and the life span of the electric toothbrush is determined based on the deformation amount.

[0089] It should be noted that the preset duration corresponds to the total operating time of the toothbrush head's cumulative service life (e.g., 6 hours), and the deformation directly reflects the wear, fatigue, or material performance degradation of the bristles during use. By measuring the deformation of the bristles after the preset operating time, this application can assess the bristles' resistance to fatigue, wear, and deformation during long-term use.

[0090] Step S430: When the deformation amount is not greater than a preset deformation amount, it is determined that the life of the electric toothbrush meets the standard; when the deformation amount is greater than the preset deformation amount, it is determined that the life of the electric toothbrush does not meet the standard.

[0091] It should be noted that the preset deformation amount is a reasonable range set according to design requirements and user needs (such as the length reduction does not exceed 1.2 mm).

[0092] Through the above settings, this application simulates the long-term use of an electric toothbrush by a user, replicates the degree of deformation of the bristles after long-term use, and determines whether the electric toothbrush has reached the required lifespan based on the degree of deformation of the bristles. For testers, the above testing scheme can detect potential problems at an early stage, avoiding large-scale production failures or after-sales repair costs caused by design defects.

[0093] In one embodiment of the present application, reference Figure 5 , the electric toothbrush includes a battery, and the method further includes:

[0094] Step S510: performing multiple charge and discharge cycles on the battery, and obtaining the time consumed by the battery to complete each discharge, and determining whether the life of the electric toothbrush has reached the standard based on the consumed time;

[0095] It should be noted that through multiple cycles of charge and discharge testing, the battery aging process of an electric toothbrush in actual use can be simulated. By obtaining the time consumed for each discharge, the attenuation of battery capacity over time can be intuitively reflected. If the battery performance gradually declines (manifested by a shortened discharge time), it means that the battery life may be approaching its limit.

[0096] Step S520: When the time consumed for each discharge of the battery is not less than the preset discharge time, it is determined that the life of the electric toothbrush meets the standard; when the time consumed for one discharge of the battery is less than the preset discharge time, it is determined that the life of the electric toothbrush does not meet the standard.

[0097] It should be noted that the preset discharge time is the minimum endurance standard (e.g., 60 minutes) set according to product design requirements. During multiple charge and discharge cycle tests, if the discharge time on a particular cycle is lower than the preset value, it indicates that the battery performance has significantly degraded (e.g., capacity decrease, internal resistance increase, etc.), meaning the battery life does not meet the standard. If the battery's discharge time on multiple occasions is not less than the preset discharge time, it indicates that the battery performance is relatively stable, meaning the battery life meets the standard.

[0098] With this setting, during the test process, if the tester finds that the discharge time of a certain time is lower than the preset discharge time, it can be judged in time that there is a potential problem with the battery, which helps the tester optimize product design, improve production processes or conduct quality control.

[0099] In one embodiment of the present application, reference Figure 6 , the method further comprises:

[0100] Step S610: driving the electric toothbrush according to a preset periodic operation mode until the electric toothbrush stops working; wherein the preset periodic operation mode includes:

[0101] Controlling the electric toothbrush to work in the first half of the cycle and stop working in the second half of the cycle;

[0102] It should be noted that users typically use electric toothbrushes intermittently rather than continuously. For example, a user might brush their teeth for two minutes at a time, then stop for a while before continuing. This application uses an "operating in the first half of the cycle, stopping in the second half" operating mode to more realistically simulate the user's actual usage habits, making the test results more realistic and avoiding deviations caused by test conditions not matching actual usage.

[0103] Step S620: obtaining the effective working time of the electric toothbrush in a preset cycle operation mode, and determining whether the life span of the electric toothbrush has reached the standard according to the effective working time;

[0104] It should be noted that the effective operating time is the total time the electric toothbrush can operate normally during a complete operating cycle (i.e., according to the "working in the first half of the cycle and stopping in the second half of the cycle" mode). During the test, the electric toothbrush runs repeatedly according to the preset cycle operating mode until the battery is exhausted or the performance degrades to the point where it no longer meets the requirements. The operating time of each operation is recorded and added together to calculate the effective operating time, which is used for subsequent life assessment.

[0105] Step S630: When the effective working time is not less than the preset working time, it is determined that the life of the electric toothbrush meets the standard; when the effective working time is less than the preset working time, it is determined that the life of the electric toothbrush does not meet the standard.

[0106] It should be noted that the preset working time is the minimum effective working time that the electric toothbrush needs to achieve within its normal service life. If the effective working time of the electric toothbrush is always not less than the preset working time, it means that its performance meets the design requirements; otherwise, it means that its performance can no longer meet normal usage needs.

[0107] Through the above settings, the present application can test the effective working time of an electric toothbrush by simulating a real scenario when a user uses an electric toothbrush, which helps to improve the reliability of the test results.

[0108] In one embodiment of the present application, reference Figure 7 , the electric toothbrush further includes a button, and the method further includes:

[0109] Step S710: continuously triggering the button, and when the number of times the button is triggered reaches a preset number of times, obtaining the working status of the electric toothbrush, and determining whether the life of the electric toothbrush has reached a standard according to the working status of the electric toothbrush;

[0110] Step S720: When the electric toothbrush is in the on state, determining that the life of the electric toothbrush meets the standard; when the electric toothbrush is in the off state, determining that the life of the electric toothbrush does not meet the standard.

[0111] This application simulates the total number of triggers during the standard life of an electric toothbrush (e.g., 10,000) by continuously triggering a button and setting a preset number of triggers. If the button becomes loose, fails, or experiences a circuit failure after multiple triggers due to potential design issues (e.g., mechanical wear or circuit failure), the electric toothbrush may not function properly. Therefore, this application determines that the electric toothbrush has met the standard lifespan when the button has been triggered the preset number of times and the electric toothbrush is still powered on; otherwise, it is considered unsatisfactory.
