Detailed Implementation Methods

[0044] To make the technical problems solved by the present invention, the technical solutions, and the beneficial effects clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0045] Please see Figures 1 to 7 The test method for the condition of a toothbrush includes the following steps:

[0046] S1: Measure the initial data of the toothbrush, including the following steps:

[0047] S101: Place toothbrush 1 horizontally on test platform 2, with the area above the neck of the toothbrush protruding from the test platform, wherein the bristles of the toothbrush face down;

[0048] S102: Using a measuring tool, obtain the vertical distance A from the lowest point of the toothbrush bristles to the horizontal plane;

[0049] S2: Simulate the use of a toothbrush, including the following steps.

[0050] S201: Use the fixing clamp 3 to clamp the handle of the toothbrush, wherein the bristles of the toothbrush face upward; S202: Use the head clamp 4 to clamp the head of the toothbrush, and suspend the weight 5 on the head clamp.

[0051] S203: The testing device 6 applies a pulling force to the weight so that the weight is in the initial position. At this time, the head of the toothbrush is not subjected to the pressure of the weight. The distance between the initial position and the head clamp is B, and the distance B is 6.5mm ± 0.5mm.

[0052] S204: The testing equipment removes the tension applied to the weight, and the weight falls from the initial position to the hanging position. After the head of the toothbrush is subjected to the pressure of the weight, the testing equipment applies a tension to the weight to make the weight return to the initial position.

[0053] S205: Determine the test cycle duration, wherein the time the weight remains in the suspension position is T1 / second;

[0054] The suspension time of the weight is T2 / second, which includes the time required for the weight to fall from the initial position to the suspension position, and the time required for it to return from the suspension position to the initial position.

[0055] The single test cycle is T = T1 / second + T2 / second, after the weight falls from the initial position to the suspension position and returns to the initial position.

[0056] S206: Calculate the total number of brushing times N = N1 × N2 × N3, where the brushing frequency is N1 per month / time, the number of brushing days per month is N2 per month, and the number of brushing times per day is N3.

[0057] S207: Calculate the number of test cycles T required for each simulated brushing session, S1, where S1 = N4 / T, and the duration of each brushing session is N4 seconds / session;

[0058] S208: Calculate the total number of test cycles T required to simulate the total number of brushing times, where S = N × S1.

[0059] S3: Measure the deformation data of the toothbrush. After repeating step S204 S times, proceed with the following steps.

[0060] S301: Set the settling time in X minutes;

[0061] S302: Place the toothbrush horizontally on the test platform and let it stand for X minutes, with the area above the neck of the toothbrush protruding from the test platform, wherein the bristles of the toothbrush face down;

[0062] S303: Use a measuring tool to obtain the vertical distance C from the lowest point of the toothbrush bristles to the horizontal plane;

[0063] S4: Calculate the deformation coefficient P=CA.

[0064] The toothbrush usage testing method of this invention includes the following steps: S1: measuring the initial data of the toothbrush; S2: simulating the toothbrush usage state; S3: measuring the deformation data of the toothbrush; S4: calculating the deformation coefficient P. A movable weight is suspended from the head of the toothbrush. This weight can move up and down according to a set pattern. When the weight moves downwards, it simulates the force on the toothbrush head during brushing; when the weight moves upwards, the toothbrush is in an unused state. This reciprocating motion simulates long-term brushing. This toothbrush usage testing method of the present invention can simulate different brushing pressures, providing a reference for the toothbrush deformation under normal brushing and excessive brushing force. Therefore, the deformation of the toothbrush indicates whether excessive brushing force has been applied, thus reminding the user to correct their brushing habits.

[0065] Furthermore, as a preferred embodiment of this solution and not a limitation, in step S202, in step S101, the handle of the toothbrush is located on the test platform, wherein, in the direction from the end of the toothbrush to the head, the support point 11 on the toothbrush that last contacts the test platform to the end of the toothbrush constitutes the handle.

[0066] Furthermore, as a preferred embodiment of this solution and not a limitation, in step S202, the toothbrushes in steps S1 to S3 are all subjected to bristle removal treatment.

[0067] Furthermore, as a preferred embodiment of this solution and not a limitation, in step S202, the distance D between the weight suspension point and the fixed clamp holding the toothbrush handle is in the range of 60mm to 65mm.

[0068] Furthermore, as a preferred embodiment of this solution and not a limitation, in step S202, the clamping position of the head clamp on the head of the toothbrush is from the tip of the toothbrush to the furthest hair implantation hole from the tip of the toothbrush.

[0069] Furthermore, as a preferred embodiment of this solution and not a limitation, in step S202, the weight is suspended at a midpoint between the bristle implantation hole near the head of the toothbrush and the bristle implantation hole near the tail of the toothbrush.

[0070] In this embodiment, the distance D = 63.5 mm, the vertical distance A = 6.5 mm ± 0.5 mm, T1 = 10 s, T2 = 2 s ± 1 s, T = 12 s ± 1 s, and the resting time X = 15 min ~ 20 min. Toothbrush simulated pressure test time: brush teeth twice a day, 2 minutes each time (the required cycle = 120 s / 12 s = 10 T).

[0071] This invention also discloses a toothbrush, including a toothbrush body. The deformation coefficient P of the toothbrush body is determined using a toothbrush usage test method. In this test method, the combined weight of the head clamp and weights is 550g ± 5g, the distance B is 6.5mm ± 0.5mm, and the total number of test cycles T (S) is 1800. Five samples of the toothbrush of this invention and three existing toothbrushes were used to simulate normal toothbrush use for three months using the aforementioned toothbrush usage test method. Each month is calculated as 30 days. The test data is shown in the table below.

[0072] Test data table 1:

[0073]

[0074] Therefore, it can be seen that the deformation coefficient P of existing products is 0 or close to 0, meaning that existing toothbrushes show almost no deformation after testing, indicating that the toothbrush does not deform under stress, thus protecting the gums. However, data from samples 1-5 show that the deformation coefficient P of the toothbrush of the present invention, under simulated normal use, ranges from 2mm to 9mm. Therefore, if the deformation coefficient P of the toothbrush is between 2mm and 9mm after use, the user has good brushing habits, and the toothbrush has the effect of protecting the gums under stress.

[0075] According to Table 1, the deformation coefficient P ranges from 2mm to 9mm, and further, it is determined that the deformation coefficient P ranges from 6.0mm to 9.0mm. That is, for a toothbrush, including the toothbrush body, the deformation coefficient P of the toothbrush body, determined by a toothbrush usage test method, ranges from 6.0mm to 9.0mm. In this toothbrush usage test method, the total weight of the head clamp and weights is 550g ± 5g, the distance B is 6.5mm ± 0.5mm, and the total number of test cycles T is 1800.

[0076] According to Table 1, the deformation coefficient P ranges from 6.0 mm to 9.0 mm, and further, the deformation coefficient P is found to be 8.5 mm.

[0077] This invention also discloses a toothbrush, including a toothbrush body. The deformation coefficient P of the toothbrush body, determined by a toothbrush usage testing method, ranges from 2.0 mm to 10.0 mm. In this method, the combined weight of the head clamp and weights is 1100 g ± 5 g, the distance B is 6.5 mm ± 0.5 mm, and the total number of test cycles T (S) is 1800. Five samples of the toothbrush of this invention and three existing toothbrushes were tested using the aforementioned toothbrush usage testing method for a simulated three-month period, with each month consisting of 30 days, simulating normal toothbrush use. The test data are shown in the table below.

[0078] Test data table 2:

[0079]

[0080] Therefore, it can be seen that the deformation coefficient P of existing products is 0 or close to 0, meaning that existing toothbrushes show almost no deformation after testing, indicating that the toothbrush does not deform under stress, thus protecting the gums. However, data from samples 1 to 5 show that the deformation coefficient P of the toothbrush of the present invention, under simulated normal use, ranges from 2mm to 10mm. Therefore, if the deformation coefficient P of the toothbrush is between 2mm and 10mm after use, the user has good brushing habits, and the toothbrush has the effect of protecting the gums under stress.

[0081] Furthermore, as a preferred embodiment of this solution and not a limitation, the deformation coefficient P of the toothbrush body ranges from 2.0 mm to 6.0 mm. Through multiple tests, the deformation coefficient P of the toothbrush body is concentrated between 2.0 mm and 6.0 mm, which suggests that there may be errors in individual samples or the testing process. To reduce these errors, the concentrated range of deformation coefficient P, i.e., 2.0 mm to 6.0 mm, is adopted. When the deformation coefficient P of the toothbrush is between 2.0 mm and 6.0 mm, the user has good brushing habits, and the toothbrush has the effect of protecting the gums by deforming under force.

[0082] The present invention also discloses a toothbrush, including a toothbrush body. The deformation coefficient P of the toothbrush body is measured to be in the range of 1.0 mm to 9.0 mm by a toothbrush usage test method. In the toothbrush usage test method, the total weight of the head clamp and the weight is 550 g ± 5 g, the distance B is 6.5 mm ± 0.5 mm, and the total number of test cycles T is 1200.

[0083] Five samples of the toothbrush of this invention and three existing toothbrushes were taken and tested using the above-described toothbrush usage test method for a simulated two-month period, with each month consisting of 30 days, simulating normal toothbrush use. The test data are shown in the table below:

[0084] Test data table 3:

[0085]

[0086] Therefore, it can be seen that the deformation coefficient P of the existing product is 0, meaning that the existing toothbrush shows almost no deformation after testing, indicating that the toothbrush does not deform under stress, thus protecting the gums. However, data from samples 1 to 5 show that the deformation coefficient P of the toothbrush of the present invention, under simulated normal use, ranges from 1mm to 9mm. Therefore, if the deformation coefficient P of the toothbrush is between 1mm and 9mm after use, the user has good brushing habits, and the toothbrush has the effect of protecting the gums under stress.

[0087] This invention also discloses a testing device 6 for simulating the use of a toothbrush, including a control device 61, a head clamp 4 for holding the head of the toothbrush, and a traction rope 7. The head clamp includes a mounting frame 41 for mounting weights. The traction rope connects the mounting frame to the control device. The control device pulls up or releases the mounting frame through the traction rope so that the head clamp bears or releases the gravity from the mounting frame.

[0088] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a pulley 8, wherein the traction rope is led out from the control device, passes around the pulley, and is connected to the mounting frame.

[0089] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the control device includes a servo motor module, the output of which is used to connect to the traction rope to pull or release the traction rope.

[0090] A timing module, which is electrically connected to the servo motor module;

[0091] The positioning module is electrically connected to the servo motor module and the timing module.

[0092] Furthermore, as a preferred embodiment of this solution and not a limitation, the test device simulating toothbrush usage simulates toothbrush usage through the following steps:

[0093] P1: The servo motor module starts, pulling or releasing the traction rope until the positioning module detects that the weight is in the initial position;

[0094] P2: The positioning module simultaneously triggers the servo motor module and the timing module. The servo motor module stops pulling or releasing the traction rope to keep the weight in the initial position, wherein the distance between the initial position and the head clamp is B.

[0095] P3: The timing module is activated. After T0 seconds, the timing module triggers the servo motor module to release the traction rope so that the weight falls to the suspension position and the weight's gravity acts on the head clamp.

[0096] P4: When the positioning module detects that the weight is in the suspended position, it triggers the timing module to pull up the traction rope through the servo motor module after T1 seconds, until the positioning module detects that the weight is in the initial position;

[0097] P5: Repeat steps P2 to P4 S times.

[0098] Furthermore, as a preferred embodiment of this solution and not a limitation, the timing module records the time from when the positioning module detects that the weight is in the initial position to when the positioning module detects that the weight is in the suspended position as T3;

[0099] The timing module records the time from when the positioning module detects that the weight is in the suspended position to when the positioning module detects that the weight is in the initial position as T4.

[0100] The suspension time of the weight is T2 = T3 - T0 + T4 - T1 / second, where the suspension time includes the time required for the weight to fall from the initial position to the suspension position and the time required for it to return from the suspension position to the initial position. The time the weight stays in the suspension position is T1 / second.

[0101] The working principle of this embodiment is as follows:

[0102] The toothbrush usage testing method of this invention includes the following steps: S1: measuring the initial data of the toothbrush; S2: simulating the toothbrush usage state; S3: measuring the deformation data of the toothbrush; S4: calculating the deformation coefficient P. A movable weight is suspended from the head of the toothbrush. This weight can move up and down according to a set pattern. When the weight moves downwards, it simulates the force on the toothbrush head during brushing; when the weight moves upwards, the toothbrush is in an unused state. This reciprocating motion simulates long-term brushing. This toothbrush usage testing method of the present invention can simulate different brushing pressures, providing a reference for the toothbrush deformation under normal brushing and excessive brushing force. Therefore, the deformation of the toothbrush indicates whether excessive brushing force has been applied, thus reminding the user to correct their brushing habits.
