Technical Field

[0001] The invention belongs to the technical field of amplitude testing of small household appliances, and more specifically, relates to an amplitude testing device. Background Art

[0002] At present, the oral care market is booming, and the sales of electric toothbrushes are increasing. Electric toothbrushes use the rapid rotation or vibration of the motor core to make the brush head produce high-frequency vibrations, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the oral cavity and have a massage effect on the gum tissue.

[0003] In principle, there are two types of electric toothbrushes: rotary and vibrating. The principle of rotary toothbrushes is simple, that is, the electric motor drives the circular brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. Rotary toothbrushes are noisy, clean the tooth surface very cleanly, and the cleaning of the gaps between teeth is relatively weak, but they cause great wear on the teeth and are not recommended for long-term use. Vibrating toothbrushes are more complicated and more expensive. There is an electrically driven vibration motor inside the vibrating toothbrush, which allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle, but the swing amplitude is very small.

[0004] As a mature product, there is currently a lack of equipment to test the amplitude of vibration-type electric toothbrushes, and there is a lack of testing on the amplitude of electric toothbrushes during the research and development stage. Summary of the invention

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also read Figures 1 to 3, the amplitude test device provided by the embodiment of the present invention is now described. The amplitude test device includes a base 1, a stage 2, a laser emitter 3, and a display film 4. The laser emitter 3, the display film 4 and the stage 2 are arranged on the base 1, and the stage 2 is used to carry the object to be tested. In this embodiment, the object to be tested is an electric toothbrush 19. The display film 4 is made of a translucent material, and the display film 4 is arranged above the stage 2. The display film 4 has a scale for convenient reading and judgment. A plane mirror 5 is arranged on the back of the brush head of the electric toothbrush 19, and the distance from the motor rotation shaft of the electric toothbrush 19 to the display film 4 is approximately equal to the distance from the plane mirror 5 to the display film 4. After the electric toothbrush 19 is started, the brush head swings left and right, and the laser spot is projected on the mirror surface, which is reflected by the mirror surface to the display film 4. During the swinging process of the brush head, a light ray appears on the display film 4, namely the line segment AB; the line segment swept by the bristles on the bristle placement table 14 is the line segment CD. Line segment AB and the boundary of the area swept by the laser form triangle ABE, line segment CD and the area swept by the bristles form triangle DCE, and triangle ABE is similar to triangle DCE, so the ratio of the length of line segment AB to the length of line segment CD is equal to the ratio of the height from point E to line segment AB to the height from point E to line segment CD. The length of the bristles is approximately equal to the height from point E to line segment CD, and the distance from the mirror to the display stand 6 is approximately equal to the height from point E to line segment AB. The swing distance of the bristles can be calculated based on the similarity ratio by measuring the length of the bristles, the length of the light, and the distance from the mirror to the translucent display stand 6, which is the amplitude.

[0028] Compared with the prior art, the amplitude test device provided by the present invention has a laser emitter 3 arranged on a base 1, a plane mirror 5 arranged on the object to be tested, and measures the amplitude of the object to be tested by the principle of laser reflection. The amplitude is tested by using the principle of laser reflection and the principle of similar triangles, and the principle is simple, easy to operate, and accurate in measurement. The problem that there is no device for testing the amplitude of an electric toothbrush 19 in the current research and development stage is solved.

[0029] Specifically, see Figure 1 and Figure 4 In this embodiment, the base 1 is provided with a support column 7 and a display stand 6, and the support column 7 is used to support the display stand 6, and the display sheet 4 is placed on the display stand 6. Two support columns 7 are provided on the base 1, and a display stand 6 is provided on each support column 7, and the display sheet 4 is clamped between the two display stands 6. Among them, clamping openings are opened on the opposite surfaces of the two stands, and the two ends of the display sheet 4 are respectively inserted into the clamping openings of the two stands.

[0030] See also Figure 1 , Figures 4 to 6, four legs 26 for supporting the loading platform 2 are arranged on the base 1, and a quick clamp 8 is arranged next to the loading platform 2. After the electric toothbrush 19 is placed on the loading platform 2, the quick clamp 8 is used to fix the electric toothbrush 19 on the loading platform 2. A groove for accommodating the electric toothbrush 19 is provided on the loading platform 2, and a buffer pad is arranged in the groove. The buffer pad can be a silicone pad 9. When the electric toothbrush 19 is placed, the electric toothbrush 19 contacts the silicone pad 9. The silicone pad 9 is used to separate the electric toothbrush 19 from the loading platform 2 to reduce the wear of the electric toothbrush 19 by the loading platform 2. The silicone pad 9 is connected to a long arm switch 10, one end of the long arm switch 10 is connected to the silicone pad 9, and the other end is connected to the laser emitter 3. After the electric toothbrush 19 is placed on the silicone pad 9, the pressure of the electric toothbrush 19 on the silicone pad 9 triggers the long arm switch 10, and the long arm switch 10 turns on the laser emitter 3, and the laser emitter 3 emits laser after being turned on. When the electric toothbrush 19 is removed from the silicone pad 9, the long arm switch 10 controls the laser emitter 3 to turn off, and the laser emitter 3 stops emitting laser. In addition, an adjustment slot 27 is respectively provided at the connection between the stage 2 and the four legs 26, and fasteners are provided on the legs 26 to fix and loosen the legs 26 and the stage 2, so that the stage 2 can be translated to adjust the position of the stage 2 on the base 1.

[0031] See also Figure 1 , Figures 4 to 6The base 1 is provided with a support rod 11, which is used to support the laser emitter 3. The base 1 is provided with a base 21, on which a support rod 11 is fixed, on which the laser emitter 3 is fixed, and on which a reading reflector 12 is also fixed, which is located above the laser emitter 3. The reading reflector 12 is connected to the support rod 11 through a first connecting block 22, which is sleeved on the support rod 11, and the reading reflector 12 is rotatably connected to the first connecting block 22, which is locked on the support rod 11 through a headless screw. The reading reflector 12 can feed back the reading on the display film 4 to the user. Since the light emitted by the laser emitter 3 is reflected vertically by the plane mirror 5 to the display film 4, the user needs to stand up to read the reading on the display film 4, which is not very convenient. The reading reflector 12 reflects the reading on the display film 4, so the user no longer needs to stand up to read the reading, which is more convenient. In addition, the reading reflector 12 is rotatably connected to the first connecting block 22, so the angle of the reading reflector 12 can also be adjusted, making it more convenient for the user to read the reading, which is more in line with the humanized design. The support rod 11 is also provided with a second connecting block 23, and the second connecting block 23 is also locked on the support rod 11 by a headless screw. A connecting rod 24 is provided on the second connecting block 23, and the above-mentioned laser emitter 3 is set at the end of the connecting rod 24. A connecting plate 25 is provided at the end of the connecting rod 24, and the laser emitter 3 is fixed on the connecting plate 25.

[0032] See also Figure 1 , Figure 2 , Figures 4 to 6 In this embodiment, a support seat 13 and a lever 12 are also provided on the base 1. The support seat 13 supports the lever 12, and the lever 12 is rotatably connected to the support seat 13. A placement table 14 is provided at one end of the lever 12, and an adjustment block 15 is provided at the other end. The placement table 14 is used to place the brush head of the electric toothbrush 19, and the adjustment block 15 is used to adjust the balance of the lever 12. A first slide groove and a second slide groove are provided on the lever 12. The placement table 14 is arranged in the first slide groove, and the adjustment block 15 is arranged in the second slide groove. The placement table 14 and the adjustment block 15 can slide in the first slide groove and the second slide groove respectively. The placement table 14 slides in the first slide groove to facilitate the position of the brush head of the electric toothbrush 19, and the adjustment block 15 slides in the second slide groove to adjust the balance of the lever 12. In addition, a lifting ring 18 is also provided on the adjustment block 15. The lifting ring 18 is used to hang an external weight block to adjust the balance of the lever 12. The weight block selected in this embodiment is a weight 20.

[0033] The following is the working process of the amplitude test device: first move the placement table 14 and the adjustment block 15 so that the stage 2 and the placement table 14 are in the same straight line and the lever 12 is balanced. The weight 20 can also be hung on the adjustable block 15 according to the required load, and the weight 20 of the same mass is placed on the placement table 14 to adjust the balance. A reflective lens is attached to the back of the brush head of the electric toothbrush 19, and the electric toothbrush 19 is placed in the silicone pad 9. The electric toothbrush 19 is clamped with a quick clamp 8. The electric toothbrush 19 triggers the long arm switch 10, and the long arm switch 10 turns on the power of the laser transmitter 3 to emit laser. Loosen the flange screw, adjust the position of the stage 2, place the bristles on the placement table 14, and then tighten the flange screw. Adjust the display stand 6 so that the distance from it to the reflective lens is a preset multiple of the bristle length (ten times in this embodiment) to facilitate accurate measurement of the amplified data. Loosen the two headless screws on the second connecting block 23, adjust the second connecting block 23 and the connecting rod 24 so that the laser beam emitted by the laser emitter 3 is reflected to the middle area of ​​the display sheet 4 through the reflective lens, and tighten the two headless screws on the first connecting block 22. Loosen the headless screws on the first connecting block 22, adjust the reading reflector 12, so that the operator can see the light spot through the reading reflector 12 when sitting down. Mark the size scale on the display sheet 4, start the electric toothbrush 19, swing the brush head, and the corresponding light will appear on the display sheet 4. Read the length of the light through the scale. Divide the length of the light by ten to get the amplitude measurement value of the electric toothbrush 19 and record it.

[0034] The present invention has the following beneficial effects:

[0035] The amplitude is amplified through optical principles to increase resolution, facilitate testing and reduce errors.

[0036] The reading can be carried out through the adjustable reading reflector 12, and the operator can sit or stand, with low labor intensity.

[0037] The laser head emits laser downwards and measures by reflection, which does not hurt the eyes.

[0038] The load of the electric toothbrush 19 is adjustable by replacing the weight 20, and the operation is convenient.

[0039] The display sheet 4 is provided with scales for easy reading and judgment.

[0040] When the toothbrush is placed in the silicone pad 9 through the long arm switch 10 , the laser emitter 3 works, thereby extending the service life of the laser emitter 3 .
