Description
Technical Field
[0001] This utility model relates to the field of electric toothbrush testing technology, and in particular to an intelligent electric toothbrush testing rack. Background Technology
[0002] Smart electric toothbrushes are oral hygiene tools that integrate modern technology. Equipped with built-in smart chips and various sensors, they not only efficiently remove plaque and stains through high-frequency vibrations and multiple cleaning modes, but also sync brushing data to a mobile app via Bluetooth, providing users with personalized brushing suggestions and oral health tracking services. Smart electric toothbrush testing racks are professional devices specifically designed to test the performance of these toothbrushes. They simulate the human oral environment and brushing pressure and angle, accurately testing whether the electric toothbrush's vibration frequency meets standards, whether the brush head's oscillation amplitude is precise and stable, and other key indicators such as battery life and waterproofing, helping to produce reliable smart electric toothbrushes.
[0003] Smart electric toothbrush test fixtures typically include a model simulating the oral cavity, which mimics the shape of teeth, the texture of gums, and the space of the mouth. They also include clamps to hold the toothbrush stable during testing. A power system simulates brushing motions, including different brushing forces, angles, and frequencies. A sensor system precisely measures parameters such as the toothbrush's vibration frequency and brush head oscillation amplitude. The working principle involves fixing the smart electric toothbrush to the fixture, and the power system driving the toothbrush according to preset brushing patterns, such as different forces, frequencies, and angles. During this process, the sensor system monitors various performance indicators of the toothbrush in real time, such as vibration intensity and brush head movement trajectory, transmitting this data to a data acquisition system for recording and analysis to determine whether the electric toothbrush meets quality standards.
[0004] In existing technologies, electric toothbrushes often shake during testing, and some test racks cannot provide a stable fixing structure, making it difficult to guarantee the stability of electric toothbrushes during testing. This leads to inaccurate test data, causing deviations in key data collected by sensors and interfering with the correct assessment of product quality. Therefore, an intelligent electric toothbrush test rack is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an intelligent electric toothbrush test holder, which aims to improve the problem that some existing test holders cannot guarantee the stability of electric toothbrushes during the testing process.

As a further description of the above technical solution: The telescopic assembly includes a follower plate, the outer wall of which is fixedly connected to the outer walls of the two roughened rods. The outer wall of the follower plate is fixedly connected to two fixed cylinders. The inner wall of each fixed cylinder is fixedly connected to a spring. The other end of each spring is fixedly connected to a telescopic rod. The inner wall of the sliding table is slidably connected to the outer walls of the two telescopic rods. The other end of each telescopic rod is fixedly connected to a stop block. As a further description of the above technical solution: The testing mechanism includes a fixed plate, the outer wall of which is slidably connected to the outer walls of the two roughened rods, a compression cone is fixedly connected to the outer wall of the fixed plate, and a limit ring is fixedly connected to the top of the roughened rods; As a further description of the above technical solution: The top of the support base is provided with a sliding groove, and the outer wall of the roughened rod is slidably connected to the inside of the sliding groove; As a further description of the above technical solution: The outer wall of the gear is rotatably connected to the inside of the movable cavity, and the outer wall of the sliding plate is slidably connected to the inside of the movable cavity; As a further description of the above technical solution: The outer side of the gear meshes with the adjacent side of the two rack plates, and the bottom of the rack plates is slidably connected to the inside of the movable cavity; As a further description of the above technical solution: The outer wall of the telescopic rod is slidably connected to the inner wall of the fixed cylinder, and the bottom of the sliding platform is slidably connected to the top of the support base.
[0007] This utility model has the following beneficial effects: 1. In this utility model, the toothbrush shell is inserted into the middle of the support base, and the bottom of the electric toothbrush is initially fixed by the deformation of the mounting groove and the filling block. Then, the motor is turned on, and the motor drives the gear to rotate, thereby driving the rack plate to move linearly. This drives the sliding plate, the roughened rod, and the follower plate to move synchronously. Furthermore, due to the transmission action of the telescopic rod, the sliding table moves, thereby driving the column and the clamping block to move synchronously. This provides secondary fixation to the outside of the electric toothbrush, achieving multiple fixation of the electric toothbrush on the test frame. This ensures that the electric toothbrush is always in a stable state during the test, avoiding interference with the test data due to displacement or shaking, and ensuring the accuracy and reliability of the test results.
[0008] 2. In this utility model, the follower blocks continuously move towards each other. Due to the resistance of the sliding table, it slides relative to the follower rod, causing the follower plate and the sliding table to separate. Under the action of the abutment block, the telescopic column contracts and the spring is compressed. The roughened rod slides relative to the column, driving the fixed plate and the extrusion cone to perform an extrusion test on the electric toothbrush. This achieves horizontal positioning of the test part. At the same time, the fixed block can be moved so that it automatically stops due to friction after moving on the roughened rod, thereby achieving precise vertical positioning of the test part. This enables precise positioning of the structural strength test part and allows for the application of accurate test pressure to the key parts of the electric toothbrush, thereby obtaining more targeted and reliable test data and providing a strong basis for evaluating the true performance of the product.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figures 1 to 3 This utility model provides an embodiment of an intelligent electric toothbrush test holder, including a support base 1, which serves to stably support other components. A mounting groove 2 is formed in the middle of the support base 1, the shape of which matches the bottom shape of the electric toothbrush, allowing the electric toothbrush to be inserted into the test holder for initial fixation. A filling block 3 is fixedly connected to the top of the support base 1. The filling block 3 is made of a soft material, so that after the electric toothbrush is installed, the deformation of the filling block 3 fills the gap between the support base 1 and the electric toothbrush, thereby reinforcing the placement of the electric toothbrush. A toothbrush shell 4 is detachably connected to the top of the support base 1. A clamping mechanism is fixedly connected to the middle of the support base 1 to ensure that the electric toothbrush does not shift or shake during testing. A testing mechanism is fixedly connected to the top of the clamping mechanism to perform an overall structural strength test on the electric toothbrush.
[0013] The clamping mechanism includes a motor 5, whose outer wall is fixedly connected to the middle of the support base 1. The motor 5 is the power source for the entire clamping mechanism, providing a stable driving force. A transmission assembly is fixedly connected to the drive end of the motor 5, which transmits the power of the motor 5 to the subsequent structures. Two roughened rods 10 are fixedly connected to the top of the transmission assembly. The outer surface of the roughened rods 10 is roughened, allowing parts sliding on them to stop at their respective positions through friction when no vertical external force is applied. A sliding groove 11 is provided on the top of the support base 1, and the outer wall of the roughened rod 10 is slidably connected to the inside of the sliding groove 11. The sliding groove 11 provides a sliding path for the roughened rod 10 to move in the horizontal direction, thereby limiting the range of motion of the entire clamping mechanism and the testing mechanism, and preventing the clamping mechanism and the testing mechanism from shaking and causing poor test results. A telescopic assembly is fixedly connected to the outer wall of the roughened rod 10, which is used to link the testing mechanism and the clamping mechanism, thereby achieving the clamping and testing of the electric toothbrush while using a single driving source. A sliding platform 17 is slidably connected to the outer wall of the telescopic assembly, providing a motion base for the subsequent clamping structure. The bottom of the sliding platform 17 is slidably connected to the top of the support base 1, preventing the sliding platform 17 from derailing. Two columns 18 are fixedly connected to the top of the sliding platform 17, and clamping blocks 19 are fixedly connected to the top of the columns 18. The inner arc surface of the clamping blocks 19 has deformation capability, preventing the electric toothbrush from being damaged prematurely due to clamping before testing, thus affecting the test results. The movement of the sliding platform 17 drives the columns 18 to move, which in turn drives the two clamping blocks 19 to move towards each other to clamp the electric toothbrush.
[0014] The transmission assembly includes a gear 6, the top of which is fixedly connected to the drive end of the motor 5. The gear 6 transmits the power of the motor 5 to the subsequent structure. A movable cavity 9 is provided inside the support base 1, providing the necessary space for the gear 6 and the subsequent transmission assembly structure. The outer wall of the gear 6 is rotatably connected inside the movable cavity 9. Two rack plates 7 are slidably connected inside the support base 1, with their bottoms slidably connected inside the movable cavity 9. The rack plates 7 cooperate with the gear 6 to convert the rotational power of the motor 5 into linear motion power. The outer side of the gear 6 meshes with the adjacent side of the two rack plates 7, causing the two rack plates 7 to move towards each other through the rotation of the gear 6. A sliding plate 8 is fixedly connected to one end of each rack plate 7, with its outer wall slidably connected inside the movable cavity 9. The sliding plate 8 evenly transmits the motion of the rack plates 7 to the subsequent structure. The bottom of the roughened rod 10 is fixedly connected to the top of the sliding plate 8, so that the entire roughened rod 10 and the testing mechanism can move synchronously with the movement of the sliding plate 8.
[0015] Reference Figure 1 , Figure 2 , Figure 4The telescopic assembly includes a follower plate 12, the outer wall of which is fixedly connected to the outer walls of two roughened rods 10. The follower plate 12 can move with the movement of the roughened rods 10, providing basic displacement support for the subsequent movement of the telescopic assembly. Two fixed cylinders 13 are fixedly connected to the outer wall of the follower plate 12. The fixed cylinders 13 are used to fix the subsequent structure, ensuring a stable movement trajectory during telescopic movement. A spring 14 is fixedly connected to the inner wall of the fixed cylinder 13. The other end of the spring 14 is fixedly connected to a telescopic rod 15. The spring 14 provides the telescopic force for the telescopic rod 15, enabling it to adaptively adjust according to the actual size of the electric toothbrush. The outer wall of the telescopic rod 15 is slidably connected to the inner wall of the fixed cylinder 13, and the inner wall of the sliding platform 17 is slidably connected to the outer wall of the two telescopic rods 15. Through the sliding connection with the telescopic rods 15, the sliding platform 17 can be adjusted in position under the action of the telescopic rods 15, thereby achieving precise positioning of the electric toothbrush at different positions. The other end of the telescopic rod 15 is fixedly connected to a stop block 16. The stop block 16 is used to prevent the sliding platform 17 from derailing and to ensure the motion correlation between the sliding platform 17 and the roughened rod 10. After the sliding platform 17 moves synchronously with the roughened rod 10 for a period of time, the roughened rod 10 and the sliding platform 17 will move relative to each other due to the blocking effect of the support seat 1, so as to facilitate the precise positioning of the subsequent test mechanism operation.
[0016] The testing mechanism includes a fixed plate 20, the outer wall of which is slidably connected to the outer walls of two roughened rods 10. The fixed plate 20 can move up and down with the movement of the roughened rods 10, facilitating adjustment of the relative position of the testing mechanism and the electric toothbrush. A compression cone 21 is fixedly connected to the outer wall of the fixed plate 20. When structural strength testing of the electric toothbrush is required, the fixed plate 20 is driven to bring the compression cone 21 closer to the electric toothbrush by driving the roughened rods 10. The compression cone 21 can act on specific parts of the electric toothbrush with specific pressure and angle, simulating the external force experienced in actual use, thereby testing the structural strength of the electric toothbrush under this force condition. A limiting ring 22 is fixedly connected to the top of the roughened rods 10. The limiting ring 22 is used to limit the maximum upward movement of the fixed plate 20, preventing the fixed plate 20 from detaching from the roughened rods 10 during movement.
[0017] Working principle: When in use, the toothbrush shell 4 is inserted into the middle of the support base 1. The deformation of the mounting groove 2 and the filling block 3 initially fixes the bottom of the entire electric toothbrush. Then, the motor 5 is turned on. The operation of the motor 5 drives the gear 6 to rotate. When the gear 6 rotates, it drives the two rack plates 7 to move in opposite directions, thereby driving the two sliding plates 8 to move in opposite directions. This, through the transmission action of the rough surface rod 10, drives the follower plate 12 to move synchronously. When the follower plate 12 moves, it drives the sliding table 17 to move synchronously through the transmission action of the telescopic rod 15. This drives the column 18 and the clamping block 19 to move synchronously, thus providing secondary fixation to the outside of the electric toothbrush. The deformation capability of the inner arc surface of the clamping block 19 prevents the electric toothbrush from being damaged prematurely due to clamping before testing.
[0018] Once the fixing is complete, the motor 5 is continuously started. At this time, the follower blocks continue to move towards each other. Simultaneously, due to the resistance of the sliding table 17, it slides relative to the entire follower rod, thereby separating the movement of the follower plate 12 from the movement of the sliding table 17. At the same time, due to the action of the stop block 16, the entire telescopic column retracts, and the spring 14 is compressed so that it can automatically reset when not in use. This causes the roughened rod 10 to slide relative to the column 18, thereby driving the fixed plate 20 and the extrusion cone 21 to pass through the gap between the two columns 18 to perform an extrusion test on the electric toothbrush. At the same time, the fixed plate 20 can be moved and the friction provided by the roughened rod 10 can be used to achieve automatic suspension, thereby changing the extrusion position and achieving precise positioning of the test process.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
