Description

Technical Field

[0001] The present invention relates to the technical field of comprehensive life testing of electric toothbrushes, and more specifically, to a comprehensive life testing device for electric toothbrushes. Background Art

[0002] An electric toothbrush is an oral cleaning tool that drives the brush head through a motor core to achieve automatic toothbrushing. The vibration frequency of the electric toothbrush is higher, which can more effectively remove dental plaque and food residues, reduce the occurrence of oral diseases. Just put the brush head into the mouth, turn on the switch, and move the brush head according to the correct toothbrushing method, without the need to frequently change the brushing force and direction like a manual toothbrush. For people with poor hand flexibility, such as children, the elderly or people with disabilities in their hands, it is more convenient to use.

[0003] Chinese Patent Application No. CN202222186318.6 discloses a comprehensive life testing device for electric toothbrushes, including a bracket for supporting the electric toothbrush to be tested; a first power source; a first telescopic part, connected to the first power source and corresponding to the position of the switch of the electric toothbrush to be tested, so as to control the switch of the electric toothbrush to be tested through the first power source; a counterweight block for loading a counterweight on the electric toothbrush to be tested; a second power source; a second telescopic part, connected to the second power source and corresponding to the position of the counterweight block, so as to make the counterweight block apply or cancel the influence on the electric toothbrush to be tested under the drive of the second power source; a vibration detection module for detecting the amplitude and / or frequency of the electric toothbrush to be tested; a voltage acquisition module for detecting the voltage of the battery in the electric toothbrush to be tested.

[0004] In the above technical solution, this comprehensive life testing device for electric toothbrushes can automatically test the life of the electric toothbrush. The two parameters of the vibration frequency and amplitude of the electric toothbrush have a direct impact on the cleaning effect of the toothbrush. The traditional testing methods for the vibration frequency and amplitude of electric toothbrushes mainly rely on equipment such as high-speed cameras and laser vibrometers. The vibration head of the electric toothbrush usually performs circular vibration with a relatively fast frequency. When using a high-speed camera and a laser vibrometer to test the electric toothbrush, there is an error in the measured vibration frequency value, which affects the accuracy of the vibration frequency test of the electric toothbrush, and further affects the quality of the electric toothbrush after leaving the factory. Summary of the Invention

[0005] The purpose of the present invention is to provide a comprehensive life testing device for electric toothbrushes to solve the problems raised in the above background art:

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] An integrated service life test device for an electric toothbrush, comprising a device body. Inside the device body, there is a movable seat that can move vertically up and down. On the top surface of the movable seat, a support ring is fixedly installed correspondingly. A toothbrush body is placed on the surfaces of the two support rings. Above the toothbrush body, there are two pressing rings for fixing it. On one end surface of the toothbrush body, there is an output shaft that can vibrate. On one side of the output shaft, there is a test device for testing its vibration frequency. The test device includes an inner ring and an outer ring. A plurality of through holes are jointly formed on the surfaces of the inner ring and the outer ring. Inside any one of the through holes, a probe that contacts the output shaft is slidably connected. A first spring for resetting the movement of the probe is sleeved on the surface of the probe. A plurality of mounting seats are fixedly installed on the surface of the outer ring. On the surface of any one of the mounting seats, a pointer disk is fixedly installed. On the bottom surface of the pointer disk, there is a sliding contact that slides reciprocally. The sliding contact contacts one end of the probe. On one side of the inner ring, there is a fixed disk. On the inner side surface of the fixed disk, an angle sensor for monitoring the pointer disk is fixedly installed.

[0008] By adopting the above technical solution, when the output shaft vibrates, it will squeeze the probe. The probe moves towards the pointer disk direction and compresses the spring. The movement of the probe will squeeze the sliding contact. At this time, the pointer disk rotates the pointer according to the movement distance of the probe. The angle sensor monitors the rotation angle of the pointer of the pointer disk in real time and transmits the monitored data to the graph instrument in the form of an electrical signal, so that the vibration amplitude of the toothbrush body can be obtained. According to how many times one of the probes moves during this period, the vibration frequency of the toothbrush body can be calculated. Compared with the traditional high-speed camera and laser vibrometer for testing electric toothbrushes, this test device can amplify the vibration signal, reduce the vibration frequency value and amplitude error of the tested toothbrush body, improve the accuracy of testing the vibration frequency and amplitude of the electric toothbrush, and thus ensure the quality of the electric toothbrush after leaving the factory.

[0009] Preferably, the number of through holes is the same as the number of probes, the number of through holes is the same as the number of mounting seats, and the number of pointer disks and angle sensors is the same.

[0010] Preferably, a fixed rod is fixedly connected between the fixed disk and the inner ring, and a plurality of connecting frames are fixedly connected between the inner ring and the outer ring.

[0011] Preferably, a support platform is fixedly installed on the inner bottom surface of the device body. A sliding rod is slidably connected to the surface of the support platform. One end surface of the sliding rod is fixedly connected to the bottom surface of the movable seat. A second spring is sleeved on the surface of the sliding rod. One end of the second spring is fixedly connected to the bottom surface of the movable seat, and the other end of the second spring is fixedly connected to the surface of the support platform.

[0012] Preferably, two pairs of support plates are fixedly installed on the surface of the support table correspondingly. A rotating rod is rotatably connected between any pair of the support plates.

A clamping plate is fixedly installed on the inner side surface of one end of one of the rotating rods, and a clamping ring is fixedly installed on the surface of one end of the other rotating rod. A spring shaft is arranged on the surface of any one of the rotating rods, and the rotating rod is rotatably connected with the support plate through the spring shaft.

[0013] By adopting the above technical solution, when the lifting plate moves downward to drive the movable frame and the pressing ring to move, when the pressing ring contacts the surface of the toothbrush body, the support ring and the pressing ring interact to initially clamp the toothbrush body. The moving seat continues to move downward to drive the two slope rails to move and squeeze the rollers, so that the two rotating rods rotate, and the toothbrush body is clamped under the mutual movement of the clamping plate and the clamping ring, ensuring the stability of the toothbrush body during testing.

[0014] Preferably, a housing is fixedly installed on the top surface of the device body. Above the two pressing rings, there is a lifting plate that can move vertically up and down. Two movable frames are fixedly installed on the bottom surface of the lifting plate correspondingly. The two pressing rings are fixedly connected with the lifting plate through the two movable frames.

[0015] By adopting the above technical solution, the electric telescopic rod retracts to drive the lifting plate to move downward to drive the movable frame and the pressing ring to move, and the support ring and the pressing ring interact to initially clamp the toothbrush body.

[0016] Preferably, an electric telescopic rod is fixedly installed on the inner bottom surface of the device body. A connecting rod is fixedly installed between the telescopic end of the electric telescopic rod and the lifting plate.

[0017] Preferably, a controller and a graph instrument are respectively fixedly installed on the surface of the device body. The graph instrument is electrically connected with the controller through a wire. The electric telescopic rod is electrically connected with the controller through a wire. The graph instrument is electrically connected with an angle sensor through a wire.

[0018] Preferably, a bracket is fixedly installed on the side surface of the support table. Above the bracket, there is a moving plate that can move vertically up and down. A chute is formed on the surface of the moving plate. A slider that matches the chute is slidably connected inside the chute. An L-shaped plate is fixedly installed on the top surface of the slider. One end surface of the L-shaped plate is fixedly connected with a fixed disk. A lead screw is rotatably connected inside the chute, and the lead screw is threadedly connected with the slider.

[0019] By adopting the above technical solution, according to the distance that the toothbrush body moves downward, at this time, the controller controls the telescopic device to expand and contract, so that the moving plate moves to drive the testing device to move to correspond to the position of the output shaft. After the position adjustment of the testing device is completed, the turntable is manually rotated. At this time, the lead screw rotates forward to drive the slider to move in the chute towards the position of the output shaft. The movement of the slider drives the L-shaped plate to move, so that the testing device moves along with the L-shaped plate and sleeves on the surface of the output shaft, realizing the rapid alignment of the position of the testing device and the output shaft, and thus improving the testing efficiency of the toothbrush body.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1) When this electric toothbrush comprehensive life test device is in use, the vibration of the output shaft will squeeze the probe. The probe moves towards the pointer disk and compresses the spring. The movement of the probe will squeeze the sliding contact. At this time, the pointer disk rotates the pointer according to the movement distance of the probe. The angle sensor monitors the rotation angle of the pointer of the pointer disk in real time, and transmits the monitored data to the graphometer in the form of an electrical signal, so that the vibration amplitude of the toothbrush body can be obtained. According to how many times one of the probes moves during this period, the vibration frequency of the toothbrush body can be calculated. Compared with the traditional high-speed camera and laser vibrometer for testing electric toothbrushes, this testing device can amplify the vibration signal, reduce the vibration frequency value and amplitude error of the tested toothbrush body, improve the accuracy of testing the vibration frequency and amplitude of the electric toothbrush, and thus ensure the quality of the electric toothbrush after leaving the factory.

[0023] 2) When this electric toothbrush comprehensive life test device is in use, the lifting plate moves downward to drive the movable frame and the pressing ring to move. When the pressing ring contacts the surface of the toothbrush body, the support ring and the pressing ring interact to initially clamp the toothbrush body. The moving seat continues to move downward to drive the two ramp rails to move and squeeze the rollers, so that the two rotating rods rotate. The mutual movement of the clamping plate and the clamping ring clamps the toothbrush body, ensuring the stability of the toothbrush body during testing.

[0024] 3) When the comprehensive life test device of this electric toothbrush is in use, according to the distance that the toothbrush body moves downward, at this time, the controller controls the telescopic device to expand and contract, so that the moving plate moves and drives the test device to move to correspond to the position of the output shaft. After the position adjustment of the test device is completed, manually rotate the turntable. At this time, the lead screw rotates forward and drives the slider to move in the chute towards the position of the output shaft. The movement of the slider drives the L-shaped plate to move, so that the test device follows the L-shaped plate to move and sleeved on the surface of the output shaft, realizing the rapid alignment of the position of the test device and the output shaft, and then improving the test efficiency of the toothbrush body.

[0035] Example 1: Please refer to Figure 1 - Figure 9, an integrated life test device for an electric toothbrush, including a device body 1. The device body 1 is used to test the vibration frequency and amplitude of the toothbrush body 5. Inside the device body 1, there is a movable seat 2 that can move vertically up and down. On the top surface of the movable seat 2, a support ring 3 is fixedly installed correspondingly. Two pressing rings 4 are arranged alternately with the two support rings 3 to ensure the stability of the toothbrush body 5. The toothbrush body 5 is placed on the surfaces of the two support rings 3. Above the toothbrush body 5, there are two pressing rings 4 for fixing it. On one end surface of the toothbrush body 5, there is a vibrating output shaft 6. The output shaft 6 is a conventional output shaft 6 in the prior art. On one side of the output shaft 6, there is a test device 7 for testing its vibration frequency. The test device 7 can amplify the vibration signal, reduce the vibration frequency value and amplitude error of the tested toothbrush body 5, and improve the accuracy of testing the vibration frequency and amplitude of the electric toothbrush. The test device 7 includes an inner ring 701 and an outer ring 702. A number of through holes 703 are jointly opened on the surfaces of the inner ring 701 and the outer ring 702. Inside any one of the through holes 703, a probe 704 in contact with the output shaft 6 is slidably connected. A first spring 705 for resetting its movement is sleeved on the surface of the probe 704. A number of mounting seats 706 are fixedly installed on the surface of the outer ring 702. On the surface of any one of the mounting seats 706, a pointer disk 707 is fixedly installed. At the bottom surface of the pointer disk 707, there is a reciprocating sliding sliding contact 708. The movement installation of the sliding contact 708 at the bottom surface of the pointer disk 707 is prior art and will not be elaborated in detail here. The sliding contact 708 is in contact with one end of the probe 704. On one side of the inner ring 701, there is a fixed disk 710. On the inner side surface of the fixed disk 710, an angle sensor 711 for monitoring the pointer disk 707 is fixedly installed. The angle sensor 711 is a conventional angle sensor 711 in the prior art. When the output shaft 6 vibrates, it will squeeze the probe 704. The probe 704 moves towards the pointer disk 707 and compresses the spring. The movement of the probe 704 will squeeze the sliding contact 708. At this time, the pointer disk 707 rotates the pointer according to the movement distance of the probe 704. According to the angle sensor 711, the pointer rotation angle of the pointer disk 707 is monitored in real time, and the monitored data is transmitted to the graph instrument 25 in the form of an electrical signal, so that the vibration amplitude of the toothbrush body 5 can be obtained. According to how many times one of the probes 704 moves during this period, the vibration frequency of the toothbrush body 5 can be calculated. Compared with the traditional high-speed camera and laser vibrometer for testing electric toothbrushes, the test device 7 can amplify the vibration signal, reduce the vibration frequency value and amplitude error of the tested toothbrush body 5, improve the accuracy of testing the vibration frequency and amplitude of the electric toothbrush, and thus ensure the quality of the electric toothbrush after leaving the factory.

[0036] The number of the through holes 703 is the same as the number of the probes 704, the number of the through holes 703 is the same as the number of the mounting seats 706, and the number of the pointer disks 707 and the angle sensors 711 is the same.

[0037] A fixing rod 709 is fixedly connected between the fixed disk 710 and the inner ring 701, and a plurality of connecting frames 8 are fixedly connected between the inner ring 701 and the outer ring 702.

[0038] A support platform 9 is fixedly installed on the inner bottom surface of the device body 1. A sliding rod 10 is slidably connected to the surface of the support platform 9. One end surface of the sliding rod 10 is fixedly connected to the bottom surface of the moving seat 2. A second spring 11 is sleeved on the surface of the sliding rod 10. One end of the second spring 11 is fixedly connected to the bottom surface of the moving seat 2, and the other end of the second spring 11 is fixedly connected to the surface of the support platform 9. The second spring 11 is used to reset the sliding rod 10 and drive the moving seat 2 to move back to its original position.

[0039] Two pairs of support plates 12 are fixedly installed corresponding to the surface of the support platform 9. A rotating rod 13 is rotatably connected between any pair of support plates 12. Slope rails 14 are arranged on the corresponding side surfaces of the moving seat 2. A roller 15 in contact with the slope rail 14 is rotatably connected to one end of any rotating rod 13. A clamping plate 16 is fixedly installed on the inner side surface of one end of one of the rotating rods 13. A rubber pad is installed on the surface of the clamping plate 16. A clamping ring 17 is fixedly installed on the surface of one end of the other rotating rod 13. A spring shaft 18 is arranged on the surface of any rotating rod 13. The rotating rod 13 is rotatably connected to the support plate 12 through the spring shaft 18. By moving the lifting plate 20 downward, the movable frame 21 and the pressing ring 4 are driven to move. When the pressing ring 4 contacts the surface of the toothbrush body 5, the support ring 3 and the pressing ring 4 cooperate with each other to initially clamp the toothbrush body 5. The moving seat 2 continues to move downward, driving the two slope rails 14 to move and squeeze the rollers 15, causing the two rotating rods 13 to rotate. The clamping plate 16 and the clamping ring 17 move relative to each other to clamp the toothbrush body 5, ensuring the stability of the toothbrush body 5 during testing.

[0040] A housing 19 is fixedly installed on the top surface of the device body 1. The housing 19 is used to protect the internal parts of the device body 1. An elevating plate 20 that can move vertically up and down is arranged above the two pressing rings 4. Two movable frames 21 are fixedly installed corresponding to the bottom surface of the elevating plate 20. The two pressing rings 4 are fixedly connected to the elevating plate 20 through the two movable frames 21. When the electric telescopic rod 22 retracts, it drives the elevating plate 20 to move downward, driving the movable frame 21 and the pressing ring 4 to move. The support ring 3 and the pressing ring 4 cooperate with each other to initially clamp the toothbrush body 5.

[0041] An electric telescopic rod 22 is fixedly installed on the inner bottom surface of the device body 1. A connecting rod 23 is fixedly installed between the telescopic end of the electric telescopic rod 22 and the elevating plate 20. The electric telescopic rod 22 is a conventional electric control push rod in the prior art.

[0042] On the surface of the device body 1, a controller 24 and a spectrogram instrument 25 are respectively fixedly installed. The spectrogram instrument 25 is electrically connected to the controller 24 through a wire. The electric telescopic rod 22 is electrically connected to the controller 24 through a wire. The spectrogram instrument 25 is electrically connected to the angle sensor 711 through a wire. The controller 24 is a conventional programmable control device in the prior art, and the spectrogram instrument 25 is a conventional spectrogram instrument 25 in the prior art.

[0043] Usage steps of the present invention: When this comprehensive life test device for an electric toothbrush is in use, first place the toothbrush body 5 on the surfaces of the two support rings 3. Operate the controller 24 to control the electric telescopic rod 22 to retract, so that the lifting plate 20 moves downward, driving the movable frame 21 and the pressing ring 4 to move (the two pressing rings 4 are arranged alternately with the two support rings 3). When the pressing ring 4 contacts the surface of the toothbrush body 5, as the electric telescopic rod 22 continues to retract, the pressing ring 4, the toothbrush body 5, and the support ring 3 move downward together, driving the moving seat 2 to move downward. The movement of the moving seat 2 drives the slide rod 10 to move and squeeze the second spring 11. During the downward movement of the moving seat 2, the two ramp tracks 14 move and squeeze the rollers 15, causing the two rotating rods 13 to rotate. One of the rotating rods 13 rotates to drive the clamping plate 16 to move and contact the bottom surface of the toothbrush body 5, and the other rotating rod 13 rotates to drive the clamping ring 17 to move and contact the end of the toothbrush body 5. Under the interaction of the clamping plate 16 and the clamping ring 17, the toothbrush body 5 is clamped. At this time, then place the test device 7 on the surface of the output shaft 6 (it should be noted that the position where the test device 7 is sleeved is on the entire cylindrical surface of the output shaft 6). At this time, the ends of the multiple probes 704 contact the surface of the output shaft 6. At this time, zero the pointer dial 707, and turn on the toothbrush body 5 to work. At this time, the vibration of the output shaft 6 will squeeze the probe 704. The probe 704 moves in the direction of the pointer dial 707 and compresses the spring. The movement of the probe 704 will squeeze the sliding contact 708. At this time, the pointer dial 707 rotates the pointer following the movement distance of the probe 704. Then the angle sensor 711 monitors the pointer dial 707 in real time, and transmits the monitored data to the graph recorder 25 in the form of an electrical signal. Specify the test time of the toothbrush body 5. According to how many times one of the probes 704 moves during this period, the vibration frequency of the toothbrush body 5 can be calculated. According to the angle sensor 711 monitoring the rotation angle of the pointer of the pointer dial 707 in real time and transmitting the monitored data to the graph recorder 25 in the form of an electrical signal, the vibration amplitude of the toothbrush body 5 can be obtained. This solution is that the vibration of the output shaft 6 will squeeze the probe 704. The probe 704 moves in the direction of the pointer dial 707 and compresses the spring. The movement of the probe 704 will squeeze the sliding contact 708. At this time, the pointer dial 707 rotates the pointer following the movement distance of the probe 704. According to the angle sensor 711 monitoring the rotation angle of the pointer of the pointer dial 707 in real time and transmitting the monitored data to the graph recorder 25 in the form of an electrical signal, the vibration amplitude of the toothbrush body 5 can be obtained. According to how many times one of the probes 704 moves during this period, the vibration frequency of the toothbrush body 5 can be calculated. Compared with the traditional high-speed camera and laser vibrometer for testing electric toothbrushes, this test device 7 can amplify the vibration signal, reduce the vibration frequency value and amplitude error of the tested toothbrush body 5, improve the accuracy of the vibration frequency and amplitude test of the electric toothbrush, and thus ensure the quality of the electric toothbrush after leaving the factory;The lifting plate 20 moves downward, driving the movable frame 21 and the pressing ring 4. When the pressing ring 4 contacts the surface of the toothbrush body 5, the support ring 3 and the pressing ring 4 interact to initially clamp the toothbrush body 5. The moving seat 2 continues to move downward, driving the two ramp rails 14 to squeeze the rollers 15, causing the two rotating rods 13 to rotate. The mutual movement of the clamping plate 16 and the clamping ring 17 clamps the toothbrush body 5, ensuring the stability of the toothbrush body 5 during testing.;

Above the bracket 26, there is a movable plate 27 that can move vertically up and down. A chute 28 is formed on the surface of the movable plate 27. A slider 29 that matches it is slidably connected inside the chute 28. The top surface of the slider 29 is fixedly installed with an L-shaped plate 30. One end surface of the L-shaped plate 30 is fixedly connected to the fixed disk 710. A lead screw 32 is rotatably connected inside the chute 28. The lead screw 32 is threadedly connected to the slider 29. According to the distance that the toothbrush body 5 moves downward, at this time, the controller 24 controls the telescopic device 33 to expand and contract, so that the movable plate 27 moves to drive the testing device 7 to move to correspond to the position of the output shaft 6. After the position of the testing device 7 is adjusted, the turntable 31 is manually rotated. At this time, the lead screw 32 rotates forward, driving the slider 29 to move in the chute 28 towards the position of the output shaft 6. The movement of the slider 29 drives the L-shaped plate 30 to move, so that the testing device 7 follows the L-shaped plate 30 to move and sleeved on the surface of the output shaft 6, realizing the rapid alignment of the position of the testing device 7 and the output shaft 6, and thus improving the testing efficiency of the toothbrush body 5.

[0045] One end of the lead screw 32 extends to one side of the movable plate 27. A turntable 31 is fixedly installed on the surface of the lead screw 32. A telescopic device 33 is fixedly installed on the surface of the bracket 26. The telescopic end of the telescopic device 33 is fixedly connected to the bottom surface of the movable plate 27. The telescopic device 33 is electrically connected to the controller 24 through a wire. The telescopic device 33 is a conventional electric control push rod in the prior art.

[0046] Usage steps of the present invention: When this electric toothbrush comprehensive life test device is in use, according to the distance that the toothbrush body 5 moves downward, at this time, the controller 24 controls the telescopic device 33 to expand and contract, so that the movable plate 27 moves to drive the testing device 7 to move to correspond to the position of the output shaft 6. After the position of the testing device 7 is adjusted, the turntable 31 is manually rotated. At this time, the lead screw 32 rotates forward, driving the slider 29 to move in the chute 28 towards the position of the output shaft 6. The movement of the slider 29 drives the L-shaped plate 30 to move, so that the testing device 7 follows the L-shaped plate 30 to move and sleeved on the surface of the output shaft 6, realizing the rapid alignment of the position of the testing device 7 and the output shaft 6, and thus improving the testing efficiency of the toothbrush body 5.
