DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0030] In this embodiment, refer to Figure 1-9A toothpaste performance automatic brushing tester comprises a casing 1, a control panel 3 and a start switch 4 are arranged on the lower half of the front side of the casing 1, and a safety door 2 is arranged on the upper half of the front side of the casing 1.
[0031] A mounting platform 5 is disposed inside the housing 1 , and a bottom plate 6 is disposed on the mounting platform 5 .
[0032] From the attached Figure 4 It can be seen that a mounting frame 7 is provided on the rear half of the upper surface of the bottom plate 6, and the front side frame of the mounting frame 7 is inclined into a slope, on which a first-level slide 11 is slidably connected through a screw mechanism, as shown in the attached figure. Figure 5 or attached Figure 6 As shown, the screw mechanism includes a screw rod 8 arranged along the central axis of the front frame of the mounting frame 7, a nut pair 10 threadedly sleeved on the screw rod 8, and a rotating disk 9 arranged at the top of the screw rod 8 for controlling the rotation of the screw rod 8. The rotating disk 9 is manually controlled or can be made into a servo motor control, and its purpose is to control the primary slide 11 to slide up and down along the front frame of the mounting frame 7 and adjust its position.
[0033] As attached Figure 3 As shown, symmetrically arranged cams 15 and a secondary slide 17 are provided on both sides of the table surface of the primary slide 11, and the cam 15 on the same side is located above the secondary slide 17. A connecting arm 16 is rotatably installed on the wheel protrusion of the cam 15, and the movable end of the connecting arm 16 is connected to the top of the secondary slide 17 below.
[0034] Combined with Figure 6 The inner surface of the front frame of the mounting frame 7 is provided with two rotating wheels 13 which rotate coaxially with the corresponding cams 15, and two transmission motors 12 are respectively provided inside the mounting frame 7. The output end of the transmission motor 12 is provided with a transmission wheel, and the transmission wheel and the rotating wheel 13 on the same side are synchronously transmitted through a belt 14. The transmission motors 12 on both sides can respectively control the rotation of the rotating wheel 13 and the cam 15 on the same side, and further control the secondary slides 17 on both sides to slide along the table surface of the primary slide 11.
[0035] The transmission motors 12 on both sides can be designed to have the same power or different powers. The control of the transmission motor 12 can realize the lifting and sliding of the secondary slides 17 on both sides at the same frequency or different frequencies. The transmission motor 12 can also control the working time of the secondary slide 17. Under such a design, the drive of the transmission motor 12 can be used to simulate the duration and number of brushing. If different power motors are set on both sides, the test samples of toothpaste will increase at the same time.
[0036] The primary slide 11 is also provided with a row of lower mounting panels 23 along its lower edge, and the lower mounting panels 23 are provided with pressure detectors and tooth simulation components.
[0037] The pressure detector and tooth simulation components are described separately:
[0038] As attached Figure 8 As shown, the pressure detector includes a placement table 2501, a pressure sensor 2502 and a weight 2503, and the weight 2503 is embedded on the placement table 2501. The tooth simulation component includes a vertical row of simulated gums 26 and simulated teeth 27. The toothbrush 19 above can directly act on the surface of the simulated gums 26 and simulated teeth 27.
[0039] Specifically describe the structure provided on the secondary slide 17: Figure 7 And attached Figure 8 It can be seen that the secondary slide 17 is laterally provided with a plurality of upper mounting panels 24 arranged in sequence along its table surface, the upper mounting panels 24 are aligned with the lower mounting panels 23 one by one, and the plate surface of the upper mounting panel 24 is connected with a plurality of mounting sleeves 18 through fasteners, and each mounting sleeve 18 is respectively loaded with a toothbrush 19.
[0040] As attached Fig. 9 As shown, a toggle connecting rod 28 and an ejector 29 are provided inside the upper mounting panel 24. The toggle connecting rod 28 pushes the ejector 29 out of the upper mounting panel 24 and presses against the toothbrush 19. The toggle connecting rod 28 is pushed by an external micrometer and further pushes the ejector 29 outward. In this way, the degree to which the toothbrush 19 is pushed outward is the pressure exerted by the toothbrush 19 on the simulated gums 26 and the simulated teeth 27, which corresponds to the force exerted by different people when brushing their teeth. Here, the toggle connecting rod 28 and the ejector 29 are standard parts and are not described in detail.
[0041] The number of the pressure detectors and tooth simulation components is the same as the number of the mounting sleeves 18 and the ejector 29 provided on the secondary slide 17 and corresponds one to one. That is, each toothbrush 19 corresponds to one tooth simulation component.
[0042] In this embodiment, the force of brushing teeth is adjusted by first pushing the toggle connecting rod 28 to rotate through the micrometer and controlling the ejector 29 to push outward through the toggle connecting rod 28 to adjust the force of the toothbrush 19 acting on the tooth simulation component. After the adjustment of the brushing force of the toothbrush 19 is completed, the brushing test of the toothbrush 19 can be started.
[0043] Here, the pressure detector has two functions: one is to detect the force of brushing, which can be displayed in real time on the control panel 3; the other is to regularly detect the accuracy of the pressure sensor 2502. During the brushing test phase, the placement table 2501 and the weight 2503 are removed. During the non-brushing test phase, the staff can regularly put the placement table 2501 and the weight 2503 in, and the weight of the weight 2503 is used to indicate whether the pressure sensor 2502 is accurate.
[0044] Need to combine with Figure 3 A water tank 20 is provided on the front half of the upper plate of the bottom plate 6, and a frame plate 21 is provided on the top of the water tank 20. The frame plate 21 has a plurality of identical through holes along its length, and each through hole is respectively loaded with a water cup 22. The water cup 22 corresponds to the toothbrush 19 one by one, and the cup body of the water cup 22 is built into the water tank 20. The frame plate 21 maintains a vertical relationship with the secondary slide 17. It should be particularly noted that the tooth simulation component on the lower mounting panel 23 is also inserted into the corresponding water cup 22.
[0045] A tooth simulation component with a lower mounting panel 23 and a toothbrush 19 with an upper mounting panel 24 are respectively left in the same water cup 22. The toothpaste to be tested is applied to each toothbrush 19.
[0046] Before the test, the position of the primary slide 11 is adjusted by the lead screw mechanism, and then the brushing force of each toothbrush 19 is calibrated and determined by the ejector 29. Then, the transmission motor 12 starts to work, controls the rotation of the cam 15, and then controls the sliding of the secondary slide 17. At this time, the position of the primary slide 11 is fixed, and the toothbrush 19 on the secondary slide 17 slides up and down to brush the tooth simulation component. The actual brushing behavior is simulated by adjusting the brushing time, brushing number, and brushing force. After a period of testing time, the effect of the toothpaste can be measured through the brushing data performance of the tooth simulation component.
[0047] Finally, it should be noted that water is poured into the water tank 20, and a heater is installed in the water tank 20. The function of the heater is to heat the water temperature to simulate the oral temperature when brushing teeth, thereby further meeting the oral brushing environment requirements of people.
