Description

Technical Field

[0001] This invention relates to the field of toothbrush technology, specifically to an adaptive control tester for the aging performance of toothbrush materials under high and low temperature environments. Background Technology

[0002] As an indispensable oral cleaning tool in daily life, toothbrushes are used in a complex and diverse environment. They need to withstand long-term temperature changes in the oral cavity, saliva erosion, and temperature and humidity fluctuations in the external environment. This places stringent requirements on the aging resistance of toothbrush materials.

[0003] The clamping and fixing mechanisms of existing toothbrush material aging performance testing equipment under high and low temperature environments lack flexibility. Most of them use fixed clamps to hold the toothbrush at a single angle and position, which cannot simulate the multi-angle force state and positional changes of the toothbrush during actual use. This results in a deviation between the aging environment of the test sample and the actual use scenario, limiting the accuracy and reference value of the test results. Furthermore, some equipment can only simulate a single high or low temperature environment, and cannot accurately control the rate and temperature difference range of high and low temperature alternation cycles. In addition, the temperature field distribution is uneven, resulting in inconsistent aging degrees in different parts of the test sample.

[0004] Combining the above issues, we find that existing adaptive control testers for the aging performance of toothbrush materials under high and low temperatures are difficult to avoid simultaneously when in use. Even if they can solve these problems, they require external tools, thus failing to achieve the desired effect. Therefore, we propose an adaptive control tester for the aging performance of toothbrush materials under high and low temperatures. Summary of the Invention

The bottom surface of the moving plate 210 is fixedly connected to a first stepper motor 216. The output end of the first stepper motor 216 is fixedly connected to the bottom end of the rotating rod 218.

[0023] Four brake wheels 219 are fixedly connected to the bottom surface of the base plate 1. Two limiting plates 220 are fixedly connected to the outer surface of each set of brake wheels 219. The upper surface of each set of limiting plates 220 is fixedly connected to the bottom surface of the base plate 1. The position of the device can be easily moved and adjusted through the brake wheels 219. The limiting plates 220 can fix and limit the brake wheels 219, thus playing a fixed and limiting role. Four reinforcing plates 204 are fixedly connected to the outer surface of the support frame 206. The bottom surface of each set of reinforcing plates 204 is fixedly connected to the upper surface of the fixing plate 203. The position of the support frame 206 can be fixed through the reinforcing plates 204, thereby enhancing the stability of the device. Each set of reinforcing plates 204 has several identical fixing bolts 205 threadedly connected to its inner wall. The outer surface of each set of fixing bolts 205 is threadedly connected to the inner wall of the fixing plate 203. The fixing bolts 205 can fix and restrict the position of the reinforcing plate 204 to prevent it from shifting during use.

[0024] The specific implementation method of this embodiment is as follows: First, the toothbrush sample to be tested is evenly fixed on the placement rack 215 to ensure that the sample is installed firmly and to avoid falling off or shifting during the test. The clamping mechanism 2 is started through the external control terminal. The rotation parameters of the first stepper motor 216 are set according to the test requirements. After the first stepper motor 216 is powered on, it drives the rotating rod 218. Under the support of the first bearing 217, it drives the rotating plate 212 to rotate smoothly. Then, through the fixed rod 213, it drives the placement rack 215 and the toothbrush sample to rotate synchronously, realizing multi-angle simulation and restoring the toothbrush's usage state at different force angles during brushing. At the same time, according to the different usage positions of the toothbrush in the test scenario, the extension stroke and speed of the electric telescopic rod 208 are set. After the electric telescopic rod 208 is started, it pushes the sliding block 209 to make linear reciprocating motion along the slide groove 207. 09 drives the moving plate 210 to move synchronously, thereby adjusting the horizontal position of the placement rack 215 and the toothbrush sample in the main body 201 of the test chamber, simulating the state of the toothbrush in contact with the environment in different areas of the oral cavity. During the test, the fixing ring 214 reinforces the fixing rod 213 to prevent shaking during rotation. The protective box 211 provides protection for the first step motor 216 to avoid the influence of temperature and humidity changes in the test environment. The reinforcing plate 204 and the fixing bolt 205 ensure that the support frame 206 and the fixing plate 203 are firmly connected, ensuring the overall stability of the clamping mechanism 2. If it is necessary to adjust the placement position of the test instrument, the device can be moved by the brake wheel 219 at the bottom of the base plate 1. After reaching the designated position, the braking function of the brake wheel 219 is used to fix it. The limiting plate 220 further enhances the fixing effect of the brake wheel 219 to prevent the device from shifting during the test.

[0025] Example 2: Please refer to Figure 1 , Figures 5-9 The present invention provides a technical solution: an adaptive control tester for the aging performance of toothbrush materials under high and low temperature environments. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A temperature adjustment component 3 is provided above the base plate 1.

[0026] As a further definition of the temperature regulating component 3 of the present invention, the temperature regulating component 3 includes an exhaust duct 301 and a parameter adaptive control module 317. A refrigerator 302 is fixedly connected to the outer surface of the test chamber body 201. A circulating fan 303 is fixedly connected to the inner wall of the air inlet box 202. A temperature sensor 305, a humidity sensor 306, and two carbon fiber heating tubes 304 are fixedly connected to the inner wall of the test chamber body 201. A second stepper motor 315 and two support plates 308 are fixedly connected to the upper surface of the exhaust duct 301. A second shaft is fixedly connected to the inner wall of each support plate 308. A rotating rod 313 is fixedly connected to the output end of the second stepper motor 315, and the outer surface of the rotating rod 313 is fixedly connected to the inner ring of the second bearing 309. Several identical first bevel gears 311 are fixedly connected to the outer surface of the rotating rod 313. A second bevel gear 312 meshes with the outer surface of each first bevel gear 311. A guide plate 314 is fixedly connected to the inner ring of each second bevel gear 312. Several identical third bearings 310 are fixedly connected to the inner wall of the exhaust duct 301. The outer surface of each guide plate 314 is fixedly connected to the inner ring of the third bearing 310.

[0027] The outer surface of the second stepper motor 315 is fixedly connected to a dustproof housing 307. The bottom surface of the dustproof housing 307 is fixedly connected to the upper surface of the exhaust duct 301. The outer surface of the parameter adaptive control module 317 is fixedly connected to a control panel 316. The control panel 316 is electrically connected to the temperature sensor 305 and the humidity sensor 306 respectively through wires. The dustproof housing 307 can protect the second stepper motor 315 and prevent external dust and impurities from interfering with it.

[0028] The specific implementation of this embodiment is as follows: Before the test begins, the target temperature and humidity parameters, high and low temperature alternation cycle rate, and temperature difference range are input through the control panel 316. The parameter adaptive control module 317 receives and stores the relevant parameters, and starts the temperature adjustment component 3. According to the set temperature requirements, if a high temperature environment needs to be simulated, the carbon fiber heating tube 304 is energized to provide heat to the test chamber body 201. If a low temperature environment needs to be simulated, the refrigerator 302 is started to input cold energy into the test chamber body 201. If a high and low temperature alternation cycle is required, the parameter adaptive control module 317 automatically switches the working state of the carbon fiber heating tube 304 and the refrigerator 302 to accurately control the alternation rate and temperature difference. The temperature sensor 305 and the humidity sensor 306 collect the temperature and humidity data inside the test chamber body 201 in real time and transmit it to the control panel 316 through wires. The control panel 316 compares the actual data with the set parameters. If there is a deviation, the parameter adaptive control module 317 automatically adjusts the carbon fiber heating tube 304. The heating power of the heating element 304 and the cooling intensity of the refrigerator 302 achieve adaptive closed-loop control of temperature and humidity. The circulating fan 303 is started to accelerate the airflow circulation in the main body 201 of the test chamber, so that the temperature field is evenly distributed and the aging degree of different parts of the test sample is not inconsistent. At the same time, the second stepper motor 315 is started. Its speed parameters are set according to the airflow circulation requirements. The second stepper motor 315 drives the rotating rod 313 to rotate under the support of the second bearing 309. The rotating rod 313 drives the first bevel gear 311 on the surface to rotate synchronously. The first bevel gear 311 meshes and drives the second bevel gear 312 to rotate, which in turn drives the guide plate 314 to rotate under the support of the third bearing 310. The tilt angle of the guide plate 314 is adjusted to achieve precise control of the airflow speed and direction in the exhaust duct 301, optimize the airflow circulation effect in the test chamber. The dustproof shell 307 provides protection for the second stepper motor 315, preventing external dust from entering the motor and affecting its operating accuracy, and ensuring the long-term stable operation of the temperature regulation component 3.

[0029] Example 3: Please refer to Figure 1 , Figure 5 , Figures 10-12 The present invention provides a technical solution: an adaptive control tester for the aging performance of toothbrush materials under high and low temperature conditions. The present invention makes corresponding improvements to the technical problems mentioned in the background art. A sealing component 4 is provided on the outer side of the base plate 1.

[0030] As a further definition of the sealing component 4 of the present invention, the sealing component 4 includes a sealing baffle 401, a transparent observation window 409 fixedly connected to the inner wall of the sealing baffle 401, a groove 402 formed in the inner wall of the sealing baffle 401, a sealing air cushion 403 fixedly connected to the outer surface of the test chamber body 201, an air supply pipe 404 fixedly connected to the outer surface of the sealing air cushion 403, an air pump 406 fixedly connected to the end of the air supply pipe 404 away from the sealing air cushion 403, a filter box 405 fixedly connected to the output end of the air pump 406, a dustproof net 408 fixedly connected to the inner wall of the filter box 405, and the outer surface of the sealing air cushion 403 in contact with the inner wall of the groove 402.

[0031] A limiting frame 407 is fixedly connected to the outer surface of the air pump 406. The bottom surface of the limiting frame 407 is fixedly connected to the upper surface of the filter box 405. The limiting frame 407 can reinforce the air pump 406 and the filter box 405 to prevent them from shaking violently during operation.

[0032] The specific implementation method of this embodiment is as follows: After completing the installation of the toothbrush sample and setting of the test parameters, the sealing baffle 401 is closed, so that the sealing baffle 401 is in contact with the open end of the test chamber body 201. The air pump 406 is started, and the air pump 406 draws in outside air and delivers it to the filter box 405. The air is filtered by the dustproof net 408 in the filter box 405 to remove dust, particulate matter and other impurities from the air, preventing impurities from entering the sealing air pad 403 and affecting its sealing performance and service life. The filtered clean air is delivered to the sealing air pad 403 through the air supply pipe 404. After the sealing air pad 403 is inflated, it expands and fits tightly with the groove 402 on the inner wall of the sealing baffle 401 to form a double sealing structure, effectively blocking the inside of the test chamber body 201. External airflow exchange prevents leakage of temperature and humidity inside the chamber, ensuring the stability of test environment parameters. The limiting frame 407 fixes and reinforces the air pump 406 and the filter box 405, reducing the vibration generated when the air pump 406 is working and ensuring the stable operation of the sealing assembly 4. During the test, the staff can observe the status of the toothbrush sample inside the test chamber body 201 in real time through the transparent observation window 409 on the sealing baffle 401. The test progress can be monitored without opening the sealing baffle 401, avoiding damage to the test environment caused by opening the baffle. After the test, the air pump 406 is turned off, and the gas in the sealing air pad 403 is released through the air supply pipe 404. After the sealing air pad 403 contracts, the sealing baffle 401 can be opened to take out the test sample.

[0033] Specifically, this adaptive control tester for the aging performance of toothbrush materials under high and low temperatures operates / is used as follows: First, the toothbrush samples to be tested are evenly fixed on the placement rack 215 to ensure that the samples are securely installed and to prevent them from falling off or shifting during the test. The clamping mechanism 2 is started through the external control terminal. The rotation parameters of the first stepper motor 216 are set according to the test requirements. After the first stepper motor 216 is powered on, it drives the rotating rod 218. Under the support of the first bearing 217, it drives the rotating plate 212 to rotate smoothly. Then, through the fixed rod 213, it drives the placement rack 215 and the toothbrush samples to rotate synchronously, realizing multi-angle simulation and restoring the toothbrush's usage state at different force angles during brushing. At the same time, according to the different usage positions of the toothbrush in the test scenario, the extension stroke and speed of the electric telescopic rod 208 are set. After the electric telescopic rod 208 is started, it pushes the sliding block 209 to make linear reciprocating motion along the slide groove 207. The sliding block 209 drives the movement The plate 210 moves synchronously, thereby adjusting the horizontal position of the placement rack 215 and the toothbrush sample within the test chamber body 201, simulating the state of the toothbrush in contact with the environment in different areas of the oral cavity. During the test, the fixing ring 214 reinforces the fixing rod 213 to prevent shaking during rotation. The protective box 211 provides protection for the first stepper motor 216 to avoid the influence of temperature and humidity changes in the test environment. The reinforcing plate 204 and the fixing bolt 205 ensure that the support frame 206 and the fixing plate 203 are firmly connected, ensuring the overall stability of the clamping mechanism 2. If it is necessary to adjust the placement position of the test instrument, the device can be moved by the brake wheel 219 at the bottom of the base plate 1. After reaching the designated position, the braking function of the brake wheel 219 is used to fix it. The limiting plate 220 further enhances the fixing effect of the brake wheel 219 to prevent the device from shifting during the test. Before the experiment begins, the target temperature and humidity parameters, high and low temperature alternation rate, and temperature difference range are input through the control panel 316. The parameter adaptive control module 317 receives and stores the relevant parameters, and starts the temperature adjustment component 3. According to the set temperature requirements, if a high temperature environment needs to be simulated, the carbon fiber heating tube 304 is energized to provide heat to the test chamber body 201. If a low temperature environment needs to be simulated, the refrigerator 302 is started to input cooling energy into the test chamber body 201. If a high and low temperature alternation cycle is required, the parameter adaptive control module 317 automatically switches the working state of the carbon fiber heating tube 304 and the refrigerator 302 to precisely control the alternation rate and temperature difference. The temperature sensor 305 and humidity sensor 306 collect the temperature and humidity data inside the test chamber body 201 in real time and transmit it to the control panel 316 through wires. The control panel 316 compares the actual data with the set parameters. If there is a deviation, the parameter adaptive control module 317 automatically adjusts the carbon fiber heating tube 304. The heating power of 4 and the cooling intensity of the refrigerator 302 achieve adaptive closed-loop control of temperature and humidity. The circulating fan 303 is started to accelerate the airflow circulation in the main body 201 of the test chamber, so that the temperature field is evenly distributed and the aging degree of different parts of the test sample is not inconsistent. At the same time, the second stepper motor 315 is started. Its speed parameters are set according to the airflow circulation requirements. The second stepper motor 315 drives the rotating rod 313 to rotate under the support of the second bearing 309. The rotating rod 313 drives the first bevel gear 311 on the surface to rotate synchronously. The first bevel gear 311 meshes and drives the second bevel gear 312 to rotate, which in turn drives the guide plate 314 to rotate under the support of the third bearing 310. The tilt angle of the guide plate 314 is adjusted to achieve precise control of the airflow speed and direction in the exhaust duct 301, optimize the airflow circulation effect in the test chamber. The dustproof shell 307 provides protection for the second stepper motor 315, preventing external dust from entering the motor and affecting its operating accuracy, and ensuring the long-term stable operation of the temperature regulation component 3. Furthermore, after completing the installation of the toothbrush samples and setting the test parameters, the sealing baffle 401 is closed, ensuring it fits snugly against the open end of the test chamber body 201. The air pump 406 is then started, drawing in outside air and delivering it to the filter box 405. The air is filtered through the dustproof net 408 inside the filter box 405, removing dust, particulate matter, and other impurities to prevent them from entering the sealing air pad 403 and affecting its sealing performance and service life. The filtered clean air is then delivered to the sealing air pad 403 through the air supply pipe 404. After inflation, the sealing air pad 403 expands and fits tightly against the groove 402 on the inner wall of the sealing baffle 401, forming a double-sealed structure that effectively blocks the airflow between the inside and outside of the test chamber body 201. To prevent leakage of temperature and humidity inside the chamber and ensure the stability of test environment parameters, the limiting frame 407 fixes and reinforces the air pump 406 and the filter box 405, reduces the vibration generated by the air pump 406 during operation, and ensures the stable operation of the sealing assembly 4. During the test, the staff can observe the status of the toothbrush sample inside the test chamber body 201 in real time through the transparent observation window 409 on the sealing baffle 401 without opening the sealing baffle 401 to keep track of the test progress, avoiding damage to the test environment caused by opening the baffle. After the test, the air pump 406 is turned off, and the gas in the sealing air pad 403 is released through the air supply pipe 404. After the sealing air pad 403 contracts, the sealing baffle 401 can be opened to take out the test sample.
