[0002] Oral cleaning efficiency is affected by many factors, such as the type of toothpaste and toothbrush, brushing action, force, time, etc. In order to test the effect size of these factors on oral cleaning efficiency, that is, the degree of influence, for example, when testing the effect size of brushing action on oral cleaning efficiency, various factors such as brushing force are generally controlled to be as close to the real brushing environment as possible to ensure the accuracy and credibility of the conclusion. In related technologies, such as the tooth cleaning product performance evaluation system disclosed in patent CN112949537A, the clamping component drives the toothbrush downward and applies force to the force sensor through the end of the toothbrush away from the brush head. The detection result of the force sensor represents the force on the tooth model, but the clamping component has a direct supporting effect on the toothbrush, that is, it forms a fulcrum. Therefore, the force detection is indirect, and it is difficult to accurately reflect the actual force condition of the tooth model, which reduces the accuracy of the test results.

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] refer to Figure 1 and Figure 2The present application discloses an oral cleaning influencing factor analysis device 10, which can be used to conduct experimental research on various factors that affect oral cleaning efficiency, and then statistically analyze the effect size of these factors, that is, the degree of influence of these influencing factors on oral cleaning efficiency. For example, using the oral cleaning influencing factor analysis device 10 of the present application, different electric toothbrushes or ordinary toothbrushes can be replaced to study the effect size of the type of toothbrush on oral cleaning efficiency. For another example, different cleaning forces, speeds, times, movements, etc. can be replaced to study the effect size of these factors on oral cleaning efficiency. After obtaining the effect size of these factors on oral cleaning efficiency, users can choose the various consumer products required for oral cleaning more scientifically, and avoid spending too much on unimportant influencing factors. For manufacturers of oral cleaning equipment, they can design oral cleaning equipment more specifically based on the effect size of these factors, avoid investing too much cost in unimportant influencing factors, thereby optimizing the design and saving costs.

[0029] The oral hygiene influencing factor analysis device 10 includes a mounting seat 100 , a tooth brushing action simulation mechanism 200 and a tooth mold mounting mechanism 300 . Figure 1 、 Figure 2 The mounting base 100 shown is a simplified structure, roughly rectangular and plate-shaped, with a plurality of mounting holes 101 arranged in an array. The toothbrushing simulation mechanism 200 and the tooth mold mounting mechanism 300 are separately mounted on the mounting base 100, which provides support and position control. The mounting holes 101 and fasteners, such as bolts, facilitate adjustment of the mounting base 100, simplifying assembly and improving efficiency.

[0030] The tooth mold mounting mechanism 300 may include an adjustment assembly 310 and a sensor module 320. The sensor module 320 is connected to the output end of the adjustment assembly 310 and is used to detachably connect to the tooth mold 20. The adjustment assembly 310 is used to adjust the position of the sensor module 320 and the tooth mold 20 so that the external brushing action simulation mechanism 200 can contact and clean the surface of the tooth mold 20. The sensor module 320 is used to detect the pressure applied to the tooth mold 20 during the cleaning process.

[0031] Specifically, the adjustment assembly 310 includes a lifting module 311 and a translation module 313. The translation module 313 is connected to the output end of the lifting module 311, and the sensor module 320 is connected to the output end of the translation module 313. The lifting module 311 is used to move the tooth mold 20 in a first direction to adjust the height of the tooth mold 20 relative to the mounting base 100. The translation module 313 is used to move the tooth mold 20 in a second direction to adjust the position of the tooth mold 20 in the second direction parallel to the mounting base 100. In one embodiment, the first direction and the second direction are orthogonal to facilitate the adjustment of the position of the tooth mold 20. In other embodiments, the first direction and the second direction may form other angles.

[0032] Continue to refer Figure 1 and Figure 2 The lifting module 311 may include a driver 3111, a ball screw device 3113 connected to the output end of the driver 3111, and a slide 3115 that cooperates with the ball screw device 3113. The translation module 313 is detachably connected to the slide 3115. The driver 3111 may be a stepping motor, which can be combined with the ball screw device 3113 to perform relatively precise displacement control. When the output end of the driver 3111 drives the ball screw (not shown) inside the ball screw device 3113 to rotate, the slide 3115 that cooperates with the ball screw can move along the length direction of the ball screw, thereby driving the translation module 313 connected to the slide 3115 and the tooth mold 20 connected to the translation module 313 to translate in the first direction to adjust the relative position of the tooth mold 20 relative to the mounting base 100 or the tooth brushing action simulation mechanism 200. The structure and working principle of the translation module 313 can be similar to those of the lifting module 311. The translation module 313 can drive the tooth mold 20 to approach or move away from the brushing action simulation mechanism 200 along the second direction to facilitate the cleaning action on the surface of the tooth mold 20. No further details will be given here.

[0033] refer to Figure 3 and Figure 4 In some embodiments, the tooth mold 20 can be processed and formed using 3D scanning technology combined with 3D printing technology to obtain a model that is closer to the human physiological structure, thereby obtaining more accurate analysis results. Figure 3 The tooth model 20 includes a base 21 and multiple teeth 23 protruding from the base 21. The teeth 23 are arranged in a sequence that follows the curve of the gums. The junction between the base 21 and the teeth 23 resembles the surface of the gums, while the spaces between adjacent teeth 23 simulate the interdental spaces of the human body. This model structure, which closely resembles the actual physiological structure, facilitates accurate and reliable analysis results.

[0034] Furthermore, it can be considered that the tooth mold 20 has an occlusal direction, that is, the relative movement direction of the upper and lower teeth. Figure 4 In the illustrated embodiment, the occlusal direction can be considered perpendicular to the mounting base 100 or along the vertical direction, that is, the occlusal direction is parallel to the first direction. The central axis of the tooth portion 23 of the tooth mold 20 extends substantially along the vertical direction. This structural arrangement can more realistically simulate the scene of a user brushing their teeth, reduce the influence of other factors on the analysis results, and ensure the accuracy and reliability of the analysis results.

[0035] The toothbrushing simulation mechanism 200 is used to simulate a user's toothbrushing motion and may include a first movable assembly 210, a second movable assembly 220 connected to the output end of the first movable assembly 210, and a rotating assembly 230 connected to the output end of the second movable assembly 220. The first movable assembly 210 is connected to the mounting base 100, and the rotating assembly 230 is used to detachably mount a tooth cleaning member (not shown). The tooth cleaning member is not limited to an electric toothbrush and may also be a conventional toothbrush, such as a common hard straight-handled toothbrush. The first movable assembly 210 can be powered by a stepper motor, combined with a ball screw mechanism, to drive the second movable assembly 220 and the rotating assembly 230 to reciprocate in a second direction to simulate a user's horizontal brushing motion. The second movable assembly 220 can also be powered by a stepper motor, combined with a ball screw mechanism, to drive the rotating assembly 230 to move in a third direction to simulate a user applying pressure to the teeth through the tooth cleaning element. The rotating assembly 230 can also be powered by a stepper motor, combined with a chuck to facilitate the removal and installation of the tooth cleaning element, and to drive the tooth cleaning element to rotate to simulate the user's swinging brush head motion during brushing. The third direction is orthogonal to the first and second directions.

[0036] It is understood that in the embodiments of this application, parallelism and orthogonality should not be considered as strictly geometric relationships, but should take into account the existence of engineering errors. For example, when the angle between two lines is in the range of 85 degrees to 95 degrees, the two lines can be considered perpendicular in engineering. Of course, in other embodiments, any two of the first direction, the second direction, and the third direction may not be orthogonal, and the execution of the brushing action simulation mechanism 200 and the adjustment component 310 can be adaptively adjusted.

[0037] Continue to refer Figure 4 The sensor module 320 includes a first pressure sensor 321 connected to the output end of the translation module 313, and a second pressure sensor 323 connected to the first pressure sensor 321. The tooth model 20 is connected to the second pressure sensor 323. The first pressure sensor 321 is used to detect the pressure applied to the tooth model 20 in the third direction, and the second pressure sensor 323 is used to detect the pressure applied to the tooth model 20 in the first direction. The first pressure sensor 321 can detect the pressure applied to the tooth model 20 in the third direction, thereby simulating the pressure applied to the teeth by the user in the third direction. The second pressure sensor 323 can detect the pressure applied to the tooth model 20 in the first direction, thereby simulating the pressure applied to the teeth by the user in the occlusal direction, thereby preventing the accuracy and reliability of the analysis results from being affected by insufficient or excessive cleaning force.

[0038] In particular, the oral hygiene influencing factor analysis device 10 may include a controller (not shown) that combines the first pressure sensor 321 and the second pressure sensor 323 with the controller for closed-loop control. This allows for relatively precise control of the pressure applied to the tooth mold 20 in the first and third directions, stopping further pressure when the pressure is excessive, and increasing pressure when the pressure is insufficient. This ensures consistency in cleaning operations when changing different tooth molds 20 or different tooth cleaning components, or when changing the feed range, to avoid insufficient or excessive cleaning force that could affect the accuracy and reliability of the analysis results.

[0039] Of course, the control method of combining the first pressure sensor 321 and the second pressure sensor 323 with the controller can also be used to accurately control the movement of the lifting module 311 and the translation module 313 of the tooth mold mounting mechanism 300, so as to accurately adjust the position of the tooth mold 20 in real time during operation, and ensure the consistency of the cleaning operation when replacing different tooth molds 20 or different tooth cleaning parts, or changing the feed range, to avoid the cleaning force being too small or too large to affect the accuracy and credibility of the analysis results.

[0040] Furthermore, the tooth mold mounting mechanism 300 may include a connecting base 330 connected to the second pressure sensor 323, through which the tooth mold 20 is secured to the second pressure sensor 323. The connecting base 330 may include a base plate 331 and two baffles 333 extending from opposite edges of the base plate 331. The two baffles 333 and the base plate 331 together form a mounting groove 330a, within which a portion of the tooth mold 20 is accommodated. This structural arrangement utilizes the mounting groove 330a to securely position the tooth mold 20 on the connecting base 330, improving assembly convenience between the tooth mold 20 and the connecting base 330 and ensuring stable mounting of the tooth mold 20 on the second pressure sensor 323.

[0041] Continue to refer Figure 2 Combined with Figure 5 The tooth mold mounting mechanism 300 may include a connecting member 340 connected to the adjustment assembly 310. The connecting member 340 is generally L-shaped and has a first waist-shaped hole K1. A fastener such as a bolt can be passed through the first waist-shaped hole K1 and the mounting hole 101 of the mounting base 100 to removably secure the adjustment assembly 310 to the mounting base 100 via the fastener, thereby adjusting the relative position of the adjustment assembly 310 and the mounting base 100. For example, after adjusting the angle of the lifting module 311 relative to the tooth cleaning member and the distance relative to the brushing action simulation mechanism 200 in the horizontal plane, the fastener can be passed through the first waist-shaped hole K1 and inserted into the mounting hole 101 to reliably retain the adjustment assembly 310 on the mounting base 100.

[0042] Furthermore, the connecting member 340 may include an integrally formed first connecting portion 341 and a second connecting portion 343, wherein the first connecting portion 341 and the second connecting portion 343 are perpendicular to each other, the first connecting portion 341 having the aforementioned first waist-shaped hole K1, and the second connecting portion 343 having a second waist-shaped hole K2. The second waist-shaped hole K2 is used to pass a fastener through and adjust the relative position of the adjustment assembly 310 and the second connecting portion 343, thereby adjusting the position of the lifting module 311 relative to the mounting base 100, for example, adjusting the angle at which the lifting module 311 deviates from the vertical direction. A connecting hole (not shown) for fixing may be provided on the ball screw 3113 of the lifting module 311. After adjusting the relative position of the ball screw 3113 and the second connecting portion 343, the fastener may be passed through the second waist-shaped hole K2 and screwed into the connecting hole, so that the position of the ball screw 3113 and the connecting member 340 or the mounting base 100 is relatively fixed. This structural setting can conveniently adjust the angle between the lifting module 311 and the mounting base 100, for example, adjust the angle between the first direction and the mounting base 100, thereby improving the convenience of assembly.

[0043] The above tooth mold mounting mechanism 300 can be used in the oral cleaning influencing factor analysis device 10. The tooth mold mounting mechanism 300 includes an adjustment component 310 and a sensor module 320. The sensor module 320 is connected to the output end of the adjustment component 310 and is used to detachably connect to the tooth mold 20. The adjustment component 310 is used to adjust the position of the sensor module 320 and the tooth mold 20 so that the external brushing action simulation mechanism 200 can contact and clean the surface of the tooth mold 20. The sensor module 320 is used to detect the pressure exerted on the tooth mold 20 during the cleaning process. Since the tooth mold 20 is mounted on the sensor module 320, the sensor module 320 can detect the pressure exerted on the tooth mold 20 during the cleaning process. If the cleaning pressure is too large or too small, it can be appropriately adjusted. For example, it can be combined with automated means for real-time control to control the cleaning pressure within the required range to approximate the actual brushing scene and ensure the accuracy and credibility of the oral cleaning influencing factor analysis results.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
