Description

Technical Field

[0001] This utility model relates to the field of oral hygiene technology, and in particular to a brushing action simulation mechanism and an oral hygiene influencing factor analysis device. Background Technology

[0002] Oral hygiene efficiency is affected by a variety of factors, such as the type of toothpaste and toothbrush, brushing motions, pressure, and duration. It is difficult for both general users and toothbrush manufacturers to know the magnitude of the effect of different brushing motions, brushing times, and pressures on oral hygiene efficiency. Therefore, users lack scientific guidance in these aspects when using electric toothbrushes or other oral hygiene devices. Similarly, manufacturers, when designing electric toothbrushes or other oral hygiene devices, often struggle to clearly understand the magnitude of the effects of various factors (such as shape, vibration intensity, and duration) on oral hygiene efficiency, potentially leading to a lack of clear design priorities and wasted costs on factors with low impact.

[0026] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] refer to Figure 1 and Figure 2This application discloses an oral cleaning influencing factor analysis device 10, which can be used to conduct experimental research on various factors affecting oral cleaning efficiency, and then statistically analyze the effect size of these factors, i.e., the degree of influence of these influencing factors on oral cleaning efficiency. For example, using the oral cleaning influencing factor analysis device 10 of this application, different electric toothbrushes or ordinary toothbrushes can be used to study the effect size of toothbrush type on oral cleaning efficiency. Similarly, different cleaning intensities, speeds, times, and movements can be used 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 more scientifically select various consumer products needed for oral cleaning, avoiding excessive spending on unimportant influencing factors. Of course, users can also adjust brushing movements, brushing time, etc., to improve oral cleaning efficiency. For manufacturers of oral cleaning equipment, the effect size of these factors can be used to design oral cleaning equipment more specifically, avoiding excessive investment in unimportant influencing factors, thereby optimizing design and saving costs.

[0030] Continue to refer to Figure 1 The oral hygiene influencing factor analysis device 10 includes a mounting base 100, a brushing action simulation mechanism 200, and a dental model mounting mechanism 300. Figure 1 , Figure 2 The mounting base 100 shown is a simplified structure, roughly rectangular in shape, with multiple arrayed mounting holes 101. The brushing motion simulation mechanism 200 and the tooth mold mounting mechanism 300 can be mounted on the mounting base 100, which provides support and limits the movement. Through the mounting holes 101 and fasteners such as bolts, their positions on the mounting base 100 can be easily adjusted, reducing assembly difficulty and improving assembly efficiency.

[0031] The dental mold mounting mechanism 300 is connected to the mounting base 100 and is used to mount the dental mold 20. The dental mold 20 can be fabricated using 3D scanning technology combined with 3D printing technology to obtain a model that more closely resembles the human physiological structure, thereby obtaining more accurate analysis results. (Reference) Figure 3 The dental model 20 may include a base 21 and multiple teeth 23 protruding from the base 21, arranged sequentially according to the shape of the jawbone arc. The shape of the junction between the base 21 and the teeth 23 closely resembles the surface shape of the gums, while the spaces between adjacent teeth 23 simulate the state of the gaps between human teeth. This model structure, which closely resembles the real physiological structure, is more conducive to obtaining accurate analysis results and makes the analysis results more reliable.

[0032] The brushing motion simulation mechanism 200 is used to simulate a user's teeth cleaning actions. It may include a moving component 210 and a rotating component 220 connected to the moving component 210. The moving component 210 is connected to the mounting base 100, and the rotating component 220 is used to detachably mount a teeth cleaning component (not shown). The teeth cleaning component is not limited to an electric toothbrush, but may also be a regular toothbrush, such as a common hard-handled straight-handled toothbrush.

[0033] The moving component 210 is used to drive the rotating component 220 and the tooth cleaning component to move back and forth along the arrangement direction of the multiple teeth 23. The rotating component 220 is used to drive the tooth cleaning component to rotate relative to the teeth 23 during the cleaning process. That is, the brushing action simulation mechanism 200 drives the tooth cleaning component to contact the surface of the dental mold 20 so as to clean the surface of the dental mold 20 by the tooth cleaning component.

[0034] refer to Figure 1 and Figure 2 The moving component 210 may include a first feed module 211 and a second feed module 213. The second feed module 213 is detachably connected to the output end of the first feed module 211 via fasteners such as bolts, thereby facilitating the disassembly and maintenance of the first feed module 211 and the second feed module 213. The rotating component 220 is also detachably connected to the output end of the second feed module 213 via fasteners such as bolts, thereby facilitating the disassembly and maintenance of the rotating component 220. The first feed module 211 is used to drive the second feed module 213 and the rotating component 220 to reciprocate along a first direction to simulate the user's lateral brushing action; the second feed module 213 is used to drive the rotating component 220 to move along a second direction to simulate the user's pressure action on the teeth through the dental cleaning device; the rotating component 220 is used to drive the dental cleaning device to rotate to simulate the user's oscillating brush head action during brushing.

[0035] In some embodiments, the first direction and the second direction are orthogonal, and the rotation axis of the rotating component 220 is parallel to the first direction. This arrangement makes it easier to control the positions of the first feed module 211, the second feed module 213, and the rotating component 220, improving the convenience of assembly and operation.

[0036] It is understood that in the embodiments of this application, parallelism and orthogonality should not be regarded as strictly geometric relationships, but the existence of engineering errors should be taken into account. For example, when the included angle between two lines is in the range of 85 degrees to 95 degrees, the two lines can be regarded as perpendicular in engineering. Of course, in other embodiments, the first direction and the second direction may not be orthogonal, the rotation axis of the rotating component 220 may also be set at an angle to the first direction, and the execution action of the brushing action simulation mechanism 200 can be adaptively adjusted.

[0037] The first feed module 211 may include a first driver 2111, a ball screw 2113 connected to the output end of the first driver 2111, and a first slide 2115 cooperating with the ball screw 2113. The ball screw 2113 is detachably connected to the mounting base 100, and the second feed module 213 is connected to the first slide 2115. The first slide 2115 is the output end of the first feed module 211. The first driver 2111 can be a stepper motor, which, in conjunction with the ball screw 2113, allows for relatively precise displacement control. When the output of the first driver 2111 drives the ball screw (not shown) inside the ball screw 2113 to rotate, the first slide 2115, which is coupled to the ball screw, can move along the length of the ball screw, thereby driving the second feed module 213 connected to the first slide 2115 and the rotating component 220 connected to the second feed module 213 to translate in the first direction, so as to move closer to or away from the gear mold 20.

[0038] refer to Figure 2 The second feed module 213 has a similar structure and working principle to the first feed module 211. For example, the second feed module 213 includes another driver 2131, another ball screw 2133, and a second slide 2135, which is the output end of the second feed module 213. The output end of the other driver 2131 is connected to the other ball screw 2133, the second slide 2135 cooperates with the other ball screw 2133, and the other ball screw 2133 is connected to the first slide 2115. The first feed module 211 drives the entire second feed module 213 to move along the first direction, while the other driver 2131 drives the second slide 2135 to move along the second direction through the other ball screw 2133, thereby driving the rotating assembly 220 and the dental cleaning component thereon to move along the second direction to approach or move away from the dental mold 20. Further details are omitted here.

[0039] Continue to refer to Figure 1 and combined Figure 4 The first feed module 211 may include a connector 2117 connected to the ball screw 2113. The connector 2117 is generally L-shaped and has a first oblong hole K1. Fasteners such as bolts can pass through the first oblong hole K1 and the mounting hole 101 of the mounting base 100 to detachably fix the ball screw 2113 to the mounting base 100 and facilitate adjustment of the relative position of the ball screw 2113 and the mounting base 100. For example, after adjusting the angle of the ball screw 2113 relative to the first direction, the second direction, and the distance relative to the gear mold mounting mechanism 300, fasteners can be passed through the first oblong hole K1 and inserted into the mounting hole 101 to reliably confine the first feed module 211 to the mounting base 100.

[0040] Furthermore, the connector 2117 may include an integrally formed first connecting portion 21171 and a second connecting portion 21173, which are perpendicular to each other. The first connecting portion 21171 has a first oblong hole K1, and the second connecting portion 21173 has a second oblong hole K2. The second oblong hole K2 is used to pass through a fastener and adjust the relative position of the ball screw 2113 and the second connecting portion 21173, thereby adjusting the position of the ball screw 2113 relative to the mounting base 100, such as adjusting the angle of the ball screw 2113 in the vertical direction. A connecting hole (not shown) for fixing may be provided on the ball screw 2113. After adjusting the relative position of the ball screw 2113 and the second connecting portion 21173, the fastener can be passed through the second oblong hole K2 and screwed into the connecting hole, so that the position of the ball screw 2113 relative to the connector 2117 or the mounting base 100 is fixed. This structural design allows for easy adjustment of the angle between the first feed module 211 and the mounting base 100, such as adjusting the tilt angle of the brushing action simulation mechanism 200 relative to the mounting base 100, thereby improving assembly convenience.

[0041] Continue to refer to Figure 2 The rotating assembly 220 includes a rotating driver 221, a chuck 223 connected to the output end of the rotating driver 221, and a support 225 detachably connected to the second slide 2135. The rotating driver 221 is connected to the second slide 2135, and the chuck 223 is connected to the support 225. The second feed module 213 is used to drive the rotating driver 221 and the chuck 223 to move along a second direction through the second slide 2135.

[0042] Simultaneously combined Figure 5 In one embodiment, the chuck 223 is a four-jaw chuck, one axial end of which can be used to hold an electric toothbrush or a regular toothbrush. The opposite axial end of the four-jaw chuck passes through the support base 225 and is linked to the output end of the rotary driver 221. The end of the four-jaw chuck extending into the support base 225 can be rotatably connected to the support base 225 through a bearing structure, so that the rotary driver 221 can drive the chuck 223 and the dental cleaning component on it to rotate relative to the dental mold 20. Of course, in other embodiments, the chuck 223 can take other forms, such as a three-jaw chuck.

[0043] Further, refer to Figure 6In some embodiments, the second feed module 213 includes a buffer 227 connected between the second slide 2135 and the support 225. The buffer 227 is deformed by the compression of the support 225 and the second slide 2135. The buffer 227 can be a silicone or rubber component, etc., connected between the support 225 and the second slide 2135 and deformed by the compression of the support 225 and the second slide 2135. Specifically, the support 225 can be detachably connected to the second slide 2135 by fasteners such as bolts or screws, with the fasteners passing through the buffer 227. Tightening or loosening the fasteners changes the compressive force of the support 225 on the buffer 227, and the elastic deformation of the buffer 227 changes accordingly, thereby achieving a slight increase or decrease in the position of the chuck 223 relative to the mounting base 100.

[0044] On the one hand, the buffer 227 can absorb the vibration impact of the chuck 223, preventing the vibration of the dental cleaning component and the chuck 223 from being directly transmitted to the ball screw of the second feed module 213 through the second slide 2135, reducing the impact on the ball screw structure, thereby extending the service life of the first feed module 211 and the second feed module 213.

[0045] On the other hand, the buffer 227 can be used to fine-tune the position of the chuck 223 relative to the gear mold 20, such as fine-tuning the angle between the rotation axis of the chuck 223 and the second direction, ensuring the parallelism between the rotation axis of the chuck 223 and the second direction. This structural design can reduce the assembly accuracy requirements of the chuck 223 in the second slide 2135, reduce the difficulty of processing, and reduce the impact of assembly errors on the analysis results, thereby ensuring the accuracy and reliability of the analysis results.

[0046] The brushing motion simulation mechanism 200 described above can be used in the oral hygiene influencing factor analysis device 10. The brushing motion simulation mechanism 200 includes a moving component 210 and a rotating component 220. The moving component 210 includes a first feed module 211 and a second feed module 213. The second feed module 213 is connected to the output end of the first feed module 211. The rotating component 220 is connected to the output end of the second feed module 213. The first feed module 211 is used to drive the second feed module 213 and the rotating component 220 to reciprocate along a first direction. The second feed module 213 is used to drive the rotating component 220 to move along a second direction. The rotating component 220 is used to detachably install the dental cleaning component and drive the dental cleaning component to rotate. The dental mold 20 can be mounted on an external dental mold mounting mechanism 300. The first moving component 210 drives the rotating component 220 and the dental cleaning component to reciprocate along a first direction. The rotating component 220 is used to drive the dental cleaning component to rotate relative to the dental mold 20 during the cleaning process to clean the surface of the dental mold 20. The automation of the brushing action simulation mechanism 200 is easy to achieve. The first moving component 210 and the rotating component 220 can more realistically simulate the brushing action and conveniently control factors such as cleaning force, speed, and time. Furthermore, different dental cleaning components such as electric toothbrushes or ordinary toothbrushes can be easily replaced through the rotating component 220, thereby conveniently adjusting these factors that affect oral cleaning efficiency, obtaining the effect quantities of these influencing factors, and providing clearer guidance for users or designers.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
