Description

Technical Field

[0001] The present application relates to the field of oral scanning technology, and more specifically, to an oral scanning device. Background Art

[0002] Oral scanning devices typically include an energy receiving module (e.g., a camera) that captures intraoral images (e.g., images of teeth) to analyze the user's oral condition and promptly identify oral problems. When a user uses an oral scanning device to scan their oral cavity, the energy receiving module has a specific focal length / range. This makes it difficult to control the distance between the energy receiving module and the teeth / gums during use, leading to out-of-focus conditions and an inability to accurately capture the oral condition from the captured image.

[0046] An oral scanning device generally includes an energy receiving module (e.g., a camera), which is used to obtain images of the oral cavity (e.g., images of teeth) to analyze the user's oral condition based on the images and promptly detect oral problems. When a user uses an oral scanning device to scan the oral cavity, since the energy receiving module has a certain focal length / focal section, it is difficult to control the distance between the energy receiving module and the teeth / gums during use, and out-of-focus conditions may occur, resulting in an inability to accurately obtain the oral condition from the captured image. In order to solve this problem, an embodiment of the present application provides an oral scanning device 100 ( Figure 1 shown).

[0047] See also Figure 1 and Figure 2The oral scanning device 100 according to an embodiment of the present application includes a main unit 10 and an opening assembly 30. The main unit 10 is provided with an energy receiving module 11, which is used to receive energy reflected from the part of the oral cavity to be scanned. The opening assembly 30 is connected to the main unit 10 and surrounds the energy receiving module 11. The opening assembly 30 has through-holes 31 extending through opposite ends thereof, with the energy receiving module 11 corresponding to the through-holes 31. The end of the opening assembly 30 facing away from the main unit 10 is designed to abut any part of the oral cavity, so that the part to be scanned is within the depth of field of the energy receiving module 11.

[0048] Specifically, the oral cavity scanning device 100 is used to scan the oral cavity of a user. By acquiring an intraoral image, the user's current oral condition can be analyzed based on the image, so that the user can find oral problems in a timely manner.

[0049] The host computer 10 is used to scan and examine the user's oral cavity. The oral areas to be scanned include, but are not limited to, the teeth and gums. When the oral scanning device 100 is in operation, the energy receiving module 11 can capture images of the teeth and / or gums within the oral cavity. Other components within the host computer 10 can analyze the images captured by the energy receiving module 11 to determine the current condition of the user's oral cavity. The user can also intuitively understand the current condition of their oral cavity through the images captured by the energy receiving module 11.

[0050] In one example, the energy receiving module 11 can be a two-dimensional camera module. In this case, the two-dimensional camera module includes a lens and an image sensor. The lens collects light within the field of view (light from the area to be scanned) and transmits the light to the image sensor. The image sensor converts the light signal into an electrical signal, and after a series of conversions, it finally forms a two-dimensional image. For example, the energy receiving module 11 can be a two-dimensional infrared camera module. In this case, the light-emitting module 15 of the host 10 can be used to emit infrared light. The infrared light emitted by the light-emitting module 15 is irradiated onto the area to be scanned. The interior of the oral cavity will reflect a portion of the infrared light. The infrared camera module captures the reflected infrared light and converts it into a digital signal. After the digital signal is processed by a computer, an infrared image can be generated. For another example, the energy receiving module 11 can be a two-dimensional ultraviolet camera module. In this case, the light-emitting module 15 is used to emit ultraviolet light. The ultraviolet light emitted by the light-emitting module 15 is irradiated onto the part to be scanned. The internal part of the oral cavity will reflect a part of the ultraviolet light. The ultraviolet camera module captures the reflected ultraviolet light and converts it into a digital signal. After the digital signal is processed by the computer, an ultraviolet image can be generated.

[0051] In another example, the energy receiving module 11 may be a time-of-flight camera. The time-of-flight camera first emits a laser pulse onto the part to be scanned. The laser pulse then reaches the object and is reflected back. The time-of-flight camera calculates the distance from the part to be scanned to the camera based on the time it takes for the pulse to be emitted and the time it takes for it to be reflected, thereby forming a three-dimensional image. This application uses the energy receiving module 11 as an example of a two-dimensional camera module.

[0052] The opening assembly 30 is detachably or non-detachably connected to the host 10. The opening assembly 30 includes a first end and a second end opposite to each other. The first end 301 of the opening assembly is connected to the host 10, and the second end 303 of the opening assembly is a free end. A through hole 31 passes through the first end 301 and the second end of the opening assembly. The opening assembly 30 is used to maintain a certain distance between the energy receiving module 11 and the part to be scanned, avoiding the problem of out-of-focus caused by the energy receiving module 11 being too close to the part to be scanned. The opening assembly 30 is a roughly annular structure, and the energy receiving module 11 can capture an image of the part to be scanned through the through hole 31.

[0053] See also Figure 2 When the oral scanning device 100 needs to scan the oral cavity, the second end 303 of the opening component can be pressed against the user's gums or teeth so that the part to be scanned corresponds to the through hole 31, and the energy receiving module 11 can capture an image of the part to be scanned through the through hole 31. Since the opening component 30 creates a certain distance between the part to be scanned and the energy receiving module 11, the part to be scanned can be located within the depth of field of the energy receiving module 11, so that the image captured by the energy receiving module 11 is clearer. Other components inside the host 10 can accurately obtain the current oral condition from the captured image, and the user can also intuitively obtain the current oral condition from the captured image, and the scanning effect of the oral scanning device 100 is better. Among them, the depth of field refers to the front and back distance range of the object to be scanned measured by the imaging at the front of the energy receiving module to obtain a clear image.

[0054] In the oral scanning device 100 of the embodiment of the present application, when a user is scanning the oral cavity, the end of the opening component 30 away from the main body 10 abuts against any part of the oral cavity, thereby maintaining a certain distance between the energy receiving module 11 and the part to be scanned, and the part to be scanned is within the depth of field of the energy receiving module 11. In this case, when the energy receiving module 11 captures an image of the part to be scanned through the through hole 31, the image captured by the energy receiving module 11 is relatively clear and less likely to be out of focus, allowing the user to accurately understand the current oral condition from the captured image.

[0055] The oral scanning device 100 will be further described below with reference to the accompanying drawings.

[0056] See also Figure 2 In some embodiments, when the opening assembly 30 abuts the part to be scanned, the second end 303 of the opening assembly is located within the depth of field of the energy receiving module 11. In this case, when the part to be scanned contacts the second end 303 of the opening assembly, the part to be scanned can be located within the depth of field of the energy receiving module 11, so that the image of the part to be scanned captured by the energy receiving module 11 can be clearer.

[0057] See also Figures 1 to 3 In some embodiments, the opening component 30 gradually expands outward in the direction from the first end 301 to the second end 303 .

[0058] Because the field of view of the energy receiving module 11 is generally outwardly expanding, as the opening assembly 30 gradually expands from the first end 301 of the opening assembly to the second end 303 of the opening assembly, the problem of the peripheral walls of the opening assembly 30 obstructing the field of view of the energy receiving module 11 can be effectively avoided. The field of view of the energy receiving module 11 is relatively large, and the energy receiving module 11 can clearly capture an image of the area to be scanned. If the peripheral walls of the opening assembly 30 obstruct the field of view of the energy receiving module 11, the energy receiving module 11 may receive energy reflected back by the peripheral walls of the opening assembly 30, and the energy receiving module 11 may not be able to obtain a full image of the area to be scanned. The peripheral walls of the opening assembly 30 may affect the image acquisition of the energy receiving module 11.

[0059] When a user applies external force to the oral scanning device 100 to hold the second end 303 of the opening assembly against the interior of the oral cavity, if the force applied is significant, the opening assembly 30 may deform to some extent. As the opening assembly 30 gradually expands outward from the first end 301 to the second end 303 of the opening assembly, the deformation of the opening assembly 30 tends to expand outward, further preventing the peripheral wall of the opening assembly 30 from obstructing the field of view of the energy receiving module 11. The energy receiving module 11 can effectively capture images of the scanned area.

[0060] See also Figure 1 and Figure 2In certain embodiments, the outer side surface of the second end 303 of the opening component is an arc surface; and / or, the thickness of the second end 303 of the opening component is greater than the thickness of the first end 301 of the opening component. In the case where the outer side surface of the second end 303 of the opening component is an arc surface, and the thickness of the second end 303 of the opening component is greater than the thickness of the first end 301 of the opening component, when the second end 303 of the opening component is extended into the oral cavity to abut against the internal part of the oral cavity, the second end 303 of the opening component is not easy to scratch the oral cavity, and the user's user experience is better. Moreover, when the second end 303 of the opening component abuts against the part inside the oral cavity, the second end 303 of the opening component is not easy to deform, thereby avoiding the problem of the second end 303 of the opening component blocking the field of view of the energy receiving module 11.

[0061] See also Figure 1 and Figure 2 In certain embodiments, in the axial direction X of the energy receiving module 11, the opening assembly 30 is connected to the host 10 in a floating or sliding manner to change the distance between the energy receiving module 11 and the second end 303 of the opening assembly. Since each user has different habits in using the oral scanning device 100, for example, when the part to be scanned is a tooth, the user can make the second end 303 of the opening assembly abut against the gums, and the user can also make the second end 303 of the opening assembly abut against the teeth. When the second end 303 of the opening assembly abuts against the gums and against the teeth, the distance between the energy receiving module 11 and the part to be scanned is different. When the opening assembly 30 is connected to the host 10 in a floating or sliding manner, the distance between the second end 303 of the opening assembly and the energy receiving module 11 can be adjusted so that the part to be scanned can be located within the depth of field of the energy receiving module 11, so that the image of the part to be scanned taken by the energy receiving module 11 is clearer.

[0062] See also Figure 2 and Figure 3 In some embodiments, the opening assembly 30 includes a support member 33, one end of which is connected to the host 10, and the support member 33 is used to maintain the shape of the opening assembly 30 when subjected to external force.

[0063] The hardness of the support member 33 can be relatively large, so that the connection between the support member 33 and the host 10 is relatively stable, and the support member 33 is not easy to fall off relative to the host 10. When the opening component 30 is extended into the oral cavity and when the opening component 30 is extended from the oral cavity, the opening component 30 is not easy to loosen relative to the host 10. In addition, the support member 33 is not easy to deform when subjected to external force, so that when the opening component 30 is against the inner part of the oral cavity, the opening component 30 is not easy to deform, thereby avoiding the problem of the peripheral wall of the opening component 30 blocking the field of view of the energy receiving module 11. When the support member 33 is almost not deformed, the length of the support member 33 is not easy to change in the axial direction X of the energy receiving module 11, so that when the opening component 30 is against the inner part of the oral cavity, a certain distance can be maintained between the part to be scanned and the energy receiving module 11. When the opening assembly 30 is subjected to a large external force, the distance between the part to be scanned and the energy receiving module 11 will not be shortened too much, which can avoid the problem that the distance between the part to be scanned and the energy receiving module 11 is too small, and the part to be scanned is outside the depth of field of the energy receiving module 11, resulting in the image of the part to be scanned taken by the energy receiving module 11 not being clear enough.

[0064] See also Figure 2 and Figure 3 Specifically, the support member 33 includes a main body 333 and a connecting portion 335. The main body 333 includes a first end 3331 and a second end 3333. The first end 3331 is farther away from the host 10 than the second end 3333. The connecting portion 335 extends from the second end 3333 away from the main body 333 and is connected to the host 10.

[0065] The main body 333 is used to maintain a certain distance between the energy receiving module 11 and the part to be scanned, so that the part to be scanned is within the depth of field of the energy receiving module 11. The second end 3333 of the main body surrounds the energy receiving module 11. When the oral scanning device 100 is scanning the oral cavity, the first end 3331 of the main body is closer to the oral cavity. The main body 333 is used to form the through hole 31. The connecting portion 335 is used to connect to the host 10, thereby ensuring a more stable connection between the opening assembly 30 and the host 10. The opening assembly 30 is not easily displaced relative to the host 10, thereby preventing the surrounding walls of the opening assembly 30 from obstructing the field of view of the energy receiving module 11.

[0066] The main body 333 and the connecting portion 335 can be integral or separate. If the main body 333 and the connecting portion 335 are integral, they can be integrally formed. If the main body 333 and the connecting portion 335 are separate, they can be detachably or non-detachably connected. Removable mounting methods include, but are not limited to, threaded connections, screw connections, or snap-fit connections. Non-detachable mounting methods include, but are not limited to, welding, gluing, or interference fit.

[0067] See also Figure 2 Furthermore, in some embodiments, the support member 33 also includes an abutment portion 337, which extends from the second end 3333 of the main body toward the direction close to the axis of the opening assembly 30, and the abutment portion 337 abuts against the host 10.

[0068] When the abutting portion 337 abuts the host 10, the cooperation between the abutting portion 337 and the host 10 can, on the one hand, position the support member 33, making the installation between the opening assembly 30 and the host 10 more convenient and quick, and avoiding the problem of misalignment between the opening assembly 30 and the host 10. On the other hand, the connection between the abutting portion 337 and the host 10 can further stabilize the connection between the support member 33 and the host 10, thereby preventing the opening assembly 30 from shifting relative to the host 10, and further preventing the peripheral wall of the opening assembly 30 from blocking the field of view of the energy receiving module 11.

[0069] The main body 333 and the abutting portion 337 can be integral or separate. If the main body 333 and the abutting portion 337 are integral, they can be integrally formed. If the main body 333 and the abutting portion 337 are separate, they can be detachably or non-detachably connected. Removable mounting methods include, but are not limited to, threaded, screw, or snap-fit connections. Non-detachable mounting methods include, but are not limited to, welding, gluing, or interference fit.

[0070] See also Figure 2In some embodiments, a soft rubber pad is provided at the end of the support member 33 away from the host 10, that is, the first end 3331 of the main body is connected to the soft rubber pad. When the oral scanning device 100 is scanning the oral cavity, the first end 3331 of the main body is closer to the oral cavity. Due to the greater hardness of the support member 33, when the support member 33 is inserted into the oral cavity and abuts against a part inside the oral cavity between the first end 3331 of the main body, the first end 3331 of the main body may scratch the user's oral cavity, resulting in poor user comfort. When the first end 3331 of the main body is provided with a soft rubber pad, when the oral scanning device 100 is scanning the oral cavity, the soft rubber pad can be inserted into the oral cavity and abut against a part inside the oral cavity. The material of the soft rubber pad is relatively soft and is not easy to scratch the oral cavity, thereby providing better user comfort. The connection method between the soft rubber pad and the first end 3331 of the main body can be, but is not limited to, gluing, interference fit, or snap-fit.

[0071] See also Figure 2 and Figure 3 In other embodiments, the opening assembly 30 further includes a deformable member 35, at least a portion of which is sleeved on the support member 33, and a free end of the deformable member 35 is further away from the host 10 than the free end of the support member 33, and the deformable member 35 can be deformed by external force.

[0072] When the oral scanning device 100 is scanning the oral cavity, the free end of the deformable member 35 is used to extend into the oral cavity to contact an area therein. Because the deformable member 35 can be deformed by external forces and is made of a relatively soft material, when the deformable member 35 contacts an area within the oral cavity, it is unlikely to scratch the user's mouth, providing a better user experience.

[0073] In one embodiment, the deformable member 35 is only sleeved on the first end 3331 of the main body. In this case, the material used for the deformable member 35 is less, which can save material costs. In another embodiment, the deformable member 35 wraps the entire support member 33, and the free end of the deformable member 35 is farther away from the host 10 than the first end 3331 of the main body, and the deformable member 35 and the support member 33 together form a through hole 31. In this case, the deformable member 35 can better protect the support member 33, and the support member 33 is not easily scratched or bumped by external objects, and the service life of the support member 33 is longer. Moreover, at this time, the material of the entire outer surface of the opening component 30 is relatively soft. When the opening component 30 is extended into the oral cavity, the opening component 30 is not easy to scratch the oral cavity, and the user's comfort is better. The deformable member 35 of the embodiment of the present application wraps the entire support member 33.

[0074] See also Figure 2 and Figure 3In some embodiments, the deformable member 35 is a soft rubber, and the hardness of the support member 33 is greater than the hardness of the deformable member 35. The material of the support member 33 includes but is not limited to hard plastic and metal. The material of the deformable member 35 includes but is not limited to rubber, silicone and flexible plastic. When the hardness of the support member 33 is relatively high, the support member 33 can maintain the shape of the opening component 30. When the opening component 30 is against the inside of the oral cavity, the opening component 30 is not easy to deform, thereby preventing the peripheral wall of the opening component 30 from blocking the field of view of the energy receiving module 11. When the hardness of the deformable member 35 is relatively low, when the opening component 30 is against the inside of the oral cavity, the deformable member 35 is not easy to scratch the oral cavity, and can play a better protective role for the oral cavity.

[0075] See also Figure 2 In some embodiments, in the axial direction X of the energy receiving module 11, the distance between the free end of the deformable member 35 and the focal point of the energy receiving module 11 ranges from 0 mm to 5 mm. For example, the distance between the free end of the deformable member 35 and the focal point of the energy receiving module 11 can be, but is not limited to, 1 mm, 1.6 mm, 2.5 mm, 2.6 mm, 3.2 mm, 3.3 mm, 3.9 mm, 4.1 mm, 4.6 mm, 5.0 mm, etc.

[0076] When the opening assembly 30 is held in place within the oral cavity by an external force, the deformable member 35 deforms in the axial direction X of the energy receiving module 11, thereby shortening the distance between the scanned portion and the energy receiving module 11. When the distance between the free end of the deformable member 35 and the focal point of the energy receiving module 11 is in the range of [0 mm, 5 mm], after the deformable member 35 undergoes a certain amount of deformation in the axial direction X of the energy receiving module 11, the scanned portion remains within the depth of field of the energy receiving module 11, resulting in a clearer image of the scanned portion captured by the energy receiving module 11.

[0077] When the distance between the free end of the deformable member 35 and the focus of the energy receiving module 11 is greater than 5 mm, the distance between the free end of the deformable member 35 and the energy receiving module 11 is relatively far. Even if the deformable member 35 is deformed to a certain extent in the axial direction X of the energy receiving module 11 by external force, the part to be scanned will be outside the depth of field of the energy receiving module 11. At this time, the image of the part to be scanned taken by the energy receiving module 11 is prone to out-of-focus problems, and the image is not clear enough, so that the user cannot accurately obtain the oral condition.

[0078] See also Figure 2 and Figure 3In some embodiments, the deformable member 35 includes a main body portion 353 and a reinforcement portion 355 connected to each other, the reinforcement portion 355 is arranged at an end of the main body portion 353 away from the host 10, and the thickness of the reinforcement portion 355 is greater than the thickness of the main body portion 353; and / or, the outer side surface of the reinforcement portion 355 is a curved surface.

[0079] The main body 353 is sleeved onto the support member 33 and extends away from the main body 10 relative to the first end 3331 of the main body. The main body 353 protects the support member 33 and deforms when the opening assembly 30 is subjected to force. When the opening assembly 30 is subjected to external force applied by the user, part of the force causes the deformable member 35 to press against the oral cavity, while the remaining force causes the main body 353 to deform. This reduces the pressure exerted by the opening assembly 30 against the oral cavity, making it less likely to cause damage to the oral cavity and providing a better user experience.

[0080] The reinforcement portion 355 is located at the free end of the main body 353, away from the main unit 10. The reinforcement portion 355 is used to contact the oral cavity. If the thickness of the reinforcement portion 355 is greater than that of the main body 353, the reinforcement portion 355 is less likely to deform when contacting the oral cavity. If the outer surface of the reinforcement portion 355 is curved, the reinforcement portion 355 is less likely to scratch the oral cavity when contacting the oral cavity, providing a better user experience.

[0081] The main body 353 and the reinforcement portion 355 can be integral or separate. If the main body 353 and the reinforcement portion 355 are integral, they can be integrally formed. If the main body 353 and the reinforcement portion 355 are separate, they can be detachably or non-detachably connected. Removable mounting methods include, but are not limited to, threaded connections, screw connections, or snap-fit connections. Non-detachable mounting methods include, but are not limited to, welding, gluing, or interference fit.

[0082] See also Figure 2 and Figure 3 Furthermore, in some embodiments, the deformable member 35 also includes a blocking portion 357, which bends and extends from one end of the main body 353 close to the host 10 toward the support member 33, and the blocking portion 357 abuts against the outer surface of the host 10.

[0083] The blocking portion 357 extends from the end of the main body 353 that is away from the reinforcing portion 355. While wrapping around the free end of the connecting portion 335, the blocking portion 357 abuts the main unit 10. The blocking portion 357 is used to prevent water and / or saliva from entering the intraoral scanning device 100 through the gap between the blocking portion 357 and the main unit 10. This prevents water and / or saliva from obstructing the field of view of the energy receiving module 11 and preventing water and / or saliva from entering the main unit 10 and damaging it.

[0084] The main body 353 and the barrier 357 can be integral or separate. If the main body 353 and barrier 357 are integral, they can be integrally formed. If the main body 353 and barrier 357 are separate, they can be detachably or non-detachably connected. Removable mounting methods include, but are not limited to, threaded, screw, or snap-fit connections. Non-detachable mounting methods include, but are not limited to, welding, gluing, or interference fit.

[0085] See also Figure 2 and Figure 3 In some embodiments, at least a portion of the outer wall of the support member 33 is recessed toward the inner wall to form a mating portion 331. The inner wall of the deformable member 35 protrudes away from the outer wall of the deformable member 35 to form a coupling portion 351. The coupling portion 351 cooperates with the mating portion 331 to connect the deformable member 35 to the support member 33. The mating portion 331 is a groove formed by a recess in the outer wall of the main body 333. The coupling portion 351 is a protrusion protruding from the inner wall of the main body 353. When the coupling portion 351 extends into the mating portion 331, the connection between the deformable member 35 and the support member 33 is more stable.

[0086] See also Figure 3 Specifically, in some embodiments, a plurality of spaced reinforcing ribs 3311 are provided in the mating portion 331, and the plurality of reinforcing ribs 3311 separate the mating portion 331 into a plurality of sub-mating portions 3313. The coupling portion 351 includes a plurality of spaced sub-combining portions 3511, and the plurality of sub-combining portions 3511 are respectively matched with the plurality of sub-mating portions 3313 to connect the deformable member 35 with the support member 33.

[0087] The mating portion 331 can be a full-circle groove recessed from the outer wall of the support member 33. If multiple reinforcing ribs 3311 are provided within the mating portion 331, the reinforcing ribs 3311 can enhance the overall strength of the support member 33 and prevent deformation of the support member 33 when subjected to external forces. For example, the number of sub-mating portions 3313 can be, but is not limited to, two, three, four, five, or more, and the number of sub-joining portions 3511 is the same as the number of sub-mating portions 3313. If there are five sub-mating portions 3313, the number of reinforcing ribs 3311 is also five. The five reinforcing ribs 3311 divide the mating portion 331 into five sub-mating portions 3313, and in this case, the number of sub-joining portions 3511 is also five. When multiple sub-combining parts 3511 are respectively matched with multiple sub-matching parts 3313, the reinforcing rib 3311 is also used to increase the friction between the sub-combining parts 3511 and the sub-matching parts 3313. The friction force between the combining part 351 and the matching part 331 is relatively large, so that the connection between the deformable part 35 and the supporting part 33 is more stable, and the deformable part 35 and the supporting part 33 are not easy to become loose relative to each other.

[0088] See also Figure 2 In some embodiments, the edge of the field of view of the energy receiving module 11 is spaced from the side wall of the deformable member 35 , and the distance between them in the extension direction of the side wall of the deformable member 35 is greater than 2 mm.

[0089] For example, the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the deformable member 35 may be 2.2 mm, 3.6 mm, 4.1 mm, 5.7 mm, 6.6 mm, 7.1 mm, 8.3 mm, 8.5 mm, 9.2 mm, or 10.3 mm. When the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the deformable member 35 is greater than 2 mm, when the deformable member 35 is in contact with the interior of the oral cavity and deformed to a certain extent by an external force, the structure of the deformable member 35 will not enter the field of view of the energy receiving module 11. That is, the deformable member 35 is unlikely to block the field of view of the energy receiving module 11, and the energy receiving module 11 can effectively capture images of the area to be scanned.

[0090] See also Figure 2 In some embodiments, in the extension direction of the side wall of the deformable member 35, the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the support member 33 is smaller than the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the deformable member 35.

[0091] Because the support member 33 is relatively hard, when the opening assembly 30 is against the interior of the oral cavity, the support member 33 is not easily deformed by external forces. Therefore, the distance between the edge of the field of view of the energy receiving module 11 and the sidewall of the support member 33 can be relatively small, and the support member 33 is not easily deformed to block the field of view of the energy receiving module 11. For example, the distance between the edge of the field of view of the energy receiving module 11 and the sidewall of the support member 33 can be 0.5 mm, 0.7 mm, 0.8 mm, 1.2 mm, or 1.8 mm, etc.

[0092] The material of the deformable member 35 is relatively soft, and when the opening assembly 30 is positioned against the interior of the oral cavity, the support member 33 is easily deformed by external forces. If the distance between the edge of the field of view of the energy receiving module 11 and the sidewall of the deformable member 35 is greater than the distance between the edge of the field of view of the energy receiving module 11 and the sidewall of the support member 33, that is, if the distance between the edge of the field of view of the energy receiving module 11 and the sidewall of the deformable member 35 is large (greater than 2 mm), the deformable member 35 can be deformed by external forces without obstructing the field of view of the energy receiving module 11.

[0093] When the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the support member 33 is smaller than the distance between the edge of the field of view of the energy receiving module 11 and the side wall of the deformable member 35, the size of the support member 33 can be smaller, so that the size of the opening component 30 is smaller, which can facilitate the opening component 30 to be extended into the oral cavity.

[0094] See also Figure 1 and Figure 2 In some embodiments, the inner wall surface of the support member 33 and the inner wall surface of the deformable member 35 are smoothly transitioned. In this case, the overall wall thickness of the opening component 30 is relatively uniform, the opening component 30 is relatively easy to clean, and the overall aesthetics of the opening component 30 are better.

[0095] See also Figure 2 and Figure 3 In some embodiments, the host 10 further includes a shell 12 and a cover 13, the energy receiving module 11 is installed in the shell 12, and the cover 13 is connected to one end of the shell 12 close to the opening component 30; the connecting portion 335 surrounds the cover 13 and is connected to the cover 13.

[0096] The housing 12 is used to mount the energy receiving module 11 and other components of the host 10. The housing 12 also protects the energy receiving module 11 from collisions with external objects, thereby extending the service life of the energy receiving module 11. The cover 13 is fixedly connected to the housing 12. The connection between the cover 13 and the housing 12 may be, but is not limited to, gluing, welding, interference fit, or snap-fit connection. The cover 13 is connected to the connecting portion 335 to securely connect the opening assembly 30 to the host 10, preventing the opening assembly 30 from shifting or falling off relative to the host 10.

[0097] See also Figure 3 Specifically, in some embodiments, the side wall of the connection portion 335 facing the cover body 13 is provided with a first connection portion 3351, and the side wall of the cover body 13 facing the connection portion 335 is provided with a second connection portion 131. The first connection portion 3351 cooperates with the second connection portion 131 to connect the support member 33 to the cover body 13.

[0098] See also Figure 3 In some embodiments, the first connection 3351 cooperates with the second connection 131 to limit the freedom of the opening assembly 30 and the host 10 in the axial direction X of the energy receiving module 11 and / or the circumferential direction of the oral scanning device 100.

[0099] Preferably, the first connection 3351 cooperates with the second connection 131 to limit the degrees of freedom of the opening assembly 30 and the mainframe 10 in the axial direction X of the energy receiving module 11, and also in the circumferential direction of the oral scanning device 100. This effectively prevents the opening assembly 30 from rotating, shifting, or falling off relative to the mainframe 10, thereby preventing the peripheral wall of the opening assembly 30 from obstructing the field of view of the energy receiving module 11, and providing a more stable connection between the opening assembly 30 and the mainframe 10.

[0100] See also Figure 3 In some embodiments, the first connection 3351 is provided with a protrusion, and the second connection 131 is provided with a groove, and the protrusion cooperates with the groove to connect the support member 33 to the cover body 13; the groove and the peripheral side of the cover body 13 have a smooth transition.

[0101] The number of protrusions can be, but is not limited to, one, two, three, four, or more. The number of grooves is the same as the number of protrusions. For example, if there is one protrusion, one protrusion may circumscribe the inner wall of the connecting portion 335, and if there is one groove, one groove may circumscribe the inner wall of the cover 13. In this case, the connection between the support member 33 and the cover 13 is more stable, and the processing of the support member 33 and the cover 13 is relatively simple. If there are multiple protrusions, the multiple protrusions may be spaced apart on the inner wall of the connecting portion 335. Preferably, the multiple protrusions may be evenly distributed on the inner wall of the connecting portion 335. In this case, when the multiple protrusions are connected to the multiple grooves, the force at the connection between the cover 13 and the support member 33 is more uniform, and the connection between the cover 13 and the support member 33 is more stable. For example, if there are two protrusions, the two protrusions may be symmetrically distributed on the inner wall of the connecting portion 335, and the two grooves may be symmetrically distributed on the outer wall of the cover 13. The two protrusions cooperate with the two grooves respectively to firmly connect the cover 13 and the support member 33 .

[0102] In the case where the groove and the peripheral side surface of the cover body 13 have a smooth transition, the cover body 13 is easier to clean, and the problem of mold caused by liquid or dirt on the cover body 13 can be effectively avoided.

[0103] See also Figure 2 In some embodiments, a blocking portion is provided at one end of the connecting portion 335 away from the main body 333. The blocking portion bends and extends from the end of the connecting portion 335 toward the main unit 10, abutting against the outer surface of the main unit 10. The blocking portion can be used to prevent water and / or saliva from entering the intraoral scanning device 100 through the gap between the blocking portion and the main unit 10, thereby preventing water and / or saliva from obstructing the field of view of the energy receiving module 11 and preventing water and / or saliva from entering the main unit 10 and damaging it.

[0104] See also Figure 2 In some embodiments, the host 10 further includes a light-transmitting member 14 , which is connected to both the housing 12 and the cover 13 , and corresponds to the energy receiving module 11 . The abutting portion 337 abuts against a side of the light-transmitting member 14 away from the energy receiving module 11 .

[0105] The light-transmitting member 14 is used to protect the energy receiving module 11 and prevent water, saliva, dust, etc. from entering the energy receiving module 11, thereby blocking the field of view of the energy receiving module 11 and even damaging the energy receiving module 11. Preferably, the light transmittance of the light-transmitting member 14 can be relatively high, so that the energy receiving module 11 can capture an image of the part to be scanned through the light-transmitting member 14. The material of the light-transmitting member 14 can be, but is not limited to, glass, organic glass, acrylic, or a light-transmitting film. When the abutting portion 337 abuts against the light-transmitting member 14, the abutting portion 337 can firmly connect the light-transmitting member 14 to the cover body 13, thereby keeping the relative position of the light-transmitting member 14 and the energy receiving module 11 fixed, and preventing the light-transmitting member 14 from shifting relative to the energy receiving module 11. In addition, when the abutting portion 337 abuts against the light-transmitting member 14 , the abutting portion 337 can effectively prevent water or saliva from entering the host 10 through the gap between the light-transmitting member 14 and the cover 13 , thereby preventing components within the host 10 from being damaged.

[0106] See also Figure 2 and Figure 3 In some embodiments, in the axial direction X of the energy receiving module 11, the distance between the abutment portion 337 and the end of the connecting portion 335 is less than or equal to 10 mm. In this case, the cleaning of the support member 33 is relatively convenient. For example, in the axial direction X of the energy receiving module 11, the distance between the abutment portion 337 and the end of the connecting portion 335 may be 1.0 mm, 3.3 mm, 5.6 mm, or 8.2 mm, etc. In the case that in the axial direction X of the energy receiving module 11, the distance between the abutment portion 337 and the end of the connecting portion 335 is greater than 10 mm, cleaning of the support member 33 is relatively difficult, and the user experience is poor.

[0107] See also Figure 2 and Figure 3 In some embodiments, the surface of the cover 13 transitions smoothly with the surface of the housing 12. In this case, when water or saliva flows onto the host 10, the host 10 can be easily cleaned, avoiding the problem of mold caused by liquid or dirt on the host 10.

[0108] See also Figure 2 and Figure 3 In some embodiments, the host 10 further includes a light-emitting module 15, which is distributed around the energy receiving module 11; the inner wall surface of the opening component 30 is a frosted surface, a non-reflective surface or a non-transparent surface, and the inner wall surface of the opening component 30 can prevent the light emitted by the light-emitting module 15 from being excessively reflected on the inner wall surface of the opening component 30 and / or prevent the light emitted by the light-emitting module 15 from being emitted through the peripheral wall of the opening component 30.

[0109] When the energy receiving module 11 is photographing the area to be scanned within the oral cavity, the light emitting module 15 is used to emit light to illuminate the area to be scanned, so that the energy receiving module 11 can clearly capture an image of the area to be scanned. In the case where the inner wall surface of the opening component 30 is a non-transparent surface, almost all of the light emitted by the light emitting module 15 can pass through the through hole 31 to illuminate the area to be scanned, thereby preventing the light of the light emitting module 15 from being emitted from the side wall of the opening component 30, resulting in a waste of light. In the case where the inner wall surface of the opening component 30 is a frosted surface or a non-reflective surface, the problem of overexposure causing the image captured by the energy receiving module 11 to be unclear can be avoided.

[0110] See also Figures 1 to 3 In some embodiments, the host 10 further includes a button 16 and a charging port 17, the button 16 is connected to a side of the shell 12 close to the opening component 30 or the peripheral side of the shell 12; and / or, the charging port 17 is provided on a side of the shell 12 close to the opening component 30 or the peripheral side of the shell 12.

[0111] If the button 16 is connected to the side of the housing 12 near the opening assembly 30 or the peripheral side of the housing 12, when water or saliva contacts the opening assembly 30, the water or saliva will flow downward due to gravity and will not accumulate around the button 16, effectively preventing damage to the button 16. If the charging port 17 is located on the side of the housing 12 near the opening assembly 30 or the peripheral side of the housing 12, when water or saliva contacts the opening assembly 30, the water or saliva will flow downward due to gravity and will not accumulate around the charging port 17, effectively preventing damage to the charging port 17.

[0112] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no conflicts in the combination of these technical features, they should be considered to be within the scope of this specification. Furthermore, other implementations can be derived from the above-described embodiments, allowing for structural and logical substitutions and changes without departing from the scope of this disclosure.

[0113] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application.
