Description

Technical Field

[0001] The present application relates to the field of oral scanning technology, and in particular to a host of an oral scanning device and an oral scanning device. Background Art

[0002] Oral scanning devices typically consist of a light-transmitting element and a camera module. Light reflected from the oral cavity passes through the light-transmitting element and is received by the camera module. The light is processed by the camera module to form an image or video, which can be used to analyze the user's oral condition and identify oral problems promptly. However, in cold working environments, such as winter or mountainous areas, when a user uses an oral scanning device to scan the oral cavity, the light-transmitting element can become foggy due to the temperature difference, affecting the camera module's image quality. Utility Model Content

[0003] In view of the above problems, the present application provides a host of an oral scanning device and an oral scanning device.

[0004] The present application provides a host of an oral scanning device. The host includes a housing, a camera module, a light-transmitting element, and a heating module. The camera module is disposed in the housing and is used to receive light reflected from an interior portion of the oral cavity. The light-transmitting element is disposed in the housing and is used to transmit the light. The heating module is disposed in the housing and is spaced apart from the camera module in a direction perpendicular to the optical axis of the camera module. The heating module and the camera module are both opposite to the light-transmitting element in the direction of the optical axis. The heating module is capable of generating radiant energy to heat the light-transmitting element.

[0005] The host computer of this application generates radiant energy through a heating module to heat the light-transmitting element, allowing it to maintain a temperature close to that of the oral cavity. When a user uses an oral scanning device to scan the oral cavity, the temperature difference between the light-transmitting element and the oral cavity is small, thereby preventing the light-transmitting element from fogging due to cold. This ensures that light reflected from the interior of the oral cavity can pass through the light-transmitting element and be received by the camera module, thus ensuring the imaging quality of the camera module. In addition, if the light-transmitting element fogs up, the radiant energy generated by the heating module can increase the temperature of the light-transmitting element, accelerating the evaporation rate of the fog on the surface of the light-transmitting element, thereby improving the speed of defogging the surface of the light-transmitting element, and also ensuring the imaging quality of the camera module.

[0006] In some embodiments, the heating module is spaced apart from the light-transmitting member in the direction of the optical axis.

[0007] The heating module is spaced from the light-transmitting component, that is, the heating module is not in direct contact with the light-transmitting component. The heating module uses radiation energy to indirectly heat the light-transmitting component, which can make the light-transmitting component heated relatively more evenly and avoid local overheating.

[0008] In some embodiments, a first distance between the heating module and the light-transmitting element in the direction of the optical axis is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0009] The first distance is greater than or equal to 0.5 mm, which can ensure that there is a certain distance between the heating module and the light-transmitting component. The radiation energy generated by the heating module has a sufficient propagation range to evenly heat the light-transmitting component without local overheating. The first distance is less than or equal to 5 mm, which can reduce the propagation distance of the radiation energy to the light-transmitting component, thereby reducing the loss of radiation energy in the air and ensuring the heating efficiency of the heating module on the light-transmitting component.

[0010] In some embodiments, a first distance between the heating module and the light-transmitting member in the direction of the optical axis is smaller than a second distance between the camera module and the heating module in a direction perpendicular to the optical axis of the camera module.

[0011] The first distance is smaller than the second distance. On the one hand, it can reduce the propagation distance of the radiation energy to the light-transmitting component, thereby reducing the loss of the radiation energy in the air and ensuring the heating efficiency of the light-transmitting component by the heating module. On the other hand, it can increase the propagation distance of the radiation energy to the camera module, thereby preventing the radiation energy of the heating module from affecting the camera module, ensuring the constant temperature of the camera module, and avoiding damage to the camera module due to high temperature.

[0012] In some embodiments, the heating module includes a plurality of heating elements, and the plurality of heating elements are spaced apart and arranged around the periphery of the camera module.

[0013] Multiple heating elements surround the periphery of the camera module, which can form uniform radiation energy, ensuring that the radiation energy evenly heats the light-transmitting element, avoiding the problem of uneven surface temperature of the light-transmitting element, thereby avoiding fogging of the light-transmitting element due to temperature difference, and thus ensuring the imaging quality of the camera module.

[0014] In certain embodiments, the host further includes a sensor and a processor. The sensor is disposed within the housing and is configured to detect environmental data. The processor is disposed within the housing and outputs a degree of fogging of the light-transmitting member based on the environmental data. The heating module generates the radiant energy at a heating power and / or heating duration corresponding to the degree of fogging.

[0015] The sensor can detect environmental data, and the processor can determine the degree of fogging of the light-transmitting component based on the environmental data. As a result, the heating module can adaptively adjust the heating power and / or heating time according to the degree of fogging, so that the heating module can heat the light-transmitting component more accurately according to different environments, thereby achieving a better defogging effect on the light-transmitting component and saving energy.

[0016] In certain embodiments, the sensor comprises a temperature sensor, and the environmental data comprises a first temperature inside the housing and a second temperature outside the housing.

[0017] According to the first temperature and the second temperature, the temperature difference between the inside and outside of the shell can be obtained. When the temperature difference is large, the heating module can be automatically turned on to heat the light-transmitting element and defog the surface of the light-transmitting element.

[0018] In some embodiments, the sensor includes the camera module, and the environmental data includes image data captured by the light-transmitting element.

[0019] The camera module can obtain image data of the light-transmitting component. The image data carries the image features of the light-transmitting component. By digitally processing and analyzing the image features, it can be determined whether the light-transmitting component is fogged and the degree of fogging.

[0020] In some embodiments, the heating module further includes a partition disposed in the housing and separating the housing into a first cavity and a second cavity isolated from each other, wherein the heating module is accommodated in the first cavity.

[0021] The heating module is housed in the first cavity, which allows the radiation energy generated by the heating module to be relatively concentrated in the first cavity, maintaining the concentration of the radiation energy and reducing the radiation energy loss. In addition, the shell is divided into a first cavity and a second cavity that are isolated from each other, which can also prevent the radiation energy from dissipating into the second cavity, thereby preventing the components in the second cavity (such as the main board and / or power supply unit) from being affected by temperature.

[0022] In some embodiments, the host further includes a mainboard and / or a power supply unit, and the mainboard and / or the power supply unit are accommodated in the second cavity.

[0023] The mainboard and / or the power supply unit are accommodated in the second cavity, which can prevent the radiation energy generated by the heating module accommodated in the first cavity from affecting the operation of the mainboard and / or the power supply unit.

[0024] In certain embodiments, the heating element includes an LED lamp configured to emit light.

[0025] The LED lamp not only provides radiation energy and heats the light-transmitting parts to defog them, but also provides light. The light shines on the area inside the oral cavity, making the area within the imaging range of the camera module have a higher brightness, thereby ensuring the imaging quality of the camera module.

[0026] In some embodiments, the host further includes a heat insulating member. In the optical axis direction of the camera module, the heat insulating member is disposed between the light-transmitting member and the camera module and surrounds the camera module.

[0027] The heat insulation member is arranged between the light-transmitting member and the camera module. On the one hand, a part of the radiation energy emitted by the heating module can be radiated to the light-transmitting member to heat the light-transmitting member, thereby defogging the light-transmitting member; on the other hand, the heat insulation member can block part of the radiation energy emitted by the heating module from being radiated to the camera module, ensuring that the components of the camera module will not be affected by the temperature, thereby ensuring the imaging quality of the camera module.

[0028] In some embodiments, the thickness of the light-transmitting element is less than 2 mm.

[0029] The thickness of the light-transmitting element is less than 2 mm, which not only controls the weight and cost of the light-transmitting element within a reasonable range, but also enables the light-transmitting element to rise to the ideal temperature with less radiation energy, thus saving energy and time.

[0030] In certain embodiments, an anti-fog coating is provided on the light-transmitting member.

[0031] The anti-fog coating can reduce the condensation of water vapor on the surface of the light-transmitting component and prevent the light-transmitting component from fogging, thereby ensuring the light transmittance of the light-transmitting component and improving the imaging quality of the camera module.

[0032] In certain embodiments, the anti-fog coating comprises an anti-fog antimicrobial plastic coating.

[0033] The anti-fog and antibacterial plastic coating can maintain its own light transmittance at high temperatures, and can also inhibit the growth of bacteria on the surface of the anti-fog and antibacterial plastic coating, thereby extending its service life.

[0034] In some embodiments, the housing includes a base and a cover. The base is provided with a loading cavity and a light-transmitting hole communicating with the loading cavity, and the heating module and the camera module are both accommodated in the loading cavity. The cover is provided with a through hole and is mounted on the base. The through hole is correspondingly communicated with the light-transmitting hole, and the light-transmitting member is disposed in and covers the through hole.

[0035] The cover is provided with a through hole to provide installation space for the light-transmitting component. The through hole is connected to the light-transmitting hole, that is, the through hole and the light-transmitting hole are aligned in the direction of the optical axis of the camera module, which ensures that the light emitted by the heating module passes through the through hole and the light-transmitting hole without being blocked.

[0036] In some embodiments, the base includes a first base and a second base, and the first base and the second base are detachably connected.

[0037] The first base and the second base are detachably connected, which is convenient for maintenance and replacement of the first base and the second base.

[0038] In some embodiments, the base includes a base body and a boss, the boss extends from the base body, the light-transmitting hole passes through the base body and the boss, the cover is disposed on the boss, and the light-transmitting member is connected to the boss via an adhesive.

[0039] The boss extends from the base body—that is, it protrudes away from the base body. This simplifies alignment during cover installation, allowing the cover to be positioned directly over the boss, facilitating installation. Furthermore, once the cover is positioned over the boss, the boss restricts the cover's movement, preventing it from shifting. The light-transmitting element rests on the boss, providing support and further securing it, preventing displacement due to vibration or impact.

[0040] In some embodiments, within the projection plane in the optical axis direction, the projection of the adhesive member is located on the periphery of the projection of the heating module.

[0041] The projection of the bonding part is located on the periphery of the projection of the heating module, which can prevent the radiation energy radiated by the heating module in the direction of the optical axis from acting on the bonding part, reduce the influence of the radiation energy of the heating module on the bonding, and prevent the bonding part from losing viscosity or deformation due to temperature rise, thereby ensuring a stable connection between the light-transmitting part and the boss.

[0042] In some embodiments, the distance between the heating module and the bonding member is greater than the distance between the heating module and the light-transmitting member in the direction of the optical axis.

[0043] The small distance between the heating module and the light-transmitting part can reduce the propagation distance of the radiation energy to the light-transmitting part, thereby reducing the loss of radiation energy in the air and ensuring the heating efficiency of the light-transmitting part by the heating module; the large distance between the heating module and the bonding part can increase the propagation distance of the radiation energy to the bonding part, reduce the impact of the radiation energy of the heating module on the bonding part, and prevent the bonding part from losing viscosity or deformation due to temperature rise.

[0044] In some embodiments, the base body is provided with a through mounting hole, the mounting hole is arranged around the boss, the cover body is provided with a mounting piece, a fastener passes through the mounting hole and is connected to the mounting piece to connect the cover body to the base.

[0045] The fastener passes through the mounting hole and is connected to the mounting piece, so as to fix the cover body on the base. The mounting hole provides a location for the connection between the fastener and the mounting piece, so as to facilitate the connection between the fastener and the mounting piece.

[0046] In some embodiments, the host further includes a sealing member, which is sleeved on the fastener and located between the outer side wall of the fastener and the inner side wall of the mounting hole.

[0047] The seal seals the gap between the outer wall of the fastener and the inner wall of the mounting hole, preventing fluid from flowing into the main unit through the gap and improving the main unit's waterproof rating. Furthermore, the seal is low-cost and does not occupy additional installation space in the housing.

[0048] In some embodiments, the host further includes a motherboard disposed within the housing. The camera module includes a lens base and a lens barrel. The lens base is mounted on the motherboard. The heating module includes a partition and a heating element. The partition is mounted on top of the lens base, and the heating element is mounted on the partition and electrically connected to the motherboard. The lens barrel is mounted on the lens base and extends through the partition.

[0049] The lens mount is installed on the mainboard, which enables the camera module to be fixed to the mainboard, so that the lens barrel can stably receive the light for imaging; the lens barrel is installed on the lens mount and penetrated by a partition, which can prevent the partition from blocking the lens barrel and thus affecting the imaging range of the camera module, ensuring that the lens barrel is not affected when receiving imaging light.

[0050] The present application also provides an oral scanning device, which includes the host according to any one of the above claims.

[0051] The main unit of the oral scanning device of this application generates radiant energy through a heating module to heat the light-transmitting element, allowing it to maintain a temperature close to that of the oral cavity. When the user uses the oral scanning device to scan the oral cavity, the temperature difference between the light-transmitting element and the oral cavity is small, thus preventing the light-transmitting element from fogging due to cold, ensuring that light can pass through the light-transmitting element and maintaining the imaging quality of the camera module. Furthermore, if the light-transmitting element fogs up, the radiant energy generated by the heating module can increase its temperature, thereby accelerating the evaporation of fog from the surface of the light-transmitting element and improving the defogging speed of the surface of the light-transmitting element.

[0052] In some embodiments, the oral scanning device further includes an opening component, which is connected to the host and surrounds the camera module. The opening component is provided with through holes passing through opposite ends, and the camera module corresponds to the through holes. The end of the opening component away from the host is used to abut against any part of the oral cavity.

[0053] The end of the opening component away from the main unit is spaced apart from the light-transmitting component in the direction of the optical axis, which can prevent the heated light-transmitting component from coming into contact with the user's mouth, thereby avoiding a burning sensation or even scalding to the user.

[0066] See also Figures 1 to 3 The present application provides a host 10 of an oral scanning device 100. The host 10 includes a camera module 11, a shell 12, a heating module 13 and a light-transmitting member 14. The camera module 11 is arranged in the shell 12, and the camera module 11 is used to receive light reflected back from the interior of the oral cavity. The light-transmitting member 14 is arranged in the shell 12, and the light-transmitting member 14 is used to transmit light. The heating module 13 is arranged in the shell 12, and is spaced from the camera module 11 in a direction perpendicular to the optical axis X of the camera module 11 (i.e., the optical axis direction). The heating module 13 and the camera module 11 are both opposite to the light-transmitting member 14 in the optical axis direction. The heating module 13 can generate radiation energy to heat the light-transmitting member 14.

[0067] The oral scanning device 100 is an instrument for detecting the state of the human oral cavity, and includes a main unit 10 and an opening component 30. When in use, the opening component 30 is placed against the human oral cavity, and the main unit 10 obtains internal oral cavity images and / or video information to analyze the user's oral condition.

[0068] Specifically, the shell 12 is a structure for installing other components of the host 10 and accommodating the other components inside the shell 12. The shell 12 can protect the other components. Other components include but are not limited to the heating module 13, the camera module 11, the light-transmitting component 14 and the heat-insulating component 151. The cross-sectional shape of the shell 12 can be, but is not limited to, circular, elliptical, rectangular or other polygons. The cross-sectional shape of the shell 12 of the present application is a runway shape. The material of the shell 12 can be plastic or metal. In the case where the material of the shell 12 is plastic, the shell 12 has good insulation performance, low cost, and light weight. In the case where the material of the shell 12 is metal, the shell 12 has high strength, good wear resistance, and a long service life.

[0069] The camera module 11 is located within the housing 12 and is capable of capturing and receiving light reflected from the interior of the oral cavity. The light is processed by the camera module 11 to form an image or video. The light received by the camera module 11 includes, but is not limited to, natural light, infrared light, and ultraviolet light. The number of camera modules 11 can be one or more (two or more), and is not limited in this application.

[0070] In one example, the camera 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 ultimately forms a two-dimensional image. For example, the camera module 11 can be a two-dimensional infrared camera module. In this case, the heating module 13 is used to emit infrared light. The infrared light emitted by the heating module 13 is irradiated on 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 camera module 11 can be a two-dimensional ultraviolet camera module. In this case, the heating module 13 is used to emit ultraviolet light. The ultraviolet light emitted by the heating module 13 is irradiated on the area to be scanned. The interior of the oral cavity will reflect a portion of the ultraviolet light. The infrared camera module captures the reflected ultraviolet light and converts it into a digital signal. After the digital signal is processed by a computer, an ultraviolet image can be generated.

[0071] In another example, the camera module 11 may be a time-of-flight camera. The time-of-flight camera first emits a laser pulse to illuminate the part to be scanned. The laser pulse reaches the object to be photographed and is reflected back. The time-of-flight camera can calculate the distance from the part to be scanned to the time-of-flight camera by the time the pulse is emitted and the time it is reflected back, thereby forming a three-dimensional image. This application is described as an example in which the camera module 11 is a two-dimensional camera module. In an embodiment in which the camera module 11 is a two-dimensional camera module, the camera module 11 includes a lens base 111 and a lens barrel 113, and the host 10 also includes a main board 17. The lens base 111 of the camera module 11 is mounted on the main board 17 and is electrically connected to the main board 17. The lens barrel 113 is used to guide the reflected light to the image sensor for imaging.

[0072] The light-transmitting member 14 is arranged opposite to the heating module 13, and is also arranged opposite to the camera module 11. The light-transmitting member 14 can be made of materials such as glass, plastic or crystal. The light-transmitting member 14 can serve as a barrier between the external environment and the camera module 11, preventing dust, moisture or other dirt from entering the interior of the housing 12, and protecting the heating module 13 and the camera module 11 from contamination. The light-transmitting member 14 can be one or more. In an embodiment where there are multiple light-transmitting members 14, the properties such as size, shape or transmittance of the multiple light-transmitting members 14 can be different. Furthermore, the light-transmitting member 14 can be coated with coatings with different optical properties, such as coatings that improve light transmittance and reduce stray reflections, such as coatings that filter light of a specific wavelength, such as coatings that prevent fogging, etc.

[0073] The heating module 13 is housed inside the shell 12 and is used to generate radiant energy. The heating module 13 includes but is not limited to electric heating wires, electric heating films, heating sheets or other types of heating elements. The heating module 13 can emit radiant energy to the outside of the shell 12 to heat the light-transmitting member 14 to prevent the light-transmitting member 14 from fogging due to the temperature difference and affecting the imaging of the camera module 11. The heating module 13 can be one or more, and is not limited in this application. It is understandable that the heating module 13 can adjust the heat emitted to adjust the temperature, duration, radiation range and other properties of the heat according to different environments in the oral cavity. The adjustment methods include but are not limited to setting knob adjustment, touch screen adjustment, voice control adjustment, software interface adjustment or automatic adjustment by built-in sensors. In a working environment with relatively low temperature, the heating module 13 can heat the light-transmitting member 14 to remove the fog caused by the light-transmitting member 14 being cold, thereby providing a good imaging environment for the camera module 11.

[0074] The host 10 of the present application generates radiant energy through the heating module 13 to heat the light-transmitting element 14, allowing the light-transmitting element 14 to maintain a temperature close to that of the oral cavity. When the user uses the oral scanning device 100 to scan the oral cavity, the temperature difference between the light-transmitting element 14 and the oral cavity is small, thereby preventing the light-transmitting element 14 from fogging due to cold, ensuring that light can pass through the light-transmitting element 14 and maintaining the imaging quality of the camera module 11. In addition, if the light-transmitting element 14 fogs up, the radiant energy generated by the heating module 13 can increase the temperature of the light-transmitting element 14, thereby accelerating the evaporation rate of the fog on the surface of the light-transmitting element 14 and improving the defogging speed of the surface of the light-transmitting element 14, thus also ensuring the imaging quality of the camera module 11.

[0075] See also Figure 4 In some embodiments, the heating module 13 is spaced apart from the light-transmitting member 14 in the direction of the optical axis.

[0076] Specifically, there is a certain distance between the heating module 13 and the light-transmitting member 14. The heating module 13 uses radiation energy to indirectly heat the light-transmitting member 14, which can make the light-transmitting member 14 heated relatively more evenly and avoid local overheating.

[0077] See also Figure 4 and Figure 5 In some embodiments, a first distance L1 between the heating module 13 and the light-transmitting member 14 in the optical axis direction is greater than or equal to 0.5 mm and less than or equal to 5 mm.

[0078] The first distance L1 can be 0.5mm, 1.5mm, 1.7mm, 1.9mm, 2.5mm, 2.8mm, 3.2mm, 3.5mm, 4.5mm, or 5mm. If the first distance L1 is less than 0.5mm, the radiant energy emitted by the heating module 13 cannot be uniformly distributed, which can easily lead to local overheating of the light-transmitting element 14. If the first distance L1 is greater than 5mm, the distance between the heating module 13 and the light-transmitting element 14 is too far, resulting in a weak heating effect and the radiant energy dissipating.

[0079] The first distance L1 is greater than or equal to 0.5mm, which can ensure that there is a certain distance between the heating module 13 and the light-transmitting member 14. The radiation energy generated by the heating module 13 has a sufficient propagation range to evenly heat the light-transmitting member 14 without causing local overheating. In the embodiment of the present application, the first distance L1 is less than or equal to 5mm, which can reduce the propagation distance of the radiation energy to the light-transmitting member 14, thereby reducing the loss of radiation energy in the air and ensuring the heating efficiency of the heating module 13 on the light-transmitting member 14.

[0080] See also Figure 4 and Figure 5In some embodiments, a first distance L1 between the heating module 13 and the light-transmitting member 14 in the optical axis direction is smaller than a second distance L2 between the camera module 11 and the heating module 13 in a direction perpendicular to the optical axis of the camera module 11 .

[0081] Specifically, L1 is smaller than L2, that is, L1 can be 1 / 2 L2, 1 / 3 L2, 1 / 4 L2, 1 / 5 L2, 1 / 6 L2, 1 / 7 L2, 1 / 8 L2, 1 / 9 L2, or 1 / 10 L2. If L1 is greater than or equal to L2, the heating module 13 is closer to the camera module 11 along the optical axis of the camera module 11. The radiant energy emitted by the heating module 13 is likely to interfere with the operation of the electronic components in the camera module 11, and excessively high temperatures can easily cause deformation of the components in the camera module 11.

[0082] In the embodiment of the present application, L1 is smaller than L2, that is, the heating module 13 is closer to the light-transmitting member 14 in the optical axis direction of the camera module 11, which can reduce the propagation distance of the radiation energy to the light-transmitting member 14, ensure the heating efficiency of the light-transmitting member 14 by the heating module 13, avoid the first distance L1 being large and the radiation energy being lost, and also increase the propagation distance of the radiation energy to the camera module 11, ensuring that there is a certain second distance L2 between the heating module 13 and the camera module 11, and avoiding the radiation energy emitted by the heating module 13 from easily interfering with the operation of the electronic components in the camera module 11.

[0083] See also Figure 3 and Figure 4 In some embodiments, the heating module 13 includes a plurality of heating elements 131 , and the plurality of heating elements 131 are spaced apart and arranged around the periphery of the camera module 11 .

[0084] Specifically, the heating module 13 includes a plurality of heating elements 131, and the heating element 131 may be one or more of a heating wire or a heating film. When the heating module 13 includes one heating element 131, the cross-sectional shape of the one heating element 131 may be a circular ring, an elliptical ring, a triangular ring, a quadrilateral ring or other polygonal ring, etc. When the heating module 13 includes multiple heating elements 131, the shapes of the cross sections of the multiple heating elements 131 may be different. The multiple heating elements 131 may be arranged in a ring, an arc or a matrix to achieve a specific heating effect and coverage area. In an embodiment of the present application, the multiple heating elements 131 are arranged in a ring to surround the periphery of the camera module 11.

[0085] Multiple heating elements 131 surround the periphery of the camera module 11, generating uniform radiant energy that evenly heats the light-transmitting element 14. This prevents uneven surface temperature of the light-transmitting element 14, thereby preventing fogging of the light-transmitting element 14 due to temperature differences and ensuring the imaging quality of the camera module 11. The annular arrangement of the heating elements 131 ensures that the light-transmitting element 14 corresponding to the camera module 11 is effectively and evenly heated, effectively defogging the light-transmitting element 14 while minimizing the impact on the camera module 11.

[0086] See also Figure 3 and Figure 4 In some embodiments, the host 10 further includes a sensor and a processor. The sensor is disposed within the housing 12 and is used to detect environmental data. The processor is disposed within the housing 12 and outputs the degree of fogging of the light-transmitting member 14 based on the environmental data. The heating module 13 generates radiant energy at a heating power and / or heating duration corresponding to the degree of fogging.

[0087] Sensors are used to detect environmental data, including but not limited to the external and internal temperatures of the housing 12, the temperature of the light-transmitting element 14, the external and internal humidity of the housing 12, the humidity of the light-transmitting element 14, and air pressure. Accordingly, sensor types include but are not limited to temperature sensors, humidity sensors, or pressure sensors. There may be one or more sensors, and the sensors may be located either externally or internally of the housing 12. In embodiments where there are multiple sensors, the sensors may be located both externally and internally of the housing 12.

[0088] The processor may be one or more, and is configured to output the degree of fogging of the light-transmitting member 14 based on the environmental data. The heating module 13 generates radiant energy according to the heating power and / or heating duration corresponding to the degree of fogging. For example, in an environment with a lower external temperature, the processor outputs a higher degree of fogging of the light-transmitting member 14, and the heating module 13 generates radiant energy at a higher heating power and / or heating duration.

[0089] The heating module 13 adaptively adjusts the heating power and / or heating time according to the degree of fogging, which can save energy and avoid waste, so that the heating module 13 can adapt to different environments and heat the transparent element 14 more accurately, thereby achieving a better defogging effect on the transparent element 14.

[0090] See also Figure 3 and Figure 4 In some embodiments, the sensor includes a temperature sensor, and the environmental data includes a first temperature inside the housing 12 and a second temperature outside the housing 12 .

[0091] The temperature sensor can obtain temperature data of the environment in which the sensor is located. In one embodiment, the temperature sensor can detect a first temperature inside the shell 12 and a second temperature outside the shell 12. Based on the first temperature and the second temperature, the oral scanning device 100 can obtain temperature difference data between the inside and outside of the shell 12. When the temperature difference data is large, the heating module 13 can be automatically turned on to heat the light-transmitting element 14 to defog the surface of the light-transmitting element 14.

[0092] See also Figure 3 and Figure 4 In some embodiments, the sensor includes a camera module 11 , and the environmental data includes image data captured by the light-transmitting member 14 .

[0093] The camera module 11 can obtain image data of the transparent member 14 . The image data carries the image features of the transparent member 14 . By digitally processing and analyzing the image features, it is possible to determine whether the transparent member 14 is fogged and the degree of fogging.

[0094] See also Figure 4 and Figure 5 In some embodiments, the heating module 13 further includes a partition 133 . The partition 133 is disposed in the housing 12 and separates the housing 12 into a first cavity 1231 and a second cavity 1232 , each of which is isolated from the other. The heating module 13 is accommodated in the first cavity 1231 .

[0095] In the heating module 13, the heating element 131 is mounted on the partition 133 and then electrically connected to the main board 17. That is, the partition 133 can provide a mounting position for the heating element 131, so that the heating element 131 and the partition 133 are connected as a whole, which facilitates the rapid assembly of the heating element 131 on the main board 17. The connection between the heating element 131 and the partition 133 can be a detachable connection or a non-detachable connection, which is not limited in this application.

[0096] The partition 133 can be one or more. In some embodiments, the partition 133 and the housing 12 are integrally structured, that is, the partition 133 and the housing 12 are a single, integrated structure. This enhances the bonding strength between the partition 133 and the housing 12, preventing separation of the partition 133 and the housing 12 during operation of the oral scanning device 100, thereby ensuring the stability and reliability of the operation of the oral scanning device 100. In other embodiments, the partition 133 and the housing 12 are separate structures, that is, the partition 133 and the housing 12 are two different structures. In one example, the partition 133 and the housing 12 can be connected together using a detachable connection method, including but not limited to a snap connection or a threaded connection. In another example, the partition 133 and the housing 12 can be connected together using a non-detachable connection method, including but not limited to bonding or welding.

[0097] The heating module 13 is housed in the first cavity 1231, which allows the radiation energy generated by the heating module 13 to be relatively concentrated in the first cavity 1231, thereby maintaining the concentration of the radiation energy and reducing the loss of radiation energy. In addition, it can also prevent the radiation energy from dissipating into the second cavity 1232, thereby preventing the components in the second cavity 1232 (such as the main board 17 and / or the power supply unit) from being affected by temperature.

[0098] See also Figure 4 and Figure 5 In some embodiments, the host 10 further includes a mainboard 17 and / or a power supply unit (not shown), and the mainboard 17 and / or the power supply unit are accommodated in the second cavity 1232 .

[0099] The mainboard 17 connects and transmits electrical signals between the various components within the main unit 10, ensuring the proper functioning and functionality of the components within the oral scanning device 100. The mainboard 17 controls the operation of components such as the camera module 11 and the heating module 13, processes imaging data, and controls the operation of the main unit 10. The power supply unit can input and output electrical energy. The mainboard 17 and / or the power supply unit are housed in the second cavity 1232 to prevent the radiant energy generated by the heating module 13 from affecting the mainboard 17 and / or the power supply unit.

[0100] See also Figure 3 and Figure 4 In some embodiments, the heating element 131 includes an LED lamp configured to emit light.

[0101] In embodiments where the heating element 131 is an LED lamp, the heating element 131 not only provides radiant energy to heat the light-transmitting element 14 and thereby defog it, but also provides light that illuminates the intraoral area, ensuring high brightness within the imaging range of the camera module 11 and ensuring the imaging quality of the camera module 11. The heating module 13 can emit visible light to the exterior of the housing 12 to illuminate the interior of the oral cavity, or it can emit light of specific wavelengths, such as fluorescent light or ultraviolet light, to accommodate different imaging requirements.

[0102] See also Figure 3 and Figure 4 In some embodiments, the host 10 further includes a heat insulating member 151 . In the optical axis direction of the camera module 11 , the heat insulating member 151 is disposed between the light-transmitting member 14 and the camera module 11 and surrounds the camera module 11 .

[0103] Specifically, the heat insulating member 151 is arranged between the light-transmitting member 14 and the camera module 11, and is used to block the radiation energy emitted by the heating module 13 from entering the camera module 11. The heat insulating member 151 can be one or more. In an embodiment where there are multiple heat insulating members 151, the sizes, shapes and other properties of the multiple heat insulating members 151 can be different. More specifically, part of the radiation energy emitted by the heating module 13 can be radiated to the light-transmitting member 14 to heat the light-transmitting member 14. However, part of the radiation energy will be directly radiated to the camera module 11, causing the camera module 11 to overheat and affect the camera module 11.

[0104] The heat insulation member 151 is arranged between the light-transmitting member 14 and the camera module 11. On the one hand, a part of the radiation energy emitted by the heating module 13 can be radiated to the light-transmitting member 14 to heat the light-transmitting member 14, thereby defogging the light-transmitting member 14; on the other hand, the heat insulation member 151 can block part of the radiation energy emitted by the heating module 13 from being radiated to the camera module 11, ensuring that the components of the camera module 11 will not be affected by the temperature, thereby ensuring the imaging quality of the camera module 11.

[0105] See also Figure 3 and Figure 4 In some embodiments, the thickness of the light-transmitting member 14 is less than 2 mm.

[0106] Specifically, the thickness of the light-transmitting member 14 can be 0.1 mm, 0.3 mm, 0.4 mm, 0.7 mm, 0.9 mm, 1.2 mm, 1.5 mm, 1.7 mm, 1.8 mm, or 2 mm, etc. If the thickness of the light-transmitting member 14 is greater than 2 mm, the weight and cost of the light-transmitting member 14 will increase accordingly, affecting the user experience. In addition, an excessively thick light-transmitting member 14 will require more radiation energy to reach the desired temperature. A thickness of less than 2 mm not only keeps the weight and cost of the light-transmitting member 14 within a reasonable range, but also reduces the radiation energy emitted by the heating module 13, so that the light-transmitting member 14 only requires less radiation energy to reach the desired temperature, saving energy and time.

[0107] See also Figure 3 and Figure 4 In some embodiments, an anti-fog coating is provided on the light-transmitting member 14 .

[0108] Specifically, the light-transmitting member 14 may be provided with an anti-fog coating, the materials of which include, but are not limited to, super-hydrophilic coating, titanium dioxide, and nano-silica lamps. The anti-fog coating may be a single layer or multiple layers. In the embodiment of a multi-layer anti-fog coating, the materials of the anti-fog coating may be different.

[0109] The anti-fog coating can reduce the condensation of water vapor on the surface of the light-transmitting element 14 and prevent the light-transmitting element 14 from fogging, thereby ensuring the light transmittance of the light-transmitting element 14 and improving the imaging quality of the camera module 11 .

[0110] See also Figure 3 and Figure 4 In certain embodiments, the anti-fog coating comprises an anti-fog antimicrobial plastic coating.

[0111] Some anti-fog coatings may maintain their anti-fog effect after being heated, but the performance of the coating may also be degraded due to thermal cycles or temperature changes. For example, some anti-fog coatings still maintain their anti-fog effect after 10 wet-drying cycles (WDC) tests, but a small amount of tiny droplets begin to appear after 20 cycles, indicating that certain components in the coating may be decomposed or changed due to heat. That is, high temperature may accelerate the decomposition or volatilization of certain components in the coating. XPS energy spectrum analysis found that after a certain number of WDC cycles, the sodium alginate (SA) component in the coating almost completely disappeared, which may be related to heat. Durability of the coating: High temperature may affect the durability of the coating. The coating may be damaged under friction or mechanical stress, and high temperature may exacerbate this process.

[0112] The anti-fog coating in the embodiments of this application utilizes an anti-fog antibacterial plastic coating. This anti-fog antibacterial plastic coating maintains its anti-fog effect even after 20 WDC cycles. Furthermore, the anti-fog antibacterial plastic coating has a high visible light transmittance (approximately 89%) and can maintain its transmittance even at high temperatures. The anti-fog antibacterial plastic coating also has antibacterial properties, inhibiting the growth of bacteria on the surface of the anti-fog antibacterial plastic coating, thereby extending its service life.

[0113] In one embodiment, the anti-fog coating is an anti-fog antibacterial plastic coating, and the heating module 13 is an LED lamp. The LED lamp emits light, which simultaneously performs heating and irradiation. The emitted light from the LED lamp has low radiant energy and a slow heating rate, which facilitates uniform heating and reduces damage to the anti-fog coating caused by rapid heating.

[0114] See also Figure 3 and Figure 4 In some embodiments, the housing 12 includes a base 121 and a cover 123. The base 121 defines a loading chamber 123 and a light-transmitting hole 125 communicating with the loading chamber 123. The heating module 13, the camera module 11, and the thermal insulation member 151 are all accommodated within the loading chamber 123. The cover 123 defines a through hole 1231, which is mounted on the base 121. The through hole 1231 communicates with the light-transmitting hole 125. The light-transmitting member 14 is disposed within and covers the through hole 1231.

[0115] Specifically, the loading chamber 123 can accommodate some components of the host 10. The through hole 1231 is correspondingly connected to the light-transmitting hole 125, that is, the through hole 1231 and the light-transmitting hole 125 are aligned in the optical axis direction of the camera module 11, which can ensure that the light emitted by the heating module 13 passes through the through hole 1231 and the light-transmitting hole 125 without being affected. The opening shapes of the through hole 1231 and the light-transmitting hole 125 can be, but are not limited to, circular, elliptical, triangular, quadrilateral or other polygons. It can be understood that the number of the through holes 1231 and the light-transmitting holes 125 is the same. The through hole 1231 can be one or more. The light-transmitting member 14 is arranged in the through hole 1231 and covers the through hole 1231, that is, the light-transmitting member 14 is located in the through hole 1231, and the cover body 123 abuts the light-transmitting member 14 in the circumferential direction R to further fix the light-transmitting member 14.

[0116] See also Figure 3 and Figure 4 In some embodiments, the base 121 includes a first base body 1211 and a second base body 1213 , and the first base body 1211 and the second base body 1213 are detachably connected.

[0117] Specifically, in one division method of the base 121, the base 121 includes a first base body 1211 and a second base body 1213. The first base body 1211 is a structure for mounting other components of the host 10, and these other components are housed within the first base body 1211 to protect them. These other components include, but are not limited to, the heating module 13, the camera module 11, the light-transmitting member 14, and the heat-insulating member 151. The cross-sectional shape of the first base body 1211 can be, but is not limited to, circular, elliptical, rectangular, or other polygonal. In the present application, the cross-sectional shape of the first base body 1211 is a runway shape. The material of the first base body 1211 can be plastic or metal. When the material of the first base body 1211 is plastic, the first base body 1211 has good insulation performance, low cost, and low weight. When the material of the first base body 1211 is metal, the first base body 1211 has high strength, good wear resistance, and a long service life.

[0118] The second base 1213 is used to mount other components of the main unit 10 and house these components within the second base 1213 to protect them. The cross-sectional shape of the second base 1213 is identical to that of the first base 1211, facilitating the connection between the second base 1213 and the first base 1211. The material of the second base 1213 can be the same as or different from that of the first base 1211. The first and second bases 1211 and 1213 are detachably connected, facilitating the maintenance and replacement of each.

[0119] See also Figure 3 and Figure 4 In some embodiments, the base 121 includes a base body 1215 and a boss 1217 , which extends from the base body 1215 . The light-transmitting hole 125 passes through the base body 1215 and the boss 1217 , the cover 123 covers the boss 1217 , and the light-transmitting member 14 is connected to the boss 1217 via an adhesive member 141 .

[0120] Specifically, in another embodiment of the base 121, the base 121 includes a base body 1215 and a boss 1217. In an embodiment of the present application, the boss 1217 extends from the base body 1215, that is, the boss 1217 and the base body 1215 are a single integral structure. This enhances the bonding strength between the boss 1217 and the base body 1215, preventing the boss 1217 and the base body 1215 from separating during operation, thereby ensuring the stability and reliability of the base 121. In other embodiments, the boss 1217 and the base body 1215 are separate structures, that is, the boss 1217 and the base body 1215 are two different structures. In one example, the boss 1217 and the base body 1215 can be connected together using a detachable connection method, including but not limited to a snap connection or a threaded connection. In another example, the boss 1217 and the base body 1215 can be connected together using a non-detachable connection method, including but not limited to bonding or welding. The bonding member 141 includes, but is not limited to, adhesive, tape, clamps, or other mechanical fasteners to further secure the light-transmitting member 14 to the boss 1217. The bonding member 141 also provides a sealing effect, sealing the gap between the light-transmitting member 14 and the boss 1217 to prevent dust, moisture, or other contaminants from entering the gap between the light-transmitting member 14 and the boss 1217.

[0121] Boss 1217 extends from base body 1215. Specifically, boss 1217 protrudes from base body 1215 away from base body 1215, simplifying the alignment process during cover 123 installation. Cover 123 can be directly positioned over boss 1217, facilitating installation. Furthermore, once cover 123 is positioned over boss 1217, boss 1217 limits the movement of cover 123, preventing displacement. Light-transmitting element 14 is supported on boss 1217, providing support and further securing it, preventing displacement due to vibration or impact.

[0122] See also Figure 3 and Figure 4 In some embodiments, within the projection plane in the optical axis direction, the projection of the adhesive member 141 is located on the periphery of the projection of the heating module 13 .

[0123] The projection of the adhesive member 141 is located on the periphery of the projection of the heating module 13, which can reduce the influence of the radiation energy of the heating module 13 on the bonding and prevent the adhesive member 141 from losing its viscosity or deforming due to temperature rise, thereby ensuring a stable connection between the light-transmitting member 14 and the boss 1217.

[0124] See also Figure 3 and Figure 4In some embodiments, the distance between the heating module 13 and the adhesive member 141 is greater than the distance between the heating module 13 and the light-transmitting member 14 in the optical axis direction.

[0125] The short distance between the heating module 13 and the light-transmitting member 14 ensures efficient heating of the light-transmitting member 14 by the heating module 13 and prevents the dissipation of radiant energy due to the long distance between the heating module 13 and the light-transmitting member 14 along the optical axis. The long distance between the heating module 13 and the adhesive member 141 reduces the effect of the radiant energy from the heating module 13 on the adhesive member 141, preventing the adhesive member 141 from losing its adhesiveness or deforming due to temperature rise, thereby ensuring a secure connection between the light-transmitting member 14 and the boss 1217.

[0126] See also Figure 3 and Figure 4 In some embodiments, the base body 1215 is provided with a through-hole 12151, and a fastener 12153 is provided in the base body 1215. The mounting hole 12151 is arranged around the boss 1217. The cover body 123 is provided with a mounting member 1233. The fastener 12153 passes through the mounting hole 12151 and is connected to the mounting member 1233, thereby connecting the cover body 123 to the base 121.

[0127] Specifically, the mounting member 1233, the fastener 12153 and the mounting hole 12151 cooperate to connect the cover 123 to the base 121. In one embodiment, the number of mounting hole 12151 is one, and the corresponding number of fastener 12153 and mounting member 1233 is also one. One mounting hole 12151 can be arbitrarily set on the base body 1215, and the positions of the fastener 12153 and the mounting member 1233 correspond to the position of the mounting member 1233. In this case, the mounting hole 12151, the fastener 12153 and the mounting member 1233 use less material, which can save material and facilitate processing. In another embodiment, the number of mounting holes 12151 can be multiple, and the multiple mounting holes 12151 are evenly or unevenly distributed on the base body 1215, and the positions of the multiple fasteners 12153 and the mounting member 1233 respectively correspond to the positions of the multiple mounting holes 12151. The shape of mounting hole 12151 can be, but is not limited to, a circle, an ellipse, a triangle, a quadrilateral, or other polygon. Preferably, the shape of mounting hole 12151 is the same as the cross-sectional shape of fastener 12153 and mounting member 1233, and the cross-sectional area of mounting hole 12151 is the same as the cross-sectional area of fastener 12153 and mounting member 1233, so that mounting hole 12151 serves to secure and limit the fastener 12153 and mounting member 1233. Thus, through the mating connection of mounting hole 12151, fastener 12153, and mounting member 1233, cover 123 can be secured to base body 1215.

[0128] See also Figure 3 and Figure 4 In some embodiments, the host 10 further includes a sealing member 18 . The sealing member 18 is sleeved on the fastener 12153 and is located between the outer side wall of the fastener 12153 and the inner side wall of the mounting hole 12151 .

[0129] Specifically, the seal 18 can be made of a variety of materials such as rubber, silicone, polypropylene, etc. The seal 18 can be one or more, and is not limited in this application. The seal 18 can be formed separately and then sleeved on the fastener 12153, or it can be sleeved and molded on the outer wall of the fastener 12153 in the form of rubber encapsulation. The seal 18 can seal the gap between the outer wall of the fastener 12153 and the inner wall of the mounting hole 12151, preventing fluid from flowing into the host 10 through the gap, thereby improving the waterproof level of the host 10. In addition, the seal 18 is low in cost and does not take up additional installation volume.

[0130] See also Figure 3 and Figure 4 In some embodiments, the host 10 further includes a mainboard 17 disposed within the housing 12. The camera module 11 includes a lens base 111 and a lens barrel 113. The lens base 111 is mounted on the mainboard 17. The heating module 13 includes a partition 133 and a light source. The partition 133 is mounted on top of the lens base 111. The light source is mounted on the partition 133 and is electrically connected to the mainboard 17. The lens barrel 113 is mounted on the lens base 111 and passes through the partition 133.

[0131] Specifically, the mainboard 17 is used to connect and transmit electrical signals between the various components within the mainframe 10, ensuring the normal operation and functional implementation of the oral scanning device 100. The mainboard 17 can control the operation of components such as the camera module 11 and the heating module 13, process imaging data, and control the operation of the mainframe 10. The lens holder 111 is mounted on the mainframe 17, allowing the camera module 11 to be fixed to the mainframe 17, thereby allowing the lens barrel 113 to stably receive imaging light. The light source is mounted on the partition 133 and then electrically connected to the mainframe 17. Specifically, the partition 133 provides a mounting position for the light source, allowing the light source and partition 133 to be connected as a whole, facilitating rapid assembly of the light source on the mainframe 17. The connection between the light source and the partition 133 can be detachable or non-detachable, and is not limited in this application. The lens barrel 113 is mounted on the lens holder 111 and penetrated by the partition 133 to prevent the partition 133 from blocking the camera imaging range, ensuring that the lens barrel 113 is not affected when receiving imaging light.

[0132] See also Figure 3 and Figure 4 The present application also provides an oral scanning device 100, which includes a host 10 according to any one of the above claims.

[0133] The main unit 10 of the oral scanning device 100 of the present application generates radiant energy through the heating module 13 to heat the light-transmitting element 14, allowing the light-transmitting element 14 to maintain a temperature close to that of the oral cavity. When the user uses the oral scanning device 100 to scan the oral cavity, the temperature difference between the light-transmitting element 14 and the oral cavity is small, thereby preventing the light-transmitting element 14 from fogging due to cold, ensuring that light can pass through the light-transmitting element 14 and maintaining the imaging quality of the camera module 11. In addition, if the light-transmitting element 14 fogs up, the radiant energy generated by the heating module 13 can increase the temperature of the light-transmitting element 14, thereby accelerating the evaporation rate of the fog on the surface of the light-transmitting element 14 and improving the defogging speed of the surface of the light-transmitting element 14.

[0134] See also Figure 3 and Figure 4 In some embodiments, the oral scanning device 100 further includes an opening component 30, which is connected to the host 10 and surrounds the camera module 11. The opening component 30 is provided with through holes passing through opposite ends, and the camera module 11 corresponds to the through holes. The end of the opening component 30 away from the host 10 is used to abut against any part of the oral cavity.

[0135] Specifically, in some embodiments, the opening assembly 30 and the host 10 are integrally structured, that is, the opening assembly 30 and the host 10 form a single, integrated structure. This enhances the bonding strength between the opening assembly 30 and the host 10, preventing separation of the opening assembly 30 and the host 10 during operation of the oral scanning device 100, thereby ensuring the stability and reliability of the operation of the oral scanning device 100. In other embodiments, the opening assembly 30 and the host 10 are separate structures, that is, the opening assembly 30 and the host 10 are two different structures. In one example, the opening assembly 30 and the host 10 can be connected together using a detachable connection method, including but not limited to a snap connection or a threaded connection. In another example, the opening assembly 30 and the host 10 can be connected together using a non-detachable connection method, including but not limited to bonding or welding.

[0136] The opening assembly 30 includes a support member 33 and a deformable member 35. At least a portion of the deformable member 35 is positioned over one end of the support member 33, while the other end of the support member 33 is connected to the main unit 10. The support member 33 maintains the shape of the opening assembly 30, preventing deformation of the opening assembly 30 from obstructing the imaging path of the camera module 11 and affecting the camera's image / video acquisition range. The deformable member 35 is made of a soft rubber material, including but not limited to rubber, silicone, plastic, or synthetic fiber. Examples of rubber materials include but are not limited to natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The support member 33 is made of a hard plastic, metal, or other material. The support member 33 is positioned near the main unit 10 to ensure a stable connection with the main unit 10 and prevent it from rubbing against the mouth during insertion or removal. At least a portion of the deformable member 35 is positioned away from the main unit 10 to ensure a soft contact with the mouth and prevent it from puncturing or scratching the user.

[0137] The opening assembly 30 is used to maintain a certain distance between the camera module 11 and the area to be scanned, preventing the camera module 11 from being too close to the area to be scanned, which could cause out-of-focus issues. The end of the opening assembly 30, which is away from the main body 10, is spaced apart from the light-transmitting member 14 along the optical axis. This prevents the heated light-transmitting member 14 from coming into contact with the user's mouth, potentially causing a burning sensation or even burns.

[0138] Furthermore, when the oral cavity scanning device 100 needs to scan the oral cavity, the end of the opening component 30 facing away from the main unit 10 can be placed against an area inside the user's oral cavity, such as the gums or teeth, to align the scanned area with the camera module 11, allowing the camera module 11 to capture an image of the scanned area. Because the opening component 30 creates a certain distance between the scanned area and the camera module 11, the scanned area falls within the depth of field of the camera module 11, resulting in a clearer image captured by the camera module 11. Other components within the main unit 10 can accurately capture the current oral condition from the captured image, allowing the user to intuitively understand the current oral condition from the captured image, resulting in a more effective scanning effect from the oral cavity scanning device 100.

[0139] When a user scans the oral cavity, the opening assembly 30 of the embodiment of the present application contacts any part of the oral cavity with the end thereof facing away from the main body 10. This allows the camera module 11 to maintain a certain distance from the part to be scanned, and the part to be scanned is within the depth of field of the camera module 11. In this case, when the camera module 11 captures an image of the part to be scanned, the image captured by the camera module 11 is clearer and less likely to be out of focus, allowing the user to accurately understand the current oral condition from the captured image.
