[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the following further details the present application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] The following will combine with the specific implementation manners to detail an oral intelligent analysis toothbrush provided by an embodiment of the present application. Figure 1 Schematic diagram of the module structure of an oral intelligent analysis toothbrush provided by an embodiment of the present application, as Figure 1 shown, the toothbrush includes a toothbrush body 110, hollow bristles 210, an oral cavity detection device 310 and an interaction device 410. The oral cavity detection device 310 includes a detection liquid storage cavity 3101, a detection liquid reaction area 3102, a micro diversion module 3103, a color development induction device 3104 and an oral cavity analysis module 3105. Among them,

[0037] The hollow bristles 210 are internally provided with a first one-way valve 2101 and a saliva channel 2102 for allowing saliva in the user's oral cavity to flow in one-way.

[0038] The detection liquid storage cavity 3101 is internally provided with a second one-way valve 31011 and is connected to the saliva channel 2102 for squeezing the detection liquid stored in the detection liquid storage cavity 3101 into the saliva channel 2102 to mix the detection liquid with saliva.

[0039] The detection liquid reaction area 3102 is used to hold the mixture of the detection liquid and saliva and undergo a color development reaction.

[0040] The micro diversion module 3103 is used to divert the mixture of the detection liquid and saliva to the detection liquid reaction area 3102.

[0041] The color development induction device 3104 is arranged in the detection liquid reaction area 3102 and is used to collect the optical signals generated by the color development reaction of the mixture of the detection liquid and saliva in the detection liquid reaction area 3102.

[0042] The oral cavity analysis module 3105 is used to receive and process the optical signals output by the color development induction device 3104 and generate the oral health monitoring results.

[0043] The interaction device 410 is used to send the oral health monitoring results to the user.

[0044] In implementation, Figure 2 This is a schematic diagram of the external structure of an example of an oral intelligent analysis toothbrush provided by an embodiment of the present application. As Figure 2 shown, the hollow bristles 210 are of a hollow structure. When the user brushes their teeth, saliva can enter the inside of the toothbrush through the hollow bristles 210. Figure 3 This is a schematic diagram of the internal structure of an example of an oral intelligent analysis toothbrush provided by an embodiment of the present application. As Figure 3As shown, taking a hollow bristle as an example, the first one-way valve 2101 inside the hollow bristle 210 and the hollow saliva channel 2102 can be utilized to ensure that the saliva in the user's oral cavity enters the saliva channel 2102 during the brushing process. The first one-way valve 2101 only allows liquid to enter unidirectionally, preventing backflow and external contamination. For example, when the user is brushing their teeth, saliva naturally flows into the inside of the hollow bristle 210 and enters the saliva channel 2102 through the first one-way valve 2101, eliminating the need for the user to manually collect saliva for detection and simplifying the sampling process. The second one-way valve 31011 in the detection liquid storage cavity 3101 can control the release of the detection liquid, and the detection liquid can be squeezed or released in other ways to be mixed with the saliva sample. For example, during the brushing process, as saliva flows into the detection liquid storage cavity 3101 built into the toothbrush, the second one-way valve 31011 opens, and the detection liquid is squeezed and thoroughly mixed with the saliva. The detection liquid is a non-toxic chemical reagent specifically used to detect specific bacteria and viruses in the oral cavity, such as Streptococcus mutans, Porphyromonas gingivalis, and the HPV virus in the oral cavity. After the detection liquid is mixed with the saliva, specific bacteria or viruses can trigger a color reaction. The micro diversion module 3103 can be a control chip used to stably control the flow direction and speed of the mixture, ensuring that the mixture reacts evenly within the detection liquid reaction area 3102 and providing stable conditions for the subsequent color reaction. The color reaction sensing device 3104 is arranged inside the detection liquid reaction area 3102 and can be an optical sensor that can real-time monitor the color change inside the detection liquid reaction area 3102 and convert it into an optical signal. The color reaction sensing device 3104 can accurately capture the minute differences in color change during the reaction process. The detection liquid can consist of multiple color-developing reagents, which can undergo color reactions when coming into contact with different bacteria and viruses in the oral cavity. For example, tetrazolium salts (such as TTC) can react with bacterial metabolites to show different colors for the color reaction sensing device to detect and transmit the signal to the oral analysis module 3105. The oral analysis module 3105 can be an AI system that can analyze the components in the saliva, such as the concentration of bacteria, viruses, or other oral health indicators, based on the collected optical signals using a pre-established machine learning model. It can also compare with historical data to judge the current oral health status and generate detailed oral health monitoring results, which can include information such as bacterial concentration and dental health risks. The interaction device 410 can transmit the oral health monitoring results to the user through a display screen, sound, or Bluetooth synchronization function, facilitating the user to view their oral health status and providing feedback and suggestions. For example, a display screen can be integrated into the toothbrush, which can display real-time health feedback, such as a prompt for high bacterial concentration. The user can also synchronize the report through a mobile phone App to view the health suggestions given by the toothbrush to help the user improve oral hygiene.The toothbrush according to the embodiment of the present application can not only complete the daily oral cleaning function, but also automatically monitor oral health through the built-in oral detection device, provide instant and convenient health feedback, and help users better maintain oral health.

[0045] As an alternative embodiment, the hollow bristles 210 are made of a polymer material.

[0046] In practice, the polymer material has the advantages of being lightweight, corrosion-resistant, wear-resistant and chemically stable, and can maintain the integrity of the hollow structure during long-term use, ensuring that the functions of the saliva channel and the one-way valve are not lost. In addition, the flexibility and mature forming process of the polymer material make it possible to manufacture the hollow structure and precisely control the internal channel size, thereby ensuring the smooth mixing and transmission of the detection liquid and saliva. For example: in the manufacturing process, polypropylene (PP) or polyethylene (PE) can be selected as the raw material, and the hollow bristles 210 are produced by injection molding or extrusion molding processes. During injection molding, the mold is pre-designed with a structure having an internal saliva channel 2102 and a first one-way valve 2101 to ensure that the manufactured hollow bristles 210 are both light and strong. The hollow bristles 210 can effectively guide the unidirectional inflow of saliva in the oral cavity during brushing, and at the same time resist chemical erosion after long-term contact with the detection liquid, thereby ensuring the reliability and long-term stability of the overall detection system.

[0047] As an alternative embodiment, the first one-way valve 2101 can be provided at the end of the hollow bristles 210 to define the flow direction of saliva in the saliva channel 2102.

[0048] In practice, the design of the first one-way valve 2101 is based on the principle of allowing only unidirectional fluid passage. Its function is to limit the flow of saliva in the saliva channel 2102 to only one direction, preventing the saliva from flowing back or flowing backward inside the toothbrush bristles, and ensuring that the collected saliva sample is not contaminated. For example: during the production process, a groove structure suitable for installing the valve can be machined at the end of the hollow bristles 210 through a precision mold, and then the first one-way valve 2101 made of rubber or flexible polymer is installed in the groove by using hot pressing or injection molding processes. When brushing teeth, when the saliva in the user's oral cavity enters the saliva channel 2102 of the hollow bristles 210, the one-way valve automatically opens to allow the saliva to flow in smoothly. When the pressure is reversed, the valve closes to prevent the saliva from flowing backward, ensuring the stability of the mixing process of the detection liquid and saliva, thereby improving the accuracy and reliability of the entire detection system.

[0049] As an alternative embodiment, the detection liquid storage chamber 3101 is detachably connected to the toothbrush body 110.

[0050] In implementation, the detection liquid storage cavity 3101 can be replaced regularly, which can be similar to the replacement method of the brush head of an electric toothbrush. Each detection liquid storage cavity 3101 can be used multiple times, facilitating the daily maintenance of users.

[0051] As an alternative implementation, the oral cavity detection device 310 further includes an oral cavity imaging module 3106, which is configured to collect user oral cavity images and generate an oral cavity model.

[0052] The oral cavity analysis module 3105 is further configured to generate an oral cavity health detection result according to the oral cavity model and the optical signal output by the color sensing device 3104.

[0053] In implementation, the oral cavity imaging module 3106 can continuously collect images of various angles inside the oral cavity when the user is brushing their teeth, and then use an integrated image processing unit or algorithm to stitch these images into a complete three-dimensional oral cavity model to reflect information such as tooth arrangement and gum condition. The oral cavity analysis module 3105 can evaluate health indicators (such as dental plaque and gum inflammation) inside the oral cavity through the joint processing of the optical signal and the three-dimensional oral cavity model, and adopt a preset algorithm model to achieve a more refined detection of the oral cavity health status. For example, the oral cavity analysis module 3105 is built-in with dedicated software, which first performs a quantitative analysis of the color value and concentration of the signal from the color sensing device 3104, and then combines the model data provided by the oral cavity imaging module 3106 to perform a comparative analysis of the tooth surface condition, gum contour, etc. Finally, a detailed oral cavity health report is generated and displayed to the user in real time through the interaction device, thereby helping the user obtain more comprehensive health assessment information.

[0054] As an alternative implementation, as Figure 1 shown, the oral cavity imaging module 3106 includes a 3D scanning camera 31061 and an image stitching sub-module 31062. Among them,

[0055] The 3D scanning camera 31061 uses structured light or time-of-flight technology to dynamically capture user oral cavity images during the process of the user brushing their teeth.

[0056] The image stitching sub-module 31062 is configured to generate an oral cavity model according to the user oral cavity images through a preset image stitching algorithm.

[0057] In implementation, the 3D scanning camera 31061 can use a micro CMOS image sensor, and can be as Figure 2As shown, it is installed on the brush head or can also be installed on the side of the toothbrush handle close to the brush head to facilitate capturing three-dimensional images of teeth during the brushing process. Structured light or Time-of-Flight (ToF) technology can be used. When using structured light, the 3D scanning camera 31061 can project a predefined grating into the user's oral cavity, and obtain depth information by capturing the deformation of the grating on the surface of objects in the oral cavity. When using Time-of-Flight technology, the distance between various parts in the oral cavity and the camera can be calculated by measuring the time required for the light pulse to travel from emission to return. For example, during the user's brushing process, the 3D scanning camera 31061 is activated and projects structured light into the oral cavity in real time. The camera captures the light distortion caused by the surface morphology of the teeth and gums, or measures the time difference of the returned light pulse, obtaining a series of image data containing depth information. The image stitching sub-module 31062 can process the multi-angle images captured from the 3D scanning camera 31061 using a preset image stitching algorithm. This algorithm synthesizes a complete three-dimensional model of the oral cavity by extracting feature points in the images, performing image registration and fusion. For example, after receiving the continuously captured image data, the image stitching sub-module 31062 can use algorithms such as SIFT or SURF to extract the key features of each frame of the image, and then match and align these images. After registration, the module fuses multiple frames of images to generate a three-dimensional model reflecting the internal structure of the user's oral cavity, clearly showing information such as tooth arrangement and gum contour, providing accurate structural data for subsequent health detection. In addition, the user can intuitively view their oral cavity model, understand the oral condition in real time, increasing the entertainment and enthusiasm of the user's brushing.

[0058] As an alternative embodiment, the toothbrush further includes:

[0059] A disinfection device (not shown in the figure) for disinfecting the hollow bristles 210 and the oral cavity detection device 310.

[0060] In practice, the toothbrush integrates a disinfection device. After each use, the user can activate the disinfection mode of the disinfection device to disinfect the hollow bristles 210 and the oral cavity detection device 310 to ensure the safety of the next use.

[0061] As an alternative embodiment, the disinfection device can be a UV-C ultraviolet disinfection lamp.

[0062] As an alternative embodiment, the interaction device 410 can include a display screen 4101 and a data synchronization module 4102 (not shown in the figure). Among them,

[0063] The display screen 4101 is used to display the oral health detection results to the user.

[0064] The data synchronization module is used to synchronize data with the user's mobile terminal.

[0065] In implementation, the display screen 4101 can convert the oral health detection results generated by the oral analysis module 3105 into intuitive image or text information for the user to understand the detection data in real time. For example, the display screen can be integrated at the front end of the toothbrush. After the oral analysis module 3105 processes the signals collected by the color sensing device, the detection results (such as health scores, color change indications, etc.) are immediately displayed on the screen in the form of numbers, graphics or text, and the user can directly read the oral health status without additional equipment. The data synchronization module can implement data transmission with the user's mobile terminal based on wireless communication technologies (such as Bluetooth, Wi-Fi or NFC) to ensure that the detection data can be remotely stored and further analyzed. For example, the data synchronization module is automatically activated after the detection is completed, communicates with the user's paired smartphone through Bluetooth Low Energy connection, and transmits the oral health detection results to the mobile phone App. This App not only stores the historical detection data, but also generates trend charts and health reports, and reminds the user of regular detections or attention to oral health status through push notifications. The user can share the oral health detection results output by the toothbrush with the dentist for remote consultation.

[0066] As an alternative implementation, if there are oral health detection results, the toothbrush can also give further suggestions through the interaction device 410, such as "It is recommended to seek medical treatment as soon as possible" or "It is recommended to increase the brushing frequency".

[0067] As an alternative implementation, the toothbrush has a waterproof and moisture-proof structural design.

[0068] In implementation, the toothbrush can have good waterproof and moisture-proof performance (such as IPX7 rating) to ensure that the electronic components are not damaged by water during daily brushing and cleaning.

[0069] As an alternative implementation, the toothbrush can be made of lightweight and durable materials to ensure a comfortable grip. At the same time, its internal electronic components are optimized to keep the overall weight as low as possible.

[0070] As an alternative implementation, the embodiments of the present application also provide a method for feeding back the user's tooth health condition based on the data detected by the toothbrush and intelligently recommending the matters needing attention for the user to brush teeth according to the user's historical data, as follows:

[0071] 1. Modeling of user historical data: The toothbrush can record the user's historical health data through the cloud, including the changes in the color of saliva (such as: yellow, red, green), and the results of each 3D tooth scan (including the presence of dental caries, cracks, gingivitis).

[0072] 2. AI Health Trend Analysis: It can compare the user's current test results with historical data to judge the oral health trend. If dental caries are detected in the latest 3D scan, it will prompt the user "The problem of dental caries may be getting worse and needs attention". If the saliva color continuously appears yellow, it will prompt the user "There may be a problem of tooth demineralization". Otherwise, it is considered that "The dental health condition is good".

[0073] 3. Saliva and Reagent Reaction Analysis: According to the combination of different reagent types (such as bacterial reagents, viral reagents) and saliva colors, potential dental diseases are analyzed. For example: If the saliva is red and combined with bacterial reagents, it can prompt the user "Gingivitis or gum bleeding". If the saliva is green, it can prompt "There is Streptococcus mutans in the oral cavity". Blue is related to viral infections.

[0074] 4. 3D Scan Analysis: It can identify common problems based on the scan data. For example, if dental caries are detected, it will prompt "There are dental caries". If cracks are detected, it will prompt "There are cracks in the teeth and may need repair". If gingivitis is detected, it will prompt "There are gum problems". If there is no abnormality, it will prompt "The teeth are healthy".

[0075] 5. Comprehensive Diagnosis and Personalized Recommendations: Combining saliva analysis, 3D scan results and AI trend analysis, the system outputs the existing health problems, the current oral health trend, and targeted brushing and care recommendations. For example, if there is gingivitis: It is recommended to use anti-inflammatory oral products and have regular check-ups. If there are dental caries: It is recommended to treat them as soon as possible. If there are cracks: It is recommended to repair them. If it is related to a virus: It is recommended to have further examinations and consult a doctor. If there are no obvious problems: It is recommended to continue to maintain good oral hygiene habits.

[0076] The embodiments of the present application provide an intelligent oral analysis toothbrush. The technical solutions provided by the embodiments of the present application have at least the following beneficial effects: The toothbrush includes a toothbrush body, hollow bristles, an oral detection device, and an interaction device. The oral detection device includes a detection liquid storage cavity, a detection liquid reaction area, a micro flow guiding module, a color development induction device, and an oral analysis module. Among them, the hollow bristles are internally provided with a saliva channel and a first one-way valve, which are used to allow the saliva in the user's oral cavity to flow in one-way.

The detection liquid reaction area is used to accommodate the mixture of the detection liquid and the saliva and undergo a color development reaction. The micro flow guiding module is used to guide the mixture to the detection liquid reaction area. The color development induction device is used to collect the optical signals generated by the color development reaction in the detection liquid reaction area. The oral analysis module is used to receive and process the optical signals output by the color development induction device and generate an oral health monitoring result. The interaction device is used to send the oral health monitoring result to the user. The technical solution of the present application integrates the toothbrush body, hollow bristles, an oral detection device, and an interaction device, realizing automatic collection of saliva and oral health detection during daily brushing. Specifically, the hollow bristles are internally provided with a saliva channel and a first one-way valve, enabling the saliva in the user's oral cavity to flow in only one direction, thus achieving continuous and automatic sampling. The detection liquid storage cavity is provided with a second one-way valve and is connected to the saliva channel, which can accurately squeeze the detection liquid into the channel during brushing to fully mix with the saliva. The mixture is guided by the micro flow guiding module to the detection liquid reaction area, where a color development reaction occurs. Subsequently, the color development induction device collects the optical signals generated by the reaction, and the oral analysis module processes them to generate an oral health monitoring result, which is finally fed back to the user through the interaction device. The embodiments of the present application provide a multifunctional toothbrush that combines daily brushing, 3D scanning, and bacterial and viral detection, which can help users understand their oral health status in real time while maintaining oral cleanliness. By non-invasively collecting saliva samples during the brushing process for analysis, it is more convenient than sampling in the hospital and is suitable for daily household use. By automatically analyzing the data, it helps users understand the situation of bacteria and viruses, predict oral health risks, and reduce the possibility of oral diseases. It is applicable to scenario applications, such as daily household oral health detection: Through the toothbrush, users can regularly understand whether there are potential health problems in the oral cavity, such as excessive bacteria, gingivitis, etc. Another example is the oral health management of children and the elderly: It helps monitor the oral conditions of children and the elderly groups with higher oral health requirements and reduces the risks of dental caries and oral lesions. Record and share oral health data through a mobile phone App, establish a remote medical relationship with dentists, and facilitate doctors' diagnosis and advice.
