As shown in fig. 1 and 4, the mobile terminal 110 includes a processor 111, a data transceiver 112, an input element 115, and an output element 116, and the server 130 includes a comparator 131, a memory 132, a central processor 133, and a data transceiver 134. The input element 115 includes an image capturing device (such as a camera) 1151, a key 1152, a touch display 1153, and a recording element (not shown), and the output element 116 includes a touch display 1153, a voice output element (which is a speaker, not shown), a vibration motor (not shown), and an LED indicator (not shown). The data transceiver 112 can establish communication connection with the data exchanger 1246 and the data transceiver 134 respectively to transmit data, the data transceiver 112 outputs the received abutment force data after receiving the abutment force data transmitted from the data exchanger 1246, the data transceiver 134 receives the abutment force data transmitted from the data transceiver 112, the comparator 131 is adapted to compare the abutment force with a set value (stored in the memory 132) to obtain a comparison result after the data transceiver 134 receives the abutment force data, and the output element 116 is adapted to output the comparison result for reference by a user after the data transceiver 112 receives the comparison result, so that the user can control the force with which the bristles 123 abut against gums to enable the abutment force to be within the range of the set value. In this embodiment, the setting principle of the setting value is that the pressure intensity of each bristle pressing against the gum is similar to the pressure intensity generated by applying 20-25g force on a blunt end small ball with the diameter of 0.5mm according to the thickness of the bristle when the bristle pressing against the gum.

Therefore, in this embodiment, the pressure sensor 1243 is disposed on the toothbrush 120, the pressure sensor 1243 is used to detect the abutment force received by the brush 123, the comparator 131 compares the abutment force data with the set value to obtain a comparison result after receiving the abutment force data, and the output element 116 outputs the comparison result for the user to refer to, so that the user can detect the own gum through the toothbrush in daily life, and thus the health condition of the own gum can be known in time without going to the hospital.

In this embodiment, the camera 1151 is adapted to take a target picture or a target video from the toothbrush 120 and the oral cavity of the user, and then the mobile terminal 110 or the server 130 processes the target picture or the target video by using an instant localization and mapping technology (SLAM or simultaneous localization AND MAPPING), and obtains the position data or the position change data of the bristles 123 in the oral cavity of the user by capturing the target localization and characteristics. The output element 116 then outputs the position data or the position change data after the mobile terminal 110 obtains the position data or the position change data, so that the user can timely know the position of the bristle 123 in the user's mouth, and thus determine whether the bristle 123 is positioned in the user's mouth correctly. In other embodiments, the program settings may be increased and the comparator 131 or processor 111 load program compares the position data or position change data to a predetermined reference value to cause the output element 116 to prompt when the position data or position change data meets the predetermined reference value.

In this embodiment, the bristles 123 are provided with scale marks in the length direction. In order to make the toothbrush 120 more intelligent, when the user uses the toothbrush 120 to detect the gingival sulcus bleeding index, in order to omit the step of finally judging the health condition of the gum by the user, as an alternative improvement scheme, the image pickup device 1151 may also take a picture of the bristles 123 to obtain a bristle picture or a bristle video, and then the processor 111 or the central processor 133 loads a set program to judge whether the bristle picture or the bristle video has blood or not through an image recognition technology. If present, the blood then the processor 111 or the central processor 133 further identifies the area or depth of coverage of the bristles 123 by the blood in the bristle picture or bristle video (depth refers to the length of the bristles 123 covered by the blood). Finally, the output element 116 outputs the presence data of the blood on the bristles 123.

In the present embodiment, as shown in fig. 3, the motion sensor 1244 includes a gyroscope 1247, a geomagnetic sensor 1248, and an acceleration sensor 1249. The acceleration sensor 1249 is used for detecting linear acceleration data when the toothbrush 120 moves, and the detected linear acceleration data is motion data of the bristles 123 because the bristles 123 are fixed on the toothbrush 120, the geomagnetic sensor 1248 is used for detecting specified direction data of the toothbrush 120, and the detected specified direction data is motion data of the bristles 123 because the bristles 123 are fixed on the toothbrush 120, and the gyroscope 1247 is used for detecting inclination data of the toothbrush 120 or the bristles 123, such as angle data between a brushing surface of the bristles 123 and a horizontal plane.

In this embodiment, the gyroscope 1247 may be used as an angle sensor, and the data exchanger 1246 outputs the inclination data detected by the gyroscope 1247 to the outside after detecting the inclination data of the toothbrush 120 or the brush 123, and the output element 116 outputs the inclination data for reference by the user after receiving the inclination data by the mobile terminal 110. In other embodiments, the comparator 131 or the processor 111 may also be programmed to compare the inclination data with a predetermined angle value (stored in the memory 132), and the output element 116 may indicate when the inclination data satisfies the predetermined angle.

In other embodiments, the comparator 131 or the processor 111 may also compare the specified direction data with the set direction (stored in the memory 132) according to a program setting, and the output element 116 may prompt when the specified direction data satisfies the set direction.

In this embodiment, the microprocessor 1242 may perform a combined analysis on the data detected by the gyroscope 1247, the geomagnetic sensor 1248 and the acceleration sensor 1249 to obtain a pose sensor for detecting the position data or the front-back position change data of the bristles 123 in the user's mouth. The data exchanger 1246 is adapted to output position data or position change data to the outside, and the output element 116 outputs the position data or position change data for reference by the user after the mobile terminal 120 receives the position data or position change data. The front-rear position change data is position change data obtained by detecting the start of the movement of the toothbrush 120 to the end of the movement operation by the position sensor, and for example, the position at which the start of the movement of the toothbrush 120 is detected is referred to as "front" and the position at which the position of the toothbrush 120 is not changed within 2 seconds (the end of the movement is considered as "rear"). In other embodiments, the comparator 131 or the processor 111 may also compare the position data or the position change data with a predetermined reference value (stored in the memory 132) according to a program setting, and the output element 116 prompts when the position data or the position change data satisfies the predetermined reference value. In addition, the execution of the microprocessor 1242 (combined analysis of the data to obtain the pose sensor) in this description may be transferred to be executed by the processor 111 or the central processor 133.

In other embodiments, the pose sensor may also be modified to be composed of a gyroscope 1247 and an acceleration sensor 1249 when the accuracy requirements of the user on the position data or the position change data are not high. At this time, the microprocessor 1242 performs a combination analysis only on the data detected by the gyroscope 1247 and the acceleration sensor 1249 to obtain position data or front-rear position change data of the brush 123 in the user's mouth.

As shown in fig. 2 and 3, the toothbrush 120 in this embodiment is an electric toothbrush, and the pressure sensor 1243 is a pressure detection module. The electric toothbrush includes a motor 126 for driving the brush head 122 to operate, the motor 126 being electrically connected to the PCBA board 124. The pressure detection module is used for detecting load change data of the motor 126, and searching or applying a load change relation curve of the motor 126 under the non-pressed and pressed states of the bristles 123 through the detected load change data, so as to obtain the abutment force applied to the bristles 123. In this embodiment, the data switch 1246 is preferably a bluetooth low energy module or a WIFI module.

In other embodiments, when pressure sensor 1243 is modified to a conventional load cell, it may be preferable to have a fixed mounting on brushhead 122. The comparator 131 and the central processing unit 133 may be integrated together or may be separately provided.

To further illustrate an embodiment of the present invention, a schematic workflow diagram of a system 100 for aiding in the detection of gingival sulcus bleeding index is disclosed, as shown in fig. 5. Specifically, the process comprises the following steps:

In step S107, the data transmission receiver 112 receives the comparison result.

In step S108, the processor 111 (or the central processor 133) processes the target picture or the target video by using the instant localization and mapping technology (SLAM or simultaneous localization AND MAPPING), and obtains the position data or the position change data of the bristles 123 in the oral cavity of the user through the target localization and feature acquisition (if the position data or the position change data is obtained by the server 130, the data sending and receiving unit 134 transmits the position data or the position change data to the mobile terminal 110. In other embodiments, the comparator 131 or the processor 111 may also fit or take an intermediate value with the position data or the position change data obtained in the step S101, and then the output element 116 outputs the adjusted position data or the position change data for reference by the user.

In step S109, the output element 116 outputs the comparison result, the abutment force data, the designated direction data, the inclination data, and the position data or the position change data for reference by the user. The purpose of providing a reference to the user is to facilitate the user to properly control the position and inclination of the bristles 123 in the user's mouth and the force with which the bristles 123 press against the gums when detecting the gingival sulcus bleeding index, so that the bristles 123 are in the proper position, in the proper posture to press the gums, and the abutment force is within the range of the set values.

In step S110, after the toothbrush 120 has inspected the gingival sulcus, the camera 1151 takes a picture of the bristles 123 to obtain a bristle picture or bristle video.

In step S111, the processor 111 loads a setting program, and determines whether blood exists on the bristle picture or bristle video through an image recognition technology. If so, the flow proceeds to step S112, and if not, a blood absence is indicated. In other embodiments, this step may also be performed by server 130.

In step S112, the processor 111 further identifies the area or depth of the bristles 123 covered by blood (refer to the length of the bristles 123 covered by blood) in the bristle picture or bristle video. In other embodiments, this step may also be performed by server 130.

In step S113, the output element 116 outputs the presence data of blood on the bristles 123.

In the present embodiment, as shown in fig. 8, the motion sensor 2244 includes a gyroscope 2247, a geomagnetic sensor 2248, and an acceleration sensor 2249. The acceleration sensor 2249 is used for detecting linear acceleration data when the toothbrush 220 moves, and the detected linear acceleration data is motion data of the toothbrush 223 because the toothbrush 223 is fixed on the toothbrush 220, the geomagnetic sensor 2248 is used for detecting specified direction data of the toothbrush 220, and the detected specified direction data is motion data of the toothbrush 223 because the toothbrush 223 is fixed on the toothbrush 220, and the gyroscope 2247 is used for detecting inclination data of the toothbrush 220 or the toothbrush 223, such as angle data between a brushing surface of the toothbrush 223 and a horizontal plane.

In this embodiment, the gyroscope 2247 may be used as an angle sensor, and the data exchanger 2246 outputs the inclination data detected by the gyroscope 2247 to the outside after detecting the inclination data of the toothbrush 220 or the brush 223, and the output element 216 outputs the inclination data for reference by the user after receiving the inclination data by the mobile terminal 210. In other embodiments, the comparator 231 or the processor 211 may also be programmed to compare the inclination data with a predetermined angle value (stored in the memory 213), and the output element 216 may indicate when the inclination data satisfies the predetermined angle.

In this embodiment, the geomagnetic sensor 2248 is adapted to output the specified direction data to the outside after detecting the specified direction data of the toothbrush 220, and the data exchanger 2246 outputs the specified direction data for reference by the user after the mobile terminal 210 receives the specified direction data. In other embodiments, the comparator 231 or the processor 211 may also compare the specified direction data with the set direction (stored in the memory 213) according to the program settings, and the output element 216 may prompt when the specified direction data satisfies the set direction.

In this embodiment, the microprocessor 2242 may perform a combined analysis on the data detected by the gyroscope 2247, the geomagnetic sensor 2248, and the acceleration sensor 2249 to obtain a pose sensor for detecting the position data or the front-rear position change data of the bristles 223 in the user's mouth. The data exchanger 2246 is adapted to output the position data or the position change data to the outside, and the output element 216 outputs the position data or the position change data for reference by the user after the mobile terminal 210 receives the position data or the position change data. The front-rear position change data is position change data obtained by detecting the start of the movement of the toothbrush 220 to the end of the movement operation by the position sensor, and for example, the position at which the start of the movement of the toothbrush 220 is detected is referred to as "front" and the position at which the position of the toothbrush 220 is not changed within 2 seconds (the end of the movement is considered as "rear"). In other embodiments, the comparator 231 or the processor 211 may also compare the position data or the position change data with a predetermined reference value according to a program setting, and the output element 216 prompts when the position data or the position change data satisfies the predetermined reference value. In addition, the execution content of the microprocessor 2242 (the combined analysis of the data to obtain the pose sensor) in this section of description may be converted to be executed by the processor 211 or the central processor 233.

In other embodiments, the pose sensor may also be modified to be composed of the gyroscope 2247 and the acceleration sensor 2249 when the accuracy requirements of the user on the position data or the position change data are not high. At this time, the microprocessor 2242 performs only a combination analysis of the data detected by the gyroscope 2247 and the acceleration sensor 2249 to obtain position data or front-rear position change data of the brush 223 in the user's mouth.

As shown in fig. 7 and 8, the toothbrush 220 in this embodiment is an electric toothbrush, and the pressure sensor 2243 is a pressure detection module. The electric toothbrush includes a motor 226 that drives the action of the brush head 222, the motor 226 being electrically connected to the PCBA board 224. The pressure detection module is used for detecting load change data of the motor 226, and searching or applying a load change relation curve of the motor 226 in the non-pressed and pressed states of the brush 223 through the detected load change data, so as to obtain the abutting force applied by the brush 223. In this embodiment, the data exchanger 2246 is preferably a bluetooth low energy module or a WIFI module.

In other embodiments, when pressure sensor 2243 is modified to a conventional load cell, it may be preferable to fixedly attach to head 222. In addition, the comparator 231 and the central processing unit 233 may be integrated together or may be separately provided.

To further illustrate an embodiment of the present invention, a schematic workflow diagram of a system 200 for aiding in the detection of gingival sulcus bleeding index is disclosed, as shown in fig. 10. Specifically, the process comprises the following steps:

In step S201, the pressure sensor 2243 detects the abutment force applied to the brush 223, the geomagnetic sensor 2248 detects the data of the specified direction of the toothbrush 220, the angle sensor detects the data of the inclination of the toothbrush 220 or the brush 223, the camera 2151 takes a picture of the toothbrush 220 and the oral cavity of the user to obtain a target picture or a target video, and the pose sensor detects the position data or the front-back position change data of the brush 223 in the mouth of the user.

In step S202, the data exchanger 2246 transmits the abutment force data, the designated direction data, the inclination data, and the position data or the position change data to the outside.

In step S203, the data transceiver 212 receives the abutment force data, the designated direction data, the inclination data, and the position data or the position change data transmitted from the data exchanger 2246.

In step S204, the data transceiver 212 transmits the abutment force data to the outside.

In step S205, the data transceiver 234 receives the abutment force data transmitted from the data transceiver 212.

In step S206, the comparator 231 compares the abutment force with a set value (stored in the memory 232).

In step S207, the counter 235 counts the number of times the abutment force reaches the set value. The data transmitting and receiving unit 234 transmits the counted number of times data to the outside.

In step S208, the data transceiver 212 receives the number of times data output from the data transmission/reception unit 234.

In step S209, the processor 211 (or the central processor 233) processes the target picture or the target video by using the instant localization and mapping technology (SLAM or simultaneous localization AND MAPPING), and obtains the position data or the position change data of the bristles 223 in the oral cavity of the user through the target localization and feature acquisition (if the position data or the position change data is obtained by the server 230, the data sending and receiving unit 234 transmits the position data or the position change data to the mobile terminal 210. In other embodiments, the comparator 231 or the processor 211 may also fit or take an intermediate value with the position data or the position change data obtained in the step S201, and then the output element 216 outputs the adjusted position data or the position change data for reference by the user.

In step S210, the output element 216 outputs the abutment force data, the number of times data, the designated direction data, the inclination data, the position data or the position change data for reference by the user. The purpose of providing a reference to the user is to facilitate the user to quickly know the number of times the abutment force reaches the set value when detecting the gingival crevicular bleeding index, and to correctly control the position and inclination angle of the bristles 223 in the user's mouth and the force with which the bristles 223 press against the gums so that the bristles 223 are in the correct position, the correct posture presses the gums, and the abutment force is within the set value range.

In step S211, after the toothbrush 220 has inspected the gingival sulcus, the imaging device 2151 photographs the bristles 223 to obtain a bristle picture or bristle video.

In step S212, the processor 211 loads a setting program, and determines whether blood exists on the bristle picture or bristle video through the image recognition technology. If so, the flow proceeds to step S213, and if not, a blood absence is presented. In other embodiments, this step may also be performed by server 230.

In step S213, the processor 211 further identifies the area or depth of the bristles 223 covered by blood (refer to the length of the bristles 223 covered by blood) in the bristle picture or bristle video. In other embodiments, this step may also be performed by server 230.

In step S214, the output element 216 outputs the presence data of blood on the bristles 223.
