[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. It should be understood that the specific embodiments described in this section can only be used to explain the present invention and are not used to limit the present invention. Specific embodiment 1

[0047] like Figure 1 As shown, it is a system 100 for assisting in detecting gingival sulcus bleeding index provided by a preferred embodiment of the present invention, which includes a mobile terminal 110, a toothbrush 120 and a server 130. Figure 2 As shown, the toothbrush 120 includes a handle 121 and a brush head 122, and the brush head 122 is provided with bristles 123. A PCBA board 124 and a power supply 125 are also provided inside the toothbrush 120. In this embodiment, the PCBA board 124 and the power supply 125 are packaged into a component by a housing 130 so as to be detachably connected to the toothbrush 120 as a whole.

[0048] like Figure 3 As shown, the PCBA board 124 includes an electrical connection port 1241, a microprocessor 1242, a pressure sensor 1243, a motion sensor 1244 and a data exchanger 1246. Figure 4As shown, the pressure sensor 1243, the motion sensor 1244 and the data exchanger 1246 are electrically connected to the microprocessor 1242 through lines. Among them, the electrical connection port 1241 is used to connect the power supply 125 to power the PCBA board 124; the pressure sensor 1243 is used to detect the abutment force exerted on the bristles 123; the motion sensor 1244 is used to detect the action of the toothbrush 120; the data exchanger 1246 can establish a communication connection with the mobile terminal 110 to transmit data, such as the data exchanger 1246 transmits the abutment force data detected by the pressure sensor 1243 to the outside. Figure 1 , Figure 4 As shown, 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 unit 134. Among them, the input element 115 includes a camera device (such as a camera) 1151, a button 1152, a touch screen 1153 and a recording element (not shown in the figure), and the output element 116 includes a touch screen 1153, a voice output element (a speaker, not shown in the figure), a vibration motor (not shown in the figure) and an LED indicator (not shown in the figure). The data transmitter and receiver 112 can respectively establish communication connections with the data exchanger 1246 and the data transmitter and receiver unit 134 to transmit data. For example, after the data transmitter and receiver 112 receives the abutment force data transmitted by the data exchanger 1246, the data transmitter and receiver 112 outputs the received abutment force data, and the data transmitter and receiver unit 134 receives the abutment force data transmitted by the data transmitter and receiver 112; the comparator 131 is suitable for comparing the abutment force with the set value (stored in the memory 132) to obtain a comparison result after the data transmitter and receiver unit 134 receives the abutment force data; the output element 116 is suitable for outputting the comparison result for the user's reference after the data transmitter and receiver 112 receives the comparison result, so that the user can control the force of the bristles 123 pressing against the gums so that the abutment force is within the set value range. In this embodiment, the setting principle of the set value is based on the thickness of the bristles. When the bristles press against the gums, the pressure exerted on the gums by each bristle pressing against the gums is close to the pressure generated by applying a force of 20-25g on a blunt-headed ball with a diameter of 0.5mm.

[0049] Therefore, in this embodiment, a pressure sensor 1243 is set on the toothbrush 120. The pressure sensor 1243 is used to detect the abutment force exerted on the bristles 123. After receiving the abutment force data, the comparator 131 compares the abutment force data with the set value to obtain a comparison result. Then the output element 116 outputs the comparison result for the user's reference. Therefore, the user can detect his or her gums with the necessary toothbrush in daily life, so that the user can understand the health status of his or her gums in time without going to the hospital.

[0050] In this embodiment, the output form of the comparison result includes direct output of the result or / and output in the form of information prompts. These three output forms can be selected by the user according to their needs. The information prompt is output by the output element 116 when the contact force meets the set value, or when the comparison result meets the preset result. The information prompt is preferably in the form of sound prompt, vibration prompt or light prompt.

[0051] In this embodiment, the camera device 1151 is suitable for photographing the toothbrush 120 and the user's mouth to obtain a target image or a target video, and then the mobile terminal 110 or the server 130 uses the SLAM (simultaneous localization and mapping) technology to process the target image or the target video, and obtains the position data or position change data of the bristles 123 in the user's mouth by locating the target and collecting features. Then, the output element 116 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 know the position of the bristles 123 in the user's mouth in time, thereby judging whether the position of the bristles 123 in the user's mouth is correct. In other embodiments, a program setting can be added, and the comparator 131 or the processor 111 loads a program to compare the position data or the position change data with a predetermined reference value, so that the output element 116 prompts when the position data or the position change data meets the predetermined reference value.

[0052] 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 of the gums, in order to save the user from the final step of judging the health status of the gums, as an improvement scheme that can be selected by the user, the camera device 1151 can also shoot the bristles 123 to obtain a bristle picture or a bristle video, and then the processor 111 or the central processing unit 133 loads the setting program, and determines whether there is blood on the bristle picture or the bristle video through image recognition technology. If there is blood, the processor 111 or the central processing unit 133 further identifies the area or depth of blood coverage of the bristles 123 in the bristle picture or the bristle video (depth refers to the length of the bristles 123 covered by blood). Finally, the output element 116 outputs the data on the presence of blood on the bristles 123.

[0053] In this embodiment, if Figure 3As shown, the motion sensor 1244 includes a gyroscope 1247, a geomagnetic sensor 1248 and an acceleration sensor 1249. The acceleration sensor 1249 is used to detect linear acceleration data when the toothbrush 120 moves. Since the bristles 123 are fixed on the toothbrush 120, the detected linear acceleration data is the motion data of the bristles 123; the geomagnetic sensor 1248 is used to detect the specified direction data of the toothbrush 120. Since the bristles 123 are fixed on the toothbrush 120, the detected specified direction data is the motion data of the bristles 123; the gyroscope 1247 is used to detect the inclination data of the toothbrush 120 or the bristles 123, for example, to detect the angle data between the brushing surface of the bristles 123 and the horizontal plane.

[0054] In this embodiment, the gyroscope 1247 can be used as an angle sensor. After detecting the inclination data of the toothbrush 120 or the bristles 123, the data exchanger 1246 outputs the inclination data detected by the gyroscope 1247; after the mobile terminal 110 receives the inclination data, the output element 116 outputs the inclination data for user reference. In other embodiments, the comparator 131 or the processor 111 can also compare the inclination data with a predetermined angle value (stored in the memory 132) according to program settings, and the output element 116 prompts when the inclination data meets the predetermined angle.

[0055] In this embodiment, after the geomagnetic sensor 1248 detects the designated direction data of the toothbrush 120, the data exchanger 1246 is adapted to output the designated direction data externally; after the mobile terminal 110 receives the designated direction data, the output element 116 outputs the designated direction data for user reference. In other embodiments, the comparator 131 or the processor 111 can also compare the designated direction data with the set direction (stored in the memory 132) according to the program setting, and the output element 116 gives a prompt when the designated direction data meets the set direction.

[0056] In this embodiment, the microprocessor 1242 can combine and analyze the data detected by the gyroscope 1247, the geomagnetic sensor 1248 and the acceleration sensor 1249 to obtain a posture sensor for detecting the position data or the front-to-back position change data of the bristles 123 in the user's mouth. The data exchanger 1246 is suitable for outputting the position data or the position change data to the outside; after the mobile terminal 120 receives the position data or the position change data, the output element 116 outputs the position data or the position change data for the user's reference. Among them, the front-to-back position change data refers to the position change data of the posture sensor from the detection of the toothbrush 120 starting to move to the end of the moving action, for example, the position when the toothbrush 120 starts to move is detected as "front", and the position when the toothbrush 120 position does not change within 2 seconds (it is considered that the movement is over) is "back". In other embodiments, the comparator 131 or the processor 111 can also compare the position data or the position change data with a predetermined reference value (stored in the memory 132) according to the program setting, and the output element 116 prompts when the position data or the position change data meets the predetermined reference value. In addition, the execution content of the microprocessor 1242 in this description (combining and analyzing the data to obtain the posture sensor) can be transferred to be executed by the processor 111 or the central processing unit 133.

[0057] In other embodiments, when the user does not have high requirements for the accuracy of the position data or position change data, the posture sensor can also be changed to consist of a gyroscope 1247 and an acceleration sensor 1249. In this case, the microprocessor 1242 only performs a combined analysis on the data detected by the gyroscope 1247 and the acceleration sensor 1249 to obtain the position data or the front-to-back position change data of the bristles 123 in the user's mouth.

[0058] like Figure 2 , Figure 3 As shown, 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 that drives the brush head 122 to move, and the motor 126 is electrically connected to the PCBA board 124. The pressure detection module is used to detect the load change data of the motor 126, and the load change relationship curve of the motor 126 when the bristles 123 are not pressed and pressed is searched or applied through the detected load change data, so as to obtain the contact force on the bristles 123. In this embodiment, the data exchanger 1246 is preferably a low-power Bluetooth module or a WIFI module.

[0059] In other embodiments, when the pressure sensor 1243 is changed to a common pressure measuring element, it may be preferred to be fixedly arranged on the brush head 122. The comparator 131 and the central processor 133 may be integrated together or separately arranged.

[0060] To further explain the embodiments of the present invention, Figure 5 As shown, it discloses a schematic diagram of the workflow of a system 100 for assisting in detecting gingival sulcus bleeding index. Specifically, the process includes the following steps:

[0061] In step S101, the pressure sensor 1243 detects the abutting force exerted on the bristles 123; the geomagnetic sensor 1248 detects the designated direction data of the toothbrush 120; the angle sensor detects the inclination data of the toothbrush 120 or the bristles 123; the camera device 1151 photographs the toothbrush 120 and the user's mouth to obtain a target image or a target video; the posture sensor detects the position data of the bristles 123 in the user's mouth or the front-to-back position change data.

[0062] In step S102 , the data exchanger 1246 transmits the contact force data, the designated direction data, the inclination data, and the position data or the position change data to the outside.

[0063] In step S103 , the data transceiver 112 receives the contact force data, the designated direction data, the inclination data, and the position data or the position change data transmitted from the data exchanger 1246 .

[0064] In step S104 , the data transmitter and receiver 112 transmits the contact force data to the outside.

[0065] In step S105 , the data transceiver unit 134 receives the contact force data transmitted by the data transceiver 112 .

[0066] In step S106, the comparator 131 compares the contact force with the set value (stored in the memory 132) to obtain a comparison result. The data sending and receiving unit 134 transmits the comparison result to the outside.

[0067] Step S107: the data transceiver 112 receives the comparison result.

[0068] In step S108, the processor 111 (or the central processor 133) processes the target image or target video using the SLAM (simultaneous localization and mapping) technology, and obtains the position data or position change data of the bristles 123 in the user's mouth by locating the target and collecting its features (if obtained by the server 130, the data sending and receiving unit 134 transmits the position data or position change data to the mobile terminal 110). In other embodiments, the comparator 131 or the processor 111 can also perform data fitting or take the intermediate value of the position data or position change data obtained in this step with the position data or position change data detected by the posture sensor in step S101 to obtain the adjusted position data or position change data; then the output element 116 outputs the adjusted position data or position change data for the user's reference.

[0069] Step S109, the output element 116 outputs the comparison result, the contact force data, the specified direction data, the inclination data, and the position data or the position change data for the user's reference. The purpose of providing the user with a reference is to facilitate the user to correctly control the position, inclination angle and the force of the bristles 123 pressing the gums in the user's mouth when detecting the gingival sulcus bleeding index, so that the bristles 123 are in the correct position, the correct posture presses the gums, and the contact force is within the set value range.

[0070] Step S110, after the toothbrush 120 has checked the gingival sulcus, the camera device 1151 takes a picture of the bristles 123 to obtain a bristle picture or a bristle video.

[0071] In step S111, the processor 111 loads a setting program and uses image recognition technology to determine whether there is blood on the bristle picture or bristle video. If there is blood, the process proceeds to step S112. If not, a prompt is given that there is no blood. In other embodiments, this step may also be performed by the server 130.

[0072] In step S112 , the processor 111 further identifies the area or depth (referring to the length of the bristles 123 covered by blood) of the bristles 123 in the bristle picture or bristle video. In other embodiments, this step may also be performed by the server 130 .

[0073] In step S113 , the output element 116 outputs the data of the presence of blood on the bristles 123 .

[0074] The above step description is only for further explaining the embodiment of the present invention. When executing each step, there is no time sequence and the order of the steps can be interchanged. Specific embodiment 2

For example, after the data transmitter and receiver 212 receives the abutment force data transmitted by the data exchanger 2246, the data transmitter and receiver 212 outputs the received abutment force data, and the data transmitter and receiver unit 234 receives the abutment force data transmitted by the data transmitter and receiver 212; the comparator 231 is suitable for comparing the abutment force with the set value (stored in the memory 232) after the data transmitter and receiver unit 234 receives the abutment force data; the counter 235 is used to count the number of times the abutment force reaches the set value; the output element 216 is suitable for outputting the abutment force or / and the number of times for user reference or prompting when the number of times reaches the set number after the mobile terminal 210 receives the abutment force or / and the number of times. The information prompt is preferably in the form of sound prompt, vibration prompt or light prompt. In this embodiment, the setting principle of the set value is that when the bristles are pressed against the gums, the pressure exerted on the gums by each bristle pressing against the gums is close to the pressure generated by applying a force of 20-25g on a blunt-headed ball with a diameter of 0.5mm. In other embodiments, a timer can also be set in the mobile terminal 210 and / or the toothbrush 220, and the timer is used to count the time when the contact force reaches the set value, and the output element 215 is suitable for outputting the time data or giving a prompt when the time reaches the set time (such as 10 seconds).

[0078] Therefore, in this embodiment, a pressure sensor 2243 is provided on the toothbrush 220, and the pressure sensor 2243 is used to detect the abutment force exerted on the bristles 223; the comparator 231 is suitable for comparing the abutment force with the set value; the counter 235 is used to count the number of times the abutment force reaches the set value; so the user can control the force of the bristles 223 pressing against the gums by outputting the abutment force through the output element 216, so that the abutment force is within the range of the set value. At the same time, the user can quickly know the number of times the abutment force reaches the set value according to the number of times the output element 216 outputs. Therefore, the user can detect his gums with the necessary toothbrush in daily life, so that he can know the health status of his gums in time without going to the hospital.

[0079] In this embodiment, the camera device 2151 is suitable for photographing the toothbrush 220 and the user's mouth to obtain a target image or a target video, and then the mobile terminal 210 or the server 230 uses the SLAM or simultaneous localization and mapping technology to process the target image or the target video, and obtains the position data or the front and back position change data of the bristles 223 in the user's mouth by locating the target and collecting features. Then the output element 216 outputs the position data or the position change data so that the user can know the position of the bristles 223 in the user's mouth in time, so as to determine whether the position of the bristles 223 in the user's mouth is correct. In other embodiments, a program setting can be added, and the comparator 131 or the processor 211 loads a program to compare the position data or the position change data with a predetermined reference value, so that the output element 216 prompts when the position data or the position change data meets the predetermined reference value.

[0080] In this embodiment, the bristles 223 are provided with scale marks in the length direction. In order to make the toothbrush 220 more intelligent, when the user uses the toothbrush 220 to detect the gingival sulcus bleeding index of the gums, in order to save the user from the final step of judging the health status of the gums, as an improvement scheme that can be selected by the user, the camera device 2151 can also shoot the bristles 223 to obtain a bristle picture or a bristle video, and then the processor 211 or the central processing unit 233 loads the setting program, and determines whether there is blood on the bristle picture or the bristle video through image recognition technology. If there is blood, the processor 211 or the central processing unit 233 further identifies the area covered by blood or the depth of coverage (depth refers to the length of the bristles 223 covered by blood) of the bristles 223 in the bristle picture or the bristle video. Finally, the output element 216 outputs the data on the presence of blood on the bristles 223.

[0081] In this embodiment, if Figure 8 As shown, the motion sensor 2244 includes a gyroscope 2247, a geomagnetic sensor 2248 and an acceleration sensor 2249. The acceleration sensor 2249 is used to detect linear acceleration data when the toothbrush 220 moves. Since the bristles 223 are fixed on the toothbrush 220, the detected linear acceleration data is the motion data of the bristles 223; the geomagnetic sensor 2248 is used to detect the specified direction data of the toothbrush 220. Since the bristles 223 are fixed on the toothbrush 220, the detected specified direction data is the motion data of the bristles 223; the gyroscope 2247 is used to detect the inclination data of the toothbrush 220 or the bristles 223, for example, to detect the angle data between the brushing surface of the bristles 223 and the horizontal plane.

[0082] In this embodiment, the gyroscope 2247 can be used as an angle sensor. After detecting the inclination data of the toothbrush 220 or the bristles 223, the data exchanger 2246 outputs the inclination data detected by the gyroscope 2247; after the mobile terminal 210 receives the inclination data, the output element 216 outputs the inclination data for user reference. In other embodiments, the comparator 231 or the processor 211 can also compare the inclination data with a predetermined angle value (stored in the memory 213) according to program settings, and the output element 216 prompts when the inclination data meets the predetermined angle.

[0083] In this embodiment, after the geomagnetic sensor 2248 detects the designated direction data of the toothbrush 220, the data exchanger 2246 is adapted to output the designated direction data externally; after the mobile terminal 210 receives the designated direction data, the output element 216 outputs the designated direction data for user reference. In other embodiments, the comparator 231 or the processor 211 can also compare the designated direction data with the set direction (stored in the memory 213) according to the program setting, and the output element 216 gives a prompt when the designated direction data meets the set direction.

[0084] In this embodiment, the microprocessor 2242 can combine and analyze the data detected by the gyroscope 2247, the geomagnetic sensor 2248 and the acceleration sensor 2249 to obtain a posture sensor for detecting the position data or the front-to-back position change data of the bristles 223 in the user's mouth. The data exchanger 2246 is suitable for outputting the position data or the position change data to the outside; after the mobile terminal 210 receives the position data or the position change data, the output element 216 outputs the position data or the position change data for the user's reference. Among them, the front-to-back position change data refers to the position change data of the posture sensor from the detection of the toothbrush 220 starting to move to the end of the moving action, for example, the position when the toothbrush 220 starts to move is detected as "front", and the position when the toothbrush 220 position does not change within 2 seconds (it is considered that the movement is completed) is "back". In other embodiments, the comparator 231 or the processor 211 can also compare the position data or the position change data with the predetermined reference value according to the program setting, and the output element 216 prompts when the position data or the position change data meets the predetermined reference value. In addition, the execution content of the microprocessor 2242 in this paragraph description (combining and analyzing the data to obtain the posture sensor) can be converted to be executed by the processor 211 or the central processing unit 233.

[0085] In other embodiments, when the user does not have high requirements for the accuracy of the position data or position change data, the posture sensor can also be changed to consist of a gyroscope 2247 and an acceleration sensor 2249. In this case, the microprocessor 2242 only performs a combined analysis on the data detected by the gyroscope 2247 and the acceleration sensor 2249 to obtain the position data or the front-to-back position change data of the bristles 223 in the user's mouth.

[0086] like Figure 7 , Figure 8 As shown, 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 brush head 222 to move, and the motor 226 is electrically connected to the PCBA board 224. The pressure detection module is used to detect the load change data of the motor 226, and the load change relationship curve of the motor 226 when the bristles 223 are not pressed and pressed is searched or applied through the detected load change data, so as to obtain the contact force on the bristles 223. In this embodiment, the data exchanger 2246 is preferably a low-power Bluetooth module or a WIFI module.

[0087] In other embodiments, when the pressure sensor 2243 is changed to a common pressure measuring element, it may be preferred to be fixedly arranged on the brush head 222. In addition, the comparator 231 and the central processor 233 may be integrated together or separately arranged.

[0088] To further explain the embodiments of the present invention, Fig.10 As shown, it discloses a schematic diagram of the workflow of a system 200 for assisting in detecting gingival sulcus bleeding index. Specifically, the process includes the following steps:

[0089] In step S201, the pressure sensor 2243 detects the abutting force exerted on the bristles 223; the geomagnetic sensor 2248 detects the designated direction data of the toothbrush 220; the angle sensor detects the inclination data of the toothbrush 220 or the bristles 223; the camera device 2151 photographs the toothbrush 220 and the user's mouth to obtain a target image or a target video; the posture sensor detects the position data of the bristles 223 in the user's mouth or the front-to-back position change data.

[0090] In step S202 , the data exchanger 2246 transmits the contact force data, the designated direction data, the inclination data, and the position data or the position change data to the outside.

[0091] In step S203 , the data transceiver 212 receives the contact force data, the designated direction data, the inclination data, and the position data or the position change data transmitted from the data exchanger 2246 .

[0092] In step S204, the data transmitter and receiver 212 transmits the contact force data to the outside.

[0093] In step S205 , the data transceiver unit 234 receives the contact force data transmitted by the data transceiver 212 .

[0094] In step S206 , the comparator 231 compares the contact force with a set value (stored in the memory 232 ).

[0095] Step S207, the counter 235 counts the number of times the contact force reaches the set value, and the data sending and receiving unit 234 transmits the counted number of times to the outside.

[0096] In step S208 , the data transceiver 212 receives the number of times data output by the data transceiver unit 234 .

[0097] In step S209, the processor 211 (or the central processor 233) processes the target image or target video using the SLAM (simultaneous localization and mapping) technology, and obtains the position data or position change data of the bristles 223 in the user's mouth by locating the target and collecting its features (if obtained by the server 230, the data sending and receiving unit 234 transmits the position data or position change data to the mobile terminal 210). In other embodiments, the comparator 231 or the processor 211 can also perform data fitting or take the intermediate value of the position data or position change data obtained in this step with the position data or position change data detected by the posture sensor in step S201 to obtain the adjusted position data or position change data; then the output element 216 outputs the adjusted position data or position change data for the user's reference.

[0098] Step S210, the output element 216 outputs the abutment force data, the number of times data, the specified direction data, the inclination data, the position data or the position change data for the user's reference. The purpose of providing the user with a reference is to facilitate the user to quickly know the number of times the abutment force reaches the set value when detecting the gingival sulcus bleeding index, and to correctly control the position, inclination angle and the force of the bristles 223 pressing the gums in the user's mouth, 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.

[0099] Step S211, after the toothbrush 220 has checked the gingival sulcus, the camera device 2151 takes a picture of the bristles 223 to obtain a bristle picture or a bristle video.

[0100] In step S212, the processor 211 loads the setting program and determines whether there is blood on the bristle picture or bristle video by image recognition technology. If there is blood, the process proceeds to step S213. If not, a prompt is given that there is no blood. In other embodiments, this step can also be performed by the server 230.

[0101] In step S213 , the processor 211 further identifies the area or depth (referring to the length of the bristles 223 covered by blood) of the bristles 223 in the bristle picture or bristle video. In other embodiments, this step may also be performed by the server 230 .

[0102] In step S214 , the output element 216 outputs the data of the presence of blood on the bristles 223 .

[0103] The above step description is only for further explaining the embodiment of the present invention. When executing each step, there is no time sequence and the order of the steps can be interchanged.
