[0049] As people pay more and more attention to oral problems, oral care devices are becoming more and more popular among consumers. In order to further enhance the care function of oral care devices, an energy receiving module is usually provided on the oral care device. The oral care device provided with the energy receiving module can facilitate users to observe and clean the oral cavity more comprehensively. However, in the related art, the energy receiving module in the oral care device is prone to damage during the assembly process. In order to improve this problem, the embodiment of the present application provides an oral care device 100 ( Figure 1 shown).

[0050] See also Figure 1 and Figure 2The oral care device 100 of the embodiment of the present application includes a handle 10, a movement 30, a care piece 50 and an energy receiving module 70. The handle 10 includes a handle shell 11 and a cover plate 13. The handle shell 11 is provided with a through hole 111, and the cover plate 13 covers the through hole 111. The movement 30 is installed in the handle shell 11 and partially extends out of the handle shell 11. The care piece 50 is installed on the part of the movement 30 that extends from the handle shell 11. The energy receiving module 70 is arranged in the handle shell 11 through the through hole 111 and is electrically connected to the movement 30. The energy receiving module 70 corresponds to the cover plate 13. The energy receiving module 70 is used to receive energy reflected back at least partially by the care piece 50 and / or human features outside the oral cavity.

[0051] Specifically, the oral care device 100 is a structure for detecting and cleaning the oral cavity, and the oral care device 100 includes a toothbrush, an endoscope, an oral irrigator, and an oral scanner. In the case where the oral care device 100 is a toothbrush, the oral care device 100 may be an electric toothbrush. An electric toothbrush is a device that uses a high-speed vibration movement to drive the brush head to vibrate to achieve the effect of cleaning teeth. In this case, the care piece 50 of the oral care device 100 is a brush head. In the case where the oral care device 100 is an endoscope, the endoscope is inserted into the oral cavity to detect the oral health status. For example, the endoscope can detect problems such as oral ulcers, wisdom tooth inflammation, dentition defects or residual roots and crowns of teeth. In this case, the care piece 50 of the oral care device 100 is a detector inserted into the oral cavity. In the case where the oral care device 100 is an oral irrigator, the oral irrigator can clean teeth and tooth gaps by means of pulsed water flow impact. In this case, the care piece of the oral care device 100 is a nozzle inserted into the oral cavity. When the oral care device 100 is an oral scanner, the oral scanner can scan and detect information such as teeth, gums, and oral mucosa in the oral cavity. In this case, the care part of the oral care device 100 is a scanning head that extends into the oral cavity. This application takes the oral care device 100 as an electric toothbrush as an example for explanation.

[0052] The handle 10 of the oral care device 100 is a structure for the user to hold. Functional modules such as a control area 19 and a display area may be provided on the surface of the handle 10 to facilitate the user to operate and use various functions of the oral care device 100. The handle 10 is generally a cylindrical structure to make the user's grip feel more comfortable. The handle 10 may also have an anti-slip structure to prevent the oral care device 100 from slipping off the hand during use.

[0053] The handle shell 11 is a structure for the user to hold, and the handle shell 11 is also used to load other components, such as loading the movement 30 and the energy receiving module 70 and other structures. The material of the handle shell 11 may be plastic or rubber, etc. The handle 10 made of plastic or rubber material is light in weight and easy to pick up and put. The through hole 111 is a spatial structure for the energy receiving module 70 to enter through the through hole 111 and be installed in the handle shell 11. The opening shape of the through hole 111 may be, but is not limited to, circular, elliptical, triangular or quadrilateral, etc. The opening area of ​​the through hole 111 is at least larger than the cross-sectional area of ​​the energy receiving module 70.

[0054] The cover plate 13 is a structure used to protect the energy receiving module 70 together with the handle shell 11. The cover plate 13 is detachably connected to the handle shell 11, wherein the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. In one embodiment, after the energy receiving module 70 is loaded into the handle shell 11 through the through hole 111 and electrically connected to the movement 30, the cover plate 13 is connected to the handle shell 11. In another embodiment, the energy receiving module 70 may be connected to the cover plate 13 first, and then the energy receiving module 70 and the cover plate 13 are connected to the handle shell 11 together. The material of the cover plate 13 may be plastic or rubber, etc. The material of the cover plate 13 may be the same as or different from the material of the handle shell 11.

[0055] See also Figure 2 In the case where the oral care device 100 is an electric toothbrush, the care component 50 is a brush head. The movement 30 is a structure for driving the brush head to vibrate. When the oral care device 100 is started, the movement 30 is powered to drive the brush head connected to the movement 30 to vibrate, so that the vibrating brush head can clean the teeth. The frequency at which the movement 30 drives the brush head to vibrate can be, but is not limited to, 2000 times per minute, 4000 times per minute, or 8000 times per minute.

[0056] See also Figure 1 and Figure 2In the case where the oral care device 100 is an electric toothbrush, the care part 50 is a brush head. The brush head is a structure used to clean teeth by vibration. During the process of brushing teeth, the brush head can instantly decompose the toothpaste into foam through high-frequency vibration, and can deeply clean the tooth surface and the gaps between teeth to achieve a better cleaning effect. The brush head includes a brush rod 51 and bristles 53 connected to each other. The brush rod 51 is installed on the part of the movement 30 extending from the handle shell 11, and the bristles 53 are arranged on the brush rod 51. The brush rod 51 is a structure used to connect the movement 30 and the bristles 53. The brush rod 51 is used to transmit vibration to the bristles 53, so that the bristles 53 can effectively clean the teeth during the vibration process. The material of the brush rod 51 can be but not limited to plastic or rubber. The bristles 53 are a structure that is in direct contact with the teeth, and the bristles 53 are used to clean the teeth. The material of the bristles 53 can be but not limited to nylon, rubber or pig bristles. Preferably, the bristles 53 may have good toughness and elasticity, so as to better clean the teeth and the gaps between teeth.

[0057] Please continue reading Figure 1 and Figure 2 , the energy receiving module 70 is used to receive at least part of the energy reflected back from the care piece 50 and / or the human features outside the oral cavity, and obtain relevant information based on the reflected energy analysis. In one embodiment, the energy receiving module 70 can only receive at least part of the energy reflected from the care piece 50, and at this time, only the care piece 50 is within the receiving range of the energy receiving module 70. The energy receiving module 70 can identify and analyze the features and related parameters of the care piece 50 to obtain the image information of the care piece 50 and the component information of the care piece 50 (such as model, production time and service life, etc.). In another embodiment, the energy receiving module 70 can only receive at least part of the energy reflected from the human features outside the oral cavity (such as the facial features of the human body), and at this time, the receiving range of the energy receiving module 70 is completely staggered with the care piece 50, that is, there is no care piece 50 within the receiving range of the energy receiving module 70. The energy receiving module 70 can identify and analyze the human features outside the oral cavity, and obtain relevant information generated by the user when using the oral care device 100, such as the use time, use frequency and the identity of the user. In another embodiment, the energy receiving module 70 can also simultaneously receive at least part of the energy reflected by the care piece 50 and / or the human features outside the oral cavity. At this time, the care piece 50 and the human features outside the oral cavity are both located within the receiving range of the energy receiving module 70. The energy receiving module 70 can obtain the image information or distance and position information of the care piece 50 and the human features outside the oral cavity based on the energy reflected by the two, and determine the positional relationship between the care piece 50 and the human features outside the oral cavity at this time. For example: in which predetermined tooth area the care piece 50 is located, whether the care piece 50 is in a predetermined working position, and the operating time of the care piece 50 in a predetermined tooth area.

[0058] The energy receiving module 70 of the present application is used to take images of the care parts 50 and / or human features outside the oral cavity, and obtain relevant information based on image analysis. In one embodiment, the energy receiving module 70 is used to take images of the care parts 50. The care parts 50 are usually provided with image codes, and the energy receiving module 70 can obtain the model information of the care parts 50 by taking the image code. Through the model information of the care parts 50, it can be analyzed whether the care parts 50 are compatible with the handle 10. In addition, the energy receiving module 70 can obtain the tooth area position corresponding to the current care parts 50 by taking images of the care parts 50, so as to know the operation time of the care parts 50 in each tooth area and other information. For example, when the energy receiving module 70 captures that the care parts 50 stay in the same tooth area for less than 2 minutes, the oral care device 100 can issue a prompt to the user. In another embodiment, the energy receiving module 70 can be used to take images of human features outside the oral cavity. When the user is brushing his teeth, the energy receiving module 70 captures an image of the human features outside the oral cavity, and analyzes the tooth area corresponding to the care component 50 at this moment through the image of the human features outside the oral cavity, thereby obtaining information such as the operation time of the care component 50 in the corresponding tooth area. In one embodiment, the energy receiving module 70 can be used to capture an image of the care component 50, and the energy receiving module 70 can also be used to capture an image of the human features outside the oral cavity. The energy receiving module 70 uses the captured images to analyze and obtain more accurate data.

[0059] The energy receiving module 70 can be, but is not limited to, a camera, a time-of-flight camera, or an infrared camera. In one example, the energy receiving module 70 is a camera. The lens of the camera collects light within the viewing angle (light from the care piece 50 and / or the human features outside the oral cavity) and transmits the light to the image sensor, which converts the light signal into an electrical signal and finally forms an image after a series of conversions. In another example, the energy receiving module 70 is a time-of-flight camera. The time-of-flight camera first emits a laser pulse to illuminate the object being photographed (the care piece 50 and / or the human features outside the oral cavity), and the laser pulse reaches the object being photographed and is reflected back. The time-of-flight camera can calculate the distance from the object being photographed to the time-of-flight camera by the time the pulse is emitted and the time it is reflected back, so that a three-dimensional image can be formed. In another example, the energy receiving module 70 is an infrared camera. The infrared camera emits infrared rays to illuminate the object being photographed (the care piece 50 and / or the human features outside the oral cavity), and the object being photographed will reflect a portion of the infrared rays. The infrared camera captures the reflected infrared light and converts it into digital signals. After the digital signals are processed by a computer, an infrared image can be generated.

[0060] The oral care device 100 of the embodiment of the present application is provided with a through hole 111 and a cover plate 13 on the handle shell 11. During the assembly process, the movement 30 can be assembled first, and then the energy receiving module 70 and the cover plate 13 can be installed on the handle shell 11 through the through hole 111. The energy receiving module 70 of the embodiment of the present application is not easily damaged during the assembly process.

[0061] The oral care device 100 is further described below with reference to the accompanying drawings.

[0062] See also Figure 2 and Figure 3 In some embodiments, the central axis of the energy receiving module 70 is parallel to the central axis of the movement 30. The central axis of the energy receiving module 70 refers to: a straight line that divides the handle shell into symmetrical parts. The central axis of the movement 30 refers to: a straight line that divides the handle shell into symmetrical parts. The central axis of the energy receiving module 70 is the main optical axis of the energy receiving module 70. The viewing angle range α of the energy receiving module 70 can be, but is not limited to, 45°, 50° or 60°, etc. When the central axis of the energy receiving module 70 is parallel to the central axis of the movement 30, the care component 50 can be within the viewing angle range of the energy receiving module 70, so that during the brushing process, the energy receiving module 70 can capture images of the care component 50 and / or human features outside the oral cavity, and judge the position of the tooth area currently being brushed based on the position of the care component 50 and / or human features outside the oral cavity, thereby obtaining the operating time of the care component 50 in each tooth area.

[0063] In other embodiments, the central axis of the energy receiving module 70 intersects with the central axis of the movement 30 at the care piece 50. At this time, the main optical axis (central axis) of the energy receiving module 70 can be aligned with the bristles 53 of the care piece 50, so that the energy receiving module 70 can obtain a large amount of image information on both sides of the care piece 50. For example, during the process of brushing teeth, the energy receiving module 70 can capture more information in the oral cavity and / or on the face, so that more and more accurate information can be obtained from the image.

[0064] See also Figure 3In some embodiments, along the direction of the handle 10 pointing to the care piece 50, the distance L between the energy receiving module 70 and the side of the cover plate 13 close to the care piece 50 is not greater than 5mm. Specifically, the maximum distance L between the energy receiving module 70 and the side of the cover plate 13 close to the care piece 50 is not greater than 5mm. The handle 10 is provided with an installation space 17, and the installation space 17 is used for the energy receiving module 70 to be installed therein. When the maximum distance L between the energy receiving module 70 and the second part 135 of the cover plate 13 is greater than 5mm, the distance between the energy receiving module 70 and the care piece 50 is far away. Since the viewing angle range of the energy receiving module 70 is a conical range, when the energy receiving module 70 is far away from the care piece 50, the non-energy transmission area of ​​the handle 10 will block part of the field of view of the energy receiving module 70, thereby causing the energy receiving module 70 to be unable to completely capture the image of the care piece 50, and the shooting effect of the energy receiving module 70 is poor. And at this time, the volume of the installation space 17 of the handle 10 is large, and the overall aesthetics of the oral care device 100 is poor. When the maximum distance L between the energy receiving module 70 and the second portion 135 of the cover plate 13 is not greater than 5 mm (less than or equal to 5 mm), the handle 10 does not block the field of view of the energy receiving module 70, and the care component 50 can be completely within the field of view of the energy receiving module 70. The energy receiving module can better capture the image of the care component 50, and the energy receiving module 70 has a better shooting effect. In this case, the volume of the installation space 17 of the handle 10 is small, and the overall aesthetics of the oral care device 100 is better.

[0065] See also Figure 2 In some embodiments, the oral care device further includes an energy emitting module for emitting energy, and an energy receiving module 70 for receiving at least part of the energy emitted by the energy emitting module and reflected by the care component 50 and / or human features outside the oral cavity.

[0066] In the case where the energy receiving module 70 is a time-of-flight camera, the energy transmitting module is the laser transmitting end of the time-of-flight camera, and the energy receiving module 70 is the receiving end of the time-of-flight camera. After the laser is emitted from the energy transmitting module and irradiates the care piece 50 and / or the human features outside the oral cavity, the laser is reflected back by the care piece 50 and / or the human features outside the oral cavity, and the reflected laser is received by the energy receiving module 70. In the case where the energy receiving module 70 is an infrared camera, the energy transmitting module is the infrared light transmitting end of the infrared camera, and the energy receiving module 70 is the receiving end of the infrared camera. After the infrared light is emitted from the energy transmitting module and irradiates the care piece 50 and / or the human features outside the oral cavity, the infrared light is reflected back by the care piece 50 and / or the human features outside the oral cavity, and the reflected infrared light is received by the energy receiving module 70.

[0067] See also Figure 3 and Figure 4 Furthermore, in some embodiments, the handle 10 also includes a partition 15, which is arranged at the through hole 111 and forms an installation space 17 together with the cover plate 13, the energy receiving module 70 is installed on the partition 15 and / or the cover plate 13 and is located in the installation space 17, and the movement 30 is arranged outside the installation space 17.

[0068] The partition 15 is a structure used to form an installation space 17 together with the cover plate 13. The partition 15 and the handle shell 11 can be an integral structure or a split structure. In the case where the partition 15 and the handle shell 11 are an integral structure, the partition 15 and the handle shell 11 can be integrally formed. In the case where the partition 15 and the handle shell 11 are a split structure, the partition 15 can be detachably or non-detachably installed on the handle shell 11. The detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0069] In one embodiment, the energy receiving module 70 is first installed on the partition 15, and then the cover plate 13 is connected to the partition 15, so that the cover plate 13 and the partition 15 can jointly protect the energy receiving module 70. In another embodiment, the energy receiving module 70 is first installed on the cover plate 13, and then the cover plate 13 and the energy receiving module 70 are jointly connected to the partition 15, so that the cover plate 13 and the partition 15 can jointly protect the energy receiving module 70.

[0070] The installation space 17 formed by the partition 15 and the cover plate 13 is a sealed space. The energy receiving module 70 is installed in the installation space 17, which can prevent external water vapor from entering the installation space 17 to affect the shooting quality of the energy receiving module 70. And during the operation of the oral care device 100, the care component 50 will be subjected to pressure. The pressure of the care component 50 is transmitted to the movement 30, so that the movement 30 will move in the handle shell 11. The energy receiving module 70 may be squeezed during the movement of the movement 30, which may cause the energy receiving module 70 to shift or even be damaged. The energy receiving module 70 is isolated from the movement 30 by setting the partition 15, so that the movement 30 will not interfere with the energy receiving module 70 during operation.

[0071] See also Figure 5 In some embodiments, a light strip 151 is provided on the partition 15, and a portion of the cover plate 13 corresponding to the light strip 151 is light-transmissive. Different states of the light strip 151 may correspond to different working states of the energy receiving module 70. By observing the state of the light strip 151, the user can intuitively know the working state of the energy receiving module 70 at the moment, and the user's experience is good. In addition, the light strip 151 can also enhance the aesthetics of the oral care device 100.

[0072] In one embodiment, the light strip 151 can emit light of different colors when powered on, and the light of different colors can correspond to different working states of the energy receiving module 70. For example, when the energy receiving module 70 starts working (shooting), the light strip 151 can emit green light. When the energy receiving module 70 works abnormally (is damaged), the light strip 151 can emit red light. When the energy receiving module 70 is not working, the light strip 151 can emit yellow light or no light. The user can observe the different colors of the light strip 151 through the light-transmitting portion on the cover plate 13, thereby knowing the working state of the energy receiving module 70 at the moment.

[0073] In another embodiment, the light strip 151 may have different flashing frequencies after being powered on, and the different flashing frequencies of the light strip 151 may correspond to different working states of the energy receiving module 70. For example, when the energy receiving module 70 starts working (shooting), the flashing frequency of the light strip 151 is faster (for example, 10 times / min). When the energy receiving module 70 works abnormally (is damaged), the flashing frequency of the light strip 151 is very fast (for example, 30 times / min). When the energy receiving module 70 is not working, the light strip 151 is in a normally bright or normally dark state. The user can observe the different flashing frequencies of the light strip 151 through the light-transmitting portion on the cover plate 13, thereby knowing the working state of the energy receiving module 70 at this moment.

[0074] See also Figure 5 In some embodiments, the portion of the cover plate 13 corresponding to the light strip 151 is annular. Among them, the annular portion 139 on the cover plate 13 is light-transmissive, and the annular portion 139 is the light-transmissive portion. The material of the annular portion 139 can be, but is not limited to, glass, plexiglass, acrylic or a light-transmissive film, so that the user can see the luminous state of the light strip 151 through the annular portion 139. At this time, the light strip 151 can be a strip, annular or other shapes. Preferably, the light strip 151 is also an annular structure, and the annular light strip 151 corresponds to the annular portion 139 of the cover plate 13, so that the user can see the annular light. The annular light can enhance the aesthetics of the oral care device 100, and the user's experience is better.

[0075] Please continue reading Figure 5, further, in some embodiments, the partition 15 is a hollowed-out annular structure, and the energy receiving module 70 corresponds to the non-hollowed-out area of ​​the partition 15. At this time, an installation space 17 is formed between the non-hollowed-out area of ​​the partition 15 and the cover plate 13, the energy receiving module 70 is located in the installation space 17, and the movement 30 is located outside the installation space 17. In the case where the partition 15 is a hollowed-out annular structure, the electrical connection between the energy receiving module 70 and the movement 30 is relatively simple. The energy receiving module 70 and the movement 30 are electrically connected through an electrical connector, and the electrical connector can be passed through the hollowed-out area of ​​the partition 15 to electrically connect the energy receiving module 70 and the movement 30. And at this time, the weight of the partition 15 is relatively light, so the weight of the oral care device 100 is relatively light, which is convenient for the user to take and put, and the oral care device 100 that the user takes and puts has a good feel. At this time, the material used for the partition 15 is less, which can save materials.

[0076] See also Figure 2 and Figure 3 Furthermore, in some embodiments, the partition 15 protrudes in a direction close to the central axis of the handle shell 11 compared to the inner side of the handle shell 11. In the case where the partition 15 protrudes in a direction close to the central axis of the handle shell 11, the provision of the partition 15 can make full use of the internal space of the handle shell 11 to prevent the cover plate 13 from protruding too much relative to the outer side wall of the handle shell 11 after the energy receiving module 70 is installed between the partition 15 and the cover plate 13. In this case, the oral care device 100 has a better aesthetic appearance.

[0077] See also Figure 5 In some embodiments, when the energy receiving module 70 is installed on the partition 15, a limiting member 153 is provided on the partition 15, and the limiting member 153 is used to limit the circumferential and / or axial direction of the energy receiving module 70.

[0078] Specifically, during the operation of the oral care device 100, vibrations will be generated. If there is no limiter 153 to limit the energy receiving module 70, the energy receiving module 70 will move relative to the partition 15, which will cause shaking in the image captured by the energy receiving module 70. In addition, the energy receiving module 70 is prone to collision during movement, which may cause damage to the energy receiving module 70.

[0079] The limiter 153 is a structure for limiting the position of the energy receiving module 70. The limiter 153 is integrally formed with the partition 15, or the limiter 153 is detachably or non-detachably installed on the side of the partition 15 close to the cover plate 13. In one embodiment, the limiter 153 limits the circumferential direction of the energy receiving module 70. At this time, the energy receiving module 70 will not move circumferentially relative to the partition 15, that is, the energy receiving module 70 will not move in a plane perpendicular to the central axis of the energy receiving module 70. In another embodiment, the limiter 153 limits the axial direction of the energy receiving module 70. At this time, the energy receiving module 70 will not move axially relative to the partition 15, that is, the energy receiving module 70 will not move up and down along the central axis of the energy receiving module 70. In another embodiment, the limiter 153 limits both the circumferential and axial directions of the energy receiving module 70. At this time, the energy receiving module 70 will not move in a plane perpendicular to the central axis of the energy receiving module 70, and the energy receiving module 70 will not move up and down along the central axis of the energy receiving module 70. The position limiting member 153 has a good effect of limiting the position of the energy receiving module 70.

[0080] See also Figures 3 to 5 In some embodiments, the partition 15 is provided with a through hole 155, and the movement 30 includes a driving member 31 and a first circuit board 33 located in the handle shell 11. The output shaft 311 of the driving member 31 partially extends out of the handle shell 11, and the brush rod 51 is connected to the output shaft 311. The first circuit board 33 is arranged on one side of the driving member 31, and the energy receiving module 70 is electrically connected to the first circuit board 33 through the first conductive member 34 penetrating the through hole 155.

[0081] Specifically, the output shaft 311 is used to connect the driving member 31 and the brush rod 51, and the output shaft 311 is used to transmit the power of the driving member 31 to the brush rod 51, so as to vibrate the brush rod 51. When the brush rod 51 vibrates, the bristles 53 can effectively clean the teeth.

[0082] The first circuit board 33 is disposed on one side of the driving member 31 close to the partition 15. The first circuit board 33 is an adapter board, and the first circuit board 33 is used to electrically connect the energy receiving module 70 and the second circuit board 35 (main control board) of the movement 30. The first circuit board 33 is electrically connected to the energy receiving module 70 through the first conductive member 34, and the first circuit board 33 is electrically connected to the second circuit board 35, so that the energy receiving module 70 and the second circuit board 35 (main control board) of the movement 30 are electrically connected.

[0083] The first conductive member 34 electrically connects the energy receiving module 70 and the first circuit board 33 to enable conduction between the energy receiving module 70 and the first circuit board 33. The first conductive member 34 may be, but is not limited to, a wire, a flexible circuit board, solder or a pin, etc. This application is described by taking the first conductive member 34 as a wire as an example. The wire is passed through the through hole 155 to electrically connect the energy receiving module 70 and the first circuit board 33. When the energy receiving module 70 is installed on the partition 15, the distance between the energy receiving module 70 and the first circuit board 33 is relatively close. At this time, the wire can be shorter, which can save the material of the wire.

[0084] The non-hollow area of ​​the partition 15 is provided with a perforation 155, which is a space structure for the first conductive member 34 to pass through. The opening shape of the perforation 155 can be, but is not limited to, a circle, an ellipse, a triangle or a quadrilateral. The opening area of ​​the perforation 155 is greater than or equal to the cross-sectional area of ​​the first conductive member 34. The first conductive member 34 is provided with the perforation 155 to connect the energy receiving module 70 and the first circuit board 33. The setting of the perforation 155 facilitates the electrical connection between the energy receiving module 70 and the first circuit board 33.

[0085] See also Figure 3 In some embodiments, there is a gap between the first circuit board 33 and the partition 15, and the width D of the gap is greater than 0.5 mm in a direction perpendicular to the center line of the handle shell 11.

[0086] In the case where the width D of the gap between the first circuit board 33 and the partition 15 is less than or equal to 0.5 mm, due to the presence of components on the first circuit board 33, during the assembly of the first circuit board 33, the first circuit board 33 may be scraped against the partition 15, thereby causing damage to the first circuit board 33. In the case where the width D of the gap between the first circuit board 33 and the partition 15 is greater than 0.5 mm, the gap between the first circuit board 33 and the partition 15 is larger. During the assembly of the first circuit board 33, the first circuit board 33 will not be scraped against the partition 15.

[0087] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the handle housing 11 is provided with a control area 19, the driving member 31 includes a first side 313 and a second side 315 opposite to each other, and the first circuit board 33 is disposed on the second side 315 of the driving member 31. The movement 30 also includes a second circuit board 35 located in the handle housing 11, the second circuit board 35 is disposed on the first side 313 of the driving member 31 and corresponds to the control area 19, and the second circuit board 35 is electrically connected to the first circuit board 33 through a second conductive member 36.

[0088] Specifically, the control area 19 corresponds to the first circuit board 33, and the control area 19 is used to control the working state of the oral care device 100. For example, the control area 19 can control the opening and closing of the oral care device 100 and the switching between different modes. Among them, the modes of the oral care device 100 may include normal cleaning mode, deep cleaning mode and massage mode. The control area 19 may be a button or a touch screen. In the case where the control area 19 is a button, the user can control the opening and closing of the oral care device 100 and the switching of different modes by pressing, rotating or toggling. In the case where the control area 19 is a touch screen, the user can control the opening and closing of the oral care device 100 and the switching of different modes by single-clicking, double-clicking or sliding.

[0089] The second side 315 of the driving member 31 is the side close to the partition 15, and the first side 313 of the driving member 31 is the side away from the partition 15. The second circuit board 35 is a main control board, and the second circuit board 35 can be used to control the working state of the movement 30 and the working state of the energy receiving module 70. The second circuit board 35 is electrically connected to the first circuit board 33 through the second conductive member 36, and the second circuit board 35 is connected to the energy receiving module 70 through the first conductive member 34, so that the second circuit board 35 is electrically connected to the energy receiving module 70, and then the second circuit board 35 can control the working state of the energy receiving module 70.

[0090] See also Figure 3, the second conductive member 36 is a structure for electrically connecting the first circuit board 33 and the second circuit board 35. The second conductive member 36 can be, but is not limited to, a wire, a flexible circuit board, solder or a pin, etc. This application is described by taking the second conductive member 36 as a wire as an example. The movement 30 also includes a mounting member 39, which is arranged around the driving member 31, and the mounting member 39 is used to install and fix the driving member 31. The first circuit board 33 and the second circuit board 35 are both arranged in the gap between the mounting member 39 and the handle shell 11. Preferably, the mounting member 39 is provided with a through hole 391. The second conductive member 36 is penetrated by the through hole 391 (the second conductive member 36 passes through the gap between the mounting member 39 and the driving member 31) to electrically connect the first circuit board 33 and the second circuit board 35. If the mounting member 39 does not have a through hole 391, the second conductive member 36 needs to bypass the outer side surface of the mounting member 39 (the side of the mounting member 39 close to the side wall of the handle shell 11) to electrically connect the first circuit board 33 and the second circuit board 35, but there may be no space between the outer side surface of the mounting member 39 and the side wall of the handle shell 11 for the second conductive member 36 to pass through. In addition, the first circuit board 33 and the second circuit board 35 cannot be electrically connected by plugging or welding. Therefore, it is the best way for the second conductive member 36 to pass through a through hole to electrically connect the first circuit board 33 and the second circuit board 35. At this time, the stroke of the second conductive member 36 is shorter, so the second conductive member 36 (wire) can be set shorter, which can save the material of the second conductive member 36.

[0091] The control area 19 is arranged at a position on the first side 313 of the handle shell 11 close to the driving member 31, and the energy receiving module 70 is arranged at a position on the second side 315 of the handle shell 11 close to the driving member 31, so that the control area 19 and the energy receiving module 70 are respectively located on opposite sides of the handle shell 11. When the user holds the handle 10 and brushes his teeth, the side where the control area 19 is located is usually closer to the ground than the side where the energy receiving module 70 is located. When brushing teeth, water flow and foam tend to flow to one side of the control area 19, so that the energy receiving module 70 can be prevented from being affected by water flow and foam.

[0092] See also Figure 4 and Figure 5 In some embodiments, a buffer pad 131 is provided on the side of the cover plate 13 and / or the energy receiving module 70 facing the cover plate 13 , and the buffer pad 131 is used to buffer the contact force between the cover plate 13 and the energy receiving module 70 .

[0093] The buffer pad 131 is provided between the cover plate 13 and the energy receiving module 70. During the assembly process between the energy receiving module 70 and the cover plate 13, the buffer pad 131 can buffer the collision between the energy receiving module 70 and the cover plate 13 to avoid damage to the energy receiving module 70. After the energy receiving module 70 and the cover plate 13 are assembled with the handle shell 11, the buffer pad 131 is squeezed by both the energy receiving module 70 and the cover plate 13. At this time, the buffer pad 131 can be used to limit the movement of the energy receiving module 70 so that the installation of the energy receiving module 70 is more stable.

[0094] The material of the buffer pad 131 may be, but is not limited to, foam, sponge, rubber, and silicone. In one embodiment, the buffer pad 131 may be provided on the side of the cover plate 13 facing the partition 15, the position of the buffer pad 131 corresponds to the position of the energy receiving module 70, and the area of ​​the buffer pad 131 is at least greater than the cross-sectional area of ​​the energy receiving module 70. At this time, the buffer pad 131 has a better buffering effect on the contact force between the cover plate 13 and the energy receiving module 70. In another embodiment, the buffer pad 131 may be provided on the side of the energy receiving module 70 facing the cover plate 13. The area of ​​the buffer pad 131 is at least greater than the cross-sectional area of ​​the energy receiving module 70. At this time, the buffer pad 131 has a better buffering effect on the contact force between the cover plate 13 and the energy receiving module 70. In another embodiment, the side of the cover plate 13 facing the partition 15 is provided with a buffer pad 131, and the side of the energy receiving module 70 facing the cover plate 13 is also provided with a buffer pad 131. At this time, the buffer pad 131 has a better buffering effect on the contact force between the cover plate 13 and the energy receiving module 70 .

[0095] See also Figures 1 to 3 In some embodiments, the handle housing 11 includes a peripheral housing portion 113 and an end housing portion 115 connected to each other, the driving member 31 is accommodated in the peripheral housing portion 113, and the output shaft 311 extends from the end housing portion 115. The cover plate 13 extends to the end housing portion 115 and forms at least a part of the end housing portion 115, and the cover plate 13 formed as at least a part of the end housing portion 115 is provided with an energy transmission area 137.

[0096] The peripheral shell portion 113 is used to load the driving member 31 and is used for the user to hold. The output shaft 311 extends from the end shell portion 115 and is connected to the care part 50. The end shell portion 115 is bent toward the center axis of the handle shell 11 compared to the peripheral shell portion 113. In the direction from the movement 30 to the care part 50, the end shell portion 115 gradually approaches the center axis of the handle shell 11. The inclined extension of the end shell portion 115 is conducive to guiding the water flow and foam flowing from the care part 50 to the handle 10, so as to avoid the accumulation of water flow and foam at the position where the handle 10 is connected to the care part 50.

[0097] At least part of the cover plate 13 is provided with an energy-transmitting area 137, and the energy-transmitting area 137 is used for light, electromagnetic waves, ultrasonic waves or particle beams to pass through the energy-transmitting area 137. The present application is explained by taking the energy-transmitting area 137 being able to transmit light as an example. In the case where the energy-transmitting area 137 is able to transmit light, the energy-transmitting area 137 may be a light-transmitting area. The energy-transmitting area 137 corresponds to the position of the energy receiving module 70. The cover plate 13 and the end shell 115 do not block the energy receiving module 70, and the energy receiving module 70 can capture images through the energy-transmitting area 137. The material of the energy-transmitting area 137 (light-transmitting area) can be, but is not limited to, glass, organic glass, acrylic or light-transmitting film. The area of ​​the energy-transmitting area 137 is at least larger than the viewing angle range of the energy receiving module 70 on the cover plate 13. Preferably, the area of ​​the energy-transmitting area 137 is the same as the viewing angle range of the energy receiving module 70 on the cover plate 13. At this time, the energy receiving module 70 can capture images through the energy transmission area 137, and the non-energy transmission area 137 of the cover plate 13 can shield other positions of the energy receiving module 70, so that the oral care device 100 has better aesthetics.

[0098] See also Figures 3 to 5 In some embodiments, the cover 13 includes a first portion 133 and a second portion 135 connected to each other. The first portion 133 is connected to the peripheral shell portion 113, and the second portion 135 is connected to the end shell portion 115. Compared with the first portion 133, the second portion 135 is bent toward the central axis of the handle shell 11. In the direction from the care piece 50 to the movement 30, the second portion 135 gradually moves away from the central axis of the handle shell 11, and the second portion 135 is provided with an energy-transmitting area 137.

[0099] Among them, the second part 135 of the cover plate 13 is a component of the end shell 115. Since the installation space 17 is a sealed space, the second part 135 and the end shell 115 are sealed. In the case of a sealed connection between the second part 135 and the end shell 115, the water flow and foam flowing down from the care piece 50 will not enter the installation space 17 from the gap between the second part 135 and the end shell 115 to affect the energy receiving module 70. Compared with the first part 133, the second part 135 extends obliquely, which is conducive to diverting the water flow and foam flowing from the care piece 50 to the handle 10, and avoiding the accumulation of water flow and foam at the position where the handle 10 and the care piece 50 are connected.

[0100] See also Figure 2 and Figure 3 In some embodiments, the cover plate 13 protrudes in a direction away from the central axis of the handle shell 11 compared to the peripheral shell portion 113 .

[0101] During the process of brushing teeth, water and foam will flow along the care piece 50 toward the handle shell 11. The cover plate 13 protrudes in a direction away from the central axis of the handle shell 11 compared to the side wall of the handle shell 11, thereby reducing the flow of water and foam onto the cover plate 13, and further avoiding the influence of water and foam on the energy receiving module 70. And in the case where the cover plate 13 protrudes compared to the side wall of the handle shell 11, the main optical axis of the energy receiving module 70 can be aligned with the apex of the care piece 50 (the position of the bristles 53), so that the energy receiving module 70 can obtain a large amount of image information on both sides of the care piece 50.

[0102] See also Figure 3 and Figure 5 In some embodiments, an energy-transmitting area 137 is provided on the cover plate 13 or an energy-transmitting area 137 is provided on the handle shell 11. The energy-transmitting area 137 is used for the energy receiving module 70 to capture the graphic code of the care component 50 and the image of the care component 50 and / or the face through the energy-transmitting area 137.

[0103] In one embodiment, the movement 30 includes a mounting frame 37 located at the through hole 111, and a mounting position 371 is provided on the mounting frame 37. The energy receiving module 70 is installed at the mounting position 371 on the mounting frame 37, and corresponds to the energy transmission area 137. At this time, the handle 10 does not include the partition 15, and the mounting frame 37 can extend from the mounting member 39, and the mounting frame 37 extends from the through hole 111, and the mounting position 371 is used to install the energy receiving module 70. The energy receiving module 70 is first installed at the mounting position 371 of the movement 30, and then the cover plate 13 is connected to the handle shell 11.

[0104] In another embodiment, the cover plate 13 is provided with a mounting position 371, and the energy receiving module 70 is mounted on the mounting position 371 on the cover plate 13, and corresponds to the energy transmission area 137. The mounting position 371 can be integrally formed with the cover plate 13, and the mounting position 371 can also be detachably or non-detachably mounted on the cover plate 13. At this time, the energy receiving module 70 is first installed on the mounting position 371 on the cover plate 13, and the energy receiving module 70 and the cover plate 13 are then connected to the handle shell 11.

[0105] In other embodiments, the handle 10 may include a partition 15, and the mounting position 371 may be provided in a non-hollow area of ​​the partition 15. The mounting position 371 may be integrally formed with the partition 15, and the mounting position 371 may also be detachably or non-detachably mounted on the partition 15. At this time, the energy receiving module 70 is first mounted on the mounting position 371 of the partition 15, and then the cover plate 13 is connected to the handle shell 11.

[0106] The installation position 371 is used to install the energy receiving module 70. The installation position 371 and the limiting member 153 jointly install and limit the energy receiving module 70, so that the energy receiving module 70 can be stably installed in the installation space 17, avoiding collision between the energy receiving module 70 and the cover plate 13 or the handle shell 11. At the same time, the installation position 371 and the limiting member 153 can also make the energy receiving module 70 always correspond to the energy transmission area 137, avoiding the energy receiving module 70 from moving to be blocked by the non-energy transmission area 137, thereby causing the problem of being unable to shoot.

[0107] See also Figure 5 In some embodiments, the energy receiving module 70 includes an imaging module 71, which faces the nursing piece 50 and is used to acquire images.

[0108] Among them, the imaging module 71 corresponds to the energy transmission area 137, and the imaging module 71 can capture images through the energy transmission area 137. The imaging module 71 can convert the optical signal into a digital signal, and then convert the digital signal into image information. The imaging module 71 can be used to obtain an image of the graphic code on the care component 50, wherein the graphic code contains information such as the model of the care component 50. The imaging module 71 can also be used to capture images of the care component 50 and / or human features outside the oral cavity during the process of brushing teeth to know the position of the tooth area where the current care component 50 is located.

[0109] See also Figure 1 and Figure 5 In some embodiments, the oral care device 100 further includes a prompter 80. The prompter 80 is a device for reminding the user. The prompter 80 can be, but is not limited to, a voice prompter, a light prompter, a vibration prompter, a display prompter, and a sound alarm.

[0110] Specifically, in one embodiment, when the image analysis shows that the care piece 50 is not compatible, the prompter 80 is used to issue a prompt message. The care piece 50 is provided with a graphic code. When the care piece 50 is installed on the handle 10, the imaging module 71 can take a picture of the graphic code on the care piece 50 and transmit the graphic code to the processor of the oral care device 100. The processor can analyze whether the model of the care piece 50 is compatible with the model of the handle 10 according to the graphic code. When the care piece 50 is not compatible with the handle 10, the prompter 80 is used to issue a prompt message.

[0111] In one example, the prompter 80 is a voice prompter. When the processor analyzes that the care piece 50 is incompatible with the handle 10, the voice prompter can issue a voice to remind the user. For example, after the incompatible care piece 50 is assembled with the handle 10, the voice prompter can issue a voice prompt such as "the care piece 50 is incompatible with the handle 10" to remind the user. In another example, the prompter 80 is a light prompter. When the processor analyzes that the care piece 50 is incompatible with the handle 10, the light prompter can emit light to remind the user. For example, after the incompatible care piece 50 is assembled with the handle 10, the light prompter can emit red light, yellow light, etc. to remind the user. In another example, the prompter 80 is a vibration prompter. When the processor analyzes that the care piece 50 is incompatible with the handle 10, the vibration prompter can generate vibration to remind the user. In another example, the prompter 80 is a display prompter. When the processor analyzes that the care piece 50 is incompatible with the handle 10, the display prompter can appear on the display screen with a characteristic image, text or color to remind the user. For example, after the incompatible nursing part 50 is assembled with the handle 10, the display prompter may display a pattern such as "×" on the display screen to prompt the user, or may display a text such as "incompatible" on the display screen to prompt the user. In another example, the prompter 80 is a sound alarm. When the processor analyzes that the nursing part 50 and the handle 10 are incompatible, the sound alarm may emit a sound such as "di di" or "du du" to remind the user. For example, after the incompatible nursing part 50 is assembled with the handle 10, the sound alarm may emit a loud "di di" sound to remind the user.

[0112] See also Figure 1 and Figure 5 In other embodiments, when the imaging module 71 is working, the prompter 80 is used to issue a prompt message. When the imaging module 71 starts to capture images, the prompter 80 is used to issue a prompt message, so that the user can know that the imaging module 71 has started to work, and the user experience is better. And when the user knows that the imaging module 71 is working, the user can control the shooting range of the imaging module 71, so as to avoid the imaging module 71 from capturing the room or others, etc., and can better protect the user's privacy.

[0113] In one example, the prompter 80 is a voice prompter. When the imaging module 71 starts working, the voice prompter can issue a voice to remind the user. For example, after the imaging module 71 starts working, the voice prompter can issue a voice prompt such as "start working" to remind the user. In another example, the prompter 80 is a light prompter. When the imaging module 71 starts working, the light prompter can emit light to remind the user. For example, after the imaging module 71 starts working, the light prompter can emit red light, yellow light, etc. to remind the user. In another example, the prompter 80 is a vibration prompter. When the imaging module 71 starts working, the vibration prompter can generate vibration to remind the user. In another example, the prompter 80 is a display prompter. When the imaging module 71 starts working, the display prompter can appear a characteristic image, text or color on the display screen to remind the user. For example, after the imaging module 71 starts working, the display prompter can appear a text prompt such as "start working" on the display screen to remind the user. In another example, the prompter 80 is a sound alarm. When the imaging module 71 starts working, the sound alarm can emit a sound such as "di di" or "beep" to remind the user. For example, after the imaging module 71 starts working, the sound alarm can emit a louder "di di" sound to remind the user.

[0114] See also Figure 1 and Figure 5 In some other embodiments, when it is found out from the image analysis that the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the prompter 80 is used to issue a prompt message. The tooth area can be divided into the outer side, the inner side and the chewing surface, etc. The preset time threshold is the optimal operation time of the care component 50 in each tooth area, which has been set by the care component 50 before leaving the factory. For example, the preset time threshold is 2 minutes. In one example, when the processor analyzes the image taken by the imaging module 71 and finds that the operation time of the care component 50 in the tooth area on the outer side is less than 2 minutes, the prompter 80 may issue a prompt message. After the user knows the information, he can control the care component 50 to continue to operate in the tooth area.

[0115] In one example, the prompter 80 is a voice prompter. When the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the voice prompter can issue a voice to remind the user. For example, the voice prompter can issue a voice prompt such as "not enough time" to remind the user. In another example, the prompter 80 is a light prompter. When the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the light prompter can emit light to remind the user. For example, the light prompter can emit red light, yellow light, etc. to remind the user. In another example, the prompter 80 is a vibration prompter. When the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the vibration prompter can generate vibration to remind the user. In another example, the prompter 80 is a display prompter. When the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the display prompter can appear a characteristic image, text or color on the display screen to remind the user. For example, the display prompter can appear a text prompt such as "not enough time" on the display screen to remind the user. In another example, the prompter 80 is a sound alarm. When the operation time of the care component 50 in the predetermined tooth area is less than the preset time threshold, the sound alarm may emit a "di di" or "beep" sound to remind the user.

[0116] See also Figure 1 and Figure 5 In some further embodiments, when it is found out from the image analysis that the usage time of the care component 50 is longer than the preset upper limit of the usage time, the prompter 80 is used to issue a prompt message. The usage time of the care component 50 refers to the time from when a new care component 50 is installed on the handle 10 and is used by the user until the care component 50 is retired. The preset upper limit of the usage time refers to the optimal usage time of the care component 50 set by the oral care device 100 before leaving the factory. For example, the preset upper limit of the usage time of the care component 50 is 3 months, 6 months, or 8 months, etc. In the case that the usage time of the care component 50 is longer than the preset upper limit of the usage time, for example, the preset upper limit of the usage time of the care component 50 is 6 months, the prompter 80 will issue a prompt message after the usage time of the care component 50 exceeds 6 months.

[0117] In one example, the prompter 80 is a voice prompter. When the use time of the nursing part 50 is longer than the preset upper limit of the time, the voice prompter can issue a voice to remind the user. For example, the voice prompter can issue a voice prompt such as "exceeded the deadline" to remind the user. In another example, the prompter 80 is a light prompter. When the use time of the nursing part 50 is longer than the preset upper limit of the time, the light prompter can emit light to remind the user. For example, the light prompter can emit red light, yellow light, etc. to remind the user. In another example, the prompter 80 is a vibration prompter. When the use time of the nursing part 50 is longer than the preset upper limit of the time, the vibration prompter can generate vibration to remind the user. In another example, the prompter 80 is a display prompter. When the use time of the nursing part 50 is longer than the preset upper limit of the time, the display prompter can appear a characteristic image, text or color on the display screen to remind the user. For example, the display prompter can appear on the display screen with text such as "exceeded the deadline" to remind the user. In another example, the prompter 80 is a sound alarm. When the usage time of the nursing component 50 is longer than the preset upper limit of the usage time, the sound alarm may emit a "di di" or "beep" sound to remind the user.

[0118] See also Figure 1 and Figure 5 Furthermore, in some embodiments, the oral care device 100 further includes a display 90. The display 90 is used to display relevant information of the care component 50 obtained by analyzing the image. For example, the processor can obtain information such as the model, usage time, wear degree, and material of the bristles 53 of the care component 50 by analyzing the image captured by the imaging module 71. The above information can be presented through the display 90, and the user can intuitively obtain relevant information of the care component 50 through the display 90, and the user experience is good.

[0119] See also Figure 1 In some embodiments, when the oral care device 100 is awakened, the energy receiving module 70 is started. The oral care device 100 being awakened means that when the oral care device 100 is not turned on (has not started to vibrate and clean teeth), some functions of the oral care device 100 start to run first. For example, when the oral care device 100 is awakened, the energy receiving module 70 and the display 90 can be started at the same time. In one example, when the user's hand holds the handle 10, the handle 10 feels the temperature of the human body, and the oral care device 100 is awakened. At the same time as the oral care device 100 is awakened, the energy receiving module 70 is started to start taking images. The energy receiving module 70 does not need to be started using a specific switch, and the startup of the energy receiving module 70 is more intelligent, and the user's operation is relatively simple.

[0120] See also Figure 1 and Figure 5 In some embodiments, when the energy receiving module 70 is started and the care piece 50 is found to be compatible based on the image analysis, the oral care device 100 is turned on. After the oral care device 100 is awakened, the energy receiving module 70 is started and starts to capture images. When the imaging module 71 captures the graphic code on the care piece 50 and analyzes the graphic code to find that the care piece 50 is compatible with the handle 10, the oral care device 100 is automatically turned on, so that the care piece 50 starts to vibrate. At this time, the startup operation of the oral care device 100 is relatively simple, easy for users to operate, and the user experience is good.

[0121] The oral care device 100 of the embodiment of the present application is provided with a through hole 111 and a cover plate 13 on the handle shell 11. During the assembly process, the movement 30 can be assembled first, and then the energy receiving module 70 and the cover plate 13 can be installed on the handle shell 11 through the through hole 111. The energy receiving module 70 of the embodiment of the present application is not easily damaged during the assembly process.
