Description

Technical Field

[0001] The present application relates to the field of oral cleaning, and more specifically, to an oral care device. Background Art

[0002] An oral care device is an electric device that uses a high-speed vibrating movement motor to drive the brush head to rotate or vibrate to clean teeth. According to user needs, an antenna for sending and / or receiving external signals may be provided in the oral care device to send operating information to a control terminal or cloud, or to receive instructions sent by a terminal or cloud. However, the range of the antenna currently set in the oral care device to send and / or receive signals is easily blocked by the metal shell of the oral care device, resulting in poor signal strength and quality. Utility Model Content

[0003] The embodiments of the present application provide an oral care device, which is at least used to solve the problem that the strength and quality of the transmitted signal in the oral care device are poor.

[0004] The oral care device of the embodiment of the present application includes a metal handle shell, a non-metal panel and a communication component. The handle shell is surrounded by a receiving cavity and is provided with a through hole connected to the receiving cavity. The panel is installed on the handle shell and covers the through hole. The communication component is arranged in the receiving cavity, and the communication component includes a signal transceiver, and the signal transceiver is arranged corresponding to the panel. The signal transceiver is used to send signals to the outside of the handle shell and / or receive signals outside the handle shell, and the panel is used for the signals sent by the signal transceiver and / or the signals received by the signal transceiver to pass through.

[0005] During the signal propagation process, the metal handle shell will cause the impedance of the signal transceiver to have frequency deviation and seriously affect the transceiver performance of the signal transceiver. At the same time, the metal handle shell will also absorb and shield the signal sent by the signal transceiver or the signal transmitted from the external device to the signal transceiver, resulting in a large signal loss during the transmission process, making it difficult to accurately transmit information or instructions, etc. Therefore, when the signal transceiver is set at a position opposite to the panel, the non-metallic panel is partially or completely located in the signal transceiver area of ​​the signal transceiver, and the metal handle shell can be staggered from the signal transceiver area, so as to avoid the influence of the metal handle tube on the signal transceiver function of the signal transceiver as much as possible, and ensure the transmission quality and signal strength of the signal.

[0006] In some embodiments, the panel is mounted on a first side of the handle housing. The oral care device further comprises a first circuit board, and the signal transceiver is disposed on a side of the first circuit board facing the panel.

[0007] When the panel is opposite to the first circuit board, the signal transceiver arranged on the first circuit board can also be opposite to the panel, so that there is no obstruction of other structures of the oral care device between the panel and the signal transceiver. The signal sent by the signal transceiver or the signal sent by the external device to the signal transceiver and can be received by the signal transceiver can directly pass through the non-metallic panel, and the signal loss during the transmission process is less.

[0008] In some embodiments, the oral care device further comprises a functional device, which is disposed in the accommodating cavity and opposite to the panel. The functional device is electrically connected to the first circuit board, and the signal transceiver is disposed within a predetermined distance range of the functional device.

[0009] The functional device is a device that can realize different functions of the oral care device. Since the functional device needs to always be opposite to the panel to realize the function, when the distance between the functional device and the signal transceiver is within the predetermined distance range of the functional device, the signal receiving and sending area of ​​the signal transceiver can also overlap with the panel as much as possible, so that the signal is less blocked by the metal handle shell or other structures of the oral care device.

[0010] In some embodiments, the panel includes a pressing portion. The functional device includes a button, which is disposed in the accommodating cavity and electrically connected to the first circuit board, and the button is opposite to the pressing portion. When the pressing portion is pressed, the button is triggered. The on-axis distance between the signal transceiver and the button on the central axis of the handle shell is less than a first preset distance.

[0011] The pressing portion of the panel is opposite to the button, and when the user presses the pressing portion, the pressing portion can trigger the button to change the operation mode of the oral care device. Since the button always corresponds to the panel, when the distance between the button and the signal transceiver along the central axis of the handle shell is less than the first preset distance, the signal transceiver area of ​​the signal transceiver can correspond to at least part of the structure of the panel, and the signal can be transmitted to the external device through the panel or received by the signal transceiver from the outside through the panel, and the signal transmission effect is better.

[0012] In some embodiments, the panel includes a light-transmitting portion. The functional device includes an indicator, which is disposed in the accommodating cavity and electrically connected to the first circuit board. The indicator is opposite to the light-transmitting portion, and the indicator is used to emit light through the light-transmitting portion toward the outside of the handle shell. The on-axis distance between the signal transceiver and the indicator on the central axis of the handle shell is less than a second preset distance.

[0013] The light-transmitting portion of the panel allows the light emitted by the indicator to be transmitted to the outside of the handle shell to indicate the current working state of the oral care device. Since the indicator always corresponds to the light-transmitting portion of the panel, when the distance between the indicator and the signal transceiver along the central axis of the handle shell is less than the second preset distance, the signal transceiver area of ​​the signal transceiver can correspond to at least part of the light-proof structure of the panel, and the signal can be transmitted to the external device through the panel or received by the signal transceiver from the outside through the panel, and the signal transmission effect is better.

[0014] In some embodiments, the panel includes a light-transmitting portion. The functional device includes a display screen, which is disposed in the accommodating cavity and electrically connected to the first circuit board. The display screen is opposite to the light-transmitting portion, and the display screen is used to display an image to the outside of the handle shell through the light-transmitting portion. The on-axis distance between the signal transceiver and the display screen on the central axis of the handle shell is less than a third preset distance.

[0015] The display area of ​​the display screen can correspond to the light-transmitting portion of the panel so that the user can see the display screen outside the handle shell. Since the indicator always corresponds to the light-transmitting portion of the panel, when the distance between the display screen and the signal transceiver along the central axis of the handle shell is less than the second preset distance, the signal transceiver area of ​​the signal transceiver can correspond to at least part of the light-proof structure of the panel, and the signal can be transmitted to the external device through the panel or received by the signal transceiver from the outside through the panel, and the signal transmission effect is better.

[0016] In some embodiments, the functional device is spaced apart from the panel in a direction perpendicular to a central axis of the handle housing.

[0017] Since some functional devices contain metal parts or other structures that can block signals, shield signals or affect signal transmission, when the functional device is separated from the panel, the edge of the signal transceiver area of ​​the signal transceiver arranged near the functional device can be staggered with the edge of the functional device, so that the functional device cannot block the signal transceiver area of ​​the signal transceiver or reduce the blocking area of ​​the signal transceiver area by the functional device, thereby improving the signal transmission effect.

[0018] In some embodiments, the panel is light-transmissive but not transparent. Alternatively, the panel includes a first area and a second area, the signal transceiver is opposite to the first area, the oral care device further includes a functional device, the functional device is opposite to the second area, the first area is light-impermeable, and the second area is light-transmissive.

[0019] In the case where the portion of the panel opposite to the signal transceiver is light-transmissive but not transparent or completely opaque, the signal transceiver disposed in the handle shell and opposite to the panel can be partially shielded by the opaque portion of the panel or the opaque first area, so that the appearance of the oral care device is more beautiful. The functional device is opposite to the light-transmissive second area, so that the optical signal emitted by the functional device can pass through the panel to be recognized.

[0020] In some embodiments, the oral care device further comprises a first circuit board and a functional device, wherein the functional device is arranged on the first circuit board. The communication component comprises a signal transceiver, a matching circuit and a main chip. The signal transceiver is arranged on the first circuit board and is spaced apart from the functional device. The matching circuit is arranged on the first circuit board. The main chip is arranged on the first circuit board and is spaced apart from the functional device and the signal transceiver, the main chip is electrically connected to the functional device, and the main chip is also electrically connected to the signal transceiver through the matching circuit.

[0021] The main chip arranged on the first circuit board can read the signal received by the signal transceiver and control the signal transceiver to send a signal. At the same time, the signal transceiver arranged on the board can also occupy a smaller space in the handle shell and avoid being blocked by other structures in the handle shell.

[0022] In some embodiments, the first circuit board includes a first end and a second end opposite to each other, the first end is closer to the bottom of the handle shell than the second end, and the signal transceiver, the functional device and the matching circuit are closer to the second end than the main chip.

[0023] The matching circuit is arranged between the main chip and the signal transceiver, which can reduce the installation position occupied by the matching circuit on the first circuit board as much as possible, so that the electrical components on the first circuit board can be installed more closely and the layout of the electrical components on the first circuit board can be more reasonable. At the same time, arranging the signal transceiver closer to the second end can make the signal transceiver and the panel be arranged correspondingly, so that the signal sent by the signal transceiver or the signal received by the signal transceiver can pass through the panel as much as possible without being blocked by the metal handle shell.

[0024] In some embodiments, the distance between the signal transceiver and the top end of the handle shell does not exceed 1 / 4 of the total length of the handle shell.

[0025] Setting the signal transceiver at a distance less than 1 / 4 of the total length of the handle shell from the top of the handle shell can enable the signal transceiver to be located on the side of the handle shell closer to the top. On the one hand, the signal transceiver corresponds to the panel that is also set on the side of the handle shell closer to the top. On the other hand, it can also prevent the user from blocking the signal receiving and transmitting path of the signal transceiver when holding the oral care device.

[0026] In some embodiments, the handle shell includes a first side and a second side, the panel is mounted on the second side of the handle shell, and the signal transceiver is disposed on the second side of the handle shell and opposite to the panel. The oral care device also includes a first circuit board, the first circuit board is disposed on the first side of the handle shell, and the signal transceiver is electrically connected to the first circuit board.

[0027] The panel can be arranged at any position of the handle shell. When the panel and the first circuit board are arranged on different sides of the handle shell, the signal end of the signal transceiver will always correspond to the panel, so that the signal sent by the signal transceiver or the signal that the signal transceiver can receive is not blocked or shielded by the handle shell as much as possible.

[0028] In some embodiments, the communication component further includes a second circuit board, the second circuit board is located on the second side of the handle shell, the signal transceiver is disposed on the second circuit board, and the signal transceiver is electrically connected to the first circuit board through the second circuit board and the conductive member.

[0029] When the signal transceiver is disposed on an independent second circuit board, the signal transceiver can be an independent structure mounted on the second circuit board, or a circuit structure capable of transmitting and receiving signals and disposed integrally with the second circuit board. When the signal transceiver is disposed on an independent second circuit board, the second circuit board and the signal transceiver can be disposed at any position in the handle shell that can receive or transmit signals, and the arrangement position of the signal transceiver is more flexible.

[0030] In certain embodiments, the oral care device further comprises a core assembly, wherein the core assembly is disposed in the accommodating cavity, the signal transceiver is fixed to the core assembly, and a signal end of the signal transceiver is opposite to the panel.

[0031] The movement assembly can be used to install the signal transceiver. In the case where the signal transceiver is a separate antenna, the signal transceiver can pass through the movement assembly, and the electrical connection end of the signal transceiver can be electrically connected to a first circuit board installed on the movement assembly and located on a different side from the panel. The signal end of the signal transceiver can extend from the movement assembly or be embedded in the surface of the movement assembly, and always remain corresponding to the panel, so as to prevent the signal sent by the signal end of the signal transceiver or the signal received by the signal end of the signal transceiver from being blocked by other structures of the oral care device.

[0032] In some embodiments, the oral care device further comprises a first circuit board, and the signal transceiver comprises a plurality of them. Each of the signal transceiver is opposite to a different position of the panel and is electrically connected to the first circuit board. Alternatively, the panel comprises a plurality of them, and the plurality of the panels are mounted at different positions of the handle housing, and each of the panels corresponds to at least one of the signal transceiver.

[0033] Multiple signal transceivers can enhance the strength of the signal sent outward, and multiple signal transceivers arranged in different positions can also increase the signal transceiver area of ​​the signal transceiver, so that the signal range that the signal transceiver can receive and / or the signal range that the signal transceiver can send are wider. At the same time, each signal transceiver corresponds to a panel to prevent the signal sent by the signal end of the signal transceiver or the signal received via the signal end of the signal transceiver from being blocked by other structures of the oral care device. In the case of multiple panels, each panel can correspond to one signal transceiver or multiple signal transceivers.

[0034] In some embodiments, the panel is seamlessly connected to the through hole.

[0035] The connection between the panel and the inner wall of the through hole of the handle shell can be either integrally formed or separately formed. In the case where the panel and the handle shell are separately formed, a seamless sealing structure is provided between the panel and the inner wall of the through hole of the handle shell, so that external water vapor, dust or foam will not enter the handle shell through the gap between the panel and the inner wall of the through hole of the handle shell, thereby avoiding structural damage in the oral care device.

[0036] In certain embodiments, the oral care device further comprises an inner liner, wherein the inner liner is disposed in the accommodating cavity and connected to the handle shell, the inner liner is provided with a supporting platform at a position corresponding to the through hole, and the panel is mounted on the supporting platform.

[0037] Since the handle shell is made of metal, the internal structure of the oral care device is difficult to fix on the metal handle shell, and the cost of making a fixed structure in the metal handle shell is high. The inner liner made of non-metallic material can be used to connect the internal structure of the oral care device, which can reduce the manufacturing cost of the oral care device on the one hand, and prevent the internal structure of the oral care device from shaking in the handle shell on the other hand, thereby protecting the internal structure of the oral care device. The support platform provided on the inner liner can more conveniently install the panel, and can also enable the panel to be tightly combined with the metal handle shell.

[0038] In some embodiments, the oral care device further comprises an inner liner and a core assembly. The inner liner is disposed in the accommodating cavity and connected to the handle shell, and the inner liner is provided with a connecting portion. The core assembly is disposed in the inner liner, and a matching portion is provided on the core assembly, and the connecting portion is slidably matched with the matching portion to connect the core assembly to the inner liner.

[0039] The connecting portion of the lining is arranged on the inner peripheral wall of the lining, and the matching portion of the movement assembly is arranged on the outer peripheral wall of the movement assembly. When the connecting portion and the matching portion are combined with each other, the movement assembly can be installed in the lining, and under the cooperation of the connecting portion and the matching portion, the movement assembly will not shake or rotate violently in the lining, thereby improving the stability of the connection between the structures in the oral care device.

[0053] See also Figure 1 and Figure 2 , and combined with Figure 3 The oral care device 100 of the present application includes a metal handle shell 10, a non-metal panel 20 and a communication component 30. The handle shell 10 is surrounded by a receiving cavity 101 and is provided with a through hole 103 connected to the receiving cavity 101. The panel 20 is installed on the handle shell 10 and covers the through hole 103. The communication component 30 is arranged in the receiving cavity 101, and the communication component 30 includes a signal transceiver 31, and the signal transceiver 31 is arranged corresponding to the panel 20. The signal transceiver 31 is used to send signals to the outside of the handle shell 10 and / or receive signals outside the handle shell 10, and the panel 20 is used for the signals sent by the signal transceiver 31 and / or the signals received by the signal transceiver 31 to pass through.

[0054] In the oral care device 100 of the present application, the signal transceiver 31 is arranged at a position opposite to the panel 20, the non-metallic panel 20 is partially or completely located in the signal transceiver area of ​​the signal transceiver 31, and the metal handle shell 10 can be staggered from the signal transceiver area, so as to avoid the influence of the metal handle tube on the signal transceiver function of the signal transceiver 31 as much as possible, thereby ensuring the signal transmission quality and signal strength.

[0055] The oral care device 100 is further described below with reference to the accompanying drawings.

[0056] See also Figure 3 and Figure 4 In some embodiments, the handle shell 10 is roughly a shell structure that can accommodate part of the structure of the oral care device 100. The handle shell 10 is provided with a receiving cavity 101, and part of the structure of the oral care device 100 can be arranged in the receiving cavity 101. The material of the handle shell 10 includes but is not limited to metal or alloy. During the propagation of the signal, the metal handle shell 10 will cause the impedance of the signal transceiver 31 to have a frequency deviation and seriously affect the transceiver performance of the signal transceiver 31. At the same time, the metal handle shell 10 will also absorb and shield the signal sent by the signal transceiver 31 or the signal transmitted from the external device to the signal transceiver 31, resulting in a large signal loss during the transmission process, making it difficult to accurately transmit information or instructions. The through hole 103 provided on the metal handle shell 10 can allow the signal to pass through, and the panel 20 covering the through hole 103 can also allow the signal to pass through, thereby reducing the shielding and shielding of the signal by the metal handle shell 10.

[0057] Specifically, in some embodiments, the handle shell 10 includes a top end 15 and a bottom end 17 that are disposed opposite to each other, and the handle shell 10 has a central axis A, which is an axis that divides the handle shell 10 into two relatively symmetrical parts. When the handle shell 10 is an axisymmetric three-dimensional structure, the central axis A of the handle shell 10 passes through the center of the top end 15 of the handle shell 10 and the center of the bottom end 17 of the handle shell 10, that is, the direction X of the central axis A of the handle shell 10 can be either a straight line extending direction from the center of the top end 15 of the handle shell 10 to the center of the bottom end 17 of the handle shell 10, or a straight line extending direction from the center of the bottom end 17 of the handle shell 10 to the center of the top end 15 of the handle shell 10, which is not limited here. The direction Y perpendicular to the central axis A of the handle shell 10 can be any straight line extending direction of the opposite sides of the handle shell 10, which is not limited here. The outer contour shape of the cross section of the handle shell 10 includes but is not limited to a perfect circle, an ellipse, a triangle, a quadrilateral or a pentagon, etc. In some embodiments, along the direction X of the central axis A of the handle shell 10, from the bottom end 17 of the handle shell 10 to the top end 15 of the handle shell 10, the outer contour size of the cross section of the handle shell 10 gradually changes, for example: the outer contour size of the cross section of the handle shell 10 first remains unchanged and then gradually decreases, first increases and then decreases, or changes multiple times. In other embodiments, along the direction X of the central axis A of the handle shell 10, from the bottom end 17 of the handle shell 10 to the top end 15 of the handle shell 10, the outer contour size of the cross section of the handle shell 10 always remains unchanged.

[0058] More specifically, please combine Figure 1 In some embodiments, the handle shell 10 includes a first side 11 and a second side 13. The first side 11 of the handle shell 10 and the second side 13 of the handle shell 10 can be two sides disposed opposite to each other along a direction Y perpendicular to the central axis A of the handle shell 10, or two sides disposed adjacent to each other, which is not limited here. Figure 2 As shown, the signal transceiver 31 is disposed on the first side 11 of the handle shell 10, and the through hole 103 is also opened on the first side 11 of the handle shell 10, so that the panel 20 installed at the through hole 103 and located on the first side 11 of the handle shell 10 can be opposite to the signal transceiver 31. In other embodiments, such as Figure 1As shown, the signal transceiver 31 is arranged on the second side 13 of the handle shell 10, and the through hole 103 is also opened on the second side 13 of the handle shell 10, so that the panel 20 installed at the through hole 103 and located on the second side 13 of the handle shell 10 can be opposite to the signal transceiver 31. The signal transceiver 31 is opposite to the panel 20, which means that the signal transceiver range of the signal transceiver 31 at least partially overlaps with the panel 20, the edge of the signal transceiver range is completely staggered with the edge of the through hole 103 of the handle shell 10 (that is, the edge of the panel 20), the signal transceiver 31 and the panel 20 are directly correspondingly arranged along the direction Y perpendicular to the central axis A of the handle shell 10, or the signal transceiver 31 is completely located in the projection of the panel 20 along the direction Y perpendicular to the central axis A of the handle shell 10, etc. The signal transceiver 31 and the panel 20 are always relative to each other to ensure that the signal sent by the signal end of the signal transceiver 31 is received by the external device through the panel 20 as much as possible, or the signal sent by the external device is transmitted to the signal end of the signal transceiver 31 through the panel 20 as much as possible, so as to avoid the metal handle shell 10 blocking the signal or affecting the transmission quality of the signal.

[0059] See also Figure 3 and Figure 4 In some embodiments, the panel 20 is a plate-like structure that is disposed at the through hole 103 of the handle shell 10 and can block the through hole 103. The panel 20 is made of non-metallic material, and the material of the panel 20 includes but is not limited to plastic, silicone or rubber. The signal sent by the signal transceiver 31 or the signal transmitted from the outside to the signal transceiver 31 can pass through the panel 20. Therefore, when the signal transceiver 31 is closer to the panel 20 relative to the position of the handle shell 10, the signal transceiver area of ​​the signal transceiver 31 can overlap more with the panel 20 and reduce the shielding and shielding effect of the metal handle shell 10 on the signal. In some embodiments, the panel 20 is mounted on the first side 11 of the handle shell 10. At this time, the signal end of the signal transceiver 31 is also located on the first side 11 of the handle shell 10 and is arranged opposite to the panel 20. In other embodiments, the panel 20 is installed on the second side 13 of the handle shell 10. In this case, the signal transceiver 31 can be arranged on the second side 13 of the handle shell 10, or partially arranged on the first side 11 of the handle shell 10, and the other part (i.e., the signal end) is arranged on the second side 13 of the handle shell 10 to always remain opposite to the panel 20.

[0060] Specifically, in some embodiments, the panel 20 may include a pressing portion 21. The pressing portion 21 is a partial structure or partial area on the panel 20 that can be deformed or slightly deformed. The pressing portion 21 may be composed of a flexible structure, and the material of the pressing portion 21 may be the same as or different from the material of other parts of the panel 20, which is not limited here. When the user applies force to the pressing portion 21 and deforms the pressing portion 21, the pressing portion 21 can trigger the trigger structure of the oral care device 100 provided in the handle shell 10, and realize the switching of different working modes of the oral care device 100, the opening or closing of the oral care device 100, and other functions.

[0061] More specifically, in some embodiments, the panel 20 may further include a light-transmitting portion 23. When the structure of the oral care device 100 disposed in the handle housing 10 and opposite to the light-transmitting portion 23 of the panel 20 emits light, the emitted light can be emitted to the outside of the handle housing 10 through the light-transmitting portion 23, so that the user can obtain information such as the current working state of the oral care device 100 and various parameters of the oral care device 100 based on information such as light changes or images formed by the light.

[0062] Furthermore, please combine Figure 5 In some embodiments, the entire area of ​​the panel 20 is a light-transmitting but opaque structure. At this time, the user cannot observe the internal structure of the handle shell 10 that is arranged opposite to the panel 20 from the outside, but the light emitted from the handle shell 10 can still be observed by the user. In other embodiments, the panel 20 includes a first area 201 and a second area 203, and the first area 201 and the second area 203 are connected, wherein the first area 201 is opaque and the second area 203 is light-transmitting. The signal transceiver 31 is opposite to the first area 201, so that the user cannot observe the specific structure of the signal transceiver 31 from the outside of the handle shell 10, and other luminous structures installed in the handle shell 10 can correspond to the light-transmitting second area 203, so that light is emitted from the second area 203 and observed by the user.

[0063] Furthermore, in some embodiments, the panel 20 and the through hole 103 are seamlessly connected. The connection between the panel 20 and the inner wall of the through hole 103 of the handle shell 10 can be either integrally formed or separately formed. In the case where the panel 20 and the handle shell 10 are separately formed, in some embodiments, a sealing structure is provided between the panel 20 and the inner wall of the through hole 103 of the handle shell 10 to fill the gap therebetween. In other embodiments, the panel 20 and the inner wall of the through hole 103 of the handle shell 10 are seamlessly connected by interference connection, gluing connection or the like. The seamlessly connected panel 20 and the inner wall of the through hole 103 of the handle shell 10 can prevent external water vapor, dust or foam from entering the handle shell 10 through the gap between the panel 20 and the inner wall of the through hole 103 of the handle shell 10, thereby avoiding structural damage to the oral care device 100.

[0064] See also Figure 3 and Figure 4 In some embodiments, the communication component 30 is generally a structure that can send out signals according to instructions or receive and read signals sent by an external device to the oral care device 100 to obtain instructions. The types of communication components 30 include but are not limited to WIFI modules, Bluetooth modules or Zigbee, etc. The oral care device 100 may also include a first circuit board 40, which is a structure for electrically connecting to the communication component 30 to supply power to the communication component 30. In some embodiments, the signal transceiver 31 of the communication component 30 is disposed on the first circuit board 40 and is directly electrically connected to the first circuit board 40. In other embodiments, the signal transceiver 31 is disposed on other structures of the oral care device 100 and is indirectly electrically connected to the first circuit board 40.

[0065] Furthermore, in some embodiments, the signal transceiver 31 is an electrical component or a group of electrical components for receiving external signals and sending signals to the outside. In some embodiments, the signal transceiver 31 may be a conductive metal antenna or a glass fiber antenna, etc. In other embodiments, the types of the signal transceiver 31 include but are not limited to an IPEX external antenna, an onboard antenna or a ceramic antenna, etc. Among them, the IPEX external antenna is a structure that is separately installed in the handle shell 10 and can be connected to the external antenna, and the signal quality it can provide is better. The onboard antenna can use PCB (hard circuit board and / or flexible circuit board, etc.) as a medium to directly set the antenna on the PCB. The ceramic antenna is a signal transceiver element separately set in the handle shell 10, and its signal end is located in the ceramic shell, which is not easily damaged by touching and is easy to assemble.

[0066] Specifically, please combine Figure 6In some embodiments, along the direction X of the central axis A of the handle shell 10, the distance H1 between the signal transceiver 31 and the top end 15 of the handle shell 10 does not exceed 1 / 4 of the total length H0 of the handle shell 10. When the signal transceiver 31 is arranged at a position where the distance H1 between the signal transceiver 31 and the top end 15 of the handle shell 10 is less than 1 / 4 of the total length H0 of the handle shell 10, the signal transceiver 31 can be located on the side of the handle shell 10 closer to the top end 15 of the handle shell 10. On the one hand, since the panel 20 is also arranged on the side closer to the top end 15 of the handle shell 10 relative to the peripheral wall of the handle shell 10, when the distance H1 between the signal transceiver 31 and the top end 15 of the handle shell 10 is less than or equal to 1 / 4 of the total length H0 of the handle shell 10, the signal transceiver 31 can correspond to the panel 20 which is also arranged on the side of the handle shell 10 closer to the top end 15. On the other hand, when the signal transceiver 31 is located on the side of the handle shell 10 closer to the top 15 of the handle shell 10, the signal transceiver 31 and the position where the user holds the oral care device 100 can be staggered and the user can avoid blocking the signal receiving and transmitting path of the signal transceiver 31 when holding the oral care device 100.

[0067] More specifically, in some embodiments, the signal transceiver 31 may include multiple ones. Each signal transceiver 31 is opposite to the panel 20, and each signal transceiver 31 is directly or indirectly electrically connected to the first circuit board 40. Multiple signal transceivers 31 can enhance the strength of the signal sent outward, and multiple signal transceivers 31 arranged at different positions can also increase the signal transceiver area of ​​the signal transceiver 31, so that the signal range that the signal transceiver 31 can receive and / or the signal range that the signal transceiver 31 can send are wider. At the same time, each signal transceiver 31 corresponds to the panel 20 to prevent the signal sent by the signal end of the signal transceiver 31 or the signal received by the signal end of the signal transceiver 31 from being blocked by other structures of the oral care device 100. In some embodiments, the panel 20 includes one, and each signal transceiver 31 is respectively opposite to different positions of the same panel 20. In other embodiments, the panel 20 includes multiple panels 20, and multiple panels 20 are installed at different positions of the handle shell 10, and each panel 20 corresponds to at least one signal transceiver 31. When there are multiple panels 20 , each panel 20 may correspond to one signal transceiver 31 , or each panel 20 may correspond to multiple signal transceivers 31 .

[0068] Furthermore, in some embodiments, the communication component 30 may also include a matching circuit 33 and a main chip 35. The matching circuit 33 is arranged between the main chip 35 and the signal transceiver 31, and the matching circuit 33 includes a plurality of circuit elements. The matching circuit 33 can electrically connect the signal transceiver 31 and the main chip 35 so that the command signal sent by the main chip 35 can be transmitted to the signal transceiver 31 and / or the signal received by the signal transceiver 31 can be transmitted to the main chip 35 so that the main chip 35 controls the operation of other parts of the structure. The main chip 35 is a structure that controls the signal transceiver 31 and the matching circuit 33 and can receive and analyze the signal transmitted by the signal transceiver 31. The main chip 35 is arranged on the first circuit board 40 and is spaced from the signal transceiver 31. The main chip 35 is electrically connected to the signal transceiver 31 through the matching circuit 33. The main chip 35 can read the signal received by the signal transceiver 31 and control the signal transceiver 31 to send a signal. When the signal transceiver 31 is disposed on the first circuit board 40, the matching circuit 33 and the main chip 35 are both mounted on the first circuit board 40. At the same time, the signal transceiver 31 disposed on the board can also occupy a smaller space in the handle shell 10, and avoid other structures in the handle shell 10 from blocking the signal transceiver 31.

[0069] Furthermore, please combine Figure 1 and Figure 5 In some embodiments, the communication component 30 further includes a second circuit board 37, and the signal transceiver 31 is disposed on the second circuit board 37. The signal transceiver 31 is electrically connected to the first circuit board 40 through the second circuit board 37 and the conductive member. The conductive member is a structure that can electrically connect the signal transceiver 31, the matching circuit 33 and the main chip 35. The conductive member can be an independent wire or a circuit structure built into the first circuit board 40 and / or the second circuit board 37, and is not limited here. In the case where the signal transceiver 31 is disposed on the independent second circuit board 37, the signal transceiver 31 can be an independent structure installed on the second circuit board 37, or a circuit structure capable of transmitting and receiving signals that is integrally arranged with the second circuit board 37. In the case where the signal transceiver 31 is disposed on the independent second circuit board 37, the second circuit board 37 and the signal transceiver 31 can be disposed at any position in the handle shell 10 that can receive or send signals, and the setting position of the signal transceiver 31 is more flexible. When the signal transceiver 31 is disposed on the first side 11 of the handle housing 10 , the second circuit board 37 is located on the first side 11 of the handle housing 10 . When the signal transceiver 31 is disposed on the second side 13 of the handle housing 10 , the second circuit board 37 is located on the second side 13 of the handle housing 10 .

[0070] Specifically, in some embodiments, when the signal transceiver 31 is disposed on the second circuit board 37, the main chip 35 is installed on the first circuit board 40, and the matching circuit 33 can be installed on either the first circuit board 40 or the second circuit board 37. In some embodiments, the first circuit board 40 and the second circuit board 37 are electrically connected via a wire. In other embodiments, the second circuit board 37 is a flexible circuit board that can be directly connected to the first circuit board 40. The signal transceiver 31 is electrically connected to the first circuit board 40 via the second circuit board 37, and the signal transceiver 31 disposed on the second circuit board 37 can be installed at different positions in the handle shell 10 according to usage requirements.

[0071] See also Figure 1 and Figure 4 In some embodiments, the first circuit board 40 is disposed on the first side 11 of the handle shell 10, and the signal transceiver 31 is electrically connected to the first circuit board 40. Among them, the panel 20 can be disposed at any position of the handle shell 10. In the case where the panel 20 and the first circuit board 40 are respectively disposed on different sides of the handle shell 10, the signal end of the signal transceiver 31 will always correspond to the panel 20, so that the signal sent by the signal transceiver 31 or the signal that the signal transceiver 31 can receive is not blocked or shielded by the handle shell 10 as much as possible. In some embodiments, the signal transceiver 31 is mounted on the first circuit board 40 and is disposed on the side of the first circuit board 40 facing the panel 20. When the panel 20 is opposite to the first circuit board 40, the signal transceiver 31 disposed on the side of the first circuit board 40 facing the panel 20 can also be opposite to the panel 20, so that there is no obstruction from other structures of the oral care device 100 between the panel 20 and the signal transceiver 31, and the signal sent by the signal transceiver 31 or the signal sent by an external device to the signal transceiver 31 and can be received by the signal transceiver 31 can directly pass through the non-metallic panel 20, and the signal loss during transmission is less. In other embodiments, the electrical connection end of the signal transceiver 31 is disposed on either side of the first circuit board 40, and the signal end of the signal transceiver 31 can extend to a position opposite to the panel 20, so as to prevent the signal transceiver range of the signal transceiver 31 from being obstructed and / or shielded by the metal handle shell 10 or other metal structures in the oral care device 100.

[0072] Please combine Figure 3In some embodiments, the first circuit board 40 includes a first end 41 and a second end 43 opposite to each other in the direction X of the central axis A of the handle shell 10, and the first end 41 is closer to the bottom end 17 of the handle shell 10 than the second end 43. The signal transceiver 31 is installed at the second end 43 and is located closer to the bottom end 17 of the handle shell 10. When the signal transceiver 31 is arranged at the second end 43, the path length of the signal transmitted from the handle shell 10 to the panel 20 is shorter, thereby reducing the loss of the signal sent by the signal transceiver 31. At the same time, the signal transceiver 31 is arranged at a position closer to the second end 43, which can also reduce the relative distance between the signal transceiver 31 and the external device that can send the signal, so that the information transmitted by the external signal received by the signal transceiver 31 is more complete.

[0073] In the case where the main chip 35, the matching circuit 33 and the signal transceiver 31 are all arranged on the first circuit board 40, the signal transceiver 31 and the matching circuit 33 are closer to the second end 43 than the main chip 35. The matching circuit 33 is arranged between the main chip 35 and the signal transceiver 31, which can reduce the installation position occupied by the matching circuit 33 on the first circuit board 40 as much as possible, so that the electrical components on the first circuit board 40 can be installed more tightly and the layout of the electrical components on the first circuit board 40 is more reasonable. At the same time, arranging the signal transceiver 31 closer to the second end 43 can make the signal transceiver 31 correspond to the panel 20, so that the signal sent by the signal transceiver 31 or the signal received by the signal transceiver 31 can pass through the panel 20 as much as possible without being blocked by the metal handle shell 10. Arranging the signal transceiver 31 closer to the second end 43 can also prevent the user from blocking the signal transceiver path of the signal transceiver 31 when holding the oral care device 100.

[0074] See also Figure 3 and Figure 4 In some embodiments, the oral care device 100 further includes a functional device 50, which is a device capable of realizing different functions of the oral care device 100, and the functional device 50 can be electrically connected to the first circuit board 40 to perform different functions. In some embodiments, the signal transceiver 31 and the functional device 50 are both disposed on the first circuit board 40, and the signal transceiver 31 is spaced apart from the functional device 50. The matching circuit 33 is disposed on the first circuit board 40. The main chip 35 is disposed on the first circuit board 40 and spaced apart from the functional device 50 and the signal transceiver 31, and the main chip 35 is electrically connected to the functional device 50. In other embodiments, the signal transceiver 31 is not disposed on the first circuit board 40, and the main chip 35, the matching circuit 33 and the functional device 50 disposed on the first circuit board 40 are electrically connected to the signal transceiver 31 through conductive members.

[0075] Furthermore, in some embodiments, the signal transceiver 31 is disposed within a predetermined distance range of the functional device 50. Since the functional device 50 needs to be always opposite to the panel 20 to realize the function, when the distance between the functional device 50 and the signal transceiver 31 is within the predetermined distance range of the functional device 50, the signal transceiver area of ​​the signal transceiver 31 can also overlap with the panel 20 as much as possible, so that the signal is less blocked by the metal handle shell 10 or other structures of the oral care device 100. The distance between the functional device 50 and the signal transceiver 31 is the distance in three-dimensional space. That is, the distance between the two can be calculated either along the direction X of the central axis A of the handle shell 10 or along any direction perpendicular to the central axis A of the handle shell 10, and there is no limitation here.

[0076] Furthermore, in some embodiments, the functional device 50 is spaced apart from the panel 20 in the direction Y perpendicular to the central axis A of the handle housing 10. That is, there is a certain distance between the functional device 50 and the panel 20. Since some functional devices 50 have metal parts or other structures that can block signals, shield signals, or affect signal transmission, when the functional device 50 is spaced apart from the panel 20, the edge of the signal transceiver area of ​​the signal transceiver 31 disposed near the functional device 50 can be staggered with the edge of the functional device 50, so that the functional device 50 cannot block the signal transceiver area of ​​the signal transceiver 31 or reduce the blocking area of ​​the signal transceiver area by the functional device 50, and the signal transmission effect is better.

[0077] Furthermore, please combine Figure 5 In some embodiments, the second area 203 of the panel 20 is light-transmissive, and the functional device 50 can be opposite to the second area 203. The functional device 50 is opposite to the light-transmissive second area 203, so that the optical signal emitted by the functional device 50 can pass through the panel 20 to be recognized. In the case where the portion of the panel 20 opposite to the signal transceiver 31 is light-transmissive but not transparent or completely opaque, the signal transceiver 31 disposed in the handle shell 10 and opposite to the panel 20 can be partially blocked by the opaque portion of the panel 20 or the opaque first area 201, so that the appearance of the oral care device 100 is more beautiful.

[0078] Specifically, please combine Figure 6In some embodiments, the functional device 50 includes a button 51, which is generally an electrical component and / or circuit structure that can be triggered and change the operating state of the oral care device 100. The button 51 is arranged in the accommodating cavity 101 and is electrically connected to the first circuit board 40. The pressing portion 21 of the panel 20 is opposite to the button 51. When the user presses the pressing portion 21, the pressing portion 21 can trigger the button 51 to change the operating mode of the oral care device 100. The signal transceiver 31 and the button 51 are preset with a first preset distance D1 on the axis of the central axis A of the handle shell 10. The size of the first preset distance D1 is related to the signal receiving and transmitting range of the signal transceiver 31. Since the button 51 always corresponds to the panel 20, when the distance between the button 51 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is less than the first preset distance D1, the signal transceiver area of ​​the signal transceiver 31 can correspond to at least part of the structure of the panel 20, and the signal can be transmitted to the external device through the panel 20 or received by the signal transceiver 31 from the outside through the panel 20, and the signal transmission effect is better. When the distance between the button 51 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is greater than or equal to the first preset distance D1, the signal sent by the signal transceiver 31 and the signal sent from the outside to the signal transceiver 31 may be blocked.

[0079] More specifically, in some embodiments, the functional device 50 includes an indicator 53, which can indicate the current working state of the oral care device 100 by sound, light or electrical signal. The indicator 53 is disposed in the accommodating cavity 101 and is electrically connected to the first circuit board 40. In the case where the indicator 53 is a component that indicates the current working state of the oral care device 100 by light, the indicator 53 is opposite to the light-transmitting portion 23, and the light-transmitting portion 23 of the panel 20 can transmit the light emitted by the indicator 53 to the outside of the handle shell 10, and the indicator 53 is used to emit light to the outside of the handle shell 10 through the light-transmitting portion 23. The signal transceiver 31 and the indicator 53 are preset at a second preset distance D2 on the axis of the central axis A of the handle shell 10. The second preset distance D2 can be the same as or different from the first preset distance D1. Since the indicator 53 always corresponds to the light-transmitting portion 23 of the panel 20, when the distance between the indicator 53 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is less than the second preset distance D2, the signal transceiver area of ​​the signal transceiver 31 can correspond to at least part of the light-proof structure of the panel 20, and the signal can be transmitted to the external device through the panel 20 or received by the signal transceiver 31 from the outside through the panel 20, and the signal transmission effect is better. When the distance between the indicator 53 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is greater than or equal to the second preset distance D2, the signal sent by the signal transceiver 31 and the signal sent from the outside to the signal transceiver 31 may be blocked.

[0080] More specifically, in some embodiments, the functional device 50 includes a display screen 55, which is disposed in the accommodating cavity 101 and electrically connected to the first circuit board 40. The display screen 55 is opposite to the light-transmitting portion 23, and the display screen 55 is an electrical structure or electrical component that can display a picture to the outside of the handle shell 10 through the light-transmitting portion 23. The display area of ​​the display screen 55 can correspond to the light-transmitting portion 23 of the panel 20 so that the user can see the display picture on the outside of the handle shell 10, and the display screen 55 can display the current working state of the oral care device 100 and various parameters of the oral care device 100 and other information. The signal transceiver 31 and the display screen 55 are preset with a third preset distance D3 on the axis of the central axis A of the handle shell 10. The third preset distance D3, the second preset distance D2 and the first preset distance D1 can be the same or different. Since the indicator 53 always corresponds to the light-transmitting portion 23 of the panel 20, when the distance between the display screen 55 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is less than the second preset distance D2, the signal transceiver area of ​​the signal transceiver 31 can correspond to at least part of the light-proof structure of the panel 20, and the signal can be transmitted to the external device through the panel 20 or received by the signal transceiver 31 from the outside through the panel 20, and the signal transmission effect is better. When the distance between the display screen 55 and the signal transceiver 31 along the direction X of the central axis A of the handle shell 10 is greater than or equal to the second preset distance D2, the signal sent by the signal transceiver 31 and the signal sent from the outside to the signal transceiver 31 may be blocked. In particular, when the signal transceiver 31 and the display screen 55 are both opposite to the panel 20, a gap needs to be provided between the display screen 55 and the panel 20 to reduce the blocking of the display screen 55 on the signal sent by the signal transceiver 31 to the outside of the handle shell 10 and the signal sent by the external device to the signal transceiver 31.

[0081] See also Figure 3 and Figure 4In some embodiments, the oral care device 100 further includes a core assembly 60, which is a component installed in the handle shell 10 and capable of supporting and installing the first circuit board 40 and other structures of the oral care device 100. The core assembly 60 is disposed in the accommodating cavity 101. In some embodiments, the core assembly 60 is detachably mounted on the inner wall of the handle shell 10, and the mounting method includes but is not limited to threaded connection, snap connection or bolt connection. In other embodiments, the core assembly 60 is non-detachably fixed to the inner wall of the handle shell 10, and the fixing method includes but is not limited to hot melt connection, gluing connection or welding. In the case where only a part of the structure of the signal transceiver 31 is electrically connected to the first circuit board 40, a part of the structure of the signal transceiver 31 can be fixed to the core assembly 60, and the signal end of the signal transceiver 31 extends to a position opposite to the panel 20. The core assembly 60 can be used to install the signal transceiver 31. In the case where the signal transceiver 31 is a separate antenna, the signal transceiver 31 can pass through the core assembly 60, and the electrical connection end of the signal transceiver 31 can be electrically connected to the first circuit board 40 installed on the core assembly 60 and located on a different side from the panel 20. The signal end of the signal transceiver 31 can extend from the core assembly 60 or be embedded in the surface of the core assembly 60, and always keep corresponding to the panel 20, so as to prevent the signal sent by the signal end of the signal transceiver 31 or the signal received by the signal end of the signal transceiver 31 from being blocked by other structures of the oral care device 100.

[0082] Specifically, in some embodiments, along a direction Y perpendicular to the central axis A of the handle shell 10, the movement assembly 60 includes a first side and a second side that are arranged opposite to each other, the first side of the movement assembly 60 is oriented in the same direction as the first side 11 of the handle shell 10, the first circuit board 40 is fixed to the first side of the movement assembly 60, and the signal end of the signal transceiver 31 is fixed to the second side of the movement assembly 60. In the case where the signal transceiver 31 is a strip antenna and is directly connected to the first circuit board 40, in some embodiments, the electrical connection end of the signal transceiver 31 connected to the first circuit board 40 is wrapped around the surface of the movement assembly 60 to the first side 11 of the handle shell 10, and the signal end of the signal transceiver 31 opposite to the panel 20 is arranged at the second end 43 of the handle shell 10. In other embodiments, please refer to Figure 5The core assembly 60 is provided with a wire hole 63 and a wire groove 65. The wire hole 63 penetrates the outer shell of the core assembly 60 along the direction Y perpendicular to the central axis A of the handle shell 10. The wire groove 65 is provided on the second side of the core assembly 60 and extends a distance along the direction X of the central axis A of the handle shell 10. At least part of the structure of the wire groove 65 is opposite to the panel 20. The electrical connection end of the signal transceiver 31 connected to the first circuit board 40 can pass through the wire hole 63 and be connected to the first circuit board 40 at the first side 11 of the handle shell 10. The signal end of the signal transceiver 31 opposite to the panel 20 passes through the wire hole 63 and is provided in the wire groove 65 to be arranged opposite to the panel 20.

[0083] See also Figure 3 and Figure 5 In some embodiments, the oral care device 100 further includes an inner liner 70. The inner liner 70 is generally a cylindrical structure disposed in the handle shell 10 and connected to the handle shell 10. The inner liner 70 is disposed in the accommodating cavity 101 and connected to the handle shell 10. The material of the inner liner 70 includes but is not limited to non-metallic materials such as plastic, silicone or rubber. Compared with the metal handle shell 10, the inner liner 70 can be more firmly connected to the structure in the oral care device 100, reducing the shaking and collision of the internal structure in the oral care device 100. In some embodiments, the inner liner 70 can be integrally formed in the handle shell 10. In other embodiments, the inner liner 70 is a structure installed in the handle shell 10 after being separately formed. The outer contour size of the cross section of the inner liner 70 is less than or equal to the inner contour size of the cross section of the handle shell 10, so that the inner liner 70 can be installed in the handle shell 10. The core assembly 60 is disposed in the inner liner 70 and connected to the inner liner 70. Since the handle shell 10 is made of metal, the internal structure of the oral care device 100 is difficult to fix on the metal handle shell 10, and the cost of manufacturing the fixed structure in the metal handle shell 10 is high. The non-metallic liner 70 can be used to connect the internal structure of the oral care device 100, which can reduce the manufacturing cost of the oral care device 100 on the one hand, and can also prevent the internal structure of the oral care device 100 from shaking in the handle shell 10 on the other hand, thereby protecting the internal structure of the oral care device 100.

[0084] Further, in some embodiments, the liner 70 is provided with a support platform 73 at a position corresponding to the through hole 103. The support platform 73 is generally a structure protruding from the surface of the liner 70 and partially extending into the through hole 103, and the panel 20 can be installed on the support platform 73. Since the support platform 73 and the panel 20 are both made of non-metallic materials, the support platform 73 can more conveniently install the panel 20, and can also enable the panel 20 installed on the support platform 73 to be tightly combined with the metal handle shell 10.

[0085] Furthermore, in some embodiments, the lining 70 is provided with a connecting portion 71. The core assembly 60 is disposed in the lining 70 and a matching portion 61 is disposed on the core assembly 60, and the connecting portion 71 and the matching portion 61 can be matched and connected to connect the core assembly 60 with the lining 70. In some embodiments, the connecting portion 71 and the matching portion 61 can be slidably matched along the direction X of the central axis A of the handle shell 10. In other embodiments, the connecting portion 71 and the matching portion 61 can be rotationally matched around the central axis A of the handle shell 10. The connecting portion 71 of the lining 70 is disposed on the inner peripheral wall of the lining 70, and the matching portion 61 of the core assembly 60 is disposed on the outer peripheral wall of the core assembly 60. In some embodiments, the connecting portion 71 is a depression formed from the lining 70 toward the inner wall close to the handle shell 10, and the matching portion 61 is a protrusion formed from the core assembly 60 toward the inner wall close to the lining 70. In other embodiments, the connection portion 71 is a protrusion formed from the liner 70 toward the outer wall of the core assembly 60, and the matching portion 61 is a depression formed from the core assembly 60 toward the inner wall away from the liner 70.
