Description

Technical area

[0001] The present application relates to the technical field of oral hygiene and in particular to an oral care device. State of the art

[0002] An oral care device is an electrical device that uses a high-speed vibration motor to drive the brush head to rotate or vibrate, thereby cleaning teeth. Depending on the user's needs, the oral care device can be equipped with an antenna for transmitting and / or receiving external signals, sending operating information to a control terminal or the cloud, or receiving instructions sent from the terminal or cloud. However, the antenna currently installed in the oral care device must penetrate the internal structure or casing of the oral care device to transmit and / or receive signals, resulting in increased signal loss and poor transmission efficiency. Contents of this application

[0003] The present application provides an oral care device that at least solves the problem of poor signal transmission efficiency of the antenna within the oral care device.

Detailed description of the embodiments

[0009] The implementation of the present application is described in detail below. Examples of the implementation are illustrated in the accompanying drawings, in which the same or similar designations refer to the same or similar elements or elements with the same or similar functions.

They do not imply that the device or element in question must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or as implying a limitation on the number of technical features specified.Therefore, features marked "first" or "second" may explicitly or implicitly encompass one or more features. In the description of the present application, "multiple" means two or more, unless expressly and specifically limited.

[0011] In the description of the present application, it should be noted that the terms "mounted", "connected", and "coupled" are to be interpreted broadly and, in one example, may be fixedly connected, or may be detachably connected, or may be integrally connected; may be mechanically connected, or may be electrically connected, or may communicate with each other; may be directly connected, or may be indirectly connected via an intermediary; and may be an internal connection between two elements or an interaction between two elements.

[0012] With reference to Fig. 1 and Fig. 2 in conjunction with Fig. 4, an oral care device 100 of the present application comprises a handle shell 10, a circuit board 20 arranged in the handle shell 10, a communication module 30 arranged in the handle shell 10, and an electrical connection 40 arranged in the handle shell 10. The handle shell 10 is provided with a signal section 101. The communication module 30 comprises a communication module 31, wherein the communication module 31 is arranged on the circuit board 20 and electrically connected to the circuit board 20. The communication module 31 is electrically connected to the signal section 101 of the handle shell 10 via the electrical connection 40, and the signal section 101 of the handle shell 10 and the communication module 31 together form a signal transceiver, which is used for transmitting signals outside the handle shell 10 and / or for receiving signals from outside the handle shell 10.

[0013] In the oral care device 100 of the present application, after the communication module 31 is electrically connected to the signal section 101 of the handle 10, the communication module 31 and the signal section 101 of the handle 10 can together form a signal transceiver. The signals transmitted from the signal transceiver can be directly transmitted to the outside of the handle 10 via the signal section 101 of the handle 10, and the signals transmitted from external devices can be directly received by the signal section 101 of the handle 10. During signal transmission, the signals do not need to pass through the handle 10, resulting in less signal loss and better signal transmission efficiency.

[0014] With reference to Fig. 1 and Fig. 2, in some embodiments, the handle shell 10 is a housing structure that can generally accommodate a portion of the structure of the oral care device 100. A portion of the structure of the oral care device 100 can be disposed within the handle shell 10. The material of the handle shell 10 includes, but is not limited to, metal or an alloy. The communication module 31 disposed within the handle shell 10 can be electrically connected to the signal section 101 disposed on the handle shell 10 so that the current output from the communication module 31 can be converted into a signal that is directly output to the outside through the signal section 101, or the external signal received by the signal section 101 can be converted into a current that the communication module 31 can detect. In this way, the signal loss caused by the signal passing through the handle shell 10 can be reduced.

[0015] In particular, in some embodiments, the handle shell 10 includes opposite upper and lower ends. The handle shell 10 has a central axis A, wherein the central axis A of the handle shell 10 is an axis that divides the handle shell 10 into two relatively symmetrical parts. In the case where the handle shell 10 is a symmetrical three-dimensional structure, the central axis A of the handle shell 10 passes through the center of the upper end of the handle shell 10 and the center of the lower end of the handle shell 10, i.e., the direction X of the central axis A of the handle shell 10 can be either the direction of a straight line extending from the center of the upper end of the handle shell 10 to the center of the lower end of the handle shell 10, or the direction of a straight line extending from the center of the lower end of the handle shell 10 to the center of the upper end of the handle shell 10, without limitation.The direction Y perpendicular to the central axis A of the handle shell 10 can be the linear extension direction of any opposite sides of the handle shell 10, without limitation. The shape of the outer contour 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. In some embodiments, the outer contour dimensions of the cross-section of the handle shell 10 gradually change along the direction X of the central axis A of the handle shell 10 from the lower end of the handle shell 10 to the upper end of the handle shell 10. For example, the outer contour dimensions of the cross-section of the handle shell 10 initially remain unchanged and then gradually decrease, initially increase and then decrease, or change multiple times.In other embodiments, the outer contour dimension of the cross section of the handle shell 10 remains constant along the direction X of the central axis A of the handle shell 10 from the lower end of the handle shell 10 to the upper end of the handle shell 10.

[0016] In some embodiments, the handle shell 10 includes a handle tube 11 and a bottom cover 13, wherein the handle tube 11 has a substantially cylindrical structure. The handle tube 11 includes an upper end 111 (i.e., the upper end of the handle shell 10) and a lower end 113 (i.e., the lower end of the handle shell 10) opposite the upper end 111. The lower end of the handle shell 10 defines an opening, and a portion of the structure of the oral care device 100 can extend through the opening into the handle shell 10 and be mounted within the handle shell 10. The bottom cover 13 is attached to the lower end 113 of the handle tube 11 and can be arranged at the opening to seal the opening and prevent dust, moisture, liquids, or foam from outside from entering the handle tube 11 and damaging the portion of the structure of the oral care device 100 within the handle tube 11.In some embodiments, at least a portion of the structure of the handle tube 11 and the bottom cover 13 is made of metal, and the materials of the handle tube 11 and the bottom cover 13 include, but are not limited to, aluminum, iron, and their alloys. In some other embodiments, at least a portion of the structure of the handle tube 11 and the bottom cover 13 is made of non-metal, and the materials of the handle tube 11 and the bottom cover 13 include, but are not limited to, plastics, silicone, or rubber.

[0017] Furthermore, in some embodiments, in combination with Fig. 3, the signal section 101 is a region capable of converting high-frequency current or guided waves emitted by the communication module 31 into radio waves or free electromagnetic waves and radiating them into the surrounding space to generate a large radiation field. The signal section 101 is further capable of receiving radio waves or free electromagnetic waves transmitted from an external terminal or the cloud, etc., and converting them into current or guided waves that can be detected by the communication module 31. In some embodiments, the signal section 101 comprises antenna material. The antenna material can be, for example, metal, ceramic, or fiberglass. By using antenna material, the signal emitted by the signal section 101 can be transmitted over a greater distance and with greater stability than with other conductor materials.In addition, the signal section 101 is capable of receiving a wider range of signals and extracting more comprehensive information from the received signals.

[0018] With reference to Fig. 4 and Fig. 6, in some embodiments, the signal section 101 is arranged on the bottom cover 13, as in Fig. 2; one end of the electrical connection 40 is electrically connected to the communication module 31 to transmit power or guided waves, and the other end of the electrical connection 40 is applied to the signal section 101 on the bottom cover 13 to transmit power or guided waves to the signal section 101 on the bottom cover 13. When the signal section 101 is arranged on the bottom cover 13, signals can be directly transmitted to the outside via the signal section 101 on the bottom cover 13, or signals from external devices can be received via the signal section 101 on the bottom cover 13.In this case, the signal reception and transmission area corresponding to the signal section 101 can all be arranged within the area where the bottom cover 13 is located to reduce the impact of the structure of the oral care device 100 on the signal reception and transmission function of the antenna and ensure the signal transmission quality and signal strength. In some other embodiments, as shown in FIG. Fig. 1, the signal section 101 is arranged on the handle tube 11; one end of the electrical connection 40 is electrically connected to the communication module 31 for transmitting power or guided waves, and the other end of the electrical connection 40 is in contact with the signal section 101 on the handle tube 11 for transmitting power or guided waves to the signal section 101 on the handle tube 11. When the signal section 101 is arranged on the handle tube 11, the signal section 101 can be arranged at any position on the handle tube 11, and the electrical connection 40 can be a wire located in the handle tube 11 and capable of connecting the communication module 31 on the circuit board 20 to the signal section 101.Furthermore, the signal section 101, located at any position on the handle tube 11, can further transmit signals in different directions or receive external signals from different directions, and the bandwidth of the signal section 101 that receives or transmits signals is larger. In some embodiments, as shown in FIGS. Fig. 7 and Fig. 8, at least two signal sections 101 are arranged, and the at least two signal sections 101 can be arranged on the bottom cover 13 and the handle tube 11, respectively, in order to increase the signal transmission range of the oral care device 100.

[0019] With reference to Fig. 6, in some embodiments, the handle shell 10 further includes a non-signal portion 103, which is a part of the structure that is not capable of receiving signals or transmitting signals to the outside. The non-signal portion 103 may be in contact with the signal portion 101 or insulated from the signal portion 101. The non-signal portion 103 may be disposed either on the handle tube 11 or on the base cover 13. In some embodiments, the non-signal portion 103 may comprise a material that is electrically insulated from the signal portion 101. In other embodiments, the non-signal portion 103 may be electrically connected to the signal portion 101 to perform various functions. For example, the non-signal portion 103 is an electrical trigger button that can control the opening or closing of the oral care device 100 when power is detected in the non-signal portion 103. Preferably, as in Fig. 8, the material of the non-signal section 103 is generally different from the material of the signal section 101. When the material of the non-signal section 103 is different from the material of the signal section 101, there is no mutual interference between the non-signal section 103 and the signal section 101, thereby avoiding the occurrence of turbulence and affecting the quality of signal transmission.

[0020] Specifically, in some embodiments, when the grip shell 10 is made of an all-metal material, both the signal portion 101 and the non-signal portion 103 are made of a metal material, and the metal material of the signal portion 101 is different from the metal material of the non-signal portion 103. When the signal portion 101 and the non-signal portion 103 are both made of metal, the non-signal portion 103 may be an ordinary conductor material that cannot mutually convert high-frequency current and radio waves. Therefore, there is no mutual interference between the non-signal portion 103 and the signal portion 101, and the signal transmission quality can also be prevented from being degraded after the occurrence of turbulence.

[0021] With reference to Fig. 6, in some embodiments, along the direction X of the central axis A of the handle shell 10, the distance H1 between the signal portion 101 and the upper end 111 of the handle tube 11 is no more than 1 / 4 of the total length H0 of the handle shell 10. If the signal portion 101 is attached to a position where the distance H1 between the signal portion 101 and the upper end 111 of the handle tube 11 is less than 1 / 4 of the total length H0 of the handle shell 10, the signal portion 101 may be attached to a side of the handle shell 10 that is closer to the upper end 111 of the handle tube 11. In this case, the signal portion 101 is arranged on the peripheral wall of the handle tube 11, and the signal portion 101 is arranged relative to the handle tube 11 on a side that is closer to the upper end 111 of the handle tube 11.When the signal portion 101 is located on the side of the handle shell 10 closer to the upper end 111 of the handle tube 11, the signal portion 101 can be offset from a position where the user holds the oral care device 100 and prevent the user from blocking the signal transmission path of the signal portion 101 when holding the oral care device 100. In some other embodiments, the distance H2 between the signal section 101 and the lower end 113 of the handle tube 11 in the direction X along the central axis A of the handle shell 10 does not exceed 1 / 4 of the total length H0 of the handle shell 10. If the signal section 101 is attached at a position where the distance H2 between the signal section 101 and the lower end 113 of the handle tube 11 is less than 1 / 4 of the total length H0 of the handle shell 10, the signal section 101 can be arranged on a side of the handle shell 10 that is closer to the lower end 113 of the handle tube 11.In this case, the signal portion 101 is disposed on the bottom cover 13, and the signal portion 101 is disposed on a side closer to the lower end 113 of the handle tube 11 relative to the handle shell 10. When the signal portion 101 is disposed on the side of the handle shell 10 closer to the lower end 113 of the handle tube 11, the signal portion 101 can be offset from a position where the user holds the oral care device 100, preventing the user from blocking the signal transmission path of the signal portion 101 when holding the oral care device 100.

[0022] Furthermore, in some embodiments, the bottom cover 13 includes a metallic insertion part 131 and a non-metallic connecting part 133. The insertion part 131 extends into the handle tube 11 from a side of the connecting part 133 adjacent to the lower end 113 of the handle tube 11, and the connecting part 133 is connected to the insertion part 131 and disposed in the handle tube 11. The sealing portion 131 is substantially plate-shaped, and the sealing portion 131 can seal the opening of the lower end 113 of the handle tube 11 to isolate the internal structure of the oral care device 100 from the outside and prevent moisture or dust from entering the oral care device 100.The connecting part 133 can be connected to the handle tube 11 and prevent the handle tube 11 from detaching from the bottom cover 13, thereby improving the stability of the electrical connection between the electrical connection 40 and the signal portion 101 on the plug-in part 131. In some embodiments, the connecting part 133 is essentially a hook structure or plate structure that extends into the handle tube 11 and can be connected to the handle tube 11 so that the bottom cover 13 can be mounted on the handle tube 11. In some other embodiments, the connecting part 133 is essentially a tubular structure with an internal cavity. The signal portion 101 is arranged on the plug-in part 131, the electrical connection 40 abuts the signal portion 101 on the plug-in part 131, and the connecting part 133 can bypass the signal portion 101 on the plug-in part 131.Since the non-metallic connecting part 133 has poor electrical conductivity, the electrical connection 40 must pass through or bypass the connecting part 133 when electrically connecting to the signal section 101 on the plug-in part 131 in order to improve the quality of signal transmission.

[0023] In particular, with regard to Fig. 4 In some embodiments, the bottom cover 13 is provided with a protruding and elongated contact tab 1301, and the contact tab 1301 is a conductive structure extending from the bottom cover 13. In some embodiments, the contact tab 1301 extends through or around the connecting part 133 to connect directly to the plug-in part 131, and the signal section 101 includes at least part of the structure of the contact tab 1301 and the plug-in part 131. In other embodiments, the contact tab 1301 is connected to the connecting part 133, and the signal section 101 includes only the contact tab 1301. One end of the electrical connection 40 is electrically connected to the communication module 31, and the other end of the electrical connection 40 abuts the contact tab 1301.Compared with the signal portion 101 on the bottom cover 13, the contact tab 1301 can be arranged closer to the electrical connection 40, so that the electrical connection 40 does not have to travel a long distance to be electrically connected to the bottom cover 13 via the contact tab 1301, and the electrical contact between the two is of better quality and the signal transmission is more stable.

[0024] With reference to Fig. 2 and Fig. 4 and in connection with Fig. 1, in some embodiments, the communication assembly 30 is generally configured to be capable of transmitting a signal in response to a command, or receiving and reading a signal transmitted from an external device to the oral care device 100 to receive a command. The type of communication assembly 30 includes, but is not limited to, a Wi-Fi module, a Bluetooth module, or Zigbee, etc. The circuit board 20 is configured to be electrically connected to the communication assembly 30 to supply power to the communication assembly 30. In some embodiments, the communication module 31 of the communication assembly 30 is disposed on the circuit board 20 and directly electrically connected to the circuit board 20. In other embodiments, as in Fig. As shown in Figure 10, the communication module 31 is disposed on the signal portion 101 of the handle shell 10 (located on the handle tube 11 or the bottom cover 13) and indirectly electrically connected to the circuit board 20. The communication module 31 is capable of transmitting power or a guided wave to the signal portion 101 or receiving power or a guided wave transmitted from the signal portion 101 via the electrical connection 40, so as to achieve the function of transmitting signals from the oral care device 100 or receiving signals sent from external terminals or the cloud.

[0025] With reference to Fig. 2 and Fig. 4 and in connection with Fig. 1, the electrical connection 40 is configured in some embodiments to electrically connect the communication module 31 and the signal section 101, or to electrically connect the circuit board 20, the communication module 31, and the signal section 101. The electrical connection 40 may, without limitation, be either a separate electrically conductive part, such as a wire (as in Fig. 7), or a rigid circuit board 20 or a flexible circuit board 20 connected to the communication module 31 or the signal section 101 (as shown in Fig. 8). The electrical connection 40 includes a first end and a second end that are opposite each other. The first end 41 of the electrical connection 40 is electrically connected to the communication module 31, and the second end 43 of the electrical connection 40 is electrically connected to the signal portion 101 of the handle shell 10.

[0026] With reference to Fig. 5, in some embodiments, the second end 43 of the electrical connection 40 is electrically connected to the inner wall of the signal section 101 of the handle shell 10 by welding, in particular copper welding, preferably copper leak welding, or lamination. In this case, the second end 43 of the electrical connection 40 is firmly connected to the inner wall of the signal section 101 of the handle shell 10 in a manner that is non-detachable, and the electrical connection 40 and the signal section 101 are always in a stable electrical connection state. On the one hand, the electrical connection 40 cannot be easily detached from the inner wall of the signal section 101, and on the other hand, the electrical connection between the two is more stable and is not interrupted. In some other embodiments, the electrical connection 40 is an elastic element, such as a spring or a spring pin.The first end 41 of the electrical connection 40 is attached to the circuit board 20 and can be electrically connected to the communication module 31, and the second end 43 of the electrical connection 40 forms an electrical contact connection with the inner wall of the signal section 101 of the handle shell 10. In this case, the second end 43 of the electrical connection 40 is in a separable and removable connection with the inner wall of the signal section 101 of the handle shell 10. The elastic electrical connection 40 can be deformed or micro-varied between the circuit board 20 and the communication module 31 and abut the communication module 31, so that the connection between the electrical connection 40 and the communication module 31 is more stable and less susceptible to circuit breaks or poor contact.

[0027] With reference to Fig. 2 and Fig. 3, in some embodiments, the oral care device 100 further includes a liner 50. The liner 50 is generally a cylindrical structure disposed within and connected to the handle tube 11. The liner 50 is made of non-metallic materials such as plastic, silicone, or rubber. Compared to the metal tube 11, the liner 50 can be more securely connected to the structure within the oral care device 100, thereby reducing shaking and collision of the structure within the oral care device 100. In some embodiments, the liner 50 can be integrally formed within the handle tube 11. In some other embodiments, the liner 50 is a structure that is separately formed and then incorporated into the handle tube 11.The outer contour dimensions of the cross-section of the liner 50 are smaller than or equal to the inner contour dimensions of the cross-section of the handle tube 11, so that the liner 50 can be installed into the handle tube 11. Since the handle tube 11 is made of metal, it is difficult to attach the structure within the oral care device 100 to the metallic handle tube 11, and it is costly to manufacture a fastening structure within the metallic handle tube 11. The non-metallic liner 50 can be used to connect the structure within the oral care device 100 to the connecting part 133 of the bottom cover 13. This reduces the manufacturing cost of the oral care device 100 and prevents the structure within the oral care device 100 from moving within the handle tube 11, thereby protecting the structure within the oral care device 100.

[0028] With reference to Fig. 4, in some embodiments, the connecting portion 133 of the bottom cover 13 is connected to the liner 50, and the non-metallic liner 50 can also be securely connected to the non-metallic connecting portion 133 so that the bottom cover 13 can be firmly connected to the metal handle tube 11. The materials of the connecting portion 133 and the liner 50 can be the same or different. The connecting portion 133 and the liner 50 can be connected in a non-removable manner, such as by fusion or adhesive bonding, or in a removable manner, such as by screwing, clamping, or bolting, without limitation. In some embodiments, the bottom cover 13 is connected to the handle tube 11. In one example, the connecting portion 133 of the bottom cover 13 extends into the handle tube 11 and is connected to both the handle tube 11 and the liner 50.In another example, the connecting part 133 of the bottom cover 13 is only connected to the handle tube 11 and separated from the liner 50.

[0029] With reference to Fig. 1 and Fig. 2 and in connection with Fig. 4, in some embodiments, the oral care device 100 further includes a movement assembly 60, wherein the movement assembly 60 is a component mounted within the handle shell 10 and capable of supporting and mounting the circuit board 20 and other structures of the oral care device 100. The movement assembly 60 is disposed within the handle shell 10, and in some embodiments, the movement assembly 60 is removably attached to an interior wall of the handle shell 10, wherein the mounting method includes, but is not limited to, a threaded connection, a snap connection, or a bolt connection. In some other embodiments, the movement assembly 60 is non-removably attached to an interior wall of the handle shell 10, wherein the mounting method includes, but is not limited to, a hot-melt connection, an adhesive connection, or a weld connection.In some embodiments, only a portion of the communication module 31 is electrically connected to the circuit board 20, and that portion of the communication module 31 may be attached to the motion assembly 60. The motion assembly 60 may be used to mount the communication module 31.

[0030] Furthermore, in some embodiments, as in Fig.As shown in Figure 9, the movement assembly 60 is disposed in and connected to the liner 50, and the electrical connection 40 extends through and / or around the liner 50 to contact the signal portion 101. The signal portion 101 can be disposed on the bottom cover 13 or the handle tube 11 without limitation. In a case where the inner peripheral wall of the liner 50 and the outer peripheral wall of the movement assembly 60 are combined with each other, the movement assembly 60 can be mounted in the liner 50, and the movement assembly 60 will not vibrate or rotate violently in the liner 50, which improves the stability of the connection between the structures in the oral care device 100.Since the liner 50 and the housing of the motion assembly 60 are both made of non-conductive, non-metallic materials, the electrical connection 40 must be routed through and / or around the liner 50 and the housing of the motion assembly 60 so that the communication module 31 can always be electrically connected to the signal section 101.

[0031] In particular, in some embodiments, the circuit board 20 further comprises a protrusion 21, which is part of the structure formed by the circuit board 20 and extends along the direction X of the central axis A of the handle shell 10 toward the base cover 13. The protrusion 21 protrudes toward the base cover 13 relative to the movement assembly 60, i.e., the protrusion 21 and the movement assembly 60 are offset from one another and do not overlap along the direction Y perpendicular to the central axis A of the handle shell 10. The communication module 31 and the electrical connection 40 are arranged on the protrusion 21.Compared to a variant without a projection 21 on the circuit board 20, the communication module 31 and the electrical connection 40 on the projection 21 can be offset from the movement assembly 60, so that the communication module 31 and the electrical connection 40 can run partially around the movement assembly 60 and can be located closer to the signal section 101 on the base cover 13 and / or the signal section 101 on the peripheral wall of the handle tube 11.On the one hand, this prevents the movement assembly 60 from obstructing the signal transmission path of the signal transceiver for receiving signals and / or transmitting signals, and on the other hand, the protrusion 21 extending toward the bottom cover 13 is further used to bring the communication module 31 and the electrical connection 40 disposed on the protrusion 21 closer to the signal portion 101, thereby improving the efficiency of signal transmission while densely arranging the internal structure of the oral care device 100.

[0032] In summary, in the oral care device 100 of the present application, after the communication module 31 is electrically connected to the signal section 101 of the handle shell 10, the communication module 31 and the signal section 101 of the handle shell 10 can together form a signal transceiver. The signals transmitted from the signal transceiver can be directly transmitted to the outside of the handle shell 10 via the signal section 101 of the handle shell 10, and the signals transmitted from external devices can also be directly received by the signal section 101 of the handle shell 10. During signal transmission, the signals do not need to pass through the handle shell 10, resulting in less signal loss and better signal transmission efficiency.
