Please refer to fig. 10 in conjunction with fig. 2. Fig. 10 is an enlarged partial view of the handle shown in fig. 3 in the region C. The side wall of the hollow protective shell 111 is provided with an accommodating space 111 a. The hollow protective shell 111 further includes a supporting portion 111b extending from a peripheral sidewall of the receiving space 111a to a center of the receiving space 111 a. The handle 110 also includes a first light transmissive cover 130. The first transparent cover 130 is carried on the carrying portion 111 b. The first light-transmitting cover 130 is disposed on a side of the first display screen 112 for displaying. The carrying part 111b has a protrusion 111c on one side close to the first light-transmitting cover plate 130. The protrusion 111c surrounds the sidewall of the receiving space 111 a. The protrusion 111c is used for carrying the first light-transmitting cover plate 130.
In the above embodiment, the handle 110 may further include a first light-transmitting cover 130, and the side wall of the hollow protective shell 111 may be provided with an accommodating space 111 a. The first light-transmitting cover plate 130 is accommodated in the accommodating space 111a, and the first light-transmitting cover plate 130 is disposed on a side of the first display screen 112 for displaying. The circumferential side wall of the accommodating space 111a is further connected with a bearing part 111b, and the bearing part 111b protrudes out of the circumferential side wall of the accommodating space 111 a. A protrusion 111c surrounding the circumferential sidewall of the accommodating space 111a is disposed on one side of the carrying portion 111b close to the first transparent cover plate 130, and the first transparent cover plate 130 is carried on the protrusion 111 c.
It is understood that the first light-transmissive cover plate 130 and the carrier portion 111b may be adhered by glue. On the premise that the protrusion 111c is not provided, when the first light-transmitting cover plate 130 is adhered to the bearing portion 111b by using glue, the glue is squeezed by the first light-transmitting cover plate 130 and the bearing portion 111b to generate a glue climbing phenomenon, where the glue extends in a direction away from a portion where the first light-transmitting cover plate 130 and the bearing portion 111b generate the squeezing action, and the extended glue may affect normal operation of other electronic devices. It can be understood that, when the bearing portion 111b is provided with the protrusion 111c, the protrusion 111c can block the glue from leaking, so that the glue-climbing phenomenon can be avoided or reduced. Meanwhile, the protrusion 111c and the formed glue may also prevent or reduce the problem of external liquid from penetrating into the inside of the handle 110. From another aspect, the yield of the product can be improved by the arrangement mode.
Please refer to fig. 11 in conjunction with fig. 10. Fig. 11 is a three-dimensional perspective view of a first light-transmitting cover plate according to an embodiment of the present application. The side of the first light-transmitting cover plate 130 away from the first display screen 112 is an arc surface 131.
It can be understood that the first transparent cover 130 can transmit light, and when the first display screen 112 plays a picture, a user can see the picture from a side of the first transparent cover 130 away from the first display screen 112. The light emitted from the first display screen 112 is transmitted around, and when the light enters the air through the side of the first transparent cover 130 away from the first display screen 112, the light is reflected and refracted, and then received by human eyes. In this embodiment, the side of the first light-transmitting cover plate 130 away from the first display screen 112 is an arc 131, and when the light emitted by the first display screen 112 passes through the arc 131, the light can be refracted into a larger area range, so that a user can more easily see a picture displayed by the first display screen 112. Of course, in other embodiments, one side of the first light-transmitting cover 130 close to the first display screen 112 may be provided as an arc 131, or two opposite sides of the first light-transmitting cover 130 may be provided as the arc 131 at the same time.
Please refer to fig. 12 to 13. Fig. 12 is a schematic structural view of a handle provided in an embodiment of the present application, and fig. 13 is an enlarged partial view of a region B of the handle shown in fig. 3 provided in yet another embodiment. The handle 110 also includes a second light transmissive cover plate 140. The second transparent cover plate 140 is embedded in the sidewall of the hollow protective shell 111. The second transparent cover 140 is disposed on a side of the second display screen 113 for displaying. The second transparent cover 140 is provided with a power key 141. The handle 110 also includes an indicator light 118 e. The indicator 118e is disposed inside the handle 110 corresponding to the power key 141.
In this embodiment, the handle 110 may further include a second light-transmissive cover plate 140 embedded in the hollow protective shell 111. The second transparent cover plate 140 may be provided with a power key 141, and the power key 141 may be integrally formed on the second transparent cover plate 140. The handle 110 further includes an indicator 118e, and the indicator 118e is disposed inside the handle 110 corresponding to the power key 141. Alternatively, the indicator lamp 118e may be provided on the third circuit board 118. It is understood that the indicator light 118e can emit light, and the user can quickly find the power key 141 according to the light.
Please continue to refer to fig. 14. Fig. 14 is a schematic diagram of an electrical connection relationship between an indicator light, a control chip, and a motion sensor according to an embodiment of the present disclosure. In one embodiment, the handle 110 may further include a control chip 118f and a motion sensor 118 g. The indicator light 118e and the motion sensor 118g are electrically connected to the control chip 118 f. The motion sensor 118g may sense a shaking state of the handle 110 and generate a corresponding shaking signal, and the control chip 118f may respond to the shaking signal and generate a control signal for controlling the indicator light 118e to turn on or off, and the indicator light 118e may turn on or off according to the control signal. For example, when the handle 110 is touched by the user, the motion sensor 118g senses the shaking state of the handle 110, the control chip 118f controls the indicator light 118e to be turned on, and the user finds the power key 141 according to the light emitted by the indicator light 118 e. When the control chip 118f continuously receives the shaking signal of the motion sensor 118g, it is determined that the user is brushing teeth, and the control chip 118f controls the indicator light 118e to turn off.

When one end of the electric toothbrush 10 is inserted into the accommodating space 200 of the charging seat assembly 20, the charging transmitting coil and the charging receiving coil are close to each other, and the charging transmitting coil generates a certain current in the charging receiving coil through electromagnetic induction based on an alternating current with a certain frequency, so that point energy is transferred from the charging seat assembly 20 to the electric toothbrush 10, and the electric toothbrush 10 is charged from the charging seat assembly 20 to the mobile phone.
In other embodiments, the charging stand assembly 20 charges the electric toothbrush 10 in the form of a wired charge. The wired charging means that a power socket is provided on the electric toothbrush 10, and a power plug is provided in the accommodating space 200 of the charging stand assembly 20. When the electric toothbrush 10 is placed in the accommodating space 200, a power plug is connected to a power socket, so that the electric toothbrush 10 is electrically connected to the charging stand assembly 20 and can be charged.
The principle and the implementation of the present application are explained herein by applying specific examples, and the above description of the embodiments is only used to help understand the core idea of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
