[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0055] See also Figure 1-Figure 2 The present application proposes an electric toothbrush 100. In an embodiment of the present application, the electric toothbrush 100 includes a handle barrel 10, a movement 30 disposed in the handle barrel 10, and a brush head 50 transmission-connected to the movement 30.
[0056] See also Figure 2-Figure 3 The handle tube 10 is a cylindrical structure, and as an appearance component of the electric toothbrush 100, the handle tube 10 is suitable for being held by a user to facilitate the user to use the electric toothbrush 100. At the same time, the handle tube 10 can also protect the movement 30 disposed in the handle tube 10.
[0057] See also Figure 4 The movement 30 is used as a power component to realize the brushing function of the electric toothbrush 100. The movement 30 may include a bracket 34, a circuit board 35, a battery 39, and a motor 37. The bracket 34 is used to support the circuit board 35, the battery 39, the motor 37, and other structures. The battery 39 is used to supply power to the motor 37 and the circuit board 35. The circuit board 35 is used to control the operation of the motor 37. The output shaft of the motor 37 is connected to the brush head 50. In actual use, the high-frequency vibration energy of the motor 37 when working is transmitted to the brush head 50 through the output shaft, so that when the brush head 50 acts on the user's oral cavity, the cleaning function of the user's oral cavity can be realized.
[0058] See also Figure 4-Figure 5In some embodiments, the electric toothbrush 100 also has a display function, which can provide prompts or guidance to the user during the brushing process. Correspondingly, the movement 30 further includes a light-emitting component 33. The light-emitting component 33 may include a display screen or a lamp bead (not shown in the figure). The light-emitting component 33 is electrically connected to the circuit board 35. Under the control of the circuit board 35, the light-emitting component 33 emits corresponding light when working, and the light is transmitted outside the handle tube 10 and seen by the user, thereby realizing the display function.
[0059] In addition, the electric toothbrush 100 also has a control function, and the user can control the start and stop of the motor 37 or the operating frequency of the motor 37 during the brushing process. Correspondingly, the movement 30 further includes a detection member 31, and the detection member 31 may include a contact detection member or a non-contact detection member. The detection member 31 is electrically connected to the circuit board 35, and the detection signal of the detection member 31 can be sent to the circuit board 35. The circuit board 35 controls the motor 37 based on the detection signal to realize the start and stop of the motor 37 or the change of the operating frequency, thereby realizing the control function.
[0060] Please continue reading Figure 4-Figure 5 In order to make the handle tube 10 light-transmissive and enable the user to control the detection member 31, the handle tube 10 may include a main shell 11 and an interactive shell 13 that are connected to each other, and the interactive shell 13 can be used to realize the interaction between the user and the electric toothbrush 100.
[0061] See also Figure 5-Figure 6 Specifically, the interactive shell 13 may include a light-transmitting portion 131 and a button portion 133, wherein the light-emitting element 33 is arranged corresponding to the light-transmitting portion 131, so that the light-emitting element 33 can transmit light to the outside of the handle tube 10 through the light-transmitting portion 131. In this way, the light emitted by the light-emitting element 33 can be transmitted through the light-transmitting portion 131 to realize the display function.
[0062] The detection member 31 is arranged corresponding to the button portion 133 so that the detection member 31 can detect that the button portion 133 is pressed or touched to realize the control function. For example, when the detection member 31 is in the form of a contact detection member, the user can press the button portion 133 so that the button portion 133 contacts the detection member 31 and triggers the corresponding control function; for another example, when the detection member 31 is in the form of a non-contact detection member, the user can touch the button portion 133, and the detection member 31 can detect the specific parameters on the button portion 133 so that the detection member 31 can detect that the button portion 133 is touched by the user and trigger the corresponding control function.
[0063] In some embodiments, on the basis that the detection member 31 is in the form of a contact detection member, the detection member 31 may include a pressure switch or a button. When the detection member 31 is a pressure switch, the button portion 133 is configured to deform and press the pressure switch, so that the user can trigger the pressure switch by pressing the button portion 133; it is understood that the pressure switch has a faster response speed to improve the user's fluency in the process of controlling the motor 37 by pressing the button portion 133, and the pressure switch also has a higher reliability, which can ensure long-term and relatively stable operation. When the detection member 31 is a button, the button portion 133 is configured to trigger the button by deforming and abutting the button; it is understood that there will be a clear sense of abutment during the triggering process of the button portion 133 deforming and abutting the button, which can provide the user with clearer operational feedback and improve the user's experience, and the button also has a higher mechanical reliability and stability, which can ensure long-term and relatively stable operation, and the cost of the button is low, which effectively reduces the manufacturing cost of the electric toothbrush 100.
[0064] In other embodiments, on the basis that the detection element 31 is a non-contact detection element, the detection element 31 may include a light detection element, a sound wave detection element, or a temperature detection element. When the detection element 31 is a light detection element, the position of the button portion 133 is transparent, and when the user touches the button portion 133, the user's hand will block the position of the button portion 133, so that the light detection element can detect the luminous flux at the button portion 133, and detect whether the user touches the button portion 133 by the change of the actual luminous flux.
[0065] When the detection element 31 is an acoustic wave detection element, the user's hand is located at the position of the button part 133 and reflects the acoustic wave signal emitted by the acoustic wave detection element, so that the acoustic wave detection element can detect whether the user touches the button part 133 by detecting the acoustic wave signal reflected at the button part 133.
[0066] When the detection element 31 is a temperature detection element, when the user's hand touches the button part 133, heat exchange will occur between the button part 133 and the hand, so that the temperature on the button part 133 changes. Therefore, the temperature detection element can detect whether the user touches the button part 133 by detecting the temperature signal on the button part 133.
[0067] Based on the settings of the above three forms of non-contact detection components, the detection component 31 can detect whether the button part 133 is touched by the user without physical contact between the button part 133 and the detection component 31. Therefore, the detection component 31 will not be worn due to the physical contact between the button part 133 and the detection component 31, which effectively extends the service life of the detection component 31 and avoids the situation where the button part 133 is deformed or damaged due to the user pressing the button part 133 multiple times, thereby extending the service life of the button part 133. In addition, the user only needs to lightly touch the button part 133 to realize the control function, which is also more convenient for user operation.
[0068] The following content still takes the detection member 31 as a contact detection member, and the button part 133 triggers the detection member 31 by abutting or pressing the detection member 31, and further elaborates on the fact that the handle tube 10 of the electric toothbrush 100 of the present application has a simple manufacturing process and can effectively improve the production efficiency of the electric toothbrush 100 in the workshop.
[0069] Please continue reading Figure 5-Figure 6 , further, the interactive shell 13 is an integrally formed component. For example, the interactive shell 13 is made of plastic material or plastic material, and in the actual production process, the interactive shell 13 including the light-transmitting portion 131 and the button portion 133 can be formed at one time by injection molding, and the light-transmitting portion 131 and the button portion 133 are made of the same material. Based on this, on the basis that the electric toothbrush 100 has interactive functions such as display function and control function, it also has the following technical effects:
[0070] Since the interactive shell 13 is an integrally formed component, in the actual production process, the interactive shell 13 including the light-transmitting portion 131 and the button portion 133, which are made of the same material, can be formed in one-time molding, and then the interactive shell 13 is connected to the main shell 11, for example, the interactive shell 13 and the main shell 11 are subjected to secondary injection molding, so that the main shell 11 and the handle tube 10 can be stably connected in two steps. Compared with the related art, which first separately molds the light-transmitting portion 131 or the button portion 133 of different materials, then molds the two into one by secondary injection molding and other processes, and then connects the interactive shell 13 to the main shell 11 in three steps, the handle tube 10 of the present application has simpler steps in terms of process manufacturing, which is convenient for the production of the interactive shell 13 and the main shell 22, and greatly improves the production efficiency of the workshop.
[0071] In addition, on the basis that the interactive shell 13 is an integrally formed component, not only can the overall strength of the interactive shell 13 be increased and the overall integrity of the interactive shell 13 be maintained, so that the interactive shell 13 is not easily deformed or damaged when subjected to external force, but also the side wall of the light-transmitting portion 131 and the side wall of the button portion 133 can be seamlessly connected, thereby solving the problem that when there is a gap between the side wall of the light-transmitting portion 131 and the side wall of the button portion 133, the gap will harbor dirt.
[0072] See also Figure 6 In some embodiments, the interactive shell 13 and the main shell 11 are separate structures, and the interactive shell 13 is connected to the main shell 11 by at least one connection method selected from bonding, clamping, and interference fit. In this way, the interactive shell 13 and the main shell 11 can be separately molded, and then the interactive shell 13 can be connected to the main shell 11, so that the interactive shell 13 and the main shell 11 can be flexibly manufactured separately.
[0073] See also Figure 7-Figure 9 In other embodiments, the interactive shell 13 is formed as one body with the main shell 11, so that the interactive shell 13 is seamlessly connected to the main shell 11. For example, the interactive shell 13 is a plastic part or a plastic part, and can be formed as one body with the main shell 11 through an injection molding process, so as to be seamlessly connected to the main shell 11, thereby avoiding the problem of a connection seam between the interactive shell 13 and the main shell 11, which may cause leakage or dirt in the connection seam.
[0074] See also Figure 10-11 In some embodiments, the outer surface 1313 of the light-transmitting portion 131 is an arc surface that is convex relative to the outer surface 1333 of the button portion 133 in a direction away from the light-emitting member 33. In this way, compared with the outer surface 1313 of the light-transmitting portion 131 being an arc surface that is concave relative to the outer surface 1333 of the button portion 133 in a direction close to the light-emitting member 33, or the outer surface 1313 of the light-transmitting portion 131 being a plane, the form of the outer surface 1313 of the light-transmitting portion 131 in the embodiment of the present application can increase the observation angle, that is, the viewing angle of the light-transmitting portion 131 is larger, so that the user can observe the outer surface 1313 of the light-transmitting portion 131 at different holding angles, thereby improving the user's experience. Optionally, the outer surface 1313 of the light-transmitting portion 131 can also be a plane or an arc surface that is concave in a direction close to the light-emitting member 33, and the embodiment of the present application does not limit this.
[0075] See also Figure 7-Figure 9Furthermore, the outer surface 1313 of the light-transmitting portion 131 has a first curvature, and the main housing 11 has a front surface 1113 located on the same side as the interactive shell 13, and the front surface 1113 has a second curvature. The first curvature is smaller than the second curvature. In this way, the outer surface 1313 of the light-transmitting portion 131 is less curved and smoother than the front surface 1113, so that the light is less refracted and scattered when passing through the outer surface 1313 of the light-transmitting portion 131, effectively reducing the degree of deformation of the light, thereby improving the display effect of the light-emitting element 33. In addition, when the first curvature is smaller than the second curvature, in the radial direction of the handle tube 10 and in the direction away from the inside of the handle tube 10, the height of the outer surface 1313 of the light-transmitting portion 131 will be lower than the height of the front surface 1113, so that when the electric toothbrush 100 accidentally falls, there is a greater probability that the main shell 11 will collide with the ground first, thereby reducing the probability of the outer surface 1313 of the light-transmitting portion 131 colliding with the ground, extending the life of the interactive shell 13, and reducing the risk of scratches on the light-transmitting portion 131 of the interactive shell 13. In other embodiments, the first curvature can also be equivalent to the second curvature, so that the overall appearance consistency of the outer surface 1313 of the light-transmitting portion 131 and the front surface 1113 is better, or the first curvature is greater than the second curvature, and the embodiment of the present application is not limited to this.
[0076] See also Figure 6-Figure 8 In some embodiments, the interactive shell 13 is a hard light-transmitting plastic part, the main shell 11 has an installation opening 1111 for installing the interactive shell 13, and the outer peripheral wall of the interactive shell 13 is connected to the mouth wall of the installation opening 1111 to cover the installation opening 1111. In this way, on the basis of the interactive shell 13 being a hard light-transmitting plastic part, the interactive shell 13 has better strength itself, so as to be suitable for the scenario where the user presses the button part 133 of the interactive shell 13 multiple times. Since the interactive shell 13 has better strength itself, it is not easy to deform when subjected to force, which can reduce the possibility of cracking of the interactive shell 13; the light-transmitting part 131 of the interactive shell 13 is not easy to be scratched, and the light-transmitting part 131 can maintain a better display effect under long-term use.
[0077] See also Figure 10-11In some embodiments, the button portion 133 has a first thickness H1 in the radial direction of the handle tube 10, and the light-transmitting portion 131 has a second thickness H2 in the radial direction of the handle tube 10. The first thickness H1 is greater than the second thickness H2. It can be understood that in actual use, the user needs to press the button portion 133 to achieve the control function, so the force application position of the user's hand in the interactive shell 13 mainly falls on the position of the button portion 133. Based on this, by setting the first thickness H1 to be greater than the second thickness H2, the structural strength of the button portion 133 is better, so as to be suitable for the scene where the button portion 133 needs to be pressed by the user multiple times. In other embodiments, the first thickness H1 can also be equal to or less than the second thickness H2, and the embodiments of the present application are not limited to this.
[0078] See also Figure 6-Figure 11 Furthermore, the outer surface 1333 of the button portion 133 includes a pressing area 1331, and the pressing area 1331 is an arc surface that is concave toward the detection member 31 relative to the outer surface 1313 of the light-transmitting portion 131. In this way, when the user presses the button portion 133, a unique touch feeling can be given to the user, and a positioning prompt can be given to the user, which can effectively improve the accuracy of the user when operating the button portion 133 without looking at the button portion 133. Furthermore, based on the setting of the concave arc surface, if the outer surface 1313 of the light-transmitting portion 131 is a convex arc surface that is set in a direction away from the light-emitting member 33 relative to the outer surface 1333 of the button portion 133, the pressing area 1331 can form a contrast with the outer surface 1313 of the light-transmitting portion 131, and the concave arc surface can adapt to the surface of the finger, so that the pressing area 1331 and the light-transmitting portion 131 can be distinguished by the difference in touch feeling, and the probability of the user pressing the light-transmitting portion 131 when it is difficult to find the pressing area 1331 during blind operation is reduced. In addition, based on the external aesthetics, the pressing area 1331 is a setting form of an arc surface that is concave relative to the outer surface 1313 of the light-transmitting portion 131 toward the detection member 31, so that the button portion 133 is not abrupt in appearance compared to the main shell 11, so as to improve the overall aesthetics of the handle tube 10. In other embodiments, the pressing area 1331 may also be an arc surface that is raised relative to the outer surface 1313 of the light-transmitting portion 131 in a direction away from the detection member 31 , or may also be a plane, which is not limited in the present application.
[0079] Please continue reading Figure 6 as well as Fig.11In some embodiments, in the radial direction of the handle tube 10 and in the direction toward the inside of the handle tube 10, the inner surface 1335 of the button portion 133 is higher than the inner surface 1315 of the light-transmitting portion 131. In addition, the inner surface 1335 of the button portion 133 may be a plane facing the detection member 31 or an arcuate surface convexly disposed toward the detection member 31. It is understandable that the embodiment of the present application shortens the distance between the inner surface 1335 of the button portion 133 and the detection member 31, so that the pressing stroke between the button portion 133 and the detection member 31 is shortened, so that the operating force required by the user when pressing the button portion 133 is also reduced accordingly, which can not only improve the sensitivity of triggering the detection member 31 when pressing, but also the user can complete the operation of pressing the button portion 133 to press or abut the detection member 31 more quickly, which can effectively improve the user's experience. In other embodiments, in the radial direction of the handle tube 10 and toward the interior of the handle tube 10, the inner surface 1335 of the button portion 133 may also be lower than the inner surface 1315 of the light-transmitting portion 131, or in the radial direction of the handle tube 10 and toward the interior of the handle tube 10, the inner surface 1335 of the button portion 133 and the inner surface 1315 of the light-transmitting portion 131 are at the same height, and the embodiments of the present application are not limited to this.
[0080] See also Figure 6 as well as Fig.11 In some embodiments, the inner surface 1315 of the light-transmitting portion 131 includes an inner light-transmitting area 1311 (eg, Fig.10 ), the inner light-transmitting area 1311 is an arc surface that is concave relative to the inner surface 1335 of the button portion 133 in a direction away from the light-emitting element 33. In this way, the overall thickness of the light-transmitting portion 131 can be reduced, and the refraction and deformation of the light emitted by the light-emitting element 33 when passing through the light-transmitting portion 131 can be reduced, thereby improving the final display effect of the light.
[0081] On the basis of this embodiment, further, the outer surface 1313 of the light-transmitting portion 131 is a curved surface that is convex relative to the outer surface 1333 of the button portion 133 in the direction away from the light-emitting member 33. In this way, the outer surface 1313 and the inner surface of the light-transmitting portion 131 are both curved surfaces that are convex outward, which can make the thickness of each position of the light-transmitting portion 131 relatively uniform, and at the same time, it has a certain structural strength, and can avoid a large degree of refraction of light in the light-transmitting portion 131, thereby improving the final display effect of the light. In other embodiments, the inner light-transmitting area 1311 can also be a plane or a curved surface that is convex relative to the inner surface 1335 of the button portion 133 in the direction toward the light-emitting member 33, and the present application does not limit this.
[0082] See also Fig.12In some embodiments, the interactive shell 13 further includes a light shielding layer 135, which covers the surface of the interactive shell 13 and avoids the light-transmitting portion 131. In this way, the light-emitting range of the light emitted by the light-emitting element 33 is limited by the light-shielding layer 135, and the light-transmitting portion 131 is correspondingly arranged with the light-emitting element 33, so that the light emitted by the light-emitting element 33 can be transmitted to the outside of the handle tube 10 through the light-transmitting portion 131.
[0083] Specifically, the light shielding layer 135 can be light shielding paint, light shielding ink or light shielding cloth, etc., which is not limited in this embodiment. For example, the light shielding layer 135 can be set on the inner surface of the interactive shell 13 and avoid the inner light-transmitting area 1311. Compared with the light shielding layer 135 being set on the outer surface of the interactive shell 13, it can prevent the light shielding layer 135 from falling off due to friction.
[0084] In the actual manufacturing process, the workshop can first form the interactive shell 13 including the light-transmitting portion 131 and the button portion 133 in one-time molding, and then, on the basis of the interactive shell 13 prepared as an integrally molded component, the shading layer 135 is arranged on the inner surface or outer surface of the interactive shell 13 and avoids the inner light-transmitting area 1311. At the same time, on the basis that the inner surface 1315 of the light-transmitting portion 131 includes the inner light-transmitting area 1311, and the inner light-transmitting area 1311 is an arc surface that is recessed relative to the inner surface 1335 of the button portion 133 in the direction away from the light-emitting component 33, the inner light-transmitting area 1311 can play a avoiding role to prevent the shading layer 135 from being applied to the light-transmitting portion 131.
[0085] See also Figure 10-11 In some embodiments, the pressing area 1331 is an arc surface that is recessed toward the detection member 31 relative to the outer surface 1313 of the light-transmitting portion 131. The outer surface 1313 of the light-transmitting portion 131 is an arc surface that is convex relative to the pressing area 1331 in the direction away from the light-emitting member 33, and the outer surface 1313 of the light-transmitting portion 131 and the pressing area 1331 are smoothly transitioned. In this way, when the user presses the button portion 133, the user can be given a unique touch feeling, and the user can be given a positioning prompt while making the light-transmitting portion 131 a larger viewing angle for the user to observe. On this basis, by setting the outer surface 1313 of the light-transmitting portion 131 and the pressing area 1331 to have a smooth transition, not only can the interactive shell 13 be prevented from being uncomfortable to the hand, but also the user's line of sight of the light-transmitting portion 131 of the interactive shell 13 can be prevented from being blocked when there is a step structure between the button area and the outer surface 1313 of the light-transmitting portion 131.
[0086] See also Figure 13-Figure 15In some embodiments, the main shell 11 includes a metal shell 111 and a plastic lining 113. The metal shell 111 has the above-mentioned installation opening 1111. The interactive shell 13 is installed in the installation opening 1111 to cover the installation opening 1111. The plastic lining 113 is arranged on the inner wall of the metal shell 111. The movement 30 is connected to the plastic lining 113. The plastic lining has a through hole 1131 connected to the installation opening 1111. The button part 133 cooperates with the detection part 31 through the through hole 1131. The light emitted by the light-emitting part 33 passes through the through hole 1131 and the light-transmitting part 131 in turn.
[0087] It is understandable that the metal shell 111 may be aluminum or stainless steel, etc., and the plastic liner 113 may be a plastic part. The plastic liner 113 may be connected to the inner wall of the metal shell 111 by an injection molding process or a dispensing assembly process. The plastic liner 113 may be provided with a connection structure to cooperate with the bracket 34 of the movement 30 through the connection structure. For example, the connection structure may include a snap-on structure, a limit structure, a guide structure, and a fixing structure. Since the plastic liner 113 is a plastic part, the connection structure can be easily formed by an injection molding process, and connected to the bracket 34 of the movement 30 through the connection structure, so as to achieve fixed installation of the bracket 34 of the movement 30 in the handle tube 10.
[0088] Relatively speaking, if a connection structure is provided on the inner wall of the metal shell 111, it will be very difficult to process. Common metal processing processes include forging, die casting, compression casting, etc. Since the forging process is centered on forging, it is impossible to form a connection structure. Although the die casting process and the compression casting process can form a connection structure, they cannot accurately form a connection structure at a specific position on the inner wall of the metal shell 111, resulting in the connection structure being unable to align with the movement 30.
[0089] Please continue reading Figure 13-Figure 15 The diameter of the through hole 1131 is smaller than the installation opening 1111, so that a ring-shaped bearing platform 115 is formed at the bottom of the installation opening 1111, and the bearing platform 115 supports the interactive shell 13. That is, a step structure is formed between the plastic liner 113 and the metal shell 111, and the step surface of the step structure forms the bearing platform 115. The interactive shell 13 is supported by the bearing platform 115, so that the interactive shell 13 will not be sunken into the handle tube 10, especially when the interactive shell 13 includes a button part 133, the button part 133 is pressed by the user, which is easy to cause the button part to sink. The bearing platform 115 can solve this problem.
[0090] It should be noted that when the interactive shell 13 is a hard, light-transmitting plastic part, since the interactive shell 13 has better inherent strength, the interior of the handle tube 10 may selectively not be provided with a supporting structure for supporting the interactive shell 13, for example, the supporting platform 115 may selectively not be provided, thereby simplifying the overall structure of the handle tube 10.
[0091] See also Figure 13-Figure 15 In some embodiments, the surface of the carrier 115 supporting the interactive shell 13 has an annular glue-filling groove 1151, and glue (not shown in the figure) is arranged in the glue-filling groove 1151, and the glue is bonded to the edge area of the inner surface of the interactive shell 13. It can be understood that the surface of the carrier 115 used to support the interactive shell 13 is an annular surface to support the interactive shell 13 in the annular direction, and the glue located in the glue-filling groove 1151 can be bonded to the inner surface of the interactive shell 13 in the annular direction of the carrier 115, so as to further improve the bearing stability of the carrier 115 on the interactive shell 13. For example, the button part 133 of the interactive shell 13 can be located in the middle area of the interactive shell 13 instead of the edge area. Based on this, not only can the bearing stability of the carrier 115 on the interactive shell 13 be improved, but also when the glue is bonded to the edge area of the inner surface of the interactive shell 13, it will not interfere too much with the deformation action of the button part 133 when it is pressed.
