Description

Technical Field

[0001] The present application relates to the technical field of oral cleaning, and in particular to an electric toothbrush and a handle shell thereof. Background Art

[0002] In the related art, some electric toothbrushes have a display function to guide the user's brushing operation or display information such as battery lighting.

[0003] In order to realize the display function, a light-transmitting display shell needs to be provided on the brush handle so that the light emitted by the internal display light source can pass through the brush handle. The display shell is usually bonded and fixed to the handle shell. When multiple display shells are provided on the brush handle to realize multi-screen display, multiple display shells need to be provided, which has high material cost and leads to low assembly efficiency.

From the user's point of view, the first light-transmitting portion and the second light-transmitting portion are continuous display areas, and therefore, the handle shell has a larger display area.

DETAILED DESCRIPTION

[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] See also Figure 1An embodiment of the present application provides an electric toothbrush 100 for cleaning a user's oral cavity. The electric toothbrush 100 includes a handle shell 10 , a brush head 20 , and a movement 30 disposed in the handle shell 10 .

[0055] The handle shell 10 is an appearance component of the electric toothbrush 100 and is suitable for being held by the user to facilitate the user to use the electric toothbrush 100. At the same time, the handle shell 10 can also protect the movement 30 installed therein.

[0056] The movement 30 is a power component for realizing the toothbrushing function of the electric toothbrush 100. The movement 30 may include a circuit board 31, a battery 32, and a motor 33. The battery 32 is used to supply power to the motor 33 and the circuit board 31. The circuit board 31 is used to control the operation of the motor 33. When the motor 33 is operating, the high-frequency vibration energy is transmitted to the brush head 20 through the output shaft. When the brush head 20 acts on the user's oral cavity, the cleaning function of the user's oral cavity can be realized.

[0057] In some embodiments, the electric toothbrush 100 also has a display function, which can provide prompts or guidance for the brushing process. Correspondingly, the movement 30 further includes a light-emitting element 34, which can include a lamp bead or a display screen. The light-emitting element 34 is electrically connected to the circuit board 31. Under the control of the circuit board 31, the light-emitting element 34 emits corresponding light when working, and the light is transmitted outside the handle shell 10 and seen by the user, thereby realizing the display function.

[0058] See also Figure 2 In order to make the handle shell 10 light-transmissive and realize the display function. In some embodiments, the handle shell 10 includes a shell 11, a button 12 and an integrated light-transmissive member 13.

[0059] The shell 11 may be cylindrical, and exemplarily, the shell 11 may be cylindrical, square cylindrical, or the shell 11 may be square cylindrical but the corners are rounded. The shell 11 is a non-light-transmitting member to prevent light from leaking through the shell 11 when the light-emitting member 34 emits light. The shell 11 has a first side 111 and a second side 112 that are adjacently arranged, and the first side 111 is connected to the second side 112; exemplarily, the first side 111 is the side where the button 12 is located, and the side where the bristle surface is located is the front side, and the second side 112 is the left side or the right side of the shell 11.

[0060] like Figure 2 As shown, the button 12 is located on the first side 111, and the button 12 can be on the same side as the bristle surface of the brush head 20. The button 12 is electrically connected to the circuit board 31, and the user can control the electric toothbrush 100 through the button 12, for example, turning on and off, adjusting the brushing mode, etc.

[0061] See also Figure 2-3The integrated light-transmitting member 13, as the name implies, can be understood as an integrated injection-molded component, and at least partially light-transmitting. The integrated light-transmitting member 13 is disposed on the outer surface of the housing 11, that is, the integrated light-transmitting member 13 is exposed to the housing 11, so that the integrated light-transmitting member 13 can be observed by the user, and the integrated light-transmitting member 13 is fixedly connected to the housing 11, so that the position of the integrated light-transmitting member 13 on the housing 11 is relatively fixed, which is convenient for the user to observe.

[0062] The integrated light-transmitting member 13 extends from the first side 111 to the second side 112 along the circumference of the housing 11. Specifically, the integrated light-transmitting member 13 forms a continuous first light-transmitting portion 131 and a second light-transmitting portion 132 on the outer surface of the housing 11. The first light-transmitting portion 131 is located on the first side 111, and the second light-transmitting portion 132 is located on the second side 112. That is, the integrated light-transmitting member 13 is formed with the first light-transmitting portion 131 on the first side 111 (that is, the side where the button 12 is located), and extends from the first side 111 to the second side 112, and forms the second light-transmitting portion 132 on the second side 112. The first light-transmitting portion 131 and the second light-transmitting portion 132 are continuous ( Figure 3 The dashed line dividing the first light-transmitting portion 131 and the second light-transmitting portion 132 is for illustration only). The first light-transmitting portion 131 and the second light-transmitting portion 132 can actually be used as a complete light-transmitting portion. Since the first light-transmitting portion 131 is located at the first side 111 and the second light-transmitting portion 132 is located at the second side 112, different names are used to distinguish the positions.

[0063] The aforementioned light-emitting component 34 is arranged corresponding to the first light-transmitting portion 131 and the second light-transmitting portion 132, that is, the light emitted by the light-emitting component 34 can pass through the first light-transmitting portion 131 and the second light-transmitting portion 132 to the outside of the handle shell 10, so that the user can observe the light emitted by the light-emitting component 34, that is, can observe the display content.

[0064] This embodiment has at least the following three technical effects by providing an integrated light-transmitting member 13:

[0065] First, lower material costs. In the related art, in order to achieve multi-screen display, it is usually necessary to set an independent display shell on each display area, that is, multiple display shells need to be set. In this embodiment, only one material, that is, an integrated light-transmitting member 13, is required. The integrated light-transmitting member 13 forms a first light-transmitting portion 131 and a second light-transmitting portion 132 on the first side 111 and the second side 112, respectively. The first light-transmitting portion 131 and the second light-transmitting portion 132 can realize the functions of two display shells, which can reduce material costs. And because the integrated light-transmitting member 13 is only one material, the production and assembly costs can be reduced.

[0066] Second, a larger display area. The first light-transmitting portion 131 and the second light-transmitting portion 132 are continuous, that is, the first light-transmitting portion 131 and the second light-transmitting portion 132 can actually be used as a complete light-transmitting portion. When the first light-transmitting portion 131 and the second light-transmitting portion 132 correspond to the same light-emitting component 34, for example, the light-emitting component 34 is a flexible display screen or a lamp bead matrix arranged toward the first light-transmitting portion 131 and the second light-transmitting portion 132, and the light emitted by the flexible display screen or the lamp bead matrix is ​​transmitted through the first light-transmitting portion 131 and the second light-transmitting portion 132 at the same time. From the user's point of view, the first light-transmitting portion 131 and the second light-transmitting portion 132 are continuous display areas, and therefore, the handle shell 10 has a larger display area.

[0067] Specifically in practical applications, when the user is brushing his teeth, the user's finger presses on the button 12. When brushing the teeth with the brush head 20 facing the outer tooth surface, the first side 111 faces the outer tooth surface, and the button 12 and the first light-transmitting portion 131 also face the outer tooth surface. The user's finger is almost parallel to the first side 111, and it is difficult for the user to observe the display content of the first light-transmitting portion 131. At this time, the user can obtain the display content by observing the second light-transmitting portion 132 of the first side 111.

[0068] Even if the first light-transmissive portion 131 and the second light-transmissive portion 132 correspond to different light-emitting components 34 respectively, for example, the first light-transmissive portion 131 and the second light-transmissive portion 132 correspond to two display screens or correspond to different lamp beads respectively, since there is no optical partition structure between the first light-transmissive portion 131 and the second light-transmissive portion 132, the first light-transmissive portion 131 and the second light-transmissive portion 132 have a larger light-transmissive area, and the light emitted by the light-emitting component 34 can be transmitted from the first light-transmissive portion 131 and the second light-transmissive portion 132 with a larger area, and the handle shell 10 also has a larger display area.

[0069] See also Figure 3 In some embodiments, the handle shell 10 also includes a lining 14, an integrated light-transmitting member 13 is arranged on the surface of the lining 14, and at least one of the lining 14 and the integrated light-transmitting member 13 is connected to the outer shell 11, thereby achieving a fixed connection between the lining 14 and the integrated light-transmitting member 13 and the outer shell 11. Exemplarily, the lining 14 and the integrated light-transmitting member 13 are both connected to the outer shell 11 to achieve a more stable connection between the three.

[0070] In some embodiments, the lining 14 is a non-light-transmitting member, for example, the lining 14 is a non-light-transmitting plastic. The lining 14 has a first hollow hole 14a corresponding to the first light-transmitting portion 131 and a second hollow hole 14b corresponding to the second light-transmitting portion 132. The light emitted by the light-emitting member 34 can sequentially pass through the first hollow hole 14a and the first light-transmitting portion 131 to the outside of the handle shell 10, and sequentially pass through the second hollow hole 14b and the second light-transmitting portion 132 to the outside of the handle shell 10, thereby realizing the large-area display function of the electric toothbrush 100.

[0071] Furthermore, the first hollow hole 14a and the second hollow hole 14b are filled with the integrated light-transmitting member 13, that is, the integrated light-transmitting member 13 extends into the first hollow hole 14a and the second hollow hole 14b. In this way, on the basis of realizing the large-area display function of the electric toothbrush 100, the contact area between the integrated light-transmitting member 13 and the lining 14 is increased, the connection stability between the integrated light-transmitting member 13 and the lining 14 is improved, and the integrated light-transmitting member is prevented from falling off the lining 14.

[0072] In other embodiments, the lining 14 is a light-transmitting member, such as a light-transmitting plastic. The handle shell 10 further includes a light-shielding layer (not shown in the figure), which is disposed between the lining 14 and the integrated light-transmitting member 13, that is, the light-shielding layer is disposed on the inner surface of the integrated light-transmitting member 13. Compared with disposing the blocking layer on the outer surface of the integrated light-transmitting member 13, the light-shielding layer can be prevented from being rubbed off by external objects. And the shading layer avoids the first light-transmitting portion 131 and the second light-transmitting portion 132, that is, the surface area of ​​the integrated light-transmitting component 13 that is not blocked by the shading layer is arranged corresponding to the first light-transmitting portion 131 and the second light-transmitting portion 132, so that the light emitted by the light-emitting component 34 can be transmitted through the first light-transmitting portion 131 and the second light-transmitting portion 132 to the outside of the handle shell 10, while the area of ​​the integrated light-transmitting component 13 blocked by the shading layer is not light-transmitting, avoiding light leakage, so that the light emitted by the light-emitting component 34 is concentrated to be transmitted through the first light-transmitting portion 131 and the second light-transmitting portion 132, thereby achieving high-contrast and high-brightness display.

[0073] In some embodiments, the lining 14 is a light-transmitting member, such as a light-transmitting plastic. The handle shell 10 also includes a coating layer (not shown in the figure) and a light-shielding layer (not shown in the figure). The coating layer is disposed on the outer surface of the integrated light-transmitting member 13. The light-shielding layer is disposed between the coating layer and the integrated light-transmitting member 13. The coating layer can not only improve the smoothness of the surface of the integrated light-transmitting member 13, but also protect the light-shielding layer to prevent the light-shielding layer from being worn by external objects. Exemplarily, the coating layer can be an anti-reflection film layer, which can transmit more light, so that the first light-transmitting portion 131 and the second light-transmitting portion 132 have a clearer display effect.

[0074] The light-shielding layer is disposed between the coating layer and the integrated light-transmitting member 13, and further, the light-shielding layer avoids the first light-transmitting portion 131 and the second light-transmitting portion 132. That is, the surface area of ​​the integrated light-transmitting member 13 that is not blocked by the light-shielding layer is disposed corresponding to the first light-transmitting portion 131 and the second light-transmitting portion 132, so that the light emitted by the light-emitting member 34 can be transmitted from the first light-transmitting portion 131 and the second light-transmitting portion 132 to the outside of the handle shell 10, while the area of ​​the integrated light-transmitting member 13 blocked by the light-shielding layer is not light-transmitting, thereby avoiding light leakage, so that the light emitted by the light-emitting member 34 is concentratedly transmitted from the first light-transmitting portion 131 and the second light-transmitting portion 132, thereby achieving high-contrast and high-brightness display.

[0075] In some embodiments, the lining 14 is formed on the inner wall of the outer shell 11 through an injection molding process. In this way, the connection tightness between the lining 14 and the outer shell 11 can be strengthened, the lining 14 is not easy to separate from the inner wall of the outer shell 11, and the assembly process can be simplified. After the outer shell 11 is formed, the lining 14 can be formed on the inner wall of the outer shell 11 through an injection molding process.

[0076] In some embodiments, the integrated light-transmitting member 13 is formed on the surface of the lining 14 by injection molding. That is, the lining 14 is first formed, and the integrated light-transmitting member 13 is formed on the surface of the lining 14 by injection molding. In this way, the connection tightness between the lining 14 and the integrated light-transmitting member 13 can be strengthened, the integrated light-transmitting member 13 is not easy to be separated from the lining 14, and the assembly process can be simplified.

[0077] In this embodiment, the reason why the lining 14 is molded first and then the integrated light transmissive component 13 is molded is that the lining 14 can be a non-light transmissive component and needs to be injection molded with a non-light transmissive material; while the integrated light transmissive component 13 needs to be injection molded with a light transmissive material. The injection molding materials of the lining 14 and the integrated light transmissive component 13 are different. Therefore, the lining 14 and the integrated light transmissive component 13 need to be injection molded separately.

[0078] In other embodiments, the lining 14 and the integrated light-transmitting member 13 are both light-transmitting members. After the outer shell 11 is formed, the lining 14 and the integrated light-transmitting member 13 can be simultaneously formed in a one-time injection molding process. In this way, the injection molding process is simpler, and the connection stability between the outer shell 11, the lining 14 and the integrated light-transmitting member 13 is better.

[0079] Please continue reading Figure 2-3In some embodiments, the outer shell 11 is a metal part, and the metal part is sleeved on the inner lining 14. By setting the outer shell 11 as a metal part, such as aluminum, stainless steel, etc., and taking advantage of the high hardness of the metal part, the handle shell 10 can have a higher structural strength. Relatively speaking, the inner lining 14 and the integrated light-transmitting part 13 can be made of a material with a relatively soft hardness, which facilitates the injection molding of the inner lining 14 and the integrated light-transmitting part 13 and can improve the touch feel of the integrated light-transmitting part 13. The metal part is sleeved on the inner lining 14 to protect the inner lining 14.

[0080] See also Figure 4-6 In some embodiments, the total thickness H1 of the integrated light transmissive member 13 and the inner lining 14 is not less than 1.2 mm and not more than 4 mm. In this way, the integrated light transmissive member 13 has a moderate thickness, has a high structural strength, and has a better observation angle. If the total thickness H1 of the integrated light transmissive member 13 and the inner lining 14 is less than 1.2 mm, the overall thickness of the integrated light transmissive member 13 is too thin, the structural strength is insufficient, and structural damage is prone to occur. If the total thickness H1 of the integrated light transmissive member 13 and the inner lining 14 is greater than 4 mm, the overall thickness of the integrated light transmissive member 13 is too thick, the distance from the outer surface of the integrated light transmissive member 13 to the light emitting member 34 is large, and it is not easy for the user to observe the display content of the light emitting member 34.

[0081] In some embodiments, the thickness of each of the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132 is not less than 0.3 mm. In this way, the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132 are convenient to be molded by the injection molding process, and the surfaces of the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132 are ensured to be relatively smooth. If the thickness of the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132 is less than 0.3 mm, the thickness is too thin, resulting in increased difficulty in injection molding, and potholes will appear on the surface of the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132, and the structural strength of the lining 14, the first light-transmitting portion 131, and the second light-transmitting portion 132 is not enough, and deformation or structural damage is prone to occur.

[0082] In some embodiments, the thickness H2 of the integrated light-transmitting member 13 is greater than the thickness H3 of the lining 14. Since the integrated light-transmitting member 13 is disposed on the surface of the lining 14, by setting the thickness H2 of the integrated light-transmitting member 13 to be greater than the thickness H3 of the lining 14, the structural strength of the integrated light-transmitting member 13 can be improved, and the risk of the integrated light-transmitting member 13 being damaged by external forces can be reduced.

[0083] In some embodiments, the integrated light-transmitting member 13 is a light-transmitting hard plastic member. Since the integrated light-transmitting member 13 is disposed on the surface of the inner lining 14, by configuring the integrated light-transmitting member 13 as a light-transmitting hard plastic member, the structural strength of the integrated light-transmitting member 13 can be improved, and the risk of damage to the integrated light-transmitting member 13 by external forces can be reduced. In addition, the light-transmitting hard plastic member can protect the internal light-emitting member 34. If the integrated light-transmitting member 13 is configured as a light-transmitting soft plastic member, since the integrated light-transmitting member 13 is easily deformed, the deformation of the integrated light-transmitting member 13 is likely to squeeze the light-emitting member 34, causing the light-emitting member 34 to shift, structural damage, or circuit breakage.

[0084] See also Figure 2 In some embodiments, the button 12 is integrally formed on the integral light-transmitting member 13. This not only simplifies the molding process of the button 12, but also the button 12 and the first light-transmitting portion 131 are seamlessly connected, which can improve the sealing performance of the button 12 and prevent liquid from entering the handle shell 10 through the gap around the button 12 during brushing.

[0085] Please continue reading Figure 2 In some embodiments, the handle shell 10 includes a top end 10a close to the brush head 20 of the electric toothbrush 100 and a bottom end 10b away from the brush head 20. The integrated light-transmitting member 13 is closer to the top end 10a than the bottom end 10b. In this way, the integrated light-transmitting member 13 is located in the upper half of the handle shell 10 close to the brush head 20, and the lower half of the handle shell 10 away from the brush head 20 is for the user to hold. The user will not hold the integrated light-transmitting member 13, which is convenient for the user to observe the integrated light-transmitting member 13. The first light-transmitting portion 131 and the second light-transmitting portion 132 are located between the button 12 and the top end 10a. In this way, when the user operates the button 12, the first light-transmitting portion 131 and the second light-transmitting portion 132 will not be blocked by the user's hand, which is more convenient for the user to observe the integrated light-transmitting member 13.

[0086] See also Figure 2-4 In some embodiments, the housing 11 includes a gripping section 115 and a connecting section 116 connected to opposite ends of the integrated light-transmitting member 13, the gripping section 115 is used for the user to hold, and the connecting section 116 is used to connect with the brush head 20. The connecting section 116 is arranged near the brush head 20 of the electric toothbrush 100. Along the axial direction of the handle housing 10, the connecting section 116 has a first length L1, the integrated light-transmitting member 13 has a second length L2, and the gripping section 115 has a third length L3.

[0087] In some embodiments, the ratio of the first length L1 to the second length L2 is not less than 1 / 4 and not greater than 1 / 2, and the ratio of the second length L2 to the third length L3 is not less than 1 / 2 and not greater than 3; in this way, the length distribution of the connecting section 116, the integrated light-transmitting member 13 and the holding section 115 is appropriate, so that the connecting section 116 and the integrated light-transmitting member 13 are located in the upper half of the handle shell 10, which is convenient for the connection between the connecting section 116 and the brush head 20, and convenient for the user to observe the integrated light-transmitting member 13, and the holding section 115 is located in the lower half of the handle shell 10, with sufficient length for the user to achieve stable grip.

[0088] If the ratio of the first length L1 to the second length L2 is less than 1 / 4, the length of the connecting section 116 is too short, the structural strength of the connecting section 116 is reduced, and the connection stability with the brush head 20 is reduced. In addition, the length of the integrated light-transmitting member 13 is too long. In fact, the first light-transmitting portion 131 and the second light-transmitting portion 132 do not need to be too long, resulting in a waste of space in the length direction of the handle shell 10. If the ratio of the first length L1 to the second length L2 is greater than 1 / 4, the length of the connecting section 116 is too long, and the length of the integrated light-transmitting member 13 is too short, resulting in the first light-transmitting portion 131 and the second light-transmitting portion 132 being too short, which is not conducive to setting a large area of ​​the first light-transmitting portion 131 and the second light-transmitting portion 132. In addition, the connecting section 116 squeezes the integrated light-transmitting member 13 toward the gripping section 115, so that the integrated light-transmitting member 13 may be held by the user, resulting in the integrated light-transmitting member 13 being blocked, which is not convenient for the user to observe.

[0089] If the ratio of the second length L2 to the third length L3 is less than 1 / 2, the length of the integrated light-transmitting member 13 is too short, resulting in the first light-transmitting portion 131 and the second light-transmitting portion 132 being too short, which is not conducive to setting a large area of ​​the first light-transmitting portion 131 and the second light-transmitting portion 132. If the ratio of the second length L2 to the third length L3 is greater than 3, the length of the integrated light-transmitting member 13 is too long, resulting in the length of the gripping section 115 being too short, and the integrated light-transmitting member 13 squeezes the gripping section 115, so that the integrated light-transmitting member 13 may be held by the user, resulting in the integrated light-transmitting member 13 being blocked, which is not convenient for the user to observe.

[0090] In some embodiments, the first length L1 is not less than 10 mm, so that the connecting section 116 is long enough and has sufficient structural strength to support the integrated light-transmitting member 13. The second length L2 is not less than 30 mm, so that the integrated light-transmitting member 13 is long enough to set the first light-transmitting portion 131 and the second light-transmitting portion 132 of sufficiently large area. The third length L3 is not less than 40 mm, so that the gripping section 1115 is long enough to facilitate the user to hold and avoid the user holding the integrated light-transmitting member 13. And the total length of the handle shell 10 is not less than 100 mm, so that the length distribution of the connecting section 116, the integrated light-transmitting member 13 and the gripping section 115 is appropriate, so that the connecting section 116 and the integrated light-transmitting member 13 are located in the upper half of the handle shell 10, which is convenient for the connecting section 116 to connect with the brush head 20, and convenient for the user to observe the integrated light-transmitting member 13, and the gripping section 115 is located in the lower half of the handle shell 10, with sufficient length for the user to achieve stable grip.

[0091] See also Figure 2 In some embodiments, the connecting section 116 includes a tapered portion 1161. Along the direction close to the brush head 20, the radial cross-section of the tapered portion 1161 is tapered, and the integrated light-transmitting member 13 does not extend to the tapered portion 1161, that is, the integrated light-transmitting member 13 is located between the tapered portion 1161 and the gripping section 115. In this way, the integrated light-transmitting member 13 does not follow the tapered portion 1161, thereby avoiding the refraction of the light emitted by the light-emitting member 34 when the integrated light-transmitting member 13 is tapered, thereby causing distortion of the displayed content.

[0092] Please continue reading Figure 4 In other embodiments, along the direction close to the brush head 20, the radial cross section of the connecting section 116 remains unchanged, the connecting section 116 has a top 10a close to the brush head 20, and along the length direction of the handle shell 10, the minimum distance between the integrated light-transmitting member 13 and the top 10a (i.e. Figure 4 The first length L1 shown in FIG is not less than 5 mm. In this way, the connecting section 116 between the integrated light-transmitting member 13 and the top end 10a can have a certain length and sufficient structural strength to support the integrated light-transmitting member 13. In addition, it can also prevent the liquid from flowing directly onto the integrated light-transmitting member 13 during brushing, thereby blocking the displayed content.

[0093] If the minimum distance between the integrated light-transmitting member 13 and the top 10a is not less than 5 mm, the length of the connecting section 116 between the integrated light-transmitting member 13 and the top 10a is too short, and there is insufficient structural strength to support the integrated light-transmitting member 13, which may easily lead to structural damage of the connecting section 116 and the integrated light-transmitting member 13. In addition, the liquid in the process of brushing teeth may easily flow directly onto the integrated light-transmitting member 13, thereby blocking the displayed content.

[0094] See also Figure 2-3 In some embodiments, the handle shell 10 is non-cylindrical, for example, the shell 11 is square cylindrical but the corners are rounded. The connection between the first light-transmitting portion 131 and the second light-transmitting portion 132 forms a light-transmitting rib 135, and the light-transmitting rib 135 is arranged corresponding to the corners of the shell 11. The first light-transmitting portion 131 is continuously arranged with the second light-transmitting portion 132 through the light-transmitting rib 135. In this way, even if the first light-transmitting portion 131 and the second light-transmitting portion 132 face different directions, they can be continuously connected through the light-transmitting rib 135, so that the first light-transmitting portion 131, the light-transmitting rib 135 and the second light-transmitting portion 132 constitute a light-transmitting portion as a whole, thereby increasing the display area.

[0095] Please continue reading Figure 2-3 as well as Figure 7 In some embodiments, the housing 11 further includes a third side 113, the third side 113 is disposed adjacent to the second side 112 and opposite to the first side 111, the integrated light-transmitting member 13 further extends to the third side 113, so as to form a third light-transmitting portion 133 continuous with the second light-transmitting portion 132 on the outer surface of the housing 11, and the third light-transmitting portion 133 is located on the third side 113. Exemplarily, the first side 111 is the front side, the second side 112 is the left side, and the third side 113 is the back side. The integrated light-transmitting member 13 extends from the first side 111 to the third side 113 via the second side 112, so that the first light-transmitting portion 131, the second light-transmitting portion 132 and the third light-transmitting portion 133 constitute a complete light-transmitting portion, further increasing the display area.

[0096] In some embodiments, the housing 11 further includes a fourth side 114, which is disposed adjacent to the first side 111 and opposite to the second side 112, and the integrated light-transmitting member 13 further extends to the fourth side 114, so as to form a fourth light-transmitting portion 134 continuous with the first light-transmitting portion 131 on the outer surface of the housing 11, and the fourth light-transmitting portion 134 is located on the fourth side 114. Exemplarily, the first side 111 is the front side, the second side 112 is the left side, and the fourth side 114 is the right side. The integrated light-transmitting member 13 extends from the fourth side 114 to the second side 112 via the first side 111, so that the fourth light-transmitting portion 134, the first light-transmitting portion 131, and the second light-transmitting portion 132 constitute a complete light-transmitting portion, further increasing the display area.

[0097] Furthermore, the integrated light-transmitting member 13 is arranged around the outer shell 11, that is, the integrated light-transmitting member 13 extends from the first side 111 to the second side 112 and the third side 113 to the fourth side 114, and the integrated light-transmitting member 13 is arranged in a ring shape to constitute an annular light-transmitting portion on the outer shell 11, so that the handle shell 10 has a light-transmitting position at any position in the circumferential direction, and an annular flexible display screen or a ring-arranged lamp bead matrix is ​​provided inside the handle shell 10, so that an annular display of the handle shell 10 can be achieved, so that when the user observes the handle shell 10 from any radial direction of the handle shell 10, part of the display content can be observed, so that the electric toothbrush 100 has a more comprehensive display function.
