Description

Technical Field

[0001] This utility model relates to the field of oral hygiene tools, and in particular to an electric toothbrush. Background Technology

[0002] Electric toothbrushes use a motor to generate high-frequency vibrations in the brush head, instantly breaking down toothpaste into fine foam that deeply cleans between teeth. Simultaneously, the bristle vibrations promote blood circulation in the mouth and massage the gum tissue. Therefore, people tend to prefer using electric toothbrushes for oral hygiene.

[0003] In related technologies, a display area is set on one side of the handle, and the mechanism inside the handle has a display screen directly opposite and spaced from the display area, so that the user can view the display screen through the display area. However, because the handle is cylindrical, this results in a large distance between the display area and the display screen, and a large depth of field. When the user views the display screen, their line of sight is not completely perpendicular to the display screen, making it difficult to see the content displayed on the screen, and their line of sight is easily blocked by the opaque parts of the handle. Utility Model Content

[0004] This utility model embodiment discloses an electric toothbrush with a display screen attached to the light-transmitting part, resulting in a small depth of field, making it easy for users to see the content displayed on the screen, and the line of sight is not easily obstructed by the handle shell.

[0005] In a first aspect, this utility model discloses an electric toothbrush, including a handle shell, a display shell, a display screen, and a motor. The display shell has a mounting portion and a light-transmitting portion. The mounting portion is located on the periphery of the handle shell, and the light-transmitting portion is located on the mounting portion and is disposed away from the handle shell relative to the mounting portion. The display screen is located on the mounting portion, and the display surface of the display screen is attached to the light-transmitting portion. The motor is located inside the handle shell, and the motor is electrically connected to the display screen.

[0006] In this embodiment, the mounting portion of the display housing is located on the periphery of the handle housing, and the light-transmitting portion is located on the mounting portion, with the light-transmitting portion positioned away from the handle housing relative to the mounting portion. This allows the display screen to be mounted on the light-transmitting portion, ensuring the display surface is flush with the light-transmitting portion, resulting in a shallow depth of field. This facilitates the user's viewing of the displayed content, and the view is less likely to be obstructed by the handle housing. Furthermore, a mechanism is housed within the handle housing, which is electrically connected to the display screen to drive its operation.

[0007] As an optional implementation, in this embodiment of the present invention, the handle housing is provided with a display window, and the mounting part of the display housing is disposed on the display window.

[0008] In this way, by setting a display window on the handle housing, the display window can provide installation space for the display housing, and the mounting part of the display housing is set on the display window, and the display screen is mounted using the mounting part.

[0009] As an optional implementation, in this embodiment of the present invention, the display window is a through hole, the display window is connected to the handle shell and the mounting part, the mechanism includes a main board, the main board is provided with a power receiving part, the main board is disposed inside the handle shell, and the power receiving part is arranged corresponding to the position of the display window, and the power receiving part is electrically connected to the display screen.

[0010] In this way, a wiring channel is formed by connecting the handle housing and the mounting part through the display window. This allows the power connector on the motherboard and the display screen to be electrically connected via this channel. Furthermore, by positioning the power connector relative to the display window, the power connector is placed as close to the display screen as possible, thereby shortening the wiring channel and reducing the difficulty of electrical connection.

[0011] As an optional implementation, in this embodiment of the present invention, the electric toothbrush further includes an electrical connector, one end of which is electrically connected to the display screen, and the other end of which extends through the display window into the handle housing and is electrically connected to the power receiving part.

[0012] In this way, one end of the electrical connector is connected to the display screen, and the electrical connector can extend into the handle housing through the wiring channel formed by the display window, so that the other end of the electrical connector is electrically connected to the power receiving part, realizing the electrical connection between the display screen and the motherboard. The wiring is relatively simple and reliable.

[0013] As an optional implementation, in this embodiment of the present invention, the wiring distance from the electrical connection point between the display screen and the electrical connector to the power receiving part is d1, and the length of the electrical connector is L, where L > d1.

[0014] In this way, since the length L of the electrical connector is greater than the wiring distance d1, the electrical connector has a certain length redundancy when its two ends are electrically connected to the display screen and the power receiving part, respectively. The value of this length redundancy is L-d1. This reduces the difficulty of assembly, that is, the difficulty of electrically connecting the two ends of the electrical connector to the display screen and the power receiving part by welding, screwing or other methods. At the same time, it can avoid the situation where the relative position of the display screen and the power receiving part changes unexpectedly and pulls on the electrical connector, causing the power connection at both ends of the electrical connector to fail.

[0015] As an optional implementation, in this embodiment of the present invention, the electrical connector includes a first end, a second end, and a free segment located between the first end and the second end. The first end is electrically connected to the display screen, and the second end is electrically connected to the power receiving part. The free segment is used to allow the electrical connector to be in a relaxed state when the first end and the second end are electrically connected to the display screen and the power receiving part, respectively.

[0016] In this way, when the first end and the second end of the electrical connector are electrically connected to the display screen and the power receiving part respectively, the electrical connector can realize the electrical connection between the display screen and the power receiving part. At the same time, the free section located between the first end and the second end is in a relaxed state, which can provide assembly margin for assembling the electric toothbrush and facilitate assembly.

[0017] As an optional implementation, in this embodiment of the present invention, L-d1≥10mm.

[0018] Thus, the length redundancy formed by the difference between the length L of the electrical connector and the wiring distance d1 results in a length redundancy greater than or equal to 10mm. This significant length redundancy effectively reduces assembly difficulty and prevents the electrical connector from being pulled or stretched. Furthermore, L-d1 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and this embodiment does not impose a specific limitation on it.

[0019] As an optional implementation, in this embodiment of the present invention, the thickness of the light-transmitting part is t along the orientation direction of the display surface of the display screen, where 0.4mm≤t≤3.5mm.

[0020] In this way, the structure of the light-transmitting part has high strength, which can provide effective protection for the display screen. In addition, the distance from the side of the light-transmitting part away from the display screen is small, resulting in a shallow depth of field, which makes it easier to view the content displayed on the display screen.

[0021] As an optional implementation, in this embodiment of the invention, the display shell gradually bulges along the direction close to the handle shell to form an arc shape;

[0022] Alternatively, the display housing has a plane facing the handle housing and a peripheral side surface connected to the plane, the peripheral side surface being configured as an arcuate surface that gradually bulges in the direction close to the handle housing.

[0023] In this way, by gradually bulging outwards from the handle housing to form an arc shape, the display shell prevents water from flowing onto the display shell when the electric toothbrush is used, thus preventing water from adhering to the light-transmitting parts and affecting the user's viewing of the screen content.

[0024] As an optional implementation, in this embodiment of the present invention, the mounting part is provided with a support part, the display screen abuts against the support part, and the support part includes a support column and / or a support platform.

[0025] Thus, by providing a support unit in the mounting section, the display screen is supported by the support unit abutting against it, facilitating the installation of the display screen. Furthermore, various support unit structures are provided, allowing selection based on actual needs; this embodiment does not impose a specific limitation on any particular structure.

[0026] As an optional implementation, in this embodiment of the invention, a buffer is provided between the support portion and the display screen.

[0027] In this way, by setting a buffer between the support and the display screen, the display screen can be stably installed on the support during assembly, and the display screen can be prevented from shifting relative to the support when the electric toothbrush is subjected to external forces such as collisions or drops.

[0028] As an optional implementation, in this embodiment of the present invention, the display screen is provided with an electrical connector that is electrically connected to the mechanism, and the electrical connector is partially pressed between the support part and the buffer part.

[0029] In this way, by pressing the electrical connector between the bearing and the buffer, the electrical connector can be constrained, reducing its movement and preventing interference between it and other components. For example, it can prevent the electrical connector from rubbing against the display screen and causing damage to the display screen.

[0030] As an optional implementation, in this embodiment of the present invention, the mounting part is provided with a mounting groove, and the display screen is at least partially located in the mounting groove.

[0031] In this way, by accommodating at least part of the display screen through the mounting slot, installation space is provided, making the overall structure of the electric toothbrush more compact while protecting the display screen.

[0032] As an optional implementation, in this embodiment of the present invention, the display surface of the display screen is bonded to the light-transmitting part by a light-transmitting adhesive.

[0033] In this way, on the one hand, the display screen is bonded to the light-transmitting part with light-transmitting adhesive, which can improve the installation stability of the display screen; on the other hand, by utilizing the light-transmitting property of the light-transmitting adhesive, users can view the content displayed on the display screen through the light-transmitting part and the light-transmitting adhesive.

[0034] As an optional implementation, in this embodiment of the invention, the light-transmitting adhesive at least covers the display area of ​​the display surface.

[0035] In this way, the light-transmitting adhesive at least covers the display area of ​​the display surface, and the coverage area of ​​the light-transmitting adhesive is relatively large, resulting in better installation stability of the display screen.

[0036] As an optional implementation, in this embodiment of the present invention, the handle shell includes a main body and a support portion, the support portion is disposed on one side of the main body and protrudes from the main body, and the display shell is disposed on the support portion.

[0037] In this way, on the one hand, by providing a support part on one side of the main body, the display shell is mounted on the main body via the support part, thereby achieving the installation and fixation of the display shell and the handle shell. On the other hand, by utilizing the support part protruding from the main body and the display shell protruding from the handle shell, when using an electric toothbrush, water can be prevented from flowing from the handle shell to the display shell, thus preventing water from adhering to the light-transmitting part and affecting the user's viewing of the content displayed on the screen.

[0038] As an optional implementation, in this embodiment of the present invention, the support portion has a stepped portion at one end facing the display housing, and the stepped portion abuts against the display housing.

[0039] In this way, the stepped section provides support, allowing the display shell to be pre-positioned during assembly, reducing assembly difficulty.

[0040] As an optional implementation, in this embodiment of the present invention, a sealing element is provided between the display shell and the stepped portion.

[0041] In this way, waterproofing can be achieved by placing a seal between the display housing and the stepped portion.

[0042] As an optional implementation, in this embodiment of the present invention, the support portion has a first side and a second side connected together, the outer side of the display shell abuts against the first side, and the inner side of the display shell abuts against the second side.

[0043] In this way, by having the first side abut against the outer side of the display housing and the second side abut against the inner side of the display housing, the multiple sides abutting against each other can ensure that the support part is in close contact with the display housing, thus achieving a seal and waterproofing.

[0044] As an optional implementation, in this embodiment of the invention, the portion of the support that connects to the display housing is configured as an arc shape with a cross-section that gradually increases from the main body to the display housing.

[0045] In this way, by constructing the part connecting the support and the display shell into an arc shape, when the electric toothbrush is used, the arc shape gradually increases from the main body to the display shell. This arc shape can prevent water from flowing to the display shell, thereby preventing water from adhering to the light-transmitting part and affecting the user's viewing of the content displayed on the screen.

[0046] As an optional implementation, in this embodiment of the present invention, the outer side of the support portion is inclined to the outer surface of the main body portion, forming an included angle α, where 30°≤α<90°.

[0047] This effectively prevents water from flowing towards the support and then onto the display screen.

[0048] As an optional implementation, in this embodiment of the present invention, the distance between the projection of the outer edge of the support portion on the first surface and the projection of the connection between the support portion and the main body portion on the first surface is d2, where d2 ≥ 2 mm, and the first surface is the plane where the display surface of the display screen is located.

[0049] This design, with its larger spacing, minimizes the possibility of water flowing towards the support and subsequently towards the display screen.

[0050] As an optional implementation, in this embodiment of the present invention, the projection of the outer contour of the display screen onto the support portion is located within the outer contour of the support portion.

[0051] In this way, by placing the display screen within the outer contour of the support, the support can wrap around the display screen and form a stepped contact structure to support and protect the display screen.

[0052] As an optional implementation, in this embodiment of the present invention, the peripheral side of the display screen and the inner side of the support are spaced apart.

[0053] In this way, by setting the peripheral side of the display screen and the inner side of the support part at intervals, it is possible to avoid interference between the display screen and the support part, and to avoid the support part blocking the display screen.

[0054] As an optional implementation, in this embodiment of the present invention, the electric toothbrush further includes a light-shielding member, which is disposed on the side of the light-transmitting portion facing or away from the display screen, and the light-shielding member at least covers the non-display area of ​​the display screen.

[0055] In this way, by blocking the non-display area of ​​the screen with a light-blocking component, users can focus on viewing the display area of ​​the screen, allowing them to better see the content displayed on the screen and resulting in a better viewing experience.

[0056] As an optional implementation, in this embodiment of the present invention, the electric toothbrush further includes a brush head disposed in the handle housing, and the mechanism includes a servo motor disposed inside the handle housing, the servo motor being used to drive the brush head to vibrate electrically.

[0057] In this way, the servo motor drives the brush head to vibrate, and when the brush head acts on the user's mouth, it can clean the user's mouth and the cleaning effect is better.

[0058] As an optional implementation, in this embodiment of the invention, the servo motor is positioned opposite to and spaced apart from the display screen.

[0059] In this way, by separating the servo motor from the display screen, the vibration generated by the servo motor when driving the brush head to vibrate can be prevented from affecting the display screen.

[0060] As an optional implementation, in this embodiment of the present invention, the distance between the servo motor and the display screen is d, where d ≥ 3mm.

[0061] In this way, the distance d between the servo motor and the display screen is relatively large, which can minimize the impact of vibration generated by the servo motor on the display screen.

[0062] Compared with the prior art, the embodiments of this utility model have at least the following beneficial effects:

[0063] In this embodiment of the invention, the mounting portion of the display housing is located on the periphery of the handle housing, and the light-transmitting portion is located on the mounting portion, with the light-transmitting portion positioned away from the handle housing relative to the mounting portion. This design utilizes the light-transmitting portion to mount the display screen, ensuring the display surface is flush with the light-transmitting portion, resulting in a shallow depth of field. This facilitates the user's viewing of the displayed content and minimizes obstruction of the view by the handle housing. Furthermore, a mechanism is housed within the handle housing, which is electrically connected to the display screen to drive its operation. Attached Figure Description

[0073] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0075] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0076] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0077] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0078] This utility model discloses an electric toothbrush with a display screen that is attached to the light-transmitting part, resulting in a shallow depth of field. This makes it easy for users to see the content displayed on the screen, and the line of sight is not easily obstructed by the handle shell.

[0079] Please see Figures 1 to 3 This is a schematic diagram of the structure of an electric toothbrush 100 provided in an embodiment of the present utility model. The electric toothbrush 100 includes a handle shell 10, a display shell 20, a display screen 30, and a motor 40. The display shell 20 has a mounting part 21 and a light-transmitting part 22. The light-transmitting part 22 is disposed on the mounting part 21, which is located on the periphery of the handle shell 10. The light-transmitting part 22 is disposed away from the handle shell 10 relative to the mounting part 21. The display screen 30 is disposed on the mounting part 21, and the display surface 30a of the display screen 30 is attached to the light-transmitting part 22. The motor 40 is disposed inside the handle shell 10 and is electrically connected to the display screen 30.

[0080] In this embodiment, the mounting portion 21 of the display shell 20 is located on the periphery of the handle shell 10, and the light-transmitting portion 22 is located on the mounting portion 21, with the light-transmitting portion 22 positioned away from the handle shell 10 relative to the mounting portion 21. Thus, the display screen 30 is mounted using the light-transmitting portion 22, and the display surface 30a of the display screen 30 is in close contact with the light-transmitting portion 22, resulting in a shallow depth of field. This facilitates the user's viewing of the content displayed on the display screen 30, and the view is less likely to be obstructed by the handle shell 10. Furthermore, a mechanism 40 is provided inside the handle shell 10, which is electrically connected to the display screen 30 to drive its operation.

[0081] For example, such as Figure 2 and Figure 4 As shown, the handle housing 10 is provided with a display window 10a, and the display housing 20 is provided on the display window 10a. In this way, by providing the display window 10a on the handle housing 10, the display window 10a can provide installation space for the display housing 20, so that the mounting part 21 of the display housing 20 is provided on the display window 10a, and the display screen 30 is mounted by the mounting part 21.

[0082] In some embodiments, the display window 10a is a through hole, connecting the handle housing 10 and the mounting part 21. The mechanism 40 includes a main board 41, which has a power receiving part 41a. The main board 41 is located inside the handle housing 10, and the power receiving part 41a is positioned corresponding to the display window 10a. The power receiving part 41a is electrically connected to the display screen 30. Thus, the display window 10a connects the handle housing 10 and the mounting part 21, forming a wiring channel. This allows the power receiving part 41a of the main board 41 and the display screen 30 to be electrically connected through this wiring channel. Furthermore, by positioning the power receiving part 41a corresponding to the display window 10a, the power receiving part 41a is placed as close as possible to the display screen 30, thereby shortening the wiring channel and reducing the difficulty of electrical connection.

[0083] For example, such as Figure 4 and Figure 5 As shown, the electric toothbrush 100 also includes an electrical connector 50. One end of the electrical connector 50 is electrically connected to the display screen 30, and the other end of the electrical connector 50 extends through the display window 10a into the handle housing 10 and is electrically connected to the power receiving part 41a. In this way, by connecting one end of the electrical connector 50 to the display screen 30, the electrical connector 50 can extend into the handle housing 10 through the wiring channel formed by the display window 10a, thereby enabling the other end of the electrical connector 50 to be electrically connected to the power receiving part 41a, realizing the electrical connection between the display screen 30 and the main board 41. The wiring is relatively simple and reliable.

[0084] Optionally, the wiring distance from the electrical connection point between the display screen 30 and the electrical connector 50 to the power receiving part 41a is d1, and the length of the electrical connector 50 is L, where L > d1. Thus, because the length L of the electrical connector 50 is greater than the wiring distance d1, the electrical connector 50 has a certain length redundancy when its two ends are electrically connected to the display screen 30 and the power receiving part 41a respectively. This length redundancy is L - d1. This reduces the difficulty of assembly, specifically reducing the difficulty of electrically connecting the two ends of the electrical connector 50 to the display screen 30 and the power receiving part 41a respectively through welding, screwing, or other methods. Simultaneously, it avoids the situation where the relative positions of the display screen 30 and the power receiving part 41a unexpectedly change, causing the electrical connector 50 to be pulled and resulting in the power connection failure at both ends of the electrical connector 50.

[0085] The wiring distance d1 refers to the minimum wiring distance between the display screen 30 and the power receiving part 41a, which depends on the internal connection structure of the handle housing 10 and the display housing 20.

[0086] For example, the electrical connector 50 includes a first end 51, a second end 52, and a free segment 53 located between the first end 51 and the second end 52. The first end 51 is electrically connected to the display screen 30, and the second end 52 is electrically connected to the power receiving part 41a. The free segment 53 is used to keep the electrical connector 50 in a relaxed state when the first end 51 and the second end 52 are electrically connected to the display screen 30 and the power receiving part 41a, respectively. In this way, when the first end 51 and the second end 52 of the electrical connector 50 are electrically connected to the display screen 30 and the power receiving part 41a, respectively, the electrical connector 50 can realize the electrical connection between the display screen 30 and the power receiving part 41a. At the same time, the free segment 53 located between the first end 51 and the second end 52 is in a relaxed state, which can provide assembly margin for assembling the electric toothbrush 100, facilitating assembly. For example, when the first end 51 and the second end 52 of the electrical connector 50 are electrically connected to the display screen 30 and the power receiving part 41a respectively, and one of the display screen 30 and the motherboard 41 is positioned and installed, the assembly allowance provided by the free section 53 can prevent the electrical connector 50 from being pulled and causing a circuit break when the other is positioned and installed.

[0087] The relaxed state refers to the electrical connector 50 being in a non-tight state, which is the opposite of the following example: connecting points A and B with a wire of length 10mm, the distance between the two segments A and B is 10mm, or even slightly less than 10mm.

[0088] Optionally, L-d1 ≥ 10mm. This creates a length redundancy of 10mm or more through the difference between the length L of the electrical connector 50 and the wiring distance d1. This significant length redundancy effectively reduces assembly difficulty and prevents the electrical connector 50 from being pulled or stretched. Furthermore, L-d1 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc., and this embodiment does not impose a specific limitation on it.

[0089] For example, such as Figure 4 As shown, along the orientation direction of the display surface 30a of the display screen 30, the thickness of the light-transmitting part 22 is t, where 0.4mm ≤ t ≤ 3.5mm. If the thickness t of the light-transmitting part 22 is less than 0.4mm, the thickness of the light-transmitting part 22 is relatively small, resulting in low structural strength and insufficient protection for the display screen 30. If the thickness t of the light-transmitting part 22 is greater than 3.5mm, the thickness of the light-transmitting part 22 is relatively large, leading to a larger distance from the side of the light-transmitting part 22 away from the display screen 30 and a shallower depth of field, which affects the user's ability to view the content displayed on the display screen 30. Therefore, the thickness t of the light-transmitting part 22 can be 0.4mm ≤ t ≤ 3.5mm. This results in higher structural strength for the light-transmitting part 22, providing effective protection for the display screen 30, while also minimizing the distance from the side of the light-transmitting part 22 away from the display screen 30 and the shallower depth of field, facilitating viewing of the content displayed on the display screen 30. Furthermore, the thickness t of the light-transmitting part 22 can be 0.4mm, 0.7mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, etc., and this embodiment does not make a specific limitation on it.

[0090] As an optional implementation, the display housing 20 gradually bulges outwards towards the handle housing 10 to form an arc shape. This arc shape prevents water from flowing towards the display housing 20 when the electric toothbrush 100 is used, thus preventing water from adhering to the light-transmitting portion 22 and affecting the user's viewing of the content displayed on the screen 30.

[0091] As an alternative implementation, the display housing 20 has a flat surface facing the handle housing 10 and a peripheral surface connected to the flat surface, the peripheral surface being configured as an arcuate surface that gradually bulges towards the handle housing 10. Thus, by the display housing 20 gradually bulging towards the handle housing 10 to form an arcuate shape, when the electric toothbrush 100 is used, this arcuate shape can prevent water from flowing towards the display housing 20, thereby preventing water from adhering to the light-transmitting portion 22 and affecting the user's viewing of the content displayed on the display screen 30.

[0092] In some embodiments, the mounting portion 21 is provided with a support portion 21a, and the display screen 30 abuts against the support portion 21a. The support portion 21a includes a support column and / or a support platform. Thus, by providing the support portion 21a in the mounting portion 21, and utilizing the abutment between the support portion 21a and the display screen 30, the display screen 30 is supported, facilitating the installation of the display screen 30. Furthermore, various support portions 21a with different structures are provided, which can be selected according to actual needs; this embodiment does not impose a specific limitation on this.

[0093] For example, a buffer (not shown) is provided between the support portion 21a and the display screen 30. In this way, by providing a buffer between the support portion 21a and the display screen 30, the display screen 30 can be stably mounted on the support portion 21a during assembly, and the display screen 30 can be prevented from shifting relative to the support portion 21a when the electric toothbrush 100 is subjected to external forces such as collisions or drops.

[0094] Optionally, the display screen 30 is provided with an electrical connector 50 that is electrically connected to the mechanism 40, and the electrical connector 50 is partially pressed between the support portion 21a and the buffer member. In this way, by pressing the electrical connector 50 partially between the support portion 21a and the buffer member, the electrical connector 50 can be constrained, reducing the shaking of the electrical connector 50 and preventing the electrical connector 50 from interfering with other components. For example, it can prevent the electrical connector 50 from rubbing against the display screen 30 and causing damage to the display screen 30.

[0095] In some embodiments, the mounting part 21 is provided with a mounting groove 21b, and the display screen 30 is at least partially located in the mounting groove 21b. In this way, the mounting groove 21b accommodates at least part of the display screen 30, providing installation space, making the overall structure of the electric toothbrush 100 more compact while protecting the display screen 30.

[0096] For example, combined Figure 2 As shown, the display surface 30a of the display screen 30 is bonded to the light-transmitting part 22 with a light-transmitting adhesive. In this way, on the one hand, the installation stability of the display screen 30 can be improved by bonding the display screen 30 to the light-transmitting part 22 with the light-transmitting adhesive; on the other hand, by utilizing the light-transmitting property of the light-transmitting adhesive, the user can view the content displayed on the display screen 30 through the light-transmitting part 22 and the light-transmitting adhesive.

[0097] Optionally, the light-transmitting adhesive covers at least the display area of ​​the display surface 30a. This ensures that the light-transmitting adhesive covers at least the display area of ​​the display surface 30a, resulting in a larger coverage area and better installation stability of the display screen 30.

[0098] In some embodiments, such as Figure 2 and Figure 6As shown, the handle housing 10 includes a main body 11 and a support 12. The support 12 is located on one side of the main body 11 and protrudes from the main body 11. The display housing 20 is located on the support 12. In this way, on the one hand, by having the support 12 located on one side of the main body 11 and the display housing 20 located on the main body 11 via the support 12, the display housing 20 and the handle housing 10 are fixed together. On the other hand, by having the support 12 protrude from the main body 11 and the display housing 20 protrude from the handle housing 10, when the electric toothbrush 100 is used, water can be prevented from flowing from the handle housing 10 to the display housing 20, thereby preventing water from adhering to the light-transmitting part 22 and affecting the user's viewing of the content displayed on the display screen 30.

[0099] For example, the support portion 12 has a stepped portion 12a at one end facing the display housing 20, and the stepped portion 12a abuts against the display housing 20. In this way, the stepped portion 12a provides support, and the display housing 20 can be pre-positioned during assembly, reducing the assembly difficulty.

[0100] Optionally, a seal (not shown) is provided between the display housing 20 and the stepped portion 12a. In this way, waterproofing can be achieved by providing a seal between the display housing 20 and the stepped portion 12a.

[0101] For example, the support portion 12 has a first side surface 121 and a second side surface 122 connected together. The outer side surface of the display shell 20 abuts against the first side surface 121, and the inner side surface of the display shell 20 abuts against the second side surface 122. In this way, by having the first side surface 121 abut against the outer side surface of the display shell 20 and the second side surface 122 abut against the inner side surface of the display shell 20, the abutment of multiple surfaces allows the support portion 12 to be in close contact with the display shell 20, achieving a sealed and waterproof effect.

[0102] Optionally, the portion of the support 12 that connects to the display housing 20 is configured as an arc shape with a cross-section that gradually increases from the main body 11 towards the display housing 20. By configuring the portion connecting the support 12 to the display housing 20 as an arc shape, when the electric toothbrush 100 is used, the arc shape, which gradually increases from the main body 11 towards the display housing 20, prevents water from flowing towards the display housing 20, thereby preventing water from adhering to the light-transmitting portion 22 and affecting the user's viewing of the content displayed on the screen 30.

[0103] In some embodiments, such as Figure 4As shown, the outer surface of the support portion 12 is inclined to the outer surface of the main body portion 11, forming an included angle α, where 30° ≤ α < 90°. This inclination between the outer surface of the support portion 12 and the outer surface of the main body portion 11, i.e., the included angle α < 90°, prevents water from flowing towards the support portion 12 and subsequently towards the display screen 30. If the included angle α < 30°, the inclination between the outer surface of the support portion 12 and the outer surface of the main body portion 11 is smaller, resulting in a less effective prevention of water flow towards the support portion 12. Therefore, an included angle α of 30° ≤ α < 90° effectively prevents water from flowing towards the support portion 12 and subsequently towards the display screen 30. Furthermore, the included angle α can be 30°, 45°, 60°, 75°, 89°, etc., and this embodiment does not specifically limit this value.

[0104] For example, the distance between the projection of the outer edge of the support portion 12 onto the first surface and the projection of the connection point between the support portion 12 and the main body portion 11 onto the first surface is d2, where d2 ≥ 2 mm. The first surface is the plane containing the display surface 30a of the display screen 30. Thus, by forming a distance d2 between the outer edge of the support portion 12 and the connection point between the support portion 12 and the main body portion 11, and with d2 ≥ 2 mm, a relatively large distance is formed, which can minimize the possibility of water flowing towards the support portion 12 and subsequently towards the display screen 30. Furthermore, the distance d2 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc., and this embodiment does not specifically limit it.

[0105] In some embodiments, the projection of the outer contour of the display screen 30 onto the support portion 12 is located within the outer contour of the support portion 12. In this way, by placing the display screen 30 within the outer contour of the support portion 12, the support portion 12 can wrap around the display screen 30 and form a stepped contact structure to support and protect the display screen 30.

[0106] For example, the peripheral side of the display screen 30 is spaced apart from the inner side of the support portion 12. In this way, by spaced apart from the inner side of the support portion 12, interference between the display screen 30 and the support portion 12 can be avoided, and the support portion 12 can be prevented from obstructing the display screen 30.

[0107] In some embodiments, the electric toothbrush 100 also includes a light-shielding member (not shown), which is disposed on the side of the light-transmitting portion 22 facing or away from the display screen 30, and the light-shielding member at least covers the non-display area of ​​the display screen 30. In this way, by blocking the non-display area of ​​the display screen 30 with the light-shielding member, the user can focus on viewing the display area of ​​the display screen 30, and the user can better view the content displayed on the display screen 30, resulting in a better viewing experience.

[0108] In some embodiments, see again Figure 1 and Figure 2 The electric toothbrush 100 also includes a brush head 60, which is disposed in the handle housing 10. The motor 40 includes a servo motor 42, which is disposed inside the handle housing 10. The servo motor 42 is used to drive the brush head 60 to vibrate electrically. In this way, the servo motor 42 drives the brush head 60 to vibrate, and when the brush head 60 acts on the user's mouth, it can clean the user's mouth with better cleaning effect.

[0109] For example, the servo motor 42 is positioned opposite and spaced apart from the display screen 30. In this way, by separating the servo motor 42 from the display screen 30, the vibration generated by the servo motor 42 when driving the brush head 60 to vibrate can be prevented from affecting the display screen 30.

[0110] Optionally, the distance between the servo motor 42 and the display screen 30 is d, where d ≥ 3mm. This relatively large distance d minimizes the impact of vibrations generated by the servo motor 42 on the display screen 30. Furthermore, the distance d between the servo motor 42 and the display screen 30 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc., and this embodiment does not impose a specific limitation on this.

[0111] This utility model embodiment provides an electric toothbrush 100. A display housing 20 has a mounting portion 21 disposed around the handle housing 10. A light-transmitting portion 22 is disposed on the mounting portion 21, and is positioned away from the handle housing 10 relative to the mounting portion 21. This allows the display screen 30 to be mounted on the light-transmitting portion 22, with the display surface 30a of the display screen 30 closely fitted to the light-transmitting portion 22. This results in a shallow depth of field, making it easier for the user to view the content displayed on the display screen 30, and reducing the obstruction of the view by the handle housing 10. Furthermore, a mechanism 40 is housed inside the handle housing 10, which is electrically connected to the display screen 30 to drive its operation.
