Description

Technical Field

[0001] This utility model relates to the technical field of electric toothbrush accessories, specifically a charging base for an electric toothbrush. Background Technology

[0002] Electric toothbrushes are widely used in daily life due to their convenience and good cleaning effect. The charging base, as the core accessory of electric toothbrushes, is responsible for charging the toothbrush and providing support for its placement.

[0003] The existing patent document CN222676510U discloses a charging base for an electric toothbrush. The charging body of this utility model is protected by a shell that can be quickly detached and connected. When it is necessary to remove the charging body, the shell can be removed, and the charging body can also be used independently.

[0004] However, the existing charging bases for electric toothbrushes have a simple positioning structure and poor stability. The existing charging bases rely on simple grooves or flat surfaces for positioning, which cannot accurately fix electric toothbrushes of different sizes and shapes. In daily use, the toothbrush is prone to shifting or tipping over due to slight touch or table vibration, resulting in poor charging contact and frequent interruption of the charging process. This not only affects the efficiency of use, but also shortens the battery life. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide a charging base for electric toothbrushes to solve the problems mentioned in the background art, such as the simple positioning structure and poor stability of existing charging bases for electric toothbrushes.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a charging base for an electric toothbrush, including a support base, the support base being disc-shaped and made of insulating and flame-retardant ABS engineering plastic, with a central positioning column vertically arranged in the middle of the upper surface of the support base;

[0009] The central positioning post has a frustum-shaped structure. A lower protective shell is arranged around the outer side of the central positioning post on the upper surface of the support base. The lower protective shell is cylindrical, and its inner wall is provided with symmetrically distributed elastic clamping arms. The elastic clamping arms are made of plastic material wrapped with silicone. An anti-slip pad is attached to the bottom of the support base.

[0010] As a further improvement to the above solution, a frustum-shaped sleeve is provided on the top of the lower protective shell. The frustum-shaped sleeve is a frustum shape that is narrower at the top and wider at the bottom, and an elastic guide plate is provided on its top.

[0011] As a further improvement to the above solution, the elastic guide plate is integrally molded from soft silicone material, and an opening is provided at the center of the elastic guide plate. An annular drainage groove is provided around the bottom of the outer side of the frustum-shaped sleeve.

[0012] As a further improvement to the above solution, the bottom of the drain trough is evenly provided with drainage holes, and the two sides inside the drain trough are symmetrically provided with fixing ears, and the fixing ears are provided with circular through holes.

[0013] As a further improvement to the above solution, an upper protective shell is provided above the lower protective shell, and a limiting ring that matches the drain groove is provided inside the upper protective shell.

[0014] As a further improvement to the above solution, the limiting ring is provided with connecting ears symmetrically arranged on both sides, the connecting ears correspond to the fixing ears, and the connecting ears are provided with vertical insertion posts.

[0015] As a further improvement to the above solution, the shape of the plug-in post matches the through hole on the fixing ear, allowing for movable insertion. A wireless charging coil is embedded inside the support base, and the wireless charging coil is connected to an external power source.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The charging base for this electric toothbrush achieves three-dimensional stable fixation of the electric toothbrush through the synergistic effect of the truncated cone-shaped central positioning post on the support base and four sets of symmetrically distributed silicone elastic clamping arms. The central positioning post precisely matches the positioning hole at the bottom of the toothbrush, and the elastic clamping arms provide flexible clamping force from the outside. Combined with the friction-enhancing design of the bottom anti-slip pad, a "point-surface-bottom" triple protection structure is formed, which effectively resists external vibration interference, improves the stability of charging contact, significantly reduces the risk of charging interruption due to shaking, and extends battery life.

[0018] 2. The charging base for this electric toothbrush features an elastic guide plate at the top of a frustum-shaped sleeve, an annular drainage groove, and drainage holes. After use, when the toothbrush head is inserted into the placement opening, residual water can quickly flow into the drainage groove along the inclined surface of the frustum-shaped sleeve and then be discharged through the evenly distributed drainage holes at the bottom. Compared with traditional bases without drainage or with simple drainage structures, this effectively prevents water from accumulating around the brush head, reducing bacterial growth. Furthermore, the upper and lower protective shells are detachably connected by a limiting ring, fixing ear, and plug-in post, facilitating regular disassembly and cleaning of the drainage groove, further ensuring hygiene during use.

[0019] 3. The charging base of this electric toothbrush has an elastic guide plate molded from soft silicone in one piece. The central opening can be used to adapt to different brands and models of electric toothbrushes, which is highly compatible. At the same time, the wireless charging coil is designed to eliminate the limitations of traditional contact charging on the position and shape of the charging contacts. As long as the electric toothbrush supports wireless charging, it can be used without distinguishing between specific models, thus reducing the user's cost. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a charging base for an electric toothbrush, including a support base 1, which is disc-shaped and made of insulating and flame-retardant ABS engineering plastic. A central positioning column 2 is vertically arranged in the middle of the upper surface of the support base 1.

[0028] The central positioning post 2 has a frustum-shaped structure. The upper surface of the support base 1 is surrounded by a lower protective shell 3 on the outside of the central positioning post 2. The lower protective shell 3 is cylindrical, and its inner wall is provided with symmetrically distributed elastic clamping arms 4. The elastic clamping arms 4 are made of plastic material wrapped with silicone. The bottom of the support base 1 is attached with an anti-slip pad 5.

[0029] The user aligns the electric toothbrush vertically with the central positioning post 2 on the support base 1. The positioning groove on the bottom of the toothbrush precisely matches the central positioning post 2 (a frustum-shaped structure) to achieve initial positioning. At this time, the four sets of symmetrically distributed silicone elastic clamping arms 4 open under the pressure of the toothbrush and use the rebound force to evenly clamp the toothbrush handle from four directions, forming a stable "surface contact" fixation. The anti-slip pad 5 at the bottom of the support base 1 simultaneously increases the friction with the table to prevent the base from sliding. During charging, if the toothbrush is shaken by external force (such as a collision) and its position shifts, the continuous rebound force of the elastic clamping arms 4 can automatically correct the position deviation to ensure stable charging contact.

[0030] The lower protective shell 3 has a frustum-shaped sleeve 6 on its top. The frustum-shaped sleeve 6 is narrower at the top and wider at the bottom. An elastic guide plate 7 is provided on its top. The elastic guide plate 7 is integrally molded from soft silicone material. An opening 8 is provided in the center of the elastic guide plate 7. An annular drainage groove 9 is provided around the bottom of the outer side of the frustum-shaped sleeve 6. Drainage holes 10 are evenly provided at the bottom of the drainage groove 9. Fixing ears 11 are symmetrically provided on both sides inside the drainage groove 9. A circular through hole is provided on the fixing ears 11. An upper protective shell 12 is provided above the lower protective shell 3. A limiting ring 13 that matches the drainage groove 9 is provided inside the upper protective shell 12. Connecting ears 14 are symmetrically provided on both sides inside the limiting ring 13. The connecting ears 14 correspond fully to the fixing ears 11. A plug-in post 15 is vertically provided on the connecting ears 14. The shape of the plug-in post 15 matches the through hole on the fixing ear 11 and can be movably plugged in. A wireless charging coil 16 is embedded inside the support base 1. The wireless charging coil 16 is connected to an external power source.

[0031] Once the toothbrush is securely placed using the positioning system, its bottom wireless charging receiver coil automatically aligns with the wireless charging coil 16 (output power 5W, compliant with Qi standard) inside the support base 1. When the system detects that the toothbrush's battery level is lower than the set value (e.g., 30%), the wireless charging module automatically starts, transmitting electrical energy through electromagnetic induction. When the toothbrush is inserted after use, the brush head first contacts the elastic guide plate 7 (with an inner diameter of φ18~24mm for the placement opening 8). The silicone guide plate adaptively deforms to guide the brush head into the frustum-shaped sleeve 6. Residual water flows along the inclined surface of the sleeve into the annular drain groove 9 and is quickly discharged through the bottom drain hole 10. Users can periodically disassemble the upper protective shell 12 (separated from the fixing ear 11 via the insertion post 15) to thoroughly clean the drain groove 9.

[0032] Working principle: The user vertically aligns the electric toothbrush with the central positioning post 2 on the support base 1. The positioning groove on the bottom of the toothbrush precisely engages with the central positioning post 2 (a frustum-shaped structure) to achieve initial positioning. At this time, four sets of symmetrically distributed annular silicone elastic clamping arms 4 open under the pressure of the toothbrush, using the rebound force to evenly clamp the toothbrush handle from four directions, forming a stable "surface contact" fixation. The anti-slip pad 5 on the bottom of the support base 1 simultaneously increases the friction with the table to prevent the base from sliding. After the toothbrush is securely placed by the positioning system, its bottom wireless charging receiving coil automatically aligns with the wireless charging coil 16 (output power 5W, compliant with Qi standard) inside the support base 1. The system detects that the toothbrush battery level is lower than the set value ( When the battery level reaches 30%, the wireless charging module automatically starts, transmitting electrical energy through electromagnetic induction. When the toothbrush is inserted after use, the brush head first contacts the elastic guide plate 7 (with an inner diameter of φ18~24mm for the placement opening 8). The silicone guide plate adaptively deforms to guide the brush head into the frustum-shaped sleeve 6. Residual water flows along the inclined surface of the sleeve into the annular drain groove 9 and is quickly discharged through the bottom drain hole 10. Users can periodically disassemble the upper protective shell 12 (separated from the fixing ear 11 via the plug post 15) to thoroughly clean the drain groove 9. During charging, if the toothbrush shifts position due to external force (such as collision), the continuous rebound force of the elastic clamping arm 4 can automatically correct the position deviation, ensuring stable charging contact.

[0033] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
