[0053] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] It should be noted that, in the description of this application, if the terms "first", "second", etc. appear, "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" appears in the full text, its meaning is to include three parallel solutions. Taking "A and / or B as an example", it includes Solution A, or Solution B, or a solution that satisfies both A and B.

[0055] Please refer to Figures 1 to 5 as well as Figure 11 The present invention provides an electric toothbrush comprising a toothbrush body 100 and a base 60. The outer wall of the toothbrush body 100 is generally cylindrical, and the base 60 has a storage cavity 61. The storage cavity 61 has a cavity wall that fits snugly with the outer wall of the toothbrush body 100. A suction structure is provided between the toothbrush body 100 and the base 60. The suction structure allows the toothbrush body 100 and the base 60 to adhere to each other, so that the outer wall of the toothbrush body 100 fits snugly with the cavity wall of the storage cavity 61.

[0056] In the embodiment of the present application, the base 60 can be fixed to the wall, for example, by bonding or screwing. The toothbrush body 100 can be adsorbed onto the base 60 via an adsorption structure, so that the toothbrush body 100 appears suspended. The bottom of the toothbrush body 100 can be separated from the countertop to prevent water accumulation and reduce the possibility of mold growth. In addition, the outer wall of the toothbrush body 100 can match the storage cavity 61 of the base 60, resulting in a larger contact area between the toothbrush body 100 and the base 60, and the base 60 provides good support and stability for the toothbrush itself.

[0057] The adsorption structure refers to a magnetic structure. There are various ways to achieve adsorption between the toothbrush body 100 and the base 60 using the adsorption structure. In the first embodiment, the adsorption structure is provided on the base 60, and the outer wall of the toothbrush body 100, i.e., the handle housing 30, is made of metal. This metal outer wall can be directly magnetically attracted by the adsorption structure, thereby allowing the outer wall of the toothbrush body 100 to adhere to the cavity wall of the base 60. Specifically, the entire outer wall of the toothbrush body 100 can be made of metal, or a portion of the outer wall of the toothbrush body 100 can be made of metal, while the rest of the outer wall can be made of plastic.

[0058] In the second embodiment, the suction structure is mounted on the toothbrush body 100, and the portion of the base 60 that contacts the outer wall of the toothbrush body 100 is made of metal. Specifically, the walls of the storage cavity 61 of the base 60 are made of metal, while the rest of the base 60 can be made of metal or plastic. Using metal for the walls of the storage cavity 61 makes it easier to attach the toothbrush body 100 to the cavity wall.

[0059] In the third embodiment, the adsorption structure includes a first magnetic member 40 and a second magnetic member 62. The first magnetic member 40 is disposed on the toothbrush body 100, and the second magnetic member 62 is disposed on the base 60. In this embodiment, when the toothbrush body 100 is brought close to the base 60, an attractive force is generated between the first magnetic member 40 and the second magnetic member 62, thereby adsorbing the toothbrush body 100 to the base 60. Due to the presence of the first magnetic member 40 and the second magnetic member 62, the material of the outer wall of the toothbrush body 100 and the base 60 is not limited; both can be made of plastic or other materials.

[0060] When the first magnetic component 40 is provided on the toothbrush body 100 , the first magnetic component 40 can be provided on the inner wall of the handle housing 30 , that is, directly fixed to the handle housing 30 ; or, the first magnetic component 40 can also be provided on other structures inside the handle housing 30 .

[0061] Specifically, in some embodiments, please refer to Figures 1 to 5The toothbrush body 100 includes: a motor body 10, a motor bracket 20, a handle housing 30 and a first magnetic component 40; the motor bracket 20 serves as a protective and fixing component of the motor body 10, the motor bracket 20 is sleeved on the outside of the motor body 10 and fixed to the motor body 10, and the first magnetic component 40 is fixed to the outer side of the motor bracket 20.

[0062] Furthermore, the handle housing 30 includes a metal shell 31 and a plastic part 32. The metal shell 31 is cylindrically arranged to accommodate the motor body 10 and the motor bracket 20. The inner wall of the metal shell 31 includes a first area 311 ( Figure 5 The first magnetic member 40 is fixed to the outer side of the motor bracket 20 and is located between the motor bracket 20 and the second region 312.

[0063] Due to the limitations of the metal shell 31's processing methods, such as stamping or bending, it is generally difficult to form complex structures on the metal shell 31. Furthermore, the metal shell 31 is typically formed from a sheet of uniform thickness, with the thickness being essentially consistent across the entire structure. To create complex structures or ribs on the metal shell 31, which would result in significant thickness variations, requires using thicker sheet metal and removing material in certain areas. This leads to the following problems: First, thicker sheet metal is more difficult to process and therefore more expensive; second, the removal process results in significant material waste.

[0064] To address this, the handle housing 30 in the embodiment of the present application adopts a combination of a metal shell 31 and a plastic part 32. A relatively thin plate material can be used to form the metal shell 31. The metal shell 31 has greater strength than the plastic shell, and can provide better protection for the internal motor body 10 and other structures. In addition, the thinner metal shell 31 has a lighter weight, which brings a better feel. The plastic part 32 is attached to the inner wall of the metal shell 31 by one-piece injection molding, and the two can be tightly fitted without the need for additional installation. In addition, the plastic part 32 can form a more complex limiting structure to limit the motor bracket 20, and the one-piece injection molding method facilitates the one-piece molding of the limiting structure, reducing the difficulty of molding.

[0065] The handle housing 30 has a greater thickness where the plastic member 32 is located. This portion provides greater overall strength, better positioning of the motor bracket 20. The greater thickness also reduces the possibility of deformation caused by compression when mating with the motor bracket 20. Where the plastic member 32 is not located, the handle housing 30 has a smaller thickness, effectively creating a space within the handle housing 30 for the installation of the first magnetic member 40. This space is effectively utilized, resulting in a more compact structure.

[0066] When the electric toothbrush 100 adopts the first magnetic part 40, the electric toothbrush 100 can use the first magnetic part 40 to match with the magnetic wall mount, so that the electric toothbrush 100 is suspended in the air, and the bottom of the electric toothbrush 100 can be separated from the table to avoid water accumulation, reducing the possibility of mold growth.

[0067] Optionally, the first region 311 and the second region 312 have the same wall thickness.

[0068] Please refer to Figure 8 In some embodiments, a mounting groove 21 is formed on the outer side of the motor bracket 20 facing the second area 312, and the first magnetic component 40 is embedded in the mounting groove 21. In this way, the first magnetic component 40 is limited by the mounting groove 21, which can reduce the risk of the first magnetic component 40 being hit on all sides and detached from the motor bracket 20. In this embodiment, the first magnetic component 40 is embedded in the mounting groove 21, which means that the shapes of the two are adapted, and there is a small gap or interference fit between the two. For example, the first magnetic component 40 is square and the mounting groove 21 is also square. Optionally, the first magnetic component 40 is bonded and fixed to the motor bracket 20, which can further prevent the first magnetic component 40 from detaching from the motor bracket 20. Of course, in other embodiments, a plurality of protrusions can also be provided on the motor bracket 20 to abut and limit the first magnetic component 40.

[0069] In some embodiments, the outer side of the motor bracket 20 is provided with a rib 22, which extends to form a structure connected end to end to enclose the mounting groove 21. If the mounting groove 21 is formed by directly cutting a groove on the outer side of the motor bracket 20, the entire motor bracket 20 needs to be thicker to ensure strength, resulting in increased processing cost and difficulty. In this embodiment, the rib 22 is used to enclose the mounting groove 21, and the entire motor bracket 20 can be thinner. The rib 22 acts as a reinforcing rib to strengthen the structure of the motor bracket 20, thereby providing a stable fixing effect on the first magnetic member 40.

[0070] In some embodiments, the motor bracket 20 includes an arc-shaped wall disposed circumferentially around the motor body 10, such as Figure 9As shown, the first magnetic member 40 is curved and fits snugly against the curved wall. The motor body 10 is typically cylindrical, and the motor bracket 20 is sleeved outside the motor body 10. To optimize space utilization, the motor bracket 20 is also generally cylindrical with a curved wall. The curved shape of the first magnetic member 40 allows it to fit snugly against the curved wall, ensuring that the first magnetic member 40 has a larger surface area to generate a greater magnetic force while also optimizing space utilization.

[0071] Please refer to Figure 6 and Figure 7 In some embodiments, the plastic component 32 includes a cylindrical body 321 and two extension walls 322. The cylindrical body 321 is positioned at the end of the metal shell 31 and circumferentially extends around the metal shell 31. The extension walls 322 extend axially from the metal shell 31 and are connected to the cylindrical body 321 at one end. The two extension walls 322 are spaced apart circumferentially around the cylindrical body 321, and retaining structures are provided on the extension walls 322. In this embodiment, the cylindrical body 321 serves to secure the two extension walls 322 as a single unit, facilitating uniform positioning during injection molding. Furthermore, the inner wall of the cylindrical body 321 can also be formed with more complex mounting and positioning structures, such as various ribs or grooves to retain the waterproof silicone sleeve at the end of the handle. The shape of the cylindrical body 321 can match the shape of the handle end, for example, a spherical shell. When the metal shell 31 is cylindrical, the extension walls 322 are generally curved to conform to the curved inner wall of the metal shell 31.

[0072] Please refer to it again Figure 4 and Figure 10 Furthermore, the electric toothbrush 100 further includes a main control board 50, which is fixed to the outer side of the motor bracket 20 and extends axially along the handle housing 30. The main control board 50 and the first magnetic member 40 are located on opposite sides of the motor bracket 20, each corresponding to a gap G between the two extension walls 322. Specifically, two gaps G are formed between the two extension walls 322, with the main control board 50 located in one gap G and the first magnetic member 40 located in the other gap G, effectively utilizing space.

[0073] In some embodiments, the rib 22 and a portion of the first magnetic member 40 extend into the gap G between the two extension walls 322, that is, the rib 22 and a portion of the first magnetic member 40 are located in the gap G, making full use of the space of this portion of the gap G and improving the compactness of the structure.

[0074] Optionally, a portion of the main control board 50 also extends into another gap G between the two extension walls 322 .

[0075] In some embodiments, the limiting structure includes a plurality of limiting ribs 323, which are spaced apart along the circumference of the metal shell 31 and extend axially along the metal shell 31. The outer side of the motor bracket 20 is also provided with a positioning rib 23, which is clamped between two adjacent limiting ribs 323. During installation, the motor bracket 20 and the motor body 10 are pushed upward from the bottom of the metal shell 31 into the interior of the metal shell 31. The positioning rib 23 cooperates with the limiting groove formed between the two adjacent limiting ribs 323 to guide the motor bracket 20 to slide from bottom to top. When the motor bracket 20 slides into place, the positioning rib 23 and the limiting groove are clamped to prevent the motor bracket 20 from rotating circumferentially.

[0076] In other embodiments, Figure 3 、 Figure 16 and Figure 17 As shown, the toothbrush body 100 includes a handle shell 30, a motor body 10 and a motor bracket 20; the handle shell 30 is cylindrical, and the motor body 10 and the motor bracket 20 are installed in the handle shell 30; the motor bracket 20 is sleeved on the outside of the motor body 10; the first magnetic component 40 is fixedly connected to the motor body 10 and / or the motor bracket 20, and the first magnetic component 40 is at least partially exposed on the outer wall of the motor bracket 20 and is arranged corresponding to the second magnetic component 62.

[0077] In this embodiment, the handle housing 30 can be configured as a single-layer shell or a double-layer shell, for example, a double-layer shell structure with an inner layer of plastic and an outer layer of metal, which is not specifically limited here. It can be understood that the handle housing 30 as a whole is a long cylindrical structure to facilitate the user's hand-held grip. The motor bracket 20 can be fixedly connected to the handle housing 30, or it can be fixedly connected to the bottom cover of the toothbrush body 100. The fixing method of the motor bracket 20 is not specifically limited here. The motor body 10 can be fixedly connected to the motor bracket 20. Of course, in some embodiments, the motor body 10 can also be fixed to other structures such as end covers.

[0078] The first magnetic member 40 and the second magnetic member 62 can be permanent magnets. Positioning the first magnetic member 40 on the motor body 10 and / or the motor bracket 20 facilitates securing and assembling the first magnetic member 40, compared to positioning the first magnetic member 40 on the inner wall of the handle housing 30. During installation, the first magnetic member 40 only needs to be secured to the motor body 10 and / or the motor bracket 20. The first magnetic member 40 can then be installed within the handle housing 30 along with the motor body 10, the motor bracket 20, and other components.

[0079] The first magnetic component 40 can be fixed to the motor body 10. In this case, it is necessary to open a revealing window 24 on the motor bracket 20 so that the first magnetic component 40 can be exposed on the motor bracket 20. Of course, the first magnetic component 40 can also be fixed only to the motor bracket 20. It is only necessary to make the first magnetic component 40 partially exposed on the outer wall of the motor bracket 20 and set corresponding to the second magnetic component 62. Making the first magnetic component 40 at least partially exposed on the outer wall of the motor bracket 20 and set corresponding to the second magnetic component 62 can avoid the wall thickness of the motor bracket 20 weakening the adsorption force of the first magnetic component 40 and the second magnetic component 62. The first magnetic component 40 is set corresponding to the second magnetic component 62 in the thickness direction of the handle shell, which can ensure the magnetic attraction of the two.

[0080] For further information, please refer to Figure 17 The first magnetic member 40 at least partially protrudes from the outer wall of the motor bracket 20 and is disposed adjacent to the inner wall of the handle housing 30. This allows the outer wall of the first magnetic member 40 to fit more closely with the second magnetic member 62, shortening the distance between the two and further ensuring the magnetic attraction between the two, thereby preventing the toothbrush body 100 from falling off the base 60.

[0081] Furthermore, the motor bracket 20 is provided with a revealing window 24 corresponding to the second magnetic member 62 . The second magnetic member 62 is fixedly connected to the motor body 10 and is revealed from the motor bracket 20 through the revealing window 24 .

[0082] In this embodiment, the second magnetic member 62 can be fixedly attached to the outer peripheral wall of the motor body 10, for example, by glue bonding, foam bonding, etc. By opening a revealing window 24 on the motor bracket 20, the second magnetic member 62 is fixed to the motor body 10 and exposed to the motor bracket 20 through the revealing window 24. Then, the inner peripheral wall of the revealing window 24 can limit the second magnetic member 62, thereby preventing the second magnetic member 62 from falling off due to failure of the connection with the motor body 10 caused by gravity. Compared with the method of providing ribs on the outer peripheral wall of the motor bracket 20 to enclose and form a mounting groove, the structure of the motor bracket 20 can be simplified, the lateral space occupied by the motor bracket 20 can be reduced, and the outer diameter of the handle housing 30 can be set smaller, which is more conducive to the miniaturization of the toothbrush body 100.

[0083] In one embodiment, if Figure 16 and Figure 17As shown, the first magnetic member 40 and the second magnetic member 62 are both arranged in a strip shape along the length of the toothbrush body 100. This arrangement fully utilizes the space along the length of the toothbrush body 100 to arrange the first magnetic member 40. Compared to configuring the first magnetic member 40 as an arc-shaped structure extending radially along the toothbrush body 100, the effective adsorption area of the first magnetic member 40 and the second magnetic member 62 can be increased, and the radial dimension of the toothbrush body 100 can be set to be smaller, thereby further facilitating miniaturization of the toothbrush body 100.

[0084] In one embodiment, please refer to Figure 3 、 Figure 15 and Figure 17 A button 33 is provided on the outer wall of the toothbrush body 100 , and the base 60 is adsorbed and attached to the outer wall of the toothbrush body 100 relative to the button 33 through an adsorption structure.

[0085] In this embodiment, the button 33 on the outer wall of the toothbrush body 100 can have many different structures. For example, the outer wall of the toothbrush body 100 can be partially recessed to form the button 33, or a mounting hole can be provided on the outer wall of the toothbrush body 100 and a button can be installed in the mounting hole to form the button 33. The specific structure of the button 33 is not limited herein. Typically, the wall of the toothbrush body 100 on which the button 33 is provided is the front surface, and the wall of the toothbrush body 100 opposite the button 33 is the back surface. By having the base 60 adhere to the outer wall of the toothbrush body 100 opposite the button 33 via an adsorption structure, that is, having the back surface of the toothbrush body 100 adsorbed to the base 60, the user can effectively avoid accidentally touching the button 33 when removing the toothbrush body 100 from the base 60, and the user's usage habits are more in line with the user's usage habits.

[0086] In some embodiments, the base 60 includes a first surface 611 and a second surface 612 that are opposed to each other. The first surface 611 is a flat surface to facilitate contact with a wall, and the second surface 612 is a concave arc surface to enclose and form a storage cavity 61. The second magnetic member 62 is located within the base 60 and has an arc-shaped structure. The second magnetic member 62, the second surface 612, and the first magnetic member 40 are arranged in parallel. The outer contour of the cross-section of the handle housing 30 is an outwardly convex arc, and a portion of the handle housing 30 is embedded in the cavity formed by the concave arc surface.

[0087] In this embodiment, parallel means parallel or substantially close to parallel, that is, the bending curvature and bending direction of the second magnetic member 62, the second surface 612 and the first magnetic member 40 are substantially the same, so that the second magnetic member 62 and the first magnetic member 40 have a larger mutually coordinated magnetic attraction area, and also enable the second magnetic member 62 to reasonably utilize the curved shape of the second surface 612.

[0088] The cross-section of the handle housing 30 refers to a cross-section perpendicular to the handle axis. The handle housing 30 can be generally circular, oval, or approximately circular. The handle housing 30 is adapted to the concave arc surface, thereby providing a large contact area between the handle housing 30 and the base 60, and the base 60 has a certain limiting effect on the handle housing 30.

[0089] Of course, in other embodiments, the second surface 612 may also be a flat surface, and the first magnetic member 40 and the second magnetic member 62 may be a flat magnet.

[0090] like Figures 12 to 14 As shown, in some embodiments, an extension portion 64 protrudes from one side of the base 60, and the storage cavity 61 is set through the extension portion 64. For example, the base 60 can be formed by combining a base 63 and an extension portion 64, the base 63 and the extension portion 64 are distributed in the horizontal direction, and the storage cavity 61 passes through the extension portion 64 from top to bottom. Figure 12 As shown, the base 63 and the extension 64 can be square, and the length and width of the base 63 are larger than the length and width of the extension 64. Figure 13 As shown, the base 63 may be semicircular and the extension 64 may be in an incomplete circle, with the radius of the base 63 being larger than the radius of the extension 64. Of course, the size of the base 63 may also be smaller than the size of the extension 64. One side of the base 63 is fixed to the wall, and the extension 64 is provided with a storage cavity 61 for inserting the toothbrush body 100. Figure 12 and Figure 13 As shown, the storage cavity 61 can be a semicircular hole; or, as shown Figure 14 As shown, the storage cavity 61 can be a complete circular hole or a shape similar to a circular hole.
