Description

An embedded magnetic structure for a razor Technical Field

[0001] This utility model provides a shaving tool, specifically a razor with a concealed magnetic structure. Background Technology

[0002] Electric shavers are common power tools that use a reciprocating or rotating electric blade assembly to clean facial hair. Below the blade assembly is a dustbin where stubble accumulates and requires regular cleaning. Therefore, both the blade assembly and the dustbin must be designed with a highly reusable, detachable structure. Current technologies typically use mechanical connections such as snap-fit ​​mechanisms or push-button switches, which can loosen over time. Magnetic structures based on magnet attraction are also available. Compared to traditional connections, the magnets in magnetic structures are located inside the shaver, resulting in a smooth, unexposed exterior that is aesthetically pleasing and easy to use. However, to enhance magnetism and ease of installation, current technologies often expose the magnets to the atmosphere during stubble cleaning, allowing them to come into contact with dust or water, affecting their magnetism and reducing the stability of the magnetic structure.

[0027] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] As shown in Figures 1 and 2, a concealed magnetic structure for a shaver includes a shaver body 1 and a cover 2 that covers the upper part of the shaver body 1. A blade assembly 22 and a first magnetic element 23 are installed inside the cover 2. A drive unit 12 and a second magnetic element 13 are installed inside the shaver body 1. The first magnetic element 23 and the second magnetic element 13 attract each other, fixing the relative position of the cover 2 and the shaver body 1. When the cover 2 is closed on top of the shaver body 1, the drive unit 12 and the blade assembly 22 are connected as a whole. After the power is turned on, the drive unit 12 drives the blade assembly 22 to work.

[0029] Specifically, the shaver body 1 includes a lower housing 11 with an opening at its upper end. A lower fixing seat 14 is installed inside the opening, and the lower fixing seat 14 is recessed in the middle to form a dustbin 141 for accommodating beard hairs. The second magnetic attractor 13 consists of two sets of circular magnets, disposed inside the lower fixing seat 14 and positioned on both sides of the dustbin 141. The second magnetic attractor 13 is isolated from the dustbin 141 and will not be contaminated or have its magnetism affected by the beard hairs inside the dustbin 141. Below the lower fixing seat 14, a drive unit 12 and components such as a battery that power the drive unit 12 are stored. The drive shaft of the drive unit 12 extends from the middle of the dustbin 141. The lower fixing seat 14 is divided into a drive area in the middle and magnetic attractor areas on both sides.

[0030] It should be noted that the second magnetic component 13 is not limited to a round magnet; magnets of other shapes can also achieve the magnetic attraction effect.

[0031] As shown in Figure 3, in this embodiment, the upper fixing base 24 consists of a first part 142 and a second part 143 arranged opposite to each other. Connecting holes 144 are respectively provided at corresponding positions on the first part 142 and the second part 143. Connectors are inserted into the connecting holes 144 to fix the first part 142 and the second part 143 together. The first part 142 and the second part 143 form a split structure. The second magnetic suction member 13 is disposed on the second part 143, and the second part 143 provides bottom support for the second magnetic suction member 13. The first part 142 covers the top of the second part 143. The garbage bin 141 is opened on the upper surface of the first part 142, and a lower magnet groove 145 is opened on the lower surface of the first part 142 to accommodate the second magnetic suction member 13. The shape of the lower magnet groove 145 is approximately the same as that of the second magnetic suction member 13. When the first part 142 is connected to the second part 143, the second magnetic suction member 13 is hidden within the lower magnet groove 145, thereby limiting the position of the second magnetic suction member 13. As a further embodiment of this utility model, the lower magnet groove 145 is positioned close to the upper surface of the first part 142 to reduce the distance between the second magnetic attractor 13 and the upper surface of the first part 142, thereby reducing the impact of the implicit structure on the magnetic connection.

[0032] As shown in Figures 4 and 6, the cover 2 includes an upper shell 21 and an upper fixing seat 24 installed inside the upper shell 21. The upper shell 21 is sealed to the lower shell 11. The upper fixing seat 24 is used to fix the positions of the blade assembly 22 and the first magnetic suction member 23. Specifically, the upper fixing seat 24 is roughly a rectangular frame, enclosed by a base plate 242 and side plates 243. The upper part of the base plate 242 is the placement area for the blade assembly 22. An opening is provided in the middle of the base plate 242 corresponding to the position of the waste trough 141, allowing the drive shaft of the drive unit 12 to extend into, connect with the blade assembly 22, and drive the blade assembly 22. Upper magnet slots 241 for accommodating the first magnetic suction member 23 are provided on both sides of the upper fixing seat 24 corresponding to the positions of the second magnetic suction member 13. The slots of the upper magnet slots 241 extend out from both sides of the upper fixing seat 24, and the first magnetic suction member 23 is inserted from the slots of the upper magnet slots 241. The shape of the upper magnet slot 241 is set according to the shape of the first magnetic member 23 to stabilize the position of the first magnetic member 23. In this embodiment, the first magnetic member 23 is preferably a block magnet, which can be easily inserted into the upper magnet slot 241 and stabilize the position of the first magnetic member 23.

[0033] As a further embodiment of the present invention, a positioning post 244 is provided on the upper surface of the base plate 242 for engaging with the positioning hole at the bottom of the cutter head assembly 22. The positioning post 244 extends into the positioning hole and fixes the cutter head assembly 22 above the base plate 242 by means of pin engagement.

[0034] In this embodiment, the cutter head assembly 22 consists of two sets of reciprocating cutter heads arranged side by side in the upper mounting base. Each cutter head is composed of multiple blades forming a blade mesh structure. The bottom of the cutter head assembly 22 is provided with a transmission structure connected to the drive shaft of the drive unit 12, which drives it to move reciprocally in a straight line.

[0035] As a further embodiment of the present invention, the blade assembly 22 is connected to the upper fixed base 24 by a snap fastener. A first snap fastener 221 protrudes from the side of the blade assembly 22, and a first snap groove 245 is provided on both sides of the side plate 243 corresponding to the position of the first snap fastener 221. The first snap fastener 221 engages with the first snap groove 245, thereby positioning the blade assembly 22 laterally.

[0036] As a further embodiment of this utility model, the upper fixing seat 24 and the upper housing 21 are also connected by a snap fastener. Second snap fasteners 246 protrude outwards from both sides of the side plate 243. A second snap groove 211 is provided on the inner side of the upper housing 21 corresponding to the position of the second snap fasteners 246. The second snap fasteners 246 engage with the second snap groove 211, thus fixing the upper fixing seat 24 to the inner side of the upper housing 21. After assembly, the inner wall of the upper housing 21 is located outside the upper magnet groove 241, naturally closing the opening of the upper magnet groove 241 and fixing the position of the second magnetic component 13.

[0037] The shaver body 1 and the cover 2 of this invention are magnetically connected. When the upper opening of the cover 2 is opened, the upper part of the shaver head assembly 22 extends out of the upper opening of the cover 2. After the cover 2 is closed, the drive unit 12 connects to the lower part of the shaver head assembly 22, activating the power to clean the face. After use, the cover 2 is opened to rinse and clean the beard in the dustbin 141. To further prevent the upper part of the shaver head assembly 22 from being exposed to air and accumulating dust for extended periods, as shown in Figure 5, this invention also includes a cap 3. When not in use, the cap 3 covers the upper part of the cover 2, isolating the shaver head assembly 22 from the atmosphere. A third magnetic element 31 is installed inside the cap 3, also using a magnetic structure to connect with the cover 2. This design reduces the use of screws and other connecting parts, resulting in a more consistent and cleaner appearance for the entire shaver.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
