[0043] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0044] This embodiment provides a magnetic protective cover, such as Figures 1-3 As shown, it includes: a protective cover 1, a tray 2, and a magnetic component 3; wherein, the protective cover 1 has a receiving cavity 11 with a bottom opening; the tray 2 can be installed into the receiving cavity 11, forming an installation space between the tray 2 and the protective cover 1; the magnetic component 3 is installed inside the installation space.

[0045] When assembling the magnetic protective cover of this embodiment, the magnetic component 3 is first installed inside the installation space, and then the tray 2 is installed into the receiving cavity 11 and fixedly installed with the protective cover 1. When the protective cover 1 is closed on the shaver head, a magnetic attraction is generated between the magnetic component 3 and the shaver head, thereby tightly attracting the protective cover 1 and the shaver head together. Compared with traditional protective covers, the magnetic protective cover of this embodiment is less likely to loosen or fail to close properly even after long-term use; in addition, the protective cover 1 is attracted to the shaver head by the magnetic component 3, eliminating the need for a snap button, resulting in a simpler and smoother overall appearance.

[0046] The installation space is a first installation groove 12 formed on the inner top wall of the protective cover 1 and opening downward; or the installation space is a second installation groove 21 formed on the tray 2 and opening upward; or the installation space is formed by the first installation groove 12 formed on the inner top wall of the protective cover 1 and opening downward and the second installation groove 21 formed on the tray 2 and opening upward. When the magnetic protective cover is installed, the magnetic member 3 is installed in the second installation groove 21, and then the tray 2 is installed into the accommodating cavity 11, and a part of the top of the magnetic member 3 enters the first installation groove 12, so that the magnetic member 3 is fixed in position in the installation space.

[0047] The tray 2 is fixedly installed in the accommodating cavity 11 through a clamping structure; the clamping structure comprises clamping blocks 4 and clamping buckles 41; wherein the clamping blocks 4 are at least two and are fixedly arranged on the inner wall of the protective cover 1; the clamping buckles 41 are at least two and are fixedly arranged on the side wall of the tray 2 and are opposite to the clamping blocks 4 in position and can be clamped with the clamping blocks 4. Through the matching clamping of the clamping blocks 4 and the clamping buckles 41, the operation is simple and convenient when the tray 2 is installed or disassembled.

[0048] The clamping blocks 4 are four and are fixedly arranged on the two long side walls of the protective cover 1 respectively; the clamping buckles 41 are fixedly arranged on the two long side walls of the tray 2 respectively and can be clamped with the clamping blocks 4 in the corresponding positions. The arrangement of multiple sets of clamping blocks 4 and clamping buckles 41 increases the stability of the clamping between the tray 2 and the protective cover 1.

[0049] As a variant design scheme, as shown in Figure 5 The tray 2 is fixedly installed in the accommodating cavity 11 through a riveting structure; specifically, the riveting structure comprises riveting columns 7 and installation through holes 71; wherein the riveting columns are at least two and are integrally formed on the inner wall of the protective cover 1; the installation through holes 71 are at least two and are arranged on the tray 2 and are opposite to the riveting columns 7 in position; a limiting flange 72 is formed on the inner wall of the installation through hole 71; the riveting columns 7 can be fixedly connected with the installation through holes 71 through riveting, so as to fixedly install the tray 2 in the accommodating cavity 11. Specifically, the riveting column 7 is made of plastic material, the tray 2 is installed into the accommodating cavity 11 during assembly, the installation through hole 71 passes through the riveting column 7, and then a hot-pressing device is used to perform hot-pressing operation on the free end of the riveting column 7 extending out of the installation through hole 71, so that the riveting column 7 made of plastic material is softened by heat and is uniformly flattened under pressure, finally forming a limiting structure which can tightly cooperate with the limiting flange 72, so as to fixedly install the tray 2 in the accommodating cavity 11.

[0050] When the supporting plate 2 is installed into the accommodating cavity 11, the circumferential outer wall of the supporting plate 2 is in contact with the circumferential inner wall of the accommodating cavity 11. This design increases the stability of the supporting plate 2 in the accommodating cavity 11, and can prevent the supporting plate 2 from shaking or moving, and can also prevent dust, water vapor and the like from entering the installation space.

[0051] As shown in Figure 4 The bottom outer side of the clamping block 4 is formed with a transition surface 42, and the top of the supporting plate 2 or the position of the top of the supporting plate 2 opposite to the clamping block 4 is formed with an arc-shaped transition surface 22. The cooperation of the transition surface 42 and the arc-shaped transition surface 22 improves the smoothness during installation and reduces the frictional resistance during installation.

[0052] The inner top wall of the protective cover 1 is provided with at least two limiting columns 13, and the position of the supporting plate 2 opposite to the limiting columns 13 is provided with limiting through holes 23 capable of being matched and inserted with the limiting columns 13. Embodiment 2

[0053] The embodiment provides a shaving head, as shown in Figure 5 The protective cover is the protective cover in the embodiment 1. After the protective cover is installed on the mounting seat 5, the position of the magnetic member 3 is just opposite to the position of the blade 6, so that the protective cover is adsorbed and fixed on the mounting seat 5.

[0054] The two short inner walls of the protective cover 1 are respectively provided with friction surfaces 14, and the outer wall of the mounting seat 5 opposite to the friction surfaces 14 is provided with a plurality of convex strips 51, and the convex strips 51 are in extrusion contact connection with the friction surfaces 14. The extrusion contact connection of the friction surfaces 14 and the convex strips 51 enhances the friction between the protective cover 1 and the mounting seat 5, so that the protective cover 1 can be more stably attached to the mounting seat 5 in the closed state.

[0055] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the embodiments. For those skilled in the art, on the basis of the above description, other different forms of changes or variations can also be made. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the technical scheme.
