The mirror assembly 2 is detachably connected to the housing 1 via the connecting assemblies 3. The connecting assembly 3 includes mutually matching sub-connecting assemblies 31 and female connecting assemblies 32. The sub-connecting assembly 31 is disposed on the mirror assembly 2, and the female connecting assembly 32 is disposed on the housing 1. In this embodiment, the detachable connection between the mirror assembly and the housing is achieved through the cooperation of the sub-connecting assembly and the female connecting assembly. The user can replace the plane mirror or a concave mirror of different magnifications according to usage requirements. Of course, it is not limited to this; any other method that allows for easy disassembly and installation of the mirror assembly can be used.

[0047] Specifically, such as Figure 4 As shown, the sub-connecting assembly 31 includes a snap-fit ​​portion 311, and the female connecting assembly 32 includes a connecting groove 321. In this embodiment, a snap-fit ​​limiting portion 322 for limiting the snap-fit ​​portion 311 is provided on the connecting groove 321, and the snap-fit ​​limiting portion 322 and the snap-fit ​​portion 311 are matched with each other. In this embodiment, when installing the mirror assembly, first align the snap-fit ​​portion with the connecting groove, and then rotate the snap-fit ​​portion into the position of the snap-fit ​​limiting portion, thereby realizing the installation of the mirror assembly; when it is necessary to replace or disassemble the mirror assembly, rotate the mirror assembly in the opposite direction to move the snap-fit ​​portion away from the snap-fit ​​limiting portion, thereby realizing the disassembly of the mirror assembly.

In this embodiment, the light-emitting assembly is an LED light, and the power supply assembly is a battery. By providing the light-emitting assembly and the power supply assembly, illumination can be provided when the mirror is used. Of course, it is not limited to this; any other light-emitting assembly capable of providing illumination can be used.

[0051] The housing 1 is provided with a power interface 13 and a switch assembly 14. The power interface 13 is connected to the power assembly 11, and the switch assembly 14 is connected to the light-emitting component 12. The power interface 13 charges the power assembly 11 by connecting to an external power source, and the switch assembly 14 controls the light-emitting component 12 to turn on and off. In this embodiment, the switch assembly is used by the user to control the opening and closing of the light-emitting component or to switch the light-emitting mode; the power interface is used to connect to an external power source to charge the power assembly or to directly power the light-emitting component.

[0053] Example 2

[0054] The basic structural settings of Embodiment 1 and Embodiment 2 are the same, the main difference is:

[0055] Specifically, such as Figure 5 As shown, the sub-connecting component 31 is a hook-and-loop fastener component, and the female connecting component 32 is a textured surface component; alternatively, the sub-connecting component 31 is a textured surface component, and the female connecting component 32 is a hook-and-loop fastener component; or both the sub-connecting component 31 and the female connecting component 32 are hook-and-loop fastener components. In this embodiment, the sub-connecting component is a hook-and-loop fastener component, and the female connecting component is a textured surface component, and both the sub-connecting component and the female connecting component are hook-and-loop fastener components; or both the sub-connecting component and the female connecting component are hook-and-loop fastener components. The sub-connecting component and the female connecting component form a Velcro assembly, and the sub-connecting component and the female connecting component are connected to each other through textured surface components and hook-and-loop fastener components, or through two hook-and-loop fastener components, making the mirror assembly easy to disassemble or replace. Of course, it is not limited to this; any other fastener that makes the mirror assembly easy to disassemble or replace can be used.

[0056] Example 3

[0057] The basic structural settings of Embodiment 1 and Embodiment 3 are the same, the main difference is:

[0058] Specifically, such as Figure 6 , 7 As shown, the sub-connecting component 31 is made of a magnetic material, and the female connecting component 32 is made of a metal material that can be attracted by a magnetic material; alternatively, the sub-connecting component 31 is made of a metal material that can be attracted by a magnetic material, and the female connecting component 32 is a magnetic material; or both the sub-connecting component 31 and the female connecting component 32 are made of magnetic materials. In this embodiment, the sub-connecting component is made of a magnetic material, and the female connecting component is made of a metal material that can be attracted by a magnetic material; alternatively, the sub-connecting component is made of a metal material that can be attracted by a magnetic material, and the female connecting component is a magnetic material; or both the sub-connecting component and the female connecting component are made of magnetic materials. The sub-connecting component and the female connecting component form a magnetic adsorption component. The sub-connecting component and the female connecting component attract each other to achieve the installation of the mirror component. When the external force is greater than the adsorption force of the sub-connecting component and the female connecting component, the mirror component can be disassembled. Of course, it is not limited to this; other materials that facilitate the disassembly or replacement of the mirror component can be used.

[0059] Example 4

[0060] The basic structural settings of Embodiment 1 and Embodiment 4 are the same, the main difference is:

[0061] Specifically, such as Figure 8 , 9As shown, the sub-connecting assembly 31 includes a cylindrical ball-head snap-fit ​​member 312, and the female connecting assembly 32 includes an elastic element 323 and an elastic limiting member 324, with the elastic limiting member 324 disposed on the elastic element 323. In this embodiment, the end of the cylindrical ball-head snap-fit ​​member is spherical, the elastic element is a spring, and the elastic limiting member is an elastic buckle. When installed, pressing the cylindrical ball-head snap-fit ​​member allows the ball-head shape and the elastic force of the elastic limiting member to snap the cylindrical ball-head snap-fit ​​member into the elastic limiting member and abut against the elastic element. The elastic limiting member resets due to its elasticity, limiting and snapping the cylindrical ball-head snap-fit ​​member, thus completing the installation of the mirror assembly. When disassembling, pressing the cylindrical ball-head snap-fit ​​member again causes it to open the elastic limiting member and squeeze the elastic element. The elastic force of the elastic element ejects the cylindrical ball-head snap-fit ​​member, thus completing the disassembly of the mirror assembly. However, it is not limited to this; it can be any other component that makes the mirror assembly easy to disassemble or replace.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
