[0044] Example 2

[0045] On the basis of embodiment 1, the first end surface 54 and / or the second end surface 55 of the protective cover 5 are provided with a magnet 12. Figure 1 The protective cover 5 is provided with a magnet 12 on the first end face 54 or the second end face 55, that is, the magnet 12 is provided on one of the end faces of the protective cover. This design requires the user to align the end face provided with the magnet 12 with the end face of the bottom of the inner shell 3 close to the Hall switch 10. If it is installed upside down, the Hall switch 10 cannot be activated, that is, the power tool cannot be started; another solution is that the protective cover 5 is provided with magnets 12 on both the first end face 54 and the second end face 55, that is, the front and rear end faces of the protective cover are provided with magnets 12. With this design, even if the user installs the protective cover upside down on the bottom of the inner shell 3, the user can approach and activate the Hall switch 10, that is, start the power tool. This design allows the patient to not consider whether the protective cover 5 is installed upside down, making the protective cover 5 non-directional. As long as it is installed at the bottom of the inner shell 3, the power tool can be successfully started.

As long as the inner shell and the outer shell can achieve relative sliding, it falls within the protection scope of this embodiment.

[0055] As a preferred embodiment, see Figure 4 and Figure 5 The top and bottom of the housing 4 are respectively provided with a first groove 42 and a second groove 43, and the bottom of the protective cover 5 is provided with a first protrusion 53, the first protrusion 53 is provided in cooperation with the first groove 42, and the first protrusion 53 is provided in cooperation with the second groove 43; specifically, see Figure 4 and Figure 5In order to make the fit between the protective cover 5 and the outer shell 4 tighter and more precise, when the protective cover 5 is installed on the outside of the working assembly 2, the first protrusion 53 is matched with the first groove 42; when the protective cover 5 is installed on the outside of the bottom of the inner shell 3, the first protrusion 53 is matched with the second groove 43; see Figure 6 , Figure 6 It is a three-dimensional view of the protective cover 5 on the top of the shell 4. The protective cover 5 and the shell 4 are precisely matched and have an exquisite appearance.

[0056] Example 7

[0057] See also Figures 11 to 13 , this embodiment discloses a specific implementation of a personal care power tool.

[0058] Personal Care Power Tools, see Figures 11 to 13 , including a driving component 1, a working component 2, a shell 13 and a protective cover 5. The driving component 1 and the working component 2 are arranged inside the shell 13, and the protective cover 5 is arranged on the outside of the working component 2. The driving component 1 is provided with a Hall switch 10, and the protective cover 5 serves as a switch of the working component 2 when moving.

[0059] Specifically, under normal circumstances, the main function of the protective cover 5 is to protect the working component 2, and the protective cover 5 does not have any other functional functions; in this embodiment, the protective cover 5 will become an indispensable part of the personal care power tool. Specifically, the protective cover 5 serves as a switch for the working component 2 when moving.

[0060] For example, see Figure 11 A magnet 12 is provided on the protective cover 5, and the Hall switch 10 is electrically connected to the driving component 1 and is positioned close to the magnet 12. When the protective cover 5 is removed, that is, when the protective cover 5 drives the magnet 12 to move relative to the Hall switch 10, the Hall switch 10 is activated, thereby starting the working component 2; when use is completed, the protective cover 5 is installed on the outside of the working component 2. When the protective cover 5 drives the magnet 12 to approach the Hall switch 10, the Hall switch 10 is turned off, thereby turning off the working component 2.

[0061] For example, see Figure 12 , a magnet 12 is set on the protective cover 5, and the Hall switch 10 is electrically connected to the drive component 1 and is located close to the bottom of the drive component 1. When the protective cover 5 is removed and the Figure 13When the protective cover 5 is installed at the bottom of the housing 13 in a manner, that is, when the protective cover 5 drives the magnet 12 to approach the Hall switch 10, the Hall switch 10 is activated, and thus the working component 2 is activated; when use is finished, the protective cover 5 is removed from the bottom of the housing 13. The removal process is the process when the protective cover 5 drives the magnet 12 away from the Hall switch 10. At this time, the Hall switch 10 is turned off, and then the working component 2 is turned off. After closing, the protective cover 5 is put back to its original position, that is, the outside of the working component 2.

[0062] This embodiment enables the protective cover 5 of the power tool to have the function of a switch, that is, the protective cover 5 becomes a functional and indispensable part of opening or closing the power tool, thereby preventing the user from placing the protective cover 5 at will and avoiding the possibility of losing the protective cover 5.
