[0034] refer to Figure 1-7The figure discloses an electric shaver 100, which includes a main body 10 and a cutter head arranged on the main body 10. The main body 10 includes a shell 4, which defines a storage space, and a brushless motor 5 and a battery pack 6 that provides power to the brushless motor 5 are arranged in the storage space. A frame 41 is installed in the shell 4, and the frame 41 is used to install the brushless motor 5 and the battery pack 6. The frame 41 includes a frame body and a cover body 42, and a mounting cavity for installing the transmission structure 3 is defined between part of the frame body and the cover body 42. A controller 7 is also installed on the frame 41. The controller 7 can be a PCB board, which is a conventional technology and will not be described in detail here. An adjuster is provided on the controller 7, and the gear and switch of the shaver can be adjusted by the adjuster. In order to enable the frame 41 to be stably installed in the shell 4, the frame 41 is mounted to the shell 4 by a plurality of fasteners, wherein at least one of the plurality of fasteners is located on a different surface of the shell 4 from the other fasteners. In one embodiment, multiple fasteners are provided on the front side of the shell 4, i.e., the side with the buttons, and one fastener is provided on the back side of the shell 4. In this way, the frame 41 can be stably fixed in the shell 4 from two different directions.

[0035] refer to Figure 1 and 2 The electric shaver 100 also includes a cutter head. The cutter head is detachably mounted on the upper end of the main body 10, and the cutter head includes a first cutter head 1 and a second cutter head 2 that are independent of each other. The first cutter head 1 includes a first shell 11 and a first blade assembly 12 disposed in the first shell 11. The first blade assembly 12 is connected to the brushless motor 5 through a transmission structure 3. The second cutter head 2 includes a second shell 21 and a second blade assembly 22 disposed in the second shell 21. The second blade assembly 22 is connected to the brushless motor 5 through a transmission structure 3. The first cutter head 1 and the second cutter head 2 can be removed from the main body 10 separately. With the above structure, any one of the cutter heads can be replaced, effectively reducing the replacement cost.

[0036] refer to Figure 3 and 4 The transmission structure 3 includes a driving gear 31 mounted on the output shaft of the brushless motor 5, and a first transmission gear 32 and a second transmission gear 33 meshing with the driving gear 31. The first transmission gear 32 is mounted with a first transmission shaft 34, and the second transmission gear 33 is mounted with a second transmission shaft 35. The first transmission shaft 34 drives the first cutting head 1. The second transmission shaft 35 drives the second cutting head 1. This structure enables high-speed rotation of the blades. Because the motor is a brushless motor 5, the blade net rotates faster, resulting in a better shaving effect.

[0037] To facilitate the installation of the cutting heads on the main body 10, a first mounting bracket 36 and a second mounting bracket 39 are provided on the main body 10. The first cutting head 1 is detachably mounted on the first mounting bracket 36 by magnetic attraction, and the second cutting head 2 is detachably mounted on the second mounting bracket 39 by magnetic attraction. The magnetic mounting method is more convenient. Of course, other mounting methods can also be used.

[0038] To enhance the sealing performance of the entire main body 10, a first sealing structure 37 is provided between the first mounting bracket 36 and the housing 4. The first sealing structure 37 defines a first hole for the first transmission shaft 34 to pass through. A second sealing structure 301 is provided between the second mounting bracket 39 and the housing 4. The second sealing structure 301 defines a second hole for the second transmission shaft 35 to pass through. This sealing structure effectively prevents liquids from entering the interior of the main body 10. This makes the electric shaver 100 washable, making cleaning more convenient.

[0039] refer to Figure 5-7 In a specific embodiment, the first blade assembly 12 includes a first cutting net 13, a first blade 14, and a first elastic support 15. The first blade 14 is disposed between the first cutting net 13 and the first elastic support 15. The second blade assembly 22 includes a second cutting net 23, a second blade 24, and a second elastic support 25. The second blade 24 is disposed between the second cutting net 23 and the second elastic support 25. To ensure that the cutting nets better conform to the skin, the first elastic support 15 includes a first support portion 16 and a plurality of first elastic portions 17 disposed around the periphery of the first support portion 16; the plurality of first elastic portions 17 are used to support the first cutting net 13. The second elastic support 25 includes a second support portion 26 and a plurality of second elastic portions disposed around the periphery of the second support portion 26; the plurality of second elastic portions 27 are used to support the second cutting net 23. When the cutting net is subjected to external force and squeezed by the skin, the first elastic portion 17 can deform, and portions of the cutting net can shift to better conform to the skin.

[0040] The first support portion 16 defines a first through-hole 38, which is surrounded by a plurality of magnets that allow the first cutting head 1 to be mounted to the main body 10. A first transmission shaft 34 passes through the first through-hole 38 and is in transmission connection with the first blade net 13. The second support portion 26 defines a second through-hole 302, which is surrounded by a plurality of magnets that allow the second cutting head 2 to be mounted to the main body 10. A second transmission shaft 35 passes through the second through-hole 302 and is in transmission connection with the second blade net 23.

[0041] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
