[specific embodiment]
It elaborates with reference to the accompanying drawing to embodiments of the present invention.
As shown in Figures 1 to 6, the blade of one of the present embodiment rotary electric shaver, including knife in a ring
Disk 1 and the attachment base 2 for being fixedly connected on 1 middle part of cutterhead, the upper surface of the cutterhead 1 is equipped with multiple cutter hubs 11, each described
Cutterhead 1 end be equipped with cutting face 111, the cutting face 111 is formed with cutting edge 112, the knife in 11 tip of cutter hub
Body 11 and cutterhead 1 use ceramic material integrated injection molding, and the attachment base 2 is using plastic injection at 1 middle part of cutterhead.This hair
Bright attachment base 2 is directly injection-moulded in 1 middle part of cutterhead using plastics, and the attachment base 2 and cutterhead 1 made connects even closer, to knife
When piece carries out drop test, because of the good integrity of cutterhead 1 and attachment base 2, without internal stress, therefore cutterhead 2 will not be cracked
