Technical Field
[0001] The utility model relates to the technical field of shavers, in particular to a floating and fixed structure of a shaver. Background Technique
[0002] An electric shaver consists of a stainless steel mesh cover, an inner blade, a micro motor and a housing. The mesh cover is the fixed outer blade with many holes through which the beard can extend. The micro motor is driven by electric energy to drive the inner blade to act. Using the shearing principle, the beard extending into the holes is cut off. Electric shavers can be divided into two types, rotary and reciprocating, according to the action characteristics of the inner blade. The power sources used include dry batteries, storage batteries and AC charging, etc. At present, the structural mode of most knife head seats on the market is as follows: there is a knife head seat with three mounting holes on it. There is a triangular reinforcing rib with a square hole in the middle of the three forks of the knife head seat. Three knife grid frames are arranged on the mounting holes, and the knife net is placed inside the knife grid frames. A support frame assembly composed of a plastic card with three plastic cards and elastic pieces and a knob with an undercut is combined to form a knife head seat. The up and down floating of the knife net is achieved by the plastic card compressing the six-claw elastic piece to move up and down and is fixed or loosened by the knob. In the prior art, the disadvantages of this structural mode are that there are many parts, the structure is complex, the assembly working hours are long, and the cost is high.
