(1) Type of cutter head
Whether an electric razor can shave clean beard, the most important factor is the blade. Properly designed cutter heads can make shaving beard a pleasure.
The heads of razors on the market can be roughly divided into three types: turbo type, cross-cut type and omentum type.
1. Turbine head: Uses rotating multi-layer blades to shave off the beard. This head design is the most commonly used razor.
2. Staggered knife head: Using the principle of staggered vibration of two metal blades, the beard is pushed into the groove and shaved off.
3. Omentum-type cutter head: Utilize the dense omentum design to produce rapid vibration and scrape off small scum.
(2) Number of cutter heads
Whether the cutter head is sharp or not directly affects the efficiency of shaving. In addition, the number of cutter heads is also a decisive factor.
The blade of the early electric shaver was designed with a single blade, which could not completely shave the beard. With the advancement of technical design, to obtain better shaving results.
The double-head electric shaver has always had a good shaving effect, but it is not easy to shave off the small beard or the curved angle of the chin. In order to solve this problem, the new product has added a "third knife" design, that is, a third knife head is added between the two knife heads. When the double knife head sinks into the skin, the third knife head will not be able to scrape. The scum is thoroughly scraped off. At the same time, the "third knife" conforms to the ergonomic design, which can completely remove the dead corners of the chin and beard.
(3) Function
In terms of functions, in addition to basic shaving functions, the electric shaver also has additional functions such as "blade head cleaning display" and "storage power display". In addition, the new generation of electric shavers have also developed a "sideburn knife" that successfully shaves men's hair, so that men can always keep their sideburns neat.
In addition, some brands specifically design youthful electric shavers for young people between the ages of 19 and 25, emphasizing youthfulness. It gets rid of the previous impression that the electric shaver is a mature and stable product for men, so as to expand the consumer group of electric shavers.
