Description

Interleaved multi-layer trimming head for electric hair clippers

technical field

The invention relates to the field of hair cutting equipment, in particular to a staggered multi-layer trimming head applied to electric hair clippers, which has an adjustable movable blade design, which can be adjusted to a single cutting track or multiple cutting tracks. Quickly complete various hair cutting effects without changing the original operating habits.

Background technique

Generally, hair stylists will use special hair cutting tools to cut hair for customers. These special hair cutting tools generally include special scissors and electric hair clippers. Different hair cutting tools are used for trimming according to the needs of hair stylists and customers.

However, the scissors for haircuts are designed to be sharp in order to achieve a neat and trimmed effect. Therefore, special attention should be paid to the safety of use and storage. The electric hair clipper uses an electric motor combined with cross-operating blades to quickly cut hair. It is mainly used for trimming a large amount of hair, such as: when cutting a flat head, due to the fast cutting speed, it is usually impossible to accurately control when dealing with details. Some hair stylists use a combination of both when cutting hair. However, when the above two haircutting tools are used, the hair stylist will cut the hair by grasping by hand or combing the desired amount of hair with a comb. The blades of these scissors and electric hair clippers are made of The side-to-side cutting method uses the method of extruding and cutting the hair in one direction. Not only does the incision form an inclined plane and is not flat, but also when layered hair is cut, it is usually necessary to spend more time using special haircuts for layered haircuts. Scissors.

Taking an electric hair clipper as an example, it has a main body, and a motor and a power source are arranged inside the main body, and a trimming head is installed at the front end of the main body. It can form a cutting track. Therefore, the cutting track formed by the trimming head is used to cut the hair during the operation. Because the cutting speed of the electric hair clipper is extremely fast, it is mostly used for clippers. That is to say, a large area of hair is cut. When operating, the trimming head is usually equipped with a baffle with a controlled length, one side of which is used to abut the scalp, and the gap formed between the baffle and the trimming head is used. distance, while quickly adjusting its trim length. The reason is that this kind of electric hair clipper can only perform large-area hair trimming. When it is necessary to cut hair with distinct layers, it is still necessary to manually operate special scissors for layer trimming. When cutting, it produces different levels of effects, and it is impossible to quickly trim and control the length of the trim level, so it is necessary to improve it.

Therefore, the present invention has accumulated many years of practical experience in designing hair cutting tools, and developed a staggered multi-layer trimming head structure that can be applied to electric hair clippers. The adjustable movable blade design can be adjusted to a single trim during cutting. Cutting track or multi-splicing track can quickly complete various hair cutting effects without changing the original operating habits.
