Electric shaver: The electric shaver is composed of stainless steel mesh cover, inner blade, micro motor and shell. The net cover is a fixed external blade with many holes on it, and the beard can stretch into the holes. The micro motor is driven by electric energy to drive the inner blade to act. The beard that extends into the hole is cut off by using the shearing principle. The electric shaver can be divided into rotary type and reciprocating type according to the action characteristics of the inner blade. The power supply includes dry battery, storage battery and AC charging.
Electric shavers are generally divided into two types:
1. Rotary type
The rotary shaver is not easy to hurt the skin and cause bleeding, so friends with sensitive skin can focus on it! In addition, it is quiet to operate and has a gentlemanly manner.
Relatively speaking, the rotary operation is quiet and has the feeling of a gentleman shaving. It is better to use rotary type for people with skin allergy. It does little harm to the skin and generally does not cause bleeding. Most of the rotary shavers on the market have a power of 1.2W, which is suitable for most men. But for men with thick and dense beards, it is better to use shavers with higher power, such as the newly developed 2.4V and 3.6V three head rotary series. Under the super power, no matter how thick your beard is, it can be shaved in an instant. From the perspective of hygiene, it is better to use waterproof series, whose flushing function can effectively inhibit the formation of bacteria.
2. Reciprocating
The principle of this kind of shaver is simple. It looks like a knife used by a barber when shaving, so it is very sharp and suitable for short and thick beard. However, because the blade often moves back and forth, the loss is often fast. The utility model has the advantages of higher shaving cleanliness and larger shaving area. The motor speed is high, which can provide powerful power. The fast rotating motor drives the left and right swinging blades to clean the beard easily and quickly, and the left and right swinging blades will never drag the beard.
Maintenance of electric shaver:
Because most of the built-in rechargeable batteries of rechargeable shavers have memory effect, they should be fully charged and discharged each time. If it is not used for a long time, the residual power should be discharged completely (start the machine and idle until the knife no longer rotates), and stored in a dry place. In order to maintain the best shaving effect for the blade of the shaver, the blade net should be well protected to avoid collision. If the blade is not cleaned for a long time, which causes unclean shaving, the blade should be opened for cleaning (a larger brush can be used). If there is blockage, the blade can be soaked in water containing detergent for cleaning.
Tool head type
The most important factor for electric shaver to clean beard is the blade. Proper blade design can make shaving a pleasure.
The shaver heads sold on the market can be roughly divided into turbine type, staggered type and omentum type.
1. Turbine cutter head: use the rotating multilayer blade to shave off the beard. This cutter head design is the most commonly used razor.
2. Staggered knife head: use the principle of staggered vibration of two metal blades to push the beard into the groove for scraping.
3. Reticulum type cutter head: use dense omentum design to generate rapid vibration and reduce
Scrape off the beard residue.
Number of bits
Whether the blade is sharp directly affects the shaving efficiency. In addition, the number of cutter heads is also a decisive factor.
In the early days, the blade of electric shaver was designed with a single blade, which could not completely shave the beard. With the progress of technical design, better shaving effect can be obtained.
The electric shaver with double heads has always had a fairly good shaving effect, but it is not easy to remove the small beard or the curve angle of the chin. In order to solve this problem, the new product has added the design of “the fifth knife”, that is, three knife heads are added around two knife heads. When the two knife heads are immersed in the skin, the other five knife heads completely scrape off the residue that cannot be scraped. At the same time, it conforms to the ergonomic design and can completely remove the dead corners of the chin.
function
In terms of functions, in addition to the basic shaving function, the electric shaver also has the functions of “blade cleaning display”, “power storage display”, etc. In addition, the new generation of electric shaver has also successfully developed a multi kinetic combination, including sideburns knife, hairdresser, facial brush and nose hair device
In addition, some brands specially design youth electric shavers for young people from 19 to 25 years old, emphasizing the youthful flavor. It gets rid of the impression that the electric shaver is a mature and stable product for men, so as to expand the consumer group of electric shaver.
A. The first thing to see is whether the blade is smooth and whether the hood is pitted
B. Check whether the motor operates normally and whether there is noise
C. Finally, check whether the shaver is clean and comfortable
D. Select brand products with guaranteed quality
There are many kinds of electric shavers, and their rated voltage, rated power, transmission mechanism, structural principle and price are quite different. When purchasing, we should adjust measures to local conditions, according to each person’s economic situation and specific requirements, and refer to the following points:
1. If there is no AC power supply or the user often goes out to carry, the electric shaver driven by dry battery is generally preferred.
2. If there is an AC power supply and it is often used in a fixed place, it is better to choose an AC power supply or rechargeable electric shaver.
3. If you want to adapt to various occasions, you should choose an AC, rechargeable, dry battery type multipurpose electric shaver.
4. If the beard is sparse, thin, and the skin is smooth and requires shorter shaving, the vibrating reciprocating electric shaver or the general rotary electric shaver can be selected. For beards with thick and hard mustaches, you can choose rectangular slit type electric shaver, circular slit type electric shaver, or three head or five head rotary electric shaver. However, this kind of electric shaver is complex in structure and expensive.
5. Cylindrical sealed nickel copper battery is preferred as the battery used for rechargeable electric shaver, which requires convenient charging, safety, reliability and long service life. Alkali manganese battery or manganese dry battery is better for dry battery used in electric shaver of dry battery type, and it requires convenient battery replacement, good contact and long service life.
6. During use, there should be no obvious vibration, and the action should be quick.
7. Beautiful and light shape, complete parts, good assembly, convenient and reliable assembly and disassembly of accessories.
8. The blade of the electric shaver should be sharp, and its sharpness is generally judged by people’s feelings. It is mainly painless to the skin, safe to cut, and free of hair pulling stimulation. The residual hair after shaving is short, and there is no obvious feeling when wiping with hands. The external knife can slide smoothly on the skin.
9. It is easy to clean after use. Hair and beard: dander should not easily enter the electric shaver.
10. It shall be equipped with a housing for storing and protecting the blade, or with a structure for retracting the blade or the whole blade.
11. The insulation performance is good, safe and reliable, without any leakage.
12. The noise of no-load operation of electric shaver shall be small, uniform and stable, and there shall be no noise of light and heavy fluctuations.
