Description

Electric shaver

[technical field]

The present invention relates to a kind of razor device, particularly a kind of razor device of eccentric rotation.

[background technology]

Electric shaver can be divided into two kinds of rotary, nethike embrane formulas by its work characteristics, all is must the cutter development by the single head of the seventies.Wherein rotary is representative with the Philishave, and the cutter head processing mode of this type of electric shaver is quite complicated, and some also has the multilayer blade, its difficulty of processing is bigger, and material requirements is strict, the machining accuracy height, and durable inadequately, cutter head usually needs to change, thereby its cost is higher; The effect that shaves of this type of electric shaver neither be fine, and the plucking phenomenon is usually arranged, and that is to say to can't cut beard, causes people's pain.The residual beard in back that shaves of this type of electric shaver is also longer, so shave sordid sensation, when some beard looks long, this type of electric shaver just can't cut off beard again, so, this type of electric shaver often needs to add the temples cutter of a similar hair scissors, so that shave off long beard.

The nethike embrane formula is representative with German lark and PANASONIC.Adopt reciprocating type working method, it is big to scrape effective area recklessly, but noise is big and vibratory sensation is also strong excessively.Its shaver all passes through accurate how much and calculates, and is coated with platinum, and is more reliable in durability and security, but Just because of this, the also high material requirements of its cost is also high.This shaver has rechargeable and plug-in two kinds.The effect that shaves of this type of electric shaver neither be fine, and the plucking phenomenon is also usually arranged.The residual beard in back that shaves of this type of electric shaver is also longer, so shave sordid sensation, when some beard looks long, this type of electric shaver just can't cut off beard again, so, this type of electric shaver also often needs to add the temples cutter of a similar hair scissors, so that shave off long beard.

The shaver that also has a kind of drum-type recently, the similar hand slide rest shaver of its principle is formed a cylinder by some blades, drives its rotation to reach the purpose that shaves by motor.This shaver pain under dry situation is strong.This shaver machining accuracy is very high, and cost is also bigger.It is also not too convenient to use, and is not suitable for dry environment especially and is suitable for down, also can only change whole cylinder when change cutter head, is suitable for the cost height.

[summary of the invention]

The object of the present invention is to provide the revolving shaver of a kind of off-centre, overcome the various shortcomings of above-mentioned shaver.The better effects if that shaves of this shaver, can shave off easily general shaver shave less than beard, and need not to add in addition the temples cutter because moving knife rotatablely moves, its noise is also lower.Part processing of the present invention requires, material requirements is also simple thereby processing cost is lower, and the service life of part is also longer.Shaver of the present invention has outstanding cleanliness, comfort level, convenience and the outstanding cost performance of scraping.

Purpose of the present invention realizes by following means: a kind of razor device, and it has a fuselage, and one or more razors is installed on the fuselage, and fuselage interior is equipped with parts such as CD-ROM drive motor device, battery, switch.Moving knife, not moving knife, moving knife driver, moving knife spring, not moving knife set casing, base are arranged on the single razors.CD-ROM drive motor passes to power by the moving knife driver, because the installation moving knife position on the moving knife driver and the pivot of moving knife driver have certain deviation, therefore when the CD-ROM drive motor device drives the rotation of moving knife driver, moving knife driver drives moving knife rotation, at this moment moving knife will have relative displacement with moving knife not.This moment be in moving knife and not the beard between the moving knife will be cut off.Particularly,, cut off effect and follow when the rotation simultaneously of moving knife this moment, so, if moving knife with do not add a gear pair between moving knife set casing or the base, strengthen the moving knife rotation, strengthen the shearing of beard, the effect that shaves like this meeting is better.Because moving knife is eccentric rotation, area is bigger so it shaves, and long beard also shaves off easily.

The invention has the advantages that: 1) because moving knife is eccentric rotation, so its area that shaves is bigger than other shavers; 2) because moving knife oneself also has a rotation, so its noise also can be lower, and operation can be more steady.3) moving knife of this shaver is so strict not as other shavers with the processing request of moving knife not; 4) moving knife is directly faced the beard that will shave, and it is cleaner therefore to shave; 5) the moving knife thickness of this shaver is big, generally need not to change cutter head when therefore using.
