Description

Annular razor-blade

The present invention relates to a kind of improved razor blade, particularly a kind of edge of a knife that shaves is completely enclosed within inboard safety blade.Existing shaver and razor blade, the edge of a knife are all in the outside, and owing to be linear, people in use slightly pull evil to people's skin easily.

Task of the present invention provides a kind of follow-on razor blade, and it can change edge of a knife injury to people's skin in the outside, and the shave advantage of clean safety of a kind of blade before possessing simultaneously.

Task of the present invention is finished in such a way.On original blade shapes of producing, improve and then can, it is constant that raw material and thickness are all pressed prior blade, make a garden endoporus with the same garden of outer shape shape at the stalloy center of a garden shape, and on the edge in Nei Yuan hole, made the edge of a knife just, in order to prevent in use, garden shape blade rotates in the frame that shaves, can be at all or part of rubber of coating in the outside of garden shape razor blade.Finish like this with the knife rest that blade is used, at the bottom of an end of the garden of metal tube has a hollow garden littler than garden tube to hold up garden shape blade, make the gradient to declivity of a garden annular at the backing of tube inboard, garden, its angle fixes between 2 °-4 °, put into behind the blade again by one and be torqued into stopper by what outer surface thread was formed, the last end of stopper (it is inner to enter tube) is also made the inclination garden platform of a garden annular in advance, and its smooth surface, and the groove that inwardly has several half garden shapes.Because blade, the stopper roof pressure make the little oblique angle of 2 °-4 ° of its edge of a knife generations to turning up.Rely on the blade that slightly turns up out to scrape off beard etc. when shaving.2/3 remaining blade is in level and smooth kind of skin and deviates from state, and then left and right two semi-rings that link to each other with use face are in plain grinding, is using the relative ring of face to be in and is deviating from state, and what injury skin is not had.What produce when shaving must must discharge by the hole that the garden tube is held successfully by groove by row by foam again.The structure of row's palpus groove is that distribution 3-4 (or a plurality of) dig the into half garden shape cell body on inclined-plane on the roof pressure blade face slope of stopper, and palpus foam etc. is discharged the outside by the hole of driveing on the tube of garden thus.

This razors, because the number of degrees that the knife face edge of a knife contacts with skin seldom, and the characteristics of garden shape have been avoided a linear pattern blade pulling skin, blade is taken out and is put into and needn't worry the incised wound finger, and also there are forms such as hook, saw in the knife face that shaves except having the effect of scraping, significantly reduced the resistance that the edge of a knife shaves, using both totally, can improve the service life and the number of times of blade again, is a kind of desirable Shaving tool.
