Abstract

An electric shaver comprises a body and a cutting tool bit comprising a round outer tool net cover and an inner tool holder. The utility model is characterized in that four raised work area ring surfaces with arc surfaces are arranged on the work surface of the round outer tool net cover; slight beard-in grooves and small round beard-in holes are formed on the four work area ring surfaces, thereby forming four raised outer blades with the arc surfaces; three connected rib round rings with concave faces and convex backs span the four raised outer blades with the arc surfaces; and a plurality of inner blades with edges matched with the arc surfaces are correspondingly arranged on the back surfaces of the four raised outer blades with the arc surfaces, thereby achieving better shaving effect in the states of coarse shaving, semi-fine shaving and fine shaving.

Description

Electric shaver

Technical field

The utility model relates to a kind of household electrical appliance, and particularly a kind of specializing in cut the electric shaver that beard is used.

Background technology

The electric shaver of the rotary cutting scheme of employing internal blade on sale is provided with one, two or three cutter tips usually on the existing market.Each cutter tip is provided with several blade with can form around the interior knife rest of round center rotation circle outside by one in the cutter guard by the outer cutter guard of fixed circle and one.On the working face of cutter guard, being provided with one or two is at most three raised type working region anchor rings outside each is circular.Between the inner and outer ring of whole raised type working region anchor ring, closely be provided with a large amount of outside radial elongate strip advance must groove and thin circle advance must the hole, by advance between each elongate strip must groove and thin circle advance must the hole between, the elongate strip arm of cross-over connection between the inner and outer ring of raised type working region anchor ring constitutes the outer blade of fixed raised type.A large amount of elongate strip is advanced and must be advanced and must closely link to each other on the anchor ring of working region with the outer blade of raised type in the hole with thin circle by groove, and constituting one or two is at most the circular outer cutter guard of three the outer blade of raised type.Outside this raised type on the back side of blade, corresponding be close to be movably set with several fixed installation be arranged at same rotatable in inner blade on the knife rest, during work, because the outer blade of circular outer cutter guard is convex shape, a little more than datum level on every side, therefore the skin that has a beard can be tight state when gently being affixed on the circular outer cutter guard, makes the beard root give prominence to, stretch into into palpus hole; Simultaneously, be provided with several interior knife rests and rotate with axle inner blade, inner blade outside circle outside the cutter guard inner close fitting back side of blade do break-in rotation and move, excising beard more nearby from fibrous root.Because the sharpness of shaver has obtained the approval in market, shave the time and reduce, improve the speed and the efficient that shave, become market to consider and requirement.Therefore, market has occurred circular outer cutter guard blade outside an initial raised type in succession and has been modified into two and its objective is and increase the working region of shaving still to being at most cutter guard outside blade three raised types outside circular, the raising efficient that shaves.Therefore, the speed that shaves of shaver and efficient directly influence the degree of recognition and the satisfaction in market.

The utility model content

Task of the present utility model is, effectively through the beard after the more coarse cutting, when passing through after the meticulous cutting again, the speed and the efficient that shave are increased, shave performance optimization and reduce a kind of novel razor device of the time of shaving thereby can reach.

The utility model is to realize like this, on the shaver basis of existing rotary cutting beard, under the prerequisite of shaver basic configuration that does not change existing one, two or three cutter tip and installation dimension, the outer cutter guard of circle is done structural improvement design.Circular outer cutter guard based on the outer blade of raised type, material thickness to the outer cutter guard of circle has been done corresponding adjustment, thereby increased the internal space of circular outer cutter guard, satisfy the circular outer cutter guard condition that the outer blade of four raised types can be set, increased the working region of beard cutting.On two regional anchor rings near the external annulus of cutter guard external diameter outside circular, be provided with a large amount of elongate strip radially respectively and advance the palpus groove, this is the working region for slightly shaving the beard, on two regional anchor rings near outer cutter net circle center internal ring wall, be provided with respectively elongate strip advance must groove with thin circle advance must the hole combine and a large amount of single thin circles advance must the hole, this is to be half smart shaving the beard and the meticulous working region that shaves the beard.The inherence amplification of considering the outer cutter guard cutting face of whole circle influences its intensity, four raised type working region anchor rings are designed to around the arc-shaped surface of the circular shaft mind-set face outer lug of circular outer cutter guard, the working region anchor ring that makes four raised types is all on arc-shaped surface, in cross-over connection between four raised type working region anchor rings, three protruding muscle annulus of face hollow back are set to join, this measure has increased the resistance to compression and the tensile strength of circular outer cutter guard, therefore be built into the outer blade that four raised types have arc-shaped surface, so their common combination has been achieved a circular outer cutter guard with new implication.In addition, four raised types have the outer blade of circular arc, and it can also make the skin of contact have under the pressure, and skin surface can produce relatively more consistent tight power on all directions, thereby have improved the cutting ability of beard.Several inner blades that the back side that has simultaneously the outer blade of circular arc at four raised types, corresponding inner blade blade and circular arc match, slightly shave cutting, partly essence is shaved under cutting, the meticulous state of shaving cutting, makes the cutting effect of beard better.

Based on above-mentioned design, electric shaver of the present utility model, comparing with existing similar razor, though the outer cutter guard parts of circle have been done structural improvement, promptly from originally being at most that the cutter guard is modified into cutter guard outside the circle that four raised types have blade outside the arc-shaped surface outside blade three raised types outside circular.But increased the working region of shaving, but do not influenced original basic global shape and installation dimension, structure is still very simple, and has increased thick, smart cutting zone.Shaving quality and reduced the time of shaving thereby improved greatly, thereby have tangible creativeness, practicality and economy, is a kind of desirable daily razors.
