Description

Rotary electric shaver

The invention belongs to a kind of rotary electric shaver

Rotary electric shaver net cover structure on the existing market mainly contains two kinds, it is a kind of that to be guard be staggered to form fine and closely woven mesh by net bar circumferentially and radially, this net cover structure makes it effective to shaving the hair that removes weak point, and long hair can be difficult to stretch into mesh and shaves and remove because of the obstruct of net bar, so also made up little clipper, remove long hair so that shave earlier, use inconvenient.Also having a kind of is that guard has only radially net bar, and there is not circumferential net bar, thereby form the strip mesh, this strip mesh makes long hair ratio be easier to stretch into, but it is thinner because the thickness of guard needs, this formula construction machine intensity is bad, so its area that shaves can not be done very greatly, thereby has made up two covers even three guard and the blades that overlap.China Patent No. 92239441 disclosed " compound mesh formula electric shaver guard " is characterized in that guard has two kinds of meshes, a kind of is fine and closely woven mesh, another kind is that the stupefied limit that is the strong projection of corrugation from inside to outside constitutes the elongated shape mesh, shaves and feels bad though this elongated shape mesh makes long hair be easier to stretch into air spots.

The object of the invention provides a kind of rotary electric shaver, and the net cover structure that mainly solves in the past can not be shaved the hair that removes length, maybe can shave and remove long hair and the little problem of the area that shaves.

The present invention provides electric power by power supply to motor, and the motor drives knife rest is done the circumference rotation.The guard middle part recessed or the periphery spring pull down, or recessed while neighboring, guard middle part is also curved pulls down, the elongated shape mesh is extended down to the guard side from guard is positive through curved tearing open, guard neighboring or inner rim just form broach shape structure, distributing between week and the periphery in the guard circumferentially the net bar and radially the net bar be staggered to form fine and closely woven mesh, the blade on the knife rest is close to guard and is done circumference and rotate.As long as guard neighboring or inner rim have this broach shape structure, long hair just is easy to stretch into guard neighboring or inner rim broach shape structure mesh and is shaved by blade and remove, and this broach shape structure is removed long hair than easier the shaving of strip eyed structure.Be staggered to form fine and closely woven mesh by net bar circumferentially and radially in the middle of the guard and between the periphery, remove short hair in order to shave, fine and closely woven mesh can be that little strip also can be the roundlet hole.

This shaver is circumferentially having three groups or three groups with cutter, every group of blade formed radially being staggered by blade narrower more than two or two, little spring effect is separately arranged between each blade and the knife rest, blade is close on the guard separately, and the periphery of guard, middle part and interior Zhou Douneng closely contact with blade well like this.The very fast available three groups of blades of knife rest rotation, rotation slow available three groups with cutter to accelerate the speed that shaves.The big every group of blade of guard area can form radially being staggered with blade narrower more than two, and guard area I is with two blades.The guard that the rotary electric shaver area is bigger was a dome shape in the past, such guard pressurized is not easy distortion, adopt the structure that radially contacts guard by single wide blade, but contacting the most closely according to the custom that shaves with skin surface, the position is the center of guard, and the guard center there is no the function that shaves, also can shave the hair that removes length if this structure guard neighboring or inner rim have broach shape structure, but can not finely utilize whole guard area.Interior all positions that the present invention has utilized periphery position or central fovea to go down and form, for the positive periphery of whole guard position is contacted with skin better with interior all positions, the guard front is plane, and plane guard easily contacts the surface of more kinds of shapes than the easy pressurized slight deformation of dome shape guard.If but adopt the structure that radially contacts guard in the past by single wide blade, blade can not contact with interior week with the periphery of guard well simultaneously, so adopt by blade narrower more than two or two and form the structure of one group of blade radially being staggered, even guard pressurized slight deformation periphery, middle part closely contact with blade well with interior Zhou Douneng.

At knife rest excircle position or the blade at inner periphery position be tilt to install, blade is close in front and side that the front and the side surface direction of guard all is provided with blade and guard.Because the guard periphery is a broach shape structure, long hair stretches into from the guard front, stretches out from the guard side again, and blade can excise long hair with positive just contact of guard.But also have the hair between guard front and the guard side to stay in the guard.If the very long meeting of the hair outside the guard side is wrapped in the rotation that influences blade on the blade.So also be provided with blade in the guard side.Blade can excise the hair of the length outside the side simultaneously like this, prevents that wrapping phenomena from taking place.

Guard of the present invention is staggered to form fine and closely woven mesh by net bar circumferentially and radially, area is big so the good guard of mechanical strength shaves, the elongated shape mesh is extended down to the guard side from guard is positive through curved tearing open, guard neighboring or inner rim form broach shape structure, and long hair is easy to stretch into shaved by blade and removes.

The invention will be further described below with reference to accompanying drawing:

Fig. 1 is that schematic diagram is launched in the front of guard

Fig. 2 is the front schematic view of knife rest and blade

Fig. 3 is a side schematic view of the present invention

With reference to Fig. 1, guard front (6) has longilineal mesh (2), guard front (6) with handing-over position, guard side (7) longilineal mesh (4) to be arranged with handing-over position, guard side (5), and mesh (2) and mesh (4) are extended down to the guard side from the guard front.Mesh (2), mesh (4) can be split into long 3mm, the bar shaped of wide 0.3mm.Circumferentially net bar and net bar radially are staggered to form fine and closely woven mesh (3) and are used to shave and remove short hair, can be split into the bar shaped of long 1mm, wide 0.3mm, also can be split into the small circular of diameter 0.4mm.The mesh of 1/4th sectors that only draws among Fig. 1, the bar shaped direction of mesh (2), mesh (3), mesh (4) should with radially tilt a little, prevent that blade is stuck on the mesh to make the blade rotation more smooth.Dotted line (8) passes mesh (2), and dotted line (9) passes mesh (4), and the neighboring and the inner periphery of the guard after being shaped along dotted line (8), dotted line (9) backfin just form the broach shape.The backfin angle can be between 60 degree and 90 degree.Certainly curved tearing open also can become circular-arc, just becomes mildewed to stretch into efficient and tear open be not as curved as horn shape.The imagination is because peripheral position is to be used to shave remove become mildewed, so guard thickness can be thicker, to strengthen mechanical strength easily.With reference to Fig. 2, knife rest (10) has three groups of blades circumferentially respectively arranging every 120 degree, every group of blade formed radially being staggered by three narrower blades (11) blades (12) blades (13), the position that knife rest (10) is gone up the dress blade has finedraw, its thickness is slightly thicker than blade thickness, width is slightly wideer than blade width, so that blade can be moved up and down flexibly.Between each blade bottom and the knife rest little spring (14) is housed, blade is popped up with guard (1) closely contact, little spring (14) also can make little spring into.On each blade, stamp out at the outstanding little shell fragment (15) of blade face, each blade is stuck in the groove on the knife rest.Blade is worn into blade with the end that guard (1) contacts, and the right angle, both sides of blade is worn into circular-arc, to make the blade rotation more flexible.Each blade can be worn into the very little circular-arc blade that makes of radian a little and contact better with guard.With reference to Fig. 3, power supply can be with also available charging device of dry cell or external power supply, and power supply is connected to the two ends of motor by switch.The shaft extension of motor is gone into the borehole jack at knife rest (10) center and is lived, and motor reel is tightly overlapping a chuck and doing the circumference rotation to drive knife rest (10).Blade (11), blade (13) become miter angle to install with knife rest (10) approximately, and setting angle can with blade and guard be positive and contacts side surfaces pressure is done suitably to adjust.Blade (11), blade (13) position mill positive at guard (1) and contacts side surfaces has blade, the angle of both sides blade and guard (1) bend tear open angle one to.The center has an outstanding sphere to withstand the guard center above the knife rest (10), in order to avoid the stressed down distortion of guard is too severe.Guard (1) firmly combines with a circle basket, and the circle basket can be tightened on the body or by the mode of blocking and tightly be stuck on the body.Motor such as torque can be established a change-speed gearing inadequately and be strengthened torque.Existing manufacturing rotary shaver process materials is very ripe and general, and the present invention just can fine enforcement on existing process materials.
