Description

The electric household knife sharpener

The utility model relates to daily living article, is specifically related to a kind of electric household knife sharpener.

Present many families cutter such as sharpen a kitchen knife still adopts water is watered the old way of whetting a knife on stone, wastes time and energy.Though the family expenses knife sharpener of many types had successively been sold in market in recent years, all because of existing more shortcoming to be difficult to promote.(notification number: CN2199007Y), its shortcoming is to drive with manpower, and not only effect is low, and the difficult mill of the cutting edge at cutter two is sharp as China's patented product " a kind of kitchen used knife tool fast knife sharpener "." a kind of hand electric knife sharpener: (notification number: CN2319170Y), its shortcoming is that grinding wheel and motor rotary shaft and support all bond together, so but cannot change new grinding wheel when grinding wheel may wear to again for another example.Use dry cell very uneconomical as power supply.Stability is poor, and cutting edge easily produces during grinding on grinding wheel beats, and then can cause shutdown again when exerting oneself when excessive, uses inconvenient.

The purpose of the utility model is in order to overcome the shortcoming that above product exists, and the different cutting angles that design a kind of can the grinding knife tool cutting edge, can change grinding wheel, effect height, novel household electric knife sharpener easy to use.

The purpose of the utility model is realized by following technical scheme:

Miniature cocurrent electromotor (7), switch (9) and supply hub (10) are installed in respectively in the upper end of plastic casing (8), in the lower end, side and the afterbody lower end.The angle adjustment plate of two symmetries (2) is stuck in the both sides of edge of a knife locating cover (3) upper end, all there is circular arc undercut track at 4 contacts side surfaces places, can make angle adjustment plate (2) rotation regulate required angle, use 4 screws angle adjustment plate (2) to be tightened again respectively and be fixed on the edge of a knife locating cover (3) by arc-shaped slot.Edge of a knife locating cover (3) is stuck in outside the upper end of plastic casing (8).Screw is passed the circular hole of shrinkage pool on the grinding wheel (1) and emery wheel upper bracket (4) bottom, and be fixed together with nut screwing clamping.The slotted eye of emery wheel lower carriage (6) bottom is passed in the rotating shaft of DC micromotor (7) that has notch and silk mouthful, and be fixed together with nut screwing clamping.Stage clip (5) is put in the emery wheel lower carriage (6), colluded the emery wheel upper bracket (4) of groove and inject and to have on the emery wheel lower carriage (6) of protruding bolt having elasticity again, and can slide up and down.During work, the rotating shaft of grinding wheel (1), emery wheel upper bracket (4), stage clip (5), emery wheel lower carriage (6), miniature cocurrent electromotor (7) is combined into the integral body of a rotation.

The utility model is described in further detail below in conjunction with accompanying drawing and an embodiment:

Accompanying drawing is the front view of the utility model electric household knife sharpener, and wherein (1) is that grinding wheel, (2) are that angle adjustment plate, (3) are that edge of a knife locating cover, (4) are that emery wheel upper bracket, (5) are that stage clip, (6) are that emery wheel lower carriage, (7) are that 12 volts of miniature cocurrent electromotors, (8) are that plastic casing, (9) are that switch, (10) are supply hubs.

One an ac-dc power supply is inserted 220 volts of AC powers, the other end has been converted in the plug reeve supply hub (10) of 12 volts of dc sources again.Angle adjustment plate (2) rotated and be fixed on needed cutting edge cutting angle position.Generally hold the fuselage waist and increase the stability of complete machine on work top with left hand.The right hand cutter handle of holding with a firm grip, the edge of a knife one side that tilts is placed on the position of center line of grinding wheel (1) and grinding wheel (1) toward pressing to horizontal frame on the edge of a knife locating cover (3) along last, can prevent to exert oneself to cause when excessive shutdown like this.Again the same side of cutter is abutted on the angle adjustment plate (2) of homonymy.Press switch (9) connection power supply and make 12 volts of miniature cocurrent electromotors (7) work.Grinding wheel (1) is close to a side grinding of cutting edge under the elastic force effect of stage clip (5).Same quadrat method, but the another side of grinding cutting edge.The two sides of cutting edge roundness front and back are respectively done even mobile grinding back and forth, and general only need just can get the cutting edge grinding very smooth sharp in about 2 minutes.If change grinding wheel (1), only need back out screw and reinstall and get final product, easy to use.
