Description

Domestic electric knife grinder

The utility model belongs to a kind of knife sharpening device that is specially adapted for the sharpening cutting edge.Be the electric knife sharpener of a kind of home-use cutter cutting edge grinding specifically.

In the CN2128576Y family expenses knife sharpener technology of known domestic bulletin, it is that the grinding tool assembly is being had on the framework of lid, and is furnished with handle.Mainly solved the antihygienic drawback of grinding tool appearance that use in common kitchen.Because the using method of this knife sharpener is to utilize the reciprocating motion that promotes cutter, reaches ground effect.But for the grinding of cutter, depending on simply, is not that anyone grasps in fact.One comes grinding angle bad, and on the contrary with blade blunt or rounding, thing gets that it is anti-; Two when coming grinding, controls badly, hinders hand easily and bring unnecessary danger, and thus, above-mentioned knife sharpening device can't satisfy the desirable apparatus as the family kitchen tool grinding.

In addition, the grinding tool device of market sale and use also has two kinds of versions, and a kind of is to utilize to have on the support of handle, and the some cutting blades of symmetrical overlapping installation become the V-type mouth, and the cutter sword is inserted reciprocating sliding in the V-type mouth, make the blade scraping sharp by cutting blade; Another kind is the inboard of two round rollers to be equipped with the taper catch and to be furnished with emery wheel with the middle part form the V-type mouth, during use blade put into the V-type mouth, promoting cutter freely rolls knife sharpener, reach the grinding edge because preceding a kind of sharpening form is scraping, makes it scraping place surface and slightly make, cutting edge has burr and too sharp, and it is not lasting to use; Plant the back because by the rolling wheel grinding, so the Grinding Contact face is little, and the friction of emery wheel and cutter is less in addition, the cutting edge grinding is not sharp, causes using unabiding defective equally.

The purpose of this utility model provides a kind of electric household knife sharpener, by the clamping device that contacts with cutter hub, moves and to have the knife sharpener that rotates bistrique, makes it the desirable apparatus that reaches safe, quick, easy to use.

For achieving the above object, technical solution of the present utility model is achieved in that and will be provided with micro machine in knife sharpener housing one end, makes it to be connected on the micro-motor by the neck bush that emery wheel is housed, and forms the power bistrique; Another handle end is hinged with the bearing support that has protruding pillow block, and utilizes the gathering sill of bearing support bottom to cooperate with the guide post that has movable clip, is clamped on the cutter by clip, in order to move freely the knife sharpener grinding.

The utlity model has following advantage:

1, adopt hand-held integral handle easily and dispose high-revolving micro machine and the guiding clamping device, have reasonable in designly, easy to use, ground effect is good.

2, owing to adopt locating guide device, during grinding, do not need whether to have experience and know-how and adjust grinding angle, only need the operation knife sharpener to move back and forth and get final product, avoided the operator to point the contact blade effectively, make it safe and reliable.

3, adopt neck bush to have mill shape claw, can change two abrasive grinding wheels quickly and easily, realize thick, fine ginding.

Description of drawings:

Fig. 1 is an electric household knife sharpener topology view;

Fig. 2 is the topology view of the head of whetting a knife.

Embodiment does concrete description in conjunction with the accompanying drawings:

See that Fig. 1 shows the fast body structure of family expenses sharpener, with knife sharpener housing 2 as being provided with small high speed motor 8 in one end of bistrique position, rotating speed is 2000 rev/mins, the neck bush 6 that emery wheel 5 is installed is connected on the micro-motor 7 kelly and the neck bush 6 open-ended fixedly composition power bistriques that have by micro-motor 7.Micro-motor 7 inserts when connecting, and because of neck bush 6 both sides have distortion claw 13, by the endoporus reducing at claw 13 positions and micro-motor 7 interference fit greater than the reducing place, two claws 13 is blocked emery wheel 5 to the both sides distending, sees Fig. 2.

Two shrinkage pools of the knife sharpener housing handle other end are hinged with the bearing support 3 that has protruding pillow block 4, and utilize the gathering sill of support 3 bottoms to cooperate with the guide post 10 of the clip 9 of the activity that has two symmetries, by a clip 9 is installed on the hole slot that guide post 10 has by bearing pin 11, utilize bearing pin 11 to act on the spring 12 of guide post 10 inner chambers, make it constitute the elastic clip leading truck, and be clamped on the cutter, carry out grinding in order to move freely knife sharpener.Simultaneously, knife sharpener integral body can be rotated along protruding pillow block 4 place's up times, make it two bodies and be launched into a vertical handle, in order to cutter or other grinding part of grinding plurality of specifications.In addition, also can utilize emery wheel 5 radial end face grindings.

Equally, break away from, except that above-mentioned guiding chucking cutter form, also can utilize in the gathering sill of bearing support 3 bottoms the magnet roller to be set or the magnet slide block comes direct adhesive contact cutter, the stability when the control knife sharpener moves for reaching knife sharpener and cutter contact preventing.

During use, elastic clip 13 is moved on the length of cutter hub chucking voluntarily, bearing support 3 gathering sills of knife sharpener are placed on the guide post 10, starting switch 1, emery wheel 5 rotation at a high speed, pressing down that the knife sharpener handle end freely moves back and forth can the grinding blade.The electric knife sharpener electrical source of power all can adopt the AC and DC double-purpose electric source.
