Description

Knife sharpener

Technical field

The utility model relates to knife sharpener.

Background technology

Present knife sharpener, its structure comprises: base, base is provided with motor, and the output shaft of motor is provided with emery wheel, and the top of emery wheel is provided with the crescent shaped case.During actual the use, will be resisted against with the cutting edge of blunt cutter on the sharpening face in the emery wheel outside and carry out grinding.Obviously, because operating personnel firmly can not accomplish complete uniformity in whole sharpening process, make that the uniformity that grinds the cutting edge that comes on this knife sharpener is relatively poor; And the metal fragment that produces in the sharpening process splashes everywhere, thereby ambient air is polluted.In addition, be in the dry grinding state between emery wheel and the cutter all the time, noise is bigger, and can produce a large amount of metal fragments, and is all totally unfavorable to cutter life-span itself and sharpening effect.

The utility model content

Technical problem to be solved in the utility model is: a kind of knife sharpener that blocks the most of metal fragment that produces when whetting a knife is provided.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: knife sharpener, comprise: base, base is provided with motor, the output shaft of motor is provided with emery wheel, also be provided with shell on the described base, described motor and emery wheel all cover in the shell fully, and the top of shell is provided with two sharpening mouths that match with the sharpening face of emery wheel both sides respectively.

Further technical problem to be solved in the utility model is: a kind of conforming knife sharpener of cutting edge that can improve greatly after grinding well is provided.

For solving above-mentioned further technical problem, the technical solution adopted in the utility model is: the side of described two medial and lateral of whetting a knife mouthful is respectively confined planes and the dependence face that matches with the institute knife milling tool.

Another technical problem to be solved in the utility model is: the knife sharpener that a kind of metal fragment amount that produces can reduce to whet a knife greatly the time is provided.

For solving the technical problem of above-mentioned another, the technical solution adopted in the utility model is: also be provided with water tank on the described base, the Lower Half of described emery wheel is in the water tank.

The beneficial effects of the utility model are: the utility model all covers on motor and emery wheel in the shell, two sharpening mouths that match with the sharpening face of emery wheel both sides have respectively only been offered at the top of shell, so just can block the most of metal fragment that produces when whetting a knife, thereby reduce its pollution surrounding air; Because the side in the interior outside of two mouths of whetting a knife is provided with confined planes and the dependence face that matches with the cutter of want grinding respectively, improved the cutting edge uniformity after mill is good greatly; In addition, by water tank is set, avoided the dry grinding between emery wheel and the cutter on base, the metal fragment amount of generation when having reduced greatly to whet a knife, and the water on the emery wheel can also play lubricated and prevent the cutter Effect of annealing, improve the sharpening effect, prolonged the service life of cutter.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

As Fig. 1, Fig. 2 and shown in Figure 3, knife sharpener described in the utility model, comprise:

base

1,1 is provided with motor 3 on the base, the output shaft of motor 3 is provided with emery wheel 4, for the rotation of emery wheel 4 more steady, on base 1, also be provided with bearing support 5, the output shaft expansion bearing of described motor 3 is in bearing support 5, also be provided with shell 8 on the described base 1, be movably set with the switch 2 of motor 3 in the shell 8, described motor 3 and emery wheel 4 all cover in the shell 8 fully, and the top of shell 8 is provided with and a left side that is positioned at emery wheel 4 both sides, the left side that right sharpening face matches, the

right mouth

81 and 82 of whetting a knife; The side of left and

right mouthfuls

81 and 82 the medial and lateral of whetting a knife is respectively confined planes and the dependence face that matches with the institute knife milling tool.

Fig. 4, Fig. 5, Fig. 6 show the another kind of structure of knife sharpener described in the utility model, this structure has comprised the structure of Fig. 1, Fig. 2 and knife sharpener shown in Figure 3, and changed the moulding of shell 8, made knife sharpener more attractive in appearance, and the left part of shell 8 is more prone to grip; Simultaneously, also shell 8 can be provided with left and

right mouthfuls

81 and 82 the right part of whetting a knife and increase, make it with such as some bigger kitchens such as kitchen knife cutter fit; As Fig. 5, shown in Figure 6, the metal fragment amount that produces in order to reduce to whet a knife, in described base 1, offer installing hole, being provided with positioning seat 6 in the installing hole---the mode that can bayonet socket be set by the edge at installing hole, buckle is set on positioning seat 6 is set together positioning seat 6 and base 1, positioning seat 6 is provided with water tank 7, and the Lower Half of described emery wheel 4 is in the water tank 7.In addition, detachable structure also can be arranged in the left and right position of whetting a knife between the

mouth

81 and 82 on the shell 8.

Be that example is described its course of work with Fig. 4, Fig. 5 and knife sharpener shown in Figure 6 below: in water tank 7, add an amount of water, then cutter is put into left side sharpening mouth 81, make the right side cutting edge of cutter abut on the left side sharpening face 41 of emery wheel 4, the left surface of cutter rests on the dependence face of left side sharpening mouth 81, after the right side cutting edge of cutter grinds, cutter is put into the right mouth 82 of whetting a knife, make the left side cutting edge of cutter abut on the right side sharpening face 42 of emery wheel 4, the right flank of cutter rests on the dependence face of the right mouth 82 of whetting a knife.The chip that produces in the friction process can deposit to the bottom of water tank 7 by current, after the end of whetting a knife, unloads positioning seat 6 from base 1, and the water tank 7 that is arranged on the positioning seat 6 is cleaned.
