Description

Electric knife sharpener

The utility model relates to a kind of electric knife sharpener.

At present, traditional sharpening mode is to whet a knife by manual action, wastes time and energy, and operates also dangerous.

In view of this, the purpose of this utility model provides a kind of electric knife sharpener,, drags grinding stone and moves as linear reciprocation through transmission system with motor, and the blade of fixing cutter is carried out grinding.

The purpose of this utility model is achieved in that it comprises casing, motor and rotating shaft, wherein, casing is provided with the elasticity point of a knife that clamping is whetted a knife, the motor shaft lower end of motor sets firmly a gear, and the lower end of rotating shaft sets firmly the gear that is meshed with gear, and the lower end of rotating shaft also sets firmly the connecting rod of a crank and pivot joint thereof; The pair of straight guide rail also is set on the casing; The other end of this connecting rod articulates a grinding stone frame, and this sets firmly a grinding stone above grinding stone frame, and its both sides all stretch out two and pick up the ears, and this picks up the ears respectively that sliding fit is nested with on corresponding straight guide; Set firmly a tank on the casing above the grinding stone, a bottom outlet is offered in this tank bottom.

The all sheathed helical spring of described straight guide two ends.

Owing to adopt such scheme: sharpening saves time and is laborsaving, and operation is safety also, and structure is also simple simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments schematic diagram.

The A of Fig. 2 the utility model exemplary embodiments Fig. 1 is to view.

Among the figure:

1, casing 11, elasticity point of a knife 111, sharpening

12, straight guide 121, helical spring 2, motor

21, gear 3, rotating shaft 31, gear

32, crank 33, connecting rod 4, grinding stone frame

41, grinding stone 42, pick up the ears 5, tank

51, bottom outlet

Present embodiment comprises casing 1, motor 2, rotating shaft 3, knife board 4 and tank 5, as shown in Figure 1 and Figure 2, and wherein:

Casing 1 is a metal shell, set firmly on it and put elasticity point of a knife 11, pair of straight guide rail 12, and its bottom is empty formula framework, during for sharpening, the water direct current flows out from the bottom, elasticity point of a knife 11, clamping whets a knife 13, the spring force of elasticity point of a knife 11 presses down whets a knife 111, and making whets a knife 13 well contacts the sheathed helical spring 121 of pair of straight guide rail 12 two ends with grinding stone 41.

Motor 2 vertically is fixed on the casing 1, and the motor shaft lower end of this motor 2 sets firmly a gear 21.

Rotating shaft 3 with bearing hinge joint on casing 1, this rotating shaft 3 is parallel with the motor shaft of motor 2, these rotating shaft 3 lower ends set firmly the gear 31 that the gear 21 on the motor shaft with motor 2 is meshed, in the rotating shaft 3 of these gear 31 lower ends, set firmly a crank 32 and coupled connecting rod 33 again, the other end of this connecting rod 33 is hinged on the rear end of grinding stone frame 4, therefore, and the rotation of motor 2, through gear 21,31, crank 32, connecting rod 33 drive grinding stone frame 4.

Grinding stone frame 4 is one flat plate framves, on it and an affixed grinding stone 41, and these grinding stone frame 4 both sides are all stretched out two and are picked up the ears 42 sliding fits on the pair of straight guide rail 12 on the casing 1, the sheathed helical spring 121 of the two ends of this guide rail 12 can reduce the startup of grinding stone frame 4 and the impact load that stops, and makes 4 motions of grinding stone frame steadily.

Tank 5 is suspended on the casing 1 of grinding stone 41 tops, and offers bottom outlet 51 in tank 5 bottoms, allows being filled with water in the tank 5, can constantly drop on the grinding stone 41 use when whetting a knife, (bottom outlet 51 can be blocked with rubber stopper when not whetting a knife, and is not shown).
