Abstract
The utility model discloses an electric sharpener, which comprises a motor, a transmission component, sharpening components, and a rotating shaft, wherein, the motor drives the sharpening components through the transmission component. The electric sharpener is characterized in that an elastic part is also included, the fixed end of the elastic part is fixed on the rotating shaft, and the movable end of the elastic part is connected with the sharpening components; under the elasticity of the elastic part, the movable end drives the sharpening components to flex along the axial direction of the rotating shaft. The two sharpening components of the electric sharpener are both connected with the rotating shaft through an elastic device, when a knife edge is arranged between the two sharpening components, under the action of the elastic device, the space between the two sharpening components can be automatically adjusted to match with the thickness of the knife edge without being adjusted by hand, so as to be convenient for using by people greatly.
Description
Technical field
The utility model relates to a kind of home-use electric knife sharpener.
Background technology
Existing electric knife sharpener, two sharpening components are separately fixed in two parallel rotating shafts, distance between rotating shaft can be carried out limited adjusting by adjusting screw(rod), rotating shaft is connected with gear train on the motor by transmission mechanisms such as belts, thereby make the output energy of motor pass to rotating shaft by gear train, drive sharpening component by rotating shaft and rotate, so the blade between two sharpening components is worn into sharp, as the disclosed boxlike electric knife sharpener of Chinese utility model patent CN2467260Y.There is following deficiency in this electric knife sharpener:
At first, sharpening component is separately fixed in two parallel rotating shafts, though can regulate the rotating shaft spacing by adjusting screw(rod), and then regulate two distances between the sharpening component, avoid making spacing excessive because of sharpening component is impaired; Simultaneously, when needing the thicker kitchen cutter of tool sharpening, suitably adjusting screw(rod) mates the distance of sharpening component and thickness of knife edge.But the progression of this adjusting is limited, and the accuracy of manual adjustment also be difficult to control, trouble operates.
Secondly, the gear train that need comprise a plurality of gears that is connected of motor and sharpening component makes the complex structure of knife sharpener, and volume is big, the cost height.
Summary of the invention
At the deficiencies in the prior art, the utility model aims to provide a kind of electric knife sharpener, and the distance between the sharpening component can be regulated automatically, and is easy to operate.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric knife sharpener, comprise motor, transmission component, sharpening component and rotating shaft, motor drives sharpening component by transmission component and rotates, it is characterized in that: also comprise elastic parts, the not moved end of elastic parts is fixed in the rotating shaft, and movable end is connected with sharpening component; Under the elastic force effect of elastic parts, it is flexible along the axial direction of rotating shaft that movable end drives sharpening component.
Described elastic parts is a spring assembly.
The not moved end of described spring assembly is a spring pedestal, and movable end is the base external member, and spring places in the spring pedestal, and the base external member is connected with spring pedestal by the chute that has back-off.
Described sharpening component is an emery wheel, and adopts seccotine to stick on the movable end of elastic parts.
Described transmission component is a mandrel connector, and this mandrel connector is connected the output shaft of motor point-blank with rotating shaft.
The not moved end of described elastic parts is socketed in an end of rotating shaft; The two ends of mandrel connector are hollow form, the output shaft of the two ends difference socket motor of hollow, the not moved end of elastic parts.
Above-mentioned electric knife sharpener also comprises the sharpening component loam cake, and this loam cake is provided with groove above sharpening component, and this groove favours the radial direction of rotating shaft.
The beneficial effects of the utility model are: two sharpening components all are connected with rotating shaft by elastic device, when blade places between two sharpening components, under the effect of elastic device, the spacing of two sharpening components can be adjusted to automatically with thickness of knife edge and be complementary, and do not need manual adjustment, greatly facilitate people's use.Secondly, motor rotates by the rotating shaft that mandrel connector drives sharpening component, adopts gear train to compare with prior art, and is simple in structure a lot.In addition, the groove of blade is placed in the utility model set being used in the sharpening component loam cake, and it favours the radial direction of sharpening component rotating shaft, and hold the custom that the cutter direction tilts in this and the people's daily life and match, thus the people's that are more convenient for use.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the exploded view of Fig. 1;
Fig. 3 is the utility model final assembly schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model comprises motor 1, elastic parts 3, sharpening component 4 and mandrel connector 2.Wherein sharpening component 4 is fixed on the elastic parts 3; Motor 1 is connected with elastic parts 3 by mandrel connector 2, and then drives sharpening component 4 with elastic parts 37 rotations around the shaft.
As shown in Figure 2, in the present embodiment, elastic parts 3 is a spring assembly, its not the moved end be spring pedestal 31, movable end is a base external member 33, and wherein spring pedestal is fixed in the rotating shaft 7, and spring 32 places in the spring pedestal 31, base external member 33 is connected with sliding shoe 311 on the spring pedestal 31 by chute 331, and chute 331 is provided with back-off 330 and prevents sliding shoe 311 disengaging chutes 331; Base external member 33 is slided along chute 331 when spring is done stretching motion.Sharpening component 4 is for having the emery wheel of centre bore 41, and the center projection 332 on centre bore 41 and the base external member 33 is complementary; Emery wheel pastes on the base external member 33 of spring assembly 3 by seccotine, and slides along chute 331 with base external member 33.
In the present embodiment, transmission component is a mandrel connector 2, and its two ends are hollow form, the output shaft 11 of the two ends difference socket motor of hollow, the bottom 310 of spring pedestal 31, thus output shaft 11 is connected point-blank with the rotating shaft 7 of sharpening component.In addition, rotating shaft 7 also is connected with bearing 6, and bearing 6 is fixed on the installing hole 91 of electric knife sharpener base plate 95, as shown in Figure 3 by bearing fixing part 5.
