[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a small grater with a simpler control structure and a lower failure rate.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A small grater comprises a main board, a side board is arranged at the outer edge of the main board, a plug-in column is arranged in the middle of the main board, an opening, a slicing knife and a shredding hole are arranged on the main board, the blade of the slicing knife is located above the opening, the blade of the slicing knife extends from the plug-in column to the side board, the shredding hole is arranged in front of the blade of the slicing knife, a shredding knife seat, a shredding cover plate, a shredding push rod and a rotating seat are arranged below the main board, the shredding knife is fixedly connected to the upper end of the shredding knife seat, the shredding knife can pass through the shredding hole and extend out of the upper side of the main board, and is characterized in that:

[0008] The shredding cover plate is formed with a cylindrical guide seat, and the inner side wall of the guide seat is formed with a plurality of guide protrusions protruding inwardly, and a guide slide groove parallel to the central axis of the guide seat is formed between adjacent guide protrusions, and a limited stopper is arranged at the lower end of the guide slide groove, and a lower slider protruding outwardly is formed on the outer peripheral wall of the shredding push rod, and the lower slider can be inserted into the guide slide groove and reciprocate along the guide slide groove, and a sawtooth protrusion is formed on the upper end of the shredding push rod; The lower end is rotatably connected to a rotating seat, and an upper slider protruding outward is formed on the outer peripheral wall of the rotating seat. The upper slider can be inserted into the guide groove and slide back and forth along the guide groove. The lower end of the upper slider protrudes from the lower side surface of the rotating seat and extends inward. The lower end of the upper slider is provided with an inclined upper guide surface, and the upper end of each guide protrusion is provided with a first lower guide surface and a second lower guide surface cooperating with the upper guide surface, and the upper guide surface can respectively abut against the serrated protrusion and the guide protrusion.

[0009] When the shredder in the small grater is not working, slicing action can be achieved. When the shredder extends out from the upper side of the main board, shredding action can be achieved. The user can flexibly switch between slicing and shredding according to needs. The small grater realizes the lifting and resetting of the shredder seat through the cooperation of the guide seat, the shredder push rod and the rotating seat. The structure is simple, the operation is convenient and the failure rate is low.

[0010] The working principle of the control structure of this small grater is as follows:

[0011] In the initial state, the lower slider of the wire cutting push rod is located in the guide slot and abuts against the limit block, the upper slider of the rotating seat is located in the guide slot, the upper guide surface of the upper slider abuts against the convex tooth side wall of the sawtooth protrusion, and the upper slider has a tendency to rotate and move downward along the convex tooth side wall, and the wire cutting knife is located at the lower side of the main board;

[0012] The lower end of the wire cutting push rod is pressed to push the wire cutting push rod upward, so that the upper slider is separated from the guide slot, and rotates and moves downward along the side wall of the convex tooth to fall onto the first lower guide surface, and then moves along the first lower guide surface until it abuts against the vertical stop surface between the first lower guide surface and the second lower guide surface. At this time, the rotating seat pushes the wire cutting knife upward out of the upper side of the main board and maintains the extended state;

[0013] When the wire cutter needs to be reset, just press the lower end of the wire cutter push rod again to push the wire cutter push rod upward, so that the serrated protrusion abuts against the upper guide surface of the upper slider and then push the upper slider to the upper side of the second lower guide surface. The upper slider will rotate and move downward along the side wall of the convex tooth and fall onto the second lower guide surface, and then move along the second lower guide surface into the guide groove. Finally, under the action of gravity, the upper slider moves downward along the guide groove, and the wire cutter follows the wire cutter seat to move downward and move to the lower side of the main board.

[0014] In the above-mentioned small grater, a positioning column is fixedly connected to the lower side of the shredder seat, and a positioning circular groove is provided at the upper end of the rotating seat. The positioning column is plugged into the positioning circular groove and the rotating seat can rotate relative to the positioning column.

[0015] The above-mentioned positioning column and positioning circular groove cooperate to play a role in circumferential positioning of the rotating seat, avoiding the horizontal position of the rotating seat from shifting during the up and down movement and circumferential rotation. The structure is simple, which is beneficial to improving the stability of the small grater during operation and reducing the failure rate.

[0016] In the above-mentioned small grater, the lower end of the rotating seat is fixedly connected to a positioning rod, and the positioning rod is coaxially arranged with the rotating seat. The lower end of the upper sliding block extends inward to the outer peripheral wall of the positioning rod. The upper end of the shredding push rod is provided with a positioning hole, and the positioning rod can be inserted into the positioning hole and rotate relative to the shredding push rod.

[0017] The cooperation between the above-mentioned positioning rod and positioning hole can make the rotating seat and the wire cutting push rod have better coaxiality, so that the upper guide surface of the upper slider can better cooperate with the serrated protrusion, the guide groove, the first lower guide surface and the second lower guide surface, so as to realize the lifting and resetting of the wire cutting knife, with a simple structure and a low failure rate; at the same time, it can also further play a role in circumferential positioning of the rotating seat, and avoid the horizontal position of the rotating seat from shifting during the up and down movement and circumferential rotation.

[0018] In the above-mentioned small grater, there are three guide protrusions, guide grooves, upper sliders and lower sliders, and six serrated protrusions. The guide protrusions are arranged in a circular array with the central axis of the guide seat as the center, and the upper slider is arranged in a circular array with the central axis of the rotating seat as the center. The lower slider and the serrated protrusions are both arranged in a circular array with the central axis of the shredding push rod as the center. The central axis of the lower slider, the central axis of the convex teeth corresponding to the serrated protrusions and the central axis of the shredding push rod are all located on the same vertical plane.

[0019] When the small grater is working, no matter the upper slider is located in the guide groove or on the first lower guide surface, when the serrated protrusion abuts against the upper slider, the raised side wall on the serrated protrusion with the same inclination direction as the upper guide surface abuts against the lower part of the upper guide surface, thereby ensuring that the upper slider can slide downward along the inclination direction of the upper guide surface and enter the first lower guide surface or the second lower guide surface after it leaves the guide groove or the vertical blocking surface.

[0020] The design of the number of the guide protrusions, guide grooves, upper and lower sliders, and serrated protrusions enables the rotating seat to complete the lifting or resetting action by rotating a small angle each time. It has a simple structure, is easy to operate, has high stability, and has a low failure rate.

[0021] In the above-mentioned small grater, a spring for driving the shredder seat to move downward is arranged between the shredder seat and the main board.

[0022] The design of the spring can make the reset of the shredder smoother, has a simple structure, and can significantly reduce the problem of jamming caused by reset relying solely on gravity, thereby reducing the failure rate.

[0023] In the above-mentioned small grater, at least two guide posts are arranged on the lower side of the main board, the shredder seat is provided with guide holes matched with the guide posts, and the spring is sleeved on the guide posts.

[0024] The design of the guide column can make the up and down movement of the wire cutter seat more stable, avoid deflection of the wire cutter seat during the up and down movement, and avoid the problem that the wire cutter cannot be aligned with the wire cutting hole. The structure is simple and can significantly reduce the failure rate. At the same time, the spring is sleeved on the guide column to avoid displacement of the spring after being squeezed, which can further improve the stability during operation and reduce the failure rate.

The main slicing knife is arranged at intervals along the radial direction of the main board, and the blade of the main slicing knife is arranged on the side away from the slicing knife. The distance between the blade of the secondary slicing knife and the central axis of the main board is greater than the distance between the corresponding blade of the main slicing knife and the central axis of the main board.

[0026] The shredder includes a main shredder and an auxiliary shredder. The main shredder and the auxiliary shredder cooperate to process the material into thinner pieces. The shredder has a simple structure and high stability.

[0027] In the above-mentioned small grater, the shredder seat includes a main shredder seat and a secondary shredder seat, the main shredder is fixed on the main shredder seat, and the secondary shredder is fixed on the secondary shredder seat, and at least two guide holes are provided on the main shredder seat and the secondary shredder seat, and guide columns that cooperate with the guide holes are formed on the lower side surface of the main board, and positioning columns are provided on the lower side surfaces of the main shredder seat and the secondary shredder seat, and each positioning column is provided with a rotating seat, and two guide seats are provided on the shredder cover plate, and each guide seat is provided with a shredder push rod that cooperates with the corresponding rotating seat.

[0028] The shredder seat includes a main shredder seat and a secondary shredder seat, and the main shredder knife and the secondary shredder knife can be controlled separately. When only the main shredder knife or the secondary shredder knife is working, the material can be processed into thick shredders. When the main shredder knife and the secondary shredder knife are working at the same time, the material can be processed into thin shredders. The shredder can be flexibly adjusted between thick shredders and thin shredders according to actual needs.

[0029] In the above-mentioned small grater, a partition is provided on the lower side of the main board, the shredding cover is clamped and fixed to the lower end of the partition and the lower end of the side plate, the main board, the partition, the side plate and the shredding cover together form a control cavity, the opening is not connected to the control cavity, and a plurality of water holes are provided on the shredding cover.

[0030] The design of the partition plate can make the control chamber relatively independent, preventing materials from entering the controller, and the design of the water hole can discharge the water stains that enter the control chamber through the shredding hole during the cleaning process.

[0031] In the above-mentioned small grater, it includes a handheld cover body and a storage box, the upper end of the storage box is open, the storage box is detachably connected to the lower edge of the side plate, and downwardly protruding positioning teeth are arranged on the lower side of the handheld cover body.

When the shredder 3 in the small grater is not working, the slicing action can be realized. When the shredder 3 extends out from the upper side of the main board 1, the shredding action can be realized. The user can flexibly switch between slicing and shredding according to needs. The small grater realizes the lifting and resetting of the shredder seat 4 through the cooperation of the guide seat 51, the shredder push rod 6 and the rotating seat 7. The structure is simple, the operation is convenient and the failure rate is low.

[0049] like Figure 7 As shown, a positioning column 41 is fixedly connected to the lower side of the shredder seat 4, and a positioning circular groove 72 is provided at the upper end of the rotating seat 7. The positioning column 41 is plugged into the positioning circular groove 72, and the rotating seat 7 can rotate relative to the positioning column 41.
