Description

A dicer blade TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vegetable and fruit processing and relates to a dicer blade. BACKGROUND

[0002] The dicer blade is an essential component of the dicer, and the existing dicer is mostly a grid-shaped structure composed of horizontal knives and vertical knives. For example, the utility model patent CN 206896278 U (publication date: January 19, 2018) discloses a vegetable and fruit dicer, which comprises a box body in the form of a square box without a cover. The top of the box body is provided with a top cover, the top surface of the rear end of the top cover is provided with a platform higher than the front end of the top surface of the top cover, the left and right sides of the platform at the rear end of the top cover are each provided with a vertically arranged stand, and a wiping knife is arranged between the two stands. The left and right ends of the middle part of the top cover are transversely provided with hinge shafts, the hinge shafts are each hingedly connected with a connecting rod perpendicular to the hinge shaft, the top ends of the two connecting rods are connected with a pressing plate, a plurality of pressing heads are arranged on the front side surface of the pressing plate, the top surface of the front end of the top cover is provided with a grid knife plate mounting port, and the grid knife plate mounting port is provided with a grid knife plate formed by a plurality of knives arranged longitudinally and transversely. When the pressing plate and the connecting rod are rotated along the hinge shaft and buckled at the front end of the top cover, the pressing heads can be pressed into the grids on the grid knife plate.

[0003] The horizontal knives and the vertical knives of the existing dicer blade have the same specifications, only one knife back is slotted and one knife edge is slotted, and the slotting depth is about half of the width of the blade. After the horizontal knives and the vertical knives are inserted into each other, the knife edge end surfaces of the two are flush. However, since one of the knives is slotted on the knife edge side, the strength of the knife is obviously lower than that of the other knife, and the knife with the slotted knife edge is very easy to be damaged during use. UTILITY MODEL CONTENTS

[0004] The utility model discloses in view of the deficiency of the prior art, provides a kind of dicer blade, with the advantages of high strength, long life.

[0005] To solve the above technical problems, the purpose of the utility model is realized by the following technical scheme:

[0007] In the above-mentioned dicer blade, preferably, the upper knife knife edge end surface exceeds the lower knife knife edge end surface by 0.2-0.8mm.

[0008] In the dicer blade, the upper slot has a slot depth less than the slot depth of the lower slot.

[0009] In the dicer blade, the lower blade has a thickness greater than the thickness of the upper blade, the upper slot has a slot width greater than the slot width of the lower slot, the thickness of the lower blade is adapted to the slot width of the upper slot, and the thickness of the upper blade is adapted to the slot width of the lower slot.

[0010] In the dicer blade, the lower blade has a width greater than the width of the upper blade.

[0011] In the dicer blade, the frame comprises a ring-shaped blade seat and a ring-shaped cover plate, the inner side of the blade seat is provided with a ring-shaped mounting plate, the mounting plate is provided with a plurality of upper open mounting slots, the blade assembly is inserted into the mounting slots, and the cover plate is arranged above the blade seat and fixes the blade assembly.

[0012] In the dicer blade, the two ends of the lower blade on the back side are provided with avoidance grooves matched with the cover plate, and the end surface of the lower blade is not higher than the cover plate as a whole, and the end surface of the lower blade at the avoidance grooves is not higher than the mounting plate.

[0013] In the dicer blade, the two ends of the upper blade and the lower blade are provided with fixing holes, and a fixing rod is arranged in the fixing holes, and the fixing rod is arranged in the cavity between the blade seat and the mounting plate after assembly.

[0014] Compared with the prior art, the dicer blade has the following beneficial effects:

[0015] 1. The dicer blade has different specifications of the upper blade and the lower blade, and after assembly, the upper blade edge end surface exceeds the lower blade edge end surface, so that when cutting food, the upper blade edge first contacts the food, and the lower blade edge contacts the food after further pressing down. Through this arrangement, the upper blade edge becomes the main pressure bearing edge, the pressure borne by the lower blade edge is reduced, and the relatively low-strength lower blade is prevented from being damaged. Therefore, the dicer blade has the advantages of high strength and long service life.

[0016] 2. The upper blade and the lower blade are further designed differently, the thickness and width of the lower blade are increased, the strength of the lower blade is further improved, the strength of the dicer blade is higher, and the service life is longer. BRIEF DESCRIPTION OF DRAWINGS
