Description

Stirring blade with concave type cutting edge and handheld stirrer

Technical Field

The utility model relates to a cutter technical field, more specifically the hand-held type mixer that relates to a stirring blade of concave formula cutting edge and applied this stirring blade that says so.

Background

The cutter is a tool for cutting, the structures of the cutters used in different fields are different, and the cutter is applied to household appliances such as a blender, a juicer and a food processor, and is generally a two-blade cutter, a three-blade cutter, a four-blade cutter and the like which are well known by the public, and the purpose of cutting food materials is achieved through high-speed rotation of the cutter in liquid.

The cutting effect is different according to different cutter types of the cutter; the cutting edges of the conventional cutter have a linear shape, a convex arc shape or a combination of the linear shape and the convex arc shape.

As shown in fig. 1, the cutting edge a of the cutter 001 in fig. 1 is linear, and when the cutter 001 rotates clockwise, the food material is cut by the cutting edge a, and simultaneously moves correspondingly in the direction indicated by the arrow in fig. 1, and collides with the inner wall of the corresponding mixing cup under the action of centrifugal force;

as shown in fig. 2, the cutting edge B of the cutter 002 in fig. 2 is a convex arc, when the cutter 002 rotates clockwise, the cutting edge B in the food material cuts, and the food material correspondingly moves along the direction shown by the arrow in fig. 2, and collides with the inner wall of the corresponding mixing cup under the action of centrifugal force;

as shown in the patent number: 2016800358822, the cutting tool 003 of this patent is constructed as shown in fig. 3, in which the cutting edge C of the cutting tool 003 is a combination of a straight line shape and a convex arc shape, and the food material is cut by the cutting edge C while moving correspondingly in the direction indicated by the arrow and colliding with the inner wall of the corresponding mixing cup by centrifugal force;

when the three different knife shapes are used, the cut food materials quickly leave the knife edge area due to the action of centrifugal force and then collide with the inner wall of the stirring cup, the food materials possibly collide with the knife edge again due to the rebound of the inner wall of the stirring cup, and the more the collision frequency of the food materials and the knife edge in unit time is, the better the cutting effect is; in order to make the food stay as long as possible in the blade edge region so as to increase the cutting frequency of the blade, and finally achieve the purpose of increasing the cutting efficiency, the applicant proposes the following patent applications.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a stirring blade and hand-held type mixer of concave type cutting edge.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a stirring blade with a concave cutting edge, comprising: a sword leaf for connecting the installation department of pivot and at least one use the installation department as the radial extension of center, the sword leaf set up the cutting edge towards direction of rotation, constitute the back of a knife blade dorsad, the cutting edge to the setting of the back of a knife blade direction indent. The indent of cutting edge sets up the structure in this structure, compares with the cutter of traditional straight line shape cutting arris, can increase the length of cutting edge for the edible material of cutting up is longer than the cutter of traditional straight line shape cutting arris or protruding arc cutting arris in the cutting edge position dwell time of indent, has improved cutting frequency.

In a further technical scheme, the cutting edge is arc-shaped and concave towards the direction of the knife back; the concrete structure that the cutting edge indent set up has been optimized, under traditional cutter structure, eats the material and can leave the sword district at the effect of centrifugal force, nevertheless cutting edge arc indent sets up in this technique and makes eating the material be the vortex rotation after bumping with the cutting edge, and the time that stops in the sword district is longer.

In a further technical scheme, the cutting edge comprises: the cutting edge is connected with the edge surface, and the edge surface is positioned on one end surface of the knife blade and extends from the cutting edge to the knife back; the blade surface is obliquely arranged from the cutting edge to the direction of the knife back, and the thickness of the joint of the blade surface and the cutting edge is the minimum; the cutting edge extends from the connecting end of the blade and the mounting part to the other end. The above description specifically describes the specific structure of the blade.

In a further technical scheme, the mounting part is provided with a hole for connecting the rotating shaft, and the connecting hole is used for connecting the rotating shaft of the equipment when the stirring blade is mounted.

A hand mixer comprising a mixing blade according to any one of claims 1 to 6.

Known through foretell technical scheme, compare with prior art, the beneficial effects of the utility model reside in that: the cutting edge of the traditional stirring blade is improved into a concave arc shape, so that the length of the cutting edge is increased, and the contact between food materials and the cutting edge is increased; meanwhile, due to the fact that the arc-shaped concave edge is arranged, the stirring blade pushes the food materials to rotate in a vortex mode when rotating, the food materials stay in the edge area as long as possible, the cutting frequency of the stirring blade for the food materials is improved, and the purpose of improving cutting efficiency is finally achieved.
