Technical Field

The utility model relates to the technical field of stirrers, in particular to a kettle-shaped cup stirrer.

Background

The existing stirring cup is basically of a bucket-shaped structure with a big top and a small bottom, in terms of performance, when stirring, because the cup bottom is too small, massive food can only be positioned above the cutter assembly in the stirring process, the cutter assembly cannot effectively stir the cutter food, and meanwhile, because the cup bottom is too small, the bottom end is easily and quickly filled with crushed ice in the ice crushing process, ice cubes at the upper end cannot fall back into the stirring area of the cutter assembly, and the ice crushing effect is poor; in the aspect of safety, the upper end of the cup is too large, so that a hand can easily extend into the cup to be stirred and cut; in aspect of appearance: the stirring cup has high size and small volume utilization rate.

Moreover, no diversion rib is arranged in the existing stirring cup, and when the food materials are stirred, the flowing track of the food materials is as shown in figures 1-2: fig. 1 shows a horizontal trajectory state of the food material flow, and fig. 2 shows a vertical trajectory state of the food material flow.

In the horizontal direction, the food material stirring flow path in the stirring cup 10A is a movement path which is formed by taking the knife assembly 20A as a rotation center and is eccentric to the cup wall, and then is a circular movement path along the inner wall of the stirring cup 10A.

In the vertical direction, because the knife assembly 20A has a bending angle in the vertical direction, the food material in the stirring cup 10A follows the horizontal centrifugal force to be an upward movement track along the cup wall toward the cup cover, and then falls back due to gravity after impacting to the cup cover and encountering a barrier.

From the stirring effect analysis: in the horizontal direction, with knife tackle spare 20A apart from the cup wall closest point, the orbit that forms around the rotation center is the D circle of form, the edible material in the D circle of form can be effectively stirred the bits of broken glass, and the outer can not effectively stirred of D circle of form, vertical direction, the interior edible material of cup is along cup wall to the impact of bowl cover edge along horizontal direction centrifugal force, easily lead to bowl cover periphery adhesion food or edge to spill over, and because of small end cup height food fall back the orbit long, therefore, on the whole, the stirring cup 10A stirring effect of the no water conservancy diversion muscle of prior art is poor, eat and easily rush to on the bowl cover or overflow along the edge.

In order to make the stirring effect better, products designed with flow guide ribs gradually appear, such as Chinese patent numbers: 201821261450.6 discloses a strong vortex cooking machine, including base, stirring cup, the base is equipped with by motor drive's blade holder, the stirring cup be equipped with blade holder transmission complex stirring sword, the stirring cup includes glass cup and base, end cover top be equipped with the end cover mouth of cup mouth butt joint, end cover is heat-resisting heat conduction material, end cover lateral wall periphery is equipped with the heat-generating body, end cover lateral wall internal surface is equipped with bellied vortex muscle, this vortex muscle has mainly changed the direction of motion behind the food striking cup inner wall on the horizontal direction, however, after the direction change, whether food can get into again effectively stir the region unknown, the cup is narrow bucket form under being wide simultaneously, has the stirring bulk food difficulty or garrulous ice volume that the aforesaid said limited, the hand is stretched into the problem that the cup was cut by the stirring easily.
