Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and in particular relates to a cutter head assembly and a mixer. Background Art

[0002] A blender is a device for crushing and juicing fruits and vegetables. During use, a handheld blender is used to extend the blade assembly of the blender into a cup, and the blades inside the blade assembly rotate to crush and juice the fruits and vegetables in the cup. However, in the prior art, during juicing with a blender, the end of the blade assembly is in a flat state. Due to the negative pressure generated between the blade assembly and the cup, the blade assembly spontaneously adsorbs the bottom of the cup during the juicing process, which is called the cup suction phenomenon. In addition, an opening or uneven surface is provided at the end of the blade assembly. During the juicing process, the liquid generated by the juicing is in a rotating state. When the liquid hits the cup, it will drive the cup to rotate, resulting in the cup moving with it, which affects the juicing operation. Utility Model Content

[0003] The purpose of the present utility model is to provide a cutter head assembly and a blender to solve the above-mentioned technical problems. A connecting structure connected to the cavity is provided above the cutter head to provide a channel for liquid flow when the cutter head assembly is operating in the cup, thereby reducing the negative pressure generated by the cutter head assembly on the cup and avoiding the problem of adsorption of the cup. During the rotation of the cutter head, the liquid rotates with the rotation of the cutter head. The connecting structure is provided above the cutter head to prevent the rotating liquid from colliding with the inner wall of the cup in the radial direction, thereby avoiding the problem of the cup moving with the cutter head assembly.

The connecting structure provided above the blade provides a passage for liquid flow while the blade assembly is operating within a cup, thereby reducing the negative pressure exerted by the blade assembly on the cup and preventing the cup from being adsorbed. During the rotation of the blade, the liquid rotates with the blade. The connecting structure provided above the blade prevents the rotating liquid from striking the inner wall of the cup in a radial direction, thereby preventing the cup from moving with the blade assembly.

The stirring base 1 is provided with a cavity 10 providing a rotational space for the blade 2. The stirring base 1 is provided with a connecting structure connected to the cavity 10 above the blade 2. The connecting structure connected to the cavity 10 above the blade 2 provides a channel for liquid flow when the blade assembly is operating in a cup, thereby reducing the negative pressure generated by the blade assembly on the cup and avoiding the problem of cup adsorption. During the rotation of the blade 2, the liquid rotates with the rotation of the blade 2. The connecting structure is provided above the blade 2 to prevent the rotating liquid from colliding with the inner wall of the cup in the radial direction, thereby avoiding the problem of the cup moving with the blade assembly.

[0035] In the radial direction of the rotation of the blade 2, the projection of the connecting structure does not overlap with the projection of the blade 2. The connecting structure is positioned above the blade 2 on the stirring base 1. The stirring base 1 does not have a hole where the blade 2 is positioned. The connecting structure is positioned above the blade 2 to prevent the rotating liquid from striking the inner wall of the cup in the radial direction, thereby preventing the cup from moving during operation of the blade assembly.

[0036] The cutter head 2 is fixedly connected to the rotating shaft 20, and the rotating shaft 20 is movably connected to the stirring base 1.
