Stirring rod structure

Abstract

The utility model discloses a stirring rod structure which at least comprises a stirring cover, a plurality of airflow openings are formed in the peripheral wall of the stirring cover and used for enabling the interior of the stirring cover to be communicated with the exterior of the stirring cover, bending pieces are arranged on the portions, on the lower sides of the airflow openings, of the stirring cover, and the bending pieces are bent inwards to form concave spaces. And the concave space is communicated with the airflow port. Due to the arrangement of the concave space, air can be input into the stirring cover from the airflow opening and can also flow into the stirring cover from the concave space, so that the whole air circulation space is formed by overlapping the concave space and the airflow opening, and the air circulation space can be effectively enlarged so as to weaken vortexes; therefore, the suction force generated during crushing and stirring is weakened. And the handheld stirrer is prevented from being adsorbed on the inner bottom wall of the container during use.

Description

Technical Field

[0001] The utility model relates to a stirring rod structure. Background Art

[0002] The stirring rod is a part of the hand-held blender, which is mainly composed of a stirring cover and a blade head located inside the stirring cover. When in use, the user holds the hand-held blender by hand, extends the stirring rod into the interior of the container, and the blade head rotates at high speed to chop the materials in the stirring cover. Since the blade head rotates at high speed, eddy currents are generated, and the generation of eddy currents causes the stirring cover to be adsorbed on the bottom wall of the container. In order to reduce the suction problem caused by the eddy currents, in the prior art, air flow openings are provided on the peripheral wall of the stirring cover, and the air flow openings can allow the airflow inside and outside the stirring cover to circulate with each other. However, the existing air flow openings are all horizontal openings perpendicular to the rotation axis of the blade head. The setting of such air flow openings results in a relatively limited space for air circulation, and cannot effectively reduce the suction generated during stirring.

[0003] Based on the above, how to further reduce the stirring suction has become a technical problem to be solved in the prior art. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a stirring rod structure that can increase the air circulation space.

[0005] A stirring rod structure designed for this purpose at least includes a stirring cover, a plurality of air flow openings are arranged on the peripheral wall of the stirring cover, the air flow openings are used to connect the inside of the stirring cover with the outside, a bending part is arranged on the stirring cover at the lower side of the air flow opening, the bending part is bent inwardly to form a recessed space, and the recessed space is connected to the air flow opening.

[0006] Preferably, the stirring cover is connected to a columnar connecting piece, and the columnar connecting piece is connected to a stirring rod connecting head.

[0007] Preferably, a cutter head is provided in the stirring cover, a rotating shaft is rotatably provided in the columnar connecting member, one end of the rotating shaft extends into the stirring cover to be connected to the cutter head, and the other end of the rotating shaft extends into the stirring rod connecting head.

[0008] Preferably, a bearing is disposed inside the columnar connecting member, and the rotating shaft is rotatably disposed on the inner ring of the bearing.

[0009] Compared with the prior art, the utility model is provided with a bending piece on the stirring cover at the lower side of the airflow port, and the bending piece is bent inward to form a recessed space, and the recessed space is connected to the airflow port. When the blade head stirs and drives the gas to flow, the external air can enter the stirring cover from the lateral airflow port and the recessed space. With the setting of the recessed space, the air can not only be input into the stirring cover from the airflow port, but also flow from the recessed space to the stirring cover, so that the entire air circulation space is a superposition of the recessed space and the airflow port, which can effectively increase the air circulation space to weaken the vortex, thereby weakening the suction generated during crushing and stirring. Avoid the handheld blender being adsorbed on the inner bottom wall of the container during use. BRIEF DESCRIPTION OF THE DRAWINGS
