Description

Technical Field

[0001] This utility model relates to the field of electric household appliances, and in particular to a modified structure of a portable mixer. Background Technology

[0002] As disclosed in patent application 202510079854.1, existing portable stirrers that are easy to carry and use include a base with a power mechanism and a container with a stirring blade, the container being cylindrical in shape for easy hand gripping.

[0003] During operation, the base and container are connected together by the base snap-fit ​​and the container snap-fit. The material to be stirred is placed in the container, the lid is closed, and at the same time, the switch is turned on. The control device controls the power mechanism to drive the stirring blade to stir the material in the container.

[0004] This type of portable mixer is powered by a rechargeable battery. Because it is portable, it is not large in size, and the battery is not large in size, so the capacity cannot be large. Due to the limitations of the overall size of the product, the motor power is not very large, which makes it easy to get stuck by large pieces of material when mixing and crushing materials, and even prevents the mixing from being completed smoothly. Summary of the Invention

[0005] The purpose of this invention is to provide an improved structure for a portable mixer that is both easy to carry and use, and can effectively prevent the mixing blade from jamming, ensuring smooth mixing.

[0006] The improved structure of this portable stirrer is achieved as follows: it includes a base with a power mechanism and a cylindrical container with a stirring blade. The key feature is that the lower sidewall of the container bends inward, forming an obtuse angle between the lower and upper sidewalls at the bend. One side of the bend at the lower part of the container is higher than the other side, and the bend descends continuously from high to low. The rotation axis of the stirring blade deviates from the central axis of the cylindrical container towards the higher bend at the lower part of the container. The height of the bend at the lower part of the container is higher than the stirring blade, while the height of the bend at the other side is lower than the stirring blade.

[0007] When in use, the power mechanism drives the stirring blade to rotate, which stirs and breaks the material in the container. Because the rotation axis of the stirring blade deviates from the central axis of the cylindrical container at the bend on one side of the lower part of the container, and the lower side wall of the container bends inward, the mixed fluid forms a rotating vortex that tilts towards the bend on one side of the lower part of the container. Large pieces of material enter the working range of the stirring blade from the bend on the other side of the lower part of the container and are stirred and broken by the stirring blade. Then, they flow to the top of the stirring blade with the tilting rotating vortex.

[0008] Because the rotation axis of the stirring blade deviates from the central axis of the cylindrical container at the bend on one side of the lower part of the container, the material flowing over one side of the lower part of the container is less likely to get stuck on the stirring blade. Moreover, since the material flows above the stirring blade with the inclined rotating vortex, only the material on one side of the lower part of the container is acted upon by the stirring blade. Even if the motor power is low, as long as there is enough stirring time, it is sufficient to break up the material without it getting stuck. This effectively avoids jamming and ensures that the stirring is completed smoothly.

[0009] Preferably, the bend is a curved transition. Using a curved transition is convenient for manufacturing and also prevents the formation of dead corners where bacteria can accumulate (bending transitions can easily create dead corners where bacteria can accumulate).

[0010] Preferably, the bottom of the container is flat, and the periphery of the flat bottom of the container is connected to the lower part of the lower side wall of the container by an arc surface. Using an arc surface to connect the material fluid makes it easier to form a stable rotating vortex, which is beneficial to the mixing and crushing of the material.

[0011] Compared with existing technologies, this invention is convenient to carry and use, and can effectively avoid jamming of the stirring blade, ensuring smooth mixing. Attached Figure Description

[0015] The improved structure of the portable stirrer of this utility model will now be described in further detail with reference to the accompanying drawings and embodiments:

[0016] As shown in the figure, the improved structure of the portable stirrer of this utility model is achieved as follows: it includes a base 2 with a power mechanism 1, a cylindrical container 4 connected to the base 2 with a stirring blade 3 driven by the power mechanism 1, and a cover 5 at the upper end of the cylindrical container 4. The special feature is that the lower side wall of the container 4 is bent inward, so that the lower side wall 401 and the upper side wall 402 form an obtuse angle at the bend 403. The bend 403 on one side (right side) of the lower part of the container 4 is higher than the bend 403 on the other side (left side) of the lower part of the container 4, and the bend 403 is continuously lower from high to low. The rotation axis A of the stirring blade 3 is deviated from the central axis B of the cylindrical container 4 in the direction of the bend 403 on one side of the lower part of the container 4. The height of the bend 403 on one side of the lower part of the container 4 is higher than the stirring blade 3, and the height of the bend 403 on the other side of the lower part of the container 4 is lower than the stirring blade 3.

[0017] Preferably, the bend 403 is a curved transition.

[0018] Preferably, the inclination of the lower sidewall 401 below the bend 403 on one side (right) of the lower part of the container 4 is greater than the inclination of the lower sidewall 401 below the bend 403 on the other side (left) of the lower part of the container 4.

[0019] Preferably, the bottom of container 1 is flat, and the periphery of the flat bottom of the container is connected to the lower part of the lower side wall 401 of container 4 through an arc surface 404.

[0020] In use, the power mechanism 1 drives the stirring blade 3 to rotate, which stirs and crushes the material in the container 4. Since the rotation axis A of the stirring blade 3 deviates from the central axis B of the cylindrical container 4 at the bend 403 on one side of the lower part of the container 4, and the lower side wall 401 of the container 4 bends inward, the mixed fluid forms a rotating vortex that is inclined towards the bend 403 on one side of the lower part of the container 4. Large pieces of material enter the working range of the stirring blade 3 from the bend 403 on the other side of the lower part of the container 4 and are stirred and crushed by the stirring blade 3. Then, they flow to the top of the stirring blade 3 with the inclined rotating vortex.
