3 to 6 are a front view, a rear view, a left view, a top view, and a bottom view showing a first blade 410 according to one embodiment of the present disclosure.

In some embodiments, the first blade 410 may have a central through-hole penetrating the first blade 410 along a thickness direction crossing the first axis of rotation, and may have a shape in which the body is formed only on the rim. In addition, the first blade 410 may have a shape twisted in a spiral shape at a predetermined angle along the first rotation axis with the first rotation axis as a twist axis.

In some embodiments, the first blade 410 may include two vanes formed to radially protrude from the first axis of rotation. Here, the two vanes may achieve rotational symmetry. In some embodiments, the two vanes may achieve 2-fold rotational symmetry.

The first blade 410 not only moves the material to be stirred from side to side, but also the leading surface 413 of the twisted first blade 410 sends the material to be stirred downward to promote the convective movement of the material to be stirred up and down. The stirring efficiency of the target material can be further increased. Here, as the twist angle of the first blade 410 increases, convective movement of the material to be stirred in the vertical direction increases and rotation in the horizontal direction decreases, so that the twist can be set by an appropriate angle according to the purpose of stirring.

The first blade 410 may have an upper surface 415 and a lower surface 417 at both ends in the direction of the first axis of rotation. In addition, the first blade 410 may have a leading face 413 and a trailing face 411 that is the reverse side based on the rotation direction. In some embodiments, a tapered surface 419 is formed between the leading surface 413 and the bottom surface 417 of the first blade 410, so that the thickness of the first blade 410 increases toward the bottom surface 417. can decrease This configuration increases the fluidity of the material to be stirred between the bottom surface 417 of the first blade 410 and the bottom surface of the container 310, so that the material to be stirred is pressed against the bottom surface of the container 310. This can prevent sticking.

In some embodiments, on a cross section perpendicular to the first axis of rotation, the leading surface 413 of the first blade 410 may have a concave profile and the trailing surface 411 may have a convex profile. Accordingly, a cross section of the first blade 410 orthogonal to the first axis of rotation may have an approximately S-shape.

In some embodiments, a twist direction of the bottom surface 417 of the first blade 410 relative to the top surface 415 may be opposite to the rotation direction.

7 to 10 are a front view, a rear view, a left view, a top view, and a bottom view showing a second blade 420 according to embodiments of the present disclosure.

In some embodiments, the second blade 420 may have a shape twisted in a spiral shape at a predetermined angle along the second rotation axis with the second rotation axis as a twist axis. The second blade 420 may be twisted in a direction opposite to the twist direction of the first blade 410 .

However, in some alternative embodiments, the second blade 420 may have a central through-hole penetrating the second blade 420 along a thickness direction transverse to the second axis of rotation, similarly to the first blade 410. .

In some embodiments, the second blade 420 may include two vanes protruding radially from the second axis of rotation. Here, the two vanes may achieve rotational symmetry. In some embodiments, the two vanes may achieve 2-fold rotational symmetry.

The second blade 420 not only moves the material to be stirred left and right, but also the leading surface 423 of the twisted second blade 420 sends the material to be stirred downward to promote the up and down convective movement of the material to be stirred. The stirring efficiency of the target material can be further increased. Here, as the twist angle of the second blade 420 increases, convective movement of the material to be stirred in the vertical direction increases and rotation in the horizontal direction decreases, so that the twist can be set by an appropriate angle according to the purpose of stirring.

The second blade 420 may have an upper surface 425 and a lower surface 427 at both ends in the direction of the second axis of rotation. In addition, the second blade 420 may have a leading surface 423 that goes ahead and a trailing surface 421 that is the rear surface based on the rotation direction. In some embodiments, a tapered surface 429 is formed between the leading surface 423 and the bottom surface 427 of the second blade 420, the thickness of the second blade 420 toward the bottom surface 427 may decrease. This configuration increases the fluidity of the material to be stirred between the bottom surface 427 of the second blade 420 and the bottom surface of the vessel 310, so that the material to be stirred is pressed against the bottom surface of the vessel 310. This can prevent sticking.

In some embodiments, on a cross section perpendicular to the second axis of rotation, the leading surface 423 of the second blade 420 may have a concave profile, and the trailing surface 421 may have a convex profile. Accordingly, a cross section of the second blade 420 orthogonal to the second axis of rotation may have an approximately S-shape.

In some embodiments, the twist direction of the bottom surface 427 of the second blade 420 relative to the top surface 425 may be opposite to the rotation direction.

11 to 13 are a perspective view, a plan view, and a front view of a first disperser blade 431 according to embodiments of the present disclosure, and FIGS. 14 to 16 are a second disperser blade according to embodiments of the present disclosure. (433) is a perspective view, a plan view, and a front view.

In some embodiments, the third blade may include a first disperser blade 431 and a second disperser blade 433 spaced apart from each other along a third axis of rotation. The first disperser blade 431 and the second disperser blade 433 may have a substantially disk-shaped shape in which a third axis of rotation passes through the center.

In some embodiments, each of the first and second disperser blades 431 and 433 may include a plurality of fins formed along the circumference thereof. The plurality of pins include a plurality of upward protruding pins 431a and 433a protruding from the upper surfaces of the first and second disperser blades 431 and 433, the first disperser blade 431 and the second disperser blade 431. A plurality of downward protruding pins 431b and 433b formed to protrude from the bottom surface of the two disperser blades 433 may be included. The upper protruding pins 431a and 433a and the lower protruding pins 431b and 433b may be alternately formed along the circumferences of the first and second disperser blades 431 and 433 .

By the rotating first blade 410 and the second blade 420, the target material moves left and right, as well as convective movement up and down along the shape of the twisted blade, so that agitation and dispersion are achieved. Here Disperser blades 431 and 433 capable of improving the dispersing function may be additionally installed to further improve the stirring quality.

Since the first blade 410 and the second blade 420 for stirring have a main function of kneading, the kneading function is achieved but the dispersing function is poor, and therefore the first blade 410 and the second blade 420 ) alone, some substances to be stirred can be deposited on the wall and bottom of the container. Therefore, in the embodiments of the present disclosure, kneading and dispersing are simultaneously achieved by adding disperser blades 431 and 433 capable of efficiently achieving a dispersing function, and a portion of the material to be stirred is disposed on the wall and bottom surface of the container. deposition can be prevented.

17 is a layout view of a first blade 410, a second blade 420, and a first disperser blade 431 according to embodiments of the present disclosure.

Circles drawn by the rotation trajectories of the first blade 410 and the second blade 420 may partially overlap. However, by adjusting the orientation of the first blade 410 and the second blade 420, the first blade 410 and the second blade 420 can pass by in close proximity to each other without colliding. . As the first blade 410 and the second blade 420 approach each other, the material to be stirred may be ground between both ends of the first blade 410 and the leading surface 423 of the second blade 420 . As described above, the mixer according to the embodiments of the present disclosure has the advantage of preventing aggregation of the material to be stirred and further enhancing the stirring effect by performing grinding as well as stirring of the material to be stirred. The circle drawn by the rotation trajectory of the third blade may not overlap with the circles drawn by the rotation trajectory of the first blade 410 and the second blade 420 .

As described above, the second blade 420 has a simple plate-like shape without a central through-hole, and enables more efficient stirring by performing a grinding action while stirring the material to be stirred. However, depending on the situation and purpose, such as the type of material to be stirred or the user's choice using the mixer, the second blade 420 has a through hole formed in the center like the first blade 410, and the body is formed only toward the rim. In this case, it may be a design that puts more emphasis on agitation of the substance to be stirred rather than a grinding action.

In an embodiment in which the rotation ratio of the first blade 410 and the second blade 420 is 2:1, the first blade 410 rotates twice and the second blade 420 rotates once while one cycle of rotation is performed. Then, the first blade 410 and the second blade 420 pass through the nearest point twice and perform grinding.

In some embodiments, when the first blade 410 and the second blade 420 rotate, the closest distance between the first blade 410 and the second blade 420 is 3 mm to 8 mm. can be placed.

In some embodiments, the first blade 410 may be arranged so that the nearest distance between the inner wall of the container 310 is 3 mm to 8 mm. With this configuration, the first blade 410 not only performs grinding based on the leading surface 423 of the second blade 420, but also grinds the material to be stirred based on the inner wall of the container 310. Therefore, it is possible to increase the grinding area and the grinding efficiency of the target material.

In some embodiments, the first blade 410 and the second blade 420 may be arranged so that the nearest distance between the bottom surface of the container 310 is 3 mm to 8 mm.

Rotation axes of the first blade 410, the second blade 420 and the third blade may be configured to be eccentric from the center of the container 310.

As the rotation ratio of the first blade 410 and the second blade 420 is configured as 2:1, when the first blade 410 rotates one time, both ends of the first blade 410 are respectively second blades ( 420) Grinding is performed once while passing very close to the leading surface 423. When the second blade 420 is viewed as a standard, when the second blade 420 rotates once, a total of two times of grinding is performed. .

Although described above with reference to the embodiments of the present disclosure, those skilled in the art will be able to variously modify and change the present invention within the scope of the present invention described in the claims described below. Therefore, if the modified implementation basically includes the elements of the claims, all of them should be considered to be included in the technical scope of the present invention.
