[0029] The stirring device in the existing production and life has a part of complex structure and large space occupation, and is only suitable for specific occasions; the other part of structure is relatively simple, but basically needs to change the stirring position flexibly to realize the purpose of uniform stirring, and needs additional external force support.
[0030] Therefore, the utility model provides a curved blade type stirring head, which is formed by the cooperation of the upper curved edge 31, the lower curved edge 32 and the sharp corner 33, and the curved blade 30 is curved in the horizontal space and the vertical space, which is beneficial to improve the mixing uniformity of the stirred materials, and is especially suitable for the mixing work of paint liquid.
[0031] Specifically, in the embodiment, the connecting shaft 10 is connected with the curved blade 30 for stirring to realize the specific stirring work, the plurality of curved blades 30 are uniformly and circularly distributed around the body 20 to form a stirring impeller, so that the stirring is realized.
[0032] The stirring head is usually arranged at a position below the stirring container, and forms a vortex during stirring to drive the mixing of the liquid from bottom to top, so that the stirring work is facilitated. The sharp corner 33 is located on the plane where the bottom of the curved blade 30 is located, which is beneficial to fully stir the materials at the bottom of the stirring container, and avoids the phenomenon of uneven stirring caused by the stirring dead angle.
[0033] Preferably, the curved blade 30 comprises the upper curved edge 31 and the lower curved edge 32, the upper curved edge 31 and the lower curved edge 32 are respectively curved and extended to intersect to form the above-mentioned sharp corner 33, and the sharp corner 33 is arranged close to the lower curved edge 32.
[0034] Here, preferably, the curved blade 30 is enclosed by the upper curved edge 31 and the lower curved edge 32, and the sharp corner 33 is formed by the intersection of the upper curved edge 31 and the lower curved edge 32 at the end away from the body 20, preferably, the sharp corner 33 is arranged close to the lower curved edge 32, further, the bottom of the sharp corner 33 is flush with the bottom of the lower curved edge 32, and the bottom of each curved blade 30 (lower curved edge 32) is located on the same plane, so that the overall stability of the stirring head is good, and it can be erected on a horizontal plane when not in use, facilitating storage.
[0035] Further, the distance between the upper curved edge 31 and the lower curved edge 32 gradually increases first and then gradually decreases from the end close to the body 20 to the end away from the body 20, until the upper curved edge 31 and the lower curved edge 32 intersect, and the length of the upper curved edge 31 is greater than the length of the lower curved edge 32.
[0036] The curved blade 30 is enclosed by the upper curved edge 31 and the lower curved edge 32, if the curved blade 30 is cut along multiple vertical planes, the area of each section of the curved blade 30 changes with the distance between the upper curved edge 31 and the lower curved edge 32.
[0037] In view of the distance between the upper curved edge 31 and the lower curved edge 32 gradually increasing first and then gradually decreasing from the end close to the body 20 to the end away from the body 20 until the upper curved edge 31 and the lower curved edge 32 intersect, the area of the middle part of the curved blade 30 is greater than the area of the two ends, the increase of the area of the middle part of the curved blade 30 is beneficial to enhance the stirring effect on the mixed liquid, and facilitate uniform mixing of the liquid;
[0038] The area of the curved blade 30 close to the sharp corner 33 decreases, which is beneficial to the outward extension of the curved blade 30, the sharp corner 33 can break through the resistance of the liquid on one hand, and stir the liquid at other positions away from the center position of the connecting shaft 10, on the other hand, the outward extension of the sharp corner 33 increases the stirring range to a certain extent, avoids the occurrence of stirring dead angle, and further enhances the stirring effect.
