The ice-fixing blade 22 includes a plurality of rib plates axially spaced along the blade shaft 61, and the plurality of rib plates are formed on opposite sides of the ice-crushing cavity 21, that is, each side is formed with a plurality of rib plates, where the two sides refer to two sides along the rotation direction of the blade shaft 61, and the direction along the blade shaft 61 can be considered as front and rear sides of the ice-crushing device. The movable blade 62 includes a plurality of movable blades 63 disposed on the arbor 61 at intervals, and each movable blade 63 is axially located between two rib plates on each side along the arbor 61. Specifically, the plurality of rib plates include a first rib plate 221 disposed on one side of the ice crushing cavity 21 and a second rib plate 222 disposed on the opposite side of the ice crushing cavity 21, the first rib plate 221 and the second rib plate 222 may be disposed in a one-to-one correspondence manner, each first rib plate 221 has a first plate surface 225 facing an adjacent first rib plate, here, adjacent refers to adjacent along the axial direction of the ice blade shaft 61, the first plate surface 225 may be disposed in a plane, a curved surface, a wavy surface, an inclined surface, an arc surface, etc., the first plate surface 225 is provided with a plurality of convex teeth disposed at intervals, a distance between each movable blade 63 and the convex teeth is smaller than a distance between each movable blade 63 and a plate surface of the second rib plate 222, a first ice crushing area is formed between two adjacent first plate surfaces 225, and a second ice crushing area is formed between two adjacent second rib plates 222, and the ice blade shaft 61 can drive the movable blades 63 to rotate along different directions through the first ice crushing area and the second ice crushing area, so as to realize different ice specifications output from the ice crushing cavity 21 into the ice storage cavity 31.

In this embodiment, 5 moving blades 63 are preferably arranged, and 45 degrees of spacing are arranged between every two moving blades 63, so that progressive ice crushing is realized, ice crushing torque, ice crushing noise and ice crushing noise can be effectively reduced, and user experience is improved.

That is, the upper end of the second rib plate 222 is higher than the upper end of the first rib plate 221, when the ice is crushed, the ice covered by the upper end of the first rib plate 221 is thicker, and the ice jumping resistance is larger, so that the ice jumping is not easy to occur, the noise during the ice crushing is reduced, and the user experience is improved.
