Therefore, in the prior art, a crushed ice machine is often used to crush the ice cubes into a slush or ice slurry. A stirring device is often arranged in the crushed ice machine, and stirring blades are arranged on the stirring device. The stirring blades generate a force with the ice cubes in the rotating process to crush the ice cubes into slush.

[0004] However, in the stirring blades of the existing stirring device, in order to ensure that the ice cubes have sufficient accommodation space, the radial width of the blades is too short. Moreover, the stirring blades are mostly spiral-shaped, so the blades are too smooth and the blade spacing in the axial direction is too large, which results in a lack of sufficient grabbing and cutting capacity of the blades. As a result, the ice cubes can freely rotate at the gap of the blades, which causes the ice cubes to finally form large ice blocks that float to the top of the stirring device and rotate with the stirring blades, and slush cannot be formed.

It should be noted that in this embodiment, the projection of the third blade 5 on the central axis does not overlap the first blade 3, avoiding interference between the third blade 5 and the second blade 4. In this embodiment, the third blade 5 is relatively fixedly connected with the stirring barrel 1 through the top cover 8, thereby ensuring that the third blade 5 has the characteristic of not moving relative to the rotating first stirring group, so that the first stirring group can rotate relative to the third blade 5, thereby ensuring the effectiveness of cutting the ice blocks. Moreover, the third blade 5 is closer to the mounting bracket 2, which can cut the ice blocks close to the mounting bracket 2, thereby avoiding the ice mud from being attached to the outer surface of the mounting bracket 2 and rotating together with the mounting bracket 2, greatly ensuring the cutting effectiveness of the ice blocks at the upper end portion of the stirring barrel 1, and improving the efficiency of forming the snow ice.

[0052] In another optional embodiment of the present application, the third blade 5 and the second blade 4 are distributed along the same circumferential interval, that is, the third blade 5 and the second blade 4 are not arranged in the same radial direction, but are arranged in a circumferential direction. It is only necessary to ensure that there is a radial gap between the third blade 5 and the second blade 4 and the outer surface of the mounting bracket 2, which can allow the liquid to flow. It should be noted that in this embodiment, the projection of the third blade 5 on the central axis does not overlap the first blade 3, avoiding interference between the third blade 5 and the second blade 4.

[0053] In another optional embodiment of the present application, the third blade 5 and the second blade 4 are distributed along different circumferences, and the third blade 5 can be arranged to be longer. In the projection on the central axis, the third blade 5 can overlap the first blade 3, that is, the length of the third blade 5 can extend to the lower end portion, as long as there is a gap between the third blade 5 and the first blade 3, the second blade 4 and the mounting bracket 2, that is, the radial distance between the third blade 5 and the central axis is greater than the distance between the first blade 3 and the central axis and the distance between the second blade 4 and the central axis, thereby avoiding interference between the first stirring group and the third blade 5 when the first stirring group rotates.

[0054] On the basis of any of the above embodiments, the third blade 5 is further described. Specifically, as shown in FIG. 4, the third blade 5 is arranged in the same radial direction as the second blade 4, that is, in the radial direction, the third blade 5 is located in the radial gap between the mounting bracket 2 and the second blade 4, and there is a gap between the third blade 5 and the second blade 4 and the mounting bracket 2, that is, the third blade 5 does not contact the mounting bracket 2 and the second blade 4, so as to ensure the smooth rotation of the first stirring group. The radial distance between the third blade 5 and the mounting bracket 2 is smaller than the radial distance between the third blade 5 and the second blade 4, and there is an axial gap between the bottom of the third blade 5 and the second blade 4. It should be noted that in this embodiment, the projection of the third blade 5 on the central axis does not overlap the first blade 3, avoiding interference between the third blade 5 and the second blade 4. Figure 2 , Figure 3As shown, the third blade 5 is an L-shaped structure, which comprises an axial extension 51 and a radial extension 52, the axial extension 51 is perpendicularly connected with the radial extension 52, and both the axial extension 51 and the radial extension 52 are plate-shaped structures; wherein the radial extension 52 is connected with the top cover 8, and the projection of the axial extension 51 on the central axis at least partially overlaps with the second blade 4, so that the axial extension 51 has sufficient length to ensure the area in contact with the ice block to effectively cut the ice block.

[0055] It should be noted that in the present application, the arrangement between the third blade 5 and the second blade 4 and the first blade 3 can be set as a symmetrical structure, or as an asymmetrical structure; the number of the first blade 3, the second blade 4 and the third blade 5 can be selected according to actual needs.

[0056] As shown in Figure 3 , Figure 4 , the top cover 8 is provided with a limiting step 81 and a mounting port 82, the limiting step 81 is located radially outside the mounting port 82, the mounting port 82 penetrates the top cover 8 along the axial direction, the size of the mounting port 82 is adapted to the size of the axial extension 51 of the third blade 5, the mounting port 82 is used for the axial extension 51 to pass through, and the limiting step 81 has a radially extending limiting surface, and the radial extension 52 acts on the limiting step 81 to axially limit the radial extension 52; thereby enabling the third blade 5 to be relatively stably connected to the top cover 8.

[0057] Further, as shown in Figure 4 , the limiting step 81 is provided with a limiting groove, and the radial extension 52 is provided with a limiting port, the limiting port and the limiting groove are coaxially arranged to be inserted by the same connecting piece, thereby enabling the limiting step 81 and the radial extension 52 to be tightly connected, to ensure the stability and firmness of the connection between the third blade 5 and the top cover 8, so that the third blade 5 can be relatively stable when impacted by the ice block and will not easily shake.

[0058] In the present embodiment, the connecting piece is preferably a screw.

[0059] Further, as shown in Figure 3 , Figure 4 , the top cover 8 is provided with a first auxiliary blade 83, the first auxiliary blade 83 is arranged at a circumferential interval from the third blade 5, and the first auxiliary blade 83 extends along the axial direction towards the first stirring group, i.e. the first auxiliary blade 83 extends downward beyond the bottom of the top cover 8, the axial length of the first auxiliary blade 83 is less than that of the third blade 5, and the first auxiliary blade 83 can cut the top of the ice block floating to the end of the top cover 8 to assist in the production of the slush ice.

[0060] Further, as shown in Figure 6As shown, the stirring barrel 1 is provided with a discharge base 12 away from one end of the top cover 8, the discharge base 12 seals the bottom of the stirring barrel 1, and is provided with a discharge port, so that the processed liquid can flow out of the discharge port for the user to use. Figures 1 to 2 As shown, the discharge base 12 is provided with a second auxiliary blade extending axially towards the direction of the top cover 8, that is, the bottom of the stirring barrel 1 is provided with a second auxiliary blade extending upwards, and the second auxiliary blade rotates relative to the first stirring group, wherein the second auxiliary blade has a radial gap with the inner wall of the stirring barrel 1 and the first stirring group, which can avoid interference with the first stirring group and provide space for accommodating ice blocks to cut the ice blocks at the bottom of the stirring barrel 1.

[0061] Under the action of the first auxiliary blade 83 and the second auxiliary blade, the ice blocks at the top and bottom of the stirring barrel 1 can be cut, thereby ensuring the overall cutting of the ice blocks at each position in the stirring barrel 1, reducing the probability of ice mud clumping and the first stirring group moving, and ensuring the formation efficiency of the snow ice.
