It should be noted that the ice taking device 200 can automatically deliver the ice cubes made by the ice making device 100 to the outside, the storage barrel 210 of the ice taking device 200 can store the ice cubes made by the ice making device 100 continuously, the main control system 500 can drive the delivery screw 230 to rotate when a user needs to take the ice cubes, so as to deliver the ice cubes in the storage cavity 211 of the storage barrel 210 to the outside, and the ice cubes can enter the user's vessel through the ice outlet 212 and the chute 221 of the ice outlet hopper 220 in sequence. In addition, here, in order to prevent the ice cubes in the storage cavity 211 of the storage cylinder 210 from melting, an insulating cylinder 250 may be coaxially disposed at the periphery of the storage cylinder 210, and the external heat is insulated from the ice cubes in the storage cavity 211 of the storage cylinder 210 by the insulating cylinder.

As a preferred embodiment, as shown in fig. 12 and 13, an ice discharging part 213 may be provided on the storage tube 210 such that the conveying screw 230 conveys the ice cubes outward along the ice discharging part 213. Specifically, the storage barrel 210 comprises a bottom wall 214 arranged at the periphery of the ice making barrel 120 and a side wall 215 enclosed on the bottom wall 214, an ice outlet 213 on the storage barrel 210 is recessed downwards from the bottom wall 214 and extends towards the direction close to the side wall 215, an ice outlet hole 212 is arranged at the extending end of the ice outlet 213, the ice outlet 213 is arranged obliquely relative to the bottom wall 214, and the recessed depth of the ice outlet 213 is gradually increased towards the direction close to the central axis S of the ice making barrel 120; the other end of the conveying screw 230 extends to the ice discharge portion 213 in a direction close to the bottom of the ice discharge portion 213.

When the conveying screw 230 rotates, the ice cubes at the ice outlet 213 are conveyed outwards by the conveying screw 230, the ice outlet 213 is inclined relative to the bottom wall 214, and the recess depth of the ice outlet 213 closest to the central axis S of the ice making barrel 120 is the largest, so that even if the ice cubes melt at the ice outlet 213, the melted liquid can be deposited at the bottom of the ice outlet 213 and cannot be taken out of the storage barrel 210 along with the movement of the ice cubes, and a user is ensured not to take the ice cubes containing the liquid in the process of taking the ice cubes. In order to discharge the liquid deposited on the bottom of the ice discharging part 213, an opening may be formed on the bottom of the ice discharging part 213 and a pipe may be connected to discharge the liquid deposited on the bottom of the ice discharging part 213.

The ice cubes at the ice outlet 213 are continuously reduced after being transferred to the outside of the ice outlet 212, and other ice cubes in the storage cavity 211 of the storage tube 210 are still accumulated in the storage cavity 211, so that the ice cubes sliding out of the ice outlet 212 of the ice outlet 213 may be interrupted, and it is inconvenient for the ice cubes to be continuously transferred to the outside of the ice outlet 212 of the ice outlet 213. Therefore, in a specific embodiment, a stirring rod 161 (shown in fig. 5) may be disposed in the storage cavity 211 of the storage barrel 210, the stirring rod 161 may be disposed on the break-off cap 160, the break-off cap 160 may be driven when the extrusion screw 130 rotates, so as to drive the stirring rod 161 on the break-off cap 160, and the stirring rod 161 may stir ice cubes in the storage cavity 211 of the storage barrel 210 during the rotation, so that the ice cubes accumulated in the storage cavity 211 may move to the ice outlet 213, so as to achieve continuous ice discharge. The stirring rod 161 can be multiple, each stirring rod 161 extends towards the direction close to the side wall 215 along the bottom wall 214 of the storage cylinder 210 and bends and extends towards the direction far away from the bottom at the end extending to the side wall 215, so as to form an L-shaped stirring rod 161, and through the stirring action of the stirring rod 161 in the storage cavity 211 of the storage cylinder 210, not only can the accumulation of ice cubes in the storage cavity 211 be avoided, but also the adhesion phenomenon of the ice cubes in the storage cavity 211 can be prevented.

In addition, in order to prevent the ice cubes from slipping out of the ice outlet hole 212 when the rotation of the conveyor screw 230 is stopped, a spill prevention member 260 (shown in fig. 10 and 11) may be disposed at the ice outlet hole 212, the spill prevention member 260 may include a connection portion 261 and a plurality of protrusions 262 spaced apart from each other, the connection portion 261 may be connected to the ice outlet portion 213, the plurality of protrusions 262 may extend from the connection portion 261 in a direction toward a central axis Y (shown in fig. 11 and 12) of the ice outlet hole 212, each protrusion 262 may be made of a flexible material, and the flexible material may be silicone rubber harmless to a human body. Thus, when the conveying screw 230 stops rotating, the protrusion 262 will block the ice outlet 212 to block the ice cubes, so as to prevent a part of the ice cubes from sliding out of the ice outlet 212 under the extrusion of other ice cubes, and when the conveying screw 230 rotates, the protrusion 262 pressed by the conveying screw 230 will bend, and the ice cubes will still slide out of the ice outlet 212 under the driving of the conveying screw 230, so that the normal ice taking of a user is not affected.

It should be noted that the shape of the protruding portion 262 shown in fig. 10 and 11 is a triangle, wherein the sharp corner at one end of the protruding portion 262 is disposed toward the central axis Y of the ice outlet 212, and the shape of the protruding portion 262 can be other types, such as a rectangle or a square, which can achieve the purpose of blocking the ice cubes from sliding out of the ice outlet 212 when the conveying screw 230 stops rotating. The connecting portion 261 and the plurality of protrusions 262 may be integrally formed, so as to facilitate the fabrication of the spill prevention member 260.
