Further, in this embodiment, the vacuum chamber 4 surrounds the ice outlet 11 for a circle, which is a continuous groove structure around the ice outlet 11 for a circle, the sealing portion 5 is disposed at a periphery of the cover plate 2 and is adapted to the shape of the vacuum chamber 4, the absorption force between the sealing portion 5 and the vacuum chamber 4 is more uniform, and the absorption force is larger, so that the cover plate 2 is more closely absorbed on the ice outlet 11.

When the driving part drives the cover plate 2 to move, the sealing part 5 is driven to move together, after the sealing part 5 covers the opening 43, the negative pressure generator discharges the gas in the vacuum cavity 4, so that the sealing part 5 is in a negative pressure state, and the negative pressure state is always maintained before the cover plate 2 needs to be opened next time, wherein the negative pressure state refers to a corresponding state in which the difference between the internal pressure and the external pressure needs to be overcome when the sealing part 5 is separated from the vacuum cavity 4. When the material of the sealing part 5 is hard, the deformation of the sealing part 5 is less, the gas pressure in the vacuum cavity 4 is less than the atmospheric pressure outside the vacuum cavity 4, and if the sealing part 5 leaves the vacuum cavity 4, the internal and external gas pressure difference needs to be overcome, and the sealing part is attached to the vacuum cavity 4 under the action of the gas pressure difference; extremely, the vacuum cavity 4 can be vacuumized, the air pressure difference between the inside and the outside is maximum, and the sealing part 5 is attached most tightly; 2. when the material of the sealing part 5 is soft, the internal and external air pressure differences can be equal under extreme conditions, the material of the sealing part 5 is greatly deformed, and if the sealing part 5 is separated from the vacuum cavity 4, the deformation is recovered to cause the internal and external air pressure differences, so that the cover plate 2 can be opened only by overcoming the internal and external air pressure differences.
Specifically, the above-described two-material seal portion 5 is discussed in detail:
1. when the material of the sealing part 5 is hard, the sealing part 5 comprises a sealing ring, a sealing gasket is arranged in the sealing ring, when the cover plate 2 moves from an opening state to a closing state, the sealing gasket covers the opening 43, and the sealing ring is abutted against the opening 43; the sealing ring may be made of a material having high rigidity, and the sealing gasket prevents a gap from being formed between the sealing ring and the opening 43, thereby increasing the sealing ability of the sealing ring.
When the cover plate 2 is driven by the driving part to seal the ice outlet 11, the opening 43 is sealed by the sealing ring, the force for sealing the opening 43 depends on the driving force of the driving part, after the ice outlet 11 is sealed by the cover plate 2, the negative pressure generator vacuumizes the vacuum cavity 4, partial gas can be pumped out, the air pressure in the vacuum cavity 4 is lower than the external air pressure, and all gas can be pumped out, so that the vacuum cavity 4 is in a complete vacuum state, and the specific amount of the pumped gas can be formulated according to actual requirements.
2. The sealing portion 5 comprises a sealing skirt surrounding the cover plate 2 for one circumference when the material of the sealing portion 5 is soft, the sealing skirt covering the opening 43 when the cover plate 2 is moved from the open position to the closed position, and the sealing portion 5 may be a silicone material or other material with elasticity covering the cover plate 2 as shown in fig. 2 or 3.

In addition, the sealing skirt can be a single-side structure, the single-side sealing skirt is respectively attached to all edges of the opening 43, and when the cover plate 2 is thick and does not have too much space to leave a first side and a second side, the opening 43 of the vacuum cavity 4 can be covered by the single-side sealing skirt.
Because the material of the sealing skirt is soft, after the negative pressure generator extracts at least part of the gas in the vacuum cavity 4, the sealing skirt is extruded by the vacuum cavity 4 to deform, the amount of the gas extracted by the negative pressure generator is controlled so that the deformation of the sealing part 5 is not too large to cause failure, when the deformation is stopped, the state of the sealing part 5 at this time is set to be a negative pressure state, when the sealing part 5 is in the negative pressure state, the air pressure in the vacuum cavity 4 can be smaller than or equal to the external air pressure, at this time, if the cover plate 2 needs to be opened, the sealing part 5 is far away from the vacuum cavity 4, but when the sealing skirt is far away, the extruded deformation needs to be recovered first, the volume of the space enclosed by the sealing part 5 and the vacuum cavity 4 is increased in the recovery process, the internal pressure is reduced and is smaller than the external pressure, the difference between the internal pressure and, when the sealing portion 5 has a tendency to be away from the vacuum chamber 4, the negative pressure state of (2) is resisted by the difference between the internal pressure and the external pressure, so that the sealing degree between the cover plate 2 and the ice outlet 11 is more firm.
