[0006] Preferably, the sealing rings are provided at the lower parts of the inner walls on both sides of the inner groove, and the two sealing rings are respectively connected to independent air pumps.

[0007] Preferably, the sealing ring is embedded in the side wall of the inner groove, and the sealing ring expands outward from the side wall of the inner groove when inflated.

[0008] Preferably, the expansion of the sealing ring will compress the glass cover in two directions.

[0009] Preferably, the inner ring is inserted into an inner groove outside the glass cover.

[0010] Preferably, the sealing ring is a rubber sealing ring, and the bottom ring is a rubber ring.

[0011] Beneficial effect: In the utility model, an additional sealing measure is provided at the opening of the cold trap, and the glass cover is firmly sealed on the cold trap by utilizing the cooperation of the inner groove, the outer groove and the sealing ring. A sealing ring is also provided at the lower part of the inner groove. The sealing ring can expand and fill the inner ring after the glass cover is placed, and the inner ring is pressed on the expanded sealing ring to achieve better sealing.

[0015] Figure 4 Shows Figure 3 A partial enlarged view of middle A. DETAILED DESCRIPTION

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] like Figure 1~Figure 4 An energy-saving and environmentally friendly vacuum freeze dryer is shown, in which a cold trap 2 is installed in the middle of a machine body 1, a display screen 6 and a control panel 7 are arranged on the front side thereof, a sealing groove 4 is arranged on the outer side of the opening of the cold trap 2, and the sealing groove 4 is double-layered, which is divided into an inner groove 41 and an outer groove 42. A glass cover 3 is inserted into the inner groove 41, and the inner wall of the glass cover 3 will be tightly attached to the inner wall of the inner groove 41. An inner ring 9 and an outer ring 8 are arranged on the lower side of a sealing ring 5, and the inner ring 9 is inserted into the inner groove 41. The inner ring 9 is located on the outer side of the glass cover 3, and the glass cover 3 will be sealed from the outside. The outer ring 8 is inserted into the outer groove 42, and the outer ring 8 serves as an outer sealing strip.
