State in seal groove.
As the further improvement of above-mentioned technical proposal：
The body includes L-shaped transverse part and vertical part, and the seal groove includes can horizontal stroke corresponding with the transverse part, vertical part
Groove, vertical slot, the second seal with first seal against when fitted with the vertical part.
The translot is set to oat tail groove structure.
The cleaning apparatus have door opening and door body, and the door opening is correspondingly provided with doorframe, and the first seal is described
Doorframe, the second seal is the door body.
The vertical slot is square, and is set near the door opening.
The compression dead slot is located at body middle part, bottom wall of the opening for compressing dead slot towards the seal groove.
Compared with prior art, the utility model has the advantage of：
（1）Sealing structure for cleaning apparatus of the present utility model, protrudes when sealing ring is extruded by second seal
Portion moves to body, and compression dead slot shrinks, and protuberance can easily clamp-on sealing ring, and good sealing effect is empty by setting compression
Groove ensures that sealing ring can produce larger deformation quantity when by smaller pretightning force, and first seal, second seal it
Between can be very good sealing, be therebetween not in deformation post gap of the prior art.
（2）Sealing structure for cleaning apparatus of the present utility model, the door of the body of freeze dryer that seal groove can be set
Be not in deformation post gap of the prior art on frame or on chamber door, between chamber door and doorframe, in the absence of cleaning dead band
In the presence of, and noresidue water retains area, meets GMP requirements.
（3）Sealing structure for cleaning apparatus of the present utility model, seal groove is set to L-type, the vertical part of sealing ring with
The vertical slot of seal groove offsets so that without cleaning dead band between chamber door and doorframe.

Specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
Fig. 4 to Fig. 7 shows the utility model for a kind of embodiment of the sealing structure of cleaning apparatus, and this is used for cleaning
The sealing structure of equipment includes first seal 1, second seal 2, sealing ring 3 and seal groove 4, and it is close that seal groove 4 is located at first
On sealing 1, sealing ring 3 includes body 31 and the protuberance 32 that is connected with body 31, body 31 in a free state with seal groove 4
Coordinate, protuberance 32 is located at outside seal groove 4 in a free state, body 31 is provided with compression dead slot 5, protuberance 32 towards second is close
