DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model.

[0021] Please refer to Figures 1-5 , the door body for the refrigerator in the embodiment, including door body 1, door body 1 is provided with air pressure balance chamber 2, air pressure balance chamber 2 is equipped with through hole one 201 and through hole two 202, through hole one 201 is connected with the inside of the refrigerator and air pressure balance chamber 2, through hole two 202 is connected with the inside of air pressure balance chamber 2 and the outside of the refrigerator, air pressure balance chamber 2 is equipped with sliding piece 3, both sides of sliding piece 3 are equipped with sealing assembly, sealing assembly includes the sealing section 301 of being set at both ends of sliding piece 3 and the sealing piece 4 corresponding with sealing section 301, sealing section 301 and sealing piece 4 are equipped with magnetic layer, and magnetic is different, sealing piece 4 is fixedly set in the inner wall of air pressure balance chamber 2, and is equipped with through hole inside, one of sealing piece 4 is located the periphery of through hole one 201, and the magnetism is less than another sealing piece 4.

[0022] In the application, the device is provided with a magnetic layer in the sealing section 301 and the sealing piece 4, which can freely open or close the connecting channel between the inside of the refrigerator and the inside of the air pressure balance chamber 2.

[0023] When the refrigerator door is closed, the sealing piece 4 on one side of the through hole one 201 is magnetically attracted to the sealing section 301, so that the connecting channel between the inside of the refrigerator and the inside of the air pressure balance chamber 2 is closed.

[0024] When the refrigerator door needs to be opened, the sliding piece 3 is moved away from the through hole one 201, and because the magnetic of the sealing piece 4 located at the periphery of the through hole one 201 is less than that of the other sealing piece 4, under the action of magnetic attraction and thrust, the sliding piece 3 can be quickly moved to the other side.

[0025] Because the connecting channel between the inside of the refrigerator and the inside of the air pressure balance chamber 2 is opened, and the channel connecting the inside of the air pressure balance chamber 2 and the outside of the refrigerator is always kept open, the pressure inside the refrigerator and the outside can gradually balance. At this time, the refrigerator door is opened, and the user can easily open the door body.

[0026] Further, the sliding piece 3 is provided with a poking piece 5, the poking piece 5 is provided with a plurality of through holes, the air pressure balance chamber 2 is provided with a sliding groove 203, the poking piece 5 is located in the sliding groove 203 and is in sliding connection with the sliding groove 203, and the through hole two 202 is located in the sliding groove 203.
