[0002] The freezer door is one of the external structures of a freezer, mainly used to seal the interior of the freezer, ensuring that cold air does not leak out and thus maintaining the low temperature environment inside. To ensure that the freezer door has good sealing and heat insulation performance, so as to reduce cold loss and ensure the freshness and freezing effect of food, a door seal is usually installed on the contact surface between the freezer door and the cabinet body.

[0003] Refrigerator door seals are accessories used to seal the refrigerator door and cabinet. They are made of elastic materials and have a U-shaped design. They are usually equipped with an airbag structure to reduce heat exchange. Traditional door seals are usually glued to the inside of the refrigerator door rails. However, after long-term use, dirt can easily accumulate inside the door seal, which can not only lead to a decrease in sealing performance, but also contaminate the food inside the cabinet. Summary of the Invention
