[0046] In this application, the first driving member 131 and the door sealing strip 132 perfect the structure of the first sealing assembly 13, improve the water sealing performance of the first sealing assembly 13, and make the door sealing strip 132 inflatable or recoverable, thereby improving the flexibility of the door sealing strip 132.

[0047] In one embodiment, referring to FIGS. 1 and 2, the door sealing strip 132 comprises a first connecting member 1321, a bubble tube 1322 and a water absorbing member 1323 connected together. The first connecting member 1321 is adapted to be connected to the door 11. The bubble tube 1322 is adapted to be connected to the door frame 12. The bubble tube 1322 encloses a receiving cavity, which communicates with the first driving member 131 and accommodates the water absorbing member 1323. The water absorbing member 1323 has an inflatable structure when it comes into contact with water.

[0048] Exemplarily, the shape of the cross section of the accommodating cavity is any one of a polygon, an ellipse, a circle, and an irregular shape. For example, the shape of the cross section of the accommodating cavity can specifically be, but is not limited to, a quadrilateral, a hexagon, an octagon, an ellipse, a circle, and an irregular shape, etc.

[0049] Exemplarily, the shape of the cross section of the bubble tube 1322 is in the shape of a circular arc.

[0050] Exemplarily, the water-absorbing member 1323 is a superabsorbent polymer.
