 a one-way valve, disposed on the partition wall and configured to allow only the air in the area where the drawable box is located to flow toward the accommodating cavity; and   a vacuum pump, transversely disposed inside the accommodating cavity and connected to one side of the one-way valve located in the accommodating cavity by an air exhausting pipe.   
     
     
         6 . The refrigerator provided with a sealed drawer on a door body according to  claim 4 , wherein the ventilating device comprises:
 a ventilation valve, disposed on a wall of the accommodating cavity toward the first storage space; and   a ventilation pipe, extending from the ventilating valve to the partition wall and in communication with the area where the drawable box is located.   
     
     
         7 . The refrigerator provided with a sealed drawer on a door body according to  claim 3 , further comprising:
 a second door, pivotally disposed on one side of the first door away from the refrigerator body; and   a door opening and closing detector, configured to sense an open/close state of the first 
 door and the second door; and 
 the air exhausting device is further configured to be turned on only when the first door and the second door are both closed. 
 
     
     
         8 . The refrigerator provided with a sealed drawer on a door body according to  claim 1 , further comprising:
 a sealing element, disposed at a position where a panel of the drawable box faces the sealed barrel, wherein the sealing element is extruded by the panel of the drawable box and the sealed barrel when the drawable box is closed, so as to seal a gap between the panel of the drawable box and the sealed barrel.   
     
     
         9 . The refrigerator provided with a sealed drawer on a door body according to  claim 8 , further comprising:
 a locking element, configured to limit the positions of the panel of the drawable box and the sealed barrel when the drawable box is closed, and comprising:   limiting posts, extending from front ends disposed at two sides of the sealed barrel toward the panel of the drawable box; and   limiting grooves, formed on two sides of the panel of the drawable box and configured to cooperate with the limiting posts to lock the position of the drawable box.   
     
     
         10 . The refrigerator provided with a sealed drawer on a door body according to  claim 8 , wherein the drawable box further comprises:
 a pivoting handle, comprising:
 two pivoting arms, with one ends pivotally connected to two sides of a front panel of the drawable box within a set rotating angle, respectively; and 
 pull rods, connected to the other ends of the two pivoting arms and configured to be held by a user to apply a force for pulling the drawable box after the pivoting arms rotate to a set angle. 
   
     
     
         11 . The refrigerator provided with a sealed drawer on a door body according to  claim 9 , wherein the drawable box further comprises:
