[0040] ​The sealing assembly 10 comprises a support frame 101 which is connected to the drying bin 2 by bolts, the support frame 101 is provided with a guide groove, the upper part of the guide groove of the support frame 101 is arranged in a slope direction, the support frame 101 is provided with a hydraulic rod 102 which is connected by bolts, the support frame 101 is provided with a sealing cover 103 which is connected in a sliding mode in the guide groove, the sealing cover 103 is used for sealing the drying bin, the guide groove of the support frame 101 is arranged in a slope direction and is used for rotating the sealing cover 103, the sealing cover 103 is provided with a straight groove, the top of the sealing cover 103 is provided with a valve, the valve of the sealing cover 103 is used for balancing the internal and external air pressure of the drying bin 2, and the straight groove of the sealing cover 103 is connected in a sliding mode with the telescopic rod of the hydraulic rod 102.

[0041] The vacuum mechanism 11 comprises a guide disc 111 which is connected to the rotating ring 4 through a key groove, the bottom of the guide disc 111 is provided with an annular groove, two piston pipes 112 are connected between the support column 3 and the base 1 by bolts, the piston pipe 112 is provided with a cavity, the bottom of the piston pipe 112 is provided with a through hole, the through hole of the piston pipe 112 is communicated with the cavity of the piston pipe 112, the through hole of the two piston pipes 112 is provided with a second one-way valve 115, the two piston pipes 112 are provided with a piston rod 113 which is connected in a sliding mode, the two piston rods 113 are hollow structures, the top of the two piston rods 113 is connected in a sliding mode with the annular groove of the guide disc 111, the guide disc 111 drives the two piston rods 113 to move back and forth through the annular groove at the bottom, and the two piston rods 113 are provided with a first one-way valve 114.

[0042] At the beginning, the telescopic rod of the hydraulic rod 102 is resisted by the straight slot of the sealing cover 103, so that the sealing cover 103 is in an open state. First, the operator connects the conductive slip ring 81 with the power supply, and then turns on the power supply. The power supply will be transmitted to the six electric heating rods 82 through the conductive slip ring 81, so that the heating end of the six electric heating rods 82 starts to heat. Then the operator puts the plated vacuum flask 7 into the rotating frame 6 respectively. The rotating frame 6 is in contact with the vacuum flask 7 through the rubber bushing, thereby buffering the vacuum flask 7. After the vacuum flask 7 is put into the rotating frame 6, the heating end of the electric heating rod 82 will penetrate into the vacuum interface of the vacuum flask 7. Because the plating layer in the vacuum sandwich layer of the vacuum flask 7 can isolate most of the external heat, the vacuum sandwich layer of the vacuum flask 7 is heated through the vacuum interface of the vacuum flask 7 by the electric heating rod 82, so that the water in the vacuum sandwich layer of the vacuum flask 7 is more easily evaporated, thereby drying the vacuum flask 7. Then the operator controls the telescopic rod of the hydraulic rod 102 to retract. The retraction of the telescopic rod of the hydraulic rod 102 will drive the sealing cover 103 to move downward through the straight slot of the sealing cover 103, and at the same time the sealing cover 103 will rotate through the guide slot of the supporting frame 101, so that the sealing cover 103 is parallel to the drying chamber 2. The sealing cover 103 continues to move downward driven by the hydraulic rod 102 to close. After closing, the edge of the sealing cover 103 and the drying chamber 2 will engage with each other, thereby improving the sealing performance of the drying chamber 2. Because the water droplets evaporated are easy to leave mineral crystals, the operator starts the servo motor 91. The rotation of the output shaft of the servo motor 91 drives the first gear 92 to rotate. The rotation of the first gear 92 drives the rotating ring 4 to rotate through the rotation of the second gear 93, so that the rotating ring 4 drives the six rotating frames 6 and the six vacuum flasks 7 to rotate through the six supporting arms 5, thereby throwing out the water droplets in the vacuum flask 7, so that the moisture is not easy to leave mineral crystals in the vacuum sandwich layer of the vacuum flask 7, thereby enhancing the drying effect of the vacuum flask 7. The rotating ring 4 rotates at the same time to drive the guide disc 111 to rotate. The rotation of the guide disc 111 will extrude the two piston rods 113 to reciprocate in the two piston tubes 112 through the annular groove. When the piston rod 113 moves towards the piston tube 112, the piston rod 113 will extrude the air in the cavity of the piston tube 112, so that the air in the cavity of the piston tube 112 is discharged to the outside of the drying chamber 2 through the second one-way valve 115 and the channel of the base 1. When the piston rod 113 moves away from the piston tube 112, the cavity of the piston tube 112 generates negative pressure, so that the air in the drying chamber 2 enters the piston tube 112 through the first one-way valve 114 and the hollow structure of the piston rod 113. In this way, the air in the drying chamber 2 is gradually discharged through the reciprocating movement of the piston rod 113, thereby reducing the air pressure in the drying chamber 2, so that the boiling point of the moisture in the vacuum flask 7 is lowered and more easily evaporated, thereby further enhancing the drying effect of the vacuum flask 7.After the thermos flask 7 is dried, the operator closes the electric heating rod 82 so that the electric heating rod 82 no longer generates heat, then the operator closes the servo motor 91 so that the rotating ring 4 no longer drives the six rotating frames 6 and the six thermos flasks 7 to rotate through the six supporting arms 5, then the valve of the sealing cover 103 is opened so that the air pressure in the drying chamber 2 is balanced with the air pressure outside the drying chamber 2, then the extension rod of the hydraulic rod 102 is controlled to extend to push the sealing cover 103 to move upwards, after the sealing cover 103 moves a certain distance, it will rotate forty-five degrees through the guide groove obliquely arranged on the supporting frame 101, so that the sealing cover 103 is reset, at the same time, the drain valve of the drying chamber 2 is opened to drain the water in the drying chamber 2, then the operator can take out the dried thermos flask 7.

[0043] On the basis of example 1, as shown in Figures 1-12 The ventilation mechanism 12 is arranged on the piston rod 113 and used for ventilating the thermos flask 7, the ventilation mechanism 12 includes a guide arm 121 which is connected to one of the piston rods 113 through bolts, the drying chamber 2 is connected with a mounting frame 122 through bolts, the mounting frame 122 is rotatably connected with a rotating rod 123, the rotating rod 123 is provided with a spiral groove, the spiral groove of the rotating rod 123 is slidably connected with the guide arm 121, the piston rod 113 drives the guide arm 121 to rotate the rotating rod 123 through the spiral groove of the rotating rod 123, the mounting frame 122 is rotatably connected with a bidirectional reciprocating screw rod 125, the bidirectional reciprocating screw rod 125 is connected with the rotating rod 123 through an overrunning clutch 124, the mounting frame 122 is slidably connected with a sliding frame 126, the sliding frame 126 is threadedly connected with the bidirectional reciprocating screw rod 125, the sliding frame 126 is connected with a piston head 127 through bolts, the drying chamber 2 is connected with a communication pipe 128 through bolts, the communication pipe 128 communicates the inside and outside of the drying chamber 2, the communication pipe 128 is used for allowing the air outside the drying chamber 2 to enter the drying chamber 2, and the communication pipe 128 is aligned with the piston head 127.

[0044] The communication pipe 128 is provided with a filter element, and the filter element of the communication pipe 128 is used for filtering the air entering the drying chamber 2.

[0045] At the beginning, air will enter into the drying bin 2 through the communication pipe 128, so that the air pressure in the drying bin 2 will not be reduced by the vacuum mechanism 11. When the piston rod 113 reciprocating close to the bidirectional reciprocating wire rod 125 moves, the guide arm 121 will move together. When the guide arm 121 moves towards the communication pipe 128, it will drive the rotating rod 123 to rotate through the spiral groove of the rotating rod 123 by a certain angle. The rotation of the rotating rod 123 will drive the bidirectional reciprocating wire rod 125 to rotate through the overrunning clutch 124. The rotation of the bidirectional reciprocating wire rod 125 will drive the piston head 127 to move a certain distance towards the communication pipe 128 through the sliding frame 126. When the guide arm 121 moves towards the piston tube 112, it will drive the rotating rod 123 to reset. At this time, the overrunning clutch 124 does not work. In this way, the bidirectional reciprocating wire rod 125 rotates intermittently, so that the piston head 127 gradually enters the communication pipe 128. At this time, air no longer enters the drying bin 2 through the communication pipe 128. The vacuum mechanism 11 starts to reduce the air pressure in the drying bin 2, so that the air pressure in the thermos bottle liner 7 is also reduced. When the sliding frame 126 moves to one end of the bidirectional reciprocating wire rod 125 close to the communication pipe 128, the sliding frame 126 will move back to reset through the bidirectional reciprocating wire rod 125. The sliding frame 126 moves back to drive the piston head 127 to move. After the piston head 127 moves back a certain distance, it will be separated from the communication pipe 128. At this time, the air outside the drying bin 2 will flow back into the drying bin 2 through the communication pipe 128. At the same time, the filter element of the communication pipe 128 will filter the air entering the drying bin 2, thereby avoiding dust and water vapor entering the drying bin 2 together. After the air enters the drying bin 2, it will enter the vacuum interlayer of the thermos bottle liner 7 through the vacuum interface of the thermos bottle liner 7. Then continue to repeat the above operation to perform multiple air exhaust and air backflow on the vacuum interlayer of the thermos bottle liner 7. In this way, by repeatedly discharging air in the vacuum interlayer of the thermos bottle liner 7 to make clean air backflow, the vacuum interlayer of the thermos bottle liner 7 is ventilated, so that the water vapor in the vacuum interlayer of the thermos bottle liner 7 is discharged more completely, thereby further enhancing the drying effect of the thermos bottle liner 7.

[0046] Example 3: Based on example 2, as Figures 1-15The device also comprises a swing mechanism 13 arranged on the drying bin 2 for swinging the thermos flask 7, the swing mechanism 13 comprises a guide ring 131 connected to the drying bin 2 by bolts, the guide ring 131 is provided with a wave-shaped groove, the both ends of the rotating shaft of each rotating frame 6 are connected with a third gear 132 through a key groove, the two third gears 132 on the same rotating frame 6 are a group, the bottom of each supporting arm 5 is connected with a guide sleeve 133 through bolts, the six guide sleeves 133 are slidably connected with a transmission frame 134, the bottom of the six transmission frames 134 are slidably connected with the wave-shaped groove of the guide ring 131, the guide ring 131 drives the transmission frame 134 to reciprocate through the wave-shaped groove, the both sides of each transmission frame 134 are rack structures, the rack structures of the six transmission frames 134 are respectively engaged with the six groups of third gears 132, the rack structures of the transmission frame 134 are used for driving the rotating frame 6 to swing through the third gear 132.

[0047] The supporting arm 5 drives the rotating frame 6 to rotate, and the guide sleeve 133 and the transmission frame 134 are also driven to rotate, when the transmission frame 134 rotates, the transmission frame 134 reciprocates through the wave-shaped groove of the guide ring 131, so that the rack structures of the six transmission frames 134 drive the six rotating frames 6 to reciprocate up and down through the six groups of third gears 132, the six rotating frames 6 reciprocate up and down to drive the thermos flask 7 to swing, in this way, the thermos flask 7 is swung up and down while the water on the thermos flask 7 is spun off, so as to change the posture of the thermos flask 7 when the water is spun off, so that the water is not easy to remain in the dead angle of the vacuum interlayer of the thermos flask 7, thereby further enhancing the drying effect of the thermos flask 7.
