The seal 2 is intended to be placed on a fire extinguisher and used in conjunction with an extraction tube 28 and a feed tube 29. The seal 2 is clamped in place by means of the first clamping head 15.
The seal 2 is composed of a sealing sleeve 16, a movable cylinder 30, a connecting piece 31 and a sealing component 32. The movable tube 30 and the connecting piece 31 are positioned inside the sealing sleeve 16, and the movable tube 30 adopts an organ tube structure which can be compressed by applying external force and can restore to original state after losing the external force. The lower end of the movable cylinder 30 is also provided with an extension pipe 61 extending into the first through hole 33, and the extension pipe 61 is used for limiting the movable cylinder 30. The connecting member 31 is located at the lower end of the movable cylinder 30 and is fixedly connected with the sealing sleeve 16 by bolts (not shown in the drawings), and is fastened to the outside to fix the position thereof, thereby supporting the movable cylinder 30.

After the material guiding pipe 39 moves downwards, the material guiding pipe 39 is communicated with the fourth through hole 36 through the feeding hole 42, so that dry powder enters the material guiding pipe 39 from the fourth through hole 36 and then enters the fire extinguisher.
The lower end of the sealing sleeve 16 is provided with a mounting groove 43, the mounting groove 43 is internally provided with a sealing ring 27, the sealing ring 27 is made of rubber materials, and the sealing ring 27 is easy to deform under stress.
The middle of the sealing member 32 is hinged to the lower end of the connecting member 31, one end is hinged to the material guiding tube 39, and the other end is disposed in the fifth through hole 37.
The interior of the connector 31 also has a cavity 62 in which the sealing member 32 is placed.

When the movable cylinder 30 deforms, only after the air extraction equipment extracts air, the movable cylinder 30 is communicated with the fire extinguisher, the movable cylinder 30 is compressed under the action of external atmospheric pressure, and the compressed spring 45 can assist in pushing the movable cylinder 30 to descend, so that the air in the movable cylinder 30 is discharged quickly.
When the inside of the movable cylinder 30 is no longer in vacuum, the movable cylinder 30 needs to be recovered by self elastic force, and the elastic force is F3, and F3 is more than F2, so that the spring 45 can be compressed again when the movable cylinder 30 is recovered.
The sealing member 32 includes a rubber sleeve 46, a weight 48 mounted in a placement chamber 47, and a symmetrically disposed hinge rod 49. The rubber bush 46 has a placement chamber 47 and a support portion 50 inside, and the rubber bush 46 is located at the lower end of the fifth through hole 37. The weight 48 has a hinge end 51 at a lower end thereof, and the hinge end 51 has a first hinge shaft 52 thereon.

The rubber sleeve 46 is in the shape of a frustum with a small upper part and a large lower part. The rubber sleeve 46 can enter the lower end of the fifth through hole 37 through the positioning ring 54 to be sealed.
Since the weight 48 is provided in the seal member 32, it is naturally downward at the end of the rubber sleeve 46, and the other end pushes the guide pipe 39 upward.
When the air is exhausted, the suction force of the air exhausting equipment is larger, and after the rubber sleeve 46 reaches the lower end of the fifth through hole 37, the air inside the fire extinguisher is exhausted by the downward gravity of the weighting block 48 and the upward suction force, and after a certain time, the suction force drives the rubber sleeve 46 to move upwards, so that the rubber sleeve 46 seals the fifth through hole 37.
The middle of the hinge rod 49 is mounted on a hinge seat 57 of the connecting piece 31 through a rotating shaft 56, one end of the hinge rod 49 is provided with a first bar-shaped groove 58, the other end of the hinge rod 49 is provided with a second bar-shaped groove 59, the first hinge shaft 52 is positioned in the first bar-shaped groove 58, the lower end of the material guiding pipe 39 is provided with a second hinge shaft 60, and the second hinge shaft 60 is positioned in the second bar-shaped groove 59. When the guide tube 39 moves up and down, the second hinge shaft 60 moves in the second bar-shaped groove 59, and the first hinge shaft 52 moves in the first bar-shaped groove 58.
When in use, the fire extinguisher is placed in the placing groove 26, the fourth cylinder 21 is started, the fire extinguisher reaches the lower end of the second clamping head 20, and the upper end of the fire extinguisher is clamped and fixed through the second clamping head 20. The first cylinder 12 is then activated to push the first clamping assembly 6 downwardly so that a seal is formed between the sealing ring 27 and the fire extinguisher. The air extraction equipment is started again, so that the movable barrel 30 is compressed, the material guide pipe 39 and the air guide pipe 38 move downwards, the material guide pipe 39 pushes the hinging rod 49, the rubber sleeve 46 is upwards, the fifth through hole 37 is blocked, and the feeding port 42 is communicated with the fourth through hole 36, so that feeding can be realized. During feeding, air suction is continued, the rubber sleeve 46 at the moment cannot fall by the gravity of the weighting block 48, then dry powder in the powder storage cylinder can enter the powder storage cylinder, when the air pressure in the fire extinguisher is consistent with the air pressure in the fire extinguisher, the powder storage cylinder is not fed, a valve connected with the powder storage cylinder is closed, and meanwhile, the air suction valve is also closed, so that the next fire extinguisher is replaced for filling.
Of course, when the distance between the rubber sleeve 46 and the fifth through hole 37 is very small, a large suction force is applied, and the rubber sleeve is quickly sucked to block the fifth through hole 37, so that the time for taking place is short, and the dry powder cannot enter the fifth through hole 37 and be pumped into the device.
In addition, the sealing cover 44 can be replaced by a pressure sensor, when the movable cylinder 30 is in a natural state, the spring 45 is compressed, the spring 45 can apply pressure to the pressure sensor, the pressure sensor can transmit signals to the electromagnetic valve, and the electromagnetic valve is closed after receiving the signals.
