Specifically, the pressure chamber includes a chamber body 100, a power mechanism 200, a door assembly 300 and a purification and filtration device 400; an opening 110 is provided on the chamber body 100, the power mechanism 200 is provided on the inner wall of the chamber body 100 and is located on one side of the opening 110, the power mechanism 200 includes a transmission assembly 210 and a drive assembly 220, the transmission assembly 210 is transmission-connected to the drive assembly 220, and the connecting rod 211 in the transmission assembly 210 rotates relative to the drive assembly 220; the door assembly 300 is movably connected to the connecting rod 211, the power mechanism 200 drives the door assembly 300 to move to seal the opening 110, and the purification and filtration device 400 is provided in the chamber body 100 corresponding to the opening 110.

[0042] Since a power mechanism 200 is provided on one side of the chamber body 100 corresponding to the opening 110, and the door body assembly 300 is movably connected to the connecting rod 211 which can rotate relative to the driving assembly 220. When the source liquid needs to be purified or filtered, the source liquid is placed in the purification and filtering device 400 in the chamber body 100, and then the driving assembly 220 is started, and the driving assembly 220 drives the transmission assembly 210 to move. When the door body assembly 300 reaches the opening 110 and the connecting rod 211 abuts against the stopper 213, the connecting rod 211 rotates upward relative to the driving assembly 220 to drive the door body assembly 300 to flip upward and seal the opening 110; then, the chamber body 100 is pressurized by the pressurizing assembly in the pressure chamber to meet the required pressure when purifying or filtering the source liquid in the purification and filtering device 400, thereby improving the quality and speed of purifying or filtering the source liquid in the purification and filtering device 400. After the purification or filtration of the source liquid in the purification and filtration device 400 is completed, the driving assembly 220 drives the transmission assembly 210 to move again, so that the connecting rod 211 in the transmission assembly 210 rotates again relative to the driving assembly 220, and the sealing of the door assembly 300 on the opening 110 is released, so as to complete other processes. In addition, since the power mechanism 200 and the door assembly 300 are both arranged in the warehouse body 100, when the door assembly 300 seals the opening 110 and pressurizes the interior of the warehouse body 100, under the action of the internal pressure, the sealing effect and sealing reliability of the door assembly 300 on the opening 110 are guaranteed.

[0043] In an optional technical solution of the present embodiment, the opening 110 is arranged on the top wall 120 of the warehouse body 100 and is arranged close to the second side wall 140 of the warehouse body 100. The transmission assembly 210 also includes a transmission rod 212, which is transmission-connected to the driving assembly 220. The two ends of the connecting rod 211 are rotationally connected to the door body assembly 300 and the transmission rod 212 respectively, and the transmission rod 212 is parallel to the opening 110.

[0044] The opening 110 can be arranged at any position of the top wall 120 or the side wall of the bin body 100 according to actual needs. In this embodiment, the opening 110 is arranged at the top wall 120 of the bin body 100 and is arranged close to the second side wall 140 of the bin body 100. Figures 1 to 3 and Figure 5As shown, the transmission rod 212 and the door body assembly 300 are parallel to the opening 110 to ensure the transmission effect connected to the transmission assembly 210 and to ensure that the sealing effect at various locations is the same when the opening 110 is sealed; the opening 110 is arranged on the top wall 120 of the warehouse body 100 and is arranged close to the second side wall 140 of the warehouse body 100, the first end of the connecting rod 211 is rotatably connected to the transmission rod 212, and from the third side wall 150 to the second side wall 140, the second end of the connecting rod 211 is inclined in the direction close to the top wall 120, the door body assembly 300 is rotatably connected to the second end of the connecting rod 211, and the transmission rod 212 is connected to the driving assembly 220. When the source liquid needs to be purified or filtered, the source liquid is placed in the purification and filtering device 400 in the chamber 100, and then the driving assembly 220 is started. The driving assembly 220 drives the transmission rod 212 to move, so that the transmission rod 212 moves in a direction close to the second side wall 140. At this time, the second side wall 140 also has a limiting effect. When the connection between the transmission rod 212 and the connecting rod 211 abuts against the second side wall 140, the connecting rod 211 rotates upward relative to the transmission rod 212 to drive the door assembly 300 to move upward, so that the door assembly 300 reaches the opening 110 and closes the opening 110. 0 seal; after the purification or filtration of the source liquid in the purification and filtration device 400 is completed, the pressure in the warehouse body 100 is released, the door body assembly 300 is no longer under pressure, and the driving assembly 220 drives the transmission rod 212 to move again, so that the transmission rod 212 moves in the direction away from the second side wall 140 to release the abutment relationship between the connection between the second end of the transmission rod 212 and the connecting rod 211 and the second side wall 140. At the same time, under the action of the gravity of the door body assembly 300, the connecting rod 211 rotates downward relative to the transmission rod 212 to release the sealing of the door body assembly 300 on the opening 110, so as to complete other processes.

Both of the above-mentioned configurations can realize that when the bin body 100 needs to be sealed, the driving assembly 220 drives the connecting rod 211 to move, so that the connection between the second end of the transmission rod 212 and the connecting rod 211 abuts against the stopper 213, so that the connecting rod 211 rotates upward to complete the sealing of the door assembly 300 to the opening 110; and in the above-mentioned two configurations, the opening 110 can be arranged at any position of the top wall 120. The specific setting method is selected according to specific needs, and it can achieve the technical effect that the limit member 213 assists the connecting rod 211 to complete the sealing of the opening 110.

[0050] The two transmission assemblies 210 are symmetrically connected to the door assembly 300 about the center of the door assembly 300 to improve the movement strength and movement stability when driving the door assembly 300. When the two transmission assemblies 210 are driven separately by the two drive assemblies 220, there is no need to set the connecting piece 230. The transmission rod 212 in the transmission assembly 210 is connected to the corresponding drive assembly 220 to ensure the movement effect of the two transmission assemblies 210. When the two transmission assemblies 210 are driven uniformly by one drive assembly 220, the two transmission assemblies 210 are connected to the drive assembly 220 through the connecting piece 230.
