The pressure motor described in item 1 of the scope of patent application, wherein the normal direction of the first joint surface is parallel to the direction of gravity. As for the pressure motor described in item 1 of the scope of patent application, the normal direction of the first joint surface is the same as the direction of gravity. The pressure motor described in item 1 of the scope of patent application, wherein the normal direction of the first joint surface intersects the direction of gravity. In the pressure motor described in item 1 of the scope of patent application, the normal direction of the first joint surface is orthogonal to the direction of gravity. For example, the pressure motor described in the first item of the scope of patent application further includes a first outlet box, the sealed housing includes a first opening, and the first outlet box is arranged corresponding to the first opening and A sealing joint is formed with the outer wall surface of the sealed casing, and at least one cable extends to the first outlet box through the first opening. According to the pressure motor described in claim 14, wherein the first outlet box includes at least one sealed joint, and the at least one cable extends to the outside of the first outlet box through the sealed joint. For the pressure motor described in item 15 of the scope of patent application, the sealing joint includes a fixing member, a fastener, and a locking member. The fixing member forms a sealed joint with the first outlet box, and the fastener is formed by The fixing piece is restricted to buckle the cable, and the locking piece is movably arranged on the fixing piece, and the fastener is positioned on the fixing piece. For example, the pressure motor described in item 14 of the scope of patent application further includes a second outlet box, the sealed housing includes a second opening, and the second outlet box is arranged corresponding to the second opening and A sealing joint is formed with the outer wall surface of the sealed casing, and at least another cable extends to the second outlet box through the second opening. For the pressure motor described in item 17 of the scope of patent application, the second outlet box and the first outlet box are oppositely arranged on the outer wall surface of the sealed housing. For the pressure motor described in item 17 of the scope of patent application, the second outlet box and the first outlet box are adjacently arranged on the outer wall surface of the sealed housing. The pressure motor described in item 14 of the scope of patent application, wherein the at least one cable is connected to a power supply. The pressure motor described in item 1 of the scope of patent application, wherein the rotating shaft is connected to a fan blade group, and the fan blade group is arranged in the pressure vessel.
