[0023] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0024] like Figure 1-5As shown, the wall-type negative pressure suction device includes a moving component 1, the top of the moving component 1 is fixedly connected to a wall 2, a plurality of collecting barrels 3 are arranged on the side of the wall 2, a connecting pipe 4 is inserted on the top of the plurality of collecting barrels 3, a connecting hose is arranged between one of the collecting barrels 3 and the wall 2, and a connecting pipe 4 is arranged between each of the other three collecting barrels 3, a fixing block 5 is fixedly connected to the oblique angle of the wall 2, a pipeline for allowing secretions, blood, tissue fluid and other substances to enter the wall 2 from the suction component 6 is arranged on the side of the fixing block 5, a pressure gauge 9 is fixedly connected to the top of the suction component 6, and the pressure gauge 9 is used to confirm whether the pressure during use is normal, and the top and bottom screws of the suction component 6 The filter cartridge 10 is connected with a filter groove, a long tube 11 is inserted into the outer wall of the suction component 6, and a blocking device 7 is arranged on the inner wall of the suction component 6. The blocking device 7 comprises a long plate 71, and the side of the long plate 71 is fixedly connected to the inner wall of the suction component 6. The long plate 71 can prevent the floating block 72 from falling into the filter cartridge 10. The inner wall of the suction component 6 is fixedly connected with a limiting slide 77, and the limiting slide 77 can limit the moving position of the floating block 72. The inner wall of the limiting slide 77 is slidably connected with a limiting block 73, and the side of the limiting block 73 is fixedly connected with the floating block 72, and the top of the floating block 72 is fixedly connected with a blocking plate 74. The inner wall of the suction component 6 is fixedly connected with a fixing ring 75, and a circular groove 76 is provided at the bottom of the fixing ring 75.

[0025] The bottom of the floating block 72 contacts the bottom of the long plate 71 , and a gap is provided between the limiting block 73 and the long plate 71 .

[0026] The fixing ring 75 is located on the displacement track of the blocking plate 74 , and the circular groove 76 is set to two-thirds of the blocking plate 74 . Because the blocking plate 74 is larger than the circular groove 76 , the blocking plate 74 will block the circular groove 76 , thereby preventing secretions, blood, tissue fluid and other substances from flowing back into the wall 2 .

[0027] According to the above structure, when the collecting bucket 3 and the filter cartridge 10 are full, the secretions, blood, tissue fluid and other substances inside the suction component 6 will cause the floating block 72 to move upward through its own buoyancy, and the movement of the floating block 72 will drive the limiting block 73 to slide on the inner wall of the limiting slide 77. At the same time, the movement of the floating block 72 will drive the blocking plate 74 to move. When the blocking plate 74 moves to the bottom of the fixing ring 75, because the blocking plate 74 is larger than the circular groove 76, the blocking plate 74 will block the circular groove 76, thereby preventing the secretions, blood, tissue fluid and other substances from flowing back into the wall 2.

[0028] like Figure 1-5As shown, an anti-cross infection device 8 is provided at the bottom of the blocking plate 74, and the anti-cross infection device 8 includes a movable plate 81, and the top of the movable plate 81 is slidably connected to the bottom of the blocking plate 74. When the movable plate 81 moves, it will contact the arc block 85, so that the movable plate 81 compresses the spring 87, and the two sides of the movable plate 81 are fixedly connected with fixed rods 82, and the circumferential surfaces of the two fixed rods 82 are fixedly connected with knocking rods 83. The inner wall of the attraction component 6 is fixedly connected with a connecting plate 84, and the side of the connecting plate 84 is fixedly connected with a plurality of arc blocks 85. The plurality of arc blocks 85 can pass through the moving frequency of the movable plate 81, and the bottom of the blocking plate 74 is fixedly connected with a limiting plate 86, and a spring 87 is arranged between the limiting plate 86 and the movable plate 81, and the spring 87 will drive the movable plate 81, the fixed rod 82, and the knocking rod 83 to reset through its own elastic force.

[0029] The movable plate 81 is set to an arc shape, and the end of the movable plate 81 away from the blocking plate 74 is set to a semicircle. A plurality of arc blocks 85 are located on the displacement track of the semicircular end of the movable plate 81. When the movable plate 81 moves, it contacts the arc block 85, causing the movable plate 81 to compress the spring 87 and drive the knocking rod 83 away from the inner wall of the attraction component 6.

[0030] The knocking rod 83 is configured to be arc-shaped, and one end of the knocking rod 83 away from the fixing rod 82 contacts the inner wall of the attraction component 6 .

[0031] According to the above structure, the blocking plate 74 will drive the moving plate 81 to move during the movement, and the movement of the moving plate 81 will drive the fixed rod 82 to move, and the movement of the fixed rod 82 will drive the knocking rod 83 to move. At the same time, the moving plate 81 will contact the arc block 85 when moving, so that the moving plate 81 compresses the spring 87 and drives the knocking rod 83 away from the inner wall of the suction component 6. When the moving plate 81 does not contact the arc block 85 when moving, the spring 87 will drive the moving plate 81, the fixed rod 82, and the knocking rod 83 to reset through its own elastic force, and so on, so that the knocking rod 83 knocks on the inner wall of the suction component 6, thereby avoiding the adhesion of secretions, blood, tissue fluid and other substances to the inner wall of the suction component 6, resulting in cross infection problems during the next use.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
