[0037] like Figure 1 , Figure 2 , Figure 3 , Fig.11As shown, a lubrication mechanism 11 cooperating with the cylindrical block 6 is provided at the inner bottom of the mobile box 1, and the lubrication mechanism 11 includes a lubrication oil tank 1101 fixedly arranged at the inner bottom of the mobile box 1, and lubrication oil is stored in the lubrication oil tank 1101. An oil inlet 1106 is provided on the middle upper side of the lubrication oil tank 1101, and lubrication oil can be added through the oil inlet 1106. A fixed groove 1102 located above the oil inlet 1106 is fixedly arranged on the upper side of the lubrication oil tank 1101, and a through hole 1105 located above the oil inlet 1106 is provided on the inner bottom of the fixed groove 1102. A sponge block 1103 is provided on the inner side of the fixed groove 1102, and a sponge column 1104 is fixedly connected to the bottom of the sponge block 1103, which passes through the through hole 1105 and the oil inlet 1106 and extends to the inside of the lubrication oil tank 1101.

In addition, since the cylindrical block 6 slides and squeezes on the surface of the straw 15, heat is generated on the surface of the straw 15. The pus inside the straw 15 can be dissolved by the heat, which facilitates the flow of pus and avoids clogging the straw 15.

[0038] like Figure 1 , Figure 2 , Figure 8 , Fig. 9As shown, the sealing assembly of the connecting tube 1315 is sealed and matched, and the sealing assembly includes a fixing plate 1308 fixedly arranged on the inner side wall of the liquid inlet cylinder 1301, a return spring 1309 is fixedly arranged on one side of the fixing plate 1308, and a sealing plug 1310 that is sealed and matched with the connecting tube 1315 is fixedly arranged on one end of the return spring 1309, and a triangular cutter 1311 located on the inner side of the connecting tube 1315 is fixedly arranged on one side of the sealing plug 1310. When in use, when negative pressure is generated in the liquid inlet cylinder 1301, the sealing plug 1310 on the inner side of the connecting tube 1315 is attracted to slide into the inner side of the liquid inlet cylinder 1301, so that one end of the connecting tube 1315 is opened, so that the connecting tube 1315 is opened. 315 is connected with the liquid inlet cylinder 1301, and finally the pus on one side of the connecting tube 1315 is sucked into the inside of the liquid inlet cylinder 1301 through negative pressure. When the pus flows on one side of the sealing plug 1310, the pus will hit the triangular cutter 1311 on one side of the sealing plug 1310. The triangular cutter 1311 can make the pus to be initially cut, and the reset spring 1309 on the other side of the sealing plug 1310 can be compressed. When negative pressure suction is not performed, the elastic force of the reset spring 1309 can make the sealing plug 1310 seal the connecting tube 1315, play the role of anti-backflow, prevent pus from flowing back to the wound site, and avoid infection of the wound.

When negative pressure is generated in the suction tube 15, negative pressure is generated in the liquid inlet cylinder 1301 at one end of the suction tube 15, which attracts the sealing plug 1310 on the inner side of the connecting tube 1315 to slide into the inner side of the liquid inlet cylinder 1301, so that one end of the connecting tube 1315 is opened, so that the connecting tube 1315 is connected with the liquid inlet cylinder 1301, and finally the pus on one side of the connecting tube 1315 is sucked into the inside of the liquid inlet cylinder 1301 by the negative pressure. When the pus flows on one side of the sealing plug 1310, the pus will hit the sealing plug. On the triangular cutter 1311 on one side of 1310, the pus can be initially cut by the triangular cutter 1311, and then the pus will enter the inner side of the liquid inlet tube 1301, and the pus will push the impeller 1307 to rotate, driving the rotating rod 1306 to rotate, and then the rotating rod 1306 drives multiple fan-shaped cutters 1305 to rotate, so that the pus is cut into small pieces, and a secondary cutting is performed to cut the viscous liquid in the pus into pieces, which is convenient for flowing in the straw 15, thereby improving the efficiency of negative pressure suction.
