[0024] A guide plate 104 is provided on the lower inner side of the filter box 101, a connecting pipe 106 is connected to the rear end of the liquid outlet connection plate 107, and a limiting shaped block 112 is provided on the inner sides of the left and right ends of the liquid inlet guide box 109; a first return spring 113 located on the inner side of the filter box 101 is provided on the outer end of the limiting shaped block 112, an auxiliary roller 114 is provided above the limiting shaped block 112, a second return spring 115 is provided on the upper end of the auxiliary roller 114, and a pressing rod 116 connected to the filter box 101 is provided on the inner side of the second return spring 115; the auxiliary roller 114 is provided with a second return spring 115. 14 An elastic telescopic structure is formed in the filter box 101 through the second return spring 115, the outer surface of the auxiliary roller 114 is fitted with the limiting shaped block 112, the limiting shaped block 112 is moved laterally in the filter box 101 through the first return spring 113, and the limiting shaped block 112 is connected to the liquid inlet guide box 109 by plugging; the interior of the liquid inlet guide box 109 is inclined for drainage and discharge of liquid, and a rubber sealing ring 111 is provided at the lower edge of the liquid inlet guide box 109 to be snap-connected with the filter box 101.

[0025] Specifically, before use, the liquid inlet guide box 109 is snap-fitted with the filter box 101 through the rubber sealing ring 111 bonded at the lower edge to increase the sealing performance. At this time, the snap connection between the liquid inlet guide box 109 and the limiting special-shaped block 112 can make the liquid inlet guide box 109 firmly installed on the inner side of the upper end of the filter box 101, and can be flexibly moved and adjusted under the action of the self-locking casters 102.

[0028] The four corners of the sealing back plate 201 are all provided with a first groove body 202, and the inner side of the first groove body 202 is provided with a first locking rod 203 connected to the filter box body 101, and the first locking rod 203 passes through the sealing back plate 201 through the first groove body 202 and then rotates; a first adjusting bolt 206 is provided at the connection between the sealing back plate 201 and the filter frame 204, and the filter frame 204 is snap-connected by a first damping rubber block 205 arranged on the inner side of the sealing back plate 201; the centrifugal box 209 and the annular frame 210 are connected in an annular snap-fit ​​manner, and the annular frame 210 and the second filter screen 211 are connected by bonding, and the inner upper side of the centrifugal box 209 is concave inward.

[0029] Specifically, when filtering is needed, the filter frame 204 is docked and engaged with the sealing back plate 201 through the first damping rubber block 205, and then the sealing back plate 201 and the filter frame 204 are threadedly connected by using the first adjusting bolt 206, so that the sealing back plate 201 drives the filter frame 204 to dock and engage with the front end of the filter box 101, so that the filter frame 204 can be firmly installed in the filter box 101. At this time, the sealing back plate 201 passes through the first locking rod 203 through the first slot body 202. After rotating the first locking rod 203, the sealing back plate 201 can be engaged and limited. The first filter net 207 is arranged on the inner side of the filter frame 204 with the mesh number increasing from top to bottom, so that the liquid after gastric lavage can be filtered layer by layer, so that the filtered liquid can be smoothly filtered. The centrifugal box 209 is discharged into the centrifugal box 209 along the guide plate 104. At the same time, the first servo motor 208 is turned on to rotate the centrifugal box 209. Under the action of centrifugal force, the liquid can be thrown out from the second filter screen 211 arranged on the inner side of the annular frame 210, so that impurities are accumulated in the centrifugal box 209. After the gastric lavage tube is docked and installed with the liquid outlet connecting plate 107, the pump body 105 can be opened to discharge the filtered cleaning liquid outward along the connecting pipe 106. Finally, the cleaning liquid after cleaning will enter the liquid inlet guide box 109 along the liquid inlet connecting plate 110, so as to achieve the effect of circulating filtration. The inner upper side of the centrifugal box 209 is arranged to be inclined inwardly in an arc shape, which can avoid liquid splashing and play a role in guiding reflux. The setting of the guide plate 104 can also avoid blocking the liquid when it is thrown out by centrifugal force to avoid splashing.

[0033] Specifically, after the gastric lavage operation is completed, the sealing side plate 301 is fixedly installed on the left side of the filter box 101 through the second locking rod 303. Since the upper and lower sides of the brush head 311 are fitted with the upper and lower surfaces of the first filter screen 207, when the second servo motor 304 is turned on to rotate the adjustment disk 305, the inner tooth adjustment belt 306 connected in meshing connection can drive the adjustment disk 305 and the corresponding monomer to rotate in the same direction, so that the movable positioning block 308 threadedly connected to the adjustment rod 307 drives the installation brush seat 309 to move rightward as a whole. Four sets of second adjusting bolts 310 are installed at the connection between the movable positioning block 308 and the installation brush holder 309, which can facilitate the disassembly and replacement of the installation brush holder 309 as a whole at a later time. At this time, when the installation brush holder 309 moves to the right, the brush head 311 can be used to clean the impurities adhering to the upper and lower surfaces of the first filter screen 207. After cleaning to the rightmost end, the impurities are directly discharged into the collection box 313 for unified collection.
