[0037] As shown in Figures 1 to 5 the lower portion of the defoaming cylinder 1 is fixedly connected with the liquid discharge pipe 101. The nano ink in the defoaming cylinder 1 is discharged through the liquid discharge pipe 101.

[0038] As shown in Figures 4 to 5As shown, a flow guide cover 203 is fixedly installed in the filter cartridge 201. The flow guide cover 203 guides and transports the nano-ink guided out of the liquid inlet pipe 204.

[0039] like Figures 4 to 5 As shown, a sealing cylinder gasket 205 is arranged between the filter cylinder 201 and the cylinder cover 202. The sealing cylinder gasket 205 is provided to improve the connection sealing performance between the filter cylinder 201 and the cylinder cover 202.

[0040] Specifically, the filter cartridge 201, the cartridge cover 202 and the sealing cartridge gasket 205 cooperate to form a closed filter space, which facilitates providing a filter space for the nano-ink transported by the discharge pipe 101.

[0041] like Figures 4 to 5 As shown, the filter cartridge 201 and the cartridge cover 202 are fixedly connected by multiple sets of evenly distributed assembly bolts 206.

[0042] like Figures 1 to 5 As shown, a supporting inner ring 207 is fixedly connected to the inner wall of the filter cartridge 201, and the supporting inner ring 207 is sleeved under the guide cover 203.

[0044] like Figures 4 to 5 As shown, a liquid delivery pipe 209 is fixedly connected to the bottom of the filter cartridge 201. The nano-ink filtered in the filter cartridge 201 is led out through the liquid delivery pipe 209.

[0045] like Figures 4 to 5 As shown, a return pipe 210 is connected between the liquid delivery pipe 209 and the liquid medicine cartridge 103.

[0047] As shown in the Figures 1 to 5 assembly limiting sleeve 301 is threadedly connected with the connecting limiting column 302. The connecting limiting column 302 is assembly-limited through the threaded connection with the assembly limiting sleeve 301. Meanwhile, the assembly limiting sleeve 301 can be closed and limited by the connecting limiting column 302.

[0048] As shown in the Figures 1 to 5 connecting limiting column 302 is fixedly connected with a filter screen cylinder 303 at one end in the filter cartridge 201, and the filter screen cylinder 303 is in communication with the flow guide cover 203. The filter screen cylinder 303 performs impurity filtering treatment on the nano ink transported in the flow guide cover 203.

By obliquely arranging the filter screen cylinder 303, the nano ink in the flow guide cover 203 can be transported in the filter screen cylinder 303 along the flow guide pipe 304. Since the filter screen cylinder 303 is obliquely arranged, the nano ink transported in the filter screen cylinder 303 can flush the inner wall of the filter screen cylinder 303, thereby ensuring the effect of impurity filtering of the nano ink by the filter screen cylinder 303.

[0050] As shown in the Figures 1 to 5 a pair of flow guide pipes 304 are fixedly assembled below the flow guide cover 203, the pair of flow guide pipes 304 are symmetrically distributed on both sides of the flow guide cover 203, and the pair of flow guide pipes 304 are sleeved on the outer side of the filter screen cylinder 303. The pair of flow guide pipes 304 play a role of connection limiting on the filter screen cylinder 303 and the flow guide cover 203. The nano ink guided in the flow guide cover 203 is transported to the filter screen cylinder 303 along the flow guide pipe 304, thereby improving the full filtering of the nano ink by the filter screen cylinder 303.

[0051] As shown in the Figures 1 to 5 a limiting top plate 305 is fixedly connected with the connecting limiting column 302 at one end outside the assembly limiting sleeve 301.

Meanwhile, the limiting top plate 305 and the assembly limiting sleeve 301 can be extruded to improve the connection sealing property of the connecting limiting column 302 and the assembly limiting sleeve 301.

[0052] As shown in the Figures 1 to 5As shown, the sealing ring 306 is arranged between the limiting top plate 305 and the assembly limiting sleeve 301, and the sealing ring 306 is sleeved outside the connecting limiting column 302. The sealing ring 306 improves the connection sealing performance of the connecting limiting column 302 and the assembly limiting sleeve 301.

[0053] In specific use, the nanometer ink in the defoaming cylinder 1 can be transported into the filter cylinder 201 along the liquid discharge pipe 101 and the liquid inlet pipe 204, the nanometer ink transported by the liquid inlet pipe 204 can be temporarily stored in the flow guide cover 203 under the action of the liquid inlet pipe 204, and then transported into the filter screen cylinder 303 along the flow guide pipe 304, the nanometer ink is filtered by the filter screen cylinder 303, and the filtered nanometer ink can be transported into the liquid medicine cylinder 103 for storage along the liquid conveying pipe 209 and the backflow pipe 210.

[0054] In the filtering process, the impurities in the nanometer ink are temporarily stored in the filter screen cylinder 303, and the nanometer ink transported along the flow guide pipe 304 continuously washes the inner wall of the filter screen cylinder 303, thereby ensuring the continuous filtering effect of the filter screen cylinder 303 on the nanometer ink. At the same time, the state of the impurities accumulated in the filter screen cylinder 303 can be observed and judged through the observation window 208, when the filter screen cylinder 303 needs to be disassembled and cleaned, the connecting limiting column 302 is rotated by applying force to the driving handle 307, so that the connecting limiting column 302 can be disassembled under the action of the internal and external threads, and the filter screen cylinder 303 can be cleaned after disassembly, thereby improving the convenience of cleaning the filter screen cylinder 303.

[0055] It is apparent for those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
