[0034] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0035] It should be noted that in the prior art, PCB circuit boards need to be cleaned during the manufacturing process, but the PCB circuit boards are easily contaminated by fine debris or dust during the cleaning process, so the cleaning liquid needs to be filtered. However, the current cleaning liquid filter device has a relatively complicated disassembly structure, which is usually fixed with bolts. It needs to be twisted with tools during disassembly, which makes it inconvenient to replace the filter device.

[0036] like Figures 1 to 4 As shown, according to some embodiments of the utility model, the cleaning liquid filtering device includes:

[0037] Housing 100;

[0038] A connecting cavity 102 is provided to open the interior of the housing 100, and the connecting cavity 102 passes through one end of the housing 100;

[0039] A mounting seat 200 is detachably disposed at one end of the housing 100. A filter core 210 is disposed at one end of the mounting seat 200. A filter cavity 212 is formed inside the filter core 210. The filter core 210 is located inside the connecting cavity 102. A liquid inlet pipe 120 is disposed at one end of the housing 100. The liquid inlet pipe 120 communicates with the inside of the filter cavity 212. A liquid outlet pipe 130 is disposed at one side of the housing 100. The liquid outlet pipe 130 communicates with the connecting cavity 102.

[0040] There are two fixed posts 201, which are respectively arranged on both sides of the mounting base 200. One end of the fixed post 201 is provided with a plug-in end 206. Setting grooves 150 are provided on both sides of the shell 100. A fixing block 162 is hinged in the setting groove 150. A fixed slot 163 is provided on one side of the fixing block 162. The fixed slot 163 is inclined. Two sliding slots 140 are provided at the other end of the shell 100. The two sliding slots 140 extend to the setting slots 150 on both sides of the shell 100 respectively. When the fixed post 201 passes through the fixed slot 163, the plug-in end 206 protrudes out of the setting slot 150 so that the fixed slot 163 is plugged with the plug-in end 206.

[0041] It can be understood that when the filter core 210 needs to be disassembled, the fixing block 162 is rotated, and the fixing slot 163 of the fixing block 162 gradually disengages from the plug-in end 206 of the fixing column 201, and the fixing column 201 can slide out of the sliding slot 140, so that the fixing column 201 drives the mounting seat 200 away from the outer shell 100, and the mounting seat 200 drives the filter core 210 to disengage from the connecting cavity 102, thereby eliminating the need for bolts or external tools, thereby facilitating the replacement of the filter core 210.

[0042] In addition, when the filter core 210 needs to be installed, the filter core 210 is inserted into the connecting cavity 102, so that the mounting seat 200 is close to the outer shell 100, and the fixed clamping column 201 of the mounting seat 200 slides into the setting groove 150 along the sliding groove 140. At this time, the plug-in end 206 protrudes out of the setting groove 150. When the fixing block 162 is rotated, since the fixed clamping groove 163 of the fixing block 162 is inclined, when the fixed clamping groove 163 of the fixing block 162 is plugged with the plug-in end 206 of the fixed clamping column 201, the fixed clamping column 201 is blocked from sliding out of the sliding groove 140, thereby facilitating the installation of the filter core 210.

[0043] It should be noted that when the cleaning liquid flows in from the liquid inlet pipe 120, the liquid inlet pipe 120 passes through the filter cavity 212 of the filter core 210, so that the filter core 210 filters the cleaning liquid, and the filtered cleaning liquid is discharged through the liquid outlet pipe 130 on one side of the outer shell 100, thereby preventing the cleaning liquid from carrying dust and adhering to the PCB circuit board.

[0044] like Figures 1 to 4As shown, according to some embodiments of the present invention, a pull rod 160 is further included. The pull rod 160 is arranged horizontally, and movable arms 161 are arranged on both sides of the pull rod 160. The movable arms 161 on both sides of the pull rod 160 are respectively connected to the fixed blocks 162 on both sides of the shell 100.

[0045] It can be understood that when the pulling rod 160 is pulled, the pulling rod 160 drives the movable arms 161 on both sides of the pulling rod 160 to rotate, and the movable arms 161 on both sides of the pulling rod 160 respectively drive the fixed blocks 162 on both sides of the shell 100 to rotate, thereby facilitating the synchronous rotation of the fixed blocks 162, so as to facilitate the connection or disconnection of the fixed slot 163 of the fixed block 162 with the plug-in end 206 of the fixed column 201.

[0046] like Figures 1 to 4 As shown, according to some embodiments of the present invention, an installation cavity 101 is opened at one end of the shell 100, the installation cavity 101 is connected to the connecting cavity 102, the sliding groove 140 is connected to the installation cavity 101, the installation cavity 101 matches the shape of the mounting seat 200, and the mounting seat 200 is plugged into the installation cavity 101.

[0047] It can be understood that when the filter core 210 is inserted into the connecting cavity 102, the mounting seat 200 is plugged into the mounting cavity 101. Since the shapes of the mounting cavity 101 and the mounting seat 200 match, the movable space after the mounting seat 200 is inserted into the mounting cavity 101 is reduced, so that the filter core 210 can be stably plugged into the inside of the connecting cavity 102.

[0048] like Figure 5 As shown, according to some embodiments of the utility model, a limiting seat 202 is provided at one end of the mounting seat 200, a limiting cavity 205 is opened at one end of the limiting seat 202, a connecting seat 211 is provided at one end of the filter core 210, the shape of the connecting seat 211 matches the limiting cavity 205, and the connecting seat 211 is plugged into the limiting cavity 205.

[0049] It is understandable that by plugging the connecting seat 211 at one end of the filter core 210 into the limiting cavity 205, it is convenient to limit the installation position of one end of the filter core 210 to prevent the filter core 210 from detaching from the mounting seat 200 under the action of water pressure.

[0050] like Figures 1 to 4As shown, according to some embodiments of the utility model, a limit plate 110 is provided at one end of the shell 100, and the liquid inlet pipe 120 is installed on one side of the limit plate 110. A liquid inlet groove 121 is opened inside the limit plate 110, and the liquid inlet groove 121 connects the filter cavity 212 and the liquid inlet pipe 120. The other side of the limit plate 110 is located inside the connecting cavity 102, and a liquid outlet groove 131 is opened on one side of the shell 100, and the liquid outlet groove 131 connects the connecting cavity 102 and the liquid outlet pipe 130.

[0051] It can be understood that when the cleaning liquid flows in from the liquid inlet pipe 120, the cleaning liquid flows through the filter cavity 212 through the liquid inlet groove 121. After the cleaning liquid is filtered by the filter inner core 210, the cleaning liquid flows out from the outer edge of the filter inner core 210, so that the filtered cleaning liquid passes through the liquid outlet groove 131 and then is discharged from the liquid outlet pipe 130, thereby facilitating the filtering of the cleaning liquid and preventing the cleaning liquid from carrying dust into the PCB circuit board.

[0052] like Figure 4 As shown, according to some embodiments of the present invention, a limiting ring 122 is provided on the other side of the limiting plate 110 , the limiting ring 122 is located inside the connecting cavity 102 , and the other end of the filter core 210 is plugged into the inner ring of the limiting ring 122 .

[0053] It can be understood that by plugging the connecting seat 211 at the other end of the filter core 210 into the inner ring of the limiting ring 122, it is convenient to limit the installation position of the other end of the filter core 210, further improve the firmness of the filter core 210, and prevent the filter core 210 from detaching from the mounting seat 200 under the action of water pressure.

[0054] like Figure 4 As shown, according to some embodiments of the present invention, a plurality of connecting grooves 125 are formed on the outer edge of the limiting ring 122 , and the connecting grooves 125 connect the interior of the limiting ring 122 and the connecting cavity 102 .

[0055] It can be understood that after the cleaning liquid is filtered through the filter core 210, part of the filtered cleaning liquid passes through the connecting groove 125 of the limiting ring 122 and is discharged through the liquid outlet pipe 130, thereby increasing the flow area of ​​the cleaning liquid and avoiding the limiting ring 122 from blocking the filtered liquid.

[0056] like Figure 4 As shown, according to some embodiments of the present invention, a first limiting groove 123 is opened on the other side of the limiting plate 110 , the shape of the first limiting groove 123 matches the shape of the limiting ring 122 , and one end of the limiting ring 122 is plugged into the first limiting groove 123 .

[0057] It is understandable that by plugging one end of the limiting ring 122 into the first limiting groove 123 , the position of the limiting ring 122 can be fixed to prevent the limiting ring 122 from detaching from the limiting plate 110 under the action of water pressure, thereby improving the stability of the limiting ring 122 .

[0058] like Figure 4 As shown, according to some embodiments of the present invention, a second limiting groove 124 is opened on the other side of the limiting plate 110 , the shape of the second limiting groove 124 matches the shape of the shell 100 , and one end of the shell 100 is plugged into the first limiting groove 123 .

[0059] It is understandable that by plugging one end of the housing 100 into the first limiting groove 123 , the limiting plate 110 is prevented from being separated from the housing 100 under the action of water pressure, thereby improving the stability of the limiting plate 110 .

[0060] like Figures 1 to 4 As shown, according to some embodiments of the present invention, a mounting head 203 is disposed at the other end of the mounting seat 200 , and a mounting slot 204 is formed on the outer edge of the mounting head 203 , and the mounting slot 204 is used to connect to an external frame.

[0061] It is understandable that, by installing the card slot 204 , the housing 100 can be easily fixed to an external frame, so that the filter core 210 inside the housing 100 can filter the cleaning liquid.

[0062] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
