A filter layer 6, a sponge layer 7 and a filter screen 12 are provided. A multi-stage filtration design is adopted to reduce the number of crystals that will appear in the flux due to the addition of various auxiliary materials during the production process, thereby improving the quality of the produced flux. A detachable sponge layer 8 and a filter screen 12 are provided. The top plate 3 is opened and the sponge layer 7 can be taken out for cleaning using the handle 8. The filter screen 12 can be taken out for replacement and cleaning using the movable block 13, thereby preventing the filter device from being blocked and improving the filtration efficiency.

[0024] Furthermore, the valve 5 is arranged at the center of the top plate 3, the liquid inlet 4 is offset from the center of the top plate 3, and the opening at the bottom of the liquid inlet 4 is within the opening radius of the sponge layer 7, so that the liquid inlet 4 will not affect the use of the valve 5 while ensuring that the flux can smoothly enter the sponge layer 7.

[0025] Furthermore, a plurality of filtering holes are provided on the surface of the filter layer 6 to discharge the soldering flux after the initial filtering out of the filter layer 6 .

[0026] Furthermore, the outer wall of the sponge layer 7 fits with the inner wall of the filter layer 6 , and the height of the sponge layer 7 and the handle 8 is lower than the height of the outer shell 1 . The sponge layer 7 first filters the crystals that may exist inside the flux and then discharges them from the filter layer 6 .

[0027] Furthermore, the stirring blade 10 is arranged at the center of the filter layer 6 , and the stirring of the stirring blade 10 accelerates the filtering process.

[0028] Furthermore, a plurality of filter holes are provided on the surface of the filter 12, a slot is provided in the liquid outlet 11, the filter 12 is inserted into the slot, and the soldering flux is filtered twice through the filter 12 when discharged from the liquid outlet 11, thereby further improving the quality of the produced soldering flux.

[0029] Furthermore, the sponge layer 7 is made of hard sponge, and the sponge layer 7 will not fall over due to adsorbing a portion of the soldering flux or crystallizing.

[0030] Working principle: when filtering the flux, first turn on the motor 9 to drive the stirring blade 10 to stir, and add the flux to be filtered into the device through the liquid inlet 4. The flux first passes through the sponge layer 7 to filter out most of the impurities such as crystals it carries, thereby improving the quality of the produced flux. The material of the sponge layer 7 is a hard sponge, and the sponge layer 7 will not fall over due to the adsorption of a part of the flux or crystallization. It is discharged into the interlayer between the filter layer 6 and the outer shell 1 through the filter holes on the filter layer 6 to wait for secondary filtration. The stirring of the flux by the stirring blade 10 accelerates the filtration process. When the flux is discharged from the liquid outlet 11, the filter screen 12 arranged on the liquid outlet 11 performs secondary filtration on the flux, basically filters out the impurities, further improves the quality of the flux, and completes the filtration during the production of the flux. When the device needs to be cleaned, first open the top plate 3 through the valve 5, and lift the sponge layer 7 through the handle 8 arranged on the sponge layer 7 for cleaning. Pull out the filter screen 12 through the movable block 13 for replacement or cleaning.
