The frame 1 is provided with a motor 6 for driving the pulverizing blade 3 to rotate, and the output shaft of the motor 6 is fixedly connected to the pulverizing blade 3 via a transmission shaft 61. The cutting surface of the pulverizing blade 3 is perpendicular to the axis of the transmission shaft 61.

[0030] This design allows solid daily chemical products, such as soap, to be pulverized and sampled, avoiding manual cutting operations, and the pulverized samples are also easy to dissolve.

[0031] According to one embodiment of the present invention, the bottom of the box 2 is provided through, and the filter screen 4 is fixedly connected to the inner side wall of the box 2.

[0032] This design achieves the purpose of filtration, preventing larger particles from falling into the collection box 5, and instead allowing them to continue to be crushed by the crushing blades 3 above the filter screen.

[0033] According to one embodiment of the present invention, the diameter of the filter holes of the filter screen 4 is no greater than 5 mm.

[0034] According to one embodiment of the present invention, the filter screen 4 is provided with an arc-shaped surface that matches the rotation path of the crushing blade 3.
