[0036] A particle size analyzer is a device used to measure the particle size distribution in a material. It decomposes the material into particles of different sizes and determines the size range and quantity of each particle through various methods (such as sieving, laser scattering, etc.), thereby providing a detailed understanding of the particle distribution in the material. This information is crucial for research and applications in many fields, including soil science, materials engineering, the pharmaceutical industry, etc.

[0037] Existing particle size analyzers are large in size and complex in operation, usually requiring operators with professional training to operate proficiently, which limits their use in some application scenarios.

[0038] Referring to Figures 1 to 11 , the present application provides a particle size analyzer, including a substrate 100, a measurement component 200, and a control board component 300.

[0039] The measurement component 200 includes a mounting plate 210 and a measurement seat 220. The mounting plate 210 is mounted on the substrate 100 through columns 211.

The power supply drive board 302 is connected to the signal acquisition board 301.

[0040] A sample and a diluent are added to the detection card 1. The detection card 1 is inserted into the slot 221 of the measurement component 200. The detection card 1 is connected to two electrodes 222 in the slot 221, so that the diluent and the sample on the detection card 1 form a circuit with the chip micropores on the detection card 1. When the sample particles on the detection card 1 pass through the chip micropores, the resistance of the circuit will change, thereby generating a potential pulse signal. The potential pulse signal will be collected by the signal acquisition board 301. The signal acquisition board 301 transmits the collected signal to a computer for analysis through software, so as to obtain the result. This particle size analyzer control board assembly 300 is arranged between the substrate 100 and the mounting plate 210, with a more compact overall structure and a smaller structural volume. During the detection process, only the detection card 1 needs to be inserted, and subsequent detections will be automatically performed through the Coulter principle. Therefore, the operation is easy and it is more convenient to promote in practical applications.

[0041] In some embodiments, the particle size analyzer further includes a box body 400. The box body 400 is connected to the substrate 100 and covers the outside of the measurement component 200 and the control board assembly 300. The box body 400 forms protection for the measurement component 200 and the control board assembly 300.

The two rollers 521 on the upper and lower sides of the door panel 520 are respectively assembled in the two guide grooves 511 on the upper and lower frames of the door frame 510. When the door panel 520 is being closed, when the roller 521 moves to the bent section of the guide groove 511, the door panel 520 will move forward to be flush with the front end face of the door frame 510, which can make the closing property of the sliding door 500 better.

The electrode 222 connects the lower measurement base 224 and the upper measurement cover 225 through a connecting seat 226. The electrode 222 is provided with a pin, and the pin is located inside the slot 221.

[0052] Specifically, after the upper measurement cover 225 is connected to the lower measurement base 224, the flared structure on the lower measurement base 224 is exposed, which is convenient for inserting the detection card 1.
