[0002] Sample filters for agricultural product testing are crucial tools for ensuring agricultural product safety. With the development of agricultural production and food processing technologies, problems such as pesticide residues, heavy metals, and microbial contamination in agricultural products are becoming increasingly prominent. Filters remove impurities and contaminants from samples using physical or chemical methods, ensuring the accuracy and reliability of test results. Modern filters utilize high-performance materials and advanced filtration technologies to effectively improve sample purity and meet the requirements of various testing standards. They are widely used in laboratories, food safety testing institutions, and agricultural production processes, providing vital support for protecting public health.

[0003] Existing sample filters for agricultural product testing mainly include membrane filters, fiber filters, and porous material filters. Membrane filters utilize microporous membrane technology to effectively remove bacteria, particulate matter, and large molecular contaminants, making them suitable for fine filtration of liquid samples. Fiber filters capture impurities through their fiber mesh structure, making them suitable for processing larger samples. Porous material filters utilize their porous structure and chemical adsorption properties to remove specific chemical contaminants. With the development of nanotechnology, nanofilters are also increasingly being applied to agricultural product testing, providing higher filtration precision and efficiency. The combination of these technologies improves the accuracy and reliability of agricultural product testing.

[0004] However, the aforementioned sample filters for agricultural product testing still have the following problems: the filter residue is inconvenient to clean and difficult to wash, causing trouble for subsequent operations. This increases the workload and may also affect the efficiency and accuracy of testing.

[0005] To address the aforementioned issues, a sample filter for agricultural product testing is proposed. Utility Model Content

[0016] 1. This utility model provides a sample filter for agricultural product testing. Firstly, it employs a barrel-shaped filter device with multiple built-in filter screens to achieve high-efficiency filtration. Simultaneously, multiple cleaning doors are designed on the side of the filter device for convenient cleaning of filter residue. Workers can easily remove the filter screens and residue simply by opening the cleaning doors, ensuring the filter's cleanliness and efficient operation. This design not only improves filtration efficiency but also greatly simplifies the cleaning process, reduces the complexity of manual operation, and enhances the overall efficiency and reliability of agricultural product testing.

[0017] 2. This utility model provides a sample filter for agricultural product testing. By setting a cleaning nozzle at the inlet of the filter device and equipping it with a small water pump and a water storage tank, it enables efficient cleaning of the filter device without disassembling the equipment.
