This invention discloses a method for testing the strength of engineering plastics. It addresses the problem of over-reliance on operator subjective experience and inconsistent judgment standards in determining the ultimate force of engineering plastics. This invention quantifies the difference between bending force and inversion stress, sets a standardized error threshold, and accurately determines whether the two sets of force values ​​exhibit an arithmetic progression. This objectively distinguishes between valid and abnormal detections from a data perspective. For abnormal detections, a retest signal can be directly generated to quickly locate problems such as loose clamping or excessive force loss, reducing invalid detections. For normal test data, a progressive logic of difference range prediction and inversion stress range verification accurately pinpoints the ultimate force of the engineering plastic, clearly distinguishing between the normal buffer deformation stage, the stage of buffer elasticity depletion and synchronous change, and the critical fracture large bending stage.

This application relates to an electrolytic cell for screen printing stencils, belonging to the field of screen printing stencil technology. It includes a cell body with an inlet pipe and an outlet pipe. Multiple limiting plates are fixed to both sides of the inner wall of the cell body, and the limiting plates are vertically arranged. The space between adjacent limiting plates is for the screen printing stencil to enter. Each limiting plate has a through-hole for installation. Two limiting rods pass through the cell body, passing through positioning holes in the screen printing stencil and into the installation slots. At least two sets of installation slots are arranged vertically. The side wall of the cell body has through holes for the limiting rods to pass through. The technical advantages of this application are: high stability of the screen printing stencil after installation, no contact between adjacent screen printing stencils, and full contact between the screen and electrolyte; the method of picking up and putting in screen printing stencils one by one facilitates operation and has good applicability to screen printing stencils of different sizes.

This invention belongs to the field of medical testing equipment technology, specifically an intelligent anti-loosening chest breathing effort testing device with a magnetic quick-change probe. The proposed solution includes: a magnetic suction mechanism, one end of which is fitted with a sleeve tube. This mechanism enables quick magnetic attachment and disassembly of the probe to the device body, and forms an intelligent anti-loosening seal through the magnetic attraction and elastic structure, preventing the probe from falling off and leakage of the patient's exhaled air during testing; and a testing mechanism, with both ends fixedly mounted on the other ends of the two magnetic suction mechanisms. This invention utilizes a Tesla valve structure composed of a right side plate, a left side plate, and a mounting plate to create an asymmetric resistance airflow channel. During inhalation, the airflow passes through quickly; during exhalation, the airflow is guided by a triangular diverter and flows along the surfaces of the right and left side plates, creating a counter-impact. This counter-impact significantly increases exhalation resistance, ensuring the required airflow power for testing while greatly reducing the respiratory burden on the tester.

This utility model relates to a dishwasher, including a tub with a washing chamber inside; a water tank located below the tub, the water tank and the tub being connected by a return pipe that allows water to flow from the water tank towards the tub; a waste basket located at the bottom of the tub, the top of the waste basket being open as a water inlet located in the washing chamber, and the waste basket extending into the water tank, the waste basket having drainage holes on its side and bottom walls; a cover plate movably mounted on the top of the waste basket, the cover plate being driven and connected to a drive mechanism to open or close the waste basket's water inlet; the dishwasher also includes a water inlet pipe for supplying water to the tub, the water inlet pipe being connected to the return pipe. When it is not necessary to filter the residue in the washing water, and only the washing water is needed to rinse the dishes, the cover plate can be used to close the waste basket's water inlet, so that the washing water will not flow through the waste basket or come into contact with the residue in the waste basket, avoiding contamination of the washing water by the residue.
