3results about How to "Effectively remove" patented technology

This invention relates to a cleaning device, sample analyzer, and method for a dual-needle structure. The cleaning device includes a cleaning tank, a partition, a liquid outlet, and a drain outlet. The partition is positioned on one side of the cleaning tank, corresponding to the area between the two sampling needles. The liquid outlet is located on the other side of the cleaning tank and is used to spray cleaning fluid onto the outer walls of the two sampling needles. The drain outlet is located at the bottom of the cleaning tank to discharge the cleaning fluid after cleaning the sampling needles. The cleaning device provided by this invention can effectively remove residual liquid between the two needles, while also reducing the amount of liquid adhering to the outer walls of the needles or the risk of liquid adhering to the outer walls, effectively preventing the risk of dilution of the test sample. The cleaning method provided by this invention allows for setting cleaning modes according to different levels of contamination in the test items, effectively improving the cleaning effect and saving water to a certain extent. The cleaning device and method provided by this invention, when applied to a sample analyzer, can effectively improve the quality of the analyzer and the user experience.

The invention relates to the technical field of machining, in particular to a method and device for machining grooves in the end face and the edges of a hard and brittle material structural body, according to the method, a rotary cutter is used for grinding and machining the grooves in the end face and the edges of the hard and brittle material structural body, and the thickness of the rotary cutter is the width T of the grooves. The characteristic that hard and brittle materials are difficult to machine is solved, the hard and brittle materials can be effectively ground away through the rotary cutter, large mechanical stress cannot be generated, the rotary cutter is suitable for treating high-hardness and brittle materials, and grooves can be directly machined in the end face and the edges of a structural body; grooves with different depths are obtained through accurate control according to different feeding depths and machining paths of the rotary cutter, the universality is high, the process adaptability is higher due to the flexibility, and the device is suitable for products of various specifications; the size of the rotary cutter determines the size of the final groove, so that the width and the depth of the groove can be accurately controlled, an additional finishing step or secondary machining is not needed, the technological process is reduced, and the production efficiency is improved; and automatic processing is easy to realize.
