5results about How to "Improve rinse quality" patented technology

This application discloses a water purifier and its flushing control method, relating to the technical field of water purifiers. The flushing control method for the water purifier includes: after the water purifier stops discharging water, checking at least one historical water discharge record; determining whether any historical water discharge record meets preset flushing conditions; ensuring a one-to-one correspondence between the preset flushing conditions and the historical water discharge record; and controlling the water purifier to enter the flushing state if historical water discharge record exists. Therefore, this application has the advantages of improving the flushing quality and water discharge quality of the water purifier, adapting to different usage locations or scenarios, and enhancing the user experience.

This utility model applies to the field of laboratory glassware cleaning, providing a digestion tube rinsing module. It includes a mounting plate and a housing with an opening at the top. A water pump and a water spray interface are installed at the bottom of the housing, with a nozzle extending through the top of the housing. A power unit and a transmission assembly are mounted on the mounting plate. The power unit provides power to rotate the output end of the transmission assembly, which is fitted with a digestion bottle mounting base. When the digestion bottle mounting base is rotated to a vertical position, the opening of the mounting base aligns with the position of the nozzle. This device, under the automatic control of an external controller, allows for unified regulation of the water pumps and valves connected to the water pump, water spray, and water injection interfaces, achieving coordinated operation of water injection, water spraying, and water pumping functions within the housing. This reduces the intensity of manual operation and improves the efficiency and quality of digestion tube rinsing.

The application discloses a metallographic flowing washing device, which solves the technical problem of unclean sample washing in the prior art. The device comprises a waste liquid tank, a height adjusting structure, an alcohol storage structure, a control valve and an illumination structure. The height adjusting structure is installed in the waste liquid tank, and the alcohol storage tank is installed on the height adjusting structure. The height adjusting structure is used for adjusting the vertical relative position of the alcohol storage tank and the waste liquid tank. The control valve is installed on the alcohol storage tank, and the valve port of the control valve is located in the range of the waste liquid tank. The illumination structure is arranged at intervals with the waste liquid tank, and the illumination structure comprises a light source and a resistor connected with the light source. The metallographic flowing washing device disclosed by the application realizes flowing alcohol washing of metallographic samples of different specifications through the combination of the waste liquid tank, the alcohol storage tank, the control valve, the height adjusting structure and the illumination structure, prevents the retention of impurities, facilitates the observation of the washing effect, recycles the washed alcohol and protects the environment.

The utility model relates to a visible flushing device for a separator, and relates to the technical field of gas production. The visible flushing device of the separator comprises a first supporting piece and a second supporting piece, the second supporting piece is rotationally connected with one end of the first supporting piece; the spraying assembly is installed at the end, away from the first supporting piece, of the second supporting piece and used for being communicated with a water pipe; the probe is fixed to the second supporting piece and used for shooting the spraying area of the spraying assembly; one side of the adjusting assembly is connected with the first supporting piece, the other side of the adjusting assembly is connected with the second supporting piece, and the adjusting assembly is used for adjusting the included angle between the first supporting piece and the second supporting piece. The internal environment of the separator can be shot through the probe, the included angle between the first supporting frame and the second supporting frame is correspondingly adjusted through the adjusting assembly, the spraying direction of the spraying assembly is adjusted, all areas in the separator can be conveniently flushed, and the flushing quality of the separator is improved.

This utility model discloses a post-treatment device for high-exchange macroporous weakly basic anion exchange resin, relating to the field of polymer post-treatment technology. The utility model includes an alkaline washing tank, a rinsing assembly, and a filter box. The rinsing assembly and filter box are located on one side of the alkaline washing tank. The alkaline washing tank includes an outer shell and an inner liner, with an end cap fixedly connected to the top of both the outer shell and the inner liner. A water cavity is formed between the outer shell and the inner liner. A water injection pipe is fixedly connected through the upper periphery of the outer shell. Two heating pipes are installed inside the water cavity. A storage box is installed inside the filter box, with a screening box fixedly connected to the bottom of the storage box. A hollow plate is installed above the storage box, and a nozzle is fixedly connected through the bottom of the hollow plate. This utility model achieves integrated resin post-treatment by setting up an alkaline washing tank, a rinsing assembly, and a filter box. Dust will not adhere during the rinsing process, and the resin can be more easily removed after post-treatment, accelerating the replacement of inorganic acids and silicate ions.
