Technical Field

[0001] The utility model relates to the technical field of etching solution preparation devices, and particularly relates to an etching solution preparation device. Background Technique

[0002] An etching solution preparation device is a device specifically used for preparing etching solutions. It can prepare specific etching solutions according to different etching requirements through precise formulations and mixing processes. Such a device usually includes multiple storage containers for storing various raw materials such as acids, alkalis, organic solvents, etc., as well as mixing, stirring, filtering and other units to ensure that the components of the etching solution are uniform and of high purity.

[0003] The utility model patent application document with the publication number of "CN218166802U" discloses a printed circuit board etching solution preparation device, which relates to the field of mixing technology and includes a beaker. A fixing plate is installed at the top of the beaker, and a stirring rod is rotatably connected to the bottom end of the fixing plate. Stirring blades are connected to the outer wall of the stirring rod. A plug rod is inserted into the stirring rod, and a plug block is connected to the bottom end of the plug rod. A sliding block is connected to the outer wall of the plug block, and a slideway for the sliding block to slide is opened on the inner wall of the stirring rod. The sliding block is inserted into the slideway. Through the design of the stirring rod and the stirring blades, the stirring radius is increased, the stirring range is expanded, and the stirring effect is improved, thereby improving the mixing efficiency of the raw materials. At the same time, a slideway, a plug rod, a plug block and a sliding block are provided, and the worker can pull the plug rod up and down to make the stirring blades rotate reciprocally, without frequently rotating the stirring rod, reducing the labor intensity of the worker.

[0004] The above-mentioned printed circuit board etching solution preparation device disclosed in the document has the following defects: This technical solution cannot clean the inner wall, resulting in the inner wall adhering to the etching solution during discharging, so that the discharging is not clean and needs to be frequently cleaned.

[0005] It can be seen from this that the existing printed circuit board etching solution preparation device does not have a good stirring component, and it is necessary to improve the existing deficiencies and provide an etching solution preparation device. Content of the Utility Model
