Different etching liquids can be selected according to the different processes to be adopted, and the etching liquids need to be accurately prepared according to the formula. Most of the liquid preparation is completed in a container. For the configuration of concentrated sulfuric acid as the raw material of the etching liquid, due to its characteristics, not only the formula ratio needs to be controlled, but also the order of adding water needs to be considered. Therefore, most liquid dispensers are not suitable for all etching liquid configurations. Utility Model Content

[0006] The invention also comprises a stirring rod which is coaxially arranged in the pre-liquid preparation chamber and the mixing chamber, and stirring blades are arranged in the stirring rod corresponding to the pre-liquid preparation chamber and the mixing chamber.

[0012] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0013] The present application embodiment provides an etching liquid dispenser, such as Figure 1-Figure 3 As shown, it includes a pre-liquid preparation chamber 1 and a stirring rod 2.

[0014] A liquid inlet pipe 11 is provided at the top of the pre-liquid preparation chamber 1, a flow pipe 3 is provided at the bottom of the pre-liquid preparation chamber 1, the bottom of the flow pipe 3 is connected to the mixing chamber 4, a water inlet 42 is provided at the top of the mixing chamber 4, a discharge port 41 is provided at the bottom of the mixing chamber 4, and valves are provided on the flow pipe 3 and the discharge port 41.

[0015] The stirring rod 2 is coaxially arranged in the pre-liquid preparation chamber 1 and the mixing chamber 4 , and stirring blades are arranged in the stirring rod 2 corresponding to the pre-liquid preparation chamber 1 and the mixing chamber 4 .

[0016] When in use, the raw materials are injected into the pre-mixing liquid chamber 1 according to the proportion through the liquid inlet pipe 11, and the stirring rod 2 is rotated to mix the raw materials evenly. During the mixing process or in advance, water is injected into the mixing chamber 4 from the water inlet 42. After the raw materials are thoroughly mixed, the flow pipe 3 is opened to allow the mixed liquid in the pre-mixing liquid chamber 1 to flow into the mixing chamber 4. During this process, the stirring rod 2 can stop rotating or continue to rotate; as a preferred use method, during the process of the mixed liquid flowing into the mixing chamber 4, the stirring rod 2 keeps rotating continuously, which can not only make the mixed liquid entering the mixing chamber 4 quickly mix with water, but also prevent the mixed liquid inside the pre-mixing liquid chamber 1 from stratification or sedimentation. After mixing evenly, stop rotating the stirring rod 2, open the discharge port 41, and complete the discharge.

[0017] Specifically, a heating plate 5 is provided on the outer peripheral side of the mixing chamber 4 for heating the water in the mixing chamber 4 to meet the water temperature conditions required when the mixed liquid is mixed with water.

[0018] Specifically, a drain outlet 43 is provided on one side of the discharge port 41, and a valve is provided on the drain outlet 43. The discharge port 41 is provided with a filter screen for filtering impurities in the etching liquid, and the top surface of the filter screen is higher than the bottom surface inside the mixing chamber 4. When the entire device is cleaned, the impurities remaining on the filter screen of the discharge port 41 can also be taken away while cleaning, so that the cleaning water and the impurities are discharged from the drain outlet 43 together.

[0019] Specifically, an observation hole 12 is provided on the outer wall of the pre-liquid preparation chamber 1 for observing the mixing condition in the preparation chamber 1 to avoid affecting the accuracy of the next liquid preparation, or to inject hot air into the observation hole to dry the device after cleaning.

[0020] Specifically, the stirring blades on the stirring rod 2 in the pre-mixing liquid chamber 1 are arranged to be tilted downward. When the stirring rod 2 rotates, it rotates in the direction of its tilt, giving a guiding effect to the mixed liquid in the pre-mixing liquid chamber 1, so that the mixed liquid can be quickly and thoroughly discharged to the edge of the pre-mixing liquid chamber 1 under the action of centrifugal force, thereby facilitating the mixed liquid to smoothly enter the flow pipe 3, so that the mixed liquid can completely flow into the batching chamber 4, thereby preventing the mixed liquid from remaining inside the pre-mixing liquid chamber 1.

[0021] Specifically, a motor 6 is provided at the top of the pre-mixing liquid chamber 1 , and an output shaft of the motor 6 is connected to the top of the stirring rod 2 to drive the stirring rod 2 to rotate.

[0022] Specifically, a concentration detector 7 is installed at the bottom of the pre-liquid preparation chamber 1, and a PLC controller 8 is provided on the outside of the pre-liquid preparation chamber 1. A concentration display 81 is integrated on the PLC controller 8. The PLC controller 8 is connected to the concentration detector 7 and is used to detect the concentration of a raw material in the mixed liquid, which can be used to adjust the ratio and accurately prepare.

[0023] When applied, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
