[0030] How it works

[0031] The utility model discloses an exhaust device for tin-copper-nickel alloy electroplating with a cooling function. When in use, the air pump 1 is turned on by a control device, and the exhaust hood is moved to the top of the tin-copper-nickel alloy electroplating pool by a handle.
