Abstract: A fitter kettle structure contains: a container, a lid, and a filtering device. The container includes an opening, an outlet, and a grip handle. The lid rotatably covers the opening and includes a surround section, multiple guiding holes, and a through hole. The filtering device includes a first filter unit, a connection rod, and a second filter unit. The first filter unit is housed in the container, the connection rod inserts in the through hole and its lower end inserts into the container and connects with the first filter unit, and an upper of the connection rod extends out of the container. The second filter unit fits with the surround section so as to form an isolation space in the surround section, and the second filter unit includes an aperture and a leak-proof ring surrounding the second filter unit and matingly contacting with the container.

Abstract: A filtered connector is mounted on a casing and includes a connection port and a filter board. An electrode plate mounted on one end of the connection port and electrically isolated from the casing is securely mounted through a through hole of the casing. The filter board has a circuit board assembly, multiple grounding spring plates and multiple filtering capacitors. The circuit board assembly has a slot to be mounted through by the electrode plate. The grounding spring plates are mounted on a surface of the circuit board assembly and electrically contact the casing. The filtering capacitors are electrically connected between the electrode plate and the grounding spring plates. As the filter board is not mounted inside the connection port, only the filter board is to be mounted without replacing the connection port, thereby lowering users' expense in installation of the filter board.
