Abstract: A heater structure includes a heater body including a burner connected to a valve switch. A pilot fire assembly is covered by a protective cover that has ventilation holes. A switch unit includes an ignition switch, a shut-down switch, an ignition operator, and a shut-down operator. The ignition operator and the shut-down operator are structured to provide a swingable arrangement. The ignition operator may be operated to contact and press the fuel gas valve rod and the ignition switch to open the valve switch for supply fuel gas to the burner and to activate an ignition circuit to cause successive shootings of an ignition pin of the pilot fire assembly to set a flame on the burner. The shut-down operator is operated to contact and press the shut-down switch, so as to cut off a signal of the thermocouple and thus cut off the supply of the fuel gas.

Abstract: A quick removal fitting includes a female coupling part, a male coupling part, and a retention clip. The female coupling part includes a flange. The male coupling part (which can be for example a water pipe) has an end forming a divergent opening and includes a protrusion ring mounted thereto and a movable ring movably arranged thereon. The retention clip is made of an elastic material and is selectively set to clamp, in a removable manner, the flange of the female coupling part and the movable ring together. The retention clip that is set to removably clamp the female coupling part and the male coupling part together at a connection therebetween helps simplify assembly/disassembly and replacement. The movable ring that is movably arranged on the male coupling part helps eliminate a mounting operation involving welding.
