Abstract: A steam cleaner comprises a water reservoir; a heater including a supply pipeline, a first steam pipeline spaced from the supply pipeline, and a sediment catching space between the supply pipeline and the first steam pipeline; a steam chamber with a portion of the first steam pipeline disposed therein; and a nozzle including a second steam pipeline partially disposed in the steam chamber and spaced from the first steam pipeline. Water is drawn out of the water reservoir to the heater for heating, steam is generated in the heater and flows out of the supply pipeline into the first steam pipeline through the sediment catching space with solid particles therein being deposited in the sediment catching space to form sediment and remaining steam flowing into the second steam pipeline through the steam chamber, and the steam is shot out from the nozzle. The invention prevents sediment from blocking the nozzle.

Abstract: A low voltage bobbin includes a core portion, a base portion, a plurality of insertion pins formed on an outer wall of the base portion, and a wire winding rod axially extending from each of the insertion pin. The thickness of portion of the outer wall of the base portion that is corresponding to each of the plurality of insertion pins is thinned down, each of the wire winding rod has a descending diameter from a root end to a free distal end of the wire winding rod.

Abstract: A minimized casing structure of a flyback transformer includes a base, a chamber, a guiding tube, and a rod. The chamber is formed on a side of the top surface of the base, while a recess is formed on the other side. A first extension platform is formed at front side of the base, and between the first extension platform and the front side of the base a plurality of enhancement ribs are provided. The first extension platform is connected with a second extension platform, wherein the rod is formed on the second extension platform extending from a bottom face of the second extension platform, and at least one enhancement rib is formed between the rod and the bottom face of the second extension platform.

Abstract: An oven includes a rear wall plate, a hot current device combined with the rear wall plate. The hot current device consists of a fan disc, a separating plate, two fans, and a rotating power unit having a motor and a motor frame. The two fans are rotated by the motor to blow hot air in a chamber of the oven to be sucked in a space between the fan disc and the separating plate and then exhausted out of the space into the chamber back through exhausting holes of the fan disc, and circulating around in the chamber because of the exhausting holes arranged in a radiating condition.

Abstract: A roaster oven with whirlpool circulation comprising an oven housing and a whirlpool circulation device, the oven housing having two heating tubes for heating up air therein, an air inlet and two air outlets in a front wall, the whirlpool circulation device having a fan, a fan housing and a power source, the fan positioned in the fan housing to be rotated by a motor in the power source to blow air in the fan housing, the fan housing having two whirlpool circulating tubes bent backward extending from the fan housing to lead hot air from the oven housing through the air net into the fan housing and then through the air outlets of the oven housing and into the oven housing to circulate as a whirlpool around an article placed in the roast chamber, for thorough and even roasting.
