Abstract: An energy exchanging apparatus is constructed to include an energy source adapted for providing/delivering energy, a shell provided around the energy source and adapted for delivering a fluid to make an energy exchanging action with the energy source, and a spiral member provided inside the shell and spirally extended around the periphery of the energy source and defining a spiral flow path for guiding the fluid spirally over the periphery of the energy source.

Abstract: An aerial valve for controlling gas flux comprises a vessel connected between an air exit and an air entrance of a gas source and having an axial larger cavity; an inner container arranged and fixed in the axial larger cavity and having an axial middle cavity and two ventages corresponding to the air exit and the air entrance; an adjusting means having a hollow portion arranged in the axial middle cavity and having an air inlet, a smaller air outlet and a larger air outlet corresponding to the ventages, the two air outlets being communicated with the air inlet. The inner container is placed between the vessel and the adjusting means and is made of leakageproof material. The adjusting means is coaxially and rotably assembled with the vessel on bottom thereof.

Abstract: A safety valve apparatus is arranged on a water inlet of a vapor heater and comprises a cover, a clutch unit and a resilient unit. The clutch unit comprises an upper disk and a stage detachably assembled with the upper disk. The resilient unit is arranged between the cover and the upper disk such that the upper disk is normally rotated with the cover. The upper disk has a downward extending cylinder looped by a spring and having a movable cap on one distal end thereof. The movable cap normally seals an outlet below the stage by the resilient force of the spring.

Abstract: A vapor cleaner comprises a main body, a heating stove, a conduit and a plurality of brushes. The main body is a hollow casing with two compartments therein, and has an accommodation groove on bottom thereof. The heating stove is fixedly arranged in one compartment and the brushes are placed in another compartment. The conduit has one end screwed to a nozzle of the heating stove and another end connected to a handle. The handle can be locked in the accommodation groove. The brushes not assembled to the handle are stored in another compartment; the handle and the brush assembled therein are locked into the accommodation groove.

Abstract: A vapor cleaner comprises a main body, a water tank, an electric heater and a pressure valve. The pressure valve is composed of a baffle plate, a nozzle, a piston and a spring. The provision of the pressure valve can retard the instant ejection of vapor until the vapor pressure reaches a predetermined value. Therefore, the vapor can be smoothly sprayed with larger pressure and temperature. The droplet is smaller and the vaporization is uniformly generated.

Abstract: A retaining structure for brush of vapor cleaner comprises a sheath pipe, a coupling means, a duct, a rotation means, a plurality of connection units, an upper cover and a bottom plate. The sheath pipe is connected to the duct; one end of the sheath pipe is connected to the rotation means. The rotation means is assembled with the upper cover. The connection units are arranged on the upper cover. The upper cover is assembled with the bottom plate. The vapor cleaner generates high-temperature vapor, and the vapor is sent to the bottom plate for emission through the duct. The connection units can be assembled with de-dirt paper or wipe for cleaning.

Abstract: A waterproof button switch has a switch mount and a base. The switch mount has a stage and a cap arranged thereon. The base has a hole with an inner surface. The cap has relative movement with the inner surface and also has relative movement with the stage. The cap has a recess with rectangular cross-section on a circumference thereof and a leakage proof ring is embedded into the recess. The leakage proof ring has an inner semi-segment and an outer semi-segment. The inner semi-segment has rectangular cross-section for fitting into the recess. The outer semi-segment is slantingly extended from an outer surface of the inner semi-segment and has a triangular cross-section, the outer semi-segment comprises a tail having surface contact with the inner surface of the hole.

Abstract: A vaporization apparatus comprises a cover, a base, and a heating pipe. The base is arranged below the cover and assembled integrally with the cover. The base has an accommodation space therein and a heat-conducting fin plate is provided in the accommodation space. The heat-conducting fin plate has a bottom side connected to a bottom side of the base and the heating pipe is arranged below the base. The heating pipe is completely or partially overlapped with the bottom side of the heat-conducting fin plate. The heat energy generated by the heating pipe can be concentrated to the heat-conducting fin plate and water in the accommodation space can be rapidly heated.
