Abstract: A coffee maker includes a valve mechanism having a micro switch, an electromagnetic valve, a magnetic covering board activated by the electromagnetic valve for opening or closing a powder path, and a spring interconnecting the covering board and the electromagnetic valve. A motor-driven grinding mechanism includes two ring-shaped outer grinding members having teeth facing each other, and a spring biased inner grinding member including a hollow feed rod with a lead screw formed thereon. A powder fineness adjusting mechanism includes an adjustment lever. In a powder fineness adjustment for producing coarse coffee powder, pivoting the lever toward one direction will pivot an abutment member and move the same outward to push one grinding member for increasing a space between the grinding members filled with coffee beans to be ground. Pivoting the lever toward the other direction will produce fine coffee powder.

Abstract: A safety valve mounted in a steam cleaner is provided. The safety valve comprises a cap assembly, an actuation assembly, and a lock assembly. A rotation of the cap is adapted to detach the cap assembly when the steam cleaner is not operating or steam pressure inside the steam cleaner has not reach a safety value since the legs of the clutch are engaged with the notches of the driving disk. Responsive to generated steam reaching the safety value, the steam passes through the valve to lift the pushing member for compressing both the actuating member and the spring and disengaging the legs from the notches prior to exiting the steam cleaner such that rotating the cap will not rotate the lock assembly.

Abstract: A coffee maker includes a housing and a brewing assembly. Pushing a handle leftward moves projections along slides in a direction for rising a cylindrical member until being stopped. A funnel-shaped member with a coffee bag placed therein can be slid along the rails toward the housing until being stopped. Pushing the handle rightward moves the projections in an opposite direction for lowering the cylindrical member until being stopped. The coffee bag is pressed by a clamping member and the funnel-shaped member. The coffee maker will supply hot water to an inflow opening such that hot water may then fall through a recess, a mesh element, and a cavity to pass through the coffee bag and proceeds to form coffee extract. The coffee extract may pass an outflow opening and a filter prior to flowing out of the coffee maker.

Abstract: A coffee maker comprises a height adjustment mechanism for accommodating mugs with different heights including an internal casing, a gear in the casing, a column secured to the brewing assembly and the casing, the column including a rack meshed the gear, a staged knob seat interconnected the casing and the housing, the knob seat including flutes around inner surface of an outer stage, a shaft inserted through the knob seat to connect the gear, a knob including a receptacle securely engaged head of the shaft, upper and lower recesses the receptacle disposed therebetween, and two push buttons each including a spring-biased trigger partially projected from the recess, and a ridge engaged a valley of the teeth. Pressing the triggers into the recesses until the ridges clear the flutes, and turning the knob and the shaft will rotate the gear to raise or lower the rack and the brewing assembly.

Abstract: The present invention relates to a barbecue device. The barbecue comprises two cooking plates wherein a first cooking plate comprises two hinge joints at both rear ends, each joint including an elliptical cavity, a shoulder on its inner wall, and a rib projected from the inner wall, and a second pivotal cooking plate comprises two arc rabbets corresponding to the hinge joint, each arc rabbet adapted to fit onto the joint and slide thereon; and an inverted U-shaped handle pivotably secured to the first cooking plate and comprising two rotation portions at its both ends, each rotation portion including a projecting pin inserted into the cavity, disposed at one end thereof, and being lengthwise slidable therein, and a projecting stop member being parallel to the pin. The hinge is adapted to adjust an angle between the cooking plates in response to different thickness of foodstuffs or the number of foodstuffs to be broiled.

Abstract: A coffee maker includes a liquid container. A handle assembly includes a seat placed on the container. A pan is placed in the seat. A spring-biased discharge control assembly and a check valve are mounted to the pan. A lid assembly is fitted on top of the seat. An elongate actuation assembly is hingedly connected to a rear of the lid assembly and includes a push button located intermediate the rear and a forward actuation member. Pressing the push button will lower the actuation member to press down the discharge control assembly and will form a gap for permitting coffee to flow out of the container by tilting the coffee maker. Releasing the push button will expand the spring to lift the discharge control assembly for closing the gap.

Abstract: A coffee making apparatus comprising a body, a cover, a T-shaped pipe and valve unit, a clamping unit resiliently secured to the cover, a rotation disc, a filter unit, a disc retainer threadedly secured to the cover, a housing fitted over the cover, and a knob rotatably fastening in the housing and the rotation disc. Placing a coffee bag in the filter unit, rotating the knob together with the rotation disc, and moving the clamping unit downward will press and fasten the coffee bag as hot water being supplied from the pipe and valve unit for mixing with the coffee bag. In the preparation process, steam accompanied hot water may flow back to a reservoir. Also, a distance between a cup of the filter unit and a base of the body is adapted to adjust by threadedly rotating the cup about a sleeve of the filter unit.
