Abstract:
A cigarette box includes a box body, a flip-top lid, and a cover. The box body is adapted to receive cigarette sticks therein. The lid is connected pivotally to the box body, and has a top portion formed with an opening that has a size sufficient to permit removal of no more than one of the cigarette sticks from the box body. The cover has a size corresponding to that of the opening, and has a peripheral edge that includes at least one tearable section connected to the top portion of the lid by a weakened seam such that the cover can be torn from the lid at the weakened seam to uncover the opening.
Abstract:
A circular loom includes an endless raceway assembly and a shuttle sliding along the raceway assembly. The raceway assembly includes an upper ring plate, a lower ring plate, and a rod mechanism interposed between the upper and lower ring plates. The rod mechanism includes a row of outer guide rod units interconnecting the upper and lower ring plates, and a row of inner guide rod units aligned respectively and radially with the outer guide rod units so as to define a confining space therebetween. Each of the inner guide rod units includes an upper inner rod section secured to the upper ring plate, and a lower inner rod section secured to the lower ring plate so as to define an accommodating space between the upper and lower inner rod sections. The shuttle includes a shuttle body, a horizontal guide plate extending outwardly from the shuttle body through the accommodating spaces of the inner guide rod units, a vertical guide plate secured to a radial outer end of the horizontal guide plate, and two sliding bodies connected respectively to upper and lower portions of the vertical guide plate. The sliding body has two vertical side walls slidable respectively on the inner and outer guide rod units. The upper ring plate has a removable portion which allows the shuttle to be put into the confining spaces.
Abstract:
A propulsion device includes a cylinder body, a first set of blades, a second set of blades, a first transmission shaft, a second transmission shaft, a power gear box and an accelerator. The first set of blades and the second set of blades are disposed in an airflow channel of the cylinder body. The first transmission shaft is connected to the first set of blades and the second transmission shaft is connected to the second set of blades. The first transmission shaft and the second transmission shaft are interconnected by the accelerator. The first set of blades has a first rotation speed, and the accelerator causes the second set of blades to have a second rotation speed. The second rotation speed is greater than the first rotation speed to increase the propulsion force.
Abstract:
This invention provides a power supply comprising a mother board, a first socket, and a DC-DC converter module. The mother board comprises a transformer operative for transforming an input power into a first AC output power and a filter operative for receiving the first AC output power and filtering the first AC output power into a first DC output power. The first socket is mounted on the mother board and electrically coupled to a circuitry of the mother board by way of at least one conductor terminal operative for providing the first DC output power. The DC-DC converter module mounted on a printed circuit board electrically coupled to the mother board comprises a DC-DC converter operative for receiving the first DC output power and converting the first DC output power into a second DC output power and a third DC output power and a second socket operative for providing the second DC output power and the third DC output power by means of a conductive path of the printed circuit board. There are several advantages including the reduction of the use of the conductive wires, the improvement of the efficiency of the power supply, the simplicity of the circuitry of the power supply, and the easy replacement of the broken component because the DC-DC converter module is mounted on an individual printed circuit board different from the mother board.
Abstract:
An unmanned aerial device having cleaning function includes a fuselage, a washing assembly and two propulsion assemblies. The washing assembly is disposed at a head of the fuselage. The propulsion assemblies are connected to two opposite sides of the fuselage. The two opposite sides are connected to the head. The propulsion assemblies each have an axial direction, and the axial direction is parallel to a direction from a bottom of the fuselage to a top of the fuselage.
Abstract:
A propulsion device includes a propulsion body and a diversion assembly. The propulsion body includes a propulsion system and a housing accommodating the propulsion system. The housing has an air-intake opening and an air-discharge opening respectively on two opposite sides of the propulsion system. The diversion assembly includes first and second diversion annular sheets. The first diversion annular sheet is disposed outside the air-discharge opening of the housing and having a surrounding center. The first diversion annular sheet is swung relative to the air discharge opening by a first axis passing through the surrounding center. The second diversion annular sheet is disposed outside the air-discharge opening of the housing and concentrically disposed with the first diversion annular sheet. The second diversion annular sheet is swung relative to the air-discharge opening by a second axis passing through the surrounding center, and first axis intersects the second axis.
Abstract:
A lightweight flying vehicle includes a carrier body, at least two fan-tube propulsion devices, two steering devices and a flight wing. The fan-tube propulsion devices are respectively disposed at two opposite sides of the carrier body and have a sufficient propulsion force. The steering device is disposed on a moving line of the airflow discharged from the fan-tube propulsion devices and is configured to change a direction of the airflow discharged from the air discharge opening, so that the lightweight flying vehicle is in a high-speed flight mode. The flight wing can provide a lift power in the high-speed flight mode.
