摘要： A liquid pump capable of achieving pressure equilibrium includes a body, piston member, unidirectional input valve, unidirectional output valve, input inner-pipe, unidirectional gas-feeding hermetic-seal valve and input outer-pipe. The body has an input opening, output opening and piston opening. The piston member has a piston space communicating with the piston opening. The unidirectional input valve includes an input plug and input resilient element. The input plug abuts against the input opening. The unidirectional output valve includes an output plug and output resilient element. The output plug abuts against the output opening from outside. An input channel of the input inner-pipe communicates with the input opening. Direction of gas-flow between the unidirectional gas-feeding hermetic-seal valve and the input inner-pipe is opposite input direction of the input channel. The input outer-pipe has an input portion communicating with the input channel. A gas-feeding-channel is defined between a gas-feeding-portion and the input inner-pipe.

摘要： The paper dispensing device includes a main spindle, an axle, two end pieces, and a cutting member. The main spindle has a compartment. The axle is rotatably supported inside the compartment. The end pieces are positioned adjacent to the two ends of the axle, respectively. Each end piece has an eccentric opening through which an end of the axle is threaded. A ring groove is configured around the eccentric opening along an inner side of each end piece. The cutting member includes a blade, a cutter axle, two arms extended outward slantwise from the cutter axle's two ends, and two guiding elements at the arms' outer ends moveably housed in the ring grooves, respectively. As the main spindle spins, the cutting member rotates along with the main spindle and its blade is extended out or retracted into the compartment as the guiding elements move along the ring grooves.

摘要： A spray quantity adjustable foam/liquid dual-purpose distribution device includes a gas compressor, a first control valve, a liquid accumulator, a second control valve, and a foam generation device that are connected to each other. The gas compressor compresses gas to generate the pressurized gas that is fed into the first control valve to be further supplied into the liquid accumulator or the foam generation device. When the pressurized gas is supplied to the liquid accumulator, the internal pressure of the liquid accumulator is increased to force liquid contained in the liquid accumulator to be fed into the second control valve, which, once opened, allows the liquid to be supplied to the foam generation device, so that the pressurized gas and the liquid are mixed in the foam generation device to generate a foamed liquid that is discharged out through an egress opening.

摘要： A foam soap dispenser includes a motor, stirring unit, pump and container, where the motor is combined with and linked to the stirring unit and pump; an output tube is configured on the front end of the stirring unit; the pump has an elastic sleeve body, first and second tubes, where the second tube is in communication with the container inside which soap liquid is filled. The motor drives the stirring unit and pump to operate simultaneously after the motor is started, an elastic sleeve body of the pump is operated by the motor to contract and expand, allowing the second tube to extract the soap liquid from the container to the pump, and the soap liquid is then delivered to the stirring unit through the first tube. Finally, the rotation of the stirring gears allows the soap liquid to become foam, which is output through the output tube.

摘要： A fluid pump includes a press head portion, first and second unidirectional-valves, and extensible sleeve-pipe. Disposed in the press head portion, the first unidirectional-valve allows fluid to flow from its second end to its first end. The extensible sleeve-pipe includes a rebound element and outer and inner pipes which form a capacity-variable storage chamber. The inner pipe has a first end communicating with the first unidirectional-valve and a second end fitted to a first end of the outer pipe. The second unidirectional-valve allows the fluid to flow from its second end to its first end. The first end of the second unidirectional-valve communicates with the second end of the outer pipe. Upon contraction displacement of the inner pipe, the fluid flows from the storage chamber into the discharge passage via first unidirectional-valve. Upon expansion displacement of the inner pipe, the fluid flows into the storage chamber via second unidirectional-valve.

摘要： A liquid foam delivery device includes a pump proper, a linear transmission mechanism, a unidirectional input/output gas mechanism and a unidirectional input/output liquid mechanism. The pump proper has a rotating shaft. The linear transmission mechanism converts rotational motion output by the rotating shaft into linear reciprocating motion perpendicular to the rotating shaft. The unidirectional input/output gas mechanism admits gas into a gas inlet and discharge gas from a gas outlet in a direction perpendicular to the rotating shaft through the linear reciprocating motion of the linear transmission mechanism. The unidirectional input/output liquid mechanism delivers liquid admitted through a liquid inlet to a liquid outlet through the rotational motion output by the rotating shaft. The liquid foam delivery device delivers gas and liquid with only one pump proper and one rotating shaft to therefore minimize the required number of constituent components, achieve miniaturization, render assembly easy and cut cost.
