Abstract: An underneath large-capacity single-gas-pump foam generating device includes a liquid replenishment mechanism and a foam generating mechanism. The liquid replenishment mechanism includes a liquid replenishment groove and a liquid replenishment bottle. The liquid replenishment bottle has a bottle opening sleeved in the liquid replenishment groove. The foam generating mechanism includes a gas supply pump unit, a gas mixing groove cavity, a gas-liquid mixing structure, a gas inlet and a vent valve structure. A lower portion of the gas mixing groove cavity is communicated with a lower portion of the liquid replenishment groove, a liquid replenishment one-way valve is arranged between the gas mixing groove cavity and the liquid replenishment groove. The gas-liquid mixing structure is provided with a liquid outlet channel, a gas outlet channel and a mixing channel, an inlet end of the liquid outlet channel extends downwardly into a bottom portion of the gas mixing groove cavity.

Abstract: A leakproof gas-liquid mixing pump has a lower shell body, a pressing member and an upper shell body, the lower shell body has a liquid channel part and an outer shell part, the pressing member has a pressing part, a liquid guiding part and a first spring, the upper shell body surrounds the pressing member and is connected to the outer shell part and the liquid container. The leakproof gas-liquid mixing pump solves the problem that the gas-liquid mixing pump of the state of the art will leak when used upside down.

Abstract: A paper dispenser includes a base, paper dispensing portion and cover. The paper dispensing portion has two support members and a paper dispensing unit. The paper dispensing unit has an auxiliary roller, paper dispensing roller, swing unit and paper dispensing cutter disposed at the swing unit. The paper dispensing cutter swings between the inside and outside of a receiving groove of the paper dispensing roller. The support members each have a roll resilient positioning unit, arcuate pivotal connection unit and cam guide groove surrounding the pivotal connection unit and being closed. Two sides of the paper dispensing roller are pivotally disposed at one end of the pivotal connection unit. The guide unit is movably disposed at the cam guide groove. The cover is pivotally disposed at the base and has a paper discharge hole. The paper dispensing portion is disposed between the cover and base.

Abstract: A cleaning agent supply device includes a holder; a power unit disposed at the holder; a rotary driving unit disposed at the holder, connected to the power unit, and having a radian-adjustable fan-shaped light-blocking unit; a photosensitive counting unit disposed at the holder and adapted to sense the radian-adjustable fan-shaped light-blocking unit; a reciprocating squeezing unit disposed at the holder, connected to the rotary driving unit, and adapted to squeeze a cleaning agent pump reciprocatingly; and a count control unit disposed at the holder, electrically connected to the power unit and the photosensitive counting unit, and adapted to control the number of times the radian-adjustable fan-shaped light-blocking unit passes the photosensitive counting unit, thereby controlling the number of times of squeezing out a cleaning agent.
