Patent number: 12264470Abstract: The invention provides a water supply system of a toilet tank, comprising a trigger switch, a water inlet pipe set and a drain pipe set. The inlet pipe set comprises a divergent water channel and a valve. The drain pipe set comprises a main drainpipe, an overflow manifold, a drain valve, and a drain valve actuator. The drain valve comprises a water stoppage valve cover and a rubber valve seat comprising a baffle which has a first state not affected by water entering the main drainpipe, and a second state affected by the water entering the main drainpipe. The main drainpipe communicates with the overflow manifold in the first state; and the junction between the main drainpipe and the overflow manifold is blocked by the baffle in the second state. The actuator drives the water stoppage valve cover when the channel is communicated.Type: GrantFiled: December 30, 2022Date of Patent: April 1, 2025Assignee: HOKWANG INDUSTRIES CO., LTD.Inventor: Chin-Chan Hsu

Patent number: 12146309Abstract: A quick water discharging device of a toilet tank, including a water discharging structure including a main pipe and an overflow manifold communicating with an inner space of the main pipe; and a water stoppage structure including a rubber valve seat located at an end of the main pipe, and a water stoppage valve pivotally connected to the overflow manifold and fitted with the rubber valve seat. The main pipe includes a pipe body, the inclined surface, and a communication hole communicating with the overflow manifold. The rubber valve seat includes a seat body, an opening communicating with the main pipe, and at least one baffle extending from the seat body to the main pipe. The baffle is close to an inner wall of the main pipe, faces the communication hole, and covers at least 50% of an area of the communication hole.Type: GrantFiled: December 30, 2022Date of Patent: November 19, 2024Assignee: HOKWANG INDUSTRIES CO., LTD.Inventor: Chin-Chan Hsu

Patent number: 10149576Abstract: An automatic liquid soap supplying system is provided with a plurality of soap dispensing main bodies for discharging a liquid soap, a plurality of soap dispensing components to be respectively connected to the soap dispensing main bodies, a liquid soap filling tank connected to each soap dispensing component, a mounting component provided with a photo display area of necessity for supplying liquid soap, as well as a control unit. In this case, a differential hydrostatic pressure is formed between the liquid soap filling tank and the soap dispensing component, whereby the liquid soap is filled into the soap dispensing component automatically from the liquid soap filling tank through the differential hydrostatic pressure. Moreover, the photo display area of necessity for supplying liquid soap is used to recognize whether supplement of soap is required, and air remained due to the supplement of soap is discharged via a exhaust valve.Type: GrantFiled: September 14, 2017Date of Patent: December 11, 2018Assignee: HOKWANG INDUSTRIES CO., LTD.Inventor: Chin-Chan Hsu

Patent number: 8342369Abstract: The present invention provides a pressing structure of a soap dispenser for adjusting an output amount of the soap by adjusting the distance of a pressing stroke thereof. The pressing structure includes a rejecting member, a driving device, and a moving member, wherein the driving device is connected to the moving member through a transmission mechanism, and the rejecting member includes a connecting portion linked with the moving member, and a pressing plate against a pressing head of a liquid container, characterized in that the rejecting member further includes a retractable portion used for adjusting the vertical distance between the connecting portion and the pressing plate. Accordingly, through adjusting the vertical distance by the retractable portion, the vertical moving distance of a pressing head of a liquid container achieved by the pressing plate can therefore be decided, so as to output a suitable amount of soap.Type: GrantFiled: October 29, 2009Date of Patent: January 1, 2013Assignee: Hokwang Industries Co., Ltd.Inventor: Chin-Chan Hsu
