  • Patent number: 7900863
    Abstract: A retractable cable device having protecting function mainly comprises a housing, a spiral spring, a spool disk, an arresting system, and a communication cable. The spool disk pivoted on a shaft within the housing is wound by the communication cable. The spiral spring provides the spool disk with a reeling force to reel in the communication cable. The rotation of the spool disk flexibly controlled by the arresting system decides the protruding length of the communication cable. A swaying member installed on the spool disk is utilized to replace the conventional immovable clip for fixing the communication cable. Whereby, when the entire communication cable is drawn out, the communication cable at a second end of the swaying member presents a larger bent angle. Therefore, the communication cable is subjected to bending with less sharp degree, thence protecting the communication cable, especially for the core, by preventing it from damage.

  • Patent number: 7877822
    Abstract: A non-water lavatory flushing device consists of a electrical four-way valve, which one of its exit is connected with the exit of the side wall of the valley at the back of the toilet pan for collecting the feces. The three exits are connected with the central part of the toilet pan, feces collecting box and the flushing liquid collecting box through a feces dispersing pipe, a feces collecting pipe and a urine collecting pipe. The non-water lavatory flushing device of the invention uses a four-way valve to replace the feces dispersing pipe magnetic valve, feces collecting pipe magnetic valve and urine collecting pipe of the prior art. The dispersed feces liquid and urine in the feces dispersing pipe, feces collecting pipe and urine collecting pipe is controlled by the four-way valve respectively. Then the structure is simplified and the cost is decreased. Furthermore, as the four-way joint is cancelled, the problem of wrong flowing of the leaving liquid is solved.
