Abstract: The present invention relates to a voltage converter, which uses an inductor coupled between a power supply and a reference voltage for providing a supply voltage. A plurality of output capacitors are coupled to both sides of the inductor, respectively, and receive the supply voltage for producing a positive voltage and a negative voltage. A plurality of output switches are coupled to both sides of the inductor, respectively, and control the inductor to charge the plurality of output capacitors. A feedback control circuit produces a control signal according to the positive and negative voltages for controlling the plurality of output switches. Thereby, the present invention can produce positive and negative voltage by means of the inductor. Accordingly, the voltage converter according to the present invention avoids usage of multiple inductors and capacitors in producing voltages with different levels, and thus reducing the circuit area as well as the manufacturing cost.

Abstract: A draining device is disposed within a drain port, which is defined by an upper end of a drain pipe embedded in the ground at an elevation below the ground surface. The draining device includes a tubular base member which has an open upper end, a closed lower end, a bottom wall, and a peripheral wall that extends between the upper and lower ends and that is formed with a plurality of drain openings. A water guiding tube is attached within the base member, and extends into the peripheral wall of the base member. The drain openings of the base member are located around the water guiding tube at an elevation above a lower end of the water guiding tube. The water guiding tube has open upper and lower ends, and is capable of guiding water from the upper end of the base member to the bottom wall of the base member. When water accumulates in a lower end portion of the base member, the water surface thereof is above the lower end of the water guiding tube so as to isolate air in the water guiding tube from air in the drain pipe, thereby preventing insects in the drain pipe from accessing the water guiding tube.

Abstract translation: 排水装置设置在排水口内，该排水口由位于地面下方的高度处埋在地下的排水管的上端限定。 排水装置包括管状基座构件，其具有敞开的上端，封闭的下端，底壁和在上端和下端之间延伸并且形成有多个排水开口的周壁。 引导管附接在基座部件内，并延伸到基部部件的周壁。 基部构件的排水口位于导水管的上方，位于导水管下端的上方。 导水管具有敞开的上端和下端，并且能够将水从基部构件的上端引导到基部构件的底壁。 当水积聚在底座部件的下端部时，其水面高于导水管的下端，从而将导水管中的空气与排水管内的空气隔离，从而防止排水管中的昆虫 管道进入导水管。
