Abstract: A juice extracting cup used in a juice extractor comprises a cup body and a filter net. The cup body is hollow and has openings at two ends and several longitudinal ribs projected from inner wall. A supporting strip along the inner wall of the cup body is projected from the inner wall below the several ribs. The filter net is disposed inside the body cup, and several clip strips are projected at the bottom end of outer wall of the filter net. Several openings correspond to the several ribs between every two clip strips, and each of the several openings hosts the respective rib. The several clip strips are clipped between bottom ends of the several ribs and the supporting strip. The juice extracting cup used in the juice extractor according to the present invention can effectively prevent the filter net from falling off and thus the effect of juice extracting can be guaranteed.

Abstract: A sound effect sensing turntable for a digital music broadcaster includes a capacitive charge sensing plate able to independently detect the variation of charge. A signal transmission unit is disposed between the sensing plate and a control plate for transmitting signals and thus, on receiving a signal, the control plate will produce relative sound effect to be output. In operating, when a DJ's fingers slightly touch the turntable, the sensing plate will sense charge variation on the turntable and actuate the control plate to control corresponding sound effect. By detecting the variation of charge on the turntable for controlling sound effect, the mode of touching the turntable of this invention for producing sound effect is like that of conventionally controlling a vinyl record for controlling sound effect, getting rid of conventional defect of producing wrong sound effect due to assembly errors.

Abstract: A juicer having safety mechanism with its handle is disclosed, where the handle is used to buckle its cover. A contact switch is fixed in the body of the juicer and connected in series with a starting circuit of the juicer motor. As the handle buckles the cover, a moving element with a through hole is forced to move down, which enables the through hole to be aligned with a contact member of the contact switch. During the handle buckling the cover, the prop pillar is held to pass through the through hole of the moving element to reach the contact member of the contact switch for turning on the contact switch. On the other hand, if either the cover or the handle is not in place, the contact switch is in power disconnection. Accordingly, the objective of the safety protection can be truly fulfilled.

Abstract: A juicer structure is disclosed, which features a clutch fixed at the terminal of a driving unit to be connected with a blade turntable, where the connected media is made of plural tiers of joining surfaces. A radial rod is set up in the joining surface corresponding to each bead hole. A bead hole allows protrusion of curved side at one end of a rod. And each curved side of the rod is lodged in the corresponding embedding hole, which establishes a firm coupling between the blade turntable and the clutch. The clutch actually is a multiple-tier design, and joins the blade turntable in an axial coupling with the support by the rod, which substantially boosts the stability of the joining with the blade turntable.
