Abstract: A wheel device applied to a mouse includes a base, a wheel module, a sheltering component and an optical detecting module. The base has a holder. The wheel module is disposed on the base and includes a roller and a wheel. The roller includes a rolling surface, an axle and a plurality of rib structures. The axle is rotatably disposed on the holder in an axle direction. The rib structures are disposed inside the rolling surface. The wheel is disposed on the rolling surface of the roller. The sheltering component includes light sheltering areas and light penetrating areas disposed on the roller or the wheel and around the axle direction. Each light sheltering area is perpendicular to the axle. The optical detecting module has an optical emitter and an optical receiver. The optical receiver is adapted to receive an optical signal emitted by the optical emitter.

Abstract: The present invention relates to a mouse, including a base, a cover plate provided with a hole, a circuit board, a button switch, an elastic cover, and an upper cover. The cover plate covers the base, and the circuit board is disposed on the base and located between the base and the cover plate. The button switch is disposed on the circuit board. The elastic cover covers the button switch, and extends into the hole together with the button switch, so as to prevent the button switch from being exposed out of the hole. The upper cover covers the cover plate, and the upper cover is capable of oscillating relative to the cover plate to abut against the elastic cover, so as to trigger the button switch.

Abstract: The present invention provides a mouse, including a mouse body, a button input component, and an idle stroke eliminating part. The button input component includes a button sensing element and a pressing member. The button sensing element is installed in the mouse body. The pressing member covers the outside of the mouse body, and the pressing member includes a connecting pole, where the connecting pole is inserted into the mouse body to abut against the button sensing element. The idle stroke eliminating part is disposed outside the mouse body, and the idle stroke eliminating part includes a pivot and an interference member. The pivot is pivotally connected to the mouse body; and the interference member is crimped on an upper surface of the mouse body, so that an idle stroke is eliminated.

Abstract: The present invention provides a mouse device, including a body, a circuit board, and a plurality of weight sensing units. The weight sensing units are configured to measure weights of counterweight blocks accommodated in the plurality of accommodating parts of the body. A processing unit of the circuit board is connected to the weight sensing units and is configured to generate and output a weight sensing signal according to the measurement result of the weight sensing units.

Abstract: The present invention provides a waterproof keyboard, including a keypad and a plurality of keys passing through the keypad. The keypad includes a compressive waterproof layer, a plate structure, and a plurality of through-holes, the compressive waterproof layer covering the plate structure, and the through-hole passing through the compressive waterproof layer and the plate structure. Each of the keys passes through one of the through-holes, and the compressive waterproof layer and the plate structure are clamped by means of a slot that is formed on a lateral surface of the key, to enable the key to be sealed with the compressive waterproof layer to form a sealed layer, so as to achieve the waterproof effect.

Abstract: A protecting mechanism for a blood sampling device contains: a trigger unit and a switching assembly. The trigger unit includes a lancet holder, a triggering shaft, and a resilient element. The lancet holder has a launching portion, a first outer protrusion, a through orifice, and a first inner shoulder, wherein a bottom end of the triggering shaft moves in the through hole, and the triggering shaft has a first outer shoulder for engaging with the first inner shoulder of lancet holder, the resilient element is fitted with the triggering shaft and abuts against the lancet holder by ways of its bottom end. The switching assembly includes a fixing jacket having an abutting portion, a rotating tube having a first inner protrusion and two opposite second inner protrusions, and a driving sheath having two stopping sets, wherein each stopping set has two second outer protrusions.
