Abstract: A watch winder case is disclosed to include two opposite end plates connected to each other through two first support bars and two second support bars. Two first side plates are respectively abutted and inserted between one of the two first support bars and one of the two second support bars, and a second side plate is abutted and inserted between the two second support bars. Thus, the structural strength and structural stability of the watch winder case can be enhanced.

Abstract: A watch winder includes a housing, a power supply disposed in the housing, a transmitter coil mounted at one side of the housing and electrically connected with a circuit board of the power supply, and a receiver coil mounted at another side of the housing and electrically connected with a circuit board of the power supply. The fist coil can be actuated by the power supply to transmit a signal, and the receiver coil can be used to receive a signal and convert the signal into an electrical current that can be transmitted to the circuit board for charging the power supply. Therefore, the electrical energy of the watch winder can be wireless transmitted through a non-contact interface.

Abstract: An impact sensor for installation in a moving machine to detect an impact includes first and second electrically conductive strip and an insulative layer sandwiched therebetween. The first electrically conductive strip has at least one electrically conductive member facing but insulatively separated by the insulative layer from at least one electrically conductive member of the second electrically conductive strip. The insulative layer has a plurality of through holes, through at least one of which the electrically conductive member of the first electrically conductive strip and the electrically conductive member of the second electrically conductive strip are electrically contactable with each other when the second electrically conductive strip deforms under impact.

Abstract: A fountain lamp includes a housing having a bottom inlet, a pump unit mounted inside the housing for pumping a fluid from the inlet into a delivery pipeline, a light emitting device mounted in the housing for controllably emitting light out of the housing, a control unit for controllably driving the pump unit and the light emitting device, and a shifting unit having a base mounted in the housing and having a through hole connected to the delivery pipeline and a spray-pattern dial rotatably mounted in the base. The spray-pattern dial has multiple chambers, multiple guide holes respectively connected to the chambers and selectively set in communication with the through hole, and multiple sets of outlets respectively connected to the chambers for selectively exit of the fluid from the chambers and the housing for different fluid spray patterns.

Abstract: A portable ultraviolet (UV) germicidal lamp is disclosed, which is characterized by a safety switch configured inside a housing of the UV germicidal lamp that is electrically connected to a control circuit for controlling the UV germicidal lamp to be turned on and directing the same to emanate a UV ray downwardly while the UV germicidal lamp is positioned at a normal condition, and controlling the UV germicidal lamp to be turned off as the safety switch is being activated while the housing of the UV germicidal lamp is inclined by a specific angle and thus preventing the UV ray from shining upward.
