Abstract: Disclosed is an electronic glow stick comprising a stick body which is a tubular body, at least one handle in a plugged connection with an end of the stick body, a battery pack which is disposed in the handle and connected with the handle in a detachable way, and a light emitting element which is connected with the battery pack and electrically connected with batteries in the battery pack. The batteries can charge the light emitting element, and the light emitting element can project light in the stick body such that the stick body glows. The electronic glow stick has advantages of simple structure, low cost and high durability because of no circuit board; additionally, damaged parts can be exchanged instead of replacing the whole unit, thus effectively saving use cost; moreover, the handle is detachably connected with the stick body, so the whole glow stick has diversified structures.

Abstract: Disclosed is a luminous necklace structure. The present invention adopts the following technical solution: A luminous necklace structure, comprising a battery case; a chain rope with both ends connected with the battery case; at least one pendant connected with the chain rope; so that the battery case can supply power to the chain rope and make the pendant luminous. The chain rope comprises two conductive wires which are fixedly connected in parallel. The battery case comprises a casing and a power supply assembly provided in the casing, with two ends of the two conductive wires connected to the casing and the conductive wires electrically connected to the power supply assembly.

Abstract: The present invention discloses a multi-functional battery box, belonging to the field of power supply devices; a multi-functional battery box, comprising: a case, having an accommodating cavity; a printed circuit board, located in the accommodating cavity and permanently connected with the case; a power source, located in the accommodating cavity and in contact with the printed circuit board; an electro-acoustic transducer, permanently arranged on the printed circuit board and electrically connected with the printed circuit board; a spring piece, arranged on the case and in contact with the printed circuit board; a change-over switch, flexibly connected with the printed circuit board; the present invention has two switching modes that can be flexibly switched, making the battery box easier and more flexible to use, reducing the loss to the switch and prolonging the life of the battery box.

Abstract: A projection lamp with a rolling lamp effect includes an outer housing, which is an inner hollow structure with an opening; a lampshade, which is a light transmitting structure, covering the opening of the outer housing and fixedly connected to the outer housing; a light emitting module, which is fixed in the outer housing through a fixed shaft; and a light condensing ball lens, disposed in the outer housing. A shaft sleeve is disposed on the outer surface of the light condensing ball lens in a protruding way; the light emitting module is positioned in the light condensing ball lens and is fixed in the shaft sleeve; the motor, which is fixedly disposed in the outer housing, is in a transmission connection with the shaft sleeve, and the motor can drive the light condensing ball lens to rotate around the axis of the fixed shaft in the outer housing.
