Description

Technical Field

[0001] The present application relates to a fan structure for a computer, and in particular to a parallel-connected luminous fan capable of quickly connecting a plurality of luminous fans of the same type together. Background Art

[0002] In the approved utility model application with certificate number M580203, a "luminous fan for computers with multiple connections" is proposed, which includes a main body, a fan blade is provided at the central position of the main body, and a luminous area is provided on the top of the main body at at least two sides of the fan blade. A power socket and a first connector are provided on one side of the main body, and a second connector is provided on the other side of the main body. The power socket is electrically connected to the first connector, the second connector, the fan blade and the luminous area respectively, so that after the power socket on one side of the main body is plugged in, the fan blade of the main body can be driven to rotate and the luminous area can be illuminated, and after the first connector of the main body is engaged with the second connector of the other body, the fan blade of the other body can be driven to rotate and the luminous area can be illuminated.

[0003] The first connector and the second connector of the above-mentioned known technology are both fixedly configured on the fan body. After a period of use, the electrodes are prone to oxidation or wear, which leads to poor contact or failure. At this time, the entire computer light-emitting fan must be replaced or discarded, which affects the service life of the light-emitting fan and causes waste.

[0004] In the utility model application with the approved certificate number M635856, a "luminous fan connection structure" is proposed, which includes a plurality of luminous fans and an external connector. The luminous fans are arranged adjacent to each other in a parallel manner, the blades of the luminous fans are arranged in a frame seat, the light guide ring is combined with the light-emitting module and is arranged outside the blades, the frame seat is provided with a fan circuit board and a buckle part, and the fan circuit board electrically connects the blades and the light-emitting module. The external connector includes a board seat and a connecting circuit board, the board seat includes a pair of hooks, the connecting circuit board includes a first and a second conductive pin, the board seat is straddled between adjacent luminous fans, the hooks buckle the buckle parts of adjacent luminous fans so that the first conductive pin is electrically connected to the fan circuit board, and the second conductive pin is electrically connected to another fan circuit board; thereby reducing the complexity of wiring and improving convenience during use. In addition to being used to transmit power, the external connector of the luminous fan connection structure of the above-mentioned known technology M635856 is also used in conjunction with a buckle seat to connect two adjacent luminous fans in parallel.

[0005] The main components for connecting two adjacent light-emitting fans in parallel are only a pair of hooks on the plate seat of the external connector and a buckle seat also having hooks, which respectively buckle the buckling parts of the adjacent light-emitting fans through the hooks, and the structural strength is relatively weak; on the other hand, the plate seat and buckle seat of the external connector do not have a reasonable design and a structure that is conducive to force application. In order to remove the plate seat and buckle seat, they can only be successfully disassembled and assembled using, for example, a screwdriver or other tools, which is extremely inconvenient in use and operation.
