Description

Technical Field

[0001] The present invention relates to a fan device, and more particularly to a fan having a series connection structure. Background Art

[0002] In the prior art, heat dissipation components installed inside a computer mainframe or a server have various types of structures, and one of them is a fan. Due to the requirements of use, as the computing speed of devices such as computers or servers continues to increase, the generated heat energy also increases. Therefore, effective heat dissipation must be carried out to maintain the normal operation of the computer device. In order to improve the heat dissipation efficiency, one way is to install two or more fans inside the computer device to quickly discharge the hot air generated inside, so that cold air can flow in to maintain the device at a working temperature and operate normally.

[0003] When adding fans inside the device, in addition to installing and fixing each fan one by one, multiple wires for supplying power must be added. When the number of added fans increases, the number of wires for connecting power must also be increased. Such multiple wires will cause clutter inside the device and cause trouble and inconvenience in wire configuration and maintenance. Summary of the Invention

[0004] In view of the problems and disadvantages of the fans used in the foregoing prior art, the present invention re-creates a series connection combination of multiple fans to achieve the practical purposes of simple operation and less clutter inside the device.

[0005] In order to achieve the foregoing creative purpose, the technical means used in the present invention is to provide a fan having a series connection structure, which includes a casing, a fan blade, a wire, and a magnetic attraction group; the casing is a hollow shell, and both sides of its upper part respectively have a first guide seat and a first bearing seat. The first guide seat is formed with an upper sliding hole through it. Both sides of the lower part of the casing respectively have a second guide seat and a second bearing seat. The second guide seat is formed with a lower sliding hole through it; the fan blade is assembled inside the casing; both ends of the wire are a terminal and a terminal interface respectively. The wire is electrically connected to the fan blade. A first slider is provided outside the terminal. The first slider can move in the upper sliding hole and protrude outside the casing. The terminal interface is assembled on the first bearing seat; the magnetic attraction group includes a first magnetic attraction member and a second magnetic attraction member. When the first magnetic attraction member and the second magnetic attraction member are in contact, they can adsorb and fix each other. A second slider is provided outside the first magnetic attraction member. The second slider can move in the lower sliding hole and protrude outside the casing. The second magnetic attraction member is assembled on the second bearing seat.

[0053] One end of the wire 30 is connected to a terminal 31. There is a first slider 311 outside the terminal 31. A handle 312 protrudes from the wall surface of the first slider 311. The outer shape of the first slider 311 matches the shape of the upper sliding hole 111, so that the first slider 311 can move in the upper sliding hole 111. The handle 312 of the first slider 311 passes through and is extended to the outside of the housing 10, as Figure 7 shown. Additionally, by moving the handle 312 in the upper guide groove 112, the distance and position of the first slider 311 protruding from the housing 10 are controlled. The other end of the wire 30 is connected to a terminal interface 32. The terminal interface 32 is assembled in the upper groove 121 of the first seat 12. The wire 30 passes through a through hole at the bottom of the upper groove 121. The outer diameter of the first slider 311 is smaller than the diameter of the upper groove 121. Additionally, the wire 30 is electrically connected to the driving device of the fan blade 20.

[0054] The magnetic attraction group 40 includes a first magnetic attraction member 41 and a second magnetic attraction member 42. The first magnetic attraction member 41 and the second magnetic attraction member 42 have the function of attracting each other when they are in contact. In a specific embodiment of the present invention, both the first magnetic attraction member 41 and the second magnetic attraction member 42 can be magnets, or one can be a magnet and the other can be a metal piece made of iron. The first magnetic attraction member 41 has a second slider 43 outside. A handle 431 protrudes from the wall surface of the second slider 43.
