this paper relates to a computer host switch, in particular to a computer host switch with the functions of indicating lamp reflecting the temperature inside the host chassis and adjusting the rotation speed of the computer cooling fan .

in the existing computer, the central processing unit and other electronic equipment inside the mainframe box will release a large amount of heat.in order to ensure the normal and stable operation of the computer system, these heat must be quickly and timely distributed. Therefore, in the computer host chassis heat dissipation fans should be installed inside to help dissipate heat. The amount of heat generated by computer electronic components fluctuates somewhat. At present, there is no indicator lamp on the chassis panel that can reflect the internal temperature of the host chassis, and there is no indicator lamp that can adjust the cooling air of the computer fan speed device, can't do according to the actual change to adjust the speed of the cooling fan.

the purpose of this paper is to provide a kind of computer host switch with the function of indicating lamp reflecting the temperature inside the host chassis and adjusting the rotating speed of the computer cooling fan.

in order to achieve the above objectives, this paper provides a computer host switch with a temperature indicator lamp and a radiator fan governor, which comprises a box body, a transparent lamp plug, a radiator fan rotation speed adjusting knob, a power switch button and two chassis temperature indicator lamps:the lamp plug is installed in the through hole of the cooling fan rotation speed adjustment button; The temperature indicator lamps of the two chassis are inserted into the two accommodating holes of the lamp insertion piece.

this article has the following beneficial effects:in this article, two cabinet temperature indicator lamps are installed beside the power switch button.when the internal temperature of the cabinet reaches a predetermined temperature value, the two indicator lamps will emit light.since the lamp plug-in is transparent, people can read the information from the cabinet panel place to see the effect of the two lights, you can know the internal temperature of the chassis has been relatively high; A cooling fan rotation speed adjusting knob is installed beside the power switch button 4.when people see that two chassis temperature indicator lights are emitting light, they can adjust the cooling fan rotation speed adjust the knob to speed up the rotation speed of the heat dissipation fan, so that the heat in the chassis dissipates quickly, ensuring the safe and stable work of the computer system.

the box 1 includes a circuit board (not shown) with a power switch control circuit and a cooling fan rotation speed adjustment control circuit, an electrical connector (not shown) connected to the circuit board, and a plurality of wires 6 connected to the electrical connector, which transmit electrical signals to electricity brain host chassis on the corresponding hardware devices.

the lamp insert 2 is inserted on one side of the box body 1, with an annular shell 22 in the middle, a circular opening 24 in the middle, and a receiving hole 26 extending outward from the opposite ends of the shell 22. The whole of the lamp insert 2 is made of transparent material

the cooling fan rotation speed adjusting knob 3 is a cylindrical shell, which is installed in the opening 24 of the lamp insert 2.a circular through hole 32 is formed in the middle of the shell.the cooling fan rotation speed adjusting knob 3 can rotate in the opposite direction, and when rotating in a certain direction control the cooling fan speed up, when rotating in the opposite direction control cooling fan speed slow down.

the power switch button 4 is installed in the through hole 32 of the heat dissipation fan rotation speed adjustment button 3, the main body of the power switch button 4 is turned on once, and the main body of the power switch button 4 is turned off again.

the two chassis temperature indicator lamps 5 are connected to a lead 7, the other end of which is connected to a temperature sensor in the computer chassis, and the two chassis temperature indicator lamps 5 are respectively inserted into receiving holes 26 at both ends of the lamp plug-in piece 2. When the internal temperature of the chassis reaches a predetermined temperature value time, the two indicator lights 5 illuminate.

in this article, two cabinet temperature indicator lights 5 are installed beside the power switch button 4.when the internal temperature of the cabinet reaches a predetermined temperature value, the two indicator lights 5 will illuminate.since the lamp plug 2 is transparent, people can see the two indicator lights 5 from the cabinet panel the effect of light, you can know the internal temperature of the chassis has been relatively high; A cooling fan speed adjustment knob 3 is installed beside the power switch button 4.when a person sees two chassis temperature indicator lights 5 emitting light, the cooling fan speed adjustment knob 3 can be adjusted to speed up the rotating speed of the cooling fan enables the heat in the chassis to dissipate quickly, ensuring the safe and stable operation of the computer system.
