Description

Technical Field

[0001] The utility model relates to the field of computer hardware, in particular to a heat dissipation fan for a computer host. Background Art

[0002] Computer hosts generate a lot of heat due to the hardware, so a cooling fan needs to be installed on the side of the body to cool the inside. However, traditional host cooling fans carry static electricity due to the high-speed friction between the fan blades and the air during use, which in turn absorbs a large amount of dust, resulting in a decrease in speed and unstable rotation, which ultimately greatly reduces the cooling effect. The dust needs to be cleaned regularly to maintain the best cooling effect, which is inconvenient to use. Utility Model Content

[0017] Example 1

[0018] Please refer to Figure 1-Figure 2 , Figure 1-Figure 2 An embodiment of the present application is shown.

[0019] The present embodiment provides a computer host cooling fan, comprising a frame 1 and a fan body 2, a motor 5 is connected between the fan body 2 and the frame 1, and antistatic films 4 are attached to the front and back sides of the fan body 2.

[0020] When using, Figure 2 As shown, antistatic films 4 are attached to both sides of the fan body 2 .

[0021] It should be noted that the antistatic film 4 is an antistatic film with a PET substrate, which can be purchased by those skilled in the art through various channels, and no specific description or limitation is given here.

[0022] Through the above technical solution, the antistatic film 4 of PET material is attached to the front and back large surfaces of the fan body 2 to prevent the fan body 2 from rubbing against the air to generate static electricity and then absorb dust, thereby reducing the cleaning work of the cooling fan and improving the convenience of use.

[0023] As a preferred embodiment, a mounting groove 201 is opened in the middle of the fan body 2, a control board 302 is clamped in the mounting groove 201, a single-chip computer 305 and a vibration motor 303 are welded on the control board 302, a cover plate 301 is arranged on the outside of the vibration motor 303, the cover plate 301 is threadedly connected to the mounting groove 201 and presses the control board 302 to position it.

[0024] When in use, the core wire of the motor 5 is connected in parallel with a wire to the main shaft of the motor 5. The fan body 2 is used to be plugged into the socket of the main shaft and is pre-buried with a metal wire. The metal wire passes through the fan body 2 and is welded to the control board 302, and stores energy through electronic components such as capacitors. After the motor 5 is powered off, the capacitor discharges and drives the coin-shaped rotor type vibration motor 303 to perform short-term high-frequency vibration on the fan body 2 to shake off the residual attachments on it.

[0025] It should be noted that after the electrical components are welded on the control board 302, it is necessary to perform a dynamic balance test on the fan body 2 and insert metal wires to adjust the weight of the fan body 2.

[0026] Through the above technical solution, a coin-shaped rotor vibration motor 303 and a single-chip microcomputer 305 are installed in the middle of the fan body 2. The fan body 2 is vibrated by the main shaft of the motor 5 and the wire to further clean the attached dust, thereby improving the self-cleaning performance of the cooling fan.

[0029] When in use, when the fan body 2 stops rotating, the gyroscope 304 loses the changing vector signal, and the single-chip computer 305 loses the vector signal and sends a pulse command to drive the vibration motor 303 to perform short-term high-frequency vibration, thereby cleaning a small amount of dust on the surface of the antistatic film 4.

[0030] Through the above technical solution, the battery 306 is used to power the single chip microcomputer 305, which simplifies the power supply method of the vibration motor 303 and reduces the manufacturing cost and difficulty.

[0031] In summary, the embodiments of the present invention provide a computer host cooling fan, which has at least the following advantages over the prior art:

[0032] 1. The anti-static film 4 made of PET material is attached to the front and back surfaces of the fan body 2 to prevent the fan body 2 from rubbing against the air to generate static electricity and then absorb dust, thereby reducing the dust cleaning work of the cooling fan and improving the convenience of use;

[0033] 2. A coin-shaped rotor vibration motor 303 and a single-chip microcomputer 305 are installed in the middle of the fan body 2.
