[0005] To achieve the above objectives, the present invention proposes a computer fan with a hollow spool, comprising:

[0006] A frame, wherein the frame has a through groove in the middle, a base is provided in the middle of the through groove, and a positioning hole is provided in the middle of the base;

[0007] The cable guide tube is a tube with a cable passage. The bottom of the cable guide tube is installed in a positioning hole. The outer wall of the cable guide tube is provided with a pivot tube for pivot mounting. The upper part of the pivot tube is provided with an impeller shaft. The impeller shaft extends to a bent outer shell. The outer shell and the base form a receiving cavity. The base is provided with a PCB board. The PCB board is provided with a stator. The stator is located in the receiving cavity. The inner side wall of the outer shell is provided with a rotor that cooperates with the stator.

[0008] The upper end of the conduit extends out of the upper wall of the impeller shaft and is provided with a fixing seat. The fixing seat is equipped with an LCD display screen, which can display a predetermined pattern.

[0009] Specifically, the pivot tube is a copper tube, and a first ball bearing and a second ball bearing are provided between the pivot tube and the cable guide tube. The inner wall of the pivot tube is provided with a first positioning part and a second positioning part protruding inward. The first positioning part is in contact with the upper wall of the first ball bearing, and the second positioning part is in contact with the outer wall of the second ball bearing.

[0010] Specifically, the impeller shaft is provided with a hook part, and the copper tube is provided with a locking part that cooperates with the hook part, and the hook part and the locking part are locked together.

[0011] Specifically, a top spring is provided between the first positioning part and the second ball bearing.

[0012] Specifically, a gasket is provided between the PCB board and the base.

[0013] Specifically, the outer wall of the lower end of the conduit is provided with a limiting part, the diameter of the limiting part is larger than the diameter of the positioning hole, and the positioning hole is provided with a limiting groove that cooperates with the limiting part.

[0014] Specifically, the limiting part is provided with a groove, and the groove is provided with an elastic washer.

[0015] Specifically, the base extends upward with a surrounding portion, which is disposed opposite to the hook portion.

[0027] like Figures 1 to 4 As shown, a computer fan with a hollow spool includes:

[0028] The frame 1 has a through groove 11 in the middle, a base 12 in the middle of the through groove 11, and a through positioning hole 13 in the middle of the base 12.

[0029] The cable guide tube 2 is a tube with a cable passage 21. The bottom of the cable guide tube 2 is installed in the positioning hole 13. The outer wall of the cable guide tube 2 is provided with a pivot tube 3 for pivot mounting. The upper part of the pivot tube 3 is provided with an impeller shaft 31. The impeller shaft 31 extends to a bent outer shell 32 (where the impeller is located on the outer wall of the outer shell 32). The outer shell 32 and the base 12 form a receiving cavity 33. The base 12 is provided with a PCB board. The PCB board 4 is provided with a stator 41. The stator 41 is located in the receiving cavity 33. The inner side wall of the outer shell 32 is provided with a rotor 5 that cooperates with the stator 41.

[0030] The upper end of the conduit 2 extends out of the upper wall of the impeller shaft 31 and is provided with a fixing seat 51. The fixing seat 51 is provided with an LCD display screen 52, which can display a predetermined pattern.

[0031] In the specific installation process, the frame 1 and the base 12 are integrally molded from plastic. Then, the cable conduit 2 is installed in the positioning hole 13, the impeller shaft 31 is installed on the pivot tube 3, and the rotor 5 is fixedly installed on the inner wall of the outer shell 32. Then, the stator 41 and the PCB board 4 are integrally installed on the base 12, and the pivot tube 3 is installed on the outer wall of the cable conduit 2. Then, the fixing seat 51 is installed on the upper wall of the cable conduit 2, and the corresponding cable 22 is connected to the LCD display screen 52 through the cable channel 21, which makes the cable 22 wiring simpler. Of course, in a specific embodiment, the LCD display screen 52 can also be an LED light group, which can also achieve the same aesthetic effect. However, the LCD display screen 52 can display the corresponding logo, font or pattern, providing a more comprehensive selection. For brands or manufacturers, it can play a role in advertising. Of course, the LCD display screen 52 can also be controlled by a computer by setting a corresponding chip in the fixing seat 51. The structure of the bushing allows the LCD display screen 52 to be fixed in place, and it can also exert a certain downward pressure on the upper wall of the impeller (blade). The setting of the fixing seat 51 ensures that the impeller rotates stably at high speeds.

[0032] In this embodiment of the invention, the pivot tube 3 is a copper tube. A first ball bearing 61 and a second ball bearing 62 are spaced apart between the pivot tube 3 and the cable guide tube 2. The inner wall of the pivot tube 3 has a first positioning part 63 and a second positioning part 64 protruding inward. The first positioning part 63 is in contact with the upper wall of the first ball bearing 61, and the second positioning part 64 is in contact with the outer wall of the second ball bearing 62. This achieves stable impeller rotation and ensures high impeller speed. The ball bearings also ensure minimal friction in the pivot tube 3, while the copper tube extends its service life. Furthermore, the weight of the copper tube contributes to the stable rotation of the impeller and ensures coaxiality of the impeller rotation.

[0033] Specifically, the impeller shaft 31 is provided with a hook portion 65, and the copper tube is provided with a locking portion 66 that cooperates with the hook portion 65. The hook portion 65 and the locking portion 66 are locked together. The impeller shaft 31 can be integrally injection molded with the copper tube or it can be fixed by adhesive bonding, thereby ensuring the stable installation of the impeller shaft 31.

[0034] More specifically, a top spring 67 is provided between the first positioning part 63 and the second ball bearing 62. The top spring ensures that the impeller's upward force is buffered when it starts rotating, thus reducing friction damage. At the same time, the top spring enables the impeller to float at high speeds, avoiding eccentric rotation. The fixed seat 51 can limit the upper wall of the impeller shaft 31.

[0035] In this embodiment of the invention, a shim 40 is provided between the PCB board 4 and the base 12. The shim 40 can reduce the vibration generated when the impeller rotates.

[0036] Furthermore, the outer wall of the lower end of the conduit 2 is provided with a limiting part 71. The diameter of the limiting part 71 is larger than the diameter of the positioning hole 13. The positioning hole 13 is provided with a limiting groove 72 that cooperates with the limiting part 71, thereby facilitating the installation of the conduit 2.

[0037] Furthermore, the limiting part 71 is provided with a groove 81, and the groove 81 is provided with an elastic washer 82. The elastic washer 82 can not only facilitate the fixing of the conduit 2, but also play a shock-absorbing role.

[0038] In this embodiment of the invention, the base 12 extends upward with a surrounding portion 9, which is disposed opposite to the hook portion 65. Therefore, in actual assembly, it is not necessary to install a separate housing on the motor.

[0039] Furthermore, the inner wall of the stator 41 is fixed to the outer wall of the enclosure 9.

[0040] In this embodiment of the invention, the outer peripheral wall of the fixing base 51 is provided with a stepped portion 91, and the LCD display screen 52 is disposed on the stepped portion 91, thereby forming a cavity for mounting electronic components of the LCD display screen 52.

[0041] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
