Description

Technical Field

[0001] This invention relates to the field of computer fan technology, and more specifically, to a computer fan device with anti-backflow features. Background Technology

[0002] With the rapid upgrading of electronic products, computer hardware is becoming more and more powerful. This inevitably leads to a lot of heat being generated when these high-performance computer hardwares are in use. The higher the temperature of computer hardware during operation, the greater its performance will be. Therefore, it is necessary to set up a heat dissipation mechanism to effectively dissipate heat and ensure that the hardware maintains high performance for a long time.

[0003] Computers typically have several fans installed to dissipate heat from the electronic components inside. When the fans deliver airflow, the airflow encounters resistance and causes backflow, which in turn causes airflow turbulence and affects system heat dissipation.

[0004] Among them, the search revealed that the invention patent with patent application number CN202010474664.7 discloses a computer fan device with anti-backflow, which includes a base, a bracket fixed on the base, a drive motor mounted on the bracket, and a fan body mounted on the output shaft of the drive motor. The added control device reduces the reliability of the fan.

[0005] In use, this structure uses a reset spring to press down on the adjusting ring, which drives the unreset fan blades to swing and reset. This achieves the opening and resetting function of the corresponding fan blades after the first spring is damaged. The mechanism for disengaging the slider and the sleeve ensures that even if the first spring is damaged, the fan will not be restricted by the threaded connection between the slider and the fixed shaft when swinging under the action of wind. However, in use, this structure only serves the function of conveying airflow and cannot adjust the wind power according to the needs. This results in the structure not being targeted in conveying airflow, leading to poor heat dissipation performance. Summary of the Invention

[0006] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. To overcome the aforementioned shortcomings of existing technologies, this invention provides a computer fan device with anti-backflow features, aiming to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a computer fan device with anti-backflow function, comprising a fan device body, wherein the fan device body is provided with a wind energy regulating component for adjustment;

[0020] Several connecting sleeves for limiting position, and each of the connecting sleeves is respectively sleeved on the corresponding adjusting traction column and slidably connected to the adjusting traction column;

[0021] Several compressible energy-storing springs are provided, and each spring is respectively disposed at one end of a corresponding connecting sleeve and sleeved on the outside of the corresponding adjusting traction column.

[0022] Several second traction ball joint seats for positioning, and each of the second traction ball joint seats is distributed around the outer side of the reinforcing support ring along the circumference of the axis of the reinforcing support ring;

[0023] In this embodiment, one end of each of the second traction ball joints extends to the corresponding adjusting traction column and is movably connected to the adjusting traction column;

[0024] Each of the multiple supporting rotating rods has a first blade at one end located inside the fan device body, and a second blade is provided on one side of each first blade. Both the second blade and the first blade are detachably connected to the supporting rotating rod by bolts.

[0025] A rotatable reinforcing support ring is fitted onto the outside of the fan unit body;

[0026] Several tooth grooves, and each of the tooth grooves is distributed circumferentially along the axis of the reinforcing support ring on the upper surface of the reinforcing support ring;

[0027] Several limiting seats for support are provided, and each of the limiting seats is distributed circumferentially around the center point of the reinforcing support ring in the middle of the reinforcing support ring. The limiting seats are detachably connected to the fan equipment body by bolts.

[0028] A plurality of positioning rollers for guiding, and each of the positioning rollers is respectively disposed on a corresponding limiting seat, and the positioning rollers are movably connected to the limiting seats;

[0029] A servo motor for driving the fan is located on the outside of the fan body and is detachably connected to the fan body by bolts.

[0030] A rotatable toothed rod is disposed at the output end of a servo motor, and the toothed rod extends to and meshes with the toothed groove;

[0031] The outer side of each of the positioning rollers is in contact with the inner wall of the reinforcing support ring.

[0033] A limiting hemispherical seat is used for limiting the position, and the limiting hemispherical seat is disposed on top of the positioning center seat. The limiting hemispherical seat and the positioning center seat are detachably connected by bolts.

[0037] The technical effects and advantages of this invention are as follows:

[0038] This invention allows airflow to be gathered through the conical guide holes on the second gathering guide plate and then guided into the main body of the fan device. The airflow is then gathered again through the conical cross-section of the conical guide holes on the first gathering guide plate and ejected, making the airflow more targeted when ejected, thereby improving the heat dissipation effect of the device during use and effectively preventing the backflow phenomenon during airflow delivery.

[0039] To further improve the heat dissipation effect of the equipment, this invention uses multiple second traction ball joint seats to rotate and displace simultaneously along the axis of the reinforcing support ring. This causes the adjusting traction column to move, which in turn causes the spring-driven connecting sleeve to move. When the first traction ball joint seat is under force, it will rotate along the axis of the connection between the first traction ball joint seat and the adjusting traction column. This causes the connecting piece to drive the support rotating rod to rotate along the axis of the connection between the support rotating rod and the limiting shaft cylinder, so as to facilitate the linkage adjustment of various structures.

[0040] When the support rod rotates, the second blade and the first blade will rotate, thereby changing the angle of the first blade and the second blade. This not only adjusts the flow rate when the air is drawn, but also guides the airflow through the inclined surface after the adjustment of the first blade and the second blade, thus guiding the airflow direction. It is easy to adjust the wind power and direction according to the needs.

[0041] In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of various structures, the airflow is further concentrated and ejected through the conical cross-section of the conical guide hole on the first converging guide plate, making the airflow more targeted during ejection. This improves the heat dissipation effect of the device during use and effectively avoids backflow during air delivery. When the support rod rotates, it drives the second blade and the first blade to rotate, thereby changing the angle of the first blade and the second blade. This not only adjusts the flow rate during air extraction but also guides the airflow through the inclined surface after the adjustment of the first and second blades, thus guiding the airflow direction. It is easy to adjust the wind power and direction according to the needs. Attached Figure Description

[0065] Several reinforcing support seats 2 are provided for support, and each reinforcing support seat 2 is distributed around the circumference of the fan equipment body 1 along the axis of the fan equipment body 1 on the outside of the fan equipment body 1.

[0076] A rotatable reinforcing support ring 3 is fitted onto the outside of the main body 1 of the fan device;

[0077] Several tooth grooves 301 are provided, and each tooth groove 301 is distributed around the circumference of the axis of the reinforcing support ring 3 on the upper surface of the reinforcing support ring 3.

[0078] Several limiting seats 302 are used for support, and each limiting seat 302 is distributed around the center of the reinforcing support ring 3 in the middle of the reinforcing support ring 3. The limiting seats 302 are detachably connected to the fan equipment body 1 by bolts.

[0079] Several positioning rollers 303 are used for guidance, and each positioning roller 303 is respectively set on a corresponding limiting seat 302. The positioning rollers 303 are movably connected to the limiting seats 302.

[0080] The servo motor 304 is used for driving. The servo motor 304 is located on the outside of the fan device body 1. The servo motor 304 is detachably connected to the fan device body 1 by bolts.

[0081] A rotatable toothed rod 305 is provided at the output end of the servo motor 304. The toothed rod 305 extends to the toothed groove 301 and meshes with the toothed groove 301.

[0082] The outer side of each positioning roller 303 is in contact with the inner wall of the reinforcing support ring 3.

[0083] Positioning center seat 4 for positioning, the positioning center seat 4 is set in the middle of the fan equipment body 1;

[0084] A limiting hemispherical seat 401 is used for limiting the position. The limiting hemispherical seat 401 is disposed on top of the positioning center seat 4, and the limiting hemispherical seat 401 is detachably connected to the positioning center seat 4 by bolts.

[0085] Several positioning rod holes 402 are used for positioning, and each positioning rod hole 402 is distributed around the circumference of the positioning center seat 4 on the outer side of the positioning center seat 4.

[0086] Several support diagonal rods 403 are used for support, and each support diagonal rod 403 is distributed around the circumference of the center point of the positioning center seat 4 on the bottom outer side of the positioning center seat 4.

[0087] Among them, one end of each of the multiple support diagonal rods 403 extends to the inner wall of the fan equipment body 1, and one end of each of the multiple support rotating rods 202 extends into the corresponding positioning rod hole 402 and is engaged with the positioning rod hole 402.

[0088] According to the above structure, when in use, the staff installs the fan device made by the present invention at a designated location. During use, the device is driven by an external motor to rotate, so that the external airflow can be gathered through the conical cross-section of the conical guide hole 105 on the second gathering guide plate 104 and then guided into the main body 1 of the fan device. As the device continues to rotate, the airflow gathered by the conical cross-section of the conical guide hole 105 on the second gathering guide plate 104 will be gathered and ejected again through the conical cross-section of the conical guide hole 105 on the first gathering guide plate 103, making the airflow more targeted when ejected, thereby improving the heat dissipation effect of the device during use and effectively preventing the phenomenon of backflow of airflow during transportation.

[0089] Meanwhile, in order to further improve the heat dissipation effect of the device during use, the servo motor 304 is started to drive the toothed rod 305 to rotate. The toothed rod 305 meshes with the toothed groove 301, so that when the toothed rod 305 rotates, it drives the reinforcing support ring 3 to rotate. When the reinforcing support ring 3 rotates, it will drive multiple second traction ball joint seats 208 to rotate and displace along the axis of the reinforcing support ring 3. When the second traction ball joint seats 208 rotate and displace, they will pull the adjusting traction column 204, causing the adjusting traction column 204 to move.

[0090] When the adjusting traction column 204 is displaced, the spring 207 will be stressed, which will cause the spring 207 to drive the connecting sleeve 206 to be displaced. The first traction ball joint seat 205 is movably connected to the adjusting traction column 204, so when the first traction ball joint seat 205 is stressed, it will rotate around the axis point at the connection between the first traction ball joint seat 205 and the adjusting traction column 204, which will change the angle of the first traction ball joint seat 205. This will cause the connecting piece 202 to drive the support rotating rod 202 to rotate around the axis point at the connection between the support rotating rod 202 and the limiting shaft cylinder 201.

[0091] When the support rod 202 rotates, it will drive the second blade 210 and the first blade 209 to rotate, thereby changing the angle of the first blade 209 and the second blade 210. This not only adjusts the flow rate when the air is extracted, but also guides the airflow through the inclined surface after the adjustment of the first blade 209 and the second blade 210, thus guiding the direction of the airflow.

[0092] Furthermore, during the rotation of the reinforcing support ring 3, the positioning roller 303 rubs against the reinforcing support ring 3, guiding and limiting the rotation of the reinforcing support ring 3 to ensure the stability of the reinforcing support ring 3 during rotation.

[0093] Unlike existing technologies, this application discloses a computer fan device with anti-backflow protection. The airflow is further concentrated and ejected through the conical cross-section of the conical guide hole 105 on the first converging guide plate 103, making the airflow more targeted during ejection. This improves the heat dissipation effect of the device during use and effectively prevents backflow during air delivery. When the support rod 202 rotates, it drives the second blade 210 and the first blade 209 to rotate, thereby changing the angle of the first blade 209 and the second blade 210. This not only adjusts the flow rate during air extraction but also guides the airflow through the inclined surface of the first blade 209 and the second blade 210, directing the airflow direction. This allows for easy adjustment of the airflow intensity and direction according to requirements.

[0094] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
