Description

Technical Field

[0001] This utility model belongs to the field of electronic device technology, and in particular relates to a circular side mirror fan. Background Technology

[0002] Case fans are a key component of a computer hardware cooling system. They lower the internal temperature of the case by forcing airflow, ensuring the stable operation of core components such as the CPU and graphics card. Common sizes include 80mm, 120mm, and 140mm. Fan speed (800-2000RPM) and airflow (20-100CFM) determine cooling efficiency. Quietly designed fans utilize optimized fluid dynamics to reduce noise. During installation, pay attention to the airflow direction (front-to-back or bottom-to-top). Using a dust filter can extend the lifespan of the fan. Some high-end fans support RGB lighting and PWM speed control, balancing performance and personalization needs, making them essential accessories for DIY PC builds and case upgrades.

[0003] Most current computer case fans are fixed with screws during installation. However, fans vibrate during long-term operation, and if the screws loosen, the vibration will increase and noise will be generated. In addition, the lighting effects of computer case fans only change colors and do not have reflective effects, making the effect relatively simple. To address these issues, we offer a round side mirror fan. Utility Model Content

[0004] The purpose of this invention is to provide a circular side mirror fan, which solves the problems of loose screws and limited lighting effects in existing chassis fans after installation by using a combination of reflective and mounting components.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model is a circular side mirror fan, including a lower shell, an upper shell mounted on the top of the lower shell, and a drive fan installed inside the lower shell; a reflective assembly is installed inside the lower shell, the reflective assembly including a light guide ring installed inside the lower shell and a lens body installed on one side of the drive fan; a mounting assembly is provided on one side of the lower shell, the mounting assembly including mounting holes opened inside the lower shell and the upper shell, a screw rod passing through the mounting holes, a snap-fit ​​groove opened on the surface of the screw rod, and a snap-fit ​​spring set inside the snap-fit ​​groove.

[0007] The present invention is further configured such that the mounting assembly includes a nut threaded to the top of the screw and a top ring mounted on the bottom of the nut.

[0008] The present invention is further configured such that a first damping ring is fitted on the surface of the screw and at the bottom of the lower shell, and a second damping ring is fitted on the surface of the screw and at the top of the upper shell.

[0009] The present invention is further configured such that the nut has an internal thread, and the bottom of the top ring is in contact with the first damping ring.

[0010] The present invention is further configured such that the lens body is a coated lens, and the coated lens includes a glass body and a coating layer.

[0011] The present invention is further configured such that the light guide ring includes an outer mirror and an inner mirror, and has a built-in LED light module, wherein the LED light module diffuses the light source through the light guide.

[0012] The present invention has the following beneficial effects.

[0013] 1. This utility model uses a first and a second damping ring fitted on the surface of the screw, located at the top of the upper shell and the bottom of the lower shell respectively. This effectively absorbs the vibration generated when driving the fan, reducing noise. The snap ring in the snap groove prevents the first damping ring from moving upward, avoiding the fan from shaking due to the nut loosening due to vibration. In addition, the top ring at the bottom of the nut contacts the first damping ring, further dispersing the pressure and preventing the bolt from loosening due to long-term vibration. This structural design allows the fan to remain stable even when running at high speed, avoiding installation failure or increased noise caused by vibration.

[0014] 2. This utility model achieves richer lighting visual effects through the design of the reflective component. The light guide ring has a built-in LED light module, and the light source is diffused through the outer and inner mirror structures to form a dynamic light effect like a thousand-layer mirror. The mirror body is made of coated glass, and the coating layer on its surface can enhance light refraction, so that four light strips are displayed on the front of the fan, and a ring light effect is formed on the side. The overall presentation presents a visually advanced experience. This design not only improves the aesthetics of the fan, but also provides users with personalized lighting customization options, making it adaptable to the modification needs of different styles of computer cases, and solving the problem of the monotonous lighting effects of traditional computer case fans.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-6 This utility model is a circular side-mirror fan, including a lower shell 1, an upper shell 2 mounted on the top of the lower shell 1, and a drive fan 3 installed inside the lower shell 1. The drive fan 3 is installed inside the upper shell 2 and the lower shell 1. When the motor inside the drive fan 3 is powered on, it drives the fan blades to rotate at high speed. The fan blades push the air, causing the air to flow from one side of the fan to the other side, thus achieving the function of ventilation. A reflective component 4 is installed inside the lower shell 1. The reflective component 4 includes a light guide ring 401 installed inside the lower shell 1 and a mirror mounted on one side of the drive fan 3. The sheet body 402; a mounting component 5 is provided on one side of the lower shell 1. The mounting component 5 includes a mounting hole 501 opened inside the lower shell 1 and the upper shell 2, a screw 502 that passes through the mounting hole 501, a snap-fit ​​groove 503 opened on the surface of the screw 502, and a snap-fit ​​spring 504 that can be installed inside the snap-fit ​​groove 503 to prevent the first damping ring 6 from moving upward and reduce the lifting effect on the nut 505.

[0027] Example 2

[0028] Please see Figures 1-6Based on embodiment 1, the mounting assembly 5 further includes a nut 505 threaded to the top of the screw 502, a top ring 506 mounted on the bottom of the nut 505, a first damping ring 6 fitted on the surface of the screw 502 and located at the bottom of the lower shell 1, and a second damping ring 7 fitted on the surface of the screw 502 and located at the top of the upper shell 2. The first and second damping rings 6 are made of rubber and are respectively placed on one side of the upper shell 2 and the lower shell 1 to dampen vibrations during the operation of the drive fan 3. The nut 505 has an internal thread, and the bottom of the top ring 506 contacts the first damping ring 6. The lens body 402 is a coated lens, which includes a glass body and a coating layer. The light guide ring 401 includes an outer lens and an inner lens, and has a built-in LED light module. The LED light module is guided by the light guide ring. The light source is diffused by the light guide ring 401, which is equipped with an outer and inner mirror. The LED light module diffuses the light source through the light guide ring 401 to achieve the effect of a multi-layered mirror. The lens body 402 is a coated lens, which includes a glass body and a coating layer. The coating layer is located on the front surface of the glass body to enhance the light refraction effect and form a visual effect of a multi-layered mirror around the fan. The front end extends upward from the four corners of the light guide ring 401 and combines with the outer shell to present light strips around the four sides of the fan, making the fan more attractive and improving the overall aesthetics. Users can choose different light colors, modes and effects according to their preferences and needs, thus customizing the case to a unique appearance to showcase personal taste and style.

[0029] The working principle of this utility model is as follows: When installing the fan housing, the operator inserts the screw 502 through the fixing hole of the chassis plate, then puts the second damping ring 7 onto the surface of the screw 502, and passes it through the mounting holes 501 inside the upper shell 2 and lower shell 1 in sequence. Then, the second damping ring 7 is put on, and the nut 505 is rotated to connect with the screw 502. When the nut 505 rotates on the surface of the screw 502, it pushes the top ring 506 to move. The top ring 506 pushes the first damping ring 6 to move downward, pressing the fan housing and exposing the snap-fit ​​groove 503. Then, the snap ring 504 is put into the snap-fit ​​groove 503 to prevent the first damping ring 6 from moving upward, reducing the lifting effect on the nut 505, and preventing the fan housing from shaking when the nut 505 becomes loose, thus improving the stability of the installation.

[0030] The light guide ring 401 is equipped with an outer mirror and an inner mirror. The LED light module diffuses the light source through the light guide ring 401 to achieve the corresponding effect of the multi-layered mirror. The lens body 402 is a coated lens, which includes a glass body and a coating layer. The coating layer is located on the front surface of the glass body to enhance the light refraction effect and form a visual effect of a ring-shaped multi-layered mirror around the fan. The front end extends upward from the four corners of the light guide ring 401 and combines with the outer shell to present light-emitting strips around the four sides of the fan, making the fan more attractive and improving the overall aesthetics.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
