[0007] For example, a positioning groove is provided on the inner wall of the movable groove, and the second positioning member includes a second positioning rod disposed in the positioning groove. A third piston is provided at one end of the second positioning rod. The diameter of the third piston is smaller than that of the first piston and the second piston. The second positioning rod passes through the inner wall of the control console. A second positioning hole is provided on the side wall of the dustproof box to cooperate with the end of the second positioning rod. A receiving groove is provided inside the control console. The second positioning rod passes through the receiving groove. A notch is provided on the inner wall of the receiving groove near the movable groove. A reset member and a reset plate are provided on the second positioning rod. The width of the reset plate is greater than the width of the notch. The reset member is sleeved on the second positioning rod. The two ends of the reset member are respectively connected to the reset plate and the inner wall of the notch near the movable groove.

[0008] For example, the reset component includes a reset spring, one end of which is connected to the inner wall of the notch near the movable groove, and the other end is connected to the reset plate.

[0009] For example, the control panel is provided with a prepositioning slot, and a prepositioning rod is movably installed in the prepositioning slot.

[0010] For example, the first drive rod is hollow, and an inner cavity is provided inside the first drive rod. The inner cavity extends through the first drive rod, and a movable rod is movably installed in the inner cavity. The movable rod slides along the inner cavity. A handle is connected to the end of the movable rod away from the dust box. The handle is mounted on the first drive rod and detachably connected to the first drive rod. The end of the movable rod away from the handle passes through the hollow cavity. A spring groove is formed at the end of the movable rod away from the handle.

[0012] For example, the inner wall of the dustproof duct is provided with multiple dustproof plates.

[0013] This application has at least the following technical effects.

[0014] 1. The fan, which serves as a heat dissipation device, is mounted on the outer casing using the structure of the first positioning component. The dustproof box, which serves as a dustproof device, is fixed to the outer casing using the second positioning component. The rotation of the fan carries heat out of the outer casing to achieve a heat dissipation effect. A dustproof net is installed on the dustproof pipe for dust prevention, and the bent dustproof pipe also has a better dust prevention effect. Finally, the dust is sent into the collection box for collection, achieving a dust prevention effect. Furthermore, the structure of the first and second positioning components makes the installation and disassembly of the heat dissipation device and the dustproof device more convenient.

[0015] 2. A structure with a first bevel gear and a second bevel gear is set in the control console. The first bevel gear is driven to rotate by the first drive rod, which in turn drives the second bevel gear and the second drive rod to rotate, thereby driving the movable block. This changes the air pressure in the movable slot, thereby driving the second piston and the third piston, causing the first positioning rod and the second positioning rod to move outward from the control console. The first positioning rod cooperates with the cooling fan, and the second positioning rod cooperates with the dust cover, finally achieving the positioning of the dust cover and the cooling fan. The installation and positioning process is relatively convenient. Attached Figure Description

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Reference Figures 1-6 This application discloses a home gateway with dustproof function, including a gateway body 1 and a shell 2 disposed outside the gateway body 1. The shell 2 is provided with a heat dissipation device and a dustproof device. The shell 2 is provided with a first mounting hole and a second mounting hole. The heat dissipation device includes a cooling fan 4 that can be detachably installed in the first mounting hole. The dustproof device includes a dustproof box 3 that can be detachably installed in the second mounting hole. A control panel 5 is provided inside the shell 2. A first positioning member for fixing the cooling fan 4 is provided inside the control panel 5. A second positioning member for fixing the dustproof box 3 is provided inside the control panel 5.

[0025] The dustproof box 3 contains a bent dustproof pipe 31. One end of the dustproof pipe 31 is located at the opening on the outside of the dustproof box 3 and is fitted with a dustproof net 32. The other end of the dustproof pipe 31 extends to the outside of the dustproof box 3 and is connected to a collection box 34. The end of the dustproof pipe 31 away from the dustproof net 32 ​​is connected to the bottom of the collection box 34. The end of the dustproof pipe 31 is provided with multiple air leakage holes 35. In addition, multiple dustproof plates 33 are provided on the inner wall of the dustproof pipe 31.

[0026] Because the dustproof box 3 is equipped with a dustproof pipe 31, air is sent into the outer casing 2 through the dustproof pipe 31. When the air enters, it blocks the dust in the air, and the dust falls into the collection box 34 for collection. Ultimately, it achieves a good dustproof effect while realizing heat dissipation. The dustproof mesh 32 at the end of the dustproof pipe 31 and the internal dustproof plate 33 also play a good role in dust prevention.

[0027] For example, the console 5 has a cavity 51, and a movable groove 52 is provided on the side of the cavity 51 near the first mounting hole. The first positioning member includes a first positioning rod 69 disposed in the movable groove 52. The console 5 is provided with a driving member that drives the first positioning rod 69 to move along the movable groove 52. The side wall of the cooling fan 4 is provided with a first positioning hole 41 that cooperates with the end of the first positioning rod 69.

[0028] Exemplarily, the driving component includes a first driving rod 6 rotatably mounted on the control console 5, a first bevel gear 61 disposed on the first driving rod 6, the axes of the first bevel gear 61 and the first driving rod 6 coinciding, a connecting plate 54 disposed within the cavity 51, a second driving rod 64 rotatably mounted on the connecting plate 54, the axes of the second driving rod 64 being perpendicular to those of the first driving rod 6, the second driving rod 64 passing through the connecting plate 54, one end of the second driving rod 64 being connected to a second bevel gear 63, the other end of the second driving rod 64 extending into a movable groove 52, the second bevel gear 63 meshing with the first bevel gear 61, and a movable part movably mounted in the second movable groove 52. Block 65, movable block 65 abuts against the inner wall of movable groove 52 and slides along movable groove 52. The second drive rod 64 is provided with external thread, and the movable block 65 is provided with threaded hole 66 that mates with the second drive rod 64. The second drive rod 64 and movable block 65 are threadedly engaged through threaded hole 66. When the second drive rod 64 rotates, it drives the movable block 65 to slide along movable groove 52. A first piston 67 is provided at the end of movable block 65 away from cavity 51, and a second piston 68 is provided at the end of first positioning rod 69 near cavity 51. Both the first piston 67 and the second piston 68 abut against the inner wall of movable groove 52 and slide along movable groove 52.

[0029] The first positioning rod 69 is used as the first positioning element. By driving the first positioning rod 69, its end extends to the outside of the control console 5 and engages with the side wall of the cooling fan 4, thus positioning the cooling fan 4. A first bevel gear 61 and a second bevel gear 63 are used. By rotating the first drive rod 6, the first bevel gear 61 rotates, driving the second bevel gear 63 and the second drive rod 64 to rotate. The second drive rod 64 is threadedly engaged with the movable block 65 in the movable groove 52. When the second drive rod 64 rotates, it drives the movable block 65 to move along the movable groove 52. The movable block 65 drives the first piston 67 to move, increasing the air pressure in the movable groove 52, causing the second piston 68 to move, thereby moving the first positioning rod 69. The end of the first positioning rod 69 engages with the side wall of the cooling fan 4, thus positioning the cooling fan 4.

[0030] For example, a positioning groove 7 is provided on the inner wall of the movable groove 52. The second positioning component includes a second positioning rod 72 disposed in the positioning groove 7. A third piston 71 is provided at one end of the second positioning rod 72. The diameter of the third piston 71 is smaller than that of the first piston 67 and the second piston 68. The second positioning rod 72 passes through the inner wall of the control console 5. A second positioning hole 36 is provided on the side wall of the dustproof box 3 to mate with the end of the second positioning rod 72. A receiving groove 53 is provided inside the control console 5. The second positioning rod 72 passes through the receiving groove 53. A notch 75 is provided on the inner wall of the receiving groove 53 near the movable groove 52. A reset component and a reset plate 73 are provided on the second positioning rod 72. The width of the reset plate 73 is greater than the width of the notch 75. The reset component is sleeved on the second positioning rod 72. The two ends of the reset component are respectively connected to the reset plate 73 and the inner wall of the notch 75 near the movable groove 52. The reset component includes a reset spring 74. One end of the reset spring 74 is connected to the inner wall of the notch 75 near the movable groove 52, and the other end is connected to the reset plate 73.

[0031] The second positioning rod 72 serves as the second positioning element. When the second positioning rod 72 is driven to move, its end engages with the second positioning hole 36 on the side wall of the dust box 3, thus positioning the dust box 3. The third piston 71 and positioning groove 7 are also used. As the air pressure in the movable groove 52 gradually increases, the third piston 71 moves under the pressure, thereby moving the second positioning rod 72. The second positioning rod 72 extends to the outside of the control console 5 and engages with the side wall of the dust box 3, thus positioning the dust box 3. It should be noted that because the third piston 71 is smaller than the second piston 68 and the first piston 67, and the second positioning rod 72 connected to the third piston 71 is also subject to the pressure of the return spring 74, a greater air pressure is required to drive the third piston 71 to move in the positioning groove 7 compared to the second piston 68. When driving the second piston 68 and the third piston 71, the first piston 67 moves and increases the air pressure. Under the action of the air pressure, the second piston 68 drives the first positioning rod 69 to move, thereby positioning the cooling fan 4. When the first positioning rod 69 can no longer move, the air pressure in the movable groove 52 will continue to increase. Only then will the third piston 71 overcome the friction and the elasticity of the return spring 74 to move, ultimately driving the second positioning rod 72 to move and cooperate with the dust box 3. Therefore, during positioning, the cooling fan 4 is positioned first, followed by the dust box 3. When the first drive rod 6 and the first bevel gear 61 rotate in opposite directions to disassemble the cooling fan 4 and the dust box 3, the dust box 3 will be disassembled first, followed by the cooling fan 4. The reason for adopting the above solution is that the dust box 3 is installed and removed more frequently than the cooling fan 4. After the cooling fan 4 is positioned, only the dust box 3 needs to be installed and removed for a long time.

[0032] For example, the control panel 5 is provided with a pre-positioning slot 55, and a pre-positioning rod 57 is movably installed in the pre-positioning slot 55. One end of the pre-positioning rod 57 is hemispherical and extends to the outside of the pre-positioning slot 55. A pre-positioning hole is provided on the side wall of the cooling fan 4 to cooperate with the end of the pre-positioning rod 57. A first positioning spring 56 is provided in the pre-positioning slot 55, and the two ends of the first positioning spring 56 are respectively connected to the inner wall of the end of the pre-positioning rod 57 and the pre-positioning slot 55. Through the structure of the pre-positioning component, the cooling fan 4 can be initially positioned, which facilitates the subsequent installation and positioning of the cooling fan 4.

[0033] For example, the first drive rod 6 is hollow, and an inner cavity is provided inside the first drive rod 6. The inner cavity extends through the first drive rod 6, and a movable rod 8 is movably installed in the inner cavity. The movable rod 8 slides along the inner cavity. A handle 62 is connected to the end of the movable rod 8 away from the dustproof box 3. The handle 62 is sleeved on the first drive rod 6 and detachably connected to the first drive rod 6. The end of the movable rod 8 away from the handle 62 passes through the cavity 51. A spring groove is opened at the end of the movable rod 8 away from the handle 62. A spring block 81 is movably installed in the spring groove. The end of the spring block 81 is set as a hemispherical shape and extends to the outside of the control console 5. A locking hole is provided on the dustproof box 3 to cooperate with the end of the spring block 81. A second positioning spring 82 is connected in the spring groove. The two ends of the second positioning spring 82 are respectively connected to the inner wall of the end of the spring block 81 and the spring groove. With the above structure, the first drive rod 6 is hollow, and a movable rod 8 is set inside the hollow first drive rod 6. A spring block 81 and a second positioning spring 82 are set at the end of the movable rod 8 to perform initial positioning of the dust box 3, which facilitates subsequent installation and further positioning.

[0034] For example, the side wall of the console 5 is provided with a groove to accommodate a handle 62. A sleeve 9 is provided on the handle 62, and the handle 62 is sleeved on the outside of the first drive rod 6 through the sleeve 9. A locking block is provided at the end of the first drive rod 6, and a slot 91 that cooperates with the locking block is provided on the inner side of the sleeve 9. A magnet is provided on the inner wall of the end of the sleeve 9 and is connected to the first drive rod 6 through the magnet. The connection between the handle 62 and the first drive rod 6 is achieved by the structure of the sleeve 9 sleeved on the first drive rod 6 and the structure of the magnet for positioning. The locking block on the first drive rod 6 cooperates with the slot 91 on the sleeve 9, so that the first drive rod 6 can be rotated when the handle 62 is rotated.

[0035] The operating principle of this embodiment is as follows: First, the cooling fan 4 is inserted into the outer casing 2, and pre-positioning is achieved through the cooperation of the pre-positioning rod 57 and the cooling fan 4. Then, the dust box 3 is initially positioned by the spring block 81 at the end of the movable rod 8.

[0036] Next, rotating the first drive rod 6 causes the first bevel gear 61 to rotate, which in turn drives the second bevel gear 63 and the second drive rod 64 to rotate. The second drive rod 64 is threadedly engaged with the movable block 65 in the movable groove 52. When the second drive rod 64 rotates, it drives the movable block 65 to move along the movable groove 52. The movable block 65 drives the first piston 67 to move, increasing the air pressure in the movable groove 52, causing the second piston 68 to move. This causes the first positioning rod 69 to move, and the end of the first positioning rod 69 engages with the side wall of the cooling fan 4, thus positioning the cooling fan 4. When the first positioning rod 69 can no longer move, the air pressure in the movable groove 52 will continue to rise. Then, the third piston 71 will overcome the friction and the elastic force of the return spring 74 to move, ultimately driving the second positioning rod 72 to move and engage with the dust cover 3. Therefore, during positioning, the cooling fan 4 is positioned first, and then the dust cover 3 is positioned. This completes the positioning and installation of the cooling fan 4 and the dust cover 3. Similarly, the cooling fan 4 and the dust box 3 can be disassembled by rotating the first drive rod 6 and the first bevel gear 61 in opposite directions.

[0037] A home gateway with dustproof function according to an embodiment of this application has good dustproof effect while dissipating heat. Furthermore, the cooling fan 4 and dustproof box 3 are easy to install and remove, facilitating disassembly and replacement.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
