Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, specifically relating to a cooling fan with waterproof effect. Background Technology

[0002] Cooling fans have reached a mature stage in terms of technology and performance, and new technologies are constantly emerging. The working principle of cooling fans is based on energy conversion, namely: electrical energy → electromagnetic energy → mechanical energy → kinetic energy.

[0003] A search revealed that CN215256902U discloses a booster cooling fan for a photovoltaic inverter, comprising an outer casing, an inner casing mounted between the inner walls of the outer casing via a buffer mechanism, a motor mounted between the inner walls of the inner casing via a first mounting bracket, a first fan blade fixedly mounted on the output shaft of the motor, a shroud mounted on the lower surface of the inner casing via a first fixing mechanism, a filter screen disposed between the inner walls of the shroud near the lower side, cooling fins evenly embedded circumferentially on the inner wall of the shroud above the filter screen, and a waterproof and breathable membrane fixedly mounted between the inner walls of the shroud above the cooling fins. This invention enhances the dustproof and waterproof performance of the cooling fan, preventing dust and moisture from entering, improving the service life of the cooling fan and inverter, while also providing better heat dissipation, increasing the fan pressure, resulting in faster airflow, improved heat dissipation efficiency, and ease of use.

[0004] The above solution can increase the dustproof and waterproof effect of the cooling fan, prevent dust and moisture from entering, and extend the service life of the cooling fan and inverter. However, after long-term use, the filter will accumulate a lot of dust, affecting the ventilation effect, and the waterproof breathable membrane may also be damaged. Furthermore, the above solution is not convenient for disassembling and assembling the filter and the waterproof breathable membrane, making it inconvenient to clean the filter and replace the waterproof breathable membrane. Therefore, it is necessary to design a cooling fan with waterproof effect to solve the above defects, which is of great importance. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cooling fan with waterproof effect. The main body of the cooling fan solves the problem that under the prior art, after a long period of use, the filter screen will be covered with a lot of dust, which will affect the ventilation effect and the waterproof breathable membrane may also be damaged. Furthermore, the above solutions are not convenient for disassembling and assembling the filter screen and the waterproof breathable membrane, thus making it inconvenient to clean the filter screen and replace the waterproof breathable membrane.

[0007] (2) Technical solution

[0008] To solve the above-mentioned technical problems, this utility model provides a waterproof cooling fan, which includes a cooling fan body; a connecting shell is fixedly connected to the rear end of the cooling fan body, and two sets of connecting frames are provided inside the connecting shell. The two sets of connecting frames are respectively provided with a dustproof mesh and a waterproof and breathable membrane. A connecting component is provided at the top of the connecting frame, and a fixing frame is provided at the front end of the cooling fan body. A closing component is provided inside the fixing frame.

[0009] The connecting assembly is used to install the connecting frame inside the connecting shell.

This, in turn, causes multiple sets of driven gears to rotate, which in turn drives multiple sets of closing plates to rotate. These closing plates close the fixed frame and the front end of the cooling fan body, preventing moisture and dust from entering the cooling fan body and affecting its operation. When the closing plate rotates to a specified angle, the pull rod is released, and the compression spring causes the moving ring to move, causing the limit rod to move into the limit groove and connect with the fixed frame to limit the closing plate.

[0012] Preferably, a positioning groove is provided on the top of the connecting shell and on the outside of the positioning block. The internal structure size of the positioning groove is designed to correspond to the external structure size of the positioning block. The connecting plate is connected to the positioning groove through the positioning block.

[0013] Furthermore, the fixed block has a fixed groove inside, and the size of the internal structure of the fixed groove is designed to correspond to the size of the external structure of the rotating rod. The fixed block is connected to the rotating rod through the fixed groove.

[0014] Furthermore, the closing assembly consists of multiple sets of closing plates, multiple sets of driven gears, a driving gear, and a drive rod. The multiple sets of closing plates are rotatably connected to the inside of the fixed frame, the driven gears are fixedly connected to the top of the closing plates, the driving gears are rotatably connected to the top of the inside of the fixed frame, and the drive rods are fixedly connected to the inside of the driving gears.

[0015] Furthermore, the driven gear and the fixed frame are rotatably connected, and multiple sets of driven gears are meshed with each other.

[0016] Furthermore, the driving gear meshes with the driven gear, the drive rod is rotatably connected to the fixed frame, and both ends of the top of the drive rod are slidably connected to limit rods. The fixed frame is connected to the limit rods through multiple sets of limit grooves.

[0017] Furthermore, a movable ring is fixedly connected to the outside of the limiting rod and inside the drive rod, and a compression spring is provided on the top of the movable ring and outside the limiting rod. The two sets of limiting rods are connected by a pull rod.

[0030] The connecting assembly 6 is used to install the connecting frame 3 inside the connecting shell 2. The connecting assembly 6 consists of a connecting plate 9, a rotating rod 10, two sets of fixing blocks 11 and two sets of positioning blocks 12.

[0031] The closing component 8 is used to close the front end of the cooling fan body 1.

[0032] In this embodiment, a positioning groove is provided on the top of the connecting shell 2 and on the outside of the positioning block 12. The internal structure size of the positioning groove is designed to correspond to the external structure size of the positioning block 12. The connecting plate 9 is connected to the positioning groove through the positioning block 12.

The internal structure size of the fixing groove is designed to correspond to the external structure size of the rotating rod 10. The fixing block 11 is connected to the rotating rod 10 through the fixing groove. When the rotating rod 10 is rotated, it is rotated to the inside of the fixing groove and connected to the fixing block 11 for a limiting connection, so that the connecting frame 3 can be installed inside the connecting shell 2.

[0034] Furthermore, in this embodiment, the closing assembly 8 consists of multiple sets of closing plates 13, multiple sets of driven gears 14, a driving gear 15, and a drive rod 16. The multiple sets of closing plates 13 are rotatably connected to the inside of the fixed frame 7. The driven gears 14 are fixedly connected to the top of the closing plates 13. The driving gears 15 are rotatably connected to the top of the inside of the fixed frame 7. The drive rod 16 is fixedly connected to the inside of the driving gears 15. When the cooling fan body 1 is not in use, the closing assembly 8 can close the front end of the cooling fan body 1 to prevent moisture and dust from entering the inside of the cooling fan body 1 and affecting the use of the cooling fan body 1.

[0035] Furthermore, in this embodiment, the driven gear 14 is rotatably connected to the fixed frame 7, and multiple sets of driven gears 14 are meshed with each other. The driving gear 15 is meshed with the driven gear 14, and the drive rod 16 is rotatably connected to the fixed frame 7. Rotating the drive rod 16 drives the driving gear 15 to rotate, causing the meshed driven gear 14 to rotate, thereby causing multiple sets of driven gears 14 to rotate, driving multiple sets of closing plates 13 to rotate, and the multiple sets of closing plates 13 can close the fixed frame 7.

[0036] Furthermore, in this embodiment, both ends of the top of the drive rod 16 are slidably connected to limit rods 17.

The rotating rod 10 is rotated to the inside of the fixing groove and is limited to the fixing block 11, so that the connecting frame 3 can be installed inside the connecting shell 2. When disassembling and assembling the dustproof net 4 and the waterproof breathable membrane 5, it is convenient to disassemble and assemble the dustproof net 4 and the waterproof breathable membrane 5, thereby facilitating the cleaning of the dustproof net 4 and the replacement of the waterproof breathable membrane 5. When the cooling fan body 1 is not in use, the pull rod 19 is pulled to displace the limiting rod 17, thereby displacing the inside of the limiting groove, so that the drive rod 16 can rotate. Rotating the drive rod 16 leads to The driving gear 15 rotates, causing the driven gear 14 it meshes with to rotate, which in turn causes multiple sets of driven gears 14 to rotate, driving multiple sets of closing plates 13 to rotate. The multiple sets of closing plates 13 can close the fixed frame 7 and the front end of the cooling fan body 1, preventing moisture and dust from entering the interior of the cooling fan body 1 and affecting its use. When the closing plate 13 rotates to a specified angle, the pull rod 19 is released, and the moving ring is displaced by the compression spring 18, causing the limiting rod 17 to move into the limiting groove and connect with the fixed frame 7 to limit the closing plate 13. Compared with existing cooling fans, this utility model improves the overall practicality of the cooling fan through its design.
