[0033] Reference Figs. 1 to 4 :

[0034] The present application first provides an embodiment of a fan hub vent structure, which includes:

[0035] The hub body 01, the hole plate 02, the filter cotton 03 and the fixed plate 04, the hub body 01 is provided with a vent 05, the hole plate 02 is provided with a vent hole 06, the hole plate 02 covers the vent 05, the filter cotton 03 is fixed on the vent 05 through the fixed plate 04, so that the filter cotton 03 covers the hole plate 02.

[0036] This embodiment is a fan hub vent 05 structure, which includes the following main components:

[0037] Hub body 01: Hub body 01 is the basis of the entire vent 05 structure, which is part of the fan hub, and is provided with a vent 05. Hub body 01 is usually made of durable materials such as metal or plastic to ensure its strength and stability under different environmental conditions.

[0038] Hole plate 02: Hole plate 02 is a component that covers the vent 05 of hub body 01 and has multiple vent holes 06. The arrangement and size of these vent holes 06 may be carefully designed according to ventilation requirements and system design. Hole plate 02 can be made of metal or plastic to ensure its strength and light weight.

[0039] Filter cotton 03: Filter cotton 03 is fixed on the vent 05 of hub body 01 through fixed plate 04, which is used to filter dust and impurities in the air entering the system. Filter cotton 03 usually uses high-efficiency filtering materials such as fiberglass or synthetic fibers to ensure good filtering effect.

[0040] Fixed plate 04: Fixed plate 04 is a component that firmly fixes filter cotton 03 on vent 05. Fixed plate 04 may be made of durable materials such as metal or plastic, and its design should consider stability, durability and the characteristics of easy replacement of filter cotton 03. Fixed plate 04 is connected with hub body 01 to ensure the firmness and safety of the entire structure.

[0041] The operating principle of this fan hub vent 05 structure is that external air is introduced into the system through the vent 05 on the hub body 01. Vent holes 06 are arranged on hole plate 02, and filter cotton 03 is fixed on hole plate 02. In this way, the air entering the system is filtered, and dust and impurities are blocked by filter cotton 03, and clean air enters the interior of the system.

[0042] This is a key design feature that can further improve the performance and reliability of the entire fan hub vent 05 structure. The following is a detailed description of this feature:

[0043] The hole plate 02 is designed to completely cover the ventilation opening 05, ensuring that external air can only enter the system through the ventilation holes 06 on the hole plate 02. This design helps to concentrate the control of airflow, preventing dust and impurities from bypassing the filter cotton 03 and directly entering the system, improving the filtering effect.

[0044] The cotton is firmly fixed on the ventilation opening 05 by the fixed plate 04 and fully covers the hole plate 02. In this way, when air enters the system through the ventilation holes 06, the wind force will act uniformly on the entire surface of the filter cotton 03. This uniform stress distribution helps to prevent the filter cotton 03 from being subjected to excessive wind force impact locally, reducing the risk of damage to the filter cotton 03.

[0045] Due to the uniform wind force acting on the filter cotton 03 as a whole, the local stress concentration of the filter cotton 03 when subjected to wind force impact is reduced. This helps to prevent damage to the filter cotton 03 caused by uneven stress, improving the service life and performance stability of the filter cotton 03.

[0046] The design of the hole plate 02 and the full coverage of the filter cotton 03 ensure that the wind force distribution inside the entire system is optimized. By uniformly transmitting wind force to the surface of the filter cotton 03, the system more effectively utilizes wind force, improving the ventilation effect.

[0047] In an alternative embodiment, the fixed plate 04 is connected to the hub body 01 in a detachable manner.

[0048] In alternative embodiments, the connection between the fixed plate 04 and the hub body 01 is detachable, meaning that the fixed plate 04 can be easily installed and removed, providing a more flexible maintenance and replacement of the filter cotton 03. The following is a detailed description of this feature:

[0049] Threaded connection: The detachable connection between the fixed plate 04 and the hub body 01 can adopt a threaded structure. The threads on the fixed plate 04 match the corresponding threads on the hub body 01, and by rotating the fixed plate 04, connection and disconnection can be easily achieved. This design makes the installation and maintenance process more convenient.

[0050] Snap-on connection: Another way of detachable connection is to use a snap-on structure. The hub body 01 and the fixed plate 04 are respectively designed with corresponding buckles, which can be firmly connected or easily disconnected through simple insertion or pressing operation. This way is more convenient and fast.

[0051] Latch connection: The detachable connection can also be achieved through a latch. The hub body 01 and the fixed plate 04 are respectively designed with corresponding holes and slots, and the connection and disconnection process can be completed by inserting or pulling out the latch.

[0052] Spring pin connection: Using spring pins or quick-lock pins as connecting elements, the connection between the fixing plate 04 and the hub body 01 can be easily connected and disassembled by pressing or twisting the lock pin.

[0053] In an optional embodiment, the ventilation holes 06 are arranged in a circular ring pattern on the hole plate 02.

[0054] In this optional embodiment, the ventilation holes 06 are designed in a circular ring pattern, which may have some specific advantages. The following is a detailed description of this optional embodiment:

[0055] The circular ring arrangement of the ventilation holes 06 can promote the uniform distribution of air on the hole plate 02. This helps to ensure that the entire surface of the ventilation opening 05 can fully participate in the ventilation process, improving the ventilation effect.

[0056] The circular ring arrangement of the ventilation holes 06 may have better performance in terms of airflow dynamics. This arrangement can reduce resistance and improve the efficiency of air flow through the ventilation holes 06, thereby achieving more effective ventilation.

[0057] The circular ring arrangement of the ventilation holes 06 can better adapt to different air flow rates. This is because the circular ring arrangement of the ventilation holes 06 can more evenly distribute wind power, reducing local wind speed differences.

[0058] In an optional embodiment, a dustproof sealing ring 07 is provided between the fixing plate 04 and the hub body 01 to prevent dust and contaminants from entering the hub body 01.

[0059] In this optional embodiment, a dustproof sealing ring 07 is designed to prevent dust and contaminants from entering the hub body 01, which is located between the fixing plate 04 and the hub body 01. The following is a detailed description of this optional embodiment:

[0060] The dustproof sealing ring 07 is placed at the joint between the fixing plate 04 and the hub body 01 to form an effective barrier. The sealing ring tightly fits the surface of the fixing plate 04 and the hub body 01 to ensure that dust cannot enter the hub body 01 through the gap in the connection part.

[0061] The dustproof sealing ring 07 can be made of elastic materials such as rubber or silicone. Such materials have compressibility and can form an effective seal at the connection part, while also having certain wear resistance to adapt to long-term use environments.

[0062] The dustproof sealing ring 07 is designed to completely surround the connection part, ensuring that the entire periphery of the connection is protected from dust. This design helps to minimize the risk of dust and contaminants entering the system.

[0063] The material of the dust seal 07 can have resistance to chemical corrosion to adapt to different working environments that can exist, such as conditions of humidity or corrosive gases.

[0064] The addition of the dust seal 07 not only serves to prevent dust from entering the hub body 01, but also enhances the overall sealing of the connection. This helps to prevent the effects of moisture or other environmental conditions on the connection.

[0065] By providing the dust seal 07, the reliability of the system is improved as it effectively reduces the probability of potential problems arising from dust and contaminants entering the hub body 01.

[0066] In an optional embodiment, the fixed plate 04 is provided with a tension adjustment structure 08 for adjusting the tension of the filter cotton 03.

[0067] In an optional embodiment, the tension adjustment structure 08 includes a rotating rod 09, a rotating head 10, and a ratchet assembly 11. The rotating rod 09 is rotatably connected to one side of the fixed plate 04, the edge of the filter cotton 03 is fixed to the rotating rod 09, the rotating head 10 is installed at one end of the rotating rod 09, and the ratchet assembly 11 is provided on the rotating head 10.

[0068] In this optional embodiment, the tension adjustment structure 08 is introduced on the fixed plate 04 to adjust the tension of the filter cotton 03. The following is a detailed description of this embodiment:

[0069] Rotating rod 09: The rotating rod 09 is the main part of the tension adjustment structure 08, one end of which is connected to one side of the fixed plate 04 to ensure its stable fixation in the system. The rotating rod 09 can rotate around its axis.

[0070] Edge fixation of filter cotton 03: The edge of the filter cotton 03 is fixedly connected to the rotating rod 09. Through this connection, the tension of the filter cotton 03 can be changed by adjusting the position of the rotating rod 09. This design is simple and effective, allowing adjustment without replacing the filter cotton 03.

[0071] Rotating head 10: The rotating head 10 is installed at one end of the rotating rod 09, serving as a connection between the fixed plate 04 and the rotating rod 09.

[0072] Ratchet assembly 11: The ratchet assembly 11 is provided on the rotating head 10 and can include a ratchet or gear. These gears, through the movement of the rotating head 10, provide a controllable, segmented adjustment mechanism for changing the tension of the filter cotton 03.

[0073] Adjusting the tension of the filter cotton 03: By rotating the rotating rod 09, the rotating head 10 and the ratchet assembly 11 move together, changing the fixed position of the filter cotton 03, thereby adjusting the tension of the filter cotton 03. This adjustment structure can fine-tune the tension as needed without replacing the filter cotton 03.

[0074] The design of the tension adjustment structure 08 allows the operator to easily adjust the tension of the filter cotton 03 without the need for complicated operations or additional tools.

[0075] In an optional embodiment, the shape of the air vent 05 is circular.
