Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a novel fan with reinforcing ribs. Background Art

[0002] An electric fan, also known as a fan or blower, is a household appliance that uses an electric motor to drive the blades to rotate to accelerate the circulation of air. It is mainly used for cooling and circulating air. It is widely used in homes, offices, shops, hospitals, hotels and other places. The fan is mainly composed of parts such as the fan head, blades, mesh cover and control device. The fan head includes a motor, front and rear end covers and a shaking air supply mechanism.

[0003] However, in the prior art, most fan blades will frequently resonate when rotating at high speed, causing the fan to produce additional wear and additional noise, which affects the user experience. Long-term resonance will directly reduce the service life of the fan.

[0004] Therefore, the utility model provides a novel fan with reinforcing ribs to solve the above problems. Utility Model Content

[0005] The utility model provides a new type of fan with reinforced ribs, which aims to solve the problem proposed in the background technology that most fan blades in the existing technology will frequently resonate when rotating, causing the fan to produce additional wear and additional noise, which will affect the user experience, and long-term wear will directly affect the service life of the fan.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a new type of fan with reinforcing ribs, including a fan hub, a plurality of fan blades fixedly connected to the outer surface of the fan hub, a plurality of airfoil reinforcing ribs for reducing resonance fixedly connected between the fan blades, and a connecting disk fixedly connected to the inside of the fan hub.

[0007] As a preferred technical solution of the present application, the outer wall of the connecting disk is fixedly connected with a reinforcing rib, and one end of the reinforcing rib away from the connecting disk is fixedly connected to the inner wall of the fan hub.

[0013] Beneficial effects

[0014] The utility model arranges a fan hub, fan blades and airfoil-shaped reinforcement ribs. When the fan motor drives the fan hub to rotate using the output shaft, the fan hub can drive multiple fan blades to rotate, so that the output of air volume provided by the multiple fan blades when rotating can dissipate heat to the air outlet area in which they are located, and the airfoil-shaped reinforcement ribs connected between the multiple fan blades ensure that the fan blades have good stability when rotating. The multiple airfoil-shaped reinforcement ribs are used to provide connection and fixing points between the multiple fan blades to reduce the vibration generated when the multiple fan blades rotate, thereby achieving the purpose of reducing noise. This structure makes it difficult for the fan blades to generate frequent resonance when rotating at high speed, which can effectively reduce the extra wear and noise generated by the fan blades, preventing loud noise from affecting the user experience, and the more stable fan blades can effectively increase the service life of the fan.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a new type of fan with reinforcing ribs, such as Figure 1-6 As shown, the fan includes a fan hub 1, a plurality of fan blades 2 are fixedly connected to the outer surface of the fan hub 1, a plurality of airfoil reinforcement ribs 3 for reducing resonance are fixedly connected between the fan blades 2, and a connecting disk 4 is fixedly connected to the inside of the fan hub 1.

[0025] When the fan hub 1 is driven by the motor output shaft to rotate, the fan hub 1 can drive the multiple fan blades 2 to rotate, so that the air volume generated by the rotation of the fan blades 2 can dissipate the air volume to the air outlet area in which the fan blades 2 are located, so as to achieve the purpose of cooling the air outlet area, and the multiple airfoil reinforcement ribs 3 connected between the multiple fan blades 2 provide the fan blades 2 with a certain strength, and the multiple airfoil reinforcement ribs 3 provide the multiple fan blades 2 with connection fixing points, so that when the fan blades 2 rotate, they are similar to an integrated type and are not easy to resonate. While reducing the resonance, the noise generated when the fan blades 2 rotate can be effectively reduced, and at the same time, the wear of the fan hub 1 can be effectively reduced, thereby increasing the service life of the fan.

[0026] A reinforcing rib 5 is fixedly connected to the outer wall of the connecting disk 4 , and one end of the reinforcing rib 5 away from the connecting disk 4 is fixedly connected to the inner wall of the fan hub 1 .

[0027] The reinforcing ribs 5 provide the fan hub 1 with a certain strength support, so that the fan hub 1 is not easily deformed after a long period of rotation, thereby improving the service life of the fan hub 1. The fan hub 1 that is not easily deformed can reduce the number of collisions with the motor shaft, so that when the number of collisions is reduced, the noise generation can be further reduced. At the same time, the fan hub 1 that is not easily deformed can ensure that the multiple fan blades 2 connected thereto can smoothly generate air volume to cool the surrounding area, and prevent the fan blades 2 from changing angles following the deformed fan hub 1 so that it is difficult to generate wind force, thereby providing a better user experience.

[0028] A through hole 6 is formed inside the fan hub 1 , and an air guide block 7 is fixedly connected to the inside of the fan hub 1 within the through hole 6 .

[0029] The through hole 6 provides a flow point for the air flow, so that part of the air provided by the fan blades 2 can flow smoothly toward the motor, and the air flowing through the through hole 6 can be guided by the oblique air guide block 7, so that the air can be blown smoothly toward the motor to achieve the purpose of cooling the motor, thereby improving the ability of this device to be used continuously and effectively improving the service life of this device.

[0030] The air guide block 7 is inclined, and a reinforcing blade 14 is fixedly connected to the fan blade 2.

[0031] The reinforced blades 14 make the fan blades 2 have higher strength, so that when the fan blades 2 are fanning for a long time, the fan blades 2 are less likely to deform, preventing the fan blades 2 from deforming and reducing the air output, affecting the production of air volume, thereby ensuring the air output performance of the fan blades 2 and improving the service life of the fan blades 2.

[0032] A first protective cover 8 is provided on the outside of the fan hub 1, and a second protective cover 9 is provided on one side of the first protective cover 8. The outer wall of the first protective cover 8 is fixedly connected to a first inclined surface block 10, and the outer wall of the second protective cover 9 is fixedly connected to a second inclined surface block 11. The interior of the second inclined surface block 11 is slidably connected to a block 12, and a slot 13 for inserting the block 12 is provided on one side of the first inclined surface block 10.

[0033] The first protective cover 8 and the second protective cover 9 are brought close to each other to the merged position, so that the first protective cover 8 drives the first inclined surface block 10 to contact the second inclined surface block 11 on the second protective cover 9, and when the first inclined surface block 10 and the second inclined surface block 11 are adapted to each other, the first inclined surface block 10 can be squeezed by the inclined surface of the second inclined surface block 11 to achieve a slight upward movement, so that the first inclined surface block 10 can smoothly move to the inner side of the second inclined surface block 11 to form a clamping state, so as to achieve the purpose of installing the first protective cover 8 and the second protective cover 9, preventing the first protective cover 8 and the second protective cover 9 from separating, and when the first inclined surface block 10 and the second inclined surface block 11 are clamped , you can toggle the block 12 so that the block 12 can be stuck in the slot 13 on one side of the first bevel block 10 by sliding with the second bevel block 11 to prevent the first protective cover 8 and the second protective cover 9 from rotating, thereby avoiding the first protective cover 8 and the second protective cover 9 from rotating and causing the first bevel block 10 and the second bevel block 11 to fail, thereby ensuring the installation stability between the first protective cover 8 and the second protective cover 9, and the installation process is simple, without the need to tighten multiple bolts for installation, and disassembly is also convenient, and the above-mentioned middle slot 13 provides the block 12 with embedded space, so that when the block 12 is stuck in the slot 13, the last step of installation can be achieved.

[0034] Working principle:

[0035] When the output shaft of the motor drives the fan hub 1 to rotate, the fan hub 1 can drive the multiple fan blades 2 to rotate, so that the air volume emitted by the multiple fan blades 2 when rotating can cool the air outlet area in which they are located. At the same time, the airfoil reinforcement ribs 3 connected between the multiple fan blades 2 can improve the stability between the multiple fan blades 2 when rotating, and reduce the resonance of the fan blades 2 when rotating.

[0036] When it is necessary to install the first protective cover 8 and the second protective cover 9, first approach the first protective cover 8 and the second protective cover 9 to each other, so that when the first protective cover 8 drives the first inclined surface block 10 to contact the second inclined surface block 11 on the second protective cover 9, the first inclined surface block 10 can use the inclined surface to achieve oblique cooperation with the inclined surface of the second inclined surface block 11, so that when the first inclined surface block 10 is squeezed by the inclined surface of the second inclined surface block 11, one side of the first inclined surface block 10 can be smoothly pried upward slightly, prompting the first inclined surface block 10 to be smoothly moved to the top of the second inclined surface block 11, so that the first inclined surface block 10 can form a snap-fit state with the second inclined surface block 11, and at this time the block 12 can be pushed into the slot 13 to complete the final installation steps of the first protective cover 8 and the second protective cover 9.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
