Description

Technical Field

[0001] The utility model belongs to the technical field of heat dissipation fans, and in particular relates to a heat dissipation fan which is convenient for lubrication. Background Art

[0002] A cooling fan is a device used to assist equipment in dissipating heat and cooling down. It mainly accelerates air circulation to assist in cooling down various types of equipment or electronic components. Common cooling fans are mainly composed of a fan frame, rotor, fan blades, bearings and other accessories.

[0003] Since the cooling fan mainly accelerates air circulation to assist in heat dissipation and cooling, and the air inevitably contains dust, after a long period of use, the cooling fan's bearings will be affected by environmental factors such as dust or humid air, resulting in dry operation and abnormal noise. Therefore, it is necessary to regularly add lubricating oil to the cooling fan to ensure its stable operation.

[0004] In the prior art, most of the steps for lubricating the cooling fan are as follows: 1. tear off the label of the cooling fan; 2. use tweezers or other tools to open the buckle cover at the position where the label covers; 3. add lubricating oil to the buckle cover at the buckle position, so as to lubricate the cooling fan. This type of cooling fan not only requires the use of corresponding tools for lubrication, but also easily causes damage to the edge of the buckle cover when prying the buckle cover with tweezers or other tools, making the subsequent sealing effect of the buckle cover poor.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, a heat dissipation fan with convenient lubrication in one embodiment of the utility model includes: a fan frame 1, a fan component 2, and a split lubricating oil adding component 3.

The fan blade assembly 201 plays a role of assembling and limiting the rotor assembly 202.

[0031] like Figure 1 As shown, a rotor assembly 202 is rotatably mounted on one side of the fan blade assembly 201. The rotation of the rotor assembly 202 facilitates the air flow, thereby facilitating the device to dissipate heat by accelerating air circulation.

[0032] like Figures 1 to 3 As shown, the split lubricating oil adding assembly 3 is fixedly assembled on one side of the fan component 2, and the split lubricating oil adding assembly 3 includes an assembly fixing frame 301, and the assembly fixing frame 301 is fixedly assembled on the side of the fan blade assembly 201 away from the rotor assembly 202. The assembly fixing frame 301 plays a role in assembling and fixing the fan blade assembly 201.

[0033] like Figure 1 As shown, a sealing sticker 307 is attached to the side of the assembly fixing frame 301 away from the fan blade assembly 201, and the sealing sticker 307 is arranged in cooperation with the blocking screw cover 302. The sealing sticker 307 is convenient for the sealing screw cover 302 to be attached and limited. At the same time, the information parameters of the heat dissipation fan can be displayed through the sealing sticker 307.

[0034] Specifically, a lubricating oil adding hole is drilled in the assembly fixing frame 301, and the lubricating oil adding hole is arranged in cooperation with the fan blade assembly 201. It is convenient to add lubricating oil into the fan blade assembly 201 through the lubricating oil adding hole, so as to facilitate lubrication of the bearing in the fan blade assembly 201.

[0035] like Figures 2 to 4 As shown, the lubricating oil adding hole is threadedly connected with a plugging screw cap 302. The plugging screw cap 302 is used to seal and protect the lubricating oil adding hole.

[0036] like Figures 2 to 3 As shown, a sealing ring 308 is fixedly connected to one side of the plugging screw cap 302 located in the lubricating oil adding hole. The sealing ring 308 plays an auxiliary sealing role between the plugging screw cap 302 and the assembly fixing frame 301, reduces the situation where external dust or air enters the fan blade assembly 201, and improves the use stability of the fan blade assembly 201.

[0037] Preferably, the sealing ring 308 is a rubber sealing ring.

[0038] A receiving and avoiding groove is formed on the upper part of the sealing and rotating cover 302. The disassembly and assembly control member 309 is limited by the receiving and avoiding groove.

[0039] like Figures 2 to 4 As shown, a disassembly control member 309 is provided in the storage avoidance groove, and the disassembly control member 309 is hinged with the blocking rotary cover 302. It is convenient to disassemble and assemble the blocking rotary cover 302 by applying a force to the disassembly control member 309, which simplifies the convenience of disassembling and assembling the blocking rotary cover 302.

[0040] like Figures 2 to 3 As shown, a one-way flow guide tube 303 is fixedly connected inside the plugging rotary cap 302. The one-way flow guide tube 303 serves to connect the liquid adding hole with the flow guide cavity 311, so as to facilitate one-way flow of the lubricating oil to be added.

[0041] Specifically, a conical one-way flow guide hole is bored in the one-way flow guide pipe 303. The one-way flow guide pipe 303 is blocked and limited by the cooperation between the conical one-way flow guide hole and the blocking ball 305, thereby reducing the dust in the environment from entering the fan blade assembly 201.

[0042] like Figures 2 to 3 As shown, a side of the conical one-way flow guide hole close to the fan blade assembly 201 is fixedly connected to a limit filter 304. The limit filter 304 supports and limits the blocking ball 305 and the return spring 306.

[0043] like Figures 2 to 3As shown, a blocking ball 305 is arranged in the conical one-way flow guide hole. The movement of the blocking ball 305 controls the blocking and conducting state of the one-way flow guide tube 303.

[0044] like Figures 2 to 3 As shown, a return spring 306 is provided between the blocking ball 305 and the limiting filter screen 304. The contraction and return of the return spring 306 play a role of supporting and limiting the blocking ball 305.

[0045] Specifically, a liquid adding hole is drilled on one side of the sealing screw cap 302 outside the lubricating oil adding hole, and the liquid adding hole is arranged in cooperation with the one-way flow guide tube 303. It is convenient to add lubricating oil into the one-way flow guide tube 303 through the liquid adding hole.

[0046] like Figures 2 to 4 As shown, a sealing plug 310 is inserted into the liquid adding hole. The sealing plug 310 plays a role of sealing and protecting the liquid adding hole, reducing the blockage of the liquid adding hole caused by external dust.

The guide cavity 311 serves to connect the one-way guide pipe 303 with a plurality of oil drain holes 312, so as to evenly guide the lubricating oil guided by the one-way guide pipe 303.

[0048] like Figures 2 to 5 As shown, a plurality of evenly distributed oil drain holes 312 are drilled at one end of the plugging screw cap 302 located in the lubricating oil adding hole, and the oil drain holes 312 are arranged in cooperation with the fan blade assembly 201. The lubricating oil is diverted through the plurality of oil drain holes 312 to add lubricating oil to the fan blade assembly 201 at multiple angles.

[0049] In specific use, when lubricating oil needs to be added to the cooling fan, first tear off the sealing sticker 307, then take the sealing plug 310 to expose the liquid filling hole, and then continue to inject the lubricating oil into the one-way flow guide tube 303 in the liquid filling hole. As the lubricating oil is continuously injected, the sealing ball 305 compresses the return spring 306 under the action of liquid pressure. At this time, the lubricating oil in the liquid filling hole is injected into the fan blade assembly 201 along the one-way flow guide tube 303, the flow guide cavity 311 and the plurality of oil drain holes 312, thereby lubricating the bearings in the fan blade assembly 201.

[0050] At the same time, the blocking screw cap 302 can be driven to rotate by lifting the disassembly control part 309 and controlling the rotation of the disassembly control part 309, so as to separate the blocking screw cap 302 from the lubricating oil adding hole, and the lubricating oil can be added simultaneously.
