[0024] The various non-limiting embodiments of the utility model will be described in detail below with reference to the drawings.

[0025] Please refer to Figures 1-3 The utility model discloses a waterproof and dustproof fan wiring device, which comprises a wiring hole 2 formed on a fan body 1, a fixing block 4 for fixing a power cord 3 is embedded in the wiring hole 2 through a clamping structure, wherein,

[0026] The clamping structure comprises a first limiting protrusion 21 arranged on the inner side wall of the wiring hole 2 and a first limiting groove 41 arranged on the outer side wall of the fixing block 4 and matched with the first limiting protrusion 21; or,

[0027] The clamping structure comprises a second limiting groove arranged on the inner side wall of the wiring hole 2 and a second limiting protrusion arranged on the outer side wall of the fixing block 4 and matched with the second limiting groove.

[0028] In the embodiment, the fan wiring device is provided with a clamping structure in the wiring hole 2 of the fan body 1, and the fixing block 4 for fixing the power cord 3 is embedded in the wiring hole 2 through the clamping structure, thereby effectively solving the problem of insufficient sealing of the power cord interface of the existing fan, and achieving the waterproof and dustproof technical effect of the fan. Specifically, the first limiting protrusion 21 in the clamping structure is matched with the first limiting groove 41 or the second limiting groove (not shown in the figure) and the second limiting protrusion (not shown in the figure), so that the fixing block 4 can be tightly embedded in the wiring hole 2, thereby forming a sealed structure at the position where the power cord 3 passes out of the fan body 1. This design not only prevents dust from entering the fan interior through the wiring hole 2, but also effectively prevents water from entering, greatly improving the use safety and service life of the fan, and providing reliable protection for the stable operation of the fan in various environments.

[0029] Further, in one embodiment, the waterproof and dustproof fan wiring device, wherein the fixing block 4 is provided with a fixing hole 42 matched with the power cord 3, when the fixing block 4 is embedded in the wiring hole 2, the power cord 3 is connected with the circuit board 11 in the fan body 1 after passing through the fixing hole 42.

[0030] In the embodiment, a fixing hole 42 is formed in the fixing block 4 to match the power cord 3. When the fixing block 4 is embedded in the wiring hole 2, the power cord 3 is connected to the circuit board 11 in the fan body 1 after passing through the fixing hole 42. This design further enhances the fixing effect of the power cord 3, ensuring that the power cord 3 will not loosen or shift during fan operation due to vibration or external force, thereby improving the electrical connection stability of the fan. At the same time, the matching design of the fixing hole 42 and the power cord 3 makes the power cord 3 more tightly pass through the fixing block 4, further enhancing the sealing performance at the wiring hole 2, effectively preventing dust and moisture from entering the inside of the fan body 1 through the gap between the power cord 3 and the fixing block 4, thereby further ensuring the long-term stable operation and service life of the fan on the basis of improving the waterproof and dustproof performance of the fan.

[0031] Further, in one embodiment, the waterproof and dustproof fan wiring device, wherein the inside of the fixing hole 42 and the power cord 3 are filled with sealing glue.

[0032] In the embodiment, the inside of the fixing hole 42 and the power cord 3 are filled with sealing glue, which further improves the sealing performance of the fan wiring device. The sealing glue can effectively fill the small gap between the power cord 3 and the fixing hole 42, forming a tight sealing layer, thereby more thoroughly preventing dust and moisture from entering. This double sealing measure (tight embedding of the clamping structure and filling of the sealing glue) not only ensures the stable connection of the power cord 3 at the wiring hole 2, but also greatly enhances the waterproof and dustproof ability of the fan, enabling the fan to operate normally in a more severe environment, significantly improving the reliability and service life of the fan, and providing users with a safer and more stable product experience.

[0033] Further, in one embodiment, the waterproof and dustproof fan wiring device, wherein the fixing block 4 is made of rubber or silicone material.

[0034] In the embodiment, the fixing block 4 is made of rubber or silicone material, which has important technical effects in many aspects. First, the rubber and silicone material has good elasticity and softness, which can make the fixing block 4 better fit the inner side wall of the wiring hole 2 when being embedded in the wiring hole 2, further enhance the sealing effect, and effectively prevent dust and moisture from entering the fan through the gap between the fixing block 4 and the wiring hole 2. Second, the two materials also have certain anti-aging and corrosion resistance, which can maintain stable physical properties under different environmental conditions and prolong the service life of the fixing block 4, thereby ensuring long-term reliable operation of the fan wiring device. In addition, the rubber and silicone material has good insulation performance, which can effectively prevent short circuit and other electrical faults between the power cord 3 and the fan body 1, and improve the safety of the fan. That is, the fixing block 4 made of rubber or silicone material in the embodiment not only improves the waterproof and dustproof performance of the fan, but also enhances the safety and stability of the electrical connection, providing a strong guarantee for the efficient and stable operation of the fan.

[0035] Based on the waterproof and dustproof fan wiring device provided in the above embodiment, another embodiment of the utility model also provides a axial fan, wherein the axial fan comprises the waterproof and dustproof fan wiring device as described in any one of the above embodiments, and the specific description is as above, which will not be repeated here.
