Detailed Description
In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
Examples
Fig. 1 is a schematic overall structure diagram of an industrial fan according to an embodiment of the present invention. Fig. 2 is a partially enlarged schematic view of the industrial fan shown in fig. 1. Fig. 3 is a schematic view of a partial structure of the special-shaped absorbent cotton according to an embodiment of the present invention. An industrial fan with noise reduction on fan blades comprising: boom 10, motor housing 11, motor 12, turntable 14, fan blades 15, and outer diffuser 21. A motor housing 11 is arranged below the suspension rod 10. The motor 12 is disposed in the motor housing 11, and a turntable 14 is disposed below a driving shaft 13 thereof. A plurality of fan blades 15 are uniformly arranged around the rotary table 14. An external diffuser 21 is provided at the tip of each fan blade 15. The motor case 11 is provided with a graphite heat dissipation film 16. The graphite heat dissipation film 16 is spirally disposed on the motor case 11. A mosquito repellent box 17 is also arranged in the motor shell 11. The mosquito repellent liquid box 17 is filled with mosquito repellent liquid 19, and the bottom of the mosquito repellent liquid box is provided with a small hole (not shown in the figure). The diameter of the small hole satisfies that the dripping speed of the mosquito repellent liquid 19 is slightly less than the volatilization speed of the mosquito repellent liquid 19. In a preferred embodiment, the small holes are arranged in a size-adjustable structure, so that the small holes can be adjusted as required in high-temperature weather and medium-high temperature weather to adapt to the volatilization speed of the current mosquito repellent liquid 19. The mosquito repellent liquid 19 is led out from the mosquito repellent liquid box 17 through liquid absorbing cotton, wherein the liquid absorbing cotton is arranged on the graphite heat dissipation film 16. The absorbent cotton comprises a plurality of elongated connecting parts 20 and a plurality of circular liquid storage parts 18, the circular liquid storage parts 18 are arranged at intervals, and the elongated connecting parts 20 are arranged between the adjacent circular liquid storage parts 18. Wherein, the diameter of the circular liquid storage part 18 is 0.4 to 0.5 times of the width of the graphite heat dissipation film 16, and the width of the slender connecting part 20 is 0.1 to 0.2 times of the diameter of the circular liquid storage part 18. Tests show that when the diameter of the circular liquid storage part 18 is 0.4-0.5 times of the width of the graphite heat dissipation film 16, and the width of the slender connecting part 20 is 0.1-0.2 times of the diameter of the circular liquid storage part 18, the heat dissipation effect of the motor 12 and the evaporation speed of the mosquito repellent liquid 19 are well balanced, meanwhile, the cost of liquid absorption cotton can be reduced, and the appearance of the fan is better.
The industrial fan of the utility model is provided with the graphite heat dissipation film 16 on the motor shell 11; still be provided with mosquito repellent box 17 in the motor casing 11, mosquito repellent 19 draws forth in inhaling cotton self-driving mosquito repellent box 17 of liquid, and wherein inhale the cotton setting of liquid on graphite heat dissipation membrane 16, can effectively dispel the heat to the motor of industrial fan, utilizes the heat to inhale mosquito repellent 19 on the liquid cotton simultaneously, and the structure is ingenious, and mosquito repellent is effectual. By adopting the special-shaped absorbent cotton, the heat dissipation effect of the graphite heat dissipation film 16 can be ensured, and the evaporation of the mosquito repellent liquid 19 can be ensured. The outer-expanding flow collector 21 is arranged at the tail end of the fan blade 15, so that the vortex at the tail end of the fan blade 15 can be eliminated, the noise reduction effect is achieved, and meanwhile, the airflow direction can be changed, so that the airflow diffusion area is increased.
Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
