Abstract
The utility model relates to the field of small fans, in particular to a novel universal serial bus (USB) fan with aluminum fan blades and a brushless electric machine. The novel USB fan with the aluminum fan blades comprises a back cover and a front cover, wherein the brushless electric machine is installed on the back cover, four aluminum fan blades are installed in front of the brushless electric machine, and a support frame is fastened on two sides of the back cover through screws. The fan blades are replaced into the four aluminum fan blades from existing three plastic products or iron products, and shaking and noise generated in operation of the fan are greatly reduced. A USB interface is used as a power interface, the connection mode of a power supply is convenient, and the fan can be used through the USB interface of a computer and also can be used through a socket of a mobile phone charger. The novel USB fan with the aluminum fan blades is simple in structure, reasonable in design and convenient to use, and occupies little space when placed on an office table or beside the computer.
Description
Technical field
The utility model relates to the small-sized fans field, particularly a kind of novel aluminium flabellum USB fan that adopts brushless electric machine.
Background technique
Along with the improvement function with charger for mobile phone of popularizing of computer, the product that has USB interface more and more receives people's welcome, connects the indispensable interface of external equipment in USB has become; The desk-top small fan that is used on the Office table in the past all has a simple fixed support, and the contact desktop be exactly several bare little poles, the earth-grasping force that has no; Not very steady when wind increases; Mostly flabellum is three plastics and iron work, and trembling of producing during fan work is very big, and noise is also very big; In order to overcome existing issue, the utility model is primarily aimed at and improves flabellum, power interface and stability.
Summary of the invention
The purpose of the utility model is in order to overcome the defective that existing small fan exists, to invent a kind of brushless electric machine and novel aluminium flabellum USB fan that adopts four aluminum flabellums of adopting.
The purpose of the utility model realizes as follows: said a kind of novel aluminium flabellum USB fan; Comprise back cover and front shroud; Brushless electric machine is housed on back cover, and four aluminum flabellums are equipped with in the front of brushless electric machine, are fastened with support on the both sides of back cover with screw.
Said support is fastening and be provided with the support pad that rubber is made through screw.
The back of said back cover is provided with the fan work switch.
Said front shroud is to use screw to be connected with back cover and is fixing.
Said power supply inlet opening is arranged on the back of back cover, and power line gets in the inner brushless electric machine through the power supply inlet opening, and USB interface is adopted in the other end of power line.
The good effect of the utility model is following: flabellum changes four aluminum flabellums into by existing three plastic article or ferrous products, greatly reduces fan trembling and noise of producing of when work.Power interface adopts USB interface, has made things convenient for the Placement of power supply, can be through the USB interface of computer; Also can use fan through the socket of charger for mobile phone, the utility model is simple in structure, and is reasonable in design; Easy to use, be placed on Office table or computer next door and do not take up space.
