Description

A kind of handset type fan

Technical field

The utility model relates to a kind of mini-fan more particularly to a kind of handset type fans.

Background technique

Hand drawing or hand-written report are the routine works of many people, but during hand-written, for a long time due to wrist Paper is contacted, the sweat flowed down is easy to soak paper.It draws if it is pencil, then will greatly affect drawing beauty, even It needs to do over again, such case often occurs in hidrosis crowd in hot weather.The miscellaneous bits on desktop and dust will affect simultaneously Paper cleanliness.

(patent No.: disclosing a kind of hand held miniature fan to Chinese utility model patent in 200420049170.0), leads to Crossing the weared on wrist structure set up is worn on fan directly on wrist, the trouble that need to be held when eliminating use.This knot Although the mini-fan of structure realizes hand and wears function, but still fall within toy one kind, and purposes is only limitted to blowing and enjoys the cool；Flabellum is exposed, Risk is big；Power supply needs button cell simultaneously, at high cost, pollution is big, is unable to satisfy multi-functional, safe and environment-friendly energy-efficient want It asks.

Utility model content

The purpose of this utility model is that in view of the above-mentioned problems, providing a kind of multi-functional, safety and environmental protection more function of handset type Energy mini-fan, the fan can be not only used for blowing sweat at summer wrist, it may also be used for blow away mince miscellaneous bits, dust and electronics and set It is standby cooling, it can also realize the function of supplying power for outside.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of handset type fan, including fan hub Body, hand wear shell, solar panel, it is characterised in that: it is long plate shape that hand, which wears shell, and blower-casting is cuboid, outside flabellum There is flabellum protective fence in face, and the air-flow that flabellum generates inside two blower-castings towards palm side, wear with hand by blower-casting upper end Shell is engaged by rack gear and is connected, and blower-casting flabellum protective fence side is known as lower end, passing through between two blower-castings Fixing belt elastic connection, the distance between two blower-castings are the width of wrist, i.e. wrist is located between two blower-castings, Fixing belt is located at wrist lower part, hand wears shell and is located at wrist top, and wrist lower part refers to that palm side, wrist top refer to the back of the hand one Side；Blower-casting includes motor, flabellum, and the flabellum protective fence of flabellum face is air outlet；It includes control circuit, electricity that hand, which wears shell, Energy storage device, USB input interface, USB output interface, (one is solar energy indicator light to two power on light, and one is outer Boundary's power supply indicator) and current-limiting resistance, the flabellum of fan be fixed on machine shaft, motor passes through conducting wire and current-limiting resistance, electricity It can storage device, control circuit connection forming circuit, electrical energy storage device and control circuit, power on light, solar battery Plate forms input circuit；Two conducting wires of USB input interface are connected to the positive and negative electrode of electrical energy storage device, USB input interface two A wherein conducting wire series connection external power supply display lamp in root conducting wire；Two conducting wires of USB output interface are connected to power storage The positive and negative electrode of device.

Fixing belt can select rubber belt or Velcro soft material.

After electrical energy storage device stores full electric energy, control circuit is opened, power on light is bright, and fan is started to work, and stirs It starts two sidewind of wrist, realizes the function of blowing sweat cooling；Need fan only need to be fan from hand when blowing away miscellaneous bits dust or refrigeration On remove, can be used directly to dry at this time.

The utility model has the beneficial effects that two fan airflow effects are good, flabellum protective fence, safety are installed outside flabellum additional Reliably, distance is adjustable between fan, adapts to the crowd of various wrist thicknesses, widely applicable, rectangular body case is conveniently laying, the sun Energy solar panel environmental protection and energy saving, USB input interface can be directly accessed power supply power supply, and guarantee can not utilize electricity when solar energy fill Supplying power for outside may be implemented in foot, USB output interface.The deficiency that existing mini-fan has a single function is compensated for, summer is used for, it can be with It is used to dry after blowing sweat to enjoy the cool；Sundries clast or the dust on paper or desktop can be blown away, can also be used to mobile phone Deng the electronic equipment cooling easily generated heat；Power supply uses sun-generated electric power and USB external power supply, environmental protection and energy saving；Electrical energy storage device It can will export electric energy supplying power for outside.
