Abstract

A portable fan is made up of a machine body and a machine head. The machine body comprises a casing, a motor arranged in the casing, a battery box and a charging interface; the machine head comprises a blade connected to the main shaft at the front end of the motor and a V-shaped air guide shade sleeved at the front part of the casing. The fan adopts the technical scheme that the V-shaped air guide shade is sleeved at the front part of the casing and a hook is arranged at the middle part of the casing, so as to solve the problem that the existing fans in various kinds is inconvenient for carrying, has no air guide and collection device, and can not be suspended to clothes carriers, etc.. The portable fan is suitable to serve as a summer heat-eliminating and cooling tool for workers in hot environment.

Description

Portable fan

Technical field

The utility model relates to a kind of portable fan.

Background technique

Existing commercially available all kinds of fans are all fixed, volume carries than big and inconvenience, and existing micro fan all is not suitable for being engaged in labourer's use of working under the high thermal environment of high temperature, can not satisfy the demands of consumers, and it can not satisfy the requirement of enjoying the cool of driving away summer heat that numerous labourers work dragon under hot environment.

Summary of the invention

At above-mentioned situation, the purpose of this utility model is to provide a kind of portable fan, and it had been both simple in structure easily makes, esy to use, safe and reliable again, also can hang on the clothing carrier, and cost is low, is convenient to penetration and promotion.

To achieve these goals, a kind of portable fan, it is made up of fuselage, head, fuselage comprises casing, be arranged at motor, battery case and charging inlet in the casing, head comprises fan blade that connects motor front end main shaft and " V " type wind scooper that is set in the casing front portion.

For implementation structure optimization, its further step is:

Hook is established at the middle part of casing.

The afterbody of casing is established ventilated port.

The utility model adopts the technological scheme of establishing hook at anterior suit " V " the type wind scooper of casing and casing middle part, has overcome existing all kinds of fan inconvenience and has carried and do not have the wind-guiding wind-gathering device, can not hang on the first-class defective of clothes carrier.

The beneficial effect that the utility model is produced compared to existing technology:

(I) adopt " V " type wind scooper, wind can be assembled the back and directly act on human body in the useful direction derivation, it is faster, better to dispel the heat, and reduces the probability that labourer suffers heatstroke under high temperature, high thermal environment.

(II) the light volume of product is little, and the casing rear portion is equipped with hook and can be hung on easily between waist on the clothing carrier such as belt directly to human body blowing heat radiation, good heat dissipation effect.

(III) use high-speed permanent magnet motor, rotating speed is fast, noise is low, and adopts the vortex type impeller of 8 above fan blades, and wind-force is bigger, and heat radiation is relieved summer heat effective.

(IV) simple in structure, compactness is made simply, and cost is low, is convenient to penetration and promotion.

The utility model is fit to do the instrument of enjoying the cool that drives away summer heat of labourer under the hot environment.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the plan view of Fig. 1.

Among the figure: 1, motor, 2, casing, 3, battery case, 4, charging inlet, 5, fan blade, 6, " V " type wind scooper, 7, hook, 8, ventilated port, 9, screw, 10, switch.

Embodiment

Referring to accompanying drawing, a kind of portable fan, it is made up of fuselage, head.Fuselage comprises motor 1, battery case 3, charging inlet 4 and casing 2, battery case 3 is socketed on the rear end of motor 1 and is arranged at casing 2 central authorities, charging inlet 4 is connected with battery case 3 and is arranged on casing 2 housings, with the charging inlet 4 adjacent switches 10 that are connected battery case 3 and motor 1 that are provided with, casing 2 two sides of tail housings are provided with ventilated port 8, and wherein a hook 7 is established in a side ventilated port 8 tops; Head comprises " V " type wind scooper 6 and fan blade 5, and " V " type wind scooper 6 is set on the casing 2 and through screw 9 and fixes, and fan blade 5 is connected on the motor 1 front end main shaft and is arranged in " V " type wind scooper 6.

When this portable fan of use, the user presses switch 10, and battery case 3 is immediately to motor 1 power supply, and motor 1 drives fan blade 5 rotations, to the human body air draft, is that motor 1 ventilation and heat to guarantee safe handling by ventilated port 8 through " V " type wind scooper 6.Owing to can be hung between waist on the belt through linking up with 7, recess is close between waist in " V " type of " V " type wind scooper 6, the wind-force that produces can directly act on user's upper body, make clothes and health separately, cooling is fast around the body surface, the clothes that then can better utilization wind-force blows open the labourer of outside work stops too much exposure in sunshine, makes health nice and cool comfortable, reduces labourer and works under the high thermal environment of high temperature the probability of heatstroke takes place.

For increasing wind-force, fan blade 5 adopts the vortex type impeller that is made of 8 above fan blades, fan blade 5 wind-force are increased, motor 1 noise is low, rotating speed is high in order to make, driving fan blade 5 rotates fast, motor 1 adopts the 4.5V high-speed permanent magnet motor, has further strengthened wind-force, can help labourer to dispel the heat to greatest extent and relieve summer heat.

For making the volume that reduces battery case 3, adopt compact type 4.5V chargeable cell, so product with compact structure, light, volume is little.

It below only is the utility model preferred embodiment, according to above-mentioned design of the present utility model, those skilled in the art can also make various modifications and conversion to this, as the conversion and the modification of battery case, motor and fan blade Placement etc., yet similar this conversion and modification all belong to essence of the present utility model.
