Abstract

The utility model discloses a portable electric fan, belonging to the domestic appliance class in the necessities of the daily life of the human, and is used for the heatstroke prevention in the hot season. The portable electric fan is mainly composed of a fan head and a hand-hold stem. The fan head is fixed and connected with the hand-hold stem by a fixed axle; the fan head can be converted from 0 DEG to 90 DEG around the fixed axle, and can generate the cool wind. The portable electric fan can adopt 1# dry battery, 2# dry battery and 5# dry battery. Compared with the common fan, the portable electric fan can reduce the labor intensity when the people fan to remove the summer heat and cool, and improves the heatstroke prevention effect. The portable electric fan is an ideal heatstroke prevention appliance for the family, the tour, and the work on errand. The portable electric fan has low cost.

Description

Portable electric fan

The utility model belongs to the household electric appliance in the human daily life necessity.

In the season of sweltering heat, reducing temperature of heatstroke prevention is human lives and physiological needs.In the past, people once used several different methods, and the various fans of commonplace use are exactly one of most important method wherein, and are handed down.In the modern times,, produced the reducing temperature of heatstroke prevention equipment of air-conditioning, electric fan and so on along with science and technology development.The general volume of these equipment is bigger, be comparatively speaking fix and be installed in indoorly, can not carry use.In fact, among the human lives, in hot day, there are considerable people and the considerable time need be outdoor, as when going out work, in the travelling way, the time of waiting ship time, be sitting in the common car and boat that do not start, all be quite sultry unbearably, and all do not have air-conditioning and electric fan and so on reducing temperature of heatstroke prevention equipment mostly.With common fan pectinid, though can get cold, certain labor intensity is arranged, wind-force is less, and day hot more need fan faster just need be paid bigger labor intensity more soon, thereby also be made human body produce more heat, is unfavorable for preventing heatstroke and lower the temperature.

The purpose of this utility model is the defective and the deficiency of replenishing above-mentioned every prior art in order to overcome, provide that a kind of to have structure lightly exquisite, can carry, easy to use conveniently, soft nice and cool wind can be produced, and the novel handheld portable electric fan of the labor intensity of people when pectinid is got cold can be alleviated greatly.

Its concrete solution is:

(1), a fan head and handle are set, fan head and handle are connected and fixed with a stationary axle, and fan head can be rotated around handle, the angle of rotation is 0 °-90 °.Certainly, also can be designed as a housing, fan head and handle are two-part of same housing.

(2), fan head is made of fan head housing, motor and fan blade.Install at the front end of fan head housing and to expand air regulator, expansions air regulator is curvilinear body (as a hemisphere), on the wind of expansion hole is arranged, like this, wind-force is spread with fan-shaped, help enlarging people's blowing area, increase the effect of preventing heatstroke and lower the temperature; Rear end at the fan head housing is provided with air inlet window, and inlet hole is arranged on it; In the fan head housing, settle motor, on the arbor of motor, fan blade is installed.

(3), handle is made of handle housing and battery.Be equipped with on the handle housing that power supply is extreme, switch and bonnet, in the handle housing, settle battery.Single grade on switch, or size many grades and that can control electric current change rotating speed of motor, thereby adapt to the needs of people to different air quantity sizes.

(4),, motor extreme by battery, power supply and switch constitute a working current loop by the conductive metal wire plate in body, open and close power supply by switch control.

(5), fan head and handle available metal or plastics make, but its external shape garden shape, square, prismatic and ellipse garden shape.

After having taked above-mentioned measure, enable switch, motor is promptly started working, and drives fan blade and rotates, produce nice and cool pleasant wind, and spread out with fan-shaped from expanding air regulator, increase people's blowing area, improve the reducing temperature of heatstroke prevention effect, because fan head can change direction, switch is the size of adjustable wind-force again, therefore, can adapt to the needs of people to different use angles and air quantity size.

Obviously, the handheld portable electric fan made of principle thus, it is little to have volume, characteristics in light weight, that air quantity is big, efficient is high, and the labor intensity can alleviate people's pectinid greatly and get cold the time, improve the effect of reducing temperature of heatstroke prevention, convenient abundant the living in hot season of people of having beautified, hand-held such handheld portable electric fan uses, and is new and enjoyment U.S. in fact.

Further specify the formation of its most preferred embodiment below in conjunction with accompanying drawing.

Accompanying drawing 1 is a whole front elevation of the present utility model, and accompanying drawing 2 is a whole profile of the present utility model.Label same section content shown in it is also identical in accompanying drawing 1 and the accompanying drawing 2.Accompanying drawing 1 and accompanying drawing 2 are shown in the different amount of same handheld portable electric fan, reference mutually.(1) is fan head among the figure, and (2) are handle, and fan head (1) and handle (2) are connected to one by stationary axle (9).Fan head (1) can carry out 0 °-90 ° angular transition around axle.Fan head (1) is made of fan head housing (13), motor (10) and fan blade (6).The expansion air regulator (7) that the front end of fan head housing (13) is installed be curvilinear body (as a hemisphere), on the wind hole (8) of expansion is arranged, the wind-force by fan blade (6) generation is spread with fan-shaped; On the air inlet window (11) that install the rear end of fan head housing (13) inlet hole (12) is arranged; Install and fix in the fan head housing (13) on the arbor of motor (10), motor (10) and install and fix fan blade (6).Handle (2) is made of handle housing (14), battery (4).Power supply extreme (3), bonnet (15) and switch (5) are arranged on the handle housing (14); Can settle battery (4) in the handle housing (14), the number of model, quantity and the power supply of battery (4) extreme (3) is needed to decide by design.Single grade on switch (5), or the size of many grades can regulate electric current, control rotating speed of motor, thereby the size of adjustable air quantity.The utility model is by battery (4), and power supply is (3) extremely, and motor (10) and switch (5) constitute a working current loop by the conductive metal wire plate in body, opens and closes power supply by switch control.

The utility model sample is trial-produceed successfully, has that volume is little, in light weight, a delicate structure, efficient height, and the characteristics that air quantity is big can be easy for people to use, greatly alleviates the labour intensity of people when pectinid is got cold, improves the effect of reducing temperature of heatstroke prevention. Because the utility model is simple in structure, processing technology and raw material all do not have specific (special) requirements, easily practice and extension.
