Abstract

The utility model discloses an improved structure of an electric fan, which relates to the technical field of electric appliances. The utility model comprises an outer shell with an air inlet, wherein the lower end of the outer shell is provided with a motor which drives a wind drum in the middle part of the outer shell, and the upper end is provided with a control box; the outer shell is provided with two air outlets which mutually form an intersection angle. Since the outer shell of the fan is provided with the two air outlets which mutually form the intersection angle, and a blowing angle of the utility model, which can reach 180 DEG, is far in excess of the blowing angle of the traditional fan. The utility model can improve the problem of small blowing range of the fan so that people who are in different directions beside the fan can enjoy the cool wind blown from the fan.

Description

A kind of electric fan structure-improved

Technical field:

The utility model relates to technical field of electric appliances, especially relates to a kind of electric fan for indoor use.

Background technique:

Electric fan is compared air-conditioning and is had the characteristics of energy-conserving and environment-protective and extensively adopt for people institute in the weather sweltering heat.Domestic electric fan in the market is of a great variety, differs from one another.But most electric fan is only exhaust outlet air-supply of tool all, and the angular range that wind blew is less, during use, and the problem that exists some of the staff to be blown to, rather inconvenience.Though and some Industrial fan has blowing angle big characteristics, it exists also that volume is big, energy consumption is high, noise is big and shortcoming such as potential safety hazard is arranged, and is difficult to be applicable to ordinary family and general office space.

The model utility content:

The purpose of this utility model provides a kind of electric fan structure-improved with regard to being the deficiency that exists at prior art, to solve the existing little problem of domestic electric fan blowing range.

For achieving the above object, the utility model comprises the shell with an intake grill, and the shell lower end is provided with the motor of the wind drum that drives the shell middle part, and the upper end then is provided with Direct box, and shell has two exhaust outlets that are mutually angle.

The shell internal fixation has three wind deflectors, and wherein, first wind deflector is concave arc shape, and its length extends to bonnet from protecgulum, and second wind deflector and the 3rd wind deflector then are convex arc shaped, and its length is shorter; Form intake grill and two exhaust outlets that are mutually angle between the protecgulum of three wind deflectors and shell.

Be fixed with the protective net grid on the described exhaust outlet respectively.

The lower end of shell also is provided with by synchronous machine and the rotating mechanism that is made of the synchronous rotating disk of synchronous machine drives, and wherein, rotating disk is fixed on the protecgulum and bonnet of shell synchronously.

Described synchronous machine is fixed on the tuner, and tuner then links to each other with a base disk by supporting vertical rod.

Described two exhaust outlets are the angle of 70～100 degree.

Favourable beneficial effect of the present utility model really is: owing to have two exhaust outlets that are mutually angle on the shell of fan, its wind direction can reach 180 degree, considerably beyond conventional fan, can improve the little problem of fan air-supply scope widely, make the people who is in the other different azimuth of fan all can enjoy the cool breeze that blows, effect is very good.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is a schematic appearance of the present utility model

Accompanying drawing 1 is an internal structure schematic representation of the present utility model

Accompanying drawing 3 is that the A-A of accompanying drawing 2 is to sectional view

Embodiment:

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

See that accompanying drawing 1 is to shown in the accompanying drawing 3: electric fan of the present utility model has a shell 10 that is made of protecgulum 101 and bonnet 102, shell 10 middle parts are provided with a wind drum 30, shell 10 lower ends are provided with the motor 20 that is fixed on the electric machine support 21, the rotating shaft of motor 20 links to each other with wind drum 30 lower ends, and the upper end of wind drum 30 then links to each other with the bearing 31 at shell 10 tops.After motor 20 starts, can drive wind drum 30 and rotate, to finish air intake and air-supply action.

The upper end of shell 10 is provided with Direct box 40, Direct box 40 internal fixation have parts such as circuit board 41, control knob 42, Direct box bottom 43, be mainly used in the power supply, air quantity of control electric fan, regularly, yaw, provide negative ion etc., its structure can be seen on existing electric fan, by those skilled in the art are familiar with, repeat no more here.

Shell 10 internal fixation have three wind deflectors 103,104,105, and wherein, first wind deflector 103 is concave arc shape, and its length extends to bonnet 102, the

second wind deflectors

104 and 105 of the 3rd wind deflectors are convex arc shaped from protecgulum 101, and its length is shorter; Form intake grill 11 and two

exhaust outlets

12,13 that are mutually angle between the protecgulum 101 of three wind deflectors 103,104,105 and shell 10, the bonnet 102.Exhaust outlet 12 and angle effect when 70～100 spend of 13 are preferable, are best when 90 spend.Be fixed with protective net grid 121,131 on the

exhaust outlet

12 and 13 respectively, enter in the shell 10 to prevent foreign matter.

The lower end of shell 10 also is provided with the rotating mechanism that is made of synchronous machine 50 and the synchronous rotating disk 60 that driven by synchronous machine 50, and wherein, rotating disk 60 is fixed on the protecgulum 101 and bonnet 102 of shell 10 synchronously.After synchronous machine 50 started, rotating disk 60 can drive fan and do the yaw action synchronously, with further increase blowing range.

In addition, synchronous machine 50 lower ends also are fixed with tuner common on the vertical fan 70, and this tuner 70 links to each other with support vertical rod 80, to support and to regulate the height of fan, the lower end of supporting vertical rod 80 then links to each other with base disk 90, and base disk 90 is placed on the ground, is used for the weight of balance fan.

Certainly, except the structural type that the foregoing description is mentioned, electric fan of the present utility model also can be according to user's actual demand, and the shape of shell and exhaust outlet is changed accordingly, two exhaust outlets both can be position, left and right sides relation, and also front and back position concerns.In addition, the utility model except can be vertical, also can make desk-toply, hanging etc., its size also can be adjusted to form different series product.
