Abstract
The utility model provides a bladeless electric fan, consisting of a wind outlet device and a main body part, wherein the wind outlet device is a circular ring; the main body part forms a base; and the inside of the base comprises a brushless high-speed motor, an air channel, a turbine, an air inlet and a synchronous motor. The circular ring is shaped like a circular ring. The bladeless electric fan has safe use, convenient cleaning and low noise.
Description
Technical field
The utility model relates to the electric fan technical field, particularly a kind of no leaf electric fan.
Background technique
The electric fan that uses all is the blade that pectinid is arranged at present, and is both dangerous, takes again.The user need clean very bothersome for long-pending full dust on the cleaning flabellum.There is centre area " dead band " in traditional electric fan.The noise that the blade cuts air produces is also bigger.Unpeace disturbs daily life.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of no leaf electric fan is provided.
The working principle of no leaf electric fan:
It is that " blowing " comes out from the trickle wind groove of annulus centre that wind begins most: that very large annulus that the on-bladed fan heads on, be not to be amusement fully, but an important composition, its central authorities, opening the finedraw of one 1 mm wide, and wind just begins by the turbofan in the pedestal most, extracts base other air from producing by boasting here, it can pull ambient air, follow it to move together them, will produce a huge wind speed, together blowing forward.
A kind of no leaf electric fan, by going out wind apparatus and main body constitutes, going out wind apparatus is annulus, main body constitutes pedestal, comprises brushless high-speed electric expreess locomotive, air passageways, turbine, air intlet, synchronous machine in the pedestal.
The described annulus that goes out wind apparatus is a toroidal.
The described annulus that goes out wind apparatus is positioned at the top of pedestal.
In described pedestal, brushless high-speed electric expreess locomotive is installed in the top of pedestal, and the periphery of brushless high-speed electric expreess locomotive has the motor radiating hole.
Described air passageways lower end connects air intlet, and the upper end divides two ports to connect annulus, forms air passageways.
Described air passageways is in the outside of brushless high-speed electric expreess locomotive shell.
The anti-rubber that shakes is altogether arranged at the bottom of described brushless high-speed electric expreess locomotive.
Turbine is installed in the bottom of described brushless high-speed electric expreess locomotive, and the bottom of turbine is provided with air intlet.
Bottommost at described pedestal is provided with synchronous machine and motor driving plate and control circuit board.
Cross section one end of described annulus is little, and the closing structure of the other end ovalize has the wind groove of the finedraw of 1 mm wide at an oval-shaped end, and this structure constitutes whole annulus.
Beneficial effect
Huge finger ring of outer image of no leaf electric fan of the present utility model (desk fan) can produce strong cool air, also than traditional electric fan safety, and power saving (40W), environmental protection more.In addition, it cleans also and makes things convenient for manyly than the traditional electrical fan, and the user does not need to have worried for long-pending full dust on the cleaning flabellum.The same with the traditional electrical fan, it can an angle of 90 degrees swing.
Using the tangible benefit of this no flabellum fan is exactly that you do not worry that child's hand can be hurt by flabellum, and you also need not worry about to do to flabellum and have cleaned.
A lot of people are more interested to be that this fan does not exist fan center district " dead band ", and you also need not worry about the noise of flabellum cutting air generation in addition.

Fig. 2 is the side view of no leaf electric fan.
Fig. 3 is the air flows schematic representation of air at no leaf electric fan annulus.
Fig. 4 is the partial enlarged drawing of Fig. 3.
Embodiment
As shown in Figure 1, no leaf electric fan constitutes by going out wind apparatus 1 and main body.Go out wind apparatus 1 and be annulus, go out wind apparatus 1 and be toroidal.Main body constitutes pedestal 2, comprises brushless high-speed electric expreess locomotive 3, motor radiating hole 4, air passageways 5, anti-rubber 6, turbine 7, air intlet 8, the synchronous machine 9 of shaking altogether in the pedestal 2.
The annulus that goes out wind apparatus 1 is positioned at the top of pedestal 2.Can be connected as a single entity by welding manner and pedestal 2.In pedestal 2, brushless high-speed electric expreess locomotive 3 is installed in the top of pedestal 2, and the periphery of brushless high-speed electric expreess locomotive 3 has motor radiating hole 4, and air passageways 5 lower ends connect air intlet 8, and the upper end divides two ports to connect annulus, forms air passageways.Air passageways 5 is in the outside of brushless high-speed electric expreess locomotive 3 shells.The anti-rubber 6 that shakes is altogether arranged at the bottom of brushless high-speed electric expreess locomotive 3, and turbine 7 is installed in the bottom of brushless high-speed electric expreess locomotive 3, and the bottom of turbine 7 is provided with air intlet 8, is provided with synchronous machine 9 and motor driving plate and control circuit board at the bottommost of pedestal 2.
2 annulus that overhang air-out device 1 of pedestal, pedestal 2 holds brushless high-speed electric expreess locomotive 3, turbine 6, synchronous machine 8.Brushless high-speed electric expreess locomotive 3 drives turbine 7 rotations, and air is entered by air passageways 5 from air intlet 8, makes the trickle wind groove of air in the middle of annulus to blow out, and forms the wind that blows out.
Motor radiating hole 4 is used for the heat radiation of brushless high-speed electric expreess locomotive 3.When preventing that shaking rubber 6 altogether is used to prevent the rotation of brushless high-speed electric expreess locomotive 3, the vibrations of generation.
Synchronous machine 9 is used to not have the rotation of leaf electric fan itself.
Among the figure, arrow represents that air enters the flow direction that flows out with air.
As shown in Figure 2, top is the annulus side sectional view.The bottom is pedestal 2 side views.
As Fig. 3, shown in 4, cross section one end of annulus is little, and the closing structure of the other end ovalize has the wind groove of the finedraw of 1 mm wide at an oval-shaped end.This structure constitutes whole annulus.
Air enters from the annulus bottom, goes out from the wind concentrated flow, forms the wind that blows out forward.Because the structure of annulus, the wind that blows out forward can only folk prescription to blowing out forward.This function with the traditional electrical fan is consistent.Among the figure, arrow represents that air enters the direction that flows out with air.
In Fig. 3,4, air is exactly the position of finedraw wind groove from the position that the wind concentrated flow goes out.
