Description
Technical field
The present invention relates to a kind of bladeless fan, belong to the optimisation technique of fan.
Background technology
Existing fan is rotated by driven by motor blade, accelerates then to blow to user by air pressurized by blade, excellent
Point is the sensation bringing blowing to user, but there are following 4 deficiencies: one is that the blade velocity rotated is the highest, and imprudence is touched
Attend the meeting and damage, although most fan uses outer housing to surround blade to reduce danger;Two are blade and outer housing is difficult to
Clean;Three is also to produce noise in blade rotary course, brings interference to user;Four is owing to air-flow is through blade surface
Time change, the wind produced by boasting is uneven, and user may feel that a burst of high wind as similar pulse.
The patent document with Application No. 200810177844.8 of Application No. 200810177843.3 discloses
A kind of fan, is made up of pedestal and the annular vent mouth being arranged on pedestal, is provided with and receives in pedestal in annular vent mouth
The inner passage of air-flow and air vent, the air-flow that the air outside fan is ejected by air vent aspirates, and makes to blow to use
The air-flow of person increases.The advantage of this design is not have exposed blade, solves blade and is difficult to clean and with potential safety hazard
Deficiency, and reduce noise, there is stronger visual impact, the uniform air-flow of speed ejected by air vent, very
Utilize well Coanda effect to change the flow direction of air vent air-out, and drive the air outside fan to flow to user, order
User experiences relatively stable airflow effects.Owing to suction fan is arranged in pedestal, air inlet is arranged in base wall,
Blower fan air is sucked pressurization and feeding is positioned at the annular vent mouth above pedestal, causes the lift supplied gas long, to air
The requirement of supercharging is the highest, thus higher to the rotation speed requirements of blower fan, further, since air entry concentrated setting is in base wall,
Air velocity is relatively big, and the noise causing gas current friction to produce is the biggest.
It is, thus, sought for a kind of induction noise is little, lift of supplying gas is short, the bladeless fan that power is relatively low.
Summary of the invention
It is an object of the invention to: providing a kind of induction noise little, lift of supplying gas is short, the bladeless fan that power is relatively low.
The technical scheme is that a kind of bladeless fan, mainly by the gas of pedestal 1 with the annular being positioned at above pedestal 1

Put;In the drive 51 of described power set 5 enters airflow injection device and it is connected with air-flow pressurizer;Described transmission
Take turns 51 band moving air flow pressurizer work;Impeller 3 is selected in described air-flow pressurizer, and described impeller 3 is by transmission ring 31 He
Blade 32 forms;Hollow wall in airflow injection device 2 is provided with more than 2 location bearings 4, and drive 51 enters jet-impingement
The part of device and location bearing 4 are in airflow injection device 2 inwall symmetric arrays;The transmission ring 31 of impeller 3 is provided with and transmission
The driving groove that ring is coaxial;It is provided with tooth on the surface of described driving groove, drive 51 and location bearing 4;These teeth are parallel to each other,
In running engaged.
Airflow injection device 2 is provided with air inlet 21 and ring jet mouth 22.
Described air inlet is positioned at the inlet end of airflow injection device.
Described air inlet is arranged around the inlet end end face of airflow injection device.
Inlet end edge along airflow injection device arranges a circle protection drainage screen, and described protection drainage screen covers
QI KOU.
Described puff prot is positioned at inside the outlet side of airflow injection device.
Beneficial effect:
1, inside airflow injection device, be provided with impeller, air inlet and puff prot be set at its wall, shorten air inlet and
Distance between giving vent to anger, it is possible to reduce energy consumption, and noise is less.

Fig. 1 is the main TV structure schematic diagram of the present invention;
Fig. 2 is the left view sectional view of the present invention;
Fig. 3 is the partial enlarged drawing of Fig. 2;
Fig. 4 be the present invention the axonometric chart of impeller.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of bladeless fan, mainly by pedestal 1 be positioned at the annular above pedestal 1
Airflow injection device 2 forms, and is provided with power set 5 in pedestal, is provided with air inlet 21 and ring jet in airflow injection device 2
Mouth 22;Hollow positioned inside air-flow pressurizer in airflow injection device 2;The drive 51 of described power set 5 enters
In airflow injection device and it is connected with air-flow pressurizer;Described drive 51 band moving air flow pressurizer work.
The bladeless fan of the present invention is placed in power set in pedestal, but the drive 51 of power set 5 enters air-flow
In injection apparatus and it is connected with air-flow pressurizer.Air inlet is arranged on airflow injection device wall, is the most also annular.
Arranging concrete, air inlet both can be the annular of circling gas flow injection apparatus one circle, it is also possible to be provided with connection by centre
Multiple air inlets composition that the circling gas flow injection apparatus of muscle is arranged.Air inlet and puff prot are all the axles with airflow injection device
The heart is the loop configuration of axle.
Impeller 3 is selected in described air-flow pressurizer, and described impeller 3 is made up of transmission ring 31 and blade 32.At air-flow
The hollow wall of injection apparatus 2 be provided with more than 2 location bearings 4, location bearing mainly play to impeller support, spacing, with
And reduce friction of motion resistance and the effect of noise.
Drive 51 enters the part of airflow injection device with location bearing 4 in airflow injection device 2 inwall symmetric arrays.
The transmission ring 31 of impeller 3 is provided with the driving groove coaxial with transmission ring.Driving groove enters the portion of airflow injection device with drive
Divide and the surface formation of location bearing closely cooperates, make impeller 3 be limited between drive and location bearing, make impeller be limited
It is scheduled on the hollow space of airflow injection device, will not collide with the inwall of airflow injection device, and can smooth movements.
Drive impeller rotates, air is internal from air inlet suction airflow injection apparatus 2, from spray after pressurization
QI KOU sprays, and utilizes the Coanda surface of puff prot, the Air Entrainment around airflow injection device 2 is come, thus drives week
The more Air blowing in limit.
The surface of transmission ring 31, drive 51 and location bearing 4 is provided with tooth or rubbing surface.These teeth are parallel to each other, in fortune
During row engaged.
Described air inlet is arranged around the end face of the inlet end of airflow injection device.
Inlet end edge along airflow injection device arranges a circle protection drainage screen, and described protection drainage screen covers
QI KOU, to prevent from accidentally finger or foreign body being entered air inlet.
Described puff prot is positioned at the inner side of airflow injection device and near outlet side, between puff prot and outlet side
The wall of airflow injection device be set to arc, air is when puff prot gushes out, according to coanda principle, it is possible to by surrounding
Air Entrainment comes to blow out, and the air-flow making blowout is bigger.
Owing to air-flow pressurizer is directly positioned in airflow injection device, air inlet and puff prot are both mounted at air-flow spray
On injection device, the distance of air inlet and puff prot significantly reduces, and the area of air inlet is bigger, therefore, and the nothing of the present invention
Blade fan is under comparable size, power, it is possible to producing more powerful air-flow than other bladeless fans, namely the bigger effect of wind is more
Good, and noise is less.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The those of ordinary skill in field, in the essential scope of the present invention, makes a variety of changes or substitutes, also should belong to the guarantor of the present invention
Protect category.
