Abstract
The invention discloses a bladeless fan provided with independent spray holes. The bladeless fan mainly comprises an annular air current jetting device, a base and an air current boosting device. A plurality of independent spray holes are formed in the inner side wall of the air current jetting device. The air outlet area is reduced, thereby correspondingly increasing the air pressure on the premise that other functional parameters are consistent, increasing the blowing distance and winding more air into an air current channel.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, with independent spray orifice without blade fan, mainly formed by annular airflow injection apparatus 1, pedestal 2 and air-flow supercharging device 3; Jet-impingement device 1 is positioned at pedestal 2 tops, and its middle part limits an air-flow path; Jet-impingement device comprises gas collection storehouse 11, air flue 12, outer side wall 13, madial wall 14; Gas collection storehouse 11 is positioned at bottom, is communicated with the air outlet of the air-flow supercharging device 3 that is positioned at pedestal 2; Pedestal 2 outer walls are provided with inlet hole, and air is sucked in pedestal 2 from inlet hole by air-flow supercharging device 3, pressurization after-blow intake duct 12.Air flue 12 is annular hollow passages that are positioned at jet-impingement device 1 inside, is docked and is limited by outer side wall 13 and madial wall 14.
Air in air flue 12 sprays from the multiple independently spray orifices 15 that are located at the madial wall 14 of jet-impingement device 1.These separate spray orifices 15 are provided in a side of the through hole on madial wall, and one end is communicated with air flue 12, and the other end is communicated with air-flow path; Described spray orifice 15 surroundings along air-flow path arrange in the form of a ring.
In the power of air-flow supercharging device and performance all under identical prerequisite, because the present invention adopts the middle design of staying gapped independent spray orifice, the exhaust outlet gross area is reduced, the pressure of spray orifice air outlet improves, the negative pressure of air-flow path inlet end is increased, thereby entrainment more air.Under equal-wattage, air output is larger, and lift is farther; Or in the situation that keeping air output identical, can reduce power.From the identical distance of fan, adopt the present invention, the blast that user experiences and air quantity are all larger.
Because air has diffusivity, although leave distance between spray orifice, air-flow has spread towards periphery in the mobile process of user, and user can not feel space between air-flow.
Because air-flow will blow to outlet air end from air intake, therefore, described spray orifice 15 tilts from the interior outlet side to air-flow path of air flue 12.
The vertical cross-section of described spray orifice 15 and the air inlet end face of air-flow path forms the angle of 30 to 70 degree, and its effect is that guiding air-flow blows toward outlet side.The air flow direction outlet side of spray orifice ejection, swiftly flowing air-flow makes inlet end form low pressure area, enters in air-flow path thereby entrainment air-flow path ambient air, jointly flows to the direction of outlet side with air-flow.
The inwall of described spray orifice 15 is curved, makes the air-flow in air flue can flow to swimmingly outlet side, and utilizes Coanda effect to entrainment air.
Projection in the plane that described spray orifice 15 launches at madial wall 14 and the air inlet end face of madial wall form the angle of 5 to 85 degree, make oblique the blowing out of air-flow of spray orifice ejection, form swirl shape air-flow in air-flow path.
The edge that is positioned at air flue 12 inside at described spray orifice 15 is provided with flow guide device, and guiding air-flow enters spray orifice.
The spray orifice group of more than one circular array is set as required, on described madial wall 14.
The jet nozzle angle difference of described multiple spray orifice groups, just can entrainment air-flow path ambient air from multiple angles, and the air that makes to flow to user is more.
When work, be located at air-flow supercharging device 3 in the pedestal 2 inlet hole air amount from pedestal 1 outer wall, after supercharging, send in the gas collection storehouse 11 being communicated with it, enter again in air flue 12, under the guiding of flow guide device, enter spray orifice ejection, inlet end at air-flow path forms negative pressure, jet-impingement device 1 ambient air is entrainmented, thereby drive the more air of periphery to blow to user.
Be mainly to utilize the annular flow of ring-type spout ejection to form negative pressure at air-flow path without the working principle of blade fan, under the effect of negative pressure, entrainment ambient air, air-flow is increased.By independently spray orifice is set, although make the air-flow of ring-type spout produce interruption, because the distance between spray orifice is less, and air-flow has diffusivity, therefore, still can form ring-type from the air-flow of spray orifice ejection.But, compared with the continuous annular spout of other designs, owing to adopting the design of independent spray orifice, reduce exhaust outlet area, the stream pressure of spray orifice ejection has been increased, therefore, just make the negative pressure of generation in air-flow path larger, thereby can entrainment more air.Therefore, under equal-wattage, air output is larger, and lift is farther; Or in the situation that keeping air output identical, can reduce power.
Above-described embodiment is only for interpretation purposes of the present invention, and is not limitation of the present invention, and those skilled in the art, in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
