Embodiment
As Fig. 1, Fig. 2 and shown in 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; The 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 the 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 limited by outer side wall 13 and madial wall 14 docking.
Air in air flue 12 sprays from a plurality of independently spray orifices 15 on the madial wall 14 that is located at jet-impingement device 1.These separate spray orifices 15 are provided in a side of the through hole on madial wall, and an end is communicated with air flue 12, and the other end is communicated with air-flow path; Described spray orifice 15 is arranged around air-flow path in the form of a ring.
In the power of air-flow supercharging device and performance all under identical prerequisite, stay the design of gapped independent spray orifice due to the utility model in the middle of adopting, make the exhaust outlet gross area reduce, the pressure of spray orifice air outlet improves, make the negative pressure of air-flow path inlet end increase, thereby entrainment more air.Under equal-wattage, air output is larger, and lift is farther; Or in the situation that the maintenance air output is identical, can reduce power.From the identical distance of fan, adopt the utility model, the blast that the user experiences and air quantity are all larger.
Because air has diffusivity, although leave distance between spray orifice, to have spread towards periphery in the process that air-flow flows to the user, the user can not feel the space between air-flow.
Because air-flow will blow to outlet air end from air intake, therefore, described spray orifice 15 is from the interior outlet side inclination to air-flow path of air flue 12.
Described spray orifice 15 forms 30 to 70 angles of spending with the vertical cross-section of the air inlet end face of air-flow path, and its effect is that steering flow blows toward the outlet side.The air flow direction outlet side of spray orifice ejection, swiftly flowing air-flow make inlet end form low pressure area, enter in air-flow path thereby entrainment the air-flow path ambient air, jointly flow 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 the outlet side, and utilizes Coanda effect to entrainment air.
The projection of described spray orifice 15 on the plane that madial wall 14 launches and the air inlet end face of madial wall form the angles of 5 to 85 degree, make oblique the blowing out of air-flow of spray orifice ejection, formation 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 steering flow enters spray orifice.
The spray orifice group of an above circular array is set on described madial wall 14 as required.
The jet nozzle angle of described a plurality of spray orifice groups is different, just can entrainment the air-flow path ambient air from a plurality of angles, makes the air that flows to the user more.
During work, be located at the interior air-flow supercharging device 3 of pedestal 2 from the inlet hole air amount of pedestal 1 outer wall, send into after supercharging with it in the gas collection storehouse 11 that is communicated with, enter again in air flue 12, enter the spray orifice ejection under the guiding of flow guide device, inlet end at air-flow path forms negative pressure, and jet-impingement device 1 ambient air is entrainmented, and blows to the user thereby drive the more air of periphery.
Working principle without blade fan is mainly to utilize the annular flow of ring-type spout ejection to form negative pressure at air-flow path, entrainments ambient air under the effect of negative pressure, and 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, compare with the continuous annular spout of other designs, due to the design of adopting independent spray orifice, reduced the exhaust outlet area, the stream pressure of spray orifice ejection has been increased, therefore, just make the negative pressure that produces 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 the maintenance air output is identical, can reduce power.
Above-described embodiment is only interpretation purposes of the present utility model; and be not to be to restriction of the present utility model, those skilled in the art are in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
