Abstract
The invention discloses a bladeless fan with a double-angle spray tube. The bladeless fan with the double-angle spray tube mainly comprises an annular air flow spray device 1, a base 2 and an air supercharging device 3. A first spray tube and a second spray tube are arranged on the inner side wall of the air flow spray device at intervals; an isolating block is arranged between the adjacent first spray tube and the second spray tube. As the air outlet area is reduced, the wind pressure is correspondingly increased on the condition that other functional parameters are consistent for blowing the wind further and entraining more air to an airflow channel; moreover, the air flow ejected from the first spray tube and the second spray tube form two rings of air flow with different directions, so that air quantity on the middle part of the airflow channel is prevented from being too little.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the two angle jet pipes of band mainly is comprised of annular airflow injection apparatus 1, pedestal 2 and air-flow supercharging device 3 without blade fan.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 flue 12 is annular hollow passages that are positioned at jet-impingement device 1 inside, are limited by outer side wall 13 and madial wall 14 docking.Air-flow supercharging device when work, the air in the external world is sucked from the inlet hole that is located on the base outer wall, through supercharging after-blow intake duct 12.
The interval arranges the first jet pipe 16 and the second jet pipe 17 on the madial wall 14 of jet-impingement device 1, is provided with spacing block 15 between the first adjacent jet pipe and the second jet pipe; Described the first jet pipe and the second jet pipe are arranged on madial wall in the form of a ring; Form the angle of 5-45 degree between the air-flow that the air-flow that the first jet pipe 16 blows out and the second jet pipe blow out.Air-flow in the air flue 12, from the first jet pipe and the ejection of the second jet pipe, inlet end at air-flow path forms the different air-flow of two circle spray angles, blow to that circle air-flow at air-flow path middle part, make the middle part of air-flow path inlet end form stronger negative pressuren zone, entrainment ambient air and enter the middle part of air-flow path, the throughput at air-flow path middle part is increased; Another circle air-flow flows to the outlet side along the surface of madial wall, utilizes Coanda effect to entrainment the air-flow path ambient air; Above-mentioned two circle air-flows merge the outlet side that flows to air-flow path.Usually, only be provided with circle spout and an angle without blade fan and fix, the throughput that causes the air-flow path middle part a little less than.Therefore the present invention, can overcome the weak defective of air-flow path middle part air-flow owing to form the air-flow that two circle injection directions have 5-45 degree angle, and the air-flow that blows to the user is more even.
Because the summation of the nozzle hole sectional area of the first jet pipe and the second jet pipe is less than the area of continuous annular jet, therefore, the air-flow air pressure of ejection is larger, can blow fartherly, the negative pressure that forms is also corresponding larger, also just can entrainment more air, thereby better dry effect.
Described the first jet pipe 16 tilts the outlet side of a part of air-flow along madial wall 14 wall flows to air-flow path from air flue 12 interior outlet sides to air-flow path.
The air-flow that described the first jet pipe 16 sprays is horizontal by the angle of 0-30 degree, the angle of air-flow horizontal by 15 to 60 degree of described the second jet pipe 17 ejections; The angle of described the second jet pipe and horizontal plane than the angle of the first jet pipe 16 and horizontal plane at the 5-45 degree.
The inwall of described the first jet pipe 16 and the second jet pipe 17 is curved, makes the air-flow in the air flue can flow to swimmingly air-flow path.
The projection of described the second jet pipe 17 on the plane that madial wall 14 launches forms 5 to 85 angles of spending with the air inlet end face of madial wall.The air-flow of the second jet pipe ejection does not directly blow to the outlet side of air-flow path, but side direction blows out, and forms the swirl shape air-flow in air-flow path.
The edge that is positioned at air flue 12 inside at described the first jet pipe 16 is provided with flow guide device, and steering flow flows into the first jet pipe swimmingly.
The edge that is positioned at air flue 12 inside at described the second jet pipe 17 is provided with flow guide device, and steering flow flows into the second jet pipe swimmingly.
In the power of air-flow supercharging device and performance all under the identical prerequisite, owing to leave the design of the independent jet pipe of spacing block in the middle of the present invention adopts, actual air-out area has been reduced, thereby blast is increased, and the distance of jet-impingement is also just farther, simultaneously, according to venturi principle, under stronger jet-impingement condition, the negative pressure of air-flow path inlet end is larger, can entrainment more air and enter air-flow path.
Because air has diffusivity, although leave distance between jet pipe, because air-flow has diffusivity, the user can not feel the space between the air-flow.
Above-described embodiment only is interpretation purposes of the present invention, and is not to be 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.
