[0024] 请参阅图1,其为本实用新型第一实施例提供的无扇叶风扇100的立体示意图。 [0024] Referring to FIG. 1, a perspective schematic view of a first embodiment of the invention provides a bladeless fan 100 which is present. 无扇叶风扇100包括中空基座10、及安装在中空基座10上的出风头20。 Bladeless fan 100 comprises a hollow base 10, and the limelight 20 is mounted on a hollow base 10. 本实施例中,出风头20包括环状喷嘴210、中空的连接部220、及收容在连接部220内部的加热器230。 In this embodiment, the limelight 20 includes an annular nozzle 210, connected to a hollow portion 220, and housed inside the connector portion 220 of the heater 230. [0025] 请一并参阅图2,中空基座10具有收容空间110,外表面上设置有至少一个按钮101,底部具有进气口111,而顶部形成有外螺纹116。 [0025] Referring to FIG. 2, the hollow base 10 having a receiving space 110, is provided with at least one outer surface of the button 101, the bottom has an intake port 111 and the top 116 is formed with an external thread. 此外,中空基座10内还设置有控制电路板(图未示),而按钮101与控制电路板相连,从而用户可通过按钮101控制加热器230的工作状态。 Further, the hollow base 10 is also provided with a control circuit board (not shown), and the button 101 is connected to the control circuit board, so that the user can control the operation state of the heater 230 by the button 101. 例如控制加热器230是否开启以及加热功率等等。 For example, control of the heater 230 is turned on and the heating power and the like. 进气口111上方设置有喷气装置113,喷气装置113例如可包括马达以及叶片。 Intake port 111 is arranged above the jet means 113, the jet means 113 may comprise, for example, a motor and a vane. 喷气装置113可安装在固定在基座11内壁上的框架114上。 Jet means 113 may be mounted on the fixed frame 114 on the inner wall of the base 11. 喷气装置113工作时可从进气口111处吸取空气并对空气进行加速产生高速气流从连接部220及喷嘴210吹出。 May draw air from the air intake port 111 when the working device 113 and the air jet is accelerated to produce a high-speed air stream blown out from the connecting portion 220 and the nozzle 210. 喷气装置113吸气的速度可约为20-30升每秒(L/S),最好为27L/S。 Jet suction device 113 may be about 20 to 30 liters per second rate (L / S), preferably 27L / S. [0026] 喷嘴210大体呈环状,且其具有环状的内部通道211、以及与内部通道211相连通的喷口212及进气口213。 [0026] The nozzle 210 generally annular, and which has an internal annular passage 211, and communicates with the internal passage 211 of nozzle 212 and the intake port 213. 喷嘴210直径约为350毫米,然而喷嘴210还可具有其他的直径,例如300毫米。 Diameter of the nozzle 210 is about 350 mm, but the nozzle 210 may have other diameters, for example, 300 mm. 喷口212同样大体呈环状。 Also generally annular nozzle 212. 进气口213与中空连接部220的出气口222相连,因此当高速气流从出气口222吹出时即进入喷嘴210的内部通道211,并且最后从喷口212高速喷出。 Intake port 213 is connected with the hollow portion 222 is connected to outlet 220, so that when the high velocity air stream blown out from the outlet port 222 into the interior passage nozzle 210 i.e. 211, 212 and finally discharged from the high-speed jets. 喷嘴210的靠近喷口212处的外表面为柯恩达表面214。 The outer surface of the nozzle 210 near the discharge port 212 of the Coanda surface 214. 因此,当高速气流从喷口210喷出时,由于柯恩达表面214处的柯恩达效应,此高速气流得以放大。 Thus, when the high-speed air ejected from the nozzle 210, due to the Coanda effect of the Coanda surface 214, this high-speed flow is amplified. 在本实施例中,喷嘴210的总体配置为柯恩达表面214与喷嘴的中心轴的夹角约为15°。 Angle between the central axis in the present embodiment, the overall configuration of the nozzle 214 and the Coanda surface of the nozzle 210 is approximately 15 °. 此角度的选择的依据是让柯恩达表面214上的气流流动更加高效。 This angle is chosen so that air flow is based on the Coanda surface 214 is more efficient. 喷嘴210 在其中心轴的方向上具有一定厚度。 Nozzle 210 having a certain thickness in the direction of its central axis. 本实施例中喷嘴210在其中心轴的方向上至少延伸5厘米。 210 extends in the direction of the center axis of the nozzle at least 5 cm embodiment of the present embodiment. 喷嘴210剖面的总体轮廓大体呈翼形。 The overall profile of the nozzle 210 is substantially a wing cross section.

[0027] 具体地,上述柯恩达效应的放大作用以及产生的层状气流使得一股平稳的气流持续的吹向喷嘴210前的使用者。 [0027] Specifically, the amplifying action of the Coanda effect laminar and such that an air flow generated continuous smooth air blowing nozzle 210 before the user. 以上述吸气速率在20-30升每秒为例,在离喷嘴210 约三个喷嘴直径的距离处(约1000到1200毫米)的气体流量约为400到500L/S。 The intake rate at 20-30 liters per second in the example, the gas flow rate of about 210 from the nozzle diameter of the nozzle at a distance of three (approximately 1000 to 1200 mm) is about 400 to 500L / S. 气流的流速约为3到4米每秒。 Air flow rate of about 3-4 meters per second. 更高的流速可以通过减小柯恩达表面214与喷嘴210的中心轴的夹角得到。 Higher flow rates can be obtained by reducing the angle between the center axis of the Coanda surface 214 of the nozzle 210. 更小的角度使喷射出的气流方向集中,但其总流量有所降低。 Smaller angle direction of the air flow injected concentration, but the total flow reduced. 相反地, 更高的总流量可以通过增加柯恩达表面214与喷嘴210的中心轴的夹角获得,但此时,气流流速降低。 Conversely, a higher total flow 214 may be obtained by increasing the angle between the Coanda surface and the central axis of the nozzle 210, but this time, air flow rate was reduced. 因此无扇叶风扇100的性能可以通过柯恩达表面214与喷嘴210的中心轴的夹角来调节。 Thus performance bladeless fan 100 may be adjusted by the angle between the Coanda surface and the central axis 214 of nozzle 210.

[0028] 连接部220大体呈圆筒状,其内收容有加热器230。 [0028] The connection portion 220 substantially cylindrical shape, which is housed inside a heater 230. 由于连接部220位于喷嘴210的进气口213与喷气装置113之间,因此加热器230也就位于进气口213与喷气装置113之间。 Since the connecting portion 220 positioned between the nozzle 113 and the inlet port 213 of the jet means 210, and therefore also the heater 230 is located in the air inlet means 213 and 113 between the jets. 加热器230例如可用螺丝固定于连接部220内壁。 The heater 230 can be used, for example, screws to the inner wall portion 220 is connected. 此外,加热器230与连接部220之间还可设置成可拆式连接,例如采用卡钩进行卡合。 Further, the heater 230 may also be provided to the connecting portion 220 detachably connected, for example, using hook engagement. 连接部220的底部形成有外螺纹221。 A bottom connector portion 220 is formed with an external thread 221. 连接部220的内螺纹221与基座10的内螺纹116相互匹配,因此,连接部220可以螺纹配合的方式可拆卸地连接于基座10上。 Internal threads 116 internally threaded portion 221 connected to the base 10, 220 match each other, therefore, the connection portion 220 may be screwed manner detachably connected to the base 10. 然而,可以理解,除采用本实施例的螺纹配合的方式外,还可采用其他可拆卸连接方式,例如可在连接部220的底部形成凸榫,而在基座110顶部形成榫眼,从而连接部220与基座110之间可用榫接的方式接合。 However, it will be appreciated that, in addition to using the threaded fitting of the present embodiment mode, it can also use other detachable connections, for example, may be formed at the bottom of the connector tongue portion 220 is formed at the top of the base mortise 110 so that the connection available mortise way of engagement between the portion 220 and the base 110. 由于设置有加热器230,因此连接部220需采用耐高温的材料例如(聚苯醚醚酮(聚二醚酮)或聚四氟乙烯等)制成。 Since the heater 230, so that the connection portion 220 is made for an example (phenylene ether ether ketone (polyglycol ether ketone), or polytetrafluoroethylene) using a material resistant to high temperatures.
