由于该种风扇用于产生通过喷嘴的高压气流的构件位于所述喷嘴所构成的闭合环路 外， 使其体积及所占用的空间位置较大， 影响其使用。 因此很有必要进行改进。
发明内容
本发明旨在提供一种改进的风扇装置以克服上述现有技术中的缺陷。本发明的目的是 要提供一种结构紧凑的无扇叶风扇装置。
为了达到上述目的， 本发明采用如下技术方案： 一种用于产生空气流的无扇叶风扇， 其特征在于， 所述风扇包括： 气流产生装置、喷嘴和连接管， 所述喷嘴包括内部通道和排 气口并具有闭合的环路，所述气流产生装置用于产生高压气流并且至少有部分位于所述喷 嘴的闭合环路内，所述连接管连接于所述气流产生装置与所述喷嘴之间，为所述高压气流 从所述气流产生装置至所述喷嘴提供流通的通道。
所述气流产生装置、所述喷嘴和所述连接管限定至少一个开口，所述风扇外部的空气 通过所述开口被从所述排气口喷射的高压气流所抽吸。
为了提高所述风扇的出风量，在所述连接管上可以设置排气口，在所述气流产生装置 上也可以设置排气口， 在所述连接管和所述气流产生装置上还可以同时设置排气口。
为了增强所述风扇外部的空气通过所述开口被从所述排气口喷射的高压气流所抽吸 的效果，所述喷嘴可以靠近所述排气口设置引导气流流过的柯恩达表面，所述连接管和所 述气流产生装置都可以靠近所述排气口设置引导气流流过的柯恩达表面。
柯恩达表面是指气流流过该表面能产生柯恩达效应的表面。柯恩达效应是说，流体会 紧贴在凸出物体的表面流动。
所述喷嘴所具有的闭合的环路， 可以是单个环路， 也可以是多个环路， 例如可以是两 个互相连通的同心的圆形环路； 所述喷嘴所构成的闭合的环路的形状， 可以是圆形， 可以 是椭圆形， 可以是圆角矩形， 可以是部分环形， 还可以是其它的形状。
所述气流产生装置可以采用多种形状，通常为圆柱型；所述气流产生装置至少有部分 位于所述喷嘴构成的闭合的环路内，所述气流产生装置通常全部位于所述喷嘴构成的闭合 的环路内； 所述气流产生装置通常位于所述喷嘴构成的闭合的环路的对称中心。
所述排气口可以采用多种形状， 可以是圆形， 可以是椭圆形， 可以是部分环形， 可以 是圆角矩形， 还可以是其它的形状； 所述排气口的出口通常采用缝隙状出口， 所述排气口 在其出口处的宽度通常在 0.2毫米至 8毫米之间， 优选地在 0.5毫米至 6毫米之间； 所述 排气口的出口方向与轴线方向的夹角通常小于 25度， 优选地小于 20度。
为了有利于提高所述排气口所喷射气流的速度，所述喷嘴在前部所述排气口处的横截 面尺寸通常小于其在后部的横截面尺寸。
关于所述排气口的出口与所述柯恩达表面之间的距离需要根据风扇所要达到的性能 来设计， 其距离通常在 1毫米至 30毫米之间。

所述风扇还可以是台扇， 可以是壁扇， 可以是吊扇， 可以是落地风扇， 还可以是其它 类型的风扇。
关于术语 "高压气流"是指气压高于所述风扇周围大气压的气流。
关于术语"无扇叶 "是用来描述气流从风扇组件中向前释放或喷出而不需要使用叶片 装置。通过该定义， 无扇叶的风扇可以被看作是具有没有叶片或翼的输出面或发射区， 气 流沿大致朝向使用者的方向从中释放或发射出去。
无扇叶风扇可以利用多种气流产生装置提供主要的空气来源来产生高压气流， 例如 泵、发电机、 电机或包含发动机转子和叶轮片等旋转设备的其他流体输送装置。 因此， 关 于术语 "无扇叶" 的说明的目的不在于延伸至动力源和零部件等风扇次要功能所需部件， 比如电机。 风扇次要功能的例子包括照明、 调节和风扇的摆动。
本发明具有如下积极效果：
本发明装置的气流产生装置位于喷嘴所构成的闭合环路内，其结构紧凑，占用空间小； 另外喷嘴所构成的闭合环路通常较大，可以容纳体积较大的气流产生装置，而体积较大的 气流产生装置容易提供噪声小、 气流量大的高压气流。

图 5示出了本发明的无扇叶风扇的第四个实施例。从图中可以看出， 本实施例与图 3 所示的实施例也相似， 只是所设置的排气口 4有所不同， 在本实施例中， 在每个连接管 3 上只设置了一排排气口， 而在图 3所示的每个连接管 3上设置了两排排气口。
图 6示出了本发明的无扇叶风扇的又一个实施例。从图中可以看出， 本实施例与图 3 所示的实施例也相似， 只是所设置的支架 5有所不同， 在本实施例中， 支架 5为一落地式 风扇的支架， 该支架与喷嘴 2固定连接。在另一个优选的实施例， 支架 5可以与气流产生 装置 1固定连接。
尽管已经展示和描述了目前认为是优选的本发明的实施例，但显而易见，本领域的技 术人员可以进行各种改变和改进， 而不背离由所附权利要求书所限定的本发明的范围。
