具体实施方式 Detailed ways

[0021] 为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效,以下结合附图及较佳实施例,对依据本发明提出的无叶片风扇其具体实施方式、结构、特征及其功效,详细说明如后。 [0021] To further elaborate the technical means and effects the present invention is predetermined to achieve the object of the invention taken in conjunction with the following drawings and preferred embodiments of the bladeless fan according to the present invention is set forth specific embodiments, structure, characteristics, and their effectiveness, as will be described in detail.

[0022] 请参见图1,本发明实施例之一的无叶片风扇100包括进气单元10与出风结构20。 [0022] Referring to FIG 1, one embodiment bladeless fan 100 of the present invention includes an intake unit 10 and the air outlet structure 20. 进气单元10与出风结构20相连。 10 and the air intake unit 20 is connected to the air outlet structure. 出风结构20包括气体通道22与环形壳体对。 20 comprises a gas inlet structure 22 and the annular housing channel pair. 环形壳体M环绕气体通道22。 M annular housing 22 surrounds the gas passage. 请参见图2,环形壳体M具有第一端面M2、第二端面M4、气体出口246与添加物出口M8。 Referring to Figure 2, the annular housing having a first end surface M M2, M4 second end, the gas outlet 246 and an additive outlet M8. 其中,第一端面242与第二端面244相对,气体出口246与添加物出口248形成于环形壳体M的内壁上并与气体通道22相连通。 Wherein the first end surface 242 and a second end 244 opposite the gas outlet and the additive outlet 246 is formed on the inner wall of the annular housing 248 and M 22 communicates with the gas passage. 气体出口246靠近第一端面M2。 A gas outlet 246 near the first end surface M2.

[0023] 承上述,环形壳体M形状为圆环形。 [0023] Bearing the above, M annular housing a circular ring shape. 可以理解,根据设计或使用需求的不同,环形壳体M也可设计为圆环形外的其他形状。 It will be appreciated, depending on the design or requirements, M annular housing may be designed in other shapes of an outer annular.

[0024] 气体出口246可与进气单元10相连通,例如是通过出风结构20内的内部通道(图未标)连通于进气单元10。 [0024] The gas outlet 246 may be connected through an intake unit 10, for example, by the structure 20 inside the wind passage (not labeled) to the intake unit 10 communicates. 并且,为达成柯恩达效应,在气体出口246的侧壁上可设置柯恩达表面M7。 Further, to achieve the Coanda effect, on the sidewall of the gas outlet 246 may be provided Coanda surface M7. 进气单元10从外界抽吸空气101,之后抽吸的空气101可从气体出口246被排出。 An intake unit 10 sucks air from the outside 101, 101 after the suction air can be discharged from the gas outlet 246. 由于气体出口246的侧壁上设置有柯恩达表面M7,因此从气体出口246排出的空气101会产生柯恩达效应,带动/卷吸气体出口246附近的空气101,使得从气体通道22吹出空气气流的放大。 Since there is provided on the sidewall of the Coanda surface M7 gas outlet 246, it will produce the Coanda effect the air 101 discharged from the gas outlet 246, drive / air entrainment gas 101 near the outlet 246 so that the gas passage 22 from the amplifying blowing air flow. 可以理解,柯恩达效应可在不同的表面产生,或可结合使用环形壳体M 的内部或外部设计以取得所需的空气流动和卷吸效果。 It will be appreciated, the Coanda effect may be produced in different surface, or may be used in conjunction with M annular housing interior or exterior design to achieve the desired air flow and entrainment effect.

[0025] 添加物出口248用以流出添加物102。 [0025] 248 to an additive outlet 102 flows additives. 添加物102可为水、香精或除虫剂等物质。 Additive 102 can be water, fragrance or pest control materials or the like. 具体在本实施例中,添加物出口248可靠近环形壳体M的第二端面M4,并面向第二端面M4,从而可使得流出的添加物102位于无叶片风扇100吹出的空气流的外围,进而避免添加物直接吹向使用者正面。 In this particular embodiment, the additive outlet 248 may be close to the second end face of the annular housing M M4, M4 and facing the second end face, such that the additive flows 102 may be located at the periphery of the air flow blown bladeless fan 100, thereby avoiding additives directly blown onto the front of the user. 并且添加物出口248与气体出口246还可在环形壳体M的壳壁内相连通。 Additive outlet 248 and gas outlet 246 may also be communicated in the housing wall of the annular housing M. 这样,部分被进气单元10抽吸进入的空气101在向外排出时,会经过添加物出口248与添加物102相混合,从而可增加添加物102与空气流的边缘部分的混合均勻性。 Thus, the portion 10 is drawn into the air intake unit 101 is discharged outwardly through the additive outlet 248 will be mixed with the additive 102, thereby increasing the uniformity of mixing with additive 102 of the edge portion of the air flow. 可以理解,在本发明的其他实施例中,添加物出口248也可设置在环形壳体M的内壁上靠近气体出口246的位置。 It will be appreciated that in other embodiments of the present invention, the additive outlet 248 may also be provided a position close to the gas outlet 246 on the inner wall of the annular housing M. 此外,用于承载添加物102的添加物储槽,可以与环形壳体M — 体成型或是外接。 Further, an additive for carrying additive reservoir 102, the annular housing may be M - or external shaping.

[0026] 使用时,由于无叶片风扇100设有添加物出口M8,因此可使添加物102从添加物出口248中流出,从而增加无叶片风扇100的附加使用功能。 [0026] In use, since the bladeless fan 100 is provided with an additive outlet M8, additives 102 can thus flow out of the additive outlet 248, thereby increasing the use of the additional features bladeless fan 100. 详细来说,例如可使水气从添加物出口248流出,从而增加空气中的湿度,避免使用者皮肤干燥,产生不适;或者,可使香料气体从添加物出口248流出,从而使空气流中含有香味;再或者,可使杀虫剂的气体从添加物出口248流出,从而消灭空气流中的细菌或其他有害动物。 Specifically, for example, that the water from the additive gas flows out the outlet 248, thereby increasing the humidity in the air, to prevent users from dry skin, uncomfortable; air stream Alternatively, the gas flows from the flavor additive outlet 248, so that the containing a flavor; Still alternatively, the gas can flow from the pesticide additive outlet 248, thereby eliminating air flow bacteria or other harmful animals. 此外,由于无叶片风扇100 设有添加物出口对8,可使添加物分散于空气流中,因此还可节省其他家庭电器,例如空气加湿器等的使用。 Further, since the bladeless fan 100 to outlet 8 provided with additives, the additives can dispersed in an air flow, and therefore can save other household appliances, for example, an air humidifier or the like.

[0027] 请参见图3,所示为本发明另一实施例的无叶片风扇200。 [0027] Referring to FIG 3, another embodiment of the bladeless fan 200 of the present invention shown in FIG. 无叶片风扇200与无叶片风扇100相似,其不同点在于:无叶片风扇200包括添加物储槽50与导流单元52。 200 similar bladeless fan bladeless fan 100, which is different in that: bladeless fan 200 comprises an additive reservoir 50 and the guide units 52. 添加物储槽50可拆卸地安装于环形壳体44内,而导流单元52则是连通于添加物储槽50与添加物出口448之间。 Additive reservoir 50 is removably mounted within the annular housing 44, the guide unit 52 is a communication between the reservoir 448 to the additive outlet 50 and the additive. 其中,添加物储槽50可储存有水、香精或除虫剂等添加物。 Wherein the additive reservoir 50 can store water, flavor additives, or the like insecticides. 特别地,在本实施例中,为便于使添加物转变成气体,无叶片风扇200还可包括加热元件M。 In particular, in the present embodiment, for convenience that the additive into the gas, bladeless fan 200 may further include a heating element M. 加热元件M例如与导流单元52相连接。 M, for example, a heating element is connected to the guide unit 52. 可以理解,在本发明的其他实施例中,加热元件M也可与添加物储槽50相连接;或者省略加热元件54,而令导流单元52中包括毛细管结构,以直接将添加物储槽50导入到添加物出口448再扩散出去。 It will be appreciated that in other embodiments of the present invention, the heating element 50 may also M additive reservoir is connected to; or omit the heating element 54, so that the capillary flow unit 52 includes a structure to direct the additive reservoir 50 exit 448 and then imported to supplement spread out.

[0028] 此外,可以理解,在本发明的其他实施例中,添加物储槽还可直接与环形壳体的内部通道相连通,让气体出口可与添加物出口结合为一体,以节省添加物出口的设置;而此时无叶片风扇的其他结构可与上述实施例中相应的结构相同或相似,此处不再赘述。 [0028] Further, it is understood that in other embodiments of the present invention, the additive reservoir may also be directly connected to the internal passage through the annular housing, so that the gas outlet may be combined into one outlet with an additive, the additive in order to save an outlet is provided; but before the other blades of the fan structure without the above-described embodiments may be respective the same or similar structure, not further described herein.

[0029] 综上所述,本发明实施例的无叶片风扇中,由于设有添加物出口,因此可使添加物从添加物出口中流出,从而增加无叶片风扇的附加使用功能,以方面使用。 [0029] In summary, the bladeless fan in an embodiment of the present invention, since the outlet of the additive, the additive can thus flow from the outlet of the additive, thereby increasing the use of the additional features bladeless fan, to the use of .

[0030] 以上所述,仅是本发明的较佳实施例而已,并非对本发明作任何形式上的限制,虽然本发明已以较佳实施例揭露如上,然而并非用以限定本发明,任何熟悉本专业的技术人员,在不脱离本发明技术方案范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本发明技术方案内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本发明技术方案的范围内。 [0030] The above are only preferred embodiments of the present invention only, not limitation of the present invention in any form, although the invention has been disclosed above by the preferred embodiments, but not intended to limit the present invention, anyone familiar with Those skilled in the art, without departing from the scope of the technical solution of the present invention, when the content of the above techniques can be used to make minor modifications disclosed as equivalent variations or modifications equivalent embodiments, but all without departing from the technical content of the present invention, according to technical essence of the invention is a simple modification of any of the above embodiments made equivalent modifications and variations, provided they fall within the scope of the present invention.
