具体实施方式 detailed description

[0024] 如图1、图2、图3、图4和图5所示,一种气流喷射装置2,安置在无叶风扇的基座上使用,所述的气流喷射装置2为中空的环形结构,中空部分为第一气流通道21,气流喷射装置2内部设有气道25,气流喷射装置2上设有环形的排气口23,所述的气道25与排气口23连通,在气流喷射装置2上设有环形的第二气流通道22 ;当主气流高速流过第二气流通道22的出风口时,会产生文氏管效应,把风扇侧面的气流通过第二气流通道22卷吸进入第一气流通道21内。 [0024] As shown in FIG 1, FIG 2, FIG 3, shown in a air-jet means 2 in FIG. 4 and 5, is disposed on the base used in the non-leaf fan, the air injection means 2 is a hollow annular structure, a first hollow portion of the gas flow passage 21, air-jet means 2 is provided with an internal air passage 25, air-jet means 2 is provided with an annular exhaust port 23, the airway 25 in communication with the exhaust port 23, in 2 is provided with an annular air jet means on the second gas flow passage 22; when the main gas stream flowing through the high speed second airflow passage outlet 22, it will produce a venturi effect, the air flow through the fan side of the second gas flow passage 22 entrainment 21 into the first gas flow passage.

[0025] 无叶风扇由基座I和气流喷射装置2组成,所述基座I的外壳上设有进气口11,基座I内部安置了电机12、由电机12带动旋转的叶轮13,空气通道14。 [0025] I bladeless fan by the base 2 and air injection means consisting, on the base of the housing is provided with I the intake port 11, disposed inside the base I of the motor 12, 12 is rotated by the motor driven impeller 13, air passage 14. 叶轮13是安置在基座I的外壳内,帮助吸入空气和给空气增压,然后把空气吹进气流喷射装置2。 The impeller 13 is disposed within housing base I help boost the intake air to the air and then blowing air into the air jet apparatus 2. 气流喷射装置2呈中空的环形结构,也可以是方形或椭圆形,如图6所示,只要轴线对称的即可。 Air jet apparatus has a hollow annular structure 2, may be square or oval, as shown in FIG. 6, to the long axis of symmetry.

[0026] 所述的第二气流通道22的进风口位于气流喷射装置2的外壁,出风口位于气流喷射装置2的内壁。 [0026] the second gas flow passage inlet 22 is located at the outer wall 2 of the air-jet means, the ejection outlet is located in the inner wall 2 of the air flow means. 使气流喷射装置2外壁外的空气,能够通过第二气流通道22,汇入第一气流通道21中。 Means that the air jet of the air outside the outer wall 2, through the second gas flow passage 22, the first gas flow passage 21 in import.

[0027] 所述的第二气流通道22通过分隔板24与气道25分隔,所述的分隔板24通过连接筋26与环形喷气口27连接。 [0027] the second gas flow passage 22 through the partition plate 24 and the airway of the partition 25, the partition plate 24 is connected to the annular rib 26 and the nozzle hole 27 through the connection.

[0028] 所述气道25是位于气流喷射装置2内部的气流通道,是由外壁28、分隔板24和内壁29顺序连接形成的。 [0028] 25 is located in the airway air jet apparatus 2 inside the air flow passage, by the outer wall 28, the partition plate 24 and the inner wall 29 formed by the connection order. 因此,在占用同等空间的情况下,本发明的气道25比其他无叶风扇的气道狭窄,所以气压更大,喷射力更强。 Thus, in the case of occupying the same space, the airway 25 of the present invention is narrower than the other airway bladeless fan, so that a greater pressure, the ejection force is stronger.

[0029] 所述外壁28的一端与分隔板24连接,另一端向内壁29的方向弯曲并包裹内壁29的末端。 One end of the partition plate [0029] 24 of the outer wall 28 and the other end is bent toward the inner wall 29 and inner wall 29 of the package end. 所述内壁29的一端与分隔板24连接,另一端向内弯曲,弯曲部分逐渐加厚末端呈水滴形,也就是说,外壁29的末端朝向气道25的一侧向外壁28的方向呈圆弧形弯曲,使气道25中的高压空气能够顺着内壁29的内侧弧线,顺畅地流出,经排气口23喷出。 One end of the inner wall 24 and the partition plate 29 and the other end is bent inwardly, the bent portion was gradually thickened end Pear, that is, toward the end of the outer wall 29 side was airway 25 in the direction of the outer wall 28 arcuate bend, the high-pressure air can be airway 25 along the inner wall of the inner arc 29 smoothly flows, discharged through the exhaust port 23.

[0030] 所述的内壁29的末端与外壁28的内侧留有间隙,形成与气道25连通的环形的排气口23。 [0030] the inner wall and the outer wall of the distal end 29 of the inner side of the clearance 28 is formed in communication with the airway 25 of annular exhaust port 23.

[0031 ] 所述气道25通过位于气流喷射装置2下方的通孔与基座I内的空气通道14联通。 An air passage in the through hole of the base I [0031] 25 through the airway device positioned beneath the air jet 14 2 Unicom.

[0032] 本发明吹向使用者的气流包括三个部分,第一部分是从环形喷气口23喷出的主气流;第二部分是主气流流动时,吸引风扇后方的气流进入第一气流通道21 ;第三部分是主气流高速流过第二气流通道22的出风口时,会产生文氏管效应,把风扇侧面的气流通过第二气流通道22卷吸进入第一气流通道21内,上述三股气流合并成一股更为强大的气流。 [0032] The present invention airflow blown toward the user comprises three portions, a first portion of the primary air flow is discharged from the annular nozzle hole 23; the second portion is the main air flow, a fan behind the suction air enters the first air flow passage 21 ; third part is a high-speed gas stream flows through the main air outlet of the second gas flow passage 22, it will produce a venturi effect, the air flow through the fan side of the second gas flow passage 22 into the suction roll 21 of the first gas flow passage, the above-described three-ply airflow combined into an even more powerful airflow.

[0033] 工作时,基座I内的电机12带动叶轮12旋转,将外部的空气从进气口吸入,经过加压后进入空气通道14,再通过设在气流喷射装置2下方的通孔进入气道25,最后从环形排气口23喷射而出。 [0033] In operation, the motor 12 drives the impeller to rotate within the susceptor 12 I, the outside air is sucked from the intake port, the pressurized air entering through the passage 14, and then through the through hole provided in the gas flow into the injection device 2 below airways 25, the exhaust port 23 and finally from the annular jet out. 由于内壁29朝向环形排气口23的一端向内弯曲,弯曲部分更加厚呈水滴形,使朝向气道的一侧线条流畅,这样,气道25内的气流就会顺畅地往环形排气口23流动,从环形排气口23喷出。 Since the inner wall 29 toward the exhaust end of the ring 23 is bent inwardly, the bent portion is more thick teardrop-shaped form, so that the side facing the airway smooth lines, so that the air flow within the airway 25 will be smoothly toward annular exhaust flow port 23, discharged from the annular discharge port 23. 由于内壁29向内弯曲,因此,在环形排气口23周围的内壁29的表面形成柯恩达表面,使排气口23喷出的气流改变流向,沿内壁29的表面吹向使用者,并卷吸位于气流喷射装置2后方的空气通过第一气流通道21吹向使用者,同时,由于第二气流通道22的出风口位于气流喷射装置2的内壁,当从环形排气口喷射出来的气流流过该位置时,根据文氏管效应,在第二气流通道22的出风口会产生低压区,吸引气流喷射装置2外壁外的空气流入第二气流通道22,再汇入第一气流通道21吹向使用者。 Since the inner wall 29 is bent inwardly, so that the annular surface of the exhaust port 23 is formed around the inner wall of the Coanda surface 29, the exhaust port 23 change the flow stream discharged, blown along the internal wall surfaces 29 of the user, and air entrained air jet is located behind the device 2 through the first gas flow passage 21 blows the user, while the inner wall 2 due to the second gas flow passage 22 located in outlet air-jet apparatus, when the air flow ejected from the annular exhaust port when the flow through position, based on the venturi effect, creates a low pressure region to the outlet passage 22 of the second part stream, the air outside the suction air-jet means 2 of the outer wall 22 into the second gas flow passage, a first gas flow passage 21 and then importing blown users.

[0034] 因此,本发明的无叶风扇,卷吸进入第一气流通道21的气流比申请号为200810177843.3的和申请号为200810177844.8的专利文件中公开的一种风扇大,因此,本发明的无叶风扇,在同等尺寸、功率下,能够产生更强大的气流,也就是风更大效果更佳。 [0034] Accordingly, the bladeless fan according to the present invention, a first gas flow entrained into the gas flow passage 21 than the Application No. 200810177843.3 and the large Application No. 200810177844.8 A fan in the patent documents disclosed, therefore, without the present invention leaf fan, in the same size, power, capable of producing more powerful airflow, which is a better wind greater effect.

[0035] 上述实施例仅是用来说明解释本发明的用途,而并非是对本发明的限制,本技术领域的普通技术人员,在本发明的实质范围内,做出各种变化或替代,也应属于本发明的保护范畴。 [0035] The above-described embodiments are merely for illustrative purposes to explain the present invention and are not restrictive of the invention, the present technical field of ordinary skill in the art, within the spirit of the present invention, various changes or substitutions, but also It shall fall within the protection scope of the invention.
