香薰无叶风扇技术领域 本实用新型涉及一种风扇，属于通风设备技术领域。 Fragrances bladeless fan Technical Field  The present invention relates to a fan, ventilation FIELD belongs. 背景技术 传统的电风扇基本上包括基座、电机，叶片及具有格栅的风罩，电机位于基座上， 叶片为多个设置于电机的输出轴上，电机启动后带动叶片转动，从而产生空气流动，进而产生风，这种风扇既不安全，又费电，而且使用者需要为清理扇叶上积满的灰尘，清洗起来很费事，再则，叶片切割空气产生的噪音也比较大，而且风的波动也较大。  Traditional fan basically includes a base, a motor, a blade and a wind shield having a grid, a motor located on the base, a plurality of blades disposed on the output shaft of the motor, the motor starts driving the rotation of the blades to generate an air flow, thereby generating the wind, which is neither safe fan, and electric charges, and the user needs to clean the blades filled with dirt, cleaning up is very cumbersome, Furthermore, the cutting blade noise also generated by the air larger and larger wind fluctuations.  为此现有技术中公开了很多无叶风扇，该无叶风扇的基本结构包括基座、电机、 风轮及出风环，基座具有进风口，电机、风轮设于基座内腔，出风环设于基座上端并与，出风环具有出风缝隙，其工作原理是电机驱动风轮，进行强制增压，然后将空气输送到出风环，最后由出风环的缝隙中平稳地放出来，这种风扇没有叶片，所以安全、清洗方便，同时噪音小，风是平稳地送出来，所以波动也小。  To this end the prior art discloses a number of non-leaf fan, the bladeless fan basic structure comprising a base, a motor, an air ring and the rotor, the base having an air inlet, a motor, the rotor provided in the base lumen, the air ring provided at the upper end of the base and with an air ring having an air gap, its working principle is the motor driving the rotor, the forced pressurized air is then conveyed to an air ring, and finally out of the wind by the loop the gap is smoothly released, no such fan blades, so that safe, easy to clean, while the low noise, the wind is sent out smoothly, so the fluctuation is also small. 无叶风扇的公开文献可以参考专利号为ZL201020106004. 5的中国实用新型专利《无叶风扇》（授权公告号为CN201627736U)，还可以参考专利号为ZL201020133350. 2的中国实用新型专利《一种无叶风扇》（授权公告号为CN201650800U)等。 Bladeless fan publications can be referred to Patent No. ZL201020106004. 5 in Chinese utility model patent "bladeless fan" (authorized announcement No. CN201627736U), you can also refer to Patent Chinese utility model patent No. ZL201020133350. 2 of "a non- leaf fan "(notice of authorization number CN201650800U) and so on. 自古以来，香薰一直受到关注，它可净化空气，提高空气品质，塑造无污染的人类生存空间，也可促进新陈代谢，减少疲劳感，帮助维持呼吸道技能；还能调节生理机能，养颜美容，舒缓精神压力，促进精神旺盛，提高工作效率；最后还能使人心灵舒畅，心旷神怡，促进食欲，激发人体潜在免疫力。  Since ancient times, aromatherapy has been followed, it can purify the air, improve air quality, create pollution-free human living space, but also can promote metabolism, reduce fatigue, help maintain airway skills; also regulate physiological function, beauty beauty , relieve stress, promote the spirit of strong, improve work efficiency; and finally the mind can make people happy, relaxed and happy, promote appetite, stimulate the body potential immunity. 目前，有人已经开发了一种香薰和无叶风扇结合的新产品，见专利号为ZL201130011550. O的中国外观设计专利《香薰无叶风扇（心型）》（授权公告号为CN301655326S)，从该文献公开的图纸中可以看到该专利中将香薰装置设于基座一侧，这种设计存在如下不足：首先，由于香薰装置设于出风环底部的一侧，所以出风环不能有效地将香薰装置迅速散发开来，出风环送出的空气中香薰精油分布也极为不均匀，空气中精油混合的不充分，影响人体感受；其次，整个构造显得不够简洁、紧凑，摆放时需要占用较多的空间，影响整体的外观视觉。  Currently, someone has developed a new product for aromatherapy and a combination of non-leaf fan, see Patent No. ZL201130011550. O of Chinese design patent "Aromatherapy leaf fan (heart-shaped)" (notice of authorization number CN301655326S) from this document can be seen in the drawing disclosed in the patent Fragrances means provided on the base side, there is a disadvantage of this design: first, since the aroma device provided in the bottom side of the air ring, so that an air ring Fragrances will not effectively open the device to circulate through the air distribution of an air ring essential oil fed extremely uneven, essential oil blend in air is insufficient, affect human feelings; secondly, the entire structure was not very simple and compact, placed when the need to take up more space, affect the overall visual appearance. 实用新型内容 本实用新型所要解决的技术问题是针对上述的技术现状而提供一种出风环送出的空气中香薰精油分布极为均勻的香薰无叶风扇。 SUMMARY  The present invention is to solve the technical problem above for state of the art and to provide a ring of the wind to the air from a uniform distribution is extremely essential oils aroma bladeless fan.  本实用新型所要解决的又一个技术问题是提供一种结构布置紧凑的香薰无叶风扇。  to be solved by the present invention is a further technical problem is to provide a compact structural arrangement aroma bladeless fan.  本实用新型解决上述技术问题所采用的技术方案为：一种香薰无叶风扇，包括基座、风机机构、风道盖片及出风环，前述的基座具有内腔及与内腔连通的进风口，前述的风机机构和风道盖片自下而上依次设于基座的内腔，前述的出风环密封地设于基座的上端部并与基座的内腔连通，其特征在于所述基座的内腔位于风道盖片上方设有一精油催化装置，而所述出风环的下端盖住前述的精油催化装置。  The aspect of the present invention to solve the above technical problem is: one kind of aroma bladeless fan, comprising a base, blower means, air duct and the air ring cover sheet, the base having a lumen and the inner communicating the inlet chamber, the fan and duct means provided on the cover sheet in this order from the base of the lumen, out of the air ring provided at the upper end portion of the seal base and communicating with the lumen of the base, wherein said base duct lumen is located above the cover plate is provided with a catalyst device oil, and the lower end of the air ring covering the aforementioned essential oils catalytic device.  所述的风机机构可以包括电机、风轮及风机架，前述的风轮设于电机主轴上，前述的风机架轴向中空并具有一倒锥形的内腔，该风机架的下端口与基座的进风口相通，该风机架的外壁与基座的内壁密封配合，前述的电机连同风轮设于风机架的内腔，而前述的风轮则正对风机架的下端口。  The fan mechanism may include a motor, a wind turbine and wind rack, the wind wheel is provided on the motor shaft, the wind rack axial hollow and having an inverted conical lumen, the fan an air inlet port in communication with the base frame, an inner wall of the outer wall of the base chassis wind sealing engagement, the motor together with the rotor disposed in the lumen of the rack wind, the wind wheel and the positive wind under the rack port. 风机机构的优选设计利于空气在密封环境下迅速增压，产生强烈的气流，从而能有效地保证风输出功率。 Preferably the fan mechanism design facilitates rapid pressurized air in a sealed environment, a strong air flow, which can effectively ensure the output power of the wind.  所述的风道盖片装配于风机架的上端口，并且，所述风道盖片的上端面凸起呈锥形，周壁形成有供空气通过的进风通道，对应地，所述精油催化装置的底部呈与风道盖片适配的内凹锥形。 Duct  The cover sheet is attached to the air port of the rack, and the air channel cover plate projection tapered upper end, a peripheral wall formed with a passage for air intake through the air, correspondingly, the bottom oil catalytic device was adapted to a duct cover sheet concave taper. 这种设计能使风速保持稳定。 This design enables the wind speed remains stable.  所述的精油催化装置包括蕊头、电路板、用于设置蕊头的支座及精油瓶，该蕊头设于前述精油瓶的端口上，并具有伸入精油瓶内的棉芯或虹吸管，所述蕊头的一侧具有一竖直的安装面，所述的电路板竖直地设置于该安装面上，前述的精油瓶底部则呈与风道盖片适配的内凹锥形。  The catalytic device comprises a core of essential oil head, a circuit board for oil bottles and the carrier head core is provided, the head core is provided on the oil port of the bottle and having a wick extending into the bottle of essential oil or siphon, the head side of the core having a vertical mounting surface of the circuit board is vertically disposed on the mounting surface, the bottom of the concave shape of the bottle with oil duct cover sheet adapted cone.  将电路板侧面设置，解除了对精油散发的阻止，扩大了精油散发面，同时，电路板减少了与精油的直接接触，电路板不易腐蚀，甚至变黑，最后，因精油带来的突然降温和升温现象对电路板的损伤也大为降低，延长了电路板的使用寿命。  The side surface of the circuit board is provided, lifting the blocking of oil circulated, expansion of oil distributing surface, while the circuit board is reduced in direct contact with the oil, the circuit board does not corrode, and even black, and finally, by bringing oil the sudden cooling and warming phenomenon to damage the circuit board is also greatly reduced, extending the life of the board.  为使电路板设置更加稳定牢固，所述的支座的一侧具有一延伸座，所述电路板的底端则搁置于该延伸座上端面。  In order to more stably secure the circuit board is provided, one side of the abutment having a seat extending, bottom end of the circuit board is resting on the end surface extending base. 进一步，所述延伸座的上端面具有一条形槽，而所述电路板的底端则位于该条形槽内。 Further, the extension having an upper end face of the seat-shaped groove, and the bottom end of the circuit board is located in the bar slot.  进一步，所述的精油催化装置还包括一中空隔热架，该隔热架设于所述的支座内， 而所述的蕊头则设于该隔热架内。  Further, the essential oil catalytic device further comprising a hollow insulating holder, the insulating erected within the abutment, and said head core is disposed inside the insulating frame.  与现有技术相比，本实用新型的优点在于：基座中的电机带动风轮将空气吸入基座内部，气流加速后，经过风道盖片，将精油催化装置中精油带人出风环，经出风环的缝隙， 将混有精油的空气平稳地送出；整体结构紧凑，体积较小，同时，精油与空气混合充分而且均匀，给人舒适的感觉。  Compared with the prior art, the present invention is advantageous in that: the base of the motor to drive the rotor draws air into the inside of the base, to accelerate the gas flow through the duct cover sheet, an essential oil with a catalyst device oil al an air ring, slit by an air ring, oil will be mixed with air smoothly dispensed;
