Description
Technical field
The present invention relates to a kind of fan, especially relate to a kind of on-bladed fan.
Background technique
Fan usually can be used in daily life as household electric appliance.Traditional fan comprises drive unit and blade, and drive unit has rotatingshaft, and blade then is installed on the rotatingshaft and is driven rotation and made air flows by drive unit.
Yet, in traditional fan, inhomogeneous and be easy to generate noise by the air stream that rotor blade produced.
Occurred a kind of on-bladed fan in the recent period, it can improve the uniformity of air stream and reduce noise.The on-bladed fan generally comprises air inlet unit and air-out structure, is provided with coanda (Coanda) surface in the air-out structure.During use, air inlet unit suction ambient air, discharge from the gas outlet of air-out structure the boosted back of the ambient air that is drawn into.When air is surperficial by coanda,, the amount of moving air is amplified because Coanda effect (Coanda Effect) also can drive the gas outlet ambient air and flow.
Although compared to traditional fan, the on-bladed fan has more advantage, and existing on-bladed fan additional function is less, can not provide more convenience to the user.For example, use the on-bladed fan to make user's dry skin easily for a long time, produce uncomfortable in some arid regions.
Summary of the invention
In view of this, be necessary to provide a kind of on-bladed fan with more additional functions.
A kind of on-bladed fan, it comprises air inlet unit and the air-out structure that links to each other with the air inlet unit.The air-out structure comprises that gas channel reaches the toroidal shell around gas channel.Toroidal shell has first end face and and the first end face second opposed end face.Be formed with the gas outlet and the affix outlet that communicate with gas channel on the inwall of toroidal shell, gas outlet is near first end face.
In the above-mentioned on-bladed fan, owing to be provided with the affix outlet, affix is flowed out from the affix outlet, thereby increase the additional function of use of on-bladed fan, use with the aspect.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, and for above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, below especially exemplified by preferred embodiment, and conjunction with figs., be described in detail as follows.

Embodiment
Reach technological means and the effect that predetermined goal of the invention is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of on-bladed fan, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
See also Fig. 1, the on-bladed fan 100 of one of embodiment of the invention comprises air inlet unit 10 and air-out structure 20.Air inlet unit 10 links to each other with air-out structure 20.Air-out structure 20 comprises gas channel 22 and toroidal shell 24.Toroidal shell 24 is around gas channel 22.See also Fig. 2, toroidal shell 24 has first end face 242, second end face 244, gas outlet 246 and affix outlet 248.Wherein, first end face 242 is relative with second end face 244, and gas outlet 246 and affix outlet 248 is formed on the inwall of toroidal shell 24 and with gas channel 22 and is connected.Gas outlet 246 is near first end face 242.
Hold above-mentionedly, toroidal shell 24 is shaped as ring.Be appreciated that the difference according to design or user demand, toroidal shell 24 also can be designed to other outer shapes of ring.
During use,, affix 102 is flowed out from affix outlet 248, thereby increase the additional function of use of on-bladed fan 100 because on-bladed fan 100 is provided with affix outlet 248.Specifically, aqueous vapor is flowed out from affix outlet 248, thereby increase airborne humidity, avoid user's dry skin, produce uncomfortable; Perhaps, spices gas is flowed out from affix outlet 248, thus make contain in the air stream savory; Again or, the gas that can make pesticide flows out from affix outlet 248, thereby eliminates bacterium or other harmful animals in the air stream.In addition,, affix is scattered in the air stream, therefore also can saves other household appliances, for example the use of air humidifier etc. because on-bladed fan 100 is provided with affix outlet 248.
See also Fig. 3, be depicted as the on-bladed fan 200 of another embodiment of the present invention.On-bladed fan 200 is similar to on-bladed fan 100, and its difference is: on-bladed fan 200 comprises affix storage tank 50 and flow guiding unit 52.Affix storage tank 50 is removably installed in the toroidal shell 44, and flow guiding unit 52 then is to be communicated between affix storage tank 50 and the affix outlet 448.Wherein, affix storage tank 50 can store affixs such as water, essence or insecticide.Especially, in the present embodiment, be transformed into gas for ease of making affix, on-bladed fan 200 also can comprise heating element 54.Heating element 54 for example is connected with flow guiding unit 52.Be appreciated that in other embodiments of the invention heating element 54 also can be connected with affix storage tank 50; Perhaps omit heating element 54, comprise capillary pipe structure in the flow guiding unit 52, spread out again directly affix storage tank 50 is imported to affix outlet 448 and make.
In addition, be appreciated that in other embodiments of the invention that the affix storage tank also can directly be connected with the inner passage of toroidal shell, gas outlet can be combined as a whole with the affix outlet, to save the setting of affix outlet; And other structures of on-bladed fan can be same or similar with corresponding structure in the foregoing description at this moment, repeats no more herein.
In sum, in the on-bladed fan of the embodiment of the invention, owing to be provided with the affix outlet, affix is flowed out from the affix outlet, thereby increase the additional function of use of on-bladed fan, use with the aspect.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solution of the present invention content, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
