Abstract
The invention discloses a bladeless fan, aiming at providing a bladeless fan with double air outlets. The bladeless fan is characterized by comprising a nozzle with an opening and an airflow device, wherein the airflow device is used for generating airflow passing through the nozzle; the nozzle comprises a first shell and a second shell; a first shell opening and a second shell opening are formed on the first shell and the second shell respectively, and are oppositely arranged; the end of the first shell opening at the opposite position is smaller than that of the second shell opening, and is positioned in the end of the second shell opening at the opposite position; the first shell opening and the second shell opening form overlapping parts at the opposite position; gaps are formed on the overlapping positions; and air outlets are formed on the gaps. Compared with the prior art, one more air outlet is formed on the bladeless fan, so that the wind blowing range is enlarged, and people feel cooler.
Description
Technical field
The present invention relates to a kind of no blade fan, more particularly, it relates to a kind of no blade fan of two outlets.
Background technique
At present, most fan still is common fan on the market, promptly blade-carrying fan, and this fan carries dust easily, and not easily removable and washable, and the setting of blade also has certain danger.In 2009, Britain has released no blade fan for the first time, and this no blade fan is not because there is blade, and energy-saving and environmental protection more, safety become.Application number is that 200910253241 Chinese patent discloses a kind of no blade fan, it comprises nozzle and the device that is used to form by the air-flow of this nozzle, this nozzle comprises inner passage, mouth and the spacing means that is used to receive air-flow, wherein air communication is crossed mouth and is launched, this mouth is limited by the apparent surface of nozzle, and spacing means is used to separate the apparent surface of nozzle, nozzle limits an opening, is dragged from the air-flow of described mouth emission from the fan component air outside and inhales by described opening.Though this no blade fan energy-saving and environmental protection, safety, because opening is limited by the size of nozzle, the scope of the wind that can distribute also just is defined.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of diffusing demeanour to enclose big no blade fan.
For achieving the above object, the invention provides following technological scheme: a kind of no blade fan, comprise the nozzle and the airflow apparatus that are provided with opening, this airflow apparatus is used to produce the air-flow that passes this nozzle, described nozzle comprises first housing and second housing, first housing and second housing are respectively equipped with first housing opening and second housing opening, first housing opening and the second housing opening opposite disposed, described first housing opening in the end at opposed place less than the end of second housing opening at opposed place, and first housing opening is in the end of second housing opening at opposed place in the end at opposed place, first housing opening and second housing opening form overlapping portion at opposed place, described overlapping part is equipped with the gap, and described gap forms gas port.By adopting technique scheme, Duoed an exhaust outlet than general no blade fan, increased the scope of diffusing wind.
Described first housing is the curved annular structure.By adopting technique scheme, make outward appearance seem not only streamline but also salubrious, wind energy distributes along the arc shape of first housing simultaneously.
Described second housing is a ring structure, and second housing includes the inclined-plane of two opposite disposed, and two inclined-planes are close gradually along the direction that deviates from first housing.By adopting technique scheme, further strengthened visual effect, also enlarged the range of scatter of wind simultaneously.
The inclined-plane of the described second housing close gradually the other end relatively is provided with arc tips, and the arc tips port is less than the inclined-plane port.By adopting technique scheme, wind is assembled owing to port diminishes in arc tips, distributes afterwards, can increase the dynamics of distributing of wind like this.
Described airflow apparatus comprises intake grill and blower fan, and blower fan is arranged between nozzle and the intake grill.By adopting technique scheme, make structure rationalization.
Description of drawings
Fig. 1 does not have blade fan embodiment's structural representation for the present invention;
Fig. 2 does not have blade fan embodiment's sectional view for the present invention;
Fig. 3 is the A portion enlarged view of Fig. 2.
Embodiment
Not having blade fan embodiment referring to figs. 1 through 3 couples of the present invention is described further.
A kind of no blade fan, comprise the nozzle 2 and the airflow apparatus 1 that are provided with opening, this airflow apparatus 1 is used to produce the air-flow that passes this nozzle 2, described nozzle 2 comprises first housing 21 and second housing 22, first housing 21 and second housing 22 are respectively equipped with first housing opening 211, second housing opening 221, first housing opening 211 and second housing opening, 221 opposite disposed, described first housing opening 211 in the end at opposed place less than the end of second housing opening 221 at opposed place, and first housing opening 211 is in second end of housing opening 221 at opposed place in the end at opposed place and (it should be noted that herein, the opening that the mode of first housing opening 211 and second housing opening, 221 opposite disposed can be set to two housings is on the same straight line in the end at opposed place, for making air-out effect more obvious, present embodiment is preferred, second housing opening 221 is in the end of first housing opening at opposed place in the end at opposed place), first housing opening 211 and second housing opening 221 form overlapping 213 at opposed place, 223,214,224, described overlapping 213,223,214,224 are equipped with gap 23,24, described gap 23,24 form gas port.Traditional no blade fan exhaust outlet air-out scope is little, and the loose scope of wind of the no blade fan exhaust outlet that the exhaust outlet that no blade fan of the present invention has utilized the opposite disposed of two housings to form is more general is big.
Described first housing 21 (it should be noted that for the curved annular structure herein, first housing 21 that the present invention does not have blade fan can be U-shaped or other geometrical shapies, for making outward appearance seem not only streamline but also salubrious, feel comfortable to the people, and air-out effect is more obvious, present embodiment is preferred, and first housing 21 is the curved annular structure).
Described second housing 22 is a ring structure, include two inclined-planes 225, two inclined-planes 225 (it should be noted that along the direction that deviates from first housing 21 is close gradually herein, described inclined-plane 225 can separate gradually along the direction that deviates from first housing 21, further strengthened visual effect, also can enlarge simultaneously the range of scatter of wind, present embodiment is preferred, and described inclined-plane 225 is close gradually along the direction that deviates from first housing 21).
The inclined-plane 225 relative close gradually the other ends of described second housing 22 are provided with arc tips 223,224, and arc tips 223,224 ports are less than the inclined-plane port.
Described airflow apparatus 1 comprises intake grill 11 and blower fan 12, and blower fan 12 is arranged between nozzle 2 and the intake grill 11.Make structure rationalize more.
Embodiment of the invention specific operation are as follows: when no blade fan starts, after 11 suck air of the suction port in the airflow apparatus 1, keep watch by the work of blower fan 12 and to deliver to nozzle 2, so wind is sent from the air outlet (gap) 23,24 of nozzle 2.
