Abstract
The utility model discloses a direct current fan, including the frame, the inside of frame is inlayed and is had the inside casing, and middle part sets up the district into gas flow between frame and the inside casing, and the exhaust vent of efflux of gas is all seted up to the both sides face of frame, and the inside casing side sets up as the fresh air inlet that carries out absorbing gas through brushless motor, is provided with the mixed flow impeller that mixs gas flow around the inside casing. Simple structure, the appearance can produce the nice and cool air of powerful just as the ring, has advantages such as wind pressure suction is strong, can effectual use on air purifier, the excellent and environmental protection of energy -conserving performance, simultaneously, the security performance is excellent, and the noise that produces when not depositing fan cutting air, the silence is effectual, practicality is excellent, the modern design is a fine innovation scheme, has very much the marketing prospect.
Description
Technical field
The utility model relates to air purifying process, particularly relates to a kind of DC fan.
Background technique
Purifier air cleaner is also known as " air cleaner ", air cleaner, purifier, refer to and can adsorb, decompose or transform various air pollutant (generally comprising the finishing pollution of PM2.5, dust, pollen, peculiar smell, formaldehyde and so on, bacterium, anaphylactogen etc.), along with people start the attention of the gaseous contamination after to air quality and finishing, air cleaner commercially starts fast-selling gradually.The product of effective raising air cleanliness, mainly be divided into family expenses, commercialization, industry, building etc., but, purification series products is in the market in the process used, the noise that the blade cuts air of fan produces is also larger, interference daily life, also exists certain deficiency, does not meet the trend of social development.
In sum, for the defect of prior art, a kind of DC fan of special needs, to solve the deficiencies in the prior art.
Model utility content
For the deficiency that purifier fan in prior art also exists, and in the process of reality, cause very large impact, the utility model proposes a kind of DC fan, novel in design, without the need to flabellum, and can continue nice and cool natural wind is provided, effectively can improve the air of ours at one's side, practicability is excellent, addresses the deficiencies of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of DC fan, comprise housing, the inside of housing is inlaid with inside casing, part in the middle of between housing and inside casing is set to gas Circulation Area, the bi-side of housing all offer the exhaust vent of gas outflow, inside casing side is placed through the intake opening that brushless electric machine carries out absorbing gas, and the surrounding of inside casing is provided with the mixed-flow impeller stirring gas flow.
Further, the shape of described housing and inside casing composition is ring.
The surrounding of housing described in the utility model is provided with fixing convergence hole, and the quantity of fixing convergence hole is four.
Further, the blade of described mixed-flow impeller is seven, and mixed-flow impeller is shape ringwise.
The beneficial effects of the utility model are: this product structure is simple, and profile, just as finger ring, can produce strong cool air, there is the advantages such as blast suction is strong, can effectively be used in above air cleaner, the excellent and environmental protection of energy-efficient performance, simultaneously, Safety performance is excellent, and the noise produced when not depositing fan cutting air, muting function is good, practicability is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is detonation configuration schematic diagram of the present utility model.
Fig. 2 is the utility model perspective view.
Fig. 3 is the utility model cross-sectional structure schematic diagram.
Fig. 4 is the utility model Facad structure schematic diagram.
100-housing in figure, 110-exhaust vent, 120-fixes convergence hole, 130-intake opening, 140-mixed-flow impeller, 150-inside casing, 160-brushless electric machine, 170-gas Circulation Area.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of DC fan, comprise housing 100, the inside of housing 100 is inlaid with inside casing 150, part in the middle of between housing 100 and inside casing 150 is set to gas Circulation Area 170, the bi-side of housing 100 all offer the exhaust vent 110 of gas outflow, and inside casing 150 side is placed through the intake opening 130 that brushless electric machine 160 carries out absorbing gas, and the surrounding of inside casing 150 is provided with the mixed-flow impeller 140 stirring gas flow.
In addition, the shape that housing 100 and inside casing 150 form is ring.The surrounding of housing 100 is provided with fixing convergence hole 120, and the quantity of fixing convergence hole 120 is four.The blade of mixed-flow impeller 140 is seven, mixed-flow impeller 140 shape ringwise.
Principle of the present utility model be when have a branch of air-flow rapidly by time, it can pull ambient air, and by them, and then it moves together.When air-flow blows out from the finedraw of 1 mm wide with the speed per hour of 55 miles, it will be entrained with the air of periphery together forward; Produce negative pressure, the air pressure after annulus can reduce, and causes the more air in rear to add with equilibrium air pressure, and the air quantity of air cleaner is significantly enlarged, and reaches 15 times of the own extraction amount of mixed-flow impeller, is finally produced by boasting by the finedraw of exhaust outlet.
The utility model is effective is: structure is simple, and profile, just as finger ring, can produce strong cool air, there is the advantages such as blast suction is strong, can effectively be used in above air cleaner, the excellent and environmental protection of energy-efficient performance, simultaneously, Safety performance is excellent, and the noise produced when not depositing fan cutting air, muting function is good, practicability is excellent, modern design, is a kind of well innovation scheme, has very much marketing prospect.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
