Abstract
The invention discloses a silent fan without an exposed vane. The silent fan is characterized by comprising a base and a shell which is arranged on the base, wherein a wind inlet structure is formed on the back face of the shell, a mask is covered on the front face of the shell; the mask is provided with a plurality of wind outlet structures; an inertial flow fan wheel and a motor which is used for driving the inertial flow fan wheel to rotate are arranged between the shell and the mask; a control circuit is arranged in the base; and a control knob connected with the control circuit is arranged on the base. The silent fan without the exposed vane, provided by the invention, not only can ensure the safety in use, but also is very low in noise, so that a user can enjoy perfect silent experience, and the using comfort is improved.
Description
Technical field
The present invention relates to a kind of fan, be specifically related to the quiet fan that a kind of nothing exposes fan blade, belong to household appliance technical field.
Background technique
Fan is the cooling electrical equipment that a lot of families adopted in summer, but traditional fan vane exposes, and safety in utilization is lower, especially has child's family to need in use particularly prudent; Development along with technology, a kind of fan that does not have flabellum has also appearred in the market, because its inventor is Dai Sen, so this machine is known as again " wearing gloomy air multiplier ", cardinal principle is at the pedestal air amount, then air is led into annulus, and the sealing from ring sprays, the drive ambient air flows, and produces comparatively comfortable wind.It is exactly that noise is very large that but there is a problem in this kind equipment, because turbine is arranged in the base, the size of turbine is restricted, cause the turbine small volume, in order to obtain comparatively comfortable wind, just need to realize by the rotating speed that improves motor, so just must cause noise very large.Also do not have at present a kind of fan can ensure Security when using, can obtain again the travelling comfort of quiet experience.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to overcome the defective of prior art, provide a kind of nothing to expose fan blade, ensure the Security of using, be used to flow wind wheel by setting simultaneously and guaranteed lower noise, improved the travelling comfort when using.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
Without the quiet fan that exposes fan blade, it is characterized in that, comprise base and the housing that is arranged on the base, above-mentioned back side of shell is formed with air inlet structure, above-mentioned housing front is coated with face shield, be formed with some air exhausting structures on the above-mentioned face shield, be equipped with between above-mentioned housing and the face shield to be used to flow wind wheel and to drive and be used to flow the motor that wind wheel rotates, be provided with control circuit and base in the above-mentioned base and be provided with the control handle that is connected with control circuit.
Aforesaid nothing exposes the quiet fan of fan blade, it is characterized in that, above-mentioned face shield is circular.
Aforesaid nothing exposes the quiet fan of fan blade, it is characterized in that, above-mentioned air inlet structure is a plurality of through holes that are formed at back side of shell.
Aforesaid nothing exposes the quiet fan of fan blade, it is characterized in that, above-mentioned air exhausting structure is the circular port that is formed on the face shield.
Aforesaid nothing exposes the quiet fan of fan blade, it is characterized in that, above-mentioned control handle comprises air quantity adjusting knob and time set knob.
Aforesaid nothing exposes the quiet fan of fan blade, it is characterized in that, above-mentioned housing can rotate with respect to base.
Usefulness of the present invention is: nothing of the present invention exposes the quiet fan of fan blade, the Security in the time of not only can guaranteeing to use, and also noise is extremely low, and the user can enjoy outstanding quiet experience, has improved the travelling comfort when using.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of the nothing of the present invention quiet fan that exposes fan blade.
The implication of reference character among the figure: 1, base, 2, housing, 3, face shield, 4, air exhausting structure, 5, the air quantity adjusting knob, 6, the time set knob.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
Referring to Fig. 1, nothing of the present invention exposes the quiet fan of fan blade, comprises base 1 and the housing 2 that is arranged on the base 1.Wherein, housing 2 back sides are formed with air inlet structure, housing 2 fronts are coated with face shield 3, be formed with some air exhausting structures 4 on the face shield 3, be equipped with between housing 2 and the face shield 3 to be used to flow wind wheel and to drive and be used to flow the motor that wind wheel rotates, be provided with control circuit in the base 1 and base 1 is provided with the control handle that is connected with control circuit.
Need to prove that owing to the visual angle reason, some parts fails to display in the drawings, in view of these parts all are to understand easily and can explanatory note, so need not to show in the drawings more in addition.
As a kind of preferred, face shield 3 is circular.We said the front, being used to flow wind wheel is arranged between face shield 3 and the housing 2, its volume can be larger, as long as can hold with housing 2 in, so, reach preferably using effect (being the air quantity requirement), under slower rotating speed, just can realize, thereby the noise of this fan is very low, can satisfy well client's quiet experience.
As a kind of concrete structure, air inlet structure is a plurality of through holes that are formed at housing 2 back sides, and shape is not restricted, as long as can guarantee that enough air outputs are just passable.
Further, air exhausting structure 4 is for being formed at the circular port on the face shield 3, and as shown in Figure 1, circular port is evenly distributed on the face shield 3, so that air-out is even, and then has improved comfort level.
As a kind of preferred, control handle comprises air quantity adjusting knob 5 and time set knob 6.
As further improvement, housing 2 can with respect to base 1 rotation, can be applicable to the user demand of multi-angle flexibly.
More than show and described basic principle of the present invention, major character and advantage.The technician of the industry should understand, and embodiment does not limit the present invention in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
