Abstract
The utility model discloses a household spinning type electric fan. Two impellers are driven to rotate by a motor simultaneously. The motor is fixed with an outer casing together. The household spinning type electric fan is structurally characterized in that each group of wind direction grid is arranged on both ends of the squirrel cage type outer casing respectively, and the wind direction grid plates drive the motor, the outer casing, etc., to rotate together because of bearing a wind thrust force which is generated by the rotating of the impellers. The utility model has the advantages of great wind rate, wide wind irradiation range, novel structure, and beautiful appearance.
Description
The utility model relates to a kind of spin type fan, belongs to civilian household appliances.
In the prior art, the structure of fan is to be dried by the motor drives single impeller basically, the angle of this fan rotation is limited, the scope of wind-force radiation is also limited, also there is the motor drives bilobed wheel to occur to the fan of two side-blowings, this kind electric fan impeller will rotate in a fixed enclosed globe shade, though solved the problem that angle is limited, the wind-force radiation scope is limited of fan rotation, but the influence that factor receptor is long-pending, the length of the motor reel of this fan that is be restricted, impeller diameter also is restricted, thereby air quantity is little.
The purpose of this utility model is to provide a kind of spin type fan, and this kind fan can be by clockwise or unidirectional rotation counterclockwise together with its outer cover, and air quantity is big, to solve the deficiency of prior art.
The purpose of this utility model is to realize like this.A kind of spin type fan, comprise motor, impeller, outer cover, strut, to two ends one impeller is installed respectively at motor shaft, motor, impeller are installed in the outer cover, the two ends that it is characterized in that the squirrel-cage shaped outer cover are separately installed with the wind direction grid, and the plane of wind direction grid and the central shaft of motor have a certain degree.When motor is worked, drive two wheel rotation, because motor, impeller are installed in the squirrel-cage shaped outer cover, wind by housing case from around be inhaled into, therefore the wind-force that is produced by wheel rotation produces pressure to the wind direction grid, when pressure in contrast that two groups of wind direction grid produce, the wind direction grid just will drive outer cover, motor, impeller together by clockwise or counter clockwise direction folk prescription to rotating around strut.Above-mentioned squirrel-cage shaped outer cover can be made into straight cylinder type, middle protruding drum type or middle recessed drum type.
Said outer cover both sides wind direction grid can be made of one group of lath respectively, and each lath is parallel to each other.Lath can be with certain radian, and such one group of lath has just formed the spherical wind direction grid of an indent evagination, and is therefore not only aesthetic in appearance, but also satisfies the requirement of air output.
Adopted the fan of said structure, not only air quantity is big, and wind-force can comprehensive radiation, and the wind-engaging scope is wide, and is aesthetic in appearance.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is that the utility model embodiment's A is to sectional view.
In the present embodiment, motor 1 adopts an axis motor, can also adopt two non-axis motor that are fixed together dorsad on same axis, at the axial two ends of motor 1 impeller 2 is installed respectively, outer cover 3 is fixedly installed on the motor 1 by axle sleeve 4.The wind direction grid 5 that are made of two groups of laths that are parallel to each other are fixedly installed in the two ends of outer cover 3.Below, motor 1 middle part is installed with back shaft 6, and back shaft 6 is connected with strut 8 by axle sleeve 7.Wherein back shaft 6 is by megohmite insulant and be insulated two-part conductive materials that material separates and constitute, axle sleeve 7 is placed in outside the back shaft, in two slip rings are arranged, these two slip rings connect power supply, and contact with the current-carrying part of back shaft 6, two-part conductive materials of back shaft 6 links to each other with motor 1 by external cord 8, and therefore, the external cord 9 of motor 1 is connected with power line by the slip ring in the axle sleeve 7.When connecting power supply, motor 1 is started working, and impeller 2 begins rotation, produce wind-force wind direction grid 5 are produced thrust, thereby the wind direction grid drive rotation together such as motor, outer cover, thereby wind-force can comprehensive radiation.
In the present embodiment, the diameter of impeller can suitably be adjusted as required.The motor shaft moderate length can satisfy the requirement of air inflow.
In the present embodiment, the switch of fan, wind speed transposing circuit and control key can be installed on strut or the base.
