Technical Field
The utility model relates to a fan unit field especially relates to a fan.
Background
Fan refers to a tool for cooling by generating wind in hot days. The electric fan is a device which is driven by electricity to generate airflow, and the fan arranged in the electric fan rotates after being electrified, so that natural wind is formed to achieve the effect of cooling. At present, fan blades of a fan are generally fixedly connected with a motor through a rotating shaft, and disassembly and assembly cannot be realized; therefore, when the fan blades need to be cleaned, the fan blades can be cleaned only by wiping, and the cleaning is not clean enough.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fan convenient to dismouting flabellum.
The technical scheme of the utility model as follows:
a fan comprises a driving motor, fan blades and a fan housing; the fan is characterized in that a stator coil assembly of the driving motor is arranged on a rear screen cover of the fan outer cover; and a magnet ring movably connected with the stator coil assembly is arranged in the accommodating cavity in the center of the fan blade.
The center of the containing cavity is provided with a positioning shaft.
The stator coil assembly includes a circuit board and a stator coil mounted on the circuit board.
The rear mesh enclosure of the fan outer cover is connected with the front mesh enclosure of the fan outer cover through a detachable device.
The detachable device comprises clamping grooves uniformly distributed on the front mesh enclosure frame and cards uniformly distributed on the rear mesh enclosure frame.
The clamping groove is L-shaped. Because the draw-in groove is L shape, corresponding card also is L shape structure, when the installation, only need rotatory back screen panel with the card go into the draw-in groove can.
The rear mesh enclosure is provided with an ear seat for mounting a stator coil assembly; the ear seat comprises an upper mounting part and a lower supporting part; the installation department center is equipped with the erection column that uses with the location axle cooperation.
And the center of the stator coil is provided with a mounting hole matched with the mounting column.
And the support part is also provided with a power line flange.
The utility model has the advantages that: the magnetic connection of the fan blades and the driving motor is realized through the matching of the magnetic ring and the stator coil assembly, the connection mode is firm, the disassembly is more convenient, and the fan blades are conveniently cleaned independently.

in the drawing, 1 is the card, 2 is the flabellum, 3 is the fan dustcoat, 4 is the back screen panel, 5 is for holding the chamber, 6 is the magnetic ring, 7 is the location axle, 8 is the circuit board, 9 is the stator coil, 10 is the preceding screen panel, 11 is the draw-in groove, 12 is the ear seat, 13 is the installation department, 14 is the erection column, 15 is the mounting hole, 16 is the supporting part, 17 is the power cord flange.
Detailed Description
Referring to fig. 1-2, a fan includes a driving motor, fan blades 2, and a fan housing 3; the fan is characterized in that a stator coil assembly of the driving motor is arranged on a rear mesh enclosure 4 of a fan outer cover; and a magnet ring 6 movably connected with the stator coil assembly is arranged in the accommodating cavity 5 in the center of the fan blade. The magnetic connection of the fan blades and the driving motor is realized through the matching of the magnetic ring and the stator coil assembly, the connection mode is firm, the disassembly is more convenient, and the fan blades are conveniently cleaned independently.
And a positioning shaft 7 is arranged in the center of the accommodating cavity. The positioning shaft is arranged to play a certain supporting effect on one hand and play a certain guiding effect when the fan blades are installed on the other hand.
The stator coil assembly includes a circuit board 8 and a stator coil 9 mounted on the circuit board. The stator coil is controlled to work by arranging a circuit board; the fan blades are driven to rotate by the stator coils.
The rear mesh enclosure of the fan outer cover is connected with the front mesh enclosure 10 of the fan outer cover through a detachable device. Because the rear mesh enclosure and the front mesh enclosure of the fan outer cover are detachably connected, the fan outer cover is convenient to disassemble and assemble.
The detachable device comprises clamping grooves 11 uniformly distributed on the front mesh enclosure frame and cards uniformly distributed on the rear mesh enclosure frame. The card and the clamping groove are matched and installed to realize detachable connection.
The clamping groove is L-shaped. Because the draw-in groove is L shape, corresponding card also is L shape structure, when the installation, only need rotatory back screen panel with the card go into the draw-in groove can. By adopting the L-shaped structure, a certain guiding effect is achieved; when the card clamping device is used, the front net cover and the rear net cover are spliced together, and then the rear net cover is rotated to transfer a card into the clamping groove to realize clamping.
The rear mesh enclosure is provided with an ear seat 12 for mounting a stator coil assembly; the ear mount comprises an upper mounting portion 13 and a lower support portion 16; the installation portion center is equipped with the erection column 14 that uses with the location axle cooperation. One end of the positioning shaft is connected with the fan blades, and the other end of the positioning shaft is inserted into the guide groove of the mounting column, so that the mounting and guiding are facilitated.
And the center of the stator coil is provided with a mounting hole 15 matched with the mounting column. The stator coil is convenient to mount through the matching of the mounting hole and the mounting column.
A power cord flange 17 is also mounted on the support portion. And a power line baffle is arranged to block a power line of the stator coil.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
