Abstract

The utility model discloses a cooling fan for displaying graphs by touch control. The cooling fan mainly comprises: a fan base, a driving part, a blade part and a control unit, wherein the blade part and the driving part are respectively provided with a first sheathing base and a second sheathing base that can be used for sheathing and combining a first coil and a second coil that are prefabricated in the shape of an annular block, so as to overcome the existing difficulty in coiling enamelled wires. The circuit board of the control unit combines with a touch pad by a flat surface, thus omitting the cost of electric connection by a conductor. Besides, as a transmitting and receiving device of the control unit corresponds to a reflecting component arranged in the fan base, the problems that two circuit boards need to be provided as the transmitting and receiving components are separately arranged in two positions and the manufacturing and assembling costs are increased, are solved.

Description

The radiation fan of touch-control type display graphics

Technical field

The utility model relates to a kind of radiation fan, relates in particular to a kind of radiation fan of touch-control type display graphics.

Background technique

Because the 3C electronic industry is flourish, the Related product of various novelty is constantly weeded out the old and bring forth the new, and in order to promote the sale of product, each tame manufacturer grinds the strange additional function of innovation one after another, to attract Consumer's attention; Wherein, a kind of touch-control type display graphics radiation fan that is applied to computer to dissipate heat is arranged on the market, it utilizes ocular vision to persist principle, adds the atwirl characteristic of fan blade, arranges in pairs or groups electronically controlled LED lamp again and produce the visual effect of display graphics or literal when fan rotates.

See also Figure 1 and Figure 2, the structure of existing touch-control type display graphics radiation fan roughly comprises:

The fan seat 1 of one tool, one pivot end 11.

One is located at the stator department 2 of the pivot end 11 of fan seat 1, it comprises the drive portion 21 of being located at a circuit board 22, one side of circuit board 22 is provided with a transmitting terminal 221, drive portion 21 with respect to an end of circuit board 22 be provided with one first coil base, 23, the first coil bases 23 outer can for first enameled cable, 231 circles around.

One has the flabellum portion 3 of a drive-connecting shaft 31, flabellum portion 3 articulates with drive-connecting shaft 31 and stator department 2, the other end that flabellum portion 3 and stator department 2 articulate be provided with second coil base, 4, the second coil bases 4 outer can for second enameled cable, 41 circles around, second coil base 4 is corresponding with first coil base 23.

See also Fig. 1, Fig. 3 and shown in Figure 4, one is located at the control circuit board 5 of the other end of flabellum portion 3 and stator department 2 pivot joints, one side surface of control circuit board 5 is provided with a plurality of electrical assemblys 51, the relative bi-side of control circuit board 5 have an Extension support 52 respectively, one side of Extension support 52 is provided with a plurality of light emitting diodes 521, the opposite side of Extension support 52 is provided with at least one sense terminal 522, and sense terminal 522 is corresponding with transmitting terminal 221; Be covered with a touch control board 6 on the electrical assembly 51 of control circuit board 5 again, between touch control board 6 and the control circuit board 5 owing to there is electrical assembly 51 to intercept, so must be by lead (scheme not shown) and control circuit board 5 electric connections.

When radiation fan starts, first enameled cable 231 of electric power transfer to the first coil base 23 and second coil base 4 and second enameled cable 41, because the interaction effect of first enameled cable 231 and second enameled cable 41, make that flabellum portion 3 is the center running with drive-connecting shaft 31, this moment, control circuit board 5 also rotated thereupon; The light emitting diode 521 of Extension support 52 is luminous and Extension support 52 fast rotational and the user is produced the effect of the persistence of vision by the control of control circuit board 5, the user can see that light emitting diode 521 rotates the literal that formation manifests, symbol or image, the user also can be by contact or near touch control board 6, make touch control board 6 thereby detecting or sense the instruction that the user sends, touch control board 6 just can conduct to control circuit board 5 by lead (scheming not shown) with command message, control circuit board 5 is controlled the variations in light of light emitting diode 521 again according to command message, and produces different literal, symbol or image effect.

Described existing touch-control type display graphics radiation fan, its structure is formed and is had many shortcomings, and it is as follows only to put the bar row in order:

One, first coil base 23 and second coil base 4 are taken as enameled wire loop drum volume, and be consuming time and bother in the process of enameled wire loop drum volume, and processing procedure is caused harmful effect.

Two, be covered with a touch control board 6 again on the electrical assembly 51 of described control circuit board 5, between touch control board 6 and the control circuit board 5 owing to there is electrical assembly 51 to intercept, so must electrically connect by lead (scheming not shown) and control circuit board 5, so not only the cost of material of lead is higher, and the assembly cost between lead and touch control board 6 and the control circuit board 5, the complexity thereby the raising of assembling, and the ulking thickness of product is also thereby increase.
