Abstract

The controller for text and figure display of fan blade includes one driver element, one rotating part driven by the drive element, one display unit installed on the rotating part and one controller for on-off of the display unit. By means of the visual duration effect of human eyes, when the display unit is in uniform motion of motion period smaller than the visual duration time and the display unit is controlled to light and go out alternately, some continuous and stable picture will be exhibited.

Description

The character pattern display control unit of flabellum

Technical field

The present invention relates to a kind of display control unit, especially the character pattern display control unit that refers to a kind of flabellum, one display unit is installed on the rotation section of fan, when rotating in the rotation section, utilize the human eye vision persistence characteristic, can see on the movement locus of display unit that a continuous literal or a pattern manifests.

Background technology

At present electric fan become people live summer in indispensable electrical home appliances, and the cost of manufacture of electric fan is low, so many electrical equipment dealers for the sale of sales promotion electrical equipment, can bring electric fan and be used as present and give, therefore, can say that every household all has electric fan.

The above-mentioned electric fan of carrying has a motor, is connected with a flabellum on the motor.After the electric fan switch was pressed, motor can drive the flabellum rotation immediately, and with after the ambient air suction, and produce air quantity output.Also because the flabellum rotating speed is exceedingly fast, so the dealer can install a cover body additional in the flabellum outside, hinder and hit to prevent user's false touch.But the aforementioned electric fan of carrying all is traditional design, and adding present every household all has under the situation of cold air, and consumer's desire to purchase reduces greatly.

Summary of the invention

Because some dealers are made into a transparence with the flabellum body again at present, when rotating, sometimes be difficult to find out that whether this flabellum is in rotation, in case child will point when inserting cover body inside, easily causing into finger is hit by flabellum, cause and to smear the injury of going out, therefore fundamental purpose of the present invention is to solve above-mentioned scarce arrow, avoid disappearance to exist, and a kind of character pattern display control unit of flabellum is provided, a display unit is installed, when rotating in the rotation section on the rotation section of fan, utilize the human eye vision persistence characteristic, can see on the movement locus of display unit that a continuous literal or a pattern manifests.

Another object of the present invention is to shown character pattern and can be house mark, advertising design, perhaps have warning literal or pattern, to reach the purpose that advertising or warning are sold in marketing.

For reaching above-mentioned purpose, utilize a display control unit to be installed on the rotation section of fan, when the rotation section is subjected to the actuation element driven in rotation, after this display control unit driving display unit is done the flicker of light on and off, and utilize human eye vision to persist state, character and picture can keep the time of about 40MS in human brain, can see manifesting and changing of a continous-stable character pattern on the moving surface of rotation section.

Embodiment

Referring to Fig. 1, the embodiments of the invention synoptic diagram, as shown in the figure: the character pattern display control unit of fan of the present invention, on the rotation section (flabellum) 2 that display control unit 1 is installed on fan, when rotation section 2 is subjected to actuation element (or motor of fan) 3 driven in rotation, after this display control unit 1 driving LED array element 13 is done the flicker of light on and off, and utilize human eye vision to persist state, character and picture can keep the time of about 40MS in human brain, can see the manifesting and change of character pattern of a continous-stable on 2 moving surfaces of rotation section.

Referring to Fig. 2,3,4, speed control of the present invention and led array control circuit square and conspectus.As shown in the figure: character pattern display device of the present invention includes: a power supply unit 11, a driver element 12, a led array unit 13 and activate element 3 and form.Aforesaid power supply unit 11 is except providing the required power supply of display device, also contain a speed-stabilizing circuit 111, this speed-stabilizing circuit 111 makes actuation element 3 stabilizations of speed on any metastable rotating speed, led array unit 13 on the rotation section 2 is occurred on the pattern or the movement locus face of literal in led array unit 13 of preface meter, as shown in Figure 6 when rotating.

There is driving LED array element 13 to make the software bright and flicker of going out in this driver element 12;

The design of this led array unit 13, suppose that led array unit 13 is made up of 7 LEDs, to on plane of rotation, demonstrate one " E " word pattern, actuation element 3 rotating speeds are 2400 rev/mins, then answer the driving of following design 7 LEDs: we can become dot matrix to picture breakdown, " E " word is by the standard dot matrix " E " of 5*7, because the actuation element rotating speed is 2400 rev/mins, promptly rotating the used time of circle is 25ms, if we are divided into 72 points rotating a circle, then a circle can show 12 letters (72/ (5+1)) at most, wherein each word interval a bit, the time of lighting each some usefulness then is 374us, therefore, show " E " word, then the control timing figure as Fig. 5 is used in the driving of 7 LEDs.

Therefore, utilize the human eye vision persistence characteristic, this pattern can keep the time of about 40MS in human brain, use actuation element 3 or other power to drive led array unit 13 and make uniform motion, as long as the time period of motion is less than the time of persistence of vision, re-use the on and off of driver element 12 or other Digital Circuit Control led array unit 13, human eye just can be seen the picture that a width of cloth is continuous and stable on the movement locus face of led array unit 13.

Further, pattern that the present invention is shown or literal can be house mark, advertising design or some warning literal or pattern, to inform child, avoid the flabellum of child's false touch fan.

It should be noted that above-mentioned is embodiments of the invention only, and is not to be used to limit the present invention.All equalizations of doing according to claims of the present invention change and modify, all should be in the scope of this patent protection.
