Description of the Invention (1) This creation is about a text-pattern display control device for a fan blade, especially a display unit installed on the rotating part of the fan When the rotating part is rotated, a continuous character or pattern can be seen on the display unit's motion trajectory by utilizing the visual retention characteristics of the human eye. It is known that at present, electric fans have become an indispensable home appliance in people's summer life, and the manufacturing cost of electric fans is low. Therefore, in order to promote the sales of certain electric appliances, many electric appliance manufacturers will use electric fans as gifts. It can be said that every household has electric fans. The electric fan mentioned above has a motor, and a blade is fixedly connected to the motor. After the electric fan switch is pressed, the motor can immediately drive the fan to rotate, and the surrounding air is sucked in to generate a wind output. Also, because the fan blade rotates extremely fast, the industry will install a cover on the outside of the fan blade to prevent users from accidentally touching it. However, the fans mentioned above are traditional designs, and now that there is air-conditioning in homes, consumers' purchase desires are greatly reduced. At present, some manufacturers have made the fan blade body into a transparent shape. When it is rotated, it is sometimes difficult to see whether the fan blade is rotating. Once a child inserts his finger into the cover, it is easy to cause the finger to be trapped. The fan blade hits, causing indelible damage; 诿 Yes, the main purpose of this creation is to solve the above-mentioned shortcomings and avoid the existence of the shortcomings. This creation installs a display unit on the rotating part of the fan. When the rotating part rotates, Utilizing the characteristics of human vision persistence, a continuous text or pattern can be seen on the movement track of the display unit. Another purpose of this creation is that the displayed text pattern can be a company logo, advertising pattern, or have warning text or patterns to achieve marketing.

Purpose of invention description (2) or warning. In order to achieve the above purpose, a display control device is installed on the rotating part of the fan. While the rotating part is driven to rotate by the actuating element, the display control device drives the display unit to blink on and off, and then uses human eyes. In the state of visual persistence, the text image can remain in the human brain for about 40MS, and the continuous and stable text pattern can be seen and changed on the moving surface of the rotating part. It is the detailed description and technical content of this creation, and it is illustrated with drawings as follows: [Schematic description] Figure 1 is a schematic diagram of the embodiment of this creation. Figure 2 is a block diagram of the speed control circuit of this creation. Figure 3 is a block diagram of the LED array control circuit created in this work.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Please refer to "shown in Figure 1" for a schematic illustration of this creative example. As shown in the figure: The text pattern display control device for the fan of this creation is used to install the display control device 1 on the rotating part (fan blade) 2 of the fan, and the actuating element (or the motor of the fan) is received on the rotating part 2 3 While driving and rotating, the display control device 1 drives the LED array unit 1 3 After flashing on and off, and using the state of visual retention of the human eye, the text image can be retained in the human brain for about 40MS, which can be A continuous and stable character pattern appears and changes on the moving surface of the rotating part 2. Please refer to the “Figures 2, 3, and 4” for a block diagram and circuit diagram of the speed control and LED array control circuit of this creation. As shown in the picture: This creation '丨 —— ---- _-η This paper size applies to Chinese National Standard (CNS) Α4 size (210X 297 mm) ~ 502090 A7 B7 V. Description of the invention (3) Please read first The text-pattern display device, which is further filled in with attention, includes: a power supply unit 1 1, a drive unit 1 2, an LED array unit 13, and an actuating element 3. In addition to providing the power required for the display device, the aforementioned power supply unit 1 1 also contains a speed stabilization circuit 1 1 1. This speed stabilization circuit 1 1 1 stabilizes the rotation speed of the actuating element 3 at any relatively stable rotation speed, so that When the LED array unit 1 3 on the rotating part 2 rotates, a sequence pattern or text appears on the movement track surface of the LED array unit 13 as shown in FIG. 6; The driving unit 12 includes a driving LED array unit. 1 3 Do the software for turning on and off flicker; The design of the LED array unit 13 is based on the assumption that the LED array unit 13 is composed of 7 LEDs, and an "E", word pattern, and actuating element should be displayed on the rotating surface. 3 rotation speed is 2400 rpm, we should design the drive of 7 LEDs as follows: we can decompose the image into dot matrix, the "E" word is composed of 5 * 7 standard dot matrix "P", because the speed of the actuating element is 2400 rpm, that is, the time it takes to make one revolution is 25 ms. If we divide one revolution into 72 points, a maximum of 12 letters (72 / (5 + 1)) can be displayed in one revolution, each of which The words are spaced one point apart, and the time taken to light up each point is 3 74us, so a "E" ", The driving application of 7 LEDs is as shown in the control timing chart in Figure 5. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, this pattern can be retained in the human brain using the visual retention characteristics of the human eye. 4 0MS time, use the actuating element 3 or other power to drive the LED array unit 13 for a uniform speed movement, as long as the cycle time of the movement is less than the time of visual retention, then use the drive unit 12 or other digital circuits to control the LED array unit 1 3 When the light is on or off, the human eye can see a continuous and stable picture on the movement track surface of the LED array unit 1 3. Further, the pattern or text displayed in this creation can be a company trademark, and this paper size is applicable China National Standard (CNS) Α4 specification (210 × 297 mm)
