本文介绍的时钟,避开了现有时钟用指针、LED、液晶等来显示时间的设计思路,而用喷泉来数显时间,既新颖又实用。一、机理喷泉式数显时钟电路原理及结构形式分别如图1、图2所示。它由时钟IC、数显笔划输出控制电路、电泵控制电路等组成。其结构是将喷泉管道加工成图2所示的数字形,在每个笔划 This article introduces the clock, to avoid the existing clock with a pointer, LED, LCD, etc. to display the design time, and digital time with the fountain, both novel and practical. First, the mechanism Fountain digital clock circuit principle and structure are shown in Figure 1, Figure 2. It consists of clock IC, digital strokes output control circuit, pump control circuit and other components. Its structure is the fountain pipe processing into the digital form shown in Figure 2, in each stroke
