The invention discloses a water depth display device and an underwater walking stick. The water depth display device comprises a power source, a water depth sensor, a circuit board and an indicator lamp set, the indicator lamp set is electrically connected to the circuit board and comprises multiple indicator lamps connected in series, the positive electrode of the indicator lamp set is connected with the positive electrode of the power source, the negative electrode of the indicator lamp set is connected with the negative electrode of the power source, and the water depth sensor is connected with the indicator lamp set in series; and the lightening currents of the indicator lamps are different, the lightening currents of the indicator lamps correspond to different water depth values, and the magnitude of the lightening currents is in positive correlation with the water depth values. When the water depth display device is under water, the resistance value of the water depth sensor can change along with the change of the water depth, then the current magnitude of the indicator lamp set is changed, different currents can lighten different indicator lamps, and the lighted indicator lamps prompt the corresponding water depth. A user can intuitively know the instant water depth of the current water area by turning on the indicating lamp.

    本发明公开了一种水深显示装置及水下拐杖。本发明的水深显示装置包括电源、水深传感器、电路板和指示灯组,指示灯组电连接于电路板上,指示灯组包括串联连接的多个指示灯,指示灯组的正极连接电源的正极,指示灯组的负极连接电源的负极,水深传感器与指示灯组串联连接;多个指示灯的点亮电流各不相同,各个指示灯的点亮电流对应不同的水深值,且点亮电流的大小与水深值呈正相关关系。本发明的水深显示装置在水下时,水深传感器的阻值会随着水深的变化而变化,进而改变指示灯组的电流大小,不同大小的电流能点亮不同的指示灯,亮起的指示灯提示对应的水深,使用者通过点亮的指示灯便可以直观地知道自己当前所处水域的即时水深。
