Description

Technical Field

[0001] This utility model relates to the technical field of diving equipment, specifically a high-pressure air signal light for diving gas cylinders. It is installed on the back of the diving gas cylinder and uses its sensing component to detect the residual gas pressure in the diving gas cylinder. It emits different lights according to different pressure values ​​so that it can be quickly observed underwater or in low-light conditions to avoid regrets. Background Technology

[0002] In general, during diving activities, visibility is severely impaired due to the refraction and obstruction of light by water. Without auxiliary light sources, it is impossible to dive successfully in the deep sea. The diving cylinders, which are vital for the diver's survival, are typically equipped with a reading gauge to measure the remaining air level. However, the dim underwater environment makes it difficult to see the readings, increasing the risk of running out of air. Therefore, it is essential to carry a diving light. This underwater searchlight provides auxiliary illumination for guidance, lighting, and direction, facilitating underwater communication and allowing for easier observation of the surrounding environment and the integrity of equipment, thus ensuring safe underwater operations.

[0003] However, standard diving lights must be usable underwater and must be handheld. Constantly staring at the gauges while underwater can be quite cumbersome for divers and seriously compromise their safety. The same issue arises with other types of cylinders besides diving cylinders, such as those used for emergency rescue, welding, laboratories, beverage preparation, gas storage, fire extinguishing, heating, cooking, and water treatment. In dark, poorly lit environments, or even confined spaces, the inability to clearly read the gauges can cause significant problems. Furthermore, because diving cylinders are typically pressurized, meaning gas is compressed into a single cylinder using high pressure or cryogenics, leaks in the piping or defects in the cylinder can easily lead to evaporation. Especially underwater, such leaks can cause insufficient air supply, endangering the divers' lives. Therefore, detecting and preventing depressurization and residual air in diving cylinders is a crucial issue.

[0004] In view of this, the designer of this project, drawing on years of experience in mechanical design, has come up with a high-pressure air signal light for diving cylinders. When installed on the diving cylinder, the light can detect the residual gas pressure inside the cylinder through a built-in sensor and emit different lights according to different pressure values. This allows divers to quickly observe the operating status of the diving cylinder underwater or in low-light conditions by observing the color or intensity of the light. Utility Model Content

The plurality of airtight waterproof rings seal all gaps during assembly. Accordingly, the chip battery holder has a control circuit board on which an LED light-emitting chip and a battery are mounted and electrically connected.
