发明名称 Luminescent refrigerant gauge device
摘要 A luminescent refrigerant gauge device has a body, a luminescent board, a case, a switch and a driving circuit device. The body has a valve body and a gauge body assembly. The luminescent boards are mounted inside the gauge body assembly. The case is mounted on the body. The switch is mounted inside the mounting hole in the gauge housing. The driving circuit assembly is mounted on the top of the valve body and is connected with the switch and the luminescent board. When the luminescent refrigerant gauge device is in use, a user can clearly read the measuring result of the gauge device in a dark environment without using an additional light source.
