This application relates to a nitrogen humidifier, comprising a first housing, a connecting member, an air inlet pipe, a liquid inlet pipe, a second housing, a flow restrictor, and a connector. The connecting member is disposed at a first opening of the first housing and has a first air passage, an air inlet passage, and a liquid inlet passage, which are respectively connected to an external controlled air source and a liquid source. The air inlet pipe and the liquid inlet pipe respectively introduce gas and liquid into a first accommodating space for premixing. The first air passage connects to a second accommodating space of the second housing, where the flow restrictor is disposed. The flow restrictor agitates the ejected mixed airflow to achieve secondary mixing. The connector is disposed at a third opening of the second housing to exhaust the mixed gas. This nitrogen humidifier, through independent gas and liquid supply and a two-stage mixing design, effectively improves humidification efficiency and humidity stability, solving the problems of low mixing efficiency and poor humidity control in existing technologies, and is suitable for high-precision process requirements.

The utility model discloses a liftable light source lighting device for a visual inspection system, which comprises a top frame connected with a light source mounting bracket through a left telescopic bracket and a right telescopic bracket; the light source installation support is of a frame structure composed of a transverse rod and a longitudinal beam, and a light source is arranged on the transverse rod. The left telescopic bracket and the right telescopic bracket are formed by connecting scissor type brackets; a lifting driving mechanism is installed in the middle of the top frame and comprises a motor, the motor simultaneously drives left and right steel wire winding discs to rotate through a worm, and the left and right steel wire winding discs are connected with the bottoms of the left and right telescopic supports through steel wires respectively. Compared with the prior art, the light source installation support can be stable and controllable in the lifting process, the light source installation support is particularly suitable for being installed in the space position with the limited size, the structure is made of sectional materials, light weight is achieved, and operation of other mechanisms of equipment cannot be affected. The automatic control problem of vertical movement of the light source is effectively solved through the limiting sensor.
