High-pressure jet nozzle device of oil smoke pipeline cleaning robot

Abstract

The utility model discloses a high-pressure jet nozzle device of an oil smoke pipeline cleaning robot, which comprises a nozzle, the nozzle is connected with a spray head in a sealed plug-pull manner, and the spray head can be locked by a locking component. As the inner diameter of a limiting seat is smaller than that of a water inlet of the nozzle, when water flows through the limiting seat, the limiting seat can be pushed to move; when the water flow does not exist, the water flow drives the limiting rod to move, the limiting rod pushes the limiting block to move and be inserted into a first limiting groove formed in the inner wall of the connecting end of the spray head, the impact force of the water flow always pushes the limiting block to be inserted into the first limiting groove, and the higher the water pressure is, the higher the thrust to the limiting seat is, so that the spray head is locked more tightly by the limiting block; the limiting base is pushed to move through the elastic force of the spring, the limiting block can also be inserted into the first limiting groove, during unlocking, the spray head is pulled outwards, and due to the fact that the end, inserted into the spray head, of the limiting block is an arc-shaped structural part, when the pulling force is larger than the elastic force of the spring, locking of the spray head can be relieved.
