How to make a sprayer with simple structure?

The pressure regulating component of the existing sprayer is provided with an internal thread in the pressure regulating housing, one end of the pressure regulating screw is screwed into the internal thread, and the end of the pressure regulating screw acts on the spring force of the regulating spring to make the spring control the valve The gap between the core and the valve seat is adjusted.

Because the sprayer will vibrate during the working process, a lock nut is screwed on the screw to prevent the screw from loosening due to vibration, resulting in pressure changes and affecting the effect of the sprayer.

The above structure has the following defects: First, because the pressure regulating housing needs to be equipped with springs and other parts, the diameter is larger than the pressure regulating screw, so the upper part is either closed or processed blind holes and then threaded holes, which is more complicated; , Every time you adjust the pressure, you need to loosen the lock nut and then adjust, the operation is more complicated and inconvenient to use.
