The design of the plastic continuous spray bottle is actually very simple, and the basic principle is the principle of pipe pumping. The main design is on the bottle mouth, that is, a bottle head must be installed on the bottle mouth. The bottle head mainly relies on a trigger, the trigger can trigger a small water pump, and then the water pump is connected to a plastic tube, this straw can suck the contents of the bottle from the bottom of the liquid reservoir, of course, this can only be used for liquid or sticky liquid. Thick lotion. The pump then presses the liquid into a narrow cavity and sprays it out of a small hole in the sprayer's nozzle. The viscosity of the liquid determines the size of the nozzle and the thickness of the plastic tube.

    The movable element of the hydraulic pump in the design of the spray plastic bottle is a piston, which is located in a cylindrical hydraulic chamber, and there is a small spring in the hydraulic chamber. When the hydraulic chamber is pushed, the moving piston compresses the spring. When the wrench is released, the piston is pushed out of the hydraulic chamber again. The two strokes of the piston entering and leaving the hydraulic chamber constitute a complete pump cycle.
