At this time, due to the pressure difference between the two sides of the spray liquid, the high pressure gas in the high pressure bottle 40 pushes the spray liquid upward into the connecting pipe, flows along the connecting pipe to the middle channel 53 and then to the upper mounting cavity 51, then flows out from the outlet 63 and flows to the liquid storage tank cavity 62, then flows upward from the flow guide 107, then flows through the lower pressurized flow channel 106, the lower nozzle inlet channel 101, the transition cavity 103, and the upper nozzle inlet channel 102, then flows from the connecting channel to the circulation chamber 104, and finally sprays out from the upper outlet 233 through the end cap spray hole 1122.

[0022] The nozzle mechanism of this utility model features multiple vertically penetrating grooves evenly distributed on the inner wall of the upper nozzle shell, and multiple vertically penetrating grooves evenly distributed on the outer wall of the lower inner core. The depth of the inner core grooves is greater than that of the upper nozzle grooves, allowing for more uniform pressurization of the spray liquid. Combined with the end cap circulation groove on the bottom wall of the upper nozzle end cap, the spray liquid circulates and rotates before being ejected at high pressure from the end cap nozzle hole, forming a finer and more uniform mist. In addition, this utility model has a simple and compact structure and is easy to install.

[0023] It should be noted that, in addition to the three mentioned above, the number of the inner core through groove 1221, the upper mouth through groove 1111, and the end cap through groove 1123 can also be four, five, or other suitable numbers.
