The invention discloses a liquid supply
assembly, an atomization method of the liquid supply
assembly and a large-
dose atomization device. The liquid supply
assembly comprises a
medicine bottle, a
piston assembly and a push rod. The
medicine bottle comprises a pressure chamber and a
liquid storage chamber which are communicated front and back, and the front end of the pressure chamber is provided with an atomizing assembly for atomizing liquid; the
piston assembly is movably arranged on the rear portion of the
liquid storage chamber, and in the initial state, the
piston assembly is compressed by liquid in the
liquid storage chamber. The push rod movably penetrates through the piston assembly and can be matched with the pressure chamber to form a variable-volume
pump chamber structure. The liquid supply assembly can store a large amount of liquid and can be matched with the push rod to continuously and quantitatively spray, the requirement for multiple-time or long-time atomization treatment is met, and the applicability of the device is improved; the
medicine bottle has the liquid storage capacity and the pressurization effect, and the spraying effect of the device can be effectively improved; the piston assembly solves the problem that the liquid storage chamber may have an unoccupied area due to continuous liquid suction, and the stability and accuracy of follow-up quantitative liquid supply are prevented from being affected.
