The specific dimensions and numerical values used in the present embodiment are only for illustrative purposes to illustrate the technical solutions and do not limit the scope of protection of the utility model.

[0028] As shown in Figure 1 , the utility model discloses a kind of lifting pressure type micro atomizers, which include pump body 2, install valve rod 12 in pump body, and the inner plug 11 is installed in the opening at the top of pump body 2, the valve rod 12 passes through the inner plug 11, and the O-ring 10 is installed between the valve rod 12 and the lower surface of the inner plug 11. The valve needle 6 is connected to the bottom of the valve rod 12. The head cap 14 is installed at the top of the valve rod 12, and the spray sheet 13 is installed at the liquid outlet of the head cap 14. The piston 7 is sleeved on the lower part of the valve rod 12. The bottom of the pump body 2 is the liquid inlet, and the suction tube 1 is inserted into the liquid inlet. The upper part of the suction tube 1 is a one-way valve. In the present embodiment, a steel ball 3 is used. The large ring 5 is sleeved on the opening at the top of the pump body 2, and the large ring 5 is used to install the pump body 2 on the bottle body of the atomizer. The gasket 8 is installed in the large ring 5.
