Diffusion sheet diffusion particle preparation device and method

Abstract

The invention discloses a diffusion sheet diffusion particle preparation device. The device comprises an injection part, an atomizing part and an energizing part, wherein the injection part comprisesa precise injection pump and a liquid supply pipe; the atomizing part comprises a static atomizer and a diffusion base material, wherein the static atomizer comprises needles and an isobaric cavity accommodating a solution, the precise injection pump provides pump pressure which acts on the solution in the static atomizer, all the needles are communicated with the isobaric cavity, and pressure ata liquid supply pipe interface acts on the solution in the isobaric cavity; the static atomizer further comprises electrode slices in contact with the needles, the electrode slices are connected witha high voltage power supply box, the diffusion base material is located below the static atomizer, an electrode board is arranged on the bottom of the diffusion base material, the electrode board is connected with the high voltage power supply box, and the solution forms atomized liquid drops under the action of the electrode slices, the electrode board and the high voltage power supply box afterbeing sprayed by the needles, so that diffusion particles are formed on the diffusion base material. The invention further discloses a diffusion sheet diffusion particle preparation method.

Description
