Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] The core of the present invention is to integrate the parts that realize the sampling function and the parts that realize the function of aerosol aggregation and ejection, replace the traditional collision sampler 02 and focusing nozzle 03, and save the connection between the collision sampler 02 and focusing nozzle 03 The connecting pipe between them reduces the loss along the process and avoids the problem of clogging, thereby improving the working eff...

Abstract

The invention discloses a sampling and focusing composite nozzle device. The sampling and focusing composite nozzle device comprises an upper end cover, an acceleration nozzle assembly, a closing nozzle assembly and a nozzle base, wherein the upper end cover is used for supplying aerosol fluid into the upper end cover, the acceleration nozzle assembly is attached to the upper end cover and is usedfor accelerating aerosol fluid, the closing nozzle assembly is connected to the acceleration nozzle assembly in a matched mode, and the nozzle base is connected to the closing nozzle assembly and isused for spraying the aerosol fluid; an inlet channel is formed in the upper end cover; a first cavity used for sampling is formed between the acceleration nozzle assembly and the closing nozzle assembly, and a sampling hole is formed in the side wall of the first cavity; and an outlet channel used for spraying the aerosol fluid is formed in the nozzle base, and an air inlet channel used for gathering aerosol fluid to the outlet channel is formed between the closing nozzle assembly and the nozzle base. The invention further discloses aerosol direct-writing printing equipment with the samplingand focusing composite nozzle device. According to the sampling and focusing composite nozzle device, the problem of blocking between a collision sampler and a nozzle is solved, and the working efficiency of the aerosol direct-writing printing equipment is improved.

Description

technical field [0001] The invention relates to the technical field of aerosol direct writing printing, in particular to a sampling focusing compound nozzle device. The present invention also relates to an aerosol direct-writing printing device provided with the above sampling and focusing compound nozzle device. Background technique [0002] Aerosol is a colloidal dispersion system formed by dispersing solid or liquid small particles and suspending them in a gas medium, also known as a gas dispersion system. [0003] Its dispersed phase is solid or liquid small particles with a size of 0.001-100 microns, and its dispersion medium is gas. Liquid aerosols are commonly referred to as fog, and solid aerosols are commonly referred to as smog. The aerosol direct writing printing process is to deposit the aerosol on the substrate orderly in the form of direct writing, such as figure 1 As shown, three basic steps are involved in the process: the atomizer 01 atomizes to generate ...
