Title:
DUAL-FLOW-PATH STRUCTURE AND SPRAY GUN
Document Type and Number:
WIPO Patent Application WO/2022/042710
Kind Code:
A1
Abstract:
Disclosed is a dual-flow-path structure, comprising a gas inlet channel of a gun body and a gas outlet arranged at a front end of the gun body. The gas outlet comprises a first outlet (1) and a second outlet (2) which are isolated from each other. The gas inlet channel is divided by an isolation structure along the axial direction of the gas inlet channel into a first gas inlet channel (6) and a second gas inlet channel (7) isolated from each other, the first gas inlet channel (6) and the second gas inlet channel (7) are each communicated with a gas inlet (32) of the gas inlet channel, the first gas inlet channel (6) is communicated with the first outlet (1) to form a first flow path, the second gas inlet channel (7) is communicated with the second outlet (2) to form a second flow path, and a valve is arranged on the first flow path. The present invention has the advantages that: the mutual influence between two paths of gas flows can be reduced; in addition, the adjustment of the gas spray volume does not need to rely on the gas introducing volume of the other path and the arrangement of the valve is relatively flexible, facilitating the design of gas flow paths. Further provided is a spray gun using the dual-flow-path structure.
