Description

Technical Field

[0001] The utility model relates to the technical field of spray guns, in particular to a spray gun with a flow meter. Background Art

[0002] Putty paste is a decorative material for leveling the wall surface. It is a paste-like paint and an essential product before painting. It is applied on the primer or directly on the object to remove the uneven defects on the surface of the object. Putty paste is made by mixing water and raw materials. The amount of water added needs to be strictly controlled. At present, adding water to the raw materials is mainly done by spraying guns. During the water adding process, water is first sprayed into a measuring cylinder and weighed, and then poured into the raw materials for mixing.
