Description

Technical Field

[0001] This utility model relates to the field of liquid spray gun technology, specifically to a hydraulic nozzle and spray gun. Background Technology

[0002] In the food processing industry, oil spraying is a common process aimed at providing a uniform coating to the surface of food ingredients. In existing technology, hydraulic nozzles used for this type of operation typically consist of several parts, including a nozzle body, an internal core, and seals. Their operation generally involves the liquid material flowing through internal channels and being directly atomized or sprayed out in a beam through orifices at the nozzle tip.

[0003] However, existing nozzle structures of this type have some inherent drawbacks. First, due to deficiencies in the design of the internal flow channel structure or pressurization method, the flow path of the liquid before spraying may not be smooth enough, easily leading to turbulence or pressure loss. This results in a dispersed liquid jet and uneven impact force, affecting the uniformity and stability of the coating formed on the food surface. Second, the multi-component structure not only increases production and assembly costs, but the complexity of its internal connections may also lead to loosening due to vibration or liquid erosion during long-term use, resulting in leakage or performance degradation, and requiring relatively high maintenance frequency. Therefore, there is an urgent need for a new nozzle design with a simpler structure that can effectively improve the concentration and stability of the spray. Utility Model Content
