AI Technical Summary
Technical Problem
Existing garment processing equipment is prone to negative pressure during the water intake process due to factors such as damaged water inlet faucets, detached water inlet pipes, or water outages. This can cause the additive water to flow backwards and contaminate the tap water pipes.
Method used
The jetting design includes coaxially arranged ejector and injection ports within the housing, and a gap connecting it to the external atmosphere prevents backflow, ensuring smooth water flow and maintaining pressure.
Benefits of technology
It effectively prevents water backflow, maintains the pressure of the inlet water circuit, avoids tap water contamination, and improves the reliability of the water supply system for clothing processing equipment.

Abstract
一种衣物处理设备用的射流器，其包括，壳体，壳体内设有供水流流经的通道；壳体上具有将流道与外部大气相连通的间隙；壳体的流道内设有处于间隙上游侧的射出孔、和处于间隙下游侧的射入孔，射出孔的中心线与射入孔的中心线同轴设置，射出孔直径近似等于射入孔直径。本发明通过在射流器上设有将流道与外部大气相连通的间隙，间隙可用于将自射流器倒流的水流排出、以实现安装有射流器的水路防倒流的使用目的；同时，通过射流器的壳体的相对两端分别设射入孔和射出孔，令二者孔径等大开设，以实现将喷至射入孔处的水流可尽量覆盖射入孔，令射入孔下游的水路进水端不会敞口设置，进而达到对进水水流保压、避免进水过程中间隙下游水路中的水流因受间隙作用而泄压情况的发生。
