AI Technical Summary

Technical Problem

Existing air knife blowers have blind spots when cleaning components with complex contours or recessed structures, and multiple air knives with independent air supply cause airflow interference and high energy consumption.

Method used

Design a cross-type air knife water blower, which is divided into upper and lower symmetrical air guide sections by the main body, with the fluid gaps set at an angle to form a cross-type air knife, so as to realize synchronous air supply from a single air source, and connect to the gas flow channel through the air guide pipe to ensure consistent gas pressure and flow rate.

Benefits of technology

It effectively covers the upper and lower surfaces and corners of components, improving cleaning efficiency, avoiding airflow interference, reducing energy consumption, and improving airflow stability.

Abstract

This utility model relates to the field of water blower technology, and more particularly to a cross-type air knife water blower. The cross-type air knife water blower includes a fixed bracket and a main body fixedly mounted on the fixed bracket. A passageway cavity is formed in the middle of the main body, dividing it into upper and lower air guide sections. The cross-type air knife water blower provided by this utility model forms a cross-type air knife by having fluid gaps on the two air guide sections arranged at an angle. High-speed airflow is sprayed crosswise from both upper and lower directions, which can fully cover the upper and lower surfaces and corners of the components passing through the passageway cavity, effectively eliminating the dead zones of traditional single-direction air knives, significantly improving cleaning efficiency. Furthermore, the air guide pipe is connected to the gas flow channels of the two air guide sections, enabling a single air source to simultaneously supply air to the upper and lower air guide sections. This design ensures consistent gas pressure and flow rate in the upper and lower fluid gaps, avoiding airflow interference problems from multiple independent air knives, and resulting in stronger airflow stability.
