AIR INTAKE STRUCTURE AND POWDER TANK

Document Type and Number:

WIPO Patent Application WO/2024/077869

Kind Code:

A1

Abstract:

An air intake structure (200) and a powder tank. The air intake structure comprises: a base (201), which is provided with a first passage (205), a first end of the first passage (205) being in communication with an air delivery pipe (101); and a connecting seat (202), which is provided with a second passage (206), a first end of the second passage (206) being in communication with an air guide pipe of a powder tank, wherein the base (201) is sleeved on the connecting seat (202); an annular gap (207) is formed between the base (201) and the connecting seat (202); and a second end of the first passage (205) is in communication with a second end of the second passage (206) by means of the annular gap (207). The first passage (205) and the second passage (206) of the air intake structure (200) are in communication by means of the annular gap (207), a high-pressure airflow flows through the annular gap (207) from the first passage (205) and then flows into the air guide pipe of the powder tank through the second passage (206), such that the high-pressure airflow can also flow into the second passage (206) without the need to accurately align the first passage (205) with the second passage (206), thereby simplifying the alignment process for air intake passages on the base (201) and the connecting seat (202), and improving the efficiency of assembling the base (201) and the connecting seat (202).
