Description

Technical Field

[0001] This utility model relates to the technical field of handheld dust collectors, specifically to a blower-suction integrated dust collector, which is particularly suitable for dust collectors where the head assembly and handle assembly can be adjusted at relative angles. Background Technology

[0002] Integrated blower-vacuum dust collectors, combining both blowing and suction functions, are widely used in vehicle cleaning, yard dust removal, and workshop maintenance. For these integrated dust collectors with one blowing end and one suction end, users often need to rotate the working head 180 degrees to operate the machine, which places demands on the comfort of holding the handle during this 180-degree rotation. As users' demands for ease of operation increase, mainstream products are gradually developing towards lightweight design and ergonomic optimization.

[0003] In existing technologies, to meet the requirement of 180-degree rotation of the working head for gripping, the machine can only be designed with a T-shaped body and a cylindrical handle structure, matched with a simple button-type locking switch. This makes it difficult to meet the user's comfortable grip needs, resulting in poor ergonomics. The above problems are particularly prominent when using stroke speed control switches in integrated blowing and suction dust collectors. Utility Model Content

[0004] The purpose of this invention is to provide an integrated blowing and suction dust collector. Addressing the issue of grip comfort when using stroke-adjustable speed switches with a 180-degree handle rotation, this invention rotates the handle assembly 180 degrees relative to the working head, ensuring comfortable grip during both blowing and suction operations. The 180-degree working head rotation structure is reliable and has a long service life.
