TECHNICAL FIELD

[0001] The present application relates to the technical field of dust collectors, in particular to a combined dust collector metal pipe. BACKGROUND

[0002] A dust collector is a household appliance that uses forced air flow principles to suck dust, dirt and other substances into a dust bag or dust bucket.

[0003] A dust collector pipe connecting device is disclosed in Chinese Patent No. CN222217759U, which includes a connecting assembly and a pipe. The pipe is detachably connected to the dust collector body through the connecting assembly. The end of the pipe away from the connecting assembly is fixedly connected to a handle.

The corrugated pipe is deformed to reduce the length occupied by the dust collecting pipe during packaging. However, when multiple dust collecting pipes are assembled and used, the bending assembly can change the included angle between the axis of the primary pipe and the axis of the secondary pipe, so that the dust collector can adapt to the cleaning work in low space such as the bottom of the bed.

[0019] Optionally, the bending assembly comprises an outer disc arranged on the primary pipe, the secondary pipe is provided with an inner disc coaxial with the outer disc, the outer disc is rotationally connected with the inner disc, the inner disc is uniformly provided with a plurality of angle teeth along the axis thereof in the circumferential direction, the outer disc is slidably provided with an angle pin, the axis of the angle pin is parallel to the axis of the outer disc, the outer disc is provided with a pin slot for the sliding of the angle pin, and an angle compression spring is arranged between the angle pin and the pin slot of the outer disc, and the angle compression spring is used to press the angle pin tightly between two adjacent angle teeth.

[0020] By adopting the technical scheme, the user rotates the primary pipe, the primary pipe drives the outer disc to rotate around the axis of the inner disc, in this process, the angle pin overcomes the resistance of the angle teeth, continuously reciprocatingly compresses and releases the angle compression spring, so that the angle pin continuously emits the sound of click in the process of collision with the angle teeth, when the user stops rotating the primary pipe, the angle pin is clamped between two adjacent angle teeth and achieves the angle fixing effect between the primary pipe and the secondary pipe.

[0024] 1. The worker disassembles a plurality of dust collection pipes on the dust collector, changes the angle between the primary pipe axis and the secondary pipe axis through the bending assembly, and deforms the bellows, thereby reducing the length occupied by the dust collection pipe during packaging. However, when the plurality of dust collection pipes are assembled for use, the bending assembly can change the angle between the primary pipe axis and the secondary pipe axis, so that the dust collector can adapt to the cleaning work in low space such as the bottom of a bed;

[0025] 2. When the connecting concave end on one dust collection pipe is inserted into the connecting convex end on another dust collection pipe, the anti-disengagement block on the connecting convex end abuts against the guide slope on the locking hook block.

At this time, the locking compression spring restores the deformation, thereby achieving the effect of splicing and lengthening.

[0026] 3.
