Description

Technical Field

[0001] This utility model relates to a dust collection device, and more particularly to a dust collector for power tools with a detachable dust collection box. Background Technology

[0002] Dust collectors are typically used in conjunction with handheld drilling tools (such as electric drills, impact drills, and hammer drills) to collect dust and other debris during drilling operations, preventing dust and other debris from accumulating in the work area.

[0003] Existing dust collectors, such as the dust collection device for power tools disclosed in CN102756361B and the power tool itself, include a housing with a protruding suction inlet and capable of being mounted on the power tool; a dust collection line formed in the housing for air drawn in from the suction inlet to pass through; and a dust collection box that is detachably connected to a joint provided in the housing and has a filter inside, with an inlet on the upstream side of the filter and an outlet on the downstream side of the filter, the dust collection box being part of the dust collection line.

[0004] The existing dust collection box for containing sucked-in dust and other debris is detachably connected to a joint on the housing. The dust collection box has an inlet and an outlet, and the joint has a first opening and a second opening that respectively mate with the inlet and the outlet. The first opening communicates with the suction inlet, and the second opening communicates with the external atmosphere. When the dust collection box is installed on the housing, the first opening mates with the inlet to allow dust to enter the dust collection box, and the second opening mates with the outlet to allow air sucked into the dust collection box to be drawn out through the second opening. Because the dust collection box is designed to be detachable, gaps can easily exist between the first opening and the inlet, and between the second opening and the outlet, due to dimensional errors or other reasons. During dust collection, external air can enter through these gaps, causing the suction force to be uneven and affecting the suction effect of the inlet. Furthermore, the gap between the first opening and the dust collection box inlet can easily allow sucked-in dust or other debris to leak out through the gap. Utility Model Content
