Benefits of technology

"The invention is a negative pressure table-top dust collecting machine that includes a machine box, an operation faceplate with wind-sucking vents, a fixing base, a dust-collecting unit with bags, and a blower installed inside the machine box. When the blower is running, air is pumped out of the machine box, creating negative pressure and a vacuum suction force through the wind-sucking vents and the fixing base to collect dust during processing. The blower and dust-collecting unit are installed inside the machine box, eliminating the need for additional pipes and making it more compact, space-efficient, and easy to move around."

Problems solved by technology

However, the dust-collecting unit of the conventional tabletop dust-collecting machine is exposed outside, large in volume and taking much space.
In addition, wind-sucking pipes have to be additionally disposed between the blower and the machine table as well as the wind cover, and the bottom base has to be provided for assembling the blower and the wind cover thereon, thus complicating the structure, increasing producing cost and inconvenient to be moved around.

Abstract

A negative pressure table-top dust collecting machine includes a machine box formed with an interior space, an operation faceplate assembled on the machine box and bored with numerous wind-sucking vents, a fixing base disposed in the interior space of the machine box, a dust collecting unit fitted with the fixing base and provided with dust collecting bags, and a blower positioned in the interior space of the machine box. When the blower is started to operate, the air in the interior of the machine box is pumped out of the machine box, letting the interior of the machine box produce negative pressure. Simultaneously, through the dust collecting bags and the fixing base, each wind-sucking vent of the operation faceplate will produce a vacuum suction force to suck the dust produced during processing into the dust collecting bags to be gathered.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a negative pressure tabletop dust-collecting machine, particularly to one taking less space and convenient to be moved around. [0003] 2. Description of the Prior Art [0004] A conventional tabletop dust-collecting machine includes a support frame having its topside assembled with a machine table provided thereon with a work faceplate with wind-sucking vents. The machine table is connected with a wind-sucking pipe connected with a dust-collecting unit, which is composed of a blower connected with the wind-sucking pipe, a wind cover connected with the blower, a dust-collecting bag assembled with the wind cover and a bottom base for assembling the blower and wind cover thereon. When the blower is started to operate, each wind-sucking vent of the work faceplate will produce a vacuum suction force through the wind-sucking pipe and the machine table for sucking in the dust produced during processi...
