Dust collector

Abstract

This product is a "dust collector" designed to improve environmental hygiene and worker safety at the work site when cleaning and repairing walls, floors, etc. (hereinafter also referred to as "walls, etc.") using a laser device. It efficiently sucks up and collects rust, paint, dust, and other unwanted substances adhering to the wall, etc., when the surface is being cleaned by laser irradiation, thereby removing the removed substances. In particular, it is intended for use in combination with the head of a handheld laser device, and is designed to minimize the scattering of fine dust and particles generated during removal work, enabling efficient and clean operation. This product mainly consists of a hollow, elongated passage tube, a suction body at its tip, and a regulating arm attached near the suction body. The passage tube has a passage space formed inside for transporting collected dust and other materials, and has a structure that allows for extension and retraction adjustment according to the work environment and application. This allows for use at an appropriate length and angle depending on site constraints, worker posture, and the height of the object being cleaned. Furthermore, a suction body is attached to the tip of the passage pipe. This suction body has a hollow cylindrical section and a truncated square pyramidal section. The bottom edge of the truncated square pyramidal section serves as the suction port, which is positioned to face laterally with respect to the longitudinal direction of the passage pipe. This structure allows the dust collector to be moved along a wall or other surface while efficiently sucking up removed particles and dust over a wide area. When in use, a vacuum cleaner hose is connected to the base end of the passage pipe. The suction port of the suction body is kept at a constant distance from the wall or other surface by the regulating arm of the dust collector. The regulating arm consists of a connecting annular section and a pair of legs, with guide rollers rotatably attached to the tips of the legs. These guide rollers are formed in a disc shape. The legs and guide rollers are arranged symmetrically with respect to the axis of the passage pipe, resulting in good weight balance for the entire dust collector and contributing to stability during operation. With this product, users simply need to lightly press the dust collector against a wall or other surface, and the regulating arm will automatically maintain the appropriate dust collection distance, ensuring stable dust collection performance even during prolonged use. This product is distinctive not only for its high dust collection performance but also for its design.The design features a streamlined and efficient silhouette for the passage pipe, a sharp and functional shape for the truncated pyramidal suction body, a balanced stability provided by the pair of legs and guide rollers, and an overall lightweight and compact appearance. This design offers ease of handling and visibility on-site, as well as a modern and functional aesthetic. In addition, attention to detail is evident in the design of the guide rollers and other components, achieving a high level of balance between practicality and design without compromising the overall aesthetics. The dust collector covered by this design includes a "holding frame" for holding and supporting the head of the laser device. However, the shape and structure of this holding frame are excluded from the scope of the design registration (disclaimer). While the holding frame exists as a part of the design, its specific design does not constitute the essential part of this design. The creative features of this design lie in the form and combination of the passage pipe, suction body, and regulating arm section (including legs and guide rollers). Furthermore, while this product is primarily intended for use in laser cleaning operations, it can also be applied to a variety of on-site tasks involving the generation of dust and fine particles, such as paint removal, rust removal, dust removal, and various cleaning and repair work on walls and other industrial surfaces. As a product that significantly contributes to reducing the burden on on-site workers, improving work quality, and ensuring the safety of the work environment, it has the potential to be expanded to a wide range of applications. This product, with its design that pursues both functionality and aesthetics as described above, possesses intuitive operability, efficiency, cleanliness, and an appearance that appeals to a sense of advanced technology, making it a creation of a dust collector that has the potential to become a new standard in modern industrial settings.
