Benefits of technology

[0006]It is therefore a primary object of the present invention to provide an improved dust bag structure easily fittable and connectable to a dust collector. The dust bag can be fitted to the collection tube and then directly simultaneously secured to the collection tube. Therefore, it is unnecessary to first preliminarily locate the bag body and then secure the bag body to the collection tube as in the prior art.

Problems solved by technology

Therefore, it is uneasy to fit the bag body onto the collection tube of the dust collector.
This is quite inconvenient.
However, in practice, it is inconvenient to use the resilient plates 2 or spring clips 3.
Obviously, such process is troublesome and inconvenient.

Embodiment Construction

[0018]Please refer to FIGS. 3 to 6. According to a first embodiment, the dust bag structure 10 easily fittable and connectable to a dust collector of the present invention is composed of a dust bag 20 and a retainer member 30.

[0019]In this embodiment, the dust bag 20 is a soft bag-like body made of polyethylene. The dust bag 20 includes a soft bag body 21 having an open end 22 communicating an internal space of the bag body 21 with outer side thereof. The open end 22 is coaxially fitted on a collection tube 40 of a conventional dust collector. A hollow connection section 23 is positioned on outer circumference of the bag body 21 and extends along a periphery of the open end 22 in the form of an arc. In manufacturing, the connection section 23 is formed in such a manner that the original open end of the dust bag 20 is folded over itself with the endmost section fused with the outer circumference of the bag body 21 by means of thermal fusion or ultrasonic fusion. After folded, the new...

Abstract

A dust bag structure easily fittable and connectable to a dust collector. The dust bag structure includes a dust bag and a retainer member. The dust bag includes a soft bag body having an open end. The open end is coaxially fittable and connectable to a collection tube of the dust collector. The retainer member is disposed around a periphery of the open end of the dust bag for fixing the dust bag with the collection tube. The dust bag further includes a connection section positioned at the open end for connecting with the retainer member, whereby the open end is looped with and connected with the retainer member.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to a dust collector, and more particularly to a dust bag structure easily fittable and connectable to a dust collector.[0002]It is known that in a working site, waste powders and dusts are often produced in processing operation and spread in the air. The powders and dusts contained in the air are generally filtered off from the air and collected by means of a dust collector to avoid air pollution. The collected powders and dusts can be recovered for other use. In general, the powders and dusts are collected in a bag body or the like. The bag body has an opening fitted to a collection tube of the dust collector. The opening of the bag body is then looped with a fastening strap assembly and fastened to the collection tube by means of the fastening strap assembly. Accordingly, the bag body can be tightly connected to the collection tube of the dust collector.[0003]However, the conventional bag body is generally a ...
