[0021] ​In order to make the purpose, technical scheme of the utility model carry out clearly, complete description, and the advantage is more clear and distinct, the following combining with the drawing to the utility model embodiment carries out further detailed explanation.Should understand, the specific embodiment described here is a part of the embodiment of the utility model, rather than all the embodiment, only use to explain the embodiment of the utility model, and do not use to limit the embodiment of the utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor belong to the scope of protection of the utility model.

[0022] Please refer to Figures 1-5 The utility model provides a technical scheme: a cloth bag replacement structure for cloth bag dust catcher, including fastener, the fastener is located in the inside of dust cloth bag 6, after the inside of dust cloth bag 6 is turned over, fastener is buckled on the limiting ring, the limiting ring is located in the inside of dust cloth bag 6, dust cloth bag 6 is set on the framework;The framework includes framework ring 7 and connecting rod 8, framework ring 7 is equipped with multiple, multiple framework ring 7 is arranged in up-down, connecting rod 8 is fixed in the inner ring surface of multiple framework ring 7, and connecting rod 8 is equipped with multiple, multiple connecting rod 8 is arranged in equal distance along the inner ring surface of framework ring 7. Why dust cloth bag 6 is set on the framework that connecting rod 8 and framework ring 7 constitute is to increase the contact area of dust cloth bag 6 and gas after dust cloth bag 6 is pried open, ensure that dust cloth bag 6 and gas are fully contacted and carry out dust removal operation.

[0023] The fastener is equipped with multiple groups, and each group of fastener is between the adjacent two connecting rods 8, and the top of dust cloth bag 6 is turned over to form a bag inside turning part 5, and the bag inside turning part 5 covers the top of the framework ring 7 and the top of the connecting rod 8;The fastener includes plastic strip 1 and the elastic hoop piece 2 integrally formed on the surface of plastic strip 1, and the plastic strip 1 is in the form of a circular arc plate structure, the outer ring surface of the plastic strip 1 is a circular arc surface, the elastic hoop piece 2 is in the form of a circular arc strip, the elastic hoop piece 2 is provided with two, the two elastic hoop pieces 2 are symmetrically distributed about the plastic strip 1 in up-down, and the circular arc surface of the elastic hoop piece 2 and the circular arc surface of the plastic strip 1 are communicated;The inner ring surface of the elastic hoop piece 2 is fixed with a plurality of rubber strips 3;The limiting ring includes an elastic plastic ring 4, and the elastic plastic ring 4 is fixed to the inner wall of the dust cloth bag 6, and the two elastic hoop pieces 2 are buckled on the elastic plastic ring 4, and the rubber strips 3 are clamped between the elastic hoop piece 2 and the elastic plastic ring 4 to produce elastic deformation. When the dust cloth bag 6 needs to be replaced, the plastic strip 1 is pinched from the bottom end of the bag inside turning part 5, and the plastic strip 1 is stretched with force, the plastic strip 1 pulls the elastic hoop piece 2 away from the elastic plastic ring 4, and after the multiple elastic hoop pieces 2 are removed from the elastic plastic ring 4, the bag inside turning part 5 is turned outwards to the top of the dust cloth bag 6, and then the dust cloth bag 6 is separated from the framework, and a new dust cloth bag 6 is set on the framework, the bag inside turning part 5 is turned inwards, and the plastic strip 1 is pushed and squeezed, so that the elastic hoop piece 2 is buckled on the elastic plastic ring 4, and the dust cloth bag 6 is prevented from being removed and limited.

[0024] The process for replacing the cloth bag of the cloth bag dust collector is as follows:

[0025] Remove the old cloth bag: Observe and confirm the position of the fastener at the bottom end of the bag inner turning part 5, especially the plastic strip 1 and the elastic hoop 2. Pinch the plastic strip 1 from the bottom end of the bag inner turning part 5, and pull the plastic strip 1 with force. The plastic strip 1 pulls the elastic hoop 2 off the elastic plastic ring 4. Note that this process may require moderate force, but care should be taken not to damage the fastener or the cloth bag. Repeat this step until all groups of elastic hoops 2 are removed from the elastic plastic ring 4. Turn the bag inner turning part 5 outside to the top of the dust cloth bag 6, exposing the skeleton.
