[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By rotating the two fan rings to close or unfold them, the dust bag can be fixed or removed from the output sleeve. The operation is simple and it is more convenient to remove or fix the dust bag.

[0015] 2. By closing the two fan rings together, the second convex ring will be stuck between the first convex rings, thereby squeezing and fixing the dust bag on the outer wall of the output sleeve. At the same time, the convex thorns are inserted into the inside of the limiting sleeve ring, which can effectively prevent the dust bag from slipping off between the output sleeve and the limiting sleeve after being stressed.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 The utility model provides a technical solution: a dust bag installation structure, including a dust bag 1, a limited position ring 101 is embedded and installed on the dust bag 1, and also includes:

[0023] The output sleeve 2 has three first convex rings 202 fixedly installed on the outer wall of the output sleeve 2 at equal intervals, and a convex thorn 203 is fixedly connected to the outer wall of the output sleeve 2 and located below the first convex ring 202;

[0024] The limiting sleeve 3 includes two sector rings 301 , and two second convex rings 302 are fixedly installed on the inner wall of the sector ring 301 at equal distances, and the second convex rings 302 cooperate with the first convex ring 202 .

[0025] In this embodiment, the fan ring 301 is expanded to both sides. Figure 3 As shown, after the dust bag 1 is put on the output sleeve 2, the two fan rings 301 are closed again to form a limiting sleeve 3. At this time, the second convex ring 302 will engage between the first convex rings 202, thereby fixing the dust bag 1 on the outer wall of the output sleeve 2. At the same time, the thorns 203 cooperate with the limiting ring 101, and the thorns 203 are stuck in the limiting ring 101, so that the dust bag 1 can be fixed on the output sleeve 2, thereby conveniently fixing the dust bag 1 on the output sleeve 2.

[0026] Among them, in order to achieve the purpose of rotatably installing the fan ring 301 on the output sleeve 2, the present device adopts the following technical solution: a flange 201 is fixedly connected to the upper edge of the output sleeve 2, a connecting shaft 204 is fixedly installed at the back of the output sleeve 2, and a hinged foot is fixedly installed at a position near the edge of the outer wall of the fan ring 301, and the hinged foot is rotatably matched with the connecting shaft 204.

[0027] The flange 201 can be connected to the inner pipe of the dust collector, and the connecting shaft 204 cooperates with the hinged foot to rotatably install the fan ring 301 on the output sleeve 2, so that the fan ring 301 can rotate on both sides.

[0028] Among them, in order to achieve the purpose of fixing the two fan rings 301 together, the present device adopts the following technical solution: a fixing foot 303 is fixedly installed on the outer wall of the fan ring 301 near the edge of the other side, a fixing bolt 305 is arranged inside the fixing foot 303, and a handle 304 is fixedly installed on the outer wall of the fan ring 301.

[0029] The two fixing legs 303 can be fixed together by the fixing bolts 305, so that the two fan rings 301 are closed and fixed together, so that the fan rings 301 form a limiting sleeve 3, and the fan rings 301 can be driven to move and rotate by using the handle 304.

[0030] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, the fan ring 301 is unfolded to both sides, and then the dust bag 1 is put on the output sleeve 2, and the thorn 203 is inserted into the inside of the limiting sleeve 101, and then the handle 304 is used to drive the fan ring 301 to close, and the two fixing feet 303 are fixed together with the fixing bolts 305, so that the dust bag 1 can be fixed on the output sleeve 2. After unscrewing the fixing bolts 305, the restriction on the two fan rings 301 can be released, and the fan ring 301 can be rotated to both sides to directly remove the dust bag 1.
