[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a fixing component. When installing the dust cleaning device, first, a hole is opened on the flue wall, and the hole diameter should match the diameter of the sound waveguide. Then, the bracket is installed outside the flue wall so that the fixing frame is on the hole side. Then, the loudspeaker is installed in the hole so that the end of the loudspeaker is butted against the end of the connecting cavity. Then, the rotating block is rotated.

When the fixing ring fixes the loudspeaker, the buffer pad first contacts the outer wall of the loudspeaker, and in the process of fixing the loudspeaker, the contact of the buffer pad assists the loudspeaker to adjust its position, thereby improving the fixing effect.

[0020] 3. The present invention sets a control component. When the two fixing rings are close to each other, the protrusion is forced to slide into the fixing ring. When the protrusion moves, the control plate rotates. The rotation of the control plate drives the through hole to rotate and coincide with the glue outlet hole, so that the sealant inside the glue storage bag is discharged from the glue outlet hole. This not only helps to improve the stability of the device installation, but also seals the gap between the conduit and the flue wall to prevent smoke leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The fixing assembly includes a fixing ring 6 arranged inside the fixing frame 5, and two fixing rings 6 are symmetrically arranged. The two ends of the fixing ring 6 are respectively embedded with a limiting shaft 7 and a threaded rod 8. The fixing ring 6 is slidingly connected to the limiting shaft 7, and the fixing ring 6 is threadedly connected to the threaded rod 8. A first bevel gear 9 is fixedly installed on the top of the threaded rod 8, and a second bevel gear 10 is meshingly connected to one side of the first bevel gear 9. A rotating shaft 11 is fixedly installed on one side of the second bevel gear 10, and a rotating block 12 is fixedly connected to one end of the rotating shaft 11. The rotating block 12 is arranged on one side of the fixing frame 5.

[0032] Existing: CN207073827U discloses a variable frequency electric sonic sootblower, which discloses the bracket 1, driving device 2, connecting cavity 3 and loudspeaker 4 proposed in this application document, and this technical means will not be described one by one here;

[0033] The connecting cavity 3 is used to connect the resonance cavity and the loudspeaker 4;

[0034] When installing the dust cleaning device, firstly, a hole is made on the flue wall, the hole diameter of which should match the diameter of the acoustic waveguide, and then the bracket 1 is installed outside the flue wall so that the fixing frame 5 is on the side of the hole;

[0035] Then install the loudspeaker 4 in the hole so that the end of the loudspeaker 4 is butted against the end of the connecting cavity 3;

[0036] Then rotate the rotating block 12, the rotation of the rotating block 12 drives the rotation of the rotating shaft 11, the rotation of the rotating shaft 11 drives the rotation of the second bevel gear 10, the rotation of the second bevel gear 10 drives the rotation of the first bevel gear 9, the rotation of the first bevel gear 9 drives the rotation of the threaded rod 8, the rotation of the threaded rod 8 drives the movement of the fixing ring 6, so that the two fixing rings 6 move inward to fix the outer wall of the loudspeaker 4, thereby improving the stability of the device connection to ensure the stable operation effect of the equipment.

[0037] like Figures 1 to 7 As shown, a pressure block 13 is slidably installed inside the fixing ring 6 , a first spring 15 is provided between the fixing ring 6 and the pressure block 13 , and a buffer pad 14 is fixedly installed at one end of the pressure block 13 away from the fixing ring 6 .

[0038] The elastic potential energy of the first spring 15 makes the pressure block 13 always have a tendency to move outward. When the fixing ring 6 fixes the loudspeaker 4, the buffer pad 14 first contacts the outer wall of the loudspeaker 4, and in the process of fixing the loudspeaker 4, the contact of the buffer pad 14 assists the loudspeaker 4 to adjust its position, thereby improving the fixing effect.

[0039] like Figures 1 to 7 As shown, an air bag 16 is fixedly mounted on the inner wall of the fixing ring 6 .

[0040] The side of the airbag 16 away from the fixing ring 6 is tilted, which can better fit the outer wall of the loudspeaker 4 and improve the fit between the fixing ring 6 and the loudspeaker 4.

[0041] like Figures 1 to 7 As shown, a connecting tube 17 is embedded in the interior of the fixing ring 6 , and two ends of the connecting tube 17 are fixedly connected to the airbag 16 and the pressing block 13 respectively.

[0042] The cushion 14 is hollow and contains gas.

[0043] When the cushion 14 contacts the outer wall of the loudspeaker 4, the gas inside the cushion 14 enters the airbag 16 through the connecting tube 17, so that the airbag 16 is inflated, thereby improving the sealing between the fixing ring 6 and the loudspeaker 4 and ensuring the stability of the device during operation.

[0044] like Figures 1 to 7 As shown, a glue storage bag 18 is provided on one side of the fixing ring 6, a bellows 19 is connected between the glue storage bag 18 and the fixing ring 6, glue outlet holes 20 are evenly opened on one side of the fixing ring 6, and a control component is provided inside the fixing ring 6.

[0045] The inner cavity of the rubber storage bag 18, the bellows 19 and the fixing ring 6 are communicated.

[0046] The plastic storage bag 18 is flexible and has sealant pre-placed in it.

[0047] like Figure 5 and Figure 7 As shown, the control assembly includes a control board 21 slidably mounted inside the fixing ring 6 , the inner wall of the control board 21 is evenly provided with through holes 22 , and one end of the control board 21 is fixedly connected with a protrusion 23 .

[0048] When the two fixing rings 6 are close to each other, the protrusion 23 is forced to slide into the fixing ring 6. When the protrusion 23 moves, the control board 21 rotates. The rotation of the control board 21 drives the through hole 22 to rotate and overlap with the glue outlet hole 20, so that the sealant inside the glue storage bag 18 is discharged from the glue outlet hole 20, which not only helps to improve the stability of the device installation, but also seals the gap between the conduit and the flue wall to prevent smoke leakage.

[0049] like Figure 7 As shown, the protrusion 23 is slidably installed inside the fixing ring 6 , and a second spring 24 is installed between the protrusion 23 and the fixing ring 6 .

[0050] like Figures 1 to 4 As shown, a second pressure plate 27 and a first pressure plate 25 are provided at the bottom of both sides of the rubber storage bag 18, a third spring 26 is provided between the two first pressure plates 25 and the second pressure plates 27, and the two first pressure plates 25 and the second pressure plates 27 are respectively installed on the outer walls of the limiting shaft 7 and the threaded rod 8.

[0051] The elastic potential energy of the third spring 26 enables the second pressing plate 27 to always have a force pressing inwards toward the glue storage bag 18, so as to facilitate the discharge of the sealant.

[0052] like Figures 1 to 4 As shown, one of the first pressing plates 25 is threadedly connected to the threaded rod 8 .

[0053] When the fixing ring 6 moves and fixes, it drives the first pressing plate 25 to move, compressing the third spring 26, thereby increasing the pressure on the glue storage bag 18, reducing leakage problems caused by uneven sealant or insufficient adhesion, and extending the service life of the equipment.

[0054] like Figures 1 to 4 As shown, one of the second pressing plates 27 is slidably connected to the threaded rod 8 .

[0055] Working principle and usage process:

[0056] When installing the dust cleaning device, firstly, a hole is made on the flue wall, the hole diameter of which should match the diameter of the acoustic waveguide, and then the bracket 1 is installed outside the flue wall so that the fixing frame 5 is on the side of the hole;

[0057] Then install the loudspeaker 4 in the hole so that the end of the loudspeaker 4 is butted against the end of the connecting cavity 3;

[0058] Then, the rotating block 12 is rotated, and the rotation of the rotating block 12 drives the rotation of the rotating shaft 11, and the rotation of the rotating shaft 11 drives the rotation of the second bevel gear 10, and the rotation of the second bevel gear 10 drives the rotation of the first bevel gear 9, and the rotation of the first bevel gear 9 drives the rotation of the threaded rod 8, and the rotation of the threaded rod 8 drives the movement of the fixing ring 6, so that the two fixing rings 6 move inward to fix the outer wall of the loudspeaker 4;

[0059] At the same time, the movement of the fixing ring 6 drives the first pressing plate 25 to move, compressing the third spring 26 and increasing the pressure on the plastic storage bag 18;

[0060] When the fixing ring 6 fixes the loudspeaker 4, the buffer pad 14 first contacts the outer wall of the loudspeaker 4, and in the process of fixing the loudspeaker 4, the contact of the buffer pad 14 assists the loudspeaker 4 to adjust its position;

[0061] When the cushion 14 contacts the outer wall of the loudspeaker 4, the gas inside the cushion 14 enters the airbag 16 through the connecting pipe 17, so that the airbag 16 is inflated and expanded, so as to fit the outer wall of the loudspeaker 4;

[0062] When the two fixing rings 6 are close to each other and fit together, the protrusion 23 is forced to slide into the fixing ring 6. When the protrusion 23 moves, the control plate 21 rotates. The rotation of the control plate 21 drives the through hole 22 to rotate and overlap with the glue outlet hole 20, so that the sealant inside the glue storage bag 18 is discharged from the glue outlet hole 20 to seal the device.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
