[0039] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0040] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0041] like Figure 1-11 As shown, an anti-clogging bag dust collector comprises: a base frame 1, an annular dust collecting member 2 mounted on the base frame 1, a mounting plate 3 fixedly fitted with the annular inner edge of the dust collecting member 2, a cylindrical shell 4 detachably mounted on the annular outer edge of the dust collecting member 2 at its open end, a filter bag 5 detachably mounted on the mounting plate 3 at its open end through a mounting mechanism, a rotating ring 6 slidably connected to the mounting plate 3 coaxially, a driving mechanism for driving the rotating ring 6 to rotate, a plurality of vertical first dust removal rods 7 evenly distributed along the circumferential direction of the rotating ring 6 and capable of contacting the inner wall of the filter bag 5, and a dust removal unit mounted on the shell 4;

[0042] An air inlet 8 is provided on the top of the shell 4, an exhaust port 9 located on the inner side of the rotating ring 6 is provided on the mounting plate 3, an exhaust fan 10 is mounted on the lower surface of the mounting plate 3, and the dust removal unit includes a rotating frame 11 which is coaxially arranged with the shell 4 and can rotate around its own axis, and a plurality of groups of vertical second dust removal rods 12 which are evenly distributed along the circumferential direction of the rotating frame 11 and can elastically move close to the axis of the rotating frame 11 to abut against the outer wall of the filter bag 5.

[0043] In the above technical solution, the exhaust fan 10 is started to generate negative pressure inside the filter bag 5, so that the external air enters the shell 4 through the air inlet 8, and then passes through the filter bag 5 into the interior thereof, and the filter bag 5 can filter out dust.

[0044] Because the second dust removal rod 12 can move close to the axis of the mounting plate 3, it cooperates with the first dust removal rod 7 to tighten the filter bag 5, so that the ventilation holes on the filter bag 5 can be fully opened, thereby increasing the ventilation volume of the filter bag 5. The ventilation holes of the pleated filter bag 5 cannot be fully opened, thereby affecting the ventilation volume of the filter bag 5.

[0045] The first dust removal rod 7 and the second dust removal rod 12 can tighten the filter bag 5. The first dust removal rod 7 and the second dust removal rod 12 rotate synchronously. The first dust removal rod 7 can scrape off the dust on the surface of the filter bag 5 to avoid clogging of the filter bag 5. The dust will fall downward into the dust collecting part 2, thereby ensuring the air permeability of the filter bag 5, extending the service life of the filter bag 5, and reducing the replacement frequency of the filter bag 5.

[0046] Furthermore, liquid, such as tap water, may be filled in the dust collecting member 2 so that the dust can enter the liquid, thereby preventing the fallen dust from entering the air again.

[0047] In a preferred embodiment of the invention, a center rod 13 is coaxially fixedly mounted on the mounting plate 3, and a positioning member in contact with the inner top wall of the filter bag 5 is fixedly connected to the upper end of the center rod 13;

[0048] The positioning member includes a mounting portion 14 fixedly connected to the center rod 13, an arc-shaped support portion 15 fixedly connected to the mounting portion 14, and a vertical positioning rod portion 16 fixedly installed on the upper surface of the arc-shaped support portion 15. The positioning rod portion 16 is detachably equipped with a clamp mechanism that cooperates with the positioning rod portion 16 to fix and clamp the top of the filter bag 5.

[0049] In the above technical solution, the arc-shaped support portion 15 can reduce the scratches on the filter bag 5 caused by the positioning piece. The top of the filter bag 5 can be fixed by the clamping mechanism and the positioning rod portion 16. When the first dust removal rod 7 and the second dust removal rod 12 rotate, the filter bag 5 can be prevented from twisting, thereby improving the dust scraping effect of the second dust removal rod 12 and the first dust removal rod 7.

[0050] In a preferred embodiment of the invention, the clamp mechanism comprises a first clamp arm 17, a second clamp arm 18 having a hinged portion hinged to the first clamp arm 17 at one end, and a threaded rod 19 hinged to the second clamp arm 18 away from the hinged portion, an end of the first clamp arm 17 away from the hinged portion is penetrated by an open notch groove for the threaded rod 19 to pass through, and a butterfly nut 20 that can abut on the side of the first clamp arm 17 away from the second clamp arm 18 is threadedly connected to the threaded rod 19;

[0051] An arc-shaped groove matching the positioning rod 16 is recessed on one side of the first clamping arm 17 and the second clamping arm 18 that faces each other.

[0052] In the above technical solution, when installing the clamp mechanism, the portion of the filter bag 5 in contact with the positioning rod 16 fits with the positioning rod 16, and the first clamp arm 17 is rotated so that the arc-shaped grooves on the first clamp arm 17 and the second clamp arm 18 fit with the portion of the filter bag 5 on the fitting positioning portion 37, and the threaded rod 19 is turned into the notch groove, and the butterfly nut 20 is continuously tightened so that the first clamp arm 17 and the second clamp arm 18 are tightly pressed on the filter bag 5, thereby fixing the top of the filter bag 5.

[0053] In a preferred embodiment of the invention, the mounting disk 3 is coaxially penetrated with a plurality of arc-shaped through grooves 21 which are evenly distributed in the circumferential direction and can be covered by the swivel 6, and an annular connecting member 22 is slidably provided on the lower surface of the mounting disk 3, and a plurality of protrusions are fixedly protruded on the annular connecting member 22, which pass through corresponding arc-shaped through grooves 21 and are fixedly connected to the swivel 6 in a one-to-one manner, and the annular connecting member 22 is connected to the driving mechanism.

[0054] In the above technical solution, the protrusions enable the swivel 6 and the annular connector 22 to fit the surface of the mounting plate 3 and slide synchronously.

[0055] In a preferred embodiment of the invention, the driving mechanism includes an annular rack 23 coaxially fixedly mounted on an annular connecting member 22, a first motor 24 assembled on the lower surface of the mounting plate 3 through a mounting frame, and a gear fixedly mounted on the output shaft of the first motor 24 and meshing with the annular rack 23.

[0056] In the above technical solution, the first motor 24 drives the gear to rotate, which drives the annular connecting member 22 to rotate through the annular rack 23, and the annular connecting member 22 drives the rotating ring 6 to reciprocate, and the protrusion slides reciprocatingly in the arc-shaped through groove 21.

[0057] In a preferred embodiment of the invention, the upper end of the first dust removal rod 7 is bent toward the axis of the mounting plate 3 to form a first bend 25, and both ends of the second dust removal rod 12 are bent away from the axis of the mounting plate 3 to form a second bend 26.

[0058] In the above technical solution, the first curved portion 25 and the second curved portion 26 can prevent the filter bag 5 from being scratched when the first dust removal rod 7 and the second dust removal rod 12 rotate.

[0059] In a preferred embodiment of the invention, the dust removal unit further comprises a second motor 27 fixedly mounted on the housing 4 and having a vertical output shaft fixedly connected to the rotating frame 11, and a plurality of groups of elastic connection mechanisms connected one-to-one with a plurality of second dust removal rods 12 and all mounted on the rotating frame 11;

[0060] The elastic connection mechanism includes a pair of connecting arms 28 arranged at intervals in the radial direction of the mounting plate 3, an X-shaped deformation frame 29 and a first torsion spring 30 mounted on the X-shaped deformation frame 29 to promote its expansion. The connecting arm 28 close to the axis of the mounting plate 3 is fixedly connected to the second dust removal rod 12, and the other connecting arm 28 is fixedly connected to the rotating frame 11. The two upper ends of the X-shaped deformation frame 29 are hinged with hinge bolts, and a pair of hinge bolts are respectively vertically slidably connected to a pair of connecting arms 28, and the two lower ends of the X-shaped deformation frame 29 are respectively hinged to a pair of connecting arms 28.

[0061] In the above technical solution, the second motor 27 drives the rotating frame 11 to rotate reciprocatingly, thereby driving the second dust removal rod 12 to rotate reciprocatingly to scrape off the dust on the outer wall of the filter bag 5; the second torsion spring 41 can push the X-shaped deformation frame 29 to unfold, so that the distance between a pair of connecting arms 28 increases, thereby driving the second dust removal rod 12 to move close to the axis of the mounting plate 3 to contact the outer wall of the filter bag 5, and cooperate with the first dust removal rod 7 to tighten the filter bag 5.

[0062] Due to manufacturing errors in the manufacturing process, different filter bags 5 are different, and the spacing between a pair of connecting arms 28 can be automatically adjusted according to the specifications of the filter bag 5, so that the second dust removal rod 12 can tightly contact the outer wall of the filter bag 5.

[0063] In a preferred embodiment of the invention, the mounting mechanism includes an annular seat 31 which is coaxially fixedly connected to the mounting plate 3 and has an annular groove recessed on its upper surface, a pressing ring 33 which is coaxially arranged with the annular seat 31 and has a first annular flange 32 protruding therefrom which can be inserted downward into the annular groove to press the edge of the filter bag 5, and a plurality of mounting bolts 34 which vertically pass through the pressing ring 33 and are threadedly connected to the annular seat 31.

[0064] In the above technical solution, after the filter bag 5 is sleeved on a plurality of first dust removal rods 7, the edge of the open end of the filter bag 5 is pressed into the annular groove, and the first annular flange 32 is inserted into the annular groove. Then, by screwing the mounting bolts 34 into the annular seat 31, the first annular flange 32 is tightly pressed against the edge of the open end of the filter bag 5.

[0065] In a preferred embodiment of the invention, a tubular member 35 is coaxially fitted and fixedly connected to the outer edge of the dust collecting member 2, a second annular flange 36 is coaxially protruded from the outer wall of the tubular member 35, at least one vertical positioning portion 37 located above the second annular flange 36 is protruded from the outer wall of the tubular member 35, and a positioning groove matching the positioning portion 37 is recessed at the lower end of the inner wall of the shell 4;

The upper end of the clamping arm 40 is protrudingly provided with an inclined wedge portion that can press on the upper surface of the third annular flange 38, and the hinge seat 39 is equipped with a second torsion spring 41 for driving the clamping arm 40 to rotate.

[0067] In the above technical solution, the positioning portion 37 and the positioning groove function to prevent the shell 4 from rotating. The inclined wedge portion on the clamp arm 40 can be pressed on the top of the third annular flange 38, so that the shell 4 is assembled on the tubular member 35; when the shell 4 needs to be disassembled, the lower end of the clamp arm 40 is pressed, and the clamp arm 40 rotates to drive the inclined wedge portion to rotate away from the shell 4, and the shell 4 can slide upward and separate from the tubular member 35.

[0068] In a preferred embodiment of the invention, a connection port is provided at the lowest point of the dust collecting member 2, and a screw cap 42 is screwed onto the connection port.

[0069] In the above technical solution, the dust on the outer wall of the filter bag 5 will fall into the dust collecting part 2. Some liquid, such as tap water, can be filled in the dust collecting part 2 to prevent the fallen dust from mixing into the air again. After the rotary cover 42 is removed, the mixture can be discharged from the connecting port. During cleaning, the sewage can also be discharged in time through the connecting port, which is also beneficial to the cleaning of the dust collecting part 2.
