[0025] 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.

[0026] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] like Figure 1-5 As shown, a deodorizing purifier filter element replacement assembly comprises: a vent pipe 1 with an operation window provided on the side wall, a cover plate 2 detachably mounted on the operation window, a mounting tube 4 fitted and fixedly mounted on the inner wall of the vent pipe 1 and having a closing flange 3 provided on the inner wall, a filter plate 5 detachably mounted on the top side of the closing flange 3 through a mounting mechanism, and a closing unit mounted on the bottom side of the closing flange 3;

[0028] The closing unit includes a plurality of rotating plates 6 which are arranged at equal intervals along the width direction of the closing flange 3 and are installed on the closing flange 3 through a hinge axis whose length direction is consistent with the length direction of the closing flange 3, and an adjusting mechanism assembled on the ventilation pipe 1 and capable of driving the plurality of rotating plates 6 to rotate synchronously around the corresponding hinge axis to fit the closing flange 3. A first arc portion 7 which is coaxial with the hinge axis and tangent to the closing flange 3 is provided on the side of the rotating plate 6 close to the hinge axis, and a second arc portion 8 which can rotate to be tangent to the first arc portion 7 of the adjacent rotating plate 6 is provided on the side of the rotating plate 6 away from the hinge axis.

[0029] The filter plate 5 is an existing mature technology, and commonly used materials include synthetic fiber filter cotton, non-woven fabric, activated carbon filter cotton, etc.

[0030] When the filter plate 5 needs to be replaced, the several rotating plates 6 are first driven to rotate through the adjustment mechanism so that the several rotating plates 6 are in contact with the bottom side of the closed flange 3. When the several rotating plates 6 are in contact with the closed flange 3, the second arc-shaped portion 8 will be tangent to the first arc-shaped portion 7 of the adjacent rotating plates 6, and the several rotating plates 6 will block the closed flange 3. When the filter plate 5 is replaced, the dust accumulated on the filter plate 5 will fall downward. The function of the rotating plate 6 is to catch the dust dropped during the disassembly of the filter plate 5. After the filter plate 5 is removed, the dust on the upper surface of the rotating plate 6 is cleaned. After the cleaning is completed, a new filter plate 5 is installed to avoid secondary pollution caused by the dust falling during the replacement.

[0031] The first arc portion 7 and the second arc portion 8 are tangent to each other and can seal the space between two adjacent rotating plates 6 , thereby preventing accumulated dust from falling from between the two adjacent rotating plates 6 .

[0032] After the filter plate 5 is replaced, the rotating plate 6 is driven to rotate by the adjusting mechanism so that the second arc portion 8 rotates away from the closing flange 3 . At this time, the first arc portions 7 on the rotating plates 6 can support the filter plate 5 .

[0033] The adjustment mechanism includes a first guide sleeve 9 whose length direction is consistent with the width direction of the closing flange 3 and is fixedly installed on the inner wall of the ventilation pipe 1 and is located on the side of the closing flange 3 away from the filter plate 5, a sliding arm 10 that is slidably inserted into the first guide sleeve 9 in the same length direction, a connecting component assembled on the sliding arm 10 and connected to a plurality of rotating plates 6, a connecting sleeve 11 that is arranged in the same length direction as the sliding arm 10 and is fixedly connected to the end of the sliding arm 10 away from the first guide sleeve 9 and slides through the side wall of the ventilation pipe 1, and an adjusting bolt 12 that is assembled on the outer wall of the ventilation pipe 1 through the mounting component and is threadedly connected to the inner wall of the connecting sleeve 11.

[0034] By rotating the adjusting bolt 12, the connecting sleeve 11 can be driven to slide on the side wall of the vent pipe 1, and the connecting sleeve 11 drives the sliding arm 10 to slide in the first guide sleeve 9, and the sliding arm 10 drives the plurality of rotating plates 6 to rotate through the connecting member.

[0035] A mounting ring 13 is fixedly mounted on the end of the connecting sleeve 11 passing through the ventilation pipe 1, and a second guide sleeve 14 for the connecting sleeve 11 to slide through is mounted on the outer side of the ventilation pipe 1, and a rubber pad 15 that can fit and abut against the end of the second guide sleeve 14 is provided on the side of the mounting ring 13 close to the second guide sleeve 14.

[0036] When the filter plate 5 is replaced, the adjusting bolt 12 is rotated to drive the connecting sleeve 11 to slide close to the first guide sleeve 9. The connecting sleeve 11 will drive the mounting ring 13 to move close to the second guide sleeve 14, so that the rubber pad 15 fits and contacts the second guide sleeve 14. The rubber pad 15 can seal the gap between the mounting ring 13 and the second guide sleeve 14 to prevent gas leakage inside the ventilation pipe 1.

[0037] The connecting component includes at least one third guide sleeve 16 fixedly mounted on the sliding arm 10, a connecting arm 17 arranged parallel to the sliding arm 10, and a plurality of connecting rods 18 arranged at intervals along the length direction of the connecting arm 17 and fixedly connected to the connecting arm 17. A guide arm 19 whose length direction is perpendicular to the length direction of the connecting arm 17 and fixedly connected to the connecting arm 17 is slidably inserted on each third guide sleeve 16. The length direction of the guide sleeve is perpendicular to the length direction of the hinge shaft, and the end of each connecting rod 18 away from the connecting arm 17 is hinged to the corresponding rotating plate 6 respectively.

[0038] When the sliding arm 10 slides on the second guide sleeve 14, the guide arm 19 will be driven to move along the length direction of the sliding arm 10 through the third guide sleeve 16. The guide arm 19 will drive the connecting arm 17 to move, and the connecting arm 17 will drive several connecting rods 18 to move. Because the movement of the connecting rod 18 will drive the corresponding rotating plate 6 to rotate, the distance between the connecting rod 18 and the sliding arm 10 will change, which will drive the guide arm 19 to slide on the third guide sleeve 16.

[0039] The mounting component includes a mounting frame 20 fixedly mounted on the outer wall of the vent pipe 1 and an axle seat 21 fixedly mounted on the mounting frame 20 , and the adjusting bolt 12 is coaxially assembled on the axle seat 21 .

[0040] The mounting mechanism includes a plurality of threaded seats 22 arranged on the closing flange 3 , a mounting frame 23 that can be pressed on the top side of the filter plate 5 , and a plurality of mounting bolts 24 that pass through the mounting frame 23 and are connected to the corresponding threaded seats 22 .

[0041] When the filter plate 5 needs to be replaced, the mounting bolts 24 are loosened and removed, and the filter plate 5 can be removed. A new filter plate 5 is placed above the closed flange 3, and the mounting frame 23 is pressed onto the filter plate 5. The mounting frame 23 is then fixed to the closed flange 3 by the mounting bolts 24. The closed flange 3 and the mounting frame 23 can then tightly clamp the filter plate 5.

[0042] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.
