Detailed Implementation

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1:

[0038] Please see Figures 1-4As shown, this invention is a dust control device for indoor decoration, including a treatment box 1. The interior of the treatment box 1, from top to bottom, comprises an air outlet chamber 101, an air inlet chamber 102, a receiving chamber 103, and a dust collection chamber 104. The air outlet chamber 101 and the receiving chamber 103 are connected by a pair of air conveying channels 105, which are respectively located on opposite sides of the air inlet chamber 102. Multiple sets of filter bags 2, each with open top and bottom ends, are arranged vertically side-by-side within the receiving chamber 103. These filter bags 2 are conventional components in the art, and each set of filter bags 2 has a support ring bolted to both its upper and lower ends. The support rings at the upper ends of the multiple sets of filter bags 2 penetrate and are bolted to the bottom wall of the air inlet chamber 102. The upper part of the dust collection chamber 104 has multiple filter bags 2, and the support rings at the lower ends of the filter bags 2 are all bolted to the bottom wall of the dust collection chamber 104. The exhaust chamber 101 is vertically equipped with a first lifting mechanism 3. The first lifting mechanism 3 is equipped with a second lifting mechanism 4. The second lifting mechanism 4 is located in the air inlet chamber 102. The lower part of the second lifting mechanism 4 is horizontally connected with multiple scraper discs 5. The first lifting mechanism 3 and the second lifting mechanism 4 drive the multiple scraper discs 5 to move downward. The multiple scraper discs 5 can be inserted into the multiple filter bags 2 respectively. Any scraper disc 5 can scrape the dust on the inner wall of the corresponding filter bag 2 into the dust collection chamber 104. The dust collection chamber 104 is equipped with a sealing mechanism 6. The sealing mechanism 6 can seal the lower port of the multiple filter bags 2. In use, indoor air is introduced into the air inlet chamber 102. The air in the air inlet chamber 102 then enters the multiple sets of filter bags 2 from the upper port. After being filtered by the multiple sets of filter bags 2, the air enters the receiving chamber 103. Then, the filtered air flows from the receiving chamber 103 to the air outlet chamber 101 through the air delivery channel 105 and is discharged into the room. This effectively filters the indoor air and improves the efficiency of indoor dust control during decoration. When the inner wall of the filter bag 2 is covered with dust and the filtration effect is poor, the introduction of indoor air into the air inlet chamber 102 is paused. Then, the first lifting mechanism 3 and the second lifting mechanism 4 drive the multiple sets of scraper discs 5 to move downward, causing the multiple sets of scraper discs 5 to be inserted into the multiple sets of filter bags 2 respectively. The edges of the scraper discs 5 clean the dust on the inner wall of the filter bag 2. Dust is scraped downwards. After the scraper 5 contacts the sealing mechanism 6, it continues to move downwards, causing the sealing mechanism 6 to release the seal on the lower port of the filter bag 2, thus allowing the scraped dust to be discharged into the dust collection chamber 104. Then, the first lifting mechanism 3 and the second lifting mechanism 4 drive multiple sets of scraper 5 upwards to their reset position. After the scraper 5 disengages from the sealing mechanism 6, the sealing mechanism 6 re-seals the lower port of the multiple sets of filter bags 2. Then, indoor air can continue to be introduced into the air inlet chamber 102. This not only effectively ensures the treatment of indoor dust during decoration, but also ensures the filtration efficiency and effect of dust. In addition, by designing the first lifting mechanism 3 and the second lifting mechanism 4 to drive the scraper 5 downwards in two stages, the volume of the entire device can be reduced, and the structural compactness of the entire device can be ensured.

[0039] Among them, such as Figures 2-6 As shown, the interior of the treatment box 1 is horizontally arranged side-by-side from top to bottom with a first partition 106, a second partition 107, and a third partition 108. A pair of opposite edges of the first partition 106 and the second partition 107 are respectively connected by vertically arranged fourth partitions 109, and the upper and lower edges of the fourth partitions 109 are welded to the first partition 106 and the second partition 107 respectively. The other opposite edges of the first partition 106, the other opposite edges of the second partition 107, the four edges of the third partition 108, and the opposite sides of the two fourth partitions 109 are all welded to the inner wall of the treatment box 1. An air outlet chamber 101 is formed between the first partition 106 and the top and side walls of the treatment box 1. An air inlet chamber 102 is formed between the first partition 106, the second partition 107, the two fourth partitions 109, and the side walls of the treatment box 1. The second partition 107, the third partition 108, and the... A receiving chamber 103 is formed between the side walls of the treatment box 1; a dust collection chamber 104 is formed between the third partition 108 and the bottom and side walls of the treatment box 1; two air supply channels 105 are formed between the two fourth partitions 109 and the side walls of the treatment box 1; a pair of air outlets 110 are provided side by side on the top wall of the treatment box 1; a conventional first fan 7 in the art is horizontally bolted into each of the two air outlets 110; the air inlet of the first fan 7 faces away from the treatment box 1. The processing chamber 1 has air inlets 111 on opposite side walls that communicate with the air inlet chamber 102. A conventional second fan 8 is vertically bolted into each of the two air inlets 111. The air inlet end of the second fan 8 is facing downward. A dust discharge port 115 is provided at the bottom of one side wall of the dust collection chamber 104. A baffle 116 is vertically provided at the outlet end of the dust discharge port 115. The upper edge of the baffle 116 is rotatably connected to the outlet end of the dust discharge port 115. In use, the first fan 7 introduces indoor air into the air inlet chamber 102, and after the filtered air flows into the air outlet chamber 101, the second fan 8 discharges the air from the air outlet chamber 101 back into the room, effectively ensuring the filtration efficiency of the indoor air. In addition, when the dust in the dust collection chamber 104 accumulates to a certain amount, the dust in the dust collection chamber 104 is cleaned out from the dust outlet 115 by first flipping the baffle 116, effectively ensuring the overall performance of the device.

[0040] Example 2:

[0041] Based on Example 1, as follows Figures 3-4 and Figures 7-12As shown, the first lifting mechanism 3 includes a pair of electric push rods 301 that are respectively vertically bolted to the opposite side walls of the air outlet chamber 101; the output ends of both electric push rods 301 slide through the bottom wall of the air outlet chamber 101 and extend into the air inlet chamber 102, and the output ends of the two electric push rods 301 are connected by a horizontally arranged transmission plate 302; the transmission plate 302 is bolted to the output ends of the electric push rods 301; the four edges of the transmission plate 302 slide against the inner wall of the air inlet chamber 102; The second lifting mechanism 4 includes multiple sets of threaded sleeves 401 arranged side-by-side and vertically inserted on the transmission plate 302, and multiple sets of bearing sleeves 402 arranged side-by-side and vertically inserted on the transmission plate 302; all sets of threaded sleeves 401 are rotatably connected to the transmission plate 302; each set of threaded sleeves 401 has a threaded screw 403 inside; each set of bearing sleeves 402 has a slidingly inserted movable shaft 404 inside; all sets of movable shafts 404 are conventional spline shafts in the art; the lower ends of the sets of movable shafts 404 and the lower ends of the sets of screws 403 are respectively connected by multiple The positioning blocks 405 are connected together; the lower ends of multiple sets of screws 403 are bolted to the positioning blocks 405 respectively; multiple sets of scraper discs 5 are respectively connected to the positioning blocks 405; multiple sets of bearing sleeves 402 are rotatably connected to the transmission plate 302, and any bearing sleeve 402 can drive the movable shaft 404 on it to rotate; the lower ends of multiple sets of movable shafts 404 are rotatably connected to the positioning blocks 405 respectively; a first rotating shaft 406 is vertically rotatably connected to each of the positioning blocks 405; multiple sets of scraper discs 5 are coaxially screwed together. A bolt is attached to the lower end of multiple sets of first rotating shafts 406; a first gear 407 is keyed to the upper end of each set of first rotating shafts 406; a second gear 408 meshes with each set of first gears 407; multiple sets of second gears 408 are keyed to the lower end of multiple sets of movable shafts 404; a third gear 409 is keyed to the outer periphery of multiple sets of bearing sleeves 402; a fourth gear 410 meshes with each set of third gears 409; and multiple sets of fourth gears 410 are keyed to the outer periphery of multiple sets of threaded sleeves 401.In use, the electric push rod 301 first drives the transmission plate 302 downward, causing the second lifting mechanism 4 to move the scraper 5 downward to the upper end of the filter bag 2. Then, by rotating the screw sleeve 401, the screw 403 is driven downward, causing the screw 403 to move downward through the positioning block 405 and the first rotating shaft 406, thus moving the scraper 5 downward to the inner wall of the filter bag 2. During the downward movement of the scraper 5 inside the filter bag 2, the edge of the scraper 5 slides against the inner wall of the filter bag 2, effectively scraping away the dust adhering to the inner wall of the filter bag 2. This ensures the dust removal effect of the filter bag 2 and extends its service life. In addition, during the rotation of the screw sleeve 401, the screw sleeve 401 drives the bearing sleeve 402 to rotate synchronously via the fourth gear 410 and the third gear 409, causing the movable shaft 404 to rotate synchronously with the bearing sleeve 402 during its downward movement. The movable shaft 404 then drives the scraper 5 to rotate inside the filter bag 2 via the second gear 408, the first gear 407 and the first rotating shaft 406, further improving the scraping effect of the scraper 5 on the dust on the inner wall of the filter bag 2.

[0042] Among them, such as Figure 2 , Figures 8-10 and Figure 14 As shown, a drive mechanism 9 is connected to the second lifting mechanism 4; the drive mechanism 9 includes two sets of second rotating shafts 901 vertically rotatably connected to opposite edges of the transmission plate 302, and multiple sets of first pulleys 902 keyed to the outer periphery of multiple sets of threaded sleeves 401; each of the multiple sets of second rotating shafts 901 is keyed from top to bottom with a second pulley 903 and a third pulley 904; each of the opposite sides of any first pulley 902 is vertically rotatably connected to a first tensioning pulley; each set of first pulleys 902 is connected to two corresponding second pulleys 903 and 904 located on opposite edges of the transmission plate 302. The pulleys 903 are connected by a synchronous belt drive, and the first tensioning pulley abuts against the outer surface of the synchronous belt; the third pulley 904, located in the middle, has a second tensioning pulley vertically rotatably connected to both sides on its opposite sides; any set of third pulleys 904 are connected by a synchronous belt drive, and the second tensioning pulley abuts against the outer surface of the synchronous belt; the lower end of any one of the two sets of second rotating shafts 901 is coaxially fixed to the output shaft of a pair of drive motors 905; both drive motors 905 are vertically bolted to the lower surface of the transmission plate 302. In use, the drive motors 905 drive multiple sets of threaded sleeves 401 to rotate synchronously via the second rotating shafts 901, third pulleys 904, second pulleys 903, and first pulleys 902, thereby achieving synchronous lifting and lowering of multiple sets of scraper discs 5 and ensuring the synchronicity of the dust removal operation of multiple sets of filter bags 2.

[0043] In addition, such as Figures 2-6As shown, the upper surface of the first partition 106 has multiple sets of first through holes 112 and multiple sets of second through holes 113 arranged side by side; the upper ends of multiple sets of screws 403 can be respectively fitted into the multiple sets of first through holes 112; the upper ends of multiple sets of movable shafts 404 can be respectively fitted into the multiple sets of second through holes 113; the other opposite edge of the second partition has a recessed folded edge 114 with an L-shaped structure; the two drive motors 905 can move to the inner side of the two recessed folded edges 114 respectively. By opening multiple sets of first through holes 112 and multiple sets of second through holes 113 side by side on the upper surface of the first partition 106, when the distance between the scraper 5 and the first partition 108 is the closest, the upper ends of multiple sets of screws 403 are respectively fitted into multiple sets of first through holes 112, and the upper ends of multiple sets of movable shafts 404 are respectively fitted into multiple sets of second through holes 113. When the second lifting mechanism 4 drives the scraper 5 to move downward to the upper port of the filter bag 2, the two drive motors 905 move to the inner side of the two recessed folded edges 114, which can further reduce the volume of the entire device.

[0044] Example 3:

[0045] Based on Example 2, as follows Figures 2-3 , Figure 7 and Figures 12-13As shown, the sealing mechanism 6 includes multiple horizontally bolted support strips 601 connected to the inner wall of the dust collection chamber 104; each support strip 601 corresponds to a set of filter bags 2; each support strip 601 has a vertically fixed mounting sleeve 602 inserted into it; each mounting sleeve 602 has a third rotating shaft 603 vertically slidingly inserted into it, and any one of the third rotating shafts 603 can rotate within its corresponding mounting sleeve 602; the upper ends of each third rotating shaft 603 are horizontally bolted to a sealing disc 604; each sealing disc 604 can be slidably inserted into the lower end of each set of filter bags 2; each sealing disc 604 has a tension spring 605 vertically arranged below it; the lower ends of each tension spring 605 are bolted to... Multiple sets of mounting sleeves 602 are attached to the upper ends of multiple sets of tension springs 605, which respectively abut against the lower surfaces of multiple sets of sealing discs 604. Multiple sets of sealing discs 604 have coaxially welded polygonal prisms 606 on their upper surfaces. All polygonal prisms 606 are regular polygonal prisms, and their upper ends are pyramidal. Each set of polygonal prisms 606 has a coaxially arranged protruding post 607 on its upper surface. The upper ends of the protruding posts 607 are respectively welded to the lower surfaces of multiple sets of scraper discs 5. Each set of protruding posts 607 has a vertically protruding insertion hole 608 adapted to the polygonal prism 606 on its lower surface. By sliding the multiple sets of polygonal prisms 606 into the insertion holes 608, the multiple sets of scraper discs 5 can drive the multiple sets of sealing discs 604 to rotate synchronously. In use, when the polygonal prism 606 is not inserted into the insertion hole 608, under the elastic action of the tension spring 605, the sealing disc 604 is located inside the lower port of the filter bag 2, and the edge of the sealing disc 604 slides against the inner wall of the filter bag 2, thereby sealing the lower port of the filter bag 2. Air cannot push the sealing disc 604 downwards when flowing inside the filter bag 2. During the downward rotation of the scraper 5, the upper end of the polygonal prism 606 slides into the insertion hole 608, causing the scraper 5 to drive the sealing disc 604 to rotate synchronously. As the scraper 5 continues to move downwards, the sealing disc 604 will also rotate under the pressure of the scraper 5. The downward movement of the pressing disc 604 and its removal from the lower port of the filter bag 2 allows the sealing disc 604 to move into the dust collection chamber 104. Due to the rotation of the sealing disc 604, the dust falling on the upper surface of the sealing disc 604 is moved into the dust collection chamber 104 under the action of centrifugal force, thereby discharging the dust into the dust collection chamber 104 and effectively ensuring the dust removal effect of the filter bag 2. After the scraper disc 5 moves upward to its reset position, the polygonal prism 606 disengages from the insertion hole 608, and the sealing disc 604 moves back into the lower port of the filter bag 2 under the elastic action of the tension spring 605, ensuring the airflow effect.
