Compared with split air conditioners, it has the advantages of uniform cooling and high comfort.
[0003] During use, central air-conditioning pipes will accumulate harmful substances such as dust, dirt, and bacteria. In order to ensure air quality, staff usually use dust removal devices to clean the inner walls of the pipes on a regular basis. A drive wheel is provided at the bottom of the dust removal device so that it can move on the narrow inner wall of the pipe.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Specific examples are given below.
[0026] like Figure 1-5The dust removal device for central air-conditioning duct is shown as follows, comprising a cleaning machine body 1; the bottom of the cleaning machine body 1 is rotatably connected to multiple sets of driving wheels 11; a cleaning member 12 is installed on the top of the cleaning machine body 1; the end of the cleaning machine body 1 is fixedly connected to a vertical plate 13; the top of the vertical plate 13 is installed with a motor 14; the output end of the motor 14 is fixedly connected to a gear block 15; two sets of limiting rails 16 are fixedly connected to the bottom of the vertical plate 13; the middle of the limiting rail 16 is slidably connected to a rack 17, and the two sets of racks 17 and the gear block 15 are meshed with each other; a scraper 18 is fixedly connected to the bottom of the rack 17, and the two sets of scrapers 18 are in contact with each other; when working, the staff needs to place the cleaning machine body 1 inside the air-conditioning duct that needs to be cleaned, and then the staff can start the motor 14 switch, so that the elastic member 4 at the output end of the cleaning machine body 1 slowly rotates and during the rotation process, the two sets of racks 1 can be synchronously driven under the action of the gear block 15 7 slides on the inner wall of the limit rail 16 until the ends of the two sets of racks 17 gradually approach the inner wall of the air-conditioning duct, and the motor 14 is turned off to fix the two sets of racks 17. When the driving wheel 11 is working and drives the cleaning machine body 1 to move as a whole inside the duct, the two sets of scrapers 18 provided in contact with the bottom wall of the duct can centrally push the dust cleaned and dropped by the cleaning member 12, and transfer it to a designated position for centralized collection. This step, in conjunction with the two sets of scrapers 18, can improve the cleanliness of the front end of the duct before the driving wheel 11 moves, reduce the accumulation of more dust and impurities at the bottom wall of the scraping duct, and make the driving wheel 11 have more adhesion to its surface during the process of passing over the dust, reduce the problem of the cleaning machine body 1 being blocked from moving in the duct, resulting in difficulty in deep cleaning, and push the dust and other impurities to the same position, which can improve the speed of subsequent staff in cleaning the dust.
[0027] like Figure 1 、 2As shown in Figure 4, the end of the cleaning machine body 1 is fixed with a fixed plate 2; the end of the fixed plate 2 is connected to a baffle 21 by a torsion spring, and the middle part of the baffle 21 is inclined; two sets of vertical rods 22 are fixed to the top of the cleaning machine body 1; the middle part of the vertical rod 22 is rotatably connected to a rotating shaft 23; the end of the rotating shaft 23 is rotatably connected to two sets of belts 24, and the other end of the belt 24 is rotatably connected to the output end of the driving wheel 11; the middle part of the rotating shaft 23 is fixed with a top plate 25, and the middle part of the top plate 25 is arc-shaped; when working, by arranging an inclined baffle 21 on the top of the cleaning machine body 1, when the cleaning member 12 cleans the top wall or side wall of the pipe, the inclined baffle 21 can block the falling impurities, while driving During the rotation of the wheel 11, the two sets of belts 24 provided in conjunction with it can synchronously drive the rotating shaft 23 to rotate in the middle of the vertical pole 22, and the arc-shaped top plate 25 will gradually approach the middle of the baffle 21, and after contacting the inner wall of the baffle 21, the center point of the connection end between the baffle 21 and the fixed plate 2 will be rotated, and then the baffle 21 will be reset and shaken. This step, in conjunction with the baffle 21 provided, can reduce the number of impurities that fall and accumulate in the inner groove of the tooth block 15 or the rack 17, causing trouble when the two are subsequently engaged, and at the same time can reduce the meshing wear between the two. The rotating top plate 25 provided can continuously push the baffle 21 to shake, reducing the amount and time of dust accumulation on its surface.
[0028] like Figure 2 and 5 As shown, a spring rod 3 is fixedly connected to the inner wall of the rack 17; a connecting piece 31 is fixedly connected to the output end of the spring rod 3; a push rod 32 is fixedly connected to the end of the connecting piece 31; during operation, by arranging the spring rod 3 at the end of the rack 17, and when the two sets of racks 17 gradually approach the inner wall of the pipe, the push rod 32 will first contact the inner wall of the pipe, and after the rack 17 continues to move, it will squeeze the output end of the spring rod 3 to retract, so that the overall position of the cleaning machine body 1 is limited. This step, combined with the push rod 32 made of soft material, can reduce the difficulty in observing the distance between the ends of the two sets of racks 17 and the pipe when the cleaning machine body 1 is placed in the pipe position, so that the rack 17 directly contacts the pipe directly, resulting in greater wear and tear. At the same time, it can reduce the resistance generated by the cleaning machine body 1 as a whole during movement.
[0029] like Figure 2As shown, two groups of elastic members 4 are fixed to the bottom of the baffle 21; gaskets 41 are fixed to the ends of the elastic members 4; when working, by arranging two groups of elastic members 4 at the bottom of the baffle 21, when the baffle 21 is reset under the action of the torsion spring, the gasket 41 will first contact the top of the fixed plate 2, and squeeze the middle part of the elastic member 4 to deform, and cooperate with the elastic force generated to make the baffle 21 shake as a whole. This step, under the action of the two groups of elastic members 4, can increase the frequency of the shaking of the baffle 21, further improve the cleanliness of the top of the baffle 21, and reduce the corrosion of the baffle 21 by more dust.
[0030] like Figure 4 As shown, the inner wall of the top plate 25 is fixed with multiple groups of elastic ropes 5; the middle part of the elastic ropes 5 is fixed with a counterweight 51; when working, the elastic ropes 5 are arranged, and when the top plate 25 rotates, the counterweight 51 can hit the inner wall of the top plate 25 under the action of inertia, and pull the middle part of the elastic ropes 5 to deform.

During operation, by providing a rotating wheel 6 in the middle part of the push rod 32, when the push rod 32 is close to the inner wall of the pipe, the wheel 6 will deeply contact the pipe and rotate under the action of friction. This step, combined with the setting of the wheel 6, can further reduce the resistance generated by the cleaning machine body 1 as a whole during movement. At the same time, under the action of the recess of the wheel 6, its stability when rotating in the middle part of the push rod 32 can be improved.
[0032] like Figure 4 As shown, a rubber part 7 is fixedly connected to the middle part of the counterweight 51; when working, the rubber part 7 is set in the middle part of the counterweight 51, and when the counterweight 51 needs to be maintained later, it is only necessary to tear off the rubber part 7. This step, combined with the set rubber part 7, can increase the overall service life of the counterweight 51 and facilitate the removal or installation of the rubber part 7.

When the driving wheel 11 is working and drives the cleaning machine body 1 as a whole to move inside the duct, it contacts the bottom wall of the duct. The two sets of scrapers 18 can centrally push the dust cleaned and dropped by the cleaning member 12 and transfer it to a designated location for centralized collection. By providing an inclined baffle 21 on the top of the cleaning machine body 1, the cleaning member 12 can block the falling impurities when cleaning the top wall or side wall of the pipe. At the same time, when the driving wheel 11 is rotating, the two sets of belts 24 provided in conjunction can synchronously drive the rotating shaft 23 to rotate in the middle of the vertical rod 22, and the arc-shaped top plate 25 will gradually approach the middle of the baffle 21 and contact the inner wall of the baffle 21, so that the baffle 21 and the fixed plate are in contact. 2 The center point of the connection end position is rotated, and then the baffle 21 is reset and shaken. By providing a spring rod 3 at the end of the rack 17, and when the two sets of racks 17 gradually approach the inner wall of the pipe, the top rod 32 will first contact the inner wall of the pipe, and after the rack 17 continues to move, it will squeeze the output end of the spring rod 3 to retract, so that the overall position of the cleaning machine body 1 is limited. By providing two sets of elastic members 4 at the bottom of the baffle 21, and when the baffle 21 is reset under the action of the torsion spring, the gasket 41 will first contact the top of the fixed plate 2 and squeeze the middle part of the elastic member 4 to deform. The elastic force generated is used to make the baffle 21 shake as a whole, and the elastic rope 5 is provided. When the top plate 25 rotates, the counterweight 51 can hit the inner wall of the top plate 25 under the action of inertia, and pull the middle part of the elastic rope 5 to deform. A rotating wheel 6 is provided in the middle of the top rod 32, and when the top rod 32 is close to the inner wall of the pipe, the wheel 6 will deeply contact the pipe and rotate under the action of friction. A rubber part 7 is provided in the middle of the counterweight 51, and when the counterweight 51 needs to be maintained later, the rubber part 7 only needs to be torn off.
