[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] The purpose of this specific embodiment is to provide an air duct cleaning device to solve the problems of manual cleaning of the air duct in the prior art, such as time-consuming and labor-intensive, inability to clean completely, and easy incomplete cleaning.

[0032] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0033] See also Figure 1-6 In this embodiment, the air duct cleaning device includes a fixed base 1, a movable base 2, two chucks 3, a fan 4, a driving structure, a spray assembly, and a brush head assembly. The two chucks 3 are used to clamp the steel rings 501 at both ends of the air duct 5, and the two chucks 3 are respectively arranged on the fixed base 1 and the movable base 2. Figure 4 As shown, the fan 4 is arranged on the fixed base 1 or the movable base 2. As long as the air outlet of the fan 4 faces the steel ring 501 of the air guide tube 5 and the fan 4 can blow air into the inside of the air guide tube 5 to expand and inflate the air guide tube 5, the air guide tube 5 is fixed at this time to prepare for cleaning. The two driving structures drive the two chucks 3 to rotate synchronously respectively, thereby driving the air guide tube 5 to rotate synchronously with the chucks 3. Figure 1 As shown, the spray assembly includes a fixed bracket 6, an outer nozzle 7, an inner nozzle 8, an inner pipeline 10 and an outer pipeline 9, wherein the bracket 6 can be fixed on the ground or fixed on the fixed base 1; the inner pipeline 10 is connected to the inner nozzle 8, and the outer pipeline 9 is connected to the outer nozzle 7. The outer nozzle 7 is arranged at the upper end of the bracket 6 and is located above the outside of the air guide 5, so the outer nozzle 7 can spray water to clean the outer surface of the air guide 5; the inner nozzle 8 is located in the air guide 5 and can spray water to clean the inner surface of the air guide 5. A water tank 11 is fixed on the base assembly, and a first pump body 13 is arranged in the water tank 11. The inner pipeline 10 and the outer pipeline 9 are connected to the first pump body 13. In this way, the first pump body 13 provides power to pump water to the outer nozzle 7 and the inner nozzle 8 through the outer pipeline 9 and the inner pipeline 10, so that the outer nozzle 7 and the inner nozzle 8 spray high-pressure water on the outer surface and the inner surface of the air guide 5 respectively. Specifically, three inner pipes 10 are provided, that is, they are connected to three inner nozzles 8, and the three inner nozzles 8 spray water from three different directions respectively, and there is a certain distance between the three inner nozzles 8, so that when the air guide tube 5 rotates, the inner surface of the air guide tube 5 can be better cleaned without dead angles. Preferably, the spray assembly also includes a detergent tank 12 for containing detergent, and a second pump body 14 is provided in the detergent tank 12, and the inner pipe 10 and the outer pipe 9 are also connected to the detergent tank 12, so that the detergent can be sprayed on the inner nozzle 8 and the outer nozzle 7 first, and then water can be sprayed for cleaning to ensure that the cleaning is clean. Optionally, the first pump body 13 and the second pump body 14 are both hydraulic pumps. In addition, the air duct cleaning device also includes a brush head assembly, which includes a brush roller 25 and a power source. The power source provides rolling power for the brush roller 25. The power source can be an electric motor or a motor. The output shaft of the power source is transmission-connected to the brush roller 25, and the brush roller 25 is in contact with the outer surface of the air duct 5. In this way, the dirt on the outer surface of the air duct 5 that cannot be cleaned by spraying water from the external nozzle 7 can be brushed away by the brush roller 25.

[0034] With such arrangement, the air guide tube 5 is caused to rotate by the driving structure, and the inner and outer surfaces of the air guide tube 5 are cleaned by the inner nozzle 8 and the outer nozzle 7 through the first pump body 13 in the water tank 11. The entire process is realized by power, and no manpower and time are required. Moreover, the air guide tube 5 is cleaned comprehensively, and the brush roller 25 is rolled by the power source, which can also brush off the strong dirt on the outer surface of the air guide tube 5 and clean it.

[0035] As an optional implementation, Figure 5-6 As shown, two brush rollers 25 are provided, and the vertical plane where the central axis of the air guide tube 5 is located is used as the symmetry plane, and the two brush rollers 25 are symmetrically arranged on both sides of the air guide tube 5. The power source is a second motor 26 arranged on the fixed base 1, as shown in FIG. Figure 5 As shown, the output shaft of the second motor 26 is connected to the first gear 27, and the ends of the two brush rollers 25 are connected to the second gear 28, the two second gears 28 are the same size, and the two second gears 28 are meshed with the first gear 27, so that the second motor 26 drives the two brush rollers 25 to roll to brush away dirt. If the speed of the brush roller 25 is to be changed, the transmission ratio of the first gear 27 to the second gear 28 can be adjusted to adjust the speed of the brush roller 25.

[0036] With such arrangement, the dirt on the surface of the air guide tube 5 can be brushed off more thoroughly by the two brush rollers 25, and it is more labor-saving to provide power through the motor, and the gear transmission can keep the two brush rollers 25 at the same rotation frequency.

[0037] As an optional implementation, the second motor 26 is fixed on the fixed base 1, and the air duct cleaning device further includes two lifting mechanisms capable of rising and falling in the vertical direction, the two lifting mechanisms are respectively arranged on the fixed base 1 and the movable base 2, and the two chucks 3 and the two driving structures are respectively located on the two lifting mechanisms, and the fan 4 is arranged on the lifting mechanism on the fixed base 1. Specifically, Figure 2 As shown, the two lifting mechanisms each include a box 15 and two telescopic cylinders 19. The box 15 is a cube with a quadrilateral bottom surface. The chuck 3 and the driving structure are both arranged in the corresponding box 15. Since the chuck 3 needs to contact the steel ring 501 of the air guide tube 5, a circular hole can be opened on the side of the box 15 for the end of the air guide tube 5 to extend into the box 15, thereby achieving contact between the chuck 3 and the air guide tube 5. The fan 4 is located in the box 15 on the fixed base 1, and the two telescopic cylinders 19 are relatively arranged on the outside of the box 15, and one end of the two telescopic cylinders 19 is connected to the base assembly, and the other end is fixedly connected to the box 15. In this way, when the telescopic cylinder 19 is extended and retracted in the vertical direction, it can drive the box 15 and the components in the box 15 to rise and fall.

[0038] With such arrangement, since the brush head assembly is fixed, when the air guide tube 5 of different diameters is replaced, the telescopic cylinders 19 of the two lifting mechanisms are controlled to rise and fall synchronously, so that the central axes of the two chucks 3 can be kept in the same horizontal line, and the position of the air guide tube 5 can be adjusted so that the outer surfaces of the air guide tubes 5 of different models are always in contact with the brush roller 25.

[0039] In a preferred embodiment, the outer portion of the box body 15 is provided with a track assembly for cooperating with the telescopic cylinder 19 for telescoping. Figure 1As shown, the track assembly includes a convex rail 20 and a concave groove, wherein the convex rail 20 is arranged outside the box 15, and the concave groove 21 is arranged on the base assembly, that is, the concave groove on the fixed base 1 is arranged on the fixed base 1, and the concave groove on the mobile base 2 is arranged on the fixed base 1, and the convex rail 20 and the concave groove 21 are both extended in the vertical direction and the two are matched. Preferably, two convex rails 20 are arranged on the outside of each box 15, and the two convex rails 20 are arranged on the outside of the box 15 relatively, and the telescopic cylinder 19 is a hydraulic oil cylinder.

[0040] With such arrangement, the rail assembly cooperates with the lifting and lowering of the telescopic cylinder 19, so that the box body 15 can maintain stability during the lifting process to avoid shaking.

[0041] As an optional implementation, Figure 4 As shown, each driving structure includes a first motor 22 and a reducer 23, the reducer 23 is connected to the output shaft of the first motor 22, the reducer 23 includes a reduction gear, and a gear ring 24 is provided on the outer periphery of the chuck 3, the gear ring 24 is meshed with the outer reduction gear, so the rotational power of the first motor 22 is transmitted to the chuck 3 through the reducer 23, thereby realizing the rotation of the chuck 3. Preferably, the two first motors 22 rotate synchronously and the two reducers 23 have the same structure.

[0042] As an optional implementation, Figure 3-4 As shown, the chuck 3 includes a main body 301, a cylinder 302, and a claw 303, wherein Figure 3The cam 302 is provided with a support base 31 on the casing 15, and the main disc body 301 is rotatably arranged on the support base 31. The upper edge of the support base 31 is a concave arc profile, which cooperates with the outer surface of the main disc body 301. The support base 31 supports the chuck 3 and does not affect the rotation of the chuck 3; the cylinder body 302 is vertically connected to the main disc body 301, the claw 303 is arranged on the side of the main disc body 301, and the two ends of the cylinder body 302 are provided with a first opening, and the main disc body 301 is provided with a second opening connected to the first opening. Therefore, the inner pipeline 10 can extend into the air guide tube 5 through the two first openings and the second openings of the cylinder body 302, and the claw 303 is against the steel ring 501 of the air guide tube 5, so as to realize the relative fixation of the chuck 3 and the air guide tube 5, and the gear ring 24 is arranged on the outer peripheral surface of the main disc body 301, and the reducer 23 drives the gear ring 24 to rotate, thereby driving the chuck 3 to rotate. Preferably, a flange 32, i.e., a flange flange plate, is provided between the chuck 3 and the fan 4. A hole is opened on the tube of the flange 32, and the internal pipeline 10 extends into the tube of the flange 32 through the hole, and then enters the chuck 3 and the air guide tube 5 in sequence. Because the fan 4 generally has no interface, it needs to be used in conjunction with the flange 32, and the flange 32 plays the role of transmitting wind force. In other embodiments, the chuck 3 also includes a steel ring 501 shaping device, and the shape of the steel ring 501 shaping device is similar to the structure of the claw 303 on the chuck 3, but the force is much greater, and it can be driven by a hydraulic pump to bend the deformed steel ring 501 back to its original shape, so that the steel ring 501 can be stuck on the chuck 3 for cleaning.

[0043] In a preferred embodiment, the chuck 3 further includes a telescopic member connected to the claw 303 , which is used to drive the claw 303 to move radially along the main disk body 301 . Both the telescopic member and the claw 303 are arranged in multiple numbers and are distributed along the circumference of the main disk body 301 .

[0044] With such arrangement, each claw 303 is driven to move by the telescopic member, so that the claw 303 can abut against the steel ring 501 of the air guide tube 5 with different diameters, so that the chuck 3 can adapt to air guide tubes 5 of different models.

[0045] As an optional implementation, Figure 1 and Figure 4 As shown, the fixed base 1 is also provided with an air pump 16 as an air source. The air pump 16 is connected to both the external pipeline 9 and the internal pipeline 10, and then the external and internal surfaces of the air guide tube 5 can be dried through the external nozzle 7 and the internal nozzle 8. The air pump 16 plays a major role in drying the external surface of the air guide tube 5 and plays an auxiliary role in drying the internal surface of the air guide tube 5. The fan 4 mainly blows and dries the internal surface of the air guide tube 5. Each telescopic member is a cylinder 304. The air pump 16 is connected to each cylinder 304 through an air supply pipeline 17. A pressure limiting valve 18 is provided on the air supply pipeline 17, so that the air pump 16 provides telescopic power for the cylinder 304, so that the cylinder 304 telescopes and drives the claw 303 to move.

[0046] With such arrangement, the inner and outer surfaces of the air guide tube 5 can be dried through an air pump 16 , and the telescopic power of the air cylinder 304 can also be provided to adjust the position of the claw 303 .

[0047] As an optional implementation, Figure 1 As shown, the mobile base 2 includes a base 201, a roller 202 and a fixed track 203. The roller 202 is arranged at the bottom of the base 201 and extends into the fixed track 203. The fixed track 203 extends in the horizontal direction, so the roller 202 can be displaced relative to the fixed base 1 along the horizontal direction of the fixed track 203, thereby driving the box 15 on the base 201 and various components in the box 15 to move. Specifically, the base 201 or the box 15 can be pushed and pulled manually to displace the roller 202 relative to the fixed base 1; or a motor can be installed on the roller 202 to drive the roller 202 to rotate by electricity to achieve the movement of the base 201.

[0048] In a preferred embodiment, Figure 1 and Figure 6 As shown, a rodless sliding cylinder 29 is horizontally provided on the bracket 6 , and the outer nozzle 7 is fixedly arranged on the rodless sliding cylinder 29 , so that the outer nozzle 7 can move horizontally relative to the bracket 6 .

[0049] With such arrangement, the outer nozzle 7 moves horizontally, and can clean different positions in the length direction of the air guide tube 5, thereby achieving cleaning without dead angles, and making the outer surface of the air guide tube 5 cleaner.

[0050] In a preferred embodiment, Figure 1 As shown, the air duct cleaning device also includes an electric control system 30, which is similar to a controller. The electric control system 30 is electrically connected to the first pump body 13, the second pump body 14, the pressure limiting valve 18, the first motor 22, the second motor 26, and the two telescopic cylinders 19 to control the opening and closing of the first pump body 13, thereby controlling whether water is sprayed on the surface of the air duct 5; controlling the opening and closing of the second pump body 14, thereby controlling whether a cleaning agent is sprayed on the surface of the air duct 5; controlling the pressure limiting valve 18 to control the radial extension degree of the cylinder 304 along the main disk body 301; controlling the opening and closing of the first motor 22, thereby controlling whether the chuck 3 and the air duct 5 rotate; controlling the opening and closing of the second motor 26, thereby controlling whether the brush roller 25 rotates; and controlling the two telescopic cylinders 19 to control the height of the box body 15 and the air duct 5.

[0051] With such arrangement, the cleaning process of the air guide tube 5 can be fully automated through the electric control system 30, thereby saving more manpower and time and achieving high efficiency.
