[0038] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] As Figure 1 and Figure 4 shown, the present application provides a central air-conditioning duct cleaning device, including a cleaning robot 1, which is used to clean the inside of the duct by means of various components;

[0041] The cleaning robot 1 includes a housing 2, and a driving assembly is fixedly arranged at the lower end inside the housing 2. The driving assembly includes a first motor 10 fixedly arranged at the lower end inside the housing 2. A first gear 14 is fixedly arranged at the output end of the first motor 10. At the same time, a plurality of groups of support platforms 12 are fixedly arranged on both sides of the lower end inside the housing 2. Two groups of rotating shafts 11 are rotatably arranged between the support platforms 12. A second gear 13 is fixedly arranged at a position where the rotating shaft 11 is close to the first gear 14, and the second gear 13 meshes with the first gear 14. Thus, the first motor 10 drives the second gear 13 by driving the first gear 14, so that the rotating shaft 11 rotates on the support platform 12;

[0042] Meanwhile, driving wheels 7 are fixedly arranged on both sides of the rotating shaft 11, and driven wheels 9 are fixedly arranged on another set of rotating shafts 11. A crawler 8 is drivingly connected between the driving wheel 7 and the driven wheel 9. Thus, when the first motor 10 drives the rotating shaft 11 to rotate by driving the first gear 14, the driving wheel 7 rotates accordingly. Then, the driven wheel 9 is driven to rotate through the crawler 8, thereby enabling the cleaning robot 1 to perform a moving operation in the central air-conditioning duct;

[0043] Moreover, a camera 6 is fixedly arranged at the upper end of the housing 2. The camera 6 is used to capture the images inside the duct and transmit them to the operator for remote monitoring of the cleaning process or fault diagnosis. Meanwhile, lighting lamps 5 are fixedly arranged on both sides of the camera 6. The lighting lamps 5 are used to provide sufficient light so that the cleaning robot 1 can clearly see dirt and obstacles inside the duct;

[0044] As Figures 1-3 shown, a cleaning mechanism 3 is rotatably arranged at the front end of the housing 2. The cleaning mechanism 3 is used to impact the inner wall of the duct to remove dirt;

[0045] The cleaning mechanism 3 includes a rotating cleaning assembly fixedly arranged at the front end of the housing 2. The rotating cleaning assembly is used to clean the stains in the duct by agitation;

[0046] The rotating cleaning assembly includes a mounting plate 30 fixedly arranged inside the housing 2. A second motor 33 is fixedly arranged on the mounting plate 30. The output end of the second motor 33 penetrates through the housing 2 and is fixedly provided with a coupling 31. The coupling 31 is used for smooth transmission of power. Meanwhile, a rotating head 32 is fixedly arranged at one end of the coupling 31. Multiple groups of soft fine hairs (not marked in the figure) are fixedly arranged on the rotating head 32. The soft fine hairs are arranged in a circular pattern on the rotating head 32. Thus, when the second motor 33 smoothly transmits power to the rotating head 32 through the coupling 31, and then the rotating head 32 drives the soft fine hairs to rotate, the dirt and deposits inside the duct can be removed by driving the soft fine hairs to rotate;

[0047] In order to enable the cleaning mechanism 3 to further clean stubborn stains, wiping assemblies 34 are rotatably arranged on both sides of the housing 2. The wiping assemblies 34 are used to further clean stubborn stains through reciprocating wiping;

[0048] The wiping assembly 34 includes a third motor 342 fixedly arranged at the upper end of the housing 2. A connecting piece 341 is fixedly arranged at the output end of the third motor 342. Thus, the third motor 342 can drive the connecting piece 341 to rotate;

[0049] And at one end of the connecting piece 341 away from the third motor 342, an L-shaped plate 343 is fixedly arranged. The L-shaped plate 343 is used to provide sufficient stability for the overall structure. At the same time, fixing rings 344 are fixedly arranged at the upper and lower ends inside the L-shaped plate 343. A fixing sleeve rod 349 is fixedly arranged on the fixing ring 344. Both ends of the fixing sleeve rod 349 penetrate through the L-shaped plate 343 and are fixedly connected to the L-shaped plate 343 through the fixing ring 344;

[0050] It should be noted that through holes are opened at both ends of the fixing sleeve rod 349. At the same time, fixing bolts 345 are threadedly connected to the through holes. And two groups of sliding rods 346 are slidably arranged inside the fixing sleeve rod 349. A plurality of positioning holes 347 are opened on the sliding rod 346. The positioning holes 347 correspond to the through holes on the fixing sleeve rod 349 and are locked by the fixing bolts 345;

[0051] Thus, when the fixing bolt 345 fits with the fixing sleeve rod 349, the position of the sliding rod 346 can be fixed. When the fixing bolt 345 is separated from the fixing sleeve rod 349, the position of the sliding rod 346 can be adjusted, so that the sliding rod 346 slides along the direction of the fixing sleeve rod 349, facilitating the adjustment of the wiping assembly 34 to adapt to working environments of different heights. Thus, the wiping assembly 34 can wipe different pipes without being disassembled and reinstalled;

[0052] At the same time, a brush head 348 is fixedly arranged at one end of the sliding rod 346. The brush head 348 is used to directly contact the inside of the pipe, so as to remove stubborn dirt through reciprocating motion;

[0053] Before the cleaning operation starts, the height of the sliding rod 346 of the wiping assembly 34 and the fixing sleeve rod 349 can be adjusted according to the size of the pipe to be cleaned. After the height is adjusted to a suitable position, the cleaning operation can be carried out;

[0054] At this time, the third motor 342 will drive the connecting piece 341 to drive the sliding rod 346 and the brush head 348 to perform reciprocating motion through the L-shaped plate 343, so as to further remove stains from the pipe;

[0055] As Figure 1 and Figure 5 shown, at the same time, a dust suction mechanism 4 is fixedly arranged at the tail end inside the housing 2. The dust suction mechanism 4 is used to clean the dust, debris, microorganisms and other dirt remaining inside the pipe by generating a strong suction force;

[0056] The dust suction mechanism 4 includes a support column 45 fixedly arranged at the inner end of the housing 2. At the upper end of the support column 45, a dust suction pump 40 is fixedly arranged. The dust suction pump 40 provides the power source for the dust suction mechanism 4. At the same time, a temporary storage box 41 is fixedly arranged at one end of the dust suction pump 40. The temporary storage box 41 is used for temporarily storing dust, debris, microorganisms and other dirt. A connecting pipe (not marked in the figure) is fixedly arranged between the temporary storage box 41 and the dust suction pump 40 to facilitate the dust suction pump 40 to transfer the dust, debris, microorganisms and other dirt in the temporary storage box 41;

[0057] At the same time, a plurality of suction pipes 43 are fixedly arranged at one end of the temporary storage box 41 away from the connecting pipe. At the end of the suction pipe 43, a suction nozzle 42 is fixedly arranged. The suction nozzle 42 is used for sucking dust, debris, microorganisms and other dirt in all directions;

[0058] At the same time, a storage box 44 is fixedly arranged at a position near the dust suction pump 40 at the inner end of the housing 2. The storage box 44 is communicated with the dust suction pump 40 to facilitate the temporary storage of the collected dust;

[0059] After the cleaning mechanism 3 cleans the dust adhering to the inner part of the pipeline, the dust suction mechanism 4 is used to absorb the cleaned dust, and the collected dust is temporarily stored in the storage box 44.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
