The belt transmission assembly 1504 can rotate under the action of the motor 1506, thereby driving the first winding drum 1503 and the second winding drum 1505 to rotate.

[0025] In this embodiment, Figure 3 and Figure 5 As shown, an airbag belt 1507 is wound around the outside of the first winding drum 1503, and a first connecting pipe 1508 is fixed to the head end of the airbag belt 1507, an air pump 1510 is fixed to the front side of the first storage frame 1501, and a second connecting pipe 1509 is fixed to the rear side of the air pump 1510, the first connecting pipe 1508 passes through the front side of the first storage frame 1501 and is rotatably connected to the second connecting pipe 1509, the first connecting pipe 1508 and the second connecting pipe 1509 serves to connect the air pump 1510 and the airbag belt 1507. After the first winding drum 1503 rotates to release the airbag belt 1507, the air pump 1510 inflates the airbag belt 1507. The airbag belt 1507 expands in the HVAC duct 9 and there is a certain gap between it and the inner wall of the HVAC duct 9. Then, the descaling agent can be passed into the HVAC duct 9.

The inner top of the water tank 1 and an inner wall of the water tank 1 are both rotatably connected with rollers 1512. The pull rope 1511 passes around the two rollers 1512. While the first winding drum 1503 rotates to release the airbag belt 1507, the second winding drum 1505 rotates to reel in the pull rope 1511. The pull rope 1511 can pull the airbag belt 1507 into the HVAC pipe 9, and the roller 1512 plays a role in supporting and guiding the pull rope 1511.

[0027] In this embodiment, Figure 3 and Figure 5 As shown, the end of the pull rope 1511 passes through the HVAC pipe 9, the top of the water tank 1 and the second storage frame 1502 and is wrapped around the outside of the second winding drum 1505.

[0029] The use method and advantages of the present invention: The HVAC equipment that is convenient for cleaning dirt has the following working process: like Figures 1 to 7As shown: First, use the mounting block 2 and external bolts to install the water tank 1 on the wall. The HVAC pipe 9 is pre-buried underground. The operation of the entire device is controlled by operating the control panel 3. After opening the cover 5, water is passed into the water tank 1. The electric heating plate 7 heats the water. The water circulates in the water tank 1 and the HVAC pipe 9 to meet the heating needs. The filter box 13 filters the water. Before cleaning the HVAC pipe 9, first open the drain valve 11 and use the drain pipe 10 to drain the water in the water tank 1 and the HVAC pipe 9. Then raise the movable block 1515 to open the opening 1513. The belt drive assembly 1504 drives the first winding drum 1503 and the second winding drum 1505 to rotate. The first winding drum 1 While 503 releases the airbag belt 1507, the second reel 1505 reels the drawstring 1511, and the drawstring 1511 pulls the airbag belt 1507 into the HVAC duct 9. Then, the air pump 1510 is used to inflate the airbag belt 1507. The airbag belt 1507 expands and blocks the opening 1513. There is a certain gap between the airbag belt 1507 and the inner wall of the HVAC duct 9. Then, the descaling agent is passed into the water tank 1 and the top of the HVAC duct 9 is submerged in the descaling agent. The descaling agent naturally flows into the HVAC duct 9, and the dirt on the inner wall of the HVAC duct 9 is soaked in the descaling agent. After waiting for a certain period of time, the dirt is drained out using the drainage pipe 10. Finally, the above operation is repeated in reverse to deflate and reel the airbag belt 1507.

[0030] In summary, this HVAC equipment that is easy to clean dirt achieves the purpose of cleaning by filtering, regular cleaning, and reducing the use of descaling agents, thus meeting people's usage needs.
