[0036] The heat recovery mechanism of the building heating, ventilation and air conditioning system facilitates the cleaning of the surface of the inner box 202. The specific implementation method is as follows:

[0037] The outer shell 10 is set as a cylindrical hollow shell, and a bracket 101 is fixedly connected to the surface of the outer shell 10; a lid 20 is arranged on the surface of the outer shell 10, and a first latch 201 is rotatably installed on the surface of the lid 20, and the other end of the first latch 201 is embedded in the surface of the outer shell 10. An inner box 202 is arranged inside the outer shell 10, and a convex block 204 is fixedly connected to the surface of the inner box 202. Second latches 203 are symmetrically and rotatably installed at the bottom of the lid 20, and the other ends of the second latches 203 are in contact with the surface of the convex block 204. An air inlet 50 is embedded in one side surface of the outer shell 10, and an air outlet 60 is embedded in the other side surface of the outer shell 10. A rotating mechanism is arranged inside the outer shell 10, and the rotating mechanism includes: a motor 30 is installed on the surface of the bracket 101, and the output shaft of the motor 30 is inserted into the outer shell 10 and fixedly connected to a rotating shaft 301. A groove 302 is embedded at the bottom of the inner box 202, and the rotating shaft 301 is arranged inside the groove 302. A connecting rod 303 is fixedly connected to the bottom of the lid 20, and a stirring fan 304 is installed on the surface of the connecting rod 303. A scraping plate 305 is fixedly connected to the inner wall of the outer shell 10. The inner box 202 is rotatably connected to the outer shell 10. The end of the scraping plate 305 is attached to the inner wall of the inner box 202, and the inner box 202 is rotatably connected to the scraping plate 305. The second latch 203 is snap-fitted to the bottom surface of the convex block 204, and the convex block 204 is slidably connected to the second latch 203, and the second latch 203 is rotatably connected to the lid 20. A card slot is arranged inside the groove 302, and a latch is arranged on the surface of the rotating shaft 301, and the rotating shaft 301 is snap-fitted to the groove 302. The stirring fan 304 is arranged inside the inner box 202, and the inner box 202 is rotatably connected to the stirring fan 304.

[0038] An external device drives the indoor air to enter the interior of the housing 10 from the air inlet 50. At this time, the hot air stays inside the housing 10, and the hot air heats the surface of the inner tank 202. The inner tank 202 heats the water inside. When the hot air encounters the inner tank 202, the moisture inside the hot air condenses on the outer wall surface of the inner tank 202. Then, the motor 30 is started. The motor 30 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the inner tank 202 to rotate through the groove 302. The second clamping block 203 drives the convex block 204 to slide inside the second clamping block 203. At this time, the rotating shaft 301 drives the internal moisture to rotate, and the connecting rod 303 stirs the water to make the water evenly heated. At this time, the inner tank 202 rotates at the end of the scraping plate 305, and the scraping plate 305 can clean the surface of the inner tank 202, scraping off the water droplets and scale on the surface of the inner tank 202. Finally, the hot air is discharged through the air outlet 60. Rotate the first clamping block 201 so that the end of the first clamping block 201 loses engagement with the bracket 101. At this time, pull up the lid 20. The lid 20 drives the convex block 204 to move upward through the second clamping block 203. The convex block 204 drives the inner tank 202 to move upward. The inner tank 202 drives the groove 302 to lose engagement with the rotating shaft 301, and the inner tank 202 is taken out from the interior of the housing 10. Rotate the second clamping block 203 so that the end of the second clamping block 203 loses engagement with the convex block 204, and the lid 20 can be removed from above the inner tank 202, which is convenient for cleaning the inner tank 202 and the housing 10.

[0039] The heat recovery mechanism of the building heating, ventilation and air conditioning system can collect water to prevent water overflow. The specific implementation method is as follows:

[0040] A water collecting tank 40 is fixedly connected to the surface of the bracket 101, and an alarm mechanism is arranged inside the water collecting tank 40. The alarm mechanism includes: sliding rods 401 are symmetrically and fixedly connected inside the water collecting tank 40, and a floating block 402 is sleeved and installed between the two sliding rods 401. A pressure sensor 403 is installed on the top inner wall of the water collecting tank 40, and an alarm 405 is installed on the surface of the water collecting tank 40. A water guide pipe 404 is connected between the water collecting tank 40 and the housing 10. The sliding rod 401 is slidably connected to the floating block 402, and the floating block 402 is arranged corresponding to the position of the pressure sensor 403.

[0041] When the hot air encounters the surface of the inner tank 202, the moisture inside the hot air condenses. The water flows into the interior of the water collecting tank 40 through the water guide pipe 404 to collect the waste water, and the waste water can be recycled. At this time, the floating block 402 moves upward along the liquid surface of the water flow, and the floating block 402 moves upward along the surface of the sliding rod 401. When the surface of the sliding rod 401 contacts the surface of the pressure sensor 403, the pressure sensor 403 receives the thrust of the floating block 402, and the floating block 402 controls the alarm 405 to turn on. The alarm 405 flashes and gives an alarm, reminding the user that the water collecting tank 40 needs to drain the water into the water collecting tank 40.

[0042] Working principle: When using the heat recovery mechanism of the building heating, ventilation and air conditioning system, a stirring fan 304 and a scraping plate 305 are provided to facilitate the cleaning of the surface of the inner box 202. A pressure sensor 403, a water conduit 404 and an alarm 405 are provided to collect water, prevent water overflow, and increase the overall practicality.

The scope of the present invention is defined by the appended claims and their equivalents.
