[0031] As described in the background art, the interior of the cigar room needs to be ventilated for a long time, so the fan needs to run continuously for a long time. When the fan runs for a long time, more dust and debris will accumulate in the middle of the protective net at the front end, so it needs to be manually handled regularly.
[0032] In order to solve this technical problem, the utility model provides a ventilation structure for a cigar and tobacco leaf drying room, which is applied to the ventilation of the cigar room and the self-cleaning of the ventilation structure.
[0033] Specifically, please refer to Figure 1 and Figure 8 The ventilation structure of the cigar and tobacco leaf drying room specifically includes a ventilation bearing frame 1, an internal ventilation and dust cleaning mechanism 2, a dust storage mechanism 3, a main control box 26 and a controller 27.

The wind speed inside the ventilation bearing frame 1 is monitored in real time by a wind speed sensor provided inside the controller 27. If the internal wind speed is abnormal, the protective grid 21 is cleaned by the internal ventilation and dust cleaning mechanism 2, thereby achieving the purpose of automatic cleaning.
[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0036] Example 1:
[0037] Please refer to Figure 2-Figure 6A ventilation structure for a cigar and tobacco leaf drying room, the internal ventilation and ash cleaning mechanism 2 includes a guide frame 4, a polished rod 5, a servo motor 6, a threaded rod 7, a cross bracket 8, a transmission assembly, a heat dissipation assembly and a ash cleaning assembly. The middle part of the ventilation bearing frame 1 is fixedly connected to four guide frames 4 in a circular array, the middle parts of three of the four guide frames 4 are fixedly connected to polished rods 5, one end of one of the four guide frames 4 is fixedly connected to a servo motor 6, the transmission end of the servo motor 6 is rotatably connected to the threaded rod 7, the threaded rod 7 is rotatably connected to the middle part of the guide frame 4, the surface of the polished rod 5 is slidably connected to the cross bracket 8, and the cross bracket 8 is threadedly connected to the threaded rod 7.
[0038] Specifically, the transmission assembly includes a heat dissipation motor 9, a transmission shaft 10 and a limit block 11. The surface of the cross bracket 8 is fixedly connected to the heat dissipation motor 9, the transmission end of the heat dissipation motor 9 is rotatably connected to the transmission shaft 10, and the surface of the transmission shaft 10 is symmetrically fixedly connected to the limit block 11.
[0039] Specifically, the heat dissipation assembly includes a M-shaped bracket 12, a sleeve 13, a limiting groove 14 and a heat dissipation fan blade 25. The middle part of the ventilation supporting frame 1 is fixedly connected to the M-shaped bracket 12, the middle part of the M-shaped bracket 12 is rotatably connected to the sleeve 13, the inner wall of the sleeve 13 is symmetrically provided with limiting grooves 14, the outer wall of the sleeve 13 is fixedly connected to a plurality of heat dissipation fan blades 25 in a circular array, the transmission shaft 10 is slidably connected to the middle part of the sleeve 13, and the limiting block 11 is slidably connected to the inner wall of the limiting groove 14.
[0040] Specifically, the dust cleaning component includes a supporting link 15, a wedge block 16, a bearing 17, a linkage ring 18, a slot 19, a cleaning brush plate 20 and a protective grid 21. The end of the transmission shaft 10 away from the heat dissipation motor 9 is fixedly connected to the wedge block 16, and both ends of the wedge block 16 are fixedly connected to the wedge block 16. The inner wall of the ventilation bearing frame 1 is fixedly connected to the bearing 17, and the inner wall of the bearing 17 is fixedly connected to the linkage ring 18. A plurality of slots 19 are provided in a circular array on the side of the linkage ring 18 close to the wedge block 16. The side of the linkage ring 18 away from the slot 19 is fixedly connected to the cleaning brush plate 20. One end of the ventilation bearing frame 1 is fixedly connected to the protective grid 21, and the protective grid 21 is in close contact with the surface of the cleaning brush plate 20.
[0041] Through the above structural design, if the air flow rate inside the ventilation bearing frame 1 is small when the heat dissipation fan blades 25 rotate, the interior of the protective grid 21 is blocked, and the servo motor 6 is controlled to start. The servo motor 6 drives the threaded rod 7 to rotate so that the cross bracket 8 slides on the surface of the guide frame 4 and the light rod 5 toward the side of the protective grid 21. While the protective grid 21 slides, it pushes the heat dissipation motor 9, the transmission shaft 10 and the limit block 11 to slide in the middle of the sleeve 13 toward the side of the protective grid 21. While the transmission shaft 10 moves, it pushes the support connecting rod 15 at the front end to drive the wedge block 16 to be inserted into the insertion hole. The inner wall of the slot 19, since the heat dissipation motor 9 is in the turned-on state, the heat dissipation motor 9 drives the supporting connecting rod 15 and the wedge block 16 at the front end of the transmission shaft 10 to rotate, and the wedge block 16 rotates while driving the linkage ring 18 and the cleaning brush plate 20 to rotate through the slot 19. Since the cleaning brush plate 20 is in close contact with the surface of the protective grid 21, the cleaning brush plate 20 can clean the dust on the surface of the protective grid 21 while rotating. After cleaning, the servo motor 6 is turned on to reverse, and the reversal of the servo motor 6 can drive the cross bracket 8 to move to the side away from the protective grid 21, thereby separating the wedge block 16 from the slot 19.
[0042] Example 2:
[0043] The ventilation structure of the cigar tobacco leaf drying room provided in Example 1 is further optimized. Specifically, Figure 7 As shown, the dust storage mechanism 3 includes a connecting cavity 22, a storage box 23 and a handle 24. The surface of the ventilation supporting frame 1 is fixedly connected to the connecting cavity 22, the connecting cavity 22 is connected to the interior of the ventilation supporting frame 1, the middle part of the connecting cavity 22 is slidably connected to the storage box 23, and the surface of the storage box 23 is fixedly connected to the handle 24.
[0044] Through the above-mentioned structural design, after the cleaning brush plate 20 has completed cleaning the dust on the surface of the protective grid 21, it will automatically fall downward to the middle of the storage box 23 due to gravity. When the storage box 23 is full of debris, the storage box 23 can be taken out from the middle of the connecting cavity 22 for cleaning by pulling the handle 24.
[0045] Example 3:
[0046] The ventilation structure of the cigar and tobacco leaf drying room provided in Example 1 and Example 2 is further optimized. Specifically, Figure 8 As shown, the main control box 26 is internally provided with a single chip microcomputer, an audible and visual alarm, and a wireless transceiver module.
[0047] Specifically, the controller 27 is internally provided with a wind speed sensor, an analog voltage control module and a wireless transceiver module.
[0048] Through the above-mentioned structural design, the wind speed sensor inside the controller 27 monitors that the wind speed inside the ventilation bearing frame 1 is low and sends the real-time monitoring information to the main control box 26 through the wireless transceiver module. After the single-chip microcomputer compares the wind speed data, if the flow is low, it sends an operation instruction to the analog voltage control module inside the controller 27 through the wireless transceiver module. The analog voltage control module can control the rotation state of the servo motor 6 and the heat dissipation motor 9, and cooperates with the internal ventilation and dust cleaning mechanism 2 to realize automatic cleaning of the dust on the surface of the protective grid 21.
