The joint 49 is energized, and the resistance wire 48 starts to heat up to increase the temperature of the honeycomb block 25. Due to the action of the switching disk 26, the air can only pass through the multiple heating holes 46 inside the honeycomb block 25 to enter the bottom of the heating tube 18. After passing through the bottom air pump 17 and the connecting pipe, the heated air has entered the interior of the lower partition cover 16. By rotating the conversion disk 27, the two ends of the air duct 50 are aligned with the air inlet pipe 28 and the intermediate pipe 36 respectively, so that the air on the top of the upper partition cover 13 can enter the interior of the heating tube 18 through the air inlet pipe 28, thereby achieving the effect of drying Chinese medicine with two air circulation paths.

[0040] Reference Figure 2 , Figure 3 , Figure 4 and Figure 7 In a preferred embodiment, the transmission mechanism includes a slide rail 31 fixedly connected to the inner walls on both sides of the drying chamber 23, a slide plate 30 is slidably connected to one side of the slide rail 31, a linkage plate 21 is fixedly connected to one side of the slide plate 30, one end of the mounting frame 32 is fixedly connected to the linkage plate 21, a slot is provided between the drying chamber 23 and the isolation chamber 24 near the connection between the mounting frame 32 and the linkage plate 21, the mounting frame 32 moves inside the slot, a moving frame 12 is fixedly connected to the upper surface of the linkage plate 21, and a motor 22 is fixedly connected to a position on the inner wall of one side of the drying chamber 23 near the linkage plate 21.

[0041] One end of the output shaft of the motor 22 is fixedly connected to a threaded rod 19, one end of the threaded rod 19 is threadedly connected to a moving block 20, the moving block 20 is fixedly connected to a linkage plate 21, and a plurality of openings are provided on the upper surface of the moving frame 12, and the width of the openings is the same as that of the exhaust slit 6.

[0042] The heating mechanism includes a honeycomb block 25 fixedly connected to the interior of the heating tube 18, an air duct 47 is arranged inside the honeycomb block 25, a plurality of heating holes 46 are arranged inside the heating tube 18 near the air duct 47, a resistance wire 48 is arranged inside the heating tube 18 near the heating holes 46, and joints 49 are respectively arranged at both ends of the resistance wire 48.

[0043] The top of the honeycomb block 25 is rotatably connected to a switching disk 26, the upper surface of the switching disk 26 is fixedly connected to a driving bevel gear 38, one side of the heating tube 18 is rotatably connected to a rotating rod, one end of the rotating rod is fixedly connected to a driven bevel gear 37, the other end of the rotating rod is fixedly connected to a second rotating plate 35, the top of the second rotating plate 35 is rotatably connected to a branch rod, and the branch rod is rotatably connected to the linkage frame 33.

[0044] In this embodiment, the air is heated through the air holes on the top of the lower partition cover 16 to squeeze the room temperature air inside the drying chamber 23 upward. Since the multiple exhaust slits 6 on the top of the outer shell 1 are open at this time, the room temperature air is discharged through the exhaust slits 6. The temperature sensor detects that the air temperature inside the outer shell 1 has risen, and controls the motor 22 to rotate, driving the threaded rod 19 to rotate so that the moving block 20 moves back and forth, pushing the linkage plate 21 and the moving frame 12 to slide, thereby realizing the relative sliding between the moving frame 12 and the multiple exhaust slits 6, thereby controlling the opening and closing of the multiple exhaust slits 6, closing the multiple exhaust slits 6, and allowing the hot air inside the drying chamber 23 to pass through the multiple drying holes 45 on the Chinese medicine plate 15, thereby taking away the moisture inside the Chinese medicine. Due to the oblique installation of the Chinese medicine plate 15, part of the hot air that cannot pass through the drying holes 45 floats upward along the bottom of the Chinese medicine plate 15, and the hot air continues to heat the upper Chinese medicine plate 15 through multiple air guides 44, thereby accelerating the air flow and improving the drying efficiency.

[0045] Furthermore, after closing the multiple exhaust slits 6, the movement of the linkage plate 21 drives the mounting frame 32, the linkage frame 33 and the branch rod to move, respectively pushing the first rotating plate 29 and the second rotating plate 35 to rotate, so that the conversion disk 27 and the switching disk 26 rotate respectively, so that the air inside the heating tube 18 is transmitted downward through the air duct 47, and the power is cut off at both ends of the resistance wire 48, and the honeycomb block 25 is no longer heated, so that the heated air is continuously circulated through the air intake pipe 28, the middle tube 36, the heating tube 18, the air pump 17, the lower partition cover 16, the Chinese medicine plate 15 and the upper partition cover 13, so that the heat of the hot air is fully utilized to dry the Chinese medicine. When the temperature sensor detects that the internal air temperature has dropped, the motor 22 is turned on to make the moving frame 12 move to open the multiple exhaust slits 6 to discharge the internal air, and reheat a new part of the air for recycling again, thereby making full use of the hot air to dry the Chinese medicine and saving electricity.

[0046] Working principle: When in use, multiple Chinese medicine trays 15 are taken out by opening the sealed door 8, and the Chinese medicine to be dried is spread on the upper surface of the Chinese medicine tray 15, and the first protrusion 42 at one end of the Chinese medicine tray 15 is inserted into the installation groove 39, and the first protrusion 42 is clamped in the position of the inner groove 41 to stabilize the position of the Chinese medicine tray 15, and the second protrusion 43 at the other end of the Chinese medicine tray 15 is clamped in the position of the outer groove 40 to stabilize the position of the Chinese medicine tray 15 and reduce the vibration of the Chinese medicine tray 15. When the Chinese medicine tray 15 needs to be taken out, the second protrusion 43 at one end of the Chinese medicine tray 15 is lifted to separate the second protrusion 43 from the outer groove 40, and the first protrusion 42 slides out from the inside of the inner groove 41 to pull out the Chinese medicine tray 15, which has the effect of quickly installing and disassembling the Chinese medicine tray 15. When the medicine is added, the air pump 17 is started to generate negative pressure inside the heating tube 18, and the air enters the interior of the isolation box 5 through the air inlet slit 4, and enters the interior of the isolation chamber 24 through the exhaust slit 6 at the bottom of the isolation box 5. The air enters the interior of the air duct 50 through the air guide tube 34, and enters the interior of the heating tube 18 through the intermediate tube 36. The joint 49 is energized, and the resistance wire 48 starts to heat up to increase the temperature of the honeycomb block 25. Due to the effect of the switching disk 26, the air can only pass through the multiple heating holes 46 inside the honeycomb block 25 to enter the bottom of the heating tube 18. After passing through the bottom air pump 17 and the connecting pipe, the heated air has entered the interior of the lower partition cover 16. By rotating the conversion disk 27, the two ends of the air duct 50 are aligned with the air inlet pipe 28 and the intermediate tube 36 respectively, so that the upper partition cover The air at the top of 13 can enter the interior of the heating cylinder 18 through the air inlet pipe 28, achieving the effect of drying the Chinese medicine with two air circulation paths. The air is heated through the air holes on the top of the lower partition cover 16 to squeeze the room temperature air inside the drying chamber 23 upward. Since the multiple exhaust slits 6 on the top of the shell 1 are opened at this time, the room temperature air is discharged through the exhaust slits 6. The temperature sensor detects the rise in the air temperature inside the shell 1 and sends an electrical signal to the controller. The controller controls the motor 22 to rotate, driving the threaded rod 19 to rotate so that the motion block 20 moves back and forth, pushing the linkage plate 21 and the motion frame 12 to slide, thereby realizing the relative sliding between the motion frame 12 and the multiple exhaust slits 6, thereby controlling the opening and closing of the multiple exhaust slits 6, closing the multiple exhaust slits 6, and making the drying chamber 23 dry. The hot air inside the Chinese medicine plate 15 passes through the multiple drying holes 45 on the Chinese medicine plate 15, thereby taking away the moisture inside the Chinese medicine. Due to the oblique installation of the Chinese medicine plate 15, part of the hot air that cannot pass through the drying holes 45 floats upward along the bottom of the Chinese medicine plate 15, and the hot air continues to heat the Chinese medicine plate 15 above through the multiple air guide tubes 44, thereby accelerating the air flow and improving the drying efficiency. After closing the multiple exhaust slits 6, the movement of the linkage plate 21 drives the mounting frame 32, the linkage frame 33 and the branch rod to move, respectively pushing the first rotating plate 29 and the second rotating plate 35 to rotate, so that the conversion plate 27 and the switching plate 26 rotate respectively, so that the air inside the heating cylinder 18 is transmitted downward through the air duct 47, and the two ends of the resistance wire 48 are powered off, and the honeycomb block 25 is no longer heated.The heated air is made to circulate continuously through the air inlet pipe 28, the middle pipe 36, the heating cylinder 18, the air pump 17, the lower partition cover 16, the Chinese medicine plate 15 and the upper partition cover 13, making full use of the heat of the hot air to dry the Chinese medicine. When the temperature sensor detects that the internal air temperature drops, the motor 22 is turned on to make the moving frame 12 move to open multiple exhaust slits 6 to exhaust the internal air, and a new part of the air is reheated and recycled again, which has the effect of making full use of the hot air to dry the Chinese medicine and saving electricity.
