[Further details about the through-hole and the device are not provided in the original text.] A suction port 23 is provided. The suction port 23 and the through port 26 are symmetrically arranged on both sides of the top of each partition plate 28. Each suction port 23 can communicate with the end of the suction pipe 22, and each through port 26 can communicate with the end of the air intake pipe 25. The hollow device 21, the suction port 23 and the through port 26 are all electrically connected to the corresponding power supply. The model of the hollow device 21 is the same as the device of the same name used in the prior art (publication number: CN220871268U). The model of the pulse air intake device 24 is the same as the structural model of the same name used in the prior art (publication number: CN220871268U). This is the prior art, so it will not be described in detail here.

[0031] like Figure 3 , Figure 4 and Figure 5 As shown, the drying structure is set inside the cavity of the machine body 20 for drying medicinal materials. The drying structure includes: a heating pipe 30, a placement plate 32, and a bottom clamp 36. The heating pipe 30 is fixedly connected to the top of each partition plate 28. The placement plate 32 is clamped to the top of the heating pipe 30. The bottom clamp 36 is fixedly connected to the bottom of the placement plate 32. The bottom clamp 36 can be clamped to the heating pipe 30. Medicinal materials can be placed on the top of the placement plate 32.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the heat outlet pipe 30 is an L-shaped rectangular tube. Rectangular slots are formed on the top and front wall of the heat outlet pipe 30. The rear wall of each heat outlet pipe 30 can simultaneously communicate with the hot air structure 27. The placement plate 32 is a rectangular plate, and the base plate 36 is a rectangular rod. The bottom of each placement plate 32 is symmetrically provided with the same base plate 36. The heat outlet pipe 30 can be snapped into each set of symmetrical base plates 36. The drying structure also includes a drain hole 33, a dividing rod 34, and a protective edge 35. The drain hole 33 is formed through the top of the placement plate 32, and the dividing rod 34... Rod 34 is fixedly connected to the top of the placement plate 32, and edge guard 35 is also fixedly connected to the top of the placement plate 32. The drain hole 33 is a circular hole, and multiple drain holes 33 are evenly opened on the top of the placement plate 32. The edge guard 35 is a rectangular frame, and the outer wall dimension of the edge guard 35 is the same as the top dimension of the placement plate 32. The same drain holes 33 are also opened on the wall of the edge guard 35. The branch rod 34 is a rod with a semi-circular cross section, and multiple branch rods 34 are evenly arranged on the top of the placement plate 32. Each branch rod 34 is located between adjacent drain holes 33.

[0033] In practical use, first place the herbs to be dried on the top of the placement plate 32, then align the symmetrical locking bottom 36 and the heating pipe 30 at the bottom of the placement plate 32 and slide them to the top of the partition plate 28. At this time, the symmetrical locking bottom 36 will engage with the heating pipe 30. After the placement plate 32 slides to the innermost part of the cavity of the machine body 20, stop pushing the placement plate 32. Then close the door 29 at the corresponding placement plate 32. The remaining placement plates 32 are operated in the same way. After all the herbs are placed, turn on the power of the device. First, the hollow device 21 will evacuate the chambers separated by each partition plate 28 to make each chamber hollow. After the evacuation is completed, start the pulse air intake device 24. The pulse air intake device 24 can inject air into the chambers formed by each partition plate 28 through the air intake pipe 25. At the same time, the hot air structure 27 can release heat through the grooves on the wall of the heating pipe 30, thereby drying the herbs on the top of the placement plate 32.

[0034] In summary, by setting up a drying structure, a high-quality drying effect can be achieved. When the drying structure moves the medicinal materials for drying, the medicinal materials will be located in the center of each chamber. Furthermore, by setting up the perforation 33, the medicinal materials located below can also receive the same heat. Therefore, compared with the existing technology, the drying quality of this solution is higher.

[0035] like Figure 4 and Figure 5As shown, the wall surface of the heat outlet pipe 30 is provided with a snap-fit ​​structure, which includes a snap-fit ​​groove 31, an adapter groove 37, a snap-fit ​​plate 38, and a snap-fit ​​block 39. The snap-fit ​​groove 31 is symmetrically opened on both sides of the wall surface of each heat outlet pipe 30. The adapter groove 37 is opened on the side wall surface of each snap-fit ​​bottom 36. The snap-fit ​​plate 38 is fixedly connected in each adapter groove 37. The snap-fit ​​block 39 is fixedly connected to the side wall surface of each snap-fit ​​plate 38. The snap-fit ​​groove 31 is a semi-circular groove that can fit the size of the snap-fit ​​block 39. The adapter groove 37 is a rectangular slot. The snap-fit ​​plate 38 is a rectangular plate with a gap in the adapter groove 37. The snap-fit ​​block 39 on the wall surface of each symmetrical snap-fit ​​bottom 36 can be snapped into the snap-fit ​​groove 31 on both sides of the heat outlet pipe 30 at the same time.

[0036] In practical use, when the symmetrical card bottom 36 slides along the heat outlet pipe 30, the card plate 38 can bend into the adapter groove 37 due to the contact with the side wall of the heat outlet pipe 30. At this time, the arc surface of the card block 39 will move along the side wall of the heat outlet pipe 30. When the card block 39 moves to the card groove 31, the card plate 38 will re-fit with the side wall of the heat outlet pipe 30 because the card block 39 enters the card groove 31.

[0037] In summary, by setting up a snap-fit ​​structure, the position of the placement plate 32 can be automatically fixed, thereby preventing the placement plate 32 from moving during the drying process of medicinal materials and causing the medicinal materials to tip over, thus improving the stability of the device during operation.

[0038] Working principle: First, place the herbs to be dried on top of the placement plate 32. Then, align the symmetrical locking base 36 at the bottom of the placement plate 32 with the heating pipe 30 and slide it to the top of the partition plate 28. At this time, the symmetrical locking base 36 will engage with the heating pipe 30. After the placement plate 32 slides to the innermost part of the machine body 20 cavity, stop pushing the placement plate 32. Then, close the door 29 at the corresponding placement plate 32. The remaining placement plates 32 are operated in the same way. After all the herbs are placed, turn on the power of the device. First, the hollow device 21 will... The chambers separated by each partition plate 28 are evacuated to make each chamber hollow. After evacuation, the pulsating air intake device 24 is activated. The pulsating air intake device 24 can inject air into the chambers formed by each partition plate 28 through the air intake pipe 25. At the same time, the hot air structure 27 can release heat through the grooves on the wall of the heat outlet pipe 30 to dry the medicinal materials on the top of the placement plate 32. After the medicinal materials are dried, the power of the device is turned off, the door 29 is flipped open, and the placement plate 32 is pulled out from the top of each heat outlet pipe 30.

[0039] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
