[0026] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0027] Reference Figure 1 - Figure 3 The utility model discloses a Chinese medicine slice drying device, comprising a shell 1, a working groove 2 is provided on one side of the shell 1, a plurality of trays 3 for placing Chinese medicine slices are connected in the working groove 2, a heating mechanism 4 for drying Chinese medicine slices is provided on the top of the shell 1, and an air duct 10 for exhaust is provided at the bottom of the shell 1.

[0028] In this embodiment, the compressed Chinese herbal medicine slices are placed in the placement groove 8 of the tray 3, and then the tray 3 is loaded into the working groove 2. After that, the box door is closed to seal the working groove 2 and the heating mechanism 4 can be started to operate the fan 41 to generate suction to suck the outside air into the through groove 5. After the air enters the through groove 5, it will contact the heating block 42. The air heated by the heating block 42 will enter the working groove 2 under the push of the fan 41 to take away the moisture of the Chinese herbal medicine slices, thereby drying the Chinese herbal medicine slices. Then the hot air is discharged through the air duct 10 at the bottom of the shell 1.

[0029] In a further preferred embodiment of the present invention, Figure 2 As shown, the heating mechanism 4 includes a fan 41, a heating block 42 and a partition 43. A through slot 5 is provided on one side of the top of the shell 1. The middle of the through slot 5 is connected to the working slot 2. The fan 41 is provided in the middle of the through slot 5. Partitions 43 are fixedly connected at two openings of the through slot 5. A heating block 42 is provided on one side of the partition 43 close to the fan 41.

[0030] In this embodiment, because the volume of hot air is large, its density is smaller than that of normal temperature air, which will cause the hot air to be squeezed by normal temperature air and flow upward. Therefore, if the heating mechanism 4 used for drying Chinese herbal medicines is set at the bottom of the working tank 2, the hot air will flow upward rapidly under the action of the fan 41, resulting in too short a contact time between the hot air and the Chinese herbal medicines, thus affecting the drying efficiency. Therefore, a heating mechanism is provided at the top of the working tank 2, so that the hot air blown out by the fan 41 will flow downward under the action of inertia, and when the inertia of the hot air disappears, it will return to the top of the working tank 2 due to the squeezing of normal temperature air. As more and more hot air accumulates at the top of the working tank 2, the hot air can squeeze the normal temperature air out of the working tank 2, thereby extending the time that the hot air remains in the working tank 2, so that the hot air can better dry the Chinese herbal medicines, improve the energy utilization efficiency, and accelerate the drying of the Chinese herbal medicines.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the heating block 42 includes two power posts 421 and a plurality of heating wires 422 . The two power posts 421 are respectively connected to the inner walls of both sides of the through slot 5 , and a plurality of heating wires 422 are arranged between the two power posts 421 .

[0032] In this embodiment, when air enters the through groove 5, the air will contact the heating block 42 and take away the temperature of the surface of the heating block 42, and the air that takes away the temperature of the surface of the heating block 42 will also heat up, thereby increasing the temperature of the air. Because the fan 41 is running, the air flows faster, so the contact time between the air and the heating block 42 is too short, resulting in a poor heating effect of the air. Therefore, a plurality of heating wires 422 are provided in the heating block 42 to effectively increase the contact area with the air. Therefore, when the two power poles 421 are respectively electrically connected to the positive and negative poles of the power supply so that the plurality of heating wires 422 generate heat, the air can heat up rapidly, which can improve the drying efficiency of the Chinese herbal medicine slices.

[0033] In a further preferred embodiment of the present invention, Figure 1 As shown, the outer wall of the partition plate 43 is provided with a plurality of through holes 6 for air circulation, and filter elements 7 for filtering dust are arranged in the through holes 6 .

[0034] In this embodiment, when the fan 41 is running, negative pressure will be generated in the through groove 5 to suck in the outside air, and the outside air will inevitably contain small particles such as dust, so these small particles will enter the working groove 2 along with the air and contaminate the Chinese herbal medicines. Therefore, a filter element 7 is provided in the through hole 6 to filter the dust particles and effectively prevent the Chinese herbal medicines from being contaminated.

[0035] In a further preferred embodiment of the present invention, Figure 3 As shown, a placement groove 8 is provided on the top of the tray 3 , and a plurality of meshes communicating with the placement groove 8 are provided on the bottom of the tray 3 .

[0036] In this embodiment, because Chinese herbal medicines are placed in the tray 3, the airflow blown out by the fan 41 is blocked, which interferes with the flow of the airflow, causing the airflow to accumulate in the tray 3 on the top layer of the working tank 2, and then slowly flow downward until it fills the entire working tank 2. When the airflow accumulates at the top of the working tank 2, the air pressure at the top of the working tank 2 will increase, thereby weakening the air delivery efficiency of the fan 41 and affecting the drying speed of the Chinese herbal medicines. Therefore, a mesh is provided in the tray 3, which can allow the airflow blocked by the Chinese herbal medicines to flow downward along the mesh, thereby reducing the air pressure at the top of the working tank 2 to avoid slowing down the drying efficiency.

[0037] In a further preferred embodiment of the present invention, Figure 2 As shown, the inner bottom wall of the working groove 2 is provided with a guide groove 9 connected with the air channel 10 , and the guide groove 9 is in contact with the inner side wall of the working groove 2 .

[0038] In this embodiment, when hot air is blown into the working tank 2 by the fan 41, the temperature difference between the hot air and the inner wall of the working tank 2 is too large, so condensed water will be generated. If the condensed water cannot be effectively discharged, the humidity in the working tank 2 will increase, affecting the drying efficiency of the Chinese herbal medicine slices. Therefore, a guide groove 9 is provided at the bottom of the working tank 2, so that the condensed water will fall into the guide groove 9 when sliding down the inner wall of the working tank 2, and then be discharged along the connection between the guide groove 9 and the airway 10, effectively avoiding the increase of humidity in the working tank 2.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
