[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a microwave sterilization device for Chinese herbal medicines, comprising a sterilization box 1. The sterilization principle of the sterilization box 1 is consistent with the principle in the existing patent mentioned in the background technology, wherein an air outlet 11 is opened on the top of the sterilization box 1, and the air outlet 11 is used to discharge water vapor. An electric turntable 12 is arranged at the bottom of the sterilization box 1, and a tray rack 13 is detachably connected to the electric turntable 12. When the electric turntable 12 rotates, the tray rack 13 is driven to rotate, and the tray rack 13 is used to place Chinese herbal medicines.

[0024] In the present technical solution, the tray rack 13 includes a placement plate 131 and a support column 132. The bottom of the support column 132 is fixedly connected to the middle of the upper end surface of the placement plate 131. The middle of the lower end surface of the placement plate 131 is provided with a slot 1311 that is plugged into and cooperates with the support column 132 and the top of the electric turntable 12. In other words, a tray rack 13 is composed of multiple placement plates 131 plugged in from top to bottom through the support column 132. Hanging rods 2 are horizontally swingably connected on both sides of the sterilization box 1. Swinging here means that the hanging rod 2 can be rotated to a state of being approximately in contact with the inner wall of the sterilization box 1, but can only be rotated to a state of being approximately vertical to the inner wall of the sterilization box 1. Specifically, hinge seats 14 hingedly connected to one end of the hanging rod 2 are welded on both sides of the sterilization box 1, and a baffle 141 for limiting the rotation of the hanging rod 2 is welded on one side of the hinge seat 14. The baffle 141 serves to limit the rotation of the hanging rod 2. It should be noted that the hinge seats 14 and baffles 141 on the two side walls of the sterilization box 1 are circumferentially uniformly distributed relative to the axis of the electric turntable 12.

[0025] When the hanging rod 2 is unfolded, its free end will be located above the placement tray 131. The hanging rod 2 is arranged up and down along the inner cavity of the sterilization box 1. One hanging rod 2 corresponds to one placement tray 131. The free end of the hanging rod 2 is rotatably connected to a roller 3. The outer peripheral wall of the roller 3 is fixedly connected to a circle of lever 4. When the roller 3 is located in the placement tray 131, the lever 4 will be inserted between the Chinese herbal medicine pieces. When the entire tray rack 13 rotates, the Chinese herbal medicine pieces will push the roller 3 to rotate, and the lever 4 will stir the Chinese herbal medicine pieces. The lever 4 is arranged along the axis direction of the roller 3, and a rubber coating is provided on the lever 4. The rubber coating can effectively protect the Chinese herbal medicine pieces and avoid damaging the Chinese herbal medicine pieces.

[0026] In this embodiment, the suspension rods 2 arranged up and down are fixedly connected by a connecting rod 5, that is, the suspension rods 2 on the same side can rotate at the same time, thereby improving the convenience of folding control of the suspension rods 2.

[0027] In this embodiment, a polygonal docking joint 6 is welded to the top of the pillar 132 and the electric turntable 12, and the slot 1311 is adapted to the polygonal docking joint 6. When the electric turntable 12 rotates, the above-mentioned adaptation structure can effectively drive the entire tray rack 13 to rotate.

[0028] Furthermore, a suction cup 7 is embedded in the card slot 1311, and a mirror panel 61 is bonded to the upper end surface of the polygonal joint 6. The setting of the suction cup 7 ensures that the Chinese herbal medicines on the tray rack 13 will not loosen or detach from the electric turntable 12 when being stirred, thereby improving the stability of the stirring of the Chinese herbal medicines.

[0029] A vent valve 8 is provided on the outer peripheral wall of the polygonal joint 6, and an air duct 611 is opened in the middle of the mirror panel 61. The air duct 611 is connected to the vent valve 8. The vent valve 8 is a tapered thread structure. When the vent valve 8 is manually loosened, the external gas enters the air duct 611. At this time, the tray rack 13 can be easily disassembled, and the Chinese herbal medicine pieces have the advantage of being more convenient and quick to unload after sterilization.

[0030] Working principle: 1. Loading: Place the Chinese herbal medicine pieces on each placement tray 131, then stack the placement trays 131 carrying the Chinese herbal medicine pieces and plug them together to form a complete tray rack 13, and place the tray rack 13 on the electric turntable 12 in the sterilization box 1. At this time, the loading process of the Chinese herbal medicine pieces is completed.

[0031] 2. Microwave sterilization: manually rotate the suspension rod 2 so that the roller 3 thereon enters above the adjacent placement tray 131. After the suspension rod 2 is unfolded, it is limited by the baffle 141. The outer door of the sterilization box 1 is closed, and the microwave equipment in the sterilization box 1 is started to heat the Chinese herbal medicines. At the same time, the electric turntable 12 rotates. At this time, the entire tray rack 13 rotates. Due to the limiting effect of the baffle 141, the suspension rod 2 cannot be pushed. The Chinese herbal medicines in the placement tray 131 will push the roller 3 to rotate through the lever 4. When the roller 3 rotates, the lever 4 is used to stir the Chinese herbal medicines to achieve stirring microwave sterilization. The water vapor in the Chinese herbal medicines will be quickly discharged through the air outlet 11.

[0032] 3. Unloading: After turning off the power, open the outer door, then manually loosen the air release valve 8 near the electric turntable 12. At this time, the negative pressure in the suction cup 7 disappears, and then manually swing the suspension rod 2 close to the inner wall of the sterilization box 1. Finally, remove the tray rack 13 as a whole, and then loosen the remaining air release valves 8 one by one to remove each placement tray 131, which is convenient for transferring the sterilized Chinese herbal medicine pieces.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
