Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine production equipment technology, and in particular to a decoction pot brushing structure. Background Technology

[0002] In traditional Chinese medicine production, herbs are decocted using a decoction pot. The decoction pot consists of an outer pot, an inner pot housed within the outer pot, and a lid covering the inner pot. The inner pot has an outward-curling edge that covers the upper part of the outer pot. The outer pot also has an outward-curling edge, and the lid has pinching protrusions. The decoction pot is designed for reuse; it needs to be cleaned after each use before being used again. Current methods involve pouring out the dregs and liquid, then directly transferring the herbs to a cleaning device. This leaves dregs on both the inner and outer pots, easily causing blockages in the drain pipes during cleaning. Utility Model Content

[0003] The present invention aims to provide a decoction pot inner pot cleaning structure that can remove residual medicinal residue from the inner pot, in order to solve the problem that medicinal residue entering the cleaning process can easily cause pipe blockage.

In use, the robotic arm holds the decoction pot and flips it over to guide the dregs into the dregs guide hopper. Then, the inner pot is fitted onto the inner pot brush of the inner pot brush cavity. The switch structure of the inner pot brush cavity drives the inner pot brush cavity cover to close, causing the inner pot brush of the inner pot brush cavity to rotate to brush the inside of the inner pot, and the outer pot brush of the inner pot brush cavity to rotate to brush the outside of the inner pot.

[0005] Preferably, the dregs guide hopper is located in front of and integrated with the inner pot brushing cavity. When transferring the inner pot to the inner pot brushing cavity, the inner pot remains above the dregs guide hopper and the inner pot brushing cavity. This prevents dregs from falling into unintended areas and causing environmental pollution during the transfer process.

[0006] Preferably, the top of the inner pot cleaning cavity is open, forming an upper opening. The upper end of the front side wall of the inner pot cleaning cavity has a side opening. The upper opening and the side opening communicate with each other.

This facilitates the movement of the decoction pot into and out of the inner pot cleaning cavity.

[0007] Preferably, the inner pot has an inwardly folded edge, and the inner pot brushing cavity is provided with several inner pot brushing cavity limiting rods and several inner pot fixing structures. An inner pot brushing cavity supporting block is provided on one side of the space enclosed by the inner pot brushing cavity limiting rods to support the inner pot. The inner pot fixing structures are used to press the inwardly folded edge of the inner pot onto the inner pot brushing cavity supporting block. In use, the inner pot, with the outer pot fitted inside, is supported on the inner pot brushing cavity supporting block. The inner pot fixing structures fix the outwardly folded edge of the inner pot to prevent it from moving upwards. Then, a robotic arm lifts up the outer pot and removes it.

[0008] Preferably, the inner pot brushing chamber is equipped with an inner pot brushing chamber discharge port. The lower end of the inner pot brush is located inside the discharge port, which connects to the inner pot brushing chamber. The inner diameter of the discharge port is larger than the inner diameter of the outer pot. The inner pot brushing chamber support block extends into the discharge port. The inner pot fixing structure and the inner pot brushing chamber limiting rod are installed outside the discharge port. During brushing, the downward projection of the inner pot's internal space is entirely within the discharge port, ensuring that the brushed-off dregs fall completely into the dregs box.
