[0002] Traditional Chinese medicine decoction machines are commonly used in TCM clinics and pharmacies. They are devices that can decoct and package Chinese medicines in accordance with TCM standards and regulations. They have multiple functions, such as increasing sales, preventing prescriptions from being leaked, and making it more convenient for patients to take their medicines.

[0003] For example, the utility model disclosed in announcement number CN219354683U discloses a decoction machine, including a decoction pot with open upper and lower ends. The upper and lower ends of the decoction pot are respectively provided with an upper cover and a lower cover to seal them. A rotating shaft is provided on the upper cover. A stirring blade is provided at the lower end of the rotating shaft, and a fan blade is provided at the upper end of the rotating shaft. The fan blade generates a downward airflow when it rotates, which, together with the stirring action of the stirring blade, can accelerate the cooling of the Chinese medicine. This utility model, by providing an upper cover at the top of the decoction pot, a rotating shaft on the upper cover, a stirring blade at the lower end of the rotating shaft, and a fan blade at the upper end of the rotating shaft, generates a downward airflow when the fan blade rotates with the rotating shaft, which, together with the stirring action of the stirring blade, can accelerate the cooling of the Chinese medicine.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 1-6 As shown, the present invention proposes a condensation circulation and recovery structure in the pot of a decoction machine, which includes a frame 1 and a pot body 2 installed on the inner top wall of the frame 1. The upper surface of the frame 1 is hinged with a pot lid 3 covering the opening of the pot body 2, and a set of connectors 9 are fixedly connected to the outer surface of the pot lid 3.

[0036] The inner wall of the pot lid 3 is equipped with a condenser for condensing the liquid vapor, and the liquid inlet and liquid outlet of the condenser are respectively connected to a set of connectors 9.

[0037] The inner bottom wall of the frame 1 is provided with a circulating conveyor 7 for circulating cooling and conveying the condensate in the condenser;

[0038] The circulating conveying component 7 includes a heat dissipation chamber 72 fixedly connected to the bottom wall of the frame 1, and a first pump body 73 is fixedly installed on one side of the heat dissipation chamber 72. The liquid inlet end of the first pump body 73 is connected to a liquid extraction pipe 74 that is connected to one of the connectors 9 and passes through the frame 1. The liquid outlet end of the first pump body 73 is connected to a cooling pipe 75 that passes through and extends into the inside of the heat dissipation chamber 72 and transports and cools the condensate. The liquid outlet end of the cooling pipe 75 is connected to a return pipe 77 that passes through the heat dissipation chamber 72 and is connected to another connector 9.

[0039] In this invention, the condenser on the pot lid 3, in conjunction with the circulating conveyor 7, transports and cools the condensed material inside the condenser. This allows the condenser to condense the hot steam rising inside the pot body 2, enabling the condensed and liquefied medicine to drip back into the pot body 2. This reduces the emission of hot steam, decreases the volatilization of the medicine, reduces the impact of hot steam on the surrounding environment, and improves the decoction effect of the decoction machine.

[0040] It should be noted that one side of the pot lid 3 is also fixedly connected to the mounting joint 9 and has an exhaust pipe 10 extending from the back of the frame 1 through the inner top wall of the frame 1. An electric valve is installed at the connection between the exhaust pipe 10 and the pot lid 3. The exhaust pipe 10 helps to discharge steam to balance the pressure of the pot body 2. When the pot body 2 is decocting medicine, the electric valve on the exhaust pipe 10 is opened to discharge the steam that has not been condensed by the condenser, so as to prevent the pressure inside the pot body 2 from being too high.

[0041] The liquid extraction pipe 74 is connected to the liquid outlet end of the condenser pipe 6 on the same connector 9, and the return pipe 77 is connected to the liquid inlet end of the condenser pipe 6 on the same connector 9. This allows the first pump body 73 to pump the condensate in the condenser pipe 6, which is then cooled by the cooling pipe 75 and then transported back to the condenser pipe 6 through the return pipe 77.

[0042] In an optional embodiment, the condenser includes a baffle 5 and a guide plate 8 that are fixedly connected to the inner wall of the pot lid 3, and the guide plate 8 covers the outside of the baffle 5. A condenser tube 6 is fixedly connected to the outer surface of the baffle 5 and the inner wall of the pot lid 3. The liquid inlet end of the condenser tube 6 is connected to one of the connectors 9, and its liquid outlet end is connected to the other connector 9.

[0043] It should be noted that the baffle 5 is a cone shape that is narrow at the front and wide at the back, and both the baffle 5 and the guide plate 8 are metal plates, which allows the baffle 5 to block the hot steam and to better guide the cooled and condensed liquid back into the pot body 2 through the baffle 5. The guide plate 8 is a cone shape that is wide at the front and narrow at the back, which allows the guide plate 8 to act like a cover to guide the rising hot steam to the baffle 5 and the condenser pipe 6.

[0044] The condenser tube 6 has a conical spiral shape at one end on the baffle 5 and a spiral shape at the other end on the inner wall of the lid 3, which can increase the contact area between the part of the condenser tube 6 on the baffle 5 and the part on the inner wall of the lid 3 and the hot steam.

[0045] In this embodiment, the baffle 5, condenser 6 and guide plate 8 located on the pot lid 3 can better guide the hot steam to the baffle 5 and condenser 6 for condensation and liquefaction. The liquefied hot steam then flows back into the pot body 2, thereby reducing the emission of hot steam and improving the condensation and liquefaction effect of the hot steam.

[0046] In an optional embodiment, a plurality of sets of first heat sinks 76 are fixedly installed on the cooling pipe 75, and the heat-absorbing end of the first heat sink 76 penetrates and extends into the pipe wall of the cooling pipe 75. The end of the cooling pipe 75 located inside the heat dissipation chamber 72 is serpentine to increase the path of the coolant flowing through the cooling pipe 75. The plurality of sets of first heat sinks 76 are equidistantly distributed on the cooling pipe 75, and each set of first heat sinks 76 is equidistantly distributed in a ring, so that the plurality of equidistantly distributed and annularly distributed first heat sinks 76 conduct heat to the coolant flowing through the cooling pipe 75. The liquid extraction pipe 74 and the return pipe 77 are both flexible hoses so that the liquid extraction pipe 74 and the return pipe 77 do not interfere with the opening and closing of the pot lid 3.

[0047] The inner bottom wall of the frame 1 is equipped with a cooling component for dissipating heat and reducing the temperature of the cooling pipe 75.

[0048] In this embodiment, the coolant during the circulation process can be cooled by the serpentine distribution of the cooling pipes 75 and the several sets of first heat sinks 76 located on the cooling pipes 75.

[0049] In an optional embodiment, the cooling assembly includes a mounting cylinder 78 fixedly connected to the upper end of the heat dissipation chamber 72, and a fan 79 fixedly installed inside the mounting cylinder 78. A set of air guide chambers 710 are fixedly connected to the inner top wall of the heat dissipation chamber 72, and a liquid guide chamber 711 located between the set of air guide chambers 710 is fixedly connected to the inner top wall of the heat dissipation chamber 72. The outer surface of the lower end of the mounting cylinder 78 is connected to the upper surface of the air guide chamber 710 through a pipe. A liquid storage chamber 71 is fixedly connected to the upper end of the frame 1, and a second pump body 712 is fixedly installed at the upper end of the liquid storage chamber 71. The liquid outlet end of the second pump body 712 is connected to a drain pipe 714 that penetrates the heat dissipation chamber 72 and is connected to the liquid guide chamber 711, while the liquid inlet end of the second pump body 712 is connected to a supply pipe 713 that is connected to the lower part of the liquid storage chamber 71.

[0050] In this embodiment, the coolant during the circulation process can be cooled by the serpentine distribution of the cooling pipes 75 and the several sets of first heat sinks 76 located on the cooling pipes 75.

[0051] It should be noted that the lower surface of the liquid guiding chamber 711 is connected to several equally spaced nozzles. The cooling water flow drawn by the second pump body 712 is delivered through the liquid guiding chamber 711 and then sprayed out through the several nozzles. The lower surface of a set of air guiding chambers 710 is provided with several equally spaced air outlets. The air blown by the fan 79 is guided through the set of air guiding chambers 710 and then discharged into the heat dissipation chamber 72 through the several air outlets. The sprayed cooling water flow and the blown air flow cool the outer wall of the cooling pipe 75 and the heat dissipation end of the first heat dissipation fin 76.

[0052] Both cooling pipe 75 and heat dissipation pipe 715 are metal pipes.

[0053] In an optional embodiment, the cooling assembly further includes an air duct 717 fixedly connected to the back of the heat dissipation chamber 72, an air guide shroud 718 fixedly connected to the back of the liquid storage chamber 71, and the rear end of the air guide shroud 718 connected to the air duct 717. A plurality of heat dissipation pipes 715 are fixedly connected to the inner wall of the liquid storage chamber 71 and are connected to the front and rear side walls of the inner cavity. A plurality of second heat dissipation fins 716 are fixedly connected to each heat dissipation pipe 715 and are distributed in annularly at equal intervals. The heat dissipation end of the second heat dissipation fin 716 penetrates through and extends into the pipe wall of the heat dissipation pipe 715.

[0054] In this embodiment, the water flow and air flow delivered to the heat dissipation chamber 72 by the air guide chamber 710 and the liquid guide chamber 711 can accelerate the cooling rate of the coolant by the cooling pipe 75, thereby improving the condensation effect of the condenser pipe 6 on the hot steam. The air guide pipe 717 and the air guide cover 718 guide the air to the heat dissipation pipe 715 of the liquid storage chamber 71, which can dissipate heat from the water flowing back into the liquid storage chamber 71 again, thereby further improving the cooling effect of the coolant.

[0055] It should be noted that one side of the lower end of the heat dissipation chamber 72 is connected to one side of the upper end of the liquid storage chamber 71 through a pipe fitting. The inner top wall of the liquid storage chamber 71 is fixedly connected to a return chamber 719, and the lower surface of the return chamber 719 is provided with several return holes. One side of the return chamber 719 is connected to the pipe fitting between the heat dissipation chamber 72 and the liquid storage chamber 71, so that the water flow for spraying cooling in the heat dissipation chamber 72 can be guided to the return chamber 719 through the pipe fitting, and then flow into the liquid storage chamber 71 through the return chamber 719. During the process of flowing into the liquid storage chamber 71, it can be cooled by several heat dissipation pipes 715 and the second heat dissipation fin 716.

[0056] The back of the liquid storage tank 71 is fixedly connected to a liquid injection port that penetrates the back of the frame 1, and a valve is installed on the liquid injection port for the operator to open the valve and inject supplemental cooling water into the liquid storage tank 71 through the liquid injection port.

[0057] The frame 1 is equipped with a controller 4 for controlling the heating elements of the pot body 2 and the electrical components in the circulating conveyor 7. The control method of this utility model is automatic control through the controller 4. The control circuit of the controller 4 can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. However, this utility model is mainly used to protect the mechanical structure, so the control method and circuit connection and other technical means will not be described in detail.

[0058] The working principle in the above embodiments is as follows:

[0059] Steam condensation and recovery cycle inside the pot: When decocting medicine, a large amount of hot steam is generated inside the pot 2. When the pot lid 3 is closed, the steam rises and encounters the guide plate 8. Since the guide plate 8 is a "conical shape that is wide at the front and narrow at the back", it acts like a cover, effectively collecting and guiding the scattered rising steam to the baffle 5 located in the center and the condenser tube 6 wrapped around the baffle 5 and the inner wall of the pot lid 3. Both the baffle 5 and the guide plate 8 are made of metal and are good heat conductors. Their own temperature is lower than that of the steam. When the steam comes into contact with their surface, preliminary condensation will occur, and it will liquefy into water droplets.

[0060] More importantly, the condenser tube 6 contains a low-temperature coolant. The condenser tube 6 is designed in a conical spiral shape on the baffle 5 and in a spiral shape on the inner wall of the pot lid 3. This structure greatly increases its contact area with steam. When the hot steam comes into contact with the cold outer wall of the condenser tube 6, it will quickly release heat and liquefy into liquid droplets.

[0061] Liquid reflux: The water droplets formed by condensation adhere to the surfaces of baffle 5, guide plate 8 and condenser tube 6. Since baffle 5 is a "conical shape that is narrow at the front and wide at the back", its inclined surface can naturally guide the condensate to flow downwards, and finally drip back into the liquid in the pot body 2 under the action of gravity, thus completing the recycling.

[0062] The key function of the baffle plate 8 is to prevent steam from diffusing directly to other areas of the pot lid without condensation, ensuring that most of the steam is "guided" to the condensation area. The conical design of the baffle plate 5 is not only to guide the backflow, but its shape also increases the contact surface area of ​​the steam.

[0063] External coolant forced cooling circulation

[0064] Loop path:

[0065] Coolant flows out from condenser 6 → liquid extraction pipe 74 → first pump body 73 → cooling pipe 75 → return pipe 77 → back to condenser 6;

[0066] Heat absorption and pumping: The coolant, which has absorbed heat from the steam in the boiler, has a higher temperature and flows out from the outlet of the condenser 6. It enters the pumping pipe 74 through a connector 9. The first pump body 73 works to pump this heated coolant into the cooling pipe 75.

[0067] Primary heat dissipation air cooling + water cooling: The cooling pipe 75 is located inside the heat dissipation chamber 72 and is designed in a serpentine shape to extend the flow path. When the fan 79 is started, it blows air into the air guide chamber 710 and blows it evenly to the cooling pipe 75 and the first heat dissipation fin 76 on it through the air outlet at the bottom. The heat dissipation fin greatly increases the heat dissipation area and accelerates the dissipation of heat into the air.

[0068] Meanwhile, the second pump body 712 draws low-temperature cooling water from the bottom of the liquid storage tank 71, pumps it into the liquid guide tank 711 through the liquid supply pipe 713, and sprays it downwards through the nozzle at the bottom. This cold water directly sprays onto the high-temperature cooling pipe 75 and the first heat sink 76, and carries away a large amount of heat through water evaporation and heat exchange. The cooled liquid flows out from the cooling pipe 75, and is transported back to the liquid inlet end of the condenser pipe 6 through the return pipe 77 and another connector 9, and starts to absorb the steam heat in the pot again.

[0069] Cooling water recovery and secondary heat dissipation:

[0070] The water used for spraying and cooling in the heat dissipation chamber 72 will be collected at the bottom of the chamber and flow back to the return chamber 719 above the inner wall of the liquid storage chamber 71 through the pipe. The water will be evenly sprayed into the liquid storage chamber 71 through the return hole at the bottom of the return chamber 719. At the same time, during the fall, the water flows through multiple heat dissipation pipes 715, which are equipped with second heat dissipation fins 716.

[0071] At this time, the air, which has already carried some heat, is drawn out from the heat dissipation chamber 72 through the air duct 717 and flows laterally through these heat dissipation pipes 715 under the guidance of the air duct 718. The air exchanges heat with the second heat dissipation fins 716 and performs secondary air cooling to dissipate heat on the falling water, further reducing its temperature and preparing it for the next water pumping and cooling operation of the second pump body 712.

[0072] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
