Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine extraction machinery, and in particular to a traditional Chinese medicine extraction machine with multiple output ports. Background Technology

[0002] A traditional Chinese medicine (TCM) decoction machine is a device used to decoct Chinese medicinal herbs. It is typically found in hospitals and pharmacies. Referring to patent publication number 211196711U, a high-pressure decoction and packaging machine is disclosed, which has the function of decocting herbs and dispensing the liquid. However, many TCMs are currently not taken as liquids but as pills or pastes. Referring to patent publication number 111846480A, a TCM paste sealing machine, and patent publication number 213852056U, a TCM pill-making machine, the current method used in hospital pharmacies to prepare pastes and pills involves first decocting the herbs to obtain a liquid, and then manually pouring it into the paste or pill machine. It can be seen that pills and pastes are all secondary processing based on liquids. However, currently, the equipment for preparing liquids, pastes, and pills is used independently and lacks interoperability. Utility Model Content

[0026] Reference Figures 1 to 5 A Chinese herbal medicine extraction machine with multiple output ports, comprising:

[0027] The main body 10 of the medicine machine includes a decoction pot 40, a first heater for heating the decoction pot 40, and a liquid outlet or liquid packaging device 50 disposed on the main body 10. The decoction pot 40 is provided with a liquid outlet pipe 70, and the liquid outlet pipe 70 is provided with a main body 701 connected to the liquid outlet or liquid packaging device 50. The liquid outlet pipe 70 is also provided with at least one branch pipe, and the branch pipe is provided with a branch valve body. The main body 701 is provided with a main valve body 702.

[0028] When in use, the number of tubes is arranged according to the number of corresponding pellet making machines 20 or ointment making machines 30.

[0029] In this design, it is preferable that the branch pipes are two separate pipes, namely a first branch pipe 72 and a second branch pipe 73. The valve bodies are a first valve body 721 installed on the first branch pipe 72 and a second valve body 731 installed on the second branch pipe 73. This arrangement is intended to facilitate simultaneous connection of the pill-making machine 20 and the ointment-making machine 30. In use, it is preferable to connect the first branch pipe 72 to the pill-making machine 20 and the second branch pipe 73 to the ointment-making machine 30. The user puts the medicinal materials into the decoction pot 40 and adds a specified amount of water. When it is necessary to prepare an aqueous solution, the first valve body 721 and the second valve body 731 are closed, and the main valve body 702 is opened. The first heater decocts the medicinal materials placed in the decoction pot 40, and the decoction is then pumped into the liquid outlet or liquid packaging device 50 for packaging and storage by the liquid pump 71. When pills need to be prepared, the second valve 731 and the main valve 702 are closed, and the first valve 721 is opened. After the decoction in the decoction pot 40 is boiled, the liquid pump 71 transports the decoction through the first branch pipe 72 to the pill-making machine 20, thereby preparing pills. Similarly, when ointments need to be prepared, the second valve 731 is opened, and the first valve 721 and the main valve 702 are closed, allowing the prepared decoction to be fed into the third pot of the ointment-making machine 30, facilitating the ointment-making machine 30 to prepare the ointment. This solution organically connects the production equipment for aqueous solutions, pills, and ointments, thereby reducing the user's operational procedures, increasing the degree of automation, and significantly reducing the labor load in pharmacies and hospitals preparing traditional Chinese medicine products.

[0030] In this design, the main body 10 of the medicine machine is preferably provided with a front-opening accommodating cavity 11, and the decoction pot 40 is disposed in the accommodating cavity 11. The accommodating cavity 11 is provided with a pot lid 41 that can be movably covered to close the decoction pot 40, so that when preparing the medicine liquid, the decoction pot 40 is closed by the pot lid 41 to ensure the airtightness of the decoction process.

[0031] Considering that some medicinal materials need to be decocted separately and then added to the main decoction for mixing after decoction, it is preferable that the main body 10 of the medicine machine is also equipped with a pre-decoction pot 60 and a fourth heating element for heating the pre-decoction pot 60. The bottom of the pre-decoction pot 60 is provided with a pre-decoction pipe 61, which is fixed to the pot lid 41. The pre-decoction pipe 61 is equipped with a pre-decoction valve 62 or a pre-decoction liquid pump, so that the medicinal materials that need to be decocted separately are decocted through the pre-decoction pot 60 to form a pre-decoction liquid. After decoction, the pre-decoction valve 62 is opened to transport the pre-decoction liquid in the pre-decoction pot 60 to the decoction pot 40 for mixing with the decoction liquid in the decoction pot 40. If the height of the pre-decoction pot 60 is lower than that of the decoction pot 40, a pre-decoction liquid pump needs to be installed on the pre-decoction pipe 61. However, the cost of the pre-decoction liquid pump is relatively high. In order to save costs and optimize the structural layout, and to facilitate the addition of medicinal materials, cleaning and maintenance by users, it is preferable that the pre-decoction pot 60 is located on the top left side of the main body 10 of the medicine machine, the receiving cavity 11 is located on the bottom left side of the main body 10 of the medicine machine, and a packaging cavity 12 is provided on the right side of the front end face of the main body 10 of the medicine machine. The liquid packaging equipment 50 includes two mounting rollers 52 and a heat sealing machine 51 located below the mounting rollers 52. The mounting rollers 52 are located on the upper part of the packaging cavity 12, and the heat sealing machine 51 is located on the lower part of the packaging cavity 12. Located at the lower part of the packaging cavity 12, this structural optimization has several advantages: First, the pre-decoction pot 60 is located at the top of the decoction pot 40, allowing the pre-decoction liquid to be directly input into the decoction pot 40 by gravity. Second, the decoction pot 40 is located at the bottom, allowing the user to operate it from a higher position, making it easier to add herbs, clean the decoction pot 40, and observe the state of the liquid. Third, the liquid packaging device 50 is placed on the right side of the main body 10 of the medicine machine, while the pre-decoction pot 60 and the decoction pot 40 are placed on the left side of the main body 10, thereby reducing the overall height of the main body 10 of the medicine machine and making the operation more convenient for the user.

[0032] In this design, preferably, a first control panel 80 is provided on the front face of the main body 10 of the medicine machine, located between the pre-decoction pot body 60 and the accommodating cavity 11. A second control panel 81 is pivotally connected to the right edge of the main body 10 of the medicine machine. The second control panel 81 can swing relative to the packaging cavity 12 to cover the upper front end of the packaging cavity 12 and connect with the first control panel 80. This structure has two advantages: first, when the second panel covers the front face of the packaging cavity 12, it connects with the first control panel 80 to form a larger operating panel, making operation more convenient for the user and providing a more comfortable visual effect; second, it can cover the mounting roller 52, thereby avoiding direct contact with the packaging bag placed on the mounting roller 52. Further optimization is preferred, preferably, the second control panel 81 can only cover part of the front opening of the upper part of the packaging cavity 12, and a swinging upper sealing plate 82 is pivotally connected to the top of the main body 10 of the medicine machine. The upper sealing plate 82 can movably cover the other parts of the front opening of the upper part of the packaging cavity 12.

[0033] In this design, to facilitate cleaning of the decoction pot 40 and discharge of waste liquid from it, it is preferable that a drain pipe 74 is connected to the outlet pipe 70, and a drain port 75 connected to the drain pipe 74 is provided on the surface of the main body 10 of the medicine machine. A drain valve 741 is provided on the drain pipe 74. When cleaning and draining are required, the main valve, the first valve body 721 and the second valve body 731 are closed, and the drain valve 741 is opened, so that the waste liquid in the decoction pot 40 can be drained.

[0034] In this solution, considering that steam is generated during the decoction process, and the aroma of Chinese medicine in the steam is strong, the traditional method directly releases the aroma into the room, causing the smell of Chinese medicine to linger for a long time. Therefore, an optimization is made: preferably, when the pot lid 41 is placed on the decoction pot 40, it seals the decoction pot 40. The pot lid 41 is equipped with a pressure regulating valve, and the pressure regulating valve is equipped with a steam pipe 76 connected to the drain port 75. A steam valve 761 is installed on the steam pipe 76, and a cooling device 77 is installed on the steam pipe 76 in front of the steam valve 761. Through this solution, the steam generated during the decoction process in the decoction pot 40 is reduced. Once the steam reaches a certain pressure, it opens the pressure regulating valve and then flows along the steam pipe 76 to the drain outlet 75 for discharge. During the discharge process, the steam is condensed into liquid by the cooling device 77, thus avoiding the upward effect caused by steam discharge. At the same time, during the decoction process, the steam valve 761 can be left closed until a certain amount of steam is discharged and condensed into a certain amount of liquid before the steam valve 761 is opened for discharge, thus avoiding the phenomenon of external polluting air diversion. In this way, both steam and waste liquid can be discharged into the sewer or drain pipe through a drain outlet 75, avoiding the problem of steam being directly discharged into the room.

[0035] Further optimization involves using a condensing metal device 77 that is attached to the steam pipe 76. Since the overall steam volume is not large, using a condensing metal device for condensation is sufficient, eliminating the need for a dedicated refrigerant circulation system.

[0036] To further optimize the process and facilitate the movement of the decoction pot 40, a push plate 43 is preferably provided on the bottom surface of the accommodating cavity 11. A drive motor 44 is provided between the accommodating cavity 11 and the push plate 43 to push the push plate 43 outward from the accommodating cavity 11. The decoction pot 40 is fixedly mounted on the surface of the push plate 43. A heating chamber is provided on the push plate 43 located on the bottom surface of the decoction pot 40. The first heater is located in the heating chamber and its bottom is suspended. With this structure, firstly, the drive motor 44 pushes the push plate 43, thereby moving the decoction pot 40 in and out, thus eliminating the need for manual movement of the decoction pot 40. Secondly, the first heater is suspended in the heating chamber provided on the push plate 43, so that the force on the decoction pot 40 will not act on the first heater, thus protecting the first heater and making it less prone to damage. In this scheme, the drive motor 44 can be implemented in various ways. In the first embodiment, the drive motor 44 is a linear motor disposed on the inner wall of the accommodating cavity 11, and the output end of the linear motor directly abuts against the push plate 43, thereby pushing the push plate 43 out. In the second embodiment, the drive motor 44 is a rotary motor disposed at the bottom of the accommodating cavity 11, and a drive gear 441 is installed on the output end of the rotary motor. A rack 45 that meshes with the drive gear 441 is provided on the bottom surface of the push plate 43, and the push plate 43 is moved by the meshing action of the drive gear 441 and the rack 45. Preferably, a slide rail 111 is provided between the push plate 43 and the inner wall of the accommodating cavity 11 to reduce the resistance when the push plate 43 moves.

[0037] Further optimization involves installing a lifting motor within the accommodating cavity 11, with a lifting rod 42 at the bottom of the lifting motor. The pot lid 41 is fitted onto the lifting rod 42, and an extraction pressure plate 421 is installed at the bottom of the lifting rod 42. A counterweight 411 is installed on the pot lid 41. By installing the extraction pressure plate 421, during operation, the extraction pressure plate 421 reciprocates within the decoction pot 40, continuously squeezing the medicinal materials, thereby allowing the effective components in the medicinal materials to be extracted more fully. The counterweight 411 is used to firmly cover the pot lid 41 onto the decoction pot 40 when the lifting motor continuously drives the extraction pressure plate 421 to move within the decoction pot 40.

[0038] In this scheme, the main valve body 702, the first valve body 721, the second valve body 731 and the preheating valve body 62 are preferably solenoid valves, and the steam valve 761 and the drain valve 741 are manually operated plug valves.

[0039] In this embodiment, the main valve body 702 can also be directly installed on the liquid outlet tap or the liquid packaging device 50. In other embodiments, the main valve body 702 and the branch valve bodies can be integrated into a switching valve body. For example, the main valve body 702, the first valve body 721, and the second valve body 731 can be integrated into a solenoid four-way valve. The solenoid four-way valve includes one inlet and three outlets. The main pipe 701, the first branch pipe 72, and the second branch pipe 73 are respectively connected to the three outlets of the solenoid four-way valve, and the liquid outlet pipe 70 is connected to the inlet of the solenoid four-way valve.

[0040] In this solution, preferably, the surface of the main body 10 of the medicine machine is provided with a water inlet 90. The water inlet 90 is connected to the pot lid 41 through a water inlet pipe 91. A water inlet valve or a water inlet pump is provided on the water inlet pipe 91, so that when the user uses it, he only needs to put the medicinal materials into the decoction pot 40, and then the water will be automatically added.

[0041] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
