An extrusion-type Chinese medicine machine equipped with a stirring structure

Abstract

This utility model discloses a compression-type Chinese medicine machine with a stirring structure, including a main body of the machine, a decoction barrel, a cooking device, an extraction pressure plate, a drive motor, a stirring body, and a stirring motor. In operation, the extraction pressure plate can only reciprocate within the first space of the decoction barrel. The second space within the decoction barrel, located outside the first space, is not touched during the operation of the extraction pressure plate. Therefore, the stirring body is placed in this area. The stirring motor drives the stirring body to move rapidly within the second area, thereby causing the medicinal liquid in the decoction barrel to flow rapidly. This allows heat to be quickly diffused throughout the entire medicinal liquid, and the effective components of the medicinal materials to be evenly distributed in the liquid, further improving the heating efficiency of the decocted medicinal materials and the extraction rate of the effective components.

Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine machinery, and in particular to an extrusion-type traditional Chinese medicine machine equipped with a stirring structure. Background Technology

[0002] Currently, traditional Chinese medicine (TCM) decoction is mainly done in earthenware pots, a method that requires manual monitoring of the heat, making it cumbersome. To address this, the inventor designed a fully automatic TCM decoction machine, as detailed in patent application number 202320328948.4, a utility model patent titled "Extrusion-Type TCM Extraction Machine." This type of product uses an extraction plate within the cooking pot to compress and crush the medicinal materials, allowing for rapid extraction of the active ingredients. However, a problem remains: during decoction, the active ingredients in the herbs diffuse from areas of high concentration to areas of low concentration. The surface of the herbs is typically a high-concentration area; if the surface concentration remains consistently too high, it will hinder the extraction of the active ingredients. The same principle applies to heating, where heat diffuses from high-heat areas to low-heat areas. Therefore, heat exchange efficiency is also a factor affecting heating effectiveness. However, the extraction plate's efficiency in driving water flow during the lifting and pressing process remains low, resulting in insufficient extraction efficiency and heating speed. Utility Model Content

[0010] As a further improvement to the above technical solution, the decoction cylinder has an open top structure, the drive motor is located at the top of the decoction cylinder, and a cavity is provided between the drive motor and the top of the decoction cylinder. The drive motor can drive the extraction plate to move into the cavity.

[0011] As a further improvement to the above technical solution, the main body of the traditional Chinese medicine machine is provided with a push plate that can move back and forth. A door is provided at the front end of the push plate. The decoction cylinder is arranged on the surface of the push plate. The main body of the traditional Chinese medicine machine is also provided with a front-opening receiving cavity. The push plate is movably disposed at the bottom of the receiving cavity. When the push plate is completely pushed into the receiving cavity, the door covers the receiving cavity.

[0012] As a further improvement to the above technical solution, the side wall of the decoction cylinder is made of a transparent plate, and the surface of the door is provided with an observation window for observation.

[0013] As a further improvement to the above technical solution, the transparent plate is made of tempered glass.

[0014] As a further improvement to the above technical solution, the diameter of the extraction plate is A, the inner diameter of the decoction cylinder is B, where B>A, the first space is a cylindrical area with the center of the decoction cylinder as the center and a diameter of A, the second space is an annular area with a width of (BA) / 2, the main body of the traditional Chinese medicine machine is provided with a rotating component located at the top of the decoction cylinder, the stirring motor is connected to the rotating component and drives the rotating component to rotate, the stirring body is a stirring rod arranged at the bottom of the rotating component and extending into the annular area, and the rotating component drives the stirring rod to move in the annular area when it rotates.

[0025] Reference Figures 1 to 2 An extrusion-type Chinese medicine machine with a stirring structure includes a main body 10, a decoction cylinder 20 disposed on the main body 10, and a cooking device for decocting medicinal materials.

[0026] The main body 10 of the traditional Chinese medicine machine is provided with an extraction pressure plate 30 located inside the decoction cylinder 20. The main body 10 of the traditional Chinese medicine machine is provided with a drive motor 40 connected to the extraction pressure plate 30 and driving the extraction pressure plate 30 to reciprocate within the decoction cylinder 20. The operating space of the extraction pressure plate 30 within the decoction cylinder 20 is a first space. The other part of the decoction cylinder 20 excluding the first space is a second space. A stirring body is provided in the second space. The main body 10 of the traditional Chinese medicine machine is provided with a stirring motor 70 connected to the stirring body and driving the stirring body to move within the second space.

[0027] In the operation of the extrusion-type Chinese medicine machine with a stirring structure disclosed in this solution, the extraction platen 30 can only reciprocate within the first space inside the decoction cylinder 20. The second space inside the decoction cylinder 20, which is outside the first space, will not be touched by the extraction platen 30 during operation. Therefore, the stirring body is arranged in this area. The stirring motor 70 drives the stirring body to move rapidly in the second area, thereby driving the liquid medicine in the decoction cylinder 20 to flow rapidly. This allows the heat to be quickly diffused into the entire liquid medicine and the effective components in the medicinal materials to be evenly distributed in the liquid medicine, thereby further improving the heating efficiency of the decoction of medicinal materials and the extraction rate of the effective components in the medicinal materials.

[0028] Further optimization involves providing an inwardly recessed impeller cavity 50 on the inner wall of the decoction cylinder 20, with the stirring body being a stirring impeller 60 disposed within the impeller cavity 50. The stirring impeller 60 does not protrude from the inner wall of the decoction cylinder 20, and the stirring motor 70 is disposed on the decoction cylinder 20.

[0029] By providing an additional inwardly recessed impeller cavity 50 on the inner wall of the decoction cylinder 20, the stirring impeller 60 is arranged through the impeller cavity 50 and the stirring impeller 60 does not protrude from the inner wall of the decoction cylinder 20, so that the extraction plate 30 will not interfere with the stroke of the stirring impeller 60 during reciprocating movement.

[0030] In this design, the impeller cavity 50 can be located on the inner bottom surface of the decoction cylinder 20. However, this arrangement requires dividing the bottom of the decoction cylinder 20 into sections to prevent the medicinal materials from falling into the impeller cavity 50. Therefore, it is preferable that the impeller cavity 50 is located on the side wall of the decoction cylinder 20. Considering that the medicinal materials generally have a certain thickness, it is preferable that the impeller cavity 50 is located in the upper two-thirds of the side wall of the decoction cylinder 20.

[0031] In this embodiment, the impeller cavity 50 can be integrally formed onto the decoction cylinder 20. However, the manufacturing process of integral forming is quite difficult. Therefore, it is preferable that the inner wall of the decoction cylinder 20 is provided with a through-hole, including a housing 51. The impeller cavity 50 is arranged on the front end face of the housing 51. A flange 52 is arranged on the outer peripheral edge of the front end of the housing 51. The housing 51 is installed in the mounting hole through the inner side of the decoction cylinder 20, and the inner wall of the flange 52 is fixedly connected to the inner wall of the decoction cylinder 20. In other embodiments, the outer shell forming the impeller cavity 50 can also be assembled by welding it to the outside of the decoction cylinder 20, or the outer shell forming the impeller cavity 50 can be fixed to the decoction cylinder 20 by bolts. The specific manufacturing method is not limited in this embodiment.

[0032] In this embodiment, the decoction cylinder 20 preferably has an open top structure. The drive motor 40 is located at the top of the decoction cylinder 20, and a cavity is provided between the drive motor 40 and the top of the decoction cylinder 20. The drive motor 40 can drive the extraction pressure plate 30 to move into the cavity. In other embodiments, the extraction pressure plate 30 can be arranged left and right inside the decoction cylinder 20, thereby squeezing the medicinal materials by moving left and right. At the same time, the opening of the decoction cylinder 20 can be arranged on the upper side of the decoction cylinder 20.

[0033] Further optimization is preferred, where the main body 10 of the traditional Chinese medicine machine is equipped with a push plate 80 that can move back and forth. A door 90 is located at the front end of the push plate 80. The decoction cylinder 20 is arranged on the surface of the push plate 80. The main body 10 of the traditional Chinese medicine machine also has a front-opening receiving cavity 11. The push plate 80 is movably positioned at the bottom of the receiving cavity 11. When the push plate 80 is fully pushed into the receiving cavity 11, the door 90 closes the receiving cavity 11. This method allows for easy pushing or pushing of the decoction cylinder 20 out of the main body 10 of the traditional Chinese medicine machine, facilitating user operation. In this structure, since the stirring impeller 60 also moves synchronously with the decoction cylinder 20, for ease of wiring, it is preferable that the connecting wire of the stirring motor 70 is routed through the push plate 80.

[0034] Further optimization is preferred, with the sidewall of the decoction cylinder 20 preferably made of a transparent plate, and the surface of the door 90 provided with an observation window 91 for observation, so as to facilitate user observation. Preferably, the transparent plate is made of tempered glass.

[0035] In other embodiments, there are many ways to arrange the stirring impeller 60 in the second space. For example, a filter plate is arranged at the bottom of the decoction cylinder 20, and the filter plate and the bottom surface of the decoction cylinder 20 form the second space. In this case, the stirring impeller 60 can be arranged between the filter plate and the decoction cylinder 20.

[0036] For example, the diameter of the extraction plate 30 is A, and the inner diameter of the decoction cylinder 20 is B, where B > A. The first space is a cylindrical region with a diameter of A centered on the center of the decoction cylinder 20, and the second space is an annular region with a width of BA / 2. A rotating assembly is provided on the main body 10 of the traditional Chinese medicine machine, located at the top of the decoction cylinder 20. The stirring motor 70 is connected to the rotating assembly and drives it to rotate. The stirring element is a stirring rod arranged at the bottom of the rotating assembly and extending into the annular region. When the rotating assembly rotates, it drives the stirring rod to move within the annular region. Preferably, the rotating assembly is an annular wheel, and the stirring motor 70 is connected to the annular wheel and drives it to rotate. There are many ways to connect the stirring motor 70 and the annular wheel. For example, in Embodiment 1, an annular gear is provided on the inner or outer side of the annular wheel, and a drive gear meshing with the annular gear is installed at the output end of the stirring motor 70, which drives the annular wheel to rotate. For example, in Embodiment 2, a rubber wheel is provided at the output end of the stirring motor 70. The rubber wheel abuts against the surface of the annular rotating wheel, and the annular rotating wheel is driven to rotate through rolling friction.

[0037] For example, the diameter of the extraction plate 30 is 30cm, while the inner diameter of the decoction cylinder 20 is 40cm. In this case, a 5cm wide annular area is formed between the inner wall of the decoction cylinder 20 and the edge of the extraction plate 30's running trajectory. This annular area is the second space. An annular rotating wheel can be installed at the top of the decoction cylinder 20. The stirring motor 70 is connected to the annular rotating wheel and drives it to rotate. The stirring element is a stirring rod located at the bottom of the annular rotating wheel and extending into the second space. The annular rotating wheel drives the stirring rod to move rapidly within the annular second space, thereby causing the medicinal liquid to flow rapidly. Further optimization is preferred; the annular rotating wheel is preferably a sun gear, and the top of the stirring rod is equipped with planetary gears meshing with the sun gear, allowing the stirring rod to rotate on its own axis while revolving within the annular second space.

[0038] To further optimize the process and facilitate the removal of the decoction cylinder 20, the rotating assembly is preferably mounted on a movable base. The main body 10 of the herbal medicine machine contains a lifting motor that drives the movable base to rise and fall, such that the bottom of the stirring rod is higher than the top of the decoction cylinder 20. In other embodiments, the decoction cylinder 20 can also be lowered, or a detachable support base can be provided at the bottom of the decoction cylinder 20 to facilitate its removal.

[0039] 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.
