[0024] Example

[0025] like Figure 1-4 The figure shows the basic structure of a preferred embodiment of the present invention. This embodiment provides a Chinese medicine decoction device, comprising a decoction pot, a drive motor 2, and a stirring mechanism. The stirring mechanism comprises a stirring shaft 31, a set of horizontal and vertical stirring rods 32, and an inclined rod 33. The drive motor 2 is located outside the decoction pot and connected to the top of the stirring shaft 31. The stirring shaft 31 is inserted into the decoction pot, and the stirring shaft 31 is aligned with the axis of the decoction pot. The set of horizontal and vertical stirring rods 32 and the inclined rod 33 are both located inside the decoction pot. At least one set of horizontal and vertical stirring rods 32 is provided, and the set of horizontal and vertical stirring rods 32 includes a horizontal rod 321 and a vertical rod 322. At least two horizontal rods 321 are provided, all arranged longitudinally, and each horizontal rod 321 is fixedly connected to the stirring shaft 31. At least one vertical rod 322 is provided, and each vertical rod 322 is fixedly connected to all the horizontal rods 321 in its set of horizontal and vertical stirring rods 32. The inclined rod 33 is fixed on the stirring shaft 31. The two ends of the inclined rod 33 are respectively located on both sides of the stirring shaft 31, and the two ends of the inclined rod 33 are respectively at different heights. At least one inclined rod 33 is provided.

[0026] This embodiment primarily utilizes the stirring mechanism's horizontal rods 321 and diagonal rods 33 to provide centrifugal force to the medicinal materials and liquid medicine in the decoction pot. The diagonal rods 33 also provide an upward force on the medicinal materials and liquid medicine, reducing the likelihood of the medicinal materials settling at the bottom of the decoction pot and increasing the rate at which the effective ingredients in the medicinal materials are separated. Furthermore, this embodiment also incorporates longitudinal rods 322 on the stirring mechanism's horizontal rods 321. By connecting multiple horizontal rods 321, the longitudinal rods 322 enhance the stirring mechanism's structural stability and reduce the likelihood of damage to the horizontal rods 321 due to impact. Furthermore, the longitudinal rods 322 can also stir medicinal materials at different heights, enhancing the stirring mechanism's effectiveness.

[0027] Specifically, all the horizontal and vertical stirring rod groups 32 are evenly distributed around the central axis.

[0028] Specifically, an even number of horizontal and vertical stirring rod groups 32 are provided, and the horizontal rods 321 in two horizontal and vertical stirring rod groups 32 symmetrically distributed about the central axis correspond to each other. The two corresponding horizontal rods 321 are integrally formed to further improve the structural strength of the stirring mechanism. In this embodiment, two horizontal and vertical stirring rod groups 32 are provided.

[0029] In this embodiment, one diagonal rod 33 is provided, two transverse rods 321 are provided in the transverse and longitudinal stirring rod group 32, and one longitudinal rod 322 is provided. One transverse rod 321 is located below the diagonal rod 33, and the other transverse rod 321 is located above the diagonal rod 33. The longitudinal rod 322 is located on the side of the diagonal rod 33 away from the stirring shaft 31.

[0030] Specifically, the longitudinal rod 322 farthest from the stirring shaft 31 in the transverse and longitudinal stirring rod group 32 is in contact with the inner wall of the decoction pot, so as to scrape off the medicinal material residue and liquid medicine residue attached to the inner wall of the decoction pot, thereby reducing the waste of medicinal materials and the pollution of the liquid medicine.

[0031] Specifically, the longitudinal rod 322 farthest from the stirring shaft 31 in the transverse and longitudinal stirring rod group 32 includes a hard portion 3221 and a soft portion 3222. The hard portion 3221 and the soft portion 3222 are connected. The hard portion 3221 is fixedly connected to the transverse rod 321, and the soft portion 3222 contacts the inner wall of the decoction pot. While scraping off the medicinal material residue and medicinal liquid residue attached to the inner wall of the decoction pot, the wear of the decoction pot by the longitudinal rod 322 is reduced.

[0032] Specifically, in the horizontal and vertical stirring rod group 32, the horizontal rod 321 at the bottom is in contact with the bottom surface of the decoction pot to fully stir the medicinal materials deposited at the bottom of the decoction pot and increase the speed of separating out the effective components in the medicinal materials.

[0033] Specifically, the crossbar 321 includes a first rod body 3211 and a plurality of first protrusions 3212. The first rod body 3211 is fixedly connected to the stirring shaft 31, and all first protrusions 3212 are fixed to the first rod body 3211. All first protrusions 3212 are divided into at least one group, with each group comprising at least two first protrusions 3212. All first protrusions 3212 in the same group are distributed along the length of the first rod body 3211. When the first protrusions 3212 are divided into multiple groups, the first protrusions 3212 are distributed around the first rod body 3211 in groups. The diagonal rod 33 includes a second rod body 331 and a plurality of second protrusions 332. The second rod body 331 is fixedly connected to the stirring shaft 31, and all second protrusions 332 are fixed to the second rod body 331. All second protrusions 332 are divided into at least one group, with each group comprising at least two second protrusions 332. All second protrusions 332 in the same group are distributed along the length of the second rod body 331. When the second protrusions 332 are divided into multiple groups, the second protrusions 332 are distributed in groups around the second rod 331. The arrangement of the first protrusions 3212 and the second protrusions 332 increases the contact area between the stirring mechanism and the medicinal materials and the medicinal solution, thereby improving the stirring effect.

[0034] Specifically, all first protrusions 3212 in the same group are evenly distributed along the length of the first rod 3211. When the first protrusions 3212 are divided into multiple groups, the first protrusions 3212 are evenly distributed around the first rod 3211 in groups. All second protrusions 332 in the same group are evenly distributed along the length of the second rod 331. When the second protrusions 332 are divided into multiple groups, the second protrusions 332 are evenly distributed around the second rod 331 in groups.

[0035] Specifically, each first rod 3211 is provided with multiple sets of first protrusions 3212, with adjacent sets of first protrusions 3212 arranged in a staggered pattern. Each second rod 331 is provided with multiple sets of second protrusions 332, with adjacent sets of second protrusions 332 arranged in a staggered pattern. In this embodiment, each crossbar 321 is provided with two sets of first protrusions 3212, and each diagonal rod 33 is provided with two sets of second protrusions 332.

[0036] Specifically, the bottom end of the stirring shaft 31 is rotatably connected to the decoction pot, thereby improving the structural stability and reliability of the bottom portion of the stirring mechanism.

Multiple locking mechanisms 4 are arranged around the tank body 11. The locking mechanism 4 includes a locking seat 42 and a locking member 43. One end of the locking seat 42 is rotatably connected to the tank body 11, and the rotation axis of the locking seat 42 is horizontal. The other end of the locking seat 42 is threadedly engaged with the locking member 43. The locking member 43 moves on the locking seat 42 toward or away from the rotation axis of the locking seat 42 through threaded engagement with the locking seat 42. The locking member 43 can rotate with the locking seat 42 to the top of the lid body 12, locking the lid body 12 to the tank body 11.

[0038] Specifically, all locking mechanisms 4 are evenly distributed around the tank body 11. In this embodiment, four locking mechanisms 4 are provided.

[0039] Specifically, the cover 12 is provided with a first locking hole 121, and the tank body 11 is provided with a second locking hole 113. Each locking member 43 corresponds to a first locking hole 121 and a second locking hole 113. The first locking hole 121 and the second locking hole 113 are used to accommodate their corresponding locking members 43. When the locking members 43 rotate to the top of the cover 12 along with the locking seat 42, each locking member 43 rotates downward and is inserted into its corresponding first locking hole 121 and second locking hole 113, thereby locking the cover 12 on the tank body 11. It should be noted that Figure 4 In order to show the first locking hole 121, the cover 12 is disassembled. Figure 4 The cover 12 shown in FIG. Figure 1 A portion of the cover 12 is shown in FIG.

[0040] Specifically, the locking mechanism 4 further includes a support base 41 and a pin 44. The support base 41 is fixedly connected to the tank body 11. The pin 44 passes through the support base 41 and the locking base 42, rotatably connecting the support base 41 and the locking base 42. A third locking hole 411 is provided in the support base 41. When the locking members 43 rotate with the locking base 42 to above the lid body 12, each locking member 43 rotates downward and inserts into the third locking hole 411 of the locking mechanism 4 in which it is located.

[0041] Specifically, the locking member 43 includes a threaded portion 431 and a limiting portion 432. The threaded portion 431 and the limiting portion 432 are connected. The threaded portion 431 passes through the locking base 42 and is threadedly connected to the locking base 42. The threaded portion 431 can be inserted into the first locking hole 121, the second locking hole 113, and the third locking hole 411. The limiting portion 432 is located on a side of the locking base 42 away from its rotation axis.

[0042] Specifically, the decoction pot also includes a filter. A retractable inlet 112 is provided at the top of the pot body 11, allowing for the addition of medicinal materials and water without opening the lid 12. A retractable liquid outlet 111 is provided at the bottom of the pot body 11 to discharge the decoction liquid. The filter is mounted at the liquid outlet 111 to filter the medicinal residue from the liquid. A retractable residue outlet is also provided at the bottom of the pot body 11 to discharge the medicinal residue from the decoction pot. The filter is not shown in the figure.

[0043] Specifically, this embodiment further includes a valve, which is installed at the liquid outlet 111 and is used to open and close the liquid outlet 111 and regulate the flow rate of the liquid outlet 111. The valve is not shown in the figure.

[0044] In summary, this embodiment utilizes the horizontal rods 321 and diagonal rods 33 of the stirring mechanism to provide centrifugal force to the medicinal materials and liquid medicine in the decoction pot. The diagonal rods 33 also provide an upward force on the medicinal materials and liquid medicine, reducing the likelihood of the medicinal materials settling at the bottom of the decoction pot and increasing the rate at which the effective ingredients in the medicinal materials are separated. The horizontal rods 321 of the stirring mechanism are also provided with vertical rods 322. By connecting multiple horizontal rods 321, the vertical rods 322 improve the structural stability of the stirring mechanism and reduce the likelihood of the horizontal rods 321 being damaged by impact. Furthermore, the vertical rods 322 can also stir medicinal materials at different heights, thereby enhancing the stirring effect of the stirring mechanism. Furthermore, the vertical rod 322, which is farthest from the stirring shaft 31 in the horizontal and vertical stirring rod group 32, is attached to the inner wall of the decoction pot to facilitate scraping off medicinal material residue and liquid medicine residue adhering to the inner wall of the decoction pot, reducing medicinal material waste and contamination of the liquid medicine.
