Description

Technical Field

[0001] This invention belongs to the field of medical equipment technology, and in particular relates to an automatic household decoction machine. Background Technology

[0002] Traditional Chinese medicine (TCM) prescriptions often contain herbs with different properties. Besides the usual group-decocted herbs, there are also herbs that are decocted first and added later. These different categories of herbs have different requirements for soaking and decoction times: herbs decocted first and those decocted together require soaking for 30-60 minutes each, but when decocting, herbs decocted first need to be prepared for 30-60 minutes in advance, while herbs added later only need 5-10 minutes. Therefore, different categories of herbs in TCM prescriptions have both separation and overlap in terms of timing and process. Whether these requirements can be met during the decoction process is crucial for the effective extraction of medicinal components.

[0003] Currently, there are two methods for decocting traditional Chinese medicine prescriptions: one is through a pre-prepared decoction service, and the other is to prepare the decoction yourself. While pre-prepared decoction is convenient, it's difficult to guarantee the extraction efficiency of the herbs. Furthermore, pre-prepared decoctions typically contain at least one to two weeks' worth of herbs, and the medicinal components can easily change during storage, affecting the efficacy of the medicine. Preparing the decoction yourself involves a cumbersome process, and individual differences in decoction techniques and procedures can lead to inconsistent quality, impacting the effectiveness of the medicine.

[0004] Currently, some home-use automatic decoction products have appeared on the market. However, existing technologies have the following shortcomings: they cannot automatically perform functions such as sorting and soaking, decoction and drug addition, multiple decoctions, liquid extraction, and residue pressing, requiring multiple manual operations. For example, one might manually add herbs to be decocted first, decoct for a period of time, then add herbs that have been pre-soaked for later decoctions, and then manually add more herbs during the second decoction. Furthermore, they cannot concentrate the decoction; if too little water is added during decoction, the extraction of herbs will be insufficient, making it difficult to guarantee efficacy; if too much water is added, although it is beneficial for the extraction of effective components, it creates difficulties in operations such as pouring the liquid, and the large volume of the decoction leads to poor medication adherence. Therefore, the main drawback of existing technologies is that they cannot meet the differentiated needs of different categories of drugs in a traditional Chinese medicine prescription in terms of decoction sequence and duration within the same space, resulting in a low degree of automation throughout the entire decoction process.

[0029] See attached document Figure 1-7 This application provides a detailed description of an automatic household decoction machine according to its embodiments. In short, the basic technical solution of this invention is summarized as follows:

[0030] An automatic household decoction machine includes a first barrel for holding Chinese herbs to be decocted; the first barrel includes a pre-decoction compartment and a group medicine compartment, the pre-decoction compartment being located at the bottom of the first barrel for holding herbs to be decocted first, and the group medicine compartment being located above the pre-decoction compartment for holding herbs to be decocted together; a main shaft is detachably connected to the center of the bottom plate of the first barrel; a transmission component is sleeved on the outside of the main shaft, a part of the bottom end of the group medicine compartment is a shelf, and the other part of the bottom end is empty, the shelf is detachably connected to the transmission component, and the shelf can move up and down in the vertical direction along the main shaft with the transmission component.

[0031] The following is a detailed discussion of an automatic household decoction machine provided in this application.

[0032] like Figure 1 As shown, an automatic household decoction machine includes: a top cover 1, a first barrel 3, and a second barrel 2;

[0033] The first barrel 3 is used to hold the Chinese herbal medicine to be decocted. The first barrel 3 includes a pre-decocting medicine compartment and a group medicine compartment 5. The pre-decocting medicine compartment is located at the bottom of the first barrel 3 and is used to hold the Chinese herbal medicine to be decocted first. The group medicine compartment 5 is located above the pre-decocting medicine compartment 4 and is used to hold the Chinese herbal medicine to be decocted together. The second barrel is used to contain the Chinese herbal medicine liquid. The second barrel is a container for the Chinese herbal medicine liquid during the soaking, decocting and concentration processes, and is used to protect and support the first barrel 3. Preferably, the inner wall of the second barrel is made of stainless steel to prevent moisture and rust. The second barrel is sleeved on the outside of the first barrel 3. A vertical main shaft 10 is detachably connected to the center of the bottom plate of the first barrel 3. A transmission assembly is sleeved on the outside of the main shaft 10. The group medicine compartment 5 and the transmission assembly are detachably connected, and the group medicine compartment 5 can move vertically along the main shaft 10 with the transmission assembly. The opening of the second barrel faces upward, and the top cover 1 covers the opening of the second barrel. The main shaft 10 is located at the center of the bottom plate of the second barrel and is used to transmit power.

[0034] It should be noted that the Chinese medicine in the group medicine compartment 5 is the same as the Chinese medicine for group decoction, also called group-decoction Chinese medicine or simply group-decoction medicine; part of the bottom of the group medicine compartment is a shelf 13, which can be used to load the group-decoction Chinese medicine in the group medicine compartment 5; the bottom of the other part of the group medicine compartment is open, which facilitates the introduction of the group-decoction Chinese medicine into the pre-decoction medicine compartment 4, and also facilitates the introduction of the Chinese medicine from the subsequent medicine compartment into the pre-decoction medicine compartment 4. The pre-decoction medicine compartment 4 and the group medicine compartment 5 are coaxially arranged; the shelf and transmission assembly of the group medicine compartment 5 are detachably connected. The direction closer to the main shaft is inward, and the direction farther from the main shaft is outward.

[0035] It should be noted that the timing of adding different Chinese herbs to the decoction varies, and can be categorized as decocting first, decocting in batches, or adding later. The number and order of decoctions also differ, resulting in a first decoction (also called the first decoction or simply the first decoction) and a second decoction (also called the second decoction or simply the second decoction). The first decoction involves decocting the herbs to be decocted first, followed by decocting the herbs to be decocted in batches; the second decoction includes decocting the herbs to be added later. Usually, the herbs from the first and second decoctions are evenly mixed and taken in divided doses. This ensures a consistent concentration of the decoction each time, resulting in stable efficacy.

[0036] As some alternative embodiments of this application, a transmission assembly is sleeved on the outer side of the main shaft 10. The transmission assembly and the group medicine compartment are detachably connected. The group medicine compartment moves along the main shaft under the drive of the transmission assembly. The transmission assembly can move the shelf 13 of the group medicine compartment 5 up and down, so that the Chinese medicine in the group medicine compartment 5 can be soaked. This automatic household decoction machine can realize the automatic soaking of Chinese medicine that is decocted first and Chinese medicine that is decocted in groups.

[0037] The transmission assembly includes a hollow rotating shaft 24 at the top and a nut assembly 23 at the bottom. The top end of the nut assembly 23 contacts the bottom end of the hollow rotating shaft 24, and the nut assembly 23 also supports the hollow rotating shaft 24. The nut assembly can drive the hollow rotating shaft to move up and down. Correspondingly, the main shaft 10 includes a smooth rod at the top corresponding to the hollow rotating shaft 24 and a lead screw 22 at the bottom corresponding to the nut assembly 23. The shelf and the nut assembly can be integrally formed or detachably connected, and the shelf can move up and down with the nut assembly. The combination of the nut assembly and the lead screw enables the shelf to move up and down with the nut assembly, allowing the Chinese medicine to be soaked in a specific time sequence during decoction.

[0038] The group medicine storage compartment 5 includes a compartment plate 14, which facilitates the introduction of the group-decocted Chinese medicine into the pre-decocted medicine storage compartment. The compartment plate 14 is perpendicular to the transmission assembly. The compartment plate 14 is arranged radially along the transmission assembly, and the compartment plate and the hollow rotating shaft of the transmission assembly are detachably connected. The number of compartment plates 14 can be one or more. When there are multiple compartment plates, they are spaced apart circumferentially along the transmission assembly. For example, there are 2, 3, 4, 5, 6, 7, or 8 compartment plates. In a specific embodiment, the number of compartment plates 14 is 3. The shelf plate 13 and the compartment plate 14 can rotate relative to each other. When the hollow rotating shaft rotates, the compartment plate 14 also rotates with the hollow rotating shaft. During the rotation, the compartment plate pushes the group-decocted Chinese medicine downward from the gap formed at the bottom of the group medicine storage compartment into the pre-decocted medicine storage compartment 4, while the shelf plate remains stationary. The compartment plate 14 is also called a pusher plate.

[0039] In the horizontal direction, shelf 13 is an arc-shaped plate. When making shelf 13, a circular plate is cut off at a set angle along its radius, leaving shelf 13, which is used to hold the Chinese medicine for decoction. The cut-off corner is an empty space to facilitate the introduction of the Chinese medicine for decoction. Shelf 13 is provided with mesh 17 to facilitate water injection and ventilation. Shelf 13 is fan-shaped, and the central angle of the fan of shelf 13 ranges from 30° to 330°, for example: 30°, 45°, 60°. 90°, 120°, 135°, 150°, 180°, 210°, 225°, 240°, 270°, 300°, 315°, 330°; In a specific embodiment, the number of layers 13 is 1, and the central angle of the sector of layer 13 is 270°, that is, layer 13 is a circular 3 / 4 plate surface, and the remaining circular 1 / 4 plate surface is empty, which is used to introduce the Chinese medicine for group decoction into the pre-decoction medicine chamber 4.

[0040] In one specific embodiment, to limit the shelf to only move up and down without rotating, a fifth groove (also called a dovetail groove) is provided on the inner wall of the first barrel for installing the shelf and limiting its rotation. The fifth groove improves the accuracy of shelf movement and enhances shelf stability. The opening of the fifth groove faces the direction of the main shaft, and the top of the fifth groove is connected to the top of the first barrel to facilitate shelf entry. The bottom of the fifth groove is the lowest position where the shelf moves downward, that is, the bottom of the fifth groove is flush with the lowest point of the lead screw of the main shaft. The fifth groove is vertically arranged along the height direction of the first barrel to facilitate the shelf's up and down movement along the fifth groove. The number can be one or more, such as 2, 3, 4, 5, 6, 7, or 8. Correspondingly, the shelf has outwardly extending protrusions. The fifth groove matches the protrusions of the shelf, and the protrusions extend into the fifth groove to install and fix the shelf. This restricts the rotation of the shelf while the first barrel does not rotate. On one hand, the shelf and the nut pair are integrally formed or snap-fitted together. On the other hand, the shelf is installed in the fifth groove so that it can move up and down with the nut pair within the fifth groove, but the nut pair and the shelf are restricted from rotating horizontally. This allows the main shaft to rotate while the first barrel remains stationary, and the shelf moves up and down with the nut pair. The combination of the nut pair and the shelf fixes the first barrel horizontally but allows it to move vertically.

[0041] In one specific embodiment, the second barrel has a heat insulation function; the side walls and bottom plate of the first barrel 3 are provided with mesh 17 to isolate the Chinese medicine in the first barrel 3, which can ensure that the medicine and water are in full contact, prevent the medicine from sticking to the bottom during heating, and facilitate the separation of the decoction after boiling. The opening of the second barrel faces upward, and the top cover 1 covers the opening of the second barrel; in one specific embodiment, in order to facilitate the routing of high and low voltage wires, the second barrel and the top cover 1 are hinged; in another specific embodiment, the second barrel and the top cover 1 are connected by a hinge 15.

[0042] This automatic household decoction machine includes a power system for vertically moving and rotating the shelves of the multi-drug chamber. The power system includes a first power structure and a second power structure. The first power structure is installed at the center of the bottom plate of the second barrel and provides power to the main shaft, enabling the main shaft to rotate while the top cover remains stationary. The second power structure is installed at the center of the bottom plate of the top cover, and the top cover and the second barrel are coaxially arranged. The second power structure provides power to the hollow rotating shaft of the transmission component, driving the shelves of the multi-drug chamber to rotate while the main shaft, the second barrel, and the first barrel remain stationary.

[0043] The first power structure includes a first motor, a first shaft sealing assembly 9 of the first barrel body, and a third groove of the upper cover, enabling the main shaft to rotate while the upper cover remains stationary.

[0044] In one specific embodiment, a cavity is provided at the bottom of the second barrel, and a first motor is provided in the cavity to provide power to the main shaft 10. The cavity and the first barrel are coaxially arranged. The output shaft of the first motor is located at the center of the cavity of the second barrel. A first shaft sealing assembly 9 is provided at the center of the bottom plate of the first barrel. The first shaft sealing assembly 9 and the first barrel are integrally formed. The output shaft of the first motor extends upward and out of the top plate of the cavity and inserts into the lower end of the first shaft sealing assembly 9 to provide power to the first shaft sealing assembly 9. The output shaft of the first motor and the first shaft sealing assembly 9 of the first barrel are detachably connected. The first shaft sealing assembly 9 is sleeved on the outside of the output shaft of the first motor and is snapped and fixed with the first motor. The output shaft of the first shaft sealing assembly 9 extends upward and inserts into the lower end of the main shaft 10 to provide power to the main shaft 10. The lower end of the main shaft 10 and the output shaft of the first shaft sealing assembly 9 are detachably connected. The lower end of the main shaft 10 is sleeved on the outside of the output shaft of the first shaft sealing assembly 9 and is snapped and fixed with the output shaft of the first shaft sealing assembly 9. In one specific embodiment, the first motor is provided with an output shaft that protrudes upward and has a polygonal star-shaped cross-section, and the lower end of the corresponding first shaft seal assembly 9 is provided with a first groove that has a polygonal star-shaped cross-section, and the output shaft of the first motor is inserted into the first groove and secured. In another specific embodiment, the first shaft seal assembly 9 is provided with an output shaft that protrudes upward and has a polygonal star-shaped cross-section, and the lower end of the corresponding main shaft 10 is provided with a second groove that has a polygonal star-shaped cross-section, and the output shaft of the first shaft seal assembly 9 is inserted into the second groove and secured.

[0045] In one specific embodiment, the first shaft seal assembly 9 has a protective sleeve, which is food grade, to protect the first shaft seal assembly 9 from corrosion in traditional Chinese medicine and to prevent it from affecting the rotation of the main shaft.

[0046] In one specific embodiment, the output shaft of the first motor has a protective sleeve, which is food grade, to protect the output shaft of the first motor from corrosion in the Chinese medicine liquid and to prevent it from affecting the soaking and decocting of the Chinese medicine liquid.

[0047] In one specific embodiment, a third groove is provided at the center of the upper cover 1. The opening of the third groove faces downward, and the upper end of the main shaft 10 is embedded upward into the inner side (opening) of the third groove. The upper end of the main shaft 10 and the inner side of the third groove do not contact each other. The third groove is sleeved on the outer side of the upper end of the main shaft 10. The upper cover 1 is fixed and does not affect the rotation of the main shaft 10. In another specific embodiment, the upper end of the main shaft 10 is hemispherical, and the inner side of the corresponding third groove is a hemispherical cavity (the diameter of the hemispherical cavity is larger than the diameter of the hemispherical shape at the upper end of the main shaft 10). The upper end of the main shaft 10 is embedded in the third groove to achieve the limiting and fixing of the main shaft without affecting the fixing of the upper cover.

[0048] In one specific embodiment, a hollow rotating shaft of a transmission component is provided on the outer side of the third groove, and an output shaft of a second motor is provided on the outer side of the hollow rotating shaft; that is, the hollow rotating shaft is sleeved on the outer side of the third groove, and the output shaft of the second motor is sleeved on the outer side of the hollow rotating shaft.

[0049] The top cover 1 is equipped with a controller for controlling the operation of various components, facilitating user operation. The controller has a timer function and can be set for time control. The controller is also equipped with an operation display panel for displaying the operation of various components and setting the frying program. The controller is electrically connected to the first motor, thereby controlling the operation of the first motor. The output shaft of the first motor, the first shaft seal assembly 9, the main shaft 10, the second barrel, and the first barrel 3 are coaxially arranged.

[0050] The second power structure includes a second motor, a hollow rotating shaft of a transmission assembly, and a bin plate of a medicine bin that is detachably connected to the hollow rotating shaft; the second motor drives the hollow rotating shaft and the bin plate to rotate, while the main shaft, the second bin and the first bin remain unaffected and stationary.

[0051] A second motor is installed in the upper cover 1 to provide power to the hollow rotating shaft 24 of the transmission component, enabling the second motor to drive the hollow rotating shaft 24 to rotate while the main shaft 10 remains stationary. The controller is electrically connected to the second motor to control its operation. The second motor can control the rotation angle; specifically, it can be a stepper motor, such as a PM-type (permanent magnet) or HY-type (hybrid) micro stepper motor, facilitating the introduction of the Chinese medicine from the group medicine compartment 5 into the pre-decoction compartment 4 of the first barrel 3 through the gaps in the plate. Only when the nut assembly 23 rises with the lead screw 22 to the highest point of the lead screw 22 will the hollow rotating shaft 24 be embedded in the output shaft of the second motor. The output shaft of the second motor is fixed by rotation and engagement with the hollow rotating shaft 24. The second power structure enables the rotation of the compartment plate for stirring and introducing the group-decoction Chinese medicine.

[0052] As some alternative embodiments of this application, the top of the cover 1 is provided with an exhaust hole, which is connected to the second barrel body and is used to discharge the gas inside the second barrel body.

[0053] The outer wall of the top cover 1 is provided with a water inlet 18 for connecting a water source. The water source can be cooled boiled water, tap water that has been settled or filtered, and preferably purified water to reduce the interference of water quality on the medicinal liquid, ensure the stability of the decoction process and avoid impurities affecting the efficacy. The bottom plate of the top cover 1 is provided with a water inlet 19 for injecting water into the first barrel 3. The water inlet 18 and the water inlet 19 are connected. The number of water inlets 19 can be one or more, such as 2, 3, 4, 5, 6 or 7. In a specific embodiment, the number of water inlets 19 is 3. The top cover 1 is provided with a cavity, and a liquid outlet 11 is provided on the outer circumference of the top cover 1 for discharging the Chinese medicine liquid. A water pump is installed in the cavity of the top cover 1 to provide power for water injection and discharge of Chinese medicine liquid. The water pump is electrically connected to the controller, and the controller controls the operation of the water pump. In the second barrel 2, the Chinese medicine liquid is sucked into the top cover 1 by the water pump through the suction pipe 33, and then discharged through the outlet 11. The number of water pumps can be one or two. In one specific embodiment, there is one water pump; in another specific embodiment, there are two water pumps, one for powering water injection and the other for powering the discharge of the herbal decoction. A water pipe is installed inside the cavity to provide a flow path for the herbal decoction and water source. The water pipe can connect the water pump and the outlet 11 to discharge the herbal decoction. Alternatively, the water pipe can connect the water pump to the inlet 18 and the injection port 19. When water enters, the pressure from the water pump causes the injection port 19 to spray water into the first barrel 3. During the second decoction, the pressure from the water pump spraying water from the injection port 19 flushes any remaining herbal medicine on the shelf 13 of the herbal compartment 5 into the pre-decoction compartment 4 of the first barrel 3, leaving no residual herbal medicine. The water pump and water pipe can be integrally formed or detachably connected. A valve assembly can also be installed in the water pipe to control the opening and closing of the water pipe. The valve assembly is connected to the water pump and electrically connected to the controller. The controller controls the opening and closing of the valve assembly.

[0054] As some alternative embodiments of this application, a suction pipe 33 is vertically arranged between the second barrel and the first barrel 3 for discharging the traditional Chinese medicine liquid; the second barrel and the suction pipe 33 are detachably connected, specifically, the second barrel and the suction pipe 33 are snapped together; a fourth groove is provided in the bottom plate of the second barrel, corresponding to the lower end of the suction pipe 33 extending into the fourth groove, the diameter of the fourth groove is slightly larger than the diameter of the suction pipe 33, the second barrel is provided with a slope with the fourth groove as the lowest point to ensure that the traditional Chinese medicine liquid always flows to the fourth groove, the lower end of the suction pipe 33 is close to the bottom plate of the fourth groove of the second barrel, thereby realizing that almost all the traditional Chinese medicine liquid in the second barrel is discharged, specifically, the distance from the lower end of the suction pipe 33 to the bottom plate of the fourth groove does not exceed 10mm. In one specific embodiment, a filter is detachably connected to the lower end of the suction tube 33 to prevent Chinese medicine residue from entering the suction tube 33. Specifically, the lower end of the suction tube 33 is screwed to the filter, which is equipped with a filter screen for filtering Chinese medicine residue. The filter screen is removable for cleaning and replacement. The number of filter screens can be one or more, such as two, three, four, or five layers. In one specific embodiment, the number of filter screens is set to two, thereby ensuring that there is no residue in the Chinese medicine liquid. The suction tube 33 is connected to the outlet 11 and the water pump, and the water pump provides power to the suction tube 33 to draw the Chinese medicine liquid. The upper cover 1 is provided with a suction tube compartment 37 corresponding to the top end of the suction tube 33. The suction tube compartment 37 has an upward-facing inner cavity, which is fitted outside the top end of the suction tube 33. The inner cavity of the suction tube compartment 37 is detachably connected to the suction tube 33. The inner cavity of the suction tube compartment 37 is connected to the outlet 11, so that the Chinese medicine liquid of the second barrel can be discharged through the outlet 11 by the suction tube 33 powered by the water pump.

[0055] The bottom plate or inner wall of the second container is equipped with an electric heating device for heating the herbal liquid. The electric heating device can be a heating plate or a heating resistance wire. Preferably, the electric heating device is located on the inner wall of the second container to prevent scorching. The second container, the first container 3, and the top cover 1 are coaxially arranged. The outer wall of the second container is made of heat-insulating material, such as plastic, and a power interface is provided on the outer wall for connecting to a power source.

[0056] The upper cover 1 is provided with a rear medicine compartment 6 for placing the medicine to be placed later. The rear medicine compartment 6 is cylindrical with a circular cross-section and a diameter ranging from 70 to 90 mm, for example, 70, 75, 80, 85, or 90 mm, preferably 80 mm. The height of the rear medicine compartment 6 also ranges from 70 to 90 mm, for example, 70, 75, 80, 85, or 90 mm, preferably 80 mm. In a specific embodiment, the volume of the rear medicine compartment 6 is 0.4 L. The bottom plate of the rear medicine compartment 6 is a tray, which is circular. The tray is located above the empty part of the group medicine compartment 5. The area of ​​the tray is smaller than the area of ​​the empty part of the group medicine compartment 5. The tray can be flipped (i.e., opened and closed), thereby facilitating the introduction of the medicine from the rear medicine compartment 6 into the pre-decoction compartment 4 of the first barrel 3. The upper cover 1 includes a top cover 30 for sealing the upward opening of the rear medicine compartment 6.

[0057] In one specific embodiment, a rotating shaft along the diameter of the tray divides the tray into two semicircles 36. These two semicircles 36 rotate downwards by 90 degrees along the diameter, guiding the Chinese medicine in the tray into the pre-decoction chamber 4 of the first barrel 3. The rotation of the two semicircles 36 can be achieved electrically. In another specific embodiment, an electromagnetic lock is provided in the rear medicine chamber to control the rotation of the two semicircles 36. Specifically, the electromagnetic lock includes suction plates arranged on the outer edges of the two semicircles and an electromagnetic body with corresponding suction plates arranged in the inner wall of the rear medicine chamber. The controller and the electromagnetic body are electrically connected, and the controller controls the on / off state of the electromagnetic body. When the controller controls the electromagnetic body to be energized, the magnetic forces repel each other, and the two semicircles 36 rotate downwards due to gravity, guiding the Chinese medicine in the rear medicine chamber into the pre-decoction chamber 4 of the first barrel 3. Opening the top cover 30 and opening the two semicircles 36 of the tray can replace the above-mentioned venting holes for venting. After decoction is completed, the two semicircles can be manually closed.

[0058] In one specific embodiment, the rear medicine compartment is equipped with a locking mechanism. The controller and the locking mechanism are electrically connected to control the extension and retraction of the locking mechanism. The locking mechanism includes a pair of telescopic tongues, which are positioned opposite each other on the inner wall of the rear medicine compartment at the end away from the flipping axis. In the normal state, the end of one telescopic tongue extends out and blocks the bottom of a semicircle to support it. When the controller provides power, the end of the telescopic tongue retracts into the inner wall of the rear medicine compartment, and the two semicircles flip downwards due to gravity, guiding the Chinese medicine from the rear medicine compartment into the pre-decoction compartment 4 of the first barrel. The top cover is opened to serve as a venting channel. After decoction is completed, the two semicircles can be manually closed.

[0059] As some alternative embodiments of this application, the automatic household decoction machine also includes a liquid level detection device disposed on the inner side wall of the second barrel, used to measure the liquid level of the Chinese medicine liquid in the second barrel; the liquid level detection device is communicatively connected to the controller, thereby enabling the automatic household decoction machine to operate automatically at a set liquid level. When adding water, the water level is set, and the controller controls the valve assembly to automatically stop adding water based on the water level detected by the liquid level detection device; when concentrating, the concentrated liquid level is set, and the controller controls the automatic stopping of heating and concentration based on the concentrated liquid level detected by the liquid level detection device, maintaining the temperature to the set temperature. In a specific embodiment, the specific model of the liquid level detection device is Shenzhen Nengdian Technology's 1901D or D2LS.

[0060] As some alternative embodiments of this application, the automatic household decoction machine also includes a collar and a stirring assembly 12 for concentrating the Chinese herbal medicine liquid. It should be noted that concentration is usually carried out after the Chinese herbal medicines of the first and second decoctions are evenly mixed. When concentrating the Chinese herbal medicine liquid, the first tank 3 is usually not needed. The first tank 3, the main shaft and the transmission assembly are removed, and the Chinese herbal medicine liquid of the first and second decoctions is introduced into the second tank. The collar is used to provide a mounting position for the stirring assembly 12. In order to better stir and prevent scorching, the stirring assembly 12 is installed at the bottom of the second tank. The collar is sleeved on the output shaft of the first motor. The collar and the output shaft of the first motor are detachably connected. The first motor can drive the collar to rotate. In a specific embodiment, the output shaft of the first motor is inserted into the collar and locked in place, so that the first motor drives the collar and the stirring assembly 12 to rotate and stir the Chinese herbal medicine, while the second tank remains stationary. In one specific embodiment, multiple mounting tubes are arranged along the circumference of the collar for mounting the stirring assembly 12. The number of mounting tubes is 2, 3, 4, 5, 6, 7, or 8. Preferably, four mounting tubes are arranged along the circumference of the collar. The mounting tubes correspond to the stirring assemblies 12 and are the same in number. The mounting tubes and the stirring assemblies 12 are detachably connected; specifically, the mounting tubes and the stirring assemblies 12 are snap-fitted or abutted together. In another specific embodiment, the sleeve and the mounting tube are integrally formed. The sleeve and the stirring assembly 12 are detachably connected; specifically, the sleeve and the stirring assembly 12 are snap-fitted or abutted together. Of course, the collar and the stirring assembly 12 can also be integrally formed. In one specific embodiment, the stirring assembly 12 is a stirring blade; in another specific embodiment, the stirring assembly 12 is a stirring rod.

[0061] In one specific embodiment, the second barrel is used to support the first barrel and also has a heat insulation function. The outer wall of the second barrel is made of heat insulation material, such as plastic. The outer wall of the second barrel is provided with a power interface for connecting to a power source. The second barrel is sleeved on the outside of the first barrel, and the second barrel and the first barrel are detachably connected. The second barrel and the first barrel can be snapped together and fixed, and the first barrel can also be placed directly inside the second barrel. The design of the second barrel frees up the first barrel, making the first barrel detachable and convenient for cleaning and maintenance.

[0062] In one specific embodiment, except for the protrusion corresponding to the fifth groove, the outer diameter of the remaining portion of the shelf of the group medicine compartment is smaller than the inner diameter of the first barrel, so that the shelf of the group medicine compartment and the inner diameter of the first barrel do not contact each other; the shelf 13 is integrally formed with the transmission assembly or detachably connected, specifically, the shelf 13 is snap-fitted to the transmission assembly. It should be noted that if the transmission assembly is sleeved on the outer side of the main shaft 10, then the shelf 13 is integrally formed with the transmission assembly or detachably connected (e.g., snap-fitted); if there is no transmission assembly on the outer side of the main shaft 10, the shelf 13 is detachably connected to the main shaft 10 (e.g., snap-fitted).

[0063] When the nut assembly 23 moves up and down, it drives the hollow rotating shaft 24 to move up and down. After the nut assembly 23 rises to the highest point of the lead screw 22, it stops rising, connecting the hollow rotating shaft 24 to the output shaft of the second motor in the upper cover. The hollow rotating shaft 24 rotates with the second motor, and the storage plate 14 rotates with the hollow rotating shaft 24. After this, the storage plate and the hollow rotating shaft will not move up and down, but the shelf can still move up and down with the nut assembly. In this embodiment, the shelf 13 of the group medicine storage 5 is detachably connected (installed) to the nut assembly 23 along its circumference, allowing the shelf 13 to move up and down with the nut assembly 23, thus enabling the traditional Chinese medicine in the group medicine storage 5 to soak downwards. In a specific embodiment, the shelf 13 and the nut assembly 23 are snap-fitted together.

[0064] The tray plate 14 of the group medicine compartment 5 is detachably connected (installed) to the hollow rotating shaft 24 radially. The tray plate 14 can move up and down with the hollow rotating shaft 24. When the tray plate 14 rotates with the hollow rotating shaft 24, it does not affect the shelf plate 13 of the group medicine compartment 5, i.e., the shelf plate 13 remains stationary. Because the nut pair 23 supports the hollow rotating shaft 24, during soaking, when the shelf plate 13 descends with the nut pair 23, the tray plate 14 also descends with the hollow rotating shaft 24. When the shelf plate 13 rises with the nut pair 23, the tray plate 14 also rises with the hollow rotating shaft 24. When the nut pair 23 rises to the highest point of the lead screw 22, it stops rising, thus connecting the hollow rotating shaft 24 and the output shaft of the second motor. The design of the transmission component and the group medicine compartment 5 enables the automatic lifting and lowering of the shelf plate of the group medicine compartment 5 and the automatic soaking of Chinese medicine without manual operation, significantly improving the degree of automation.

[0065] In practical applications, when soaking Chinese medicine, the pre-decocted herbs in the pre-decocted herb compartment 4 and the group-decocted herbs in the group-decocted herb compartment 5 can be soaked together. At this time, the lead screw 22 of the main shaft 10 drives the nut pair 23 to rotate in the forward direction, which in turn drives the shelf 13 of the group-decocted herb compartment 5 to move downward, so that the group-decocted herbs in the group-decocted herb compartment 5 can be submerged below the water surface. The operation display panel controls the first motor to stop the shelf 13 at the set position. The hollow rotating shaft 24 and the compartment plate 14 descend with the nut pair 23. The shelf 13 moves downward with the nut pair 23 to realize the joint soaking of the group-decocted herbs and the pre-decocted herbs in the group-decocted herb compartment 5. At the end of the first and second decoctions, the descending shelf 13 can also squeeze the Chinese medicine at the bottom of the first tank 3, achieving more thorough separation of liquid and residue. When adding water during the second decoction, the remaining Chinese medicine on the shelf 13 can be flushed into the first tank 3 to avoid loss of Chinese medicine. At the same time, the Chinese medicine liquid squeezed by the shelf 13 is flushed into the second tank. After the soaking of the Chinese medicine in the decoction is completed, the lead screw 22 of the main shaft 10 drives the nut pair 23 to rotate in the opposite direction. The shelf 13 rises with the nut pair 23 to the highest point of the lead screw 22 (the highest point of the shelf 13 does not exceed the top of the lead screw 22). The hollow rotating shaft 24 and the bin plate 14 also rise with the nut pair 23 to the highest point of the lead screw 22. The output shaft of the second motor is sleeved on the outside of the hollow rotating shaft 24. The output shaft of the second motor and the hollow rotating shaft 24 are locked together by rotating the output shaft of the second motor. After that, the hollow rotating shaft 24 will no longer descend or rise with the nut pair 23. The shelf can also move up and down with the nut pair.

[0066] The herbs are boiled over high heat and then simmered over low heat for the set decoction time. Once the set time is reached, heating is stopped; this process constitutes the decoction process for the herbs to be decocted first. Then, the second motor drives the hollow rotating shaft 24 to rotate, which in turn drives the plate 14 of the group medicine chamber 5 to rotate without affecting the fixation of the shelf 13. The group medicine is then introduced into the pre-decoction chamber through the gap. Water is then added for decoction, and the herbs are boiled over high heat and then simmered over low heat for the set time; this process constitutes the decoction process for the group medicine.

[0067] It should be noted that when the nut assembly 23 is not at the highest point of the lead screw 22, the output shaft of the second motor and the hollow rotating shaft 24 are not connected. The Chinese herbs do not need to be soaked before being added to the medicine bin 6. Some Chinese herbal formulas do not require pre-decocted herbs; the above-mentioned pre-decocted herb step can be omitted. The steps for decocting Chinese herbs can be adjusted appropriately according to actual needs.

[0068] As some alternative implementations of this application, the first motor may be a motor with an electromagnetic brake, thereby stopping the shelf 13 of the pharmacy 5 at a set position height. In other words, the shelf 13 is stopped at a set position height by operating the display panel controller.

[0069] In one specific embodiment, to ensure that the hollow rotating shaft 24 does not interfere with the nut assembly 23 when rotating, buffer layers are respectively provided at the bottom end of the hollow rotating shaft 24 and the top end of the nut assembly 23 to reduce the friction between the hollow rotating shaft 24 and the nut assembly 23, so that the rotation of the hollow rotating shaft 24 does not affect the nut assembly 23. Specifically, the buffer layer can be polytetrafluoroethylene (Teflon) or a ceramic coating. In one specific embodiment, the controller controls the nut assembly 23 to descend a certain distance, creating a gap between the hollow rotating shaft 24 and the nut assembly 23, avoiding contact with the hollow rotating shaft 24 and preventing friction that could affect rotation.

[0070] In use, the first barrel 3 (including the main shaft 10 and transmission components), the shelf 13 and the compartment 14 of the group medicine compartment 5 are installed sequentially; the first-decocted Chinese medicine is put into the first-decocted medicine compartment 4 of the first barrel 3 through the empty part of the group medicine compartment 5; the group-decocted Chinese medicine is placed on the shelf 13 of the group medicine compartment 5; the suction pipe 33 is installed; the top cover 1 is closed, and the subsequent Chinese medicine is put into the subsequent medicine compartment 6 to complete the addition of Chinese medicine; the decoction start button on the operation display panel is turned on, the water pipe valve is opened, and water enters the first barrel 3 through the water inlet 18 and the water outlet 19 in sequence. When the water volume is reached, the water filling stops automatically.

[0071] In one specific embodiment, the first-soaked Chinese herbs are placed in the pre-decoction chamber 4, and the later-soaked Chinese herbs are placed in the group-decoction chamber 5. A pre-soaking time is set, and water is added for soaking. When the pre-soaking time is reached, the shelf 13 descends to the set position. At this time, the chamber plate 14, i.e., the hollow rotating shaft 24, also descends with the nut pair 23, and the later-soaked Chinese herbs are soaked according to the set later-soaking time. After the group-decoction Chinese herbs are soaked, the shelf 13 rises with the nut pair 23 to the highest point of the lead screw 22. The hollow rotating shaft 24 and the chamber plate 14 also rise with the nut pair 23 to the highest point of the lead screw 22. At this time, the output shaft of the second motor is sleeved on the outside of the hollow rotating shaft 24. The output shaft of the second motor and the hollow rotating shaft 24 are locked together by rotating the output shaft of the second motor. After this, the hollow rotating shaft 24 no longer descends or rises with the nut pair 23. Then, the decoction process of the pre-decoction and group-decoction is carried out according to the above-described process, which will not be described in detail here.

[0072] The above-mentioned decoction can be used as the first decoction. In addition to setting a specified decoction time, the liquid level can also be set to reach a certain level through a liquid level detection device. When heating is turned off, the outlet 11 of the top cover 1 is opened for the first time, and the Chinese medicine liquid in the second barrel 2 flows out or is pumped out through the outlet 11. The mesh 17 of the first barrel 3 can filter the Chinese medicine liquid, leaving the dregs in the first barrel 3. The Chinese medicine liquid is filtered into the second barrel, and the filter of the suction pipe 33 further filters the dregs, and the clean Chinese medicine liquid flowing out of the outlet 11 is connected to the first storage tank.

[0073] Once the liquid level detection device in the second tank 2 detects that the medicinal liquid has emptied, the second decoction can begin. The decoction process for the second decoction is the same as the first decoction, but a shorter decoction time is usually set. When adding water for the second decoction, any remaining medicinal herbs on the shelf 13 can be flushed into the first tank 3 to avoid loss of herbs. It should be noted that the herbs in the subsequent decoction chamber 6 do not need to be soaked. Then, the second decoction begins. Before the second decoction time is reached (which can be set 3-5 minutes before the second decoction time is reached), the two semicircles 36 of the tray of the subsequent decoction chamber 6 are flipped downwards, and the herbs in the subsequent decoction chamber 6 are introduced into the pre-decoction chamber 4 of the first tank 3 through the gap on the plate of the group medicine chamber 5. Together with the other herbs in the pre-decoction chamber 4, they are simmered over low heat until the time for the subsequent decoction is reached. After the decoction is completed, the controller stops heating. During the above decoction process, appropriate adjustments can be made according to the actual situation.

[0074] After the second decoction is completed, the liquid outlet 11 of the top cover 1 is opened for the second time, and the Chinese medicine liquid in the second barrel 2 flows out through the liquid outlet 11. The Chinese medicine liquid flowing out of the liquid outlet 11 is connected to the second storage tank. At this time, the main shaft rotates and drives the nut pair and the shelf 13 to descend, squeezing the Chinese medicine at the bottom of the first barrel 3, promoting the full separation of liquid and residue, and then flowing out through the liquid outlet 11 to the second storage tank. The Chinese medicine liquid in the second storage tank is mixed with the Chinese medicine liquid in the first storage tank. The mixed Chinese medicine liquid can be taken directly or further concentrated.

[0075] During concentration, the first container 3, along with the herb storage compartment 5, is removed. The first container 3 is not reinstalled during concentration; only the sleeve with the stirring component 12 is reattached to the second container 2. The combined herbal liquid is poured into the second container 2, and the top cover 1 is closed. Concentration is initiated, and the electric heating device begins heating. The first motor drives the stirring component 12 to rotate, accelerating dissolution and evaporation and preventing the herbal liquid from scorching at the bottom. Heating stops once the concentrated volume is reached, as measured by the liquid level detection device. The outlet 11 of the top cover 1 opens, allowing the concentrated herbal liquid to flow into the third storage tank for convenient consumption.

[0076] This application provides an automatic household decoction machine, which employs a pre-decoction chamber 4, a group decoction chamber, and a post-decoction chamber 6 to complete decoction in multiple ways, such as pre-decoction, group decoction, and post-decoction. It can achieve soaking, decoction, dregs pressing, and liquid concentration, and can easily obtain concentrated Chinese herbal decoctions. The shelf 13 has a mesh 17 to enable rapid water injection, improve decoction efficiency, and allow the medicine to be decocted and taken on the same day. It maximizes the effective extraction of the prescription, ensures the efficacy of Chinese medicine, facilitates consumption, and increases patient compliance with Chinese medicine.

For the sake of brevity, not all possible combinations of the technical features of the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
