[0021] For example, Figure 1 Schematic diagrams of the extraction apparatus 100 provided in some embodiments of this application are shown, such as... Figure 1 As shown, the extraction device 100 includes an extraction system 110, which specifically includes a liquid supply pump 11, a heating unit 12, and an extractor 13. The liquid supply pump 11, the heating unit 12, and the extractor 13 are connected in sequence to form a first flow path. The liquid supply pump 11 is used to drive the extraction solvent into the first flow path.

[0022] The extraction apparatus 100 also includes an air pump 14 and a controller 10. The controller 10 is communicatively connected to the air pump 14, the liquid supply pump 11, and the heating unit 12, and is used to control the air pump 14, the liquid supply pump 11, and the heating unit 12. The air pump 14, the heating unit 12, and the extractor 13 are connected in sequence to form a second flow path. The air pump 14 is used to drive the airflow into the second flow path. The controller 10 can control the air pump 14, the liquid supply pump 11, and the heating unit 12 to start or stop.

[0023] Specifically, the heating unit 12 includes a heating channel 121. The heating unit 12 can heat the extraction solvent and gas flow passing through the heating channel 121.

[0024] For example, Figure 2Schematic diagrams of the extractor 13 provided in some embodiments of this application are shown. For example... Figure 2 As shown, the extractor 13 includes an extraction chamber 131. Specifically, the liquid supply pump 11, the heating channel 121, and the extraction chamber 131 are connected in sequence through pipelines to form a first flow path; and the air pump 14, the heating channel 121, and the extraction chamber 131 are connected in sequence through pipelines to form a second flow path.

[0025] Specifically, the extraction chamber 131 is used to contain the raw material to be extracted and the extraction solvent input from the heating channel 121. The extraction solvent is used to extract the raw material to be extracted to obtain an extract. The extract is a liquid mixture containing the target soluble substance obtained after the extraction solvent extracts the target soluble substance from the raw material through the physical or chemical process of "extraction".

[0026] In the embodiments of this application, the raw material to be extracted can be any suitable raw material such as coffee powder, tea leaves, and / or traditional Chinese medicine. The extraction solvent can be any suitable liquid solvent such as water and / or alcohol. For example, when the extraction solvent is water, water can be used to extract coffee powder in the extraction chamber 131 (e.g., drip extraction or pressure extraction) to obtain coffee liquid; water can also be used to extract traditional Chinese medicine in the extraction chamber 131 to extract the effective components of traditional Chinese medicine to obtain traditional Chinese medicine liquid.

[0027] In some embodiments, the extraction device 100 can be classified into different types of extraction devices depending on the raw material to be extracted. For example, when the raw material to be extracted is coffee powder, the extraction device 100 is a coffee extraction device, i.e., a coffee machine; when the raw material to be extracted is traditional Chinese medicine, the extraction device 100 is a traditional Chinese medicine extraction device. The extraction device 100 can also be any other suitable type of extraction device.

[0028] Please continue reading. Figure 2 In some embodiments, the extractor 13 may further include a waste pipe 132 and an extractant pipe 133, wherein the waste pipe 132 and the extractant pipe 133 are respectively connected to the extraction chamber 131. The extractant in the extraction chamber 131 is discharged through the extractant pipe 133, so that the user can collect the extractant through the extractant pipe 133. The waste in the extraction chamber 131 is discharged through the waste pipe 132.

[0029] Please continue reading. Figure 2In some embodiments of this application, the extractor 13 further includes a waste valve 134 disposed on the waste pipeline 132. The waste valve 134 is communicatively connected to the controller 10, which controls the opening and closing of the waste valve 134. The waste valve 134 controls the on / off state of the waste pipeline 132. In other embodiments, the extractor 13 further includes an extractant valve 135 disposed on the extractant pipeline 133. The extractant valve 135 controls the connection between the extraction chamber 131 and the external environment. The extractant valve 135 is connected to the controller 10, which controls the opening and closing of the extractant valve 135.

[0030] Please continue reading. Figure 2 In some embodiments, the extractor 13 further includes a powder tube 136 connected to the extraction chamber 131, which is used to transport the raw material to be extracted to the extraction chamber 131. For example, when the extraction device 100 is a coffee machine, the powder tube 136 can be connected to the grinding chamber (not shown); in this case, the powder tube 136 is used to transport coffee powder from the grinding chamber to the extraction chamber 131.

[0031] Specifically, in the embodiments of this application, the operating mode of the extraction device 100 includes an extraction mode. In the extraction mode, the liquid supply pump 11 drives the extraction solvent into the first flow path, so that the extraction solvent flows into the extraction chamber 131 to extract the raw material to be extracted in the extraction chamber 131, thereby obtaining an extract. Specifically, when the heating unit 12 is turned on, the liquid supply pump 11 can drive the extraction solvent into the first flow path, so that the heated extraction solvent flows into the extraction chamber 131 to extract the raw material to be extracted in the extraction chamber 131. The extract obtained in the extraction chamber 131 can be discharged through the extract pipe 133.

[0032] After the extractant in the extraction chamber 131 is discharged through the extractant pipe, residues of the raw material to be extracted and extractant residues remain in the extraction chamber 131. Therefore, in order to clean the extraction chamber 131, the operating mode of the extraction equipment 100 also includes a self-cleaning mode. In the self-cleaning mode, the liquid supply pump 11 is used to drive the extraction solvent into the first flow path so that the extraction solvent cleans the extraction chamber 131, and the air pump 14 is used to drive the airflow into the second flow path so that the airflow dries the extraction chamber 131. Specifically, the liquid supply pump 11 can drive the extraction solvent into the first flow path when the heating unit 12 is turned on so that the heated extraction solvent cleans the extraction chamber 131; the air pump 14 can also drive the airflow into the second flow path when the heating unit 12 is turned on so that the heated airflow dries the extraction chamber 131 with hot air.

[0033] In other embodiments, when the heating unit 12 is stopped, the liquid supply pump 11 drives the extraction solvent to flow into the first flow path so that the extraction chamber 131 is pre-cleaned by the extraction solvent at room temperature; then, the heating unit 12 is turned on; subsequently, when the heating unit 12 is turned on, the liquid supply pump 11 drives the extraction solvent to flow into the first flow path so that the heated extraction solvent cleans and disinfects the extraction chamber 131.

[0034] Please see Figure 3 In some embodiments, the extraction device 100 further includes a waste treatment unit 15, which is connected to the extraction chamber 1131 via a waste pipe 132. The waste treatment unit 15 is used to receive waste discharged from the extraction chamber 131. Specifically, the waste discharged from the extraction chamber 131 may include the washing liquid formed during the cleaning process of the extraction solvent on the extraction chamber 131 in the self-cleaning mode.

[0035] Specifically, please refer to Figure 3 In some embodiments, the waste treatment unit 15 is connected to the heating unit 12 via a heat-conducting material 16; or, in other embodiments, the waste treatment unit 15 may directly contact the heating unit 12. The waste in the waste chamber exchanges heat with the heating unit 12 through the waste treatment unit 15 to absorb the heat generated by the heating unit 12, accelerating the evaporation of the extraction solvent in the waste. The heat-conducting material can specifically be a heat-conducting metal or heat-conducting adhesive, etc. In this embodiment, the heat generated by the heating unit 12 when it is turned on can be transferred to the waste chamber to heat the waste in the waste chamber, which is beneficial for promoting the evaporation of the extraction solvent in the waste.

[0036] For example, Figure 4 A structural schematic diagram of the waste treatment unit 15 is shown. (For example...) Figure 4 As shown, the waste treatment unit includes a waste chamber 41, which is connected to an extraction chamber 131 via a waste pipe 132. The waste in the extraction chamber 131 is discharged to the waste chamber 41 via the waste pipe 132.

[0037] In self-cleaning mode, the liquid supply pump 11 drives the extraction solvent to flow into the waste chamber 41 along the first flow path, so that the extraction solvent cleans the extraction chamber 131 and the waste pipe 132. The air pump 14 drives the airflow to flow into the extraction chamber 131 along the second flow path, so that the airflow dries the extraction chamber 131. Specifically, when the heating unit 12 is turned on, the liquid supply pump 11 can drive the extraction solvent to flow into the waste chamber 41 along the first flow path and the waste pipe 132, so that the heated extraction solvent cleans the extraction chamber 131 and the waste pipe 132. The air pump 14 can also drive the airflow to flow into the second flow path when the heating unit 12 is turned on, so that the heated airflow dries the extraction chamber 131 with hot air. Specifically, when the heating section 12 is turned on and the waste valve 134 and the extractor valve 135 are opened, the air pump 14 can drive the airflow into the second flow path. Thus, the heated airflow can not only be discharged to the external environment through the extractor pipe 133 to dry the extraction chamber 131 and the extractor pipe 133, but also enter the waste chamber 41 through the waste pipe 132 to promote the evaporation of the extraction solvent.

[0038] Specifically, such as Figure 4 and Figure 5 As shown, in some embodiments, the waste treatment unit 15 further includes a solid-liquid separator 42; the solid-liquid separator 42 is disposed in the waste chamber 41, and the solid-liquid separator 42 divides the waste chamber 41 into a waste residue chamber 411 and a waste liquid chamber 412, wherein the waste residue chamber 411 is connected to the extraction chamber 131 through a waste pipeline 132; the waste residue chamber 411 is also connected to the heating channel 121 through a pipeline. When the washing liquid formed during the washing process enters the waste residue chamber 411, solid-liquid separation is performed under the action of the solid-liquid separator 42 to separate the waste residue and waste liquid in the washing liquid, and the waste residue remains in the waste residue chamber 411, while the waste liquid flows into the waste liquid chamber 412 through the solid-liquid separator 42.

[0039] Specifically, in some embodiments, the solid-liquid separator 42 may be a filter screen. When the extraction device 100 is placed horizontally on the ground, the waste residue chamber 411 may be far from the ground relative to the waste liquid chamber 412, so that when the waste enters the waste residue chamber 411, the waste residue and waste liquid are separated under the action of the filter screen.

[0040] Specifically, in some embodiments of this application, the waste chamber 41 is also connected to the heating channel 121 via a pipeline, so that the air pump 14 can input airflow into the waste chamber 41 through the heating channel 121 to dry the waste in the waste chamber 41. Specifically, when the heating unit 12 is turned on, the air pump 14 can input airflow into the waste chamber 41 through the heating channel 121 to dry the waste in the waste chamber 41 with hot air after heating.

[0041] In some embodiments, the operating mode of the extraction device 100 also includes a waste treatment mode. In the waste treatment mode, when the heating unit 12 is turned on, the air pump 14 inputs airflow into the waste residue chamber 411 through the heating channel 121 to dry the waste residue using the heated airflow.

[0042] In some embodiments, the waste treatment unit 15 further includes a waste liquid pipeline 43 and a waste liquid valve 44. The waste liquid pipeline 43 is connected to the waste liquid chamber 412 and is used to discharge waste liquid from the waste liquid chamber 412. The waste liquid valve 44 is disposed on the waste liquid pipeline 43 and is used to control the opening and closing of the waste liquid pipeline 43. The waste liquid valve 44 is communicatively connected to the controller 10, and the controller 10 is used to control the opening and closing of the waste liquid valve 44. When the waste liquid valve 44 is open, the waste liquid in the waste liquid chamber 412 can be discharged through the waste liquid pipeline 43.

[0043] Specifically, in some embodiments, the waste treatment unit 15 further includes a waste residue compression unit 45 that is communicatively connected to the controller 10. The waste residue compression unit 45 is used to compress the waste residue in the waste residue chamber 411 to obtain a residue cake.

[0044] Specifically, the waste residue compression unit 45 includes: a motor 451, a drive shaft 452, and a pressure plate 453; wherein, one end of the drive shaft 452 is connected to the motor 451, and the other end of the drive shaft 452 is connected to the pressure plate 453, and the pressure plate 453 is disposed in the waste residue chamber 411; the controller 10 is communicatively connected to the motor 451, and the controller 10 is used to control the rotation of the motor 451. The motor 451 drives the pressure plate 453 to move back and forth along the compression direction of the waste residue through the drive shaft 452. For example, as... Figure 5 (a) and Figure 5 As shown in (b), the motor 451 can drive the pressure plate 453 to move in the compression direction indicated by the arrow through the transmission shaft 152, so that the pressure plate 453 compresses the waste residue 51 in the waste residue chamber 411 to obtain the residue cake 52.

[0045] In some embodiments, the waste treatment unit 15 further includes a waste liquid monitoring unit 46 communicatively connected to the controller 10. The waste liquid monitoring unit 46 is used to monitor the weight, volume, and / or height of the waste liquid in the waste liquid chamber 412. The waste liquid monitoring unit 46 may specifically include a level gauge and / or an electronic scale, etc.

[0046] In some embodiments, the waste chamber 41 is also connected to an air pump 14 via a pipeline; the air pump 14 is used to extract gas from the waste chamber 41 when the waste valve 134 and the waste liquid valve 44 are closed, so that the waste chamber 41 is in a negative pressure state and the extraction chamber 131 is in a positive pressure state. Thus, when the waste valve 134 is opened, the waste material (such as washing liquid) remaining in the extraction chamber 131 can be sucked into the waste chamber 41.

[0047] In some embodiments, in order to better maintain the negative pressure state in the waste chamber 41, a one-way valve 25 is also provided on the pipeline connecting the air outlet and the air pump 14. The one-way valve 25 allows airflow from the waste chamber 41 to the air pump 14, prevents liquid extraction solvent from flowing from the waste chamber 41 to the air pump 14, and also prevents airflow from flowing from the air pump 14 to the waste chamber 41.

[0048] In some embodiments, the waste treatment unit 15 further includes a barometer 47 communicatively connected to the controller 10, the barometer 47 being disposed in the waste residue chamber 411. The controller 10 monitors the air pressure in the waste residue chamber 411 and the waste liquid chamber 412 through the barometer 47.

[0049] Please see Figure 6 In some embodiments, the waste treatment unit 60 further includes a cake outlet 62 and a door 61 disposed at the cake outlet 62. The cake outlet 62 communicates with the waste slag chamber 411, and the cake outlet 62 is located away from the drive shaft 452 relative to the pressure plate 453. The door 61 is used to open and close the cake outlet 62. When the cake outlet 62 is opened, the motor can drive the pressure plate 453 to push the cake out of the cake outlet 62.

[0050] Please see Figure 7 In some embodiments, the waste treatment unit 70 specifically includes a main body 71, which has a waste chamber 72 and a slag cake outlet 73, and a silo door 74 is connected to the main body 71 via a connector 75. For example... Figure 7 As shown, the connector 75 can specifically be a tension spring, and the controller 10 controls the opening and closing of the compartment door 74 by controlling the extension and retraction of the tension spring. Please refer to [link / reference]. Figure 8 The connector 75 can also be a pneumatic lever. The controller 10 controls the opening and closing of the hatch 74 by controlling the pneumatic lever to push and pull the hatch door 74.

[0051] Please see Figure 1 In some embodiments, the extraction device 100 further includes an alarm 101 connected to the controller 10. The alarm 101 is used to issue an alarm message to instruct the user to open the chamber door 61. The alarm 101 may specifically include indicator lights, speakers, and / or displays. The alarm message may specifically be a flashing light emitted by an indicator light, an audio message played by a speaker, or a text message displayed on a screen.

[0052] like Figure 7 and Figure 8 As shown, the waste treatment unit 70 also includes a slag cake collection bin 76, which is connected to the waste slag chamber 72 via a slag cake outlet 73. The motor 77 can drive the pressure plate 79 through the transmission shaft 78 to push the slag cake in the waste slag chamber 72 into the slag cake collection bin 76.

[0053] Specifically, in some embodiments, the waste residue chamber 411 is closer to the heating section 12 than the waste liquid chamber 412, so that the heat generated by the heating section 12 is first transferred to the waste residue chamber 411, and then to the waste residue chamber 411. The heat in the waste residue chamber 411 is initially higher than that in the waste liquid chamber 412; then, the heat in the waste residue chamber 411 and the waste liquid chamber 412 tends to be balanced; that is, the waste residue chamber 411 will be heated first relative to the waste liquid chamber 412, and the heat absorbed by the waste residue chamber 411 will be higher than that in the waste liquid chamber 412; thus, compared with the waste liquid remaining at the bottom of the waste liquid chamber 412, the waste residue located in the waste residue chamber 411 will absorb more heat, which is beneficial to the drying of the waste residue.

[0054] In other embodiments, the waste liquid chamber 412 is closer to the heating unit 12 than the waste residue chamber 411, so that the heat generated by the heating unit 12 is first transferred to the waste liquid chamber 412 and then to the waste residue chamber 411. The heat in the waste liquid chamber 412 is initially higher than that in the waste residue chamber 411; then, the heat in the waste residue chamber 411 and the waste liquid chamber 412 tends to be balanced; that is, the waste liquid chamber 412 will be heated first relative to the waste residue chamber 411, and the heat absorbed by the waste liquid chamber 412 will be higher than that in the waste residue chamber 411; thus, compared with the waste residue in the waste residue chamber 411, the waste liquid located at the bottom of the waste liquid chamber 412 will absorb more heat, which is beneficial to the evaporation of the waste liquid.

[0055] Specifically, when the extraction equipment 100 is placed horizontally on the ground, the waste residue chamber 411 is located at the top of the waste treatment section 15, and the waste liquid chamber 412 is located at the bottom of the waste treatment section 15. For example... Figure 3 As shown, the heating unit 12 can be installed on top of the waste treatment unit 15, so that during the heat exchange between the heating unit 12 and the waste treatment unit 15, the heat from the heating unit 12 is first transferred to the waste residue chamber 411 to promote the drying of the waste residue; as Figure 9 As shown, the heating unit 12 can also be provided at the bottom of the waste treatment unit 15, so that during the heat exchange process between the heating unit 12 and the waste treatment unit 15, the heat from the heating unit 12 is first transferred to the waste liquid chamber 412 to promote the drying of the waste liquid.

[0064] In some embodiments, the first control valve 21, the second control valve 22, the third control valve 23, and the fourth control valve 24 may be solenoid valves; wherein, the third control valve 23 and the fourth control valve 24 may specifically be three-way valves.

[0065] The following explanation uses the extraction device 100 as an example of a coffee machine to illustrate the working process of the extraction device 100.

[0066] In extraction mode, when the liquid supply pump 11 and the heating unit 12 are turned on, and the waste valve 134 and the extractant valve 135 are closed, the liquid supply pump 11 drives the extraction solvent to flow into the first flow path, so that the heated extraction solvent flows into the extraction chamber 131 to extract the raw material to be extracted in the extraction chamber 131, producing an extractant. Subsequently, the extractant valve 135 opens, and the extractant in the extraction chamber 131 is discharged through the extractant pipeline 133. After the extractant in the extraction chamber 131 is discharged through the extractant pipeline, residues of the raw material to be extracted and extractant residues will remain in the extraction chamber 131.

[0067] In self-cleaning mode, firstly, when the first control valve 21 is open and the heating unit 12 is stopped, the waste valve 134 is open and the extraction liquid valve 135 is closed. Then, the supply pump 11 drives the extraction solvent to flow into the waste residue chamber 411 along the first flow path and the waste pipe, so that the unheated extraction solvent pre-cleans the extraction chamber 131 and the waste pipe 132, and the cleaned liquid is discharged into the waste residue chamber 41. Secondly, the heating unit 12 is started. At this time, when the first control valve 21 is open and the heating unit 12 is started, the waste valve 134 is open and the extraction liquid valve 135 is closed. Then, the supply pump 11 drives the extraction solvent to flow into the waste residue chamber 411 along the first flow path and the waste pipe, so that the heated extraction solvent pre-cleans the extraction chamber 131 and the waste residue chamber 411. Pipeline 132 undergoes further cleaning and disinfection, and the cleaning liquid is discharged into the waste chamber 41. Then, when the liquid supply pump 11 is turned off, the fourth control valve 24 connects the air pump 14 to the first gas supply pipeline 34, the heating unit 12 is turned on, the second control valve 22 is opened, the third control valve 23 connects the heating channel 121 to the second gas supply pipeline 35, the extractor valve 135 is opened, and the waste valve 134 is opened, the air pump 14 drives the airflow into the second flow path. Thus, the heated airflow can not only be discharged to the external environment through the extractor pipeline 133 to dry the extraction chamber 131 and the extractor pipeline 133, but also enter the waste residue chamber 411 through the waste pipeline 132 to promote the drying of the waste residue.

[0068] In self-cleaning mode, the washing liquid is discharged into the waste chamber 41, where the solid-liquid separator 42 separates the waste residue and waste liquid. The waste residue remains in the waste residue chamber 411, and the waste liquid remains in the waste liquid chamber 412.

[0069] In the waste treatment mode, firstly, the waste liquid discharge valve is opened to empty the waste liquid in the waste liquid chamber 412; then, the fourth control valve 24 connects the air pump 14 and the fourth gas supply line 37. When the waste liquid valve 44 and the waste material valve 134 are closed, the air pump 14 draws gas from the waste material chamber 41 to make the waste material chamber 41 a negative pressure state and the extraction chamber 131 a positive pressure state. Then, the fourth control valve 24 disconnects the connection between the air pump 14 and the fourth gas supply line 37 and opens the waste material valve 134 so that the waste in the extraction chamber 131 is sucked into the waste residue chamber 411; then, the waste residue compression unit 45 squeezes the waste residue in the waste residue chamber 411 to squeeze out the residual waste liquid in the waste residue; then, when the heating unit 12 is turned on, airflow is input into the waste residue chamber 411 through the heating channel 121 to dry the waste residue using the heated airflow. The waste slag compression unit 45 squeezes the dried waste slag in the waste slag chamber 411 to obtain a slag cake, and pushes the slag cake into the slag cake collection bin 76.

[0070] Therefore, the extraction equipment provided in this application embodiment can not only clean the extraction chamber itself through the liquid supply pump and air pump, but also discharge the washing liquid formed during the cleaning process to the waste treatment section to separate the waste liquid and waste residue in the washing liquid, and collect the waste residue in the waste residue chamber and the waste liquid in the waste liquid chamber. The extraction equipment can also dry and compress the waste residue in the waste residue chamber to obtain a residue cake, and then push the residue cake into the residue cake collection chamber 76. Therefore, the extraction equipment provided in this application embodiment can clean the extraction chamber itself and collect the solid residue flushed out of the extraction chamber during the cleaning process, which helps to reduce the user's manual cleaning of the extraction chamber and improve the user experience. In addition, the waste residue and waste liquid in the waste chamber can also absorb the heat energy generated by the heating section, which helps to improve the heat energy utilization rate of the heating section. At the same time, the extraction equipment provided in this application embodiment has a simple structure, which helps to simplify the manufacturing process of the extraction equipment and reduce the manufacturing cost.
