[0031] Figure 1 This is a schematic diagram of the structure of an extraction device. Figure 1The extraction device comprises a hanging basket assembly 11 and an extraction kettle 12. The hanging basket assembly 11 can hold raw materials within a fixed volume range. The extraction kettle 12 is filled with an extraction solvent and defines a space for extraction.

[0032] Reference Figure 1 In the extraction process, the raw materials contained in the hanging basket assembly 11 need to be immersed in the extraction solvent for extraction. In order to ensure the extraction effect, it is necessary to ensure that the raw materials contained in the hanging basket assembly 11 are all extracted.

[0033] However, the existing extraction device is limited by the hanging basket assembly 11. When the volume of the extraction solvent in the extraction kettle 12 remains unchanged, the amount of the raw material contained in the hanging basket assembly 11 immersed in the extraction solvent (hereinafter referred to as the immersion amount) is fixed and cannot be adjusted. Figure 1 After the hanging basket assembly 11 is placed in the extraction kettle 12, the liquid level of the extraction solvent can only reach the L1 position, resulting in the ratio of raw materials to extraction solvent (i.e., the material-water ratio) not being able to reach the optimal level. The optimal material-water ratio is the prerequisite for obtaining the extract with the best flavor. Therefore, it is difficult to obtain the extract with the best flavor using the existing extraction device.

[0034] To address this problem, the present invention provides an extraction device, in which at least one of the volume of the hanging basket and the position of the hanging basket in the extraction kettle is adjustable. Whether changing the volume of the hanging basket or changing the position of the hanging basket in the extraction kettle, the adjustable space of the material-water ratio of the extraction device can be increased, and ultimately an extract with the best flavor can be obtained.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] The present invention provides an extraction device, which includes:

[0037] A hanging basket assembly, comprising a hanging basket for containing raw materials to be extracted;

[0038] and an extraction kettle for containing an extraction solvent;

[0039] Wherein, at least one of the volume of the hanging basket and the position of the hanging basket in the extraction kettle is adjustable.

[0040] In a specific implementation, the raw material to be extracted can be tea, herbs, coffee, preserved fruits, Chinese medicinal materials, etc., which can be used for extraction, and are not limited here. The extraction solvent can be a solvent such as cold water or hot water that can be used to extract the raw material to be extracted.

[0041] If the volume of the extraction solvent in the extraction kettle remains unchanged, the volume of the hanging basket can be reduced to increase the amount of raw material immersed in the extraction solvent, thereby increasing the material-to-water ratio. If the volume of the extraction solvent is large, the volume of the hanging basket can be increased to reduce the amount of raw material immersed in the extraction solvent, thereby reducing the material-to-water ratio. In this way, by changing the volume of the hanging basket, the adjustable range of the material-to-water ratio of the extraction device can be increased.

[0042] When the volume of the extraction solvent in the extraction kettle remains unchanged, if the volume of the extraction solvent is small, the position of the hanging basket in the extraction kettle can be lowered so that the hanging basket is more completely immersed in the extraction solvent, thereby increasing the material-water ratio. If the volume of the extraction solvent is large, the position of the hanging basket in the extraction kettle can be raised to change the amount of the raw material to be extracted immersed in the extraction solvent, thereby reducing the material-water ratio.

[0043] In some embodiments, the basket's position within the extraction kettle can be changed while the basket's volume is changed, thereby significantly increasing the adjustable range of the extraction apparatus's material-to-water ratio. For example, when the volume of the extraction solvent is small, the basket's position within the extraction kettle can be lowered while the basket's volume is reduced, thereby allowing the basket to be more completely immersed in the extraction solvent and thus increasing the material-to-water ratio. When the volume of the extraction solvent is large, the basket's position within the extraction kettle can be raised while the basket's volume is increased, thereby reducing the amount of the extracted material immersed in the extraction solvent and thus reducing the material-to-water ratio.

[0044] That is to say, by adopting the solution of the utility model, whether changing the volume of the hanging basket or changing the position of the hanging basket in the extraction kettle, the adjustable space of the material-water ratio of the extraction device can be increased, and ultimately the extract with the best flavor can be obtained.

[0045] In specific implementations, various implementation methods can be adopted to make the volume of the hanging basket adjustable.

[0046] In one embodiment of the present invention, the hanging basket can be divided into a plurality of hanging basket units, and the volume of the hanging basket can be adjusted by adjusting the number of the hanging basket units.

[0047] Specifically, Figure 2 This is a structural diagram of a hanging basket assembly in an embodiment of the present utility model. Figure 2 The hanging basket 21 includes: a hanging basket top cover 211, a hanging basket bottom plate 212, and at least one hanging basket unit 213 located between the hanging basket top cover 211 and the hanging basket bottom plate 212.

[0048] In a specific implementation, the number of hanging basket units 213 can be changed according to the volume of the extraction solvent in the extraction kettle. When there are two or more hanging basket units 213, the two or more hanging basket units 213 are distributed along the immersion direction of the extraction solvent in the extraction kettle (i.e., direction A), and the two or more hanging basket units 213 are detachably connected.

[0049] When the volume of the extraction solvent in the extraction kettle is small, the number of the hanging basket units 213 can be reduced. When the volume of the extraction solvent in the extraction kettle is large, the number of the hanging basket units 213 can be increased. Figure 2 The hanging basket 21 includes three hanging basket units 213, which are distributed along the immersion direction of the extraction solvent in the extraction kettle. In this way, when the number of basket units 213 is increased or decreased, the immersion amount of the hanging basket 21 in the extraction solvent can be changed, thereby changing the material-water ratio.

[0050] In one embodiment of the present invention, the structure of each hanging basket unit can be the same. For example, each hanging basket unit can include: a mesh, a mesh fixing member, a first connecting member 213a and a second connecting member 213b (see Figure 2 ). The mesh fixing member is connected to the upper and lower edges of the mesh and fixes the mesh; the first connecting member 213a and the second connecting member 213b are both located on the mesh fixing member and are used to connect the hanging basket unit to other components of the hanging basket.

[0051] In a specific implementation, the mesh may be a cylindrical stainless steel mesh. A plurality of holes may be evenly distributed on the mesh, and the diameter of the holes may be set according to extraction requirements, for example, the hole diameter may be set to about 1 mm.

[0052] In a specific embodiment, the mesh fixing member may include multiple stainless steel plates distributed along the edges of the cylindrical stainless steel mesh. Some of the stainless steel plates cover the upper edge of the mesh, while the remaining stainless steel plates cover the lower edge of the mesh. The mesh may be fixed to the stainless steel plates using screws, thereby reinforcing the mesh through the stainless steel plates.

[0053] In a specific implementation, the first connecting member 213a and the second connecting member 213b can be implemented in a variety of ways, as long as they can connect the hanging basket unit to other components of the hanging basket. For example, the first connecting member 213a can be a stainless steel buckle, and the second connecting member 213b can be a stainless steel hook, and the stainless steel buckle can be tightly hung on the stainless steel hook. For another example, the first connecting member 213a can be a stainless steel protrusion, and the second connecting member 213b can be a stainless steel through-hole, and the stainless steel protrusion can be inserted into the stainless steel through-hole and cannot be easily pulled out.

[0054] In a specific implementation, the first connecting member 213a and the second connecting member 213b can be evenly distributed along the circumference of the hanging basket mesh. For example, the number of the first connecting member 213a and the second connecting member 213b can be set to 4 respectively, and the positions of the first connecting member 213a and the second connecting member 213b of adjacent hanging basket units 213 correspond to each other.

[0055] In a specific implementation, the first connecting member 213a can be disposed on the stainless steel plate at the upper edge of the mesh. The second connecting member 213b can be disposed on the stainless steel plate at the lower edge of the mesh. In this case, when two or more hanging basket units 213 are distributed along the immersion direction of the extraction solvent in the extraction kettle, the first connecting member 213a can be connected to the second connecting member 213b of the adjacent previous hanging basket unit 213, and the second connecting member 213b can be connected to the first connecting member 213a of the adjacent next hanging basket unit 213. This allows for a sealed connection between adjacent hanging basket units 213.

[0056] In a specific embodiment, when the first connecting member 213a of the hanging basket unit 213 is disposed on the stainless steel plate at the upper edge of the mesh, and the second connecting member 213b of the hanging basket unit 213 is disposed on the stainless steel plate at the lower edge of the mesh, the second connecting member 213b can be correspondingly disposed on the hanging basket top cover 211, and the first connecting member 213a can be correspondingly disposed on the hanging basket bottom plate 212. In this way, the second connecting member 213b of the hanging basket top cover 211 can cooperate with the first connecting member 213a of the adjacent hanging basket unit 213, thereby providing a hermetic connection between the hanging basket top cover 211 and the adjacent hanging basket unit 213. The second connecting member 213b of the hanging basket bottom plate 212 can cooperate with the first connecting member 213a of the adjacent hanging basket unit 213, thereby providing a hermetic connection between the hanging basket bottom plate 212 and the adjacent hanging basket unit 213.

[0057] In other embodiments, the first connecting member 213a of the hanging basket unit 213 can be disposed on a stainless steel plate at the lower edge of the mesh. The second connecting member 213b of the hanging basket unit 213 can be disposed on a stainless steel plate at the upper edge of the mesh. In this case, the first connecting member 213a can be correspondingly disposed on the hanging basket top cover 211, and the second connecting member 213b can be correspondingly disposed on the hanging basket bottom plate 212, thereby similarly achieving a sealed connection between the hanging basket top cover 211, the hanging basket unit 213, and the hanging basket bottom plate 212.

[0058] In a specific implementation, the hanging basket top cover 211 may include: a first top cover portion and a second top cover portion. The first top cover portion may be a convex groove-shaped structural steel with hinges on both sides, and the outer edge of the convex groove-shaped structural steel is arc-shaped. The second top cover portion includes two stainless steel meshes with arc-shaped outer sides and straight inner sides. The stainless steel meshes are located on both sides of the first top cover portion and form a circular hanging basket top cover with the first top cover portion. Holes with a diameter of about 1 mm may be evenly distributed on the stainless steel mesh, and the straight side of the stainless steel mesh may be connected to the first top cover portion by a hinge. The hanging basket can be opened or closed by the second top cover portion.

[0059] In some embodiments, the first connecting piece 213a or the second connecting piece 213b on the hanging basket top cover 211 can be distributed on the second top cover portion and correspond to the position of the connecting piece on the hanging basket unit.

[0060] In a specific implementation, to enhance the mechanical strength of the basket top cover 211, a first support portion may be provided at the edge of the basket top cover 211. The first support portion may be a circular stainless steel structure that protrudes from the second top cover portion toward the basket unit 213, thereby better covering the basket unit 213.

[0061] In a specific implementation, the hanging basket bottom plate 212 may include a first bottom plate portion, a second bottom plate portion and a second support portion. The first bottom plate portion may be realized as a stainless steel plate with hinges on both sides, and the outer edge of the stainless steel plate is arc-shaped. The second bottom plate portion may include two stainless steel meshes with arc-shaped outer sides, straight inner sides and evenly distributed holes of about 1 mm in diameter. The straight sides of the second bottom plate portion are connected to the two sides of the first bottom plate portion by hinges. The second support portion may be a circular stainless steel support structure, and is fixedly connected to the first bottom plate portion by welding. The second support portion protrudes from the second bottom plate portion toward the hanging basket unit 213, so that it can better cover the hanging basket unit 213. In addition, the hanging basket can be opened or closed through the second bottom plate portion.

[0062] In some embodiments, the first connecting member 213a or the second connecting member 213b on the hanging basket bottom plate 212 can be distributed on the second bottom plate portion and correspond to the position of the connecting member on the hanging basket unit.

[0063] The basket can be airtightly connected by connecting parts of the basket top cover 211, the basket bottom plate 212, and the basket unit 213, thereby allowing the basket top cover 211, the basket bottom plate 212, and the basket unit 213 to enclose a cavity that can hold the raw materials to be extracted. The cavity can be opened or closed from the top of the basket via the basket top cover 211. After the basket top cover 211 is opened, the raw materials to be extracted can be placed in the cavity. After the basket top cover 211 is closed, it can be ensured that the raw materials to be extracted are only soaked and tumbled in the cavity. The cavity can be opened or closed at the bottom of the basket via the basket bottom plate 212. After the basket bottom plate 212 is opened, the raw materials extracted in the cavity can be discharged, realizing the slag discharge function. After the basket bottom plate 212 is closed, the cavity can be used again to hold the raw materials to be extracted.

[0064] In a specific implementation, when the volume of the hanging basket is adjustable, the position of the hanging basket within the extraction kettle can be adjustable or fixed. Whether the position of the hanging basket within the extraction kettle is adjustable is not a prerequisite for whether the volume of the hanging basket is adjustable. In other words, even if the volume of the hanging basket is not adjustable, the position of the hanging basket within the extraction kettle can also be set to be adjustable.

[0065] In specific implementations, various methods can be used to achieve adjustable position of the hanging basket in the extraction kettle, which are not limited here.

[0066] In one embodiment of the present invention, referring to Figure 2 The hanging basket assembly further includes a hanging basket connector 22. A first end of the hanging basket connector 22 is connected to the extraction kettle top cover 31, and a second end of the hanging basket connector 22 is connected to the hanging basket 21. The hanging basket connector 22 is used to adjust the position of the hanging basket 21 within the extraction kettle, and the first end of the hanging basket connector 22 is opposite to the second end of the hanging basket connector 22.

[0067] By providing the hanging basket connector 22, the position of the hanging basket 21 in the extraction kettle can be changed, thereby adjusting the immersion amount of the hanging basket 21 to facilitate obtaining an extract with the best flavor.

[0068] Specifically, the hanging basket connecting member 22 may include: a columnar structure and a hanging basket position adjustment structure; the hanging basket position adjustment structure is located on the columnar structure and is used to adjust the position of the hanging basket 21 in the extraction kettle.

[0069] The hanging basket position adjustment structure may be implemented in a variety of ways, which are not limited here, as long as the hanging basket 21 can move up and down along direction A.

[0070] In one embodiment, the columnar structure may be a cylindrical structure; the hanging basket position adjustment structure may include a thread provided on the outer surface of the cylindrical structure; the hanging basket 21 is screwed onto the cylindrical structure through the thread on the outer surface of the cylindrical structure.

[0071] Correspondingly, a first screw hole is provided on the hanging basket top cover 211 of the hanging basket 21 at a position corresponding to the columnar structure, and the first screw hole is adapted to the thread on the outer surface of the cylindrical structure.

[0072] Specifically, the cylindrical structure can be a hollow cylindrical structure, the first end of which can be welded to the extraction kettle top cover 31, and the second end of which can be connected to the hanging basket 21 and extend into the interior of the hanging basket 21. The outer surface of the hollow cylindrical structure is provided with threads, and the length of the threads along the direction A on the outer surface of the hollow cylindrical structure can be set according to the required adjustment requirements of the hanging basket position. For example, the thread length can be set to a range of [1 cm, 100 cm].

[0073] A first screw hole can be provided on the first cover portion of the basket cover 211 at a position corresponding to the hollow cylindrical structure. This first screw hole allows the basket cover 211 to be rotated upward or downward on the hollow cylindrical structure. In this case, compared to a cylindrical structure without threads, the height of the basket within the extraction kettle along direction A is adjustable.

[0074] In another embodiment, the columnar structure may be a rectangular columnar structure; the hanging basket position adjustment structure may include: a plurality of first through holes and a first through hole adapter provided on the rectangular columnar structure; the hanging basket is fixed on the rectangular columnar structure through the first through holes and the first through hole adapter.

[0075] Correspondingly, a support frame can also be provided on the hanging basket top cover 211; the support frame is provided with a second through hole at the position corresponding to the first through hole, and the first through hole adapter passes through the second through hole and the first through hole to fix the support frame on the rectangular columnar structure.

[0076] Specifically, a plurality of first through holes distributed along direction A can be provided on the rectangular columnar structure, and the spacing between adjacent first through holes can be set according to the actual adjustment requirements of the hanging basket. For example, the spacing between adjacent first through holes can be set to 5 cm. The first top cover portion of the hanging basket top cover 211 can be welded with two stainless steel support frames according to the diameter of the first through holes. The two stainless steel support frames are provided with second through holes having a diameter substantially the same as the first through holes, and the two stainless steel support frames can be fitted with opposite sides of the rectangular columnar structure.

[0077] In some embodiments, both the first through-hole and the second through-hole can be screw holes, and the first through-hole adapter can be a screw and a nut. The screw can be passed from one side of the rectangular columnar structure through the second through-hole of a stainless steel support frame, the first through-hole on one side of the rectangular columnar structure, the first through-hole on the other side of the rectangular columnar structure, and the second through-hole of another stainless steel support frame, and then locked with a nut, thereby securing the hanging basket to the rectangular columnar structure. In this case, by adjusting the position of the first through-hole through which the screw passes, the position of the hanging basket on the rectangular columnar structure can be changed, thereby adjusting the height of the hanging basket along direction A within the extraction kettle.

[0078] In some embodiments, the hanging basket assembly may further include a stirring structure 23 . The stirring structure 23 is connected to the second end of the hanging basket connector 22 and extends into the hanging basket 21 for stirring the raw materials to be extracted in the hanging basket 21 .

[0079] Accordingly, the hanging basket assembly may further include a stirring power structure 24. The stirring power structure 24 may be fixed above the extraction kettle top cover 31 to provide stirring power to the stirring structure 23 during the extraction process, so that the stirring structure 23 can stir the raw materials to be extracted back and forth during the extraction process.

[0080] Specifically, the stirring power structure 24 can be set on the extraction kettle top cover 31. The extraction kettle top cover 31 can include groove-shaped structural steel and stainless steel plates located on both sides of the groove-shaped structural steel. The groove-shaped structural steel is located between the two stainless steel plates, and the outer side of the groove-shaped structural steel is arc-shaped and the inner side is straight. The outer side of the stainless steel plate is arc-shaped and the inner side is straight. The straight side of the stainless steel plate is connected to the straight side of the groove-shaped structural steel, and the arc-shaped outer edge of the groove-shaped structural steel and the arc-shaped outer edge of the stainless steel plate together form a circular extraction kettle top cover 31. In this way, the extraction kettle top cover 31 can be covered on the extraction kettle, so that the upper end face of the extraction kettle is sealed.

[0081] In a specific implementation, the stirring power structure 24 can be set on the groove-shaped structural steel of the extraction kettle top cover 31, and a hanging basket lifting and lowering part can be set above the stirring power structure 24, through which the hanging basket lifting and lowering action can be realized during the extraction process.

[0082] In a specific implementation, in addition to the columnar structure and the hanging basket position adjustment structure, the hanging basket connector 22 may also include: a stirring transmission structure. Specifically, the stirring transmission structure may include: a rotatable steel column, a gear assembly, a gear fixing seat and a screw fixing base. Among them, the rotatable steel column can be arranged inside the columnar structure of the hanging basket connector 22. The gear assembly is arranged at the top of the rotatable steel column, and a gear fixing seat is arranged below the gear assembly, and the gear assembly is fixed on the gear fixing seat. The stirring power structure 24 transmits the power required for stirring to the rotatable steel column through the gear assembly, so that the rotatable steel column rotates. The screw fixing base is arranged at the bottom end of the rotatable steel column, and the stirring structure 23 is connected to the rotatable steel column through the screw fixing base. When the rotatable steel column rotates, it will drive the stirring structure 23 to rotate, thereby realizing the stirring of the raw materials.

[0083] Figure 3 This is a schematic diagram of the structure of the extraction kettle in one embodiment of the present invention. Figure 3 The extraction kettle is used to define the extraction space. Specifically, the extraction kettle may include: an extraction kettle top cover 31 (such as Figure 2 ), a tank body 32, an insulating interlayer 33, and a discharge port 34. The tank body 32 may be a cylindrical stainless steel tank with an opening at the top through which the hanging basket can enter the extraction kettle, which is sealed by the extraction kettle top cover 31. Hot or cold water, for example, can be passed through the sidewalls of the tank body 32 as an extraction solvent. The insulating interlayer 32 may be a hollow stainless steel insulating interlayer into which steam can be passed for insulation and heating. The discharge port 34 is located at the lowest point of the tank body 32, through which the extract can be discharged.

[0084] In a specific embodiment, a temperature sensor may be provided within the extraction kettle to detect the temperature within the extraction kettle. The insulating interlayer 32 may have a steam inlet, and a steam proportional valve may be provided at the steam inlet. The temperature sensor may be linked to the steam proportional valve to achieve automatic temperature control.

[0085] Figure 4 and Figure 5 This is a schematic diagram of the structure of an extraction device according to an embodiment of the present invention. Figure 4 and Figure 5 According to the volume of the extraction solvent in the extraction kettle 41, the volume of the hanging basket 42 and the position of the hanging basket in the extraction kettle 41 are adjusted.

[0086] For example, refer to Figure 4When the volume of the extraction solvent is large, the hanging basket 42 can be configured to include three hanging basket units, and the position of the hanging basket 42 in the hanging basket connector 43 can be adjusted upward. The adjusted hanging basket 42 is then lowered into the extraction kettle 41 and the extraction kettle 41 is closed. At this point, the immersion level of the hanging basket 42 in the extraction kettle 41 is at position L2. Next, the power output of the stirring power structure 44 is controlled so that the stirring structure 45 stirs the raw material to be extracted. After the stirring is completed, the extract is obtained through the discharge port of the extraction kettle 41.

[0087] Reference Figure 5 When the volume of the extraction solvent is small, the hanging basket 42 can be configured to include only two hanging basket units, and the position of the hanging basket 42 in the hanging basket connector 43 can be lowered. Afterwards, the adjusted hanging basket 42 is lowered into the extraction kettle 41, and the extraction kettle 41 is covered. At this time, the immersion amount of the hanging basket 42 in the extraction kettle 41 is at position L3.
