Description

Technical Field

[0001] The present invention relates to the technical field of household kitchen appliances, and more particularly to a beverage device with high-pressure vibration extraction and an extraction method thereof. Background Art

[0002] In daily life, people often mix tea leaves, coffee powder, milk tea powder, milk powder, various beverage granules and honey with water to obtain various beverages. In summer, to get a refreshing and cool beverage, cold water is often used for extraction. However, for substances like tea leaves and coffee, cold water extraction takes a long time. For example, coffee extraction with cold water takes 7 to 12 hours. The long extraction time leads to an oxidation reaction between the liquid and oxygen in the air, releasing acidic substances, resulting in a deteriorated taste and volatilization of the aroma.

[0003] In the prior art, such as Chinese invention patent CN202023205195.3: A cold and hot extraction coffee machine, including a control device, a water supply device and a heating device. It is characterized in that the cold and hot extraction coffee machine further includes: an extraction device, which includes a brewing chamber, a cold extraction filter and a hot extraction filter, and the cold extraction filter and the hot extraction filter can be alternately arranged in the brewing chamber; a power mechanism, which includes a driving component outside the brewing chamber and an impeller inside the brewing chamber. When the cold extraction filter is arranged in the brewing chamber for cold extraction, the impeller rotates under the drive of the driving component to drive the liquid in the brewing chamber to circulate and flow to extract the ingredients in the cold extraction filter. Through the driving component outside the brewing chamber and the impeller rotating under the drive of the driving component to drive the liquid in the brewing chamber to circulate and flow to extract the ingredients in the cold extraction filter, that is, by stirring to accelerate the liquid flow to impact the powder particles of the extract. Since the driving component is located outside the brewing chamber, the brewing chamber needs to be provided with a shaft hole corresponding to the driving component, and a sealing component is required between the shaft hole and the driving component to prevent liquid leakage. The long-term rotation of the driving component and the friction of the sealing component result in a decrease in the sealing degree, prone to liquid leakage, leading to damage to the driving component, pollution of the liquid, and poor stability and reliability.

[0004] For another example, in Chinese invention patent CN202220489899.8: A cold extraction device, comprising: a cup assembly, including an outer cup and an inner cup, the inner cup is installed inside the outer cup, a liquid cavity for holding liquid is formed between the inner cup and the outer cup, the object to be brewed is placed in the inner cup, and the bottom of the inner cup communicates with the liquid cavity; a main body assembly, including a main body housing and an air pump installed inside the main body housing, the air pump inlet of the air pump is respectively communicated with external air and the inner cup through pipelines, the air pump outlet of the air pump is respectively communicated with external air and the inner cup through pipelines different from those connecting the air pump inlet, and a plurality of control valves are provided on the pipelines. By switching the operation of the plurality of control valves, a first ventilation pipeline can be formed by sequentially connecting the first pipeline communicating with external air, the air pump, and the inner cup, introducing external air into the inner cup, so that the liquid in the inner cup flows into the liquid cavity, and the object to be brewed in the inner cup is brewed; or a second ventilation pipeline can be formed by sequentially connecting the inner cup, the air pump, and the second pipeline communicating with external air, exhausting the air in the inner cup, so that the liquid in the liquid cavity enters the inner cup to brew the object to be brewed. By pumping out the air in the inner cup with a pump, the air in the atmosphere enters the outer cup, and the liquid in the outer cup flows into the inner cup. On the contrary, when the pump inflates the inner cup, the air in the atmosphere enters the inner cup, the liquid in the inner cup flows into the outer cup, and the air in the outer cup enters the atmosphere. Therefore, the outer cup is always communicated with the atmosphere, and at the same time, only one pump is used for air extraction and inflation. During extraction, the pressure in the inner cup and the outer cup is small, and the extraction is only carried out by repeatedly flowing the liquid through the extract. The liquid cannot penetrate the powder particle core of the extract, and it is necessary to repeatedly switch air extraction and inflation many times. The extraction speed is slow, the extraction is not sufficient, and the repeated entry of air causes the liquid or the extract to undergo an oxidation reaction, making the beverage taste bad and affecting the taste.

[0005] As can be seen from the above patent, the prior art only accelerates extraction in one way, with a slow extraction speed, insufficient extraction, and long-term contact with air, making it more likely to undergo oxidation reactions, resulting in a poor taste of the beverage, a complex structure, and high costs. Therefore, it is necessary to make improvements. Summary of the Invention

[0055] 4.

[0079] The following are only the preferred embodiments of the present invention and do not limit the protection scope of the present invention accordingly.

[0080] A beverage device for high-pressure vibration extraction, such as Figures 1 to 10As shown in the figure, it includes a cup body 1, a base 12 and a lid 2. The lid 2 is closed on the upper part of the cup body 1, the lower part of the cup body 1 is fixedly installed on the base 12, an extraction chamber 11 for containing liquid is arranged inside the cup body 1, a cup body sealing ring 24 for sealing the extraction chamber 11 is arranged between the cup body 1 and the lid 2, a high-pressure extraction device is installed inside the base 12, a vibration extraction device 3 is arranged in the extraction chamber 11, the high-pressure extraction device is provided with a power assembly, a positive pressure air duct and a negative pressure air duct for pumping air and inflating the extraction chamber 11, the first ends of the positive pressure air duct and the negative pressure air duct are respectively connected to the power assembly, and the second ends of the positive pressure air duct and the negative pressure air duct are respectively connected to the extraction chamber 11; the vibration extraction device 3 includes a mounting housing 31, a vibration mechanism 32 and a cartridge 33. The inside of the mounting housing 31 has a closed mounting chamber, the vibration mechanism 32 is installed in the mounting chamber, the upper part of the mounting housing 31 is fixedly installed on the lower part of the lid 2, the cartridge 33 is movably installed on the lower part of the mounting housing 31, a sachet chamber 334 for storing the extract 336 is arranged inside the cartridge 33, a plurality of filter holes 333 are formed in the side wall of the cartridge 33, the sachet chamber 334 is communicated with the extraction chamber 11 through each filter hole 333, and there is a vibration gap 36 between the vibration extraction device 3 and the inner wall of the extraction chamber 11.

[0081] In the present invention, vibration extraction and high-pressure extraction are carried out simultaneously by the vibration extraction device 3 and the high-pressure extraction device. Compared with the traditional single extraction method, the extraction speed is doubled. The traditional pressure extraction method only allows the liquid to flow through the extract, and it needs to exchange air in the atmosphere and in the cup, which is not a sealed space, with a small vacuum force, a small pressure in the extraction chamber 11, and a long extraction time. During the extraction process, the air in the atmosphere will repeatedly enter, resulting in an oxidation reaction of the liquid and affecting the taste of the beverage. Moreover, the traditional extraction requires two nested cups, which are large in volume and small in capacity. In the present invention, the extraction chamber 11 is a sealed chamber. When the power assembly alternately pumps air or inflates the extraction chamber 11, a large pressure difference can be generated. Under high pressure, the extract 336 is squeezed and extracted by the liquid, making it easier for the liquid to repeatedly penetrate the powder particle core of the extract 336, improving the extraction speed, making the extraction more thorough, and having a high extraction concentration; the extraction chamber 11 is a sealed space, and the liquid is not exposed to the air during extraction. At the same time, under high pressure, the number of times of switching between the positive pressure and negative pressure states is reduced, the contact between the liquid and the air is reduced, the oxidation reaction during the extraction process is prevented, and the taste of the beverage is improved; the high-pressure extraction device is arranged on the base 12 at the lower part of the cup body 1, which reduces the center of gravity, eliminates the need for two nested cups, is convenient for cleaning, reduces the volume of the whole machine, has a simple structure and low cost.

[0082] The traditional stirring extraction method uses a mechanical structure for stirring, which has certain requirements for the torque of the motor 321. Prolonged use will wear the seals, resulting in liquid leakage, poor stability and reliability. There are also some that use magnetic fields for stirring, with weak stirring force and unable to stir solid or flaky extracts such as tea bags 336. At the same time, expensive rare earth strong magnets are required as materials, resulting in high costs. In contrast, the present invention drives the cartridge 33 to vibrate through the vibration mechanism 32, thereby accelerating the dissolution and extraction speed of the extract 336. When high-pressure extraction is performed by the high-pressure extraction device, the vibration extraction device 3 also plays a role in stirring the liquid, enabling it to assist the high-pressure extraction device in extraction and further improving the extraction speed. It does not require tools for stirring, is convenient to use, reduces the torque requirements for the motor 321, has a simple structure and low cost; the vibration extraction device 3 is installed on the lid 2, and the inner wall of the cup body 1 is complete, facilitating disassembly and cleaning without cleaning dead ends; the vibration mechanism 32 is installed in the closed installation housing 31, and the liquid will not penetrate into the installation chamber, extending the service life of the whole machine and improving stability and reliability; the extract 336 is placed in the cartridge 33, and the cartridge 33 has a filtering function, and the residue after extraction is retained in the cartridge 33, improving the taste of the beverage without the need for secondary filtration. As Figure 5 shown, in the working state, the cartridge 33 swings radially with the connection between the installation housing 31 and the lid 2 as the fulcrum. The extract 336 in the cartridge 33 improves the extraction speed or accelerates dissolution under vibration, and the cartridge 33 pats the liquid in the extraction chamber 11 during vibration, and also has the function of stirring the liquid, further enabling the molecules separated from the liquid and the extract 336 to fuse.

[0083] Specifically, the high-pressure extraction device includes at least two pumps, a first control valve 51, a second control valve 52 and a plurality of pipelines. The two pumps are connected in series through the corresponding pipelines to form a power assembly. The power assembly is respectively connected to the first control valve 51 and the second control valve 52 through the corresponding pipelines. The first control valve 51 and the second control valve 52 are respectively connected to the atmosphere or nitrogen. The extraction chamber 11 is respectively connected to the first control valve 51 and the second control valve 52 through the corresponding pipelines; a control circuit is also provided inside the base 12, and the control circuit is electrically connected to the two pumps, the first control valve 51 and the second control valve 52 respectively. When extracting, the first control valve 51 and the second control valve 52 work alternately to achieve air extraction or air charging for the extraction chamber 11. The two pumps are connected in series to increase the vacuum degree and positive pressure, reduce the number of switches between positive pressure and negative pressure, and reduce the contact time between the liquid and air, further improving the taste and extraction speed.

[0084] Specifically, the high-pressure extraction device is further provided with a three-way connector 67. The pipelines include a first pipeline 61, a second pipeline 62, a third pipeline 63, a fourth pipeline 64, a fifth pipeline 65 and a sixth pipeline 66. The pumps include a first diaphragm pump 71 and a second diaphragm pump 72. The first control valve 51 and the second control valve 52 are both provided with an external connection port 53, a first air vent 54 and a second air vent 55. The external connection ports 53 of the first control valve 51 and the second control valve 52 are respectively connected to the atmosphere. The first end of the first pipeline 61 is connected to the extraction chamber 11, and the second end of the first pipeline 61 is connected to the three-way connector 67. The first ends of the second pipeline 62 and the third pipeline 63 are respectively connected to the three-way connector 67. The second end of the second pipeline 62 is connected to the first air vent 54 of the first control valve 51. The second end of the third pipeline 63 is connected to the first air vent 54 of the second control valve 52. The first end of the fourth pipeline 64 is connected to the second air vent 55 of the first control valve 51, and the second end of the fourth pipeline 64 is connected to the air inlet of the first diaphragm pump 71. The first end of the fifth pipeline 65 is connected to the second air vent 55 of the second control valve 52, and the second end of the fifth pipeline 65 is connected to the air outlet of the second diaphragm pump 72. The first end of the sixth pipeline 66 is connected to the air outlet of the first diaphragm pump 71, and the second end of the sixth pipeline 66 is connected to the air inlet of the second diaphragm pump 72. By changing the air flow direction through the first control valve 51 and the second control valve 52, the positive pressure and negative pressure in the extraction chamber 11 can be switched without the need for the pumps to be separately connected and controlled, reducing costs. The pumps use diaphragm pumps, which have low noise and small volume.

[0085] An installation bracket 16 is further provided inside the base 12. The middle part of the installation bracket 16 has an installation platform 161. The first diaphragm pump 71 and the second diaphragm pump 72 are respectively fixedly installed at the lower part of the installation platform 161. The first control valve 51, the second control valve 52 and the three-way connector 67 are respectively fixedly installed at the upper part of the installation platform 161. The cartridge 33 is located at the lower part of the extraction chamber 11 and can cover the cartridge 33 even when the liquid contained is less. The high-pressure extraction device is installed on the installation bracket 16 to fix each component to avoid abnormal noise. During the assembly process, the components are first installed on the installation bracket 16, and then they and the installation bracket 16 are installed inside the base 12 together, which is convenient for production and improves production efficiency.

[0086] Specifically, the beverage equipment includes a positive pressure state, a negative pressure state and an initial state.

[0087] In the positive pressure state, such as Figure 8As shown, the first control valve 51 stops working. The external connection port 53 of the first control valve 51 is communicated with the second air vent 55 of the first control valve 51, and the external connection port 53 of the first control valve 51 and the second air vent 55 of the first control valve 51 are respectively relatively isolated from the first air vent 54 of the first control valve 51. The second control valve 52 works. The first air vent 54 of the second control valve 52 is communicated with the second air vent 55 of the second control valve 52, and the first air vent 54 of the second control valve 52 and the second air vent 55 of the second control valve 52 are respectively relatively isolated from the external connection port 53 of the second control valve 52. The first control valve 51, the fourth pipeline 64, the first diaphragm pump 71, the sixth pipeline 66, the second diaphragm pump 72, the fifth pipeline 65, the second control valve 52, the third pipeline 63, the three-way connector 67 and the first pipeline 61 are sequentially communicated to form a positive pressure air duct. The air in the atmosphere enters the extraction chamber 11 from the positive pressure air duct;

[0088] In the negative pressure state, as Figure 7 shown, the second control valve 52 stops working. The external connection port 53 of the second control valve 52 is communicated with the second air vent 55 of the second control valve 52, and the external connection port 53 of the second control valve 52 and the second air vent 55 of the second control valve 52 are respectively relatively isolated from the first air vent 54 of the second control valve 52. The first control valve 51 works. The first air vent 54 of the first control valve 51 is communicated with the second air vent 55 of the first control valve 51, and the first air vent 54 of the first control valve 51 and the second air vent 55 of the first control valve 51 are respectively relatively isolated from the external connection port 53 of the first control valve 51. The first pipeline 61, the three-way connector 67, the second pipeline 62, the first control valve 51, the fourth pipeline 64, the first diaphragm pump 71, the sixth pipeline 66, the second diaphragm pump 72, the fifth pipeline 65 and the second control valve 52 are sequentially communicated to form a negative pressure air duct. The air in the extraction chamber 11 is discharged from the negative pressure air duct to the atmosphere;

[0089] During extraction, it enters the negative pressure state. As Figure 6 shown, in the negative pressure state, the liquid in the material package chamber 334 enters the extraction chamber 11 through each filter hole 333, so that the liquid that has absorbed and fused beverage molecules enters the extraction chamber 11 to mix with the unfused liquid in the extraction chamber 11. At the same time, the extract is pulled, and the powder particles that gather the extract together are dispersed, making it easier for the liquid to penetrate the core of the powder particles. Then it enters the positive pressure state. As Figure 5As shown, under positive pressure, the liquid in the extraction chamber 11 re-enters the sachet chamber 334 through each filtering hole 333, penetrates the powder particle core, and at the same time squeezes the extract, extruding the beverage molecules in the extract into the liquid and then re-entering the negative pressure state, switching alternately 2 to 4 times to complete the extraction. The holding time in the positive pressure state and the negative pressure state is adjusted according to personal taste and concentration, and the number of alternating switches can also be adjusted according to personal taste and concentration to extract beverages suitable for different people's tastes. As Figure 9 shown, when the extraction is carried out, the vibration extraction device 3 continuously vibrates, stirring the liquid while assisting in the extraction.

[0090] In the initial state, both the first control valve and the second control valve 52 stop working. The external connection port 53 of the first control valve 51 is communicated with the second ventilation port 55 of the first control valve 51, and the external connection port 53 of the first control valve 51 and the second ventilation port 55 of the first control valve 51 are respectively relatively blocked from the first ventilation port 54 of the first control valve 51. The external connection port 53 of the second control valve 52 is communicated with the second ventilation port 55 of the second control valve 52, and the external connection port 53 of the second control valve 52 and the second ventilation port 55 of the second control valve 52 are respectively relatively blocked from the first ventilation port 54 of the second control valve 52. The first diaphragm pump 71 and the second diaphragm pump 72 are relatively blocked from the extraction chamber 11 through the first control valve 51 and the second control valve 52; the flow rates of both the first diaphragm pump 71 and the second diaphragm pump 72 are 2 to 7 liters per minute, and the vacuum degrees are both 50 to 70 kPa; when the pressure in the extraction chamber 11 switches from the negative pressure state to the positive pressure state or from the positive pressure state to the negative pressure state, there is a pressure difference, and the pressure difference is 200 to 300 kPa.

[0091] Preferably, the flow rates of both the first diaphragm pump 71 and the second diaphragm pump 72 are 3 to 6 liters per minute, and the vacuum degrees are both 64 kPa. In the negative pressure state, the vacuum degree in the extraction chamber 11 reaches 75 to 85 kPa; in the positive pressure state, the positive pressure in the extraction chamber 11 reaches 120 to 200 kPa. When the pressure in the extraction chamber 11 switches from the negative pressure state to the positive pressure state or from the positive pressure state to the negative pressure state, there is a pressure difference, and the pressure difference is 285 kPa. Therefore, during extraction, the extract is under a pressure of 285 kPa. Under high pressure, the liquid is more likely to repeatedly penetrate the powder particle core of the extract, improving the extraction speed, making the extraction more complete, and having a high extraction concentration. Under high pressure, the number of switches between the positive pressure state and the negative pressure state is reduced to 2 to 4 times. Therefore, the contact time between the liquid and air is reduced, the oxygen content in the extraction chamber 11 is reduced, thereby preventing oxidation reactions and improving the taste. Preferably, the external connection ports 53 of the first control valve 51 and the second control valve 52 are respectively connected to gas cylinders filled with nitrogen, thus completely preventing the liquid from contacting oxygen and avoiding oxidation reactions by 100%.

[0092] Specifically, a vibration damping mechanism is provided between the mounting housing 31 and the lid 2. The mounting housing 31 includes a housing body 311 and a housing cover 312. The housing cover 312 is disposed on the upper end of the housing body 311. A housing sealing ring 314 is provided between the housing cover 312 and the housing body 311. At least one connecting column 313 extends upward from the upper part of the housing cover 312. The lid 2 is provided with at least two connecting holes 21. At least one connecting hole 21 is matched with the connecting column 313. A threaded hole with an upward opening is provided in the central part of the connecting column 313. The connecting column 313 is inserted into the connecting hole 21, and a screw 22 is threadedly connected to the threaded hole; the vibration damping mechanism includes a soft rubber pad 34. The soft rubber pad 34 is disposed between the housing cover 312 and the lid 2. An installation column 341 and a wire passing column 344 corresponding to the connecting hole 21 are provided on the upper part of the soft rubber pad 34. An installation boss 342 is provided on the upper part of the installation column 341. A through-column hole 343 for passing through the connecting column 313 is provided in the central part of the installation column 341. The installation column 341 and the wire passing column 344 are respectively inserted into the corresponding connecting holes 21. The connecting column 313 is inserted into the through-column hole 343, and the installation boss 342 of the installation column 341 protrudes from the top surface of the lid 2 and is in abutting cooperation with the lid 2.

[0093] Long-term vibration of the vibration extraction device 3 may cause the fixation between the mounting housing 31 and the lid 2 to gradually become loose, resulting in the risk of detachment. At the same time, it may cause resonance between the lid 2 and the cup body 1. The vibration damping mechanism forms a soft connection between the vibration extraction device 3 and the lid 2, preventing the generation of resonance, avoiding the detachment of the mounting housing 31 caused by vibration, and improving stability and reliability. The housing body 311 and the housing cover 312 are connected by snap or thread, and sealed by the housing sealing ring 314 to prevent liquid from entering the installation chamber and causing the vibration mechanism 32 to short-circuit, improving reliability and stability. At the same time, it is convenient to install and disassemble the vibration mechanism 32 by disassembling the housing cover 312, which is beneficial to production and maintenance. During installation, first insert the installation column 341 and the wire passing column 344 of the soft rubber pad 34 into the corresponding connecting holes 21 respectively, so that the installation boss 342 protrudes from the top surface of the lid 2 and is in abutting cooperation with the lid 2; preferably, the soft rubber pad 34 is provided with three installation columns 341 and one wire passing column 344, and the corresponding lid 2 is provided with four connecting holes 21, increasing the connection tightness between the mounting housing 31 and the lid 2. Then insert each connecting column 313 of the mounting housing 31 into the through-column hole 343, and finally thread the screw 22 with the through-column hole 343 to complete the installation. As Figure 9 shown, when the vibration mechanism 32 is working, the material cylinder 33 swings radially with the soft rubber pad 34 as the fulcrum.

[0094] Specifically, the vibration mechanism 32 includes a motor 321 and an eccentric block 322. The eccentric block 322 is eccentrically and fixedly mounted on the output shaft 323 of the motor 321. The installation chamber includes an upper chamber 315 and a lower chamber 316. The upper chamber 315 is located above the lower chamber 316. The upper chamber 315 communicates with the lower chamber 316. The diameter of the lower end of the upper chamber 315 is larger than that of the upper end of the lower chamber 316. A stepped portion is formed at the connection between the upper chamber 315 and the lower chamber 316. The motor 321 is fixedly mounted in the upper chamber 315. The lower part of the motor 321 abuts against the stepped portion. The motor 321 is electrically connected to the control circuit. The eccentric block 322 is located in the lower chamber 316. The diameter of the lower part of the housing 311 gradually decreases from top to bottom to form a frustum shape. Since only the relatively small eccentric block 322 needs to be placed in the lower chamber 316, the diameter of the lower part of the housing 311 gradually decreases from top to bottom, compressing the volume of the lower chamber 316, thereby increasing the volume of the extraction chamber 11. The motor 321 drives the output shaft 323 to rotate. Since the central part of the eccentric block 322 deviates from the output shaft 323, the eccentric block 322 makes an eccentric rotational motion, thereby generating an eccentric force and causing vibration. The structure is simple and the cost is low.

[0095] The rotational speed of the motor 321 is 3000 - 7000 revolutions per minute, and the amplitude of the cartridge 33 is 1 - 8 mm. Preferably, the rotational speed of the motor 321 is 4000 - 6000 revolutions per minute, and the amplitude of the cartridge 33 is 3 - 6 mm, obtaining lower noise under the condition of ensuring the extraction speed and the effect of stirring the liquid.

[0096] Specifically, the cartridge 33 includes a barrel body 331 and a barrel cover 332. The barrel cover 332 covers the upper part of the barrel body 331. An annular clamping portion 335 extends outward from the upper edge of the barrel body 331. The barrel cover 332 is fixedly mounted on the lower end face of the mounting housing 31. A clamping mechanism is provided between the cartridge 33 and the mounting housing 31. The clamping mechanism is fixedly mounted on the lower part of the mounting housing 31. The cartridge 33 is snap-connected to the clamping mechanism. The clamping mechanism includes an elastic chuck 35 made of an elastic material. The elastic chuck 35 includes two oppositely arranged clamping claws 351 and two oppositely arranged unlocking portions 352. The included angle between the adjacent clamping claw 351 and the unlocking portion 352 is 90°. The two clamping claws 351 are respectively snap-connected to the annular clamping portion 335. A plurality of filter holes 333 are formed in the side wall of the barrel body 331. As Figure 10 shown, Figure 10 The left elastic chuck 35 in the figure is the state diagram during clamping, Figure 10 The right elastic chuck 35 in the figure is the state diagram during taking. When placing the extract 336 into the cartridge 33, first simultaneously squeeze the two unlocking portions 352 of the elastic chuck 35 inward, as Figure 10As shown in the figure on the right side of the taking state, the elastic chuck 35 is deformed, and the two claws 351 are deformed and bent outward (in the direction indicated by the arrow) to disengage the annular clamping portion 335, thereby removing the barrel 331. The clamping mechanism is an integrated structure with a simple structure and low cost; and the barrel cover 332 is fixed on the mounting shell 31, as shown in FIG. Figure 2 As shown, the extract 336 can be loaded by simply disassembling the barrel body 331 without opening the barrel cover 332 , which makes loading more convenient and quick, and avoids the barrel cover 332 from being lost.

[0097] The number of meshes in the barrel 331 is 500 to 1200. Preferably, the number of meshes in the barrel 331 is 700 to 1000. The barrel 33 also has a filtering function. When extracting bulk tea leaves, the tea residue is retained in the barrel 33 and does not enter the extraction chamber 11. After the extraction is completed, the lid 2 is opened, and the vibration extraction device 3 leaves the extraction chamber 11 along with the lid 2. The tea residue also leaves the extraction chamber 11 along with the barrel 33. The cup body 1 can be directly picked up for drinking without the need for secondary filtration. The liquid is free of residue, which improves the drinking taste. At the same time, the residue will not stick everywhere, making it easy to clean and eliminating dead corners.

[0098] Specifically, a "C"-shaped handle 13 is provided on one side of the cup body 1, the upper part of the handle 13 is fixedly installed on one side of the cup body 1, and the lower part of the handle 13 is fixedly installed on one side of the base 12. A wiring chamber 131 is provided inside the handle 13, and an air hole 111 is provided on the side of the upper part of the extraction chamber 11 corresponding to the handle 13, which passes through the cup body 1. The upper end of the wiring chamber 131 is connected with the air hole 111, and the lower end of the wiring chamber 131 is connected with the interior of the base 12. The pipeline is passed through the wiring chamber 131, and the positive pressure airway and the negative pressure airway are respectively connected with the air hole 111; at least two lower conductive sheets 14 are provided on the upper part of the handle 13, and the two lower conductive sheets 14 reveal the upper end surface of the handle 13. Two lower conductive wires 15 are passed through the wiring chamber 131, and the two lower conductive wires 15 are passed through the wiring chamber 131. The upper ends of the wires 15 are electrically connected to the two lower conductive sheets 14 respectively, and the lower ends of the two lower conductive wires 15 are electrically connected to the control circuit respectively. Two upper conductive sheets 25 are provided on one side of the lid 2. The two upper conductive sheets 25 are electrically connected to the vibration mechanism 32 through upper conductive wires 26. The two upper conductive sheets 25 are exposed from the lower end surface of the lid 2. The shell 312 and the threading column 344 are respectively provided with threading holes 27. The two threading holes 27 are aligned in the vertical direction. One end of the two upper conductive wires 26 is electrically connected to the two upper conductive sheets 25 respectively, and the other ends of the two upper conductive wires 26 are respectively passed through the two threading holes 27 and electrically connected to the vibration mechanism 32. When the lid 2 is closed on the cup body 1, the two upper conductive sheets 25 are electrically connected to the two lower conductive sheets 14 respectively.

[0099] Since the vibration extraction device 3 is installed on the lid 2, the weight of the lid 2 has been increased. Installing the control circuit inside the base 12 reduces the weight of the lid 2 while improving the stability of the cup body 1. The handle 13 facilitates the grasping of the cup body 1 while hiding the lower conductive wire 15. The two lower conductive sheets 14 respectively correspond to the positive and negative poles of the motor 321. Similarly, the two upper conductive sheets 25 respectively correspond to the positive and negative poles of the motor 321. The two lower conductive sheets 14 or the two upper conductive sheets 25 are elastic conductive sheets, thereby increasing the contact tightness. The wire threading post 344 of the soft rubber pad 34 is inserted into the connection hole 21, and the wire threading hole 27 on the shell cover 312 is sealed by the soft rubber pad 34. The two upper conductive wires 26 sequentially pass through the wire threading hole 27 of the soft rubber pad 34 and the wire threading hole 27 on the shell cover 312 and are electrically connected to the motor 321, ensuring the tightness of the installation chamber and further preventing liquid from entering the installation chamber.

[0100] The high-pressure extraction device is installed inside the base 12, which lowers the center of gravity, making the whole more stable and not easily toppled. In order to prevent the liquid from contacting the pump, the air hole 111 needs to be opened at the upper part of the cup body 1. Therefore, the first pipeline 61 is exposed outside, affecting the aesthetics. By connecting the cup body 1 and the base 12 with the "C"-shaped handle 13, the first pipeline 61 is hidden in the wire routing chamber 131 of the handle 13, with higher aesthetics and being convenient for grasping, improving the usability.

[0101] The lid 2 is also provided with a handle 28. One end of the handle 28 extends downward with a wiring part 281. The handle 28 is fixedly installed on the upper part of the lid 2. The inner side of the wiring part 281 fits against the side wall of the lid 2. The inside of the handle 28 is provided with a disassembly chamber 282. The two upper conductive wires 26 are accommodated in the disassembly chamber 282. The two upper conductive sheets 25 are fixedly installed on the wiring part 281 and expose the lower end face of the wiring part 281. Since the handle 13 is located on one side of the cup body 1 and the two lower conductive sheets 14 are relatively located outside the cup body 1, the two upper conductive sheets 25 are fixedly installed on the wiring part 281 located outside the lid 2, aligning the two upper conductive sheets 25 with the two lower conductive sheets 14 respectively, reducing the wall thickness of the lid 2, reducing the weight and the cost.

[0102] Specifically, the high-pressure extraction device is further provided with a liquid level sensing device for detecting the liquid level of the extraction chamber 11. The liquid level sensing device includes at least two liquid level sensing electrodes 81. The two liquid level sensing electrodes 81 are respectively electrically connected to the control circuit through liquid level conducting wires 82. The two liquid level sensing electrodes 81 are arranged on the same horizontal plane and are relatively spaced apart. The two liquid level sensing electrodes 81 are respectively located below the air holes 111. The liquid level conducting wires 82 are arranged in the wire routing chamber 131. When the liquid conducts the two liquid level sensing electrodes 81, the control circuit receives a full water control signal. By using the conductivity of the liquid, when the water level does not reach the height of the two liquid level sensing electrodes 81, the two liquid level sensing electrodes 81 are insulated by air. When the water level is higher than the height of the two liquid level sensing electrodes 81, the liquid conducts the two liquid level sensing electrodes 81, thereby sending a full water control signal to the control circuit, avoiding the liquid from entering the pump through the air holes 111 and the first pipeline 61. The structure of the liquid level sensing electrode 81 is simple, with low cost and high reliability. After the beverage equipment is turned on, the control circuit first checks whether it receives a full water control signal. After determining that there is no full water control signal, it can be started for extraction. After the extraction is completed, it is switched back to the initial state to prevent the liquid from accidentally entering the pump when being poured out.

[0103] A control button 41 and a status display unit 42 are installed inside the wire routing chamber 131 or the base 12. The control button 41 and the status display unit 42 are respectively exposed on the outer side surface of the handle 13 or the outer side surface of the base 12. The control button 41 and the status display unit 42 are respectively electrically connected to the control circuit. A power supply interface 43 and / or a power supply battery are further arranged inside the base 12. The power supply interface 43 is fixedly installed on the base 12 and is electrically connected to the control circuit. The power supply battery is fixedly installed inside the base 12 and is electrically connected to the control circuit. The control circuit is provided with a strong flavor mode and a light flavor mode. In the strong flavor mode, the extraction time is relatively longer, and the number of times of switching between the positive pressure state and the negative pressure state is relatively more. In the light flavor mode, the extraction time is relatively shorter, and the number of times of switching between the positive pressure state and the negative pressure state is relatively less, so as to obtain beverages with different concentrations and tastes. The strong flavor mode or the light flavor mode is selected and started through the control button 41, and at the same time, the working state of the beverage equipment is reflected through the status display unit 42. The status display unit 42 is selected from an LED lamp or a display screen, and the display screen can also have a touch function to replace the control button 41 for control. A power supply interface 43 is further arranged inside the base 12. The power supply interface 43 is fixedly installed on the base 12 and is electrically connected to the control circuit to supply power to the control circuit through an external power supply to supply power to the motor 321. Preferably, a power supply interface 43 and a power supply battery are further arranged inside the base 12. The power supply battery is fixedly installed inside the base 12 and is electrically connected to the control circuit. When the power supply battery is powered, it supplies power to the control circuit without an external power supply and can be carried around and used. When the power supply battery runs out of power, an external power supply is connected through the power supply interface 43 to supply power to the control circuit and charge the power supply battery at the same time.

[0104] The outer side surface of the upper part of the cup body 1 is provided with an external thread, the inner wall of the lid 2 is provided with an internal thread, the lid 2 is threadedly connected to the cup body 1, a sealing groove 23 is arranged at the position of the lid 2 corresponding to the upper edge of the cup body 1, a cup body sealing ring 24 is arranged in the sealing groove 23, and the upper edge of the cup body 1 abuts and cooperates with the cup body sealing ring 24 to realize a closed extraction chamber 11. The cup body 1 and the lid 2 are sealed by the cup body sealing ring 24 to form a closed extraction chamber 11. When extracting, it prevents liquid from splashing outside the cup body 1 and prevents contact with oxygen in the atmosphere for a long time during extraction, preventing oxidation and improving the taste of the beverage.

[0105] An extraction method for high-pressure vibration extraction includes the following steps:

[0106] Feeding step: Open the lid 2 and disassemble the barrel body 331, put the extract 336 into the sachet chamber 334, reinstall the barrel body 331 and inject liquid into the extraction chamber 11, and then cover the lid 2 on the cup body 1; the extract 336 always remains in the sachet chamber 334, playing a filtering role and being completely disassemblable for easy cleaning.

[0107] Full water detection step: The control circuit checks whether it receives a full water control signal. When receiving the full water control signal, the control circuit switches the beverage device to the initial state and issues a full water alarm through the status display unit 42; when extracting, it is preferred to determine whether the water level is higher than the maximum value first to prevent liquid from entering the pump and improve stability and reliability.

[0108] Select the strong mode or the light mode through the control button 41 or the touch screen. When set to the strong mode, the control circuit executes the strong extraction sub-step. The control circuit starts the motor 321, the first diaphragm pump 71, the second diaphragm pump 72 and the first control valve 51, so that the beverage device switches to the negative pressure state. The first control valve 51 stops working after 2 minutes and at the same time starts the second control valve 52, so that the beverage device switches to the positive pressure state. After the second control valve 52 starts for 2 minutes, it stops working and at the same time starts the first control valve 51, so that the beverage device switches to the negative pressure state again. After the first control valve 51 works for 3 minutes, the motor 321, the first diaphragm pump 71, the second diaphragm pump 72 and the first control valve 51 are stopped at the same time, so that the beverage device switches to the initial state; the extraction time reaches 7 minutes, and the positive pressure state and the negative pressure state are switched 2 times. While ensuring the extraction concentration, the number of times of switching between the positive and negative pressure states is reduced, that is, the extraction speed and concentration are improved, and the air contact time is reduced, ensuring the taste of the beverage.

[0109] When set to the light mode, the control circuit executes the light extraction sub-step. The control circuit starts the motor 321, the first diaphragm pump 71, the second diaphragm pump 72 and the first control valve 51, so that the beverage device switches to the negative pressure state. The first control valve 51 stops working after 1 minute and at the same time starts the second control valve 52, so that the beverage device switches to the positive pressure state. After the second control valve 52 starts for 1 minute, it stops working and at the same time starts the first control valve 51, so that the beverage device switches to the negative pressure state again. After the first control valve 51 works for 2 minutes, the motor 321, the first diaphragm pump 71, the second diaphragm pump 72 and the first control valve 51 are stopped at the same time, so that the extraction chamber 11 switches to the initial state. The extraction time is shortened to 4 minutes, and the switching between the positive pressure state and the negative pressure state is 2 times, reducing the extraction time and controlling the extraction concentration to meet the people with a light taste, and the applicable population is wider.
