Description

Technical Field

[0001] This invention belongs to the field of vinegar extraction technology, and more specifically, relates to a novel rapid detection device for vinegar age. Background Technology

[0002] Vinegar aging test involves analyzing the physicochemical indicators (such as total acid content and concentration of flavor substances) or sensory characteristics of vinegar to accurately determine the fermentation and aging period of vinegar. The accuracy of the test results is directly related to the quality grading of vinegar products.

[0003] A search of Chinese patent publication number "CN108827715B" reveals "a liquid sampling device." This device employs a dual-power system of a plunger pump and a peristaltic pump, which can quickly transfer liquid from a cup to the plunger pump, shortening the sampling time. A first pressure sensor coordinates the speeds of the peristaltic pump and the plunger pump. The peristaltic pump uses a PWM duty cycle for adjustment, ensuring that the plunger pump is always under a slightly positive pressure. This not only accelerates the liquid extraction speed and saves extraction time but also prevents air bubbles from forming inside the plunger pump, improving sampling accuracy.

[0004] Based on the above search and existing technology findings, the aforementioned patent has certain defects: When using this device, since multiple batches of vinegar need to be continuously sampled and analyzed in batch testing of vinegar age, the device can only complete a single sampling operation. After each sampling, it is necessary to manually disassemble and replace the container with a new one. This is not only cumbersome and involves waiting intervals, resulting in low efficiency of continuous sampling, but also may cause cross-contamination of different batches of vinegar due to operational errors when manually switching containers, making it inconvenient. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a novel rapid vinegar age detection device.

[0006] A novel rapid vinegar age detection device includes a support, a chassis on the inner side of the support, a housing on the upper end of the chassis, a power supply module and a control module inside the housing, and a vertical mounting beam and a horizontal mounting beam fixedly installed on the inner wall of the chassis.

[0007] Preferably, the lower end of the horizontal mounting beam is provided with a replacement structure, which can automatically replace the container after the vinegar is extracted; The replacement structure includes a rotating shaft rotatably mounted on a horizontal mounting beam. A dial is fixedly mounted on the circumferential surface of the rotating shaft. A flat-bottomed shaft is rotatably mounted on the lower end of the horizontal mounting beam. The circumferential surface of the flat-bottomed shaft has four equally divided grooved wheels that are adapted to the dial. Arc-shaped electromagnets are provided on the four side walls of the flat-bottomed shaft. A crescent-shaped container is magnetically connected to the side wall of the arc-shaped electromagnets. The crescent-shaped container is slidably mounted to the chassis. An electric push rod is fixedly mounted on the side wall of the vertical mounting beam. A circular electromagnet is provided on the output shaft of the electric push rod. The circular electromagnet is adapted to the top of the crescent-shaped container. A first through slot is formed inside the chassis. A rubber retaining ring is provided on the inner wall of the first through slot. When no external force is applied, the rubber retaining ring can hold the crescent-shaped container on the chassis. During use, the operator activates the electric push rod through the control module. The output shaft of the electric push rod drives the circular electromagnet to descend and magnetically fix the crescent-shaped container. At the same time, the arc-shaped electromagnet attached to the crescent-shaped container is de-energized. Then, the output shaft of the electric push rod continues to extend, moving the crescent-shaped container down through the first through slot. The limiting effect of the rubber retaining ring on the crescent-shaped container is released when no external force is applied, allowing the crescent-shaped container to be immersed in the vinegar solution. After reaching the appropriate volume, the electric push rod retracts, and the crescent-shaped container returns to the inside of the chassis. At this time, the previously de-energized arc-shaped electromagnet is energized and attracts the crescent-shaped container, the circular electromagnet is de-energized, and the electric push rod returns to its limit position, completing a single vinegar sample collection.

[0008] Preferably, the replacement structure is equipped with a pneumatic structure, which can drive the replacement structure to automatically replace the container after extracting the vinegar. The pneumatic structure includes a piston cylinder threaded onto the side wall of an electric push rod. A piston rod is slidably mounted inside the piston cylinder, and a connecting rod is fixedly mounted between the end of the piston rod and the output shaft of the electric push rod. A first one-way outlet valve and a one-way inlet valve are respectively provided on the top of the piston cylinder. An air tank is provided at the upper end of the horizontal mounting beam. A first solenoid valve and a second solenoid valve are respectively provided at the upper end of the horizontal mounting beam. The second solenoid valve is fixedly mounted above the first solenoid valve. A first air pipe is fixedly connected between the inlet of the first solenoid valve and the outlet of the air tank. A rotary cylinder is provided at the upper end of the horizontal mounting beam. A second air pipe is fixedly connected between the outlet of the first solenoid valve and the interface of the rotary cylinder. The output shaft of the rotary cylinder is fixedly mounted to a rotating shaft. The first one-way outlet valve... A third air pipe is fixedly connected to the air inlet of the gas storage tank, and a fourth air pipe is fixedly connected to the air inlet of the second solenoid valve and the air outlet of the gas storage tank. When the output shaft of the electric push rod descends, it drives the piston rod to slide downward in the piston cylinder through the connecting rod. The piston cylinder draws in air through the one-way air inlet valve. When the output shaft of the electric push rod is reset, the piston rod squeezes the internal air. The air is transported to the gas storage tank for storage through the first one-way air outlet valve and the third air pipe. When the crescent-shaped container is sampled and reset, the first solenoid valve is energized. Part of the gas in the gas storage tank is discharged into the rotary cylinder through the first air pipe, the first solenoid valve, and the second air pipe. The rotary cylinder drives the rotating shaft and the dial to rotate one revolution. Through the four equally divided grooved wheel, it drives the flat bottom shaft and the arc electromagnet to rotate 90 degrees, so that the flat bottom shaft rotates as a whole. The new crescent-shaped container moves to the top of the first through slot, realizing automatic container replacement.

[0009] Preferably, the replacement structure is provided with a driven premixing structure, which can automatically stir the vinegar in the container. The driven premixing structure is driven by a pneumatic structure. The driven premixing structure includes an air slip ring located on the outside of a flat-bottomed shaft. A first connector is located at the fixed ring of the air slip ring, and multiple second connectors are located at the moving ring of the first connector. A fifth air pipe is fixedly connected between the outlet of the second solenoid valve and the first connector. Multiple fixing plates are fixedly mounted on the upper end of the flat-bottomed shaft. A rotating rod is mounted on the side wall of each fixing plate via a torsion spring bearing. A fixing ring is fixedly mounted at the end of the rotating rod. An inner ring is fixedly mounted inside the fixing ring. A ring frame is symmetrically arranged inside the inner ring. A small impeller is rotatably mounted between the ring frames. A mixing main shaft is fixedly mounted at the lower end of the small impeller. The mixing main shaft is rotatably mounted to the inner ring and is located inside a crescent-shaped container. An air outlet groove is formed through the lower side of the inner ring's circumferential surface. A sixth air pipe is fixedly connected between the second connector and the inner ring. The sixth gas pipe is flexible. During the rotation of the flat-bottomed shaft, it synchronously drives the driven premixing structure to rotate, ensuring that the driven premixing structure precisely corresponds to the current crescent-shaped container and avoiding cross-interference. After the crescent-shaped container is sampled and reset to the chassis, the second solenoid valve is energized. Part of the gas in the gas storage tank is transported to the first joint of the gas slip ring through the fourth gas pipe, the second solenoid valve, and the fifth gas pipe. Then, it is discharged into the inner ring through the second joint and the sixth gas pipe. When the gas is discharged through the gas outlet groove of the inner ring, it impacts the small impeller between the ring frames, driving the small impeller to rotate and driving the mixing main shaft to rotate. The mixing main shaft stirs the vinegar inside the crescent-shaped container. When the crescent-shaped container needs to be removed, the fixed ring is rotated through the shell notch, driving the rotating rod to rotate at the torsion spring bearing of the fixed plate, thereby driving the inner ring and auxiliary structures to rotate, causing the mixing main shaft to detach from the crescent-shaped container. Then, the arc-shaped electromagnet is de-energized, and the crescent-shaped container can be removed.

[0010] Preferably, the chassis is equipped with a negative pressure recovery structure, which can recover the vinegar liquid dropped from the container. The negative pressure recovery structure is driven by a pneumatic structure. The negative pressure recovery structure includes a trough that extends through the bottom of a chassis. A bottom sleeve is fixedly installed at the lower end of the chassis and is fixedly installed to the inner wall of a first through groove. A second through groove extends through the bottom sleeve and is parallel to the first through groove. A first threaded pipe cap is provided at the lower end of a rubber retaining ring. A seventh air pipe is fixedly connected to a one-way air inlet valve. A branch air inlet pipe is provided on the circumferential surface of the seventh air pipe. A connector is fixedly connected between the end of the seventh air pipe and the bottom sleeve. A second threaded pipe cap is provided on the circumferential surface of the seventh air pipe. A second one-way air outlet valve is provided inside the seventh air pipe and is located on the second threaded pipe. Inside the lid, after sampling, the vinegar attached to the crescent-shaped container drips through the groove of the base plate into the inside of the bottom sleeve, completing the initial drip recovery. At the same time, when the piston cylinder draws air through the one-way air inlet valve, the seventh air pipe and the branch air inlet pipe, part of the negative pressure generated is transmitted to the connector through the seventh air pipe. The connector indirectly transmits the negative pressure to the surface of the base plate through the groove, which helps to adsorb the residual vinegar on the base plate into the inside of the bottom sleeve. Due to the negative pressure generated by the connector, some vinegar accumulates at the second threaded pipe cap. The second one-way air outlet valve inside the seventh air pipe can prevent the liquid from flowing back into the seventh air pipe. When cleaning is required, the second threaded pipe cap and the first threaded pipe cap can be opened to collect the vinegar in a unified manner.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In this invention, by setting a replacement structure, the automatic and convenient replacement of the new container after vinegar extraction can be achieved. After sampling, there is no need for manual disassembly and placement of the new container. A pneumatic structure drives a rotary cylinder, which in turn rotates the shaft and dial. With the help of the matching relationship between the four-slotted wheel and the dial, the flat-bottomed shaft and the arc-shaped electromagnet on the side wall rotate 90 degrees, so that the crescent-shaped containers preset around the flat-bottomed shaft automatically move to the top of the first through slot, completing the container switching preparation. The entire process requires no manual intervention, reducing the tedious steps of manual operation, avoiding the waiting gap when manually switching containers, and greatly improving the efficiency of continuous sampling. It is especially suitable for batch sampling scenarios and reduces the cost of sampling. This design reduces the workload of staff. During the replacement process, each crescent-shaped container is magnetically fixed by a dedicated arc-shaped electromagnet. Only the corresponding container participates in the sampling operation, while other containers remain in standby and isolated from the sampling area. When switching containers, the flat-bottomed shaft drives the arc-shaped electromagnet and the crescent-shaped container to rotate as a whole, avoiding direct contact between different containers. In addition, the magnetic switching between the circular and arc-shaped electromagnets during sampling ensures the stability of the container's position during sampling, resetting, and replacement, preventing the mixing of different batches of vinegar due to container tilting or leakage. This greatly reduces the path of cross-contamination and ensures the accuracy of the sampling results and the purity of the vinegar.

[0012] In this invention, a pneumatic structure is incorporated. When the output shaft of the electric push rod descends, it drives the piston rod to slide downwards within the piston cylinder via a connecting rod. This allows the piston cylinder to draw in air through a one-way inlet valve. When the electric push rod returns to its original position, the piston rod compresses the internal air, which is then transported to the storage tank via a first one-way outlet valve and a third air pipe. This eliminates the need for an external air source, as the air source is simultaneously stored during the sampling process, achieving self-sufficiency in power. Furthermore, through the independent control of the first and second solenoid valves, the compressed air in the storage tank can output power to different structures, enabling multiple structures to share a single pneumatic power system. The solenoid valves precisely control the airflow direction and on / off state, ensuring the timing of actions of each structure is matched. This guarantees a smooth connection between the entire process of sampling, container changing, stirring, and recycling. Moreover, the storage tank stores sufficient compressed air to ensure adequate power for subsequent actions after a single sampling, preventing process interruptions due to insufficient power, enhancing the continuous operation capability of the device, and adapting to batch sampling scenarios.

[0013] In this invention, by setting a driven premixing structure, automated and efficient stirring of vinegar solution after sampling can be achieved. After sampling, the gas storage tank of the pneumatic structure delivers gas to the first joint of the air slip ring through the second solenoid valve and the fifth air pipe. The gas is discharged into the inner ring through the second joint and the flexible sixth air pipe. When the gas is ejected through the gas outlet groove, it impacts the small impeller between the ring frames, driving the mixing main shaft to rotate inside the crescent-shaped container. The stirring of vinegar solution can be completed without an additional power source, avoiding the deviation of the test results caused by the stratification of the components of the vinegar solution, ensuring the uniformity and representativeness of the sample. Moreover, the structure rotates synchronously with the flat-bottomed shaft of the replacement structure, so that the mixing main shaft always corresponds to the crescent-shaped container of the current sampling and does not come into contact or interfere with other containers to be used. This blocks the path of cross-contamination between different batches of vinegar solution from the stirring stage.

[0014] In this invention, when the crescent-shaped container needs to be removed, the rotating ring is rotated through the notch in the shell, which drives the rotating rod to rotate at the torsion spring bearing on the fixed plate. This causes the inner ring and the mixing shaft to rotate synchronously and disengage from the container. The crescent-shaped container can be removed without disassembling complex parts. The torsion spring bearing ensures that the mixing shaft automatically resets after disengagement, guaranteeing accurate positioning for subsequent sampling and stirring.

[0015] In this invention, by setting a negative pressure recovery structure, after the crescent-shaped container is sampled, the vinegar liquid attached to its surface drips naturally into the bottom sleeve through the trough at the bottom of the chassis, completing the initial recovery. At the same time, the piston cylinder of the pneumatic structure generates negative pressure when it draws air through the one-way air inlet valve, the seventh air pipe, and the branch air inlet pipe. This negative pressure is transmitted to the connector through the seventh air pipe, and then indirectly conducted to the surface of the chassis through the trough, actively adsorbing the residual vinegar liquid on the chassis to the bottom sleeve. This solves the problem that manual cleaning is difficult to completely remove residual liquid, greatly improves the recovery coverage, avoids the waste of vinegar liquid, and by setting a second one-way air outlet valve, when the negative pressure generated at the connector causes some vinegar liquid to accumulate at the second threaded pipe cap, it can effectively prevent the liquid from flowing back to the seventh air pipe and other components of the pneumatic structure.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Please see Figure 1 - Figure 12 The present invention provides a novel vinegar age rapid detection device, including a support 11, a chassis 13 provided on the inner side of the support 11, a housing 12 provided on the upper end of the chassis 13, a power supply module and a control module respectively provided inside the housing 12, and a vertical mounting beam 14 and a horizontal mounting beam 15 respectively fixedly installed on the inner wall of the chassis 13.

[0020] A replacement structure is provided at the lower end of the horizontal mounting beam 15. This structure allows for automatic replacement of the container after vinegar extraction. The replacement structure includes a rotating shaft 16, which is rotatably mounted on the horizontal mounting beam 15. A dial 17 is fixedly mounted on the circumferential surface of the rotating shaft 16. A flat-bottomed shaft 18 is rotatably mounted at the lower end of the horizontal mounting beam 15. The circumferential surface of the flat-bottomed shaft 18 is provided with four equally spaced grooved wheels 19, which are adapted to the dial 17. Arc-shaped electromagnets 21 are provided on the four side walls of the flat-bottomed shaft 18. A crescent-shaped container 22 is magnetically connected to the wall and is slidably installed on the chassis 13. An electric push rod 23 is fixedly installed on the side wall of the vertical mounting beam 14. The output shaft of the electric push rod 23 is equipped with a circular electromagnet 24, which is adapted to the top of the crescent-shaped container 22. A first through slot 25 is opened through the inside of the chassis 13. A rubber retaining ring 26 is provided on the inner wall of the first through slot 25. The rubber retaining ring 26 can keep the crescent-shaped container 22 on the chassis 13 when no external force is applied. By setting up a replacement structure, the automatic and convenient replacement of the new container after vinegar extraction can be achieved. After sampling, there is no need for manual disassembly and placement of the new container. A pneumatic structure drives the rotary cylinder 37, which in turn rotates the rotating shaft 16 and the dial 17. With the help of the matching relationship between the four-slotted wheel 19 and the dial 17, the flat-bottomed shaft 18 and the arc-shaped electromagnet 21 on the side wall rotate 90 degrees, so that the crescent-shaped containers 22 preset around the flat-bottomed shaft 18 automatically move to the top of the first through slot 25, completing the container switching preparation. The whole process does not require manual intervention, reducing the tedious steps of manual operation, avoiding the waiting gap when manually switching containers, and greatly improving the efficiency of continuous sampling. It is especially suitable for batch sampling scenarios and reduces the cost of sampling. This reduces the workload of staff. During the replacement process, each crescent-shaped container 22 is magnetically fixed by a dedicated arc-shaped electromagnet 21. Only the corresponding container participates in the sampling operation during the sampling process, while other containers remain in standby and isolated from the sampling area. When switching containers, the flat-bottomed shaft 18 drives the arc-shaped electromagnet 21 and the crescent-shaped container 22 to rotate as a whole, avoiding direct contact between different containers. In addition, the magnetic switching between the circular electromagnet 24 and the arc-shaped electromagnet 21 during sampling ensures the stability of the container's position during sampling, resetting, and replacement, avoiding mixing of different batches of vinegar due to container tilting or leakage. This greatly reduces the path of cross-contamination and ensures the accuracy of the sampling results and the purity of the vinegar.

[0021] The replacement structure is equipped with a pneumatic mechanism that drives the replacement structure to automatically replace the container after extracting the vinegar. The pneumatic mechanism includes a piston cylinder 27, which is threaded onto the side wall of the electric push rod 23. A piston rod 28 is slidably installed inside the piston cylinder 27. A connecting rod 55 is fixedly installed between the end of the piston rod 28 and the output shaft of the electric push rod 23. The top of the piston cylinder 27 is equipped with a first one-way exhaust valve 29 and a one-way intake valve 31. An air storage tank 32 is located at the upper end of the horizontal mounting beam 15. A first solenoid valve 33 and a second solenoid valve 34 are also located at the upper end of the horizontal mounting beam 15. The second solenoid valve 34 is fixedly installed above the first solenoid valve 33. The air inlet of the first solenoid valve 33 is fixedly connected to the air outlet of the air tank 32 by a first air pipe 35. A rotary cylinder 37 is provided at the upper end of the horizontal mounting beam 15. The air outlet of the first solenoid valve 33 is fixedly connected to the interface of the rotary cylinder 37 by a second air pipe 36. The output shaft of the rotary cylinder 37 is fixedly installed to the rotating shaft 16. The first one-way air outlet valve 29 is fixedly connected to the air inlet of the air tank 32 by a third air pipe 38. The air inlet of the second solenoid valve 34 is fixedly connected to the air outlet of the air tank 32 by a fourth air pipe 39. By setting up a pneumatic structure, when the output shaft of the electric push rod 23 descends, the connecting rod 55 drives the piston rod 28 to slide downward in the piston cylinder 27, causing the piston cylinder 27 to draw in air through the one-way air inlet valve 31. When the electric push rod 23 returns to its original position, the piston rod 28 compresses the internal air, which is then transported to the air storage tank 32 for storage through the first one-way air outlet valve 29 and the third air pipe 38. No additional external air source is required; the air source is stored synchronously with the sampling action, achieving self-sufficiency in power. Furthermore, through the independent control of the first solenoid valve 33 and the second solenoid valve 34, the compressed air in the air storage tank 32 can output power to different structures, enabling multiple structures to share a single pneumatic power system. The solenoid valves precisely control the airflow direction and on / off state, ensuring that the timing of each structure's actions is matched, guaranteeing a smooth connection of the entire process of sampling, container changing, stirring, and recycling. Moreover, the air storage tank 32 can store a sufficient amount of compressed air, ensuring sufficient power for subsequent actions after a single sampling, avoiding process interruptions due to insufficient power, improving the continuous operation capability of the device, and adapting to batch sampling scenarios.

[0022] The replacement structure includes a driven premixing structure, which automatically stirs the vinegar solution in the container. This driven premixing structure is pneumatically driven and includes a slip ring 41 located on the outside of the flat-bottomed shaft 18. The fixed ring of the slip ring 41 has a first connector 42, and the moving ring of the first connector 42 has multiple second connectors 43. A fifth air pipe 44 is fixedly connected between the outlet of the second solenoid valve 34 and the first connector 42. Multiple fixing plates 45 are fixedly mounted on the upper end of the flat-bottomed shaft 18, and torsion spring bearings are mounted on the side walls of the fixing plates 45. A rotating rod 46 is provided, and a fixed ring 47 is fixedly installed at the end of the rotating rod 46. An inner ring 48 is fixedly installed inside the fixed ring 47. A ring frame 49 is symmetrically provided inside the inner ring 48. A small impeller 51 is rotatably installed between the ring frames 49. A mixing main shaft 52 is fixedly installed at the lower end of the small impeller 51. The mixing main shaft 52 is rotatably installed with the inner ring 48. The mixing main shaft 52 is located inside the crescent-shaped container 22. An air outlet groove 53 is opened through the inner ring 48 on the circumferential surface near the bottom. A sixth air pipe 54 is fixedly connected between the second connector 43 and the inner ring 48. The sixth air pipe 54 is flexible. By setting a driven premixing structure, automated and efficient stirring of vinegar solution after sampling can be achieved. After sampling, the gas storage tank 32 of the pneumatic structure delivers gas to the first connector 42 of the air slip ring 41 through the second solenoid valve 34 and the fifth air pipe 44. The gas is discharged into the inner ring 48 through the second connector 43 and the flexible sixth air pipe 54. When the gas is ejected through the gas outlet 53, it impacts the small impeller 51 between the ring frame 49, driving the mixing main shaft 52 to rotate inside the crescent-shaped container 22. The stirring of vinegar solution can be completed without an additional power source, avoiding the deviation of the test results caused by the stratification of components in the vinegar solution, ensuring the uniformity and representativeness of the sample. Moreover, the structure rotates synchronously with the flat bottom shaft 18 of the replacement structure, so that the mixing main shaft 52 always corresponds to the crescent-shaped container 22 of the current sampling, and does not come into contact or interfere with other containers to be used. The path of cross-contamination between different batches of vinegar solution is blocked from the stirring stage. When the crescent-shaped container 22 needs to be removed, the fixed ring 47 is rotated through the notch in the housing 12, which drives the rotating rod 46 to rotate at the torsion spring bearing of the fixed plate 45. This causes the inner ring 48 and the mixing shaft 52 to rotate synchronously and disengage from the container. The crescent-shaped container 22 can be removed without disassembling complex parts. The torsion spring bearing allows the mixing shaft 52 to automatically reset after disengagement, ensuring accurate positioning for subsequent sampling and stirring.

[0023] The chassis 13 is equipped with a negative pressure recovery structure, which can recover vinegar liquid dropped from the container. The negative pressure recovery structure is driven by a pneumatic structure and includes a trough 65, which is opened through the bottom of the chassis 13. A bottom sleeve 56 is fixedly installed at the lower end of the chassis 13. The bottom sleeve 56 is fixedly installed on the inner wall of the first through groove 25. A second through groove 57 is opened through the bottom sleeve 56 and is parallel to the first through groove 25. A first threaded pipe cap 58 is provided at the lower end of the rubber retaining ring 26. A seventh air pipe 59 is fixedly connected to the one-way air inlet valve 31. A branch air inlet pipe 61 is provided on the circumferential surface of the seventh air pipe 59. A connector 62 is fixedly connected between the end of the seventh air pipe 59 and the bottom sleeve 56. A second threaded pipe cap 63 is provided on the circumferential surface of the seventh air pipe 59. A second one-way air outlet valve 64 is provided inside the seventh air pipe 59 and is located inside the second threaded pipe cap 63. By setting up a negative pressure recovery structure, when the crescent-shaped container 22 takes a sample, the vinegar liquid attached to its surface drips naturally into the bottom sleeve 56 through the trough 65 at the bottom of the chassis 13, completing the initial recovery. At the same time, the piston cylinder 27 of the pneumatic structure generates negative pressure when it draws air through the one-way air inlet valve 31, the seventh air pipe 59 and the branch air inlet pipe 61. This negative pressure is transmitted to the connector 62 through the seventh air pipe 59, and then indirectly transmitted to the surface of the chassis 13 through the trough 65, actively adsorbing the residual vinegar liquid on the chassis 13 to the bottom sleeve 56. This solves the problem that manual cleaning is difficult to completely remove residual liquid, greatly improves the recovery coverage, avoids the waste of vinegar liquid, and by setting up a second one-way air outlet valve 64, when the negative pressure generated at the connector 62 causes some vinegar liquid to accumulate at the second threaded pipe cap 63, it can effectively prevent the liquid from flowing back to the seventh air pipe 59 and other components of the pneumatic structure.

[0024] Working principle: In the first step, during use, the operator can activate the electric push rod 23 through the control module, causing the output shaft of the electric push rod 23 to drive the circular electromagnet 24 to descend and magnetically attract the crescent-shaped container 22. At the same time, the arc electromagnet 21 in contact with the circular electromagnet 24 will be de-energized. Subsequently, the output shaft of the electric push rod 23 continues to extend and move down through the first through slot 25 and piston cylinder 27, immersing the crescent-shaped container 22 in vinegar. After a suitable volume is reached, the electric push rod 23 will retract, allowing the crescent-shaped container 22 to return to the chassis 13. Simultaneously, the arc electromagnet 21, which was previously de-energized, will be energized and attract the crescent-shaped container 22. The circular electromagnet 24 will be de-energized, and the electric push rod 23 will reset to its limit position, thus completing a single vinegar sampling. In the second step, when the output shaft of the electric push rod 23 descends, it drives the piston rod 28 to slide downwards inside the piston cylinder 27 via the connecting rod 55. The piston cylinder 27 draws in air through the one-way air inlet valve 31, the seventh air pipe 59, and the branch air inlet pipe 61. When the output shaft of the electric push rod 23 returns to its original position, the piston rod 28 compresses the internal air. The air is then transported to the air storage tank 32 for storage via the first one-way air outlet valve 29 and the third air pipe 38. After the crescent-shaped container 22 is sampled and reset, the first solenoid valve 33 is energized. Some of the gas in the air storage tank 32 is discharged into the rotary cylinder 37 via the first air pipe 35, the first solenoid valve 33, and the second air pipe 36. This drives the rotary cylinder 37 to rotate the rotating shaft 16 and the dial 17 one revolution, passing through the four equal slots. Wheel 19 drives the flat-bottomed shaft 18 and arc-shaped electromagnet 21 to rotate 90 degrees, causing the flat-bottomed shaft 18 to rotate as a whole. At the same time, the new crescent-shaped container 22 moves to the top of the first through slot 25 and the second through slot 57. During the rotation of the flat-bottomed shaft 18, the driven premixing structure is rotated synchronously, so that the driven premixing structure is precisely aligned with the current crescent-shaped container 22, thereby avoiding cross-interference. When the crescent-shaped container 22 needs to be removed, the fixed ring 47 is rotated through the notch of the housing 12, which drives the rotating rod 46 to rotate at the torsion spring bearing of the fixed plate 45, thereby driving the inner ring 48 and the auxiliary structure to rotate, so that the mixing main shaft 52 is disengaged from the crescent-shaped container 22. Then, the arc-shaped electromagnet 21 is de-energized, and the crescent-shaped container 22 can be removed. In the third step, after the crescent-shaped container 22 is sampled and reset to the chassis 13, the second solenoid valve 34 is energized. Part of the gas in the gas storage tank 32 is transported to the first connector 42 of the air slip ring 41 through the fourth gas pipe 39, the second solenoid valve 34, and the fifth gas pipe 44. Then, it is discharged into the inner ring 48 through the second connector 43 and the sixth gas pipe 54. When the gas is discharged through the gas outlet groove 53 of the inner ring 48, it impacts the small impeller 51 between the ring frame 49, drives the small impeller 51 to rotate and drives the mixing main shaft 52 to rotate. The mixing main shaft 52 realizes the stirring of vinegar inside the crescent-shaped container 22. In the fourth step, after sampling, the vinegar liquid attached to the crescent-shaped container 22 drips through the groove 65 of the base 13 into the bottom sleeve 56, completing the initial drip recovery. At the same time, when the piston cylinder 27 draws air through the one-way air inlet valve 31, the seventh air pipe 59 and the branch air inlet pipe 61, part of the negative pressure generated is transmitted to the connector 62 through the seventh air pipe 59. The connector 62 indirectly transmits the negative pressure to the surface of the base 13 through the groove 65, which helps to adsorb the residual vinegar liquid on the base 13 into the bottom sleeve 56. Due to the negative pressure generated by the connector 62, some vinegar liquid accumulates at the second threaded pipe cap 63. The second one-way air outlet valve 64 inside the seventh air pipe 59 can prevent the liquid from flowing back into the seventh air pipe 59. When cleaning is required, the second threaded pipe cap 63 and the first threaded pipe cap 58 can be opened to collect the vinegar liquid.
