[0002] Fermentation is the process of using microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions. Since different microorganisms have the ability to produce different metabolites, different microorganisms can be used to produce a variety of products needed by humans.

Once a wrong judgment is made, the fermented product is dumped out and found to be unqualified, and all work needs to be done again, wasting a lot of time and energy, which is very inconvenient. Therefore, during the fermentation process, it is necessary to detect the internal gas composition in order to understand whether the environment required for the fermentation process is suitable and to what extent the entire fermentation process has proceeded, so as to grasp the fermentation situation.

The other end of the pull rope 6 passes through the scale rod 4 and is connected to a driving mechanism. The driving mechanism is used to drive the pull rope 6 to move.

[0042] The sampling space 28 is also rotatably connected with a steering wheel 25, on which the pull rope 6 is hung, and the steering wheel 25 is used for the reversing of the pull rope 6. The piston 22 and the sampling space 28 are slidably connected, and the third spring 27 is arranged on the right side of the piston 22, the left end of the third spring 27 is connected to the piston 22, and the right end of the third spring 27 is connected to the sampling body 2.

[0043] An opening is provided at the lower end of the sampling space 28, through which the sampling space 28 is connected to the space in the fermentation tank 1. The opening is arranged in a vertical direction, and the aperture of the opening is suitable enough so that when the piston 22 moves to the right, the gas in the fermentation tank 1 can be sucked into the sampling space 28 through the opening.

[0044] In addition, the opening may be provided with two, one of which is provided with an air intake check valve, and the other is provided with an air outlet check valve, so when the piston 22 moves, the opening provided with the air intake check valve can perform the suction work.

[0045] The fixed block 10 is also fixedly connected to the detection box 3, and the detection box 3 is slidably connected to a probe rod 37 arranged in a vertical direction. The bottom end of the probe rod 37 is connected to a sensor assembly 39, and the sensor assembly 39 is provided with a sensor that can detect C0 2The sensor assembly 39 includes a plurality of detection sensors for concentration, internal temperature, humidity, impurity particles, bacteria, etc., so as to facilitate the detection of the corresponding components of the gas in the fermentation tank 1. The sensor assembly 39 specifically includes a carbon dioxide sensor, a temperature and humidity sensor, a particle sensor, and a biosensor.

[0046] The particle sensor is based on the principle of laser scattering and monitors the concentration of particles in the air in real time. The biosensor is an instrument that is sensitive to biological substances and converts their concentration into electrical signals for detection. It is an analytical tool or system composed of fixed biological sensitive materials as identification elements (including enzymes, antibodies, antigens, microorganisms, cells, tissues, nucleic acids and other biologically active substances), appropriate physical and chemical transducers (such as oxygen electrodes, photosensitive tubes, field effect tubes, piezoelectric crystals, etc.) and signal amplification devices.

[0047] Specifically, a channel is opened in the probe rod 37, and data lines of the carbon dioxide sensor, the temperature and humidity sensor, the particle sensor, and the biosensor are all arranged in the channel. After passing through the channel, the other ends of the data lines are connected to the display 11.

[0049] The probe rod 37 passes through the detection box 3 and the sealed space 26 from top to bottom in sequence and is then slidably disposed in the sampling space 28 ; a wedge-shaped sealing block 23 is connected to the sealed space 26 via a second spring 24 , and the wedge-shaped sealing block 23 is disposed between the sensor assembly 39 and the piston 22 .

[0050] The second spring 24 is arranged on the right side of the wedge-shaped sealing block 23, the left end of the second spring 24 is connected to the wedge-shaped sealing block 23, and the right end of the second spring 24 is connected to the sampling body 2. The second spring 24 is used for resetting the wedge-shaped sealing block 23. The upper surface of the wedge-shaped sealing block 23 is an inclined surface, so when the probe rod 37 moves downward, the probe rod 37 can contact the upper surface of the wedge-shaped sealing block 23, and can drive the wedge-shaped sealing block 23 to move rightward, and at this time the second spring 24 is compressed.

[0051] The wedge-shaped sealing block 23 is slidably connected to the sampling body 2, and the second spring 24 is always in a compressed state. Under the action of the second spring 24, the wedge-shaped sealing block 23 and the sealed space 26 are in close contact, so that under the action of the wedge-shaped sealing block 23, the sampling space 28 can form a relatively closed space to prevent the gas in the sampling space 28 from leaking out.

[0052] The sampling body 2 is provided with an upper exhaust pipe 13 and a lower exhaust pipe 14, which are connected to the activity space 15, and the lower exhaust pipe 14 is arranged on one side of the sampling body 2, and the upper exhaust pipe 13 is arranged above the sampling body 2. The upper exhaust pipe 13 and the lower exhaust pipe 14 can realize the extraction of air before detection to prevent the effect of detection from being affected, and when the gas is extracted, it is also convenient for the sampling body 2 and the fixing block 10 to fit each other, so that there is a better sealing effect in the fermentation tank 1 to prevent the occurrence of air leakage.

[0053] When the sampling body 2 moves upward in the fermentation tank 1, as the sampling body 2 contacts the activity space 15, the gas originally in the activity space 15 can be discharged into the fermentation tank 1 through the lower exhaust pipe 14, and as the probe rod 37 moves downward, the probe rod 37 can discharge the gas above the sampling body 2 into the fermentation tank 1 through the upper exhaust pipe 13.

[0054] The sampling body 2 is also provided with a slide groove, in which a fourth spring 29 and a positioning block 21 are slidably arranged, one end of the fourth spring 29 is connected to the positioning block 21, and the other end of the fourth spring 29 is connected to the sampling body 2; the fixing block 10 is provided with a positioning groove, and one end of the positioning block 21 passes through the slide groove and is slidably arranged in the positioning groove. When the sampling body 2 moves into the activity space 15, the contact surface between the positioning block 21 and the positioning groove is an inclined surface, and the positioning block 21 can be used for the relative fixing of the position of the sampling body 2.

[0055] A fifth spring 32 is sleeved on the probe rod 37, the lower end of the fifth spring 32 is connected to the detection box 3, and the upper end of the fifth spring 32 is connected to the probe rod 37. The fifth spring 32 is used for resetting the probe rod 37; a switch piece 34 is fixedly connected to the probe rod 37; and a movable piece 33 that cooperates with the switch piece 34 is rotatably connected in the detection box 3, and the movable piece 33 is connected to the detection box 3 through a sixth spring 35.

[0057] The contact surface between the switch sheet 34 and the movable sheet 33 is an inclined surface. When the probe rod 37 moves downward, the probe rod 37 can drive the movable sheet 33 to rotate through the switch sheet 34. When the movable sheet 33 jumps over the switch sheet 34, the right-angle grooves of the movable sheet 33 and the switch sheet 34 are engaged. At this time, the fifth spring 32 is compressed, which can prevent the probe rod 37 from moving upward under the action of the fifth spring 32.

[0058] The length of the probe rod 37 is appropriate enough. When the movable piece 33 and the switch piece 34 are engaged, the sensor assembly 39 is just moved into the sampling space 28. At this time, there is no need to continue pressing the probe rod 37 downward with force. The relative fixation of the position of the probe rod 37 can be achieved. At this time, the sensor assembly 39 is located in the sampling space 28, which allows the sensor assembly 39 to have enough time to detect the gas composition in the sampling space 28.

[0059] A switch rod 310 is slidably connected inside the detection box 3, and the upper end of the switch rod 310 passes through the detection box 3.

[0060] A guide rod 31 arranged in a vertical direction is fixedly connected in the detection box 3, and a groove is arranged in the switch rod 310. The guide rod 31 is slidably arranged in the groove. The guide rod 31 is used for relative limiting of the position of the switch rod 310, so that the switch rod 310 slides along the length direction of the guide rod 31.

[0061] The seventh spring 38 is arranged below the release sheet 36. The seventh spring 38 is sleeved on the guide rod 31 and the switch rod 310. The lower end of the seventh spring 38 is connected to the detection box 3, and the upper end of the seventh spring 38 is connected to the release sheet 36. The release sheet 36 is arranged in the horizontal direction. The contact surface between the release sheet 36 and the movable sheet 33 is an inclined surface. The release sheet 36 is arranged on one side of the switch sheet 34. Therefore, when the switch rod 310 drives the release sheet 36 to move downward, it can drive the movable sheet 33 to rotate, which is convenient for the movable sheet 33 to disengage and engage with the switch sheet 34.

[0062] The driving mechanism includes a fixed handle 53 fixedly connected to the scale rod 4 , the fixed handle 53 is rotatably connected to a movable handle 58 , the movable handle 58 is connected to the pull rope 6 , and the movable handle 58 is connected to the fixed handle 53 via an eighth spring 52 .

[0063] A cavity is provided in the scale rod 4, in which a fixed sealing block 12 located at the top and a movable sealing block 8 located at the bottom are arranged.

The lower pull rope is located below the movable sealing block 8, the upper end of the lower pull rope is connected to the movable sealing block 8, and the lower end of the lower pull rope is connected to the piston 22, so when the upper pull rope moves, the upper pull rope drives the lower pull rope to move upward through the movable sealing block 8, and the movable sealing block 8 is used for sealing the scale rod 4. The way of dividing the pull rope 6 into two ends can make it unnecessary to open extra holes in the movable sealing block 8, so as to have better sealing performance.

[0065] The movable handle 58 is rotatably connected to the fixed handle 53 through a pin shaft 51. The movable handle 58 is also provided with a movable groove 5. A small rotating shaft is movably connected in the movable groove 5. The small rotating shaft is connected to the pull rope 6. Under the action of the movable groove 5, the movable handle 58 can more conveniently drive the pull rope 6 to move, and the pull rope 6 will not tilt as much as possible when it rises.

When the movable handle 58 is pressed, the ratchet bar 54 can slide in the guide sleeve 57. Under the action of the inclined surface, the ratchet bar 54 drives the brake block 56 to move through the ratchet tooth, so that the ninth spring 55 is compressed. Under the action of the straight surface, the automatic locking work can be realized after the movable handle 58 is pressed.

[0069] By detecting the gas composition, the C0 2 Concentration, temperature, humidity, impurity particles, and bacteria can be used to determine whether the fermentation is normal at this time through the above differences, and at the same time, compared with the standard fermentation conditions to determine the fermentation situation.

At this time, the sixth spring 35 and the fifth spring 32 are compressed.

[0075] S5: As the probe rod 37 continues to move downward, the probe rod 37 drives the wedge-shaped sealing block 23 to move in the sealed space 26, thereby connecting the sealed space 26 and the sampling space 28.

[0076] In step S1, the method for the driving mechanism to drive the pull rope 6 to move includes pressing the movable handle 58, and the movable handle 58 drives the pull rope 6 to move upward. At this time, the eighth spring 52 is compressed, and at the same time the ratchet 54 moves in the guide sleeve 57, and the ratchet 54 drives the brake block 56 to move in the sliding hole 59. At this time, the ninth spring 55 is compressed to achieve the relative locking of the position of the movable handle 58.

[0077] In step S1, the method in which the scale rod 4 drives the sampling body 2 to move includes driving the sampling body 2 to move downward by the scale rod 4. Since the contact surface between the positioning block 21 and the positioning groove is an inclined surface, the positioning block 21 moves to the left under the action of the inclined surface. At this time, the fourth spring 29 is compressed, thereby releasing the relative fixed work between the sampling body 2 and the activity space 15.

[0078] In step S3, the method for moving the sampling body 2 into the active space 15 includes: the scale rod 4 drives the sampling body 2 to move upward, at which time the positioning block 21 is in contact with the active space 15, compressing the fourth spring 29, and as the sampling body 2 moves upward, when the positioning block 21 moves to one side of the positioning groove, under the action of the fourth spring 29, the positioning block 21 moves into the positioning groove, and since there is a certain friction between the scale rod 4 and the sealing assembly 9, under the action of the positioning block 21 and the friction, the relative fixing of the position of the sampling body 2 in the active space 15 is achieved.

[0079] It should be noted that the sampling body 2 can be moved downward by a suitable distance through the scale rod 4, and the piston 22 can be moved by the pull rope 6 to allow the gas to enter the sampling space 28. Under the action of the wedge-shaped sealing block 23, the gas in the sampling space 28 can be sealed to prevent gas leakage, thereby completing the sampling of the gas in the fermenter 1. The composition of the gas is displayed on the display 11, and the gas in the fermenter is analyzed to understand whether the environment required for the fermentation process is suitable and to what extent the entire fermentation process has proceeded, so as to grasp the fermentation situation.

[0080] In addition, the upper exhaust pipe 13 and the lower exhaust pipe 14 are provided. When the sampling body 2 is reset, the gas in the activity space 15 can be discharged into the fermentation tank 1 through the lower exhaust pipe 14. When the probe rod 37 moves downward, the gas above 28 of the sampling space can be discharged into the fermentation tank 1 through the upper exhaust pipe 13. This can realize the extraction of air before detection to prevent the detection effect from being affected. It can also facilitate the mutual fit between the sampling body 2 and the fixed block 10, so that there is a better sealing effect in the fermentation tank 1 to prevent the occurrence of air leakage.

[0081] In addition, when the probe rod 37 is pressed, the probe rod 37 drives the movable plate 33 to rotate through the switch plate 34, so that the movable plate 33 jumps over the switch plate 34 and engages with the switch plate 34, thereby realizing the relative fixation of the sensor assembly 39 after moving to the sampling space 28, which can prevent the probe rod 37 from resetting under the action of the spring during the detection process. The operator does not need to press the probe rod 37 all the time, and the corresponding gas composition analysis work can be performed through the sensor assembly 39. When the detection is completed, the switch rod 310 can be pressed, and the switch rod 310 drives the movable plate 33 to rotate, thereby releasing the restriction on the switch plate 34, so that the probe rod 37 can be reset, thereby completing the gas composition detection work.

[0082] In addition, by pressing the movable handle 58, the pull rope 6 can be driven to rise, and then the piston 22 can be driven to move, so that the gas enters the sampling space 28. When the movable handle 58 is pressed, the ratchet 54 slides in the guide sleeve 57, and the ratchet 54 and the brake block 56 cooperate with each other to achieve automatic locking after the movable handle 58 is pressed, thereby preventing the piston 22 from resetting under the action of the spring, facilitating the movement of the piston 22 to complete the gas sampling work. After the sampling is completed, the brake block 56 can be pulled outward to drive the brake block 56 and the ratchet 54 to disengage, and the ratchet 54 can slide freely in the guide sleeve 57, thereby completing the resetting of the piston 22, which is beneficial to the next detection work.

[0083] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
