Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation inoculation, and particularly to a microbial fermentation device for Chinese herbal medicines and its accessories. Background Art

[0002] A microbial fermentation device is a device used to cultivate and utilize microorganisms to carry out fermentation reactions under aerobic or anaerobic conditions, and is widely used in fields such as biopharmaceuticals, food fermentation, environmental engineering, agriculture, and bioenergy.

[0003] The fermentation of Chinese herbal medicines is to extract and purify Chinese medicinal materials with homology of medicine and food, and then carry out anaerobic fermentation with a preferred probiotic flora as the strain. After the Chinese herbal medicines are fermented by microorganisms, not only can the content of active substances and the medicinal efficacy of Chinese herbal medicines be increased, but also new active ingredients can be produced, reducing the toxic and side effects of Chinese herbal medicines. Adding the fermented Chinese herbal medicine feed additive to livestock and poultry feed can improve the production performance of livestock and poultry, improve the health status, and enhance the quality of livestock and poultry products. For example, Chinese Patent CN214193209U discloses a device for fermenting Chinese herbal medicines. The scheme includes an operating table, a fermentation cylinder, and a top cover. A fixed cylinder is provided on the upper surface of the top cover, a motor is provided inside the fixed cylinder, a stirring rod is provided at the rotating shaft end of the motor, a spiral ring is threadedly connected to the side surface of the top cover, and an N-shaped plate is fixedly connected to the upper surface of the top cover. In this scheme, an appropriate amount of Chinese herbal medicine is placed inside the fermentation cylinder, and then lactic acid bacteria liquid is inoculated into the fermentation cylinder. The motor is started to drive the stirring rod to rotate, so that the internal herbs are fully stirred, and the Chinese herbal medicines are fermented.

[0004] When inoculating microorganisms in a microbial fermentation device for Chinese herbal medicines, the flame inoculation method is often used. The flame inoculation method requires an alcohol flame to protect the entire inoculation process to ensure that no other microorganisms enter the fermentation cylinder during the inoculation process. However, the flame inoculation method is difficult to operate and highly tests the proficiency of the operator. For example, using a cotton ball dipped in alcohol to provide the flame, the size of the flame cannot be controlled, and it is easy to cause the initial flame to be too large and unable to continue. The operator has not completed the inoculation before the flame goes out. Secondly, the flame ring needs to pass through the T-shaped handle on the sealing cover. If the T-shaped handle is too long, it will cause obstruction. If the T-shaped handle is too short, attention needs to be paid to flame burns during inoculation, which is very inconvenient. Summary of the Invention

[0005] Based on this, in view of the problem of low inoculation efficiency and inconvenience during inoculation using the current flame inoculation method, it is necessary to provide a microbial fermentation device for Chinese herbal medicines and its accessories.

[0006] The above object is achieved through the following technical solutions: An accessory for a microbial fermentation device for Chinese herbal medicines, comprising: A cylinder body, two semi-circular clamps are hinged to the first end of the cylinder body, arc-shaped grooves are formed on both of the two semi-circular clamps, an end cover which slides axially along the cylinder body is arranged on the second end of the cylinder body, and push rods are hinged between the outer sides of the two semi-circular clamps and the end cover; A piston, the piston is axially slidably arranged in the cylinder body, the piston is in sliding seal with the cylinder body, fuel is filled in the cavity between the piston and the first end of the cylinder body, and the cavity is communicated with the arc-shaped grooves of the two semi-circular clamps; An adjusting assembly, the adjusting assembly can adjust the piston to adjust the flow rate of the fuel in the cavity entering the arc-shaped grooves, and the size of the flow rate is negatively correlated with the flame height in the arc-shaped grooves.

[0007] Further, the adjusting assembly includes an adjusting rod and an elastic member, the adjusting rod axially slides through the end cover, one end of the adjusting rod is in screw connection with the piston, the elastic member is sleeved on the outer periphery of the adjusting rod, one end of the elastic member is connected to the adjusting rod, and the other end of the elastic member abuts against the end cover, and the elastic member can make the adjusting rod have a tendency to drive the piston to move towards the first end of the cylinder body.

[0008] Further, a plurality of friction ridges arranged along the axial direction of the adjusting rod are arranged on the outer periphery of the end of the adjusting rod away from the piston.

[0009] Further, a sealing ring is arranged between the outer periphery of the piston and the inner periphery of the cylinder body, there are a plurality of sealing rings, and the plurality of sealing rings are distributed along the axial direction of the piston.

[0010] Further, the accessory of the microbial fermentation device for Chinese herbal medicines further includes a clamping assembly, and the clamping assembly is configured to fix the end cover on the second end of the cylinder body when the end cover moves axially along the cylinder body and approaches the cylinder body.

[0011] Further, the clamping assembly includes a first buckle and a second buckle that can be clamped with each other, there are at least two first buckles, the two first buckles are symmetrically arranged about the axis of the cylinder body on the second end of the cylinder body, there are at least two second buckles, and the two second buckles are symmetrically arranged about the axis of the end cover on the outer periphery of the end cover.

[0012] Further, a pressing plate is arranged on the second buckle.

[0013] Further, an arc-shaped sieve plate is arranged in the arc-shaped grooves of the two semi-circular clamps, and a plurality of micropores are formed on the arc-shaped sieve plate.

[0014] Furthermore, two flame-retardant hoses are arranged on the outer periphery of the first end of the cylinder body. One end of each of the two flame-retardant hoses is communicated with the cavity, and the other ends of the two flame-retardant hoses are respectively communicated with the arc-shaped grooves of the two semi-circular pliers, and the connection positions are located at the middle positions outside the semi-circular pliers.

[0015] The present invention also provides a microbial fermentation device for Chinese herbal medicines, including accessories of the microbial fermentation device for Chinese herbal medicines, and further including a fermentation cylinder. An inoculation port is arranged at the upper end of the fermentation cylinder, an inoculation cover is spirally connected to the inoculation port, and the two semi-circular pliers can surround the inoculation port.

[0016] The beneficial effects of the present invention are as follows: In the present invention, the two semi-circular pliers of the accessory pass through from the side of the inoculation cover of the fermentation cylinder, avoiding the influence of the length of the T-shaped handle, facilitating installation and use, solving the obstacle problem brought by the T-shaped handle in the traditional flame inoculation method, simplifying the operation process, and improving the inoculation efficiency. At the same time, a regulating component is provided to regulate the flow rate of the fuel entering the arc-shaped groove in the cavity, thereby controlling the flame height.

[0019] In the present invention, the arc-shaped sieve plate in the arc-shaped groove divides the groove, and its microporous design enables the fuel to slowly penetrate into the combustion material, prolonging the combustion time. The connection mode of the flame-retardant hoses enables the fuel to evenly enter the arc-shaped groove, ensuring uniform flame combustion and further improving the sterilization effect of the flame inoculation method.

[0025] In the present invention, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0026] The following refers to Figures 1 - 10 to describe an accessory of a microbial fermentation device for Chinese herbal medicines provided by the present invention.

[0027] An accessory of a microbial fermentation device for Chinese herbal medicines can ensure that the process of inoculating microorganisms is not contaminated, and includes a cylinder body 100. Two semi-circular clamps 200 are hinged on the first end 110 of the cylinder body 100. The two semi-circular clamps 200 can rotate around the hinged position. The two semi-circular clamps 200 can approach each other to form a complete circle, and the two semi-circular clamps 200 can also move away from each other, thereby facilitating the use of the two semi-circular clamps 200. Arc-shaped grooves 210 are provided on both of the two semi-circular clamps 200. The size of the arc-shaped grooves 210 is slightly smaller than the overall size of the semi-circular clamps 200. Combustible materials such as hemp ropes or alcohol cotton are placed in the arc-shaped grooves 210. After the operator places the two semi-circular clamps 200 at the designated position, the hemp ropes or alcohol cotton inside the arc-shaped grooves 210 are ignited to form a high-temperature disinfection and sterilization environment.

[0028] A end cover 240 capable of sliding axially along the cylinder body 100 is provided on the second end 120 of the cylinder body 100. Push rods 250 are hinged on the outer sides of the two semi-circular clamps 200. The other ends of the push rods 250 are hinged to the outer periphery of the end cover 240. When the end cover 240 moves axially along the cylinder body 100, it can drive the two semi-circular clamps 200 to rotate around the hinge position through the push rods 250. For example, when the end cover 240 moves axially along the cylinder body 100 in the direction close to the cylinder body 100, specifically as Figures 5 to 6 the state changes. The end cover 240 drives the two push rods 250 to push the two semi-circular clamps 200 to approach each other to form a complete circle. For example, when the end cover 240 moves axially along the cylinder body 100 in the direction away from the cylinder body 100, specifically as Figures 6 to 5 the state changes. The end cover 240 drives the two push rods 250 to pull the two semi-circular clamps 200 to move away from each other to separate the complete circle, which is convenient for the operator to place the two semi-circular clamps 200 at the position where disinfection and sterilization are required. After the operator places the two semi-circular clamps 200 at the designated position, the operator can push the end cover 240 to drive the two semi-circular clamps 200 to form a complete circle, and then ignite the fuel such as hemp rope or alcohol cotton in the arc-shaped grooves 210 of the two semi-circular clamps 200.

[0029] It can be understood that through the above arrangement of the two semi-circular clamps 200, it is avoided that the traditional flame ring passes through the T-shaped handle on the sealing cover, but passes through the side of the sealing cover, thereby preventing the T-shaped handle on the sealing cover from being too long and affecting the installation of the two semi-circular clamps 200.

[0030] It should be noted that, for the convenience of hinging the two semi-circular clamps 200 to the first end 110 of the cylinder body 100 and facilitating the disassembly of the two semi-circular clamps 200, a through hole 111 is opened on the first end 110 of the cylinder body 100. The through hole 111 is rectangular. A connecting disk 130 is installed inside the cylinder body 100. A connecting rod 140 is vertically and fixedly arranged at the center position of the connecting disk 130. The cross-section of the connecting rod 140 is rectangular, and the size of the connecting rod 140 is the same as the size of the through hole 111. After the connecting rod 140 passes through the through hole 111, one end face of the connecting disk 130 is attached to the inside of the first end 110 of the cylinder body 100. A wedge-shaped groove 150 is opened on the connecting rod 140. After a wedge-shaped block 160 is inserted into the wedge-shaped groove 150, the connecting disk 130 and the connecting rod 140 can be fixed to the first end 110 of the cylinder body 100. The part of the connecting rod 140 extending out of the first end 110 of the cylinder body 100 is hinged to the two semi-circular clamps 200, specifically by a screw hinge, and the two ends of the push rod 250 are also hinged to the outer sides of the two semi-circular clamps 200 and the outer periphery of the end cover 240 by screws.

[0031] Inside the cylinder body 100 of the present invention, a piston 260 is further provided. The piston 260 slides axially and is sealed inside the cylinder body 100. There is a cavity 180 between the piston 260 and the first end 110 of the cylinder body 100. The cavity 180 is filled with fuel, and the fuel can be clean energy such as alcohol or bio-ethanol. And the cavity 180 communicates with the arc-shaped grooves 210 of the two semi-circular clamps 200. The fuel in the cavity 180 can enter the arc-shaped grooves 210 of the two semi-circular clamps 200 to provide fuel for the combustion materials such as hemp ropes or alcohol cotton in the arc-shaped grooves 210. To ensure that the flame burning in the arc-shaped groove 210 can burn for a longer time and maintain the flame height unchanged during combustion, an adjustment component is provided inside the cylinder body 100. The adjustment component is used to adjust the flow rate of the fuel in the cavity 180 entering the arc-shaped groove 210. The flow rate is negatively correlated with the flame height burning in the arc-shaped groove 210. It can be understood that when the height of the flame gradually decreases with time, the adjustment component will increase the flow rate of the fuel in the cavity 180 entering the arc-shaped groove 210, so that the fuel in the arc-shaped groove 210 increases, and then the height of the flame increases, thereby avoiding the weakening of the disinfection and sterilization effect of the flame inoculation method caused by the height drop after long-term combustion. Of course, if the height of the flame is too high and affects the installation of the sealing cover, the flow rate of the fuel in the cavity 180 entering the arc-shaped groove 210 can be reduced through the adjustment component, so that the fuel in the arc-shaped groove 210 decreases, and on the premise of not affecting the disinfection and sterilization effect of the flame inoculation method, the height of the flame is appropriately reduced to avoid affecting the installation of the sealing cover.

[0032] It should be noted that, as Figure 3 shown, to prevent the leakage of fuels such as alcohol between the connecting disk 130 and the through hole 111, a waterproof gasket 170 is provided between the connecting disk 130 and the inside of the first end 110 of the cylinder body 100. The waterproof gasket 170 is used to improve the sealing performance between the connecting disk 130 and the inside of the first end 110 of the cylinder body 100, so as to prevent the leakage of fuels such as alcohol.

[0033] Specifically, as Figure 6 and Figure 7As shown, the adjustment assembly in the embodiment of the present invention includes an adjustment rod 270 and an elastic member 280. The adjustment rod 270 is axially slidably disposed within the cylinder 100 and passes through the center position of the end cap 240. One end of the adjustment rod 270 is helically connected to the piston 260. A helical groove is formed on the adjustment rod 270, and a circular groove is formed at a position of the piston 260 close to the end cap 240. The portion of the adjustment rod 270 having the helical groove is helically connected to the circular groove. When the adjustment rod 270 rotates relative to the piston 260, it can move axially along the piston 260 through the helical groove. In this embodiment, the elastic member 280 is a compression spring. The elastic member 280 is sleeved on the outer periphery of the adjustment rod 270. One end of the elastic member 280 is connected to the adjustment rod 270. A limiting ring 272 is coaxially and fixedly disposed on the outer periphery of the adjustment rod 270. One end of the elastic member 280 is connected to the limiting ring 272, and the other end of the elastic member 280 abuts against one end of the end cap 240 close to the piston 260. The elastic member 280 can push the adjustment rod 270 to drive the piston 260 to move in the direction close to the first end 110 of the cylinder 100 or make the adjustment rod 270 drive the piston 260 to have a tendency to move in the direction close to the first end 110 of the cylinder 100. Since the cavity 180 between the piston 260 and the cylinder 100 is filled with fuel, when the piston 260 moves, it can push the fuel in the cavity 180 into the arc-shaped groove 210. The operator can rotate the adjustment rod 270 to make the adjustment rod 270 rotate relative to the piston 260, so that the compression degree of the elastic member 280 on the outer periphery of the adjustment rod 270 changes. That is to say, the greater the compression degree of the elastic member 280, the greater the acting force of the elastic member 280 to push the adjustment rod 270 to move, the greater the acting force of the piston 260 to squeeze the cavity 180, and the greater the flow rate of the fuel in the cavity 180 entering the arc-shaped groove 210; if the compression degree of the elastic member 280 is smaller, the acting force of the elastic member 280 to push the adjustment rod 270 to move is smaller, the acting force of the piston 260 to squeeze the cavity 180 is smaller, and the flow rate of the fuel in the cavity 180 entering the arc-shaped groove 210 is smaller.

[0034] In a further embodiment, as Figure 1 and Figure 2As shown, on the outer periphery of the end of the adjusting rod 270 away from the piston 260, there are a plurality of friction ridges 271 arranged along the axial direction of the adjusting rod 270. The friction ridges 271 are used to increase the frictional force when an operator rotates the adjusting rod 270 by hand. By increasing the contact area with the operator's hand, the frictional force between the two is effectively enhanced. When the operator needs to rotate the adjusting rod 270, the friction ridges 271 can provide a firm grip. Even in special situations such as when the hand is wet or contaminated with oil, the risk of hand slipping can be significantly reduced, ensuring the safety and accuracy of the operation. In addition, the distribution density and height of the friction ridges 271 have been precisely calculated and repeatedly tested, which not only ensures sufficient frictional force but also avoids discomfort to the hand caused by the excessive height of the protrusions 340, achieving a balance between functionality and comfort and greatly optimizing the operating feel of the operator.

[0035] It should be noted that, as Figure 3 shown, in order to enable the piston 260 to be slidably and sealed within the cylinder 100, a sealing ring 261 is provided on the outer periphery of the piston 260. The number of the sealing rings 261 is multiple. In this embodiment, three are taken as an example. The three sealing rings 261 are distributed along the axial direction of the piston 260. The three sealing rings 261 provided between the piston 260 and the inner wall of the cylinder 100 can enable the piston 260 to be slidably sealed within the cylinder 100. It should also be noted that the frictional force of the three sealing rings 261 on the inner wall of the cylinder 100 is relatively large, so that the piston 260 remains stationary relative to the cylinder 100 when the adjusting rod 270 rotates, preventing the reduction of the adjustment accuracy caused by the rotation of the piston 260 driven by the rotation of the adjusting rod 270.

[0036] Of course, if the sealing ring 261 with a relatively large frictional force is not adopted, axially extending guiding ridges (not shown in the figure) can be provided on the inner wall of the cylinder 100. At the same time, a guiding groove extending along its axial direction (not shown in the figure) is opened on the outer periphery of the piston 260. The guiding groove and the guiding ridges are adapted to each other, and the two are slidably and sealed, which can also avoid the rotation of the piston 260 driven by the rotation of the adjusting rod 270, thereby ensuring the adjustment accuracy of the adjusting rod 270.

[0037] In a further embodiment, the accessory of the microbial fermentation device for Chinese herbal medicines further includes a clamping assembly 300. The clamping assembly 300 is configured to fix the end cover 240 on the second end 120 of the cylinder body 100 when the end cover 240 moves along the axial direction of the cylinder body 100 and approaches the cylinder body 100, so that the position of the end cover 240 is fixed. The two push rods 250 on the end cover 240 push the two semi-circular clamps 200 to form a complete circle. When the position of the end cover 240 is fixed, the complete circle formed by the two semi-circular clamps 200 is also fixed. And when the end cover 240 is fixed on the second end 120 of the cylinder body 100, one end of the elastic member 280 can push the piston 260 to move towards the first end 110 of the cylinder body 100 by pushing the adjusting rod 270. When the operator rotates the adjusting rod 270, the compression degree of the elastic member 280 can be adjusted, thereby changing the flow rate of the fuel in the cavity 180 into the two arc-shaped grooves 210.

[0038] Specifically, as Figure 4 and Figure 9 shown, the clamping assembly 300 includes a first buckle 310 and a second buckle 330 that can be mutually clamped. There are at least two first buckles 310. In this embodiment, two first buckles 310 are taken as an example. The two first buckles 310 are symmetrically arranged about the axis of the cylinder body 100 on the outer periphery of the second end 120 of the cylinder body 100. There are at least two second buckles 330. The number of the second buckles 330 is the same as that of the first buckles 310. In this embodiment, two second buckles 330 are taken as an example. The two second buckles 330 are symmetrically arranged about the axis of the end cover 240 on the outer periphery of the end cover 240. A slot 320 is formed on the first buckle 310, and a limiting slot is formed on the side wall of the slot 320. As Figure 9 shown, a protrusion 340 is provided on the second buckle 330, and an elastic card 341 is fixedly arranged on the protrusion 340. One end of the elastic card 341 is upturned, and the upturned end is named the unlocking end 342. When the second buckle 330 on the end cover 240 contacts the first buckle 310 on the cylinder body 100, the protrusion 340 on the second buckle 330 will enter the slot 320 of the first buckle 310, and the middle part of the elastic card 341 on the protrusion 340 will enter the limiting slot on the side wall of the slot 320. The unlocking end 342 of the elastic card 341 extends out of the slot 320. At this time, the first buckle 310 and the second buckle 330 are already clamped together, thereby fixedly connecting the end cover 240 to the second end 120 of the cylinder body 100.

[0039] It should be noted that when it is necessary to disassemble the end cover 240 and the cylinder body 100, the operator can press the unlocking end 342 of the elastic card 341. The middle part of the elastic card 341 will disengage from the limiting slot of the slot 320. The operator can pull the end cover 240 away from the cylinder body 100 to separate the end cover 240 from the cylinder body 100, which is convenient for disassembly and installation.

[0040] Specifically, as Figure 2 and Figure 4 shown, for the convenience of installing the first buckle 310 and the second buckle 330, connection holes are provided on both the first buckle 310 and the second buckle 330, and the first buckle 310 and the second buckle 330 are respectively fixedly installed on the outer periphery of the second end 120 of the cylinder 100 and the outer periphery of the end cover 240 through bolts 360.

[0041] In a further embodiment, as Figure 9 shown, a pressing plate 350 is fixedly arranged on the second buckle 330, and anti-slip ridges are arranged on the pressing plate 350. An operator can push the pressing plate 350 to facilitate the movement of the end cover 240 in the direction close to the cylinder 100.

[0042] Specifically, an arc-shaped sieve plate 220 is arranged in the arc-shaped groove 210 of the two semi-circular pliers 200 in the embodiment of the present invention. The arc-shaped sieve plate 220 divides the arc-shaped groove 210 into upper and lower parts. Combustible materials such as hemp ropes or alcohol cotton in the arc-shaped groove 210 are located on the arc-shaped sieve plate 220, and fuels such as alcohol are below the arc-shaped sieve plate 220. A plurality of micropores are provided on the arc-shaped sieve plate 220, and fuels such as alcohol can penetrate into the hemp ropes or alcohol cotton through the micropores, thereby increasing the burning time of the hemp ropes and alcohol cotton.

[0043] More specifically, the arc-shaped grooves 210 of the two semi-circular pliers 200 in this embodiment are connected to the cavity 180 in the cylinder 100 through two flame-retardant hoses (not shown in the figure). Two first joints 190 are arranged on the outer periphery of the first end 110 of the cylinder 100, and second joints 230 are arranged at the middle positions on the outer sides of the two semi-circular pliers 200. One end of the flame-retardant hose is connected to the first joint 190, and the other end of the flame-retardant hose is connected to the second joint 230, thereby connecting the cavity 180 and the arc-shaped grooves 210 of the two semi-circular pliers 200.

[0044] It should be noted that the apertures of the first joint 190 and the second joint 230 and the pipe diameter of the flame-retardant hose are very small, so that fuels such as alcohol in the cavity 180 can slowly enter the arc-shaped grooves 210 of the two semi-circular pliers 200, avoiding all fuels such as alcohol passing through the flame-retardant hose and entering the arc-shaped grooves 210 at one time. And arranging the second joint 230 at the middle position on the outer side of the semi-circular plier 200 can enable the fuels entering the arc-shaped grooves 210 from the cavity 180 to enter from the second joint 230 and be evenly distributed in the arc-shaped grooves 210, so that fuels such as alcohol are evenly absorbed by combustible materials such as hemp ropes or alcohol cotton, and the flame burns more evenly, thereby ensuring that the disinfection and sterilization effect of the flame inoculation method is maintained at a relatively high level.

[0045] The specific usage process of the accessories of a microbial fermentation device for Chinese herbal medicines provided by the present invention will be described in combination with the above embodiments: Initial state: Before use, the two semi-circular clamps 200 at the first end 110 of the cylinder body 100 are far away from each other. At this time, the first buckle 310 and the second buckle 330 on the end cover 240 are disengaged, and the end cover 240 is far away from the second end 120 of the cylinder body 100. The volume of the cavity 180 in the cylinder body 100 is relatively large, and fuels such as alcohol in the cavity 180 do not fill the entire cavity 180.

[0046] When inoculating microorganisms: The operator fills the arc-shaped grooves 210 of the two semi-circular clamps 200 with hemp ropes or alcohol cotton, and the hemp ropes or alcohol cotton are located on the arc-shaped sieve plate 220. After filling, the operator holds the cylinder body 100 with one hand and moves the cylinder body 100 close to the sealing cover. After both semi-circular clamps 200 are close to the sealing cover, they stop moving. The operator then pushes the pressing plate 350 on the end cover 240 with the other hand. By pushing the pressing plate 350, the end cover 240 is pushed towards the direction close to the cylinder body 100. During the movement of the end cover 240, the two semi-circular clamps 200 are pushed to rotate around the hinge position through the two push rods 250, so that the two semi-circular clamps 200 gradually close to form a complete circle, thereby surrounding the inoculation port 410. The second buckle 330 on the end cover 240 gradually approaches the first buckle 310 on the second end 120 of the cylinder body 100. When the middle part of the elastic card 341 on the protrusion 340 of the second buckle 330 enters the limiting groove on the side wall of the card slot 320 of the first buckle 310, the first buckle 310 and the second buckle 330 are buckled, and the end cover 240 is fixed on the second end 120 of the cylinder body 100 by the first buckle 310 and the second buckle 330.

[0047] Ignition: The operator ignites the combustion materials such as hemp ropes or alcohol cotton in the arc-shaped grooves 210 of the two semi-circular clamps 200, and then rotates the adjusting rod 270. When the adjusting rod 270 rotates around its own axis, it can rotate relative to the piston 260. Since the piston 260 and the adjusting rod 270 are connected by a screw, when the adjusting rod 270 rotates, the degree of compression of the elastic member 280 can be adjusted, that is, the force of the elastic member 280 pushing the piston 260 is adjusted. When the piston 260 moves towards the first end 110 of the cylinder body 100, it can squeeze the fuels such as alcohol in the cavity 180. The greater the degree of compression of the elastic member 280, the greater the flow rate of the alcohol and other fuels pushed by the piston 260 into the arc-shaped grooves 210 of the two semi-circular clamps 200, and vice versa, so as to maintain the flame height in the arc-shaped grooves 210 of the two semi-circular clamps 200 unchanged, thereby ensuring that the disinfection and sterilization effect of the flame inoculation method is maintained at a relatively high level.

[0048] The present invention also provides a microbial fermentation device for Chinese herbal medicines. The microbial fermentation device for Chinese herbal medicines includes the accessories of the above-mentioned microbial fermentation device for Chinese herbal medicines, and further includes a fermentation cylinder 400. As Figure 10 shown, an inoculation port 410 is provided at the upper end of the fermentation cylinder 400. An inoculation cover 420 is screwed onto the inoculation port 410. The inoculation cover 420 is used to seal the inoculation port 410. The inoculation cover 420 has the same structure as the above-mentioned sealing cover. A T-shaped handle is also provided on the inoculation cover 420. The T-shaped handle is used to install the inoculation cover 420 on the inoculation port 410 or remove the inoculation cover 420 from the inoculation port 410. When inoculation is required, the two semi-circular clamps 200 are placed at the position of the inoculation port 410 and the flame is ignited. Then, the inoculation cover 420 is opened to inoculate microorganisms into the inoculation port 410. After inoculation is completed, the inoculation cover 420 is covered. Finally, the two semi-circular clamps 200 are removed to complete the inoculation, preventing the microorganisms from being contaminated during the inoculation process.

[0049] It should be noted that the structure of the fermentation cylinder 400 in the present invention is the same as that of the fermentation cylinder 400 in the prior art, and the specific structure will not be described in detail.

[0050] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
