Description

Technical Field

[0001] The present application relates to the technical field of tea processing, and in particular to a tea fermentation device capable of evenly turning tea leaves. Background Art

[0002] Tea fermentation is a key link in the tea production process and has a decisive impact on the quality and taste of tea. The essence of tea fermentation is the enzymatic oxidation reaction of substances inside the tea leaves. After the tea cell walls are damaged, the oxidase enzymes (such as polyphenol oxidase, peroxidase) present in the cell walls promote a series of oxidation processes of catechins. During the fermentation process, the tea leaves need to be in full contact with oxygen to promote the transformation of internal chemical components, forming a unique aroma and flavor. Moreover, during the fermentation process, the tea leaf pile needs to be turned regularly to ensure that the tea leaves are heated evenly and avoid local over-fermentation.

[0003] Currently, the following problems still exist in the existing technologies:

[0004] 1. It is difficult for existing tea fermentation devices to evenly turn the tea leaves. In particular, the tea leaves are prone to sedimentation at the bottom of the fermentation device, resulting in the tea leaves at the bottom not being turned, thus causing uneven fermentation, leading to over-oxidation of some tea leaves (such as the generation of rancid taste) or insufficient oxidation (residual grassy smell), and the imbalance of the proportion of aroma components. Moreover, during the process of turning the tea leaves, some tea leaves are squeezed into lumps. If directly stirred, the rigidity is too strong, which may damage the tea leaves and affect the taste of the tea.

[0005] 2. It is difficult for existing tea fermentation devices to control the ventilation volume. Excessive ventilation will accelerate the oxygen supply, resulting in over-oxidation of tea polyphenols, forming too much theaflavin, making the color of the tea soup dull and the taste weak. Insufficient ventilation means insufficient oxygen supply during the fermentation process, resulting in incomplete oxidation of tea polyphenols and excessive residual catechins, and the tea soup has a strong bitter taste. In addition, a certain amount of dust is mixed during the ventilation process, and the dust particles will adhere to the surface of the tea leaves, resulting in dull color and reduced gloss of the dry tea, and spots or impurities appear on the tea leaves at the bottom, affecting the taste and commercial value of the tea. Summary of the Invention

[0006] In order to overcome the problem that existing tea fermentation equipment is difficult to evenly flip tea leaves, especially the problem that tea leaves are prone to sedimentation at the bottom of the fermentation equipment, resulting in the tea leaves at the bottom not being flipped, which causes uneven fermentation, leading to over-oxidation of some tea leaves (such as the production of rancid taste) or insufficient oxidation (residual grassy smell), imbalance in the proportion of aroma components, and during the flipping process of tea leaves, some tea leaves are squeezed into lumps. If directly stirred, the rigidity is too strong and may damage the tea leaves, affecting the taste of the tea. The tea fermentation equipment is difficult to control the size of ventilation. Excessive ventilation will accelerate the supply of oxygen, resulting in over-oxidation of tea polyphenols, forming too much theaflavin, making the color of the tea soup dull and the taste weak. Insufficient ventilation means insufficient oxygen supply during the fermentation process, resulting in incomplete oxidation of tea polyphenols and excessive residual catechins, and the tea soup has a strong bitter taste.

[0017] The technical solution provided by this application has at least the following technical effects or advantages:

[0018] 1. Due to the adoption of the stirring assembly, it effectively solves the problem that the existing tea fermentation equipment is difficult to evenly flip the tea. In particular, the tea is prone to sedimentation at the bottom of the fermentation equipment, resulting in the tea at the bottom not being turned over, which causes uneven fermentation, leading to over-oxidation (such as producing a rancid taste) or insufficient oxidation (residual grassy smell) of some tea, an imbalance in the proportion of aroma components, and during the flipping process of the tea, some tea is squeezed into blocks. If directly stirred, the rigidity is too strong, which may damage the tea and affect the taste of the tea. The present invention can evenly stir the fermented tea through the stirring assembly, can shake the tea sediment at the bottom, so that the tea at the bottom can be turned over, ensuring that all parts of the tea are fully in contact with oxygen, avoiding fermentation stagnation or over-oxidation caused by local hypoxia, and adopting flexible stirring during the stirring process to prevent damage to the agglomerated tea and protect the integrity of the tea, improving the taste of the tea.

[0019] 2. Due to the adoption of the ventilation component, it effectively solves the problem that it is difficult to control the ventilation size in existing tea fermentation equipment. Excessive ventilation will accelerate the oxygen supply, leading to excessive oxidation of tea polyphenols, forming too much theafulvin, making the color of the tea soup dull and the taste weak. Insufficient ventilation means insufficient oxygen supply during the fermentation process, resulting in incomplete oxidation of tea polyphenols and excessive residual catechins, making the tea soup bitter. In addition, during the ventilation process, a certain amount of dust is mixed in, and the dust particles will adhere to the surface of the tea leaves, resulting in dull color and reduced gloss of the dry tea, and spots or impurities on the leaf bottom, affecting the taste and commercial value of the tea. The ventilation component of the present invention can adjust the ventilation size according to the demand to ensure that the required ventilation volume meets the fermentation requirements, can prevent dust from entering the interior of the fermentation equipment, and can clean the dust attached to the filter screen to prevent blockage and affect ventilation.

Detailed implementation manners

[0034] For the difficulty in uniformly turning over the tea leaves, the present invention can uniformly stir the fermented tea leaves through the stirring assembly, shake the tea leaves settling at the bottom, so that the tea leaves at the bottom can be turned over, ensuring that all parts of the tea leaves are in full contact with oxygen; for the difficulty in controlling the ventilation size, the present invention can adjust the ventilation size according to requirements through the ventilation assembly to ensure that the required ventilation volume meets the fermentation requirements.

[0035] In order to better understand the above technical solution, the following will describe the above technical solution in detail in combination with the specification drawings and specific implementation manners.

[0036] Embodiment:

[0037] Please refer to Figure 1 and Figure 2As shown in the figure, a tea fermentation device capable of evenly turning over tea leaves includes a fermentation barrel 1. A top cover 2 is provided at the top end of the fermentation barrel 1. A first motor 3 is provided on the outer surface of the top cover 2. A floating disk 4 is slidably connected to the inner cavity of the fermentation barrel 1. A stirring assembly 5 is provided in the inner cavity of the fermentation barrel 1. A ventilation assembly 6 is provided on the outer surface of the fermentation barrel 1. Place the tea leaves inside the fermentation barrel 1, that is, above the floating disk 4. Drive the stirring assembly 5 to rotate through the operation of the first motor 3. The rotation of the stirring assembly 5 flips the tea leaves. While the stirring assembly 5 rotates, the floating disk 4 slides in the inner cavity of the fermentation barrel 1, causing the tea leaves on the floating disk 4, that is, the tea leaves at the bottom of the fermentation barrel 1, to shake, preventing the tea leaves at the bottom from settling and being insufficiently stirred. The ventilation assembly 6 is used for ventilation inside the fermentation barrel 1 to ensure the oxygen required for tea leaf fermentation.

[0038] Please refer to Figure 3 and Figure 5 As shown in the figure, the stirring assembly 5 includes a stirring frame 51. The output end of the first motor 3 and the top end of the stirring frame 51 are sleeved. The stirring frame 51 is rotatably connected to the top cover 2. A stirring mechanism 52 is provided on the outer surface of the stirring frame 51. A fixing plate 53 is fixedly installed at the top end of the stirring frame 51. Push rods 54 are fixedly installed on the lower surfaces of both ends of the fixing plate 53. A first connecting ring 55 is fixedly installed on the upper surface of the floating disk 4. A convex block 56 is fixedly installed on the upper surface of the first connecting ring 55. The bottom end of the push rod 54 fits with the upper surface of the first connecting ring 55. The two ends of the convex block 56 are flush with the first connecting ring 55, and the middle part of the convex block 56 protrudes. An anti-settling mechanism 57 is slidably connected to the inner cavity of the floating disk 4. A floating mechanism 58 is fixedly installed on the bottom wall of the fermentation barrel 1. A jacking mechanism 59 is provided on the outer surface of the floating mechanism 58. When turning over the tea leaves, the operation of the first motor 3 drives the stirring frame 51 to rotate. The rotation of the stirring frame 51 drives the stirring mechanism 52 to turn over the tea leaves. The rotation of the stirring frame 51 drives the fixing plate 53 to rotate. The rotation of the fixing plate 53 drives the push rod 54 to squeeze the convex block 56 on the first connecting ring 55. The convex block 56 is stressed to cause the floating disk 4 to slide down in the inner cavity of the fermentation barrel 1. The downward slide of the floating disk 4 drives the floating mechanism 58 to contract. The contraction of the floating mechanism 58 causes the jacking mechanism 59 to drive the anti-settling mechanism 57 to move upward. The anti-settling mechanism 57 pushes up the tea leaves at the bottom of the fermentation barrel 1. At the same time, combined with the up and down shaking of the floating disk 4, the tea leaves settled at the bottom of the fermentation barrel 1 can be fully stirred, improving the uniformity of fermentation oxygen mixing.

[0039] Please refer to Figure 3 and Figure 4As shown in the figure, the stirring mechanism 52 includes a rotating rod 521. At both ends of the rotating rod 521, first sliding rods 522 are fixedly installed. A first spring 523 is sleeved on the outer surface of the first sliding rods 522. A first sliding groove 524 is formed in the inner cavity of the stirring frame 51. A sliding plate 525 is fixedly connected to the outer surface of the rotating rod 521. A first limiting block 526 is fixedly installed on the outer surface of the stirring frame 51. A button 527 is arranged on the inner wall of the first limiting block 526. A stirring rod 528 is fixedly installed on the outer surface of the sliding plate 525. The first spring 523 is located between the rotating rod 521 and the inner wall of the stirring frame 51, ensuring the balance of the rotating rod 521 in the inner cavity of the stirring frame 51 and enabling the rotating rod 521 to have a certain floating space up and down in the inner cavity of the stirring frame 51. The first sliding rods 522 are slidably connected to the first sliding grooves 524. An alarm is arranged on the outer surface of the first limiting block 526. The button 527 is electrically connected to the alarm. Pressing the button 527 controls the alarm to sound an alarm. The rotating rod 521 is slidably connected to the inner cavity of the stirring frame 51. The sliding plate 525 is slidably connected to the first limiting block 526. There is a gap between the sliding plate 525 and the button 527. When the stirring frame 51 rotates during the flipping of the tea leaves, the stirring mechanism 52 is driven to rotate. At this time, the stirring rod 528 flips the tea leaves in the inner cavity of the fermentation barrel 1. Inevitably, there will be tea leaf blocks squeezed together during the flipping process. At this time, if the stirring rod 528 is too rigid, it is easy to damage the tea leaves. Therefore, when the stirring rod 528 passes through the tea leaf blocks, the rotating rod 521 slides in the inner cavity of the stirring frame 51. The sliding of the rotating rod 521 drives the first sliding rods 522 to slide in the inner cavity of the first sliding grooves 524, causing the sliding plate 525 to slide up and down in the direction of the stirring frame 51, so as to drive the stirring rod 528 to flip the tea leaves from the side when encountering the tea leaf blocks. The elastic force of the first spring 523 causes the rotating rod 521 to return to its original position after passing through the tea leaf blocks. After multiple flips, the tea leaf blocks are gradually loosened, thus avoiding damaging the tea leaves by directly flipping the tea leaf blocks. When the floating of the sliding plate 525 is too large, the sliding plate 525 slides in the inner cavity of the first limiting block 526, causing the sliding plate 525 to squeeze the button 527. At this time, the button 527 controls the alarm to sound an alarm, facilitating the staff to determine whether manual intervention is required according to the situation. For example, if the alarm sounds for a long time, it may indicate that there are relatively large hard blocks in the tea leaves that are difficult to flip, and the staff can then perform manual intervention.

[0040] Please refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the anti-settling mechanism 57 includes a fixed ring 571. A second sliding rod 572 is fixedly installed on the outer surface of the fixed ring 571. A gasket 573 is slidably connected to the outer surface of the second sliding rod 572. A floating ring 574 is arranged on the outer surface of the fixed ring 571. A connecting rod 575 is fixedly connected to the outer surface of the floating ring 574. A second connecting ring 576 is fixedly connected to the outer surface of the connecting rod 575. A second spring 577 is sleeved on the outer surface of the second sliding rod 572. The second spring 577 is located between the fixed ring 571 and the gasket 573 and is used to prevent the second spring 577 from rubbing against the inner wall of the floating ring 574. A floating groove 578 is formed in the middle part of the floating ring 574. The fixed ring 571 and the floating ring 574 are slidably connected. The gasket 573 and the floating ring 574 are slidably connected. The second sliding rod 572 and the floating groove 578 are slidably connected. The floating mechanism 58 includes a fixed frame 581. A fixed rod 582 is fixedly installed on the outer surface of the fixed frame 581. A third spring 583 is sleeved on the middle part of the fixed rod 582. Sliding seats 584 are arranged at both ends of the third spring 583. The sliding seats 584 and the fixed rod 582 are slidably connected. A connecting bar 585 is rotatably connected to the inner cavity of the sliding seat 584. One end of the connecting bar 585 away from the sliding seat 584 is rotatably connected to a floating plate 586. The lower surface of the fixed frame 581 is fixedly connected to the bottom wall of the fermentation barrel 1. The upper surface of the floating plate 586 is fixedly connected to the lower surface of the floating disk 4. The jacking mechanism 59 includes a support block 591. The support block 591 is fixedly connected to the fixed frame 581. A gear 592 is rotatably connected to the inner cavity of the support block 591. A first rack 593 is fixedly connected to the lower surface of the floating disk 4. A second limiting block 594 is fixedly installed on the outer surface of the fixed frame 581. A second rack 595 is slidably connected to the inner cavity of the second limiting block 594. A jacking rod 596 is fixedly installed at the top end of the second rack 595. The jacking rod 596 and the floating disk 4 are slidably connected. The top end of the jacking rod 596 is fixedly connected to the fixed ring 571. The gear 592 and the first rack 593 are meshed. The gear 592 and the second rack 595 are meshed. While the stirring frame 51 rotates to flip the tea leaves in the inner cavity of the fermentation barrel 1, it is difficult to take into account the flipping of the tea leaves at the bottom end of the fermentation barrel 1. At this time, the push rod 54 squeezes the convex block 56 to drive the floating disk 4 to generate extrusion on the floating plate 586. The pressing of the floating plate 586 drives the floating plate 586 to move towards the fixed frame 581. Thus, the connecting bar 585 rotates in the inner cavity of the sliding seat 584, causing the sliding seat 584 to squeeze the third spring 583 to realize the downward sliding of the floating disk 4. And the elastic force of the third spring 583 makes the sliding seat 584 slide on the fixed rod 582 to drive the floating plate 586 to return to its original position. At this time, the floating plate 586 drives the floating disk 4 to move upward. The tea leaves in the inner cavity of the fermentation barrel 1 generate a shaking effect during the up and down sliding of the floating disk 4, especially enabling the tea leaves settled at the bottom end to be fully dispersed. While the floating disk 4 slides downward, it drives the first rack 593 to move downward. The movement of the first rack 593 drives the gear 592 in the inner cavity of the support block 591 to rotate.The rotation of the gear 592 drives the second rack 595 to slide in the inner cavity of the second limit block 594. The sliding of the second rack 595 drives the push rod 596 to move. The movement of the push rod 596 drives the anti-settling mechanism 57 to move. Therefore, when the floating plate 4 moves downward, the anti-settling mechanism 57 can move upward, so that the tea leaves at the bottom end of the fermentation barrel 1 can be pushed away from the bottom, so as to cooperate with the shaking of the floating plate 4 to evenly turn the tea leaves and facilitate even contact with oxygen. When the anti-settling mechanism 57 pushes the tea leaves, it also has a flexible force to avoid damage to the tea leaves. The push rod 596 drives the fixing ring 571 to move upward. When encountering a tea leaf block, the second connecting ring 576 will float to avoid direct squeezing with the tea leaf block. At this time, the second connecting ring 5 76 drives the connecting rod 575 to move, and the connecting rod 575 drives the floating ring 574 to slide on the second slide rod 572, that is, the second slide rod 572 slides in the inner cavity of the floating groove 578 and squeezes the second spring 577. The elastic force of the second spring 577 can restore the floating ring 574 and the fixed ring 571 to their original positions, that is, the fixed ring 571 and the floating ring 574 are flexibly connected, so that there is a certain floating space when the floating ring 574 drives the second connecting ring 576 to push the bottom tea leaves to turn over. With the flexible stirring of the stirring mechanism 52 and the flexible lifting of the tea leaves by the bottom anti-settling mechanism 57, the tea leaves can be evenly turned over while avoiding damage to the tea leaves, thereby protecting the integrity of the tea leaves and improving the taste of the tea leaves.

[0041] See also Figure 2 and Figure 10 As shown, the ventilation assembly 6 includes a connecting pipe 61, and second slide grooves 62 are provided at the upper and lower ends of the connecting pipe 61. An adjusting mechanism 63 is inserted into the outer surface of the connecting pipe 61. The inner cavity of the second slide groove 62 is slidably connected with a dustproof mechanism 64. A collecting mechanism 65 is fixedly installed on the outer surface of the fermentation barrel 1. The collecting mechanism 65 is located directly below the second slide groove 62. The connecting pipe 61 is embedded in the outer surface of the fermentation barrel 1. The connecting pipe 61 is connected to the interior of the fermentation barrel 1. The dustproof mechanism 64 can slide in the inner cavity of the second slide groove 62 for dust removal. The adjusting mechanism 63 is used to adjust the ventilation volume, the dustproof mechanism 64 is used to prevent dust, and the collecting mechanism 65 is used to collect dust blocked by the dustproof mechanism 64 and clean the dustproof mechanism 64 to prevent dust generated during ventilation from clogging the dustproof mechanism 64.

[0042] See also Figure 10 and Figure 11As shown, the adjusting mechanism 63 includes a ventilation pipe 631. A regulating blade 632 is rotatably connected to the inner cavity of the ventilation pipe 631. A connection disk 633 is arranged at the middle part of the ventilation pipe 631. Two ends of the regulating blade 632 are respectively rotatably connected to the ventilation pipe 631 and the connection disk 633. An adjusting ring 634 is rotatably connected to the outer surface of the ventilation pipe 631. A driving rod 635 is fixedly installed on the outer surface of the adjusting ring 634. An adjusting plate 636 is fixedly installed at one end of the regulating blade 632 away from the connection disk 633. An adjusting groove 637 is formed on the outer surface of the adjusting plate 636. The driving rod 635 is slidably connected to the adjusting groove 637. A plug rod 638 is fixedly installed on the outer surface of the ventilation pipe 631. The plug rod 638 is inserted into the connecting pipe 61. When it is necessary to adjust the ventilation volume inside the fermentation barrel 1, by rotating the position of the adjusting ring 634 on the ventilation pipe 631, the rotation of the adjusting ring 634 drives the driving rod 635 to move. The movement of the driving rod 635 drives the driving rod 635 to slide in the adjusting groove 637 on the adjusting plate 636, that is, the angle of the adjusting plate 636 deflects. The deflection of the adjusting plate 636 drives the regulating blade 632 to rotate between the ventilation pipe 631 and the connection disk 633, so that the gap between the regulating blades 632 changes, and the ventilation volume between the regulating blades 632 changes. The deflection angle between the regulating blades 632 can be adjusted according to requirements. There is a large frictional force between the adjusting ring 634 and the ventilation pipe 631. The adjusting ring 634 slides on the outer surface of the ventilation pipe 631 due to external force fluctuations, ensuring the stability of the adjusting ring 634 on the ventilation pipe 631.

[0043] Please refer to Figure 10 , Figure 12 and Figure 13As shown in the figure, the dust-proof mechanism 64 includes a filter screen 641. The filter screen 641 is slidably connected to the inner cavity of the second chute 62, and the gap of the second chute 62 is greater than the thickness of the filter screen 641. The filter screen 641 is closely attached to the inner cavity of the second chute 62 on the side close to the fermentation barrel 1. A resilient rod 642 is fixedly installed at the bottom end of the filter screen 641. A fourth spring 643 is sleeved on the outer surface of the resilient rod 642. A limiting ring 644 is fixedly installed on the outer surface of the resilient rod 642. The fourth spring 643 is located between the limiting ring 644 and the lower surface of the connecting pipe 61, so that the filter screen 641 maintains balance in the inner cavity of the connecting pipe 61 and can block the whole connecting pipe 61 for dust prevention. The resilient rod 642 is slidably connected to the connecting pipe 61, and the bottom end of the resilient rod 642 is rounded. The dust collection mechanism 65 includes a dust collection box 651. A threaded rod 652 is rotatably connected to the outer surface wall of the dust collection box 651. A moving block 653 is sleeved on the outer surface of the threaded rod 652. The moving block 653 is threadedly connected to the threaded rod 652. The moving block 653 is slidably connected to the outer surface of the dust collection box 651. A second motor 654 is arranged on the outer surface of the dust collection box 651. The second motor 654 is a stepping motor for facilitating the control of the reciprocating movement of the moving block 653 on the threaded rod 652. The output end of the second motor 654 is sleeved on the threaded rod 652. Dust guiding rods 655 are evenly arranged on the inner wall of the dust collection box 651. A scraping plate 656 is slidably connected to the upper surface of the dust guiding rods 655. One end of the scraping plate 656 is fixedly connected to a pressure plate 657. The end of the scraping plate 656 far from the pressure plate 657 is fixedly connected to the moving block 653. The scraping plate 656 is slidably connected to the dust collection box 651. The dust collection box 651 is located directly below the second chute 62. The dust collection box 651 is fixedly connected to the outer surface of the fermentation barrel 1. The upper surface of the dust guiding rods 655 is convex in the middle, which is convenient for scraping the dust on the dust guiding rods 655 onto the dust collection box 651 by the scraping plate 656. The upper surface of the pressure plate 657 is uneven. When the scraping plate 656 moves, the pressure plate 657 passes through the bottom end of the resilient rod 642. By the operation of the second motor 654, the threaded rod 652 rotates, and the moving block 653 slides on the outer surface of the dust collection box 651. The movement of the moving block 653 drives the scraping plate 656 to slide on the dust guiding rods 655. At the same time, the movement of the scraping plate 656 drives the pressure plate 657 to move. The movement of the pressure plate 657 drives the pressure plate 657 to pass through the bottom end of the resilient rod 642. At this time, the pressure plate 657 generates a continuous extrusion force on the resilient rod 642, so that the resilient rod 642 slides in the inner cavity of the connecting pipe 61. At the same time, the elastic force of the fourth spring 643 generates an extrusion force on the limiting ring 644. Thus, under the action of the uneven upper surface of the pressure plate 657, the filter screen 641 generates a continuous shaking effect, so that the dust attached to the outer surface of the filter screen 641 falls on the dust guiding rods 655, avoiding dust blockage and affecting the internal ventilation of the fermentation barrel 1. The dust guiding rods 655 make the dust fall to the bottom of the dust collection box 651 under the scraping of the scraping plate 656, collecting the dust dropped from the filter screen 641 and preventing dust from entering the internal of the fermentation equipment.It can clean the dust attached to the filter screen 641 to prevent blockage and affect ventilation.

[0044] In summary, the tea leaves are placed inside the fermentation barrel 1, that is, above the floating plate 4. The operation of the first motor 3 drives the stirring assembly 5 to rotate. The rotation of the stirring assembly 5 flips the tea leaves. While the stirring assembly 5 rotates, the floating plate 4 slides inside the inner cavity of the fermentation barrel 1, causing the tea leaves on the floating plate 4, that is, the tea leaves at the bottom of the fermentation barrel 1, to shake, preventing the tea leaves at the bottom from settling and being insufficiently stirred. The ventilation assembly 6 is used for ventilation inside the fermentation barrel 1 to ensure the oxygen required for tea leaf fermentation. When flipping the tea leaves, the operation of the first motor 3 drives the stirring frame 51 to rotate, and the rotation of the stirring frame 51 drives the stirring mechanism 52 to flip the tea leaves. The rotation of the stirring frame 51 causes the push rod 54 to squeeze the convex block 56 on the first connecting ring 55. The convex block 56 is stressed, causing the floating plate 4 to slide downward inside the inner cavity of the fermentation barrel 1. The downward slide of the floating plate 4 drives the floating mechanism 58 to contract. The contraction of the floating mechanism 58 causes the jacking mechanism 59 to drive the anti-settling mechanism 57 to move upward. The anti-settling mechanism 57 pushes up the tea leaves at the bottom of the fermentation barrel 1. At the same time, in cooperation with the up-and-down shaking of the floating plate 4, the tea leaves settled at the bottom of the fermentation barrel 1 can be fully stirred, improving the uniformity of fermentation oxygen mixing. The connecting pipe 61 communicates with the inside of the fermentation barrel 1. The dust-proof mechanism 64 can slide inside the second chute 62 for dust removal. The adjusting mechanism 63 is used to adjust the ventilation volume. The dust-proof mechanism 64 is used for dust prevention. The collection mechanism 65 is used to collect the dust blocked by the dust-proof mechanism 64 and clean the dust-proof mechanism 64 to avoid blockage of the dust-proof mechanism 64 by the dust generated during ventilation.
