Description

Technical Field

[0001] This invention relates to the field of air supply system technology, specifically to an automatic air supply system for a blower. Background Technology

[0002] As is well known, a blower is a commonly used fluid transport machine. It uses a rotating impeller to draw in air or other gases from one area, uses centrifugal force to pressurize or compress the gas, and then transports the gas to another area. A blower mainly consists of six parts: a motor, an air filter, a blower body, an air chamber, a base (which also serves as an oil tank), and an oil drip nozzle. This allows the blower to provide the required airflow and pressure to the transport pipeline, thereby realizing the transport of materials.

[0003] For example, the patent titled "An Automatic Adjustment Air Supply System for a Roots Blower," published on September 14, 2021, with announcement number CN112856666B, addresses the problem of providing an automatic adjustment air supply system for a Roots blower. This system can reduce the difference in air volume between various air supply ducts through self-adjustment, making them relatively balanced. It includes a Roots blower, whose exhaust port is connected to a main air supply duct. Multiple air supply ducts are connected in parallel along the air supply direction. The exhaust port of each air supply duct is connected to an outer cylinder of a base. An adjustable inner cylinder, capable of vertical movement, is fitted inside the outer cylinder. The side wall of the adjustable inner cylinder has a strip-shaped outlet along its height direction. An elastic component is installed between the adjustable inner cylinder and the outer cylinder of the base.

[0004] The shortcoming of the existing technology is that the blower's air outlet is connected to the air supply pipe, and the blower delivers gas to each air supply branch pipe through the air supply pipe. Due to the certain flow resistance at the connection between the blower's air outlet and the air supply pipe, the internal pressure of the blower increases, causing gas backflow, which in turn affects the blower's air delivery effect. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic air supply adjustment system for blowers, thereby solving the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic blower air supply system, comprising a blower body and an impeller body, wherein the impeller body is rotatably disposed inside the blower body, and an adjustment unit is also included. The adjustment unit includes an air inlet pipe, the air inlet end of the blower body is connected to the air inlet pipe, and an adjustment plate is rotatably connected to the top and bottom ends of the air inlet pipe through a positioning shaft. The distance between the two adjustment plates gradually decreases from the end away from the blower body to the end closer to the blower body.

[0007] As described above, a motor body is connected to the blower body, a drive shaft is connected to the output end of the motor body, an impeller body is connected to the drive shaft, and the impeller body is located inside the blower body.

[0008] The aforementioned adjustment unit further includes a first elastic element, and the two adjustment plates are connected to each other via a first elastic element at the end near the blower body and the top inner wall of the air inlet pipe.

[0009] As described above, a filter unit is provided at the end of the air intake pipe, the filter unit includes a first filter screen, the end of the air intake pipe is provided with a first filter screen, and the inside of the air intake pipe is provided with a second filter screen.

[0010] The aforementioned filter unit further includes a third filter screen. A slot is provided at the top of the air intake pipe, and the third filter screen is slidably disposed in the slot, with the third filter screen located in the gap between the first filter screen and the second filter screen.

[0011] As mentioned above, the top and bottom ends of the third filter screen are respectively connected to the air intake pipe by two parallel threaded rods.

[0012] As mentioned above, the mesh positions and sizes of the first, second, and third filters are all the same, enabling them to filter the delivered gas.

[0013] As described above, the impeller body is composed of a driven circular plate, a driven circular ring, and an impeller plate. The driven circular plate and the driven circular ring are rotatably disposed inside the blower body. One end of the driven circular plate is connected to the drive shaft, and the driven circular ring is near the end of the air inlet pipe. Multiple impeller plates are evenly arranged between the driven circular plate and the driven circular ring along their circumferential direction.

[0014] As described above, the blower body is provided with an air outlet pipe, and multiple exhaust pipes are connected to the air outlet pipe along its axial direction.

[0015] As mentioned above, each of the exhaust pipes is provided with a balancing unit, which is used to balance the gas discharged from each exhaust pipe.

[0016] The beneficial effects of this invention are as follows: when the blower body is conveying gas, the gas flows from the end with the larger gap between the two regulating plates to the end with the smaller gap between the two regulating plates, which increases the gas flow rate and reduces the pressure inside the blower body. The reduction in pressure can reduce the impact force on the impeller body. Even if some gas flows back, the inclined setting of the regulating plates can block the backflowing gas to a certain extent, thereby improving the blower's air delivery effect.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 14 The present invention will now be described in further detail.

[0035] One embodiment of the present invention relates to an automatic blower air supply system, including a blower body 1 and an impeller body 2. The impeller body 2 is rotatably disposed inside the blower body 1. The system also includes an adjustment unit, which includes an air inlet pipe 3. The air inlet end of the blower body 1 is connected to the air inlet pipe 3. An adjustment plate 5 is rotatably connected to the top and bottom ends of the air inlet pipe 3 through a positioning shaft 4. The distance between the two adjustment plates 5 gradually decreases from the end away from the blower body 1 to the end closer to the blower body 1.

[0036] Specifically, the blower is a device for gas transportation. The blower body 1 has an annular chamber inside. The inlet pipe 3 is a square tube. A positioning shaft 4 is located at both the top and bottom of the inlet pipe 3. An adjusting plate 5 is rotatably mounted on each of the two positioning shafts 4. The middle of the adjusting plate 5 is rotatably mounted on the positioning shaft 4. A motor body 6 is connected to the blower body 1. The output end of the motor body 6 is connected to a drive shaft 7. An impeller body 2 is connected to the drive shaft 7. The impeller body 2 is located inside the blower body 1, that is, it is rotatably installed within the chamber. The impeller body 2 is composed of a driven circular plate 8, a driven circular ring 9, and an impeller plate 10. The driven circular plate 8 and the driven circular ring 9 are rotatably mounted inside the blower body 1. The driven circular plate 8 is rotatably installed in the chamber. One end of the driven circular plate 8 is connected to the drive shaft 7. The driven circular ring 9 is close to the end of the inlet pipe 3. Multiple impeller plates 10 are evenly arranged circumferentially between the driven circular plate 8 and the driven circular ring 9. The driven circular plate 8 and the impeller plates 10 are driven to rotate by the motor body 6 and the drive shaft 7. When the motor body 6 rotates and drives the impeller body 2 to rotate, the gas between the impeller plates 10 in the impeller body 2 also rotates. Under the action of centrifugal force, the gas is thrown out, and the gas velocity increases, so that the gas converts kinetic energy into static pressure energy in the flow. Then, with the increase of fluid pressure, the static pressure energy is converted into velocity energy and discharged through the exhaust port. A certain negative pressure is formed in the middle of the impeller plates 10. Because the inlet is negative pressure, the outside gas... The gas is immediately replenished under atmospheric pressure, and continuously discharged and replenished under the continuous rotation of the impeller body 2, thereby achieving the purpose of continuous air supply. The air supply principle of the blower is common knowledge in this field and will not be elaborated. The adjustment unit also includes a first elastic element 45. The two adjustment plates 5 are connected to the inner wall of the top of the air inlet pipe 3 at the end near the blower body 1 by a first elastic element 45. The first elastic element 45 (which is a component that can extend and return to its original position, preferably a spring) provides a certain elastic force to the adjustment plates 5, so that the two adjustment plates 5 are in an inclined state. That is, under the elastic force of the two first elastic elements 45, the distance between the two adjustment plates 5 changes from the end away from the blower body 1 to the end near the blower body 1. The opening between the two adjusting plates 5 gradually decreases from the air inlet end to the impeller body 2 end. When the motor body 6 transports gas through the impeller body 2, the gas enters the blower body 1 from between the two adjusting plates 5 in the air inlet pipe 3. Since the gas has a certain initial velocity when entering the impeller body 2, it will continuously impact the impeller body 2 during long-term use, which can easily cause damage to the impeller body 2. In this embodiment, the gas is transported through the blower body 1 and the impeller body 2, and the gas flows from the end with the larger gap between the two adjusting plates 5 to the end with the smaller gap between the two adjusting plates 5. That is, the gas intake path gradually narrows, thereby increasing the gas flow rate.Furthermore, as the pressure (static pressure) decreases (as can be seen from the continuity equation and Bernoulli's equation for low-speed fluids: when the pipe contracts, the gas velocity increases and the pressure (static pressure) decreases), the first elastic element 45 possesses a certain elastic force, allowing the adjusting plate 5 to swing slightly. Even with the adjusting plate 5 swinging back and forth, the gas intake path gradually contracts, enabling the gas to enter the blower body 1 along the outer surface of the adjusting plate 5. This allows the adjusting plate 5 to stably deliver the gas. Simultaneously, the decrease in pressure reduces the impact force of the gas on the impeller body 2, improving the service life of the impeller body 2. Even if some gas backflow occurs within the internal cavity of the blower body 1 due to the increased gas velocity, in this embodiment, the inclined adjusting plate 5 has a certain blocking effect on the backflowing gas, thereby improving the blower's air delivery effect.

[0037] The shortcoming of the existing technology is that the blower's air outlet is connected to the air supply pipe, and the blower delivers gas to each air supply branch pipe through the air supply pipe. Due to the certain flow resistance at the connection between the blower's air outlet and the air supply pipe, the internal pressure of the blower increases, causing gas backflow, which in turn affects the blower's air delivery effect.

[0038] The beneficial effects of this embodiment are as follows: when the blower body 1 is conveying gas, the gas flows from the end with the larger gap between the two regulating plates 5 to the end with the smaller gap between the two regulating plates 5, which increases the gas flow rate and reduces the pressure inside the blower body 1. The reduction in pressure can reduce the impact force on the impeller body 2. Even if some gas flows back, due to the inclined setting of the regulating plates 5, the regulating plates 5 can block the backflowing gas to a certain extent, thereby improving the blower's air delivery effect.

[0039] In another embodiment of the present invention, a filter unit is provided at the end of the air intake pipe 3. The filter unit includes a first filter screen 11, and a second filter screen 12 is provided inside the air intake pipe 3. The filter unit also includes a third filter screen 13. A slot 14 is provided at the top of the air intake pipe 3, and the third filter screen 13 is slidably disposed in the slot 14, and the third filter screen 13 is located in the gap between the first filter screen 11 and the second filter screen 12. The top and bottom ends of the third filter screen 13 are respectively connected by two parallel threaded rods. 15 is connected to the intake pipe 3, that is, the top and bottom ends of the intake pipe 3 are evenly provided with multiple threaded holes. The third filter screen 13 is rotatably provided with a threaded rod 15. The position of the third filter screen 13 in the gap between the first filter screen 11 and the second filter screen 12 can be adjusted through the threaded connection between the threaded rod 15 and the threaded hole, that is, the third filter screen 13 is driven to move radially. The mesh positions and sizes of the first filter screen 11, the second filter screen 12 and the third filter screen 13 are all the same, so that the first filter screen 11, the second filter screen 12 and the third filter screen 13 can filter the delivered gas.

[0040] Specifically, when the blower body 1 and impeller body 2 generate negative pressure to adsorb gas, the negative pressure generated by the rotation of impeller body 2 is relatively large, resulting in a large negative pressure at the end of the air inlet pipe 3 during gas adsorption. This may lead to the adsorption of large but lightweight impurities (such as plastic bags, toilet paper, etc.). These impurities entering the chamber of the blower body 1 may damage or become entangled in the impeller body 2. In this embodiment, a filter unit is installed at the air inlet end of the air inlet pipe 3 to prevent impurities from being drawn into the air inlet pipe 3. When the blower body 1 and impeller body 2 transport gas, the gas flows from the... Filter 11, filter 13, and filter 12 enter the intake pipe 3. These filters filtration methods treat the air entering the intake pipe 3, preventing impurities from entering the blower body 1. Filter 11 and filter 12 are of the same specification, with identical mesh positions and sizes. When adjusting the mesh size of filters 11, 13, and 12, the operator uses a tool to tighten the threaded rod 15. 5. The third filter screen 13 slides within the gap between the first filter screen 11 and the second filter screen 12, causing a certain misalignment between the mesh openings on the third filter screen 13 and the mesh openings on the first filter screen 11 and the second filter screen 12. This changes the size of the mesh openings on the first filter screen 11, the second filter screen 12, and the third filter screen 13. By adjusting the position of the third filter screen 13 within the gap between the first filter screen 11 and the second filter screen 12, the size of the mesh openings on the first filter screen 11, the second filter screen 12, and the third filter screen 13 can be adjusted. As those skilled in the art will know, when the third filter screen 13... When the mesh openings on the blower body 1 completely overlap with those on the first filter screen 11 (or the second filter screen 12), the mesh openings on the first filter screen 11, the second filter screen 12, and the third filter screen 13 are at their largest. In addition, when some gas flows back into the internal cavity of the blower body 1 due to the increase in gas flow velocity, the backflowing gas can generate a reverse airflow on the first filter screen 11, the second filter screen 12, and the third filter screen 13, thereby cleaning the first filter screen 11, the second filter screen 12, and the third filter screen 13 and improving the stability of the first filter screen 11, the second filter screen 12, and the third filter screen 13 in filtering the gas.

[0041] In another embodiment of the present invention, the connection portion between the two adjusting plates 5 and their corresponding positioning shafts 4 is an arc-shaped block 16. That is, each of the two adjusting plates 5 is provided with an arc-shaped block 16 in the middle. The arc-shaped block 16 and the adjusting plate 5 are fixedly connected, and the arc-shaped block 16 and its corresponding positioning shaft 4 are rotatably arranged. The arc-shaped block 16 and the adjusting plate 5 can rotate around the positioning shaft 4. The two arc-shaped blocks 16 are respectively rotatably arranged on their corresponding positioning shafts 4. A plurality of driven teeth 17 are evenly arranged on the arc-shaped block 16 along its circumferential direction. The impeller body 2. The impeller body 2 is located inside the cavity of the blower body 1. It can slide along the axial direction of the drive shaft 7 within the cavity of the blower body 1, meaning that when the impeller body 2 is impacted by gas during gas transport, it can slide along the axial direction of the drive shaft 7. The impeller body 2 can also be rotated by the rotating shaft 7, which is divided into a first shaft 18 and a second shaft 19. The first shaft 18 is connected to the driven circular plate 8, and the second shaft 19 is connected to the output end of the motor body 6. The second shaft 19 can drive the first shaft 18 to rotate. The two shafts are interlocked (the interlocking part is a non-rotating body), the first shaft 18 and the second shaft 19 are connected by a second elastic element 20. The impeller body 2 can also rotate inside the cavity of the blower body 1. A connecting ring groove 21 is opened on the side wall of the driven ring 9 on the impeller body 2 near the adjusting plate 5. A through groove 22 is opened at the top and bottom of the air inlet pipe 3. An active rod 23 is slidably installed in each of the two through grooves 22. An arc-shaped rod 24 is connected to one end of each of the two active rods 23 inside the blower body 1. 4 are installed in the connecting ring groove 21 by rotational engagement. Multiple active teeth 25 are evenly arranged on both active rods 23. The active teeth 25 on the two active rods 23 are respectively engaged with the driven teeth 17 on the corresponding arc surface block 16. The opposing surfaces of the two adjusting plates 5 are both inclined surfaces, that is, the inclined surfaces of the two adjusting plates 5 gradually tilt from the end away from the blower body 1 to the end closer to the blower body 1, so that the distance between the two adjusting plates 5 gradually decreases from the end away from the blower body 1 to the end closer to the blower body 1.

[0042] Specifically, since the impeller body 2 is constantly subjected to gas impact during gas absorption and transport due to the lack of a buffer structure, in this embodiment, the drive shaft 7 is configured as a telescopic structure, and the first shaft 18 and the second shaft 19 of the drive shaft 7 are connected by a second elastic element 20. The second elastic element 20 (a retractable and repositionable element, preferably a spring) provides a certain elastic force to the first shaft 18 and the second shaft 19, allowing them to slide relative to each other. When the impeller body 2 rotates to generate negative pressure to absorb gas, the impact force generated by the gas acts on the impeller body 2. When the rotational speed of the impeller body 2 increases... The impact force generated by the gas will push the impeller body 2 to slide along the axial direction of the first shaft 18 and the second shaft 19, causing the impeller body 2 to slide towards the end closer to the motor body 6. Because the connecting ring groove 21 and the arc-shaped rod 24 on the driven ring 9 of the impeller body 2 are rotatably connected, the rotation of the impeller body 2 will not affect the arc-shaped rod 24 or the driving rod 23. When the impeller body 2 slides towards the end closer to the motor body 6, the driven ring 9 on the impeller body 2 is axially connected (i.e., along the axial direction of the transmission shaft 7) between the connecting ring groove 21 and the arc-shaped rod 24, causing the driven ring 9 to drive the driving rod 23 to slide towards the end closer to the motor body 6 (e.g., via the connecting ring groove 21 and the arc-shaped rod 24). Figure 14As shown, both the connecting annular groove 21 and the arc-shaped rod 24 have T-shaped cross-sections. The connecting annular groove 21 is an annular groove with a T-shaped cross-section, and the arc-shaped rod 24 is an arc-shaped rod with a T-shaped cross-section. The two arc-shaped rods 24 can also be replaced by a T-shaped ring with a T-shaped cross-section (connected to the two driving rods 23 via a T-shaped ring). Because the driving teeth 25 on the driving rod 23 and the driven teeth 17 on the arc-shaped block 16 are meshed with each other, the driving rod 23 drives the adjusting plate 5 via the arc-shaped block 16 to position the shaft. Rotating around the center, the distance between the two adjusting plates 5 near the blower body 1 decreases, thereby reducing the pressure inside the blower body 1. This reduces the impact force of the airflow inside the blower body 1 on the impeller body 2. Simultaneously, the driven circular plate 8 on the impeller body 2 pushes the first shaft 18 to slide towards the second shaft 19. The first shaft 18 compresses the second elastic element 20, putting it in a compressed state. Because the impact force of the airflow inside the blower body 1 on the impeller body 2 is reduced... Under the rebound action of the second elastic element 20, the second elastic element 20 pushes the first shaft 18 to slide away from the motor body 6. The first shaft 18 pushes the impeller body 2 to slide away from the motor body 6. The driven ring 9 on the impeller body 2 drives the driving rod 23 to slide away from the motor body 6 through the arc surface rod 24. Since the driving teeth 25 on the driving rod 23 and the driven teeth 17 on the arc surface block 16 are meshed with each other, the driving rod 23 drives the adjusting plate 5 to rotate around the positioning shaft 4 through the arc surface block 16, which increases the distance between the two adjusting plates 5 near the blower body 1, and reduces the flow rate of the gas entering the blower body 1. Through the sliding of the impeller body 2 in the axial direction of the first shaft 18 and the second shaft 19, the second elastic element 20 can perform a certain buffering operation on the impact force of the gas acting on the impeller body 2. At the same time, the swinging adjusting plate 5 can adjust the flow rate entering the blower body 1 and prevent damage to the impeller body 2.

[0043] In another embodiment of the present invention, an inverted U-shaped frame 26 is provided at the top of the third filter screen 13. The U-shaped frame 26 consists of two vertical rods 27 and a horizontal rod 28. The two vertical rods 27 are connected to the top of the third filter screen 13. The bottom end of the horizontal rod 28 and the bottom end of the third filter screen 13 are each provided with an inclined surface. A lifting plate 29 is connected to the end of each of the two active rods 23 near the blower body 1. The top of each of the two lifting plates 29 is provided with an inclined surface, and the inclined surfaces on the two lifting plates 29 are respectively wedge-shapedly fitted with their corresponding inclined surfaces.

[0044] Specifically, when the impeller body 2 slides towards the end closer to the motor body 6, the driven ring 9 on the impeller body 2 drives the arc-shaped rod 24 and the driving rod 23 to slide towards the end closer to the motor body 6 through the connecting ring groove 21. Since the end of the driving rod 23 is connected to the lifting plate 29, and the inclined surface on the lifting plate 29 is wedge-shapedly fitted with its corresponding inclined surface, and both the inclined surface and the inclined surface on the lifting plate 29 are inclined downward from the end away from the driving rod 23 to the end closer to the driving rod 23, the lifting plate 29 can push the U-shaped frame 26 and the third filter screen 13 to slide towards the top of the air intake pipe 3, thereby adjusting the third filter screen 1. The position of the third filter 13 within the gap between the first filter screen 11 and the second filter screen 12 causes a certain misalignment between the mesh openings on the third filter screen 13 and the mesh openings on the first filter screen 11 and the second filter screen 12. This reduces the size of the mesh openings on the first filter screen 11, the second filter screen 12, and the third filter screen 13, thereby reducing the flow of gas into the intake pipe 3 from the first filter screen 11, the second filter screen 12, and the third filter screen 13. This reduces the pressure inside the blower body 1, thus reducing the impact force of the airflow inside the blower body 1 on the impeller body 2. At the same time, the driven circular plate 8 on the impeller body 2 pushes the first shaft 18 towards the second shaft 19. As the first shaft 18 slides, it compresses the second elastic element 20, putting the second elastic element 20 into a compressed state. Due to the reduced impact force of the airflow on the impeller body 2 within the blower body 1, the second elastic element 20 rebounds, pushing the first shaft 18 to slide away from the motor body 6. The first shaft 18 then pushes the impeller body 2 to slide away from the motor body 6. The driven ring 9 on the impeller body 2 drives the driving rod 23 to slide away from the motor body 6 via the arc-shaped rod 24. The driving rod 23 drives the lifting plate 29 to slide away from the motor body 6. Under the weight of the third filter screen 13... Under the action of the filter, the third filter 13 slides towards the bottom of the air inlet pipe 3, making the mesh size of the first filter 11, the second filter 12 and the third filter 13 larger, thus reducing the flow velocity of the gas entering the blower body 1. Through the reciprocating sliding of the impeller body 2 in the axial direction of the first shaft 18 and the second shaft 19, the second elastic element 20 can buffer the impact force of the gas on the impeller body 2. At the same time, by adjusting the size of the mesh size of the first filter 11, the second filter 12 and the third filter 13, the flow velocity entering the blower body 1 can be adjusted to prevent damage to the impeller body 2.

[0045] In another embodiment of the present invention, the blower body 1 is provided with an exhaust pipe 30, and a plurality of exhaust pipes 31 are connected to the exhaust pipe 30 along its axial direction; each of the exhaust pipes 31 is provided with a balancing unit, and each balancing unit is used to balance the gas discharged from each exhaust pipe 31. The balancing unit includes a balancing frame 32, one end of the balancing frame 32 is connected to the exhaust pipe 30 through the exhaust pipe 31, and the other end of the balancing frame 32 is connected to a gas delivery pipe 33. A separator 34 is provided inside the balancing frame 32. The separator 34 is made of rubber material, so that the separator 34 has a certain elastic deformation capability. A pressure relief rod 35 is provided on the balancing frame 32. The end of the pressure relief rod 35 is slidably sealed to the middle of the separator 34. One end of the pressure relief rod 35 is a first round rod 36, and the first round rod 36 is connected to the balancing frame 32. Next, the other end of the pressure relief rod 35 is a second round rod 37, which is slidably sealed to the middle of the separator membrane 34. The radius of the first round rod 36 is smaller than that of the second round rod 37. The first round rod 36 and the second round rod 37 are connected by a frustum 38. A third elastic element 39 is sleeved on the outer wall of the pressure relief rod 35. One end of the third elastic element 39 is connected to the balance frame 32, and the other end of the third elastic element 39 is connected to the separator membrane 34. The balance frame 32 has an air intake channel 40 at one end of the exhaust pipe 31. An auxiliary shaft 41 is provided between the two side walls of the balance frame 32. A balance rod 42 is rotatably mounted on the auxiliary shaft 41. One end of the balance rod 42 is connected to a sealing cover 43, which is used to seal the end of the air intake channel 40. The other end of the balance rod 42 is connected to the separator membrane 34 through an elastic band 44.

[0046] Specifically, when the gas inside the blower body 1 is delivered to the outlet pipe 30 through the impeller body 2, the gas in the outlet pipe 30 moves along its axial direction and is delivered to each exhaust pipe 31. Because the exhaust pipes 31 are positioned differently on the outlet pipe 30, the distance between each exhaust pipe 31 and the blower body 1 is different. The gas delivery volume in the exhaust pipe 31 farther from the blower body 1 is smaller than that in the exhaust pipe 31 closer to the blower body 1, resulting in uneven gas delivery. In this embodiment, a balancing unit is installed on the exhaust pipe 31 to balance the gas delivery in each exhaust pipe 31. The gas in the blower body 1 is delivered to the outlet pipe 30 through the impeller body 2. The gas in the outlet pipe 30 is then delivered to each exhaust pipe 31 and to the intake channel 40. The gas in the intake channel 40 pushes the sealing cover 43. Under the impact of the gas, the sealing cover 43 drives the balance bar 42 to rotate around the auxiliary shaft 41, thus releasing the seal of the intake channel 40. This allows the gas in the intake channel 40 to enter the balance frame 32. The gas then exits from the balance frame 32 into the air delivery pipe 33 and is delivered to different chambers that require air intake. During the rotation around the auxiliary shaft 41, the balance bar 42 stretches the elastic band 44 to a certain extent, and the separator 34 slides towards the first round rod 36 under the pushing action of the gas inside the balance frame 32. Since the separator 34 is made of rubber, it has a certain elastic deformation capability. As the separator 34 moves towards the first round rod 36, it squeezes the third elastic element 39 (the second elastic element 20 is a component capable of extension and retraction, preferably a spring), causing the third elastic element 39 to be in a compressed state. When the gas flow rate in the exhaust pipe 31 decreases, the third elastic element 39 rebounds. Under the action of the third elastic element 39, the separator 34 is pushed to slide towards one end of the second round rod 37, reducing the tension of the elastic band 44 on the sealing cover 43. This allows the sealing cover 43 to slowly enter the air intake channel 40 without sealing it, thus achieving a certain balance in gas delivery. When the gas flow rate in the exhaust pipe 31 increases (especially in the exhaust pipe 31 near the blower body 1), the impact of the gas on the sealing cover 43 causes the sealing cover 43 to open the air intake channel 40 more fully, and the impact of the gas on the separator 34 is greater, causing the separator 34 to slide from the second round rod 37 onto the first round rod 36 (e.g., Figure 13As shown), the separator 34 is disengaged from the second round rod 37, allowing gas storage to occur within the space between the separator 34 and the first round rod 36 in the balance frame 32. Those skilled in the art will know that a connecting pipe is installed within the space between the first round rod 36 and the separator 34 in the balance frame 32. This connecting pipe connects to other exhaust pipes 31 or outlet pipes 30, enabling the gas within the space between the first round rod 36 and the separator 34 in the balance frame 32 to be transported to other exhaust pipes 31 or outlet pipes 30. At this time, the elastic band 44 reaches its maximum stretch, and the elastic band 44 drives... The balance bar 42 rotates around the auxiliary shaft 41, causing the balance bar 42 to drive the sealing cover 43 to seal the end of the air intake channel 40. At the same time, the compression of the third elastic element 39 reaches its maximum. Under the rebound action of the third elastic element 39, the third elastic element 39 pushes the separator 34 to slide onto the second round rod 37, so that the separator 34 and the second round rod 37 re-slide and seal. Through the reciprocating motion of the separator 34 and the reciprocating swing of the sealing cover 43 driven by the balance bar 42, the gas delivery volume in the balance frame 32 reaches a balanced delivery state, so that the gas delivery volume in each exhaust pipe 31 is relatively uniform.
