Two adjustment plates 5 are equidistantly abutted against the inner side of the buffer plate 8. A first baffle is abutted against the upper inner side of the two adjustment plates 5. The first baffle is fixedly connected to the inner wall of the adjustment box 2. A second baffle is abutted against the lower inner side of the two adjustment plates 5. The second baffle is fixedly connected to the partition 4. A slide table 6 is fixedly connected to the middle of the outer sides of the two adjustment plates 5. A screw rod 7 is sleeved inside each of the two slide tables 6, and the two screw rods 7 are arranged in a mirror image. The two screw rods 7 are fixedly connected to each other. One end of a screw rod 7 is movably sleeved with a limit sleeve. One side of the limit sleeve is fixedly connected to the inner wall of the adjustment box 2. With such a setting, pull the pull plate until the pull plate drives the fixed rod to no longer pass through the limit hole 17. At the same time, the pull plate drives the first spring 15 to stretch. Push the toothed plate 12 through the handle 13. The toothed plate 12 drives the gear 11 to rotate. The gear 11 drives the worm gear 9 to rotate through the worm 10. The worm gear 9 drives the two screw rods 7 to rotate through the second transmission rod. Because the two screw rods 7 are arranged in a mirror image, the two screw rods 7 drive the two adjustment plates 5 to approach each other through the slide tables 6. The two adjustment plates 5 close the buffer holes on the buffer plate 8 to realize the adjustment of the air intake. At the same time, the toothed plate 12 drives the pointer 14 to move. Through the pointer 14 and the scale plate 18, the user can determine the adjustment degree of the air intake. With such a setting, it is convenient to precisely adjust the air intake and convenient for the user to observe the adjustment degree of the air intake.

[0028] As Figures 1 - 7 shown, a first fixing hole is provided on one side of the adjustment box 2. One end of a screw rod 7 is fixedly connected with a second transmission rod. The second transmission rod passes through the first fixing hole. One end of the second transmission rod is fixedly connected with a worm gear 9. A worm 10 is tooth-connected to one side of the worm gear 9. A gear 11 is fixedly connected above the worm 10. A limit box is abutted against the lower side of the gear 11. The limit box is fixedly connected to the adjustment box 2, and the second transmission rod is movably sleeved with the limit box. With such a setting, the worm gear 9 can drive the gear 11 through the worm 10.

[0029] As Figures 1 - 7As shown, one side of the gear 11 is engaged with a toothed plate 12, and the toothed plate 12 is movably sleeved in the limit box. One side above the toothed plate 12 is fixedly connected with a handle 13, and the other side above the toothed plate 12 is fixedly connected with a first spring 15. The upper part of the first spring 15 is fixedly connected with a pull plate, and the lower part of the pull plate is fixedly connected with a limit rod. A second fixing hole is opened above the toothed plate 12, and the limit rod passes through the second fixing hole. A number of limit holes 17 are equidistantly opened below the limit box, and the limit rod passes through the adjacent limit hole 17. A pointer 14 is fixedly connected above the toothed plate 12, and a scale plate 18 is fixedly connected to one side of the limit box. Through such a setting, the adjustment degree of the adjustment device can be determined according to the corresponding position of the pointer 14 on the scale plate 18.

[0030] As Figures 1 - 4 , Figures 8 - 9 shown, a third fixing hole is opened below the adjustment box 2, and an electric push rod 20 passes through the third fixing hole. A connecting plate is fixedly connected to the outside of the electric push rod 20, and the inner side of the connecting plate is fixedly connected to the adjustment box 2. The transmission end of the electric push rod 20 is fixedly connected with a sealing plate 19, and one side of the sealing plate 19 abuts against the inner wall of the adjustment box 2, and the other side of the sealing plate 19 abuts against the partition plate 4. Through such a setting, the electric push rod 20 pushes the sealing plate 19 to move. When the sealing plate 19 closes the buffer plate 8, the air flow entering the adjustment box 2 can only flow through the space where the mounting plate 23 is located from below the partition plate 4.

[0031] As Figures 1 - 4 , Figures 8 - 9As shown in the figure, a mounting plate 23 is fixedly connected to the lower part inside the adjustment box 2, a partition plate 4 is fixedly connected above the mounting plate 23, a connection hole 24 is formed in the middle of one side of the mounting plate 23, and fourth fixing holes are formed on both sides of one side of the mounting plate 23. A third transmission rod passes through each of the two fourth fixing holes. A movable plate 21 is fixedly connected to one side of the two third transmission rods, a transmission plate is fixedly connected to one end of the two third transmission rods, a second spring 22 is fixedly connected to the inner side of each of the two transmission plates, and one end of each of the two second springs 22 is fixedly connected to the mounting plate 23. Through such a setting, when the electric push rod 20 is started, the electric push rod 20 drives the sealing plate 19 to move upward until the sealing plate 19 closes the buffer hole on the buffer plate 8. At this time, after the intake air enters the adjustment box 2, the intake air passes through the space between the movable plate 21 and the mounting plate 23 and is discharged from the connection hole 24 on the mounting plate 23. When the intake air increases rapidly and the pressure becomes larger, the intake air flow pushes the movable plate 21 to move. The movable plate 21 drives the second spring 22 to stretch through the third transmission rod and the transmission plate. At the same time, the movable plate 21 and the mounting plate 23 approach each other, and the space between the movable plate 21 and the mounting plate 23 becomes smaller, and the intake air discharged through the mounting plate 23 becomes less, realizing the control of the intake air volume. When the intake air entering the adjustment box 2 becomes less and the pressure becomes smaller, the second spring 22 drives the movable plate 21 to reset through the third transmission rod and the transmission plate. The space between the movable plate 21 and the mounting plate 23 becomes larger, and the intake air discharged through the mounting plate 23 becomes more, realizing the control of the intake air volume. Through such a setting, it is convenient to switch the adjustment mode of the pipeline and realize automatic adjustment.

[0032] As Figures 1 - 2 shown, a first connecting pipe 1 is fixedly connected to the outside of the first mounting hole on one side of the adjustment box 2, a second mounting hole is formed on one side of the adjustment box 2, a second connecting pipe 3 is fixedly connected to the outside of the second mounting hole on one side of the adjustment box 2, and a control panel 25 is fixedly connected to the outside of the adjustment box 2. Through such a setting, the electric push rod 20 can be controlled through the control panel 25.

[0033] It should be noted that during use, the first connecting pipe 1 is fixedly connected to the intake pipe, the second connecting pipe 3 is fixedly connected to the exhaust pipe, the control panel 25 is connected to an external power supply. After the intake air enters the adjustment box 2 through the first connecting pipe 1, the air flow is blocked by the sealing plate 19 and flows through the buffer hole on the buffer plate 8, and then the air flow is discharged through the second connecting pipe 3.

[0034] When manual adjustment of the intake air volume is required, pull the pull plate until the fixed rod driven by the pull plate no longer passes through the limit hole 17. At the same time, the first spring 15 driven by the pull plate is stretched. Push the toothed plate 12 through the handle 13. The toothed plate 12 drives the gear 11 to rotate. The gear 11 drives the worm gear 9 to rotate through the worm 10. The worm gear 9 drives two screw rods 7 to rotate through the second transmission rod. Since the two screw rods 7 are arranged mirror-symmetrically, the two screw rods 7 drive two adjusting plates 5 to approach each other through the sliding table 6. The two adjusting plates 5 close the buffer holes on the buffer plate 8 to achieve the adjustment of the intake air volume. At the same time, the toothed plate 12 drives the pointer 14 to move. Through the pointer 14 and the scale plate 18, the user can determine the degree of adjustment of the intake air volume. After the adjustment is completed, release the pull plate, and the first spring 15 contracts to drive the fixed rod to pass through the adjacent limit hole 17 for fixation.

[0035] When automatic adjustment of the intake air volume is required, start the electric push rod 20 through the control panel 25. The electric push rod 20 drives the sealing plate 19 to move upward until the sealing plate 19 closes the buffer holes on the buffer plate 8. At this time, after the intake air enters the adjustment box 2, the intake air passes through the space between the movable plate 21 and the mounting plate 23 and is discharged from the connection hole 24 on the mounting plate 23. When the intake air increases rapidly and the pressure becomes larger, the intake air flow pushes the movable plate 21 to move. The movable plate 21 drives the second spring 22 to stretch through the third transmission rod and the transmission plate. At the same time, the movable plate 21 and the mounting plate 23 approach each other, and the space between the movable plate 21 and the mounting plate 23 becomes smaller, and the intake air discharged through the mounting plate 23 becomes less to achieve the control of the intake air volume. When the intake air entering the adjustment box 2 becomes less and the pressure becomes smaller, the second spring 22 drives the movable plate 21 to reset through the third transmission rod and the transmission plate. The space between the movable plate 21 and the mounting plate 23 becomes larger, and the intake air discharged through the mounting plate 23 becomes more to achieve the control of the intake air volume.

[0036] The present utility model provides an adjustable intake air volume pipeline, which solves the problems that manual adjustment is often used when adjusting the intake air volume. When performing manual adjustment, the existing adjustment device is not convenient for precise adjustment and it is not convenient for the user to observe the adjustment degree. When the intake air volume changes frequently, the adjustable intake air volume pipeline also needs to automatically adjust according to the intake air volume to maintain the intake air volume within a balanced range. The existing adjustable intake air volume pipeline is not convenient to switch between manual adjustment and automatic adjustment, and is relatively practical.

[0037] The above shows and describes the basic principles, main features and advantages of the present utility model.
