When the adjusting bolt 5 moves up and down, the airflow adjustment seat 7 is driven to rotate along its hinge, that is, the adjusting bolt 5 can change the position of the airflow adjustment seat 7 in the fixing seat 8. An alignment protrusion 13 is provided in the fixing seat 8, and an alignment notch 12 matched with the alignment protrusion 13 is formed on the airflow adjustment seat 7. An active airflow inlet 2 is opened on the fixing seat 8, and the airflow adjustment seat 7 is used In order to control the conduction between the active airflow inlet 2 and the inside of the fixed seat 8, when the airflow adjustment seat 7 is controlled to rotate by the adjusting bolt 5, the alignment notch 12 formed on the airflow adjustment seat 7 is adapted to the alignment protrusion 13 provided on the fixed seat 8, but when the alignment notch 12 and the alignment protrusion 13 are completely in contact, the inside of the fixed seat 8 and the active airflow inlet 2 are closed to each other, blocking the mutual flow of air between the active airflow inlet 2 and the fixed seat 8. Similarly, the alignment notch 12 and the alignment protrusion 13 can be controlled to be away from each other or partially in contact with each other to achieve the conduction or partial conduction of the input of the active airflow inlet 2, to control the input amount of the airflow in the active airflow inlet 2, to achieve effective control of the airflow input and output in the fixed seat 8, to achieve effective control of the airflow pressure in the airflow flow channel 15, and to achieve the airflow pressure value output by the airflow flow channel 15 to be a controllable value to ensure the uniformity of the tobacco selection.

[0022] Advantageously, a section of thread is formed on the adjusting bolt 5, and the top of the adjusting bolt 5 is threadedly connected to the housing 1 through a thread formed on one end thereof. The adjusting bolt 5 can be threadedly connected to the housing through a thread formed on one end thereof. At the same time, the upper and lower height positions of one end thereof in the fixing seat 8 can be changed through threaded cooperation, thereby driving the airflow adjusting seat 7 to rotate. A return spring 14 is provided between the housing 1 and the fixing seat 8, and one end of the return spring 14 abuts against the housing 1, and the other end abuts against the top of the fixing seat 8. The return spring 14 can be On the one hand, it can realize the resetting and force support of the adjusting bolt 5, and on the other hand, it can avoid the threaded rotation between the adjusting bolt 5 and the outer shell after adjustment, which affects the accuracy of the airflow output. The adjusting bolt 5 is close to the airflow adjustment seat 7. A connecting rod 6 is provided at one end, and the connecting rod 6 is fixedly connected to the adjusting bolt 5. The connecting rod 6 is fixedly connected to the adjusting bolt 5. At the same time, its circumference is tangent to the airflow adjustment seat 7. When the adjusting bolt 5 drives the connecting rod 6 to move downward synchronously, the connecting rod 6 pushes the airflow adjustment seat 7 to rotate, so as to change the different degrees of contact between the alignment notch 12 and the alignment protrusion 13.

[0023] Advantageously, a positioning shaft 10 is fixedly disposed in the fixing seat 8, the adjusting sleeve 11 is sleeved on the positioning shaft 10 via a torsion spring 9, the first leg of the torsion spring 9 is fixedly connected to the adjusting sleeve 11, and the second leg thereof is fixedly connected to the fixing seat 8, the airflow adjusting seat 7 is fixedly connected to the adjusting sleeve 11, both ends of the positioning shaft 10 are fixedly connected to the fixing seat 8, the adjusting sleeve 11 is sleeved on the positioning shaft 10, the adjusting sleeve 11 can rotate along the positioning shaft 10, the airflow adjusting seat 7 is sleeved with a torsion spring 9, and the torsion spring 9 The first leg is inserted into the adjusting sleeve 11, and the second leg is fixedly connected to the fixing seat 8. When the torsion spring 9 is in the uncompressed initial state, the airflow adjusting seat 7 fixedly connected to the adjusting sleeve 11 is in contact with the top of the fixing seat 8. However, when the adjusting bolt 5 drives the airflow adjusting seat 7 to rotate along the positioning axis 10, the torsion spring 9 is gradually compressed. After the alignment notch 12 contacts the alignment protrusion 13, the torsion spring 9 is completely compressed and stores elastic potential energy. After the adjusting bolt 5 is moved up for adjustment, the torsion spring 9 drives the adjusting sleeve 11 and the airflow adjusting seat 7 to reset.

[0024] Beneficially, an active airflow outlet 16 is formed at one end of the airflow regulating seat 7 away from the active airflow inlet 2, and the active airflow inlet 2 is connected to the active airflow outlet 16, and the active airflow outlet 16 is connected to the airflow channel 15. The active airflow outlet 16 is used to be interconnected with the interior of the fixed seat 8, so as to output the airflow in the fixed seat 8 to the airflow channel 15, and output an airflow of a certain pressure value through the airflow regulating seat 7 to meet the uniform air selection of the tobacco.

[0025] Advantageously, a high-pressure air chamber 17 is formed in the shell 1 , and the high-pressure air chamber 17 is located on one side of the airflow channel 15 . The high-pressure air chamber 17 is connected to the active airflow inlet 2 , and the airflow is stored in the high-pressure air chamber 17 to meet the required airflow volume in the airflow channel 15 .

[0026] Advantageously, a high-pressure jet nozzle 4 is formed on the high-pressure air cavity 17, and the output end of the high-pressure jet nozzle 4 is connected to the active airflow inlet 2. The output end of the high-pressure jet nozzle 4 delivers high-pressure airflow into the high-pressure air cavity 17 to provide sufficient high-pressure air flow for the air selection of tobacco.

[0027] Beneficially, the high-pressure air chamber 17 is connected to the interior of the fixed seat 8 through the active airflow inlet 2, and its conduction state and conduction flow rate are controlled by the airflow adjustment seat 7. By controlling the relative position between the alignment notch 12 and the alignment protrusion 13, the size of the conduction opening of the high-pressure air chamber 17 through the fixed seat 8 and the airflow channel 15 bracket is changed, thereby achieving control of the pressure and airflow rate of the airflow output from the airflow channel 15.

[0028] Working principle of this utility model:

[0029] The airflow is delivered to the high-pressure air chamber 17 through the high-pressure jet nozzle 4. The high-pressure air chamber 17 delivers the high-pressure airflow from the active airflow inlet 2 to the active airflow outlet 16. The active airflow outlet 16 delivers the airflow to the airflow channel 15. The output end of the airflow channel 15 evenly delivers the airflow to the tobacco wind selection device to achieve uniform wind selection of tobacco and avoid empty cigarettes.

[0030] Among them, when the active airflow inlet 2 conveys airflow in the fixed seat 8, the airflow adjustment seat 7 can adjust and control the conduction state and the size of the conduction opening. By rotating the adjusting bolt 5, the top of the adjusting bolt 5 and the shell 1 are threadedly matched, and the installation height of one end of the adjusting bolt 5 in the fixed seat 8 can be changed. Since one end of the adjusting bolt 5 is fixedly connected with a connecting rod 6, the connecting rod 6 is tangent to the airflow adjustment seat 7, the airflow adjustment seat 7 is fixedly connected to the adjusting sleeve 11, and the adjusting sleeve 11 is rotatably connected in the fixed seat 8, the downward movement of the adjusting bolt 5 changes the rotation of the airflow adjustment seat 7. The rotation of the airflow adjustment seat 7 can make the alignment notch 12 and the alignment protrusion 13 contact or move away from each other, thereby effectively changing the conduction state and the conduction opening size between the high-pressure air cavity 17 and the inside of the fixed seat 8, and realizing effective control of the pressure value of the conveyed airflow;

[0031] Among them, the circumferential surface of the adjusting sleeve 11 is sleeved with a torsion spring 9, which can realize the reset of the airflow adjusting seat 7 after rotation. However, when the alignment notch 12 contacts the alignment protrusion 13, the conduction between the inside of the fixed seat 8 and the high-pressure air cavity 17 is blocked. At this time, the torsion spring 9 is compressed and stores elastic potential energy. During the gradual upward movement of the adjusting bolt 5, the adjusting sleeve 11 gradually rotates under the reset action of the torsion spring 9, so that the conduction size between the active airflow inlet 2 and the inside of the fixed seat 8 gradually increases. The pressure value and delivery amount of the airflow input to the active airflow inlet 2 are controlled by the airflow adjusting seat 7, and the output pressure value at the output end of the airflow flow channel 15 can be changed to avoid uneven air selection of tobacco and the formation of vortex above the throwing roller due to insufficient air supply, thereby avoiding quality problems such as empty cigarettes caused by uneven air selection.
