In this example, the airflow adjusting member 15 includes a holder 151, an elastic member 152, a slider 153, an elastic member 154, and a base 155.

It should be noted that the connecting post 1514 and the plurality of projections 1513 can be integrally formed on the inner surface of the frame 151.

It is also feasible that the holder 151 is provided with a movable shaft, the blocking portion 1531 is provided with a fixed hole, and the movable shaft is matched with the fixed hole. At this time, a fixing hole is provided at one end of the connecting post 1514.

An end of the holder 151 facing the second opening 112 has a cavity (not shown in the drawings) capable of receiving at least a portion of the blocking portion 1531. The barrier 1531 has a shape generally corresponding to the shape of the chamber. When the slider 153 moves longitudinally (in a direction from the second opening 112 to the first opening 111) relative to the holder 151 according to the pressure of the airflow, a portion of the blocking portion 1531 may be accommodated in the chamber, so as to change the size of the airflow opening a to control the flow rate of the airflow.

The base 155 is movably connected with one end of the sliding block 153 facing the second opening 112; the base 155 has an air flow through hole 1551, and an end of the slider 153 facing the second opening 112 has a blocking portion (1534, 1535) for at least partially blocking the air flow through hole 1551, so that an air flow opening B is formed between the blocking portion (1534, 1535) and the air flow through hole 1551.

In this example, the barrier includes an airflow cavity 1534 and an extension arm 1535; airflow chamber 1534 is formed by slider 153 recessed inwardly toward an end of second opening 112, and extension arms 1535 extend from an inner surface of airflow chamber 1534 to an exterior of airflow chamber 1535. The airflow chamber 1534 may provide some air resistance to the airflow flowing in from the airflow through hole 1551.

The base 155 is provided with a fixing shaft 1552, the extension arm 1535 is provided with a movable hole 1536, and the fixing shaft 1552 is matched with the shaft hole of the movable hole 1536. An elastic member 154 is disposed between the fixed shaft 1552 and the movable hole 1536, for example: compressing the spring.

The base 155 is hollow, a plurality of projections 1553 are arranged on the inner surface of the base 155, and a connecting column 1554 is arranged inside the base 155; a plurality of protrusions 1553 extend from the inner surface of the base 155 to the connection posts 1554, and airflow through holes 1551 are formed between two adjacent protrusions 1553; a fixed shaft 1552 extends from one end of the connecting column 1554 to the outside of the base 155.

It should be noted that the connecting post 1554 and the plurality of protrusions 1553 can be integrally formed on the inner surface of the base 155.

It is also possible to have a movable shaft on the base 155 and a fixed hole on the extension arm 1535, similar to that described above, with the movable shaft engaging the fixed hole. At this time, the fixing hole is provided at one end of the connection column 1554.

The end of the base 155 facing the first opening 111 has a chamber (not shown) that can receive at least a portion of the stops (1534, 1535). The shape of the barrier (1534, 1535) substantially corresponds to the shape of the chamber. When the slider 153 moves longitudinally relative to the base 155 (in the direction from the first opening 111 to the second opening 112) according to the pressure of the airflow, a portion of the blocking portion (1534, 1535) is received in the cavity, thereby changing the size of the airflow opening B to control the flow rate of the airflow.

The elastic force of the

elastic members

152 and 154 can be set by the user, and different control effects can be generated by setting different elastic forces.

The following description will be made by taking as an example that the elastic force of the elastic member 152 is larger than the elastic force of the elastic member 154:

since the elastic force of the elastic member 152 is greater than that of the elastic member 154, the initial position of the slider 153 is closer to the base 155 under the condition that the user does not suck, and the gap (air flow opening B) between the slider 153 and the base 155 is dominant in controlling the flow rate of the air flow.

When the user's suction force is small, the gap between the slider 153 and the base 155 is small, and the flow rate of the air flow is small.

When the suction force is gradually increased (at this time, the pressure of the slider 153 toward the end of the first opening 111 is smaller than the pressure of the slider 153 toward the end of the second opening 112), the slider 153 moves toward the first opening 111, the gap between the slider 153 and the base 155 gradually increases, and the flow rate of the air flow also increases. At the same time, the gap (air flow opening a) between the slider 153 and the bracket 151 is also reduced (not completely closed), and the suction resistance is increased, so that the flow rate of the air flow can be stabilized within a range, and the flow rate increase of the air flow can be controlled to the maximum extent.

It can be understood that when the elastic force of the elastic component 152 is smaller than the elastic force of the elastic component 154, the initial position of the slider 153 is closer to the bracket 151, and the gap (air flow opening a) between the slider 153 and the bracket 151 dominates the flow rate of the control air flow.

In the examples of fig. 1 to 11, the holder 151 and the base 155 are described as an example. In other examples, only the bracket 151 or the base 155 may be implemented.
