In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments.

Referring to fig. 1 and 2, the present invention provides a wind box, which includes a box body 10, a filter structure 20, a baffle 30, a driving member 50 and a discharge pipe 40. The bellows is used for connecting to an air conditioner of a vehicle and for passing an air flow.

Referring to fig. 2, the box 10 has a ventilation channel 90, an air inlet 102 and an air outlet 101 are respectively formed at two ends of the ventilation channel 90, and the ventilation channel 90 is used for allowing air flow to flow from the air inlet 102 to the air outlet 101. The intake vent 102 may face the outside of the vehicle and the outlet vent 101 may face the air conditioner inside the vehicle. When the air conditioner is started, negative pressure is generated at the air outlet 101 of the box 10, so that external air enters the ventilation channel 90, and airflow is formed in the ventilation channel 90 and flows to the air outlet 101.

In this embodiment, the inlet 102 faces upward, and the outlet 101 faces horizontally.

Referring to fig. 2, the filter structure 20 is disposed in the ventilation channel 90 and blocks a portion of the ventilation channel 90, and the filter structure 20 and the inner wall of the ventilation channel 90 together enclose to form a communication hole 103. It will be appreciated that the filter structure 20 does not completely block the vent passage 90 but instead blocks a portion of the vent passage 90, bypassing a portion of the vent passage 90, the bypassed portion forming the communication aperture 103. The filter structure 20 is capable of filtering dust or impurities in the air, which means blocking the dust or impurities from passing through the filter structure 20, and large particles of dust or impurities can also fall down along the filter structure 20.

In this embodiment, the filter structure 20 is located in the middle of the ventilation channel 90, the cross section of the middle is square, the edge of the filter structure 20 abuts against the upper half cavity wall of the ventilation channel 90, the lower surface of the filter structure 20 is located above the lower cavity wall of the ventilation channel 90 and is spaced from the lower cavity wall, and the lower half cavity wall of the ventilation channel 90 and the lower surface of the filter structure 20 together enclose to form the communication hole 103.

Wherein, the filtering structure 20 can be a filtering net or a filtering core, and the filtering structure 20 can be a flat cake-shaped structure.

In other embodiments, the filter structure 20 may be disposed at the intake 102 or the outtake 101.

When air flows through the ventilation channel 90, the air flow passes through the communication hole 103 mostly and passes through the filter structure 20 only partially due to the large wind resistance of the filter structure 20, and thus the air flow cannot filter air. In this regard, referring to fig. 2 and 3, the bellows is further provided with a flap 30, the flap 30 being switchable between a first position and a second position. When the baffle 30 is in the first position, the baffle 30 shields the filter structure 20 and at least partially avoids the communication holes 103, and the airflow only flows through the communication holes 103 and does not pass through the filter structure 20; when the baffle 30 is in the second position, the baffle 30 blocks the communication hole 103 and at least partially avoids the filter structure 20, at this time, the air flow cannot pass through the communication hole 103 and can only flow through the filter structure 20, at this time, the filter structure 20 can filter the whole air flow so as to fully block dust or impurities in the air flow.

In this embodiment, the cross-sectional area of the baffle 30 is equal to or greater than the cross-sectional area of the filter structure 20, and the baffle 30 may be disposed parallel to the filter structure 20 and move along a plane parallel to the filter structure 20.

The air box is provided with the filtering structure 20 only shielding part of the ventilation channel 90 and the baffle 30 capable of switching between a first position shielding the filtering structure 20 and a second position shielding the communication hole 103, when the external air quality reaches the standard, the baffle 30 is switched to the first position, so that the airflow in the ventilation channel 90 flows from the air inlet 102 to the air outlet 101 through the communication hole 103, and the air speed and the air volume of the airflow are ensured, when sand and dust exist in the external air, the baffle 30 is switched to the second position, so that the airflow in the ventilation channel 90 can flow to the air outlet 101 after being filtered by the filtering structure 20 through the air inlet 102, and the air exhausted from the air outlet 101 is clean air, thus, the air output and the air speed of the air conditioner when the external air reaches the standard are ensured, the normal power of the air conditioner is ensured, and the air can be filtered when the sand and dust exist in the external air, the user experience is improved.

Referring to fig. 2, the baffle 30 may be located on a side of the filter structure 20 near the air inlet 102 when the baffle 30 is in the first position, so as to block the filter structure 20 from contacting the air flow entering the air inlet 102 when the air enters. When the baffle 30 is in the second position, the horizontal side and lower surface of the baffle 30 abut against the wall of the lower half of the ventilation channel 90.

In the embodiment, referring to fig. 2 and 3, the filter structure 20 is located above the communication hole 103, so that after the filter structure 20 filters the airflow, the dust particles filtered from the filter structure 20 can fall down and further fall off the filter structure 20, thereby preventing the filter structure 20 from being blocked due to the accumulation of the dust particles after a long time of use. At this time, the shutter 30 can move up and down, and the first position of the shutter 30 is located above the second position.
