When passing through normally, at this time, when the airflow flows in the casing 100, such as in the first chamber 101, its path tends to be straight, that is, the path is relatively short; and when the airflow velocity in the casing 100 is relatively high, If the blower 301 and the exhaust fan 401 are activated at the same time, at this time, the high-velocity airflow in the housing 100 causes the spoiler to rotate at a certain angle relative to the second partition plate 200 . As shown in FIG. 2 , the airflow is in the first chamber 101 When flowing inside, the flow path becomes a broken line path, that is, the effect of extending the path of the airflow in the casing 100 is achieved, and the sterilization of the airflow caused by the ultraviolet lamp 500 caused by the rapid passage of the airflow through the casing 100 is avoided. The problem of unsatisfactory disinfection effect.

fixedly connect the deflector 800 installed on the circular shaft 801;

An elastic support member engaged with and linked with the driven pinion 802 is provided on the second partition plate 200 .

Further, in the preferred embodiment provided by the present invention, a sealing connection cloth 203 is also connected between the second partition plate 200 and the baffle plate 800 to prevent the adjacent first chamber 101 from being Air circulation occurs between the two chambers 102 through the linkage channel 202 .

In the specific implementation process of the spoiler provided by the embodiment of the present invention, as shown in FIG. 1 , when the airflow enters the first chamber 101, it circulates through the channel between the guide plate 800 and the baffle 600, The position of the airflow passage changes with the position of the end of the baffle plate 800, and the airflow velocity increases, so that when the angle of the baffle plate 800 relative to the second partition plate 200 changes, as shown in FIG. 2, the airflow The position of the circulation channel is moved downward, so that the flow path of the airflow in the first chamber 101 is in a folded line shape, thereby extending the flow path of the airflow in the first chamber 101 to a certain extent, and improving the convection flow through the housing 100. Sterilization effect of airflow.

Therefore, the angle of the deflector 800 in the first spoiler changes. At the time of rotation, the circular shaft 801 of the first spoiler can be driven to rotate by a moving angle, and then the driven pinion 802 of the first spoiler can move the toothed plate 204 for a certain distance. At the same time, the moving toothed plate 204 makes the first The angles of the baffles 800 of the two spoilers change synchronously. Therefore, while the baffles 800 of the first spoiler effectively extend the path of the airflow in the first chamber 101, the The baffle 800 can also effectively extend the path of the airflow in the second chamber 102 .

Further, as shown in FIG. 3 and FIG. 5 , in the embodiment of the present invention, the slider 206 is further provided with a first ventilation hole 208 , and a space between the support cavity 205 and the linkage channel 202 is formed. A second ventilation hole 209 is also opened on the board to achieve the effect of equalizing the air pressure in the support cavity 205 when the slider 206 moves in the support cavity 205 .
