Airflow guiding member and air duct with airflow guiding member

Abstract

The air duct comprises a body and at least an airflow guiding member. The airflow guiding member is detachably configured in a slot outlet of the body. The airflow guiding member comprises a guiding ditch with a receiving section, a regulating section, and a guiding section. An airflow flowing in the body is received by the receiving section into the regulating section and then thrusts out of the body after sequentially compressed by the regulating and guiding sections. An air wall is as such formed above the body to confine the pollutants dispersed in the air.

I claim:

         2 . The air duct according to  claim 1 , wherein the guiding ditch is configured on the airflow guiding member along the axial direction of the body, and penetrates through the airflow guiding member along a radial direction of the body; the receiving and regulating sections are perpendicular to an axle of the body; and the guiding section is slant to the regulating section. 
     
     
         3 . The air duct according to  claim 1 , wherein the airflow guiding member further comprises a main element and a panel; the panel is configured on the main element; the guiding ditch penetrates through the main element with the guiding section penetrates through the panel; the main element's width is compatible with that of the slot outlet; the panel's width is greater than that of the slot outlet; and the airflow guiding member has its main element plugged into the slot outlet and its panel joined to the body. 
     
     
         4 . The air duct according to  claim 1 , wherein the airflow guiding member further comprises a joining part and a support part; the receiving section penetrates through the joining part; the regulating and guiding sections penetrate through the support part; the joining part has a width compatible with that of the slot outlet; the support part has a width greater than that of the slot outlet; and the airflow guiding member has the joining part embedded in the slot outlet, and the support part against the air duct. 
     
     
         5 . The air duct according to  claim 1 , further comprising a plurality of airflow guiding members arranged in the slot outlet along the axial direction of the body. 
     
     
         6 . The air duct according to  claim 5 , wherein, for two adjacent airflow guiding members of the plural airflow guiding members, one has a bulge and the other has a notch compatible to the bulge; and the two adjacent airflow guiding members are connected by having one's bulge embedded into the other's notch. 
     
     
         7 . The air duct according to  claim 1 , wherein the airflow guiding member further comprises at least a through hole and an axial rod; the through hole is configured on the airflow guiding member along the axial direction of the body; and the axial rod is threaded through the through hole. 
     
     
         8 . An airflow guiding member configured in a slot outlet of an air duct, the air duct having an airflow inside, the airflow flowing outside the air duct through the airflow guiding member, wherein the airflow guiding member is characterized in that:
 the airflow guiding member is detachably configured in the slot outlet; the airflow guiding member comprises a guiding ditch with a receiving section, a regulating section, and a guiding section; the regulating section is connected between the receiving and guiding sections; the receiving section has a greater width than that of the regulating section, which in turn has a greater width than that of the guiding section; the airflow is received by the receiving section into the regulating section and then thrusts out of the air duct after sequentially compressed by the regulating and guiding sections.   
     
     
         9 . The airflow guiding member according to  claim 8 , further comprising a main element and a panel; the panel is configured on the main element; the guiding ditch penetrates through the main element with the guiding section penetrates through the panel; the main element's width is compatible with that of the slot outlet; the panel's width is greater than that of the slot outlet; and the airflow guiding member has its main element plugged into the slot outlet and its panel joined to the air duct.
