Abstract

The invention discloses a cowl and a ventilation system. According to the cowl and the ventilation system, the technical problems that as for an existing cowl, leakage of rain is likely to occur, airflow is difficult to disperse, the occupied space is large, and manufacturing and mounting are difficult are solved. The cowl comprises a cowl body, an air inlet flow guide plate and an air outlet flowguide plate. The cowl body comprises an air outlet side plate and a cover plate fixed to the top of the air outlet side plate in an airtight mode, the air outlet side plate is in an inverted-pyramid-frustum cylinder shape and is provided with air outlets, and a cowl air inlet is formed in the bottom of the air outlet side plate. The air inlet flow guide plate is fixed in the cowl body and guidesairflow entering from the cowl air inlet to the air outlets of the air outlet side plate. The air outlet flow guide plate is fixed to the outer side of the air outlet side plate, comprises a side plate part and a bottom plate part connected with the bottom of the side plate part, and guides the airflow exhausted from the air outlets to the upper portion of the cowl, and the bottom plate part is inairtight connection with the air outlet side plate and is provided with a drainage hole.

Description

Technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a hood and a ventilation system. Background technique [0002] Ventilation is a building environment control technology that controls the spread and harm of air pollutants by means of ventilation dilution or ventilation elimination, and achieves indoor and outdoor air environment quality assurance. The ventilation system is to realize the function of ventilation, including a complete set of devices including suction vents, exhaust vents, ventilation ducts, ventilators, control systems and other auxiliary equipment. [0003] In the existing ventilation system, such as figure 1 As shown, the rectangular air outlet of the ventilator 002 is connected to the round umbrella-shaped hood 001 through a reducing pipe 003 with a rounded opening on one side. The inventor of the present application discovered during the implementation of the present application that the structural hoo...
