The vehicle-mounted unpowered air supply nozzle comprises a fixed rack and at least one set of peripheral ventilation assemblies, the fixed rack is arranged in an airflow pipeline so as to divide the airflow pipeline into an air inlet end and an air outlet end, and the peripheral ventilation assemblies are arranged on the fixed rack; the central disturbance pipe is arranged in the air inlet end; the movable push plate is arranged in the air inlet end of the airflow pipeline and can reciprocate in the air inlet end under the action of airflow; an air outlet of the central disturbance pipe is formed in the center of the fixed rack and communicates with the air outlet end, and at the initial position, a part of the air inlet is located on the side, away from the fixed rack, of the movable push plate so that airflow can flow out through the air outlet; in the middle position, one part of the air inlet and one part of the air inlet are located on the side, away from the fixed rack, of the movable push plate so that airflow can flow out through the air outlet and the air outlet. The high-speed airflow columns and the low-speed airflow columns which are alternately generated can form a vortex ring, an additional power mechanism is not needed, the weight of the device is reduced, and use convenience is guaranteed.
本发明公开了车载无动力送风喷口,包括固定机架和至少一组周边通风组件,固定机架设置在气流管道内,以将气流管道分隔成进气端和出气端,还包括设置在进气端内的中央扰动管以及设置在气流管道的进气端内、能够通过气流作用在进气端内往复移动的移动推板;中央扰动管的出风口设置在固定机架的中心处、且出风口和出气端连通,在初始位置,进风口的一部分位于移动推板远离固定机架的一侧,以通过出风口流出气流;在中间位置,进风口的一部分和进气口的一部分位于移动推板远离固定机架的一侧,以通过出风口和出气口流出气流。本发明交替产生的高速气流柱和低速气流柱可形成涡环,无需额外动力机构,减轻了装置的重量、并保证了使用的便捷性。
