Abstract

The invention relates to the field of air supply equipment, in particular to an air outlet grating and an air outlet device. The air outlet grating is provided with a first air inlet which is axiallyformed, and an air outlet and a second air inlet which are circumferentially formed, the air outlet is located between the first air inlet and the second air inlet, first grating ribs and second grating ribs which are connected in a crossed mode are arranged at the air outlet, and the first grating ribs are arranged in a spiral structure in the axial direction of the air outlet grating in an extending mode. The strength of the air outlet grating is good, the air outlet mode is improved by the first grating ribs in the spiral structure, the air supply efficiency is improved, the air outlet noise is reduced, double centrifugal impellers are assembled on the air outlet grating, air inflow from the first air inlet and the second air inlet is achieved at the same time, air is output from the peripheral side of the air outlet grating, the air outlet volume is large, and the air outlet effect is good.

Description

technical field [0001] The present application generally relates to the field of air supply equipment, and in particular, relates to an air outlet grille and an air outlet device. Background technique [0002] Nowadays, people's quality of life is constantly improving, and the requirements for electric fans are not limited to the situation of large air volume, but also pay more attention to the comfort of electric fans. The combined structure of grid ribs and longitudinal grid ribs makes the wind resistance of the air outlet grille large, the air outlet is not smooth, and the airflow passing through the grille will generate certain noise. Contents of the invention [0003] A series of concepts in simplified form are introduced in the Summary of the Invention, which will be further detailed in the Detailed Description. The contents of this application do not mean to attempt to limit the key features and essential technical features of the claimed technical solution, nor to...
