Description

Technical Field

[0001] This utility model relates to the field of hand dryer technology, specifically to a hand dryer housing and hand dryer that are easy to install and fit. Background Technology

[0002] A hand dryer is a device that dries or warms hands by blowing air. After washing your hands, simply place them under the air outlet of an automatic hand dryer, and it will automatically deliver a comfortable breeze to quickly dry your hands. This eliminates the need to use a towel to dry your hands and helps prevent cross-infection of diseases.

[0003] Existing hand dryers typically incorporate two air outlets to increase the drying area and improve efficiency. However, this design requires at least two sensors to control the airflow for proper operation. The installation of these sensors is cumbersome, as their placement necessitates precise alignment with the outer casing; even slight errors can lead to significant installation difficulties. Therefore, it is essential to improve upon existing technology to overcome these shortcomings. Summary of the Invention
