Abstract

A fan head includes a first cavity and a second cavity each having a column shape, the second cavity is located in the first cavity, the side surface of the first cavity is arranged along the first The side of the second cavity is provided with a second air outlet along the length direction of the second cavity, the opening direction of the second air outlet is different from the direction of theopening of the first air outlet. The bottom surface of the second cavity is provided with an air inlet communicating with the second air outlet; an airflow passage communicating with the second air outlet and the first air outlet is formed between the inner surface of the first cavity and the outer surface of the second cavity. In the fan, the air flow enters and exits the second cavity through the air inlet, and is jetted outward through the second air outlet, the air flow passage and the first air outlet, so that the flow path of the air flow in the fan head increases to eliminate or weakenthe noise effect, and at the same time, the inner and outer two-layer cavities can also play the role of sound insulation, thereby realizing the low-noise fan head and enhancing the user experience.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a fan head and a bladeless fan. Background technique [0002] In the related art, the bladeless fan includes a fan head. The fan head is provided with an air duct and an air outlet. When the bladeless fan is working, the airflow tends to generate a large wind noise at the air outlet, thereby reducing the user experience. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the related art. Therefore, the present invention needs to provide a fan head and a bladeless fan. [0004] A fan head according to an embodiment of the present invention is used for a bladeless fan. The fan head includes a columnar first cavity and a second cavity, and the second cavity is located in the first cavity. The side of the first cavity is provided with a first air outlet along the length direction of the first cavity, and ...
