The invention discloses a machine head for a bladeless fan and the bladeless fan. The machine head comprises an air outlet part and an air inlet part; the air outlet part is provided with an air outlet flue and comprises a first air outlet section and a linear second air outlet section; the first air outlet section and the second air outlet section are connected, and the first air outlet section is connected to the lower end of the second air outlet section; the air outlet flue penetrates through the first air outlet section and the second air outlet section, the inner wall face of the air outlet flue is provided with an arc first flow guide face in the first air outlet section, and the first flow guide face extends to the second air outlet section; the air outlet part is provided with anair outlet which communicates with the air outlet flue; the first air outlet section is connected with the air inlet part and the second air outlet section; and the air inlet part is provided with anair inlet, and the air outlet flue communicates with the air inlet and the air outlet. Thus, the probability of occurrence of vortexes can be decreased, and noise is reduced.
Description
technical field [0001] The invention relates to the field of household electrical appliances, in particular to a machine head for a bladeless fan and the bladeless fan. Background technique [0002] In the related art, when the airflow generated by the bladeless fan enters the air duct of the head of the bladeless fan, the airflow is prone to vortex, especially when the flow direction of the airflow changes, the change of the direction of the airflow is more likely to cause The airflow generates eddy currents, and the above situations will lead to increased noise when the bladeless fan is working, affecting 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 head for the bladeless fan and the bladeless fan. [0004] According to the embodiment of the present invention, the machine head used for the bladeless fan inclu...
