Abstract

The invention relates to a bladeless fan. The bladeless fan comprises a nozzle assembly. The nozzle assembly comprises two oppositely-arranged wind outlet portions. A diffusion wind switching assemblyis arranged in the nozzle assembly and comprises a pull plate and a pull rod movably arranged on the pull plate, the pull plate can move up and down, the pull rod can convert up-and-down movement ofthe pull plate into movement towards a wind outlet, opening and closing plates are fixedly arranged at the two ends of the pull rod and correspond to the wind outlet portions, and the opening and closing plates can move towards the wind outlet portions and close the wind outlet portions. By means of the bladeless fan, the two wind outlet portions are arranged on the nozzle assembly, the diffusionwind switching assembly is arranged and can switch the wind outlet portions according to actual requirements, and therefore the wind outlet direction of the nozzle assembly is changed, and use convenience is improved.

Description

technical field [0001] The invention relates to a fan, in particular to a bladeless fan. Background technique [0002] Compared with traditional electric fans with blades, bladeless fans have the characteristics of low noise and safety. The basic structure of the bladeless fan includes a nozzle assembly, a wind wheel assembly and a base. The nozzle assembly of the bladeless fan usually has only one air outlet, and the airflow generated by the wind wheel assembly is blown out along the air outlet of the nozzle assembly. However, the air outlet can only blow air in front of it, and the entire fuselage needs to be rotated when the air outlet direction is to be adjusted, which brings a lot of inconvenience to the user in daily life. Contents of the invention [0003] The purpose of the present invention is to provide a bladeless fan, which can adjust the air outlet direction according to actual needs. [0004] In order to achieve the above object, the present invention provi...
