Bladeless fan structure

Abstract

The invention relates to a fan, in particular to a housing structure of a bladeless fan. The bladeless fan structure is characterized by comprising a housing; a passage capable of accommodating a fan component is disposed inside the housing; two ends of the passage are connected end to end; the center of the housing is provided with a through hole; the through hole is formed by enclosing and connecting the passage end to end; the front end face of the housing is provided with an air outlet; the rear end face of the housing is provided with an air inlet. The structure is simple in structure and fine in outlet effect, the housing rarely deforms, and the structure can be used with the fan component to form a bladeless fan low in operation noise; the technical problem that the housing of the prior bladeless fan needs a partition device for the air outlet, has high processing requirements, has many parts and produces resonance easily is solved.

Description

technical field

[0001] The invention relates to a fan, in particular to a shell structure of a bladeless fan. Background technique

[0002] A traditional fan usually includes a motor, fan blades, a base or a fixed frame, a power supply, and the like. When the power is turned on, the motor rotates, driving the blades on the motor shaft to rotate, and the rotating blades generate airflow. Therefore, as the heat is taken away by convection and evaporation, the user feels the cooling effect within the range of the airflow. Now some improvements have been made to the traditional fan, that is, the fan with blades has been improved to the fan without blades. Now there are many introductions about bladeless fans. Such as the Chinese patent: "Fan (CN101749289A)", which describes a fan assembly for forming airflow, the fan assembly includes a nozzle mounted on a base bearing device, and the base bearing device is used to form an airflow passing through the nozzle . The nozzle inclu...
