Problems solved by technology

[0002] The traditional fan is driven by the motor to rotate the blades to generate wind, accelerate the flow speed of the air flow in the surrounding environment, so as to achieve the effect of cooling and relieving heat and circulating air, but this traditional fan is easy to cause danger, and there is a certain degree of safety. Hidden danger, and inconvenient to clean
[0003] Therefore, there are bladeless fans on the market at present. This kind of fan does not have traditional fan blades, and it relies on the gap to vent the air, so as to achieve the effect of circulating air; the bladeless fans that can be seen on the market now rely on ring shape The nozzle is used to discharge the wind, this single design naturally cannot satisfy people's growing aesthetic taste

Abstract

The invention discloses a bladeless fan comprising a substrate and a flat-and-elongated nozzle. The substrate comprises a substrate shell, air inlet holes and a fan. The air inlet holes are formed in the substrate shell, the fan arranged in the substrate is used for inhaling external airflow from the air inlet holes and generating internal airflow upwards. The nozzle is divided into a left side face, a right side face, a front end and a rear end, the left and right side faces are larger in size, the front and rear ends are smaller in size, the rear end is sealed, and the front end is provided with a slit-shaped outlet. The nozzle is used for receiving internal airflow and ejecting the same out. Designed reasonably, the bladeless fan is higher in safety performance as compared with the common fans, and more attractive in shape than common bladeless fans.

Description

technical field [0001] The invention relates to a fan, in particular to a bladeless fan. Background technique [0002] The traditional fan is driven by the motor to rotate the blades to generate wind, accelerate the flow speed of the air flow in the surrounding environment, so as to achieve the effect of cooling and relieving heat and circulating air, but this traditional fan is easy to cause danger, and there is a certain degree of safety. Hidden danger, and inconvenient to clean. [0003] Therefore, there are bladeless fans on the market at present. This kind of fan does not have traditional fan blades, and it relies on the gap to vent the air, so as to achieve the effect of circulating air; the bladeless fans that can be seen on the market now rely on ring shape The nozzle carries out the wind, and this single design naturally cannot satisfy people's growing aesthetic taste. Contents of the invention [0004] In view of this, the purpose of the present invention is to...
