Problems solved by technology

[0002] In the modern industrial production process or the use of household appliances, the demand for heat dissipation is getting higher and higher, so different types of fans emerge in an endless stream. At present, centrifugal fans are commonly used to dissipate heat for parts that are prone to heat, such as motors. Most of the centrifugal fans are now Fans are composed of a hub and a number of fan blades arranged on the hub. After a long working time, this centrifugal fan will be damaged due to the dust falling into the fan hub and several fan blades or due to the wear of the fan blade itself. It will affect the working quality of the centrifugal fan, reduce or even disappear the heat dissipation effect, and cause accidents such as equipment failure or personnel injury.

Embodiment Construction

[0018] The centrifugal fan proposed by the present invention will be described in further detail below with reference to the drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0019] The core idea of ​​the present invention is to provide a centrifugal fan, which includes a hub, a plurality of fan blades and a protective circular plate, the plurality of fan blades are arranged on the hub at the same angle and in the same direction, and the protective circular plate is set On the plurality of fan blades, the connection mode between the hub and the plurality of fan blades is a detachable connection. The centrifugal fan drives the rotation of the plurality of fan blades t...

Abstract

The invention provides a centrifugal fan, which comprises a hub, a plurality of fan blades and a circular protection plate. The fan blades are annularly arranged on the hub in the same direction at intervals of the same angle, the circular protection plate is arranged on the fan blades, and the hub is detachably connected with the fan blades. By means of the structural design of the centrifugal fan, the working quality of the centrifugal fan can be ensured, the centrifugal fan is convenient to carry and mount, and the service life of the centrifugal fan is prolonged by means of fine protective measures. By the aid of the detachable hub of the centrifugal fan, the fan blades and the circular protection plate on the fan blades can be conveniently detached to clean accumulated dust and impurities, the detached fan blades can be maintained, and cleanness and the working quality of the whole centrifugal fan are kept.

Description

technical field [0001] The invention relates to a fan, in particular to a centrifugal fan. Background technique [0002] In the modern industrial production process or the use of household appliances, the demand for heat dissipation is getting higher and higher, so different types of fans emerge in an endless stream. At present, centrifugal fans are commonly used to dissipate heat for components that are prone to heat such as motors. Now most of the centrifugal fans are Fans are composed of a hub and a number of blades arranged on the hub. After a long working time, this kind of centrifugal fan will fall into the fan due to the dust on the hub and the blades or the wear of the blades themselves. It affects the working quality of the centrifugal fan, reduces or even eliminates the effect of heat dissipation, and causes accidents such as equipment failure or personnel injury. Contents of the invention [0003] The invention provides a centrifugal fan to protect the fan blad...
