Damping dustproof shell for fan

Abstract

The invention relates to the technical field of fan shells, and discloses a damping dustproof shell for a fan. The damping dustproof shell comprises a front protective shell and a rear cover shell, wherein a fixing plate is fixedly installed inside the front protective shell, a motor mounting groove is fixedly formed in the other end of the fixing plate, and a first supporting leg is fixedly connected to the right side of the bottom of the front protective shell. According to the damping dustproof shell for the fan, a plurality of damping structures are arranged inside the supporting leg at the bottom of the fan shell, so that the vibration feeling generated in the using process of the fan is relieved; when the fan is used and vibrates, the fan shell can generate the vibration feeling dueto the rotation of an internal motor, at the moment, first damping springs inside the supporting leg can generate buffer elastic force due to the vibration pressure from a buffer plate, so that the vibration amplitude of the fan shell is relieved; and second damping springs can generate buffer elastic force due to the vibration extrusion of a supporting plate, so that the vibration amplitude of the supporting plate is relieved, and therefore the vibration feeling in the using process of the fan is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fan casings, in particular to a shock-absorbing and dustproof casing for fans. Background technique [0002] Fan refers to a device used to generate wind to keep cool in hot weather. An electric fan is a device driven by electricity to generate airflow. After the fan is powered on, it rotates and turns into natural wind to achieve the effect of enjoying the cool. The fans are divided into two types: desktop and floor-standing. These two types of electric fans are generally divided into There are two kinds of standard popular type and electronic luxury type. The former is characterized by simple structure, convenient operation, and low price. Generally, it only has two functions of speed regulation and changing wind direction, while the latter is characterized by complex and changeable functions and luxurious and exquisite shape. Consumers can choose according to the premise of practicality or the purpos...

Problems solved by technology

[0003] Existing desktop fan shells have a single function and can only be used to protect and support the internal motor, fan blades, and electronic components. Existing fans are prone to vibration during use. If the bottom of supports such as desktops and cabinets Unevenness makes it easy to be shaken and shake noise, and the fan blade is easy to absorb dust after a long time of deep feeling
