Abstract

The utility model provides a novel low-noise full-plastic axial flow fan, and belongs to the field of ventilation equipment. The novel low-noise full-plastic axial flow fan eliminates the defects that existing ventilation equipment is complex in manufacturing process, high in cost, environment-contaminated, and high in noise. The novel low-noise full-plastic axial flow fan comprises a cylindric outer shell and a motor. Fan blades are arranged on a motor shaft of the motor in a sleeved mode. An installation frame is arranged in the outer shell. The motor is fixedly installed on the installation frame. The outer shell is made of plastic materials, and is molded in a one-shot mode through compression molding. The novel low-noise full-plastic axial flow fan has the advantages that noise is low, labor cost is saved by over 30%, machining process difficulty is low, low-carbon and environment protection purposes are achieved, and environmental pollution and damage to human bodies caused by spray painting are eliminated.

Description

The overall plastic axial-flow blower of a kind of Novel low noise

One, technical field

The utility model belongs to the ventilation equipment field, and is especially relevant with the overall plastic axial-flow blower of a kind of Novel low noise.

Two, background technique

At present, the axial-flow blower of generally selling on the market, its shell and fan blade all are to adopt the metal group component, and the metal group component has following some shortcoming: 1, complex manufacturing technology, its shell need to just can be finished by process steps such as panel beating, welding, the oven dry of polishing, spray paint, and fabricating cost is high; 2, metal shell and fan blade are too heavy, cause motor load to increase, and are unfavorable for energy-conservationly, and noise is excessive simultaneously, unfavorable environmental protection; 3, the parts such as metal shell and fan blade get rusty easily, and are not acidproof, not alkaline-resisting, cause Environmental Conditions that certain narrow limitation is arranged.

Three, model utility content

The purpose of this utility model will overcome defects exactly, provides that a kind of preparation process is simple, lightweight, noise is little, non-corrosive, corrosion resistant Novel axial flow fan.

For this reason, the utility model provides following technological scheme: the overall plastic axial-flow blower of a kind of Novel low noise, comprise cylinder-like shell and motor, be set with fan blade on the motor shaft of motor, scaffold is set in the shell, motor is fixedly mounted on the scaffold, it is characterized in that: described shell is that plastic material is made, and this shell is by the compression moulding once-through.

As the further of such scheme improved and replenish, the utility model also comprises following technological scheme:

The number of pin of described scaffold is the 2-8 root.

Described scaffold is tripod, is fixedly installed on outer casing inner wall, in the middle of the tripod motor mounting hole is set, and this tripod is that plastic material is made, and with shell while compression molding, is used for installing blower fan.

Described scaffold is T shape support, and this T shape support is that plastic material is made, and with shell while compression molding, is used for installing blower fan.

Described fan blade is that plastic material is made, and can effectively reduce motor load, noise reduction.

The utlity model has following advantage: 1, effectively reduce noise, 2, saving labour turnover reaches more than 30%, 3, reduce the processing technology difficulty, 4, low-carbon environment-friendly, eliminated the environmental pollution and to the human injury of spraying paint.
