Abstract

本实用新型提供一种带挡风板的无叶风扇，包括出风罩，所述出风罩的后方设置有挡风板。本实用新型提供的无叶风扇通过在出风罩的后方加装挡风板，防止冷风从出风罩的后方渗入，增强出风罩吹出的暖风的效果。

Description

一种带挡风板的无叶风扇
技术领域
本实用新型涉及风扇技术领域，特别涉及一种带挡风板的无叶风扇。
背景技术
市面上一般的风扇都是带扇叶的，日常使用中存在安全隐患，儿童的手容易伸进风扇面罩被风扇叶割伤；在清洁方面也极为不便，需要拆开面罩和扇叶才能进行清洁。现有技术提供一种无叶风扇，但是该无叶风扇由于在出风罩的后方具有空隙，容易导致冷风渗入该无叶风扇的出风罩，在使用暖风时，由于冷风的渗入，导致出风罩吹出的暖风温度不高，
实用新型内容
本实用新型提供一种防止冷风从后方渗入的无叶风扇。
为了实现上述目的，本实用新型提供以下技术方案：
一种带挡风板的无叶风扇，包括出风罩，所述出风罩的后方设置有挡风板。
优选地，所述挡风板为全密封或者半密封的装设在所述出风罩的后方。
优选地，所述挡风板为圆形或方形。
优选地，所述挡风板通过卡扣或者通过螺丝钉的方式装设在所述出风罩的后方。
通过实施以上技术方案，具有以下技术效果：本实用新型提供的带挡风板的无叶风扇通过在出风罩的后方加装挡风板，防止冷风从出风罩的后方渗入，增强出风罩吹出的暖风的效果。
附图说明
图1为本实用新型实施例提供的带挡风板的无叶风扇的分解图；
图2为本实用新型实施例提供的带挡风板的无叶风扇的装配图(侧视)；
图3为图2的A处放大图。
具体实施方式
为了更好的理解本实用新型的技术方案，下面结合附图详细描述本实用新型提供的实施例。
本实用新型实施例提供一种带挡风板的无叶风扇，如图1、图2和图3所示，该无叶风扇包括底座111，所述底座111上固定设置有大身112，所述底座111上设置有功能按钮，所述大身112的下方设置有进气口，所述大身112上方设置有出风罩113，所述出风罩113上设置有出风缝口，所述大身112内部装设有蜗轮。其中，所述出风罩113的后方设置有挡风板101。优选地，所述挡风板101为全密封或者半密封的装设在所述出风罩113的后方。优选地，为全密封的装设在出风罩113的后方，防止冷风从出风罩的后方渗入，增强出风罩吹出的暖风的效果。所述挡风板101可以卡扣或者通过螺丝钉的方式装设在出风罩113的后方。
在本实施例中，所述挡风板101为圆形或方形，也可以为其他任何形状的挡风板。
以上对本实用新型实施例所提供的一种带挡风板的无叶风扇进行了详细介绍，对于本领域的一般技术人员，依据本实用新型实施例的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
