Description

吸尘器及吹风机 技术领域
本发明涉及吸尘器及吹风机，尤其涉及一种可提升散热效果的吸尘器及吹风机。
背景技术
现有吸尘器具有一机多用的功能，例如，中国专利申请CN200720152064.9揭露一种干湿两用吸尘器，包括桶体，该桶体上端安装有一上盖，该上盖上设有一凹腔，该凹腔底壁上设有一与桶体相通的通孔，桶体内设有一过滤器，该过滤器设于凹腔下端并覆盖通孔，上盖上还安装有一可与该上盖分开并可单独使用的电动吹风机，该电动吹风机设有一进风口和一排气口，进风口置于凹腔内，并引导桶体内气体经过滤器及通孔后从排气口排出，电动吹风机上还设有手柄，该手柄上设有能控制电机通断的电源开关，吸尘器清洗完地面后，地面不可能马上就干，此时，把电动吹风机从上盖上取出，可以很轻便的提着对地面进行吹干，而不需要拖着整台的吸尘器。另外，该电动吹风机还可以用作吹聚室外地板或草丛中杂物。
为解决一机多用的吸尘器的散热问题，会在吹风机的壳体上设有与外界相通的散热孔，但是，当吹风机从吸尘器上取下并手持使用时，散热孔有可能靠近用户的身体一侧，散热孔的入口可能会被用户的衣物堵住，不利于散热。
