Description
技术领域technical field
本发明涉及扫地机器人技术领域，具体的涉及一种具有吸附力强的扫地机的风扇机构。The invention relates to the technical field of sweeping robots, in particular to a fan mechanism of a sweeping machine with strong adsorption force.
技术背景technical background
随着人们生活水平的提高和工作的忙碌，家里打扫卫生成为很多人特别是年轻人比较头疼的事情，为了解放家人的双手，空余更多时间享受家庭生活，多采用智能扫地机器人来代替人工；市面上较常规的智能扫地机器人其基本包括智能控制系统、驱动装置和吸附产生负压的装置，通过负压吸附灰尘，通过驱动装置自由行走，通过智能控制系统实现转弯、撤回、后退等功能，实现全面的打扫效果；但是目前市场上的这种扫地机，其吸附力并不是很理想，虽然可以把细小的灰尘、纸屑吸附，但是对于密度较大的物质，比如米粒，粘性面屑等则显得吸附力不够，很难将这些垃圾一并清除干净；之所以会出现上述的不足，主要是由于其中的风扇机构设置的不甚理想，现有技术用于扫地机的风扇机构，一般包括一个与扫地机内的吸收存放垃圾的壳体连接的风道蜗壳，风道蜗壳内安装有电机和电机带动的叶片，风道蜗壳位于电机和叶片的外周将电机好叶片包覆于其中、叶片位于电机上部、电机自蜗壳底部向上延伸并托举叶片基本与蜗壳上边沿等高、且风道蜗壳与电机带动的叶片之间不接触，并且彼此之间有很大的空间间隙；然后通过电机带动叶片高速旋转，风道蜗壳内产生空气负压，然后在负压的作用下灰尘从存放垃圾的壳体的开口被吸附到壳体内储存起来；但是这种风扇结构，由于风道蜗壳与电机带动的叶片之间不接触，并且彼此之间有很大的空间间隙，产生的负压相对较小从而导致吸附效果不理想。With the improvement of people's living standards and busy work, cleaning at home has become a headache for many people, especially young people. In order to free the hands of family members and have more time to enjoy family life, intelligent sweeping robots are often used instead of manual work; The more conventional intelligent sweeping robots on the market basically include an intelligent control system, a driving device, and a device that absorbs negative pressure. It absorbs dust through negative pressure, walks freely through the driving device, and realizes functions such as turning, withdrawing, and retreating through the intelligent control system. To achieve a comprehensive cleaning effect; however, the adsorption force of this kind of sweeper on the market is not very ideal. Although it can absorb fine dust and paper scraps, it is difficult for dense materials, such as rice grains, sticky flour crumbs, etc. Then it seems that the adsorption force is not enough, and it is difficult to remove these rubbish together; An air duct volute connected to the housing that absorbs and stores garbage in the sweeper. A motor and blades driven by the motor are installed in the air duct volute. Among them, the blade is located on the upper part of the motor, the motor extends upward from the bottom of the volute and lifts the blade to the same height as the upper edge of the volute, and there is no contact between the air duct volute and the blades driven by the motor, and there is a large gap between them Space gap; then the motor drives the blades to rotate at high speed, and the air negative pressure is generated in the air duct volute, and then under the action of the negative pressure, the dust is absorbed into the housing from the opening of the housing where the garbage is stored; but this fan structure , because the air duct volute and the blades driven by the motor are not in contact, and there is a large space gap between them, the negative pressure generated is relatively small, resulting in an unsatisfactory adsorption effect.
