Description

一种家用洗地机 技术领域
本发明涉及智能家居技术领域，具体涉及一种家用洗地机。
背景技术
现有技术中，洗地机一般分为商用洗地机和家用洗地机，商用洗地机一般用于面积比较大的工厂、车库、商场超市等场所，而家用洗地机一般适用于面积比较小(一般小于200平方米)的家庭。
针对家用洗地机，其结构主要包括依次连接的手柄、洗地机主体和地刷，洗地机主体上主要设有清水箱(以向滚筒供应干净水)、污水箱(以收集污水)和用于抽吸的吸力电机；而地刷内主要设有用于清洗地面的滚筒、用于控制滚筒的滚筒电机、以及喷液装置等。工作时，所述喷液装置处于开启状态，向所述滚筒喷液；所述滚筒电机处于开启状态，使所述滚筒旋转；所述吸力电机处于开启状态，将流过所述滚筒的液体(污水)吸至吸液管道，并最终流入污水箱内。这种小型的家用洗地机因其方便实用而得到了大众的广泛青睐。例如，中国发明专利申请CN110960151A公开了一种清洗机，包括滚刷、水泵和控制器，参见其图6所示，其结构主要包括依次连接的手柄、洗地机主体和地刷，洗地机主体上从上至下依次设有溶液桶50(即清水箱)、吸力电机和污水箱，且三者的轴心线基本同线设置，这种结构具有较好的视觉美感，但存在如下问题：(1)若是为了保证较多的供水量，则溶液桶(即清水箱)和污水箱的容积需要设计得较大，相应的，两个筒体(或箱体)的高度就会比较高，再加上吸力电机的高度，导致整个设备的整体高度较高，对使用者不太友好；而若是为了降低设备的整体高度，势必会减小两个筒体的高度和体积，导致设备的清洁水量降低；因此，这两者成为了一对矛盾，难以兼顾；(2)由于两个筒体和吸力电机都位于洗地机主体的一侧，因此其重心也都在一侧，容易发生侧翻。
因此，开发一种新的家用洗地机，以兼顾洗涤水量和设备的整体高度，且重心更稳，以提高用户体验，显然具有积极的实际意义。
发明内容
本发明的目的是提供一种家用洗地机。
为了达到上述发明目的，采用的技术方案是：一种家用洗地机，主要包括依次连接的手柄、洗地机主体和地刷，所述洗地机主体上设有清水箱、吸力电机和污水箱，所述吸力电机设于所述清水箱的侧边，所述清水箱位于所述污水箱的上方。
上文中，所述吸力电机设于所述清水箱的侧边，这里的侧边具有较宽的保护范围，即只要两者相邻即可，而并不需要上部或下部平齐。在实际结构中，可以将吸力电机设于所述清水箱的斜上方。
优选的，所述清水箱位于所述污水箱的正上方。即，两者的轴心线基本同线设置。
优选的，所述清水箱和吸力电机均位于所述污水箱的上方。
优选的，所述洗地机主体的骨架主体大致呈S形。
优选的，所述清水箱设于所述骨架主体的正面，所述吸力电机设于所述骨架主体的背面。
优选的，所述骨架主体的正面还设有所述污水箱，所述污水箱位于所述清水箱的下方。
优选的，所述污水箱的侧边设有电池，所述电池设于所述骨架主体的背面。
优选的，所述吸力电机的底面设有提手结构。
优选的，所述地刷内主要设有用于清洗地面的滚筒、用于控制滚筒的滚筒电机、以及喷液装置。
优选的，所述壳体内只有一个滚筒。优选的，所述滚筒位于壳体的前方。
由于上述技术方案运用，本发明与现有技术相比具有下列优点：
1.本发明开发了一种新结构的家用洗地机，通过将吸力电机设于清水箱的侧边，从而避免了吸力电机的高度在设备整体高度上的影响，从而同时兼顾了洗涤水量和设备的整体高度，提高了用户体验，显然具有积极的实际意义；
2.为了配合吸力电机位于清水箱侧边的结构，本发明将洗地机主体的骨 架主体设计为大致呈S形，并将清水箱设于骨架主体的正面，吸力电机设于骨架主体的背面，从而不仅充分利用了空间，而且重心更稳，不容易出现侧翻等意外情况，提高了用户体验；
3.本发明在吸力电机的底面设有提手结构，因而可以用该提手结构提起整个设备，方便搬运，尤其是上下楼，非常好用、便捷；
4.本发明的吸力电机位于清水箱侧边，可以适当拉长风道结构，有助于降噪，相比普通的真空吸尘器，洗地机需要更大的真空度和功率，因此噪音也相对较大，因此，设计降噪结构更符合实际情形，更好地满足客户要求，提高用户体验；
5.本发明的产品结构简单，成本较低，且具有良好的商业化意义，适于推广应用。
