Description

Technical Field

[0001] The invention relates to the technical field of living facilities, and in particular to a sitting simulated human hand back rubbing device for assisting elderly people in bathing. Background Art

[0002] Bathing is an indispensable daily health and hygiene activity for everyone. With the improvement of people's living standards, bathing at home has become a common phenomenon. However, due to the limitation of the human body's own structure, the back of the human body cannot be effectively cleaned, especially for the elderly group, whose physical functions decline and joint movements are inflexible, bathing has become a major problem. There are fewer machines with back-rubbing function on the market at present. The mechanical structure of the existing back-rubbing machine is relatively simple, and the degree of automation is low. For example, the automatic back-rubbing machine uses the simple rotation and single movement of the scrubbing head as the main back-rubbing method, which cannot simulate the back-rubbing method of human hands, and the group use sense is poor. There are also a few back-rubbing machines that have a more comfortable back-rubbing method, but the machine occupies too much space and is expensive, such as the self-service back-rubbing machine that can be sat on, which is not suitable for home use by ordinary families. And these back-rubbing machines are not designed for specific groups of people, and have universality. There is no corresponding design for the use needs of the elderly group, and the safety and comfort of the elderly group cannot be guaranteed. Summary of the invention
