Description

A multifunctional temperature and humidity controllable massage wheelchair

technical field

The invention relates to the technical field of refrigeration and medical equipment, in particular to a multifunctional massage wheelchair with controllable temperature and humidity.

Background technique

With the continuous acceleration of the aging process of our society, and the increase in the number of people with impaired human body functions due to diseases, accidents, work-related injuries, etc., there are more and more wheelchair users. Since users with limited mobility often spend a long time in wheelchairs, it is necessary to improve the thermal comfort of wheelchairs, especially to solve the problem of hot, sweaty buttocks and backs caused by long-term wheelchair use in summer, and even decubitus problems, as well as problems caused by the amount of exercise of users in winter. The problem of cold extremities due to low, weak, and especially poor blood circulation at the extremities of the body is critical. Therefore, designing a massage wheelchair with high comfort and adjustable temperature and humidity on demand is of great significance for improving the quality of life of users.

At present, some of the existing products of the same type can cool and heat the seat and back cushions of wheelchairs, but these products often only rely on semiconductors to directly cool and heat the seat and back cushions, and the energy efficiency is low and the effect is not obvious. In summer, cooling of the user's head and the front of the body is not considered, and ventilation and dehumidification and warmth of the limbs in winter are ignored; although a small number of products involve ventilation, the design of the cushion structure is unreasonable, and the human body is not considered. The problem of living vents, the ventilation effect is not good. Based on the analysis of the existing technology, it is of great significance to comprehensively improve the functionality of the wheelchair and the thermal comfort of the user.

Pipe network radiation heating and cooling is an energy-saving and high-comfort heating and cooling method. The temperature difference between the hot and cold water supplied and the human body is small, and the cooling and heating are uniform. Etc.

The discomfort of wheelchair users in summer often comes from the wet sweat on the buttocks and back. Only cooling the seat and back cushions is not enough to meet the comfort requirements, so the design of ventilation function is essential. Whether the structure of the cushion and back cushion is reasonable or not determines the ventilation effect, so the design of the structure is also crucial.
