Phase-change temperature-adjusting seat cover

Abstract

The invention discloses a phase- change temperature -adjusting seat cover which comprises a protective cover, a piezoelectric plate, a phase change heat supply device and a power supply device are arranged in the protective cover, the phase change heat supply device comprises a heat supply micropipe, a heat storage micropipe, a liquid supply pipe, a circulating pump, a phase change heat storage layer and an electric heating device, the heat storage micropipe is arranged in the phase change heat storage layer, and the bottom of the heat storage micropipe is connected with the electric heating device. The power supply device comprises a time delay relay, the heat supply micropipe is connected with the heat storage micropipe through a liquid supply pipe, a circulating pump is arranged on the liquid supply pipe, and the piezoelectric plate is used for controlling on-off of the time delay relay. The phase- change temperature -adjusting seat cover is simple and easy to implement, constant-temperature adjustment work of the seat is achieved by transforming an existing seat at low cost, and the thermal comfort degree of the human body on the seat is improved with extremely low energy consumption; and when a person sits on the seat, electric energy is generated by utilizing human body moving energy, at the moment, the piezoelectric plate is equivalent to a human body detection sensor, and the generated electric energy drives the relay to act, so that the circulating pump is driven, and heat supply is realized.

Description

technical field [0001] The invention relates to a seat cover, in particular to a seat cover with phase change temperature regulation. Background technique [0002] With the development of modern society, public transportation plays an important role more and more. The development of urban intercity public transportation can not only promote personnel exchanges, but also facilitate the flow of people. It is also an important way to reduce fossil energy consumption and reduce environmental pollution. As an important part of the public transportation system and an important supporting facility, the operation and comfort of the waiting hall still need to be further improved, especially the seats in the waiting hall. Seats in many stations are in disrepair for a long time, some are made of steel materials, hot and humid in summer, cold in winter, and the comfort level is mixed. However, the waiting hall is often a large space, and the air outlet of the air conditioner is high, ...

AI Technical Summary

Problems solved by technology

The seats at many stations are in disrepair for a long time, and some are made of steel materials. The summer is humid and hot, and the winter is cold.

[0003] The structure of the existing seat cushion is complicated, and an additional temperature sensor is required to identify the actual temperature of the seat cushion, which consumes a lot of heating energy and costs a lot; at the same time, it cannot meet the requirements of seats of different specifications
