Cushion capable of automatically and circularly reducing temperature by liquid

Abstract

The invention discloses a cushion capable of automatically and circularly reducing temperature by liquid, comprising a cushion liquid bag, a cushion, check valves, automatically-sealed connectors, a hose, a heat-preservation bag, an ice bag, a sealing cover, a cooling liquid bag, a fixing belt, a zip fastener and a temperature adjusting valve, wherein an inlet and an outlet of two sides of the cushion liquid bag are forwardly and backwardly connected with two check valves, and are respectively connected with upper and lower inlet and outlet of the cooling liquid bag through the automatically-sealed connectors to form a liquid flowing circuit; and the movement of a human body or operation vibration of a car is used for generating pressure on the cushion liquid bag in the cushion to be circularly cooled by the cushion liquid bag; a power supply is not needed and the cooling cushion can be automatically exchanged with the ice bag in the heat-preservation bag; and the cushion has the advantages of wide application range, simple structure, no noises, no power consumption, safety and reliability, and adjustable temperature, and can solve the problems of lowering the temperature of the cushion of homes, office fields and cars in summer under a high-temperature environment.

Description

technical field [0001] The invention relates to a liquid cushion, in particular to a cushion with automatic circulation and cooling of liquid, belonging to daily necessities. Background technique [0002] In the hot summer, people sit on office chairs for a long time, which makes people feel hot and dry. Especially in summer when the car is parked, the temperature of the seat cushion is higher. Even if the air conditioner is turned on to the maximum, it will take a long time to cool down slightly, but the seat cushion However, it is still very hot, and the back and buttocks of the body are in contact with it for a long time, which often causes sweating on the buttocks. The sticking of the skin for a long time will cause skin diseases and hemorrhoids on the human body. Therefore, people have designed fans Seat cushions, semiconductor refrigeration cushions, and liquid water-cooled cushions are beneficial to relieve the pressure and fatigue on the buttocks of sedentary workers...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the above problems, and provides a cushion with simple structure, no noise, no liquid circulation pump, and no power consumption, which can automatically circulate and cool the liquid, which solves the problem of cooling the cushion in the high-temperature environment of homes, offices and cars in summer. The cushion includes: a cushion liquid bag, a cushion, a one-way valve, a self-sealing joint, a hose, a thermal insulation bag, an ice bag, a sealing cover, a cooling liquid bag, a fixing belt, a zipper, and a temperature regulating valve, and is characterized in that: the cushion The inlet and outlet connections on both sides of the liquid bag are connected to the two one-way valves in positive and negative directions, respectively connected to the self-sealing joints through hoses to connect the upper and lower inlet and outlet connections of the cooling liquid bag to form a liquid flow circuit. The pressure of the bag makes the internal liquid move to the cooling liquid bag in one direction through the one-way valve and then return to the cushion liquid bag to generate an automatic cycle. The ice bag contacts the cooling liquid bag to cool the internal liquid and conducts it repeatedly to cool the seat cushion.
