Ventilation mattress

Abstract

A ventilation mattress is constructed to include an outer bag, the outer bag having air vents in a top fabric sheet layer thereof and an air inlet, a flexible tube connected to the air inlet of the outer bag, an electric fan installed in the flexible tube and adapted to draw currents of air into the inside of the outer bag, a fabric stuffing member formed of interwoven spandex fibers and stuffed in the outer bag, a flexible pad provided at the bottom side of the fabric stuffing member, the flexible pad having springy support members connected between top and bottom cover layers thereof for enabling air to circulate through the flexible pad between the air inlet and the air vents at the outer bag.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a mattress and, more particularly, to a ventilation mattress, which uses an electric fan to provide currents of air through air vents in the top layer of the outer covering for ventilation. The ventilation mattress can be made in any of a variety of forms for use as a seat mattress, sofa mattress, or bed mattress. [0003] 2. Description of the Related Art [0004] Straws and bamboo strips are commonly used for making cooling mattresses for the advantage of being highly ventilative. Lying or sitting on a cooling mattress during a hot weather is comfortable at the initial stage. However, a cooling mattress absorbs heat energy from the surrounding and the user's body when in use, its cooling effect is gradually diminished with the time in which the user sits or lies on the cooling mattress. [0005] There are also known seat and bed mattresses formed of strings of ball or block elements. The...

AI Technical Summary

Benefits of technology

[0007] The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the ventilation mattress comprises an outer bag stuffed with a fabric stuffing member for ventilation. According to another aspect of the present invention, the fabric stuffing member is formed of interwoven spandex fibers and having open spaces for circulation of air through the at least one air inlet and the air vents. According to still another aspect of the present invention, a flexible pad is provided at the bottom side of the fabric stuffing member to improved the flexibility and ventilation of the ventilation mattress. According to still another aspect of the present invention, high-performance fans are installed to draw air into the outer bag for circulation. According to still another aspect of the present invention, membrane type pressure switches are provided inside the outer bag and adapted to turn on the high-performance fans when the user sitting on the ventilation mattress, or to turn off the high-performance fans when the user left the ventilation mattress. According to still another aspect of the present invention, electric cooling fans or electric fans with electric heater means may be alternatively used. According to still another aspect of the present invention, semiconductor cooler chips may be used with the high-performance fans.

Problems solved by technology

However, a cooling mattress absorbs heat energy from the surrounding and the user's body when in use, its cooling effect is gradually diminished with the time in which the user sits or lies on the cooling mattress.

However, when sitting or lying on a seat or bed mattress of this design, the user's body will block the open spaces, and the seat or bed mattress becomes hot within a short time.

This design of seat mattress still has drawbacks.

Because currents of air are guided in a particular direction, the ventilation effect is limited.

Further, because the inner layer is a hard member, it is not comfortable to sit on the seat mattress.
