CN104687856A - Automatic unidirectional ventilation pad - Google Patents

Abstract

The present invention relates to an automatic unidirectional ventilation pad composed of a plurality of identical interconnected box bodies, wherein each box body is provided with a hexagonal prism-shaped framework (1), an air chamber (2), a connecting pipe (3), an intake valve (4), an exhaust valve (5), an air outlet hole (6) and an air inlet hole (7). The automatic unidirectional ventilation pad is characterized in that when the box body is stressed, the framework (1) is deformed, the air chamber (2) is compressed, the exhaust valve (5) is opened, and air is exhausted from the air outlet hole (6); when the air outlet hole (6) is blocked, the air flows to the air outlet hole (6) of the adjacent box body from the connecting pipe (3); when the pressure is reduced or eliminated, the exhaust valve (5) is closed, the framework (1) resets by means of an elastic force, the intake valve (4) is opened, and the air enters the air chamber (2) from the air inlet hole (7). By means of the deformation of the box body and the unidirectional valves in the air chamber, a unidirectional ventilation function is achieved, a plurality of identical structures are interconnected and intercommunicated to form entireties having the same functions and capable of mutually supplementing, the box bodies can be made into different sizes and shapes according to application requirements, and the automatic unidirectional ventilation pad has the advantages of simple structure, high ventilation efficiency, energy saving, environmental protection, and low production and use costs.

Description

Automatic one-way ventilating pad

Technical field

The present invention relates to the mat having and realize ventilation by pressure change, especially form the one-way ventilating function of mat when acting on the change of the pressure on mat.

Technical background

At present, in life, various seat cushion, mattress, back cushion are very common, and its airing function is one of leading indicator of selecting of people in the application process of these mats, the mat that permeability is good in use can give people more comfortable sensation, sit end user, lie, when leaning against on mat, health and mat contact portion temperature can raise, body secretes sweat, and sweat can effectively be discharged by the mat that permeability is good, reaches the object reducing local temperature.Based on this theory, people are trying out different materials is always processed into the mat of different structure to adapt to the demand of people's life, such as adopt mat that the material of natural fabric is processed into have and make full use of natural plant fibre water suction, ventilative performance reaches good result of use, and adopt the various twice-laid mat of modern synthesis to add the gas permeability of mat because of the superior elasticity of artificial fiber, but these materials with fine air permeability are in the circulation being subject to can not being formed when user's health constantly contacts compression effective local gas and ambient gas, and just form the gas circulation of a local, the ventilatory effect of contact site is not very good.In recent years, along with popularizing of family saloon, in car, the standard of environment to gas permeability of relative closure is had higher requirement, market there is various cancellated mat, and in order to increase permeability, more there is various types of electronic ventilation mat, motor driving force is utilized to realize continual ventilation, the ventilation effect of this electronic ventilation mat is equally distributed, which forms impingement area identical with not close contact area ventilation effect, the not close contact area ventilation too much phenomenon of impingement area hypoventilation may be there is, people is made to feel cold and hot uneven, comfort level is poor, sometimes in order to regulate this species diversity, the normal method adopting interruption ventilation, namely ventilatory function is opened and is hocketed with closedown.In addition, the use of this electronic ventilation mat is subject to condition of power supply and limits, and higher production cost, uses the expense such as power consumption, maintenance also very important for a long time.

Summary of the invention

For solving above-mentioned technical deficiency, the invention provides a kind of device of automatic one-way ventilating, this device is connected by multiple polygon small box that is relatively independent and that be interconnected and forms, and the pressure change in use contacting mat forms the one-way circulation of air.The technical scheme that the present invention solves is: a kind of one-way ventilating pad automatically, be formed by connecting by multiple same casing, each casing is provided with hexagon framework (1), air chamber (2), tube connector (3), intake valve (4), air outlet valve (5), venthole (6) and air admission hole (7), it is characterized in that, framework (1) distortion when casing is stressed, air chamber (2) is compressed, air outlet valve (5) is opened, air is discharged from venthole (6), when venthole (6) is blocked, air flows to the venthole (6) of contiguous casing from tube connector (3), when pressure reduces or eliminate, air outlet valve (5) cuts out, framework (1) relies on elastic reaction to resile, intake valve (4) is opened, air enters air chamber (2) by air admission hole (7).

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

The present invention is specifically described by example below in conjunction with accompanying drawing.

Detailed description of the invention

Automatic one-way ventilating pad, be formed by connecting by multiple same casing, each casing is provided with hexagon framework 1, air chamber 2, tube connector 3, intake valve 4, air outlet valve 5, venthole 6 and air admission hole 7, it is characterized in that, when casing is stressed, framework 1 is out of shape, air chamber 2 is compressed, air outlet valve 5 is opened, air is discharged from venthole 6, when venthole 6 is blocked, air flows to the venthole 6 of contiguous casing from tube connector 3, when pressure reduces or eliminate, air outlet valve 5 cuts out, framework 1 relies on elastic reaction to resile, intake valve 4 is opened, air enters air chamber 2 by air admission hole 7.Utilize valve unidirectional in the distortion of casing and air chamber to reach the function of one-way ventilating, multiple identical structure is interconnected and communication, forms the identical entirety that can complement each other again of function, can make different size and shape according to instructions for use.

The present invention has and utilizes the power of user's position chanP to form the compression of air chamber and resilience, realizes the function of one-way ventilating, it has, and structure is simple, ventilation efficiency is high, energy-conserving and environment-protective, making and the advantage such as use cost is cheap.
