Abstract

A pressure-sensitive wind cooled mat used under existing cool mat, mattress, or cushion is composed of wind mat and miniature blower. Said wind mat is composed of wind trunk connected to said miniature blower and wind branch tubes connected with wind trank and with air outlets at intervals. Said air outlet is characterized by that its size varies with the pressure applied to it.

Description

Pressure-sensitive wind-cooled mattress

Technical field

The present invention relates to a kind of cooling wind pad, relate in particular to a kind of pressure-sensitive wind-cooled mattress that can regulate wind-force by the pressure sensitivity power.

Background technology

In hot summer, people had such experience, were not having the room sleep of air-conditioning, and the contact site of health and mattress (summer sleeping mat) is dripping through regular meeting's profuse sweating, forces us constantly to stand up, and has difficulty in going to sleep, even there have electric fan to blow to be often also of no avail.This be since the contact site heat radiation of health and mattress freely due to.Many thus inventors have expected being used to the method that the gentle breeze under mattress dispels the heat, as: 89212550, patents such as 88216124,95215302 all have extraordinary thinking and design, but there is weak point in design in they, mainly show the following aspects:

Therefore 1, owing to all be distributed with air outlet on the whole wind pad, whether the someone lies or the place sat all can air-out, and this air-out great majority are to have slatterned.

2, to the design of air outlet direction on the airduct in the wind pad, often air outlet is designed to vertically upward, thereby, can causes air-out not smooth, influence radiating effect because top summer sleeping mat or mattress directly stops up air outlet.

3, electric fan power is non-adjustable in the design in the past, like this under the situation of the degree varies of weather sweltering heat, and can only be with single air quantity.When weather is too warm, deficiency in draught, when weather was not too hot, air quantity was bigger than normal again.

4, design in the past considers to owe few to the variation of the ventilating opening size on the airduct, aspects such as spacing between the ventilating opening.The effect that this has directly influenced heat radiation, design bad can occur from the near part wind of blast main greatly, from blast main slightly far be the very little even calm phenomenon of wind.

Summary of the invention

The object of the present invention is to provide a kind of pressure-sensitive wind-cooled mattress, this wind-cooled mattress only position on the people couches or is sitting in is just understood air-out, and couch or the weight of sitting big more, its air output is also big more, the summer sleeping mat that its air outlet can not be laid down on it stops up, also be not easy to enter dust, air-out is unimpeded, good heat dissipation effect.

A kind of pressure-sensitive wind-cooled mattress provided by the invention, mainly form by the electric fan of a wind pad and an adjustable power, this wind pad is divided into a blast main and a plurality of minutes airducts again, all adopt material with certain flexible intensity, as the square long column body of hollow that polyethylene or polypropylene are made, the both ends of the surface of blast main are closed state, and one offers an air inlet on the rectangular side, be connected with electric fan, have several air outlets on another rectangular side; Each minute, an end face of airduct was a closed state, and the other end is an air inlet, was connected with the air outlet of blast main, and the wind-force of electric fan is delivered in each minute airduct via blast main.Each minute airduct a rectangular side on the compartment of terrain offer the air outlet crack, the size in each crack and the method to set up of spacing are near more apart from this blast main air inlet, its crack is more little, spacing is big more.

The specific embodiment

The wind pad of present embodiment is rectangle, and is slightly less than bed surface size (single, double people's bed is similar), is example with the single bed here, and its organigram as shown in Figure 1.The present invention can adopt polyethylene or polypropylene etc. to have the material of certain elasticity and intensity, and present embodiment is that example is illustrated with the polyethylene.Blast main 4 and the branch airduct 1 made with polythene material are the square long column body of hollow, the two ends of blast main 4 are closed state, offering an air inlet 5 on the one rectangular side links to each other with the electric fan (not shown), wind is sent in the blast main 4, have some air outlets and divide airducts 1 to be communicated with on the blast main 4 with on being provided with corresponding another side, air inlet side with all, wind-force in the blast main 4 can be dispersed in each minute airduct 1, each minute, airduct 1 the other end was closed state, the compartment of terrain offers air outlet crack 6 on each minute airduct 1 the rectangular side, this crack 6 (as top when only spreading one deck summer sleeping mat) under not having the very little situation of pressurized or pressurized is sealing, when the pressure 7 of pressurized acquires a certain degree (as taking when crouching), open in crack 6, wait to remove behind the pressure because flexible effect crack and seal again, as shown in Figure 2.Being set to of the size in each crack and spacing is near more apart from blast main 4, its crack 6 is more little, spacing is big more, and She Ji purpose is when on the wind pad equably during load-bearing like this, can be identical or approaching in the air output size from blast main 4 place far away and nearer its each air outlet crack 6, place.

Fig. 2 A shows that the air outlet crack 6 on the branch airduct 1 is in closed state when dividing an airduct 1 not to be under pressure or pressure when very little; Fig. 2 B shows when being subjected to certain pressure, divides the air outlet crack 6 on the airduct 1 to open, and the pressure that is subjected to is big more, and air outlet is also big more.This has just guaranteed that only air-out is just understood at the position on the people couches or is sitting in, and couch or the weight of sitting big more, its air output is also big more.Couch or the position sat can air-out nobody.It is best that air-cooled like this efficient can reach, and can drive with very low power electric fan.

For environmental protection and health, the airduct of blast main, branch airduct and air inlet has all used certain intensity and flexible polyethylene or polypropylene material.Spacing is 1 centimetre between each minute airduct 1, all each minute airduct 1 usefulness nylon wire 2 form nettedly, reinforce limit 3 with adding with plastic cement around the wind pad simultaneously, so just guaranteed the solid and durable of wind pad.

In order to guarantee that the air outlet crack 6 on the branch airduct 1 do not stopped up by the summer sleeping mat above it or mattress, the direction of its air outlet is a level, and for ease of making, the air outlet direction is unified facing one direction.Nobody lie or the situation of sitting under, dividing the blast in the airduct 1 is uniformly, when this pressure greatly to a certain degree the time, all air outlets can be suppressed and hold certain size, the pressure in the airduct will reduce, thereby guarantees the phenomenon that the wind pad can not occur breaking.Then the wind pad is connected with electric fan, the power of electric fan is unsuitable excessive, be controlled in the 10-50 watt of scope, and adjustable power, usually can from the wind pad, blow out cool breeze slowly with less power, the gentle breeze of Chan Shenging can not produce uncomfortable sensation to human body like this, adds that for ease of the power supply place that is controlled at electric fan a switch gets final product.
