Description

The automatic health promoting pillow of cervical vertebra

This utility model relates to a kind of pillow, particularly can regulate the pillow of height according to the different sleeping positions of human body automatically.

Requirement according to body biomechanics, different sleeping positions, to resting the head on high requirement is different, general side is slept than sleeping on one's back to about the high 5cm of medicated pillow requirement, and the people is when sleep, face upward, two kinds of sleeping positions of side hocket, so have only pillow high energy with the sleeping position automatic and adjustable, just can meet the demands, guarantee the safety of cervical vertebra, otherwise can cause the generation of cervical spondylosis, present existing similar health promoting pillow is as patent announcement number: CN2049894, though also be according to the different sleeping positions of human body, regulate the height of pneumatic die cushion by two mechanically controlled switches that are installed on the pneumatic die cushion limit, thereby reach the purpose that changes the pillow height.But there is following defective in it: because the touch switch of this kind health promoting pillow is mounted on the pneumatic die cushion, whether shake-up by shoulder reflects sleeping position, people are when sleep, if shoulder leaves medicated pillow a little, even and the not touch switch of sleeping on one's back also, if increase the touch switch arm, moving all of horizontal exhibition of arm and cotton-wadded quilt might touch switch when then side was slept, moreover, adopt mechanically controlled switch to also have sensitive inadequately, the reliable shortcoming of action.

The purpose of this utility model is to provide a kind of health promoting pillow that can adjust height of pillow core accurately, reliably according to the variation of human body sleeping position automatically.

This utility model is achieved in that health promoting pillow comprises inflation pillow core, source of the gas, check valve and air bleeding valve, be characterized in: source of the gas is an air pump, the inflation pillow core links to each other with air bleeding valve with air pump by trachea, check valve is connected between air pump and the inflation pillow core, the respectively controlled circuit control of the work of air pump and air bleeding valve, control circuit is connected to pick off, and pick off is made by one group of conductive plastics switch or one group of conductive rubber switch, puts in bed the people following position of shoulder, back of lying down.

Control circuit inserts operational amplifier from end of oppisite phase after comprising one group of resistance parallel connection that links to each other with pick off, constitute an adder, adder output inserts the comparator end of oppisite phase, the reference voltage of comparator inserts it by two resistance series connection backs and holds in the same way, comparator output terminal one tunnel is through a resistance access power amplifier base stage, the colelctor electrode cut-in relay adhesive end of power amplifier, connect with the power supply of air bleeding valve in the contact of relay, thus the work of relay control air bleeding valve; The base stage of another power amplifier is inserted on another road through the RC parallel circuit, its colelctor electrode connects the intervalometer input, its outfan inserts the base stage of another power amplifier again through a resistance, the colelctor electrode of power amplifier inserts the adhesive end of another relay, connect with the power supply of air pump in the contact of relay, by the work of this relay control air pump.Control circuit and air pump, check valve and air bleeding valve can be placed on a following arbitrary position.

The inflation pillow core directly is used as medicated pillow after can mixing pillowcase, also can be placed on below the common pillow.

After different sleeping position information were delivered to control circuit and handled by pick off, control circuit was by the work of two relays control air pumps and air bleeding valve, thereby the inflation pillow core is filled, exit, reached the purpose of adjustment height of pillow core.

This utility model has following advantage:

1. because pick off is to put in bed the people following position of shoulder, back of lying down, so it more can reflect the variation of human body sleeping position accurately, reliably than any existing controlling organization that directly is contained on the pillow core.

2. control circuit, air pump and air valve all are placed on bed down, do not have electric wire, hard thing on the bed, have safety, comfortable characteristics.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described.

Fig. 1 is the location diagram of health promoting pillow and bed.

Fig. 2 is the control circuit schematic diagram.

Pick off 3 is by one group of ultrafine conductive plastics K switch _1-n, be contained at interval in the sack traverse people above position of the following waist of shoulder, back of lying down in bed about 5cm with each.This group conductive plastics K switch _1-nOne end links to each other with the reference battery negative pole, and the other end is respectively by one group of resistance R _1-nOperational amplifier IC is inserted from end of oppisite phase in back in parallel, the outfan of operational amplifier IC inserts the inverting input of comparator A, the reference voltage of A inserts its positive input after connecting with R4 by adjustable resistance Rx, comparator A outfan is leaded up to R2 and is received the base stage of power amplifier T2, the colelctor electrode of T2 links to each other with relay J 2 adhesive ends, and the power supply of the contact of J2 and air bleeding valve 7 is in series; The base stage of power amplifier T1 is received through the RC parallel circuit in another road, and the colelctor electrode of T1 is received the input of 555 intervalometers, and 555 outfans link to each other with power amplifier J3 base stage through resistance R 3, and the colelctor electrode of T3 links to each other with the adhesive end of relay J 1.The power supply of the contact of J1 and air pump 5 is in series.Air pump 5 joins with check valve 4, inflation pillow core 2 successively by trachea 8, and air bleeding valve 7 also is to join by trachea 8 and inflation pillow core 2.Inflation pillow core 2 is placed on the below of common pillow core 1.The power supply of entire circuit and air pump, air valve is provided behind rectification, filtering, seamless by civil power.

Its operation principle is:

When the people sleeps on one's back, it is many that pick off 3 is pressed the anastomosing switch number in back by human body, the output voltage of operational amplifier IC is proportional to the switch number that is switched on, and after comparator A and its reference voltage compare, is output as low level, at this moment, power amplifier T2 ends, and relay J 2 outages are open-minded by the air bleeding valve 7 of J2 control, gas is discharged from the inflation pillow core 2, and pillow is high to descend.When people's side was slept, it was few to be pressed the anastomosing switch number in back by human body, and operational amplifier IC output voltage is low, and comparator A is output as high level, and this moment, relay J 2 was charged, the T2 conducting, and air bleeding valve 7 turn-offs.On the other hand, 555 intervalometer work, and the pulse of exporting a certain width make the T3 conducting, and J1 is charged, stop after the corresponding time of air pump 5 qi of chong channel ascending adversely that controlled by J1, and this moment, check valve 4 was blocked trachea automatically, prevented gas leak, and pillow is high to rise.
