Description
Technical field
The present invention relates to the field of Medical Instruments, more particularly, to the control box of a kind of intelligence inflation/deflation mattress.
Background technology
Sound is the sound wave produced by object vibration, be propagated by medium (air or solid, liquid) and can by people or
The wave phenomenon of animal auditory organ institute perception.Sound vibrates (vibrations) with the form of ripple and propagates, and can be passed by any material
Broadcast the motion of formation.
Object is called frequency at the number of times of the internal vibration of a second, and unit is hertz, letter Hz.The ear of people can be heard
The sound of 20Hz-----20KHz, most sensitive is the sound between 1KHz-----3KHz.
The reflection performance of noise is sound, and every obstruction people normally have a rest, the sound of study and work, and to people
Sound to be listened produces the sound of interference, can be referred to as noise.Noise can be divided into by the frequency of sound: < low frequency of 400Hz is made an uproar
The mid-frequency noise of sound, 400～1000Hz and > high-frequency noise of 1000Hz.
According to People's Republic of China (PRC) GB3096-93 " standard of environmental noise of urban area ", convalescence area, senior villa quarter,
The region night noise standard value that district of luxurious hotel etc. needs peace and quiet especially should be less than 40dB, to live, culture and education office
Region night noise standard value should be less than 45dB.
But currently there are the inflation/deflation mattress work driven with air pump time noise relatively big, affect peace and quiet at night
Sleep environment.
Weaken noise mainly to be carried out by following 3 kinds of modes: 1) at sound source, weaken noise.2) weaken in route of transmission
Noise.3) at human ear, noise is weakened.The comfort level of user would generally be affected owing to weakening noise at human ear, therefore the present invention is main
Carry out by weakening sound source and cut-out route of transmission two ways.
Summary of the invention
It is an object of the invention to, box miniaturization will be controlled in the case of ensureing normal service rating, and at air pump
Noise is reduced during work.
According to object above, present invention firstly provides the control box of a kind of intelligence inflation/deflation mattress, including box body and upper cover,
The first pump, the second pump, the first electromagnetic valve, the second electromagnetic valve, gas circuit transducer and pcb board it is disposed with in box body, described
Box body is provided with sound hole, and described gas circuit transducer is arranged at box body one end of sound hole, and the other end is provided with the second electromagnetic valve,

The first quiet box it is provided with between the first described electromagnetic valve and the second electromagnetic valve.
The second described pump is provided with the second quiet box near sound hole end.
Described gas circuit transducer is cased with dirt-proof boot.
Soft air pipe phase is used between described the first pump, the second pump, the first electromagnetic valve, the second electromagnetic valve and gas circuit transducer
Even.
Described pcb board is arranged at the top of box body, and adjacent with upper cover.
The bottom of described box body is provided with slipmat.
The first described pump and the second pump use special quiet air pump, and use the exploitation speed of PWM technical controlling pump.
The first described pump and the second pump outside use vibration-proof silent rubber cushion parcel.
The invention have the advantages that
1. noise reducing when air pump works in machine box
By using quiet air pump (and air pump fix in machine box), the quiet rubber cushion of damping (being wrapped in air pump surface), PWM speed control
Technology processed and quiet box (in quiet box two ride buckle relative misalignment), reduce noise during air pump work.
2. reduce vibrations during air pump work, make whole system more stable
By damping silent rubber cushion isolation air pump and machine box, and the position of integral member is made to reduce, to reach by structure design
Make the purpose that whole system is more stable.
3. the structure design of densification, makes the long-pending reduction of machine box body
Gas circuit structure overall compact, reduces unnecessary structure space, reduces the volume controlling box to greatest extent.Control box size
For 200.28mm × 144.98mm × 59.00mm.

Detailed description of the invention
The present invention is further described below in conjunction with the accompanying drawings with specific embodiment.Unless stated otherwise, the present invention uses
Reagent, equipment and method be the art conventional commercial reagent, equipment and conventional use of method.
A kind of intelligence inflation/deflation mattress control box, including box body and upper cover, be disposed with in box body the first pump, second
Pump, the first electromagnetic valve, the second electromagnetic valve, gas circuit transducer and pcb board, box body is provided with sound hole, and gas circuit transducer is arranged at box
Body has one end of sound hole, and the other end is provided with the second electromagnetic valve, and the first electromagnetic valve is arranged at gas circuit transducer and the second electromagnetic valve
Between, the first pump is arranged at a corner of box body, and the second pump is arranged at the middle part of box body, and arranged side by side with the first electromagnetic valve.The
The first quiet box it is provided with between one electromagnetic valve and the second electromagnetic valve.Second pump is provided with the second quiet box near sound hole end.Gas circuit turns
Parallel operation is cased with dirt-proof boot.Soft air pipe is used between first pump, the second pump, the first electromagnetic valve, the second electromagnetic valve and gas circuit transducer
It is connected.Pcb board is arranged at the top of box body, and adjacent with upper cover.The bottom of box body is provided with slipmat.
Wherein, the first pump, the second pump use vibration-proof silent rubber cushion parcel, and are fixed on box body by the screw hole on rubber cushion
On.When pump work, vibrations can be weakened by vibration-proof silent rubber cushion, thus noise when reducing pump work.Feature due to rubber
Being that existing elastomeric state has again high sticky stage, the elasticity of rubber is to be produced by the change of its coiled molecule conformation, phase between rubber molecule
Interaction can hinder the motion of strand, shows again stickiness feature, so that stress and strain is often in unbalanced state.Rubber
The long-chain molecule structure of this curling of glue and the more weak secondary power of intermolecular existence so that elastomeric material presents uniqueness
Viscoelasticity energy, thus there is good damping, sound insulation and shock-absorbing capacity.
First pump, the second pump itself uses special quiet air pump, reduces noise at sound source.The noise of air pump mainly comes
From 2 aspects: 1) motor acting time produce.2) produce when air and pipe friction.Quiet air pump is started with from these two aspects, itself
Material uses the most excellent quiet sound insulation material, reduces the generation of noise.
Meanwhile, system uses the speed of PWM technical controlling pump, reduces the noise owing to producing when motor does work further.
PWM, i.e. pulse width modulation, be that the break-make to inverter circuit switching device is controlled, make outfan obtain a series of amplitude
Equal pulse, replaces sine wave or required waveform with these pulses.Namely in the half period of output waveform
Producing multiple pulse, the threshold voltage that waits making each pulse is sinusoidal wave form, and the output smoothing and the low-order harmonic that are obtained are few.By certain
Rule the width of each pulse is modulated, the size of inverter circuit output voltage can be changed, it is possible to change output frequency.
Secondly, in controlling the gas circuit within box, add the first quiet box, the second quiet box, reduce respectively inflation and row
Because of air velocity and fricative noise during gas.Owing in pump, the gas flow rate of output is very fast, therefore air can rub with tube wall
Wipe and collision, cause noise.After quiet box is set in gas circuit, when gas is by quiet box, gas circuit can be experienced big from little change
The process diminished again, in the process, the speed of gas molecule is controlled, and friction and collision with tube wall become soft, because of
Therefore this noise also can reduce.
