Description
Technical field
The present invention relates to the field of Medical Instruments, more particularly, to a kind of control box of intelligent charge and discharge pneumatic mattress.
Background technology
Sound is the sound wave as caused by object vibration, is to pass through medium（Air or solid, liquid）Propagate and can by people or
The wave phenomenon that animal auditory organ is perceived.Sound is vibrated in the form of ripple（Vibrations）Propagate, can be passed by any material
Broadcast the motion to be formed.
Object is called frequency in the number of the internal vibration of one second, and unit is hertz, alphabetical Hz.The ear of people can be heard
20Hz-----20KHz sound, most sensitive is the sound between 1KHz-----3KHz.
The reflection performance of noise is sound, and every obstruction people normally rest, the sound of study and work, and to people
The 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：<400Hz low frequency is made an uproar
Sound, 400~1000Hz mid-frequency noise and>1000Hz high-frequency noise.
According to People's Republic of China (PRC) GB3096-93《Standard of environmental noise of urban area》, convalescence area, advanced villa quarter,
The region night noise standard value that area of luxurious hotel etc. especially needs peace and quiet should be less than 40dB, to live, based on culture and education office
Region night noise standard value should be less than 45dB.
But currently there are with air pump driving charge and discharge pneumatic mattress work when noise it is larger, influence night peace and quiet
Sleep environment.
Weaken noise mainly to carry out by following 3 kinds of modes：1）Weaken noise at sound source.2）Weaken in route of transmission
Noise.3）Weaken noise at human ear.The comfort level of user would generally be influenceed due to weakening noise at human ear, therefore the present invention is main
Carried out by weakening sound source and cut-out route of transmission two ways.
The content of the invention
It is an object of the present invention to minimize control box in the case where ensureing normal service rating, and in air pump
Noise is reduced during work.
According to object above, present invention firstly provides a kind of control box of intelligent charge and discharge pneumatic mattress, including box body and upper lid,
The first pump, the second pump, the first magnetic valve, second solenoid valve, gas circuit converter and pcb board are disposed with box body, it is described
Box body is provided with sound hole, and described gas circuit converter, which is arranged at box body, one end of sound hole, and the other end is provided with second solenoid valve,

The first Jing Yin box is provided between the first described magnetic valve and second solenoid valve.
The second described pump is provided with the second Jing Yin box close to sound hole end.
Described gas circuit converter is cased with dirt-proof boot.
Soft air pipe phase is used between described the first pump, the second pump, the first magnetic valve, second solenoid valve and gas circuit converter
Even.
Described pcb board is arranged at the top of box body, and adjacent with upper lid.
The bottom of described box body is provided with slipmat.
The first described pump and the second pump use special Jing Yin air pump, and use the exploitation speed of PWM technical controlling pumps.
Wrapped up outside the first described pump and the second pump using vibration-proof silent rubber cushion.
The present invention has advantages below：
Noise reducing when 1. air pump works in machine box
By using Jing Yin air pump（And air pump is fixed in machine box）, the Jing Yin rubber cushion of damping（It is wrapped in air pump surface）, PWM speed
Rate control technology and Jing Yin box（Two ride and buckle relative misalignment in Jing Yin box）, reduce noise during air pump work.
2. reducing vibrations during air pump work, make whole system more stable
Air pump and machine box are isolated by damping silent rubber cushion, and the position of integral member is reduced by structure design, with
Reach the purpose for making whole system more stable.
3. the structure design of densification, reduce machine box body product
Gas circuit structure overall compact, unnecessary structure space is reduced, reduce the volume of control box to greatest extent.Control box
Size is 200.28mm × 144.98mm × 59.00mm.

Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.Unless stated otherwise, the present invention uses
Reagent, apparatus and method be the art routinely reagent, equipment and conventional use of method purchased in market.
A kind of control box of intelligent charge and discharge pneumatic mattress, including box body and upper lid, the first pump, second are disposed with box body
Pump, the first magnetic valve, second solenoid valve, gas circuit converter and pcb board, box body are provided with sound hole, and gas circuit converter is arranged at box
Body has one end of sound hole, and the other end is provided with second solenoid valve, and the first magnetic valve is arranged at gas circuit converter and second solenoid 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 magnetic valve.The
The first Jing Yin box is provided between one magnetic valve and second solenoid valve.Second pump is provided with the second Jing Yin box close to 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 magnetic valve, second solenoid valve and gas circuit converter
It is connected.Pcb board is arranged at the top of box body, and adjacent with upper lid.The bottom of box body is provided with slipmat.
Wherein, the first pump, the second pump are wrapped up using vibration-proof silent rubber cushion, and are fixed on box body by the screw hole on rubber cushion
On.In pump work, vibrations can be weakened by vibration-proof silent rubber cushion, noise during so as to reduce pump work.The characteristics of due to rubber
It is that existing elastomeric state has high glutinous state again, the elasticity of rubber is the phase between rubber molecule as caused by the change of its coiled molecule conformation
Interaction can hinder the motion of strand, show stickiness feature again, so that stress and strain is often in non-equilibrium state.Rubber
The long-chain molecule structure of this curling of glue and intermolecular existing weaker secondary power so that elastomeric material shows uniqueness
Viscoelasticity energy, thus there is good damping, sound insulation and shock-absorbing capacity.
First pump, the second pump use special Jing Yin air pump in itself, reduce noise at sound source.The noise of air pump mainly comes
From 2 aspects：1）Motor produces when doing work.2）Air during pipe friction with producing.Jing Yin air pump is started with from these two aspects, itself
Material uses more excellent Jing Yin sound insulation material, reduces the generation of noise.
Meanwhile system uses the speed of PWM technical controlling pumps, further reduce due to noise caused by motor acting.
PWM, i.e. pulse width modulation, it is that the break-make of inverter circuit switching device is controlled, output end is obtained a series of amplitudes
Equal pulse, sine wave or required waveform are replaced with these pulses.Namely in the half period of output waveform
Multiple pulses are produced, the threshold voltage that waits for making each pulse is sinusoidal waveform, and the output smoothing and low-order harmonic obtained is few.By certain
Rule the width of each pulse is modulated, you can change the size of inverter circuit output voltage, can also change output frequency.
Secondly, the first Jing Yin box, the second Jing Yin box are added in the gas circuit inside control box, is reduced respectively and is being inflated and arranging
Because of noise caused by air velocity and friction during gas.Because the gas flow rate exported in pump is very fast, therefore air can rub with tube wall
Wipe and collide, trigger noise.After Jing Yin box is set in gas circuit, when gas is by Jing Yin box, gas circuit can be undergone and become big from small
The process to diminish again, in the process, the speed of gas molecule are controlled, and the friction and collision with tube wall become soft, because
Therefore this noise can also reduce.
