Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples:
Fig. 1 is connecting structure for electrical equipment schematic diagram of the invention；
Fig. 2 is the structure chart of solenoid valve of the present invention；
Fig. 3 is the line A-A cross-sectional view of Fig. 2.
Specific embodiment
Referring to figs. 1 to Fig. 3, novel external counterpulsation device, including calf bladder, thigh air bag and buttocks air bag, above-mentioned air bag
It is connected to gas tank and air compressor by solenoid valve, gas tank is communicated with electric pressure-regulating valve and muffler, and above-mentioned air bag is also logical
It crosses solenoid valve to be connected to negative-pressure cup, negative-pressure cup is connected to air compressor.When the blood pressure of people is got higher, electric pressure-regulating valve will be beaten
It opens, the external world is discharged by muffler in the gas in gas tank, to reduce the gas of calf bladder, thigh air bag and buttocks air bag
Pressure, to guarantee that the blood circulation of human body is maintained at a comfortable area operation.On the contrary, when the blood pressure of human body is lower, electricity
Dynamic pressure regulator valve may turn off valve, and air compressor is allowed constantly to inflate to gas tank, increase calf bladder, thigh air bag and buttocks
The air pressure of air bag guarantees that the blood circulation of human body is maintained at a comfortable area operation.It is improved using this external counterpulsation unit
During body, the revolving speed of the air compressor is to maintain constant, the gas of calf bladder, thigh air bag and buttocks air bag
The variation of pressure is mainly controlled by electric pressure-regulating valve；It is connected to moreover, because air bag also passes through solenoid valve with negative-pressure cup, negative pressure
Tank is connected to air compressor, calf bladder, thigh air bag and buttocks air bag can respectively with air compressor, gas tank, electricity
Magnet valve and negative-pressure cup form the closed-loop system of respective gas circulation, guarantee that air humidity, particle in the circulatory system etc. is kept
Stablize, be effectively ensured the service life of air compressor and its motor, the utility model external counterpulsation unit have preferable stability and
Longer service life.In addition, connecting negative-pressure cup, calf bladder, thigh air bag or buttocks gas when solenoid valve closes gas tank
When capsule, air in calf bladder, thigh air bag or buttocks air bag can reduce pressure when the outside blood supply of heart by rapid deflation
Power guarantees blood good circulation in human body.
Since the negative-pressure cup is communicated with aeration valve, when the air in the closed-loop system of gas circulation is very few, aeration valve
It will operate, extraneous air is squeezed into negative-pressure cup, supplements air, guarantee that this external counterpulsation apparatus works normally.
The gas that air compressor types it out in order to prevent damages other accessories or makes institute's calf bladder, thigh air bag and stern
The temperature of portion's air bag is excessively high and keeps human body sensory uncomfortable, cooler is communicated between the gas tank and air compressor, air
Through subcooler just enter gas tank after coming out from compressor.
Wherein, the solenoid valve is integrated design, the side connection of valve body 1 there are three respectively with calf bladder, thigh gas
What capsule was connected to buttocks air bag carrys out air returning pipe joint 2, is equipped with three inside valve body 1 and carrys out 3,4 and of inlet channel of return gas channel
One outlet passageway 5, inlet channel 4 and outlet passageway 5 are connected to three and carry out return gas channel 3, and three are carried out return gas channel 3 respectively and respectively
From come air returning pipe joint 2 connect, inlet channel 4 and outlet passageway 5 are respectively communicated with inlet suction port 6 and air outlet adapter 7, in air inlet
Channel 4 and three carry out the connectivity part 13 of return gas channel 3 and carry out the connectivity part 13 of return gas channel 3 in outlet passageway 5 and three
Equipped with the piston 8 for blocking its gas circuit, one end of piston 8 is pierced by valve body 1 and is mounted in valve core housing 9, and 9 periphery of valve core housing set is wired
Ring framework 10 and electromagnetic coil 11, coil rack 10 and electromagnetic coil 11 are fixed on valve body 1, are pacified between piston 8 and valve core housing 9
Spring 12 equipped with processing compressive state.Carry out 3, inlet channels 4 of return gas channel since valve inner of the present invention is equipped with three
With an outlet passageway 5, inlet channel 4 is connected to three with outlet passageway 5 and carrys out return gas channel 3, and it is external that this valve body is installed to this
When on counterpulsation device, as long as connecting an air inlet pipe and an escape pipe in inlet suction port and air outlet adapter respectively.Reduction connects
The number on siphunculus road facilitates installation.In addition, the present invention, which concentrates several separated valve bodies, is designed as a valve body, on valve body
All parts are all installed concentratedly on a valve body, so that the characteristics of compact layout of entire valve is orderly, globality is preferable.
When supplying to air bag, the piston at outlet passageway is in close state under the force of a spring, in inlet channel
The piston at place is opened；Otherwise opposite.Come the top of return gas channel 3 since the inlet channel 4 is located at, outlet passageway 5, which is located at, to be come
The end of return gas channel 3.When air bag needs to lose heart, the air by carrying out return gas channel 3 will directly be taken out from outlet passageway 5
It walks, reduces the turning position that air passes through, reduce resistance, make the discouraged more rapidly more thorough of air bag, guarantee the qi of chong channel ascending adversely of air bag and put
Gas is close to the case where human body variation.
In addition, the connectivity part 13 is fixed with valve port bushing 14, one end of piston 8 can be tightly connected with valve port bushing 14,
There is valve port bushing 14, the scope of activities of piston 8 can be efficiently controlled in less range, and guarantee opens or closes air flue
Response react in time.And the other end of piston 8 is in truncated cone, and top is equipped with micelle 15, may be reduced by this way
Top land contacts with valve core housing and generates noise, extends the service life of valve body.Also exist, in the piston end of truncated cone
There are gap 16 between 9 inner wall of portion and valve core housing, gap 16 can accommodate certain air, prevent air from spreading and influencing not in time
The activity of piston.
For the ease of processing, the valve body 1 can be divided for air inlet valve body 17 and outlet valve body 18, air inlet valve body 17 and outlet
Valve body 18 is fixed together by connector.In addition, air inlet valve body 17 is designed to be higher than outlet valve body 18, design can in this way
Guarantee that inlet channel 4 is located at the top for carrying out return gas channel 3, outlet passageway 5 is located at the end for carrying out return gas channel 3, convenient for air-flow
Circulation.For the generation for preventing gas leakage, sealing ring 19 can be equipped in the junction 13 for carrying out return gas channel.Besides for convenience
This valve body is connect with extraneous component, and the position 20 connecting with the external world is located at the bottom of valve body.
It being mounted on to the part secure on valve body top on valve body 1 in order to prevent, the top of the valve body 1 is equipped with groove 21,
9 lower part of valve core housing is equipped with the bulge loop 22 to match with groove 21, and the groove 21 on bulge loop 22 and valve body is tightly connected.
In addition, the calf bladder, thigh air bag and buttocks air bag are communicated with unloading valve, when the air pressure of human body sensory air bag
It is excessively high, but the present apparatus again without adjusting to its comfortable degree when, manpower can directly press the button of unloading valve, allow unloading valve
The air of calf bladder, thigh air bag or buttocks air bag is released, air pressure is reduced.
In short, the technical solution for being equal or deteriorating with the present invention also belongs to this present invention is not limited to the above embodiments
The protection scope of invention.
