Specific embodiment
Embodiment：
The utility model content is further described with reference to the accompanying drawings and examples, but is not to the utility model
Restriction.
The present embodiment combination Fig. 1, Fig. 2 and 7 come illustrate a kind of executing agency of pressure test device include air cushion 2 respectively with
Air intake valve and outlet valve connect, and the intake valve 3 connects there are four tracheole 7, and the connection of direct and air cushion 2, it is responsible for defeated
Enter gas；It is connected between wherein two tracheoles 7 with a conduction pipe, its purpose is to accelerate feed rate.The tracheole 7
Two of which piston when non-aerating is sealing to tracheole 7, convenient for preventing gas leakage.In the intake valve 3 there are one installations
Pressure-detecting device, and in piston base dress, there are one the suitable springs of elastic force, when air pump fills 4 gas, 4 gas compression of air pump
Piston, spring are compressed, and tracheae is connected at this time, and air cushion 2 is inflated, and sensor has set an atmospheric pressure value at this time, when in air cushion 2
When air pressure reaches this pressure value, air pump 4 receives the signal that sensor transmits, and so as to stop supplying, spring restores original length
Degree, piston seal air inlet pipe 8, and air inlet finishes.For air outlet valve 1, exhaust pipe 5 is also provided with pressure-detecting device, works as air cushion
When interior air pressure is more than the atmospheric pressure value of setting, by the pressure detecting of sensor, sensing electric current, control outlet valve piston fortune are generated
Dynamic, spring is compressed, and gas passes through 5 discharge part gas of exhaust pipe, after the pressure values of air cushion 2 reach setting value, electricity
Source is closed, and piston restores original position, prevents 2 gas leakage of air cushion under the action of the spring.In short, in the executing agency of the present invention
One charge valve and an air outlet valve between the gas-guide tube of air pump 4 and air cushion 2 are set respectively, realized when air pressure is more than setting
Atmospheric pressure value when, air outlet valve deflate or when air pressure be less than setting atmospheric pressure value when, intake valve is inflated so that the air cushion course of work reaches
To a dynamic equilibrium.
This example combines a kind of Keyboard Control parts for the air-cushion device for jumping trampoline of Fig. 4 and further illustrates：The keyboard control
System is using free-standing button, respectively in air pump switch, intake valve and the respectively setting one of outlet threshold switch.It is opened when pressing air pump 4
It closes, electric motor starting, air cushion 2 starts to inflate, and the spring in intake valve 3 is by air pressure at this time, constantly by feedback signal back to gas
Press detection device.
A. when reaching preset atmospheric pressure value, at this point, air pump 4, which receives, stops air inlet signal, power supply is automatically closed, air pump 4
It is stopped,
B. it when needing to change the air pressure preset value of air cushion, presses air pump 4 and switchs, when air pressure is to be up to previous preset
During value, wherein intake valve switch are pressed, air pump 4 works on, and when reaching the atmospheric pressure value for wanting reset, closes inlet open
It closes, air pump 4 is stopped.
C. when the air pressure of air cushion is more than preset value, outlet threshold switch is pressed at this time, air outlet valve 1 is started to work, and piston delays
Slow movement, releases portion gas, and at this moment the pressure test device of air outlet valve 1 detects air pressure change, when air cushion reaches preset value
When, pressure test device detects the signal, feeds back to keyboard circuit, and air outlet valve 1 is automatically closed, and piston returns to original position, stops
Outlet.
This example illustrates a kind of total control circuit for the pressure test device for jumping trampoline, the master control with reference to Fig. 1 and 6
Circuit includes keyboard circuit, air pressure detection circuit, LCD liquid crystal display circuits.The circuit is by mainly by AT89C52 singlechip groups
Into, be entire control circuit brain.The microcontroller P2.0 connects No. 21 contacts, switchs and is keyed with air pump 4, directly controls gas
Switch pump；The microcontroller P2.1 connects No. 22 contacts, switchs and connects with intake valve 3, controls air inlet, changes air pressure preset value control
System needs artificially to control to change the preset value of air pressure；The microcontroller P2.2 connects No. 23 contacts, is directly switched with air outlet valve 1
Connection controls air cushion outlet, changes air pressure in air cushion 2.When air pressure is more than the correction amount of preset value in air cushion 2, pass through control
Air outlet valve 1 switchs, thus it is possible to vary the excessive situation of 2 air pressure of air cushion makes air pressure in air cushion 2 reach the correction amount range of preset value
The artificial control of interior and needs；Followed by air pressure detection circuit, by the detection to air pressure in air cushion 2, feedback information is passed
Air pressure display circuit is sent to, the atmospheric pressure value shown in table in air cushion 2 is shown in air pressure, in this way, people can be allowed more intuitively to know
Air pressure in road air cushion.The air pressure shows one air pressure display circuit of connection in table, and air pressure detection circuit can be fed back
Information is handled, and then shows atmospheric pressure value.
Illustrate a kind of control flow chart for the pressure test device for jumping trampoline with reference to Fig. 4.After its operation principle is switched on
Using button preset pressure value, when the pressure detected is less than preset value, microcontroller sends out signal, drives air pump motor work
Make, pressure is made to reach preset value.When pressure is more than preset value, air pump motor disconnects, and stops inflating, and air outlet valve 1 starts
It deflates.Idiographic flow is as follows：
A. general correction value is set, more than 4 action of air pump makes mattress actual pressure value close to required pressure values
B. we can first preset a correction amount Z when the pressure by mattress is needed to be charged to X.
C. judge when air pump motor is opened, the pressure values Y that pressure sensor detects and the real pressure values of bed body
Difference.
D. motor inflation is then turned on, judges pressure values Y always in the process（This atmospheric pressure value is influenced by air pump not equal to bed
Body actual value）.
E. as pressure values Y>Air pump stops inflation during=X+Z, and sensor detection bed body actual value judges whether it reaches and thinks
The pressure values X to be charged to.If not provided, continue to inflate plus correction amount Z.Work as Y>Stop inflating and judging bed body air pressure during=X+Y
Actual value.
F. bed body air pressure actual value is run up to repeatedly close to required mattress pressure, and air pump is out of service at this time, inflation
Terminate, when air cushion after a period of use, air pressure will necessarily change, and pressure sensor starts feedback signal transmission to gas at this time
Pump 4, air pump 4 works.
Above-described the utility model embodiment, does not form the restriction to scope of protection of the utility model.It is any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
