The two micro air pumps 1 are connected with the electromagnetic valve through a three-way structure.
The manufacturing method comprises the following steps:
a square shell is manufactured, and a micro air pump, two-position three-way valves, a three-way joint, a display screen, a buzzer, a connecting air pipe and the like are prepared respectively.
An air outlet end 6 of the micro air pump is connected with a first path of a membrane head of a first electromagnetic valve 4, an air suction end 7 of the micro air pump 1 is connected with a first path of a membrane head of a second electromagnetic valve 2, a second path of the membrane head of the first electromagnetic valve 4 and a second path of the membrane head of the second electromagnetic valve 2 pass through a three-way joint 3, and finally the three-way joint 3 is connected to an air pipe on the hand rehabilitation training glove.
The specific working principle is as follows:
when the pneumatic device inflates the trachea of the hand rehabilitation training glove, the glove realizes bending and shaking hands, when the miniature air pump operates, the first electromagnetic valve is electrified, the first path and the second path of the first electromagnetic valve are communicated, and the third path is different from the first path and the second path; the second electromagnetic valve is powered off, the first path of the second electromagnetic valve is communicated with the third path, and the second path of the second electromagnetic valve is not communicated with the first path and the third path; the air outlet end 6 of the micro air pump discharges air to enter a first path of the first electromagnetic valve membrane head, and then enters the air pipe of the hand rehabilitation training glove through a second path after passing through the membrane head; because the first path and the second path of the membrane head of the second electromagnetic valve 2 are different, the first path of the second electromagnetic valve is communicated with the third path, the air is sucked from the third path, and then the air enters the air suction end 7 of the micro air pump.
When the pneumatic device deflates the trachea of the hand rehabilitation training glove, the glove realizes straightening action, the first electromagnetic valve is powered off, the first path of the first electromagnetic valve is communicated with the third path, and the second path of the first electromagnetic valve is not communicated with the first path and the third path; the second electromagnetic valve is electrified, the first path and the second path of the second electromagnetic valve are communicated, and the third path and the first path and the second path are not communicated;
the air outlet end 6 of the micro air pump discharges air and enters a first path of the membrane head of the first electromagnetic valve, and a second path of the micro air pump is communicated with a third path of the electromagnetic valve to discharge air; as the first path and the second path of the membrane head of the second electromagnetic valve 2 are communicated, and the third path and the first path and the second path are not communicated, the air suction end 7 of the electromagnetic valve starts to suck air, and the air in the trachea of the hand rehabilitation training glove is sucked out.
The power-on and power-off processes or programs of the electromagnetic valves are burnt into the MCU singlechip, the MCU singlechip is respectively connected with the micro air pump, the first electromagnetic valve driving circuit, the first electromagnetic valve, the second electromagnetic valve driving circuit and the second electromagnetic valve, and the display screen, the buzzer, the control keys and the indicator lamp are connected with the MCU singlechip in a plug-in mode to realize the circuit principle.
