When the plastic film is tightly attached to the inner wall of the negative pressure groove, the liquid collecting groove is formed, the piston body moves to the lower limit position in the cylinder body, and the air pressure in the air inlet pipe of the air pump is a first air pressure value when the urine in the liquid collecting groove is completely extracted; when the air pressure sensor monitors that the air pressure reaches a first air pressure value, the controller controls the motor to rotate reversely, the motor drives the driving gear to rotate, and the second gear is in transmission connection with the driving belt at the moment, so that the barrel body placing seat drives the liquid suction barrel to move towards the upper part of the shell.
When the cylinder placing seat starts to move from the liquid suction positioning groove to the upper part of the shell, the cylinder is separated from the lower end face of the liquid suction positioning groove, and outside air enters the piston cylinder through the air suction hole of the liquid suction positioning groove under the action of the air pump, so that the reversing push rod is kept at the upper limit position.
After the motor rotates reversely for a specified number of turns, the liquid suction cylinder moves to the upper part of the shell, and the patient can take away the liquid suction cylinder.
Then the air pump stop work, the gaseous process side gas outlet of piston cylinder flows, and the switching-over push rod moves down to below extreme position gradually under the effect of extension spring, and the appointed number of turns is rotated to the motor forward simultaneously for the collecting tank that is located the negative pressure inslot moves gradually to the center of bedpan, finally resumes to initial condition, and the next patient of being convenient for uses.
The air pump is controlled to work, so that the liquid collecting tank can be punctured by the liquid suction barrel before liquid suction is carried out, urine can be collected conveniently, and meanwhile, the air pump can pump air in the negative pressure tank, so that a new liquid collecting tank is formed by the plastic film.
The plastic film can be driven to move by controlling the motor to rotate forwards, and the liquid suction cylinder can be driven to move by controlling the motor to rotate backwards, so that liquid can be sucked by the liquid suction cylinder conveniently and the liquid suction cylinder can be taken away by a user.
When the air pump is out of work, the reversing push rod is located at the limit position below, the motor rotates reversely at the moment, the liquid suction cylinder moves towards the shell, the liquid suction cylinder is convenient to move to the lower portion of the liquid collecting tank, when the air pump works, the air pump drives the reversing push rod to be located at the limit position above, the motor rotates reversely at the moment, the liquid suction cylinder moves towards the outer side of the shell, and a patient can take the liquid suction cylinder conveniently.
