Working principle:
when the equipment is started, the motor assembly 8 operates, suction force is generated at the opening part of the suction port cover plate 2, liquid enters the water-gas separation assembly 1 from the water-gas separation water inlet 106, at the moment, the liquid enters the water tank assembly 9 through the water-gas separation water outlet 105 due to the gravity of the liquid, and meanwhile, gas enters the air duct structure assembly 5 from the suspended air inlet 103; when the amount of liquid in the water tank assembly 9 reaches a certain amount, the water sensing device 104 contacts the certain amount of liquid, and the motor assembly 8 stops running.
As shown in fig. 3 to 5, when the user vertically picks up the machine, the liquid in the water tank assembly 9 flows back into the water-air separation assembly 1 through the water-air separation outlet 105, and the suspended air inlet 103 is installed, so that the liquid cannot enter the air duct structure assembly 5 when the liquid level does not submerge the suspended air inlet 103, and if the inclination angle is increased, the liquid can be isolated, and the liquid cannot directly flow into the air duct structure assembly 5 to damage the motor. If the inclination angle is increased again, the function will fail until the liquid submerges the suspended air inlet 103 into the air opening of the air duct structure assembly 5.
The inclination angle of the liquid level immersed in the suspended air inlet 103 is related to the height of the immersed suspended air inlet 103 and the actual liquid capacity in the water tank assembly 9, so that if the liquid in the water tank assembly 9 is less or the suspended air inlet 103 is longer, the liquid can not flow into the air channel structural assembly 5 to damage the motor when the machine is inclined by 180 degrees.
The inside of the water-gas separation assembly 1 is provided with two important parts, namely a water sensing device 104 which can limit the maximum water quantity of the sewage tank, the motor assembly 8 stops running immediately when encountering liquid and cannot suck the liquid, the sensitivity of the water sensing device 104 can be adjusted by continuous sensing time, the intensity value set by a sensor after sensing the liquid and the like, and the water quantity in the water tank assembly 9 is ensured not to exceed the water tank and remain in the water-gas separation assembly 1 when the machine runs; the other is a suspended air inlet 103, after limiting the maximum water quantity, the liquid in the water tank assembly 9 can be ensured not to submerge the suspended air inlet 103 even if part of the liquid flows into the water-air separation assembly 1 after the machine rotates for a certain angle, and the liquid can not enter the air channel structure assembly 5 to damage the motor. Under the condition of not affecting the normal water absorption performance, the scheme obviously improves the risk of water leakage when the machine is placed in the use process and after the use.
