As shown in fig. 6, when the liquid level in the dirty liquid storage chamber 220 is low or the angle at which the dirty liquid tank 22 is tilted backward is small, the dirty liquid and the air mixed together flow upward from the fluid inlet passage inside the dirty liquid inlet pipe 26 and flow out through the outlet port 252, and then the mixed fluid collides with the inner top surface of the shield cover 26. Most of the dirty liquid falling through the liquid falling port 2201 falls into the gap 242 through the enclosure of the float body 241 and flows into the dirty liquid storage chamber 220 through the gap 242, and a small part of the dirty liquid splashes to the outside of the float body 241 and directly falls into the dirty liquid storage chamber 220; the air escaping through the liquid drop port 2201 flows upward and flows to the outside of the dirty liquid chamber 220 through the air discharge port 2202.
As shown in fig. 7, when the liquid level in the dirty liquid storage chamber 220 is high and the angle at which the dirty liquid tank 22 is tilted backward is large, a part of the dirty liquid stored in the dirty liquid storage chamber 220 flows backward into the upper standby chamber 223, thereby preventing the dirty liquid from directly flowing out of the dirty liquid tank 22 through the exhaust port 2202.
The operation of the vacuum cleaner 100 is described below:
as shown in fig. 8, when the hand-held vacuum cleaner 4 and the upright part 20 are coupled through the hollow hard tube 3, the inlet stub 40 communicates with the exhaust pipe 224. When the handheld vacuum cleaner is started to work, the upright part 20 inclines backwards (the inclination angle is smaller), at the moment, the upper surface 2413 and the lower surface 2414 of the buoy body 241 approach the horizontal plane downwards, the cleaning liquid in the cleaning liquid tank 23 is continuously conveyed to the roller brush 13 and then is applied to the surface to be cleaned through the rotating roller brush 13, the mixed fluid of air and dirty liquid is rolled up by the rotating roller brush and enters the cleaning head part 10 from the suction port 14 under the suction action of the vacuum motor device 42, then sequentially flows upwards through the dirty liquid inlet pipe 25, the mixed fluid of air and dirty liquid flowing in from the outlet end 252 at the upper part of the dirty liquid inlet pipe 25 collides with the inner top surface of the shielding cover 26 at the upper side, the collided air and dirty liquid change the flowing direction and flow out from the liquid outlet 2201 at the lower side, the dirty liquid flows into the gap 242 at the lower side under the action of gravity and enters the dirty liquid receiving chamber 220 through the lower side of the gap 242, the air will escape from the dirty liquid compartment 220 through the air outlet 2202, and flow into the hollow hard tube 3 through the air outlet pipe 224, then enter the dust collecting bucket of the handheld vacuum cleaner 4 through the air inlet short pipe 40, and finally be exhausted to the outside. Along with the dirty liquid level in the dirty liquid storage chamber 220 continuously rises, the buoy 24 in the dirty liquid storage chamber 220 moves upwards along with the dirty liquid level, so as to drive the plug 27 to move upwards, and when the dirty liquid storage chamber 220 rises to a set liquid level, the plug 27 also moves to the exhaust port 2202 right, so as to block the exhaust port 2202, and then the suction port 15 stops sucking dirty liquid and air, and a user can continue to work the vacuum cleaner after needing to empty the dirty liquid in the dirty liquid tank 22.
As shown in fig. 9, when the handheld vacuum cleaner is started to work, when the backward inclination angle of the upright part 20 is large, part of the dirty liquid stored in the dirty liquid storage chamber 220 flows back into the spare chamber 223 at the upper part, at this time, the exhaust port 2202 can still work normally, and as the equipment further works, when the dirty liquid storage chamber 220 rises to a set liquid level, the plug 27 also just moves to the exhaust port 2202, so that the exhaust port 2202 is blocked, and after that, the user can continue to work the vacuum cleaner after needing to empty the dirty liquid in the dirty liquid tank 22.
In the present case, because the existence of reserve chamber for the foul solution case is when taking place the wide-angle slope or invert from top to bottom, and the foul solution of foul solution recovery room can be temporarily retained in the reserve chamber and effectively prevent the foul solution from flowing from the gas vent, thereby has guaranteed the efficiency of foul solution separation, makes handheld vacuum cleaner use safer.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
