Wherein an airflow outlet 453 is integrated into the top of the filter cavity 452 and the filter 47 is configured to be removable from the airflow outlet 453. As shown in fig. 2, when the contaminated fluid collection container 4 is attached to the main body 22, the airflow outlet 453 is in airflow communication with the suction motor 5.

The removable cover assembly is further arranged with longitudinal walls 455 located at the lower side of the cover body 45 and extending in the up-down direction, the airflow inlets 451 and the cross tubes 46 being arranged at the front and rear sides of the longitudinal walls 455, respectively; the longitudinal wall 455 is effective to prevent liquid contaminants flowing from the cross tube 46 from entering the airflow inlet 451 directly under the action of the suction motor 5.

The cleaning device 100 further comprises a fluid level sensing arrangement carried on the cap body 45, the fluid level sensing arrangement comprising a first fluid level sensing assembly having a pair of first probes 481 and a second fluid level sensing assembly having a pair of second probes 482. A pair of first probes 481 are disposed in tandem with a pair of second probes 482, and the cross tube 46 and riser 43 are positioned between the pair of first probes 481 and the pair of second probes 482. The pair of first probes 481 and the pair of second probes 482 are arranged in a left-right opposed manner. The cleaning apparatus 100 is configured to alarm to the outside and automatically shut down the suction motor at the same time when any one of the first liquid level sensing assembly and the second liquid level sensing assembly detects that the dirty liquid reaches the corresponding position.

As shown in fig. 7, a pair of first probes 481 and a pair of second probes 482 are both located within the upper chamber 421; wherein the pair of first probes 481 are positioned at the front side of the pair of second probes 482, and the pair of first probes 481 are positioned at the lower side of the pair of second probes 482.

With continued reference to fig. 10-11, the removable cap assembly further includes a barrier wall 456 disposed between the cross tube 46 and the pair of second probes 482. The blocking wall 456 has a portion protruding outward in a left-right direction with respect to the second and third fluid outlets to separate the pair of second probes 482 from the second and third fluid outlets; the blocking wall 456 can effectively prevent the dirty liquid flowing out from the second and third fluid outlets from directly flowing into the pair of second probes 482, which may cause a false alarm of the cleaning apparatus 100.

Referring to fig. 2, 3, 12 and 13, the operation principle of the contaminated liquid recovery tank 4 will now be described: when the cleaning apparatus 100 performs a cleaning operation on a surface to be cleaned without obstacles, the apparatus is adjusted to a posture substantially as shown in fig. 2; the suction motor 5 is activated and soiled liquid on the surface to be cleaned is drawn in via the suction nozzle 16, then via the stand pipe 43 into the transverse pipe 46 and flows into the upper chamber 421 via the first, second and third fluid outlets of the transverse pipe 46. The first fluid outlet 462 can allow part of the dirty liquid to directly pass out under the action of inertia, so that noise caused by the fact that the dirty liquid directly impacts the transverse pipe 46 is greatly reduced.

The dirty liquid collecting container 4 is inclined rearward with the upright body and substantially takes the posture shown in fig. 12 in which the partition main body 441 is inclined forward and downward. The contaminated liquid entering the upper chamber 421 will be directed, in large part, to a pair of notches 4414 and then flow into the lower chamber 422. The partition 44 can confine the dirty liquid in the lower chamber 422 to avoid that a user, during pushing and pulling the cleaning base 1, causes the liquid level in the dirty liquid recovery container 4 to fluctuate greatly so that part of the dirty liquid is sucked to the suction motor 5; when the lower chamber 422 is full, the liquid level rises to reach the pair of first probes 481, the pair of first probes 481 will recognize that the dirty liquid level reaches the position, and at this time, the cleaning device 100 will issue an alarm to the outside based on the monitoring result of the first liquid level sensing assembly, so as to remind the user to pour out the dirty liquid. At the same time, to protect the cleaning device, the device will automatically shut down the suction motor.

When the cleaning device 100 performs a cleaning operation on a bed bottom, a cabinet bottom and other height-limited environments, the device is adjusted to a posture substantially as shown in fig. 3; when the suction motor 5 is operated, dirty liquid on the surface to be cleaned is sucked in through the suction nozzle 16, then enters the transverse pipe 46 through the vertical pipe 43 and flows into the upper chamber 421 through the first, second and third fluid outlets of the transverse pipe 46;

the dirty liquid collecting container 4 is inclined rearward with the upright body and is substantially in the posture shown in fig. 13. In this attitude, since the pair of notches 4414 are located above the cross pipe 46, i.e., at a higher position of the upper chamber 421, the dirty liquid flowing in from the cross pipe 46 at this time will be temporarily stored in the upper chamber 421, and the dirty liquid in the lower chamber 422 will not flow into the upper chamber 421; when the dirty liquid in the upper chamber 421 reaches the pair of second probes 482, the cleaning device 100 will send out an alarm to the outside to remind the user to pour the dirty liquid; at the same time the device will automatically shut down the suction motor. It can be understood that, when the apparatus posture shown in fig. 3 is short, and the cleaning apparatus 100 is returned from the working posture shown in fig. 3 to the working posture shown in fig. 2, the dirty liquid temporarily stored in the upper chamber 421 flows into the lower chamber 422 through the pair of notches 4414.

The cleaning equipment can increase the backward inclination angle of the vertical machine body under the condition of ensuring the safe use of the equipment, so that the whole cleaning equipment can be changed into a lower posture for operation so as to extend into areas such as a low cabinet, a bed bottom and the like for cleaning operation.

The above embodiments are merely illustrative of the technical concepts and features of the present application, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application. All equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
