Preferably, as shown in fig. 8, the height of the annular side peripheral plate 4212 is 20mm to 50mm, and compared with the supporting frame 421 which only includes the partition plate 4211 in the prior art, the annular side peripheral plate 4212 of the filter basket 42 of the present embodiment has a certain height, which can achieve the effect of increasing the accommodating space for storing the dry garbage f, thereby achieving the effect of storing more dry garbage f by the filter basket 42.

Preferably, as shown in fig. 4 and 8, the second filtering holes 42111 are elongated holes, and the plurality of second filtering holes 42111 are uniformly arranged around the center line of the partition plate 4211, so that the wet garbage b can uniformly flow downward at each position of the partition plate 4211, the blockage of part of the second filtering holes 42111 due to the non-uniform distribution of the second filtering holes 42111 is avoided, and the solid-liquid separation efficiency of the filter basket 42 is improved.

Preferably, a through hole 42112 is formed in the middle of the partition 4211, and the pipe body 31 is connected with the adapter pipe 32 through the through hole 42112, so that the filter basket 42 is not tilted in the housing 1 when the cleaning apparatus 1000 is tilted or laid flat. Furthermore, the through hole 42112 extends upward to form a conduit 4213, the pipe body 31 is inserted into the conduit 4213, the outer peripheral surface of the pipe body 31 abuts against the inner wall of the conduit 4213, the contact area between the filter basket 42 and the pipe body 31 can be increased, and the filter basket 42 can be further prevented from being not inclined in the box body 1. Preferably, as shown in fig. 3 and 4, the outer peripheral surface of the pipe 31 is in interference fit with the inner wall of the conduit 4213, so that the filter basket 42 and the pipe 31 can be well fixed, the filter basket 42 is prevented from sliding down to the bottom surface 11 of the box 1, the filter basket 42 is prevented from being in contact with the wet garbage b filtered out of the dry garbage f again, and the dry garbage f and the wet garbage b are ensured to be independently arranged. Specifically, the diameter of the tube 31 decreases gradually from bottom to top, and the outer diameter of the tube 31 at the middle position is the same as the inner hole diameter of the conduit 4213, so that the filter basket 42 can be fixed to the tube 31 at the middle position of the tube 31. In addition, the diameter of the upper end of the tube 31 is smaller than the diameter of the inner bore of the conduit 4213, which also facilitates the installation of the filter basket 42 onto the tube 31 by the operator.

Preferably, the partition 4211 is inclined downwards from the through hole 42112 to the edge of the partition 4211, so that the mixed liquid a tends to flow downwards, the solid-liquid separation effect of the filter basket 42 is improved, and the liquid is prevented from depositing on the partition 4211. In addition, when the projected area of the partition plate 4211 on the horizontal plane is constant, the above structure can increase the surface area of the whole partition plate 4211, and the total area of the plurality of second filtering holes 42111 is increased, thereby improving the separation efficiency of the dry waste f and the wet waste b.

Preferably, as shown in fig. 3, an upper edge of the annular side peripheral plate 4212 is in sealing contact with the inner peripheral surface of the case 1. Firstly, large particles or large-volume dry garbage f cannot pass through a gap between the edge of the upper end of the annular side peripheral plate 4212 and the inner peripheral surface of the box body 1, so that the large particles or large-volume dry garbage f is left in the filtering mechanism 4 after the filtering mechanism 4 is subjected to separation, and the large particles or large-volume dry garbage f is prevented from entering the wet garbage b in the filtering mechanism 4. In addition, the wet dust b between the filter mechanism 4 and the bottom surface 11 does not pass through the gap between the edge of the upper end of the annular side peripheral plate 4212 and the inner peripheral surface of the casing 1, and the risk that the wet dust b between the filter mechanism 4 and the bottom surface 11 enters the filter mechanism 4 due to vibration can be completely avoided. Of course, since the upper edge of the annular side peripheral plate 4212 is in sealing contact with the inner peripheral surface of the tank body 1, the filter basket 42 and the tank body 1 can be prevented from being displaced relative to each other even if the foul water tank 10 vibrates.

In addition, as shown in fig. 3, the cross-sectional area of the annular side peripheral plate 4212 is gradually reduced from top to bottom, so that a gap exists between the filter screen 422 and the inner peripheral surface of the housing 1, and the wet trash b can enter the space between the filter mechanism 4 and the bottom surface 11 through the first filter holes 4221 in the filter screen 422, thereby improving the efficiency of separating the dry trash f from the wet trash b by the mixed liquid a.

For convenience of understanding, the working principle of the waste water tank 1 under three different working conditions will be described with reference to fig. 3.

As shown in fig. 3, when the cleaning apparatus 1000 is only operated in a dust suction mode, the fluid M only includes dust and air, a portion of the dust in the fluid M discharged from the sewage outlet 3231 moves downward and falls into the filter basket 42, another portion of the dust mixed with air enters the cyclone filter assembly 5 through the air inlet 211 to form a mixed gas c, the dust d remains in the dust collecting bucket 53, and the clean gas e is discharged from the cyclone filter assembly 5.

As shown in fig. 3, when the cleaning apparatus 1000 is only operated to absorb water, the fluid M includes only water and air, and the water in the fluid M discharged from the sewage outlet 3231 moves downward to be stored in the bottom of the tank 1, thereby recovering the sewage. The air mixed in the fluid M passes through the air inlet 211 and the cyclone filtering assembly 5 in order and is discharged from the cyclone filtering assembly 5.

As shown in fig. 3, when the cleaning device 1000 is in a dust and water mixture treatment condition, the fluid M is separated from the mixed gas c at the sewage outlet 3231, the mixed liquid a has a general downward movement tendency, the mixed liquid a is separated from the dry garbage f and the wet garbage b at the filtering mechanism 4, the dry garbage f is left in the filtering mechanism 4, and the wet garbage b enters the bottom of the box body 1. The mixed gas c is separated from the clean gas e and the dust d in the cyclone filter assembly 5, the dust d is remained in the dust collecting barrel 53, and the clean gas e is discharged out of the cyclone filter assembly 5 through the gas outlet 51111.

When the cover 2 is detached from the box 1, the first shielding plate 26 rotates relative to the cyclone filtering mechanism air duct 51 under the action of gravity, so that the dust discharge opening 212 is opened, dust d in the dust storage space can automatically fall into the filtering basket 42 below through the dust discharge opening 212, and an operator can clean the filtering basket 42 simultaneously with the dust d and dry garbage f.

As a preferred scheme, the first shielding plate 26 is connected to the lid body 21 through a pivot shaft, a torsion spring is sleeved on the pivot shaft, two ends of the torsion spring are respectively abutted to the first shielding plate 26 and the lid body 21, and after the lid body 2 is detached from the box body 1, the elastic restoring force of the torsion spring can open the dust discharge opening 212 automatically by the first shielding plate 26, so that the dust d can fall into the filter basket 42 well. Preferably, when the torsion spring is in a natural state, the plane where the first baffle 26 and the dust discharge port 212 are located is 60 degrees, so that when the lid body 21 is inserted into the box body 1, the tube 31 can push the first baffle 26 smoothly to close the dust discharge port 212.

In addition, as shown in fig. 16, the sewage pipe 3 is integrally formed, and the processing and forming efficiency of the sewage pipe 3 can be improved.

Specifically, the handle 43 includes a connecting plate 4321, a first side plate 4322, a second side plate 4323, and a third side plate 4324, the connecting plate 4321 is connected to the other end of the connecting rod 431, the first side plate 4322, the second side plate 4323, and the third side plate 4324 are perpendicular to the connecting plate 4321 and located on one side of the connecting plate 4321, the first side plate 4322 and the third side plate 4324 are connected to two sides of the second side plate 4323, and a distance between the first side plate 4322 and the third side plate 4324 gradually increases from bottom to top, so that the handle 43 is inverted to be trapezoidal, which is convenient for an operator to hold. In addition, as shown in fig. 16, the filter mechanism 4 further includes a reinforcing plate rib 45, and the reinforcing plate rib 45 is connected between the connecting rod 431 and the handle 43, so that the overall strength and hardness of the filter mechanism 4 are enhanced, the deformation problem of the filter mechanism 4 in the repeated taking process is avoided, and the service life of the filter mechanism 4 is prolonged.

In addition, in order to improve the holding effect of the operator on the hand-held portion 432 and avoid the slipping problem between the hand and the hand-held portion 432, anti-slipping lines are formed on the outer surfaces of the first side plate 4322, the second side plate 4323 and the third side plate 4324. Specifically, as shown in fig. 17, the first side plate 4322, the second side plate 4323 and the third side plate 4324 are respectively provided with a plurality of air holes 4325 arranged at intervals, and the plate-shaped structures between the air holes 4325 form anti-slip patterns.

As shown in fig. 16 and 17, the partition 4211 is constructed with a reverse flow prevention structure 44 so that sewage introduced into the upper space of the tank 1 from the sewage pipe 3 can be stored in the lower space at least via the reverse flow prevention structure 44, and the reverse flow prevention structure 44 prevents the sewage in the lower space from flowing therethrough into the upper space.

With the cleaning apparatus 1000 having the wastewater tank 10, when the shaft 200 (or the wastewater tank 10) is substantially erected (for example, when the angle with respect to the horizontal plane is 90 degrees or more and 60 degrees, hereinafter, simply referred to as "erected"), wastewater is sucked into the wastewater pipe 3, flows into the upper space from the wastewater pipe 3, then enters the lower space through the backflow preventing structure 44, and is stored in the lower space. When the shaft 200 (or the wastewater tank 10) is inclined to a large extent (for example, the angle with respect to the horizontal plane is less than or equal to 30 degrees, even the angle with respect to the horizontal plane is about 2 degrees, which will be referred to as "flat"), the backflow preventing structure 44 prevents wastewater in the lower space from flowing backward through the backflow preventing structure 44 and entering the upper space, so that wastewater does not flow to the motor 20, the motor 20 does not stop, and the cleaning device 1 can still perform cleaning normally. Thus, the cleaning apparatus 1 with the sewage tank 10 can use the shaft 200 not only upright but also largely tilt the shaft 200 even flat, which greatly facilitates the user's use.
