In addition, since the dry garbage f in the present embodiment is relatively dry and comfortable in the taken-out state, it will not adhere to the filter basket 42, and the operator can clean the dry garbage f from the filter basket 42 only by tilting the filter basket 42. In addition, the dry garbage f of the embodiment is not always soaked in the wet garbage b, so that the breeding of bacteria in the dry garbage f can be effectively avoided.

Preferably, as shown in fig. 4 and 8, the partition plate 421 is provided with a plurality of second filtering holes 4211, the second filtering holes 4211 are elongated holes, and the plurality of second filtering holes 4211 are uniformly distributed around the central line of the partition plate 421, so that the wet garbage b can uniformly flow downward at each position of the partition plate 421, the blockage of part of the second filtering holes 4211 due to the non-uniform distribution of the second filtering holes 4211 is avoided, and the solid-liquid separation efficiency of the filter basket 42 is improved.

Preferably, as shown in fig. 3 and 4, a through hole 4212 is formed in the middle of the partition 421, and the pipe body 31 passes through the through hole 4212 to be connected to the adaptor pipe 32, 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 4212 extends upwards to form the conduit 423, the pipe body 31 is inserted into the conduit 423, the outer peripheral surface of the pipe body 31 is abutted against the inner wall of the conduit 423, 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 inclined in the box body 1.

Preferably, as shown in fig. 3 and 4, the outer circumferential surface of the pipe body 31 is in interference fit with the inner wall of the conduit 423, so that the filter basket 42 and the pipe body 31 can be fixed well, the L5/H can be set to be 1/3-1/2, the filter basket 42 is prevented from sliding down to the bottom surface 11 of the box body 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 arranged independently. 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 423, so that the fixation of the filter basket 42 with the tube 31 at the middle position of the tube 31 can be ensured. In addition, the diameter of the upper end of the tube 31 is smaller than the diameter of the inner hole of the guide tube 423, which also facilitates the quick assembly and disassembly of the filter basket 42 and the tube 31.

Preferably, as shown in fig. 3 and 8, the partition 421 is inclined downwards from the through hole 4212 to the edge of the partition 421, 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 421. In addition, when the projected area of the partition 421 on the horizontal plane is constant, the above structure can increase the surface area of the entire partition 421, increase the total area of the plurality of second filtering holes 4211, and improve the separation efficiency between the dry garbage f and the wet garbage b.

Preferably, as shown in fig. 3, the upper edge of the annular side peripheral plate 422 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 422 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 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 upper edge of the annular side peripheral plate 422 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 422 is in sealing contact with the inner peripheral surface of the tank body 1, the filter basket 42 can be prevented from being displaced relative to the tank body 1 even if the foul water tank 10 vibrates.

In addition, as shown in fig. 3, the cross-sectional area of the space surrounded by the annular side circumferential plate 422 is gradually reduced from top to bottom, so that a gap exists between the filter screen 422 and the inner circumferential surface of the housing 1, and the wet garbage b can enter the space between the filter mechanism 4 and the bottom surface 11 through the first filter holes 42221 of the filter screen 422, thereby improving the efficiency of the mixed liquid a in separating the dry garbage f from the wet garbage b.

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.

Example two

The present embodiment provides a cleaning device 1000, the structure of the cleaning device 1000 is substantially the same as that of the cleaning device 1000 of the embodiment, as shown in fig. 16, and the main difference between the two is:

as shown in fig. 16, the lid body 2 includes a first shielding plate 26, the first shielding plate 26 is pivotally connected to the lid body 21, and when the lid body 21 is inserted into the box body 1, the top end of the tube 31 abuts against the first shielding plate 26, so that the first shielding plate 26 blocks the dust discharge port 212, and dust d can be stored between the lid body 21 and the first shielding plate 26. When the cover body 2 is detached from the box body 1, the first shielding plate 26 rotates relative to the cover body 21 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 filter basket 42 below through the dust discharge opening 212, and an operator can clean the filter basket 42 simultaneously by cleaning 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 second pivot shaft, a torsion spring is sleeved on the second 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 realize that the first shielding plate 26 automatically opens the dust discharge opening 212, so that the dust d can better fall into the filter basket 42. 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.

In addition, as shown in fig. 16, since the cover 2 in this embodiment eliminates the dust deposition barrel 23, the inside of the box 1 can have a larger empty space, and the baffle 22 in this embodiment is annularly arranged and surrounds the periphery of the section of the sewage pipe 3 near the sewage outlet 3231 by one circle, so that the area of the baffle 22 on the periphery of the sewage pipe 3 is larger, more solid wastes f in the mixed liquid a can be remained on the solid surface of the baffle 22, and a better separation effect on the solid wastes f and the liquid wastes b in the mixed liquid a can be realized.

In addition, the structure of the filtering mechanism 4 of the present embodiment is slightly different from the filtering mechanism 4 of the first embodiment, and the two main differences are that, as shown in fig. 16 and 17, the filtering mechanism 4 includes a handle 43 and a filter basket 42, the filter basket 42 is connected to the handle 43, the distance between the upper end surface of the handle 43 and the opening 12 along the vertical direction is 10mm to 20mm, when the cover body 2 is detached from the box body 1, an operator can take out the filter basket 42 from the box body 1 by holding the handle 43 with hands, and the structure of the filtering mechanism 4 is simple and convenient for the operator to operate.

In addition, as shown in fig. 17, 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-slip 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, the first side plate 4322, the third side plate 4324 and the connecting plate 4321 are formed with a docking port 4326 at the upper end of the handheld portion 432, as shown in fig. 18, the cross section of the partition 421, the cross section of the accommodating space in the box 1 and the cross section of the cover 2 are the same in shape and size and are non-circular, when the filter basket 42 is located in the accommodating space and the cover 2 is plugged into the opening 12, the docking port 4326 is located below the air inlet 211 and is opposite to the air inlet 211, so that the air in the accommodating space enters the cyclone filter assembly 5 through the docking port 4326 and the air inlet 211.
