The above directional terms are not intended to limit the present invention.

Example 1

The present embodiment provides an integrated device that can suck sewage and discharge clean air.

Referring to fig. 1 to 4, the dust collecting device 100 includes a main body 20, a water inlet pipe 22, a cover 26, and an air outlet 28. Specific: the main body 20 is barrel-shaped, and the main body 20 forms an accommodating space 30 and has an opening 32. The water inlet pipe 22 extends into the receiving space 30 for sucking in sewage, and the water inlet pipe 22 extends vertically and has an outlet 24. The cover 26 covers the opening 32 of the main body 20 to be engaged with the main body 20, closing the receiving space 30, and the receiving space 30 is used for receiving sewage. An air outlet 28 is typically provided in the cover 26 for discharging clean air. Thus, sewage (solid waste is contained in the sewage) is sucked from the water inlet pipe 22, flows into the containing space 30 from the outlet 24 of the water inlet pipe 22 and is contained in the containing space 30, and clean air is discharged from the air outlet 28.

A suction motor is provided downstream of the air outlet 28 (in the example of fig. 2, on the upper side of the cover 26) for sucking air in the accommodating space 30, thereby creating a negative pressure in the accommodating space 30, which makes it easier for sewage to be sucked into the accommodating space 30.

Referring to fig. 2 and 5, the dust collecting device 100 further includes an extension tube 34 covering the water inlet tube 22, the inner diameter of the extension tube 34 is slightly larger than the outer diameter of the water inlet tube 22, the extension tube 34 is sleeved on the periphery of the water inlet tube 22, and the extension tube 34 can slide along the water inlet tube 22. The extension tube 34 has an extension length slightly shorter than that of the inlet tube 22 so that the extension tube 34 can be conveniently sleeved on the periphery of the inlet tube 22 or removed from the inlet tube 22.

The dust collecting device 100 further comprises a filter orifice plate 36 enclosing the water inlet pipe 22, the filter orifice plate 36 being connected to the extension pipe 34. Specifically, the filter orifice 36 extends laterally from an end of the extension tube 34 remote from the outlet 24 of the inlet tube 22, the filter orifice 36 extending in a direction perpendicular to the direction of extension of the inlet tube 22. Thus, the filter orifice 36 can trap large solid waste after sewage entering from the water inlet pipe 22 is flushed from the water inlet pipe 22 into the accommodating space 30 and falls back.

When the dust collecting device 100 needs to be cleaned, the solid garbage with large particles can be cleaned first, so that the dust collecting device 100 is cleaned more conveniently and thoroughly. After the extension pipe 34 and the filter pore plate 36 are arranged, when the large-particle fixed garbage needs to be cleaned, the extension pipe 34 is lifted, the filter pore plate 36 can be pulled, so that the large-particle fixed garbage deposited on the filter pore plate 36 is pulled out of the accommodating space 30 and cleaned, and the cleaning operation is more convenient and thorough.

In order to better utilize the filter orifice plate 36 to pack large solid waste, the filter orifice plate 36 is spaced from the outlet 24 of the inlet pipe 22, so that a certain space is reserved for the solid waste to be packed by the filter orifice plate 36, and in order to set the filter orifice plate 36 at a certain distance from the outlet 24 of the inlet pipe 22, the inlet pipe 22 needs to have a certain extension length. To meet this extended length, the inlet pipe 22 extends a certain length from the bottom of the main body 20 in a direction toward the cover 26, in the direction shown, the inlet pipe 22 extends vertically.

Outlet 24 of inlet tube 22 forms a plane that is disposed obliquely to the centerline of body 20. Specifically, outlet 24 of inlet tube 22 is disposed obliquely downward in a direction toward filter orifice 36. The inclined outlet 24 allows more sewage to flow down to the filter orifice 36 and more smoothly.

When the inlet pipe 22 is extended from the bottom of the main body 20 in a direction toward the cover 26 by a certain length, the outlet 24 of the inlet pipe 22 is relatively close to the air outlet 28, and when sewage is sucked into the accommodating space 30 from the inlet pipe 22, the sewage is flushed out from the outlet 24 of the inlet pipe 22, and since the suction motor is arranged downstream of the air outlet 28, if part of sewage is flushed into the air outlet 28 after being flushed in from the outlet 24 of the inlet pipe 22, the sewage is discharged from the air outlet 28 into the suction motor, and the motor may be damaged.

To prevent sewage from rushing into the air outlet 28 and damaging the motor, the extension tube 34 has a first arcuate extension 35, the first arcuate extension 35 shielding a portion of the outlet 24 of the inlet tube 22, the first arcuate extension 35 being spaced from the outlet 24. After the first arc-shaped extension part 35 is provided, the first arc-shaped extension part 35 shields part of sewage, so that the sewage can be prevented from entering the suction motor to a certain extent, and the sewage is prevented from damaging the motor.

The dust collection device 100 further includes a handle portion 38 connected to a side of the first arcuate extension 35 remote from the outlet 24. When a user needs to clean the solid garbage in the integrated device, the cover 26 is separated from the main body 20, the handle 38 is held and pulled upwards to pull the extension pipe 34, so that the extension pipe 34 slides upwards along the water inlet pipe 22, and the extension pipe 34 slides upwards to pull the filtering orifice plate 36 upwards, so that the filtering orifice plate 36 which is used for holding the large-particle solid garbage is finally pulled out of the opening 32 along the water inlet pipe 22, and the large-particle solid garbage is cleaned in advance, so that the dust collecting device 100 is cleaned more conveniently and thoroughly.

The cover 26 is provided with a containing groove for containing the handle 38, and when the handle 38 is inserted into the containing groove without cleaning the solid garbage with large particles, the handle 38 can be kept clean; when the lid 26 is opened and the handle portion 38 is disengaged from the receiving groove, the user can clean the large-sized solid garbage in advance by pulling the handle portion 38.

In order to improve the cleaning efficiency, the air outlet 28 of the cover 26 is usually provided with a HEPA (high efficiency air filter) with a larger area, and after the HEPA with a larger area is installed, the space left by the cover 26 is limited, so that the space of the accommodating groove for accommodating the handle portion 38 is limited, the width of the handle portion 38 is relatively narrow, specifically, the width of the handle portion 38 is smaller than the diameter of the extension tube, thereby realizing the required function in the limited space, and the structural design is quite reasonable.

As before, extension tube 34 has a first arcuate extension 35 that obstructs a portion of outlet 24 of inlet tube 22. In order to more fully prevent the contaminated water from rushing out of the outlet port 28 of the cover 26 from the outlet port 24 of the inlet pipe 22, the dust collecting device 100 further includes a second baffle 40, the second baffle 40 covering a portion of the outlet port 24 of the inlet pipe 22, the second baffle 40 being spaced from the outlet port 24. The second baffle 40 has the same function as the first arc-shaped extension 35, that is, the second baffle 40 can also shield sewage, so that the sewage can be prevented from entering the suction motor to cause motor damage.

More preferably, the projection of the end surfaces of the first arcuate extension 35 and the second baffle 40 adjacent to each other in a plane perpendicular to the centerline of the outlet 24 of the inlet conduit 22, in a plane perpendicular to the centerline of the outlet 24, is within the projection of the first arcuate extension 35 and the second baffle 40 of the outlet 24 of the inlet conduit 22. That is, the first arcuate extension 35 in combination with the second baffle 40 may cover the entire outlet 24 of the inlet tube 22, thereby better preventing sewage from entering the suction motor.

Specifically, the second baffle 40 includes a second arcuate extension 42, the second arcuate extension 42 covering a portion of the outlet 24 of the inlet conduit 22 and being spaced from the outlet 24, the projection of the end surfaces of the first arcuate extension 35 and the second arcuate extension 42 adjacent each other being in engagement in a plane perpendicular to the centerline of the outlet 24, the projection of the outlet 24 of the inlet conduit 22 being within the projection of the first arcuate extension 35 and the second arcuate extension 42. Thereby comprehensively preventing the sewage from directly rushing out of the air outlet 28 from the outlet 24 to damage the suction motor; and the first arc extension part and the second arc extension part are respectively independent components, so that the functions are realized together, the operation is simpler and the cost is lower for programs such as die design, installation and the like.

It should be noted that, the surfaces of the first arc-shaped extension portion 35 and the second arc-shaped extension portion 42 where the projections are joined do not need to be identical in height, but only the projection is joined; of course, the two surfaces are identical in height, and all the solutions similar to or the same as the present embodiment are also included in the protection scope of the present invention.

The second arcuate extension 42 extends obliquely downward so as to block the flow of sewage from the outlet 24 and direct the flow of sewage downward.

The second baffle 40 further comprises a vertical extension 44 connected to the second arcuate extension 42, the vertical extension 44 being connected to a side of the second arcuate extension 42 remote from the first arcuate extension 35, the vertical extension 44 extending in a direction parallel to the direction of extension of the inlet conduit 22. Thus, when the sewage is flushed out of the outlet 24, it falls back under the shielding of the first and second

arcuate extensions

35, 42 and the action of gravity, avoiding damage to the suction motor by the sewage flushing out of the air outlet 28, while the vertical extension 44 limits the fall-back range of the sewage, so that the sewage falls back on the side of the vertical extension 44 adjacent to the water inlet pipe 22 under the restriction of the vertical extension 44.

As before, the dust collection device 100 includes a filter aperture plate 36 surrounding the inlet tube 22, and preferably, the projection of the vertical extension 44 onto the filter aperture plate 36 is located within the filter aperture plate 36. Thus, the large-particle solid garbage in the sewage can fall into the range of the filter pore plate 36 under the guidance of the vertical extension part 44, and the structural design is quite reasonable, so that the large-particle solid garbage can be cleaned more conveniently.

The dust collecting device 100 further includes a first baffle 46 disposed in the accommodating space 30, and the first baffle 46 is connected to the filter orifice 36. The first baffle 46 extends in a direction approaching the outlet 24 of the inlet pipe 22. Thus, the first baffle 46 and the filter orifice 36 together form a pocket that can contain solid waste, thereby more reliably trapping large particulate solid waste in the wastewater.

Preferably, the first baffle 46 is perpendicular to the direction of extension of the filter aperture plate 36. The first baffle 46 extends in a direction parallel to the direction of extension of the inlet pipe 22 and the extension pipe 34. Thus, the first baffle 46 and the filter orifice 36 combine to better contain large particulate solid waste in the wastewater and have a regular structure.

Part of the outer wall of the body 20 is recessed inwardly to form a grip. When the dust collecting device 100 is used, a user can conveniently mount the dust collecting device 100 to the cleaning apparatus 200 (shown in fig. 6) or remove it from the cleaning apparatus 200 through the grip.

The gripping portion is adjacent the opening 32 in the upper end of the body 20 and includes an associated vertical plate 48 and inclined plate 50, the vertical plate 48 being adjacent the opening 32 relative to the inclined plate 50, the extension of the inclined plate 50 (not actually present) passing through the air outlet 28 of the cover 26, and a suction motor being provided downstream of the air outlet 28. When the dust collecting device 100 is used, some objects may be bumped, which may cause the sewage in the dust collecting device 100 to shake, and when the sewage shakes, part of the sewage may incline upward along the inclined plate 50 of the grip portion, so that part of the sewage may be flushed out of the air outlet 28 under the guidance of the inclined plate 50 of the grip portion, resulting in the water inlet damage of the suction motor. To solve this problem, the first baffle 46 is disposed adjacent to the inner wall of the main body 20 below the grip portion, and the extending direction of the first baffle 46 is substantially the same as the extending direction of the inner wall of the main body 20.

Accordingly, the gap between the first baffle 46 and the inner wall of the main body 20 is small, and even if collision occurs, only a small amount of sewage in the dust collecting device 100 near the grip portion is shaken, thereby reducing the probability that sewage is flushed to the air outlet 28 along the inclined plate 50 and reducing the risk of damage to the motor.

As before, the second baffle 40 includes a second arcuate extension 42 and a vertical extension 44 that are connected, preferably with the vertical extension 44 and the first baffle 46 being offset vertically and horizontally to form a notch 54, the notch 54 facing the inner wall of the grip. Specifically, vertical extension 44 is relatively upward in the vertical direction, and vertical extension 44 is relatively close to inlet tube 22 in the horizontal direction. Thus, when the dust collecting device 100 shakes, even if a small amount of sewage shakes, part of the sewage rushes up to the grip part to fall back under the action of gravity, and the falling sewage just falls into the space where the notch 54 is located, so that the sewage is prevented from striking other components to cause the sewage to rushing out of the air outlet 28 again.

The dust collecting device 100 further includes a connection plate 52 connecting the filter orifice plate 36 and the first baffle 46, the connection plate 52 having a convex arc shape. The height of the connection plate 52 is lower than the height of the first barrier 46. The connection plate 52 extends in the entire circumferential direction, and the first baffle 46 extends in the circumferential direction at an angle only at a position near the grip portion, for example, in the circumferential direction of 180 degrees or less, so that the amount of material can be reduced, the structure can be simplified, and at the same time, the higher first baffle 46 is provided at the side near the second baffle 40, and it is sufficient to hold the large-particle solid garbage falling under the guidance of the second baffle 40.

It should be noted that, the connection plate 52 extends in the entire circumferential direction, but not that the projection outer contour of the connection plate 52 is circular on a plane perpendicular to the center line of the outlet 24 of the water inlet pipe 22, and the outer contour of the connection plate 52 can be correspondingly adjusted according to the shape of the main body 20 and the space that may be occupied by other components, and all the solutions that are the same as or similar to the present embodiment are included in the protection scope of the present invention.

The inlet pipe 22 is disposed near one side wall of the main body 20 and the first baffle 46 is disposed near the other side wall of the main body 20, so that the area of the filter orifice 36 between the outlet 24 of the inlet pipe 22 and the first baffle 46 is as large as possible, thereby holding large solid wastes, which are discharged from the outlet 24 and fall on the filter orifice 36 under the guide of the second baffle 40, in a larger range.

Preferably, the first baffle 46, the connection plate 52, the filter orifice 36, the extension tube 34, and the first handle portion 38 are integrally provided. Simple structure reduces the installation procedure, simple to operate.

In summary, when the dust collecting device 100 provided in this embodiment is used, under the action of the suction motor at the downstream of the air outlet 28, sewage enters from the water inlet pipe 22 and flows out from the outlet 24 of the water inlet pipe 22, and the sewage flowing out from the outlet 24 falls back to the filter orifice 36 under the guidance of the first arc-shaped extension portion 35, the second arc-shaped extension portion 42 and the vertical extension portion 44 and the action of gravity, and the filter orifice 36 traps large-particle fixed garbage. When the large-particle solid garbage is required to be cleaned, the cover body 26 is separated from the main body 20, the handle part 38 is exposed, and the filter pore plate 36 can be pulled out of the main body 20 along with the extension pipe 34 to be cleaned by lifting the handle part 38, so that the use is very convenient.

In order to disassemble and assemble the dust collecting device 100 and the cleaning apparatus 200, part of the outer wall of the main body 20 is recessed inwards to form a gripping portion, the first baffle 46 is disposed in the accommodating space 30 of the dust collecting device 100, the first baffle 46 is disposed below the gripping portion and close to the inner wall of the main body 20, and the extending direction of the first baffle 46 is approximately the same as that of the inner wall of the main body 20. Because the gap between the first baffle 46 and the inner wall of the main body 20 is small, even if the dust collecting device 100 collides in use, only a small amount of sewage in the position, which is close to the gripping portion, in the dust collecting device 100 shakes, thereby reducing the probability that the sewage rushes out of the air outlet 28 along the inclined plate 50 and reducing the risk of damage to the motor. And the first baffle 46 is connected with the filter orifice plate 36, and the first baffle 46 is equivalent to the fence of the filter orifice plate 36, and the first baffle 46 can prevent the large-particle solid garbage from falling from the filter orifice plate 36 to a certain extent, so that the structural design is quite reasonable.

Example 2

Thus, the spraying system sprays the cleaning liquid to the surface to be cleaned, the cleaning system cleans the surface to be cleaned with the liquid, and then the sewage recovery system recovers the sewage. Since the cleaning apparatus 200 includes the dust collecting device 100 of embodiment 1, the dust collecting device 100 can prevent the water and sewage from flowing out of the air outlet 28 to the greatest extent and damage the suction motor, and therefore the cleaning device provided in this embodiment can prevent the water and sewage from flowing out of the air outlet 28 to the greatest extent and damage the suction motor, thereby improving the service life and saving the use cost of consumers.

It will be apparent that the embodiments described above are merely some, but not all, embodiments of the invention. Based on the embodiments of the present invention, those skilled in the art may make other different changes or modifications without making any creative effort, which shall fall within the protection scope of the present invention.
