The cleaning apparatus of the present disclosure may be a floor washing robot, a hand-held floor washing machine, or the like, known to those skilled in the art, which includes a body and a floor brush assembly disposed on the body. The main body is used for carrying various components in the cleaning device, such as a charging device, a display screen, a motor component and the like. The scrubbing brush subassembly is used for cleaning the working face, and the scrubbing brush subassembly can supply water to working face or scrubbing brush subassembly at the in-process of work, and the scrubbing brush subassembly can form dirty together that sewage, foreign matter mix after cleaning, and under the negative pressure effect that motor element provided, dirty can be extracted and deposit in the slop pail.

The cleaning equipment is provided with a negative pressure channel and a liquid inlet channel in the sewage bucket. One port of the negative pressure channel can be butted with an air channel of the machine body, and the motor assembly pumps out air in the sewage bucket through the air channel and the negative pressure channel so as to form negative pressure in the sewage bucket; one end of the liquid inlet channel is a liquid inlet, the other end of the liquid inlet channel is a liquid outlet, the liquid inlet can be connected with an external sewage suction pipeline, and under the action of negative pressure, external liquid enters the sewage barrel from the liquid outlet through the sewage suction pipeline and the liquid inlet channel.

In the prior art, the liquid entering the slop pail from the liquid channel has a fast flow speed, and a small part of the liquid enters the negative pressure channel along with the air flow in the slop pail, so that a motor assembly or other elements communicated with the negative pressure channel are contacted with the liquid, and the damage is caused.

Therefore, a water retaining mechanism is further arranged in the sewage bucket, and the water retaining mechanism comprises a water retaining plate which is arranged at the opposite position of the liquid outlet of the liquid inlet channel and is provided with a through hole. Liquid discharged from the liquid outlet can directly flow to the water baffle, the water baffle can play a role in buffering and decelerating liquid, the liquid is prevented from moving along with the air flow direction in the sewage bucket to enter the negative pressure channel, other components and parts of the cleaning equipment are prevented from entering the cleaning equipment through the negative pressure channel, the cleaning equipment is prevented from being damaged, and the service life of the cleaning equipment is prolonged.

For easy understanding, specific structures and operation principles of the present disclosure are described in detail below with reference to fig. 1 to 7.

Example one

Referring to fig. 1, the present disclosure provides a cleaning apparatus including a body (not shown), a slop pail 1, the slop pail 1 being detachably mounted to the body. When cleaning, the sewage bucket 1 can be assembled on the machine body, and the sewage bucket 1 is used for accommodating dirt generated in the cleaning process; after the washing is completed, the waster tub 1 may be detached, and the soil in the waster tub 1 is dumped and washed.

The negative pressure channel 21 and the liquid inlet channel 31 are arranged in the slop pail 1, the slop pail can form negative pressure through the negative pressure channel 21, and external liquid can enter the slop pail 1 through the liquid inlet channel 31 under the action of the negative pressure. For example, in the cleaning device of the present disclosure, one end of the negative pressure channel 21 may be butted with the air duct of the body, and one end of the liquid inlet channel 31 may be connected with the external dirt suction pipe. When the motor assembly of the cleaning device works, the cleaning device can pump out air in the sewage bucket 1 through the air duct and the negative pressure channel 21 so as to form negative pressure in the inner cavity of the sewage bucket 1, at the moment, under the action of the negative pressure, external liquid can flow through the sewage suction pipeline and the liquid inlet channel 31 and enter the sewage bucket 1 from the liquid outlet 311, and therefore the liquid cleaned by the cleaning device is collected.

It should be noted that, in the above process, the negative pressure channel 21 in the slop pail can make the slop pail form a flowing air flow in the slop pail 1, and the flowing direction is from the liquid outlet 311 of the liquid inlet channel 31 to one end of the negative pressure channel 21, so that a small part of the liquid can move along with the air flow direction and enter the negative pressure channel 21.

In order to prevent the liquid from entering the negative pressure passage 21, a water blocking mechanism is further disposed in the slop pail 1, the water blocking mechanism includes a water blocking plate 41 having a through hole 411, the water blocking plate 41 is disposed at a position opposite to the liquid inlet passage 31, for example, the water blocking plate 41 may be disposed above the liquid outlet 311, and the liquid outlet 311 is located in an orthographic projection of the water blocking plate 41 toward the bottom of the pail. When the liquid velocity of flow is very fast, the liquid that enters into slop pail 1 by liquid outlet 311 can directly strike on the face of breakwater 41, breakwater 41 can play the effect of buffering speed reduction to liquid, prevents liquid and follows the air current direction and further move, and the liquid that is blockked is because the velocity of flow reduces, and the lower liquid of velocity of flow then can flow down under the effect of gravity to can prevent that liquid from entering into negative pressure passageway 21 along with the air current that flows, cause cleaning device's damage.

Referring to fig. 1 and 2, in one embodiment of the present disclosure, the water blocking mechanism includes a water blocking chamber surrounded by the water blocking housing 42, the water blocking plate 41 is disposed in the water blocking chamber, for example, the water blocking plate 41 may be disposed at a middle position of the water blocking chamber, and an edge of the water blocking plate 41 may be configured in a shape fitting an inner side wall of the water blocking housing 42, or the water blocking plate 41 may be injection-molded from a side wall of the water blocking housing 42 such that the water blocking plate 41 partitions the water blocking chamber into a first water blocking chamber 421 and a second water blocking chamber 422.

In addition, in the water blocking mechanism of the present disclosure, referring to fig. 3, through holes 411 are provided on the water blocking plate 41, the number of the through holes 411 may be specifically set as required, for example, a plurality of the through holes 411 may be distributed on the water blocking plate 41. When the liquid impacts the water baffle 41, part of the liquid will flow up above the water baffle 41 through the through holes 411, thereby preventing the liquid from accumulating below the water baffle 41 and causing splashing and flowing from the gap to the negative pressure channel 21.

According to the above example, after the liquid impacts the water baffle 41, most of the liquid is blocked by the plate surface of the water baffle 41 on one side of the first water baffle cavity 421, and after the liquid loses power, the liquid slowly flows to the bottom of the sewage bucket 1 under the action of gravity; meanwhile, a small amount of liquid can enter the second water retaining cavity 422 through the through holes 411 of the water retaining plate 41, and fall on the plate surface of the water retaining plate 41 positioned in the second water retaining cavity 422, and under the action of gravity, the liquid can flow along the water retaining plate 41 and flow to the bottom of the sewage bucket 1 through the gaps between the structures, so that the liquid flowing out of the liquid inlet channel 31 is buffered.

Referring to fig. 2 and 3, the water-retaining chamber has an upper end opening toward the top of the slop pail 1, a lower end opening allowing the liquid outlet 311 to protrude thereinto, and an open end opened at a side wall of the water-retaining chamber.

With continued reference to fig. 1, the liquid outlet 311 of the inlet channel 31 may be higher than the lower end opening of the water retaining chamber in the height direction of the slop pail 1, and it can also be understood that the lower end opening of the water retaining chamber partially overlaps with the liquid outlet 311 of the inlet channel 31 in the height direction, so that the external liquid directly enters into the water retaining chamber from the liquid outlet 311. Of course, it is obvious to those skilled in the art that the liquid outlet 311 may be flush with or lower than the lower opening of the water-blocking chamber, and will not be described in detail herein.

Referring to fig. 2, in one embodiment of the present disclosure, the sidewall of the water-blocking chamber may form an open end, such that the water-blocking housing 42 may be configured to enclose a C-shaped structure, and the open end opened on the sidewall of the water-blocking housing 42 is the open end of the water-blocking chamber. It is also understood that the water-retaining chamber enclosed by the water-retaining housing 42 in the height direction is not closed.

Referring to fig. 3 and 4, the open end of the water blocking chamber may be positioned near the sidewall of the slop pail 1, and the edge of the plate surface of the water blocking plate 41 on the side facing the open end of the water blocking chamber may extend to the open end position and form a gap 412 with the sidewall of the slop pail 1, and the gap 412 may allow liquid to flow. For example, after the liquid enters the second catch chamber 422, the liquid falls on the surface of the splash guard 41 on the side of the second catch chamber 422, and the decelerated liquid flows along the surface toward the edge of the splash guard 41 under the action of its own weight and flows toward the bottom of the slop pail 1 through the gap 412 between the splash guard 41 and the sidewall of the slop pail 1. In addition, the liquid flows down along the side wall of the slop pail 1, so that the liquid is guided to flow to the bottom of the slop pail 1, and is prevented from splashing or falling in the air and being brought into the negative pressure channel 21 by the air flow.

In another embodiment of the present disclosure, the open end of the water blocking chamber may be further configured to form a gap 412 for liquid to flow through with the sidewall of the slop pail 1, and the edge of the water baffle plate 41 extends to the position of the edge of the open end of the water blocking chamber, so that the liquid can flow down along the sidewall of the slop pail 1 through the edge of the water baffle plate 41 and the edge of the open end of the water blocking chamber, and the influence of the gas flow in the slop pail 1 on the liquid is reduced.

Referring to fig. 3, in one embodiment of the present disclosure, the water deflector 41 is configured to be obliquely disposed in the water blocking chamber, with the side of the water deflector 41 adjacent to the open end being lower than the side of the water deflector 41 away from the open end, and with reference to the direction of view, the water deflector 41 in the water blocking chamber is an inclined surface. The liquid entering the second catch chamber 422 flows along the inclined splash plate 41 from the side away from the open end to the side near the open end under the action of gravity, and then flows to the side wall of the slop pail 1 through the gap 412 between the splash plate 41 and the slop pail 1. The inclined arrangement of the baffle plate 41 facilitates guiding the liquid in the second baffle chamber 422 to flow most of the liquid onto the side wall of the slop pail 1.

Referring to fig. 2 and 3, in one embodiment of the present disclosure, an upper end opening of the second catch chamber 422 is configured to be closed by the top of the tub 1. The liquid entering the second catch chamber 422 through the through hole 411 from the first catch chamber 421 may still have a fast flow velocity, and this portion of liquid may impact the top of the slop pail 1, and after losing power, fall back to the plate surface of the catch plate 41 on one side of the second catch chamber 422 under the action of gravity, thereby playing a role of buffering and decelerating the liquid for the second time, and then the liquid flows along the inclined plate surface and flows onto the side wall of the slop pail 1 through the gap 412.

Referring to fig. 5, in one embodiment of the present disclosure, the negative pressure channel 21 forms a negative pressure port 22 above the tub 1 to communicate with the tub 1. The air in the tub 1 is collected to the position of the negative pressure port 22 and enters the negative pressure passage 21 through the negative pressure port 22. The negative pressure port 22 may be configured in the form of a passage opening commonly known in the art, such as a rectangle, a circle, a diamond, etc., without limitation.

With continued reference to fig. 3, the lowermost position of the water guard 41 is lower than the negative pressure port 22 in the height direction of the waster tub 1. With this configuration, after the liquid flows down from the lowest position of the water deflector 41, since the position where the liquid flows out of the water deflector 41 is lower than the negative pressure port 22, the air flow around the negative pressure port 22 cannot overcome the gravity of the liquid, and the liquid is brought into the negative pressure port 22, further preventing the liquid from entering the negative pressure passage 21 through the negative pressure port 22.

Referring to fig. 5, in one embodiment of the present disclosure, the lower end of the water-blocking chamber is lower than the negative pressure port 22. In the process that liquid enters the sewage bucket 1, the liquid impacts the water baffle plate 41 to diffuse around, and then flows downwards along the side wall of the water blocking cavity, the lower end of the water blocking cavity is lower than the negative pressure port 22, so that the air flow around the negative pressure port cannot overcome the gravity of the liquid to bring the liquid into the negative pressure port 22, and the liquid is further prevented from entering the negative pressure channel 21 through the negative pressure port 22.

Referring to fig. 6, in an embodiment of the present disclosure, a filter member 221 is further disposed at the position of the negative pressure port 22 of the negative pressure channel 21, and the filter member 221 may have a through hole 411 for allowing gas to pass therethrough. When the cleaning device is used, the air flow in the sewage bucket 1 enters the negative pressure channel 21 through the filtering piece 221 and the negative pressure port 22, and the water vapor or solid foreign matters mixed in the air flow are filtered by the filtering piece 221 so as to prevent the liquid and the solid foreign matters from entering the negative pressure channel 21 along with the air flow.

Referring to fig. 3 and 5, in one embodiment of the present disclosure, the opening direction of the negative pressure port 22 is away from the direction of the open end of the water-blocking chamber. Referring to the view direction of fig. 3, the inner walls of the opposite sides of the interior of the slop pail 1 are respectively referred to as a first side wall 111 and a second side wall 112. Wherein the negative pressure port 22 opens toward the first side wall 111 of the tub 1, and the open end of the water blocking chamber opens toward the inner wall of the tub 1 opposite to the side where the negative pressure port 22 opens, i.e., toward the second side wall 112. Because the airflow velocity around the opening of the negative pressure port 22 is large, the influence of the airflow around the negative pressure port 22 on the flow of the liquid can be reduced by increasing the distance between the opening of the negative pressure port 22 and the opening end of the water retaining chamber and enabling the direction of the opening end to be opposite to the direction of the negative pressure port 22, so that the liquid can smoothly flow down along the inner wall of the sewage bucket 1 on one side of the water retaining chamber.

Referring to fig. 5 and 7, in one embodiment of the present disclosure, the bottom of the negative pressure channel 21 includes a planar section 23, and an inclined section 24 connected to the planar section 23. The edge of the plane section 23 extends to the negative pressure port 22, and the inclined section 24 extends from the position connected with the plane section 23 toward the top of the slop pail 1. The inclined section 24 is higher than the planar section 23 so that moisture passing through the inclined section 24 can be reduced.

Referring to fig. 1 and 2, in an embodiment of the present disclosure, the slop pail 1 includes a pail body 11 having an open end, and a cover 12 for sealing the open end of the pail body 11, the negative pressure channel 21 and the water-blocking mechanism are disposed on the cover 12, and a sealing structure, such as a sealing ring, etc. commonly used in the art, can be disposed at the joint of the pail body 11 and the cover 12 to prevent the liquid in the slop pail 1 from leaking out, and will not be described in detail herein.

For example, after the wastebasket 1 is detached from the cleaning apparatus, the lid body 12 may be removed, the liquid stored in the tub body 11 may be dumped, and then the tub body 11 may be cleaned. Because the negative pressure channel 21 and the water retaining mechanism are both positioned on the cover body 12, the barrel body 11 has a simple structure, and the subsequent cleaning work is facilitated.

Referring to fig. 1 and 2, in an embodiment of the present disclosure, the negative pressure passage 21 forms a docking port 25 on the lid 12, an air outlet passage 26 is provided in the tub 11, the docking port 25 communicates with the air outlet passage 26 after the lid 12 is configured to be mounted to the tub 11, and a sealing structure may be further provided between the docking port 25 and the air outlet passage 26 to prevent air leakage. The sealing structure may be a sealing ring, etc. which are commonly used in the art and will not be described in detail herein.

Following the above embodiment, one end of the negative pressure channel 21 is the negative pressure port 22, and the other end is the interface 25, and one end of the air outlet channel 26 is connected to the interface 25, and the other end can be connected to the external air duct. In use, air flow enters the negative pressure port 22 from the inner cavity of the slop pail 1, passes through the plane section 23, the inclined section 24, the butt joint port 25 and the air outlet channel 26, and enters the external air duct, so that negative pressure is formed in the slop pail 1.

Referring to fig. 2, in an embodiment of the present disclosure, the interface 25 and the water blocking cavity of the negative pressure channel 21 are located on the same side of the cover 12, the negative pressure port 22 of the negative pressure channel 21 is located on the other side of the cover 12, and referring to the view direction, the interface 25 and the water blocking cavity are located on the right side of the central axis of the cover 12, and the negative pressure blocking port 22 is located on the left side of the central axis of the cover 12. The flowing process of the external liquid into the slop pail 1 all occurs on the same side of the cover body 12, and the air suction of the negative pressure channel 21 occurs on the other side of the cover body 12, so that the external liquid is prevented from being sucked by the negative pressure channel 21 after entering the slop pail 1, and the length of the negative pressure channel 21 can be increased through the arrangement, so that the structure is more compact.

Referring to fig. 2 and 5, the negative pressure port 22 may extend from a position corresponding to the docking port 25 to a position corresponding to the water blocking chamber on the cover 12, that is, the docking port 25 and the water blocking chamber are located in a projection of the negative pressure port 22 to the docking port 25 and one side of the water blocking chamber, thereby increasing an air inlet area of the negative pressure port 22, reducing a flow rate of air around the negative pressure port 22, and preventing liquid in the slop pail 1 from being sucked into the negative pressure channel 21 due to an excessive flow rate of the air.
